Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Organization and Operations NGL Energy Partners LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware limited partnership . NGL Energy Holdings LLC serves as our general partner. At June 30, 2020 , our operations included three segments: • Our Crude Oil Logistics segment purchases crude oil from producers and marketers and transports it to refineries or for resale at pipeline injection stations, storage terminals, barge loading facilities, rail facilities, refineries, and other trade hubs, and provides storage, terminaling, and transportation services through its owned assets. Our activities in this segment are supported by certain long-term, fixed rate contracts which include minimum volume commitments on our pipelines. • Our Water Solutions segment transports, treats, recycles and disposes of produced and flowback water generated from crude oil and natural gas production. We also dispose of solids such as tank bottoms, drilling fluids and drilling muds and perform other ancillary services such as truck and frac tank washouts. As part of processing water, we are able to aggregate recovered crude oil, also known as skim oil, that was contained in the water and sell the crude oil. We also sell brackish non-potable water to our producer customers to be used in their crude oil exploration and production activities. Our activities in this segment are underpinned by long-term, fixed fee contracts and acreage dedications, some of which contain minimum volume commitments, with leading oil and gas companies including large, investment grade producer customers. • Our Liquids and Refined Products segment conducts marketing operations for natural gas liquids, refined petroleum products and biodiesel to a broad range of commercial, retail and industrial customers across the United States and Canada. These operations are conducted through our company-owned terminals, other third party storage and terminal facilities, common carrier pipelines and our extensive fleet of leased railcars. We also provide natural gas liquids and refined product terminaling and storage services at our salt dome storage facility joint venture in Utah and marine exports through our facility located in Chesapeake, Virginia. We employ a number of contractual and hedging strategies to minimize commodity exposure and maximize earnings stability of this segment.

Significant Accounting Policies

Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and account balances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, and expenses related to this pipeline in our unaudited condensed consolidated financial statements. Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim consolidated financial information in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the unaudited condensed consolidated financial statements exclude certain information and notes required by GAAP for complete annual consolidated financial statements. However, we believe that the disclosures made are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements include all adjustments that we consider necessary for a fair presentation of our consolidated financial position, results of operations and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed in this Quarterly Report. The unaudited condensed consolidated balance sheet at March 31, 2020 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2020 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on June 1, 2020. These interim unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report. Due to the seasonal nature of certain of our operations and other factors, the results of operations for interim periods are not necessarily indicative of the results of operations to be expected for future periods or for the full fiscal year ending March 31, 2021 . Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amount of assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periods presented. Critical estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the fair value of assets and liabilities acquired in acquisitions, the fair value of derivative instruments, the collectibility of accounts and notes receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation, accruals for environmental matters and estimating certain revenues. Although we believe these estimates are reasonable, actual results could differ from those estimates. Significant Accounting Policies Our significant accounting policies are consistent with those disclosed in Note 2 of our audited consolidated financial statements included in our Annual Report. Income Taxes We qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reports his or her share of our income or loss on his or her individual tax return. The aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined, as we do not have access to information regarding each partner’s basis in the Partnership. We have a deferred tax liability of $55.6 million and $56.4 million at June 30, 2020 and March 31, 2020 , respectively, as a result of acquiring corporations in connection with certain of our acquisitions, which is included within other noncurrent liabilities in our unaudited condensed consolidated balance sheet. The deferred tax liability is the tax effected cumulative temporary difference between the GAAP basis and tax basis of the acquired assets within the corporation. For GAAP purposes, certain of the acquired assets will be depreciated and amortized over time which will lower the GAAP basis. The deferred tax benefit recorded during the three months ended June 30, 2020 was $0.8 million with an effective tax rate of 23.5% . The deferred tax benefit recorded during the three months ended June 30, 2019 was $1.0 million with an effective tax rate of 24.6% . We evaluate uncertain tax positions for recognition and measurement in the unaudited condensed consolidated financial statements. To recognize a tax position, we determine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, based on the technical merits of the position. A tax position that meets the more likely than not threshold is measured to determine the amount of benefit to be recognized in the unaudited condensed consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2020 or March 31, 2020 . Inventories Our inventories are valued at the lower of cost or net realizable value, with cost determined using either the weighted-average cost or the first in, first out (FIFO) methods, including the cost of transportation and storage, and with net realizable value defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. In performing this analysis, we consider fixed-price forward commitments.

In addition, the amount at March 31, 2020 represents the noncurrent portion of a loan receivable associated with our interest in the construction of a natural gas liquids loading/unloading facility (the “Facility”) that is utilized by a third party. The third party filed for Chapter 11 bankruptcy in July 2019. For a further discussion, see Note 17.

Accrued Expenses and Other Payables Accrued expenses and other payables consist of the following at the dates indicated: June 30, 2020 March 31, 2020 (in thousands) Accrued compensation and benefits $ 26,646 $ 29,990 Excise and other tax liabilities 9,549 9,941 Derivative liabilities 3,469 17,777 Accrued interest 24,106 39,803 Product exchange liabilities 2,749 1,687 Contingent consideration liability (1) 36,169 102,419 Other 40,148 30,445 Total $ 142,836 $ 232,062 (1) Decrease is due to the monthly installment payments made during the three months ended June 30, 2020 related to our acquisition of certain assets of Mesquite Disposals Unlimited, LLC (“Mesquite”). We have made two monthly payments subsequent to June 30, 2020, and per the agreement, we currently have four remaining monthly payments. Reclassifications We have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscal year. These reclassifications did not impact previously reported amounts of assets, liabilities, equity, net income, or cash flows. Recent Accounting Pronouncements In March 2020, the SEC issued “Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities”, which amends the disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered in Rule 3-10 of Regulation S-X. The amendment simplifies the disclosure requirements and permits the amended disclosures to be provided outside the footnotes in audited annual or unaudited interim consolidated financial statements in all filings. The guidance is effective for the Partnership for fiscal periods ending after January 4, 2021, although early adoption is permitted. We adopted this guidance effective April 1, 2020 and elected to include the required summarized financial information in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity, Sources of Capital and Capital Resource Activities – Guarantor Summarized Financial Information .” In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected, which would include trade accounts receivable. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. We adopted ASU No. 2016-13 on April 1, 2020, using the modified retrospective approach with a cumulative effect adjustment of $1.1 million to opening equity at the beginning of the period of adoption. See Note 16 for a further discussion of the impact of the adoption of this ASU on our unaudited condensed consolidated financial statements.

The Credit Agreement provides up to $1.915 billion in aggregate commitments and consists of a revolving credit facility to fund working capital needs (“Working Capital Facility”), and another to fund acquisitions and expansion projects (“Expansion Capital Facility”). On April 27, 2020, we amended our Credit Agreement to reallocate availability between the two revolving credit facilities. We reduced the capacity of the Working Capital Facility to $350.0 million and increased the Expansion Capital Facility to $1.565 billion (the “Expansion Capital Facility,” and together with the Working Capital Facility, the “Revolving Credit Facility”). We had letters of credit of $85.2 million on the Working Capital Facility at June 30, 2020 . The capacity under the Working Capital Facility may be limited by a “borrowing base” (as defined in the Credit Agreement) which is calculated based on the value of certain working capital items at any point in time. The commitments under the Credit Agreement expire on October 5, 2021. At June 30, 2020 , the borrowings under the Credit Agreement had a weighted average interest rate of 2.74% , calculated as the weighted average LIBOR rate of 0.19% plus a margin of 2.50% for LIBOR borrowings and the prime rate of 3.25% plus a margin of 1.50% on alternate base rate borrowings. At June 30, 2020 , the interest rate in effect on letters of credit was 2.50% . Commitment fees are charged at a rate ranging from 0.375% to 0.50% on any unused capacity. The Credit Agreement specifies that our senior secured leverage ratio cannot be more than 3.50 to 1 , that our interest coverage ratio cannot be less than 2.50 to 1 and the total leverage indebtedness ratio cannot be more than 5.50 to 1 at any quarter end. At June 30, 2020 , our senior secured leverage ratio was approximately 3.06 to 1 , our interest coverage ratio was approximately 3.47 to 1 , and our total leverage indebtedness ratio was approximately 5.36 to 1. We were in compliance with the covenants under the Credit Agreement at June 30, 2020 .

Compliance At June 30, 2020 , we were in compliance with the covenants under the indentures for all of the Senior Unsecured Notes. Term Credit Agreement On June 3, 2020, we entered into a new $250.0 million term credit agreement (the “Term Credit Agreement”) with certain funds and accounts managed by affiliates of Apollo Global Management, Inc. to refinance the existing Bridge Term Credit Agreement (as defined herein). The commitments under the Term Credit Agreement expire on June 3, 2023 and are callable by us after two years at par. We are subject to prepayments of principal if we enter into certain transactions to sell assets, issue equity or obtain new borrowings. The obligations under the Term Credit Agreement are guaranteed by the Partnership and certain of NGL Energy Operating LLC’s (“Borrower”) wholly-owned subsidiaries, and are secured by substantially all of the assets of the Borrower, the Partnership and the other subsidiary guarantors subject to certain customary exclusions. All borrowings under the Term Credit Agreement bear interest at LIBOR (based on the higher of one-month or three-month LIBOR), subject to a 1.50% LIBOR floor, plus 8.00% . At June 30, 2020 , the borrowings under the Term Credit Agreement had an interest rate of 9.50% (as of June 30, 2020 the reference LIBOR rate was below the LIBOR floor of 1.50% ). The Term Credit Agreement contains various customary representations, warranties and covenants by the Partnership and its subsidiaries, including, without limitation, (i) financial covenants limiting leverage, including senior secured leverage and total leverage, and requiring a minimum interest coverage, (ii) negative covenants limiting indebtedness, liens, investments, equity distributions, dispositions and fundamental changes and involving the Partnership or its subsidiaries and (iii) affirmative covenants requiring, among other things, reporting of financial information and material events and covenants to maintain existence and pay taxes, in each case substantially consistent with the Borrower’s existing Revolving Credit Facility. The Term Credit Agreement specifies that our senior secured leverage ratio cannot be more than 3.50 to 1 , that our interest coverage ratio cannot be less than 2.50 to 1 and the total leverage indebtedness ratio cannot be more than 5.75 to 1 for the four fiscal quarters of the fiscal year ending March 31, 2021 . As of June 30, 2021 and through June 3, 2023, the maximum total leverage indebtedness ratio will be 5.50 to 1 . At June 30, 2020 , our senior secured leverage ratio was approximately 3.06 to 1 , our interest coverage ratio was approximately 3.47 to 1 , and our total leverage indebtedness ratio was approximately 5.36 to 1 . At June 30, 2020 , we were in compliance with the covenants under the Term Credit Agreement. Bridge Term Credit Agreement On July 2, 2019, we entered into a bridge term credit agreement (the “Bridge Term Credit Agreement”) with Toronto Dominion (Texas) LLC for a $250.0 million term loan facility. Toronto Dominion (Texas) LLC and certain of its affiliates are also lenders under our Credit Agreement. On June 3, 2020, we used the proceeds from the Term Credit Agreement to pay off the outstanding balance of the Bridge Term Credit Agreement. We wrote off $2.2 million of debt issuance costs to gain on early extinguishment of liabilities, net within our unaudited condensed consolidated statement of operations. Sawtooth Credit Agreement On November 27, 2019, Sawtooth Caverns LLC (“Sawtooth”), a joint venture in which we own approximately a 71.5% interest, entered into a credit agreement with Zions Bancorporation (doing business as “Amegy Bank”). The Sawtooth credit agreement has a capacity of $20.0 million . The commitments under the Sawtooth credit agreement expire on November 27, 2022. At June 30, 2020 , no amounts had been borrowed under the Sawtooth credit agreement. Commitment fees are charged at a rate of 0.50% on any unused capacity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Contingencies In August 2015, LCT Capital, LLC (“LCT”) filed a lawsuit against NGL Energy Holdings LLC (the “GP”) and the Partnership seeking payment for investment banking services relating to the purchase of TransMontaigne Inc. and related assets in July 2014. After pre-trial rulings, LCT was limited to pursuing claims of (i) quantum meruit (the value of the services rendered by LCT) and (ii) fraudulent misrepresentation against the defendants. Following a jury trial conducted in Delaware state court from July 23, 2018 through August 1, 2018, the jury returned a verdict consisting of an award of $4.0 million for quantum meruit and $29.0 million for fraudulent misrepresentation, subject to statutory interest. The GP and the Partnership contend that the jury verdict, at least in respect of fraudulent misrepresentation, is not supportable by either controlling law or the evidentiary record. On December 5, 2019, in response to the defendants’ post-trial motion, the Court issued an Order overturning the jury’s damages award and ordering the case to be set for a damages-only trial. Both parties filed applications with the trial court asking the trial court to certify the December 5th Order for interlocutory, immediate review by the Appellate Court. On December 23, 2019, the trial court issued an Order certifying for immediate review by the appellate court the issue of whether the types of damages awarded by the jury are legally supportable since it was also determined by the Court that there was no contract between the parties. On January 7, 2020, the Supreme Court of Delaware entered an Order expanding the issues to be reviewed on appeal to include the additional issues raised by the NGL parties’ application - namely, whether the December 5th Order correctly set aside the jury’s $4.0 million quantum meruit award, whether certain jury instructions were correct and whether the evidence presented at trial supported the claims asserted by LCT. The Supreme Court consolidated the appeal proceedings for judicial efficiency and set a briefing cycle for the parties whereby the appeal-related briefs and materials were fully submitted by both parties on August 10, 2020. It is our position that the awards, even if they each stand, are not cumulative. Any allocation of the ultimate verdict award between the GP and the Partnership will be made by the board of directors of our general partner once all information is available to it and after the post-trial and any appellate process has concluded and the verdict is final as a matter of law. Because the Partnership is a named defendant in the lawsuit, and any judgment ultimately awarded would be joint and several with the GP, we have determined that it is probable that the Partnership could be liable for a portion of this judgment. At this time, we believe the amount that could be allocated to the Partnership would not be material as it is estimated to be less than $4.0 million . As of June 30, 2020 , we have accrued $2.5 million related to this matter. We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the opinion of our management, the ultimate resolution of these claims, legal actions, and complaints, after consideration of amounts accrued, insurance coverage, and other arrangements, is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our liabilities may change materially as circumstances develop. Environmental Matters At June 30, 2020 , we have an environmental liability, measured on an undiscounted basis, of $1.9 million , which is recorded within accrued expenses and other payables in our unaudited condensed consolidated balance sheet. Our operations are subject to extensive federal, state, and local environmental laws and regulations. Although we believe our operations are in substantial compliance with applicable environmental laws and regulations, risks of additional costs and liabilities are inherent in our business, and there can be no assurance that we will not incur significant costs. Moreover, it is possible that other developments, such as increasingly stringent environmental laws, regulations and enforcement policies thereunder, and claims for damages to property or persons resulting from the operations, could result in substantial costs. Accordingly, we have adopted policies, practices, and procedures in the areas of pollution control, product safety, occupational health, and the handling, storage, use, and disposal of hazardous materials designed to prevent material environmental or other damage, and to limit the financial liability that could result from such events. However, some risk of environmental or other damage is inherent in our business. Asset Retirement Obligations We have contractual and regulatory obligations at certain facilities for which we have to perform remediation, dismantlement, or removal activities when the assets are retired. Our liability for asset retirement obligations is discounted to present value. To calculate the liability, we make estimates and assumptions about the retirement cost and the timing of retirement. Changes in our assumptions and estimates may occur as a result of the passage of time and the occurrence of future events. The following table summarizes changes in our asset retirement obligation, which is reported within other noncurrent liabilities in our unaudited condensed consolidated balance sheets (in thousands): Balance at March 31, 2020 $ 18,416 Liabilities incurred 830 Accretion expense 354 Balance at June 30, 2020 $ 19,600 In addition to the obligations described above, we may be obligated to remove facilities or perform other remediation upon retirement of certain other assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates are indeterminable. We will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable. Other Commitments We have noncancelable agreements for product storage, railcar spurs and real estate. The following table summarizes future minimum payments under these agreements at June 30, 2020 (in thousands): Fiscal Year Ending March 31, 2021 (nine months) $ 12,455 2022 11,838 2023 4,497 2024 197 2025 172 Thereafter 526 Total $ 29,685 As part of the acquisition of Hillstone, discussed in Note 4 , we assumed an obligation to pay a quarterly subsidy payment in the event that specified volumetric thresholds are not exceeded at a third-party facility. This agreement expires on December 31, 2022. For the three months ended June 30, 2020 , we recorded $0.7 million within operating expense in our unaudited condensed consolidated statement of operations. At June 30, 2020 , the range of potential payments we could be obligated to make pursuant to the subsidy agreement could be from $0.0 million to $8.1 million . Pipeline Capacity Agreements We have noncancelable agreements with crude oil pipeline operators, which guarantee us minimum monthly shipping capacity on the pipelines. As a result, we are required to pay the minimum shipping fees if actual shipments are less than our allotted capacity. Under certain agreements we have the ability to recover minimum shipping fees previously paid if our shipping volumes exceed the minimum monthly shipping commitment during each month remaining under the agreement, with some contracts containing provisions that allow us to continue shipping up to six months after the maturity date of the contract in order to recapture previously paid minimum shipping delinquency fees. We currently have an asset recorded in prepaid expenses and other current assets and in other noncurrent assets in our unaudited condensed consolidated balance sheet for minimum shipping fees paid in both the current and previous periods that are expected to be recovered in future periods by exceeding the minimum monthly volumes (see Note 2 ). The following table summarizes future minimum throughput payments under these agreements at June 30, 2020 (in thousands): Fiscal Year Ending March 31, 2021 (nine months) $ 26,509 2022 35,314 2023 35,314 2024 35,410 2025 30,897 Total $ 163,444 Construction Commitments At June 30, 2020 , we had construction commitments of $2.5 million . Sales and Purchase Contracts We have entered into product sales and purchase contracts for which we expect the parties to physically settle and deliver the inventory in future periods. At June 30, 2020 , we had the following commodity purchase commitments (in thousands): Crude Oil (1) Natural Gas Liquids Value Volume Value Volume Fixed-Price Commodity Purchase Commitments: 2021 (nine months) $ 48,972 1,347 $ 11,545 25,416 2022 — — 2,495 5,766 Total $ 48,972 1,347 $ 14,040 31,182 Index-Price Commodity Purchase Commitments: 2021 (nine months) $ 787,180 22,005 $ 456,844 937,433 2022 707,480 18,484 17,601 37,069 2023 643,062 15,702 — — 2024 602,350 14,359 — — 2025 436,785 10,220 — — Thereafter 17,426 390 — — Total $ 3,194,283 81,160 $ 474,445 974,502 (1) Our crude oil index-price purchase commitments exceed our crude oil index-price sales commitments (presented below) due primarily to our long-term purchase commitments for crude oil that we purchase and ship on the Grand Mesa Pipeline. As these purchase commitments are deliver-or-pay contracts, whereby our counterparty is required to pay us for any volumes not delivered, we have not entered into corresponding long-term sales contracts for volumes we may not receive. At June 30, 2020 , we had the following commodity sale commitments (in thousands): Crude Oil Natural Gas Liquids Value Volume Value Volume Fixed-Price Commodity Sale Commitments: 2021 (nine months) $ 49,667 1,347 $ 89,105 142,845 2022 — — 5,522 10,010 2023 — — 28 35 Total $ 49,667 1,347 $ 94,655 152,890 Index-Price Commodity Sale Commitments: 2021 (nine months) $ 545,789 13,865 $ 582,198 871,580 2022 193,108 4,745 11,309 18,682 2023 198,301 4,745 — — 2024 204,146 4,758 — — 2025 208,894 4,745 — — Thereafter 17,426 390 — — Total $ 1,367,664 33,248 $ 593,507 890,262 We account for the contracts shown in the tables above using the normal purchase and normal sale election. Under this accounting policy election, we do not record the physical contracts at fair value at each balance sheet date; instead, we record the purchase or sale at the contracted value once the delivery occurs. Contracts in the tables above may have offsetting derivative contracts (described in Note 11 ) or inventory positions (described in Note 2 ). Certain other forward purchase and sale contracts do not qualify for the normal purchase and normal sale election. These contracts are recorded at fair value in our unaudited condensed consolidated balance sheet and are not included in the tables above. These contracts are included in the derivative disclosures in Note 11 , and represent $3.5 million of our prepaid expenses and other current assets and $2.7 million of our accrued expenses and other payables at June 30, 2020 .

Equity

Equity [Abstract]
Equity	Equity Partnership Equity The Partnership’s equity consists of a 0.1% general partner interest and a 99.9% limited partner interest, which consists of common units. Our general partner has the right, but not the obligation, to contribute a proportionate amount of capital to us to maintain its 0.1% general partner interest. Our general partner is not required to guarantee or pay any of our debts and obligations. As of June 30, 2020 , we owned 8.69% of our general partner. Common Unit Repurchase Program On August 30, 2019, the board of directors of our general partner authorized a common unit repurchase program, under which we may repurchase up to $150.0 million of our outstanding common units through September 30, 2021 from time to time in the open market or in other privately negotiated transactions. We did not repurchase any units under this plan during the three months ended June 30, 2020 . Our Distributions The following table summarizes distributions declared on our common units during the last two quarters: Date Declared Record Date Payment Date Amount Per Unit Amount Paid/Payable Amount Paid/Payable (in thousands) (in thousands) April 27, 2020 May 7, 2020 May 15, 2020 $ 0.2000 $ 25,754 $ 26 July 23, 2020 August 6, 2020 August 14, 2020 $ 0.2000 $ 25,754 $ 26 Class B Preferred Units On June 13, 2017, we issued 8,400,000 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (“Class B Preferred Units”) representing limited partner interests at a price of $25.00 per unit for net proceeds of $202.7 million (net of the underwriters’ discount of $6.6 million and offering costs of $0.7 million ). On July 2, 2019, we issued 4,185,642 Class B Preferred Units to fund a portion of the purchase price for the Mesquite acquisition. The current distribution rate for the Class B Preferred Units is 9.00% per year of the $25.00 liquidation preference per unit (equal to $2.25 per unit per year). The following table summarizes distributions declared on our Class B Preferred Units during the last two quarters: Amount Paid to Class B Date Declared Record Date Payment Date Amount Per Unit Preferred Unitholders (in thousands) March 16, 2020 March 31, 2020 April 15, 2020 $ 0.5625 $ 7,079 June 15, 2020 June 30, 2020 July 15, 2020 $ 0.5625 $ 7,079 The distribution amount paid on July 15, 2020 is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at June 30, 2020 . Class C Preferred Units On April 2, 2019, we issued 1,800,000 of our 9.625% Class C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (“Class C Preferred Units”) representing limited partner interests at a price of $25.00 per unit for net proceeds of $42.9 million (net of the underwriters’ discount of $1.4 million and offering costs of $0.7 million ). The current distribution rate for the Class C Preferred Units is 9.625% per year of the $25.00 liquidation preference per unit (equal to $2.41 per unit per year). The following table summarizes distributions declared on our Class C Preferred Units during the last two quarters: Amount Paid to Class C Date Declared Record Date Payment Date Amount Per Unit Preferred Unitholders (in thousands) March 16, 2020 March 31, 2020 April 15, 2020 $ 0.6016 $ 1,083 June 15, 2020 June 30, 2020 July 15, 2020 $ 0.6016 $ 1,083 The distribution amount paid on July 15, 2020 is included in accrued expenses and other payables in our unaudited condensed consolidated balance sheet at June 30, 2020 . Class D Preferred Units On July 2, 2019, we completed a private placement of an aggregate of 400,000 preferred units (“Class D Preferred Units”) and warrants exercisable to purchase an aggregate of 17,000,000 common units for net proceeds of $385.4 million . On October 31, 2019, we completed a private placement of an aggregate of 200,000 Class D Preferred Units and warrants exercisable to purchase an aggregate of 8,500,000 common units for net proceeds of $194.7 million . As of June 30, 2020 , all warrants are still outstanding. The current distribution rate for the Class D Preferred Units is 9.00% per year per unit (equal to $90.00 per every $1,000 in unit value per year). The following table summarizes distributions declared on our Class D Preferred Units during the last two quarters: Amount Paid to Class D Date Declared Record Date Payment Date Amount Per Unit Preferred Unitholders (in thousands) April 27, 2020 May 7, 2020 May 15, 2020 $ 11.25 $ 6,868 July 23, 2020 August 6, 2020 August 14, 2020 $ 11.25 $ 6,946 The distributions paid in cash for the three months ended June 30, 2020 of $6.9 million represented 50% of the Class D Preferred Units distribution amount. In accordance with the terms of our Partnership Agreement, the value of each Class D Preferred Unit shall automatically increase by the non-cash accretion, which is approximately $6.9 million in the aggregate with respect to the distributions for the three months ended June 30, 2020 . Equity-Based Incentive Compensation Our general partner has adopted a long-term incentive plan (“LTIP”), which allows for the issuance of equity-based compensation. Our general partner has granted certain restricted units to employees and directors, which vest in tranches, subject to the continued service of the recipients through the vesting date (the “Service Awards”). The awards may also vest upon a change of control, at the discretion of the board of directors of our general partner. No distributions accrue to or are paid on the Service Awards during the vesting period. The following table summarizes the Service Award activity during the three months ended June 30, 2020 : Unvested Service Award units at March 31, 2020 1,371,425 Units granted 3,000 Units forfeited (10,500 ) Unvested Service Award units at June 30, 2020 1,363,925 The following table summarizes the scheduled vesting of our unvested Service Award units at June 30, 2020 : Fiscal Year Ending March 31, 2021 (nine months) 907,700 2022 456,225 Total 1,363,925 Service Awards are valued at the average of the high/low sales price as of the grant date less the present value of the expected distribution stream over the vesting period using a risk-free interest rate. The weighted-average grant price for June 30, 2020 was $4.54 . We record the expense for each Service Award on a straight-line basis over the requisite period for the entire award (that is, over the requisite service period of the last separately vesting portion of the award), ensuring that the amount of compensation cost recognized at any date at least equals the portion of the grant-date value of the award that is vested at that date. During the three months ended June 30, 2020 and 2019 , we recorded compensation expense related to Service Award units of $1.3 million and $2.8 million , respectively. The following table summarizes the estimated future expense we expect to record on the unvested Service Award units at June 30, 2020 (in thousands): Fiscal Year Ending March 31, 2021 (nine months) $ 3,602 2022 1,706 Total $ 5,308 As of June 30, 2020 , there are approximately 2.9 million common units remaining available for issuance under the LTIP.

These contracts are derivatives we have entered into as an economic hedge against the risk of mismatches between fixed and floating price physical obligations. During the three months ended June 30, 2020 and 2019 , we recorded a net loss of $27.4 million and a net gain of $5.6 million , respectively, from our commodity derivatives to revenues and cost of sales in our unaudited condensed consolidated statements of operations. The amounts for the three months ended June 30, 2020 and 2019 do not include net gains and losses related to Mid-Con (as defined herein), Gas Blending (as defined herein) and TPSL, as these amounts have been classified as discontinued operations within our unaudited condensed consolidated statement of operations (see Note 18 ). Credit Risk We have credit policies that we believe minimize our overall credit risk, including an evaluation of potential counterparties’ financial condition (including credit ratings), collateral requirements under certain circumstances, and the use of industry standard master netting agreements, which allow for offsetting counterparty receivable and payable balances for certain transactions. At June 30, 2020 , our primary counterparties were retailers, resellers, energy marketers, producers, refiners, and dealers. This concentration of counterparties may impact our overall exposure to credit risk, either positively or negatively, as the counterparties may be similarly affected by changes in economic, regulatory or other conditions. If a counterparty does not perform on a contract, we may not realize amounts that have been recorded in our unaudited condensed consolidated balance sheets and recognized in our net income. Interest Rate Risk The Revolving Credit Facility is variable-rate debt with interest rates that are generally indexed to bank prime or LIBOR interest rates. At June 30, 2020 , we had $1.7 billion of outstanding borrowings under the Revolving Credit Facility at a weighted average interest rate of 2.74% . The Term Credit Agreement is variable-rate debt with interest rates that are generally indexed to LIBOR interest rates. At June 30, 2020 , we had $250.0 million of outstanding borrowings under the Term Credit Agreement at an interest rate of 9.50% . Fair Value of Fixed-Rate Notes The following table provides fair value estimates of our fixed-rate notes at June 30, 2020 (in thousands): Senior Unsecured Notes: 2023 Notes $ 497,551 2025 Notes $ 292,972 2026 Notes $ 324,788 For the Senior Unsecured Notes, the fair value estimates were developed based on publicly traded quotes and would be classified as Level 2 in the fair value hierarchy.

Segment Reporting [Abstract]
Segments	Segments As a result of the sale of a large part of the assets that constituted the former Refined Products and Renewables reportable segment, the Chief Operating Decision Maker (CODM) decided during the fourth quarter of fiscal year 2020 that the remaining business within the former Refined Products and Renewables reportable segment would be aggregated with the former Liquids reportable segment and form the current Liquids and Refined Products reportable segment. Operating results for the reportable segments have been recast for the three months ended June 30, 2019 to reflect these changes. Our Crude Oil Logistics and Water Solutions reportable segments remain unchanged from what has been previously reported. The following table summarizes revenues related to our segments. Transactions between segments are recorded based on prices negotiated between the segments.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customer	Revenue from Contracts with Customers Effective April 1, 2018, we recognize revenue for services and products under revenue contracts as our obligations to either perform services or deliver or sell products under the contracts are satisfied. Our revenue contracts in scope under ASC 606 primarily have a single performance obligation and we do not receive material amounts of non-cash consideration. Our costs to obtain or fulfill our revenue contracts were not material as of June 30, 2020 . The majority of our revenue agreements are within scope under ASC 606 and the remainder of our revenue comes from contracts that are accounted for as derivatives under ASC 815 or that contain nonmonetary exchanges or leases and are in scope under Topics 845 and 842, respectively. See Note 12 for a detail of disaggregated revenue. Revenue from contracts accounted for as derivatives under ASC 815 within our Liquids and Refined Products segment includes $1.0 million of net gains related to changes in the mark-to-market value of these arrangements recorded during the three months ended June 30, 2020 . Remaining Performance Obligations Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements. The following table summarizes the amount and timing of revenue recognition for such contracts at June 30, 2020 (in thousands): Fiscal Year Ending March 31, 2021 (nine months) $ 181,644 2022 210,387 2023 204,131 2024 173,712 2025 147,638 Thereafter 164,437 Total (1) $ 1,081,949 (1) Amount includes revenue from a counterparty that filed for Chapter 11 bankruptcy in June 2020. See Note 17 for a further discussion.

Credit Loss [Abstract]
Allowance for Current Expected Credit Loss	Allowance for Current Expected Credit Loss (CECL) ASU 2016-13 requires that an allowance for expected credit losses be recognized for certain financial assets that reflects the current expected credit loss over the financial asset’s contractual life. The valuation allowance considers the risk of loss, even if remote, and considers past events, current conditions and reasonable and supportable forecasts. We are exposed to credit losses primarily through sale of products and services and notes receivable from third-parties. A counterparty’s ability to pay is assessed through a credit process that considers the payment terms, the counterparty’s established credit rating or our assessment of the counterparty’s credit worthiness and other risks. We can require prepayment or collateral to mitigate credit risks. We group our financial assets into pools of counterparties with similar risk characteristics for the purpose of determining the allowance for expected credit losses. Each reporting period, we assess whether a significant change in the risk of expected credit loss has occurred. Among the quantitative and qualitative factors considered in calculating our allowance for expected credit losses are historical financial data, including write-offs and allowances, current conditions, industry risk and current credit ratings. Financial assets will be written off in whole, or in part, when practical recovery efforts have been exhausted and no reasonable expectation of recovery exists. Subsequent recoveries of amounts previously written off are recorded as an increase to the allowance. We manage receivable pools using past due balances as a key credit quality indicator. The following table summarizes changes in our allowance for expected credit losses: Accounts Receivable - Trade Notes Receivable and Other (in thousands) Balance at March 31, 2020 $ 4,540 $ — Cumulative effect adjustment 433 680 Current period provision for expected credit losses (27 ) — Write-offs charged against the allowance (1,272 ) (222 ) Balance at June 30, 2020 $ 3,674 $ 458

Other Matters [Abstract]
Other Matters	Other Matters Third-party Loan Receivable As discussed previously in Note 2, we had an outstanding loan receivable of $26.7 million , including accrued interest, associated with our interest in the Facility that is utilized by a third party. Our loan receivable was secured by title to and a lien interest on the Facility. The third party filed a petition for bankruptcy under Chapter 11 of the bankruptcy code in July 2019, at which time we filed our Proof of Claim within the bankruptcy case. The Chapter 11 plan, as supplemented, was approved by the bankruptcy court in February 2020, pursuant to which we were expected to be paid a $26.7 million secured claim as an unimpaired creditor. After the approval of the supplemental plan, the third party attempted to negotiate with us to accept an amount less than the full amount of our claim or to take back the Facility in kind. In May 2020, we filed a motion with the bankruptcy court to compel the third party to pay us the full amount of the claim in accordance with the approved plan. The bankruptcy court ruled in May 2020 that the third party would need to either pay us the full amount of the claim or deliver the Facility to us at a destination of our reasonable choosing. On June 26, 2020, we settled our claim with the third party and agreed to receive $16.3 million , for which we released any and all claims and/or liens with respect to the Facility and transferred title of the Facility to the third party. For the remaining $10.4 million of the loan receivable, we have filed an unsecured claim within the bankruptcy. As of June 30, 2020 , we wrote-off approximately $9.4 million , the portion of the unsecured claimed we have deemed uncollectible, and this amount was recorded as a loss within loss (gain) on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. As of June 30, 2020, the remaining balance of $0.6 million , net of an allowance for an expected credit loss, is recorded within prepaid expenses and other current assets in our unaudited condensed consolidated balance sheet. Third-party Bankruptcy During the three months ended June 30, 2020, a third-party, who is a significant shipper on our crude oil pipeline, filed a petition for bankruptcy under Chapter 11 of the bankruptcy code. This third-party has transportation contracts pursuant to which it has committed to ship crude oil on our pipeline through October 2026. As part of the bankruptcy filing, the third-party has requested that the court authorize it to reject these transportation contracts, effective June 14, 2020. We dispute the third party’s ability to reject the transportation contracts and have, among other things, filed an objection within the bankruptcy and, currently, a hearing on this matter is set to take place on September 3, 2020. The third-party also has a water disposal contract with our Water Solutions segment whereby we dispose of its produced water for a fee. For this contract, because we are secured by statutory liens, we have requested that they pay us for those prepetition services under authority granted to them by the bankruptcy court. Pending receipt of that payment, we will be filing a secured claim in the bankruptcy case. On August 10, 2020, the third-party filed a motion with the bankruptcy court to also reject our water disposal contract and we have 14 days from the date of their filing in which to respond with our objection. Since the filing of the bankruptcy petition, the third-party has continued to utilize the services under both the transportation contracts and the water disposal contract and the third-party is current on all of its post filing date receivables.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations As previously disclosed, on September 30, 2019, we completed the sale of TransMontaigne Product Services, LLC (“TPSL”) to Trajectory Acquisition Company, LLC. On January 3, 2020, we completed the sale of our refined products business in the mid-continent region of the United States (“Mid-Con”) to a third-party. On March 30, 2020, we completed the sale of our gas blending business in the southeastern and eastern regions of the United States (“Gas Blending”) to another third-party. As the sale of each of these businesses represented strategic shifts, the results of operations and cash flows related to these businesses are classified as discontinued operations for all periods presented, and prior periods have been retrospectively adjusted in the unaudited condensed consolidated statement of operations and unaudited condensed consolidated statement of cash flows. The following table summarizes the results of operations from discontinued operations for the periods indicated: Three Months Ended June 30, 2020 2019 (in thousands) Revenues $ 16,198 $ 4,766,000 Cost of sales 16,311 4,763,537 Operating expenses 208 2,955 General and administrative expense — 21 Depreciation and amortization — 454 Loss on disposal or impairment of assets, net (1) 1,065 — Operating loss from discontinued operations (1,386 ) (967 ) Interest expense (100 ) (31 ) Other income, net — 65 Loss from discontinued operations before taxes (1,486 ) (933 ) Income tax expense — (10 ) Loss from discontinued operations, net of tax $ (1,486 ) $ (943 ) (1) Amount for the three months ended June 30, 2020 includes a loss of $1.0 million on the sale of Gas Blending and $0.1 million on the sale of TPSL . Continuing Involvement As of June 30, 2020 , we have commitments to sell up to 56.8 million gallons of propane, valued at $37.4 million (based on the contract price), to Superior Plus Corp. and DCC LPG, the purchasers of our former Retail Propane segment, through May 2021. During the three months ended June 30, 2020 , we received $0.6 million from DCC LPG for propane sold to them during the period.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include our accounts and those of our controlled subsidiaries. Intercompany transactions and account balances have been eliminated in consolidation. Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. We also own an undivided interest in a crude oil pipeline, and include our proportionate share of assets, liabilities, and expenses related to this pipeline in our unaudited condensed consolidated financial statements. Our unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim consolidated financial information in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, the unaudited condensed consolidated financial statements exclude certain information and notes required by GAAP for complete annual consolidated financial statements. However, we believe that the disclosures made are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements include all adjustments that we consider necessary for a fair presentation of our consolidated financial position, results of operations and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed in this Quarterly Report. The unaudited condensed consolidated balance sheet at March 31, 2020 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2020 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on June 1, 2020.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amount of assets and liabilities reported at the date of the consolidated financial statements and the amount of revenues and expenses reported during the periods presented. Critical estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the fair value of assets and liabilities acquired in acquisitions, the fair value of derivative instruments, the collectibility of accounts and notes receivable, the recoverability of inventories, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the impairment of long-lived assets and goodwill, the fair value of asset retirement obligations, the value of equity-based compensation, accruals for environmental matters and estimating certain revenues. Although we believe these estimates are reasonable, actual results could differ from those estimates.
Income Taxes	Income Taxes We qualify as a partnership for income tax purposes. As such, we generally do not pay United States federal income tax. Rather, each owner reports his or her share of our income or loss on his or her individual tax return. The aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined, as we do not have access to information regarding each partner’s basis in the Partnership. We have a deferred tax liability of $55.6 million and $56.4 million at June 30, 2020 and March 31, 2020 , respectively, as a result of acquiring corporations in connection with certain of our acquisitions, which is included within other noncurrent liabilities in our unaudited condensed consolidated balance sheet. The deferred tax liability is the tax effected cumulative temporary difference between the GAAP basis and tax basis of the acquired assets within the corporation. For GAAP purposes, certain of the acquired assets will be depreciated and amortized over time which will lower the GAAP basis. The deferred tax benefit recorded during the three months ended June 30, 2020 was $0.8 million with an effective tax rate of 23.5% . The deferred tax benefit recorded during the three months ended June 30, 2019 was $1.0 million with an effective tax rate of 24.6% . We evaluate uncertain tax positions for recognition and measurement in the unaudited condensed consolidated financial statements. To recognize a tax position, we determine whether it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation, based on the technical merits of the position. A tax position that meets the more likely than not threshold is measured to determine the amount of benefit to be recognized in the unaudited condensed consolidated financial statements. We had no material uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2020 or March 31, 2020 .
Inventories	Inventories
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities Investments we do not control, but can exercise significant influence over, are accounted for using the equity method of accounting. Investments in partnerships and limited liability companies, unless our investment is considered to be minor, and investments in unincorporated joint ventures are also accounted for using the equity method of accounting.
Reclassifications	Reclassifications We have reclassified certain prior period financial statement information to be consistent with the classification methods used in the current fiscal year. These reclassifications did not impact previously reported amounts of assets, liabilities, equity, net income, or cash flows.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the SEC issued “Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities”, which amends the disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered in Rule 3-10 of Regulation S-X. The amendment simplifies the disclosure requirements and permits the amended disclosures to be provided outside the footnotes in audited annual or unaudited interim consolidated financial statements in all filings. The guidance is effective for the Partnership for fiscal periods ending after January 4, 2021, although early adoption is permitted. We adopted this guidance effective April 1, 2020 and elected to include the required summarized financial information in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity, Sources of Capital and Capital Resource Activities – Guarantor Summarized Financial Information .” In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses.” The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected, which would include trade accounts receivable. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. We adopted ASU No. 2016-13 on April 1, 2020, using the modified retrospective approach with a cumulative effect adjustment of $1.1 million to opening equity at the beginning of the period of adoption. See Note 16 for a further discussion of the impact of the adoption of this ASU on our unaudited condensed consolidated financial statements.

Service Awards	Service Awards are valued at the average of the high/low sales price as of the grant date less the present value of the expected distribution stream over the vesting period using a risk-free interest rate. The weighted-average grant price for June 30, 2020 was $4.54 . We record the expense for each Service Award on a straight-line basis over the requisite period for the entire award (that is, over the requisite service period of the last separately vesting portion of the award), ensuring that the amount of compensation cost recognized at any date at least equals the portion of the grant-date value of the award that is vested at that date.
