Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	ORGANIZATION AND BASIS OF PRESENTATION ORGANIZATION Tesoro Logistics LP (“TLLP” or the “Partnership”) is a fee-based, growth-oriented Delaware limited partnership formed in December 2010 by Tesoro Corporation and its wholly-owned subsidiary, Tesoro Logistics GP, LLC (“TLGP”), our general partner, to own, operate, develop and acquire logistics assets. Unless the context otherwise requires, references in this report to “we,” “us,” “our,” or “ours” refer to Tesoro Logistics LP, one or more of its consolidated subsidiaries, or all of them taken as a whole. Unless the context otherwise requires, references in this report to “Tesoro” or our “Sponsor” refer collectively to Tesoro Corporation and any of its subsidiaries, other than TLLP, its subsidiaries and its general partner. PRINCIPLES OF COMBINATION AND CONSOLIDATION AND BASIS OF PRESENTATION Acquired assets from Tesoro, and the associated liabilities and results of operations are collectively referred to as the “Predecessors.” See Note 2 for further discussion of acquisitions from Tesoro. The accompanying condensed combined consolidated financial statements and related notes present the financial position, results of operations and cash flows of our Predecessors at historical cost. The financial statements of our Predecessors have been prepared from the separate records maintained by Tesoro and may not necessarily be indicative of the conditions that would have existed or the results of operations if our Predecessors had been operated as a stand-alone business. Our Predecessors did not record revenue for transactions with Tesoro and the expenses recognized were not material in the Terminalling and Transportation segment. Tesoro retained any current assets and current liabilities related to the Alaska Storage and Terminalling Assets as of the dates of the acquisition. The interim condensed combined consolidated financial statements and notes thereto have been prepared by management without audit according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. However, management believes that the disclosures presented herein are adequate to present the information fairly. The accompanying interim condensed combined consolidated financial statements and notes should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2015 . We prepare our condensed combined consolidated financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the amounts of assets and liabilities and revenues and expenses reported as of and during the periods presented. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ from those estimates. The results of operations of the Partnership, or our Predecessors, for any interim period are not necessarily indicative of results for the full year. CONDENSED CONSOLIDATING FINANCIAL INFORMATION. The parent company of the Partnership’s operations, Tesoro Logistics LP, has no independent assets or operations. The Partnership’s operations are conducted by its wholly-owned guarantor subsidiaries, other than Tesoro Logistics Finance Corp., an indirect wholly-owned subsidiary of the Partnership whose sole purpose is to act as co-issuer of any debt securities. The guarantees are full and unconditional and joint and several, subject to certain automatic customary releases, including sale, disposition, or transfer of the capital stock or substantially all of the assets of a subsidiary guarantor, exercise of legal defeasance option or covenant defeasance option, and designation of a subsidiary guarantor as unrestricted in accordance with the applicable indenture. There are no significant restrictions on the ability of the Partnership or any guarantor to obtain funds from its subsidiaries by dividend or loan. None of the assets of the Partnership or a guarantor represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act. As of September 30, 2016 , Tesoro Alaska Terminals LLC, which the Partnership acquired from Tesoro as discussed further in Note 2, had not been designated as a guarantor subsidiary. No consolidating financial statements have been presented as the assets, equity and results of operations of this entity were minor in accordance with Rule 3-10(h)(6) of Regulation S-X under the Securities Act as of and for the periods ended September 30, 2016 . Subsequent to the deconsolidation of Rendezvous Gas Services, L.L.C. (“RGS”) as of January 1, 2016, we are not required to provide condensed consolidating financial information pursuant to Rule 3-10 of Regulation S-X as we only have a minor consolidated non-guarantor subsidiary. For further discussion on the deconsolidation of RGS, see discussion below and in Note 4. FAIR VALUE INFORMATION We believe the carrying value of our cash and cash equivalents, receivables, accounts payable and certain accrued liabilities approximates fair value. Our fair value assessment incorporates a variety of considerations, including: • the short term duration of the instruments (less than one percent of our trade payables and approximately one percent of our trade receivables have been outstanding for greater than 90 days ); and • the expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk. The computation of the percentage of the short-term duration of our trade receivables excludes amounts that are greater than 90 days related to the XTO Energy Inc.’s (“XTO”) legal dispute with QEP Field Services, LLC (“QEPFS”). See further discussion regarding the XTO litigation in Note 6. The fair value of our senior notes is based on prices from recent trade activity and is categorized in level 2 of the fair value hierarchy. The borrowings under our amended secured revolving credit facility (the “Revolving Credit Facility”) and our secured dropdown credit facility (“Dropdown Credit Facility”), which include a variable interest rate, approximate fair value. The carrying value and fair value of our debt were approximately $3.4 billion and $3.6 billion as of September 30, 2016 , respectively. The carrying value and fair value of our debt were approximately $2.9 billion and $2.8 billion at December 31, 2015 , respectively. These carrying and fair values of our debt do not consider the unamortized issuance costs, which are netted against our total debt. NEW ACCOUNTING STANDARDS AND DISCLOSURES REVENUE RECOGNITION. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), and has since amended the standard with ASU 2015-14, “Deferral of the Effective Date,” ASU 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU 2016-10, “Identifying Performance Obligations and Licensing,” and ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients.” These standards provide accounting guidance for all revenue arising from contracts to provide goods or services to customers. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2017. Early adoption as of January 1, 2017 is permitted; however, we do not intend to adopt early. The standard allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of the standard on our financial statements and related disclosures. Based on our initial evaluation, the adoption of the standard is not expected to have a material impact on the amount or timing of revenue recognized. CONSOLIDATION. In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis” (“ASU 2015-02”). This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for interim and annual periods beginning after December 15, 2015, and requires either a retrospective or a modified retrospective approach to adoption. We adopted this guidance using the modified retrospective approach as of January 1, 2016 and performed the required reassessments outlined by the guidance. For further information on the results of the reassessments, refer to Note 4, Investments - Equity Method and Joint Ventures. BUSINESS COMBINATIONS. In September 2015, the FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). The standard requires an acquirer to recognize the cumulative impact of adjustments to provisional purchase price amounts that are identified during the measurement period in the reporting period, in which the adjustment amounts are determined. The standard also requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for interim and annual periods beginning after December 15, 2015 and must be applied prospectively to adjustments that occur after the effective date. We adopted this guidance as of January 1, 2016, with no impact to our financial statements. LEASES. In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”), which improves transparency and comparability among organizations by requiring lessees to recognize a lease liability and a corresponding lease asset for virtually all lease contracts. It also requires additional disclosures about leasing arrangements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and requires a modified retrospective approach to adoption. Early adoption is permitted. At this time, we are evaluating the potential impact of this standard on our financial statements. SHARE-BASED COMPENSATION. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions including accounting for income taxes, cash flow presentation of tax impacts, forfeitures, and liability versus equity accounting due to statutory tax withholding requirements. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. As of January 1, 2016, we early adopted ASU 2016-09 and with respect to the guidance on forfeitures, we have elected to continue to estimate forfeitures on the date of grant to account for the estimated number of awards for which the requisite service period will not be rendered. The adoption of ASU 2016-09 had no impact on our financial statements. STATEMENT OF CASH FLOWS. In August 2016, the FASB issued ASU 2016-15, “Clarification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented, unless deemed impracticable, in which case, prospective application is permitted. At this time, we are evaluating the potential impact of this standard on our financial statements.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure	RELATED-PARTY TRANSACTIONS ACQUISITIONS ALASKA STORAGE AND TERMINALLING ASSETS PURCHASE. Effective July 1, 2016 , the Partnership entered into an agreement to purchase certain terminalling and storage assets owned by Tesoro for total consideration of $444 million and was completed in two phases. On July 1, 2016 , the Partnership completed the acquisition of the first phase consisting of tankage with a shell capacity of approximately 3.5 million barrels, related equipment and ancillary facilities used for the operations at Tesoro’s Kenai Refinery. The second phase was completed on September 16, 2016 and consisted of refined product terminals in Anchorage and Fairbanks (together, the “Alaska Storage and Terminalling Assets”). Consideration paid for the first phase was $266 million , comprised of approximately $240 million in cash, financed with borrowings under the Dropdown Credit Facility, and the issuance of equity to Tesoro with a fair value of $26 million . Consideration paid for the second phase was $178 million , comprised of approximately $160 million in cash, financed with borrowings under the Dropdown Credit Facility, and the issuance of equity to Tesoro with a fair value of $18 million . AFFILIATE AGREEMENTS The Partnership has various long-term, fee-based commercial agreements with Tesoro, under which we provide pipeline transportation, trucking, terminal distribution and storage services to Tesoro, and Tesoro typically commits to fixed fees or to provide us with minimum monthly throughput volumes of crude oil and refined products. For the natural gas liquids that we handle under keep-whole agreements, the Partnership has a fee-based processing agreement with Tesoro which minimizes the impact of commodity price movements during the annual period subsequent to renegotiation of terms and pricing each year. In addition, we have agreements for the provision of various general and administrative services by Tesoro. Under our partnership agreement, we are required to reimburse TLGP and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended omnibus agreement (the “Amended Omnibus Agreement”) or our secondment agreement (the “Secondment Agreement”), TLGP determines the amount of these expenses. The Amended Omnibus Agreement and the Secondment Agreement were amended and restated in connection with the Alaska Storage and Terminalling Assets purchase. Under the terms of the Amended Omnibus Agreement as of September 30, 2016 , we are required to pay Tesoro an annual corporate services fee of $10 million for the provision of various centralized corporate services, including executive management, legal, accounting, treasury, human resources, health, safety and environmental, information technology, certain insurance coverage, administration and other corporate services. Under the terms of our Secondment Agreement as of September 30, 2016 , we pay Tesoro a net annual service fee of $2 million for services performed by field-level employees at the majority of our facilities. Additionally, pursuant to the Amended Omnibus Agreement and Secondment Agreement, we reimburse Tesoro for any direct costs actually incurred by Tesoro in providing other operational services with respect to certain of our other assets and operations.

PREDECESSOR TRANSACTIONS. Related-party transactions of our Predecessors were settled through equity. Our Predecessors did not record revenue for transactions with Tesoro in the Terminalling and Transportation segment. DISTRIBUTIONS. In accordance with our partnership agreement, the unitholders of our common and general partner interests are entitled to receive quarterly distributions of available cash. During the nine months ended September 30, 2016 , we paid quarterly cash distributions of $175 million to Tesoro and TLGP, including incentive distribution rights (“IDRs”). On October 18, 2016 , we declared a quarterly cash distribution of $0.875 per unit, which will be paid on November 14, 2016 . The distribution will include payments of $71 million to Tesoro and TLGP, including IDRs.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments and Joint Ventures	INVESTMENTS - EQUITY METHOD AND JOINT VENTURES For each of the following investments, we have the ability to exercise significant influence over each of these investments through our participation in the management committees, which make all significant decisions. However, since we have equal or proportionate influence over each committee as a joint interest partner and all significant decisions require consent of the other investor(s) without regard to our economic interest, we have determined that these entities should not be consolidated and apply the equity method of accounting with respect to our investments in each entity. • RGS. We have a 78% interest in RGS, which owns and operates the infrastructure that transports gas from certain fields to several re-delivery points in southwestern Wyoming, including natural gas processing facilities that are owned by us or a third party. Prior to 2016, we consolidated RGS, however, upon our reassessment performed in conjunction with the adoption of ASU 2015-02 as of January 1, 2016, we determined RGS represents a variable interest entity to us for which we are not the primary beneficiary. Under the limited liability company agreement, we do not have voting rights commensurate with our economic interest due to veto rights available to our partner in RGS. Certain business decisions, including, but not limited to, decisions with respect to significant expenditures or contractual commitments, annual budgets, material financings, dispositions of assets or amending the members’ gas servicing agreements, require unanimous approval of the members. For amounts previously consolidated in our financial statements as of and for the year ended December 31, 2015, refer to the amounts shown in the Non-Guarantor column in the condensed consolidating financial information presented in Note 16 in our annual report on Form 10-K referenced herein. • THREE RIVERS GATHERING, LLC (“TRG”). We own a 50% interest in TRG which operates natural gas gathering assets within the southeastern Uinta Basin and is primarily supported by long-term, fee-based gas gathering agreements with minimum volume commitments. • UINTAH BASIN FIELD SERVICES, L.L.C. (“UBFS”). We own a 38% interest in UBFS which owns and operates the natural gas gathering infrastructure located in the southeastern Uinta Basin and is supported by long-term, fee-based gas gathering agreements that contain firm throughput commitments, which generate fees whether or not the capacity is used, and is operated by us.

REVOLVING CREDIT FACILITY AND DROPDOWN CREDIT FACILITY AVAILABLE CAPACITY UNDER CREDIT FACILITIES (in millions) Total Capacity Amount Borrowed as of September 30, 2016 Outstanding Letters of Credit Available Capacity Expiration TLLP Revolving Credit Facility $ 600 $ — $ — $ 600 January 29, 2021 TLLP Dropdown Credit Facility 1,000 400 — 600 January 29, 2021 Total Credit Facilities $ 1,600 $ 400 $ — $ 1,200 We amended our existing secured Revolving Credit Facility on January 29, 2016 , decreasing the aggregate available facility limit from $900 million to $600 million and revised terms related to pricing and financial covenants. As a result of this amendment, an immaterial amount of unamortized debt issuance costs were expensed. In addition, we syndicated a $1.0 billion secured Dropdown Credit Facility on January 29, 2016 . The primary use of proceeds under this facility will be to fund asset acquisitions. The terms, covenants and restrictions under this facility are substantially the same as with our amended secured Revolving Credit Facility. The total aggregate available facility limits for the secured Revolving Credit Facility and secured Dropdown Credit Facility totaled $1.6 billion at September 30, 2016 . We are allowed to request the loan availability for both the secured Revolving Credit Facility and the secured Dropdown Credit Facility be increased up to an aggregate of $2.1 billion , subject to receiving increased commitments from the lenders. As of September 30, 2016 , our secured Revolving Credit Facility provided for total loan availability of $600 million . Borrowings are available under the secured Revolving Credit Facility up to the total loan availability of the facility. Our secured Revolving Credit Facility is non-recourse to Tesoro, except for TLGP, and is guaranteed by all of our consolidated subsidiaries, and secured by substantially all of our assets. We had no borrowings outstanding under the secured Revolving Credit Facility, resulting in the full loan availability of the borrowing capacity as of September 30, 2016 . As of September 30, 2016 , our secured Dropdown Credit Facility provided for total loan availability of $1.0 billion . We had $400 million borrowings outstanding under the secured Dropdown Credit Facility, resulting in unused loan availability of $600 million or 60% the borrowing capacity as of September 30, 2016 . The weighted average interest rate for borrowings under our secured Dropdown Credit Facility was 2.54% at September 30, 2016 . The secured Revolving Credit Facility and the secured Dropdown Credit Facility ratably share collateral comprised primarily of our property, plant, and equipment and both facilities mature on January 29, 2021 . In addition, upon an upgrade of our corporate family rating to investment grade from either Moody's Investors Service or S&P Global Ratings, certain covenants and restrictions under each facility will automatically be eliminated or improved. SENIOR NOTES ISSUANCE On May 9, 2016 , we completed a registered offering of $250 million aggregate principal amount of 6.125% Senior Notes due 2021 (“2021 Notes”) and $450 million aggregate principal amount of 6.375% Senior Notes due 2024 (“2024 Notes”). We used the proceeds of the offering of the 2021 notes to repay amounts outstanding under our Dropdown Credit Facility and the proceeds of the offering of the 2024 notes to repay amounts outstanding under our Revolving Credit Facility and for general partnership purposes. The 2021 Notes were issued under the same indenture governing the existing $550 million of the 6.125% Senior Notes due 2021 issued in August 2013 and have the same terms as those senior notes. The 2021 Notes have no sinking fund requirements. The 2021 Notes may be redeemed at premiums equal to 4.594% through October 15, 2017; 3.063% from October 15, 2017 through October 15, 2018; 1.531% from October 15, 2018 through October 15, 2019; and at par thereafter, plus accrued and unpaid interest. The 2021 Notes are unsecured and guaranteed by all of our subsidiaries, except Tesoro Logistics Finance Corp., the co-issuer, and are non-recourse to Tesoro, except for TLGP, and contain customary terms, events of default and covenants for an issuance of non-investment grade securities. The 2024 Notes have no sinking fund requirements. We may redeem some or all of the 2024 Notes, prior to May 1, 2019, at a make-whole price plus accrued and unpaid interest, if any. On or after May 1, 2019, the 2024 Notes may be redeemed at premiums equal to 4.781% through May 1, 2020; 3.188% from May 1, 2020 through May 1, 2021; 1.594% from May 1, 2021 through May 1, 2022; and at par thereafter, plus accrued and unpaid interest. We will have the right to redeem up to 35% of the aggregate principal amount at 106.375% face value with proceeds from certain equity issuances through May 1, 2019. The 2024 Notes are unsecured and guaranteed by all of our subsidiaries, except Tesoro Logistics Finance Corp., the co-issuer, and are non-recourse to Tesoro, except for TLGP, and contain customary terms, events of default and covenants for an issuance of non-investment grade securities. DEBT REPAYMENTS On February 3, 2016 , we paid the full amount of the Unsecured Term Loan Facility, including accrued interest, with proceeds drawn from the secured Dropdown Credit Facility. All commitments under the Unsecured Term Loan Facility were terminated effective with the repayment and an immaterial amount of unamortized debt issuance costs were expensed. SENIOR NOTES EXCHANGE On February 26, 2016 , the Partnership commenced an offer to exchange (the “Exchange”) its existing unregistered 5.50% Senior Notes due 2019 (“2019 Notes”) and 6.25% Senior Notes due 2022 (“2022 Notes”) (together, “Unregistered Notes”) for an equal principal amount of 5.50% Senior Notes due 2019 and 6.25% Senior Notes due 2022 (the “Exchange Notes”), respectively, that were registered under the Securities Act of 1933, as amended. On April 14, 2016 , the Exchange was completed for all of the 2019 Notes and substantially all of the 2022 Notes. The terms of the Exchange Notes are identical in all material respects (including principal amount, interest rate, maturity and redemption rights) to the Unregistered Notes for which they were exchanged, except that the Exchange Notes generally are not subject to transfer restrictions. The Exchange fulfills all of the requirements of the registration rights agreements for the Unregistered Notes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES TESORO INDEMNIFICATION Under the Amended Omnibus Agreement, Tesoro indemnifies us for certain matters, including known environmental, title and tax matters associated with the ownership of our assets at or before the closing of the TLLP initial public offering (“Initial Offering”) and subsequent acquisitions from Tesoro, excluding certain Los Angeles assets acquired from Tesoro in 2013. Under the Carson Assets Indemnity Agreement, Tesoro retained responsibility for remediation of known environmental liabilities due to the use or operation of certain Los Angeles assets prior to the acquisition dates, and has indemnified the Partnership for any losses incurred by the Partnership arising out of those remediation obligations. Environmental matters discovered subsequent to the Initial Offering and subsequent acquisitions are also indemnified to the extent they are identified prior to five years from the acquisition date. The indemnification under the Initial Offering for unknown environmental matters expired on April 26, 2016. See Note 3 of our Annual Report on Form 10-K for the year ended December 31, 2015 , for additional information regarding the terms and conditions of the Amended Omnibus Agreement and the Carson Assets Indemnity Agreement. CONTINGENCIES In the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations, including environmental, regulatory and other matters. The outcome of contingencies cannot always be predicted accurately, but we will accrue liabilities for these matters if the amount is probable and can be reasonably estimated. Contingencies arising after the closing of the Initial Offering from conditions existing before the Initial Offering, and the subsequent acquisitions from Tesoro that have been identified after the closing of each transaction, will be recorded in accordance with the indemnification terms set forth in the Amended Omnibus Agreement and the Carson Assets Indemnity Agreement, as noted above. Any contingencies arising from events after the Initial Offering, and the subsequent acquisitions from Tesoro, will be our responsibility. Other than described in this Note 6, we do not have any other material outstanding lawsuits, administrative proceedings or governmental investigations. ENVIRONMENTAL LIABILITIES We are subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remedy the effect of the disposal or release of specified substances at current and former operating sites. We have accrued liabilities for these expenses and believe these accruals are adequate based on current information and projections that can be reasonably estimated. Our environmental liabilities are estimates using internal and third-party assessments and available information to date. It is possible that these estimates will change as more information becomes available. Our liabilities for these environmental expenditures totaled $18 million and $33 million at September 30, 2016 and December 31, 2015 , respectively. TIOGA, NORTH DAKOTA CRUDE OIL PIPELINE RELEASE. In September 2013 , the Partnership responded to the release of crude oil in a rural field northeast of Tioga, North Dakota (the “Crude Oil Pipeline Release”). The environmental liabilities related to the Crude Oil Pipeline Release include amounts estimated for remediation activities that will be conducted to restore the site for agricultural use. This incident was covered by our pollution legal liability insurance policy, subject to a $1 million deductible and a $25 million loss limit. Pursuant to this policy, we have received all insurance recoveries related to the Crude Oil Pipeline Release as of December 31, 2015 . The estimated remediation costs of $66 million exceeded our policy loss limit by $41 million . We had remaining liabilities totaling $13 million and $27 million at September 30, 2016 and December 31, 2015 , respectively. LEGAL QUESTAR GAS COMPANY V. QEP FIELD SERVICES COMPANY. Prior to the acquisition of all of the limited liability company interests of QEPFS, QEPFS’ former affiliate, Questar Gas Company (“QGC”) and its affiliate Wexpro, filed a complaint on May 1, 2012 , asserting claims for breach of contract, breach of implied covenant of good faith and fair dealing, and an accounting and declaratory judgment related to a 1993 gathering agreement (the “1993 Agreement”) executed when the parties were affiliates. TLLP agreed to indemnify QEP Field Services Company for this claim under the acquisition agreement for QEPFS. Under the 1993 Agreement, certain of TLLP’s systems provide gathering services to QGC charging an annual gathering rate, which is based on the cost of service calculation. QGC disputed the annual calculation of the gathering rate, which has been calculated in the same manner since 1998, without objection by QGC. As a result of the rulings through the date of our acquisition of QEPFS, TLLP assumed a $21 million liability for estimated damages. On March 22, 2016 , the parties in this dispute entered into a settlement and release agreement resolving all remaining issues and associated counter claims in exchange for TLLP’s payment of $15 million . We recognized a gain of $6 million in other income, net on our condensed statement of consolidated operations for the nine months ended September 30, 2016 as a result of the settlement. XTO ENERGY INC. V. QEP FIELD SERVICES COMPANY. XTO filed a complaint on January 30, 2014 , asserting claims for breach of contract, breach of implied covenant of good faith and fair dealing, unjust enrichment and an accounting and declaratory judgment related to a 2010 gas processing agreement (the “XTO Agreement”). TLLP processes XTO’s natural gas on a firm basis under the XTO Agreement. The XTO Agreement requires TLLP to transport, fractionate and market XTO’s natural gas liquids derived from XTO’s processed gas. XTO is seeking monetary damages related to TLLP’s allocation of charges related to XTO’s share of natural gas liquid transportation, fractionation and marketing costs associated with shortfalls in contractual firm processing volumes. On March 29, 2016 , the parties entered into a settlement and release agreement related to payments withheld by XTO unrelated to the allocation of charges they are challenging. Under the settlement and release agreement, XTO agreed to pay all historical undisputed charges by April 15, 2016 less the allocated charges they are challenging, $29 million at September 30, 2016 , and to thereafter tender all similar undisputed charges timely. On April 15, 2016 , XTO remitted a $21 million settlement payment related to all undisputed amounts. While we cannot currently estimate the final amount or timing of the resolution of this matter and the disputed amounts, we believe the outcome will not have a material impact on our liquidity, financial position or results of operations.

Equity [Abstract]
Equity	EQUITY AND NET EARNINGS PER UNIT We had 68,901,930 common public units outstanding as of September 30, 2016 . Additionally, Tesoro owned 33,194,109 of our common units and 2,083,330 of our general partner units (the 2.0% general partner interest) as of September 30, 2016 , which together constitutes a 34% ownership interest. UNIT ISSUANCE. We closed a registered public offering of 6,325,000 common units representing limited partner interests, including the over-allotment option exercised by the underwriter for the purchase of an additional 825,000 common units, at a public offering price of $47.13 per unit on June 10, 2016 . The net proceeds of $293 million are expected to be used for general partnership purposes, which may include debt repayment, future acquisitions, capital expenditures and additions to working capital. ATM PROGRAM. On August 24, 2015 , we filed a prospectus supplement to our shelf registration statement filed with the SEC on August 6, 2015 , authorizing the continuous issuance of up to an aggregate of $750 million of common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of our offerings (such continuous offering program, or at-the-market program, referred to as our “ATM Program”). During the three and nine months ended September 30, 2016 , we issued an aggregate of 655,940 and 1,492,637 common units, respectively, under our ATM Program, generating proceeds of approximately $31 million and $72 million , respectively, before issuance costs. The net proceeds from sales under the ATM Program will be used for general partnership purposes, which may include debt repayment, future acquisitions, capital expenditures and additions to working capital. CHANGE IN THE CARRYING AMOUNT OF OUR EQUITY (in millions) Partnership Equity of Predecessors (a) Common General Partner Noncontrolling Interest Total Balance at December 31, 2015 $ 16 $ 1,707 $ (13 ) $ 84 $ 1,794 Sponsor contributions of equity to the Predecessors 34 — — — 34 Loss attributable to the Predecessors (4 ) — — — (4 ) Allocation of net assets acquired by the unitholders (b) (46 ) 40 6 — — Equity offering under ATM Program, net of issuance costs — 71 — — 71 Proceeds from issuance of units, net of issuance costs — 293 — — 293 Effect of deconsolidation of RGS (c) — (2 ) — (84 ) (86 ) Quarterly distributions to unitholders and general partner(d) — (234 ) (95 ) — (329 ) Distributions to unitholders and general partner related to acquisitions (b) — (321 ) (79 ) — (400 ) Net earnings attributable to partners — 154 109 — 263 Contributions (e) — 17 2 — 19 Other — 4 4 — 8 Balance at September 30, 2016 $ — $ 1,729 $ (66 ) $ — $ 1,663 (a) Adjusted to include the historical results of the Predecessors. See Note 1 for further discussion. (b) Distributions to unitholders and general partner include $400 million in cash payments for the Alaska Storage and Terminalling Assets acquisition from Tesoro. As an entity under common control with Tesoro, we record the assets that we acquire from Tesoro in our consolidated balance sheets at Tesoro’s historical book value instead of fair value, and any excess of cash paid over the historical book value of the assets acquired from Tesoro is recorded within equity. As a result of this accounting treatment, this transaction resulted in a net decrease of $354 million in our equity balance during the nine months ended September 30, 2016 . (c) As a result of the reassessment performed, we deconsolidated RGS causing the derecognition of noncontrolling interest and an opening equity impact totaling $86 million . The cumulative effect to opening equity of $2 million related to the difference in earnings under the equity method of accounting in prior periods. (d) Represents cash distributions declared and paid during the nine months ended September 30, 2016 relating to the fourth quarter of 2015 through the second quarter of 2016 . (e) Includes Tesoro and TLGP contributions to the Partnership primarily related to reimbursements for capital spending pursuant predominantly to the Amended Omnibus Agreement and the Carson Assets Indemnity Agreement. NET EARNINGS PER UNIT. We use the two-class method when calculating the net earnings per unit applicable to limited partners, because we have more than one participating security. At September 30, 2016 , our participating securities consist of common units, general partner units and IDRs. Net earnings earned by the Partnership are allocated between the common and general partners in accordance with our partnership agreement. We base our calculation of net earnings per unit on the weighted average number of common limited partner units outstanding during the period. Diluted net earnings per unit include the effects of potentially dilutive units on our common units, which consist of unvested service and performance phantom units. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement. NET EARNINGS PER UNIT (in millions, except per unit amounts) Three Months Ended Nine Months Ended 2016 2015 2016 2015 Net earnings $ 87 $ 71 $ 259 $ 206 Net earnings attributable to noncontrolling interest — (3 ) — (19 ) Special allocations of net earnings (“Special Allocations”) (a) 2 — 2 — Net earnings, excluding noncontrolling interest and including Special Allocations 89 68 261 187 General partner’s distributions (3 ) (1 ) (7 ) (4 ) General partner’s IDRs (b) (39 ) (19 ) (105 ) (47 ) Limited partners’ distributions on common units (89 ) (66 ) (250 ) (186 ) Distributions greater than earnings $ (42 ) $ (18 ) $ (101 ) $ (50 ) General partner’s earnings: Distributions $ 3 $ 1 $ 7 $ 4 General partner’s IDRs (b) 39 19 105 47 Allocation of distributions greater than earnings (c) (2 ) (6 ) (6 ) (17 ) Total general partner’s earnings $ 40 $ 14 $ 106 $ 34 Limited partners’ earnings on common units: Distributions $ 89 $ 66 $ 250 $ 186 Special Allocations (a) (2 ) — (2 ) — Allocation of distributions greater than earnings (40 ) (12 ) (95 ) (33 ) Total limited partners’ earnings on common units $ 47 $ 54 $ 153 $ 153 Weighted average limited partner units outstanding: Common units - basic 101.4 86.6 96.7 82.5 Common units - diluted 101.4 86.7 96.8 82.6 Net earnings per limited partner unit: Common - basic $ 0.46 $ 0.62 $ 1.58 $ 1.85 Common - diluted $ 0.46 $ 0.62 $ 1.58 $ 1.85 (a) Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions fully allocated to the general partner and any special allocations. The adjustment reflects the special allocation to common units held by TLGP for the interest incurred in connection with borrowings on the Dropdown Credit Facility in lieu of using cash on hand to fund the Alaska Storage and Terminalling Assets acquisition during the three and nine months ended September 30, 2016 . (b) IDRs entitle the general partner to receive increasing percentages, up to 50% , of quarterly distributions in excess of $0.3881 per unit per quarter. The amount above reflects earnings distributed to our general partner net of $3 million and $8 million of IDRs for the three and nine months ended September 30, 2015 , respectively, waived by TLGP. See Note 12 of our Annual Report on Form 10-K for the year ended December 31, 2015 , for further discussion related to IDRs. (c) We have revised the historical allocation of general partner earnings to include the Predecessors’ losses of $1 million and $4 million for the three and nine months ended September 30, 2016 , respectively, and $6 million and $17 million for the three and nine months ended September 30, 2015 , respectively. CASH DISTRIBUTIONS Our partnership agreement, as amended, sets forth the calculation to be used to determine the amount and priority of cash distributions that the limited partner unitholders and general partner will receive. The table below summarizes the quarterly distributions related to our quarterly financial results: QUARTERLY DISTRIBUTIONS Quarter Ended Quarterly Distribution Per Unit Total Cash Distribution including general partner IDRs (in millions) Date of Distribution Unitholders Record Date December 31, 2015 $ 0.780 $ 98 February 12, 2016 February 2, 2016 March 31, 2016 0.810 108 May 13, 2016 May 2, 2016 June 30, 2016 0.842 123 August 12, 2016 August 2, 2016 September 30, 2016 (a) 0.875 131 November 14, 2016 November 4, 2016 (a) This distribution was declared on October 18, 2016 and will be paid on the date of distribution.

The net proceeds of $293 million are expected to be used for general partnership purposes, which may include debt repayment, future acquisitions, capital expenditures and additions to working capital.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Segment Disclosures	OPERATING SEGMENTS Our revenues are derived from three operating segments: Gathering, Processing and Terminalling and Transportation. Our Gathering segment consists of crude oil and natural gas gathering systems in the Bakken Shale/Williston Basin area of North Dakota and Montana and the Green River Basin, Uinta Basin and Vermillion Basin in the states of Utah, Colorado and Wyoming. Our Processing segment consists of four gas processing complexes and one fractionation facility. Our Terminalling and Transportation segment consists of crude oil and refined products terminals and marine terminals, storage facilities for crude oil, refined products and petroleum coke handling, rail-car unloading facilities and pipelines, which transport products and crude oil. Our revenues are generated from third-party contracts and from commercial agreements we have entered into with Tesoro, under which customers pay us fees for gathering crude oil and natural gas, processing natural gas and distributing, transporting and storing crude oil, refined products, natural gas and natural gas liquids. The commercial agreements with Tesoro are described in greater detail in Note 3 to our Annual Report on Form 10-K for the year ended December 31, 2015 . We do not have any foreign operations. Our operating segments are strategic business units that offer different services in various geographical locations. We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses are excluded from segment operating income as they are not directly attributable to a specific operating segment.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of accounting, policy	We prepare our condensed combined consolidated financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the amounts of assets and liabilities and revenues and expenses reported as of and during the periods presented.
New accounting pronouncement, policy	NEW ACCOUNTING STANDARDS AND DISCLOSURES REVENUE RECOGNITION. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), and has since amended the standard with ASU 2015-14, “Deferral of the Effective Date,” ASU 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU 2016-10, “Identifying Performance Obligations and Licensing,” and ASU 2016-12, “Narrow-Scope Improvements and Practical Expedients.” These standards provide accounting guidance for all revenue arising from contracts to provide goods or services to customers. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2017. Early adoption as of January 1, 2017 is permitted; however, we do not intend to adopt early. The standard allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of the standard on our financial statements and related disclosures. Based on our initial evaluation, the adoption of the standard is not expected to have a material impact on the amount or timing of revenue recognized. CONSOLIDATION. In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis” (“ASU 2015-02”). This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for interim and annual periods beginning after December 15, 2015, and requires either a retrospective or a modified retrospective approach to adoption. We adopted this guidance using the modified retrospective approach as of January 1, 2016 and performed the required reassessments outlined by the guidance. For further information on the results of the reassessments, refer to Note 4, Investments - Equity Method and Joint Ventures. BUSINESS COMBINATIONS. In September 2015, the FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). The standard requires an acquirer to recognize the cumulative impact of adjustments to provisional purchase price amounts that are identified during the measurement period in the reporting period, in which the adjustment amounts are determined. The standard also requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for interim and annual periods beginning after December 15, 2015 and must be applied prospectively to adjustments that occur after the effective date. We adopted this guidance as of January 1, 2016, with no impact to our financial statements. LEASES. In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”), which improves transparency and comparability among organizations by requiring lessees to recognize a lease liability and a corresponding lease asset for virtually all lease contracts. It also requires additional disclosures about leasing arrangements. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and requires a modified retrospective approach to adoption. Early adoption is permitted. At this time, we are evaluating the potential impact of this standard on our financial statements. SHARE-BASED COMPENSATION. In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions including accounting for income taxes, cash flow presentation of tax impacts, forfeitures, and liability versus equity accounting due to statutory tax withholding requirements. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. As of January 1, 2016, we early adopted ASU 2016-09 and with respect to the guidance on forfeitures, we have elected to continue to estimate forfeitures on the date of grant to account for the estimated number of awards for which the requisite service period will not be rendered. The adoption of ASU 2016-09 had no impact on our financial statements. STATEMENT OF CASH FLOWS. In August 2016, the FASB issued ASU 2016-15, “Clarification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented, unless deemed impracticable, in which case, prospective application is permitted. At this time, we are evaluating the potential impact of this standard on our financial statements.

See Note 1 for further discussion. (b) Distributions to unitholders and general partner include $400 million in cash payments for the Alaska Storage and Terminalling Assets acquisition from Tesoro. As an entity under common control with Tesoro, we record the assets that we acquire from Tesoro in our consolidated balance sheets at Tesoro’s historical book value instead of fair value, and any excess of cash paid over the historical book value of the assets acquired from Tesoro is recorded within equity. As a result of this accounting treatment, this transaction resulted in a net decrease of $354 million in our equity balance during the nine months ended September 30, 2016 . (c) As a result of the reassessment performed, we deconsolidated RGS causing the derecognition of noncontrolling interest and an opening equity impact totaling $86 million . The cumulative effect to opening equity of $2 million related to the difference in earnings under the equity method of accounting in prior periods.

[3]	Distributions to unitholders and general partner include $400 million in cash payments for the Alaska Storage and Terminalling Assets acquisition from Tesoro. As an entity under common control with Tesoro, we record the assets that we acquire from Tesoro in our consolidated balance sheets at Tesoro’s historical book value instead of fair value, and any excess of cash paid over the historical book value of the assets acquired from Tesoro is recorded within equity. As a result of this accounting treatment, this transaction resulted in a net decrease of $354 million in our equity balance during the nine months ended September 30, 2016.
[4]	As a result of the reassessment performed, we deconsolidated RGS causing the derecognition of noncontrolling interest and an opening equity impact totaling $86 million. The cumulative effect to opening equity of $2 million related to the difference in earnings under the equity method of accounting in prior periods.
[5]	Represents cash distributions declared and paid during the nine months ended September 30, 2016 relating to the fourth quarter of 2015 through the second quarter of 2016.

[3]	Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions fully allocated to the general partner and any special allocations. The adjustment reflects the special allocation to common units held by TLGP for the interest incurred in connection with borrowings on the Dropdown Credit Facility in lieu of using cash on hand to fund the Alaska Storage and Terminalling Assets acquisition during the three and nine months ended September 30, 2016.
[4]	IDRs entitle the general partner to receive increasing percentages, up to 50%, of quarterly distributions in excess of $0.3881 per unit per quarter. The amount above reflects earnings distributed to our general partner net of $3 million and $8 million of IDRs for the three and nine months ended September 30, 2015, respectively, waived by TLGP. See Note 12 of our Annual Report on Form 10-K for the year ended December 31, 2015, for further discussion related to IDRs.
[5]	We have revised the historical allocation of general partner earnings to include the Predecessors’ losses of $1 million and $4 million for the three and nine months ended September 30, 2016, respectively, and $6 million and $17 million for the three and nine months ended September 30, 2015, respectively.
