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, all in exchange for 14.0 million newly issued common limited partner units and $45.0 million in cash ("IDR Restructuring Transaction"). Refer to Note 3 - Related Party Transactions for further information, Note 5 - Net Income per Unit for more information on how these transactions impact our earnings per unit calculations, and Note 8 - Equity for additional information on the impact to our equity accounts. 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." See Note 2 for further information. 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." See Note 2 for further information. 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 The on-going impact of the COVID-19 outbreak and its development into a pandemic in March 2020 (the “COVID-19 Pandemic” or the “Pandemic”), the restrictions imposed to prevent its spread, the challenges with the vaccination rollout, and the spread of new variants of the virus, continue to cause significant economic disruption globally, including in the U.S. and specific geographic areas where we operate. Compared to the prior year, the first quarter of 2021 has witnessed economic recovery trends including a resumption of flights by major airlines and increased motor vehicle use. This has in turn resulted in increased demand for, thus also the market prices of, crude oil and certain products, particularly refined petroleum products that we receive revenue for the transportation and storage services we provide and an increase in demand and sales volumes in our wholesale marketing business. As of March 31, 2021 there is 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 first quarter of 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 months ended March 31, 2021. New Accounting Pronouncements Adopted During 2021 ASU 2019-12, Simplifying the Accounting for Income Taxes In December 2019, the Financial Accounting Standards Board (the “FASB”) issued guidance intended to simplify various aspects related to accounting for income taxes, eliminate certain exceptions within Accounting Standards Codification ("ASC") 740 and clarify certain aspects of the current guidance to promote consistency among reporting entities. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 2020, with early adoption 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. 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 FASB issued 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.
