Organization and Basis of Presentation	Organization and Basis of Presentation As used in this report, the terms "Delek Logistics Partners, LP," the "Partnership," "we," "us," or "our" may refer to Delek Logistics Partners, LP, one or more of its consolidated subsidiaries or all of them taken as a whole. The Partnership is a Delaware limited partnership formed in April 2012 by Delek US Holdings, Inc. ("Delek Holdings") and its subsidiary Delek Logistics GP, LLC, our general partner (our "general partner"). The Partnership provides gathering, pipeline and other transportation services primarily for crude oil and natural gas customers, storage, wholesale marketing and terminalling services primarily for intermediate and refined product customers, and water disposal and recycling services through its owned assets and joint ventures located primarily in the Permian Basin and other select areas in the Gulf Coast region. A majority of our existing assets are both integral to and dependent upon the success of Delek Holdings' refining operations, as many of our assets are contracted exclusively to Delek Holdings in support of its Tyler, Texas (the "Tyler Refinery"), El Dorado, Arkansas (the "El Dorado Refinery") and Big Spring, Texas (the "Big Spring Refinery"). On January 2, 2025, we acquired 100% of the limited liability company interests in Gravity Water Intermediate Holdings LLC from Gravity Water Holdings LLC (the "Seller") related to the Seller's water disposal and recycling operations in the Permian Basin and the Bakken (the “Gravity Acquisition”). See Note 2 for further information. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024 (our "Annual Report on Form 10-K"), filed with the U.S. Securities and Exchange Commission (the "SEC") on February 26, 2025 and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2024 included in our Annual Report on Form 10-K. All adjustments necessary for a fair presentation of the financial position and the results of operations for the interim periods presented have been included. All intercompany accounts and transactions have been eliminated. Such intercompany transactions do not include those with Delek Holdings or our general partner, which are presented as related parties in these accompanying condensed consolidated financial statements. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year. Accounting Pronouncements Not Yet Adopted ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) ("ASU 2024-03"). ASU 2024-03 requires disaggregation of expenses into specific categories such as purchase of inventory, employee compensation, depreciation, and intangible asset amortization, by relevant expense caption on the statement of operations. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted on either a prospective or retrospective basis. The adoption will not affect our financial position or our results of operations. The adoption of ASU 2024-03 will not affect our financial position or our results of operations, but will result in additional disclosures.

Commitments and Contingencies Disclosure [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 financial statements. Texas Department of Transportation Settlement Beginning in August 2023, the Partnership was involved in litigation with the State of Texas Department of Transportation. The subject of the litigation was the expansion of the highway where the Partnership's Nettleton Station is situated. As a result of this expansion, two tanks owned by the Partnership were impacted. This litigation was settled in the second quarter of 2024 and resulted in the Partnership recovering $8.3 million in condemnation proceeds, which was recorded in other operating income, net in the condensed consolidated statements of income and comprehensive income. In the first quarter of 2025, we recovered additional $4.3 million related to this settlement, which is recorded in other operating income, net in the accompanying condensed consolidated statements of income and comprehensive income. 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 and pollution prevention measures, as well as the safe operation of our pipelines and the safety of our workers and the public. The State of New Mexico promulgated new regulations to limit emissions from oil and gas operations in 2022. The cost to comply is not expected to be material. 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, surface water and groundwater contamination, air pollution, personal injury and property damage allegedly caused by substances which we may have handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we may 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 the receipt and response to 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 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 governmental agencies or other persons for personal injury, property damage, response costs, or natural resources damages.
