PART I

Item 1. Business.

Unless the context requires otherwise, references to (i) “we,” “us,” “our,” “our company,” the “Company,” “Crestwood Midstream,” and like terms refer to Crestwood Midstream Partners LP and its consolidated subsidiaries, (ii) “Legacy Inergy” refers to Inergy Midstream, L.P. and its consolidated subsidiaries prior to the Crestwood Merger (defined below), and (iii) “Legacy Crestwood” refers to Crestwood Midstream Partners LP and its consolidated subsidiaries prior to the Crestwood Merger. Unless otherwise indicated, information contained herein is reported as of December 31, 2013.

As explained below and in Part IV, Item 15, Exhibits and Financial Statement Schedules, Notes 1 and 2, the merger of Legacy Crestwood with and into Legacy Inergy in October 2013 was accounted for as a reverse merger under the purchase method of accounting. Legacy Crestwood is therefore treated as the acquirer of Legacy Inergy for accounting purposes, whereas Legacy Inergy is the survivor of the merger (and successor by merger to Legacy Crestwood) for legal purposes. Notwithstanding this distinction, references in this Part I to “we,” “us,” “our,” “our company,” the “Company,” and “Crestwood Midstream” refer to the combined operations of the partnerships unless the context requires otherwise.

Introduction

Crestwood Midstream, a Delaware limited partnership formed in November 2011, is a growth-oriented master limited partnership ("MLP") that develops, acquires, owns and operates primarily fee-based assets and operations within the energy midstream sector. Headquartered in Houston, Texas, we provide broad-ranging infrastructure solutions across the value chain to service premier liquids-rich and crude oil shale plays across the United States. Our common units representing limited partner interests are listed on the NYSE under the symbol “CMLP”.

We own and operate a diversified portfolio of crude oil and natural gas gathering, processing, storage and transportation assets that connect fundamental energy supply with energy demand across North America. Our consolidated operating assets include:

• natural gas facilities with approximately 2.5 Bcf/d of gathering capacity, 471 MMcf/d of processing capacity,

1.0 Bcf/d of firm transmission capacity, and 41 Bcf of working gas storage capacity;

• NGL facilities with approximately 1.7 million barrels of storage capacity; and

• crude oil facilities with approximately 100,000 Bbls/d of gathering capacity, 960,000 barrels of storage capacity, and 120,000 Bbls/d of rail loading capacity.

Our primary business objective is to increase the cash distributions that we pay to our unitholders by growing our business safely through the development, acquisition and operation of additional midstream assets situated near developed and emerging shale resources and premium demand centers. We expect to increase cash available for distribution to our unitholders through organic growth and increased operational efficiencies, including commercial and operational synergies resulting from the Crestwood Merger. We also anticipate growing our business through strategic and bolt-on acquisitions, including asset drop downs, with an emphasis on acquisitions that further expand our existing asset footprint and the combination of value chain services we provide for our customers.

Ownership Structure

The diagram below reflects a simplified version of our ownership structure as of December 31, 2013:

7

We were formed by Crestwood Equity Partners LP (formerly known as Inergy, L.P., “Crestwood Equity” or “CEQP”) on November 14, 2011. We were formed by converting Inergy Midstream, LLC from a Delaware limited liability company into a Delaware limited partnership named Inergy Midstream, L.P. This conversion occurred as part of our initial public offering, which closed December 21, 2011.

On October 7, 2013, the operations of our company and Legacy Crestwood were combined when (i) one of our wholly-owned subsidiaries merged with and into Legacy Crestwood, with Legacy Crestwood surviving the merger and becoming a wholly-owned subsidiary of us, and (ii) Legacy Crestwood immediately thereafter merged with and into our company (collectively, the “Crestwood Merger”). Contemporaneously with the Crestwood Merger, we changed our name to Crestwood Midstream Partners LP and changed our NYSE listing symbol to “CMLP.” See Part IV, Item 15, Exhibits and Financial Statement Schedules, Note 1 for additional information on the Crestwood Merger and certain transactions related thereto.

Our non-economic general partner interest is held by Crestwood Midstream GP LLC, which we refer to as our “general partner” and which is owned by CEQP. CEQP also owns 100% of our incentive distribution rights (“IDRs”) and, as of December 31, 2013, approximately 4% of our common units representing limited partnership interests. Given that CEQP owns and controls our general partner, and the entity that owns and controls CEQP’s general partner is substantially owned and controlled by First Reserve Management, L.P. (“First Reserve”), we are effectively controlled by First Reserve.

Our Assets

We have three reporting segments: (i) gathering and processing, (ii) NGL and crude services, and (iii) storage and transportation.

Gathering and Processing

We provide natural gas gathering, processing, treating and compression services to producers in unconventional shale plays located in West Virginia, Wyoming, Texas, Arkansas, New Mexico and Louisiana. We own rich gas systems in the Marcellus, Powder River Basin (“PRB”) Niobrara, Barnett, Granite Wash, and Avalon/Bone Spring Shale plays, and dry gas gathering systems in the Barnett, Fayetteville and Haynesville/Bossier Shale plays.

The table below summarizes certain information about our gathering and processing systems as of December 31, 2013:

Shale Play (State)	Counties / Parishes	Pipeline (Miles)	Gathering Capacity (MMcf/d)	Average Gathering Volume (MMcf/d)	Compression (HP)	Number of In-Service Processing Plants	Processing Capacity (MMcf/d)	Gross Acreage Dedication

(1) Our PRB Niobrara assets are owned by Jackalope Gas Gathering Services, L.L.C., our 50% owned equity-method investment. The average gathering volumes represent the average volumes for the period of acquisition (July 19, 2013) to December 31, 2013.

8

We generate G&P revenues predominantly under fee-based contracts, which minimizes our commodity price exposure and provides less volatile operating performance and cash flows. Our principal G&P systems are described below.

Marcellus

We own and operate rich gas systems in Harrison and Doddridge Counties, West Virginia and a dry gas system in Barbour County, West Virginia. These systems consist of 65 miles of low pressure gathering lines and seven compression and dehydrations stations with 82,340 horsepower. Our current operations are predominantly focused on our rich gas systems. On these systems, we provide midstream services to Antero Resources (“Antero”), which is the most active upstream developer of the rich gas corridor of the southwestern core of the Marcellus Shale play. We provide our services under long-term, fixed-fee contracts across two operating areas, our eastern area of operation (“East AOD”) and our western area of operation (“Western Area”).

In the East AOD, we provide gathering, dehydration and compression services to Antero in an approximately 140,000 gross acre area from which Antero has dedicated all production of rich natural gas to our system pursuant to a 20-year, fixed-fee gathering and compression agreement. As a part of that agreement, we gather and deliver Antero’s production to MarkWest Energy Partners’ Sherwood Gas Processing Plant and various regional pipeline systems. Antero has provided minimum volume commitments under our agreement, which increase from an average of 400 MMcf/d in 2014 up to an average of 450 MMcf/d in 2016, 2017 and 2018, respectively. Our system is currently connected to 173 wells and current average daily volumes delivered to our system have increased by over 180% from when we acquired the assets in 2012.

In the Western Area, we provide compression and dehydration services to Antero’s gathering facilities predominantly with our West Union and Victoria compressor stations. We provide services to Antero under a five year, fixed-fee agreement that runs through 2018, subject to Antero’s right to extend the contract term for an additional five years. Although volumes compressed from these stations are not contractually dedicated to us in the Western Area, Antero does provide minimum volume commitments up to 50% of the throughput capacity of each compressor station. We also hold a right of first offer until 2019 to acquire and develop any midstream facilities developed by Antero in the Western Area for ultimate transfer or sale to a third party.

We estimate that Antero has developed less than 10% of its available drilling locations on its West Virginia Marcellus Shale acreage, and as a result, we expect to continue to materially expand our systems in both the East AOD and Western Area to service Antero’s continued growth in throughput. We invested approximately $236 million in our Marcellus systems during the year ended December 31, 2013, bringing our total capital invested in these systems to approximately $726 million since acquiring them in 2012.

PRB Niobrara

Our G&P segment includes our 50% interest in Jackalope Gas Gathering Services, L.L.C. (“Jackalope”), which owns a gas gathering system being developed to support a 311,000 gross acre AOD operated by Chesapeake Energy Corporation (“Chesapeake”) and RKI Exploration and Production LLC (“RKI”) in the core of the PRB Niobrara Shale. The Jackalope system, which is 50% owned and operated by Access Midstream Partners, L.P., consists of approximately 146 miles of gathering pipelines and 15,600 horsepower of compression equipment located in Converse County, Wyoming. The existing system, which connects to 115 wells, and its planned future development are supported by a 20-year gathering and processing agreement with Chesapeake and RKI under which Jackalope receives cost-of-service based fees with annual redeterminations sufficient to provide Jackalope a fixed return on all capital invested to build out and expand the system over the life of the contract. Crestwood Niobrara manages the commercial operations of Jackalope.

We invested approximately $128 million in Jackalope in fiscal 2013. Our Jackalope interest, which we acquired in July 2013, was financed in part through a joint venture formed by our consolidated subsidiary, Crestwood Niobrara LLC (“Crestwood Niobrara”), with General Electric Capital Corporation and GE Structured Finance, Inc. (collectively, "GE"). See Part IV, Item 15, Exhibits and Financial Statement Schedules, Notes 5 and 9 for additional information on our Jackalope acquisition and financing thereof.

Barnett

We own and operate three systems in the Barnett Shale, including the Cowtown, Lake Arlington and the Alliance systems.

Our Cowtown system, which is located principally in the southern portion of the Fort Worth Basin, consists of (i) pipelines that gather rich natural gas produced by customers and delivers the volumes to our plants for processing, (ii) the Cowtown plant, which includes two natural gas processing units that extract NGLs from the natural gas stream and deliver customers’ residue gas and extracted NGLs to unaffiliated pipelines for sale downstream, and (iii) the Corvette plant, which extracts NGLs from the natural gas stream and delivers customers’ residue gas and extracted NGLs to unaffiliated pipelines for sale downstream. For the year ended December 31, 2013, our Cowtown and Corvette plants had a total average throughput of 189 MMcf/d of natural gas with an average NGL recovery of 19,600 Bbl/d.

Our Lake Arlington system, which is located in eastern Tarrant County, Texas, consists of a gas gathering system and related compression facility. Our Alliance system, which is located in northern Tarrant and southern Denton Counties, Texas, consists of a gas gathering system and a related dehydration, compression and amine treating facility.

We also own the West Johnson County system in the Barnett, which was operational from the date we acquired the plant (August 24, 2012) until we ceased operating the plant on December 31, 2012. We have since diverted rich gas volumes to our other processing facilities and are currently evaluating other potential uses for the West Johnson County plant, which has a processing capacity of 100 MMcf/d of natural gas.

Fayetteville

We own and operate five systems in the Fayetteville Shale, including the Twin Groves, Prairie Creek, Woolly Hollow, Wilson Creek, and Rose Bud systems. Our Twin Groves, Prairie Creek, and Woolly Hollow systems (Conway and Faulkner Counties) consist of three gas gathering, compression, dehydration and treating facilities. Our Wilson Creek (Van Buren County) and Rose Bud system (White County) systems each consist of a gas gathering system and a related compression facility. All of our systems gather natural gas produced by customers and deliver customers’ gas to unaffiliated pipelines for downstream sale.

Other

We also own and operate systems in the Granite Wash, Avalon/Bone Spring, and the Haynesville/Bossier Shales. Our Indian Creek system, which is located in Roberts County, Texas in the Granite Wash, includes a rich gas gathering system, compression facility and processing plant. Our Las Animas system, which is located in Eddy County, New Mexico, consists of three gas gathering systems located in the Morrow/Atoka reservoir and the Avalon/Bone Spring Shale rich gas trend in the Permian Basin. Our Sabine system, which is located in Sabine Parish, Louisiana, includes high-pressure gas gathering pipelines that provide gathering and treating services for producers in the Haynesville/Bossier Shale.

See Part IV, Item 15, Exhibits and Financial Statement Schedules, Note 4 for information related to our acquisition of various G&P systems.

NGL and Crude Services

The operations comprising our NGL and crude segment primarily include crude oil rail terminals, the Arrow gathering system described below, an NGL storage facility, and US Salt, LLC (“US Salt”).

The COLT Hub consists of a crude oil loading and storage terminal and interconnecting pipeline facilities located in the heart of the Bakken and Three Forks Shale oil-producing areas in Williams County, North Dakota. It has 960,000 barrels of crude oil storage capacity and is capable of loading up to 120,000 Bbls/d utilizing two 8,700-foot rail loops that can accommodate 120-car unit trains. Customers can source crude oil through interconnected gathering systems, an eight-bay truck unloading rack and the COLT Connector, a 21-mile, 10-inch bi-directional pipeline that connects the COLT Hub to the Enbridge and Tesoro crude pipelines at Dry Fork (Beaver Lodge/Ramberg junction). The COLT Hub is connected to the Meadowlark Midstream Company, LLC (formerly, Bear Tracker Energy) and Hiland crude oil gathering systems, and the Enbridge and Tesoro pipeline systems. We acquired the COLT Hub for $425 million in December 2012, and since the acquisition we have invested a total of approximately $36.5 million in the COLT Hub to expand storage and rail loading capacity.

The Arrow system gathers crude oil, rich natural gas and produced water from wells operating on the Fort Berthold Indian Reservation in the core of the Bakken Shale in McKenzie and Dunn Counties, North Dakota.  The system, which is located approximately 60 miles southeast of the COLT Hub, connects to our COLT Hub through the Hiland and Tesoro crude oil

10

pipeline systems.  The Arrow system includes more than 485 miles of gathering lines (including approximately 153 miles of crude oil gathering pipeline, 171 miles of natural gas gathering pipeline, and 164 miles of produced water gathering lines), a 23-acre central delivery point with multiple pipeline take-away outlets and a fully-automated truck loading facility, and salt disposal wells.  Our operations are anchored by long-term, primarily fee-based gathering contracts with blue-chip producers who have dedicated over 150,000 acres to the Arrow system, and our underlying contracts provide for fixed-fee gathering services with annual escalators for crude oil, natural gas and produced water gathering services.  We are gathering approximately 48,300 Bbls/d of crude oil, 11.8 MMcf/d of rich natural gas and 10,500 Bbls/d of produced water on the Arrow system as of December 31, 2013.  We acquired the Arrow system in November 2013 for approximately $750 million, and since the acquisition we have invested approximately $24.9 million in the Arrow system.  See Part IV, Item 15, Exhibits and Financial Statements, Note 4 for additional information on our Arrow acquisition.

Our NGL and crude services segment also includes our approximate 50% interest in Power River Basin Industrial Complex, LLC (“PRBIC”), which owns an early stage crude oil rail terminal located in Douglas County, Wyoming that supports crude oil volumes produced within the PRB Niobrara. The rail loading terminal, which we jointly own with Enserco Midstream LLC, is capable of loading up to 6,000 Bbls/d on a manifest basis and is expected to commence unit train service in the first quarter of 2014. We paid approximately $22.5 million for our interest in PRBIC and we have invested approximately $1.9 million in PRBIC in 2013 since acquiring our equity interest. See Part IV, Item 15, Exhibits and Financial Statement Schedules, Note 5 for additional information on our PRBIC acquisition.

Our NGL storage assets include the Bath storage facility, a 1.7 million barrel NGL storage facility located near Bath, New York. The facility is located approximately 210 miles northwest of New York City. It is supported by both rail and truck terminal facilities capable of loading and unloading 23 railcars per day and approximately 100 truck transports per day.

US Salt is an industry-leading solution mining and salt production company located on the shores of Seneca Lake near Watkins Glen in Schuyler County, New York. It is one of five major solution mined salt manufacturers in the United States, capable of producing more than 400,000 tons of evaporated salt products for food, industrial and pharmaceutical uses. The solution mining process used by US Salt creates salt caverns that can be converted into natural gas and NGL storage capacity.

Storage and Transportation

We own and operate four high-performance natural gas storage facilities located in New York and Pennsylvania that have an aggregate working gas storage capacity of approximately 41.0 Bcf, which we believe makes us the largest independent natural gas storage provider in the Northeast. Our storage facilities have low maintenance costs, long useful lives and comparatively high cycling capabilities. The interconnectivity of our storage facilities with interstate pipelines offers flexibility to shippers in the Northeast, and our facilities are located in close proximity to the Northeast demand market and a prolific supply source, the Marcellus Shale. Our natural gas storage facilities, each of which generates fee-based revenues and whose operationally available storage capacity has been 100% contracted, include:

• Stagecoach, a 26.2 Bcf multi-cycle, depleted reservoir storage facility owned and operated by our Central New York Oil And Gas Company, L.L.C. (“CNYOG”) subsidiary. A 24-mile, 30-inch diameter south pipeline lateral connects the storage facility to Tennessee Gas Pipeline Company, LLC's (“TGP”) 300 Line, and a 10-mile, 20-inch diameter north pipeline lateral connects to the Millennium Pipeline (“Millennium”);

• Thomas Corners, a 7.0 Bcf multi-cycle, depleted reservoir storage facility owned and operated by our Arlington Storage Company, LLC (“Arlington Storage”) subsidiary. An 8-mile, 12-inch diameter pipeline lateral connects the storage facility to TGP's 400 Line, and a 7.5-mile, 8-inch diameter pipeline lateral connects to Millennium. Thomas Corners is also connected to Dominion Transmission Inc. (“Dominion”) system through our Steuben facility;

• Steuben, a 6.3 Bcf single-turn, depleted reservoir storage facility owned and operated by Arlington Storage. A 12.5-mile, 12-inch diameter pipeline lateral connects the storage facility to the Dominion system, and a 6-inch diameter pipeline measuring less than one mile connects our Steuben and Thomas Corners storage facilities; and

• Seneca Lake, a 1.5 Bcf multi-cycle, bedded salt storage facility owned and operated by Arlington Storage. A 19-mile, 16-inch diameter pipeline lateral connects the storage facility to Millennium and Dominion’s system. We acquired the Seneca Lake facility from New York State Electric & Gas Corporation (“NYSEG”) in July 2011.

(1) Stagecoach is connected to Transco's Leidy Line through our MARC I Pipeline.

(2) Seneca Lake was designed for 12-turn service, but we operate it as a nine-turn high-deliverability storage facility.

We own natural gas transportation facilities located in New York and Pennsylvania. These facilities have low maintenance costs and long useful lives, and they are located in or near the Marcellus Shale. Throughput on our transportation assets can also be expanded at relatively low capital costs. In 2013, our transportation facilities delivered approximately 0.8 Bcf/d of natural gas on a firm or interruptible basis. Our natural gas transportation facilities include:

• North-South Facilities, which include compression and appurtenant facilities installed to expand transportation capacity on the Stagecoach north and south pipeline laterals. The bi-directional facilities, which are owned and operated by CNYOG, provide more than 365 MMcf/d of firm interstate transportation capacity to shippers. The North-South Facilities, which were placed into service in December 2011, generate fee-based revenues under a negotiated rate structure authorized by the FERC;

• MARC I Pipeline, a 39-mile, 30-inch diameter interstate natural gas pipeline that connects the Stagecoach south lateral and TGP's 300 Line in Bradford County, Pennsylvania, with Transcontinental Gas Pipe Line Company, LLC's (“Transco”) Leidy Line in Lycoming County, Pennsylvania. The bi-directional pipeline, which is owned and operated by CNYOG, provides more than 590 MMcf/d of firm interstate transportation capacity to shippers. It includes a 16,360 horsepower gas-fired compressor station near the Transco interconnection, and a 15,000 horsepower electric-powered compressor station at the interconnection between the Stagecoach south lateral and TGP’s 300 Line. The MARC I Pipeline, which placed into service in December 2012, generates fee-based revenues under a negotiated rate structure authorized by the FERC; and

• East Pipeline,a 37.5 mile, 12-inch diameter natural gas intrastate pipeline located in New York, which transports 30 MMcf/d of natural gas from Dominion to the Binghamton, New York city gate. The pipeline, which is owned and operated by our Crestwood Pipeline East, LLC (formerly Inergy Pipeline East, LLC, “CPE”) subsidiary, runs within three miles of our Stagecoach north lateral's point of interconnection with Millennium. The East Pipeline generates fee-based revenues under a negotiated rate structure authorized by the New York State Public Service Commission (“NYPSC”). We acquired the East Pipeline from NYSEG in July 2011 as part of our acquisition of the Seneca Lake gas storage facility.

Growth Projects

Gathering and Processing

We are expanding our gathering and compression facilities in the Marcellus Shale to accommodate Antero’s increased drilling activity and accelerated production plans. Based on our existing construction plans and Antero’s latest production plans, we expect to spend between $180 million and $220 million in 2014 to construct additional gathering lines and four compressor stations. As a result of this additional installed system capacity, we expect daily gathering volumes for all of our gathering and processing operations to increase from approximately 500 MMcf/d at December 31, 2013 to approximately 750 MMcf/d by December 31, 2014.

12

We are working with our joint venture partner to build out the Jackalope gathering system and to construct a 120 MMcf/d processing facility (Bucking Horse Plant) to serve PRB Niobrara producers, including Chesapeake and RKI. In December 2013, Jackalope received the state permit required to commence construction of the gas processing plant, and we anticipate that Jackalope will commence processing volumes at the cryogenic plant in the fourth quarter of 2014. We expect the processing plant to produce more than 9,000 barrels of NGLs daily at full capacity, and we anticipate that Jackalope will spend approximately $237 million on the system build out next year. We anticipate that Jackalope will complete the build-out of its system to reach a total design capacity of 150 MMcf/d of gas gathering by the third quarter of 2014.

NGL and Crude Services

We are continuing to build out the Arrow gathering system to its total design capacity of 125,000 Bbls/d of crude oil gathering, 100 MMcf/d of gas gathering, and 40,000 Bbls/d of produced water gathering. We also substantially completed in late 2013 certain system enhancements (including line looping and system compression) that will enable us to capture greater volumes of natural gas currently being flared by producers, and we expect to complete these enhancements in the first half of 2014. Given that the Arrow system was designed and constructed to handle significantly greater volumes than those flowing today and that our producer customers are responsible for the costs of connecting their wells to our system, we expect to complete the Arrow system build-out to reach targeted operational throughput capacities with modest organic capital requirements (approximately $80 million) over the next 18-24 months.

We are expanding our COLT Hub to increase our crude oil throughput and storage capacities. The expansion primarily entails the installation of additional crude oil loading arms and pumps at our rail loading rack; the construction of parallel rail tracks on which we will be able to store additional unit trains; the construction of two floating-roof crude oil storage tanks; the construction of additional truck unloading racks; and modifications that will enable us to receive more crude oil from interconnected gathering systems. The expansion is designed to increase our unit train loading capacity to 160,000 Bbls/d, our truck unloading capacity to 96,000 Bbls/d, our working storage capacity to 1.08 million barrels, and our input capacity from third-party gathering systems to approximately 105,000 Bbls/d. We estimate the total capital cost of this expansion to be approximately $52.0 million, and we have entered into customer contracts that support a substantial portion of our anticipated capital investment. We expect to complete the expansion in the first quarter of 2014.

We are developing an NGL storage facility at our US Salt complex in Schuyler County, New York. We have requested from the New York State Department of Environmental Conservation (“NYSDEC”) the permits necessary to store up to 2.1 million barrels of propane and butane in underground caverns created by US Salt’s solution-mining process. We estimate that the total capital cost of our proposed Watkins Glen NGL storage project to be approximately $40.3 million. We expect the NYSDEC to issue the requested permits in 2014 and to place the storage facility into service within 90-120 days thereafter, but we can provide no assurances that we will receive, if at all, the permits necessary to commence construction.

Storage and Transportation

We have requested the regulatory approvals (including FERC authorization) necessary to expand the working gas capacity of our Seneca Lake natural gas storage facility by approximately 0.5 Bcf. We estimate the total capital cost of this expansion to be approximately $2.0 million. We expect to place this expansion capacity into service in the first half of 2014.

Customers

For the fiscal year ended December 31, 2013, Quicksilver Resources Inc. (“Quicksilver”) and Antero accounted for approximately 15% and 10% of our total consolidated revenues. For the fiscal year ended December 31, 2012, Quicksilver and Antero accounted for approximately 47% and 11% of our total consolidated revenues. For the fiscal year ended December 31, 2011, Quicksilver accounted for approximately 64% of our total consolidated revenues.

Industry Background

The midstream sector of the energy industry provides the link between exploration and production and the delivery of crude oil, natural gas and their components to end-use markets. The midstream sector consists generally of gathering, processing, storage, and transportation activities. We gather crude oil and natural gas; process natural gas; store crude oil, natural gas and NGLs; and transport crude oil and natural gas.

13

The diagram below depicts the main segments of the midstream sector value chain:

Crude Oil

Pipelines typically provide the most cost-effective option for shipping crude oil. Crude oil gathering systems normally comprise a network of small-diameter pipelines connected directly to the well head that transport crude oil to central receipt points or interconnecting pipelines through larger diameter trunk lines. Common carrier pipelines frequently transport crude oil from central delivery points to logistics hubs or refineries under tariffs regulated by the FERC or state authorities. Logistic hubs provide storage and connections to other pipeline systems and modes of transportation, such as railroads and trucks. Pipelines not engaged in the interstate transportation of crude may also be proprietary or leased entirely to a single customer.

Trucking complements pipeline gathering systems by gathering crude oil from operators at remote wellhead locations not served by pipeline gathering systems. Trucking is generally limited to low volume, short haul movements because trucking costs escalate sharply with distance, making trucking the most expensive mode of crude oil transportation. Railroads provide additional transportation capabilities for shipping crude oil between gathering storage systems, pipelines, terminals and storage centers and end-users.

Natural Gas

Midstream companies within the natural gas industry create value at various stages along the value chain by gathering natural gas from producers at the wellhead, processing and separating the hydrocarbons from impurities and into lean gas (primarily methane) and NGLs, and then routing the separated lean gas and NGL streams for delivery to end-markets or to the next stage of the value chain.

A significant portion of natural gas produced at the wellhead contains NGLs. Natural gas produced in association with crude oil typically contains higher concentrations of NGLs than natural gas produced from gas wells. This rich natural gas is generally not acceptable for transportation in the nation’s transmission pipeline system or for residential or commercial use. Processing plants extract the NGLs, leaving residual lean gas that meets transmission pipeline quality specifications for ultimate consumption. Processing plants also produce marketable NGLs, which, on an energy equivalent basis, typically have a greater economic value as a raw material for petrochemicals and motor gasolines than as a component of the natural gas stream.

Gathering.At the earliest stage of the midstream value chain, a network of typically small diameter pipelines known as gathering systems directly connect to wellheads or pad sites in the production area. Gathering systems transport gas from the wellhead to downstream pipelines or a central location for treating and processing. Gathering systems are often designed to be highly flexible to allow gathering of natural gas at different pressures and scalable to allow for additional production and well connections without significant incremental capital expenditures. A byproduct of the gathering process is the recovery of condensate liquids, which are sold on the open market.

14

Compression.Gathering systems are operated at pressures intended to enable the maximum amount of production to be gathered from connected wells. Through a mechanical process known as compression, volumes of natural gas at a given pressure are compressed to a sufficiently higher pressure, thereby allowing those volumes to be delivered into a higher pressure downstream pipeline to be shipped to market. Because wells produce at progressively lower field pressures as they age, it becomes necessary to add additional compression over time to maintain throughput across the gathering system.

Treating and Dehydration.Treating and dehydration involves the removal of impurities such as water, carbon dioxide, nitrogen and hydrogen sulfide that may be present when natural gas is produced at the wellhead. Impurities must be removed for the natural gas to meet the quality specifications for pipeline transportation, and end users normally cannot consume (and will not purchase) natural gas with a high level of impurities. Therefore, to meet downstream pipeline and end user natural gas quality standards, the natural gas is dehydrated to remove water and is chemically treated to separate the impurities from the natural gas stream.

Processing.Once impurities are removed, pipeline-quality residue gas is separated from NGLs. Most rich natural gas is not suitable for long-haul pipeline transportation or commercial use and must be processed to remove the heavier hydrocarbon components. The removal and separation of hydrocarbons during processing is possible because of the differences in physical properties between the components of the raw gas stream. There are four basic types of natural gas processing methods: cryogenic expansion, lean oil absorption, straight refrigeration and dry bed absorption. Cryogenic expansion represents the latest generation of processing, incorporating extremely low temperatures and high pressures to provide the best processing and most economical extraction.

Natural gas is processed not only to remove heavier hydrocarbon components that would interfere with pipeline transportation or the end use of the natural gas, but also to separate from the natural gas those hydrocarbon liquids that could have a higher value as NGLs than as natural gas. The principal component of residue gas is methane, although some lesser amount of entrained ethane typically remains. In some cases, processors have the option to leave ethane in the gas stream or to recover ethane from the gas stream, depending on ethane’s value relative to natural gas. The processor’s ability to “reject” ethane varies depending on the downstream pipeline’s quality specifications. The residue gas is sold to industrial, commercial and residential customers and electric utilities.

Transportation and Storage.Once raw natural gas has been treated or processed and the raw NGL mix fractionated into individual NGL components, the natural gas and NGL components are stored, transported and marketed to end-use markets. The natural gas pipeline grid in the United States transports natural gas from producing regions to customers, such as LDCs, industrial users and electric generation facilities.

Historically, the concentration of natural gas production in a few regions of the United States generally required transportation pipelines to transport gas not only within a state but also across state borders to meet national demand. However, a recent shift in supply sources, from conventional to unconventional, has affected the supply patterns, the flows and the rates that can be charged on pipeline systems. The impacts vary among pipelines according to the location and the number of competitors attached to these new supply sources. These changing market dynamics are prompting midstream companies to evaluate the construction of short-haul pipelines as a means of providing demand markets with cost-effective access to newly-developed production regions, as compared to relying on higher-cost, long-haul pipelines that were originally designed to transport natural gas greater distances across the country.

Natural gas storage plays a vital role in maintaining the reliability of gas available for deliveries. Natural gas is typically stored in underground storage facilities, including salt dome caverns, bedded salt caverns and depleted reservoirs. Storage facilities are most often utilized by pipeline companies to manage temporary imbalances in operations; natural gas end-users, such as LDCs, to manage the seasonality and variability of demand and to satisfy future natural gas needs; and, independent natural gas marketing and trading companies in connection with the execution of their trading strategies.

Salt Manufacturing

According to the United States Geological Survey, approximately 280 million metric tons of salt were produced in the world in 2012. Salt is generally categorized into four types based upon the method of production: evaporated salt, solar salt, rock salt and salt in brine. Dry salt is produced through the following methods: solution mining and mechanical evaporation, solar evaporation or deep-shaft mining. US Salt produces salt using solution mining and mechanical evaporation. In solution mining, wells are drilled into salt beds or domes and then water is injected into the formation and circulated to dissolve the salt. After salt is removed from a solution-mined salt deposit, the empty cavern can be used to store other substances, such as natural gas, NGLs or compressed air.

15

The salt solution, or brine, is next pumped out of the cavern and taken to a processing plant for evaporation. The brine may be treated to remove minerals and then pumped into vacuum pans in which the brine is boiled, and evaporated until a salt slurry is created. The slurry is then dried and separated. Depending on the type of salt product to be produced, iodine and an anti-caking agent may be added to the salt. Most food grade table salt is produced in this manner.

Competition

Our G&P operations compete for customers based on reputation, operating reliability and flexibility, price, creditworthiness, and service offerings, including interconnectivity to producer-desired takeaway options (e.g., processing facilities and pipelines). We face strong competition in acquiring new supplies in the production basins in which we operate, and competition customarily is impacted by the level of drilling activity in a particular geographic region and fluctuations in commodity prices. Our primary competitors include other midstream companies with G&P operations and producer-owned systems, and certain competitors enjoy first-mover advantages over us and may offer producers greater gathering and processing efficiencies, lower operating costs and more flexible commercial terms.

Natural gas storage and pipeline operators compete for customers primarily based on geographic location, which determines connectivity and proximity to supply sources and end-users, as well as price, operating reliability and flexibility, available capacity and service offerings. Our primary competitors in our natural gas storage market include other independent storage providers and major natural gas pipelines with storage capabilities embedded within their transmission systems. Our primary competitors in our natural gas transportation market include major natural gas pipelines and intrastate pipelines that can transport natural gas volumes between interstate systems. Long-haul pipelines often enjoy cost advantages over new pipeline projects with respect to options for delivering greater volumes to existing demand centers, and new projects and expansions proposed from time to time may serve the markets we serve and effectively displace the service we provide to customers.

Our crude oil rail terminals primarily compete with crude oil pipelines and other midstream companies that own and operate rail terminals in the markets we serve. The crude oil logistics business is characterized by strong completion for supplies, and competition is based largely on customer service quality, pricing, and geographic proximity to customers and other market hubs.

Our salt operations compete for customers primarily based on price and service. Because transportation costs are a material component of the costs borne by our customers, most of our customers are geographically located east of the Mississippi River.

Regulation

Our operations are subject to extensive regulation by federal, state and local authorities. The regulatory burden on our operations increases our cost of doing business and, in turn, impacts our profitability. In general, midstream companies have experienced increased regulatory oversight over the past few years, and we expect this trend to continue for the foreseeable future.

Pipeline Safety

We are subject to pipeline safety regulations imposed by the Department of Transportation Pipeline and Hazardous Materials Safety Administration (“PHMSA”). PHMSA regulates safety requirements in the design, construction, operation and maintenance of jurisdictional natural gas and hazardous liquid pipeline facilities. Currently, all of our natural gas pipelines used in gathering, storage and transportation activities are subject to regulation by PHMSA under the Natural Gas Pipeline Safety Act of 1968, as amended, and all of our NGL and crude oil pipelines used in gathering, storage and transportation activities are subject to regulation by PHMSA as hazardous liquids pipelines under the Hazardous Liquid Pipeline Safety Act of 1979, as amended.

These federal statutes and PHMSA implementing regulations collectively impose numerous safety requirements on pipeline operators, such as the development of a written qualification program for individuals performing covered tasks on pipeline facilities and the implementation of pipeline integrity management programs. For example, the Pipeline Safety Improvement Act of 2002 establishes mandatory inspections for all crude oil and natural gas transmission pipelines in high-consequence areas, such as areas of high population and areas unusually sensitive to environmental damage. Integrity management plans require more frequent inspections and other preventative measures to ensure pipeline safety in high consequence areas.

We plan to continue our pipeline integrity testing programs to assess and maintain the integrity of our pipelines in accordance with PHMSA regulations. Notwithstanding our preventive and investigatory maintenance efforts, we may incur significant expenses if anomalous pipeline conditions are discovered or due to the implementation of more stringent pipeline safety

16

standards resulting from new or amended legislation. For example, President Obama in January 2012 signed the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (“Pipeline Safety Act”), which requires increased safety measures for gas and hazardous liquids transportation pipelines. Among other things, the Pipeline Safety Act directs the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, automatic or remote-controlled valve use, excess flow valve use, and leak detection system installation. The Pipeline Safety Act also directs owners and operators of interstate and intrastate gas transmission pipelines to verify their records confirming the maximum allowable pressure of pipelines in certain class locations and high consequence areas, requires promulgation of regulations for conducting tests to confirm the material strength of pipe operating above 30% of specified minimum yield strength in high consequence areas, and increases the maximum penalty for violation of pipeline safety regulations from $1 million to $2 million. Furthermore, PHMSA is considering changes to its natural gas transmission pipeline regulations to, among other things, expand the scope of high consequence areas, strengthen integrity management requirements applicable to existing operators; strengthen or expand non-integrity pipeline management standards relating to such matters as valve spacing, automatic or remotely-controlled valves, corrosion protection, and gathering lines; and add new regulations to govern the safety of underground natural gas storage facilities, including underground storage caverns and injection or withdrawal well piping that are not regulated today. We cannot predict the final outcome of these legislative or regulatory efforts or the precise impact that compliance with any resulting new requirements may have on our business.

States are largely preempted by federal law from regulating pipeline safety for interstate lines, but most are certified by the Department of Transportation to assume responsibility for enforcing federal intrastate pipeline regulations and inspection of intrastate pipelines. In practice, because states can adopt stricter standards for intrastate pipelines than those imposed by the federal government for interstate pipelines, states vary considerably in their authority and capacity to address pipeline safety. Our pipelines have operations and maintenance plans designed to keep the facilities in compliance with pipeline safety requirements, and we do not anticipate any significant difficulty in complying with applicable state laws and regulations.

Natural Gas Storage and Transportation

Our interstate natural gas storage and transportation operations are subject to regulation by the FERC under the Natural Gas Act, and two of our subsidiaries (CNYOG and Arlington Storage) are regulated by the FERC as natural gas companies. Under the Natural Gas Act, the FERC has authority to regulate gas transportation services in interstate commerce, which includes natural gas storage services. The FERC exercises jurisdiction over rates charged for services and the terms and conditions of service; the certification and construction of new facilities; the extension or abandonment of services and facilities; the maintenance of accounts and records; the acquisition and disposition of facilities; standards of conduct between affiliated entities; and various other matters. Regulated natural gas companies are prohibited from charging rates determined by the FERC to be unjust, unreasonable, or unduly discriminatory, and both the existing tariff rates and the proposed rates of regulated natural gas companies are subject to challenge.

The rates and terms and conditions of our natural gas storage and transportation services are found in the FERC-approved tariffs of (i) CNYOG, the owner of the Stagecoach facility, the North-South Facilities and the MARC I Pipeline, and (ii) Arlington Storage, the owner of the Thomas Corners, Seneca Lake and Steuben facilities. CNYOG and Arlington Storage are authorized to charge and collect market-based rates for storage services, and CNYOG is authorized to charge and collect negotiated rates for transportation services. Market-based and negotiated rate authority allows us to negotiate rates with individual customers based on market demand, which we then make public. A loss of market-based or negotiated rate authority or any successful complaint or protest against the rates charged or provided by CNYOG or Arlington Storage could have an adverse impact on our revenues.

In addition, the Energy Policy Act of 2005 amended the Natural Gas Act to (i) prohibit market manipulation by any entity; (ii) direct the FERC to facilitate market transparency in the market for sale or transportation of physical natural gas in interstate commerce; and (iii) significantly increase the penalties for violations of the Natural Gas Act, the Natural Gas Policy Act of 1978, and FERC rules, regulations or orders thereunder. As a result of the Energy Policy Act of 2005, the FERC has the authority to impose civil penalties for violations of these statutes and FERC rules, regulations and orders, up to $1 million per day per violation.

In May 2012, we requested FERC authorization for Steuben Gas Storage Company to abandon its tariff as part of its merger with Arlington Storage, and for Arlington Storage to thereafter charge marketed-based rates under its tariff for services at the Steuben facility. In October 2012, the FERC issued an order granting the requested authorizations. We consummated the abandonments and merger effective April 1, 2013. As a result, we charge market-based rates for storage service provided by our Thomas Corners, Seneca Lake and Steuben facilities and we provide wheeling services for all through facilities under one tariff (Arlington Storage’s tariff).

17

Our intrastate pipeline in New York (the East Pipeline) is subject to lightened regulation under NYPSC regulations and policies. Lightened regulation generally exempts us from NYPSC regulation applicable to the provision of retail service. CPE, as the owner and operator of the East Pipeline, remains subject to limited corporate (e.g., obtaining approval prior to any transfer of its ownership interests or the issuance of debt securities) and operational and safety (e.g., filing of vegetation management plan) regulation established and maintained by the NYPSC.

Our interstate natural gas storage operations are also subject to non-rate regulation by various state agencies. For example, the NYSDEC has jurisdiction over the underground storage of natural gas and well drilling, conversion and plugging in New York. The NYSDEC therefore regulates aspects of our Stagecoach, Thomas Corners, Seneca Lake and Steuben natural gas storage facilities.

Natural Gas Gathering

Natural gas gathering facilities are exempt from FERC jurisdiction under Section 1(b) of the Natural Gas Act. Although the FERC has not made formal determinations with respect to all of our facilities we consider to be gathering facilities, we believe that our natural gas pipelines meet the traditional tests that the FERC has used to determine that a pipeline is a gathering pipeline and is therefore not subject to FERC jurisdiction. The distinction between FERC-regulated transmission services and federally unregulated gathering services, however, has been the subject of substantial litigation, and the FERC determines whether facilities are gathering facilities on a case-by-case basis, so the classification and regulation of our gathering facilities is subject to change based on future determinations by the FERC, the courts or Congress. If the FERC were to consider the status of an individual facility and determine that the facility and/or services provided by it are not exempt from FERC regulation under the Natural Gas Act and the facility provides interstate service, the rates for, and terms and conditions of, services provided by such facility would be subject to regulation by the FERC under the Natural Gas Act or the Natural Gas Policy Act. Such regulation could decrease revenue, increase operating costs, and, depending upon the facility in question, could adversely affect our results of operations and cash flows. In addition, if any of our facilities were found to have provided services or otherwise operated in violation of the Natural Gas Act or the Natural Gas Policy Act, this could result in the imposition of civil penalties as well as a requirement to disgorge charges collected for such service in excess of the rate established by the FERC.

States may regulate gathering pipelines. State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances, requirements prohibiting undue discrimination, and in some instances complaint-based rate regulation. Our natural gas gathering operations may be subject to ratable take and common purchaser statutes in the states in which we operate. These statutes are designed to prohibit discrimination in favor of one producer over another producer or one source of supply over another source of supply, and they generally require our gathering pipelines to take natural gas without undue discrimination as to source of supply or producer. These statutes have the effect of restricting our right as an owner of gathering facilities to decide with whom we contract to purchase or transport natural gas.

The states in which we operate gathering systems have adopted a form of complaint-based regulation of natural gas gathering operations, which allows natural gas producers and shippers to file complaints with state regulators in an effort to resolve grievances relating to gathering access and rate discrimination. To date, these regulations have not had an adverse effect on our systems. We cannot predict whether such a complaint will be filed against us in the future, and failure to comply with state regulations can result in the imposition of administrative, civil and criminal remedies.

In Texas, we have filed with the Texas Railroad Commission (“TRCC”) to establish rates and terms of service for certain of our pipelines. Our assets in Texas include intrastate common carrier NGL pipelines subject to the regulation of the TRCC, which requires that our NGL pipelines file tariff publications that contain all the rules and regulations governing the rates and charges for services we perform. NGL pipeline rates may be limited to provide no more than a fair return on the aggregate value of the pipeline property used to render services.

NGL Storage

Our Bath storage terminal is subject primarily to state and local regulation. For example, the NYSDEC has jurisdiction over the underground storage of NGLs and well drilling, conversion and plugging in New York. Thus, the NYSDEC regulates aspects of the Bath facility.

18

We filed an application with the NYSDEC in October 2009 for an underground storage permit for our Watkins Glen NGL storage development project. The agency issued a Positive Declaration for the project in November 2010, determined in August 2011 that the Draft Supplemental Environmental Impact Statement we submitted for the project was complete, and held public hearings on the project in September and November 2011. In early 2012, based on concerns expressed by interested stakeholders and conversations with NYSDEC Staff, we informed the agency that we would reduce our environmental footprint and modified our brine pond design. In September 2012, we submitted to the NYSDEC final drawings and plans for our revised project design. Although we believe we have satisfied the administrative requirements necessary for the NYSDEC to issue the requested permits, we believe the agency’s determination is being delayed for political reasons unrelated to the project's design and environmental impact. Given the critical shortage of propane delivery options and storage infrastructure serving the Northeast and the record prices being paid by New York propane consumers in the 2013-2014 winter, we remain optimistic that state officials will recognize the importance of this critical energy infrastructure project and the NYSDEC will issue the permits this year. However, we cannot predict with certainty if and when the political challenges associated with the NYSDEC permitting process will dissipate.

Crude Oil Transportation

The transportation of crude oil by common carrier pipelines on an interstate basis is subject to regulation by the FERC under the Interstate Commerce Act (“ICA”), the Energy Policy Act of 1992, and the rules and regulations promulgated under those laws. FERC regulations require interstate common carrier petroleum pipelines to file with the FERC and publicly post tariffs stating their interstate transportation rates and terms and conditions of service. The ICA and FERC regulations also require that such rates be just and reasonable, and to be applied in a non-discriminatory manner and to not confer undue preference upon any shipper. The transportation of crude oil by common carrier pipelines on an intrastate is subject to regulation by state regulatory commissions. The basis for intrastate crude oil pipeline regulation, and the degree of regulatory oversight and scrutiny given to intrastate crude oil pipeline rates, varies from state to state. Intrastate common carriers must also offer service to all shippers requesting service on the same terms and under the same rates. Our crude oil pipelines in North Dakota are not common carrier pipelines and, therefore, are not subject to rate regulation by the FERC or any state regulatory commission.

Portions of our Arrow gathering system, which is located on the Fort Berthold Indian Reservation, are subject to regulation by the Mandan, Hidatsa & Arikara Nation. An entirely separate and distinct set of laws and regulations applies to operators and other parties within the boundaries of Native American reservations in the United States. Various federal agencies within the U.S. Department of the Interior, particularly the Bureau of Indian Affairs, the Office of Natural Resources Revenue and Bureau of Land Management (“BLM”), and the EPA, together with each Native American tribe, promulgate and enforce regulations pertaining to oil and gas operations on Native American reservations. These regulations include lease provisions, environmental standards, Tribal employment contractor preferences and numerous other matters.

Native American tribes are subject to various federal statutes and oversight by the Bureau of Indian Affairs and BLM. However, each Native American tribe is a sovereign nation and has the right to enact and enforce certain other laws and regulations entirely independent from federal, state and local statutes and regulations, as long as they do not supersede or conflict with such federal statutes. These tribal laws and regulations include various fees, taxes, requirements to employ Native American tribal members or use tribal owned service businesses and numerous other conditions that apply to lessees, operators and contractors conducting operations within the boundaries of a Native American reservation. Further, lessees and operators within a Native American reservation are often subject to the Native American tribal court system, unless there is a specific waiver of sovereign immunity by the Native American tribe allowing resolution of disputes between the Native American tribe and those lessees or operators to occur in federal or state court.

Therefore, we are subject to various laws and regulations pertaining to Native American oil and gas leases, fees, taxes and other burdens, obligations and issues unique to oil and gas operations within Native American reservations. One or more of these requirements, or delays in obtaining necessary approvals or permits pursuant to these regulations, may increase our costs of doing business on Native American tribal lands and have an impact on the economic viability of any well or project on those lands.

PHMSA is currently reviewing the adequacy of Bakken crude laboratory testing measures used to determine the packaging group selection for shipment of crude by rail. PHMSA's objective is to confirm that crude being offered for shipment by rail has been properly classified and characterized to ensure the safe transport to end users.  We, as the owner of a Bakken crude loading terminal, are providing input as this review process progresses through multiple agencies and organizations.

Environmental Matters

Our operations are subject to stringent federal, regional, state and local laws and regulations governing the discharge and emission of pollutants into the environment, environmental protection, or occupational health and safety. These laws and regulations may impose significant obligations on our operations, including the need to obtain permits to conduct regulated activities; restrict the types, quantities and concentration of materials that can be released into the environment; apply workplace health and safety standards for the benefit of employees; require remedial activities or corrective actions to mitigate pollution from former or current operations; and impose substantial liabilities on us for pollution resulting from our operations. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil and criminal penalties; the imposition of investigatory, remedial and corrective action obligations or the incurrence of capital expenditures; the occurrence of delays in the development of projects; and the issuance of injunctions restricting or prohibiting some or all of the activities in a particular area.

The following is a summary of the more significant existing federal environmental laws and regulations, each as amended from time to time, to which our business operations are subject:

• The Comprehensive Environmental Response, Compensation and Liability Act, a remedial statute that imposes strict liability on generators, transporters and arrangers of hazardous substances at sites where hazardous substance releases have occurred or are threatening to occur;

• The Resource Conservation and Recovery Act, which governs the treatment, storage and disposal of solid wastes, including hazardous wastes;

• The Clean Air Act, which restricts the emission of air pollutants from many sources and imposes various pre-construction, monitoring and reporting requirements;

• The Water Pollution Control Act, also known as the federal Clean Water Act, which regulates discharges of pollutants from facilities to state and federal waters;

• The Safe Drinking Water Act, which ensures the quality of the nation's public drinking water through adoption of drinking water standards and controlling the injection of substances into below-ground formations that may adversely affect drinking water sources;

• The National Environmental Policy Act, which requires federal agencies to evaluate major agency actions having the potential to significantly impact the environment and which may require the preparation of Environmental Assessments and more detailed Environmental Impact Statements that may be made available for public review and comment;

• The Endangered Species Act, which restricts activities that may affect federally identified endangered and threatened species or their habitats through the implementation of operating restrictions or a temporary, seasonal, or permanent ban in affected areas; and

• The Occupational Safety and Health Act, which establishes workplace standards for the protection of the health and safety of employees, including the implementation of hazard communications programs designed to inform employees about hazardous substances in the workplace, potential harmful effects of these substances, and appropriate control measures.

Certain of these environmental laws impose strict, joint and several liability for costs required to clean up and restore properties where pollutants have been released regardless of whom may have caused the harm or whether the activity was performed in compliance with all applicable laws. In the course of our operations, generated materials or wastes may have been spilled or released from properties owned or leased by us or on or under other locations where these materials or wastes have been taken for recycling or disposal. In addition, many of the properties owned or leased by us were previously operated by third parties whose management, disposal or release of materials and wastes was not under our control. Accordingly, we may be liable for the costs of cleaning up or remediating contamination arising out of our operations or as a result of activities by others who previously occupied or operated on properties now owned or leased by us. Private parties, including the owners of properties that we lease and facilities where our materials or wastes are taken for recycling or disposal, may also have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property or natural resource damages. We may not be able to recover some or any of these additional costs from insurance.

We have not received any notices that we have violated these environmental laws and regulations in any material respect and we have not otherwise incurred any material liability or capital expenditures thereunder. Future developments, such as stricter environmental laws or regulations, or more stringent enforcement of existing requirements could affect our operations. For instance, the EPA and other federal and state agencies are considering or have already commenced the study of potential adverse impacts that certain drilling methods (including hydraulic fracturing) may have on water quality and public health, with the U.S. Department of Energy having released a report recommending the implementation of a variety of measures to reduce the environmental impacts from shale-gas production. Similarly, Congress and several states have proposed or enacted legislation or regulations that are expected to make it more difficult or costly for exploration and production companies to

20

produce hydrocarbons. These initiatives, enactments and regulations could have an indirect adverse impact on us by decreasing demand for the services that we offer.

Employees

As of January 31, 2014, our subsidiary, US Salt, had 126 employees, 98 of which are members of the United Steel Workers union. We do not otherwise have employees, and we rely on CEQP under an omnibus agreement to provide us the corporate and other employees needed to carry out our operations. We believe that our relationship with our employees (including union labor) is satisfactory.

Item 1A. Risk Factors

Risks Inherent in Our Business

Our business depends on hydrocarbon supply and demand fundamentals, which can be adversely affected by numerous factors outside of our control.

Our success depends on the supply and demand for natural gas, NGLs and crude oil. The degree to which our business is impacted by changes in supply or demand varies. Our business can be negatively impacted by sustained downturns in supply and demand for one or more commodities, including reductions in our ability to renew contracts on favorable terms and to construct new infrastructure. For example, major factors that will impact natural gas demand domestically will be the realization of potential liquefied natural gas exports and demand growth within the power generation market, and a major factor impacting oil and gas supplies has been the significant growth in unconventional sources such as shale plays. In addition, the supply and demand for natural gas, NGLs and crude oil for our business will depend on many other factors outside of our control, some of which include:

• adverse changes in general global economic conditions. The level and speed of the recovery from the recent recession remains uncertain and could impact the supply and demand for natural gas and our future rate of growth in our business;

• adverse changes in domestic regulations that could impact the supply or demand for oil and gas;

• technological advancements that may drive further increases in production and reduction in costs of developing shale plays;

• competition from imported supplies and alternate fuels;

• increased commodity prices that could negatively impact demand for these products;

• increased costs to explore for, develop, produce, gather, process or transport commodities;

• adoption of various energy efficiency and conservation measures; and

• perceptions of customers on the availability and price volatility of our services, particularly customers’ perceptions on the volatility of commodity prices over the longer-term.

21

If volatility and seasonality in the oil and gas industry decrease, because of increased production capacity or otherwise, the demand for our services and the prices that we will be able to charge for those services may decline. In addition to volatility and seasonality, an extended period of high commodity prices would likely place upward pressure on the costs of associated expansion activities. An extended period of low commodity prices could adversely impact storage and transportation values for some period of time until market conditions adjust. These commodity price impacts could have a negative impact on our business, financial condition, and results of operations.

Our future growth may be limited if we do not complete growth projects or make acquisitions.

Our business strategy depends on our ability to complete growth projects and make acquisitions that increase cash generated from operations on a per unit basis. We may be unable to complete successful, accretive growth projects or acquisitions for any of the following reasons, among others:

• we fail to identify (or we are outbid for) attractive expansion or development projects or acquisition candidates that satisfy our economic and other criteria;

• we cannot raise financing for such projects or acquisitions on economically acceptable terms;

• we fail to secure adequate customer commitments to use the facilities to be developed, expanded or acquired; or

• we cannot obtain governmental approvals or other rights, licenses or consents needed to complete such projects or acquisitions on time or on budget, if at all. 

The development and construction of gathering, processing, storage and transportation facilities involves numerous regulatory, environmental, safety, political and legal uncertainties beyond our control and may require the expenditure of significant amounts of capital. When we undertake these projects, they may not be completed on schedule, at the budgeted cost or at all. Moreover, our revenues may not increase immediately upon the expenditure of funds on a particular growth project. For instance, if we build a new gathering system or transmission pipeline, the construction may occur over an extended period of time and we will not receive material increases in revenues until the project is placed in service. Accordingly, if we do pursue growth projects, we can provide no assurances that our efforts will provide a platform for additional growth for our company.

The growth projects and acquisitions we complete may not perform as anticipated.

Even if we complete acquisitions or growth projects that we believe will be strategic and accretive, such acquisitions and projects may nevertheless reduce our cash available for distribution due to the following factors, among others:

• mistaken assumptions about capacity, revenues, synergies, costs (including operating and administrative, capital, debt and equity costs), customer demand, growth potential, assumed liabilities and other factors;

• the failure to receive cash flows from a growth project or newly acquired asset due to delays in the commencement of operations for any reason;

• unforeseen operational issues or the realization of liabilities that were not known to us at the time the acquisition or growth project was completed; 

• the inability to attract new customers or retain acquired customers to the extent assumed in connection with an acquisition or growth project; 

• the failure to successfully integrate growth projects or acquired assets or businesses into our operations and/or the loss of key employees; or 

• the impact of regulatory, environmental, political and legal uncertainties that are beyond our control.

In particular, we may construct facilities to capture anticipated future growth in production and/or demand in a region in which such growth does not materialize. As a result, new facilities may not be able to attract enough throughput to achieve our expected investment return, which could adversely affect our business, financial condition, results of operations and ability to make distributions.

If we complete future growth projects or acquisitions, our capitalization and results of operations may change significantly, and you will not have the opportunity to evaluate the economic, financial and other relevant information that we will consider in determining the application of these funds and other resources. If any growth projects or acquisitions we ultimately complete are not accretive to our cash available for distribution, our ability to make distributions may be reduced.

22

Our failure to successfully and timely integrate acquired companies and assets into our organization could adversely affect our results of operation.

The success of the Crestwood Merger and our recent acquisitions (including our Arrow acquisition) will depend, in part, on our ability to realize the anticipated benefits and synergies from combining (i) the businesses of Legacy Inergy and Legacy Crestwood and (ii) our company and our acquisition targets. If our combined organization is unable to achieve these objectives, or is not able to achieve these objectives on a timely basis, the anticipated benefits of the Crestwood Merger and our acquisitions may not be realized fully or at all. Additional unanticipated costs may be incurred in the integration of the businesses. There can be no assurance that the elimination of certain duplicative costs, as well as the realization of other efficiencies related to the integration of the two businesses, will offset the incremental transaction-related costs over time. These integration difficulties could adversely affect the future results of the combined organization.

We rely upon third-party assets to operate our facilities, and we could be negatively impacted by circumstances beyond our control that temporarily or permanently interrupt the operation of such third-party assets.

Our operations depend on assets owned and controlled by third parties to operate effectively. For example, (i) certain of our “rich gas” gathering systems depend on interconnections and processing plants owned by third parties for us to move gas off our systems; (ii) our crude oil rail terminals depend on railroad companies to move our customers’ crude oil to market; and (iii) our natural gas storage facilities rely on third-party interconnections and pipelines to receive and deliver natural gas. Since we do not own or operate these third-party facilities, their continuing operation is outside of our control. If third-party facilities become unavailable or constrained, or other downstream facilities utilized to move our customers’ product to their end destination become unavailable, it could have a material adverse effect on our business, financial condition, results of operations, and ability to make distributions.

In addition, the rates charged by processing plants, pipelines and other facilities interconnected to our assets affect the utilization and value of our services. Significant changes in the rates charged by these third parties, or the rates charged by the third parties that own “downstream” assets required to move commodities to their final destinations, could have a material adverse effect on our business, financial condition, results of operations and ability to make distributions.

We depend on a limited number of customers for a substantial portion of our revenues.

We generate a substantial portion of our gathering revenue from a limited number of oil and gas producers. Within our G&P segment, the top five producers (including Antero in the Marcellus Shale and Quicksilver in the Barnett Shale) accounted for approximately 37% of our total consolidated revenues in 2013. Within our NGL and crude services segment, seven producers on our Arrow system in the Bakken Shale accounted for approximately 33% of our total consolidated revenues in 2013. We expect our gathering revenues to remain leveraged to a limited number of producers in 2014 as we continue to build out our gathering systems, particularly in the Marcellus, Bakken and PRB Niobrara.

Although we have obtained acreage dedications from many producer customers, most of our gathering contracts do not contain minimum volume requirements that would protect us against volumetric risks associated with lower-than-forecast volumes flowing through our systems. Our producer customers do not have contractual obligations to develop their properties in the areas covered by our acreage dedications, and they may determine that it is more attractive to direct their capital spending and resources to other areas. A decrease in producer capital spending and reserves in the areas covered by our acreage dedications with our significant gathering customers could result in reduced volumes serviced by us and a material decline in our revenue and cash flow.

Our gathering and processing operations depend, in part, on drilling and production decisions of others.

Our gathering and processing operations are dependent on the continued availability of natural gas and crude oil production. We have no control over the level of drilling activity in our areas of operation, the amount of reserves associated with wells connected to our systems, or the rate at which production from a well declines. Our gathering systems are connected to wells whose production will naturally decline over time, which means that our cash flows associated with these wells will decline over time. To maintain or increase throughput levels on our gathering systems and utilization rates at our natural gas processing plants, we must continually obtain new natural gas and crude oil supplies. Our ability to obtain additional sources of natural gas and crude oil primarily depends on the level of successful drilling activity near our systems, our ability to compete for volumes from successful new wells, and our ability to expand our system capacity as needed. If we are not able to obtain new supplies of natural gas and crude oil to replace the natural decline in volumes from existing wells, throughput on our gathering and processing facilities would decline, which could have a material adverse affect on our results of operations and distributable cash flow.

23

Although we have acreage dedications from customers that include certain producing and non-producing oil and gas properties, our customers are not contractually required to develop the reserves and or properties they have dedicated to us. We have no control over producers or their drilling and production decisions in our areas of operations, which are affected by, among other things, (i) the availability and cost of capital; (ii) prevailing and projected commodity prices; (iii) demand for natural gas, NGLs and crude oil, (iv) levels of reserves and geological considerations, (v) governmental regulations, including the availability of drilling permits and the regulation of hydraulic fracturing; and (vi) the availability of drilling rigs and other development services. Fluctuations in energy prices can also greatly affect the development of oil and gas reserves. Drilling and production activity generally decreases as commodity prices decrease, and sustained declines in commodity prices could lead to a material decrease in such activity. Because of these factors, even if oil and gas reserves are known to exist in areas served by our assets, producers may choose not to develop those reserves. Reductions in exploration or production activity in our areas of operations could lead to reduced utilization of our systems.

Estimates of oil and gas reserves depend on many assumptions that may turn out to be inaccurate, and future volumes on our gathering systems may be less than anticipated.

We normally do not obtain independent evaluations of natural gas or crude oil reserves connected to our gathering systems. We therefore do not have independent estimates of total reserves dedicated to our systems or the anticipated life of such reserves. It often takes producers longer periods of time to determine how to efficiently develop and produce hydrocarbons from unconventional shale plays than conventional basins, which can result in lower volumes becoming available as soon as expected in the shale plays in which we operate. If the total reserves or estimated life of the reserves connected to our gathering systems is less than anticipated and we are unable to secure additional sources of natural gas or crude oil, it could have a material adverse effect on our business, results of operations and financial condition.

We have limited experience in the crude oil gathering business.

We acquired the Arrow gathering system in November 2013, which serves customers producing crude oil and rich gas from the Bakken Shale formation. The Arrow system is the first crude oil and produced water gathering system that we have been required to build out and operate. Other operators of gathering systems in the Bakken have more experience in the construction, operation and maintenance of crude oil gathering systems than we do. Our lack of experience may hinder our ability to fully implement our business plan in a timely and cost-effective manner, which may adversely affect our results of operations and ability to make distributions.

Our industry is highly competitive, and increased competitive pressure could adversely affect our ability to execute our growth strategy.

We compete with other energy midstream enterprises, some of which are much larger and have significantly greater financial resources or operating experience, in our areas of operation. Our competitors may expand or construct infrastructure that creates additional competition for the services we provide to customers. Our ability to renew or replace existing contracts with our customers at rates sufficient to maintain current revenues and cash flow could be adversely affected by the activities of our competitors and our customers. All of these competitive pressures could have a material adverse effect on our business, results of operations, financial condition and ability to make distributions.

Our level of indebtedness could adversely affect our ability to raise additional capital to fund operations, limit our ability to react to changes in our business or industry, and place us at a competitive disadvantage.

We had approximately $1.9 billion of long-term debt outstanding as of December 31, 2013. Our inability to generate sufficient cash flow to satisfy debt obligations or to obtain alternative financing could materially and adversely affect our business, results of operations, financial condition and business prospects.

Our substantial debt could have important consequences to our unitholders. For example, it could:

• increase our vulnerability to general adverse economic and industry conditions;

• limit our ability to fund future capital expenditures and working capital, to engage in development activities, or to otherwise realize the value of our assets and opportunities fully because of the need to dedicate a substantial portion of our cash flow from operations to payments of interest and principal on our debt or to comply with any restrictive covenants or terms of our debt;

24

• result in an event of default if we fail to satisfy debt obligations or fail to comply with the financial and other restrictive covenants contained in the agreements governing our indebtedness, which event of default could result in all of our debt becoming immediately due and payable and could permit our lenders to foreclose on any of the collateral securing such debt;

• require a substantial portion of cash flow from operations to be dedicated to the payment of principal and interest on our indebtedness, therefore reducing our ability to use cash flow to fund operations, capital expenditures and future business opportunities;

• increase our borrowings;

• restrict us from making strategic acquisitions or causing us to make non-strategic divestitures;

• limit our flexibility in planning for, or reacting to, changes in our business or industry in which we operate, placing us at a competitive disadvantage compared to our peers who are less highly leveraged and who therefore may be able to take advantage of opportunities that our leverage prevents us from exploring; and

• impair our ability to obtain additional financing in the future.

Realization of any of these factors could adversely affect our financial condition, results of operations and cash flows.

Restrictions in our revolving credit facility could adversely affect our business, financial condition, results of operations and ability to make distributions.

We have a $1 billion revolving credit facility (expandable up to $1.25 billion) that matures in October 2018. Our revolving credit facility will be available to fund working capital and our growth projects, make acquisitions and for general partnership purposes.

Our revolving credit facility contains various covenants and restrictive provisions that will limit our ability to, among other things:

• incur additional debt;

• make distributions on or redeem or repurchase units;

• make certain investments and acquisitions; 

• incur or permit certain liens to exist; 

• enter into certain types of transactions with affiliates;

• merge, consolidate or amalgamate with another company; and 

• transfer or otherwise dispose of assets.

Furthermore, our revolving credit facility contains covenants requiring us to maintain certain financial ratios. For example, our revolving credit facility requires maintenance of a consolidated leverage ratio (as defined in our credit agreement) of not more than 5.00 to 1.00 and an interest coverage ratio (as defined in our credit agreement) of not less than 2.50 to 1.00. Borrowings under our revolving credit facility are secured by (i) pledges of the equity interests of, and guarantees by, substantially all of our existing and future restricted domestic subsidiaries, and (ii) liens on substantially all of our real property (outside of New York) and personal property.

The provisions of our credit agreement may affect our ability to obtain future financing and pursue attractive business opportunities and our flexibility in planning for, and reacting to, changes in business conditions. In addition, a failure to comply with the provisions of our revolving credit facility could result in an event of default, which could enable our lenders, subject to the terms and conditions of our revolving credit facility, to declare any outstanding principal of that debt, together with accrued interest, to be immediately due and payable. If the payment of any such debt is accelerated, our assets may be insufficient to repay such debt in full, and the holders of our common units could experience a partial or total loss of their investment.

A change of control could result in us facing substantial repayment obligations under our revolving credit facility.

Our credit agreement contains provisions relating to change of control of our general partner and our partnership. If these provisions are triggered, our outstanding bank indebtedness may become due. In such an event, there is no assurance that we would be able to pay the indebtedness, in which case the lenders under our revolving credit facility would have the right to

25

foreclose on our assets, which would have a material adverse effect on us. There is no restriction on the ability of our general partner or its parent companies to enter into a transaction which would trigger the change of control provisions.

Our ability to make cash distributions may be diminished, and our financial leverage could increase, if we are not able to obtain needed capital or financing on satisfactory terms.

Historically, we have used cash flow from operations, borrowings under our revolving credit facility and issuances of debt and equity to fund our capital program, working capital needs and acquisitions. Our capital program may require additional financing above the level of cash generated by our operations to fund our growth. If our cash flow from operations decreases as a result of lower throughput volumes on our systems or otherwise, our ability to expend the capital necessary to expand our business or increase our future cash distributions may be limited. If our cash flow from operations is insufficient to satisfy our financing needs, we cannot be certain that additional financing will be available to us on acceptable terms, if at all. Our ability to obtain bank financing or to access the capital markets for future equity or debt offerings may be limited by our financial condition or general economic conditions at the time of any such financing or offering. Even if we are successful in obtaining the necessary funds, the terms of such financings could have a material adverse effect on our business, results of operation, financial condition and ability to make cash distributions to our unitholders. Further, incurring additional debt may significantly increase our interest expense and financial leverage and issuing additional limited partner interests may result in significant unitholder dilution and would increase the aggregate amount of cash required to maintain the cash distribution rate which could materially decrease our ability to pay distributions. If additional capital resources are unavailable, we may curtail our activities or be forced to sell some of our assets on an untimely or unfavorable basis.

Debt we incur in the future may limit our flexibility to obtain financing and to pursue other business opportunities.

Our future level of debt could have important consequences to us, including the following:

• our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or such financing may not be available on favorable terms, if at all; 

• our funds available for operations, future business opportunities and distributions to common unitholders will be reduced by that portion of our cash flow required to make interest payments on our debt; 

• we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and

• our flexibility in responding to changing business and economic conditions may be limited.

Our ability to service our debt will depend upon, among other things, our future financial and operating performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service any future indebtedness, we will be forced to take actions such as reducing distributions, reducing or delaying our business activities, acquisitions, investments or capital expenditures, selling assets or seeking additional equity capital. We may not be able to effect any of these actions on satisfactory terms or at all.

Increases in interest rates could adversely impact our unit price, ability to issue equity or incur debt for acquisitions or other purposes, and ability to make payments on our debt obligations.

Interest rates may increase in the future. As a result, interest rates on future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly. Therefore, changes in interest rates either positive or negative, may affect the yield requirements of investors who invest in our units, and a rising interest rate environment could have an adverse impact on our unit price and our ability to issue equity or incur debt for acquisitions or other purposes and to make payments on our debt obligations.

The loss of key personnel could adversely affect our ability to operate.

Our success is dependent upon the efforts of our senior management team, as well as on our ability to attract and retain both executives and employees for our field operations. Our senior executives have significant experience in the oil and gas industry and have developed strong relationships with a broad range of industry participants. The loss of any of these executives, or the loss of key field employees operating in competitive markets like the Bakken Shale and the Marcellus Shale, could prevent us from implementing our business strategy and could have a material adverse effect on our customer relationships, results of operations and ability to make distributions.

26

We operate in the PRB Niobrara through joint ventures that may limit our operational flexibility.

Our operations in the PRB Niobrara are conducted through joint venture arrangements (including the Jackalope and PRBIC joint ventures), and we may enter additional joint ventures in the future. In a joint venture arrangement, we could have less operational flexibility, as actions must be taken in accordance with the applicable governing provisions of the joint venture. In certain cases, we:

• could have limited ability to influence or control certain day to day activities affecting the operations;

• could have limited control on the amount of capital expenditures that we are required to fund with respect to these operations;

• could be dependent on third parties to fund their required share of capital expenditures;

• may be subject to restrictions or limitations on our ability to sell or transfer our interests in the jointly owned assets; and

• may be forced to offer rights of participation to other joint venture participants in certain areas of mutual interest.

In addition, our joint venture participants may have obligations that are important to the success of the joint venture, such as the obligation to pay substantial carried costs pertaining to the joint venture and to pay their share of capital and other costs of the joint venture. The performance and ability of the third parties to satisfy their obligations under joint venture arrangements is outside of our control. If these parties do not satisfy their obligations, our business may be adversely affected. Our joint venture partners may be in a position to take actions contrary to our instructions or requests or contrary to our policies or objectives, and disputes between us and our joint venture partners may result in delays, litigation or operational impasses. The risks described above or the failure to continue our joint ventures or to resolve disagreements with our joint venture partners could adversely affect our ability to conduct business that is the subject of a joint venture, which could in turn negatively affect our financial condition and results of operations.

We may not be able to renew or replace expiring contracts.

Our primary exposure to market risk occurs at the time our existing contracts expire and are subject to renegotiation and renewal. As of December 31, 2013, the weighted average remaining term of (i) our existing portfolio of natural gas storage and transportation contracts is approximately four years, (ii) our existing portfolio of natural gas gathering contracts is approximately 11 years, and (iii) our existing portfolio of crude oil gathering contracts is approximately five years. The extension or replacement of existing contracts depends on a number of factors beyond our control, including:

• the macroeconomic factors affecting natural gas, NGL and crude economics for our current and potential customers;

• the level of existing and new competition to provide services to our markets;

• the balance of supply and demand, on a short-term, seasonal and long-term basis, in our markets;

• the extent to which the customers in our markets are willing to contract on a long-term basis; and

• the effects of federal, state or local regulations on the contracting practices of our customers.

Any failure to extend or replace a significant portion of our existing contracts, or extending or replacing them at unfavorable or lower rates, could have a material adverse effect on our business, financial condition, results of operations and ability to make distributions.

The fees we charge to customers under our contracts may not escalate sufficiently to cover our cost increases, and those contracts may be suspended in some circumstances.

Our costs may increase at a rate greater than the rate that the fees we charge to third parties increase pursuant to our contracts with them. In addition, some third parties’ obligations under their agreements with us may be permanently or temporarily reduced upon the occurrence of certain events, some of which are beyond our control, including force majeure events wherein the supply of natural gas or crude oil is curtailed or cut off. Force majeure events generally include, without limitation, revolutions, wars, acts of enemies, embargoes, import or export restrictions, strikes, lockouts, fires, storms, floods, acts of God, explosions, mechanical or physical failures of our equipment or facilities or those of third parties. If our escalation of fees is insufficient to cover increased costs or if any third party suspends or terminates its contracts with us, our business, financial condition, results of operations and ability to make distributions could be materially adversely affected.

27

Our operations are subject to extensive regulation, and regulatory measures adopted by regulatory authorities could have a material adverse effect on our business, financial condition and results of operations.

Our operations are subject to extensive regulation by federal, state and local regulatory authorities. For example, because we transport natural gas in interstate commerce and we store natural gas that is transported in interstate commerce, our natural gas storage and transportation facilities are subject to comprehensive regulation by the FERC under the Natural Gas Act. Federal regulation under the Natural Gas Act extends to such matters as:

• rates, operating terms and conditions of service;

• the form of tariffs governing service;

• the types of services we may offer to our customers; 

• the certification and construction of new, or the expansion of existing, facilities;

• the acquisition, extension, disposition or abandonment of facilities; 

• contracts for service between storage and transportation providers and their customers; 

• creditworthiness and credit support requirements; 

• the maintenance of accounts and records;

• relationships among affiliated companies involved in certain aspects of the natural gas business;

• the initiation and discontinuation of services; and 

• various other matters.

Natural gas companies may not charge rates that, upon review by FERC, are found to be unjust and unreasonable or unduly discriminatory. Existing interstate transportation and storage rates may be challenged by complaint and are subject to prospective change by FERC. Additionally, rate increases proposed by a regulated pipeline or storage provider may be challenged and such increases may ultimately be rejected by FERC. We currently hold authority from FERC to charge and collect (i) market-based rates for interstate storage services provided at the Stagecoach, Thomas Corners, Seneca Lake and Steuben facilities and (ii) negotiated rates for interstate transportation services provided by our North-South Facilities and our MARC I Pipeline. FERC's “market-based rate” policy allows regulated entities to charge rates different from, and in some cases, less than, those which would be permitted under traditional cost-of-service regulation. Among the sorts of changes in circumstances that could raise market power concerns would be an expansion of capacity, acquisitions or other changes in market dynamics. There can be no guarantee that we will be allowed to continue to operate under such rate structures for the remainder of those assets' operating lives. Any successful challenge against rates charged for our storage and transportation services, or our loss of market-based rate authority or negotiated rate authority, could have a material adverse effect on our business, financial condition, results of operations and ability to make distributions. Our market-based rate authority for our natural gas storage facilities may be subject to review and possible revocation if FERC determines that we have the ability to exercise market power in our market area. If we were to lose our ability to charge market-based rates, we would be required to file rates based on our cost of providing service, including a reasonable rate of return. Cost-of-service rates may be lower than our current market-based rates.

There can be no assurance that FERC will continue to pursue its approach of pro-competitive policies as it considers matters such as pipeline rates and rules and policies that may affect rights of access to natural gas transportation capacity and transportation and storage facilities. Failure to comply with applicable regulations under the Natural Gas Act, the Natural Gas Policy Act of 1978, the Pipeline Safety Act of 1968 and certain other laws, and with implementing regulations associated with these laws, could result in the imposition of administrative and criminal remedies and civil penalties of up to $1,000,000 per day, per violation.

A change in the jurisdictional characterization of our gathering assets may result in increased regulation, which could cause our revenues to decline and operating expenses to increase.

Our natural gas and crude oil gathering operations are generally exempt from the jurisdiction and regulation of the FERC, except for certain anti-market manipulation provisions. FERC regulation nonetheless affects our businesses and the markets for products derived from our gathering businesses. The FERC’s policies and practices across the range of its oil and gas regulatory activities, including, for example, its policies on open access transportation, rate making, capacity release and market center promotion, indirectly affect intrastate markets. In recent years, the FERC has pursued pro-competitive policies in its regulation of interstate oil and natural gas pipelines. However, we have no assurance that the FERC will continue this approach as it considers matters such as pipeline rates and rules and policies that may affect rights of access to oil and natural gas transportation capacity. In addition, the distinction between FERC-regulated transmission services and federally unregulated gathering services has regularly been the subject of substantial, on-going litigation. Consequently, the classification and regulation of some of our pipelines could change based on future determinations by the FERC, the courts or Congress. If

28

our gathering operations become subject to FERC jurisdiction, the result may adversely affect the rates we are able to charge and the services we currently provide, and may include the potential for a termination of certain gathering agreements.

State and municipal regulations also impact our business. Common purchaser statutes generally require gatherers to gather or provide services without undue discrimination as to source of supply or producer; as a result, these statutes restrict our right to decide whose production we gather or transport. Federal law leaves any economic regulation of natural gas gathering to the states. The states in which we currently operate have adopted complaint-based regulation of gathering activities, which allows oil and gas producers and shippers to file complaints with state regulators in an effort to resolve access and rate grievances. Other state and municipal regulations may not directly regulate our gathering business, but may nonetheless affect the availability of natural gas for purchase, processing and sale, including state regulation of production rates and maximum daily production allowable from gas wells. While our gathering lines currently are subject to limited state regulation, there is a risk that state laws will be changed, which may give producers a stronger basis to challenge the rates, terms and conditions of its gathering lines.

Our operations are subject to compliance with environmental and operational safety laws and regulations that may expose us to significant costs and liabilities.

Our operations are subject to stringent federal, regional, state and local laws and regulations governing health and safety aspects of our operations, the discharge of materials into the environment or otherwise relating to environmental protection. Such environmental laws and regulations impose numerous obligations that are applicable to our operations, including the acquisition of permits to conduct regulated activities, the incurrence of capital expenditures to comply with applicable legal requirements, the application of specific health and safety criteria addressing worker protections and the imposition of restrictions on the generation, handling, treatment, storage, disposal and transportation of materials and wastes. Failure to comply with such environmental laws and regulations can result in the assessment of substantial administrative, civil and criminal penalties, the imposition of remedial liabilities and the issuance of injunctions restricting or prohibiting some or all of our activities. Certain environmental laws impose strict, joint and several liability for costs required to clean up and restore sites where materials or wastes have been disposed or otherwise released. In the course of our operations, generated materials or wastes may have been spilled or released from properties owned or leased by us or on or under other locations where these materials or wastes have been taken for recycling or disposal.

It is also possible that adoption of stricter environmental laws and regulations or more stringent interpretation of existing environmental laws and regulations in the future could result in additional costs or liabilities to us as well as the industry in general or otherwise adversely affect demand for our services and salt products. It is also possible that adoption of stricter environmental laws and regulations or more stringent interpretation of existing environmental laws and regulations in the future could result in additional costs or liabilities to us or our customers and also adversely affect demand for the natural gas, NGLs, crude oil or salt products.

Climate change legislation or regulations restricting emissions of greenhouse gases could result in increased operating and capital costs and reduced demand for our services.

In December 2009, the EPA determined that emissions of carbon dioxide, methane and other greenhouse gases (GHGs) present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth's atmosphere and other climatic changes. Based on these findings, the EPA has begun adopting and implementing regulations to restrict emissions of GHGs under existing provisions of the federal Clean Air Act. The EPA has adopted two sets of rules regulating GHG emissions under the Clean Air Act, one of which requires a reduction in emissions of GHGs from motor vehicles and the other of which regulates emissions of GHGs from certain large stationary sources, effective January 2, 2011, which could require greenhouse emission controls for those sources. The EPA has also adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources on an annual basis, beginning in 2011 for emissions occurring after January 1, 2010, as well as certain onshore oil and natural gas production, processing, transmission, storage and distribution facilities on an annual basis, beginning in 2012 for emissions occurring in 2011.

In addition, the U.S. Congress has from time to time considered adopting legislation to reduce emissions of GHGs, and almost one-half of the states have already taken legal measures to reduce emissions of GHGs primarily through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. Most of these cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major producers of fuels, such as refineries and gas processing plants, to acquire and surrender emission allowances. The number of allowances available for purchase is reduced each year in an effort to achieve the overall GHG emission reduction goal.

29

The adoption of legislation or regulatory programs to reduce emissions of GHGs could require us to incur increased operating costs, such as costs to purchase and operate emissions control systems, to acquire emissions allowances or comply with new regulatory or reporting requirements. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand for, the oil and natural gas that is produced, which may decrease demand for our midstream services. Consequently, legislation and regulatory programs to reduce emissions of GHGs could have an adverse effect on our business, financial condition and results of operations.

We may incur higher costs as a result of pipeline integrity management program testing and additional safety legislation.

The DOT requires pipeline operators to develop integrity management programs for pipelines located where a leak or rupture could harm “high consequence areas.” The regulations require operators like us to:

• perform ongoing assessments of pipeline integrity;

• identify and characterize applicable threats to pipeline segments that could impact a high consequence area;

• maintain processes for data collection, integration and analysis;

• repair and remediate pipelines as necessary; and

• implement preventive and mitigating actions.

We estimate that the total future costs to complete the testing required by existing DOT regulations will not have a material impact to our results. This estimate does not include the costs, if any, for repair, remediation, preventative or mitigating actions that may be determined to be necessary as a result of the testing program itself.

Moreover, the Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 was enacted by Congress in December 2011 and signed into law by the President on January 3, 2012. In addition to reauthorizing federal pipeline safety programs through 2015, this legislation adopts additional safety requirements and reforms and increases penalties for safety violations. The PHMSA has also published an advanced notice of proposed rule making to solicit comments on the need for changes to its safety regulations, including whether to revise the integrity management requirements and add new regulations governing the safety of gathering lines. Such legislative and regulatory changes could have a material effect on our operations through more stringent and comprehensive safety regulations and higher penalties for the violation of those regulations.

Our business involves many hazards and risks, some of which may not be fully covered by insurance.

Our operations are subject to many risks inherent in gathering, processing, storage and transportation segments of the energy midstream industry, such as:

• damage to pipelines and plants, related equipment and surrounding properties caused by natural disasters and acts of terrorism;

• subsidence of the geological structures where we store natural gas or NGLs, or storage cavern collapses;

• operator error;

• inadvertent damage from construction, farm and utility equipment;

• leaks, migrations or losses of natural gas, NGLs or crude oil;

• fires and explosions;

• cyber intrusions; and

• other hazards that could also result in personal injury, loss of life, pollution (including environmental pollution) or suspension of operations.

These risks could result in substantial losses due to breaches of contractual commitments, personal injury and/or loss of life, damage to and destruction of property and equipment and pollution or other environmental damage. These risks may also result in curtailment or suspension of our operations. A natural disaster or other hazard affecting the areas in which we operate could have a material adverse effect on our operations. We are not fully insured against all risks inherent in our business. For example, we do not have any property insurance on any of our underground pipeline systems that would cover damage to the pipelines. We are also not insured against all environmental accidents that might occur, some of which may result in toxic tort claims. If a significant accident or event occurs for which we are not fully insured, it could result in a material adverse effect on our business, financial condition, results of operations and ability to make distributions.

We may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for certain of our insurance policies may substantially increase. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. Additionally, we may be unable to recover from prior owners of our assets, pursuant to our indemnification rights, for potential environmental liabilities.

30

Although we maintain insurance policies with insurers in such amounts and with such coverages and deductibles as we believe are reasonable and prudent, our insurance may not be adequate to protect us from all material expenses related to potential future claims for personal injury and property damage.

We also share insurance coverage with Crestwood Equity, for which we reimburse Crestwood Equity pursuant to the terms of the omnibus agreement. To the extent Crestwood Equity experiences covered losses under the insurance policies, the limit of our coverage for potential losses may be decreased.

We do not own all of the land on which our pipelines and facilities are located, which could disrupt our operations.

We do not own all of the land on which our pipelines and facilities (particularly our gathering and process facilities) have been constructed, which subjects us to the possibility of more onerous terms or increased costs to obtain and maintain valid easements and rights-of-way. We obtain standard easement rights to construct and operate its pipelines on land owned by third parties, and our rights frequently revert back to the landowner after we stop using the easement for its specified purpose.

Therefore, these easements exist for varying periods of time. Our loss of easement rights could have a material adverse effect on our ability to operate our business, thereby resulting in a material reduction in our revenue, earnings and ability to make distributions.

Risks Inherent in an Investment in Us

We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses to enable us to pay quarterly distributions to our common unitholders.

We may not have sufficient cash each quarter to continue payments consistent with the full amount of our initial quarterly distribution of $0.37 per unit, or $1.48 per unit per year. The amount of cash we can distribute on our common units principally depends upon the amount of cash we generate from our operations and payments of fees and expenses. Before we pay any distributions on our common units, we will establish reserves and pay fees and expenses, including reimbursements to our general partner and its affiliates, including Crestwood Equity, for all expenses they incur and payments they make on our behalf. These costs will reduce the amount of cash available to pay distributions to our common unitholders.

The amount of cash we can distribute on our common units will fluctuate from quarter to quarter based on, among other things:

• the rates we charge for storage and transportation services and the amount of services our customers purchase from us, which will be affected by, among other things, the overall balance between the supply of and demand for natural gas, governmental regulation of our rates and services, and our ability to obtain permits for growth projects;

• force majeure events that damage our or third-party pipelines, facilities, related equipment and surrounding properties;

•prevailing economic and market conditions;

•governmental regulation, including changes in governmental regulation in our industry;

•changes in tax laws;

•the level of competition from other midstream companies;

•the level of our operating and maintenance and general administrative costs;

•the level of capital expenditures we make;

•our ability to make borrowings under our revolving credit facility; and

•the cost of acquisitions.

In addition, the actual amount of cash we will have available for distribution will depend on other factors, some of which are beyond our control, including: the level and timing of capital expenditures we make; the cost of acquisitions; our debt service requirements and other liabilities; fluctuations in our working capital needs; our ability to borrow funds and access capital markets; restrictions contained in our debt agreements; and the amount of cash reserves established by our general partner.

Our partnership agreement requires that we distribute all of our available cash, which could limit our ability to grow and make acquisitions.

We expect that we will distribute all of our available cash to our common unitholders and will rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. As a result, to the extent we are unable to finance growth externally, our cash distribution policy will significantly impair our ability to grow.

31

In addition, because we distribute all of our available cash, our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement, or in our revolving credit facility, on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may impact the available cash that we have to distribute to our common unitholders.

We may issue additional units without common unitholder approval, which would dilute existing common unitholder ownership interests.

Our partnership agreement does not limit the number of additional limited partner interests we may issue at any time without the approval of our existing common unitholders. The issuance of additional common units or other equity interests of equal or senior rank will have the following effects:

• our existing common unitholders' proportionate ownership interest in us will decrease; 

•the amount of cash available for distribution on each common unit may decrease; 

•the ratio of taxable income to distributions may increase; 

•the relative voting strength of each previously outstanding common unit may be diminished; and 

•the market price of the common units may decline.

Holders of our common units have limited voting rights and are not entitled to elect our general partner or its directors, which could reduce the price at which our common units will trade.

Unlike the holders of common stock in a corporation, our common unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management's decisions regarding our business. Our common unitholders will have no right on an annual or ongoing basis to elect our general partner or its board of directors. The board of directors of our general partner, including the independent directors, is chosen entirely by Crestwood Equity, as a result of it owning our general partner, and not by our common unitholders. Unlike publicly traded corporations, we will not conduct annual meetings of our common unitholders to elect directors or conduct other matters routinely conducted at annual meetings of stockholders of corporations. As a result of these limitations, the price at which the common units will trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

Common unitholders may have liability to repay distributions and in certain circumstances may be personally liable for the obligations of the partnership.

Under certain circumstances, common unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act (the "Delaware Act"), we may not make a distribution to our common unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. A purchaser of units who becomes a limited partner is liable for the obligations of the transferring limited partner to make contributions to the partnership that are known to the purchaser of units at the time it became a limited partner and for unknown obligations if the liabilities could be determined from the partnership agreement. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

It may be determined that the right, or the exercise of the right by the limited partners as a group, to (i) remove or replace our general partner, (ii) approve some amendments to our partnership agreement or (iii) take other action under our partnership agreement constitutes “participation in the control” of our business. A limited partner that participates in the control of our business within the meaning of the Delaware Act may be held personally liable for our obligations under the laws of Delaware to the same extent as our general partner. This liability would extend to persons who transact business with us under the reasonable belief that the limited partner is a general partner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner.

32

The amount of cash we have available for distribution to common unitholders depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.

The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from reserves and working capital or other borrowings, and not solely on profitability, which will be affected by non-cash items. As a result, we may pay cash distributions during periods when we record net losses for financial accounting purposes and may not pay cash distributions during periods when we record net income.

Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Our partnership agreement restricts unitholders' voting rights by providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our general partner and its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our general partner, cannot vote on any matter.

Reimbursements due to our general partner and its affiliates for services provided to us or on our behalf will reduce cash available for distribution to our common unitholders. The amount and timing of such reimbursements will be determined by our general partner.

Prior to making any distribution on our common units, we will reimburse our general partner and its affiliates, including Crestwood Equity, for all administrative costs and other expenses they incur and payments they make on our behalf pursuant to the omnibus agreement. Under the omnibus agreement, we will reimburse our general partner and its affiliates for all expenses incurred on our behalf, including administrative costs, such as compensation expense for those persons who provide services necessary to run our business, and insurance expenses. As of December 31, 2013, we reimbursed our general partner and its affiliates approximately $21.9 million in fiscal year 2013 (including $16.9 million in reimbursements of direct personnel related expenses). Neither our partnership agreement nor the omnibus agreement limits the amount of expenses for which our general partner and its affiliates may be reimbursed. Our partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us. The reimbursement of expenses and payment of fees, if any, to our general partner and its affiliates will reduce the amount of available cash to pay cash distributions to our common unitholders.

The credit and risk profile of our general partner and its owner, Crestwood Equity, could adversely affect our credit ratings and risk profile, which could increase our borrowing costs or hinder our ability to raise capital.

The credit and business risk profiles of our general partner and Crestwood Equity may be factors considered in credit evaluations of us. This is because our general partner, which is owned by Crestwood Equity, controls our business activities, including our cash distribution policy and growth strategy. Any adverse change in Crestwood Equity's financial condition, including the degree of its financial leverage and its dependence on cash flow from us to service its debt, may adversely affect our credit ratings and risk profile.

If we were to seek a credit rating in the future, our credit rating may be adversely affected by the leverage of our general partner or Crestwood Equity, as credit rating agencies such as Standard & Poor's Ratings Services and Moody's Investors Service may consider the leverage and credit profile of Crestwood Equity and its affiliates because of their ownership interest in and control of us. Any adverse effect on our credit rating would increase our cost of borrowing or hinder our ability to raise financing in the capital markets, which would impair our ability to grow our business and make distributions to common unitholders.

Our general partner has a limited call right that may require unitholders to sell their common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80% of our outstanding units, our general partner will have the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (i) the average of the daily closing prices per limited partner interest of the class purchased for the 20 consecutive trading days immediately prior to the date three days before the date our general partner first mails notice of its election to purchase those limited partner interests, and (ii) the highest price paid by our general partner or any of its affiliates for any limited partner interests of the class purchased during the 90-day period preceding the date that the notice is mailed. As a result, our unitholders may be required to sell their common units at an undesirable time or price and may not receive any return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their common units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right. There

33

is no restriction in our partnership agreement that prevents our general partner from issuing additional common units and exercising its call right. If our general partner exercised its limited call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Exchange Act. As of December 31, 2013 Crestwood Equity and its affiliates own, directly or indirectly, an aggregate of approximately 4% of our common units.

Crestwood Holdings and its affiliates may sell common units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units.

As of December 31, 2013, Crestwood Holdings and its affiliates beneficially held an aggregate of 28,995,823 common units. The sale of any or all of these units in the public or private markets could have an adverse impact on the price of the common units or on any trading market on which the common units are traded.

Risks Inherent in Our Structure and Relationship with Crestwood Equity

Crestwood Equity controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner and its affiliates, including Crestwood Equity, have conflicts of interest with us and limited duties, and they may favor their own interests to the detriment of us and our common unitholders.

Crestwood Equity owns and controls our general partner and appoints all of the directors of our general partner. Although our general partner has a duty to manage our partnership in a manner it believes is in our best interests, the executive officers and directors of our general partner have a fiduciary duty to manage our general partner in a manner beneficial to Crestwood Equity. Therefore, conflicts of interest may arise between our general partner and its affiliates, including Crestwood Equity, on the one hand, and us and our common unitholders, on the other hand. In resolving these conflicts of interest, our general partner may favor its own interests and the interests of its affiliates over the interests of our common unitholders.

Crestwood Equity and other affiliates of our general partner may compete with us and are not obligated to offer us the opportunity to acquire additional assets or businesses, which could limit our ability to grow and could adversely affect our results of operations and cash available for distribution to our unitholders.

Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. Affiliates of our general partner, including Crestwood Equity, are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us. Crestwood Equity currently holds interests in, and may make investments in and purchases of, entities that acquire, own and operate crude oil, natural gas and NGL midstream assets. In addition, Crestwood Equity is entitled under the omnibus agreement to review and has the first option on any third-party acquisition opportunities presented to us or to Crestwood Equity and is under no obligation to make acquisition opportunities available to us. These investments and acquisitions may include entities or assets that we would have been interested in acquiring. Therefore, Crestwood Equity may compete with us for investment opportunities, and may own interests in entities that compete with us.

Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our general partner or any of its affiliates, including its executive officers and directors and Crestwood Equity. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of us and our common unitholders.

Our general partner intends to limit its liability regarding our contractual and other obligations.

Our general partner intends to limit its liability under our contractual and other obligations so that the counterparties to such arrangements have recourse only against our assets and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement provides that any action taken by our general partner to limit its liability is not a breach of our general partner's duties, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our common unitholders.

34

Our partnership agreement restricts the remedies available to our common unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty.

Our partnership agreement contains provisions that restrict the remedies available to our common unitholders for actions taken by our general partner that might otherwise constitute breaches of duty under state law with respect to fiduciary duties. For example, our partnership agreement provides that:

• whenever our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) makes a determination or takes, or declines to take, any other action in their respective capacities, our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee), as applicable, is required to make such determination, or take or decline to take such other action, in good faith, and is not subject to any higher standard imposed by our partnership agreement, Delaware law or any other law, rule or regulation, or at equity; 

• a determination, other action or failure to act by our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) is deemed to be in good faith unless our general partner, the board of directors of our general partner or any committee thereof believed such determination, other action or failure to act was not in the best interests of the partnership; 

• our general partner does not have any liability to us or our common unitholders for decisions made in its capacity as a general partner so long as it acted in good faith; and 

• our general partner and its officers and directors are not be liable for monetary damages to us or our limited partners for any acts or omissions unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that our general partner or those other persons acted in bad faith or, in the case of a criminal matter, acted with knowledge that the conduct was unlawful. 

Whenever a conflict arises between our general partner or its affiliates, on the one hand, and us and our limited partners, on the other hand, the resolution or course of action in respect of such conflict of interest shall be permitted and deemed approved by all our limited partners and shall not constitute a breach of our partnership agreement, of any agreement contemplated thereby or of any duty, if the resolution or course of action in respect of such conflict of interest is (i) approved by the conflicts committee of the board of directors of our general partner, although our general partner is not obligated to seek such approval; or (ii) approved by the vote of a majority of the outstanding common units, excluding any common units owned by our general partner or its affiliates.

In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our general partner must be made in good faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee then it will be presumed that, in making its decision, taking any action or failing to act, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

Unlike many other master limited partnerships, which require at least two independent members of the conflicts committee, our partnership agreement provides that a conflicts committee may be comprised of one or more directors. If we establish a conflicts committee with only one director, your interests may not be as well served as if we had a conflicts committee comprised of at least two independent directors. A single member conflicts committee would not have the benefit of discussion with and input from other independent directors.

Our partnership agreement limits our general partner's duties to holders of our common units.

Our partnership agreement contains provisions that modify and reduce the standards to which our general partner would otherwise be held by state law with respect to fiduciary duties. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner, or otherwise free of contractual or fiduciary duties to us and our common unitholders. This entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our general partner may make in its individual capacity include:

• how to allocate business opportunities among us and its affiliates; 

•whether to exercise its limited call right; 

•how to exercise its voting rights with respect to any common units it owns; 

•whether to exercise its registration rights; and

•whether or not to consent to any merger or consolidation of us or amendment to the partnership agreement.

35

By purchasing a common unit, a common unitholder is treated as having consented to the provisions in the partnership agreement, including the provisions discussed above. 

Crestwood Equity may elect to cause us to issue common units to it in connection with a resetting of the quarterly distribution related to its IDRs, without the approval of the conflicts committee of the board of directors of our general partner or the holders of our common units. This election could result in lower distributions to our common unitholders.

Crestwood Equity has the right to reset, at a higher level, the quarterly distribution based on our cash distributions at the time of the exercise of the reset election. Following a reset election, the quarterly distribution will be reset to an amount equal to the cash distribution amount per common unit for the quarter immediately preceding the reset election (which amount we refer to as the reset quarterly distribution).

If Crestwood Equity elects to reset the quarterly distribution, it will be entitled to receive a number of newly issued common units. The number of common units to be issued to Crestwood Equity will equal the number of common units that would have entitled the holder to the quarterly cash distribution in the prior quarter equal to the distribution to Crestwood Equity on the IDRs in such prior quarter. It is possible that Crestwood Equity could exercise this reset election at a time when it is experiencing, or expects to experience, declines in the cash distributions it receives related to its IDRs and may, therefore, desire to be issued common units rather than retain the right to receive incentive distributions based on the quarterly distribution. As a result, a reset election may cause our common unitholders to experience a reduction in the amount of cash distributions that our common unitholders would have otherwise received had we not issued new common units to Crestwood Equity in connection with resetting the quarterly distribution.

Even if holders of our common units are dissatisfied, they cannot currently remove our general partner without its consent.

If our common unitholders are dissatisfied with the performance of our general partner, they have limited ability to remove our general partner. The vote of the holders of at least two-thirds of all our outstanding limited partnership interests voting together as a class is required to remove our general partner. As of December 31, 2013, Crestwood Equity and its affiliates currently own, directly or indirectly, an aggregate of 4% of our common units.

Our general partner interest, our IDRs and control of our general partner may be transferred without common unitholder consent.

Our partnership agreement provides that, at any time, our general partner may transfer all or any of its general partner interest or common units to another person without the consent of our common unitholders. If the sole member of our general partner transfers its membership interest in our general partner to a third party, the third party would be in a position to replace the board of directors and executive officers of our general partner with its designees and thereby exert significant control over the decisions taken by the board of directors and executive officers of our general partner. This effectively permits a “change of control” without the vote or consent of the common unitholders. Our partnership agreement also provides that the holder of the IDRs may transfer those interests to a third party at any time without the consent of our common unitholders. Crestwood Equity indirectly owns all of our IDRs. If Crestwood Equity transfers its IDRs to a third party, Crestwood Equity may not have the same incentive to grow our partnership and increase quarterly distributions to common unitholders over time as it would if it had retained ownership of the IDRs.

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for U.S. federal income taxpurposes. If the Internal Revenue Service (“IRS”) were to treat us as a corporation forfederal income tax purposes or we were to become subject to material additionalamounts of entity-level taxation for state tax purposes, then our cash available fordistribution to unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a “qualifying income” requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement.

Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity. If we were treated as a corporation for U.S. federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which is currently a

36

maximum of 35%, as well as any applicable state or local taxes. Distributions to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us. At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise, or other forms of taxation. Imposition of a similar tax on us in the jurisdictions in which we operate or in other jurisdictions to which we may expand could substantially reduce our cash available for distribution to our unitholders.

The tax treatment of publicly traded partnerships or an investment in our commonunits could be subject to potential legislative, judicial or administrative changesand differing interpretations, possibly on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. For example, from time to time, members of Congress propose and consider substantive changes to the existing federal income tax laws that affect publicly traded partnerships. Currently, one such legislative proposal would have eliminated the qualifying income exception upon which we rely on for our treatment as a partnership for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will be reintroduced or will ultimately be enacted. Any such changes could negatively impact the value of an investment in our common units. Any modification to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes.

If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our cash available for distribution to our unitholders.

We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes. The IRS may adopt positions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. In addition, the costs of any contest with the IRS will be borne indirectly by you and our general partner because the costs will reduce our cash available for distribution.

You will be required to pay taxes on your share of our income even if you do not receive cash distributions from us.

You will be required to pay any federal income taxes and, in some cases, state and local income taxes on your share of our taxable income, whether or not you receive cash distributions from us. You may not receive cash distributions from us equal to your share of our taxable income or even equal to the actual tax liability which results from that income.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If you sell your common units, you will recognize a gain or loss equal to the difference between your amount realized and your tax basis in those common units. Because distributions in excess of your allocable share of our total net taxable income result in a reduction in your tax basis in your common units, the amount, if any, of such prior excess distributions with respect to the units you sell will, in effect, become taxable income to you if you sell such units at a price greater than your tax basis in those common units, even if the price you receive is less than your original cost. Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture of depreciation deductions. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if you sell your units, you may incur a tax liability in excess of the amount of cash you receive from the sale.

Tax-exempt entities, regulated investment companies and non-U.S. persons face unique tax issues from owning common units that may result in adverse tax consequences to them.

Investment in common units by tax-exempt entities, including employee benefit plans and individual retirement accounts (known as “IRAs”), and non-U.S. persons raises issues unique to them. For example, virtually all of our income allocated to organizations exempt from federal income tax, including individual retirement accounts and other retirement plans, will be

37

unrelated business taxable income and will be taxable to them. Distributions to non-U.S. persons will be reduced by withholding taxes imposed at the highest effective applicable tax rate, and non-U.S. persons will be required to file U. S. federal income tax returns and pay tax on their share of our taxable income. If you are a tax-exempt entity or a non-U.S. person, you should consult your tax advisor before investing in our common units.

We will treat each purchaser of our common units as having the same tax benefits without regard to the specific common units purchased. The IRS may challenge this treatment, which could adversely affect the value of our common units.

Because we cannot match transferors and transferees of common units and because of other reasons, we will adopt depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to you. It also could affect the timing of these tax benefits or the amount of gain from the sale of our common units and could have a negative impact on the value of our common units or result in audit adjustments to your tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The use of this proration method may not be permitted under existing Treasury Regulations. The U.S. Treasury Department has issued proposed Treasury Regulations that provide a safe harbor pursuant to which a publicly-traded partnership may use a similar monthly simplifying convention to allocate tax items among transferor and transferee unitholders. Nonetheless, the proposed regulations do not specifically authorize the use of the proration method we have adopted. If the IRS were to successfully challenge our proration method or new Treasury Regulations were issued, we may be required to change the allocation of items of income, gain, loss, and deduction among our unitholders.

A unitholder whose common units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short saleof common units) may be considered as having disposed of those common units. If so, hewould no longer be treated for tax purposes as a partner with respect to thosecommon units during the period of the loan and may recognize gain or loss from thedisposition.

Because there are no specific rules governing the U.S. federal income tax consequences of loaning a partnership interest, a unitholder whose common units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, he may no longer be treated for tax purposes as a partner with respect to those common units during the period of the loan and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller should modify any applicable brokerage account agreements to prohibit their brokers from borrowing their common units.

The sale or exchange of 50% or more of our capital and profits interests within a twelve-month period will result in the termination of our partnership for federal income tax purposes.

We will be considered to have constructively terminated as a partnership for federal income tax purposes if there is a sale or exchange within a twelve-month period of 50% or more of the total interests in our capital and profits. For purposes of determining whether the 50% threshold has been met, multiple sales of the same interest will be counted only once. Our termination would, among other things, result in the closing of our taxable year for all unitholders which could result in us filing two tax returns (and unitholders receiving two Schedule K-1s) for one calendar year. Our termination could also result in a deferral of depreciation deductions allowable in computing our taxable income. In the case of a unitholder reporting on a taxable year other than a calendar year, the closing of our taxable year may also result in more than twelve months of our taxable income or loss being includable in its taxable income for the year of termination. Our termination would not affect our classification as a partnership for federal income tax purposes, but instead, we would be treated as a new partnership for federal income tax purposes. If treated as a new partnership, we must make new tax elections and could be subject to penalties if we are unable to determine that a termination occurred. Pursuant to an IRS relief procedure a publicly traded partnership that has technically terminated may request special relief which, if granted by the IRS, among other things, would permit the partnership to provide only a single Schedule K-1 to unitholders for the tax years in which the termination occurs.

38

Our unitholders will likely be subject to state and local taxes and return filing requirements in states where they do not live as a result of investing in our common units.

In addition to federal income taxes, our unitholders will likely be subject to other taxes, including state and local taxes, unincorporated business taxes, estate, inheritance or intangible taxes and foreign taxes that are imposed by the various jurisdictions in which we do business or own property and in which they do not reside. We own property and conduct business in various parts of the United States. Unitholders may be required to file state and local income tax returns in many or all of the jurisdictions in which we do business or own property. Further, unitholders may be subject to penalties for failure to comply with those requirements. It is our unitholders' responsibility to file all required U. S. federal, state, local and foreign tax returns.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

A description of our properties is included in Item 1. Business, and is incorporated herein by reference. We also lease office space for our corporate offices in Houston, Texas and our executive offices in Kansas City, Missouri and Fort Worth, Texas.

We lease and rely upon our customers’ property rights to conduct a substantial portion of our gathering and processing operations, and we own the property rights necessary to conduct our storage and transportation operations. We believe that we have satisfactory title to our assets.

Title to property may be subject to encumbrances. For example, we have granted to the lenders of our revolving credit facility security interests in substantially all of our real property and real property interests located outside of the State of New York. We believe that none of these encumbrances will materially detract from the value of our properties or from our interest in these properties, nor will they materially interfere with their use in the operation of our business.

PART II

Item 5. Market for Registrant’s Common Equity, Related Unitholder Matters and Issuer Purchases of Equity Securities.

Prior to the Crestwood Merger, our common units traded on the NYSE under the symbol “NRGM.” Concurrent with the completion of the Crestwood Merger on October 7, 2013, our common units representing limited partner interests began trading on the NYSE under the symbol “CMLP.” The following table sets forth the range of high and low sales prices of the common units, as reported by the NYSE, as well as the amount of cash distributions declared per common unit for the periods indicated.

Quarters Ended:	Low		High		Cash Distribution Per Unit

March 31, 2012	18.69		22.15		0.370

The last reported sale price of our common units on the NYSE on February 14, 2014, was $23.75. As of that date, we had 187,934,087 common units issued and outstanding, which were held by 126 unitholders of record.

Cash Distribution Policy

We make quarterly distributions to our partners within approximately 45 days after the end of each fiscal quarter in an aggregate amount equal to our available cash for such quarter. Available cash generally means, with respect to each fiscal quarter, all cash on hand at the end of the quarter less the amount of cash that our general partner determines in its reasonable discretion is necessary or appropriate to:

• provide for the proper conduct of our business;

• comply with applicable law, any of our debt instruments, or other agreements; or

• provide funds for distributions to unitholders for any one or more of the next four quarters;

plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made subsequent to the end of the quarter. Working capital borrowings are generally borrowings that are made under our revolving credit facility and in all cases are used solely for working capital purposes or to pay distributions to partners.

On February 14, 2014, we paid a distribution of $0.41 per common unit ($1.64 per common unit on an annualized basis) to all unitholders of record on February 7, 2014.

Incentive Distribution Rights

CEQP holds IDRs that entitle it to receive 50% of all distributions paid by us in excess of our initial quarterly distribution of $0.37 per common unit.

Issuer Purchases of Equity Securities

For the year ended December 31, 2013, 21,014 common units were relinquished to Legacy Crestwood and 100,881 common units were relinquished to Legacy Inergy to cover payroll taxes upon the vesting of restricted units.

Item 6. Selected Financial Data.

Our consolidated financial statements were originally the financial statements of Legacy Crestwood prior to the Crestwood Merger on October 7, 2013. Crestwood Holdings acquisition of control of CEQP’s general partner on June 19, 2013 was accounted for as a reverse acquisition under the purchase method of accounting in accordance with accounting standards for business combinations.  The accounting for a reverse merger results in the legal acquiree (Crestwood Gas Services GP LLC) being the acquirer for accounting purposes.  The accounting acquiree (Inergy, inclusive of Inergy Midstream) was subject to the purchase method of accounting and its balance sheet was adjusted to fair market value as of June 19, 2013.  The merger of Legacy Crestwood and Inergy Midstream on October 7, 2013 was accounted for as a reverse merger amongst entities under common control.  Although Legacy Crestwood was the surviving entity for accounting purposes, Inergy Midstream was the surviving entity for legal purposes, and consequently we changed our name from Inergy Midstream, LP to Crestwood Midstream Partners, LP.  As the reverse merger was amongst entities under common control, the financial statements have been recast to reflect the operations of Inergy Midstream as being acquired by Legacy Crestwood on June 19, 2013, the date in which Inergy Midstream and Legacy Crestwood came under common control. 

The income statement and cash flow data for each of the three years ended December 31, 2013 and balance sheet data as of December 31, 2013 and 2012 were derived from our audited financial statements. We derived the income statement and cash flow data for each of the two years ended December 31, 2010 and the balance sheet data as of December 31, 2011, 2010 and 2009 from our accounting records. The selected financial data is not necessarily indicative of results to be expected in future periods and should be read together with Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations and Part IV, Item 15, Exhibits and Financial Statement Schedules included elsewhere in this report.

“EBITDA” shown in the table below is defined as income before income taxes, plus net interest and debt expense, and depreciation, amortization and accretion expense. In addition, Adjusted EBITDA considers the adjusted earnings impact of our unconsolidated affiliates by adjusting our equity earnings or losses from our unconsolidated affiliates for our proportionate share of their depreciation and interest, the impact of certain significant items, such as non-cash equity compensation expenses, gains and impairments of long-lived assets and goodwill, third party costs incurred related to potential and completed acquisitions, loss on contingent consideration, and other transactions identified in a specific reporting period. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, as they do not include deductions for items such as depreciation, amortization and accretion, interest and income taxes, which are necessary to maintain our business. EBITDA and Adjusted EBITDA should not be considered an alternative to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. EBITDA and Adjusted EBITDA calculations may vary among entities, so our computation may not be comparable to measures used by other companies.

(a) Financial data presented for periods prior to June 19, 2013, solely reflect the operations of Legacy Crestwood. Financial data for periods subsequent to June 19, 2013, represent the consolidated operations of Crestwood Midstream. In addition, during 2013, we recorded a $31.4 million loss on contingent consideration which reflects the fair value of an earn-out premium associated with the original acquisition of our Marcellus G&P assets from Antero in 2012.

(b) Diluted net income per unit for the years ended December 31, 2012, 2011, 2010 and 2009, were computed based on the number of common units issued by Legacy Inergy to Legacy Crestwood unitholders as part of the Crestwood Merger.

(c) Reported amounts include the fourth quarter distribution, which was paid in the first quarter of the subsequent year. In addition, for the year ended December 31, 2011, the amount includes the period beginning December 21, 2011 (the closing date of Legacy Inergy's IPO) through December 31, 2011. Accordingly, the $0.04 cash distribution per unit corresponds to a pro-rated quarterly distribution per unit of $0.37.

(d) Other long-term liabilities primarily include our capital leases and asset retirement obligations.

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our consolidated financial statements and the accompanying footnotes.

This report, including information included or incorporated by reference herein, contains forward-looking statements concerning the financial condition, results of operations, plans, objectives, future performance and business of our company and its subsidiaries. These forward-looking statements include:

• statements that are not historical in nature, including, but not limited to: (i) our expectation that we will grow our business through both organic growth projects and acquisitions; (ii) our belief that anticipated cash from operations, cash distributions from entities that we control, and borrowing capacity under our credit facility will be sufficient to meet our anticipated liquidity needs for the foreseeable future; (iii) our belief that we do not have material potential liability in connection with legal proceedings that would have a significant financial impact on our consolidated financial condition, results of operations or cash flows: (iv) our belief that our assets will continue to benefit from development of unconventional shale plays as significant supply basins; and (vi) our belief that the Crestwood Merger will produce certain commercial synergies and other benefits; and

• statements preceded by, followed by or that contain forward-looking terminology including the words “believe,” “expect,” “may,” “will,” “should,” “could,” “anticipate,” “estimate,” “intend” or the negation thereof, or similar expressions.

Forward-looking statements are not guarantees of future performance or results. They involve risks, uncertainties and assumptions. Actual results may differ materially from those contemplated by the forward-looking statements due to, among others, the following factors:

• our ability to successfully implement our business plan for our assets and operations:

• governmental legislation and regulations;

• industry factors that influence the supply of and demand for crude oil, natural gas and NGLs;

• industry factors that influence the demand for services in the markets (particularly unconventional shale plays) in which we provide services:

• weather conditions:

• the availability of crude oil, natural gas and NGLs, and the price of those commodities, to consumers relative to the price of alternative and competing fuels;

• economic conditions;

• costs or difficulties related to the integration of our existing businesses and acquisitions;

• environmental claims;

• operating hazards and other risks incidental to the provision of midstream services, including gathering, compressing, treating, processing, fractionating, transporting and storing crude oil, NGLs and natural gas;

• interest rates; and

• the price and availability of debt and equity financing.

We have described under Item 1A, Risk Factors, additional factors that could cause actual results to be materially different from those described in the forward-looking statements. Other factors that we have not identified in this report could also have this effect.

Overview

We are a growth-oriented MLP that manages, owns and operates crude oil, natural gas and NGL midstream assets and operations. Headquartered in Houston, Texas, we are a fully-integrated midstream solution provider that specializes in connecting shale-based energy supplies to key demand markets. We conduct gathering, processing, storage and transportation operations in the most prolific shale plays across the United States.

Strategic Business Combination

In 2013, we completed a series of related transactions that combined the management and operations of Legacy Inergy and Legacy Crestwood. The strategic rationale behind the business combination included, among other things, commercial synergies that would enable us to significantly expand the mix of midstream services we are able to offer our customers; diversified cash flows and asset base; increased scale to accelerate opportunities to reduce leverage and improve

44

creditworthiness; and, increased scale to better take advantage of growth opportunities, in terms of both organic growth projects and third-party acquisitions. We have already realized (and expect to continue to realize) many of these anticipated merger benefits, and we continue to believe this strategic combination enhances our position as a diversified, high-growth midstream “pure play” focused on crude and liquids-rich opportunities.

Our Company

We provide broad-ranging services to customers across the crude oil, NGL and natural gas sector of the energy value chain. Our midstream infrastructure is geographically located in or near significant supply basins, especially developed and emerging liquids-rich and crude oil shale plays, across the United States. We own or control:

• natural gas facilities with approximately 2.5 Bcf/d of gathering capacity, 471 MMcf/d of processing capacity, 41 Bcf of working gas storage capacity, and 1.0 Bcf/d of firm transmission capacity;

• NGL facilities with approximately 1.7 million barrels of storage capacity; and

• crude oil facilities with approximately 100,000 Bbls/d of gathering capacity, 960,000 barrels of storage capacity and 120,000 Bbls/d of rail loading capacity.

Our primary business objective is to increase the cash distributions that we pay to our unitholders. We intend to grow our business safely through the development, acquisition and operation of additional midstream assets situated near developed and emerging shale resources and premium demand centers. We plan to increase cash available for distribution through organic growth and increased operational efficiencies, including commercial and operational synergies resulting from the Crestwood Merger. We also anticipate growing our business through strategic and bolt-on acquisitions, including asset drop downs, with an emphasis on acquisitions that (i) facilitate our development of an integrated midstream platform that enables us to continue to expand the services we offer to customers in key geographic markets, and/or (ii) provide the scale we need to realize greater economies of scale (from cash flow, cost, credit and other perspectives) that translate into increased cash distributions to our unitholders.

Our three business segments include (i) gathering and processing, which includes our natural gas G&P operations; (ii) NGL and crude services, which includes our crude oil gathering systems and rail terminals, NGL storage facility and salt production business; and (iii) storage and transportation, which includes our natural gas storage and transportation operations.

Gathering and Processing

Our G&P operations provide gathering, compression, treating, and processing services to producers in multiple unconventional resource plays across the United States. We have established footprints in “core of the core” areas of several shale plays with delineated condensate and rich gas windows offering attractive producer economics, while maintaining operations in several prolific dry gas plays. We believe that our strategy of focusing on liquids-rich plays without abandoning prolific lean gas plays positions us well to (i) generate greater returns in the near term while natural gas prices remain depressed, (ii) capture greater upside economics when natural gas prices normalize, and (iii) in general, manage through commodity price cycles and production changes associated therewith.

Our G&P operations primarily include:

• Marcellus Shale. We own and operate (i) a low-pressure natural gas gathering system with a gathering capacity of approximately 600 MMcf/d of rich gas produced by our customers in Harrison and Doddridge Counties, West Virginia; (ii) six compression and dehydration stations located on our gathering systems in the East AOD; and (iii) one compressor station located in the Western Area;

• PRB Niobrara Shale. We own a 50% ownership interest in Jackalope, which is developing a system to gather and process rich natural gas produced in Converse County, Wyoming from a 311,000 gross acreage dedication from Chesapeake and RKI. We funded a significant portion of our Jackalope purchase in July 2013 with the sale to GE of non-voting preferred equity securities in our Crestwood Niobrara subsidiary. We consolidate Crestwood Niobrara’s results in our financial statements, and we account for Crestwood Niobrara’s 50% interest in Jackalope as an equity investment;

45

• Barnett Shale. We own and operate (i) a low-pressure natural gas gathering system with a gathering capacity of approximately 425 MMcf/d of rich gas produced by our customers in Hood, Somervell and Johnson Counties, Texas, which delivers the rich gas to our two processing plants where NGLs are extracted from the natural gas stream; and (ii) low-pressure gathering systems with a gathering capacity of 530 MMcf/d of dry natural gas produced by our customers in Tarrant and Denton Counties, Texas;

• Fayetteville Shale. We own and operate five low-pressure gas gathering systems with a gathering capacity of approximately 510 MMcf/d of dry natural gas produced by our customers in Conway, Faulkner, Van Buren, and White Counties, Arkansas; and

• Other. We own and operate (i) a low-pressure natural gas gathering system with a gathering capacity of approximately 36 MMcf/d of rich gas produced by our customers in Roberts County, Texas, and a processing plant that extracts NGLs from the natural gas stream (Granite Wash system); (ii) three low-pressure natural gas gathering systems with a gathering capacity of approximately 50 MMcf/d of rich gas produced by our customers in Eddy County, New Mexico (Avalon/Bone Springs system); and (iii) high-pressure natural gas gathering pipelines with a gathering capacity of approximately 100 MMcf/d that provide gathering and treating services to our customers located in Sabine Parish, Louisiana (Haynesville/Bossier system).

The cash flows from our G&P operations are predominantly fee-based with creditworthy counterparties under contracts with terms that average 5-20 years. The results of our G&P operations are significantly influenced by the volumes of natural gas gathered and processed through our systems. We gather, process, treat, compress, transport and sell natural gas pursuant to fixed-fee and, to a lesser extent, percent-of-proceeds contracts. We do not take title to natural gas or NGLs under our fixed-fee contracts, whereas under our percent-of-proceeds contracts, we take title to the residue gas, NGLs and condensate and remit a portion of the sale proceeds to the producer based on prevailing commodity prices. Our election to enter primarily into fixed-fee contracts minimizes our G&P segment’s commodity price exposure and provides us more stable operating performance and cash flows. For the year ended December 31, 2013, the net revenues from our percent-of-proceeds contracts accounted for approximately 2% of our gross profit (defined as revenues less costs of product/services sold) in our G&P operations.

NGL and Crude Services

Our NGL and crude services segment consists of our crude oil gathering systems and rail terminals, NGL storage facilities and US Salt. We have facilities located in the core of the Bakken Shale, one of the most prolific crude oil shales in North America, and the premium Northeast demand market. We utilize these facilities to provide gathering, storage and terminal services to our anchor customers, and we utilize our crude oil and NGL assets on a portfolio basis to provide integrated supply and logistics solutions to producers, refiners and other customers.

Our NGL and crude services operations primarily include:

• Bakken Shale - Arrow. We own and operate substantial crude oil, natural gas and produced water gathering systems (the Arrow system) located on the Fort Berthold Indian Reservation in the core of the Bakken Shale in McKenzie and Dunn Counties, North Dakota. The Arrow system consists of more than 485 miles of gathering pipeline, including approximately 153 miles of crude oil gathering lines, 171 miles of natural gas gathering lines and 164 miles of produced water gathering lines. We purchased the Arrow system in November 2013;

• Bakken Shale - COLT Hub. We own and operate the COLT Hub, which is one the largest crude oil rail terminals in the Bakken Shale based on actual throughput and which complements our recent Arrow acquisition. Located approximately 60 miles away from Arrow’s central delivery point, the COLT Hub interconnects with the Arrow system through the Hiland and Tesoro pipeline systems. The hub, which can be sourced by numerous pipeline systems or truck, is capable of loading up to 120,000 Bbls/d and has 960,000 barrels of crude oil storage capacity;

• PRB Niobrara Shale. We own a 50.01% ownership interest in PRBIC, which owns an early stage crude oil rail terminal in Douglas County, Wyoming. We account for our interest in PRBIC as an equity investment. The terminal, which when completed will provide unit train takeaway-solutions for crude producers in the PRB Niobrara, is supported by a long-term contract with a major oil producer under which the producer has committed to deliver a minimum volume of crude oil to the rail facility for throughput;

• Bath storage facility. Our Bath facility, a 1.7 million barrel underground NGL storage facility in Bath, New York, is supported by rail and truck terminal facilities capable of loading and unloading 23 railcars and approximately 100 truck transports per day; and

46

• US Salt. Our salt production business, which has a plant near Watkins Glen, New York, is capable of producing more than 400,000 tons of evaporated salt products annually. US Salt’s solution mining process creates underground caverns that can be developed into natural gas and NGL storage capacity.

The PRBIC joint venture is also an example of how the Crestwood Merger is delivering commercial synergies, as this opportunity resulted from a combination of the crude rail terminal and NGL logistics experience of Legacy Inergy and Legacy Crestwood’s relationships with RKI and Jackalope.

The cash flows from the Arrow operations are primarily fee-based with creditworthy counterparties under 10-to-20 year contracts, and can be impacted in the short term by changing commodity prices, seasonality and weather fluctuations. The cash flows from our Bakken Shale COLT Hub are predominantly fee-based with creditworthy counterparties under three-to-five year contracts, and are generally economically stable and not significantly affected in the short term by changing commodity prices, seasonality or weather fluctuations. The cash flows from our salt operations represent sales to creditworthy customers typically under contracts that are less than one year in duration, and are relatively stable and not subject to seasonal or cyclical variation due to the use of, and demand for, salt products in everyday life.

Storage and Transportation

Our storage and transportation segment consists of our natural gas storage and transportation assets. We have four natural gas storage facilities (Stagecoach, Thomas Corners, Steuben and Seneca Lake) and three transportation pipelines (North-South Facilities, MARC I and the East Pipeline) located in the Northeast in or near the Marcellus Shale. Our interconnected facilities provide 41 Bcf of firm storage capacity and more than 1.0 Bcf/d of firm transportation capacity to producers, utilities, marketers and other customers. We believe the location of our storage and transportation assets relative to New York City and other premium demand markets along the East Coast helps to insulation our operations from production and commodity price changes that can more easily impact storage and transportation operators in other geographic regions.

The cash flows from our storage operations are predominantly fee-based with creditworthy counterparties under one-to-ten year contracts, and the cash flows from our transportation operations are predominantly fee-based with creditworthy counterparties under five-to-ten year contracts. Our cash flows from interruptible and other hub services tends to increase during the peak winter season.

Outlook and Trends

Our long-term profitability will be influenced primarily by our ability to execute our growth strategy, including both growth projects and strategic acquisitions, and to increase cash available for distribution from the assets we own or control. An integral part of our growth strategy entails capitalizing on commercial synergies from the Crestwood Merger. We continue to expand the services from which we generate revenues from our gathering and processing customer base, and we anticipate generating increased cash flows as our producer customers rely on us for more integrated NGL and crude oil takeaway solutions and flow assurances. We also anticipate pursuing acquisitions that would not have been possible without the combined expertise and relationships resulting from the business combination. The continued integration of our gathering, processing, marketing, storage and transportation experience will be instrumental to our ability to derive such commercial synergies.

Organic growth projects, including both expansions and greenfield development projects, can provide cost-effective options for us to grow our infrastructure base. The ongoing expansion of our Bakken assets, including the COLT Hub and the Arrow system, and continued build out of our Marcellus and PRB Niobrara systems are examples of our ability to internally grow our operations at very low multiples. In general, purchasers of energy infrastructure have paid relatively high prices (measured in terms of a multiple of EBITDA or another financial metric) to acquire midstream assets and operations in recent arms-length transactions. Although the prices paid for certain types of midstream assets are likely to remain robust for the foreseeable future, acquisitions will continue to permit us to gain access to new markets (with respect to geographic footprint and product offerings) and develop the scale required to continue to grow our businesses quickly and successfully. Our Arrow acquisition and our Jackalope and PRBIC investments are examples of where we believe we can cost-effectively accelerate growth through third-party acquisitions. We therefore expect to grow our business in the near term through both organic growth projects and acquisitions.

Our long-term profitability will also depend on our ability to contract and re-contract with customers and to manage increasingly difficult regulatory processes at the federal, state and local levels. The time required to secure the authorizations necessary for development projects and expansions, for both unregulated and regulated projects, and the amounts we pay to secure authorizations and land rights are increasing in most markets in which we participate. Our Watkins Glen NGL storage

47

project is a prime example of the increased political and regulatory challenges we face in certain regions, despite the obvious market need for NGL storage solutions in the Northeast. However, we remain confident that the incremental time and money required to pursue and complete market-driven solutions will deliver meaningful value to our unitholders, as the combination of the ongoing regulatory climate and the location of our assets relative to both high-demand markets and prolific shale basins effectively provides a significant barrier to entry that other market participants may find difficult to overcome.

We remain confident that production levels in the Marcellus, Bakken and PRB Niobrara Shale plays will remain strong, particularly as new gas processing capacity and pipeline takeaway options come online in the next few years. We expect the producer economics in these oily (Bakken) and rich gas (Marcellus) windows to remain strong based on published supply and demand forecasts. In general, we believe that producers will continue to shift their resources to crude oil and liquids-rich regions until natural gas demand increases and prices normalize. Accordingly, certain producers may continue to divert resources away from dry gas plays (e.g., Fayetteville and Haynesville), which could negatively impact the volumes flowing through our gathering systems in these plays.

We continue to forecast strong demand for natural gas and NGL storage in the Northeast, due mainly by a shortage in supply deliverability options and storage infrastructure near key demand markets and a higher than average annual demand growth. We expect strong demand for natural gas pipelines that move production volumes directly to the market, and softer demand for pipeline capacity that can be displaced by new pipelines and expansion projects brought on line (particularly, new capacity used to move local production directly to local demand centers). We also believe that the location of our facilities in the Northeast positions us well to capitalize on opportunities associated with both (i) the current downward trend of increasingly lower import volumes of NGLs and liquefied natural gas along the East Coast and (ii) anticipated increases in exported volumes of liquefied natural gas as new liquefaction facilities along the East Coast come online.

How We Evaluate Our Operations

We evaluate our overall business performance based primarily on EBITDA and Adjusted EBITDA. We evaluate our ability to make distributions to our unitholders based on cash available for distributions.

We do not utilize depreciation, depletion and amortization expense in our key measures because we focus our performance management on cash flow generation and our assets have long useful lives.

EBITDA and Adjusted EBITDA - We believe that EBITDA and Adjusted EBITDA are widely accepted financial indicators of a company's operational performance and its ability to incur and service debt, fund capital expenditures and make distributions. EBITDA is defined as income before income taxes, plus net interest and debt expense, and depreciation, amortization and accretion expense. In addition, Adjusted EBITDA considers the adjusted earnings impact of our unconsolidated affiliates by adjusting our equity earnings or losses from our unconsolidated affiliates for our proportionate share of their depreciation and interest, the impact of certain significant items, such as non-cash equity compensation expenses, gains and impairments of long-lived assets and goodwill, third party costs incurred related to potential and completed acquisitions, loss on contingent consideration, and other transactions identified in a specific reporting period. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, as they do not include deductions for items such as depreciation, amortization and accretion, interest and income taxes, which are necessary to maintain our business. EBITDA and Adjusted EBITDA should not be considered an alternative to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. EBITDA and Adjusted EBITDA calculations may vary among entities, so our computation may not be comparable to measures used by other companies.

See our reconciliation of net income to EBITDA and Adjusted EBITDA in Results of Operations below.

Segment Results

Below is a discussion of the factors that impacted EBITDA by segment for the three years ended December 31, 2013, 2012 and 2011.

Gathering and Processing:

Revenues for our gathering and processing ("G&P") segment increased by approximately $51.7 million (or 22%) during the year ended December 31, 2013 compared to the same period in 2012, although our G&P segment’s EBITDA decreased by $7.7 million for that same period. The decrease in EBITDA was primarily the result of a $31.4 million loss on contingent consideration recorded during 2013. This non-cash accrual reflects the fair value of an earn-out premium associated with the original acquisition of our Marcellus G&P assets from Antero in 2012. This earn-out provision allows Antero to receive an additional $40 million payment during the first quarter of 2015 if gathering volumes exceed a certain threshold in the acquisition agreements, which was based on original acquisition forecasts. Based on our current forecasts, we believe our Marcellus gathering volumes will exceed that threshold in 2014.

Partially offsetting this decrease in EBITDA year-over-year was a $22.3 million increase in the operating margin (defined as operating revenues less costs of product/services sold and operating and administrative expense) due to a 21% increase in gathering volumes and an increase in compression volumes in 2013 compared to 2012. We gathered approximately 365 Bcf of natural gas on our G&P systems in 2013, compared to 301 Bcf in 2012, which was primarily driven by our acquisition of assets

51

from Antero and Devon Corporation (“Devon”) in 2012 and continued expansion of our assets in the Marcellus Shale in order to capitalize on increased producer activity. We compressed approximately 107 Bcf of natural gas on our Marcellus system during 2013, which related primarily to the acquisition of assets from Enerven Compression, LLC (“Enerven”) in December 2012 and construction of additional compression assets in the Marcellus Shale.

Our G&P EBITDA for the year ended December 31, 2012 increased by approximately $25.6 million compared to the same period in 2011. This was due primarily to an increase in our gathering volumes resulting from the acquisitions from Antero and Devon.

During the years ended December 31, 2013 and 2011, several other significant transactions impacted our G&P segment which were not related to our core operating activities:

Year Ended December 31, 2013:

• $4.4 million gain on sale of a cryogenic plant and associated equipment;

• $4.1 million impairment of goodwill on our Haynesville/Bossier Shale operations as a result of a decrease in anticipated revenues due primarily to our inability to renew and extend a significant revenue contract that expired in mid-2013; and

• $31.4 million loss on contingent consideration in connection with the acquisition of the Antero assets. See “Critical Accounting Estimates” below for a further discussion of the contingent consideration.

Year Ended December 31, 2011:

• $1.1 million gain on the exchange of property, plant and equipment

On July 19, 2013, Crestwood Niobrara acquired a 50% interest in a gathering system located in the PRB Niobrara for $107.5 million. For the year ended December 31, 2013, we recorded earnings from our unconsolidated affiliate, Jackalope, of approximately $0.1 million, which primarily related to (i) our proportionate share of Jackalope’s net income and (ii) the amortization of the excess of our investment balance compared to Jackalope’s net assets which was approximately $1.4 million for the year ended December 31, 2013. For the period from July 19, 2013 to December 31, 2013, Jackalope gathered 45 MMcf/d of natural gas through its assets.

NGL and Crude Services:

Our NGL and crude services segment reflects only the results of our operations from June 19, 2013 (the date that Crestwood Holdings acquired control of CEQP’s general partner) to December 31, 2013. Accordingly, the following discusses the results of operations of our NGL and crude services segment for the six months ended December 31, 2013.

Our NGL and crude services segment’s EBITDA was significantly impacted by our COLT Hub crude oil terminal in the Bakken Shale, which contributed a majority of the segment's EBITDA during the six months ended December 31, 2013. We have entered into contracts with several customers to provide additional throughput and storage services that began in the fourth quarter of 2013, which we believe will positively contribute to the EBITDA generated by the COLT Hub in the future.

On November 8, 2013, we acquired Arrow Midstream Holdings, LLC ("Arrow"), which owns substantial crude oil, natural gas and water gathering systems located in the Bakken Shale. Accordingly, Arrow's operations only contributed to our NGL and crude services segment's EBITDA for the period from November 8, 2013 to December 31, 2013. We believe that these operations will contribute additional EBITDA in the future to our NGL and crude services segment through its core crude, natural gas and water gathering services, and by enhancing commercial opportunities for our COLT Hub and our other NGL and crude businesses.

Storage and Transportation:

Our storage and transportation segment reflects only the results of our operations from June 19, 2013 (the date that Crestwood Holdings acquired control of CEQP’s general partner) to December 31, 2013. Accordingly, the following discusses the results of operations of our storage and transportation segment for the six months ended December 31, 2013.

Our storage and transportation segment’s EBITDA was driven primarily by our Stagecoach natural gas storage facility and our MARC I pipeline located in the Marcellus Shale, which combine contributed $58.7 million of the segment’s EBITDA during the six months ended December 31, 2013. Our MARC I pipeline has experienced favorable revenues from its interruptible

52

services as well as continued demand for transportation capacity in the region. Our North-South Facilities continue to benefit from high demand for their interruptible wheeling services from producers and other customers given transportation basis spreads in the region.

Other Results

Our consolidated EBITDA for the year ended December 31, 2013 was $178.7 million, an increase of $50.9 million from 2012 and an increase of $20.1 million for the year ended December 31, 2012 compared to 2011. Our consolidated Adjusted EBITDA for the year ended December 31, 2013 was $261.9 million, an increase of $127.5 million from 2012 and an increase of $23.5 million for the year ended December 31, 2012 compared to 2011.

The increase in our EBITDA and Adjusted EBITDA was primarily driven by our segment results described above. Partially offsetting those results were the operating and administrative costs of our Corporate and other operations, which totaled $80.7 million, $29.6 million and $24.1 million for the years ended December 31, 2013, 2012 and 2011. The increase in these operating and administrative costs were driven by the assets acquired as a result of the Crestwood Merger in 2013 and the Antero, Devon and Enerven acquisitions during 2012. Also contributing to the increase was primarily legal and other consulting expenses we incurred to evaluate certain transaction opportunities, which were approximately $34.7 million, $4.7 million and $3.4 million during the years ended December 31, 2013, 2012 and 2011. We also had increases in payroll and related benefit costs, which reflects the increased scope of our business operations, and an increase of $13.9 million and $1.0 million of expenses related to our equity compensation plans during the years ended December 31, 2013 and 2012.

Items not affecting EBITDA include the following:

Depreciation, Amortization and Accretion Expense - During the year ended December 31, 2013, our depreciation, amortization and accretion expense increased compared to 2012 and 2011 primarily due to the assets acquired from Antero, Devon and Enerven during 2012. In addition, we recorded approximately $49.7 million of depreciation and amortization expense related to our NGL and crude services assets and our storage and transportation assets from June 19, 2013 (the date that Crestwood Holdings acquired control of CEQP's general partner) to December 31, 2013, which contributed to our increase year over year.

Interest and Debt Expense - Interest and debt expense increased for the year ended December 31, 2013 compared to 2012 and 2011, primarily due to (i) higher outstanding balances on our credit facilities, net of repayments; (ii) the issuance of an additional $150 million of 7.75% senior notes in November 2012; (iii) the assumption of $1.1 billion of long-term debt due to the Crestwood Merger; and (iv) the issuance of $600 million of 6.125% senior notes in November 2013.

Liquidity and Sources of Capital

We are a partnership holding company that derives all of our operating cash flow from our operating subsidiaries.  Our principal sources of liquidity include cash generated by operating activities, credit facilities, debt issuances, and sales of our common units.   Our operating subsidiaries use cash from their respective operations to fund their operating activities and maintenance capital expenditures.  We use cash generated by our operating subsidiaries and, if applicable, borrowings under our Credit Facility (defined below) to service our outstanding indebtedness, fund growth capital expenditures, and make distributions to unitholders.  We do not guarantee indebtedness of, or have similar commitments to, our affiliates, including Crestwood Holdings or CEQP.

53

We believe that anticipated cash from operations, available borrowing capacity under our credit facility and the issuances of additional debt and equity in the capital markets will be sufficient to meet our liquidity needs for the foreseeable future. However, to the extent we need to raise additional capital, we cannot provide assurances that we will be able to raise the additional capital to meet these needs.

Contemporaneously with the closing of the Crestwood Merger, we entered into a $1 billion five-year senior secured revolving credit facility (the “Credit Facility”) with a syndicate of financial institutions. We believe this facility is sized sufficiently to fund our growth plans and working capital needs. We borrowed funds under the Credit Facility (i) to repay in full and retire the credit facilities of Legacy Inergy, Legacy Crestwood and Crestwood Marcellus Midstream LLC (“CMM”); and (ii) to pay fees and expenses relating to the Crestwood Merger and related transactions. From time to time thereafter, we may borrow funds under the Credit Facility for general partnership purposes, including acquisitions. Subject to limited exception, the Credit Facility is secured by substantially all of the equity interests and assets of our domestic restricted subsidiaries, and is jointly and severally guaranteed by substantially all of our domestic restricted subsidiaries. As of December 31, 2013, we had $554.4 million of remaining capacity under the Credit Facility.

See Part IV, Item 15, Exhibits and Financial Statement Schedules, Note 7 for a more detailed description of our Credit Facility.

Operating Activities

During the year ended December 31, 2013, we experienced an increase in our operating revenues compared to 2012 and 2011 primarily due to (i) asset acquisitions during 2012; and (ii) revenues of approximately $367.4 million related to our NGL and crude and storage and transportation segments from June 19, 2013 (the date that Crestwood Holdings acquired control of CEQP's general partner) to December 31, 2013. Partially offsetting these increases in operating revenues was higher operating and administrative expenses and costs of product/services sold. In addition, our interest costs increased due to higher outstanding balances on our credit facilities.

Investing Activities

The energy midstream business is capital intensive, requiring significant investments for the acquisition or development of new facilities. We categorize our capital expenditures as either:

• growth capital expenditures, which are made to construct additional assets, expand and upgrade existing systems, or acquire additional assets; or

• maintenance capital expenditures, which are made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets, extend their useful lives or comply with regulatory requirements.

The following table summarizes our capital expenditures for the year ended December 31, 2013 (in millions). We have identified additional growth capital project opportunities for each of our reporting segments. Additional commitments or expenditures will be made at our discretion, and any discontinuation of the construction of these projects will likely result in less future cash flow and earnings.

Growth capital	$	309.1
Maintenance capital	11.6
Other(1)	13.9
Total	$	334.6

(1)     Represents capital expenditures that are reimbursable by third parties.

54

During 2014, we anticipate growth capital expenditures of approximately $400 million to $425 million, which includes contributions to our equity investments related to their capital projects. In addition, we expect to spend between $20 million to $23 million on maintenance capital expenditures. We anticipate that our growth capital expenditures in 2014 will increase the gathering, processing, compression and overall capacity of our systems, primarily in the Marcellus, Bakken and PRB Niobrara Shales. We expect to finance our growth and maintenance capital expenditures through additional capital market transactions, borrowings under our credit facility and operating cash flows.

Our cash flows from investing activities were impacted by the following significant items during the three years ended December 31, 2013, 2012 and 2011.

Year Ended December 31, 2013:

In November 2013, we paid approximately $750 million to acquire the Arrow crude oil, natural gas and produced water gathering systems in the Bakken. In addition, during the year ended December 31, 2013, we invested an additional $24.9 million in the Arrow system to fund its continued build out.

In September 2013, Crestwood Crude Logistics LLC paid approximately $22.5 million to acquire a 50.01% interest in PRBIC, which is developing a crude oil rail terminal to serve producers in the PRB Niobrara. In addition, during the year ended December 31, 2013, we contributed an additional $1.9 million to PRBIC to funds its construction plans.

In July 2013, Crestwood Niobrara paid $107.5 million to acquire a 50% interest in Jackalope, which is developing a gathering and processing system located in the PRB Niobrara play for Chesapeake, RKI and other producers. In addition, during the year ended December 31, 2013, Crestwood Niobrara contributed an additional $19.6 million to Jackalope to fund its construction projects.

Year Ended December 31, 2012:

During the year ended December 31, 2012, we paid approximately $564.0 million to acquire assets from Antero, Devon and Enerven. In addition, we spent approximately $52.6 million on capital expenditures, including $4.1 million related to maintenance capital expenditures.

Year Ended December 31, 2011:

During the year ended December 31, 2011, we paid approximately $414.1 million to acquire our Fayetteville, Granite Wash, Las Animas and Sabine systems. In addition, we received approximately $6.0 million related to the exchange of property, plant and equipment.

Financing Activities

Significant items impacting our financing activities during the three years ended December 31, 2013, 2012 and 2011 included the following:

Equity Transactions

• $595.5 million of net proceeds from the issuance of Legacy Inergy common units in 2013;

• $118.5 million, $217.5 million and $53.6 million of net proceeds from the issuance of Legacy Crestwood common units in 2013, 2012 and 2011;

• $152.7 million in net proceeds from the issuance of Legacy Crestwood Class C units in 2011;

•

• $8.7 million contribution from the general partner of Legacy Crestwood to maintain its 2% general partner interest during 2011;

Debt Transactions

• $2,072.8 million, $706.7 million and $415.2 million of net proceeds from the issuance of long-term debt in 2013, 2012 and 2011;

• $1,634.3 million, $534.0 million and $186.2 million of principal payments on our long-term debt in 2013, 2012 and 2011; and

55

Other

• The payment of Sabine System acquisition deferred payment of approximately $8 million in 2012.

In January 2013, Legacy Crestwood acquired Crestwood Holdings’ 65% membership interest in CMM for approximately $258.0 million, which was funded through $129.0 million of borrowings under Legacy Crestwood's credit facility and the issuance of approximately $129.0 million of equity to Crestwood Holdings.

In July 2013, Crestwood Niobrara acquired a 50% interest in a joint venture which was funded through (i) a capital contribution of approximately $26.9 million by Legacy Crestwood, which it funded with borrowings under its credit facility, and (ii) Crestwood Niobrara’s issuance of approximately $80.6 million of preferred securities to GE. Crestwood Niobrara expects to fund up to 75% of its future capital contributions to Jackalope through the issuance of additional preferred securities to GE (up to a maximum of an additional $53.9 million), with the remaining portion of such capital contributions to be funded by our capital contributions to Crestwood Niobrara. During the year ended December 31, 2013, GE contributed an additional $15.5 million to Crestwood Niobrara in exchange for an equivalent number of preferred units. We serve as the managing member of Crestwood Niobrara and, subject to certain restrictions, have the ability to redeem GE’s preferred securities in either cash or our common units.

In November 2013, we issued 8,826,125 common units as part of the consideration paid for the acquisition of Arrow.

Off-Balance Sheet Arrangements

We had no significant off-balance sheet arrangements as of December 31, 2013.

Contractual Obligations

We are party to various contractual obligations. A portion of these obligations are reflected in our financial statements, such as long-term debt and other accrued liabilities, while other obligations, such as operating leases, capital commitments and contra ctual interest amounts are not reflected on our balance sheet. The following table and discussion summarizes our contractual cash obligations as of December 31, 2013 (in millions):

	Less than 1 Year		1-3 Years		3-5 Years		Thereafter		Total
Long-term debt:
Principal	$	2.9	$	—	$	412.0	$	1,450.0	$	1,864.9

Critical Accounting Estimates

The preparation of financial statements in conformity with GAAP requires management to select appropriate accounting estimates and to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. We consider our critical accounting estimates to be those that require difficult, complex, or subjective judgment necessary in accounting for inherently uncertain matters and those that could significantly influence our financial results based on changes in those judgments. Changes in facts and circumstances may result in revised estimates and actual results may differ materially from those estimates. We have discussed the development and selection of the following critical accounting estimates and related disclosures with the Audit Committee of the board of directors of our general partner.

Long-Lived Assets

Our long-lived assets consist primarily of property, plant and equipment and intangible assets that have been obtained through multiple historical business combinations. The initial recording of a majority of these long-lived assets was at fair value, which is estimated by management primarily utilizing market-related information and other projections on the performance of the assets acquired. Management reviews this information to determine its reasonableness in comparison to the assumptions utilized in determining the purchase price of the assets in addition to other market-based information that was received through the purchase process and other sources. Due to the imprecise nature of the projections and assumptions utilized in determining fair value, actual results can, and often do, differ from our estimates.

We also utilize assumptions related to the useful lives and related salvage value of our property, plant and equipment in order to determine depreciation and amortization expense each period. Due to the imprecise nature of the projections and assumptions utilized determining useful lives, actual results can, and often do, differ from our estimates.

To estimate the useful life of our finite lived intangible assets we utilize assumptions of the period over which the assets are expected to contribute directly or indirectly to our future cash flows. Generally this requires us to amortize our intangible asset based on the expected future cash flows, to the extent they are readily determinable, of the acquired contracts or customer relationship. Due to the imprecise nature of the projections and assumptions utilized determining future cash flows, actual results can, and often do, differ from our estimates.

We continually monitor our business, the business environment and the performance of our operations to determine if an event has occurred that indicates that a long-lived asset may be impaired. If an event occurs, which is a determination that involves judgment, we may be required to utilize cash flow projections to assess our ability to recover the carrying value of our assets based on our long-lived assets' ability to generate future cash flows on an undiscounted basis. Projected cash flows of the asset are generally based on current and anticipated future market conditions, which require significant judgment to make projections and assumptions about pricing, demand, competition, operating costs, construction costs, legal and regulatory issues and other factors that may extend many years into the future and are often outside of our control. If those cash flow projections indicate that the long-lived asset's carrying value is not recoverable, we record an impairment charge for the excess of carrying value of the asset over its fair value. The estimate of fair value considers a number of factors, including the potential value we would receive if we sold the asset, discount rates and projected cash flows. Due to the imprecise nature of these projections and assumptions, actual results can and often do, differ from our estimates.

The value of the assets to be disposed of is estimated at the date a commitment to dispose the asset is made. Our estimate of any loss associated with an asset sale is dependent on certain assumptions we make with respect to the net realizable value of the particular asset.

We have not recorded any significant impairments of our long-lived assets during 2013, 2012 or 2011.

Goodwill Impairment

Our goodwill represents the excess of the amount we paid for a business over the fair value of the net identifiable assets acquired. We evaluate goodwill for impairment annually, and whenever events or changes indicate that it is more likely than not that the fair value of a reporting unit could be less than its carrying amount. This evaluation requires us to compare the fair value of each of our reporting units to its carrying value (including goodwill). If the fair value exceeds the carrying amount, goodwill of the reporting unit is not considered impaired. In conjunction with the reverse merger, we modified our segments and now our financial statements reflect three operating and reporting segments; (i) gathering and processing operations; (ii) NGL and crude services operations; and (iii) storage and transportation operations. We have identified eight reporting units within these three operating and reporting segments. We had approximately $1.7 billion of goodwill as of December 31, 2013,

57

the substantial majority of which was related to our storage and transportation assets in or near the Marcellus Shale, our COLT Hub terminal and related operations in the Bakken Shale, and our gathering and processing operations in the Barnett Shale.

We estimate the fair value of our reporting units based on a number of factors, including the potential value we would receive if we sold the reporting unit, enterprise value, discount rates and projected cash flows. Estimating projected cash flows requires us to make certain assumptions as it relates to future operating performance. When considering operating performance, various factors are considered such as current and changing economic conditions and the commodity price environment, among others. Due to the imprecise nature of these projections and assumptions, actual results can and often do, differ from our estimates. If the growth assumptions embodied in the current year impairment testing prove inaccurate, we could incur an impairment charge.

We utilized a qualitative goodwill impairment assessment at December 31, 2013 for the goodwill recorded as part of the Crestwood Merger. The qualitative assessment was utilized for this goodwill due to the recent fair value calculation performed as part of the purchase accounting for the reverse acquisition. No impairment indicators were identified as part of this qualitative assessment. We utilized a quantitative goodwill impairment assessment for all other goodwill at December 31, 2013.

Based on our goodwill impairment analysis at December 31, 2013, we believe that a 5% decrease in the estimated future cash flows or a 1% increase in the discount rate used to estimate the fair value of our reporting units would not have resulted in a material impairment of our goodwill related to any of our reporting units for which we performed a quantitative goodwill impairment assessment, other than potentially the $14.2 million of goodwill related to our Granite Wash reporting unit.

During the year ended December 31, 2013, we recorded an impairment of goodwill of approximately $4.1 million on our Haynesville/Bossier Shale system as a result of a decrease in anticipated revenues to be generated from those operations due primarily to our inability to renew and extend a significant revenue contract that expired in mid-2013.

Revenue Recognition

We gather, treat, compress, process, store, transport and sell various commodities pursuant to fixed-fee and percent-of-proceeds contracts. We recognize revenue on these contracts when certain criteria are met, the most important of which is that the delivery of the service has been performed. Certain of our contracts in our NGL and crude services segment and our gathering and processing segment contain minimum volume features under which the customers must deliver a set quantity of crude or gas or pay a deficiency fee based on the amount the customers’ actual volume is short of the contractual minimum volume. The minimum volume feature generally allows customers a recoupment period in subsequent periods to make up certain previous volumetric shortfalls by delivering additional crude or gas above their minimum threshold. We recognize revenue from these contracts based on the physical volume that is delivered to our systems in the current period and any minimum volume deficiency amounts billable to customers under the minimum volume features are recorded as a deferred revenue liability until we determine that the revenue is earned. We will recognize the deferred revenue as income at such time as the customer does not have the physical ability to make up the deficiency due to system capacity limitations or the contractually allowed recoupment period expires. At December 31, 2013 and 2012, we had deferred revenue of approximately $1.6 million and $2.6 million, which is reflected as accrued expenses and other liabilities on our consolidated balance sheets.

Contingent Consideration

We record earn-out provisions related to certain acquisitions at their fair value as of the date of the acquisition. We estimate the fair value of our liability based on the probability-weighted discounted cash flows and estimated production levels of the acquired assets. As additional information becomes available, we adjust the fair value of the earn-out provision and recognize a gain or loss in our statement of income. In connection with the acquisition of the Antero assets, we agreed to pay Antero conditional consideration in the form of potential additional cash payments of up to $40 million, depending on the achievement of certain defined average annual production levels achieved during 2012, 2013 and 2014. During 2012 and 2013, Antero did not meet the annual production level to earn additional payments. Based on our estimates of Antero’s 2014 production, we believe their production levels may exceed the annual production threshold in the earn-out provision and accordingly we have recognized a $31.4 million liability that represents the fair value of the potential payments that may be made under this earn-out provision. Due to the imprecise nature of these projections and assumptions, actual results can and often do, differ from our estimates.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

In order to maintain a cost effective capital structure, it is our policy to borrow funds using a mix of fixed rate debt and variable rate debt. The market risk inherent in our debt instruments is the potential change arising from increases or decreases in interest rates as discussed below.

For fixed rate debt, changes in the interest rates generally affect the fair value of the debt instrument, but not our earnings or cash flows. Conversely, for variable rate debt, changes in interest rates generally do not impact the fair value of the debt instrument, but may affect our future earnings and cash flows.

As of December 31, 2013, the carrying value and fair value of our fixed rate debt instruments (including debt fair value adjustments) was approximately $1,455.9 million and $1,510.4 million, respectively. As of December 31, 2012, the carrying value and fair value of our fixed rate debt instruments was approximately $351.5 million and $365.9 million. For a further discussion of our fixed rate debt, see Part IV, Item 15, Exhibits and Financial Statement Schedules, Note 7.

As of December 31, 2013, we had a $1.0 billion revolving credit facility subject to the risk of loss associated with changes in interest rates. At December 31, 2013, we had obligations totaling $414.9 million under our revolving credit facility. These obligations expose us to the risk of increased interest payments in the event of increases in short-term interest rates. We may hedge portions of our borrowings under our revolver from time to time; however, we did not have any hedging instruments as of December 31, 2013. Floating rate obligations expose us to the risk of increased interest expense in the event of increases in short-term interest rates. If the interest rate on our revolver were to fluctuate by 1% from the rate as of December 31, 2013, our annual interest expense would have changed by a total of $4.1 million.

Commodity Price, Market and Credit Risk

We typically do not take title to the natural gas, NGLs or crude oil that we gather, store, or transport for our customers. However, we do take title to (i) NGLs under certain of our percent-of-proceeds contracts (G&P segment); (ii) crude oil purchased from certain of our Arrow producer customers for our marketing operations (NGL and crude oil segment); and (iii) line pack and base gas that we purchase for our natural gas storage and transportation facilities (storage and transportation segment).  Our current business model is designed to minimize our exposure to fluctuations in commodity prices, although we are willing to assume commodity price risk in certain processing and marketing activities.  We remain subject to volumetric risk under contracts without minimal volume commitments or take-or-pay pricing terms, but absent other market factors that could adversely impact our operations (e.g., market conditions that negatively influence our producer customers decisions to develop or produce hydrocarbons), changes in the price of natural gas, NGLs or crude oil should not materially impact our operations.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As of December 31, 2013, we carried out an evaluation under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer of our General Partner, as to the effectiveness, design and operation of our disclosure controls and procedures (as defined in the Securities Exchange Act of 1934, as amended (Exchange Act) Rules 13a-15(e) and 15d-15(e)). This evaluation considered the various processes carried out under the direction of our disclosure committee in an effort to ensure that information required to be disclosed in the SEC reports we file or submit under the Exchange Act is accurate, complete and timely. Our management, including the Chief Executive Officer and Chief Financial Officer of our General Partner, does not expect that our disclosure controls and procedures or our internal controls will prevent and/or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and our Chief Executive Officer and Chief Financial Officer of our General Partner concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2013.

Changes in Internal Control over Financial Reporting

We completed the Crestwood Merger on October 7, 2013. We have extended our oversight and monitoring processes that support our internal control over financial reporting to include Legacy Inergy’s operations. Except for this extension, we did not make any changes to our internal control over financial reporting during the fourth quarter of 2013 that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, pursuant to Exchange Act Rules 13a-15(f). Our internal control system was designed to provide reasonable assurance to management and our board of directors regarding the preparation and fair presentation of published financial statements in accordance with GAAP.

Management recognizes that there are inherent limitations in the effectiveness of any system of internal control, and accordingly, even effective internal control can provide only reasonable assurance with respect to financial statement preparation and fair presentation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

On November 8, 2013, we acquired Arrow Midstream Holdings, LLC ("Arrow"). Management’s assessment of and conclusion on the effectiveness of internal control over financial reporting excluded Arrow from its assessment and conclusion on the effectiveness of our internal control over financial reporting as of December 31, 2013. The financial reporting systems of Arrow were not integrated into our financial reporting systems throughout 2013. Therefore, we did not have the practical ability to perform an assessment of their internal controls in time for this current year-end. We fully expect to include Arrow in next year’s assessment. Arrow constituted $930.6 million and $218.8 million in total assets and revenues, respectively, in our consolidated financial statements.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we assessed the effectiveness of our internal control over financial reporting as of December 31, 2013. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework. Based upon our assessment, we conclude that, as of December 31, 2013, our internal control over financial reporting is effective, based upon those criteria.

Our independent registered public accounting firm, Ernst & Young LLP, issued an attestation report dated February 28, 2014, on the effectiveness of our internal control over financial reporting, which is included herein.

Item 9B. Other Information.

Independent Directors

Because we are a limited partnership, the listing standards of the NYSE do not require that we or our general partner have a majority of independent directors on the board, nor that we establish or maintain a nominating or compensation committee of the board. We are, however, required to have an audit committee consisting of at least three members, all of whom are required to be independent as defined by the NYSE. The board of directors has determined that Alvin Bledsoe, Warren Gfeller, Philip Gettig and David Lumpkins qualify as independent pursuant to independence standards established by the NYSE as set forth in Section 303A.02 of the manual. To be considered an independent director under the NYSE listing standards, the board of directors must affirmatively determine that a director has no material relationship with us other than as a director. In making this determination, the board of directors adheres to all of the specific tests for independence included in the NYSE listing standards and considers all other facts and circumstances it deems necessary or advisable.

Board Committees

Audit Committee

The members of the audit committee are Alvin Bledsoe, Philip Gettig and David Lumpkins. Our board has determined that each of the members of our audit committee meets the independence standards of the NYSE and is financially literate. In addition, the board has determined that Mr. Bledsoe is an audit committee financial expert based upon the experience stated in his biography. The audit committee's primary responsibilities are to monitor: (a) the integrity of our financial reporting process and internal control system; (b) the independence and performance of the independent registered public accounting firm; and (c) the disclosure controls and procedures established by management. Our audit committee charter may be found on our website at www.crestwoodlp.com.

Compensation Committee

Although we are not required by NYSE listing standards to have a compensation committee, two members of our board of directors also serve as members of our compensation committee, which oversees compensation decisions for the executive officers of Crestwood Equity GP LLC, as well as the compensation plans described below. The members of the compensation committee are David Wood and Warren Gfeller. Our compensation committee charter may be found on our website at www.crestwoodlp.com.

Conflicts Committee

Our general partner has established a conflicts committee to review specific matters which the board of directors believes may involve conflicts of interest. The members of our conflicts committee are Philip Gettig and David Lumpkins. A conflicts committee will determine if the resolution of any conflict of interest submitted to it is fair and reasonable to us. In addition to satisfying certain other requirements, the members of the conflicts committee must meet the independence standards for service on an audit committee of a board of directors, which standards are established by the NYSE. Any matters approved by the conflicts committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders.

64

Board Leadership Structure

The board has no policy that requires that the positions of the Chairman of the Board (the “Chairman”) and the Chief Executive Officer be separate or that they be held by the same individual. The board believes that this determination should be based on circumstances existing from time to time, including the composition, skills and experience of the board and its members, specific challenges faced by us or the industry in which we operate, and governance efficiency. Based on these factors, Robert Phillips serves as our Chairman and Chief Executive Officer.

Risk Oversight

We face a number of risks, including environmental and regulatory risks, and others, such as the impact of competition. Management is responsible for the day-to-day management of risks our company faces, while the board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In fulfilling its risk oversight role, the board of directors must determine whether risk management processes designed and implemented by our management are adequate and functioning as designed. Senior management regularly delivers presentations to the board of directors on strategic matters, operations, risk management and other matters, and is available to address any questions or concerns raised by the board. Specifically, at the February 2014 audit committee meeting, senior management provided a comprehensive risk assessment to the audit committee focused on the key risks facing our company.

Our board committees assist the board in fulfilling its oversight responsibilities in certain areas of risk. The audit committee assists with risk management oversight in the areas of financial reporting, internal controls and compliance with legal and regulatory requirements and our risk management policy relating to our hedging program. The compensation committee assists the board of directors with risk management relating to our compensation policies and programs.

Meetings of Non-Management Directors

Our non-management directors meet in regularly scheduled sessions. Our non-management directors have appointed Warren H. Gfeller as the lead director to preside at such meetings. In addition, our independent directors meet in executive session at least once a year.

Communication with the Board of Directors

We have established a procedure by which unitholders or interested parties may communicate directly with the board of directors, any committee of the board, any of the independent directors or any one director serving on the board of directors by sending written correspondence addressed to the desired person, committee or group to the attention of Joel C. Lambert, Senior Vice President, General Counsel, 700 Louisiana Street, Suite 2060, Houston, TX 77002. Communications are distributed to the board of directors, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communication.

Code of Ethics/Governance Guidelines

We have adopted a Code of Business Conduct and Ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions, as well as to all of our other employees. Additionally, the board of directors has adopted corporate governance guidelines for the directors and the board. The Code of Business Conduct and Ethics and corporate governance guidelines may be found on our website at www.crestwoodlp.com.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our company’s directors and executive officers, and persons who own more than 10% of any class of equity securities of our company registered under Section 12 of the Exchange Act, to file with the Securities and Exchange Commission initial reports of ownership and report of changes in ownership in such securities and other equity securities of our company. Securities and Exchange Commission regulations require directors, executive officers and greater than 10% unitholders to furnish our company with copies of all Section 16(a) reports they file. To our knowledge, based solely on review of the reports furnished to us and written representations that no other reports were required, during the fiscal year ended December 31, 2013, all section 16(a) filing requirements applicable to our directors, executive officers and greater than 10% unitholders, were met.

Item 11. Executive Compensation.

Compensation Discussion and Analysis

All of our executive officers and other personnel necessary for the management of our business are employed and compensated by a subsidiary of Crestwood Equity Partners LP, subject to our reimbursement for services provided to us.

Responsibility and authority for cash compensation-related decisions for our executive officers resides with the compensation committee of the board of directors of Crestwood Equity GP LLC. Our executive officers manage our business as part of the service provided by Crestwood Equity Partners LP under the omnibus agreement, and the cash compensation for all of our executive officers is partially and indirectly paid by us through reimbursement to Crestwood Equity Partners LP. The compensation committee of the board of directors of our general partner is responsible for the administration of our long-term incentive plan and for compensation of our general partner’s non-employee directors.

Certain of our officers devote the majority of their time to our business, while other officers have responsibilities for both us and Crestwood Equity Partners LP and devote less than a majority of their time to our business. Because the officers of our general partner are employees of a subsidiary of Crestwood Equity Partners LP, cash compensation is paid by Crestwood Equity Partners LP and we reimburse Crestwood Equity Partners LP in exchange for the employees’ services provided to us. The officers of our general partner, as well as the employees of Crestwood Equity Partners LP who provide services to us, may participate in employee benefit plans and arrangements sponsored by Crestwood Equity Partners LP and its subsidiaries including plans that may be established in the future.

Compensation Philosophy and Objectives

We do not directly employ any of the persons responsible for managing our business. Our general partner manages our operations and activities, and its board of directors and executive officers will make decisions on our behalf and we have no control over such costs. All of our executive officers also serve as executive officers of Crestwood Equity Partners LP or one of its subsidiaries. We are only responsible for the reimbursement that we pay to Crestwood Equity Partners LP pursuant to the omnibus agreement. However, from time to time the shared executives may receive awards of equity in us pursuant to our long-term incentive plan and we will bear the costs of the awards granted under our long-term incentive plan.

Additional Information

A full discussion of the compensation programs for Crestwood Equity Partners LP’s executive officers and the policies and philosophy of the compensation committee of the board of directors of Crestwood Equity GP LLC is set forth in Crestwood Equity Partners LP’s annual report on Form 10-K under the heading “Executive Compensation.” Specifically, compensation paid directly by us through our long-term incentive plan or indirectly by us through reimbursement pursuant to the Omnibus Agreement is included in the amounts set forth in certain of the tables set forth in Item 11 of Crestwood Equity Partners LP annual report on Form 10-K, with awards outstanding pursuant to our long-term incentive plan separately identified.

Crestwood Midstream Partners LP Long Term Incentive Plan

Our general partner sponsors the Crestwood Midstream Partners LP Long Term Incentive Plan for its directors, consultants and employees and the employees and consultants of its affiliates who perform services for it. The plan is administered by the compensation committee of our general partner’s board of directors.

Restricted Units

The Crestwood Midstream Partners LP Long Term Incentive Plan currently permits, and our general partner has made, grants of restricted units. Restricted units are subject to a restricted period the terms of which are set forth in a restricted unit award agreement. In general, restricted units vest over a three year period. The individual award agreement also sets forth the conditions under which the restricted units may become vested or forfeited, which may include, without limitation, the accelerated vesting upon termination without cause, change in control, the achievement of specified performance goals, or the forfeiture for failing to achieve specified performance goals and such other terms and conditions as the committee may establish. Unless otherwise specifically provided for in an award agreement, distributions are paid to the holder of the restricted units without restriction. Restricted units are designed to furnish additional compensation to employees and directors and to align their economic interests with those of common unitholders. Grants of restricted units pursuant to the Crestwood

66

Midstream Partners LP Long Term Incentive Plan are reflected in the tables contained in Crestwood Equity Partners LP’s annual report on Form 10-K under the heading “Executive Compensation.”

Compensation Committee Report

We have reviewed and discussed the foregoing Compensation Discussion and Analysis with management. Based on our review and discussion with management, we have recommended that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K for the year ended December 31, 2013

Item 13. Certain Relationships, Related Transactions and Director Independence.

For a discussion of director independence, see Item 10 “Directors, Executive Officers and Corporate Governance.”

Prior to June 19, 2013, CEQP owned 56,398,707 of our common units, which equaled an approximate 65.6% limited partner interest in us. On June 19, 2013, CEQP completed a distribution on a pro rata basis to CEQP unitholders of the 56,398,707 common units previously owned by CEQP (the “Spin-Off”). Our general partner (Crestwood Midstream GP LLC) owns a non-economic general partner interest in us. The sole member of our general partner, Crestwood Midstream Holdings LP, owns all of our IDRs.

Following the closing of the Crestwood Merger on October 7, 2013, Crestwood Holdings exchanged 7,100,000 of our common units for 14,300,000 of CEQP common units pursuant to an option granted to Crestwood Holdings when it acquired our general partner.

Distributions and Payments to Our General Partner and Its Affiliates

The table below summarizes the distributions and payments made or to be made by us to our general partner and its affiliates in connection with our ongoing operations. These distributions and payments were determined by and among affiliated entities.

70

Distributions of available cash to our general partner and its affiliates...................................	We will generally make cash distributions 100% to our common unitholders, until each common unit has received the initial quarterly distribution of $0.37. Our general partner will not receive cash distributions on its non-economic general partner interest. If distributions exceed the initial quarterly distribution of $0.37 per unit, CEQP will be entitled to 50% of our cash distributions above the initial quarterly distribution level in respect of its IDRs.
	In 2013, we made approximately $47.1 million of distributions to our general partner and its affiliates as holders of our common units. In 2013, we also paid approximately $12.7 million to our general partner in respect of the IDRs.
Payments to our general partner and its affiliates........	Neither our general partner nor CEQP will receive any management fee or other compensation for the management of our business. However, prior to making any distribution on our common units, we will reimburse our general partner and its affiliates, including CEQP, for all direct and indirect expenses incurred on our behalf, which were approximately $21.9 million in 2013 (including $16.9 million in reimbursements of direct personnel related expenses). Our partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us.
Withdrawal or removal of our general partner..............	If our general partner withdraws or is removed, its general partner interest will either be sold to the new general partner for cash or converted into common units, in each case for an amount equal to the fair market value of those interests.

Omnibus Agreement

We have entered into an omnibus agreement with our general partner, CEQP and its general partner that governs certain aspects of our relationship with them, including:

• the provision by CEQP to us of certain administrative services and our agreement to reimburse CEQP for such services;

• the provision by CEQP of such employees as may be necessary to operate and manage our business, and our agreement to reimburse CEQP for the expenses associated with such employees; and

• certain indemnification obligations.

CEQP’s indemnification obligations to us includes certain liabilities relating to:

• for three years after our initial public offering (“IPO”), certain environmental liabilities attributable to the ownership and operation of our assets prior to our IPO, including (i) any violation or correction of a violation of environmental laws associated with our assets, where a correction of violation would include assessment, investigation, monitoring, remediation, or other similar action and (ii) any event, omission or condition associated with the ownership or operation of our assets (including the presence or release of hazardous materials), including (a) the cost and expense of any assessment, investigation, monitoring, remediation or other similar action, (b) the cost and expense of the preparation and implementation of any closure activity or remedial or corrective action required under environmental laws, and (c) the cost and expense of any environmental or toxic tort litigation;

• environmental liabilities attributable with our prior ownership and operation of Tres Palacios Gas Storage LLC;

• the ownership and operation of our assets prior to the IPO;

provided, that (i) the aggregate amount payable to us pursuant to the first bullet point above will not exceed $15 million and (ii) amounts are only payable to us pursuant to the first and second bullet points above after liabilities relating to the first and second bullet points have exceeded $100,000 and then only for such amounts in excess of $100,000;

• until the first day after the applicable statute of limitations, any of our federal, state and local income tax liabilities attributable to the ownership and operation of our assets prior to our IPO;

71

• for three years after the closing of our IPO, the failure to have all necessary consents and governmental permits where such failure renders us unable to use and operate our assets in substantially the same manner in which they were used and operated immediately prior to our IPO; and

• for three years after the closing of our IPO, our failure to have valid and indefeasible easement rights, rights-of-way, leasehold and/or fee ownership interest in and to the lands on which our assets are located and such failure prevents us from using or operating our assets in substantially the same manner as they were used or operated immediately prior to our IPO.

CEQP will not be required to indemnify us for any claims, losses or expenses or income taxes referred to above to the extent such were either (i) reserved for in our financial statements as of the closing of our IPO or (ii) we recover any such amounts under available insurance coverage, from contractual rights or other recoveries against any third party.

Our indemnification obligations to CEQP, its general partner and their affiliates (other than our general partner, us and our subsidiaries) includes certain liabilities relating to:

• certain environmental liabilities attributable to the ownership and operation of our assets, but only to the extent the violations, events, omissions or conditions giving rise to such covered environmental liabilities occur after the closing of our IPO; provided , that (i) our aggregate liability for such covered environmental liabilities will not exceed $15 million and (ii) amounts are only payable by us pursuant to this bullet point after liabilities relating to such covered environmental losses have exceeded $100,000 and then only for such amounts in excess of $100,000; and

• losses suffered or incurred by CEQP by reason of or arising out of events and conditions associated with the operation of our assets that occur on or after our IPO (other than covered environmental losses, which are covered by the preceding bullet).

With respect to the provision by CEQP of certain administrative services and such management and operating services as may be necessary to manage and operate our business, the omnibus agreement addresses certain aspects of our relationship with CEQP, including:

• the provision by CEQP to us of certain specified administrative services necessary to run our business, including the provision of such employees as may be necessary to operate and manage our business, and our agreement to reimburse CEQP for all reasonable costs and expenses incurred in connection with such services;

• our agreement to reimburse CEQP for all expenses it incurs as a result of us being a publicly traded partnership; and

• our agreement to reimburse CEQP for all expenses that it incurs or payments it makes on our behalf with respect to insurance coverage for our business.

Neither our partnership agreement nor the omnibus agreement will limit the amount of expenses for which our general partner and its affiliates may be reimbursed. However, we expect these services to be provided at cost.

Except for the indemnification provisions, the omnibus agreement may be terminated by CEQP with 180 days’ prior written notice if (i) Crestwood Midstream GP LLC is removed as our general partner under circumstances where “cause” does not exist and the common units held by CEQP and its affiliates were not voted in favor of such removal; (ii) a change of control of CEQP occurs; or (iii) a change of control of us occurs. Except for the indemnification provisions, we may terminate the omnibus agreement with 180 days’ prior written notice if a change of control of CEQP occurs.

During the year ended December 31, 2013, we paid approximately $5.0 million to CEQP pursuant to the omnibus agreement.

Tax Sharing Agreement

We have entered into a tax sharing agreement with CEQP pursuant to which we will reimburse CEQP for our share of state and local income and other taxes borne by CEQP as a result of our income being included in a combined or consolidated tax return filed by CEQP with respect to taxable periods including or beginning on the closing date of our IPO. The amount of any such reimbursement will be limited to the tax that we (and our subsidiaries) would have paid had we not been included in a combined group with CEQP. CEQP may use its tax attributes to cause its combined or consolidated group, of which we may be a member for this purpose, to owe no tax. However, we would nevertheless reimburse CEQP for the tax we would have owed had the attributes not been available or used for our benefit, even though CEQP had no cash expense for that period.

72

Registration Rights Agreement

In connection with the Crestwood Merger, we entered into a registration rights agreement with John J. Sherman, our former president and chief executive officer who currently serves on our board of directors.

Other Transactions with Related Persons

We provide firm storage services utilizing 100% of the operationally available storage capacity at our Bath storage facility to an affiliate, Crestwood Services LLC, under a five-year contract entered into in March 2011. As of December 31, 2013 the annual storage fee was approximately $13.5 million. The terms and conditions of the storage contract are consistent with the terms and conditions of the storage leases that Crestwood Services has entered into with third parties. We received total revenues from Crestwood Services under this contract of $7.2 million for the year ended December 31, 2013.

In addition, we will provide firm storage services utilizing 100% of the operationally available storage capacity at our proposed Watkins Glen NGL storage facility to Crestwood Services under a five-year contract expiring March 31, 2016, subject to Crestwood Services' renewal rights.  All revenue generated by Crestwood Services from subleasing storage capacity to third parties at the storage facility will be paid to us during the term of the contract.  The other terms and conditions of the storage contract are consistent with the terms and conditions of the storage contracts that Crestwood Services enters into with third-party customers. 

Review, Approval or Ratification of Transactions with Related Persons

Although we do not have any formal policy for the review of related party transactions, the Audit Committee would review and approve all transactions or series of related financial transactions, arrangements or relationships between our partnership and any related party, including those that involve an amount that exceeds $120,000.

In addition, pursuant to our Code of Business Conduct and Ethics, our directors and officers are expected to bring to the attention of our Compliance Officer any conflict or potential conflict of interest. If a conflict or potential conflict of interest arises between our partnership and our general partner, the resolution of any such conflict or potential conflict should be addressed by the board in accordance with the provisions of our partnership agreement. At the discretion of the board in light of the circumstances, the resolution may be determined by the board in its entirety or by a conflicts committee meeting the definitional requirements for such a committee under our partnership agreement.

Item 14. Principal Accountant Fees and Services.

Effective as of October 7, 2013, the Audit Committee of the Board (the “Board”) of Directors of Crestwood Midstream GP LLC (f/k/a NRGM GP, LLC) dismissed Deloitte & Touche LLP (“Deloitte”) as the independent registered public accounting firm of Legacy Crestwood and approved the engagement of Ernst & Young LLP (“E&Y”) as the principal accountant to audit the partnership’s financial statements as of and for the fiscal year ending December 31, 2013. Legacy Crestwood is the accounting predecessor to the partnership and its financial statements now constitute the primary financial statements of the partnership.

The audit report on the financial statements of Legacy Crestwood for the fiscal years ended December 31, 2012 and December 31, 2011 issued by Deloitte did not contain any adverse opinion or disclaimer of opinion, nor was the report qualified or modified as to uncertainty, audit scope or accounting principles. Furthermore, during Legacy Crestwood’s two most recent fiscal years ended December 31, 2012 and December 31, 2011 and the subsequent interim period through October 6, 2013, (1) there were no disagreements between Legacy Crestwood and Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference thereto in its report on Legacy Crestwood’s financial statements for such periods, and (2) there were no “reportable events” as that term is described in Item 304(a)(1)(v) of Regulation S-K.

In addition, during Legacy Crestwood’s fiscal years ended December 31, 2012 and 2011 and the subsequent interim period ending October 6, 2013, Legacy Crestwood did not consult E&Y in regards to Legacy Crestwood’s financial statements, which were audited by Deloitte as its independent accountant, with respect to (1) the application of accounting principles to a specified transaction, either completed or proposed and (2) the type of audit opinion that was rendered on Legacy Crestwood’s financial statements or might be rendered on Legacy Crestwood’s financial statements. During such fiscal years and subsequent interim period ending October 6, 2013, Legacy Crestwood did not consult with E&Y in regards to Legacy Crestwood’s financial statements with respect to any matter that was the subject of a “disagreement” or a “reportable event” as those terms are described in Item 304(a)(1) of Regulation S-K.

73

The following table presents fees billed for professional audit services rendered for the audit of our annual financial statements and for other services for the years ended December 31, 2013 and 2012 (in millions):

	Ernst & Young LLP		Deloitte & Touche LLP
	2013		2013		2012

The audit committee of our general partner reviewed and approved all audit and non-audit services provided to us during 2013. For information regarding the audit committee’s pre-approval policies and procedures related to the engagement by us of an independent accountant, see our audit committee charter on our website at www.crestwoodlp.com.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Crestwood Midstream Partners LP (formerly Inergy Midstream, L.P.) at December 31, 2013, and the consolidated results of its operations and its cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Crestwood Midstream Partners LP’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commissions (1992 framework) and our report dated February 28, 2014, expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Unitholders of Crestwood Midstream Partners LP

We have audited the consolidated balance sheet of Crestwood Midstream Partners LP and subsidiaries (the “Partnership”) as of December 31, 2012, and the related consolidated statements of operations, cash flows, and partners’ capital for each of the two years in the period ended December 31, 2012. These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements, present fairly, in all material respects, the financial position of Crestwood Midstream Partners LP and subsidiaries at December 31, 2012, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

The consolidated financial statements give effect to the acquisition of Crestwood Marcellus Midstream LLC by the Partnership on January 8, 2013, which has been accounted for at historical cost as a reorganization of entities under common control as described in Note 9 to the consolidated financial statements.

As discussed in Note 6 to the consolidated financial statements, the 2012 and 2011 consolidated financial statements have been retrospectively adjusted for earnings per unit for the common units issued in connection with the Crestwood Merger, as described in Note 1 to the consolidated financial statements, as if those units issued were outstanding for the entire period prior to the Crestwood Merger.

As discussed in Note 14 to the consolidated financial statements, the 2012 and 2011 consolidated financial statements have been retrospectively adjusted for a change in segments as a result of the Crestwood Merger as described in Note 1 to the consolidated financial statements.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. With respect to the unaudited pro forma information presented in Note 4 to the consolidated financial statements for the acquisitions of Inergy Midstream, L.P. and Arrow Midstream Holdings, LLC, such information has not been subjected to the auditing procedures applied in our audits of the basic financial statements and, accordingly, we express no opinion on them.

Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting

The Board of Directors of Crestwood Midstream GP LLC and Unitholders of Crestwood Midstream Partners LP

We have audited Crestwood Midstream Partners LP’s (formerly Inergy Midstream, L.P.) internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). Crestwood Midstream Partners LP’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Arrow Midstream Holdings, LLC, which is included in the 2013 consolidated financial statements of Crestwood Midstream Partners LP (formerly Inergy Midstream, L.P.) and constituted $930.6 million of total assets as of December 31, 2013, and $218.8 million and $1.7 million of revenues and operating income, respectively, for the year then ended. Our audit of internal control over financial reporting of Crestwood Midstream Partners LP (formerly Inergy Midstream, L.P.) also did not include an evaluation of the internal control over financial reporting of Arrow Midstream Holdings, LLC.

In our opinion, Crestwood Midstream Partners LP maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2013 consolidated financial statements of Crestwood Midstream Partners LP and our report dated February 28, 2014 expressed an unqualified opinion thereon.

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Organization and Description of Business

Organization

Inergy Midstream, LLC was formed in September 2004 by Crestwood Equity Partners LP (formerly Inergy, L.P., “CEQP”) to acquire, develop, own and operate energy midstream assets. In connection with its initial public offering of common units representing limited partnership interests, Inergy Midstream, LLC converted into a Delaware limited partnership and changed its name to Inergy Midstream, L.P. on November 14, 2011. The partnership’s common units began trading on the NYSE on December 16, 2011 under the symbol “NRGM,” and the IPO closed on December 21, 2011. The partnership changed its name and NYSE listing symbol to Crestwood Midstream Partners LP and “CMLP,” respectively, on October 7, 2013 as part of the business combination described below.

As of December 31, 2013, CEQP owns our non-economic general partnership interest, approximately 4% of our common units representing limited partnership interests and 100% of our incentive distribution rights (“IDRs”), which entitle CEQP to receive 50% of all distributions paid to our common unit holders in excess of our initial quarterly distributions of $0.37 per common unit. CEQP is indirectly owned by Crestwood Holdings LLC (“Crestwood Holdings”), which is substantially owned and controlled by First Reserve Management, L.P. (“First Reserve”) and which owns approximately 11% of our common units as of December 31, 2013.

Unless otherwise indicated, references in this report to “we,” “us,” “our,” “ours,” “our company,” the “partnership,” the “Company,” “CMLP,” “Crestwood Midstream” and similar terms refer to either Crestwood Midstream Partners LP itself or Crestwood Midstream Partners LP and its consolidated subsidiaries, as the context requires. Unless otherwise indicated, references to (i) Legacy Crestwood refers to either Crestwood Midstream Partners LP itself or Crestwood Midstream Partners LP and its consolidated subsidiaries prior to the Crestwood Merger (defined below) and (ii) Legacy Inergy refers to either Inergy Midstream, L.P. itself or Inergy Midstream, L.P. and its consolidated subsidiaries prior to the Crestwood Merger.

Business Combination

On May 5, 2013, CEQP and certain of its affiliates entered into a series of definitive agreements with Crestwood Holdings and certain of its affiliates under which, among other things, (i) CEQP agreed to distribute to its common unitholders all of the Legacy Inergy common units owned by CEQP; (ii) Crestwood Holdings agreed to acquire the owner of CEQP’s general partner; (iii) Crestwood Holdings agreed to contribute ownership of Legacy Crestwood’s general partner and IDRs to CEQP in exchange for common and subordinated units of CEQP; and (iv) Legacy Crestwood agreed to merge with and into a subsidiary of Legacy Inergy in a merger in which Legacy Crestwood unitholders received 1.07 Legacy Inergy common units for each Legacy Crestwood common unit they owned and, Legacy Crestwood unitholders (other than Crestwood Holdings) would receive a one-time $34.9 million cash payment at the closing of the Crestwood Merger, or $1.03 per unit.

On June 5, 2013, Legacy Crestwood’s general partner distributed to a wholly-owned subsidiary of Crestwood Holdings approximately 137,105 common units and approximately 21,588 Class D units of Legacy Crestwood, representing all of the Legacy Crestwood common and Class D units held by Legacy Crestwood’s general partner.

On June 18, 2013, CEQP distributed to its unitholders approximately 56.4 million Legacy Inergy common units, representing all of the Legacy Inergy common units held by CEQP.

On June 19, 2013, Crestwood Holdings acquired the owner of CEQP’s general partner and contributed to CEQP ownership of Crestwood Gas Services GP, LLC, which owned 100% of the general partnership interest and IDRs of Legacy Crestwood. Crestwood Holdings and its ultimate parent company, First Reserve, acquired control of CEQP as a result of these transactions. As a result of Crestwood Holding’s acquisition of control of CEQP, Crestwood Holdings acquired control of our general partner and, consequently, the Company on June 19, 2013.

On October 7, 2013, the merger of Legacy Inergy’s wholly-owned subsidiary with and into Legacy Crestwood (the “Crestwood Merger”) was completed, with Legacy Crestwood continuing as the surviving accounting entity. Immediately following the closing of the Crestwood Merger, on October 7, 2013, (i) Legacy Crestwood merged with and into Legacy Inergy, with Legacy Inergy continuing as the surviving legal entity, and (ii) Legacy Inergy changed its name to Crestwood Midstream Partners LP and changed its NYSE listing symbol to “CMLP”. Under the merger agreement, Legacy Crestwood unitholders received 1.07 units of Legacy Inergy units for each unit of Legacy Crestwood they owned and as a result, there were no Legacy Crestwood

common or Class D units outstanding immediately following the merger. Additionally, Legacy Crestwood unitholders (other than Crestwood Holdings) received a one-time $34.9 million cash payment at the closing of the merger, or $1.03 per units, $24.9 million of which was paid by Legacy Inergy and $10 million of which was paid by Crestwood Holdings.

Following the closing of the Crestwood Merger on October 7, 2013, Crestwood Holdings exchanged 7,100,000 of our common units for 14,300,000 of CEQP common units pursuant to an option granted to Crestwood Holdings when it acquired our general partner.

Description of Business

We provide gathering, processing, storage and transportation solutions to customers in the crude oil, NGL and natural gas sectors of the energy industry. Our financial statements reflect three operating and reporting segments: (i) gathering and processing; (ii) NGL and crude services; and (iii) storage and transportation.

Our gathering and processing (G&P) operations provide natural gas gathering, processing, treating, compression and transportation services to producers in unconventional shale plays in West Virginia, Wyoming, Texas, Arkansas, New Mexico and Louisiana. The consolidated and unconsolidated assets reflected in this segment include rich gas gathering systems and processing plants in the Marcellus, Powder River Basin (“PRB”) Niobrara, Barnett, Granite Wash, and Avalon Shale plays, and dry gas gathering systems in the Barnett, Fayetteville, and Haynesville Shale plays.

Our NGL and crude services operations provide gathering, storage and transportation services to producers, refiners, marketers, and other customers. The consolidated assets reflected in this segment primarily include (i) the COLT Hub, a crude oil rail loading and storage terminal located in North Dakota, (ii) the Arrow crude oil, natural gas and water gathering systems located on the Fort Berthold Indian Reservation in North Dakota, (iii) the Bath storage facility, an NGL underground storage facility in New York, and (iv) US Salt, a solution-mining and salt production company in New York.

Our storage and transportation operations provide natural gas storage and transportation services to third parties. The consolidated assets reflected in this segment primarily include natural gas storage facilities in New York (Stagecoach, Thomas Corners, Steuben and Seneca Lake), and natural gas transmission facilities in New York and Pennsylvania (the North-South Facilities, the MARC I Pipeline, and the East Pipeline).

Note 2 – Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements were originally the financial statements of Legacy Crestwood, prior to the Crestwood Merger and the merger of Legacy Crestwood with and into Legacy Inergy on October 7, 2013 as discussed above. Crestwood Holdings acquisition of control of CEQP’s general partner on June 19, 2013 was accounted for as a reverse acquisition under the purchase method of accounting in accordance with accounting standards for business combinations.  The accounting for a reverse merger results in the legal acquiree (Crestwood Gas Services GP LLC) being the acquirer for accounting purposes.  The accounting acquiree (Inergy, inclusive of Inergy Midstream) was subject to the purchase method of accounting and its balance sheet was adjusted to fair market value as of June 19, 2013.  The merger of Legacy Crestwood and Inergy Midstream on October 7, 2013 was accounted for as a reverse merger amongst entities under common control.  Although Legacy Crestwood was the surviving entity for accounting purposes, Inergy Midstream was the surviving entity for legal purposes, and consequently we changed our name from Inergy Midstream, LP to Crestwood Midstream Partners, LP.  As the reverse merger was amongst entities under common control, the financial statements have been recast to reflect the operations of Inergy Midstream as being acquired by Legacy Crestwood on June 19, 2013, the date in which Inergy Midstream and Legacy Crestwood came under common control.  On September 27, 2013, we changed our fiscal year-end from September 30 to December 31 to adopt the fiscal year of Legacy Crestwood.

Our consolidated financial statements are prepared in accordance with GAAP and include the accounts of all consolidated subsidiaries after the elimination of all intercompany accounts and transactions. In management’s opinion, all necessary adjustments to fairly present our results of operation, financial position and cash flows for the periods presented have been made and all such adjustments are of a normal and recurring nature.

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Principles of Consolidation

We consolidate entities when we have the ability to control or direct the operating and financial decisions of the entity or when we have a significant interest in the entity that gives us the ability to direct the activities that are significant to that entity. The determination of our ability to control, direct or exert significant influence over an entity involves the use of judgment. We apply the equity method of accounting where we can exert significant influence over, but do not control or direct the policies, decisions or activities of an entity. We use the cost method of accounting where we are unable to exert significant influence over the entity.

Revenue Recognition

We gather, treat, compress, store, transport and sell various commodities (including crude oil, natural gas, NGLs and water) pursuant to fixed-fee and percent-of-proceeds contracts. We recognize revenues for these services and products when all of the following criteria are met:

• services have been rendered or products delivered or sold;

• persuasive evidence of an exchange arrangement exists;

• the price for services is fixed or determinable; and

• collectability is reasonably assured.

For fixed-fee contracts, we recognize revenues based on the volume of crude oil, natural gas or produced water gathered, processed and treated or compressed, as applicable. For percent-of-proceeds contracts, we recognize revenues based on the value of products sold to third parties.

Sales of crude oil, NGLs and salt are recognized at the time product is shipped or delivered to the customer depending on the sales terms. NGL processing fees are recognized upon delivery of the product. Revenues from the COLT Hub are recognized when the contractual services are provided, such as loading of customer rail cars. Revenues from storage and transportation contracts are recognized during the period in which the storage and transportation services are provided, such as providing storage and transportation services during the period a firm service contract is in place. We record deferred revenue when we receive amounts from our customers but have not met the criteria listed above. At December 31, 2013 and 2012, we had deferred revenue of approximately$1.6 millionand$2.6 million, which is reflected in accrued expenses and other liabilities on our consolidated balance sheets.

Credit Risk and Concentrations

Inherent in our contractual portfolio are certain credit risks. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. We take an active role in managing credit risk and have established control procedures, which are reviewed on an ongoing basis. We attempt to minimize credit risk exposure through credit policies and periodic monitoring procedures as well as through customer deposits, letters of credit and entering into netting agreements that allow for offsetting counterparty receivable and payable balances for certain financial transactions, as deemed appropriate.

For the years ended December 31, 2013, 2012 and 2011, Quicksilver Resources Inc. ("Quicksilver") accounted for approximately 15%, 47% and 64% of our total consolidated revenues. For the years ended December 31, 2013 and 2012, Antero Resources Appalachian Corporation ("Antero") accounted for approximately 10% and 11% of our total consolidated revenues. Revenues from Quicksilver and Antero are reflected in our gathering and processing segment.

No customer accounted for 10% or more of our consolidated accounts receivable at December 31, 2013. At December 31, 2012, Quicksilver and Antero accounted for approximately 48% and 14% of our consolidated accounts receivable.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Inventory

Inventory for our NGL and crude services operations and our storage and transportation operations are stated at the lower of cost or market and are computed predominantly using the average cost method. Legacy Crestwood had no inventory at December 31, 2012.

Shipping and Handling Costs

Shipping and handling costs are recorded as part of cost of product/services sold at the time product is shipped or delivered to the customer.

Property, Plant and Equipment

Property, plant and equipment is recorded at is original cost of construction or, upon acquisition, at the fair value of the assets acquired. For assets we construct, we capitalize direct costs, such as labor and materials, and indirect costs, such as overhead and interest. We capitalize major units of property replacements or improvement and expense minor items. Depreciation is computed by the straight-line method over the estimated useful lives of the assets, as follows:

	Years
Gathering systems and pipelines	20
Facilities and equipment	20-25
Buildings, rights-of-way and easements	20-40
Office furniture and fixtures	5-10
Vehicles	5

We deplete salt deposits included in our property, plant and equipment utilizing the unit of production method.

When we retire property, plant and equipment, we charge accumulated depreciation for the original costs of the assets in addition to the cost to remove, sell or dispose of the assets, less their salvage value.

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such events or changes in circumstances are present, a loss is recognized if the carrying value of the asset is in excess of the sum of the undiscounted cash flows expected to result from the use of the asset and its eventual disposition. An impairment loss is measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. We have not identified any indicators that suggest the carrying amount of an asset may not be recoverable as of December 31, 2013.

Identifiable Intangible Assets

We have recorded certain identifiable intangible assets, including customer accounts, covenants not to compete, trademarks, certain revenue contracts and deferred financing costs. Customer accounts, covenants not to compete, trademarks and certain of our revenue contracts have arisen from acquisitions. We amortize certain of our revenue contracts based on the projected cash flows associated with these contracts. Deferred financing costs represent financing costs incurred in obtaining financing and are being amortized over the term of the related debt using the effective interest method. We recognize acquired intangible assets separately if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed, rented or exchanged, regardless of the acquirer's intent to do so.

93

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Certain intangible assets are amortized on a straight-line basis over their estimated economic lives, as follows:

	Weighted-Average Life (years)
Customer accounts	19
Covenants not to compete	3
Trademarks	5
Deferred financing costs	6

Goodwill

Our goodwill represents consideration paid in excess of the fair value of the identifiable assets acquired in a business combination. We evaluate goodwill for impairment, at a minimum, annually on December 31, or whenever events or changes indicate that it is more likely than not that the fair value of a reporting unit could be less than its carrying amount. This evaluation requires us to compare the fair value of each of our reporting units to its carrying value (including goodwill). If the fair value exceeds the book value of a reporting unit, goodwill of the reporting unit is not considered impaired.

We estimate the fair value of our reporting units based on a number of factors, including the potential value we would receive if we sold the reporting unit, discount rates and projected cash flows. Estimating projected cash flows requires us to make certain assumptions as it relates to future operating performance. When considering operating performance, various factors are considered such as current and changing economic conditions and the commodity price environment, among others. Due to the imprecise nature of these projections and assumptions, actual results can and often do, differ from our estimates. If the growth assumptions embodied in the current year impairment testing prove inaccurate, we could incur an impairment charge.

For the year ended December 31, 2013, we recorded an impairment of goodwill of approximately $4.1 million on our Haynesville/Bossier Shale system as a result of a decrease in anticipated revenues to be generated from those operations due primarily to our inability to renew and extend a significant revenue contract that expired in mid-2013.

Investment in Unconsolidated Affiliates

The FASB's accounting standards related to equity method investments and joint ventures requires entities to periodically review their equity method investments to determine whether current events or circumstances indicate that the carrying value of the equity method investment may be impaired. We evaluate our equity method investments for impairment when there are indicators of impairment. If indicators suggest impairment, we will perform an impairment test to assess whether an adjustment is necessary. The impairment test considers whether the fair value of our equity method investments declined and if any such decline is other than temporary. If a decline in fair value is determined to be other than temporary, the investment's carrying value is written down to fair value. No impairment adjustments were recorded in the year ended December 31, 2013.

Income Taxes

We are a master limited partnership. Partnerships are generally not subject to federal income tax, although publicly-traded partnerships are treated as corporations for federal income tax purposes and therefore are subject to federal income tax, unless the partnership generates at least 90% of its gross income from qualifying sources. If the qualifying income requirement is satisfied, the publicly-traded partnership will be treated as a partnership for federal income tax purposes. We satisfy the qualifying income requirement and are treated as a partnership for federal and state income tax purposes. Our consolidated earnings are included in the federal and state income tax returns of our partners. However, legislation in certain states allows for taxation of partnerships, and as such, certain state taxes have been included in our accompanying financial statements as income taxes due to the nature of the tax in those particular states as discussed below. In addition, federal and state income taxes are provided on the earnings of the subsidiaries incorporated as taxable entities. We are required to recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax basis of assets and liabilities using expected rates in effect for the year in which the differences are expected to reverse.

94

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

We are responsible for the Texas Margin tax computed on the Texas franchise tax return. The margin tax qualifies as an income tax under GAAP, which requires us to recognize the impact of this tax on the temporary differences between the financial statement assets and liabilities and their tax basis attributable to such tax. For the years ended December 31, 2013, 2012 and 2011, there were no temporary differences recognized in our consolidated statements of operations.

Net earnings for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and the financial reporting basis of assets and liabilities and the taxable income allocation requirements under our partnership agreement.

Sales Tax

We account for the collection and remittance of sales tax on a net tax basis. As a result, these amounts are not reflected in the consolidated statements of operations.

Cash and Cash Equivalents

We define cash equivalents as all highly liquid investments with maturities of three months or less when purchased.

Allocation of Expenses

We share common management, operating and administrative and overhead costs with CEQP. CEQP allocated to us $9.5 million of costs for the year ended December 31, 2013. Included in this amount was $4.4 million of unit-based compensation charges. We have an omnibus agreement with CEQP that requires us to reimburse CEQP for all shared costs incurred on its behalf, except for certain unit based compensation costs which are treated as capital transactions. Due to the nature of these shared costs, it is not practicable to estimate what the costs would have been on a stand-alone basis. Accordingly, the accompanying financial statements may not necessarily be indicative of the conditions that would have existed, or the results of operations that would have occurred, if we operated as a stand-alone entity.

Asset Retirement Obligations

An asset retirement obligation ("ARO") is an estimated liability for the cost to retire a tangible asset. We record a liability for legal or contractual obligations to retire our long-lived assets associated with right-of-way contracts we hold and our facilities whether owned or leased. We record a liability in the period the obligation is incurred and estimable. An ARO is initially recorded at its estimated fair value with a corresponding increase to property, plant and equipment. This increase in property, plant and equipment is then depreciated over the useful life of the asset to which that liability relates. An ongoing expense is recognized for changes in the fair value of the liability as a result of the passage of time, which we record as depreciation, amortization and accretion expense on our consolidated statements of operations. The fair value of certain AROs could not be determined as the settlement dates (or range of dates) associated with these assets were not estimable. At December 31, 2013 and 2012, our AROs were reflected in other long-term liabilities on our consolidated balance sheets. See Note 11 for a discussion of our AROs.

Environmental Costs and Other Contingencies

We recognize liabilities for environmental and other contingencies when it has an exposure that indicates it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated. Where the most likely outcome of a contingency can be reasonably estimated, we accrue a liability for that amount. Where the most likely outcome cannot be estimated, a range of potential losses is established and if no one amount in that range is more likely than any other, the low end of range is accrued.

We record liabilities for environmental contingencies at their undiscounted amounts on our consolidated balance sheets as accrued expenses and other liabilities when environmental assessments indicate that remediation efforts are probable and costs can be reasonably estimated. Estimates of our liabilities are based on currently available facts and presently enacted laws and regulations, taking into consideration the likely effects of other societal and economic factors. These estimates are subject to revision in future periods based on actual costs or new circumstances. We capitalize costs that benefit future periods and recognize a current period charge in operating and administrative expenses when clean-up efforts do not benefit future periods.

95

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

We evaluate potential recoveries of amounts from third parties, including insurance coverage, separately from our liability. Recovery is evaluated based on the solvency of the third party, among other factors. When recovery is assured, we record and report an asset separately from the associated liability on our consolidated balance sheet.

Unit-Based Compensation

Unit-based compensation awards are valued at the closing market price of our common units on the date of grant, which reflects the fair value of such awards. For those awards that are settled in cash, the associated liability is remeasured at every balance sheet date through settlement, such that the vested portion of the liability is adjusted to reflect its revised fair value through compensation expense. We generally recognize the expense associated with the award over the vesting period. Prior to the Crestwood Merger, Legacy Crestwood issued phantom units under its Fourth Amended and Restated 2007 Equity Plan ("2007 Equity Plan"). At the time of issuance of these phantom units, management of the general partner of Legacy Crestwood determined whether they were settled in cash or settled in common units. The 2007 Equity Plan was terminated in conjunction with the Crestwood Merger. See Note 10 for a further discussion of our equity plans.

Segment Information

There are certain accounting requirements that establish standards for reporting information about operating segments, as well as related disclosures about products and services, geographic areas and major customers. Further, they define operating segments as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. In determining our operating segments, we examine the way we organize our business internally for making operating decisions and assessing business performance. See Note 14 for disclosures related to our three operating and reporting segments.

Note 4 – Acquisitions

2013 Acquisitions

Crestwood Merger

As described in Note 2, the merger of Legacy Crestwood with and into Legacy Inergy was accounted for as a reverse merger amongst entities under common control. This accounting treatment requires the accounting acquiree (Legacy Inergy) to have its assets and liabilities stated at fair value as well as any other purchase accounting adjustments as of June 19, 2013, the date in which Legacy Crestwood and Legacy Inergy came under common control. The fair value of Legacy Inergy was calculated based on the consolidated enterprise fair value of Legacy Inergy as of June 19, 2013. This consolidated enterprise fair value considered the discounted future cash flows of Legacy Inergy's operations and Legacy Inergy's NYSE-listed stock price, the value of its outstanding senior notes based on quoted market prices for same or similar issuances and the value of its outstanding floating rate debt.

The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the merger date (in millions):

Current assets	$	49.0
Property, plant and equipment	1,677.8
Intangible assets	196.0
Other assets	2.9
Total identifiable assets acquired	1,925.7
Current liabilities	30.8
Long-term debt	745.0
Other long-term liabilities	5.3
Total liabilities assumed	781.1
Net identifiable assets acquired	1,144.6
Goodwill	1,537.7
Net assets acquired	$	2,682.3

Of the $1,537.7 million of goodwill, $601.2 million is reflected in our NGL and crude services segment and $936.5 million is reflected in our storage and transportation segment. Goodwill recognized relates primarily to synergies and new expansion opportunities expected to result from the combination of Legacy Inergy and Legacy Crestwood.  The purchase price allocation has been prepared on a preliminary basis pending receipt of a final valuation report and is subject to material change.

During the year ended December 31, 2013, we recognized $148.6 million of operating revenues and $29.8 million of operating income related to this acquisition.

Arrow Acquisition

On November 8, 2013, we acquired Arrow Midstream Holdings, LLC ("Arrow"), a privately-held midstream company, for approximately $750 million, subject to customary capital expenditure and working capital adjustments of approximately $12.8 million.  The acquisition was consummated by merging one of our wholly-owned subsidiaries with and into Arrow (the “Arrow Acquisition”), with Arrow continuing as the surviving entity and our wholly-owned subsidiary. The base merger consideration consisted of $550 million in cash and 8,826,125 common units issued to the sellers, subject to adjustment for standard working capital provisions.

Arrow, through its wholly-owned subsidiaries, owns and operates substantial crude oil, natural gas and water gathering systems located on the Fort Berthold Indian Reservation in the core of the Bakken Shale in McKenzie and Dunn Counties, North Dakota. Arrow also owns salt water disposal wells and a 23-acre central delivery point with multiple pipeline take-away outlets and a fully-automated truck loading facility.

The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):

Current assets	$	192.3
Property, plant and equipment	399.0
Intangible assets	323.4
Other assets	19.4
Total identifiable assets acquired	934.1
Current liabilities	213.1
Other long-term liabilities	3.7
Total liabilities assumed	216.8
Net identifiable assets acquired	717.3
Goodwill	45.5
Net assets acquired	$	762.8

The $45.5 million of goodwill is reflected in our NGL and crude services segment. Goodwill recognized relates primarily to anticipated operating synergies between the assets acquired and our existing assets. The purchase price allocation has been prepared on a preliminary basis pending receipt of a final valuation report and is subject to material change.

During the year ended December 31, 2013, we recognized $218.8 million of operating revenues and $1.7 million of operating income related to this acquisition.

2012 Acquisitions

Antero Acquisition

On March 26, 2012, Crestwood Marcellus Midstream LLC ("CMM") acquired from Antero gathering assets located in Harrison and Doddridge Counties, West Virginia (the “Antero Acquisition”) for approximately $376.8 million. The acquired assets consisted of a 33-mile low-pressure gathering system that delivers Antero’s Marcellus Shale production to various regional pipeline systems and MarkWest Energy Partners’ Sherwood Gas Processing Plant.

In connection with the Antero Acquisition, we agreed to pay Antero conditional consideration in the form of potential additional cash payments of up to $40 million, depending on the achievement of certain defined average annual production levels achieved during 2012, 2013 and 2014. During 2012 and 2013, Antero did not meet the annual production level to earn additional payments. Based on our estimates of Antero’s 2014 production, we believe their production levels will likely exceed the annual production threshold in the earn-out provision and accordingly, we have recognized a $31.4 million liability as of December 31, 2013 that represents the fair value of the potential payments that may be made under this earn-out provision. We estimated the liability based on the probability-weighted discounted cash flows using a 5.9% discount rate and our estimate of Antero’s production in 2014 (a Level 3 fair value measurement).

Upon the closing of the Antero Acquisition, CMM entered into a 20 year, fixed-fee Gas Gathering and Compression Agreement ("GGA") with Antero. The GGA provided for an area of dedication of approximately 127,000 gross acres, or 104,000 net acres, largely located in the rich gas corridor of the southwestern core of the Marcellus Shale play. Under the GGA, Antero committed to deliver minimum annual throughput volumes to us for a seven year period from January 1, 2012 to January 1, 2019, ranging from an average of 300 MMcf/d in 2012 to an average of 450 MMcf/d in 2018. During the period ended December 31, 2012, Antero delivered less than the minimum annual throughput volumes and at December 31, 2012, we recorded a receivable and

100

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

deferred revenue of approximately $2.6 million due to Antero’s potential ability to recover this amount if Antero’s 2013 throughput volumes exceeded the minimum annual throughput volumes included in the GGA for 2013. In the first quarter of 2013, Antero paid us approximately $2.4 million to satisfy their minimum volume commitment. For the year ended December 31, 2013, Antero's throughput volumes exceeded the 2013 minimum thresholds and was sufficient to recover their 2012 minimum volume shortfall that was previously paid. As a result of Antero's recovery of their 2012 shortfall, we reclassified approximately $2.4 million from deferred revenue to other accounts payable at December 31, 2013 to reflect the amount we owe to Antero. We reflect deferred revenue and other accounts payable as accrued expenses and other liabilities on our consolidated balance sheets. See Note 12 for additional information related to our Antero Acquisition.

Devon Acquisition

On August 24, 2012, we acquired certain gathering and processing assets in the NGL rich gas region of the Barnett Shale (the “Devon Acquisition”) from Devon Energy Corporation (”Devon”). We paid approximately $87.3 million for these assets. During the year ended December 31, 2013, we finalized the purchase price allocation of the assets acquired and liabilities assumed, and as a result, we reduced our depreciation, amortization and accretion expense by approximately $2.2 million.

The final purchase price allocation is as follows (in millions):

Cash	$	87.9
Total purchase price	$	87.9
Purchase price allocation:
Property, plant and equipment	$	88.6
Total assets	88.6
Asset retirement obligation	0.5
Environmental liability	0.2
Total liabilities	0.7
Total	$	87.9

We believe that it is impracticable to present financial information for the acquired assets prior to the acquisition date due to the lack of availability of historical financial information related to the acquired assets, and because the 20-year fixed-fee gathering, processing and compression agreement with Devon has significantly different terms than the historical intercompany relationships between the acquired assets and Devon.

EMAC Acquisition

On December 28, 2012, CMM acquired all of the membership interest of E. Marcellus Asset Company, LLC (“EMAC”) from Enerven Compression, LLC (“Enerven”) for approximately $95.0 million. We financed this acquisition through CMM's credit facility. At the time of acquisition, EMAC’s assets consisted of four compression and dehydration stations located on our gathering systems in Harrison County, West Virginia. These assets provide compression and dehydration services to Antero under a compression services agreement through 2018. Antero has the option to renew the agreement for an additional five years upon expiration of the original agreement.

During the year ended December 31, 2013, we finalized the purchase price allocation of the assets acquired and liabilities assumed, and as a result, we reduced our depreciation, amortization and accretion expense by approximately $0.7 million. In addition, we recognized goodwill of approximately $8.6 million, primarily related to anticipated operating synergies between the assets acquired and our existing assets.

2011 Acquisitions

Las Animas Acquisition

On February 16, 2011, we acquired certain midstream assets in the Avalon Shale trend from a group of independent producers for approximately $5.1 million (the “Las Animas Acquisition”). The acquired assets included approximately 46 miles of natural gas gathering pipeline located in the Morrow/Atoka trend and the Avalon Shale trend in southeastern New Mexico. The pipelines are supported by long-term fixed-fee contracts which include existing Morrow/Atoka production and dedications of approximately 55,000 acres.

During the year ended December 31, 2011, we recognized approximately $4.8 million of operating revenues and $0.1 million of operating income related to this acquisition.

Frontier Gas Acquisition

On April 1, 2011, we acquired certain midstream assets in the Fayetteville Shale and the Granite Wash from Frontier Gas Services, LLC for approximately $344.6 million (the "Frontier Gas Acquisition"). We financed $338.1 million of the purchase price through a combination of equity and debt as described in Note 7 and Note 9.

The acquired Fayetteville assets included approximately 130 miles of high pressure and low pressure gathering pipelines in northwestern Arkansas with capacity of approximately 510 MMcf/d, treating capacity of approximately 165 MMcf/d and approximately 35,000 hp compression (the “Fayetteville System”). The Fayetteville System interconnects with multiple interstate pipelines and is supported by long-term fixed-fee contracts with producers who dedicated to us approximately 100,000 acres in the core of the Fayetteville Shale. These contracts have initial terms that extend through 2020 and include an option, by either party to the contract, to extend the contract through 2025. The acquired Granite Wash assets included a 28-mile pipeline system and a 36 MMcf/d cryogenic processing plant in the Texas Panhandle (the “Granite Wash System”). The Granite Wash System is supported by more than 13,000 dedicated acres and long-term contracts with initial terms extending through 2022.

During the year ended December 31, 2011, we recognized approximately $59.0 million in operating revenues and $5.4 million in operating income related to this acquisition.

Tristate Acquisition

On November 1, 2011, we acquired Tristate Sabine, LLC (“Tristate”) from affiliates of Energy Spectrum Capital, Zwolle Pipeline, LLC and Tristate’s management for approximately $72.4 million. We paid $64.4 million in cash at the closing, and we made a deferred payment of approximately $8.0 million in the fourth quarter of 2012.

At the time of acquisition, the Tristate assets located in Haynesville/Bossier Shale consisted of approximately 60 miles of high pressure and low pressure gathering pipelines with capacity of approximately 100 MMcf/d and treating capacity of approximately 80 MMcf/d (collectively, the “Sabine System”). The Sabine System is supported by long-term, fixed-fee contracts with producers who dedicated approximately 20,000 acres to us. These contracts have various initial terms that extend through 2019 and 2021.

During the year ended December 31, 2011, we recognized approximately $1.9 million in operating revenues and $0.9 million in operating income related to this acquisition.

(a) Basic and diluted net income per limited partner unit for the years ended December 31, 2012 and 2011 were computed based on the number of NRGM common units outstanding plus the number of common units issued by Legacy Inergy to Legacy Crestwood unitholders as part of the Crestwood Merger discussed in Note 1 and the number of units issued in conjunction with the Arrow acquisition. Pro forma shares issued in conjunction with the Rangeland acquisition were also included in 2011.

These amounts have been calculated after applying our accounting policies and adjusting the results of the acquisitions to reflect the depreciation and amortization that would have been charged assuming the preliminary fair value adjustments to property, plant and equipment and intangible assets had been made at the beginning of the respective reporting period. The purchase price allocation for the reverse acquisition of Legacy Inergy and Arrow acquisition has been prepared on a preliminary basis pending final asset valuation and asset rationalization, and changes are expected when additional information becomes available. Accordingly, the purchase accounting adjustments made in connection with the development of the unaudited pro forma are preliminary and subject to change.

Note 5 - Investments in Unconsolidated Affiliates

Jackalope Gas Gathering Services, L.L.C.

On July 19, 2013, Crestwood Niobrara LLC ("Crestwood Niobrara"), our consolidated subsidiary, acquired from RKI Exploration and Production, LLC’s (“RKI”) a 50% ownership interest in Jackalope Gas Gathering Services, L.L.C. (“Jackalope”) for approximately $107.5 million. RKI is a privately-owned, independent exploration and production company in which an affiliate of Crestwood Holdings owns a significant minority ownership interest, and therefore is considered our related party. Access Midstream Partners, L.P. (“Access”) operates and owns the remaining 50% interest in Jackalope. Crestwood Niobrara manages the commercial operations of the Jackalope system, and we account for our investment in Jackalope under the equity method of accounting.

Jackalope is developing a gathering and processing system to serve producers in and around Converse County, Wyoming. The Jackalope system and planned future development are supported by a 20-year gathering and processing agreement with Chesapeake Energy Corporation and RKI under an area of dedication of approximately 311,000 gross acres located in the core of the PRB Niobrara. During the year ended December 31, 2013, Crestwood Niobrara contributed an additional $19.6 million to Jackalope to fund its construction projects.

We have reflected the earnings from our investment in Jackalope in our consolidated statements of income, which includes our share of net earnings based on our ownership interest and other adjustments recorded by us as discussed below. During the year ended December 31, 2013, our share of Jackalope’s net earnings was approximately $1.5 million. As of December 31, 2013, our investment balance in Jackalope exceeded our equity in the underlying net assets of Jackalope by approximately $56.8 million. We amortize and generally assess the recoverability of this amount based on the life of Jackalope’s gathering agreement with Chesapeake and RKI. The amortization is reflected as reduction of our earnings from unconsolidated affiliates, and during the year ended December 31, 2013, we recorded amortization expense of approximately $1.4 million.

Jackalope is required to make quarterly distributions of its available cash to its members based on their respective ownership percentage. During the year ended December 31, 2013, Jackalope did not make any distributions to its members.

Our Jackalope investment is in included in our gathering and processing segment.

Powder River Basin Industrial Complex, LLC

On September 4, 2013, Crestwood Crude Logistics LLC ("Crude Logistics") and Enserco Midstream, LLC formed Powder River Basin Industrial Complex, LLC (“PRBIC”) to construct, own and operate an early-stage crude oil rail terminal located in Douglas County, Wyoming (the “Douglas Facility”). The Douglas Facility, which is located in the emerging PRB Niobrara Shale play, is anchored by a long-term agreement with a major producer for the throughput of crude oil volumes through the terminal. The Douglas Facility was placed into manifest service in August 2013, and unit train service is expected to begin during the first quarter of 2014. Crude Logistics paid approximately $22.5 million to acquire a 50.01% interest in PRBIC and invested approximately $1.9 million in PRBIC in 2013 since acquiring its equity interest. We account for our investment in PRBIC under the equity method of accounting.

Our investment in PRBIC was $24.2 million at December 31, 2013. During the year ended December 31, 2013, our share of PRBIC’s earnings were approximately $(0.2) million. As of December 31, 2013, our investment balance in PRBIC approximated our equity in the underlying net assets of PRBIC.

PRBIC is required to make quarterly distributions of its available cash to its members based on their respective ownership percentage. During the year ended December 31, 2013, PRBIC did not make any distributions to its members.

Our PRBIC investment is in included in our NGL and crude services segment.

Note 6 - Earnings Per Limited Partner Unit

Prior to the Crestwood Merger, net income attributable to Legacy Crestwood was allocated to the general partner and the limited partners in accordance with their respective ownership percentages, after giving effect to incentive distributions earned by the general partner. To the extent cash distributions exceeded net income attributable to Legacy Crestwood, the excess distributions were allocated proportionately to all participating units outstanding based on their respective ownership percentages. As a result of the Crestwood Merger, CEQP, our general partner, owns a non-economic general partner interest in us and 100% of our IDRs. We allocate net income attributable to CMLP to our limited partners after giving effect to the IDRs earned by CEQP.

Basic earnings per unit are calculated using the two-class method. Diluted earnings per unit are computed using the treasury stock method, which considers the impact to net income attributed to CMLP and limited partner units from the potential issuance of limited partner units as discussed below. The weighted average number of units outstanding is calculated based on the presumption that the number of common units issued by Legacy Inergy to Legacy Crestwood unitholders as part of the Crestwood Merger were outstanding for the entire period prior to Crestwood Merger.

The tables below show the (i) allocation of net income attributable to limited partners and the (ii) net income attributable to CMLP per limited partner unit based on the number of basic and diluted limited partner units outstanding for the years ended December 31, 2013, 2012 and 2011 (in millions):

We exclude potentially dilutive securities from the determination of diluted earnings per unit (as well as their related income statement impacts) when their impact on net income attributable to CMLP per limited partner unit is anti-dilutive. During the year ended December 31, 2013, we excluded 1,891,326 preferred security units issued by Crestwood Niobrara from our diluted earnings per unit. There were no units excluded from our dilutive earnings per share as we did not have any anti-dilutive units for the years ended December 31, 2012 and 2011.

General Partner Interest and Incentive Distribution Rights

Prior to the Crestwood Merger, Legacy Crestwood’s general partner was entitled to quarterly distributions equal to its general partner interest. In addition, Legacy Crestwood’s general partner held IDRs in accordance with the Legacy Crestwood Partnership Agreement. These rights paid an increasing percentage, up to a maximum of 50% of the cash they distributed from operating surplus in excess of $0.45 per unit per quarter. The maximum distribution of 50% included distributions paid to the general partner based on its general partner interest and assumed that Legacy Crestwood’s general partner maintained its general partner interest. The maximum distribution of 50% did not include any distributions that the general partner may have received on limited partner units that it owned.

Following the Crestwood Merger, our general partner is not entitled to distributions on its non-economic general partner interest. IDRs are entitled to receive 50% of the cash distributed from operating surplus (as defined in our partnership agreement) in excess of the initial quarterly distribution of $0.37.

CEQP, as the owner of our IDRs, has the right under our partnership agreement to elect to relinquish the right to receive incentive distribution payments based on the initial quarterly distribution and to reset, at a higher level, the quarterly distribution amount (upon which the incentive distribution payments to CEQP would be set). If CEQP elects to reset the quarterly distribution, it will be entitled to receive a number of newly issued Company common units. The number of common units to be issued to CEQP will equal the number of common units that would have entitled the holder to the quarterly cash distribution in the prior quarter equal to the distribution to CEQP on the IDRs in such prior quarter. As the reset election has not been made, no additional units have been issued. For accounting purposes, diluted earnings per unit can be impacted, (even if the reset election has not been made), if the combined impact of issuing the additional units and resetting the cash target distribution is dilutive. Currently, diluted earnings per unit has not been impacted because the combined impact is anti-dilutive.

See Note 9 for a further discussion of the distributions and IDRs paid to the general partner during the three years ended December 31, 2013.

Note 7 - Financial Instruments

Fair Value

We separate the fair values of our financial instruments into three levels (Levels 1, 2 and 3) based on our assessment of the availability of observable market data and the significance of non-observable data used to determine fair value. Our assessment and classification of an instrument within a level can change over time based on the maturity or liquidity of the instruments and would be reflected at the end of the period in which the change occurs. At December 31, 2013 and 2012, there have been no changes to the inputs and valuation techniques used to measure fair value, the types of instruments, or the levels in which they are classified.

As of December 31, 2013 and 2012, the carrying amounts of cash and cash equivalents, accounts receivable and accounts payable represent fair value based on the short-term nature of these instruments. The fair value of our credit facilities approximated their carrying amounts as of December 31, 2013 and 2012 due primarily to the variable nature of the interest rate of the instruments, which is considered a Level 2 fair value measurement. As discussed below, contemporaneously with the closing of the Crestwood Merger on October 7, 2013, we repaid and retired the credit facilities of Legacy Crestwood and CMM with borrowings under the Crestwood Midstream Revolver.

We estimated the fair value of our senior notes (representing a Level 2 fair value measurement) primarily based on quoted market prices for the same or similar issuances. The following table reflects the carrying value and fair value of our senior notes (in millions):

	December 31, 2013				December 31, 2012

The Crestwood Midstream Revolver is available to fund acquisitions, working capital and internal growth projects and for general partnership purposes. The Crestwood Midstream Revolver includes a sub-limit up to $25 million for same-day swing line advances and a sub-limit up to $250 million for letters of credit. Subject to limited exception, the new credit facility is secured by substantially all of the equity interests and assets of our restricted domestic subsidiaries, and is joint and severally guaranteed by substantially all of our restricted domestic subsidiaries.

We borrowed $623.6 million under the Crestwood Midstream Revolver to repay in full and retire the credit facilities of Legacy Crestwood, Legacy Inergy and CMM. At December 31, 2013, the balance outstanding on the Crestwood Midstream Revolver was $414.9 million. Outstanding standby letters of credit under the Crestwood Midstream Revolver amounted to $30.7 million at December 31, 2013. As a result, we had $554.4 million of remaining capacity at December 31, 2013, subject to compliance with any applicable covenants under such facility. The weighted-average interest rate as of December 31, 2013 was 2.745%.

The Crestwood Midstream Revolver contains various covenants and restrictive provisions that limit our ability to, among other things:

• incur additional debt;

• make distributions on or redeem or repurchase units;

• make certain investments and acquisitions;

• incur or permit certain liens to exist;

• enter into certain types of transactions with affiliates;

• merge, consolidate or amalgamate with another company; and

• transfer or otherwise dispose of assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

If we fail to perform our obligations under these and other covenants, the lenders' credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the Crestwood Midstream Revolver could be declared immediately due and payable. The Crestwood Midstream Revolver also has cross default provisions that apply to any other material indebtedness of ours.

Borrowings under the Crestwood Midstream Revolver (other than swing line loans) bear interest at its option at either:

• the Alternate Base Rate, which is defined as the highest of (i) the federal funds rate plus 0.50%; (ii) JP Morgan's prime rate; or (iii) Adjusted LIBOR plus 1%; plus a margin varying from 0.75% to 1.75% depending on our most recent total leverage ratio; or

• Adjusted LIBOR, which is defined as LIBOR plus a margin varying from 1.75% to 2.75% depending on our most recent total leverage ratio.

Swingline loans bear interest at the Alternate Base Rate plus a margin varying from 0.75% to 1.75%. The unused portion of the Crestwood Midstream Revolver is subject to a commitment fee ranging from 0.30% to 0.50% per annum according to our most recent total leverage ratio. Interest on Alternative Base Rate loans is payable quarterly or, if Adjusted LIBOR applies, it may be paid at more frequent intervals.

The Crestwood Midstream Revolver requires maintenance of a consolidated leverage ratio (as defined in its credit agreement) of not more than 5.00 (subject to, at our election, a consolidated net leverage ratio of not more than 5.50 to 1.0 during certain periods following certain material acquisitions as further described in its credit agreement) to 1.0 and an interest coverage ratio (as defined in its credit agreement) of not less than 2.50 to 1.0.

At December 31, 2013, the total funded debt to consolidated EBITDA was approximately 4.90 to 1.0 and consolidated EBITDA to consolidated interest expense was approximately 3.56 to 1.0.

2022 Senior Notes. On October 22, 2013, we launched a private placement of $600 million in aggregate principal amount of new 6.125% senior notes due 2022 (the "2022 Senior Notes") in a private offering exempt from the registration requirements of the Securities Act of 1933.  At December 31, 2013, the balance outstanding on the 2022 Senior Notes was $600 million. The notes are guaranteed on a senior unsecured basis by all of our domestic restricted subsidiaries (other than Finance Corp.), subject to certain exceptions.  We used the net offering proceeds to fund a portion of the consideration paid in the Arrow Acquisition and to pay related fees and expenses, and to repay borrowings under the Crestwood Midstream Revolver.

Note 8 - Income Taxes

No provision for federal or state income taxes is included in our results of operations as such income is taxable directly to the partners. Accordingly, each partner is responsible for its share of federal and state income tax. Net earnings for financial statement purposes may differ significantly from taxable income reportable to each partner as a result of differences between the tax basis and financial reporting basis of assets and liabilities.

We are responsible for the Texas Margin tax computed on the Texas franchise tax return. The margin tax qualifies as an income tax under GAAP, which requires us to recognize the impact of this tax on the temporary differences between the financial statement assets and liabilities and their tax basis attributable to such tax. For the years ended December 31, 2013, 2012 and 2011, there were no temporary differences recognized in our consolidated statements of operations.

Uncertain Tax Positions.We evaluate the uncertainty in tax positions taken or expected to be taken in the course of preparing our consolidated financial statements to determine whether the tax positions are more likely than not of being sustained by the applicable tax authority. Tax positions with respect to tax at the partnership level deemed not to meet the more likely than not threshold would be recorded as a tax benefit or expense in the current year. We believe that there are no uncertain tax positions that would impact our operations for the years ended December 31, 2013, 2012 and 2011 and that no provision for income tax is required for these consolidated financial statements. However, our conclusions regarding the evaluation are subject to review and may change based on factors including, but not limited to, ongoing analyses of tax laws, regulations and interpretations thereof.

During 2011 and 2013, Legacy Crestwood issued Class C and Class D units, respectively, representing limited partner units. Legacy Crestwood had the option to pay distributions to its Class C and Class D unitholders with cash or by issuing additional paid-in-kind units based upon the volume common unit weighted-average price for 10 trading days immediately preceding the date the distribution was declared. On April 1, 2013, the outstanding Legacy Crestwood Class C units converted to common units on a one-for-one basis. In conjunction with the Crestwood Merger, Legacy Crestwood unitholders received 1.07 units of Legacy Inergy units for each unit of Legacy Crestwood they owned and as a result, there were no common or Class D units outstanding immediately following the Crestwood Merger. During 2013, Legacy Crestwood issued 183,995 and 292,660 additional Class C and Class D units in lieu of paying a quarterly cash distribution. For the years ended December 31, 2012 and 2011, Legacy Crestwood issued 633,084 and 473,731 additional Class C units in lieu of paying quarterly cash distributions.

Contributions

During 2012, Legacy Crestwood's general partner made additional capital contributions of approximately $5.9 million in exchange for the issuance of an additional 215,722 general partner units. During 2011, the Legacy Crestwood general partner made an additional capital contribution of approximately $8.7 million in exchange for the issuance of an additional 293,948 general partner units.

Distributions

Prior to the Crestwood Merger, Legacy Crestwood’s Second Amended and Restated Agreement of Limited Partnership, dated February 19, 2008, as amended ("Legacy Crestwood Partnership Agreement"), required that, within 45 days after the end of each quarter, they distribute all of their available cash (as defined therein) to unitholders of record on the applicable record date, as determined by its general partner. Legacy Crestwood’s minimum quarterly distribution was $0.30 per unit, to the extent they had sufficient cash flows from operations after the establishment of cash reserve and payment of fees and expenses, including payments to its general partner.

Following the Crestwood Merger, our partnership agreement requires us to distribute, within 45 days after the end of each quarter, all available cash (as defined in our partnership agreement) to common unitholders of record on the applicable record date. The general partner is not be entitled to distributions on its non-economic general partner interest.

Distributions to General Partner

During the years ended December 31, 2013 and 2012, the general partner received cash distributions (representing IDRs and distributions related to general partner units held) of approximately $26.2 million and $25.8 million.

Other Partners' Capital Transactions

Crestwood Merger

As discussed in Note 1, in conjunction with the Crestwood Merger, Legacy Crestwood unitholders received 1.07 units of Legacy Inergy units for each Legacy Crestwood unit they owned and as a result, there were no Legacy Crestwood common or Class D units outstanding immediately following the merger. In addition, Legacy Crestwood unitholders also received a $34.9 million distribution, $10 million of which was funded as a non-cash contribution from Crestwood Holdings and is reflected on our consolidated statements of partners’ capital as contributions from general partner for the year ended December 31, 2013. We reflected the distribution of $34.9 million as distributions to partners on our consolidated statements of partners’ capital for the year ended December 31, 2013.

Acquisitions and Other

CMM. In February 2012, Legacy Crestwood and Crestwood Holdings formed the CMM joint venture. Legacy Crestwood contributed approximately $131.3 million for a 35% membership interest and Crestwood Holdings contributed approximately $243.8 million for a 65% membership interest. On January 8, 2013, Legacy Crestwood acquired Crestwood Holdings’ 65% membership interest in CMM for approximately $258.0 million, which was funded through $129.0 million of borrowings under the Legacy Crestwood credit facility, the issuance of 6,190,469 Class D units and the issuance of 133,060 general partner units to the Legacy Crestwood general partner. As a result of the acquisition of the additional membership interest, Legacy Crestwood had the ability to control CMM’s operating and financial decisions and policies. The transaction was accounted for as a reorganization of entities under common control and accordingly, the historical results of Legacy Crestwood were retrospectively adjusted to reflect the change in reporting entity as of and for the year ended December 31, 2012. We reflected the $243.8 million contribution by Crestwood Holdings as a contribution from partners in our consolidated statements of cash flows and statements of partners’ capital for the year ended December 31, 2012. The issuances of the Class D and general

partner units in conjunction with the acquisition of the additional interest in CMM were reflected as distributions for additional interest in Crestwood Marcellus Midstream LLC in our consolidated statements of cash flows and statements of partners’ capital for the year ended December 31, 2013.

Arrow. On November 7, 2013, we issued 8,826,125 common units as partial consideration of the Arrow Acquisition. See Note 4 for additional information regarding the Arrow Acquisition.

Other. During the year ended December 31, 2013, we received a contribution of approximately $5.5 million related to reimbursements of costs pursuant to our omnibus agreement with CEQP.

Preferred Equity of Subsidiary

In conjunction with the Jackalope Acquisition discussed in Note 5, Crestwood Niobrara issued a preferred interest of approximately $80.6 million to a subsidiary of General Electric Capital Corporation and GE Structured Finance, Inc. (collectively, “GE”). The preferred interest is reflected as non-controlling interest in our consolidated financial statements. During the year ended December 31, 2013, we allocated approximately $4.9 million of net income to the non-controlling interest, which was based on the overall return attributable to the preferred security.

Crestwood Niobrara will fund 75% of future capital contributions to Jackalope through additional preferred interest issuances to GE (up to a maximum of an additional $53.9 million), with the remainder to be funded through our capital contributions to Crestwood Niobrara. During the year ended December 31, 2013, GE contributed approximately $96.1 million (which consisted of the initial contribution of $80.6 million and additional capital contributions of approximately $15.5 million) to Crestwood Niobrara in exchange for an equivalent number of preferred units. The proceeds from GE’s initial contribution were used to fund a portion of the Jackalope acquisition price, and the proceeds from the subsequent contributions were used to fund capital contributions to the Jackalope investment.

Crestwood Niobrara has the option to pay distributions to GE with cash or by issuing additional preferred units through the January 2015 distribution. On October 30, 2013, Crestwood Niobrara issued GE approximately 2,161,657 units in lieu of paying a cash distribution. We serve as the managing member of Crestwood Niobrara and, subject to certain restrictions, we have the ability to redeem GE’s preferred interest in either cash or our common units. On January 31, 2014, Crestwood Niobrara issued 2,210,294 preferred units to GE in lieu of paying a cash distribution.

Note 10 - Equity Plan

Legacy Inergy

Long-Term Incentive Plan

Legacy Inergy's general partner sponsored a long-term incentive plan for its employees, consultants and directors and the employees of its affiliates that performed services for Legacy Inergy. Restricted units were the only type of unvested award outstanding at the time of the Crestwood Merger on June 19, 2013. In conjunction with the Crestwood Merger, the restricted units outstanding under the long-term incentive plan were modified to accelerate the vesting of all the outstanding awards on the earlier of their original vesting date, or either December 31, 2013 or June 19, 2014, depending on the respective employee. We continue to maintain and sponsor this plan.

During the period June 19, 2013 to December 31, 2013, 230,384 restricted units vested at a per unit price of $22.16. Total compensation expense associated with vested and unvested awards amounted to $4.9 million for the year ended December 31, 2013. At December 31, 2013, there were 195,250 unvested restricted units outstanding at a per unit price of $22.16 and total unrecognized compensation expense associated with these restricted units amounted to $1.8 million. That cost is expected to be recognized over the period January 1, 2014 to June 19, 2014.

Legacy Crestwood

Long-Term Incentive Plan

Prior to the Crestwood Merger, awards of phantom and restricted units were granted under Legacy Crestwood's 2007 Equity Plan (the "2007 Equity Plan"). We terminated the 2007 Equity Plan in conjunction with the Crestwood Merger. All unvested phantom and restricted units awarded under the plan vested upon consummation of the Crestwood Merger and all unamortized compensation expense related to those units was recognized on that date. The following table summarizes information regarding phantom and restricted unit activity:

	Payable In Cash				Payable In Units
	Units		Weighted- Average Grant Date Fair Value		Units		Weighted- Average Grant Date Fair Value

Unvested - December 31, 2013	—		$	—	—		$	—

As discussed above, the vesting period of our phantom and restricted units were accelerated upon consummation of the Crestwood Merger.  We recognized compensation expense under the 2007 Equity Plan of approximately $6.5 million, $1.9 million and $0.9 million for the years ended December 31, 2013, 2012 and 2011, included in operating expenses on our consolidated statements of income. We granted phantom and restricted units under the 2007 Equity Plan with a grant date fair value of approximately $4.6 million, $4.7 million and $0.8 million for the years ended December 31, 2013, 2012 and 2011. 

Under the 2007 Equity Plan, participants who were granted restricted units could elect to have us withhold common units to satisfy minimum statutory tax withholding obligations arising in connection with the vesting of non-vested common units. Any such common units withheld were returned to the 2007 Equity Plan on the applicable vesting dates, which corresponded to the times at which income was recognized by the employee. When we withhold these common units, we were required to remit to the appropriate taxing authorities the fair value of the units withheld as of the vesting date. The number of units withheld was determined based on the closing price per common unit as reported on the NYSE on such dates. For the years ended December 31, 2013 and 2012, we withheld 21,014 and 1,405 common units to satisfy employee tax withholding obligations. There were no common units withheld to satisfy employee tax withholding obligations for the year ended December 31, 2011.

Note 11 - Asset Retirement Obligations

We have legal obligations associated with right-of-way contracts we hold and at our facilities whether owned or leased. Where we can reasonably estimate the asset retirement obligation, we accrue a liability based on an estimate of the timing and amount of settlement. We record changes in these estimates based on changes in the expected amount and timing of payments to settle our obligations.

(Case No. 4:13-cv-01763, June 17, 2013), and one in the Delaware Court of Chancery: Hawley v. Crestwood Midstream Partners LP, et al. (Case No. 8689-VCL, filed June 27, 2013). All the cases named Legacy Crestwood (since merged with the Company), Crestwood Gas Services GP LLC, Crestwood Holdings LLC, the current and former directors of Crestwood Gas Services GP LLC, CEQP, the Company, Crestwood Midstream GP LLC (formerly NRGM GP, LLC), and Intrepid Merger Sub, LLC as defendants. All of the suits were brought by purported holders of common units of Legacy Crestwood, both individually and on behalf of a putative class consisting of holders of common units of Legacy Crestwood. The lawsuits generally alleged, among other things, that the directors of Crestwood Gas Services GP LLC breached their fiduciary duties to holders of common units of Legacy Crestwood by agreeing to a transaction with inadequate consideration and unfair terms and pursuant to an inadequate process. The lawsuits further alleged that CEQP, the Company, Crestwood Midstream GP LLC, and Intrepid Merger Sub, LLC aided and abetted the Legacy Crestwood directors in the alleged breach of their fiduciary duties. The lawsuits sought, in general, (i) injunctive relief enjoining the merger, (ii) in the event the merger is consummated, rescission or an award of rescissory damages, (iii) an award of plaintiffs’ costs, including reasonable attorneys’ and experts’ fees, (iv) the accounting by the defendants to plaintiffs for all damages caused by the defendants, and (v) such further equitable relief as the court deems just and proper. The four federal actions also asserted claims of inadequate disclosure under Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, and the Elliot case also named Citigroup Global Markets Inc. as an alleged aider and abettor. The plaintiff in the Hawley action in Delaware filed a motion for expedited proceedings but subsequently withdrew that motion and then filed a stipulation voluntarily dismissing the action without prejudice, which has been granted by the Court, such that the Hawley action has now been dismissed. The plaintiff in the Elliot action filed a motion for expedited discovery, which was denied by the Court. The plaintiffs in the Knoll, Podell, Cooper, and Elliot actions filed an unopposed motion to consolidate these four cases, which the Court granted and captioned the consolidated matter as In re Crestwood Midstream Partners Unitholder Litigation, Lead Case No. 4:13-cv-01528 (the “Consolidated Action”). The plaintiffs entered into a Memorandum of Understanding (MOU) on September 24, 2013 to settle the Consolidated Action whereby the defendants denied liability. The settlement contemplated by the MOU is subject to a number of conditions, including notice to the class and final court approval following completion of a settlement hearing, which is scheduled for May 16, 2014. The defendants expect the Court to approve the final settlement. The anticipated settlement of the MOU will not have a material impact to our consolidated financial statements.

Letter of Intent. In June 2010, Legacy Inergy and Central New York Oil And Gas Company, L.L.C. (“CNYOG”) entered into a letter of intent with Anadarko Petroleum Corporation (“Anadarko”) which contemplated that, subject to certain conditions, Anadarko may exercise an option to acquire up to a 25% ownership interest in the MARC I pipeline. On September 23, 2011, Anadarko filed a complaint against Legacy Inergy and CNYOG in the Court of Common Pleas in Lycoming County,

CRESTWOOD MIDSTREAM PARTNERS LP (FORMERLY INERGY MIDSTREAM, L.P.)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Pennsylvania (Cause No. 11-01697) alleging that (i) Anadarko had an option to acquire, and timely exercised its option to acquire, a 25% ownership interest in the MARC I pipeline, (ii) Legacy Inergy refused to enter into definitive agreements under which Anadarko would acquire a 25% interest in the pipeline and, by doing so, Legacy Inergy breached the letter of intent, and (iii) by refusing to enter into definitive agreements, Legacy Inergy breached a duty of good faith and fair dealing in connection with the letter of intent. Based on these allegations, Anadarko sought various remedies, including specific performance of the letter of intent and monetary damages.   

On September 9, 2013, Legacy Inergy and Anadarko entered into a confidential settlement agreement to resolve any and all claims relating to the litigation. CEQP has reimbursed us for the amount paid to Anadarko under the settlement agreement pursuant to the omnibus agreement that governs our relationship with CEQP.

We are periodically involved in litigation proceedings. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, then we accrue the estimated amount. The results of litigation proceedings cannot be predicted with certainty; however, management believes that we do not have material potential liability in connection with these proceedings that would have a significant financial impact on its consolidated financial condition, results of operations or cash flows. However, we could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid and/or accrued. As of December 31, 2013 and 2012, we had less than $0.1 million accrued for our outstanding legal matters.

Any loss estimates are inherently subjective, based on currently available information, and are subject to management's judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal proceedings, actual results may differ materially from any amounts that have been accrued.

Regulatory Compliance

In the ordinary course of our business, we are subject to various laws and regulations. In the opinion of our management, compliance with current laws and regulations will not have a material effect on our results of operations, cash flows or financial condition.

Environmental Compliance

Our operations are subject to stringent and complex laws and regulations pertaining to health, safety, and the environment. We are subject to laws and regulations at the federal, state and local levels that relate to air and water quality, hazardous and solid waste management and disposal and other environmental matters. The cost of planning, designing, constructing and operating our facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures. Our accruals for environmental matters were immaterial at December 31, 2013 and 2012.

Self-Insurance

We utilize third-party insurance subject to varying retention levels of self-insurance, which management considers prudent.

Contingent Consideration - Antero

In connection with the Antero Acquisition, we agreed to pay Antero conditional consideration in the form of potential additional cash payments of up to $40 million, depending on the achievement of certain defined average annual production levels achieved during 2012, 2013 and 2014. During 2012 and 2013, Antero did not meet the annual production level to earn additional payments. Based on our estimates of Antero’s 2014 production, we believe their production levels will likely exceed the annual production threshold in the earn-out provision and accordingly, we have recognized a $31.4 million liability as of December 31, 2013 that represents the fair value of the potential payments that may be made under this earn-out provision. We estimated the liability based on the probability-weighted discounted cash flows using a 5.9% discount rate and our estimate of Antero’s production in 2014 (a Level 3 fair value measurement).

Commitments and Purchase Obligations

Operating Leases. We maintain operating leases in the ordinary course of our business activities. These leases include those for office buildings and other operating facilities and equipment. The terms of the agreements vary from 2014 until 2032.

Future minimum lease payments under noncancelable operating leases for the next five years ending December 31 and in total thereafter consist of the following (in millions):

Year Ending December 31,
2014	$	2.1
2015	1.7
2016	1.1

Rent expense for operating leases for the years ended December 31, 2013, 2012 and 2011, totaled $7.6 million, $7.4 million and $7.7 million.

Capital Leases.We have a compressor, treating facility and certain auto leases which are accounted for as capital leases. The terms of the agreements vary from 2014 until 2018. We recorded amortization of expense of approximately $3.6 million, $3.1 million and $1.9 million for the years ended December 31, 2013, 2012 and 2011.

Future minimum lease payments related to our capital leases at December 31, 2013 are as follows (in millions):

Our capital lease liabilities were $4.7 million and $7.0 million at December 31, 2013 and 2012 and are included in accrued expenses and other liabilities and other long-term liabilities on our consolidated balance sheets.

Purchase Commitments. We have entered into certain purchase commitments in connection with the identified growth projects primarily related to the Watkins Glen NGL development project, the COLT Hub expansion project, and certain upgrades to the US Salt facility. The Watkins Glen NGL development project entails the conversion of certain caverns created by US Salt into 2.1 million barrels of NGL storage.  The COLT Hub expansion project primarily includes an expansion of receiving, storage, and take-away capacity via interconnecting pipelines, storage tanks, and rail facilities. At December 31, 2013, the total of our storage and transportation and NGL and crude services operations' firm purchase commitments was approximately $48.0 million. The gathering and processing segment also has purchase commitments of approximately $47.7 million primarily related to the expansion of our compression facilities in the Marcellus Shale and other growth and maintenance contractual purchase obligations. The majority of the purchases associated with these commitments are expected to occur over the course of the next twelve months.

Note 13 - Related Party Transactions

Our general partner is owned by CEQP. Affiliates of Crestwood Holdings and its owners, such as Sabine Oil and Gas LLC and Mountaineer Keystone, LLC, are considered our related parties. Concurrent with the Crestwood Merger described in Note 1, Quicksilver is no longer a related party, and as a result our transactions with Quicksilver are now considered non-affiliated transactions.

We enter into transactions with our affiliates within the ordinary course of business and the services are based on the same terms as non-affiliates, including gas gathering and processing services under long-term contracts, product purchases and various operating agreements.

We do not have any employees. Prior to the Crestwood Merger, we were managed and operated by the directors and officers of Legacy Crestwood’s general partner. We had an omnibus agreement with Crestwood Holdings and the Legacy Crestwood general partner under which Legacy Crestwood reimbursed Crestwood Holdings for the provision of various general and administrative services for its benefit and for direct expenses incurred by Crestwood Holdings on its behalf. Crestwood Holdings billed Legacy Crestwood directly for certain general and administrative costs and allocated a portion of its general and administrative costs to Legacy Crestwood. Concurrent with the Crestwood Merger, we have an Omnibus Agreement with CEQP that requires us to reimburse CEQP for all shared costs incurred on its behalf, except for certain unit based compensation which are treated as capital transactions.

The following table shows revenues, cost of goods sold, operating and administrative expenses and reimbursements from our affiliates for the years December 31, 2013, 2012 and 2011 (in millions):

	Year Ended December 31,
	2013		2012		2011

Accounts receivable	$	1.1	$	23.8
Accounts payable	$	3.3	$	3.1
Accrued expenses and other liabilities	$	5.4	$	—

Following the closing of the Crestwood Merger on October 7, 2013, Crestwood Holdings exchanged 7,100,000 of our common units for 14,300,000 of CEQP common units pursuant to an option granted to Crestwood Holdings when it acquired our general partner.

Note 14 - Segments

In conjunction with the Crestwood Merger described in Note 1, we modified our segments and now our financial statements reflect three operating and reporting segments; (i) gathering and processing operations; (ii) NGL and crude services operations; and (iii) storage and transportation operations. Our gathering and processing operations engage in the gathering, processing, treating, compression, transportation and sales of natural gas and the delivery of NGLs. Our NGL and crude services operations provide gathering, storage and transportation services to producers, refiners, marketers, and others that effectively provide flow assurances to our customers, as well as the production and sale of salt products. Our storage and transportation operations provide natural gas storage and transportations services to third parties. Our corporate operations include all general and administrative expenses that are not allocated to the reportable segments. We assess the performance of our operating segments based on EBITDA, which represents operating income plus depreciation, amortization and accretion expense.

Note 15 – Condensed Consolidating Financial Information

We are a holding company and own no operating assets and have no significant operations independent of our subsidiaries. Obligations under our outstanding senior notes and Crestwood Midstream Revolver are jointly and severally guaranteed by substantially all of our restricted domestic subsidiaries, except for Crestwood Niobrara and Crestwood Crude Logistics LLC (Non-Guarantor Subsidiaries). Finance Corp, the co-issuer, is our 100% owned subsidiary and has no material assets, operations, revenues or cash flows other than those related to its service as co-issuer of our senior notes. 

The tables below present condensed consolidating financial statements for us (parent) on a stand-alone, unconsolidated basis, and our combined guarantor and combined non-guarantor subsidiaries as of and for the year ended December 31, 2013.  As discussed in Note 2, the Crestwood Merger was accounted for as a reverse merger between entities under common control, and as such, changes in the composition of guarantors and non-guarantors should be reflected retrospectively based on the guarantor structure that existed as of the end of the most recent balance sheet.  Accordingly, we have not reflected condensed consolidating financial information as of and for the years ended December 31, 2012 or 2011 because our unrestricted subsidiaries were not formed or were not designated as unrestricted subsidiaries as of December 31, 2012 and 2011.
