14. COMMITMENTS AND CONTINGENCIES

Environmental obligations. WGP, through its partnership interest in WES, is subject to various environmental-remediation obligations arising from federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal and other environmental matters. As of December 31, 2014 and 2013, asset retirement obligations and other on the consolidated balance sheets included $1.5 million and $1.9 million, respectively, of long-term liability for remediation and reclamation obligations. The recorded obligations do not include any anticipated insurance recoveries. The majority of payments related to these obligations are expected to be made over the next five years. Management regularly monitors the remediation and reclamation process and the liabilities recorded and believes its environmental obligations are adequate to fund remedial actions to comply with present laws and regulations, and that the ultimate liability for these matters, if any, will not differ materially from recorded amounts nor materially affect the overall results of operations, cash flows or financial condition of WGP. There can be no assurance, however, that current regulatory requirements will not change, or past non-compliance with environmental issues will not be discovered. See Note 11 and Note 12.

14. COMMITMENTS AND CONTINGENCIES (CONTINUED)

Litigation and legal proceedings. In March 2011, DCP Midstream, LP (“DCP”) filed a lawsuit against Anadarko and others, including a subsidiary of WES, Kerr-McGee Gathering, LLC, in Weld County District Court (the “Court”) in Colorado, alleging that Anadarko diverted gas from DCP’s gathering and processing facilities in breach of certain dedication agreements. In addition to various claims against Anadarko, DCP is claiming unjust enrichment and other damages against Kerr-McGee Gathering, LLC, the entity that holds the Wattenberg assets (located in the DJ Basin complex). Anadarko countersued DCP asserting that DCP has not properly allocated values and charges to Anadarko for the gas that DCP gathers and/or processes, and seeks a judgment that DCP has no valid gathering or processing rights to much of the gas production it is claiming, in addition to other claims.

In July 2011, the Court denied the defendants’ motion to dismiss without ruling on the merits. In August 2014, the judge scheduled a jury trial for July 2015. In preparation for trial, the parties amended their pleadings in October 2014 and are engaged in discovery and motion practice. Management does not believe the outcome of this proceeding will have a material effect on the financial condition, results of operations or cash flows of WGP. WES intends to vigorously defend this litigation. Furthermore, without regard to the merit of DCP’s claims, management believes that WES has adequate contractual indemnities covering the claims against it in this lawsuit.

In addition, from time to time, WGP, through its partnership interests in WES, is involved in legal, tax, regulatory and other proceedings in various forums regarding performance, contracts and other matters that arise in the ordinary course of business. Management is not aware of any such proceeding for which a final disposition could have a material adverse effect on the financial condition, results of operations or cash flows of WGP.

Other commitments. WES has short-term payment obligations, or commitments, related to its capital spending programs, as well as those of its unconsolidated affiliates. As of December 31, 2014, WES had unconditional payment obligations for services to be rendered or products to be delivered in connection with its capital projects of $64.1 million, the majority of which is expected to be paid in the next twelve months. These commitments relate primarily to projects at the DJ Basin complex, which include the continued construction of Train II at the Lancaster plant and compressor expansions.

Lease commitments. Anadarko, on WES’s behalf, has entered into lease agreements for corporate offices, shared field offices and a warehouse supporting WES’s operations, for which Anadarko charges WES rent. The leases for the corporate offices and shared field offices extend through 2017 and 2018, respectively, and the lease for the warehouse extends through February 2015.

Rent expense associated with the office, warehouse and equipment leases was $3.5 million, $2.8 million and $3.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.

The amounts in the table below represent existing contractual operating lease obligations as of December 31, 2014, that may be assigned or otherwise charged to WES pursuant to the reimbursement provisions of the WES omnibus agreement:
