Organization, Consolidation and Presentation of Financial Statements [Abstract]
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"). Effective August 13, 2020, the Partnership closed the transaction contemplated by a definitive exchange agreement with the general partner to eliminate all of the incentive distribution rights ("IDRs") held by the general partner and convert the 2% general partner interest into a non-economic general partner interest, such transaction the "IDR Restructuring Transaction." Effective May 1, 2020, the Partnership, through its wholly-owned subsidiary DKL Transportation, LLC, acquired Delek Trucking, LLC consisting of certain leased and owned tractors and trailers and related assets (the "Trucking Assets") from Delek Holdings, such transaction the "Trucking Assets Acquisition." In addition, effective March 31, 2020, the Partnership, through its wholly-owned subsidiary DKL Permian Gathering, LLC, acquired from Delek Holdings a crude oil gathering system located in Howard, Borden and Martin Counties, Texas (the "Big Spring Gathering System"), and certain related assets, such transaction the "Big Spring Gathering Assets Acquisition." Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. 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 U.S. 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, 2020 (our "Annual Report on Form 10-K"), filed with the U.S. Securities and Exchange Commission (the "SEC") on March 1, 2021 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, 2020 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. Reclassifications Certain immaterial reclassifications have been made to prior period presentation in order to conform to the current period presentation. Risks and Uncertainties Arising from the COVID-19 Pandemic U.S. economic activity continued on a recovery trend during the quarter ended June 30, 2021, albeit remaining subject to heightened levels of uncertainty related to the on-going impact of the COVID-19 outbreak that developed into a pandemic in March 2020 (the “COVID-19 Pandemic” or the “Pandemic”), and the spread of new variants of the virus. Some of the restrictions imposed in the prior year to prevent its spread have been eased and the government vaccination campaigns continue to yield positive results in terms of increase in the number of people who have been inoculated, a critical requirement to continue removing restrictions. Compared to the prior year, the economic recovery trends in the three and six months ended June 30, 2021 included a resumption of flights by major airlines and increased motor vehicle use. This has in turn resulted in increased demand and market prices for crude oil and other products, particularly refined petroleum products from which we receive revenue for transporting and storing. We also saw an increase in demand and sales volumes in our wholesale marketing business during the three and six months ended June 30, 2021. Nonetheless, there remains continued uncertainty about the duration and future impact of the COVID-19 Pandemic. Our business model, which includes executing minimum volume commitment contracts with our major customers, to an extent, cushioned us from the impact of the COVID-19 Pandemic in 2020 and during the three and six months ended June 30, 2021. Uncertainties related to the impact of the COVID-19 Pandemic and other events exist that could impact our future results of operations and financial position, the nature of which and the extent to which are currently unknown. To the extent these uncertainties have been identified and are believed to have an impact on our current period results of operations or financial position based on the requirements for assessing such financial statement impact under GAAP, we have considered them in the preparation of our financial statements as of and for the three and six months ended June 30, 2021. New Accounting Pronouncements Adopted During 2021 ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 In January 2020, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Codification ("ASU") 2020-01 which is intended to clarify interactions between the guidance to account for certain equity securities under Topics 321, 323 and 815, and improve current GAAP by reducing diversity in practice and increasing comparability of accounting. The pronouncement is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2020, and early adoption is permitted. We adopted this guidance prospectively on January 1, 2021. The adoption of this guidance did not have a material impact on our business, financial condition or results of operations. Accounting Pronouncements Not Yet Adopted ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848) In March 2020, the FASB issued an amendment which is intended to provide temporary optional expedients and exceptions to GAAP guidance on contracts, hedge accounting and other transactions affected by the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank rates. This guidance is effective for all entities any time beginning on March 12, 2020 through December 31, 2022 and may be applied from the beginning of an interim period that includes the issuance date of the ASU. The Partnership is evaluating the impact of this guidance but does not currently expect that adopting this new guidance will have a material impact on its condensed consolidated financial statements and related disclosures.
