Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Sunoco Logistics Partners L.P. (the "Partnership" or "SXL") is a publicly traded Delaware limited partnership that owns and operates a logistics business, consisting of a geographically diverse portfolio of integrated pipeline, terminalling, and acquisition and marketing assets which are used to facilitate the purchase and sale of crude oil, natural gas liquids ("NGLs") and refined products. The Partnership conducts its business activities in 37 states located throughout the United States. Sunoco Partners LLC, a Pennsylvania limited liability company and the general partner of the Partnership, is a consolidated subsidiary of Energy Transfer Partners, L.P. ("ETP"), a publicly traded Delaware limited partnership. On November 20, 2016, SXL and its general partner, Sunoco Partners LLC ("SXL GP"), a Pennsylvania limited liability company, entered into an Agreement and Plan of Merger (the "Merger Agreement") with ETP, together with Energy Transfer Partners GP, L.P. ("ETP GP"), a Delaware limited partnership and the general partner of ETP, and, solely for purposes of certain provisions therein, Energy Transfer Equity, L.P. ("ETE"), a Delaware limited partnership and indirect parent entity of ETP, ETP GP, the Partnership and SXL GP. Upon the terms and subject to the conditions set forth in the Merger Agreement, a wholly owned subsidiary of SXL will merge with ETP (the "Merger"), with ETP continuing as the surviving entity and a wholly-owned subsidiary of SXL. Concurrently with the Merger, SXL GP will merge with ETP GP, with ETP GP continuing as the surviving entity and becoming the general partner of SXL. Following the recommendation of the conflicts committee (the "ETP Conflicts Committee") of the board of directors of ETP's managing general partner (the "ETP Board"), the ETP Board approved and agreed to submit the Merger Agreement to a vote of ETP unitholders and to recommend that ETP's unitholders adopt the Merger Agreement. Following the recommendation of the conflicts committee of the board of directors of SXL GP, the board of directors of SXL GP approved the Merger Agreement. The Merger is expected to close in April 2017. Effective at the time of the Merger, all SXL units, 67.1 million common and 9.4 million Class B, currently held by ETP will be retired. The existing incentive distribution right ("IDR") provisions in the SXL Partnership Agreement will continue to be in effect, and ETE will own the IDRs of SXL following the closing of the transaction. As part of this transaction, ETE has agreed to continue to provide all the IDR subsidies that are currently in effect for both SXL and ETP. In addition, the 364-Day credit facility is expected to be terminated and repaid in connection with the Merger. At the effective time of the Merger, each common unit representing a limited partner interest in ETP issued and outstanding or deemed issued and outstanding as of immediately prior to the effective time of the merger will be converted into the right to receive 1.50 common units representing limited partner interests in SXL (the "SXL Common Units") (the "Merger Consideration"). Each Class E Unit of ETP, each Class G Unit of ETP, each Class I Unit of ETP, each Class J Unit of ETP and each Class K Unit of ETP, if any, issued and outstanding or deemed issued and outstanding as of immediately prior to the effective time of the Merger will be converted into the right to receive a corresponding unit in SXL with the same rights, preferences, privileges, powers, duties and obligations as such existing ETP unit had immediately prior to the Merger. The corresponding units in SXL will be issued pursuant to the Fourth Amended and Restated Partnership Agreement of Sunoco Logistics Partners L.P., which will be executed at the effective time.

Summary of Significant Accounti

Accounting Policies [Abstract]
Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements reflect the results of the Partnership and its wholly-owned subsidiaries, including Sunoco Logistics Partners Operations L.P. (the "Operating Partnership"), the proportionate shares of the Partnership's undivided interests in assets, and the accounts of entities in which the Partnership has a controlling financial interest. A controlling financial interest is evidenced by either a voting interest greater than 50 percent or a risk and rewards model that identifies the Partnership or one of its subsidiaries as the primary beneficiary of a variable interest entity. The Partnership currently holds a controlling financial interest in Inland Corporation ("Inland"), Mid-Valley Pipeline Company ("Mid-Valley"), Price River Terminal, LLC ("PRT"), and, effective February 1, 2017, Permian Express Partners LLC ("PEP"), which is a joint venture with ExxonMobil. These entities are reflected as consolidated subsidiaries of the Partnership. Effective November 1, 2016, SunVit Pipeline LLC ("SunVit") became a wholly-owned subsidiary of the Partnership in connection with the acquisition from Vitol Inc. The Partnership is not the primary beneficiary of any variable-interest entities ("VIEs"). All significant intercompany accounts and transactions are eliminated in consolidation and noncontrolling interests in net income and equity are shown separately in the consolidated statements of comprehensive income and balance sheets. Equity ownership interests in joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, are accounted for under the equity method of accounting. Use of Estimates The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates. Reclassification Certain amounts in the prior years' consolidated financial statements have been reclassified to conform to the current year presentation. The changes did not impact reported net income for any periods presented. New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, which created Topic 842, Leases, and will supersede the requirements in Topic 840. The objective of ASU 2016-02 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Partnership is currently evaluating the impact that it will have on its consolidated financial statements and related disclosures. In May 2014, the FASB codified guidance in ASU 2014-09 related to the recognition of revenue from contracts with customers, and has since released associated clarifying guidance in subsequent periods. The new standards outline the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods, with early adoption permitted. The Partnership expects to adopt ASU 2014-09 in the first quarter of 2018 and will apply the cumulative catchup transition method. The Partnership is in the process of evaluating its revenue contracts by segment and fee type to determine the potential impact of adopting the new standards. At this point in the evaluation process, it has been determined that the timing and/or amount of revenue recognized on certain contracts will be impacted by the adoption of the new standard; however, the process of quantifying these impacts is ongoing and an assessment of materiality in relation to the financial statements has not yet been determined. In addition, the Partnership is in the process of implementing appropriate changes to its business processes, systems and controls to support recognition and disclosure under the new standard. The Partnership will continue to monitor for additional authoritative or interpretive guidance related to the new standard as it becomes available, as well as comparing conclusions on specific interpretative issues to other peers in the industry, to the extent that such information is available. Revenue Recognition Pipeline revenues are recognized upon delivery of the barrels to the location designated by the shipper. Acquisition and marketing revenues for crude oil, NGLs and refined products are recognized when title to and risk of loss of the product is transferred to the customer. Terminalling and storage revenues are recognized at the time the services are provided. Revenues are not recognized for exchange transactions, which are entered into primarily to acquire a commodity of a desired quality or to reduce transportation costs by taking delivery closer to the Partnership's end markets. Any net differential for exchange transactions is recorded as an adjustment to cost of products sold in the consolidated statements of comprehensive income. Affiliated revenues are generated from sales of crude oil, NGLs and refined products, as well as pipeline transportation, terminalling and storage services to ETP and its affiliates. Sales of crude oil, NGLs and refined products to affiliated entities are priced using market-based rates. Affiliated entities pay fees for transportation or terminalling services based on the terms and conditions of established agreements or published tariffs. Cash Equivalents The Partnership considers all highly liquid investments with a remaining maturity of three months or less at the time of purchase to be cash equivalents. At December 31, 2016 and 2015, cash equivalents consisted of time deposits and money market investments. Accounts Receivable, Net Accounts receivable represent valid claims against non-affiliated customers (see Note 4 for affiliated receivables) for products sold or services rendered. The Partnership extends credit terms to certain customers after review of various credit indicators, including the customers' credit ratings. Outstanding customer receivable balances are regularly reviewed for possible non-payment indicators and reserves are recorded for doubtful accounts based upon management's expectations regarding collectability. Actual receivable balances are charged against the reserve when all collection efforts have been exhausted. Inventories Inventories are valued at the lower of cost or market. Crude oil, NGLs and refined products inventory costs have been determined using the last-in, first-out method ("LIFO"). Under this methodology, the cost of products sold consists of the actual acquisition costs of the Partnership, which include transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities, which are valued based on the changes in the LIFO inventory layers. The cost of materials, supplies and other inventories is principally determined using the average-cost method. During the periods ended December 31, 2016, 2015 and 2014, a lower of cost or market ("LCM") adjustment was applied, as necessary, to the Partnership's crude oil, NGLs and refined products inventories due to changes in commodity prices. Adjustments are calculated based upon current replacement costs. See Notes 6 and 18 for additional information on the LCM reserves and their impact to the Partnership's net income. Properties, Plants and Equipment Properties, plants and equipment are stated at cost. Additions to properties, plants and equipment, including replacements and improvements, are recorded at cost. Repair and maintenance expenditures are charged to expense as incurred. Depreciation is determined principally using the straight-line method based on the estimated useful lives of the related assets. For certain interstate pipelines, the depreciation rate is applied to the net asset value based on the Federal Energy Regulatory Commission's ("FERC") requirements, which approximates the estimated useful lives of the related assets. Capitalized Interest The Partnership capitalizes interest incurred on funds borrowed for certain capital projects and contributions to joint venture interests during periods in which construction activities are in progress to bring those projects to their intended use. Investment in Affiliates Investment in affiliates, which consist of joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, are accounted for under the equity method of accounting. Under this method, an investment is carried at cost, adjusted for the equity in income (loss), reduced for dividends received and adjusted for changes in accumulated other comprehensive income (loss). Income recognized from the Partnership's joint venture interests is presented within other income in the consolidated statements of comprehensive income. The Partnership allocates the excess of its investment cost over its equity in the net assets of affiliates to the underlying tangible and intangible assets of the joint ventures. Other than land and indefinite-lived intangible assets, all amounts allocated, principally to pipeline and related assets, are amortized using the straight-line method over their estimated useful life of 40 years . The amortization of these amounts is also presented within other income in the consolidated statements of comprehensive income. Acquisitions The Partnership records third-party business combinations at their estimated fair values as of the date of acquisition. Any excess of consideration transferred plus the fair value of noncontrolling interest over the estimated fair value of the net assets acquired is recorded as goodwill. To the extent the estimated fair value of the net assets acquired exceeds the purchase price plus the fair value of the noncontrolling interest, a gain is recorded in results of current operations. The results of operations of acquired businesses are included in the Partnership's results from the dates of acquisition. Assets acquired and liabilities assumed include tangible and intangible assets, and contingent assets and liabilities. The estimated fair values of these assets and liabilities are determined based on observable inputs such as quoted market prices, information from comparable transactions, offers made by other prospective acquirers in the cases where the Partnership has certain rights to acquire additional interests in existing investments, and the replacement cost of assets in the same condition or stage of usefulness; or on unobservable inputs such as expected future cash flows or internally developed estimates of value. The Partnership's fair value measurements are classified within the fair value hierarchy established by GAAP based on the lowest level (least observable) input that is significant to the measurement in its entirety. Assets acquired and liabilities assumed in connection with acquisitions from entities under common control are recorded by the Partnership at the common control entity's net carrying value. The Partnership records any difference between the consideration paid and the carrying value of the net assets and liabilities as a distribution from, or contribution to, redeemable limited partner interests or equity, as applicable. The Partnership's asset acquisitions are recorded at the purchase price, which is allocated to the acquired assets and assumed liabilities based on their relative estimated fair values. See Note 3 for additional information concerning the Partnership's recent acquisitions. Impairment of Long-Lived Assets Long-lived assets, other than those held for sale, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An asset is considered to be impaired when the undiscounted estimated net cash flows expected to be generated by the asset are less than its carrying amount. The impairment recognized is the amount by which the carrying amount exceeds the estimated fair value of the impaired asset. Long-lived assets held for sale are recorded at the lower of their carrying amount or estimated fair value less cost to sell the assets. Goodwill Goodwill, which represents the excess of the purchase price in a business combination over the fair value of net assets acquired, is tested for impairment annually in the fourth quarter, or more often if events or changes in circumstances indicate that the carrying value of goodwill may exceed its estimated fair value. The Partnership's general partner was acquired and became a consolidated subsidiary of ETP in the fourth quarter 2012. In connection with the acquisition, the Partnership elected to apply "push-down accounting" which required the Partnership's assets and liabilities to be adjusted to fair value on the closing date of the acquisition, which included an increase to the Partnership's goodwill balance of approximately $ 1.3 billion. Management's process for evaluating goodwill for impairment involves estimating the fair value of the Partnership's reporting units that include goodwill. Inherent in estimating fair value for each reporting unit are certain judgments and estimates relating the market multiples for comparable businesses, management's interpretation of current economic indicators, and market conditions and assumptions about the Partnership's strategic plans with regards to its operations. To the extent additional information arises, market conditions change or the Partnership's strategies change, it is possible the conclusion regarding whether the goodwill is impaired could change and result in future goodwill impairment charges. During the fourth quarter 2015, the Partnership realigned its reporting segments and, in accordance with accounting guidance, was required to test its goodwill balance for impairment both before and after the change in its reportable segments. Due to volatility within the energy markets, the Partnership utilized the assistance of a third party valuation firm to develop models to estimate the fair value of each of its reporting units that contain goodwill. The fair value of the reporting units was estimated using a combination of discounted cash flow and market multiple methodologies. Under the discounted cash flow methodology, fair value was estimated using the present value of Management's projected cash flows for each reporting unit which was calculated using the expected return a market participant would require for each reporting unit. Under the market multiple methodology, a selection of peer group companies, which are similar from an operational or industry perspective, were considered in estimating market multiples. These multiples were applied to Management's projected Adjusted EBITDA in order to estimate fair value. For the 2015 impairment test, the fair value of the Partnership's legacy Crude Oil Acquisition and Marketing segment was determined to be approximately 3 percent less than its carrying value. In accordance with accounting guidance, a second test was performed to estimate the fair value of the reporting unit's assets and liabilities, which included determining an implied goodwill value. The Partnership performed the second test and determined that the implied fair value of the Crude Oil Acquisition and Marketing segment's goodwill exceeded its current carrying value. See Note 9 for additional information on the Partnership's goodwill balance. Intangible Assets The Partnership has acquired intangible assets, such as customer relationships and patents related to butane blending technology. The value assigned to these intangible assets is amortized on a straight-line basis over their respective economic lives through depreciation and amortization expense in the consolidated statements of comprehensive income. Environmental Remediation The Partnership accrues environmental remediation costs for work at identified sites where an assessment has indicated that cleanup costs are probable and reasonably estimable. Such accruals are undiscounted and are based on currently available information, estimated timing of remedial actions and related inflation assumptions, existing technology and presently enacted laws and regulations. If a range of probable environmental cleanup costs exists for an identified site, the minimum of the range is accrued unless some other point or points in the range are more likely, in which case the most likely amount in this range is accrued. Income Taxes The Partnership is not a taxable entity for U.S. federal income tax purposes, or for the majority of states that impose income taxes. Rather, income taxes are generally assessed at the partner level. There are some states in which the Partnership operates where it is subject to state and local income taxes. Substantially all of the income tax amounts reflected in the Partnership's consolidated financial statements are related to the operations of Inland, Mid-Valley and West Texas Gulf Pipe Line Company ("West Texas Gulf"), all of which are subject to income taxes for federal and state purposes at the corporate level. The effective tax rates for these entities approximate the federal statutory rate of 35 percent . The Partnership recognizes a tax benefit from uncertain positions only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authorities' widely understood administrative practices and precedents. The tax benefits recognized from such positions are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement. The following table presents the components of income tax expense for the periods presented: Year Ended December 31, 2016 2015 2014 (in millions) Federal Current $ 22 $ 15 $ 24 Deferred 2 6 (5 ) State Current 4 — 6 Deferred (1 ) — — Total income tax expense $ 27 $ 21 $ 25 The income taxes paid by Inland, Mid-Valley, and West Texas Gulf approximated current income tax expense for each year presented. In taxable jurisdictions, the Partnership records deferred income taxes on all significant temporary differences between the book basis and the tax basis of assets and liabilities. At December 31, 2016 and 2015, the Partnership had $ 257 and $ 254 million, respectively, of net deferred tax liability derived principally from the difference in the book and tax bases of properties, plants and equipment associated with Inland, Mid-Valley, and West Texas Gulf. Long-Term Incentive Plan The Partnership accounts for the compensation cost associated with all unit-based payment awards at grant-date fair value and reports the related expense within operating expenses and selling, general and administrative expenses in the consolidated statements of comprehensive income. Unit-based compensation cost for all outstanding awards of restricted units is based on the grant date market price of the underlying unit. The Partnership recognizes unit-based compensation expense on a straight-line basis over the requisite service period. In accordance with the terms of certain awards, the recognition of compensation expense is accelerated for participants who become retirement-eligible during the applicable vesting period. Asset Retirement Obligations Asset retirement obligations ("AROs") represent the fair value of expected liabilities related to the future retirement of long-lived assets and are recorded at the time in which a legal obligation is incurred. A corresponding asset is recorded concurrently and is depreciated over the anticipated active life of the related long-lived asset. The value of the ARO is determined based on estimates and assumptions regarding ongoing maintenance and repair, asset repurposing costs, disposal costs and associated contractual obligations related to the Partnership's pipelines, terminal facilities, storage tanks, truck and leased assets. The Partnership bases these estimates on historical and budgeted costs, future inflation rates and credit-adjusted risk-free interest rates. These fair value assessments are considered to be level 3 measurements, as they are based on both observable and unobservable inputs. The Partnership's consolidated balance sheets include AROs as a component of other deferred credits and liabilities of $ 88 million at December 31, 2016 and 2015. The Partnership believes it may have additional asset retirement obligations related to its pipeline assets and storage tanks for which it is not possible to estimate whether or when the retirement obligations will be settled. Consequently, these retirement obligations cannot be measured at this time. Fair Value Measurements The Partnership determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy established by the FASB. Where quoted pricing is not available, the Partnership utilizes a "market" or "income" approach to determine fair value. This method uses pricing and other information related to market transactions for identical or comparable assets and liabilities. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety. Lease Accounting The Partnership accounts for arrangements that convey the right to use property, plant or equipment for a stated period of time as leases. Whether an arrangement contains a lease is determined at inception of the arrangement based on all of the facts and circumstances. The Partnership reassesses whether an arrangement contains a lease after the inception of the arrangement only if (a) there is a change in the contractual terms, (b) a renewal option is exercised or an extension is agreed to by the parties to the arrangement, (c) there is a change in the determination of whether or not fulfillment is dependent on specified property, plant, or equipment, or (d) there is a substantial physical change to the specified property, plant, or equipment. The Partnership continually analyzes its new and existing arrangements to evaluate whether they contain leases. Revenue or expense from arrangements where the Partnership is the lessor or lessee, respectively, is recognized ratably over the term of the underlying arrangement. Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit The Partnership uses the two-class method to determine basic and diluted earnings per unit. The two-class method is an earnings allocation formula that determines the earnings for each class of equity ownership and participating security according to distributions declared and participation rights in undistributed earnings. The Partnership calculates basic and diluted net income attributable to Sunoco Logistics Partners L.P. ("net income attributable to SXL") per limited partner unit by dividing net income attributable to SXL, after deducting the amounts allocated to the general partner's interest and incentive distribution rights ("IDRs"), by the weighted average number of limited partner units and Class B units outstanding during the period. IDRs in a master limited partnership are treated as participating securities for the purpose of computing net income attributable to limited partner units. The general partner holds all of the IDRs. In addition, when earnings differ from cash distributions, undistributed or over distributed earnings are to be allocated to the general partner, limited partners and Class B unitholders based on the contractual terms of the partnership agreement. See Note 4 for additional information on the terms of the Class B units.

Business Combinations [Abstract]
Acquisitions	Acquisitions A key component of the Partnership's primary business strategy is to pursue strategic and accretive acquisitions that complement its existing asset base. The Partnership completed the following acquisitions during the years ended December 31, 2016, 2015 and 2014: • In November 2016, the Partnership completed an acquisition from Vitol Inc. ("Vitol") of an integrated crude oil business in West Texas for $ 760 million plus working capital. The acquisition provides the Partnership with an approximately 2 million barrel crude oil terminal in Midland, Texas, a crude oil gathering and mainline pipeline system in the Midland Basin, including a significant acreage dedication from an investment-grade Permian producer, and crude oil inventories related to Vitol crude oil purchasing and marketing business in West Texas. The acquisition also included the purchase of a 50 percent interest in the SunVit Pipeline LLC ("SunVit"), which resulted in the entity becoming a wholly-owned subsidiary of the Partnership. SunVit, which was renamed Permian Express Terminal LLC ("PET") in the fourth quarter 2016, connects the Midland terminal to the Partnership's Permian Express 2 pipeline, a key takeaway to bring Permian crude oil to multiple markets. The acquisition is included in the Crude Oil segment. The $ 769 million purchase price, net of cash received, consisted primarily of the following preliminary fair value allocations: net working capital ($ 13 million) largely attributable to inventory and receivables; properties, plants and equipment ($ 286 million) primarily related to pipeline and terminalling assets; intangible assets ($ 313 million) attributable to customer relationships; and an increase to goodwill ($ 251 million). The consolidation of SunVit resulted in a $ 41 million gain which represented the difference between the carrying value of the Partnership's previously held equity interest and the fair value on the date of acquisition. • In August 2016 and March 2014, the Partnership acquired additional ownership interests in the Explorer Pipeline Company ("Explorer") for $ 17 and $ 42 million, respectively, which increased the total ownership interest from 9.4 to 15.0 percent. The equity-method investment continues to be reported within the Refined Products segment. • In December 2014, the Partnership acquired an additional 28.3 percent ownership interest in West Texas Gulf from Chevron Pipe Line Company for $ 325 million, increasing the Partnership's controlling financial interest to 88.6 percent. In January 2015, the Partnership acquired the remaining noncontrolling ownership interest in West Texas Gulf for $ 131 million. As these transactions represented the acquisition of ownership interest in a consolidated subsidiary, noncontrolling interest and partners' equity were reduced by $ 92 and $ 364 million, respectively, in accordance with applicable accounting guidance. West Texas Gulf is reflected as a consolidated subsidiary within the Crude Oil segment. • In the second quarter 2014, the Partnership acquired a crude oil purchasing and marketing business from EDF Trading North America, LLC ("EDF"). The purchase consisted of a crude oil acquisition and marketing business and related assets which handle 20 thousand barrels per day. The acquisition also included a promissory note that was convertible to an equity interest in a rail facility (see below). The acquisition is included in the Crude Oil segment. • In the second quarter 2014, the Partnership acquired a 55 percent economic and voting interest in PRT, a rail facility in Wellington, Utah. As the Partnership acquired a controlling financial interest in PRT, the entity is reflected as a consolidated subsidiary of the Partnership from the acquisition date and is included in the Crude Oil segment. The terms of the acquisition provide PRT's noncontrolling interest holders the option to sell their interests to the Partnership at a price defined in the purchase agreement. As a result, the noncontrolling interests attributable to PRT are excluded from the Partnership's total equity and are instead reflected as redeemable interests in the consolidated balance sheet. The $ 65 million purchase price for the EDF and PRT acquisitions (net of cash received) consisted primarily of net working capital largely attributable to inventory ($ 24 million), properties, plants and equipment ($ 14 million), and intangible assets ($ 28 million). These fair value allocations also resulted in an increase to goodwill ($ 12 million) and redeemable noncontrolling interests ($ 15 million). No pro forma information has been presented as the impact of the acquisitions during 2016, 2015 and 2014 was not material in relation to the Partnership's consolidated results of operations or financial position.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Acquisition of Sunoco The Partnership has various operating and administrative agreements with ETP and its affiliates, including the agreements described below. ETP and its affiliates perform the administrative functions defined in such agreements on the Partnership's behalf. Service and Commodity Sales Agreements The Partnership is party to various agreements with ETP and its affiliates to provide pipeline, terminalling and storage services, in addition to agreements for the purchase and sale of crude oil, NGLs and refined products. This activity is reflected in affiliated revenues in the consolidated statements of comprehensive income. The Partnership is party to the following commercial agreements with its affiliated entities: • Pipeline Operator Agreement: The Partnership has agreements with certain of its joint venture interests to serve as operators of their respective pipeline systems. The agreements include a specified management fee and have either a defined termination date or are able to be terminated by both parties in certain cases. • Refined Products Terminal Services Agreement: The Partnership has a five -year refined products terminal services agreement with Sunoco under which Sunoco may throughput refined products at the Partnership's terminals. The agreement contains no minimum throughput obligations for Sunoco. The agreement runs through February 2017. • Fort Mifflin Terminal Services Agreement: The Partnership has an agreement with Philadelphia Energy Solutions ("PES") relating to the Fort Mifflin terminal complex. Under this agreement, PES will deliver an average of 300 thousand barrels per day of crude oil and refined products per contract year at the Fort Mifflin facility. PES does not have exclusive use of the Fort Mifflin terminal complex; however, the Partnership is obligated to provide the necessary tanks, marine docks and pipelines for PES to meet its minimum requirements under the agreement. The Partnership executed the ten -year agreement with PES in September 2012. The Partnership had a previous agreement with Sunoco, with terms similar to those contained in the agreement with PES. These agreements also provide PES with the option to purchase the Fort Mifflin and Belmont terminals if certain triggering events occur, including a sale of substantially all of the assets or operations of the Philadelphia refinery, an initial public offering, or a public debt filing of more than $ 200 million. The purchase price for each facility would be established based on a fair value amount determined by designated third parties. • Inter-Refinery Pipeline Lease: In September 2012, Sunoco assigned its lease for the use of the Partnership's inter-refinery pipelines between the Philadelphia refinery and the Marcus Hook Industrial Complex to PES. Under the twenty-year lease agreement which expires in February 2022, PES leases the inter-refinery pipelines for an annual fee which escalates at 1.67 percent each January 1 for the term of the agreement. The lease agreement also requires PES to reimburse the Partnership for any non-routine maintenance expenditures, as defined, incurred during the term of the agreement. There were no material reimbursements under this agreement during the years 2014 through 2016. • Marcus Hook Industrial Complex Storage and Terminalling Services: In connection with the 2013 acquisition of the Marcus Hook Industrial Complex, the Partnership assumed an agreement to provide butane storage and terminal services to PES at the facility. The 10 year agreement extends through September 2022. • Refined Products Storage Agreements: The Partnership has agreements with an affiliated entity to utilize storage services at the Mont Belvieu, Texas and Hattiesburg, Mississippi terminal locations. The agreements run through November 2018. • Purchase and Sale Agreements: The Partnership has agreements for the purchase and sale of crude oil, NGLs and refined products with affiliated entities. These agreements are negotiated at market-based rates, do not extend beyond 2017, and can be terminated by either party in certain cases. • Terminalling Services: The Partnership has agreements with affiliates for the use of its terminal assets, as well as its use of an affiliated terminal asset to facilitate the Partnership's acquisition and marketing activities. The agreements are based on market terms and negotiated based on the respective term. These agreements vary in duration and can be terminated by either party in certain cases. • Pipeline Agreements: The Partnership has agreements with affiliated parties to utilize its pipelines to supply their business needs. All pipeline movements are on the same terms that would be available to unaffiliated customers under similar terms and are based on published tariff rates on the respective pipeline. Advances to/from Affiliate The Partnership previously participated in Sunoco's centralized cash management program pursuant to a treasury services agreement. Under the program, the Partnership's cash receipts and cash disbursements were processed, together with those of Sunoco and its other subsidiaries, through Sunoco's cash accounts with a corresponding credit or charge to an affiliated account. The Partnership established separate cash accounts in the fourth quarter 2013, and ceased participation in Sunoco's cash management program in 2014. Administrative Services The Partnership has no employees. The operations of the Partnership are carried out by employees of the general partner. The Partnership reimburses the general partner and its affiliates for certain costs and other direct expenses incurred on the Partnership's behalf. These costs may be increased if the acquisition or construction of new assets or businesses requires an increase in the level of services received by the Partnership. Additional general and administrative costs incurred are paid directly by the Partnership. Under the Omnibus Agreement, the Partnership pays ETP an annual administrative fee that includes expenses incurred by ETP and its affiliates to perform certain centralized corporate functions, such as legal, accounting, engineering, information technology, insurance, utilities expense, office space rental, and other corporate services, including the administration of employee benefit plans. The costs may be increased if the acquisition or construction of new assets or businesses requires an increase in the level of general and administrative services received by the Partnership. These fees do not include the costs of shared insurance programs (which are allocated to the Partnership based upon its share of the cash premiums incurred), the salaries of pipeline and terminal personnel or other employees of the general partner, or the cost of their employee benefits. The amounts incurred in connection with the centralized corporate functions and shared insurance costs were not material to the Partnership's results of operations during the three year period ended December 31, 2016. The Partnership participates in various employee benefit plans with ETP and its affiliates, including employee and retiree medical, dental and life insurance plans, defined contribution 401(k) plans, incentive compensation plans and other such benefits. The total expense of benefit plan participation was $ 61 , $ 54 , and $45 million for the years ended December 31, 2016, 2015 and 2014, respectively. These expenses are reflected in operating expenses and selling, general and administrative expenses in the consolidated statements of comprehensive income. Affiliated Revenues and Accounts Receivable, Affiliated Companies The Partnership is party to various agreements with ETP and its affiliates to supply crude oil, NGLs and refined products, as well as to provide pipeline and terminalling services. Affiliated revenues in the consolidated statements of comprehensive income consist of revenues from ETP and its affiliated entities related to sales of crude oil, NGLs and refined products, and services, including pipeline transportation, terminalling, storage and blending. Note Receivable, Affiliated Companies See Note 8 for additional information related to the note receivable in connection with the Bakken Pipeline project. Investments in Affiliates See Note 8 for additional information related to the Partnership's participation in the Bayou Bridge and Bakken pipeline projects. Issuance of Redeemable Limited Partners' Interests In October 2015, the Partnership issued 9.4 million Class B units to ETP in conjunction with the purchase of a 30 percent ownership interest in the Bakken pipeline. The Class B units represent a new class of limited partner interests in the Partnership which are not entitled to receive quarterly distributions that are made on the Partnership's common units, but are otherwise entitled to share in earnings pro-rata with common units. The Class B units will automatically convert to common units on a one-for-one basis in the third quarter 2017. ETP can exercise a put right during the third quarter 2017, effective prior to the one-for-one conversion date, for the greater of $ 313.5 million or the fair market value of the units, as defined in the unitholder agreement. As a result of the available put option, the amount attributable to the Class B units is excluded from total equity and instead reflected as redeemable interests in the Partnership's consolidated balance sheet. However, the Class B units will be retired without exercise if the Merger is approved (see Note 1 for additional information). Contributions Attributable to Acquisition from Affiliate In the fourth quarter 2014, the Partnership acquired land at Eagle Point from Sunoco under a purchase option embedded in an existing lease. As a transaction between entities under common control, the land was recorded at Sunoco's historical carrying value, resulting in an increase to equity of $ 54 million. Capital Contributions In July 2014, the Partnership agreement was amended to remove the obligation of the general partner to make capital contributions upon the issuance of limited partner units to retain a two percent interest. Prior to this amendment, the general partner contributed $ 2 million primarily related to the Partnership's issuance of limited partner units under its at-the-market equity offering program ("ATM" program) in 2014. The general partner did not make any capital contributions to the Partnership in 2015 or 2016.

Earnings Per Share [Abstract]
Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit	Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit The general partner's interest in net income attributable to SXL consists of its general partner interest and "incentive distributions," which are increasing percentages, up to 50 percent of quarterly distributions in excess of $0.0833 per limited partner unit (Note 13). The general partner was allocated net income attributable to SXL of $ 393 million (representing 56 percent of total net income attributable to SXL) for the year ended December 31, 2016; $ 288 million (representing 73 percent of total net income attributable to SXL) for the year ended December 31, 2015; $181 million (representing 62 percent of total net income attributable to SXL) for the year ended December 31, 2014. Diluted net income attributable to SXL per limited partner unit is calculated by dividing the limited partners' interest in net income attributable to SXL by the sum of the weighted average number of limited partner and Class B units outstanding, and the dilutive effect of incentive unit awards (Note 14). For the year ended December 31, 2016, net income attributable to SXL was reduced by $ 14 million in determining earnings per limited partner unit as a result of the Class B units, which are reflected as redeemable limited partner interests in the consolidated balance sheet. The following table sets forth the reconciliation of the weighted average number of limited partner and Class B units used to compute basic net income attributable to SXL per limited partner unit to those used to compute diluted net income attributable to SXL per limited partner unit for the periods presented: Year Ended December 31, 2016 2015 2014 (in millions) Weighted average number of units outstanding—basic 304.5 250.9 212.9 Add effect of dilutive incentive awards 0.9 0.8 1.2 Weighted average number of units—diluted 305.4 251.7 214.1

(2) The investment in Bakken HoldCo provides the Partnership with a 30 percent overall ownership interest in the Bakken pipeline project through its ownership in the subsidiary companies which will operate the pipeline system. Explorer Pipeline Company In the third quarter 2016, the Partnership purchased an additional 1.7 percent ownership interest in Explorer from EXPL Pipeline Investment LLC for $ 17 million, increasing the Partnership's ownership interest to 15.0 percent . Explorer owns a refined products pipeline running from the Gulf Coast of the United States to the Chicago, Illinois area. The investment continues to be accounted for as an equity method investment within the Partnership's Refined Products segment. Permian Express Terminal In November 2016, the Partnership acquired an additional 50 percent interest in SunVit from Vitol, which increased the Partnership's overall ownership of SunVit to 100 percent . In December 2016, the Partnership renamed the SunVit pipeline to Permian Express Terminal LLC ("PET"). See Note 3 for additional information on the acquisition from Vitol. Bayou Bridge Pipeline In July 2015, the Partnership entered into an agreement with ETP and Phillips 66 to participate in the Bayou Bridge Pipeline project. The Partnership obtained a 30 percent economic interest in the project which is a consolidated subsidiary of ETP. The project consists of a newly constructed pipeline that will deliver crude oil from Nederland, Texas to refinery markets in Louisiana. Commercial operations from Nederland, Texas to Lake Charles, Louisiana commenced in the second quarter 2016, with continued progress on an extension of the pipeline segment to St. James, Louisiana, which is expected commence operations in the fourth quarter 2017. The Partnership is the operator of the pipeline and continues to fund its proportionate share of the cost of the project, which is accounted for as an equity method investment within the Partnership's Crude Oil segment. Bakken Pipeline In October 2015, the Partnership finalized its participation in the Bakken pipeline project with ETP and Phillips 66. The Partnership obtained a 30 percent economic interest in the project which is a consolidated subsidiary of ETP. The project consists of existing and newly constructed pipelines that are expected to provide aggregate takeaway capacity of approximately 450 thousand barrels per day of crude oil from the Bakken/Three Forks production area in North Dakota to key refinery and terminalling hubs in the midwest and Gulf Coast, including the Partnership's Nederland terminal. The ultimate takeaway capacity target for the project is 570 thousand barrels per day. The Partnership expects to reach agreement to become the operator of the pipeline system, which is expected to begin commercial operations in the second quarter 2017. In exchange for its 30 percent economic interest in the project, the Partnership issued 9.4 million Class B units to ETP, representing limited partner interests in the Partnership, and paid $ 382 million in cash representing the Partnership's proportionate share of contributions at the time of closing. Since the interest in the project was acquired from a related party, the Partnership's investment was recorded at ETP's historical carrying value. The Partnership's investment in the Bakken Pipeline project is reflected as an equity method investment within the Crude Oil segment. See Note 4 for additional information on the issuance of the Class B units. In August 2016, ETP, Sunoco Logistics and Phillips 66 established a $ 2.5 billion credit facility to provide substantially all of the remaining capital necessary to complete the project. Borrowings under the credit facility are secured by all assets of the Bakken entities, as well as the ownership interests maintained by the joint partners. The facility was limited to $ 1.1 billion in borrowings until attainment of certain closing conditions, which were met in February 2017. At December 31, 2016, $ 1.1 billion was outstanding under the Bakken credit facility. The joint partners agreed to provide the Bakken entities with a short-term loan until the full capacity of the $ 2.5 billion credit facility was available. The loan was made by the partners in proportion to their respective ownership interests. The outstanding balance of the note receivable due to the Partnership by the Bakken entities at December 31, 2016 was $ 301 million and was repaid in February 2017. In February 2017, the Partnership and ETP completed the sale of 49 percent of their respective interests in the Bakken Pipeline project for $ 2.0 billion to MarEn Bakken Company LLC, an entity jointly owned by MPLX LP and Enbridge Energy Partners, L.P. The Partnership received $ 800 million for its interest. The carrying amount of the Partnership's investment in the Bakken Pipeline project was $ 639 million at December 31, 2016. As a result of the sale, the Partnership's ownership interest in the Bakken Pipeline project is 15.3 percent . At December 31, 2016, the Partnership's investments in Explorer Pipeline Company, Yellowstone Pipe Line Company, West Shore Pipe Line Company and Wolverine Pipe Line Company included net excess investment amounts of $ 135 million. The excess investment is the difference between the investment balances and the Partnership's equity in the net assets of the entities. The Partnership has not provided additional financial support to any of these joint ventures during the 2014 through 2016 periods. The Partnership had $ 63 million of undistributed earnings from its investments in joint ventures within equity at December 31, 2016. During the years ended December 31, 2016, 2015 and 2014, the Partnership recorded equity income of $ 39 , $ 24 , and $ 25 million, respectively, and received dividends of $ 25 , $ 23 , and $ 14 million, respectively, from its investments in joint ventures.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill Goodwill, which represents the excess of the purchase price in a business combination over the fair value of net assets acquired, is tested for impairment annually in the fourth quarter, or more often if events or changes in circumstances indicate that the carrying value of goodwill may exceed its estimated fair value. The Partnership's goodwill balance at December 31, 2016 and 2015 was $ 1,609 and $1,358 million, respectively. The $ 251 million increase in the Partnership's goodwill balance resulted from the Partnership's November 2016 acquisition from Vitol (Note 3). There were no goodwill impairments recorded during the 2014 through 2016 period. In connection with the change in the Partnership's reporting segments in the fourth quarter 2015, goodwill was reassigned to the new reporting segments. The Partnership's legacy Crude Oil Pipelines, Crude Oil Acquisition and Marketing, and Terminal Facilities segments included goodwill of $ 200 , $ 557 , and $ 601 million, respectively. The goodwill related to the legacy Crude Oil Pipelines and Crude Oil Acquisition and Marketing segments was combined under the Partnership's new segment alignment, while the goodwill related to the legacy Terminal Facilities segment was allocated to the new segments based on a relative fair value basis. Subsequent to the realignment of its reporting segments, the Partnership's Crude Oil, Natural Gas Liquids, and Refined Products segments include goodwill of $ 912 , $ 357 , and $ 89 million, respectively, at December 31, 2015. The Partnership will continue to monitor the volatility in the energy markets and the impact it could have on the estimated fair value of its reporting segments. It is possible that continued negative volatility within these markets could change the Partnership's conclusion regarding whether goodwill is impaired. Identifiable Intangible Assets The Partnership's identifiable intangible assets are comprised of customer relationships and patented technology associated with the Partnership's butane blending services. The values assigned to these intangible assets are amortized to earnings using a straight-line approach, over a weighted average amortization period of approximately 17 years . Amortization expense related to these intangibles was $ 54 , $52 , and $52 million for the years ended December 31, 2016, 2015 and 2014, respectively. The $ 313 million increase in the Partnership's intangible assets is attributable to customer relationships acquired in connection with its acquisition from Vitol (Note 3). Customer relationship intangible assets represent the estimated economic value assigned to certain relationships acquired in connection with business combinations or asset purchases whereby (i) the Partnership acquired information about or access to customers, (ii) the customers now have the ability to transact business with the Partnership and (iii) the Partnership is positioned, due to limited competition, to provide products or services to the customers. The customer relationship intangible assets are amortized on a straight-line basis over their respective economic lives. Technology-related intangible assets consist of the Partnership's patents for blending of butane into refined products. These patents are amortized over their remaining legal lives. Weighted Average Amortization Period December 31, 2016 2015 (in years) (in millions) Gross Customer relationships 18 $ 1,149 $ 836 Technology 10 47 47 Total gross 1,196 883 Accumulated amortization Customer relationships (199 ) (149 ) Technology (20 ) (16 ) Total accumulated amortization (219 ) (165 ) Total Net $ 977 $ 718 The Partnership forecasts $ 69 million of annual amortization expense for each year through the year 2021 for its intangible assets. Intangible assets attributable to rights-of-way are included in properties, plants and equipment in the Partnership's consolidated balance sheets at December 31, 2016 and 2015 (Note 7).

There was no commercial paper outstanding at December 31, 2015. (2) The $1.0 billion 364-Day Credit Facility, including its $630 million term loan, is classified as long-term debt at December 31, 2016 as the Partnership has the ability and intent to refinance such borrowings on a long-term basis. (3) The 6.125 percent Senior Notes were classified as long-term debt at December 31, 2015 as the Partnership repaid these notes in May 2016 with borrowings under its $2.50 billion Credit Facility, due in 2020. (4) Represents fair value adjustments on senior notes resulting from the application of push-down accounting in connection with the acquisition of the Partnership's general partner by ETP on October 5, 2012. (5) In the fourth quarter 2015, the Partnership adopted accounting guidance which requires certain debt issuance costs to be reflected as a reduction in the total long-term debt liability for all periods presented. The net long-term debt balance now includes $ 34 and $ 32 million of debt issuance costs at December 31, 2016 and 2015, respectively. The aggregate amount of long-term debt instrument maturities are as follows: Year Ended December 31, (in millions) 2017 $ 630 2018 — 2019 — 2020 1,542 2021 600 Thereafter 4,500 Total $ 7,272 Cash payments for interest related to long-term debt instruments, net of capitalized interest (Note 2), were $ 152 , $ 137 , and $ 64 million for the years ended December 31, 2016, 2015 and 2014, respectively. Credit Facilities In March 2015, the Operating Partnership amended and restated its $ 1.50 billion Credit Facility, which was scheduled to mature in November 2018. The amended and restated credit facility is a $ 2.50 billion unsecured revolving credit agreement (the "$2.50 billion Credit Facility"), which matures in March 2020, will continue to fund the Partnership's working capital requirements, finance acquisitions and capital projects, and be used for general partnership purposes. The $2.50 billion Credit Facility contains an "accordion" feature, under which the total aggregate commitment may be extended to $ 3.25 billion under certain conditions. In June 2015, the $2.50 billion Credit Facility was amended to create a segregated tranche of borrowings that will be guaranteed by ETP. The amendment did not modify the outstanding borrowings, total capacity or terms of the facility. In September 2015, the Operating Partnership initiated a commercial paper program under the borrowing limits established by its $2.50 billion Credit Facility. The facility bears interest at LIBOR or the Base Rate, as defined in the facility, each plus an applicable margin. The credit facility may be repaid at any time. The $2.50 billion Credit Facility contains various covenants including limitations on the creation of indebtedness and liens, and related to the operation and conduct of the business of the Partnership and its subsidiaries. The credit facility also limits the Partnership, on a rolling four quarter basis, to a maximum total consolidated debt to consolidated Adjusted EBITDA ratio, as defined in the underlying credit agreement, of 5.0 to 1, which can generally be increased to 5.5 to 1 during an acquisition period. The Partnership's ratio of total consolidated debt to consolidated Adjusted EBITDA was 4.4 to 1 at December 31, 2016, as calculated in accordance with the credit agreement. In December 2016, the Operating Partnership entered into an agreement for a 364-day maturity credit facility ("364-Day Credit Facility") with a total lending capacity of $ 1.0 billion, including a $ 630 million term loan. The terms of the 364-Day Credit Facility are similar to those of the $2.50 billion Credit Facility, including limitations on the creation of indebtedness, liens and financial covenants. The 364-Day Credit Facility is used to fund the Partnership's working capital requirements and for general partnership purposes. The facility bears interest at LIBOR or the Base Rate, as defined in the facility, each plus an applicable margin. The credit facility may be repaid at any time, and is expected to be terminated and repaid in connection with completion of the Merger. See Note 8 for additional information on the Bakken Pipeline project-level financing. Senior Notes The Operating Partnership had $ 175 million of 6.125 percent Senior Notes which matured and were repaid in May 2016, using borrowings under the $2.50 billion Credit Facility. In July 2016, the Operating Partnership issued $ 550 million of 3.90 percent Senior Notes (the "2026 Senior Notes"), due July 2026. In November 2015, the Partnership issued $ 600 million of 4.40 percent senior notes and $ 400 million of 5.95 percent senior notes (the "2021 and 2025 Senior Notes"), due April 2021 and December 2025, respectively. The net proceeds of $ 544 and $ 991 million from the 2016 and 2015 senior notes offerings, respectively, were used to repay outstanding borrowings on the $2.50 billion Credit Facility and for general partnership purposes. The terms and conditions of these senior notes offerings are comparable to those under other outstanding senior notes. Debt Guarantee The Partnership currently serves as guarantor of the senior notes and of any obligations under its credit facilities. This guarantee is full and unconditional. See Note 20 for supplemental condensed consolidating financial information.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Commitments and Contingent Liabilities Total rental expense for the years ended December 31, 2016, 2015 and 2014 amounted to $ 22 , $ 22 , and $ 18 million, respectively. The Partnership, as lessee, has non-cancelable operating leases for office space and equipment for which the aggregate amount of future minimum annual rentals as of December 31, 2016 is as follows: Year Ended December 31, (in millions) 2017 $ 7 2018 4 2019 3 2020 3 2021 — Thereafter — Total $ 17 The Partnership is subject to numerous federal, state and local laws which regulate the discharge of materials into the environment or that otherwise relate to the protection of the environment. These laws and regulations result in liabilities and loss contingencies for remediation at the Partnership's facilities and at third-party or formerly owned sites. At December 31, 2016 and 2015, there were accrued liabilities for environmental remediation in the consolidated balance sheets of $ 4 and $ 6 million, respectively. The accrued liabilities for environmental remediation do not include any amounts attributable to unasserted claims, since there are no unasserted claims that are probable of settlement or reasonably estimable, nor have any recoveries from insurance been assumed. Charges against income for environmental remediation totaled $ 10 , $ 8 , and $ 15 , million for the years ended December 31, 2016, 2015 and 2014, respectively. The Partnership maintains insurance programs that cover certain of its existing or potential environmental liabilities. Claims for recovery of environmental liabilities and previous expenditures that are probable of realization were not material in relation to the Partnership's consolidated financial position at December 31, 2016 and 2015. Total future costs for environmental remediation activities will depend upon, among other things, the identification of any additional sites; the determination of the extent of the contamination at each site; the timing and nature of required remedial actions; the technology available and needed to meet the various existing legal requirements; the nature and extent of future environmental laws, inflation rates and the determination of the Partnership's liability at multi-party sites, if any, in light of uncertainties with respect to joint and several liability; and the number, participation levels and financial viability of other parties. Management believes it is reasonably possible that additional environmental remediation losses will be incurred. At December 31, 2016, the aggregate of the estimated maximum additional reasonably possible losses, which relate to numerous individual sites, totaled $ 13 million. The Partnership is a party to certain pending and threatened claims. Although the ultimate outcome of these claims cannot be ascertained at this time, nor can a range of reasonably possible losses be determined, it is reasonably possible that some portion of them could be resolved unfavorably to the Partnership. Management does not believe that any liabilities which may arise from such claims and the environmental matters discussed above would be material in relation to the Partnership's results of operations, financial position or cash flows at December 31, 2016. Furthermore, management does not believe that the overall costs for such matters will have a material impact, over an extended period of time, on the Partnership's financial position, results of operations or cash flows. Sunoco has indemnified the Partnership for 30 years from environmental and toxic tort liabilities related to the assets contributed to the Partnership, that arose from the operation of such assets prior to the closing of the February 2002 initial public offering ("IPO"). Sunoco has also indemnified the Partnership for 100 percent of all losses asserted within the first 21 years after the closing of the IPO. Sunoco's share of liability for claims asserted thereafter will decrease by 10 percent per year. For example, for a claim asserted during the twenty-third year after closing of the IPO, Sunoco would be required to indemnify the Partnership for 80 percent of its loss. There is no monetary cap on the amount of indemnity coverage provided by Sunoco. The Partnership has agreed to indemnify Sunoco for events and conditions associated with the operation of the Partnership's assets that occur on or after the closing of the IPO and for environmental and toxic tort liabilities to the extent Sunoco is not required to indemnify the Partnership. Management of the Partnership does not believe that any liabilities which may arise from claims indemnified by Sunoco would be material in relation to the Partnership's financial position, results of operations or cash flows at December 31, 2016. There are certain other pending legal proceedings related to matters arising after the IPO that are not indemnified by Sunoco. Management believes that any liabilities that may arise from these legal proceedings will not be material in relation to the Partnership's financial position, results of operations or cash flows at December 31, 2016.

Equity

Equity [Abstract]
Equity	Equity The Partnership maintains an at-the-market equity offering program which allows the Partnership to issue common units directly to the public and raise capital in a timely and efficient manner to finance its growth capital program, while supporting the Partnership's investment-grade credit ratings. For the years ended December 31, 2016 and 2015, the Partnership issued 29.1 and 26.8 million common units under this program, for proceeds of $ 744 and $ 890 million, net of $ 8 and $ 10 million in fees and commissions to managers, respectively. In September and October 2016, a total of 24.2 million common units were issued for total proceeds of $ 652 million in connection with a public offering and related option exercise. The proceeds from this offering were used to partially fund the acquisition from Vitol. In March and April 2015, a total of 15.5 million common units were issued in connection with a public offering and related option exercise. Total proceeds of $ 648 million were used to repay outstanding borrowings under the Partnership's $ 2.50 billion Credit Facility and for general partnership purposes. Formation of Permian Express Partners In February 2017, the Partnership formed Permian Express Partners LLC ("PEP"), a strategic joint venture, with ExxonMobil. The Partnership contributed its Permian Express 1, Permian Express 2 and Permian Longview and Louisiana Access pipelines. ExxonMobil contributed its Longview to Louisiana and Pegasus pipelines; Hawkins gathering system; an idle pipeline in southern Oklahoma; and its Patoka, Illinois terminal. The Partnership's ownership percentage, upon formation, is approximately 85 percent. Upon commencement of operations on the Bakken pipeline, the Partnership will contribute its investment in the project, with a corresponding increase in its ownership percentage in PEP. The Partnership maintains a controlling financial and voting interest in PEP and is the operator of all of the assets. As such, PEP will be reflected as a consolidated subsidiary of the Partnership with its operating results included in the Crude Oil segment. ExxonMobil's interest will be reflected as a noncontrolling interest in the Partnership's consolidated balance sheets.

Cash Distributions

Cash Distributions	12 Months Ended

Equity [Abstract]
Cash Distributions	Cash Distributions Within 45 days after the end of each quarter, the Partnership distributes all cash on hand at the end of the quarter, less reserves established by the general partner in its discretion. This is defined as "available cash" in the partnership agreement. The general partner has broad discretion to establish cash reserves that it determines are necessary or appropriate to properly conduct the Partnership's business. The Partnership will make quarterly distributions to the extent there is sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to the general partner. If cash distributions exceed $0.0833 per unit in a quarter, the general partner receives increasing percentages, up to 50 percent , of the cash distributed in excess of that amount. These distributions are referred to as "incentive distributions." The percentage interests shown for the unitholders and the general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The following table shows the target distribution levels and distribution "splits" between the general partner and the holders of the Partnership's common units at December 31, 2016: Total Quarterly Distribution Target Amount Marginal Percentage Interest in Distributions General Partner Unitholders Minimum Quarterly Distribution $0.0750 1 % 99% First Target Distribution up to $0.0833 1 % 99% Second Target Distribution above $0.0833 up to $0.0958 14 % (1) 86% Third Target Distribution above $0.0958 up to $0.2638 36 % (1) 64% Thereafter above $0.2638 49 % (1) 51% (1) Includes general partner interest.

The reductions will total $ 60 million over a two-year period, recognized ratably over eight quarters, and began with the third quarter 2016 cash distribution. On January 26, 2017, the Partnership declared a cash distribution of $ 0.52 per unit ($ 2.08 per unit, annualized) on its outstanding common units, representing the distribution for the quarter ended December 31, 2016. The $ 272 million distribution, including $ 105 million to the general partner, was paid on February 14, 2017 to unitholders of record at the close of business on February 7, 2017.

Management Incentive Plan

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Management Incentive Plan	Management Incentive Plan In December 2015, the Partnership's unitholders approved the Sunoco Partners LLC Long-Term Incentive Plan, as amended and restated (the "Restated LTIP"), which was previously approved by the board of directors of Sunoco Partners LLC, the Partnership's general partner. The Restated LTIP authorized an additional 10.0 million common units to be available under the plan; added additional types of awards that can be granted under the plan, such as phantom unit awards, unit appreciation rights, unrestricted unit awards and other unit-based awards ("plan awards"); added a prohibition on repricing of unit options and unit appreciation rights without the approval of the unitholders; provided for termination of the plan at the earliest date it is terminated by the board of directors, the date no more units remain available for grants, and December 1, 2025; and incorporated certain other administrative changes. The Restated LTIP benefits eligible employees and directors of the general partner and its affiliates who perform services for the Partnership. The Restated LTIP is administered by the independent directors of the Compensation Committee of the general partner's board of directors with respect to employee awards, and by the general partner's board of directors with respect to awards granted to the independent directors. At December 31, 2016, there were 8.6 million plan awards available for future grants under the Restated LTIP. Restricted Units A restricted unit entitles the grantee to receive a common unit or, at the discretion of the Compensation Committee, an amount of cash equivalent to the value of a common unit upon the vesting of the unit. Such grants may include requirements related to the attainment of predetermined performance targets. The Compensation Committee may make additional grants under the Restated LTIP to employees and directors containing such terms as defined by the Compensation Committee. Common units to be delivered to the grantee upon vesting may be common units acquired by the general partner in the open market, common units already owned by the general partner, common units acquired by the general partner directly from the Partnership or any other person, or any combination of the foregoing. The general partner will be entitled to reimbursement by the Partnership for the cost incurred in acquiring common units. If the Partnership issues new common units upon vesting of the restricted units, the total number of common units outstanding will increase. The Compensation Committee, at its discretion, may grant tandem distribution equivalent rights ("DERs") related to the restricted units. Subject to applicable vesting criteria, DERs entitle the grantee to receive an amount of cash equal to the per unit cash distributions made by the Partnership during the period the restricted unit is outstanding. All units granted during the periods presented below included tandem DERs. The Partnership's outstanding restricted unit awards are time-vested grants, the vesting of which occurs over a five -year period, and is conditioned solely upon continued employment or service as of the applicable vesting date. The following table summarizes information regarding restricted unit award activity for the periods presented: Number of Units Weighted Average Grant Date Fair Value Granted, non-vested and outstanding, December 31, 2013 1,279,162 $ 26.19 Granted 719,009 $ 41.59 Performance factor adjustment (1) 229,828 $ 17.52 Vested (693,326 ) $ 20.26 Cancelled/forfeited (72,872 ) $ 30.10 Granted, non-vested and outstanding, December 31, 2014 1,461,801 $ 35.01 Granted 1,412,257 $ 29.54 Vested (245,563 ) $ 22.08 Cancelled/forfeited (90,776 ) $ 36.83 Granted, non-vested and outstanding, December 31, 2015 2,537,719 $ 33.16 Granted 1,300,255 $ 23.21 Vested (526,014 ) $ 34.19 Cancelled/forfeited (98,440 ) $ 33.72 Granted, non-vested and outstanding, December 31, 2016 3,213,520 $ 28.57 (1) Certain awards granted prior to October 5, 2012 were subject to the Partnership achieving certain market-based and cash distribution performance targets as compared to a peer group average, or certain cash distribution performance targets as defined by the Compensation Committee, which caused the actual amount of units that ultimately vested to range between 0 to 200 percent of the original units granted. The total fair value of restricted unit awards vested for the years ended December 31, 2016, 2015 and 2014, was $ 12 , $ 8 , and $ 30 million, respectively, based on the market price of the Partnership's common units as of the vesting date. As of December 31, 2016, estimated compensation cost related to non-vested awards not yet recognized was $ 57 million, and the weighted average period over which this cost is expected to be recognized in expense is 3.0 years. The fair value of the Partnership's time-vested awards is based on the grant date market price of the Partnership's common units. The Partnership recognizes compensation expense on a straight-line basis over the requisite service period, and estimates forfeitures over the requisite service period when recognizing compensation expense. Based on the unit grants and performance factor adjustments outlined in the table above, the Partnership recognized unit-based compensation expense related to the awards granted within operating expenses and selling, general and administrative expenses in the consolidated statements of comprehensive income of $ 23 , $ 17 , and $ 16 million for the years ended December 31, 2016, 2015 and 2014, respectively. The tandem DERs associated with the restricted unit grants are recognized as a reduction of equity when earned.

Derivatives and Risk Management

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Risk Management	Derivatives and Risk Management The Partnership is exposed to various risks, including volatility in the prices of the products that the Partnership markets, counterparty credit risk and changes in interest rates. Price Risk Management The Partnership is exposed to risks associated with changes in the market price of crude oil, NGLs and refined products. These risks are primarily associated with price volatility related to pre-existing or anticipated purchases, sales and storage. Price changes are often caused by shifts in the supply and demand for these commodities, as well as their locations. In order to manage such exposure, the Partnership's policy is (i) to only purchase crude oil, NGLs and refined products for which sales contracts have been executed or for which ready markets exist, (ii) to structure sales contracts so that price fluctuations do not materially impact the margins earned, and (iii) to not acquire and hold physical inventory, futures contracts or other derivative instruments for the purpose of speculating on commodity price changes. Although the Partnership seeks to maintain a balanced inventory position within its commodity inventories, net unbalances may occur for short periods of time due to production, transportation and delivery variances. When physical inventory builds or draws do occur, the Partnership continuously manages the variance to a balanced position over a period of time. The physical contracts related to the Partnership's commodity purchase and sale activities that qualify as derivatives have been designated as normal purchases and sales and are accounted for using accrual accounting under United States' generally accepted accounting principles. The Partnership accounts for derivatives that do not qualify as normal purchases or sales at fair value. The Partnership currently does not utilize derivative instruments to manage its exposure to prices related to crude oil sale activities. All derivative balances are presented on a gross basis. Pursuant to the Partnership's approved risk management policy, derivative contracts, such as swaps, futures and other derivative instruments, may be used to hedge or reduce exposure to price risk associated with acquired inventory or forecasted physical transactions. The Partnership utilizes derivative instruments to mitigate the risk associated with market movements in the price of crude oil, NGLs, refined products, and other commodities as necessary. These derivative contracts act as a hedging mechanism against the volatility of prices by allowing the Partnership to transfer this price risk to counterparties who are able and willing to bear it. The Partnership has no derivative contracts designated as hedges for accounting purposes. Therefore, all realized and unrealized gains and losses from these derivative contracts are recognized in the consolidated statement of comprehensive income in the period in which they occur. All realized gains and losses associated with the Partnership's derivative contracts are recorded in earnings in the same line item associated with the forecasted transaction (either sales and other operating revenue, cost of products sold or operating expenses). The Partnership had open derivative positions on 9.2 million barrels of crude oil, NGLs and refined products at December 31, 2016 and 2015. The derivatives outstanding at December 31, 2016 vary in duration but do not extend beyond one year. The Partnership records its derivatives at fair value based on observable market prices (levels 1 and 2), of which positions at December 31, 2016 and 2015 were primarily categorized at level 2. As of December 31, 2016 and 2015, the fair values of the Partnership's derivative assets and liabilities were: December 31, 2016 2015 (in millions) Derivative assets $ 19 $ 30 Derivative liabilities (46 ) (18 ) $ (27 ) $ 12 Derivative asset and liability balances are recorded in accounts receivable and accrued liabilities, respectively, in the consolidated balance sheets. The following table sets forth the impact of derivatives on the Partnership's results of operations for the periods presented: Location of Gains (Losses) Recognized in Earnings Gains (Losses) Recognized in Earnings (in millions) Year Ended December 31, 2016 Derivatives not designated as hedging instruments: Commodity contracts Sales and other operating revenue $ (65 ) Commodity contracts Cost of products sold 6 $ (59 ) Year Ended December 31, 2015 Derivatives not designated as hedging instruments: Commodity contracts Sales and other operating revenue $ 47 Commodity contracts Cost of products sold (26 ) Commodity contracts Operating expenses (1 ) $ 20 Year Ended December 31, 2014 Derivatives not designated as hedging instruments: Commodity contracts Sales and other operating revenue $ 81 Commodity contracts Cost of products sold (20 ) $ 61 Credit Risk Management The Partnership maintains credit policies with regard to its counterparties that management believes minimize the overall credit risk through credit analysis, credit approvals, credit limits and monitoring procedures. The credit positions of the Partnership's customers are analyzed prior to the extension of credit and periodically after credit has been extended. The Partnership's counterparties consist primarily of financial institutions and major integrated oil companies. This concentration of counterparties may impact the Partnership's overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. Interest Rate Risk Management The Partnership has interest rate risk exposure for changes in interest rates related to its outstanding borrowings. The Partnership manages its exposure to changes in interest rates through the use of a combination of fixed-rate and variable-rate financial instruments. At December 31, 2016, the Partnership had $ 1.9 billion of consolidated variable-rate borrowings under its credit facilities, including $ 50 million of commercial paper products and the $ 630 million term loan.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Measurements The estimated fair value of the Partnership's financial instruments has been determined based on management's assessment of available market information and appropriate valuation methodologies. The Partnership's current assets (other than derivatives and inventories) and current liabilities (other than derivatives) are financial instruments and most of these items are recorded at cost in the consolidated balance sheets. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. The Partnership's derivatives are measured and recorded at fair value based on observable market prices. The estimated fair value of the Partnership's senior notes is determined using observable market prices, as these notes are actively traded (level 1). The estimated aggregate fair value of the senior notes at December 31, 2016 was $ 5.4 billion, compared to the carrying amount of $ 5.4 billion. The estimated aggregate fair value of the senior notes at December 31, 2015 was $ 4.2 billion, compared to the carrying amount of $ 5.1 billion.

Concentration of Credit Risk

Risks and Uncertainties [Abstract]
Concentration Risk Disclosure	Concentration of Credit Risk The Partnership's trade relationships are primarily with major integrated oil companies, independent oil companies and other pipelines and wholesalers. These concentrations of customers may affect the Partnership's overall credit risk as the customers may be similarly affected by changes in economic, regulatory or other factors. The Partnership maintains credit policies with regard to its counterparties that management believes minimize the overall credit risk through credit analysis, credit approvals, credit limits and monitoring procedures. The credit positions of the Partnership's customers are analyzed prior to the extension of credit and periodically after it has been extended. For certain transactions, the Partnership may utilize letters of credit, prepayments, guarantees and secured interests in assets. In 2016, approximately 12 percent of the Partnership's total revenues, respectively, were derived from one investment-grade customer with crude oil sales and other revenues comprising greater than 10 percent of total revenues. In 2015, approximately 23 percent of the Partnership's total revenues were derived from two investment-grade customers with crude oil sales and other revenues. While this concentration has the ability to negatively impact revenues going forward, management does not anticipate a material adverse effect in the Partnership's financial position, results of operations or cash flows as the absolute price levels for crude oil normally do not bear a relationship to gross profit. In addition, these customers are subject to netting arrangements which allow the Partnership to offset payable activities and mitigate credit exposure.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information The Partnership operates in 37 states throughout the United States and in three principal business segments. During the fourth quarter 2015, the Partnership realigned its reporting segments as a result of the continued investment in its organic growth capital program which has served to increase the integration that exists between its assets that service each commodity. This has also resulted in a shift in Management's strategic decision making process, resource allocation methodology, and assessment of the Partnership's financial results. The updated reporting segments are: Crude Oil, Natural Gas Liquids and Refined Products. The new segmentation provides the Partnership's investors with a more meaningful view of its business that is consistent with that of Management. For the purpose of comparability, all prior year segment disclosures have been recast to conform to the current presentation. Such recasts had no impact on previously reported consolidated earnings. • The Crude Oil segment provides transportation, terminalling and acquisition and marketing services to crude oil markets throughout the southwest, midwest and northeastern United States. Included within the segment is approximately 6,100 miles of crude oil trunk and gathering pipelines in the southwest and midwest United States and equity ownership interests in two crude oil pipelines. Our crude oil terminalling services operate with an aggregate storage capacity of approximately 33 million barrels, including approximately 26 million barrels at our Gulf Coast terminal in Nederland, Texas, approximately 2 million barrels at our Midland, Texas terminal and approximately 3 million barrels at our Fort Mifflin terminal complex in Pennsylvania. Our crude oil acquisition and marketing activities utilize our pipeline and terminal assets, our proprietary fleet of crude oil tractor trailers and truck unloading facilities, as well as third-party assets, to service crude oil markets principally in the mid-continent United States. • The Natural Gas Liquids segment transports, stores, and executes acquisition and marketing activities utilizing a complementary network of pipelines, storage and blending facilities, and strategic off-take locations that provide access to multiple NGLs markets. The segment contains approximately 900 miles of NGLs pipelines, primarily related to our Mariner systems located in the northeast and southwest United States. Terminalling services are facilitated by approximately 5 million barrels of NGLs storage capacity, including approximately 1 million barrels of storage at our Nederland, Texas terminal facility and 3 million barrels at our Marcus Hook, Pennsylvania terminal facility (the "Marcus Hook Industrial Complex"). This segment also carries out our NGLs blending activities, including utilizing our patented butane blending technology. • The Refined Products segment provides transportation and terminalling services, utilizing approximately 1,800 miles of refined products pipelines and approximately 40 active refined products marketing terminals. Our marketing terminals are located primarily in the northeast, midwest and southwest United States, with approximately 8 million barrels of refined products storage capacity. The Refined Products segment includes our Eagle Point facility in New Jersey, which has approximately 6 million barrels of refined products storage capacity. The segment also includes our equity ownership interests in four refined products pipeline companies. The segment also performs terminalling activities at our Marcus Hook Industrial Complex. The Refined Products segment utilizes our integrated pipeline and terminalling assets, as well as acquisition and marketing activities, to service refined products markets in several regions of the United States.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements reflect the results of the Partnership and its wholly-owned subsidiaries, including Sunoco Logistics Partners Operations L.P. (the "Operating Partnership"), the proportionate shares of the Partnership's undivided interests in assets, and the accounts of entities in which the Partnership has a controlling financial interest. A controlling financial interest is evidenced by either a voting interest greater than 50 percent or a risk and rewards model that identifies the Partnership or one of its subsidiaries as the primary beneficiary of a variable interest entity. The Partnership currently holds a controlling financial interest in Inland Corporation ("Inland"), Mid-Valley Pipeline Company ("Mid-Valley"), Price River Terminal, LLC ("PRT"), and, effective February 1, 2017, Permian Express Partners LLC ("PEP"), which is a joint venture with ExxonMobil. These entities are reflected as consolidated subsidiaries of the Partnership. Effective November 1, 2016, SunVit Pipeline LLC ("SunVit") became a wholly-owned subsidiary of the Partnership in connection with the acquisition from Vitol Inc. The Partnership is not the primary beneficiary of any variable-interest entities ("VIEs"). All significant intercompany accounts and transactions are eliminated in consolidation and noncontrolling interests in net income and equity are shown separately in the consolidated statements of comprehensive income and balance sheets. Equity ownership interests in joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, are accounted for under the equity method of accounting.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates.
Reclassifications	Reclassification Certain amounts in the prior years' consolidated financial statements have been reclassified to conform to the current year presentation. The changes did not impact reported net income for any periods presented.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, which created Topic 842, Leases, and will supersede the requirements in Topic 840. The objective of ASU 2016-02 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Partnership is currently evaluating the impact that it will have on its consolidated financial statements and related disclosures. In May 2014, the FASB codified guidance in ASU 2014-09 related to the recognition of revenue from contracts with customers, and has since released associated clarifying guidance in subsequent periods. The new standards outline the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods, with early adoption permitted.
Revenue Recognition	Revenue Recognition Pipeline revenues are recognized upon delivery of the barrels to the location designated by the shipper. Acquisition and marketing revenues for crude oil, NGLs and refined products are recognized when title to and risk of loss of the product is transferred to the customer. Terminalling and storage revenues are recognized at the time the services are provided. Revenues are not recognized for exchange transactions, which are entered into primarily to acquire a commodity of a desired quality or to reduce transportation costs by taking delivery closer to the Partnership's end markets. Any net differential for exchange transactions is recorded as an adjustment to cost of products sold in the consolidated statements of comprehensive income. Affiliated revenues are generated from sales of crude oil, NGLs and refined products, as well as pipeline transportation, terminalling and storage services to ETP and its affiliates. Sales of crude oil, NGLs and refined products to affiliated entities are priced using market-based rates. Affiliated entities pay fees for transportation or terminalling services based on the terms and conditions of established agreements or published tariffs.
Cash Equivalents	Cash Equivalents The Partnership considers all highly liquid investments with a remaining maturity of three months or less at the time of purchase to be cash equivalents. At December 31, 2016 and 2015, cash equivalents consisted of time deposits and money market investments.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable represent valid claims against non-affiliated customers (see Note 4 for affiliated receivables) for products sold or services rendered. The Partnership extends credit terms to certain customers after review of various credit indicators, including the customers' credit ratings. Outstanding customer receivable balances are regularly reviewed for possible non-payment indicators and reserves are recorded for doubtful accounts based upon management's expectations regarding collectability. Actual receivable balances are charged against the reserve when all collection efforts have been exhausted.
Inventories	Inventories Inventories are valued at the lower of cost or market. Crude oil, NGLs and refined products inventory costs have been determined using the last-in, first-out method ("LIFO"). Under this methodology, the cost of products sold consists of the actual acquisition costs of the Partnership, which include transportation and storage costs. Such costs are adjusted to reflect increases or decreases in inventory quantities, which are valued based on the changes in the LIFO inventory layers. The cost of materials, supplies and other inventories is principally determined using the average-cost method. During the periods ended December 31, 2016, 2015 and 2014, a lower of cost or market ("LCM") adjustment was applied, as necessary, to the Partnership's crude oil, NGLs and refined products inventories due to changes in commodity prices. Adjustments are calculated based upon current replacement costs. See Notes 6 and 18 for additional information on the LCM reserves and their impact to the Partnership's net income.
Properties, Plants and Equipment	Properties, Plants and Equipment Properties, plants and equipment are stated at cost. Additions to properties, plants and equipment, including replacements and improvements, are recorded at cost. Repair and maintenance expenditures are charged to expense as incurred. Depreciation is determined principally using the straight-line method based on the estimated useful lives of the related assets. For certain interstate pipelines, the depreciation rate is applied to the net asset value based on the Federal Energy Regulatory Commission's ("FERC") requirements, which approximates the estimated useful lives of the related assets.
Capitalized Interest	Capitalized Interest The Partnership capitalizes interest incurred on funds borrowed for certain capital projects and contributions to joint venture interests during periods in which construction activities are in progress to bring those projects to their intended use.
Investment in Affiliates	Investment in Affiliates Investment in affiliates, which consist of joint ventures in which the Partnership does not have a controlling financial interest, but over which the Partnership can exercise significant influence, are accounted for under the equity method of accounting. Under this method, an investment is carried at cost, adjusted for the equity in income (loss), reduced for dividends received and adjusted for changes in accumulated other comprehensive income (loss). Income recognized from the Partnership's joint venture interests is presented within other income in the consolidated statements of comprehensive income. The Partnership allocates the excess of its investment cost over its equity in the net assets of affiliates to the underlying tangible and intangible assets of the joint ventures. Other than land and indefinite-lived intangible assets, all amounts allocated, principally to pipeline and related assets, are amortized using the straight-line method over their estimated useful life of 40 years . The amortization of these amounts is also presented within other income in the consolidated statements of comprehensive income.
Acquisitions	Acquisitions The Partnership records third-party business combinations at their estimated fair values as of the date of acquisition. Any excess of consideration transferred plus the fair value of noncontrolling interest over the estimated fair value of the net assets acquired is recorded as goodwill. To the extent the estimated fair value of the net assets acquired exceeds the purchase price plus the fair value of the noncontrolling interest, a gain is recorded in results of current operations. The results of operations of acquired businesses are included in the Partnership's results from the dates of acquisition. Assets acquired and liabilities assumed include tangible and intangible assets, and contingent assets and liabilities. The estimated fair values of these assets and liabilities are determined based on observable inputs such as quoted market prices, information from comparable transactions, offers made by other prospective acquirers in the cases where the Partnership has certain rights to acquire additional interests in existing investments, and the replacement cost of assets in the same condition or stage of usefulness; or on unobservable inputs such as expected future cash flows or internally developed estimates of value. The Partnership's fair value measurements are classified within the fair value hierarchy established by GAAP based on the lowest level (least observable) input that is significant to the measurement in its entirety. Assets acquired and liabilities assumed in connection with acquisitions from entities under common control are recorded by the Partnership at the common control entity's net carrying value. The Partnership records any difference between the consideration paid and the carrying value of the net assets and liabilities as a distribution from, or contribution to, redeemable limited partner interests or equity, as applicable. The Partnership's asset acquisitions are recorded at the purchase price, which is allocated to the acquired assets and assumed liabilities based on their relative estimated fair values. See Note 3 for additional information concerning the Partnership's recent acquisitions.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets, other than those held for sale, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An asset is considered to be impaired when the undiscounted estimated net cash flows expected to be generated by the asset are less than its carrying amount. The impairment recognized is the amount by which the carrying amount exceeds the estimated fair value of the impaired asset. Long-lived assets held for sale are recorded at the lower of their carrying amount or estimated fair value less cost to sell the assets.
Goodwill	Goodwill Goodwill, which represents the excess of the purchase price in a business combination over the fair value of net assets acquired, is tested for impairment annually in the fourth quarter, or more often if events or changes in circumstances indicate that the carrying value of goodwill may exceed its estimated fair value. The Partnership's general partner was acquired and became a consolidated subsidiary of ETP in the fourth quarter 2012. In connection with the acquisition, the Partnership elected to apply "push-down accounting" which required the Partnership's assets and liabilities to be adjusted to fair value on the closing date of the acquisition, which included an increase to the Partnership's goodwill balance of approximately $ 1.3 billion. Management's process for evaluating goodwill for impairment involves estimating the fair value of the Partnership's reporting units that include goodwill. Inherent in estimating fair value for each reporting unit are certain judgments and estimates relating the market multiples for comparable businesses, management's interpretation of current economic indicators, and market conditions and assumptions about the Partnership's strategic plans with regards to its operations. To the extent additional information arises, market conditions change or the Partnership's strategies change, it is possible the conclusion regarding whether the goodwill is impaired could change and result in future goodwill impairment charges. During the fourth quarter 2015, the Partnership realigned its reporting segments and, in accordance with accounting guidance, was required to test its goodwill balance for impairment both before and after the change in its reportable segments. Due to volatility within the energy markets, the Partnership utilized the assistance of a third party valuation firm to develop models to estimate the fair value of each of its reporting units that contain goodwill. The fair value of the reporting units was estimated using a combination of discounted cash flow and market multiple methodologies. Under the discounted cash flow methodology, fair value was estimated using the present value of Management's projected cash flows for each reporting unit which was calculated using the expected return a market participant would require for each reporting unit. Under the market multiple methodology, a selection of peer group companies, which are similar from an operational or industry perspective, were considered in estimating market multiples. These multiples were applied to Management's projected Adjusted EBITDA in order to estimate fair value. For the 2015 impairment test, the fair value of the Partnership's legacy Crude Oil Acquisition and Marketing segment was determined to be approximately 3 percent less than its carrying value. In accordance with accounting guidance, a second test was performed to estimate the fair value of the reporting unit's assets and liabilities, which included determining an implied goodwill value. The Partnership performed the second test and determined that the implied fair value of the Crude Oil Acquisition and Marketing segment's goodwill exceeded its current carrying value. See Note 9 for additional information on the Partnership's goodwill balance.
Intangible Assets	Intangible Assets The Partnership has acquired intangible assets, such as customer relationships and patents related to butane blending technology. The value assigned to these intangible assets is amortized on a straight-line basis over their respective economic lives through depreciation and amortization expense in the consolidated statements of comprehensive income.
Environmental Remediation	Environmental Remediation The Partnership accrues environmental remediation costs for work at identified sites where an assessment has indicated that cleanup costs are probable and reasonably estimable. Such accruals are undiscounted and are based on currently available information, estimated timing of remedial actions and related inflation assumptions, existing technology and presently enacted laws and regulations. If a range of probable environmental cleanup costs exists for an identified site, the minimum of the range is accrued unless some other point or points in the range are more likely, in which case the most likely amount in this range is accrued.
Income Taxes	Income Taxes The Partnership is not a taxable entity for U.S. federal income tax purposes, or for the majority of states that impose income taxes. Rather, income taxes are generally assessed at the partner level. There are some states in which the Partnership operates where it is subject to state and local income taxes. Substantially all of the income tax amounts reflected in the Partnership's consolidated financial statements are related to the operations of Inland, Mid-Valley and West Texas Gulf Pipe Line Company ("West Texas Gulf"), all of which are subject to income taxes for federal and state purposes at the corporate level. The effective tax rates for these entities approximate the federal statutory rate of 35 percent . The Partnership recognizes a tax benefit from uncertain positions only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authorities' widely understood administrative practices and precedents. The tax benefits recognized from such positions are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement.
Long-Term Incentive Plan	Long-Term Incentive Plan The Partnership accounts for the compensation cost associated with all unit-based payment awards at grant-date fair value and reports the related expense within operating expenses and selling, general and administrative expenses in the consolidated statements of comprehensive income. Unit-based compensation cost for all outstanding awards of restricted units is based on the grant date market price of the underlying unit. The Partnership recognizes unit-based compensation expense on a straight-line basis over the requisite service period. In accordance with the terms of certain awards, the recognition of compensation expense is accelerated for participants who become retirement-eligible during the applicable vesting period.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations ("AROs") represent the fair value of expected liabilities related to the future retirement of long-lived assets and are recorded at the time in which a legal obligation is incurred. A corresponding asset is recorded concurrently and is depreciated over the anticipated active life of the related long-lived asset. The value of the ARO is determined based on estimates and assumptions regarding ongoing maintenance and repair, asset repurposing costs, disposal costs and associated contractual obligations related to the Partnership's pipelines, terminal facilities, storage tanks, truck and leased assets. The Partnership bases these estimates on historical and budgeted costs, future inflation rates and credit-adjusted risk-free interest rates. These fair value assessments are considered to be level 3 measurements, as they are based on both observable and unobservable inputs. The Partnership's consolidated balance sheets include AROs as a component of other deferred credits and liabilities of $ 88 million at December 31, 2016 and 2015. The Partnership believes it may have additional asset retirement obligations related to its pipeline assets and storage tanks for which it is not possible to estimate whether or when the retirement obligations will be settled. Consequently, these retirement obligations cannot be measured at this time.
Fair Value Measurements	Fair Value Measurements The Partnership determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Partnership utilizes valuation techniques that maximize the use of observable inputs (levels 1 and 2) and minimize the use of unobservable inputs (level 3) within the fair value hierarchy established by the FASB. Where quoted pricing is not available, the Partnership utilizes a "market" or "income" approach to determine fair value. This method uses pricing and other information related to market transactions for identical or comparable assets and liabilities. Assets and liabilities are classified within the fair value hierarchy based on the lowest level (least observable) input that is significant to the measurement in its entirety.
Lease Accounting	Lease Accounting The Partnership accounts for arrangements that convey the right to use property, plant or equipment for a stated period of time as leases. Whether an arrangement contains a lease is determined at inception of the arrangement based on all of the facts and circumstances. The Partnership reassesses whether an arrangement contains a lease after the inception of the arrangement only if (a) there is a change in the contractual terms, (b) a renewal option is exercised or an extension is agreed to by the parties to the arrangement, (c) there is a change in the determination of whether or not fulfillment is dependent on specified property, plant, or equipment, or (d) there is a substantial physical change to the specified property, plant, or equipment. The Partnership continually analyzes its new and existing arrangements to evaluate whether they contain leases. Revenue or expense from arrangements where the Partnership is the lessor or lessee, respectively, is recognized ratably over the term of the underlying arrangement.
Net Income Attributable to Sunoco Logistics Partners L.P. Per Limited Partner Unit	Net Income Attributable to Sunoco Logistics Partners L.P. per Limited Partner Unit The Partnership uses the two-class method to determine basic and diluted earnings per unit. The two-class method is an earnings allocation formula that determines the earnings for each class of equity ownership and participating security according to distributions declared and participation rights in undistributed earnings. The Partnership calculates basic and diluted net income attributable to Sunoco Logistics Partners L.P. ("net income attributable to SXL") per limited partner unit by dividing net income attributable to SXL, after deducting the amounts allocated to the general partner's interest and incentive distribution rights ("IDRs"), by the weighted average number of limited partner units and Class B units outstanding during the period. IDRs in a master limited partnership are treated as participating securities for the purpose of computing net income attributable to limited partner units. The general partner holds all of the IDRs. In addition, when earnings differ from cash distributions, undistributed or over distributed earnings are to be allocated to the general partner, limited partners and Class B unitholders based on the contractual terms of the partnership agreement. See Note 4 for additional information on the terms of the Class B units.
