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. See "Crude Oil Releases" below for further discussion.

Environmental, Health and Safety

We are subject to extensive federal, state and local environmental and safety laws and regulations enforced by various agencies, including the Environmental Protection Agency (the "EPA"), the United States Department of Transportation, the Occupational Safety and Health Administration, as well as numerous state, regional and local environmental, safety and pipeline agencies. These laws and regulations govern the discharge of materials into the environment, waste management practices, pollution prevention measures, as well as the safe operation of our pipelines and the safety of our workers and the public. Numerous permits or other authorizations are required under these laws and regulations for the operation of our terminals, pipelines, saltwells, trucks, and related operations, and may be subject to revocation, modification and renewal.

These laws and permits raise potential exposure to 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 handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and we expect that there 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. While it is often difficult to quantify future environmental or safety related expenditures, we anticipate that continuing capital investments and changes in operating procedures will be required to comply with existing and new requirements, as well as evolving interpretations and more strict enforcement of existing laws and regulations.

Releases of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, or is not a reimbursable event under the Omnibus Agreement, 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.

Crude Oil Releases

We have experienced several crude oil releases involving our assets, including, but not limited to, the following releases:


•	In February 2018, a release of approximately 203 barrels of crude oil, occurred from our SALA Gathering System near Urbana, Arkansas Station.


•	In March 2013, a release of approximately 5,900 barrels of crude oil, the majority of which was contained on-site, 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 and other releases have been substantially completed, although regulatory authorities could require additional remediation based on the results of our remediation efforts. 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. Expenses incurred for the remediation of these crude oil releases are included in operating expenses in our condensed consolidated statements of income and comprehensive income and are subsequently reimbursed by Delek pursuant to the terms of the Omnibus Agreement. Reimbursements are recorded as a reduction to operating expense. 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 available insurance reimbursement, will have a material adverse effect upon our business, financial condition or results of operations as we are reimbursed by Delek for such costs.

During each of the three and six months ended June 30, 2018, we recorded approximately $0.1 million of expense, which is net of total expected reimbursements from Delek pursuant to the terms of the Omnibus Agreement of $7.8 million, to cover the cost of certain asset failures that occurred in 2018.

The United States Department of Justice (the "DOJ"), on behalf of the EPA, and the State of Arkansas, on behalf of the Arkansas Department of Environmental Quality, are currently pursuing an enforcement action against the Partnership with regard to potential violations of the Clean Water Act and certain state laws arising from the Magnolia Release. Although we have been negotiating a resolution to this matter with the EPA and the State of Arkansas, which will include monetary penalties and other relief, on July 13, 2018, the DOJ and the State of Arkansas filed a civil action against two of the Partnership's wholly-owned subsidiaries, Delek Logistics Operations LLC and SALA Gathering Systems LLC, in the United States District Court for the Western District of Arkansas on July 13, 2018. As of June 30, 2018, we have accrued $1.0 million, which we recorded in pipeline release liabilities in our condensed consolidated balance sheet, for the Magnolia Release in connection with these proceedings. We believe this amount is adequate to cover our expected obligations related to these proceedings and that these proceedings will not have a material adverse effect upon the Partnership's business, financial condition or result of operations.

Contracts and Agreements

The majority of the petroleum products we sold in west Texas prior to December 31, 2017 were purchased from Noble Petro, Inc. ("Noble Petro"). Under the terms of a supply contract (the "Abilene Contract") with Noble Petro that expired on December 31, 2017, we purchased 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 leased the Abilene and San Angelo, Texas terminals to Noble Petro, under a separate Terminal and Pipeline Lease and Operating Agreement, that expired on December 31, 2017. In the first half of 2018, we purchased spot barrels from various third parties and from Delek for sale to wholesale customers in west Texas.

Letters of Credit

At June 30, 2018, we had no letters of credit in place under the DKL Revolver.
