Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Organization and Basis of Presentation Western Refining Logistics, LP ("WNRL" or the "Partnership") is a Delaware limited partnership formed in July 2013 by Western Refining Logistics GP, LLC ("WRGP" or the "General Partner"), our general partner. WRGP is owned 100% by Western Refining, Inc. ("Western") and holds all of the non-economic general partner interests in WNRL. On October 16, 2013, we completed our initial public offering (the "Offering") of 15,812,500 common units representing limited partner interests. In exchange for the assets contributed, Western received 6,998,500 common units and 22,811,000 subordinated units, all of WNRL's incentive distribution rights and an aggregate cash distribution of $244.9 million to certain of Western's wholly-owned subsidiaries. WNRL is principally a fee-based growth-oriented partnership that was formed to own, operate, develop and acquire logistics and related assets and businesses to include terminals, storage tanks, pipelines and other logistics assets related to the terminalling, transportation, storage and distribution of crude oil and refined products. WNRL's assets include 705 miles of pipelines, approximately 12.4 million barrels of active storage capacity, distribution of wholesale petroleum products and crude oil trucking. On November 16, 2016, Western entered into an Agreement and Plan of Merger (the “Tesoro Merger Agreement”) with Tesoro Corporation, a Delaware corporation (“Tesoro”), Tahoe Merger Sub 1, Inc., a Delaware corporation and wholly-owned subsidiary of Tesoro (“Merger Sub 1”), and Tahoe Merger Sub 2, LLC, a Delaware limited liability company and wholly owned subsidiary of Tesoro ("Merger Sub 2"), pursuant to which Merger Sub 1 will merge with and into Western (the “First Tesoro Merger,” and, if a second merger election as discussed below is not made, the “Tesoro Merger”), with Western surviving the First Tesoro Merger as a wholly-owned subsidiary of Tesoro. The Tesoro Merger Agreement permits either Western or Tesoro, for tax considerations, to require the surviving corporation of the First Tesoro Merger be merged with and into Merger Sub 2 immediately following the effective time of the First Tesoro Merger, with Merger Sub 2 being the surviving company from the second merger (the “Second Tesoro Merger,” and if the second merger election is made, collectively with the First Tesoro Merger, the “Tesoro Merger”). We will continue as a public entity and our debt will remain outstanding following the completion of the Tesoro Merger. On September 15, 2016, WNRL acquired certain terminalling, transportation and storage assets from a wholly-owned subsidiary of Western consisting of the Cottage Grove tank farm and certain terminals, storage assets, pipelines and other logistics assets located at Western's St. Paul Park refinery ("St. Paul Park Logistics Assets"). The St. Paul Park Logistics Assets primarily receive, store and distribute crude oil, feedstock and refined products associated with Western's St. Paul Park refinery. We acquired the St. Paul Park Logistics Assets from Western in exchange for $195 million in cash and 628,224 common units representing limited partner interests in WNRL. We refer to this transaction as the "St. Paul Park Logistics Transaction." This transaction was between entities under common control. See Note 3, Acquisitions, for further discussion. On October 30, 2015, WNRL acquired a segment of the TexNew Mex Pipeline system from Western that currently extends from our crude oil station in Star Lake, New Mexico, in the Four Corners region to our T station in Eddy County, New Mexico (the "TexNew Mex Pipeline System"). We also acquired an 80,000 barrel crude oil storage tank located at our crude oil pumping station in Star Lake, New Mexico and certain other related assets ("TexNew Mex Pipeline Acquisition"). We acquired these assets in exchange for $170 million in cash, 421,031 common units representing limited partner interests in WNRL and 80,000 units of a newly created class of limited partner interests in WNRL, referred to as the "TexNew Mex Units." This purchase was between entities under common control. See Note 3, Acquisitions, for further discussion. On October 15, 2014, WNRL purchased from Western all of the outstanding limited liability company interests of Western Refining Wholesale, LLC ("WRW") for $320 million in cash and 1,160,092 common units (the "Wholesale Acquisition"). This purchase transferred substantially all of WRW's operations from Western to WNRL, constituting the purchase of a business between entities under common control. See Note 3, Acquisitions, for further discussion. The financial statements presented in this Annual Report on Form 10-K have been retrospectively adjusted to include the combined financial results of the St. Paul Park Logistics Assets prior to September 15, 2016, the TexNew Mex Pipeline System prior to October 30, 2015 and the WRW assets prior to October 15, 2014. The historical operations of the St. Paul Park Logistics Assets prior to the St. Paul Park Logistics Transaction generally recorded operating costs and other expenses associated with storage and terminalling services and recorded no revenue.
