Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Description of Business and Basis of Presentation	Organization, Description of Business and Basis of Presentation Organization Unless indicated otherwise, the terms “our,” “we,” “us” and similar language refer to Magellan Midstream Partners, L.P. together with its subsidiaries. Magellan Midstream Partners, L.P. is a Delaware limited partnership, and our common units are traded on the New York Stock Exchange under the ticker symbol “MMP.” Magellan GP, LLC, a wholly owned Delaware limited liability company, serves as our general partner. The board of directors of our general partner is referred to herein as our “board.” Description of Business We are principally engaged in the transportation, storage and distribution of refined petroleum products and crude oil. As of March 31, 2022, our asset portfolio, excluding assets associated with discontinued operations, consisted of: • our refined products segment, comprised of our approximately 9,800-mile refined petroleum products pipeline system with 54 terminals and two marine storage terminals (one of which is owned through a joint venture); and • our crude oil segment, comprised of approximately 2,200 miles of crude oil pipelines, a condensate splitter and 39 million barrels of aggregate storage capacity, of which approximately 29 million barrels are used for contract storage. Approximately 1,000 miles of these pipelines, the condensate splitter and 31 million barrels of this storage capacity (including 25 million barrels used for contract storage) are wholly-owned, with the remainder owned through joint ventures. The following terms are commonly used in our industry to describe products that we transport, store, distribute or otherwise handle through our petroleum pipelines and terminals: • refined products are the output from crude oil refineries that are primarily used as fuels by consumers. Refined products include gasoline, diesel fuel, aviation fuel, kerosene and heating oil. Diesel fuel, kerosene and heating oil are also referred to as distillates; • transmix is a mixture that forms when different refined products are transported in pipelines. Transmix is fractionated and blended into usable refined products; • LPGs are liquids produced as by-products of the crude oil refining process and in connection with natural gas production. LPGs include gas liquids such as butane, natural gasoline and propane; • blendstocks are products blended with refined products to change or enhance their characteristics such as increasing a gasoline’s octane or oxygen content. Blendstocks include alkylates and oxygenates; and • crude oil, which includes condensate, is a naturally occurring unrefined petroleum product recovered from underground that is used as feedstock by refineries, splitters and petrochemical facilities. We use the term petroleum products to describe any, or a combination, of the above-noted products. In addition, we handle, store and distribute renewable fuels, such as ethanol and biodiesel. Basis of Presentation In the opinion of management, our accompanying consolidated financial statements which are unaudited, except for the consolidated balance sheet as of December 31, 2021, which is derived from our audited financial statements, include all normal and recurring adjustments necessary to present fairly our financial position as of March 31, 2022, the results of operations for the three months ended March 31, 2021 and 2022 and cash flows for the three months ended March 31, 2021 and 2022. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full year ending December 31, 2022 for several reasons. Profits from our gas liquids blending activities are realized largely during the first and fourth quarters of each year. Additionally, gasoline demand, which drives transportation volumes and revenues on our refined products pipeline system, generally trends higher during the summer driving months. Further, the volatility of commodity prices impacts the profits from our commodity activities and the volume of petroleum products we transport on our pipelines. Pursuant to the rules and regulations of the Securities and Exchange Commission, the financial statements in this report have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. Discontinued Operations In June 2021, we entered into an agreement to sell our independent terminals network comprised of 26 refined petroleum products terminals with approximately six million barrels of storage located primarily in the southeastern U.S. to Buckeye Partners, L.P. (“Buckeye”). The sale is expected to close upon the receipt of required regulatory approval. The related results of operations, financial position and cash flows have been classified as discontinued operations for all periods presented (see Note 2 – Discontinued Operations and Assets Held for Sale for additional details). Unless indicated otherwise, the information in the Notes to Consolidated Financial Statements relates to continuing operations. Reclassifications Certain prior period amounts have been reclassified to conform with the current period’s presentation, including amounts related to our discontinued operations. Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities that exist at the date of our consolidated financial statements, as well as their impact on the reported amounts of revenue and expense during the reporting periods. Actual results could differ from those estimates. New Accounting Pronouncements We evaluate new Accounting Standards Codifications (“ASC”) and updates issued by the Financial Accounting Standards Board on an ongoing basis. There are no new accounting pronouncements that we anticipate will have a material impact on our financial statements.

Segment Reporting [Abstract]
Segment Disclosures	Segment Disclosures Our reportable segments are strategic business units that offer different products and services. Our segments are managed separately because each segment requires different marketing strategies and business knowledge. Management evaluates performance based on segment operating margin, which includes revenue from affiliates and third-party customers, intersegment transactions, operating expense, cost of product sales, other operating (income) expense and earnings of non-controlled entities. We believe that investors benefit from having access to the same financial measures used by management. Operating margin, which is presented in the following tables, is an important measure used by management to evaluate the economic performance of our core operations. Operating margin is not a GAAP measure, but the components of operating margin are computed using amounts that are determined in accordance with GAAP. A reconciliation of operating margin to operating profit, which is its nearest comparable GAAP financial measure, is included in the tables below. Operating profit includes depreciation, amortization and impairment expense and general and administrative (“G&A”) expense that management does not consider when evaluating the core profitability of our separate operating segments.

At March 31, 2022, the total borrowing capacity under our revolving credit facility maturing in May 2024 was $1.0 billion. Any borrowings outstanding under this facility are classified as long-term debt on our consolidated balance sheets. Borrowings under the facility are unsecured and bear interest at LIBOR plus a spread ranging from 0.875% to 1.500% based on our credit ratings. Additionally, an unused commitment fee is assessed at a rate between 0.075% and 0.200% depending on our credit ratings. The unused commitment fee was 0.125% at March 31, 2022. Borrowings under this facility may be used for general purposes, including capital expenditures. As of December 31, 2021 and March 31, 2022, there were no borrowings outstanding under this facility and $3.5 million was obligated for letters of credit. Amounts obligated for letters of credit are not reflected as debt on our consolidated balance sheets, but decrease our borrowing capacity under this facility. Our revolving credit facility requires us to maintain a specified ratio of consolidated debt to EBITDA (as defined in the credit agreement) of no greater than 5.0 to 1.0. In addition, the revolving credit facility and the indentures under which our senior notes were issued contain covenants that limit our ability to, among other things, incur indebtedness secured by certain liens or encumber our assets, engage in certain sale-leaseback transactions and consolidate, merge or dispose of all or substantially all of our assets. We were in compliance with these covenants as of and during the three months ended March 31, 2022. Commercial Paper Program. We have a commercial paper program under which we may issue commercial paper notes in an amount up to the available capacity under our $1.0 billion revolving credit facility. The maturities of the commercial paper notes vary, but may not exceed 397 days from the date of issuance. Because the commercial paper we can issue is limited to amounts available under our revolving credit facility, amounts

Share-based Payment Arrangement [Abstract]
Long-Term Incentive Plan	Long-Term Incentive Plan The compensation committee of our board administers our long-term incentive plan (“LTIP”) covering certain of our employees and the independent directors of our board. The LTIP primarily consists of phantom units and permits the grant of awards covering an aggregate payout of 13.7 million of our common units. The estimated units remaining available under the LTIP at March 31, 2022 totaled approximately 1.8 million. Equity-based incentive compensation expense for the three months ended March 31, 2021 and 2022, primarily recorded as G&A expense on our consolidated statements of income, was as follows (in millions): Three Months Ended March 31, 2021 2022 Performance-based awards $ 2.2 $ 8.0 Time-based awards 2.5 6.4 Total $ 4.7 $ 14.4 On February 9, 2022, 622,986 unit awards were granted pursuant to our LTIP. These awards included both performance-based and time-based awards and have a three-year vesting period that will end on December 31, 2024. Basic and Diluted Net Income Per Common Unit The difference between our actual common units outstanding and our weighted average number of common units outstanding used to calculate net income per common unit is due to the impact of: (i) the phantom units issued to our independent directors, (ii) unit awards granted to retirees or employees of retirement age and (iii) the weighted average effect of units actually issued or repurchased during a period. The difference between the weighted average number of common units outstanding used for basic and diluted net income per unit calculations on our consolidated statements of income is primarily the dilutive effect of phantom unit awards granted pursuant to our long-term incentive plan, which have not yet vested in periods where contingent performance metrics have been met.

We have the right to offset the combined fair values of our open derivatives contracts against our margin deposits under a master netting arrangement for each counterparty; however, we have elected to present the combined fair values of our open derivatives contracts separately from the related margin deposits on our consolidated balance sheets. Additionally, we have the right to offset the fair values of our derivatives contracts together for each counterparty, which we have elected to do, and we report the combined net balances on our consolidated balance sheets. A schedule of the derivative amounts we have offset and the deposit amounts we could offset under master netting arrangements are provided below as of December 31, 2021 and March 31, 2022 (in millions): Description Gross Amounts of Recognized Liabilities Gross Amounts of Assets Offset in the Consolidated Balance Sheets Net Amounts of Liabilities Presented in the Consolidated Balance Sheets Margin Deposit Amounts Not Offset in the Consolidated Balance Sheets Net Asset Amount (1) As of December 31, 2021 $ (22.3) $ 5.1 $ (17.2) $ 46.3 $ 29.1 As of March 31, 2022 $ (59.2) $ 11.8 $ (47.4) $ 130.8 $ 83.4 (1) Amount represents the maximum loss we would incur if all of our counterparties failed to perform on their derivative contracts. Basis Derivative Agreement During 2019, we entered into a basis derivative agreement with a joint venture co-owner’s affiliate, and, contemporaneously, that affiliate entered into an intrastate transportation services agreement with the joint venture. Settlements under the basis derivative agreement are determined based on the basis differential of crude oil prices at different market locations and a notional volume of 30,000 barrels per day. As a result, we account for this agreement as a derivative and recognize the changes in fair value based on forward price curves for crude oil in West Texas and the Houston Gulf Coast in other operating income (expense) in our consolidated statements of income. The liability for this agreement at December 31, 2021 was $1.5 million.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Methods and Assumptions - Financial Assets and Liabilities We used the following methods and assumptions in estimating fair value of our financial assets and liabilities: • Commodity derivatives contracts . These include exchange-traded and over-the-counter derivative contracts related to petroleum products. These contracts are carried at fair value on our consolidated balance sheets. The exchange-traded contracts are valued based on quoted prices in active markets, while the over-the-counter contracts are valued based on observable market data inputs including published commodity pricing data. See Note 11 – Derivative Financial Instruments for further disclosures regarding these contracts. • Basis derivative agreement. During 2019, we entered into a basis derivative agreement with a joint venture co-owner’s affiliate, and, contemporaneously, that affiliate entered into an intrastate transportation services agreement with the joint venture. Settlements under the basis derivative agreement are determined based on the basis differential of crude oil prices at different market locations and a notional volume of 30,000 barrels per day (see Note 11 - Derivative Financial Instruments for further disclosures regarding this agreement). The fair value of this derivative was calculated based on observable market data inputs, including published commodity pricing data and market interest rates. The key inputs in the fair value calculation include the forward price curves for crude oil, the implied forward correlation in crude oil prices between West Texas and the Houston Gulf Coast, and the implied forward volatility for crude oil futures contracts. • Long-term receivables. These include payments receivable under a sales-type leasing arrangement and payments due to us for environmental liability insurance. These receivables were recorded at fair value on our consolidated balance sheets, using then-current market rates to estimate the present value of future cash flows. • Contractual obligations. At March 31, 2022, these primarily included a long-term contractual obligation we entered into in connection with the 2020 sale of three marine terminals to a subsidiary of Buckeye. This obligation requires us to perform certain environmental remediation work on Buckeye’s behalf at the New Haven, Connecticut terminal. This contractual obligation was recorded at fair value on our consolidated balance sheets upon initial recognition and was calculated using our best estimate of potential outcome scenarios to determine our liability for the remediation costs required in this agreement. • Debt. The fair value of our publicly traded notes was based on the prices of those notes at December 31, 2021 and March 31, 2022; however, where recent observable market trades were not available, prices were determined using adjustments to the last traded value for that debt issuance or by adjustments to the prices of similar debt instruments of peer entities that are actively traded. The carrying amount of borrowings, if any, under our revolving credit facility and our commercial paper program approximates fair value due to the frequent repricing of these obligations. Fair Value Measurements - Financial Assets and Liabilities The following tables summarize the carrying amounts, fair values and fair value measurements recorded or disclosed as of December 31, 2021 and March 31, 2022 based on the three levels established by ASC 820, Fair Value Measurements and Disclosures (in millions): Assets (Liabilities) Fair Value Measurements as of Carrying Amount Fair Value Quoted Prices in Active Markets Significant Significant Commodity derivatives contracts $ (17.2) $ (17.2) $ (18.6) $ 1.4 $ — Basis derivative agreement $ (1.5) $ (1.5) $ — $ (1.5) Long-term receivables $ 10.1 $ 10.1 $ — $ — $ 10.1 Contractual obligations $ (9.8) $ (9.8) $ — $ — $ (9.8) Debt $ (5,088.8) $ (5,711.5) $ — $ (5,711.5) $ — Assets (Liabilities) Fair Value Measurements as of Carrying Amount Fair Value Quoted Prices in Active Markets Significant Significant Commodity derivatives contracts $ (47.4) $ (47.4) $ (50.5) $ 3.1 $ — Long-term receivables $ 9.8 $ 9.8 $ — $ — $ 9.8 Contractual obligations $ (9.6) $ (9.6) $ — $ — $ (9.6) Debt $ (5,317.2) $ (5,409.5) $ — $ (5,409.5) $ —

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Corpus Christi Terminal Proceeding. On April 11, 2022, the State of Texas, through its Attorney General on behalf of the Texas Commission on Environmental Quality (“TCEQ”), brought an action for alleged violations of the Texas Clean Air Act in connection with a December 2020 fire at our Corpus Christi, Texas terminal. The TCEQ is seeking statutory civil penalties and statutory attorney’s fees over $0.3 million but not more than $1.0 million. While the outcome cannot be predicted with certainty, we believe the ultimate resolution of this matter will not have a material adverse effect on our business. Hurricane Harvey Enforcement Proceeding. In July 2018, we received a Notice of Enforcement letter from the TCEQ alleging two air emission violations at our Galena Park, Texas terminal that occurred during Hurricane Harvey in third quarter 2017. The penalties associated with these alleged violations are expected to be approximately $0.4 million. While the outcome cannot be predicted with certainty, we believe the ultimate resolution of this matter will not have a material adverse effect on our business. Butane Blending Patent Infringement Proceeding. In October 2017, Sunoco Partners Marketing & Terminals L.P. (“Sunoco”) brought an action for patent infringement in the U.S. District Court for the District of Delaware alleging Magellan Midstream Partners, L.P. (“Magellan”) and Powder Springs Logistics, LLC (“Powder Springs”) were infringing patents relating to butane blending at the Powder Springs facility located in Powder Springs, Georgia. Sunoco subsequently submitted pleadings alleging that Magellan was also infringing various patents related to butane blending at eight Magellan facilities, in addition to Powder Springs. Sunoco sought monetary damages, attorneys’ fees and a permanent injunction enjoining Powder Springs from infringing the subject patents. A jury trial concluded on December 6, 2021, at which the jury found Magellan willfully infringed the three patents in suit and awarded damages of approximately $9.4 million against Magellan relating to the eight Magellan facilities at issue. The jury further found that Powder Springs willfully infringed the one patent at issue relating to the Powder Springs facility and awarded approximately $2.8 million against Magellan and Powder Springs relating to that facility. Sunoco requested that the court enhance the damages award based upon the jury’s finding of willfulness, and that the court award additional damages and pre- and post-judgment interest. Magellan and Powder Springs have filed post-trial pleadings opposing Sunoco’s request for enhanced damages and challenging the findings of liability and willfulness. The final determination of the trial court is subject to potential future appeals by either or both parties to the litigation. The amounts we have accrued in relation to the claims are immaterial, and although it is not possible to predict the ultimate outcome, we believe the final resolution of this matter will not have a material adverse effect on our business. Environmental Liabilities Liabilities recognized for estimated environmental costs were $9.8 million and $9.7 million at December 31, 2021 and March 31, 2022, respectively. We have classified environmental liabilities as current or noncurrent based on management’s estimates regarding the timing of actual payments. Environmental expenses recognized as a result of changes in our environmental liabilities are included in operating expenses on our consolidated statements of income. Environmental expenses were $1.1 million and $0.9 million for the three months ended March 31, 2021 and 2022, respectively. Other In first quarter 2020, we entered into a long-term contractual obligation in connection with the sale of three marine terminals to Buckeye. This obligation requires us to perform certain environmental remediation work on Buckeye’s behalf at the New Haven, Connecticut terminal. At December 31, 2021, our balance sheet included a current liability of $0.5 million and a noncurrent liability of $8.9 million, and as of March 31, 2022, our balance sheet included a current liability of $0.3 million and a noncurrent liability of $8.9 million, reflecting the fair values of these obligations. We have entered into an agreement to guarantee our 50% pro rata share, up to $25.0 million, of contractual obligations under the Powder Springs’ credit facility. As of March 31, 2022, our consolidated balance sheets reflected a $0.4 million other current liability and a corresponding increase in our investment in non-controlled entities on our consolidated balance sheets to reflect the fair value of this guarantee.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of management, our accompanying consolidated financial statements which are unaudited, except for the consolidated balance sheet as of December 31, 2021, which is derived from our audited financial statements, include all normal and recurring adjustments necessary to present fairly our financial position as of March 31, 2022, the results of operations for the three months ended March 31, 2021 and 2022 and cash flows for the three months ended March 31, 2021 and 2022. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full year ending December 31, 2022 for several reasons. Profits from our gas liquids blending activities are realized largely during the first and fourth quarters of each year. Additionally, gasoline demand, which drives transportation volumes and revenues on our refined products pipeline system, generally trends higher during the summer driving months. Further, the volatility of commodity prices impacts the profits from our commodity activities and the volume of petroleum products we transport on our pipelines. Pursuant to the rules and regulations of the Securities and Exchange Commission, the financial statements in this report have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021. Discontinued Operations In June 2021, we entered into an agreement to sell our independent terminals network comprised of 26 refined petroleum products terminals with approximately six million barrels of storage located primarily in the southeastern U.S. to Buckeye Partners, L.P. (“Buckeye”). The sale is expected to close upon the receipt of required regulatory approval. The related results of operations, financial position and cash flows have been classified as discontinued operations for all periods presented (see Note 2 – Discontinued Operations and Assets Held for Sale for additional details). Unless indicated otherwise, the information in the Notes to Consolidated Financial Statements relates to continuing operations.
Use of Estimates	Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities that exist at the date of our consolidated financial statements, as well as their impact on the reported amounts of revenue and expense during the reporting periods. Actual results could differ from those estimates.
New Accounting Pronouncements	New Accounting Pronouncements We evaluate new Accounting Standards Codifications (“ASC”) and updates issued by the Financial Accounting Standards Board on an ongoing basis. There are no new accounting pronouncements that we anticipate will have a material impact on our financial statements.
