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 (“GP”). At June 30, 2022, our operations included three segments: • Our Water Solutions segment transports, treats, recycles and disposes of produced and flowback water generated from crude oil and natural gas production. We also sell produced water for reuse and recycle and brackish non-potable water to our producer customers to be used in their crude oil exploration and production activities. As part of processing water, we aggregate and sell recovered crude oil, also known as skim oil. 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. 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 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 owned and leased pipelines. • Our Liquids Logistics segment conducts supply 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 24 owned terminals, third-party storage and terminal facilities, nine common carrier pipelines and a fleet of leased railcars. We also provide services for marine exports of butane through our facility located in Chesapeake, Virginia. Our propane pipeline in Michigan was completed on August 8, 2022.

Significant Accounting Policies

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, 2022 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2022 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on June 6, 2022. 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, 2023. 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 accounting estimates we make in the preparation of our unaudited condensed consolidated financial statements include, among others, determining the impairment of goodwill and long-lived assets, useful lives and recoverability of property, plant and equipment and amortizable intangible assets, the fair value of derivative instruments, estimating certain revenues, the fair value of asset retirement obligations, the fair value of assets and liabilities acquired in acquisitions, the recoverability of inventories, the collectibility of accounts and notes receivable and accruals for environmental matters. 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 $42.9 million and $43.5 million at June 30, 2022 and March 31, 2022, 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 sheets. 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, 2022 was $0.7 million with an effective tax rate of 24.1%. The deferred tax benefit recorded during the three months ended June 30, 2021 was $1.1 million with an effective tax rate of 23.1%. 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 uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2022 or March 31, 2022. 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. Inventories consist of the following at the dates indicated: June 30, 2022 March 31, 2022 (in thousands) Crude oil $ 91,345 $ 135,485 Propane 81,101 43,971 Butane 71,929 33,144 Biodiesel 37,550 20,474 Diesel 3,801 3,504 Ethanol 3,698 3,503 Other 11,874 11,196 Total $ 301,298 $ 251,277 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. Our investments in unconsolidated entities consist of the following at the dates indicated: Entity Segment Ownership Interest June 30, 2022 March 31, 2022 (in thousands) Water services and land company Water Solutions 50% $ 16,264 $ 15,714 Water services and land company Water Solutions 10% 2,898 2,863 Water services and land company Water Solutions 50% 2,381 2,210 Aircraft company (1) Corporate and Other 50% 473 538 Water services company Water Solutions 50% 409 409 Natural gas liquids terminal company Liquids Logistics 50% 146 163 Total $ 22,571 $ 21,897 (1) This is an investment with a related party. Other Noncurrent Assets Other noncurrent assets consist of the following at the dates indicated: June 30, 2022 March 31, 2022 (in thousands) Linefill (1) $ 28,065 $ 28,065 Minimum shipping fees - pipeline commitments (2) 7,831 8,899 Loan receivable (3) 1,039 3,147 Other 5,417 5,691 Total $ 42,352 $ 45,802 (1) Represents minimum volumes of product we are required to leave on certain third-party owned pipelines under long-term shipment commitments. At June 30, 2022 and March 31, 2022, linefill consisted of 423,978 barrels of crude oil. Linefill held in pipelines we own is included within property, plant and equipment (see Note 4). (2) Represents the noncurrent portion of minimum shipping fees paid in excess of volumes shipped, or deficiency credits, for a contract with a crude oil pipeline operator. This amount can be recovered when volumes shipped exceed the minimum monthly volume commitment (see Note 7). As of June 30, 2022, the deficiency credit was $12.1 million, of which $4.3 million is recorded within prepaid expenses and other current assets in our unaudited condensed consolidated balance sheet. (3) Represents the noncurrent portion of a loan receivable, net of an allowance for an expected credit loss, with a former related party. During the three months ended June 30, 2022, we received a $2.0 million prepayment for this loan receivable and also reduced the final payment due July 31, 2023 to $1.1 million. We discounted the final payment to its net present value with the amount of the reduction in the value of the final payment recorded as a loss within (gain) loss on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations. Accrued Expenses and Other Payables Accrued expenses and other payables consist of the following at the dates indicated: June 30, 2022 March 31, 2022 (in thousands) Accrued interest $ 85,063 $ 56,104 Derivative liabilities 23,013 27,108 Accrued compensation and benefits 16,622 18,417 Excise and other tax liabilities 10,301 10,451 Product exchange liabilities 8,211 853 Other 35,891 27,786 Total $ 179,101 $ 140,719 Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” This ASU (i) simplifies an issuer’s accounting for convertible instruments by eliminating two of the three models in Accounting Standards Codification (“ASC”) 470-20 that require separate accounting for embedded conversion features, (ii) amends diluted earnings per share calculations for convertible instruments by requiring the use of the if-converted method and (iii) simplifies the settlement assessment entities are required to perform on contracts that can potentially settle in an entity’s own equity by removing certain requirements. We adopted this guidance on April 1, 2022, using the modified retrospective method. Under our Class D Preferred Unit (as defined in Note 8) agreement, we are permitted to issue common units to redeem a portion of the outstanding Class D Preferred Units. Using the if-converted method, we expect our calculation of earnings per unit to be impacted by both an increase in the number of diluted weighted average common units outstanding and a decrease in the amount of Class D Preferred Unit distributions, when they are determined to be dilutive. Other than the potential impact to our future earnings per unit calculations, the adoption of this guidance did not impact our financial position, results of operations or cash flows related to any debt or preferred units issued prior to adoption. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective prospectively upon issuance through December 31, 2022 and may be applied from the beginning of an interim period that includes the issuance date of this ASU. On April 13, 2022, the ABL Facility (as defined herein) was amended to replace the LIBOR benchmark with the SOFR (as defined herein) benchmark (as discussed further in Note 6). We are continuing to evaluate the effect that this guidance will have on our financial position, results of operations and cash flows.

The 2026 Senior Secured Notes mature on February 1, 2026. The 2026 Senior Secured Notes were issued pursuant to an indenture dated February 4, 2021 (the “Indenture”). The 2026 Senior Secured Notes are secured by first priority liens on substantially all of our assets other than our accounts receivable, inventory, pledged deposit accounts, cash and cash equivalents, renewable energy tax credits and related assets and second priority liens on our accounts receivable, inventory, pledged deposit accounts, cash and cash equivalents, renewable energy tax credits and related assets. The Indenture contains covenants that, among other things, limit our ability to: pay distributions or make other restricted payments or repurchase stock; incur or guarantee additional indebtedness or issue disqualified stock or certain preferred stock; make certain investments; create or incur liens; sell assets; enter into restrictions affecting the ability of restricted subsidiaries to make distributions, make loans or advances or transfer assets to the guarantors (including the Partnership); enter into certain transactions with our affiliates; designate restricted subsidiaries as unrestricted subsidiaries; and merge, consolidate or transfer or sell all or substantially all of our assets. The Indenture specifically restricts our ability to pay distributions until our total leverage ratio (as defined in the Indenture) for the most recently ended four full fiscal quarters at the time of the distribution is not greater than 4.75 to 1.00. These covenants are subject to a number of important exceptions and qualifications. Compliance At June 30, 2022, we were in compliance with the covenants under the 2026 Senior Secured Notes Indenture. ABL Facility The $500.0 million ABL Facility is subject to a borrowing base, which includes a sub-limit for letters of credit. The initial borrowing base was $500.0 million. On April 13, 2022, we amended the ABL Facility to increase the commitments to $600.0 million under the accordion feature within the ABL Facility. As part of the amendment, we agreed to reduce the commitments back to $500.0 million on or before March 31, 2023. In addition, the sub-limit for letters of credit was increased to $250.0 million and the LIBOR benchmark was replaced with an adjusted forward-looking term rate based on the secured overnight financing rate (“SOFR”) as the interest rate benchmark. The ABL Facility is secured by a lien on substantially all of our assets, including among other things, a first priority lien on our accounts receivable, inventory, pledged deposit accounts, cash and cash equivalents, renewable energy tax credits and related assets and a second priority lien on all of our other assets. At June 30, 2022, $171.0 million had been borrowed under the ABL Facility and we had letters of credit outstanding of approximately $143.6 million. The ABL Facility is scheduled to mature at the earliest of (a) February 4, 2026 or (b) 91 days prior to the earliest maturity date in respect to any of our indebtedness in an aggregate principal amount of $50.0 million or greater, if such indebtedness is outstanding at such time, subject to certain exceptions. At June 30, 2022, the borrowings under the ABL Facility had a weighted average interest rate of 4.84% calculated as the prime rate of 4.75% plus a margin of 1.75% on the alternate base borrowings and the weighted average SOFR of 1.28% plus a margin of 2.75% for the SOFR borrowings. On June 30, 2022, the interest rate in effect on letters of credit was 2.75%. The ABL Facility contains various affirmative and negative covenants, including financial reporting requirements and limitations on indebtedness, liens, mergers, consolidations, liquidations and dissolutions, sales of assets, distributions and other restricted payments, investments (including acquisitions) and transactions with affiliates. The ABL Facility contains, as the only financial covenant, a fixed charge coverage ratio that is tested based on the financial statements for the most recently ended fiscal quarter upon the occurrence and during the continuation of a Cash Dominion Event (as defined in the ABL Facility). At June 30, 2022, no Cash Dominion Event had occurred. Compliance At June 30, 2022, we were in compliance with the covenants under the ABL Facility. Senior Unsecured Notes The senior unsecured notes include the 2023 Notes, 2025 Notes and 2026 Notes (collectively, the “Senior Unsecured Notes”). Repurchases The following table summarizes repurchases of Senior Unsecured Notes for the period indicated: Three Months Ended June 30, 2022 (in thousands) 2023 Notes Notes repurchased $ 23,260 Cash paid (excluding payments of accrued interest) $ 21,517 Gain on early extinguishment of debt (1) $ 1,662 (1) Gain on early extinguishment of debt for the three months ended June 30, 2022 is inclusive of the write-off of debt issuance costs of $0.1 million.

Compliance At June 30, 2022, we were in compliance with the covenants under all of the Senior Unsecured Notes indentures. Other Long-term Debt On October 29, 2020, we entered into an equipment loan for $45.0 million which bears interest at a rate of 8.6% and is secured by certain of our barges and towboats. We have an aggregate principal balance of $41.1 million at June 30, 2022. The loan matures on November 1, 2027.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Commitments and Contingencies Legal Contingencies In August 2015, LCT Capital, LLC (“LCT”) filed a lawsuit against 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. 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 (the “December 5th Order”). 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 January 7, 2020, the Supreme Court of Delaware (“Supreme Court”) entered an Order accepting an interlocutory appeal of various issues relating to both the quantum meruit and fraudulent misrepresentation verdicts. The Supreme Court heard oral arguments of the parties on November 4, 2020, took the matters presented under advisement and on January 28, 2021, issued a ruling that (a) LCT is not entitled to “benefit-of-the-bargain” damages on its fraud claim; (b) LCT is not entitled to receive fraudulent misrepresentation damages separate from its quantum meruit damages; (c) the trial court abused its discretion when it ordered a new trial on damages relating to LCT’s claim of fraudulent misrepresentation; and (d) the trial court properly ordered a new trial on LCT’s claim of quantum meruit damages. The date for a new trial, to be limited to the quantum meruit claim, has been set by the trial court for November 7, 2022. Any allocation of the ultimate verdict award, if any, between the GP and the Partnership will be made by the board of directors of our GP once all information is available to it and after the new trial, any post-trial and/or any appellate process has concluded and the verdict is final as a matter of law. As of June 30, 2022, 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, 2022, we have an environmental liability, measured on an undiscounted basis, of $1.7 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, 2022 $ 29,941 Liabilities incurred 146 Liabilities associated with disposed assets (1) (85) Liabilities settled (93) Accretion expense 441 Balance at June 30, 2022 $ 30,350 (1) Relates to the sale of two saltwater disposal wells. 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. 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, 2022 (in thousands): Fiscal Year Ending March 31, 2023 (nine months) $ 26,510 2024 35,410 2025 30,897 Total $ 92,817 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.

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, 2022, we had the following commodity sale commitments: Crude Oil Natural Gas Liquids Value Volume Value Volume (in thousands) Fixed-Price Commodity Sale Commitments: 2023 (nine months) $ 164,585 1,486 $ 180,624 132,794 2024 — — 13,418 14,078 2025 — — 979 916 Total $ 164,585 1,486 $ 195,021 147,788 Index-Price Commodity Sale Commitments: 2023 (nine months) $ 2,741,022 26,913 $ 1,001,257 669,878 2024 924,914 10,858 23,565 19,138 2025 791,056 10,220 — — 2026 28,963 390 — — Total $ 4,485,955 48,381 $ 1,024,822 689,016 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 9) 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 9 and represent $37.9 million of our prepaid expenses and other current assets and $19.9 million of our accrued expenses and other payables at June 30, 2022. 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, 2022 (in thousands): Fiscal Year Ending March 31, 2023 (nine months) $ 8,199 2024 8,468 2025 3,236 2026 1,203 2027 1,189 2028 1,189 Thereafter 4,140 Total $ 27,624 As part of the acquisition of Hillstone Environmental Partners, LLC, 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, 2022 and 2021, we recorded $0.4 million and $0.6 million, respectively, within operating expense in our unaudited condensed consolidated statements of operations. At June 30, 2022, the range of potential payments we could be obligated to make pursuant to the subsidy agreement could be from $0.0 million to $1.6 million.

Equity

Equity	3 Months Ended
	Jun. 30, 2022
Equity [Abstract]
Equity	Equity Partnership Equity The Partnership’s equity consists of a 0.1% GP interest and a 99.9% limited partner interest, which consists of common units. Our GP has the right, but not the obligation, to contribute a proportionate amount of capital to us to maintain its 0.1% GP interest. Our GP is not required to guarantee or pay any of our debts and obligations. At June 30, 2022, we owned 8.69% of our GP. Suspension of Common Unit and Preferred Unit Distributions The board of directors of our GP temporarily suspended all distributions (common unit distributions which began with the quarter ended December 31, 2020 and preferred unit distributions which began with the quarter ended March 31, 2021) in order to deleverage our balance sheet and meet the financial performance ratios set within the Indenture of the 2026 Senior Secured Notes, as discussed further in Note 6. Class B Preferred Units As of June 30, 2022, there were 12,585,642 of our 9.00% Class B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (“Class B Preferred Units”) outstanding. 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). For the quarter ended June 30, 2022, we did not declare or pay distributions to the holders of the Class B Preferred Units, thus the quarterly distribution for June 30, 2022 is $0.5625 and the cumulative distribution since suspension for each Class B Preferred Unit is $3.375. In addition, the amount of cumulative but unpaid distributions shall continue to accumulate at the then applicable rate until all unpaid distributions have been paid in full. The total amount due as of June 30, 2022 is $44.7 million. On July 1, 2022, the Class B Preferred Units distributions on and after July 1, 2022 began accumulating at a percentage of the $25.00 liquidation preference equal to the applicable three-month LIBOR interest rate (or alternative rate as determined in accordance with the partnership agreement) plus a spread of 7.213%. Class C Preferred Units As of June 30, 2022, there were 1,800,000 of our 9.625% Class C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units (“Class C Preferred Units”) outstanding. 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). For the quarter ended June 30, 2022, we did not declare or pay distributions to the holders of the Class C Preferred Units, thus the quarterly distribution for June 30, 2022 is $0.6016 and the cumulative distribution since suspension for each Class C Preferred Unit is $3.6094. In addition, the amount of cumulative but unpaid distributions shall continue to accumulate at the then applicable rate until all unpaid distributions have been paid in full. The total amount due as of June 30, 2022 is $6.9 million. Class D Preferred Units As of June 30, 2022, there were 600,000 preferred units (“Class D Preferred Units”) and warrants exercisable to purchase an aggregate of 25,500,000 common units 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), plus an additional 1.5% rate increase due to us exceeding the adjusted total leverage ratio and due to a Class D distribution payment default, as defined within the amended and restated limited partnership agreement. For the quarter ended June 30, 2022, we did not declare or pay distributions to the holders of the Class D Preferred Units, thus the average quarterly distribution at June 30, 2022 is $27.32 and the average cumulative distribution since suspension for each Class D Preferred unit is $162.60. In addition, the amount of cumulative but unpaid distributions shall continue to accumulate at the then applicable rate until all unpaid distributions have been paid in full. The total amount due as of June 30, 2022 is $103.9 million. On July 1, 2022, the current distribution rate for the Class D Preferred Units increased to 10.00% per year per unit, plus an additional 1.5% rate increase due to us exceeding the adjusted total leverage ratio and due to a Class D distribution payment default, as described above. Equity-Based Incentive Compensation Our GP adopted a long-term incentive plan (“LTIP”), which allowed for the issuance of equity-based compensation. Our GP 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 Service Awards may also vest upon a change of control, at the discretion of the board of directors of our GP. No distributions accrue to or are paid on the Service Awards during the vesting period. The LTIP expired on May 10, 2021. The following table summarizes the Service Award activity during the three months ended June 30, 2022: Weighted-Average Grant Date Number of Fair Value Units Per Unit Unvested Service Award units at March 31, 2022 2,188,800 $2.15 Units forfeited (49,500) $2.15 Unvested Service Award units at June 30, 2022 2,139,300 $2.15 As the LTIP expired on May 10, 2021, we had no common units available for grant for the three months ended June 30, 2022. As of June 30, 2022, there are 1,426,075 unvested Service Award units which are expected to vest during the year ending March 31, 2023 and 713,225 unvested Service Award units which are expected to vest during the year ending March 31, 2024. Also, any current unvested Service Awards that are forfeited or canceled will not be available for future grants. 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. 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, 2022 and 2021, we recorded compensation expense related to Service Award units of $0.5 million and $1.0 million, respectively. For the unvested Service Award units, as of June 30, 2022, we had estimated future expense of $2.7 million which we expect to record during the year ending March 31, 2023 and $1.3 million which we expect to record during the year ending March 31, 2024.

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, 2022 and 2021, we recorded net losses of $41.1 million and $56.7 million, respectively, from our commodity derivatives to revenues and cost of sales in our unaudited condensed consolidated statements of operations. 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, 2022, 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 ABL Facility is variable-rate debt with interest rates that are generally indexed to the Wall Street Journal prime rate or LIBOR interest rate (or successor rate, which has since been determined to be SOFR). At June 30, 2022, we had $171.0 million of outstanding borrowings under the ABL Facility at a weighted average interest rate of 4.84%. In addition, on and after certain dates, distributions for our Class B Preferred Units and Class C Preferred Units will be calculated using the applicable three-month LIBOR interest rate (or alternative rate as determined in accordance with the partnership agreement) plus a spread (see Note 8 for a further discussion). On and after a certain date, the holders of the Class D Preferred Units can elect, from time to time, for the distributions to be calculated based on the applicable three-month LIBOR interest rate (or alternative rate as determined in accordance with the partnership agreement) plus a spread (“Class D Variable Rate”, as defined in the partnership agreement). Each Class D Variable Rate election shall be effective for at least four quarters following such election. Fair Value of Fixed-Rate Notes The following table provides fair value estimates of our fixed-rate notes at June 30, 2022 (in thousands): Senior Secured Notes: 2026 Senior Secured Notes $ 1,843,292 Senior Unsecured Notes: 2023 Notes $ 409,837 2025 Notes $ 286,282 2026 Notes $ 241,130 For the 2026 Senior Secured Notes and 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.

Segments

Segment Reporting [Abstract]
Segments	Segments Our operations are organized into three reportable segments: (i) Water Solutions, (ii) Crude Oil Logistics and (iii) Liquids Logistics, consistent with the manner in which our chief operating decision maker evaluates performance and allocates resources. These segments have been identified based on the differing products and services, regulatory environment and the expertise required for these operations. Our Liquids Logistics reportable segment includes operating segments that have been aggregated based on the nature of the products and services provided. Operating income of these segments is reviewed by the chief operating decision maker to evaluate performance and make business decisions. Intersegment transactions are recorded based on prices negotiated between the segments and are eliminated upon consolidation. See Note 1 for a discussion of the products and services of our reportable segments. The remainder of our business operations is presented as “Corporate and Other” and consists of certain corporate expenses that are not allocated to the reportable segments.

The other owner of KAIR2014, our Chief Executive Officer, H. Michael Krimbill, is a party to a similar guarantee. This guarantee obligates us for the payment and performance of KAIR2014 with respect to the repayment of the loan. As of June 30, 2022, the outstanding balance of the loan is approximately $2.5 million. Payments are made monthly, reducing the outstanding balance, and the loan matures in September 2023. As the guarantee is joint and several, we could be liable for the entire outstanding balance of the loan. The loan is collateralized by the airplane owned by KAIR2014 and in the event of a default, the lender could seek payment in full from us. As of June 30, 2022, no accrual has been recorded related to this guarantee.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customer	Revenue from Contracts with Customers 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, 2022. 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 10 for a detail of disaggregated revenue. Revenue from contracts accounted for as derivatives under ASC 815 within our Liquids Logistics segment includes $5.1 million of net losses related to changes in the mark-to-market value of these arrangements recorded during the three months ended June 30, 2022. 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 utilized 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, 2022 (in thousands): Fiscal Year Ending March 31, 2023 (nine months) $ 114,830 2024 105,297 2025 73,235 2026 17,240 2027 3,727 2028 1,269 Thereafter 803 Total $ 316,401 Contract Assets and Liabilities The following tables summarize the balances of our contract assets and liabilities at the dates indicated: June 30, 2022 March 31, 2022 (in thousands) Accounts receivable from contracts with customers $ 590,488 $ 605,384 Contract assets (current) $ 1,467 $ — Contract liabilities balance at March 31, 2022 $ 7,667 Payment received and deferred 27,799 Payment recognized in revenue (13,819) Contract liabilities balance at June 30, 2022 $ 21,647

Allowance for Current Expected Credit Loss	3 Months Ended

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, 2022 $ 2,626 $ 458 Change in provision for expected credit losses (1) (418) Balance at June 30, 2022 $ 2,625 $ 40

Due to the bankruptcy of the third-party, we wrote down the remaining outstanding balance to what we expected to collect as an unsecured claim. As of March 31, 2022, the outstanding balance of our unsecured claim was $0.6 million, net of an allowance for an expected credit loss, which was recorded within prepaid expenses and other current assets in our consolidated balance sheet. During the three months ended June 30, 2022, we received $1.0 million to settle our unsecured claim and we reversed the allowance for the expected credit loss.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	3 Months Ended
	Jun. 30, 2022
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, 2022 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2022 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on June 6, 2022. 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, 2023.
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.
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 $42.9 million and $43.5 million at June 30, 2022 and March 31, 2022, 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 sheets. 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, 2022 was $0.7 million with an effective tax rate of 24.1%. The deferred tax benefit recorded during the three months ended June 30, 2021 was $1.1 million with an effective tax rate of 23.1%. 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 uncertain tax positions that required recognition in our unaudited condensed consolidated financial statements at June 30, 2022 or March 31, 2022.
Inventories	InventoriesOur 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.
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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” This ASU (i) simplifies an issuer’s accounting for convertible instruments by eliminating two of the three models in Accounting Standards Codification (“ASC”) 470-20 that require separate accounting for embedded conversion features, (ii) amends diluted earnings per share calculations for convertible instruments by requiring the use of the if-converted method and (iii) simplifies the settlement assessment entities are required to perform on contracts that can potentially settle in an entity’s own equity by removing certain requirements. We adopted this guidance on April 1, 2022, using the modified retrospective method. Under our Class D Preferred Unit (as defined in Note 8) agreement, we are permitted to issue common units to redeem a portion of the outstanding Class D Preferred Units. Using the if-converted method, we expect our calculation of earnings per unit to be impacted by both an increase in the number of diluted weighted average common units outstanding and a decrease in the amount of Class D Preferred Unit distributions, when they are determined to be dilutive. Other than the potential impact to our future earnings per unit calculations, the adoption of this guidance did not impact our financial position, results of operations or cash flows related to any debt or preferred units issued prior to adoption. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective prospectively upon issuance through December 31, 2022 and may be applied from the beginning of an interim period that includes the issuance date of this ASU. On April 13, 2022, the ABL Facility (as defined herein) was amended to replace the LIBOR benchmark with the SOFR (as defined herein) benchmark (as discussed further in Note 6). We are continuing to evaluate the effect that this guidance will have on our financial position, results of operations and cash flows.

Asset Retirement Obligation	Asset Retirement ObligationsWe 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.

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. 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.
