Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Organization Western Refining Logistics, LP ("WNRL" or the "Partnership"), "we," "us," and "our" refer to Western Refining Logistics, LP, and, unless the context otherwise requires, our subsidiaries. WNRL is a Delaware limited partnership formed in July 2013 by Western Refining Logistics GP, LLC ("WRGP" or the "General Partner"), our general partner. References to “Western” refer to Western Refining, Inc. WNRL is principally a growth-oriented partnership that was formed to own, operate, develop and acquire logistics and related assets and businesses including terminals, storage tanks, pipelines and other logistics assets related to the terminalling, transportation, storage and distribution of crude oil and refined products. WNRL's businesses include 705 miles of pipelines, approximately 12.4 million barrels of active shell storage capacity, distribution of wholesale petroleum products and crude oil and asphalt trucking. On June 1, 2017, Tesoro Corporation (renamed Andeavor on August 1, 2017) completed its acquisition of Western. Tahoe Merger Sub 1, Inc., a Delaware corporation and wholly-owned subsidiary of Andeavor, merged into Western, with Western surviving as a wholly-owned subsidiary of Andeavor (the "Andeavor Acquisition"). WNRL's agreements with Western have not changed as a result of the Andeavor Acquisition as such discussion about our affiliate agreements continue to refer to Western. See Note 17, Related Party Transactions , for additional information regarding these agreements. As of June 30, 2017 , Andeavor owned 52.5% of the limited partner interest in WNRL and public unitholders held the remaining 47.5% . WRGP is indirectly wholly-owned by Andeavor and holds all of the non-economic general partner interests in WNRL. See Note 11, Equity , for additional information. On April 17, 2017, Andeavor filed an Amendment to Schedule 13D with the Securities and Exchange Commission (the "SEC") stating that the board of directors of Andeavor authorized the management of Andeavor to work with the board of directors and management of Andeavor Logistics LP, formerly known as Tesoro Logistics LP ("Andeavor Logistics"), to consider, discuss and endeavor to negotiate a merger, consolidation or combination (in whatever form) of assets held by and securities issued by Andeavor Logistics and its affiliates and assets held by and securities issued by WNRL. On July 20, 2017, the chairman of the conflicts committee of the WRGP board of directors (the "WNRL Board") received a proposal from Andeavor Logistics to acquire WNRL in an all-stock transaction at an exchange ratio of 0.4906 common units of Andeavor Logistics ("Andeavor Logistics Common Units") for each WNRL common unit. There can be no assurance that any discussions that may occur between Andeavor Logistics and WNRL will contain transaction terms consistent with those described above or result in the entry into a definitive agreement concerning a transaction or, if such a definitive agreement is reached, will result in the consummation of a transaction provided for in such definitive agreement. Discussions concerning a possible transaction may be terminated at any time and without prior notice. Entry into a definitive agreement concerning a potential transaction and the consummation of any such transaction is subject to a number of contingencies, which are beyond the control of WNRL and Andeavor Logistics, including the satisfactory completion of due diligence, the approval of the WNRL Board and the board of directors of the general partner of Andeavor Logistics (the “Andeavor Logistics Board”), the approval of the conflicts committees established by the WNRL Board and the Andeavor Logistics Board, respectively, and the satisfaction of any conditions to the consummation of a transaction set forth in any such definitive agreement. On March 2, 2017, the requirements for the conversion of all WNRL subordinated units into common units were satisfied under the partnership agreement. As a result, the 22,811,000 subordinated units converted into common units on a one-for-one basis and thereafter participated on terms equal with all other common units in distributions of available cash. See Note 11, Equity , for additional information. On September 15, 2016, we acquired certain terminalling, transportation and storage assets from a wholly-owned subsidiary of Western consisting of the Cottage Grove tank farm and certain terminals, storage assets, pipelines and other logistics assets located at Western's St. Paul Park refinery ("St. Paul Park Logistics Assets"). The financial statements presented in this Quarterly Report on Form 10-Q have been retrospectively adjusted to include the combined financial results of the St. Paul Park Logistics Assets prior to our acquisition on September 15, 2016 (" St. Paul Park Logistics Transaction "). The historical operations of the St. Paul Park Logistics Assets prior to the St. Paul Park Logistics Transaction generally recorded operating costs and other expenses associated with storage and terminalling services and recorded no revenue. For periods subsequent to the St. Paul Park Logistics Transaction , the results of operations for the St. Paul Park Logistics Assets reflect revenues based on contractual rates set forth in our commercial agreements with Western. See Note 3, Acquisitions of Common Control Assets and Note 17, Related Party Transactions , for additional information. Our operations include two reportable segments: the logistics segment and the wholesale segment. See Note 5, Segment Information , for further discussion of our reportable segments.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	2. Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In management's opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2017 , are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 , or for any other period. We have not reported comprehensive income due to the absence of items of other comprehensive income or loss during the periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016 . The condensed consolidated financial statements do not reflect the push-down accounting of the purchase price adjustments resulting from the Andeavor Acquisition. Restricted Cash Restricted cash reported in our Condensed Consolidated Balance Sheet at June 30, 2017 relates to net proceeds from the sale of our lubricant operations located in Arizona and Nevada during the second quarter of 2017. This cash is restricted through June 30, 2018 and must be used to reinvest in assets used in our business or as a prepayment of debt. Financial Instruments and Fair Value Financial instruments that potentially subject us to concentrations of credit risk consist of accounts receivable. We believe that our credit risk is minimized as a result of the credit quality of our customer base. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, which we consider Level 1 assets, approximated their fair values at June 30, 2017 and December 31, 2016 , due to their short-term maturities. The carrying amount of our debt is the amount reflected in the Condensed Consolidated Balance Sheets, including the current portion. The fair value of the debt was determined based on prices from recent trade activity and is categorized in Level 2 of the fair value hierarchy. See Note 10, Debt , for additional information. Use of Estimates The preparation of financial statements in conformity with 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. Recent Accounting Pronouncements Effective January 1, 2017, we adopted the accounting and reporting requirements included in the Accounting Standards Codification ("ASC") for employee share-based payment accounting. We have applied the new standard prospectively, except for the cash flow considerations, which we applied retrospectively. The adoption of these revised standards was not material to our financial position or results of operations. The presentation of our Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2016 , has been retrospectively adjusted to include payments of $0.5 million for tax withholdings for stock-based compensation in net cash used in financing activities that was previously reported in net cash provided by operating activities as a change in accounts payable and accrued liabilities. Accounting Standards Update 2017-03 addresses the disclosure requirements in regards to the impact that recently issued accounting standards will have on the financial statements of a registrant when such standards are adopted in a future period. The specific impact of this guidance will be determined by the respective changes in GAAP. From time to time, new accounting pronouncements are issued by various standard setting bodies that may have an impact on our accounting and reporting. We are currently evaluating the effect that certain of these new accounting requirements may have on our accounting and related reporting and disclosures in our condensed consolidated financial statements. • Recognition and reporting of revenues - the requirements were amended to remove inconsistencies in revenue requirements and to provide a more complete framework for addressing revenue issues across a broad range of industries and transaction types. The revised standard’s core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The revised standard also addresses principal versus agent considerations and indicators related to transfer of control over specified goods. These provisions are effective January 1, 2018, and can be adopted using either a full retrospective approach or a modified approach, with early adoption permitted for periods beginning after December 15, 2016, and interim periods thereafter. We have been evaluating and continue to evaluate the provisions of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. A multi-disciplined implementation team has gained an understanding of the standard’s revenue recognition model, is reviewing and documenting our contracts, and is analyzing whether enhancements are needed to our business and accounting systems. Thus far in our review and analysis, we have not identified any material differences in our existing revenue recognition methods that would require modification under the new standard. We expect to complete this phase of our implementation plan within the next several months after which we will implement any changes to existing business processes and systems to accommodate the new standard. We will adopt this standard as of January 1, 2018. We preliminarily expect to transition to the new standard under the modified retrospective transition method, whereby a cumulative effect adjustment is recognized upon adoption and the guidance is applied prospectively. • Lease accounting - the requirements were amended with regard to recognizing lease assets and lease liabilities on the balance sheet and disclosing information about leasing arrangements. The core principle is that a lessee should recognize the assets and liabilities that arise from leases. These provisions are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We have been evaluating and continue to evaluate the provisions of this standard and its impact on our business processes, business and accounting systems, and financial statements and related disclosures. • Cash flow statement - the requirements address certain classification issues related to the statement of cash flows. These provisions are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted in any interim or annual period. • Business combinations - the requirements clarify the definition of a business and provide a framework that gives entities a basis for making reasonable judgments about whether a transaction involves an asset or a business. This guidance is effective in annual periods beginning after December 15, 2017, including interim periods therein. It must be applied prospectively on or after the effective date with early adoption permitted subject to certain requirements, and no disclosures for a change in accounting principle are required at transition.

Business Combinations [Abstract]
Mergers, Acquisitions and Dispositions Disclosures [Text Block]	3. Acquisitions of Common Control Assets On September 15, 2016 , we completed the St. Paul Park Logistics Transaction with a wholly-owned subsidiary of Western in exchange for $195 million in cash and 628,224 common units representing limited partner interests in WNRL. The St. Paul Park Logistics Assets acquired by WNRL included approximately 4.0 million barrels of refined product and crude oil storage capacity, a light products terminal, a heavy products loading rack and certain rail and barge facilities. The St. Paul Park Logistics Assets also include other related logistics assets including two crude oil pipeline segments and one pipeline segment not currently in service, each of which is 2.5 miles and extends from Western's refinery in St. Paul Park, Minnesota to Western's tank farm in Cottage Grove, Minnesota. In connection with the St. Paul Park Logistics Transaction , we entered into a terminalling, transportation and storage services agreement with Western (the " St. Paul Park Terminalling Agreement "). Pursuant to the St. Paul Park Terminalling Agreement , we agreed to provide product storage services, product throughput services and product additive and blending services at the terminal facilities located at or near Western's refinery in St. Paul Park, Minnesota. In exchange for such services, Western agreed to certain minimum volume commitments and to pay certain fees. The St. Paul Park Terminalling Agreement has an initial term of ten years, which may be extended for up to two renewal terms of five years each upon the mutual agreement of the parties. See Note 17, Related Party Transactions , for additional information.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	4. Divestitures We completed an evaluation of our lubricant operations and concluded that lubricants are not strategic to our core operations. We have taken steps to divest the remaining assets associated with our lubricant operations and have executed asset purchase agreements with third parties. On June 30, 2017, we sold our lubricant operations located in Arizona and Nevada for $14.7 million resulting in a gain on disposal of assets of $2.8 million . Due to provisions in our senior secured revolving credit facility agreement and 7.5% Senior Notes indenture, the proceeds received from the sale of our lubricant operations must be used in our business or as a prepayment of debt. Restricted cash reported in our Condensed Consolidated Balance Sheet at June 30, 2017 , was $14.3 million . This cash is restricted through June 30, 2018. We anticipate completing a sale of the remaining assets during the third quarter of 2017. In connection with the disposal of our lubricant operations, we reported employee severance costs of $0.4 million and $0.5 million within direct operating expenses and selling, general and administrative expenses in our Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2017 , respectively. Assets held for sale in our Condensed Consolidated Balance Sheet at June 30, 2017 and December 31, 2016, respectively, include $1.1 million and $10.1 million in inventories and $2.4 million and $7.3 million in property, plant and equipment. These assets and associated results from operations are presented in our Wholesale segment. During the second and third quarters of 2016, we disposed of certain assets related to our lubricant sales in California. In connection with this asset disposal, we reported employee severance costs of $0.4 million within direct operating expenses and selling, general and administrative expenses in our Condensed Consolidated Statement of Operations for the three months ended June 30, 2016. A gain of $0.6 million was included in gain on disposal of assets, net for the three and six months ended June 30, 2016 in the Condensed Consolidated Statements of Operations.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	5. Segment Information Our operations are organized into two reportable segments based on marketing criteria, the nature of our products and services and our types of customers. These segments are logistics and wholesale. Logistics. Our pipeline and gathering assets are positioned to support crude oil supply for Western's El Paso, Gallup and St. Paul Park refineries as well as third parties and consist of crude oil pipelines and gathering assets located primarily in the Delaware Basin, in the Four Corners area of Northwestern New Mexico and in the Upper Great Plains region. These systems gather and transport crude oil by pipeline from various production locations to Western’s refineries utilizing 705 miles of pipeline; 33 crude oil storage tanks with a total combined active shell storage capacity of approximately 959,000 barrels, eight truck loading and unloading locations and 15 pump stations. Our terminalling, transportation and storage assets support crude oil supply and refined product distribution for Western's El Paso, Gallup and St. Paul Park refineries as well as third parties and primarily consist of storage tanks, terminals, transportation and other assets located in El Paso, Texas; Gallup, Bloomfield and Albuquerque, New Mexico; Phoenix and Tucson, Arizona and St. Paul Park, Minnesota. These assets include crude oil, feedstock, blendstock, refined product and asphalt storage tanks with a total combined shell storage capacity of 11.4 million barrels; truck, railcar and barge loading racks; pump stations and pipeline and related logistics assets to service Western’s operations. Wholesale. Our wholesale segment includes the operations of several lubricant and bulk petroleum distribution facilities and a fleet of crude oil, refined product, asphalt and lubricant delivery trucks. Our wholesale segment distributes commercial wholesale petroleum products primarily in Arizona, Colorado, Nevada, New Mexico and Texas. The wholesale segment purchases petroleum fuels and lubricants from Western's refining segment and from third-party suppliers. Segment Accounting Principles. Operating income for each segment consists of net revenues less cost of products sold; direct operating expenses; selling, general and administrative expenses; net impact of the disposal of assets and depreciation and amortization. Activities of our business that are not included in the two segments mentioned above are included in the "Other" category. These activities consist primarily of corporate staff operations and other items that are not specific to the normal business of any one of our two reportable segments. The total assets of each segment consist primarily of cash and cash equivalents; inventories; net accounts receivable; net property, plant and equipment; net intangible assets and other assets directly associated with the individual segment’s operations.

Earnings Per Unit [Abstract]
Earnings Per Share [Text Block]	6. Earnings Per Unit Earnings in excess of distributions are allocated to the limited partners in accordance with our partnership agreement. 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 earnings per unit. Diluted earnings per unit includes the effects of potentially dilutive units of our common units that consist of unvested phantom units. These units are non-participating securities due to the forfeitable nature of their associated distribution equivalent rights, prior to vesting. We do not consider these units in the two-class method when calculating earnings per unit. Basic and diluted earnings per unit applicable to subordinated limited partners are the same because there were no potentially dilutive subordinated units outstanding. In accordance with our partnership agreement, our subordinated units converted to common units once we met specified distribution targets and successfully completed other tests set forth in our Second Amended and Restated Agreement of Limited Partnership ("Second A&R Partnership Agreement"). On March 2, 2017, the requirements for the conversion of all WNRL subordinated units into common units were satisfied under the partnership agreement. As a result, the 22,811,000 subordinated units converted into common units on a one-for-one basis and, thereafter, participated on terms equal with all other common units in distributions of available cash. The conversion of the subordinated units did not impact the amount of cash distributions paid by us or the total number of outstanding units. Refer to Note 11, Equity , for further information. In addition to the common and subordinated units, we have identified the general partner interest, incentive distribution rights and distributions associated with the TexNew Mex Units as participating securities and use the two-class method when calculating earnings per unit applicable to limited partners that is based on the weighted-average number of common units outstanding during the period. We make incentive distribution payments to our General Partner when our per unit distribution amount exceeds the target distribution. During the three and six months ended June 30, 2017 and 2016 , we made incentive distribution right payments to our General Partner of $3.1 million , $5.2 million , $0.9 million and $1.7 million , respectively. Refer to Note 11, Equity , for further information regarding incentive distribution rights. To the extent there is sufficient available cash from operating surplus under the Second A&R Partnership Agreement, the holder of the TexNew Mex Units will be entitled to receive a distribution equal to 80% of the excess of TexNew Mex Shared Segment Distributable Cash Flow over the TexNew Mex Base Amount (as such terms are defined in the Second A&R Partnership Agreement). To the extent the holder of a TexNew Mex Unit is entitled to such a distribution, that distribution will be preferential to all other unit holder distributions. During the three and six months ended June 30, 2017 and 2016 , the TexNew Mex unitholders were not entitled to any distributions. Refer to Note 11, Equity , for further information. The calculation of net income per unit for the three and six months ended June 30, 2017 and 2016 , respectively, is as follows: Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 (In thousands, except per unit data) Net income $ 18,728 $ 9,980 $ 38,614 $ 15,737 Net loss attributable to General Partner (1) — (7,894 ) — (16,144 ) Net income attributable to limited partners 18,728 17,874 38,614 31,881 General Partner distributions (3,981 ) (921 ) (7,044 ) (1,682 ) Limited partners' distributions on common units (29,252 ) (9,858 ) (49,930 ) (19,453 ) Limited partners' distributions on subordinated units — (9,181 ) (6,992 ) (18,135 ) Distributions greater than earnings $ (14,505 ) $ (2,086 ) $ (25,352 ) $ (7,389 ) General Partners' earnings: Distributions $ 3,981 $ 921 $ 7,044 $ 1,682 Net loss attributable to General Partner (1) — (7,894 ) — (16,144 ) Total General Partners' earnings (loss) $ 3,981 $ (6,973 ) $ 7,044 $ (14,462 ) Limited partners' earnings on common units: Distributions $ 29,252 $ 9,858 $ 49,930 $ 19,453 Allocation of distributions greater than earnings (14,505 ) (1,119 ) (22,205 ) (3,895 ) Total limited partners' earnings on common units $ 14,747 $ 8,739 $ 27,725 $ 15,558 Limited partners' earnings on subordinated units (2): Distributions $ — $ 9,181 $ 6,992 $ 18,135 Allocation of distributions greater than earnings — (967 ) (3,147 ) (3,494 ) Total limited partners' earnings on subordinated units $ — $ 8,214 $ 3,845 $ 14,641 Weighted-average limited partner units outstanding: Common units - basic 60,962 26,409 53,364 25,429 Common units - diluted 60,971 26,427 53,372 25,441 Subordinated units - basic and diluted — 22,811 7,562 22,811 Net income per limited partner unit: Common - basic $ 0.24 $ 0.33 $ 0.52 $ 0.61 Common - diluted 0.24 0.33 0.52 0.61 Subordinated - basic and diluted — 0.36 0.51 0.64 (1) We apply the two-class method to calculate earnings per unit and allocate the results of operations of the St. Paul Park Logistics Assets prior to the St. Paul Park Logistics Transaction entirely to our general partner. The limited partners had no rights to the results of operations before the acquisition. (2) On March 2, 2017, the 22,811,000 subordinated units converted into common units on a one-for-one basis and thereafter participated on terms equal with all other common units in distributions of available cash. Distributions greater than earnings were allocated to the subordinated units through March 2, 2017.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	10. Debt Revolving Credit Facility In connection with the St. Paul Park Logistics Transaction , on September 15, 2016, we entered into a Commitment Increase and First Amendment to Credit Agreement (the “Amendment”) to our senior secured revolving credit facility (the "Revolving Credit Facility") to bring the total commitment to $500.0 million . The Revolving Credit Facility will mature on October 16, 2018. We have the ability to increase the total commitment of our Revolving Credit Facility by up to $150.0 million for a total facility size of up to $650.0 million , subject to receiving increased commitments from lenders and to the satisfaction of certain conditions. The Revolving Credit Facility includes a $25.0 million sub-limit for standby letters of credit and a $10.0 million sub-limit for swing line loans. Obligations under the Revolving Credit Facility and certain cash management and hedging obligations are guaranteed by all of our subsidiaries and are secured by a first priority lien on substantially all of our and our subsidiaries' significant assets. Our creditors under the Revolving Credit Facility have no recourse to Western's or Andeavor's assets. Borrowings under our Revolving Credit Facility bear interest at either a base rate plus an applicable margin ranging from 0.75% to 1.75% , or at LIBOR plus an applicable margin ranging from 1.75% to 2.75% . The applicable margin will vary based on our Consolidated Total Leverage Ratio, as defined in the Revolving Credit Facility. Pursuant to the Amendment, certain existing lenders and new lenders agreed to provide incremental commitments in an aggregate principal amount of $200.0 million . In addition, the Amendment amended the Revolving Credit Facility by, among other things, (a) adding an anti-cash hoarding provision and (b) permitting the Partnership to increase the total leverage ratio permitted thereunder from 4.50 : 1.00 to 5.00 : 1.00 following any material permitted acquisition through the last day of the second full fiscal quarter following such acquisition. The incremental commitments established by the Amendment benefit from the same covenants, events of default, guarantees and security as the existing commitments under the Revolving Credit Facility. We incurred financing costs associated with the Amendment of $1.2 million . On October 30, 2015, we borrowed $145.0 million under the Revolving Credit Facility to partially fund the purchase of the TexNew Mex Pipeline system from a wholly-owned subsidiary of Western. During the year ended December 31, 2016, we repaid these direct borrowings using the net proceeds generated from our equity offering during the second quarter of 2016 and from cash-on-hand. On September 15, 2016, we borrowed $20.3 million under the Revolving Credit Facility, to partially fund the St. Paul Park Logistics Transaction . As of June 30, 2017 , the availability under the Revolving Credit Facility was $479.0 million . This availability is net of $20.3 million in direct borrowings and $0.7 million in outstanding letters of credit. We had no swing line borrowings outstanding under our Revolving Credit Facility as of June 30, 2017 . The estimated fair value of the Revolving Credit Facility approximates its carrying amount. The interest rate for the borrowings under the Revolving Credit Facility was 3.26% as of June 30, 2017 . The unamortized financing costs of $1.5 million and $2.0 million as of June 30, 2017 and December 31, 2016 , respectively, are included in long-term debt in the Condensed Consolidated Balance Sheets. The effective rate of interest, including contractual interest and amortization of loan fees, on the Revolving Credit Facility was 3.49% as of June 30, 2017 . The Revolving Credit Facility contains covenants that limit or restrict our ability to make cash distributions. We are required to maintain certain financial ratios; each tested on a quarterly basis for the immediately preceding four quarter period. We were in compliance with our debt covenants as of and for the six months ended June 30, 2017 . 7.5% Senior Notes On February 11, 2015, we entered into an Indenture (the “Indenture”) among the Partnership, WNRL Finance Corp., a Delaware corporation and 100% owned subsidiary of the Partnership (“Finance Corp.” and together with the Partnership, the “Issuers”), the Guarantors named therein and U.S. Bank National Association, as trustee (the “Trustee”) under which the Issuers issued $300.0 million in aggregate principal amount of 7.5% Senior Notes due 2023 (the "WNRL 2023 Senior Notes"). The Partnership will pay interest on the WNRL 2023 Senior Notes semi-annually in arrears on February 15 and August 15 of each year, beginning on August 15, 2015. The WNRL 2023 Senior Notes will mature on February 15, 2023. The estimated fair value of the WNRL 2023 Senior Notes was $324.0 million as of June 30, 2017 . We incurred financing costs associated with the issuance of the WNRL 2023 Senior Notes of $6.8 million . Unamortized financings costs of $4.8 million and $5.2 million as of June 30, 2017 and December 31, 2016 , respectively, are included in long-term debt in the Condensed Consolidated Balance Sheets. The effective rate of interest, including contractual interest and amortization of loan fees, on the 7.5% Senior Notes was 7.78% as of June 30, 2017 . The WNRL 2023 Senior Notes are fully and unconditionally and jointly and severally guaranteed on a senior unsecured basis by all of WNRL's current 100% owned subsidiaries, with the exception of Finance Corp. Finance Corp. is a minor subsidiary of WNRL and is a co-issuer of the WNRL 2023 Senior Notes. The co-issuance between WNRL and Finance Corp. is on a joint and several basis. WNRL has no independent assets or operations. There are no significant restrictions on the ability of WNRL or its subsidiary guarantors and Finance Corp. to obtain or transfer funds from its subsidiary guarantors by dividend or loan. None of the subsidiary guarantors’ or Finance Corp.'s assets represent restricted assets. The subsidiary guarantees of the WNRL 2023 Senior Notes are subject to certain automatic customary releases, including upon the sale, disposition or transfer of capital stock or all or substantially all of the assets (including by way of merger or consolidation) of a subsidiary guarantor to a person other than the Partnership or one of its restricted subsidiaries, designation of a subsidiary guarantor as an unrestricted subsidiary in accordance with the Indenture, a legal defeasance or covenant defeasance, liquidation or dissolution of the subsidiary guarantor and a subsidiary guarantor ceasing to guarantee debt of the Partnership, Finance Corp. or any other guarantor under a credit facility other than the WNRL 2023 Senior Notes. The Partnership’s subsidiaries may not sell or otherwise dispose of all or substantially all of their properties or assets to, or consolidate with or merge into, another company if such a sale would cause a default under the Indenture. The Indenture contains covenants that limit WNRL’s and its restricted subsidiaries’ ability to, among other things: (i) incur, assume or guarantee additional indebtedness or issue preferred units, (ii) create liens to secure indebtedness, (iii) pay distributions on equity securities, repurchase equity securities or redeem subordinated indebtedness, (iv) make investments, (v) effect distributions, loans or other asset transfers from the Partnership’s restricted subsidiaries, (vi) consolidate with or merge with or into, or sell substantially all of the Partnership’s properties to, another person, (vii) sell or otherwise dispose of assets, including equity interests in subsidiaries and (viii) enter into transactions with affiliates. These covenants are subject to a number of limitations and exceptions. The Indenture would permit or require the principal, premium, if any, and interest on all the then outstanding WNRL 2023 Senior Notes to be due and payable immediately in the event of default. We were in compliance with our debt covenants as of and for the six months ended June 30, 2017 .

Stockholders' Equity Note Disclosure [Text Block]	11. Equity We had 28,993,863 publicly held outstanding common units as of June 30, 2017 , including the net settlement and issuance of 127,386 common units upon the vesting of phantom units from our Western Refining Logistics, LP 2013 Long-Term Incentive Plan (the "LTIP") during the six months ended June 30, 2017 . Andeavor owned 32,018,847 of our common units constituting an aggregate limited partner interest of 52.5% as of June 30, 2017 . In accordance with our partnership agreement, our subordinated units converted to common units once we met specified distribution targets and successfully completed other tests set forth in our Second A&R Partnership Agreement. On March 2, 2017, the requirements for the conversion of all WNRL subordinated units into common units were satisfied under the partnership agreement. As a result, the 22,811,000 subordinated units converted into common units on a one-for-one basis and, thereafter, participated on terms equal with all other common units in distributions of available cash. The conversion of the subordinated units did not impact the amount of cash distributions paid by us or the total number of outstanding units. On September 15, 2016 , we issued 628,224 common units to Western in connection with the St. Paul Park Logistics Transaction. See Note 3, Acquisitions of Common Control Assets , for further information. On September 7, 2016, we entered into an underwriting agreement relating to the issuance and sale by the Partnership of 7,500,000 common units representing limited partner interests in the Partnership. The closing of the offering occurred on September 13, 2016. We also granted the underwriter an option to purchase additional common units on the same terms, which was exercised in full and closed on September 30, 2016, for 1,125,000 additional common units. On May 16, 2016, we entered into an underwriting agreement relating to the issuance and sale by the Partnership of 3,750,000 common units representing limited partner interests in the Partnership. The closing of the offering occurred on May 20, 2016. We also granted the underwriters an option to purchase up to 562,500 additional common units on the same terms, which was exercised in full and closed on June 1, 2016.

The TexNew Mex units are generally entitled to participate in 80% of the economics attributable to the TexNew Mex Shared Segment resulting from crude oil throughput on the TexNew Mex shared segment above 13,000 bpd. To the extent there is sufficient available cash from operating surplus under the Second A&R Partnership Agreement, the holder of the TexNew Mex Units will be entitled to receive a distribution equal to 80% of the excess of TexNew Mex Shared Segment Distributable Cash Flow over the TexNew Mex Base Amount (as such terms are defined in the Second A&R Partnership Agreement). To the extent the holder of a TexNew Mex Unit is entitled to such a distribution, that distribution will be preferential to all other unit holder distributions. We declared no distributions to TexNew Mex unitholders related to our operating results for the three and six months ended June 30, 2017 and 2016 . Holders of TexNew Mex Units generally do not have voting rights, except for limited voting rights related to amendments to the rights of holders of the TexNew Mex Units, the issuance of additional TexNew Mex Units or partnership securities with distribution rights senior to or on a parity with the TexNew Mex Units, the sale of any material portion of the TexNew Mex Pipeline and the reservation by the Partnership of any distribution amounts to which the holders of TexNew Mex Units are otherwise entitled. The TexNew Mex Units are perpetual and have no rights of redemption or conversion. No holder of any TexNew Mex Unit may transfer any or all of the TexNew Mex Units held by such holder without the prior written approval of the General Partner, unless the transfer either is to an affiliate of the holder or is to any person who is, or will be substantially concurrently with the completion of the transfer, an affiliate of the General Partner. Issuance of Additional Interests Our partnership agreement authorizes us to issue additional partnership interests for consideration and on the terms and conditions determined by our General Partner without the approval of the unitholders. We may fund future acquisitions through the issuance of additional common units or other partnership interests. Holders of any additional common units we issue will be entitled to share proportionally in accordance with their respective percentage interests with the then-existing common unitholders in our distributions of available cash. Allocations of Net Income and Loss The Second A&R Partnership Agreement contains provisions for the allocation of net income and loss to the unitholders and the General Partner. For purposes of maintaining partner capital accounts, the Second A&R 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, if any, to priority income allocations in an amount equal to incentive distribution right payments allocated 100% to the General Partner and distributions to the TexNew Mex unitholders. Percentage Allocations of Available Cash from Operating Surplus The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our General Partner (as the holder of our incentive distribution rights) based on the specified target distribution levels, subject to the preferential distribution rights of holders of the TexNew Mex Units. The amounts set forth under the column heading "Marginal Percentage Interest in Distributions" are the percentage interests of our General Partner and the unitholders in any available cash from operating surplus 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 assume our General Partner has not transferred its incentive distribution rights and there are no arrearages on common units. Total Quarterly Distribution per Unit Target Amount Marginal Percentage Interest in Distributions Unitholders General Partner Minimum Quarterly Distribution $0.2875 100.0 % — First Target Distribution above $0.2875 up to $0.3306 100.0 % — Second Target Distribution above $0.3306 up to $0.3594 85.0 % 15.0 % Third Target Distribution above $0.3594 up to $0.4313 75.0 % 25.0 % Thereafter above $0.4313 50.0 % 50.0 % Distributions Our Second A&R Partnership Agreement sets forth the calculation to be used to determine the amount and priority of cash distributions that the common unitholders and general partner will receive.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Shareholders' Equity and Share-based Payments [Text Block]	12. Equity-Based Compensation Our General Partner's board of directors adopted the LTIP for the benefit of employees, consultants and non-employee directors of our General Partner and its affiliates. Awards granted under the LTIP vest over a scheduled vesting period and their market value at the date of the grant is amortized over the restricted period on a straight-line basis. At June 30, 2017 , there were 4,111,827 WNRL common units reserved for future grants under the LTIP. The only equity awards that have been granted pursuant to the LTIP are phantom units. The fair value of the phantom units is determined based on the closing price of WNRL common units on the grant date. The estimated fair value of the phantom units is amortized on a straight-line basis over the scheduled vesting periods of individual awards. We incurred unit-based compensation expense of $3.1 million , $3.7 million , $0.8 million and $1.3 million for the three and six months ended June 30, 2017 and 2016 , respectively. Upon completion of the Andeavor Acquisition on June 1, 2017, we incurred $2.3 million of additional unit-based compensation expense due to the acceleration of certain phantom unit awards upon Western's change in control. The aggregate grant date fair value of nonvested phantom units outstanding as of June 30, 2017 , was $3.7 million . The aggregate intrinsic value of such phantom units was $3.7 million . Total unrecognized compensation cost related to our non-vested phantom units totaled $3.1 million at June 30, 2017 , which we expect to recognize over a weighted-average period of approximately 2.3 years . A summary of our unit award activity for the six months ended June 30, 2017 , is set forth below: Number of Phantom Units Weighted-Average Not vested at December 31, 2016 285,155 $ 26.42 Awards granted 52,654 24.70 Awards vested (1) (193,499 ) 26.52 Awards forfeited — — Not vested at June 30, 2017 144,310 25.65 (1) Upon completion of the Andeavor Acquisition on June 1, 2017, 107,487 phantom units vested upon Western's change in control.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	14. Income Taxes WNRL is treated as a publicly-traded partnership for federal and state income tax purposes, however, Western Refining Product Transport, LLC ("WRPT") (a wholly-owned subsidiary) is taxed as a corporation for federal and state tax purposes. Taxes on net income for WNRL and its subsidiaries generally are borne by our partners through the allocation of taxable income. The aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined as we do not have access to information about each partner's tax attributes in us. Our deferred income tax liabilities and income tax expense result from our taxable subsidiary, WRPT. In addition, tax expense is recorded as it relates to state laws that apply to entities organized as partnerships, primarily in the state of Texas. Our deferred income tax liability as of June 30, 2017 and December 31, 2016 was $0.1 million and $0.6 million , respectively. For the three and six months ended June 30, 2017 and 2016 , we had an income tax benefit of $0.3 million and $0.4 million and income tax expense of $0.2 million and $0.5 million , respectively. Our effective tax rates for the three and six months ended June 30, 2017 and 2016 , were (1.4)% , (0.9)% , 2.1% and 2.9% , respectively. As of June 30, 2017 and December 31, 2016 , we had no unrecognized tax benefit liability. No interest or penalties were recognized related to income taxes during the three and six months ended June 30, 2017 and 2016 .

Commitments Disclosure [Text Block]	15. Commitments We have commitments under various operating leases with initial terms greater than one year for property, machinery and facilities. These leases have terms that will expire on various dates through 2026 . We expect that in the normal course of business, these leases will be renewed or replaced by other leases. Rent expense for operating leases that provide for periodic rent escalations or rent holidays over the term of the lease is recognized on a straight-line basis. We also have commitments to purchase minimum volumes of refined product from Western under commercial agreements that we have entered into with Western. See Note 17, Related Party Transactions , for further discussion of these agreements. The following table presents our annual minimum rental payments under non-cancelable operating leases that have lease terms of one year or more (in thousands) as of June 30, 2017 : Remaining 2017 $ 3,320 2018 4,568 2019 2,376 2020 702 2021 349 2022 and thereafter 369 $ 11,684 Total rental expense was $2.1 million , $4.1 million , $2.4 million and $4.9 million for the three and six months ended June 30, 2017 and 2016 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Contingencies Disclosure [Text Block]	16. Contingencies Like other operators of petroleum-related storage and transportation facilities, our operations are subject to extensive and periodically changing federal and state environmental regulations governing air emissions, wastewater discharges and solid and hazardous waste management activities. Many of these regulations are becoming increasingly stringent and we expect the cost of compliance to increase over time. Our policy is to accrue environmental and clean-up related costs of a non-capital nature when it is probable that a liability exists and when we can reasonably estimate the amount. We may revise such estimates in the future as regulations and other conditions change. We may receive communications from various federal, state and local governmental authorities asserting violations of environmental laws and/or regulations. These governmental entities may also propose or assess fines or require corrective action for such asserted violations. We intend to respond in a timely manner to all such communications and to take appropriate corrective action. We are not currently aware of any environmental or other asserted or unasserted claims against us that would be expected to have a material effect on our financial condition, results of operations or cash flows.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	17. Related Party Transactions Certain of our employees are shared employees with Western and Andeavor. At the closing of our initial public offering, we entered into a services agreement with Western under which Western agreed to share certain employees with us. These employees are responsible for operation, maintenance and other services related to the assets we own and operate. Western employees provide these services under our direction, supervision and control pursuant to this services agreement. Western also provides us with support for accounting, legal, human resources and various other administrative functions. We have incurred charges from Western for the allocation of services including executive oversight, accounting, treasury, tax, legal, procurement, engineering, logistics, maintenance, information technology and similar items. We classify these charges between operating and maintenance expenses and selling, general and administrative expenses based on the functional nature of the employee and other services that Western provides for our operations. Charges from Western that we include within our selling, general and administrative and operating and maintenance expenses were as follows: Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 (In thousands) Operating and maintenance expenses $ 17,933 $ 15,667 $ 35,439 $ 31,633 Selling, general and administrative expenses 3,063 2,346 6,081 4,461 Total charges $ 20,996 $ 18,013 $ 41,520 $ 36,094 Our management believes the charges allocated to us from Western are a reasonable reflection of the utilization of Western's service to our operations. We also incur direct charges to our operations and administration. The allocations noted above may not fully reflect the additional expenses that we would have incurred had we been a stand-alone company during the periods presented. Commercial Agreements with Western Logistics Segment Agreements We derive substantially all of our logistics revenues from ten-year, fee-based agreements with Western supported by minimum volume commitments and annual adjustments to fees that we and Western may renew for two additional five-year periods upon mutual agreement. Western has committed to provide us with minimum fees based on minimum monthly throughput volumes of crude oil and refined and other products and reserved storage capacity. Pipeline and Gathering Services Agreement We are party to a pipeline and gathering services agreement, as amended, with Western under which we transport crude oil on our Permian Basin system primarily for use at Western's El Paso refinery and on our Four Corners system to Western's Gallup refinery. We charge Western fees for pipeline movements, truck offloading and product storage. WNRL entered into an amendment to the Pipeline Agreement which, among other things, amends the scope of the existing agreement to include the provision of storage services and a minimum volume commitment of 80,000 barrels of storage at the Star Lake storage tank. In the amendment to the Pipeline Agreement, Western also agreed to provide a minimum volume commitment of 13,000 bpd of crude oil on the TexNew Mex Pipeline for 10 years from the date of the amendment to the Pipeline Agreement. The General Partner adopted certain amendments to the First Amended and Restated Agreement of Limited Partnership of the Partnership by adopting the Second A&R Partnership Agreement. The amendments contained in the Second A&R Partnership Agreement create a new class of limited partner interests in the Partnership, referred to as the TexNew Mex Units, and set forth the rights, preferences and obligations of the TexNew Mex Units. The Second A&R Partnership Agreement provides for the creation of the “TexNew Mex Shared Segment” that will reflect the financial and operating results of the TexNew Mex Pipeline. The TexNew Mex Units are generally entitled to participate in 80% of the economics attributable to the TexNew Mex Shared Segment resulting from crude oil throughput on the TexNew Mex shared segment above 13,000 bpd. To the extent there is sufficient available cash from operating surplus under the Second A&R Partnership Agreement, the holder of the TexNew Mex Units will be entitled to receive a distribution equal to 80% of the excess of TexNew Mex Shared Segment Distributable Cash Flow over the TexNew Mex Base Amount (as such terms are defined in the Second A&R Partnership Agreement). To the extent the holder of a TexNew Mex Unit is entitled to such a distribution, that distribution will be preferential to all other unit holder distributions. Terminalling, Transportation and Storage Services Agreements Southwest We entered into a terminalling, transportation and storage services agreement, as amended, with Western under which we have agreed to, among other things, distribute products produced at Western’s refineries, connect Western’s refineries to third-party pipelines and systems and provide fee-based asphalt terminalling and processing services. At our network of crude oil and refined products terminals and related assets and storage facilities, we charge Western fees for crude oil, blendstock and refined product storage, shipments into and out of storage and additive and blending services. At our asphalt plant and terminal in El Paso and our three stand-alone asphalt terminals, we charge Western fees for asphalt storage, shipments into and out of asphalt storage and asphalt processing and blending. St. Paul Park In connection with the St. Paul Park Logistics Transaction , we entered into the St. Paul Park Terminalling Agreement . Pursuant to the St. Paul Park Terminalling Agreement , we agreed to provide product storage services, product throughput services and product additive and blending services at the terminal facilities located at or near Western's refinery in St. Paul Park, Minnesota. In exchange for such services, Western has agreed to certain minimum volume commitments and to pay certain fees. The St. Paul Park Terminalling Agreement has an initial term of ten years, which may be extended for up to two renewal terms of five years each upon the mutual agreement of the parties. Wholesale Segment Agreements We entered into the following 10-year agreements with Western. These agreements include certain minimum volume commitments by Western. Product Supply Agreement Under the product supply agreement, as amended, Western supplies, and we purchase, approximately 79,000 bpd of refined products. The price per barrel is based upon OPIS or Platts indices on the day of delivery. Pricing is subject to annual revision based on mutual agreement between us and Western. The agreement provides for make-up payments to us in any month that our average margin on non-delivered rack sales is less than a certain amount. Fuel Distribution and Supply Agreement Western agreed to purchase all of its retail requirements for branded and unbranded motor fuels for its retail and unmanned fleet fueling sites at a price per gallon that is $0.03 above our cost. Western purchases a minimum of 645,000 barrels per month of branded and unbranded motor fuels for its retail and unmanned fleet fueling sites. In any month that Western doesn’t purchase the minimum volume, Western pays us $0.03 per gallon shortfall. In any month in which Western purchases volumes in excess of the minimum, we pay Western $0.03 per gallon over the minimum until the balance of the trailing twelve month shortfall payments is reduced to $0 . Crude Oil Trucking Transportation Services Agreement Under the crude oil trucking and transportation services agreement, as amended, Western pays a flat rate per mile per barrel plus monthly fuel adjustments and customary applicable surcharges. The rates are subject to adjustment annually based on mutual agreement between us and Western. Western has agreed to contract a minimum of 1.525 million barrels of crude oil to us for hauling each month. Asphalt Trucking Transportation Services Agreement Our wholesale segment operates a fleet of asphalt trucks, which are utilized to deliver asphalt to Western's asphalt terminals and third party customers. We have entered into an asphalt trucking transportation services agreement with Western under which we have agreed to, among other things, transport and deliver asphalt from the El Paso refinery to asphalt terminals in Texas, New Mexico and Arizona. Volumes of asphalt transported pursuant to this agreement will be credited, on a barrel per barrel basis, towards Western’s contract minimum under the Crude Oil Trucking Transportation Services Agreement. Under this Agreement, Western has given us the first option to transport all asphalt volumes Western transports by truck. In exchange for the transportation services performed under the asphalt trucking transportation agreement, Western has agreed to pay us a flat rate per ton (with market adjustments) based on the distance between the applicable pick-up and delivery points, plus monthly fuel adjustments and customary applicable surcharges. Western’s obligations under these commercial agreements will not terminate if Western no longer controls our general partner. Our commercial agreements include provisions that permit Western to suspend, reduce or terminate its obligations under the applicable agreement if certain events occur. These events include Western deciding to permanently or indefinitely suspend refining operations at one or all of its refineries, as well as our being subject to certain force majeure events that would prevent us from performing required services under the applicable agreement. Other Agreements with Western Omnibus Agreement We entered into an omnibus agreement with Western, certain of its subsidiaries and our general partner. The omnibus agreement addresses the following items: • our obligation to reimburse Western for the provision by Western of certain general and administrative services (this reimbursement is in addition to certain expenses of our general partner and its affiliates that are reimbursed under our partnership agreement and services agreement), as well as certain other direct or allocated costs and expenses incurred by Western on our behalf; • our rights of first offer to acquire certain logistics assets from Western; • an indemnity by Western for certain environmental and other liabilities, and our obligation to indemnify Western for events and conditions associated with the operation of our assets that occur after closing of the Offering and for environmental liabilities related to our assets to the extent Western is not required to indemnify us; • Western’s transfer of certain environmental permits related to our assets to us and our use of such permits prior to the transfer thereof; and • the granting of a license from Western to us with respect to use of certain Western trademarks and our granting of a license to Western with respect to use of certain of our trademarks. The omnibus agreement generally terminates in the event of a change of control of us or our general partner. Contribution, Conveyance and Assumption Agreement dated September 7, 2016 We entered into a Contribution, Conveyance and Assumption Agreement with Western under which WNRL acquired approximately 4.0 million barrels of refined product and crude oil storage tanks, a light products terminal, a heavy products loading rack, certain rail and barge facilities, certain other related logistics assets, and two crude oil pipeline segments and one pipeline segment not currently in service, each of which is approximately 2.5 miles and extends from Western's refinery in St. Paul Park, Minnesota to Western’s tank farm in Cottage Grove, Minnesota. Western made certain representations and warranties regarding the acquired assets, including with respect to environmental matters, and agreed to indemnify us for breaches of those representations and warranties, subject to specified deductibles, caps and other limitations. Contribution, Conveyance and Assumption Agreement dated October 30, 2015 We entered into a Contribution, Conveyance and Assumption Agreement with Western under which we acquired (i) a segment of the TexNew Mex Pipeline system that currently extends from our crude oil station in Star Lake, New Mexico, in the Four Corners region, to our T station in Eddy County, New Mexico, and (ii) an 80,000 barrel crude oil storage tank located at our crude oil pumping station in Star Lake, New Mexico and certain other related assets (the “TexNew Mex Pipeline Acquisition”). Western made certain representations and warranties regarding the acquired assets, including with respect to environmental matters, and agreed to indemnify us for breaches of those representations and warranties, subject to specified deductibles, caps and other limitations. Contribution, Conveyance and Assumption Agreement dated September 25, 2014 We entered into a contribution agreement with Western on September 25, 2014 under which we acquired all of the outstanding limited liability company interests of Western Refining Wholesale, LLC (“WRW”), which owned substantially all of Western’s southwest wholesale assets. Among other things, Western agreed to indemnify us with respect to liabilities related to certain historical assets and operations of WRW that were not contributed to us in our acquisition of WRW. In addition, Western made certain representations and warranties regarding the assets of WRW, including with respect to environmental matters, and agreed to indemnify us for breaches of those representations and warranties, subject to specified deductibles, caps and other limitations. Services Agreements We entered into a services agreement with Western under which we reimburse Western for its provision to us of certain personnel to provide operational services to us and under our supervision in support of our pipelines and gathering assets and terminalling and storage facilities, including routine and emergency maintenance and repair services, routine operational activities, routine administrative services, construction and related services and such other services as we and Western may mutually agree upon from time to time. Western will prepare a maintenance, operating and capital budget on an annual basis subject to our approval. Western submits actual expenditures for reimbursement on a monthly basis, and we reimburse Western for providing these services. We may terminate any of the services provided by the personnel provided by Western upon 30 days prior written notice. Either party may terminate this agreement upon prior written notice if the other party is in material default under the agreement and such party fails to cure the material default within 20 business days. The services agreement has an initial term of ten years and may be renewed by two additional five-year terms upon our agreement with Western evidenced in writing prior to the end of the initial term of ten years or the first renewal term of five years. If a force majeure event prevents a party from carrying out its obligations (other than to make payments due) under the agreement, such obligations, to the extent affected by force majeure, will be suspended during the continuation of the force majeure event. These force majeure events include acts of God, strikes, lockouts or other industrial disturbances, wars, riots, fires, floods, storms, orders of courts or governmental authorities, explosions, terrorist acts, accidental disruption of service, breakage, breakdown of machinery, storage tanks or lines of pipe and inability to obtain or unavoidable delays in obtaining material or equipment and any other circumstances not reasonably within the control of the party claiming suspension and that by the exercise of due diligence such party is unable to prevent or overcome. On May 4, 2015, we entered into a Joinder Agreement with Western and Northern Tier Energy LP ("NTI") that joined us as a party to the Shared Services Agreement, dated October 30, 2014, between Western and NTI and under which Western and NTI provide services to each other in support of their operations. Under the Joinder Agreement, we provide certain scheduling and other services in support of NTI’s operations and NTI reimburses us for the costs associated with providing such services. During the three and six months ended June 30, 2017 and 2016 , we incurred expenses of $0.2 million , $0.4 million , $0.1 million and $0.2 million , respectively, that are reimbursable from NTI under the Shared Services Agreement. Leasing Agreements We entered into three separate ground lease and access agreements with Western. All three agreements are for 10-year terms with provision for automatic renewal of up to four consecutive 10-year periods. Under each separate agreement, WNRL pays nominal annual rents. Rents due under these three agreements in the aggregate are less than $0.1 million over the initial term of the agreements.
