Commitments and Contingencies [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Litigation In the ordinary conduct of our business, we are from time to time subject to lawsuits, investigations and claims, including environmental claims and employee-related matters. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, including civil penalties or other enforcement actions, we do not believe that any currently pending legal proceeding or proceedings to which we are a party will have a material adverse effect on our business, financial condition or results of operations. Environmental Health and Safety We are subject to extensive and periodically changing federal, state and local laws and regulations relating to the protection of the environment, health and safety. Among other things, these laws and regulations govern the emission of discharge of pollutants into or onto the land, air and water, the handling and disposal of solid and hazardous wastes, the remediation of contamination and the protection of workers and the public. Compliance with existing and anticipated environmental laws and regulations increases our overall cost of business, including our capital costs to develop, maintain, operate and upgrade equipment and facilities. Numerous permits or other authorizations are required under these laws for the operation of our terminals, pipelines, and related operations, and may be subject to revocation, modification and renewal. These laws and permits may become the basis for future claims and lawsuits involving environmental and safety matters, which could include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed of, or that relate to pre-existing conditions for which we have assumed or have assigned responsibility. We believe that our current operations are in substantial compliance with existing environmental, health and safety requirements. However, these laws and regulations are subject to changes by regulatory authorities, or to changes in the interpretation of such laws and regulations, by regulatory or judicial authorities, and continued and future compliance with such laws and regulations may require us to incur significant expenditures. Violation of environmental laws, regulations and permits can result in the imposition of significant administrative, civil and criminal penalties, injunctions limiting our operations, investigatory or remedial liabilities or construction bans or delays in the construction of additional facilities or equipment. Additionally, a release of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expenses, including costs to respond to, contain and remediate a release, to comply with applicable laws and regulations and to resolve claims by third parties for personal injury, property damage, or natural resources damages. These impacts could directly and indirectly affect our business. We cannot currently determine the amounts of such future impacts. There have been and will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including notices of violations, citations and other enforcement actions, some of which have resulted or may result in changes to operating procedures and in capital expenditures. Crude Oil Releases We have detected several crude oil releases involving our assets, including, but not limited to, the following releases:
• | In April 2015, a crude oil release of an estimated 130 barrels of crude oil was discovered from a gathering line in a remote area near Fouke, Arkansas (the "Fouke Release");
• | In April 2014, a release of about 400 barrels of crude oil occurred from a gathering line near Haynesville, Louisiana (the "Haynesville Release");
• | In October 2013, a release of less than 50 barrels of crude oil was discovered in a creek in a remote area near Macedonia in Columbia County, Arkansas (the "Macedonia Release");
• | In March 2013, a a release of approximately 5,900 barrels of crude oil occurred from a pumping facility at our Magnolia Station located west of the El Dorado refinery (the "Magnolia Release").
Cleanup operations and site maintenance and remediation efforts on these releases have been substantially completed. However, we may incur additional expenses as a result of further scrutiny by regulatory authorities and continued compliance with laws and regulations to which our assets are subject. As we are unable to estimate these additional expenses, we have accrued $0.1 million, $0.2 million and $1.0 million for the Fouke Release, the Haynesville Release and the Magnolia Release, respectively, as of December 31, 2015 for such expenses. A nominal amount was accrued as of December 31, 2015 for the Macedonia Release. In June 2015, the United States Department of Justice (the "DOJ") notified the Partnership that it was evaluating an enforcement action on behalf of the EPA with regard to potential Clean Water Act violations arising from the March 2013 release at Magnolia Station. The DOJ visited the Magnolia Station in July 2015 and we continue to work with them and respond to their information requests. However, no specific claim for penalties or affirmative relief has been made at this time. During the year ended December 31, 2015, we were reimbursed for the costs incurred in connection with the Fouke Release pursuant to the terms of the Third Restated Omnibus Agreement (as defined in Note 4). During the year ended December 31, 2014, we incurred costs of $1.0 million related to the Haynesville Release and during the year ended December 31, 2013, we incurred costs of $0.3 million for each of the Magnolia Release and the Macedonia Release. These costs are included in operating expenses in our consolidated statements of income and comprehensive income. We do not believe the total costs associated with these events, whether alone or in the aggregate, including any fines or penalties and net of partial insurance reimbursement, will have a material adverse effect upon our business, financial condition or results of operations, as Delek is required, pursuant to the terms of the Third Restated Omnibus Agreement (as defined in Note 4), to indemnify certain costs in excess of $0.3 million with respect to the releases at our Magnolia Station and near Macedonia, Arkansas and reimburse us for costs in excess of $1.0 million with respect to the release near Haynesville, Louisiana. Contracts and Agreements The majority of the petroleum products we sell in west Texas are purchased from Noble Petro, Inc. ("Noble Petro"). Under the terms of a supply contract (the "Abilene Contract") with Noble Petro, we have the right to purchase up to 20,350 bpd of petroleum products at the Abilene, Texas terminal, which we own, for sales and exchange with third parties at the Abilene and San Angelo terminals. We lease the Abilene and San Angelo, Texas terminals to Noble Petro, under a separate Terminal and Pipeline Lease and Operating Agreement, with a term that runs concurrent with that of the Abilene Contract. The Abilene Contract expires on December 31, 2017 and does not include any options for renewal. We also purchase spot barrels from various third parties and from Delek for sale to wholesale customers in west Texas. Letters of Credit As of December 31, 2015, we had in place letters of credit totaling $1.5 million under the Second Amended and Restated Credit Agreement, primarily securing obligations with respect to gasoline and diesel purchases. No amounts were drawn under these letters of credit at December 31, 2015. Operating Leases We lease certain equipment and have surface leases under various operating lease arrangements, most of which provide the option, after the initial lease term, to renew the leases. None of these lease arrangements include fixed rental rate increases. Lease expense for all operating leases for the years ended December 31, 2015, 2014 and 2013 totaled $1.1 million, $0.7 million and $0.7 million, respectively. The following is an estimate of our future minimum lease payments for operating leases having remaining noncancelable terms in excess of one year as of December 31, 2015 (in thousands):
2016 |  | $ | 4,991 |
2017 |  | 4,893 |
2018 |  | 2,184 |
2019 |  | 253 |
2020 |  | 189 |
Thereafter |  | 9 |
Total future minimum rentals |  | $ | 12,519 |
