Organization and Basis of Presentation [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. References in this report to "Delek" refer collectively to Delek US Holdings, Inc. and any of its subsidiaries, other than Delek Logistics Partners, LP and its subsidiaries and its general partner (as hereinafter defined). The Partnership is a Delaware limited partnership formed in April 2012 by Delek and its subsidiary Delek Logistics GP, LLC, our general partner (our "general partner"). On March 31, 2015, the Partnership, through its wholly owned subsidiary Delek Logistics Operating, LLC ("OpCo"), acquired from Delek two crude oil rail offloading racks, which are designed to receive up to 25,000 barrels per day (“bpd”) of light crude oil or 12,000 bpd of heavy crude oil, or any combination of the two, delivered by rail to Delek's El Dorado, Arkansas refinery (the "El Dorado Refinery"), and related ancillary assets (the “El Dorado Assets”) (such transaction, the "El Dorado Rail Offloading Racks Acquisition"). On March 31, 2015, the Partnership, through its wholly owned subsidiary Delek Marketing & Supply, LP, acquired from Delek a crude oil storage tank (the "Tyler Crude Tank") located adjacent to Delek's Tyler, Texas refinery (the "Tyler Refinery") and certain ancillary assets (collectively, with the Tyler Crude Tank, the "Tyler Assets") (such transaction, the "Tyler Crude Tank Acquisition"). The Tyler Crude Tank has approximately 350,000 barrels of shell capacity and primarily supports the Tyler Refinery. The Tyler Assets, together with the El Dorado Assets, are hereinafter collectively referred to as the "Logistics Assets." The El Dorado Rail Offloading Racks Acquisition and the Tyler Crude Tank Acquisition are hereinafter collectively referred to as the "Acquisitions from Delek." The Acquisitions from Delek were accounted for as transfers between entities under common control. As entities under common control with Delek, we record the assets that Delek has contributed to us on our balance sheet at Delek's historical basis instead of fair value. Transfers between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior periods are retrospectively adjusted to furnish comparative information. Accordingly, the accompanying financial statements and related notes of the Partnership have been retrospectively adjusted to include (i) the historical results of the El Dorado Assets, as owned and operated by Delek through March 31, 2015 (the "El Dorado Assets Predecessor") and (ii) the historical results of the Tyler Assets, as owned and operated by Delek through March 31, 2015 (the "Tyler Assets Predecessor"). The El Dorado Assets Predecessor, together with the Tyler Assets Predecessor, are hereinafter collectively referred to as the "Logistics Assets Predecessor." See Note 2 for further information regarding the El Dorado Rail Offloading Racks Acquisition and the Tyler Crude Tank Acquisition. The accompanying unaudited condensed consolidated financial statements and related notes for the three and six month period ended June 30, 2016 include the consolidated financial position, results of operations, cash flows and equity of the Logistics Assets Predecessor as appropriate. The financial statements of the Logistics Assets Predecessor have been prepared from the separate records maintained by Delek and may not necessarily be indicative of the conditions that would have existed or the results of operations if the Logistics Assets Predecessor had been operated as unaffiliated entities. For example, the Logistics Assets Predecessor did not record revenues for intercompany terminalling, throughput, storage or other services. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. 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, 2015 (our "Annual Report on Form 10-K"), filed with the Securities and Exchange Commission (the "SEC") on February 29, 2016. 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, 2015 included in our Annual Report on Form 10-K. In the opinion of management, 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 significant intercompany transactions and account balances have been eliminated in the consolidation. Such intercompany transactions do not include those with Delek or our general partner. 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. Certain prior period amounts have been reclassified in order to conform to the current year presentation. These reclassifications had no effect on net income or partners' equity as previously reported. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. New Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance that requires organizations to use historical experience, current conditions, reasonable and supportable forecasts and forward-looking information in the measurement of all expected credit losses on financial instruments to more accurately estimate those losses. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted after December 15, 2018, and interim periods within those fiscal years. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition or results of operations. In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for excess tax benefits and deficiencies, classification of awards as either equity or liabilities and classification of excess tax benefits on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for any interim or annual financial statements that have not yet been issued. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition or results of operations. In February 2016, the FASB issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial position for all leases previously accounted for as operating leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial position or results of operations. In February 2015, the FASB issued guidance that amends and simplifies the requirements for consolidation and provides additional guidance to reporting entities in evaluating whether certain legal entities such as limited partnerships, limited liability corporations and securitization structures, should be consolidated. This guidance is effective for interim and annual periods beginning after December 15, 2015. We adopted this guidance on the effective date and the adoption did not have a material impact on our business, financial position or results of operations.

Acquisitions [Abstract]
Acquisitions	Acquisitions Acquisitions from Delek During the six month period ended June 30, 2015 , the Partnership acquired the assets listed below from Delek: • the El Dorado Assets, effective March 31, 2015 , for approximately $42.5 million in cash financed with borrowings under the Partnership's amended and restated senior secured revolving credit facility; and • the Tyler Assets, effective March 31, 2015 , for approximately $19.4 million in cash financed with borrowings under the Partnership's amended and restated senior secured revolving credit facility. Financial Results of the El Dorado Assets and the Tyler Assets The acquisitions of the El Dorado Assets and the Tyler Assets were considered transfers of businesses between entities under common control. Accordingly, the El Dorado Rail Offloading Racks Acquisition and the Tyler Crude Tank Acquisition were recorded at amounts based on Delek's historical carrying values as of the acquisition date, which were $7.6 million and $11.6 million as of March 31, 2015 , respectively. Our historical financial statements have been retrospectively adjusted to reflect the results of operations, financial position, cash flows and equity attributable to the El Dorado Assets and the Tyler Assets, as if we owned the assets for the period ended March 31, 2015 . The results of the El Dorado Assets and the Tyler Assets are included in the pipelines and transportation segment. The table below presents our results of operations, the effect of including the results of the El Dorado Assets and the Tyler Assets, and the adjusted total amounts included in our consolidated financial statements for the six months ended June 30, 2015 .

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Commercial Agreements The Partnership has a number of commercial agreements with Delek under which we provide various services, including crude oil gathering and crude oil, intermediate and refined products transportation and storage services, and marketing, terminalling and offloading services. Fees under each agreement are payable to us monthly by Delek or certain third parties to whom Delek has assigned certain of its rights and are generally subject to increase or decrease on July 1 of each year, by the amount of any change in various inflation-based indices, including the Federal Energy Regulatory Commission oil pipeline index or various iterations of the consumer price index and the producer price index; provided, however, that in no event will the fees be adjusted below the amount initially set forth in the applicable agreement. See our Annual Report on Form 10-K for a more complete description of certain of our commercial agreements and other agreements with Delek. Omnibus Agreement. The Partnership entered into an omnibus agreement with Delek, our general partner, OpCo, Lion Oil Company and certain of the Partnership's and Delek's other subsidiaries on November 7, 2012, which was subsequently amended and restated on July 26, 2013, February 10, 2014 and March 31, 2015 in connection with our subsequent acquisitions from Delek (collectively, the "Omnibus Agreement"). The third amendment and restatement occurring on March 31, 2015 generally provided for the following: (i) revisions of the schedules to include the El Dorado Assets and the Tyler Assets, (ii) revisions of certain provisions and schedules with respect to certain environmental matters, (iii) the addition of DKL Transportation, LLC as a party to the agreement, (iv) the elimination of certain provisions under the Omnibus Agreement that had expired, and (v) updating the annual administrative fee payable by us to Delek for general corporate and administrative services that Delek and its affiliates provide to us to reflect the inflationary increase provided for under the Omnibus Agreement, from $3.3 million to $3.4 million , which is prorated and payable monthly. The Partnership entered into an amendment to the third amended and restated omnibus agreement on August 3, 2015, with an effective date of April 1, 2015 (the third amended and restated omnibus agreement between the Partnership, Delek and the general partner, as amended, is referred to as the "Third Restated Omnibus Agreement"). This amendment eliminated a $1.0 million per event deductible that applied to certain asset failures before Delek was required to reimburse the Partnership. Pursuant to the terms of the Omnibus Agreement, we were reimbursed for certain capital expenditures in the amount of $0.6 million and $0.8 million during the three and six months ended June 30, 2016 , respectively, and $1.4 million and $2.6 million during the three and six months ended June 30, 2015 , respectively. These amounts are recorded in other long term liabilities and are amortized to revenue over the life of the underlying revenue agreement corresponding to the asset. Ad ditionally, we were reimbursed or indemnified, as the case may be, for costs incurred in excess of certain amounts related to certain asset failures pursuant to the terms of the Omnibus Agreeme nt. We were reimbursed $0.1 million and $1.0 million for these matters during the three and six months ended June 30, 2016 , respectively. During the three and six months ended June 30, 2015 , we were reimbursed for the costs incurred in connection with an asset failure near Fouke, Arkansas and the subsequent repair of the asset pursuant to the terms of the Third Restated Omnibus Agreement. Logistics Assets Predecessor Transactions Related-party transactions of the Logistics Assets Predecessor were settled through division equity. Costs related specifically to us have been identified and included in the accompanying consolidated statements of income and comprehensive income. Prior to the Acquisitions from Delek, we were not allocated certain corporate costs. These costs were primarily allocated based on a percentage of salaries expense and property, plant and equipment costs. In the opinion of management, the methods for allocating these costs are reasonable. It is not practicable to estimate the costs that would have been incurred by us if the Logistics Assets Predecessor had been operated on a stand-alone basis. Summary of Transactions Revenues from affiliates consist primarily of revenues from gathering, transportation, storage, offloading, wholesale marketing and products terminalling services provided primarily to Delek based on regulated tariff rates or contractually based fees, as well as product sales to Alon USA Energy, Inc., an equity method investee of Delek. The Logistics Assets Predecessor did not record revenues for intercompany terminalling, throughput, storage or other services. Affiliate operating expenses are primarily comprised of amounts we reimburse Delek, or our general partner, as the case may be, for the services provided to us under the First Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement"). These expenses could also include reimbursement and indemnification amounts from Delek, as provided under the Third Restated Omnibus Agreement. Additionally, the Partnership is required to reimburse Delek for direct or allocated costs and expenses incurred by Delek on behalf of the Partnership and for charges Delek incurred for the management and operation of our logistics assets, including an annual fee for various centralized corporate services, which are included in general and administrative services. In addition to these transactions, we purchase finished products and bulk biofuels from Delek, the costs of which are included in cost of goods sold. A summary of revenue and expense transactions with Delek and its affiliates, including expenses directly charged and allocated to our Logistics Assets Predecessor, are as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Revenues $ 36,694 $ 39,871 $ 75,454 $ 72,151 Cost of goods sold $ 8,127 $ 36,842 $ 18,817 $ 43,749 Operating and maintenance expenses (1) $ 7,085 $ 7,509 $ 14,750 $ 14,894 General and administrative expenses $ 1,608 $ 1,577 $ 2,954 $ 2,833 (1) Operating and maintenance expenses include costs allocated to the Logistics Assets Predecessor for operating support provided by Delek, including certain labor related costs, property and liability insurance costs and certain other operating expenses. The costs that were allocated to us by Delek were $0.2 million for the six months ended June 30, 2015 . Quarterly Cash Distributions Our common and general partner unitholders and the holders of incentive distribution rights ("IDRs") are entitled to receive quarterly distributions of available cash as it is determined by the board of directors of our general partner in accordance with the terms and provisions of our Partnership Agreement. In February and May 2016 , we paid quarterly cash distributions, of which $10.5 million and $11.3 million , respectively, were paid to Delek and our general partner. On July 25, 2016 , our general partner's board of directors declared a quarterly cash distribution totaling $18.1 million , based on the available cash as of the date of determination for the end of the second quarter of 2016 , payable on August 12, 2016 , of which $12.1 million is expected to be paid to Delek and our general partner, including the payment for the IDRs.

Second Amended and Restated Credit Agreement [Abstract]
Second Amended and Restated Credit Agreement	Second Amended and Restated Credit Agreement We entered into a senior secured revolving credit agreement on November 7, 2012 , with Fifth Third Bank, as administrative agent, and a syndicate of lenders. The agreement was amended and restated on July 9, 2013 (the "Amended and Restated Credit Agreement") and was most recently amended and restated on December 30, 2014 (the “Second Amended and Restated Credit Agreement”). Under the terms of the Second Amended and Restated Credit Agreement, the lender commitments were increased from $400.0 million to $700.0 million . The Second Amended and Restated Credit Agreement also contains an accordion feature whereby the Partnership can increase the size of the credit facility to an aggregate of $800.0 million , subject to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent. While the majority of the terms of the Second Amended and Restated Credit Agreement are substantially unchanged from the predecessor facility, among other things, changes were made to certain negative covenants, the financial covenants and the interest rate pricing grid. The Second Amended and Restated Credit Agreement contains an option for Canadian dollar denominated borrowings. Borrowings denominated in U.S. dollars bear interest at either a U.S. dollar prime rate , plus an applicable margin, or the London Interbank Offered Rate (" LIBOR "), plus an applicable margin, at the election of the borrowers. Borrowings denominated in Canadian dollars bear interest at either a Canadian dollar prime rate , plus an applicable margin, or the Canadian Dealer Offered Rate , plus an applicable margin, at the election of the borrowers. The applicable margin in each case varies based upon the Partnership's most recent leverage ratio calculation delivered to the lenders, as called for and defined under the terms of the credit facility. At June 30, 2016 , the weighted average interest rate for our borrowings under the facility was approximately 2.8% . Additionally, the Second Amended and Restated Credit Agreement requires us to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of June 30, 2016 , this fee was 0.4% per year. The obligations under the Second Amended and Restated Credit Agreement remain secured by first priority liens on substantially all of the Partnership's and its subsidiaries' tangible and intangible assets. Additionally, Delek Marketing & Supply, LLC ("Delek Marketing"), a direct wholly owned subsidiary of Delek, continues to provide a limited guaranty of the Partnership's obligations under the Second Amended and Restated Credit Agreement. Delek Marketing's guaranty is (i) limited to an amount equal to the principal amount, plus unpaid and accrued interest, of a promissory note made by Delek US in favor of Delek Marketing (the "Holdings Note") and (ii) secured by Delek Marketing's pledge of the Holdings Note to our lenders under the Second Amended and Restated Credit Agreement. As of June 30, 2016 , the principal amount of the Holdings Note was $102.0 million , plus unpaid interest accrued since the issuance date. The Second Amended and Restated Credit Agreement matures on December 30, 2019 . As of June 30, 2016 , we had $362.6 million in outstanding borrowings under the Second Amended and Restated Credit Agreement. Additionally, we had in place letters of credit totaling $7.5 million , primarily securing obligations with respect to gasoline and diesel purchases. No amounts were drawn under these letters of credit at June 30, 2016 . Unused credit commitments under the Second Amended and Restated Credit Agreement as of June 30, 2016 were $329.9 million .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For tax purposes, each partner of the Partnership is required to take into account its share of income, gain, loss and deduction in computing its federal and state income tax liabilities, regardless of whether cash distributions are made to such partner by the Partnership. The taxable income reportable to each partner takes into account differences between the tax basis and fair market value of our assets, the acquisition price of such partner's units and the taxable income allocation requirements under our Partnership Agreement.

Net Income Per Unit [Abstract]
Net Income Per Unit	Net Income Per Unit We use the two-class method when calculating the net income per unit applicable to limited partners because we have more than one participating class of securities. Our participating securities consist of common units, subordinated units, general partner units and IDRs. The two-class method is based on the weighted-average number of common units outstanding during the period. Basic net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting our general partner’s 2% interest and IDRs, by the weighted-average number of outstanding common and subordinated units. Our net income is allocated to our general partner and limited partners in accordance with their respective partnership percentages after giving effect to priority income allocations for IDRs to our general partner, which is the holder of the IDRs pursuant to our Partnership Agreement, which are paid following the close of each quarter. Earnings in excess of distributions are allocated to our general partner and limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. Diluted net income per unit applicable to common limited partners includes the effects of potentially dilutive units on our common units. At present, the only potentially dilutive units outstanding consist of unvested phantom units. Basic and diluted net income per unit applicable to subordinated limited partners are the same because there are no potentially dilutive subordinated units outstanding. Following the February 12, 2016 payment of the cash distribution attributable to the fourth quarter of 2015 and confirmation by the board of directors of our general partner (based on the recommendation of the Conflicts Committee) on February 25, 2016 that the requirements under the Partnership Agreement for the conversion of all subordinated units into common units were satisfied, the subordination period for such subordinated units ended. As a result, in the first quarter of 2016, each of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. The conversion did not impact the amount of the cash distribution paid or the total number of the Partnership's outstanding units representing limited partner interests. The Partnership's net income was allocated to the general partner and the limited partners, including the holders of the subordinated units through February 24, 2016, in accordance with our Partnership Agreement. Our distributions earned with respect to a given period are declared subsequent to quarter end. Therefore, the table below represents total cash distributions applicable to the period in which the distributions are earned. The expected date of distribution for the distributions earned during the period ended June 30, 2016 is August 12, 2016 . The calculation of net income per unit is as follows (dollars in thousands, except units and per unit amounts): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Net income attributable to partners $ 18,893 $ 18,311 $ 34,341 $ 32,951 Less: General partner's distribution (including IDRs) (1) 2,775 1,030 5,061 1,898 Less: Limited partners' distribution 15,310 6,738 25,695 13,213 Less: Subordinated partner's distribution — 6,600 4,424 12,959 (Distributions) earnings excess $ 808 $ 3,943 $ (839 ) $ 4,881 General partner's earnings: Distributions (including IDRs) (1) $ 2,775 $ 1,030 $ 5,061 $ 1,898 Allocation of (distributions) earnings excess 16 79 (17 ) 98 Total general partner's earnings $ 2,791 $ 1,109 $ 5,044 $ 1,996 Limited partners' earnings on common units: Distributions $ 15,310 $ 6,738 $ 25,695 $ 13,213 Allocation of (distributions) earnings excess 792 1,952 (340 ) 2,416 Total limited partners' earnings on common units $ 16,102 $ 8,690 $ 25,355 $ 15,629 Limited partners' earnings on subordinated units: Distributions $ — $ 6,600 $ 4,424 $ 12,959 Allocation of (distributions) earnings excess — 1,912 (482 ) 2,367 Total limited partner's earnings on subordinated units $ — $ 8,512 $ 3,942 $ 15,326 Weighted average limited partner units outstanding (3) : Common units - (basic) 24,281,930 12,224,007 20,653,210 12,220,248 Common units - (diluted) 24,367,091 12,360,519 20,735,389 12,350,621 Subordinated units - Delek (basic and diluted) (2) — 11,999,258 3,626,149 11,999,258 Net income per limited partner unit (3) : Common units - (basic) $ 0.66 $ 0.71 $ 1.23 $ 1.28 Common units - (diluted) $ 0.66 $ 0.70 $ 1.22 $ 1.27 Subordinated units - Delek (basic and diluted) $ — $ 0.71 $ 1.09 $ 1.28 (1) General partner distributions (including IDRs) consist of the payment with respect to the 2% general partner interest and payment on the IDRs, which represent the right of the general partner to receive increasing percentages of quarterly distributions of available cash from operating surplus in excess of $0.43125 per unit per quarter. See Note 8 for further discussion related to IDRs. (2) On February 25, 2016, each of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. Distributions and the Partnership's net income were allocated to the subordinated units through February 24, 2016. (3) We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflect the conversion of the subordinated units to common units on February 25, 2016.

Equity [Abstract]
Equity	Equity We had 9,504,264 common limited partner units held by the public outstanding as of June 30, 2016 . Additionally, as of June 30, 2016 , Delek owned a 59.7% limited partner interest in us, consisting of 14,798,516 common limited partner units and a 95.1% interest in our general partner, which owns the entire 2.0% general partner interest consisting of 495,975 general partner units. Affiliates who are also members of our general partner's management and board of directors own the remaining 4.9% interest in our general partner. Equity Activity On February 25, 2016, the requirements under the Partnership Agreement for the conversion of all subordinated units into common units were satisfied and the subordination period ended. As a result, in the first quarter of 2016, each of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. The conversion did not impact the amount of the cash distribution paid or the total number of the Partnership's outstanding units representing limited partner interests. The table below summarizes the changes in the number of units outstanding from December 31, 2015 through June 30, 2016 .

For purposes of maintaining partner capital accounts, the Partnership Agreement specifies that items of income and loss shall be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect to priority income allocations in an amount equal to incentive cash distributions allocated 100% to our general partner. The following table presents the allocation of the general partner's interest in net income (in thousands, except percentage of ownership interest): Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Net income attributable to partners $ 18,893 $ 18,311 $ 34,341 $ 32,951 Less: General partner's IDRs (2,462 ) (758 ) (4,446 ) (1,364 ) Net income available to partners $ 16,431 $ 17,553 $ 29,895 $ 31,587 General partner's ownership interest 2.0 % 2.0 % 2.0 % 2.0 % General partner's allocated interest in net income $ 329 $ 351 $ 598 $ 632 General partner's IDRs 2,462 758 4,446 1,364 Total general partner's interest in net income $ 2,791 $ 1,109 $ 5,044 $ 1,996 Incentive Distribution Rights The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and our unitholders in any available cash from operating surplus that we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner include its 2.0% general partner interest and assume that (i) our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (ii) our general partner has not transferred its IDRs, and (iii) there are no arrearages on common units.

Equity Based Compensation [Abstract]
Equity Based Compensation	Equity Based Compensation We incurred approximately $0.1 million and $0.2 million of unit-based compensation expense related to the Partnership during the three and six months ended June 30, 2016 , respectively, and $0.1 million and $0.2 million during the three and six months ended June 30, 2015 , respectively. These amounts are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. The fair value of phantom unit awards under the LTIP is determined based on the closing price of our common limited partner units on the grant date. The estimated fair value of our phantom units is amortized over the vesting period using the straight line method. Awards vest over one to five -year service periods unless such awards are amended in accordance with the LTIP. As of June 30, 2016 , there was $1.0 million of total unrecognized compensation cost related to non-vested equity-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.8 years.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments Disclosure [Text Block]	In March 2015, the Partnership, through its indirect wholly owned subsidiary DKL Caddo, LLC ("DKL Caddo"), became a member of Caddo Pipeline, LLC ("CP LLC") by entering into an amended and restated limited liability company agreement (the “Caddo LLC Agreement”) with Plains Pipeline, L.P. ("Plains"), an affiliate of Plains All American Pipeline, L.P. CP LLC was formed to plan, develop, construct, own, operate and maintain a pipeline system and certain ancillary assets originating near Longview, Texas and extending to Shreveport, Louisiana (the "Caddo Pipeline System"). Pursuant to the terms of the Caddo LLC Agreement, DKL Caddo and Plains each own a 50% membership interest in CP LLC. Pursuant to separate agreements, Plains will have primary responsibility for the construction of the Caddo Pipeline System, and, upon its completion, Plains will also have primary responsibility for its day-to-day operations. In March 2015, the Partnership, through its indirect wholly owned subsidiary, DKL RIO, LLC ("DKL RIO"), became a member of Rangeland RIO Pipeline, LLC ("Rangeland RIO") by entering into an amended and restated limited liability company agreement (the "Rangeland LLC Agreement") with Rangeland Energy II, LLC ("Rangeland"). Rangeland RIO was formed to plan, develop, construct, own, operate and maintain a pipeline system and certain ancillary assets extending from Loving County, Texas to Midland, Texas (the "RIO Pipeline"). Pursuant to the terms of the Rangeland LLC Agreement, DKL RIO owns 33% of Rangeland RIO, and Rangeland owns 67% . Rangeland will have primary responsibility for the construction of the RIO Pipeline, and, upon its completion, Rangeland will also have primary responsibility for its day-to-day operations. The investment in these two entities is expected to be financed through a combination of cash from operations and borrowings under the Second Amended and Restated Credit Agreement. As of June 30, 2016 , the investments in these joint ventures totaled $73.4 million and were accounted for using the equity method. We do not consolidate any part of the assets or liabilities of our equity investees. Our share of net income or loss will increase or decrease, as applicable, the carrying value of our investments in unconsolidated affiliates. With respect to CP LLC and Rangeland RIO, we determined that these entities do not represent variable interest entities and consolidation was not required. We have the ability to exercise influence over each of these joint ventures through our participation in the management committees, which make all significant decisions. However, since all significant decisions require the consent of the other investor(s) without regard to economic interest, we have determined that we have joint control and have applied the equity method of accounting. Our investment in these joint ventures is reflected in our pipelines and transportation segment.

Segment Reporting [Abstract]
Segment Data	Segment Data We aggregate our operating units into two reportable segments: (i) pipelines and transportation and (ii) wholesale marketing and terminalling: • The assets and investments reported in the pipelines and transportation segment provide crude oil gathering and crude oil, intermediate and finished products transportation and storage services to Delek's refining operations and independent third parties. • The wholesale marketing and terminalling segment provides wholesale marketing and terminalling services to Delek's refining operations and independent third parties. Our operating segments adhere to the accounting policies used for our consolidated financial statements. Our operating segments are managed separately because each segment requires different industry knowledge, technology and marketing strategies. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of its reportable segments based on segment contribution margin. Segment contribution margin is defined as net sales less cost of sales and operating expenses, excluding depreciation and amortization. On March 31, 2015 , we acquired the Logistics Assets from Delek. Our historical financial statements have been retrospectively adjusted as appropriate to reflect the results of operations attributable to the Logistics Assets as if we owned the assets for all periods presented. The results of the Logistics Assets are included in the pipelines and transportation segment.

Fair Value Measurements [Abstract]
Fair Value Measurements	Fair Value Measurements The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of our assets and liabilities that fall under the scope of ASC 825, Financial Instruments . We apply the provisions of ASC 820, which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 applies to our interest rate and commodity derivatives that are measured at fair value on a recurring basis. The standard also requires that we assess the impact of nonperformance risk on our derivatives. Nonperformance risk is not considered material at this time. ASC 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants. Over the counter ("OTC") commodity swaps and interest rate swaps and caps are generally valued using industry-standard models that consider various assumptions, including quoted forward prices, spot prices, interest rates, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines the classification as Level 2 or 3. Our contracts are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2. The fair value hierarchy for our financial assets accounted for at fair value on a recurring basis at June 30, 2016 and December 31, 2015 was as follows (in thousands): As of June 30, 2016 Level 1 Level 2 Level 3 Total Assets Interest rate derivatives $ — $ — $ — $ — OTC commodity swaps — 50 — 50 Total assets — 50 — 50 Liabilities OTC commodity swaps — (71 ) — (71 ) Net liabilities $ — $ (21 ) $ — $ (21 ) As of December 31, 2015 Level 1 Level 2 Level 3 Total Assets Interest rate derivatives $ — $ — $ — $ — OTC commodity swaps — 171 — 171 Total assets — 171 — 171 Liabilities OTC commodity swaps — (45 ) — (45 ) Net assets $ — $ 126 $ — $ 126 The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. Derivative assets and liabilities with the same counterparty are not netted where the legal right of offset exists. This differs from the presentation in the financial statements which reflects our policy under the guidance of ASC 815-10-45, wherein we have elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty where the legal right of offset exists. As of June 30, 2016 , $0.1 million of cash collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty. As of December 31, 2015 , $0.8 million of cash collateral was held by counterparty brokerage firms.

Derivative Instruments [Abstract]
Derivative Instruments	Derivative Instruments From time to time, we enter into forward fuel contracts to limit the exposure to price fluctuations for physical purchases of finished products in the normal course of business. We use derivatives to reduce normal operating and market risks with a primary objective in derivative instrument use being the reduction of the impact of market price volatility on our results of operations. Typically, we enter into forward fuel contracts with major financial institutions in which we fix the purchase price of finished grade fuel for a predetermined number of units with fulfillment terms of less than 90 days. From time to time, we may also enter into interest rate hedging agreements to limit floating interest rate exposure under the Second Amended and Restated Credit Agreement. Our initial credit facility required us to maintain interest rate hedging arrangements on at least 50% of the amount funded on November 7, 2012 under the credit facility, which was required to be in place for at least a three-year period beginning no later than March 7, 2013. Accordingly, effective February 25, 2013 , we entered into interest rate hedges in the form of a LIBOR interest rate cap for a term of three years for a total notional amount of $45.0 million , thereby meeting the requirements in effect at that time. These requirements were eliminated in connection with the Amended and Restated Credit Agreement in July 2013, but the interest rate hedge remained in place in accordance with its terms through its maturity date in February 2016. The following table presents the fair value of our derivative instruments, as of June 30, 2016 and December 31, 2015 . The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under our master netting arrangements, including any cash collateral on deposit with our counterparties. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements. As a result, the asset and liability amounts below may differ from the amounts presented in our consolidated balance sheets. During the three and six months ended June 30, 2016 and June 30, 2015 , we did not elect hedge accounting treatment for these derivative positions. As a result, all changes in fair value are marked to market in the accompanying condensed consolidated statements of income and comprehensive income.

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 business, financial condition or results of operations. See "Crude Oil Releases" below for additional information on a potential enforcement action. 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 or discharge of pollutants into or onto the land, air and water, the handling and disposal of solid and hazardous wastes and 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 are 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. The legislative and regulatory trend has been to place increasingly stringent restrictions and limitations on activities that may affect the environment. 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, monetary fines and 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 or a reimbursable event under the Third Restated 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. 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 experienced several crude oil releases involving our assets, including, but not limited to, the following releases: • In January 2016, a crude oil release of less than 30 barrels occurred from a gathering line at the Modisette pumping station near El Dorado, Arkansas (the "Modisette Release"); • In January 2016, a crude oil release of approximately 350 barrels occurred from the Paline Pipeline near Woodville, Texas (the "Paline Release"); • In April 2015, a crude oil release of an estimated 130 barrels of crude oil was discovered from a gathering line near Fouke, Arkansas (the "Fouke Release"); and • 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 with the exception of the Paline Release, for which remediation is expected to continue through the third quarter of 2016. 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 of June 30, 2016 , we have accrued $0.2 million for the Paline Release. Expenses incurred for the remediation of crude oil releases are included in operating expenses in our consolidated statements of income and comprehensive income and are subsequently reimbursed by Delek pursuant to the terms of the Third Restated 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 partial 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. In June 2015, the United States Department of Justice notified the Partnership that it was evaluating an enforcement action on behalf of the Environmental Protection Agency (the "EPA") with regard to potential Clean Water Act violations arising from the Magnolia Release. We are currently attempting to negotiate a resolution to this matter with the EPA and the state of Arkansas, which may include monetary penalties and/or other relief. As of June 30, 2016 we have accrued $1.0 million for the Magnolia Release in connection with these proceedings. 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 June 30, 2016 , we had in place letters of credit totaling $7.5 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 June 30, 2016 . 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 totaled $0.2 million and $0.5 million for the three and six months ended June 30, 2016 , respectively, and $0.4 million and $0.6 million for the three and six months ended June 30, 2015 , respectively.

Organization and Basis of Presentation [Abstract]
Combination of Entities under Common Control, Policy [Policy Text Block]	The El Dorado Rail Offloading Racks Acquisition and the Tyler Crude Tank Acquisition are hereinafter collectively referred to as the "Acquisitions from Delek." The Acquisitions from Delek were accounted for as transfers between entities under common control. As entities under common control with Delek, we record the assets that Delek has contributed to us on our balance sheet at Delek's historical basis instead of fair value. Transfers between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior periods are retrospectively adjusted to furnish comparative information. Accordingly, the accompanying financial statements and related notes of the Partnership have been retrospectively adjusted to include (i) the historical results of the El Dorado Assets, as owned and operated by Delek through March 31, 2015 (the "El Dorado Assets Predecessor") and (ii) the historical results of the Tyler Assets, as owned and operated by Delek through March 31, 2015 (the "Tyler Assets Predecessor"). The El Dorado Assets Predecessor, together with the Tyler Assets Predecessor, are hereinafter collectively referred to as the "Logistics Assets Predecessor." See Note 2 for further information regarding the El Dorado Rail Offloading Racks Acquisition and the Tyler Crude Tank Acquisition.
Consolidation, Policy [Policy Text Block]	All significant intercompany transactions and account balances have been eliminated in the consolidation. Such intercompany transactions do not include those with Delek or our general partner. All adjustments are of a normal, recurring nature. The accompanying unaudited condensed consolidated financial statements and related notes for the three and six month period ended June 30, 2016 include the consolidated financial position, results of operations, cash flows and equity of the Logistics Assets Predecessor as appropriate. The financial statements of the Logistics Assets Predecessor have been prepared from the separate records maintained by Delek and may not necessarily be indicative of the conditions that would have existed or the results of operations if the Logistics Assets Predecessor had been operated as unaffiliated entities. For example, the Logistics Assets Predecessor did not record revenues for intercompany terminalling, throughput, storage or other services.
Basis of Accounting, Policy [Policy Text Block]	Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. 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, 2015 (our "Annual Report on Form 10-K"), filed with the Securities and Exchange Commission (the "SEC") on February 29, 2016. 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, 2015 included in our Annual Report on Form 10-K.
Reclassification, Policy [Policy Text Block]	Certain prior period amounts have been reclassified in order to conform to the current year presentation. These reclassifications had no effect on net income or partners' equity as previously reported.
Use of Estimates, Policy [Policy Text Block]	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block]	In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance that requires organizations to use historical experience, current conditions, reasonable and supportable forecasts and forward-looking information in the measurement of all expected credit losses on financial instruments to more accurately estimate those losses. This guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted after December 15, 2018, and interim periods within those fiscal years. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition or results of operations. In March 2016, the FASB issued guidance that simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for excess tax benefits and deficiencies, classification of awards as either equity or liabilities and classification of excess tax benefits on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for any interim or annual financial statements that have not yet been issued. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition or results of operations. In February 2016, the FASB issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial position for all leases previously accounted for as operating leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial position or results of operations. In February 2015, the FASB issued guidance that amends and simplifies the requirements for consolidation and provides additional guidance to reporting entities in evaluating whether certain legal entities such as limited partnerships, limited liability corporations and securitization structures, should be consolidated. This guidance is effective for interim and annual periods beginning after December 15, 2015. We adopted this guidance on the effective date and the adoption did not have a material impact on our business, financial position or results of operations.

Net Income Per Unit [Abstract]
Earnings Per Share, Policy [Policy Text Block]	We use the two-class method when calculating the net income per unit applicable to limited partners because we have more than one participating class of securities. Our participating securities consist of common units, subordinated units, general partner units and IDRs. The two-class method is based on the weighted-average number of common units outstanding during the period. Basic net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting our general partner’s 2% interest and IDRs, by the weighted-average number of outstanding common and subordinated units. Our net income is allocated to our general partner and limited partners in accordance with their respective partnership percentages after giving effect to priority income allocations for IDRs to our general partner, which is the holder of the IDRs pursuant to our Partnership Agreement, which are paid following the close of each quarter.

Segment Reporting [Abstract]
Segment Reporting, Policy [Policy Text Block]	Our operating segments adhere to the accounting policies used for our consolidated financial statements. Our operating segments are managed separately because each segment requires different industry knowledge, technology and marketing strategies. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of its reportable segments based on segment contribution margin. Segment contribution margin is defined as net sales less cost of sales and operating expenses, excluding depreciation and amortization

(2) On February 25, 2016, each of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. Distributions and the Partnership's net income were allocated to the subordinated units through February 24, 2016. (3) We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflect the conversion of the subordinated units to common units on February 25, 2016.

[1]	We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflect the conversion of the subordinated units to common units on February 25, 2016. See Notes 7 and 8 for further discussion
[2]	General partner distributions (including IDRs) consist of the payment with respect to the 2% general partner interest and payment on the IDRs, which represent the right of the general partner to receive increasing percentages of quarterly distributions of available cash from operating surplus in excess of $0.43125 per unit per quarter. See Note 8 for further discussion related to IDRs.
[3]	We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflect the conversion of the subordinated units to common units on February 25, 2016.
[4]	On February 25, 2016, each of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. Distributions and the Partnership's net income were allocated to the subordinated units through February 24, 2016.
