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, 2023, 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.

Significant Accounting Policies

Significant Accounting Policies	Jun. 30, 2023
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, 2023 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2023 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 31, 2023. 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, 2024. 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 collectability 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 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 $40.5 million and $40.7 million at June 30, 2023 and March 31, 2023, 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, 2023 was $0.1 million with an effective tax rate of 22.3%. 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%. 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, 2023 or March 31, 2023. 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, 2023 March 31, 2023 (in thousands) Propane $ 64,308 $ 46,910 Butane 51,837 18,384 Crude oil 47,114 49,586 Biodiesel 14,075 19,778 Ethanol 1,862 3 Diesel 1,312 2,536 Other 5,130 5,410 Total $ 185,638 $ 142,607 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, 2023 March 31, 2023 (in thousands) Water services and land company Water Solutions 50% $ 14,494 $ 15,036 Water services and land company Water Solutions 10% 3,061 3,511 Water services and land company Water Solutions 50% 2,089 2,071 Aircraft company (1) Corporate and Other 50% 253 308 Natural gas liquids terminal company Liquids Logistics 50% 152 164 Total $ 20,049 $ 21,090 (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, 2023 March 31, 2023 (in thousands) Linefill (1) $ 37,861 $ 37,861 Loan receivable (2) 10,308 8,592 Minimum shipping fees - pipeline commitments (3) 3,560 4,628 Other 5,700 6,896 Total $ 57,429 $ 57,977 (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, 2023 and March 31, 2023, linefill consisted of 502,686 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 loan receivables, net of allowances for expected credit losses, related to the sale of certain saltwater disposal assets (see Note 15). (3) 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). At June 30, 2023, the deficiency credit was $7.8 million, of which $4.3 million is recorded within prepaid expenses and other current assets in our unaudited condensed consolidated balance sheet. Accrued Expenses and Other Payables Accrued expenses and other payables consist of the following at the dates indicated: June 30, 2023 March 31, 2023 (in thousands) Accrued interest $ 77,736 $ 49,362 Accrued compensation and benefits 14,673 27,013 Excise and other tax liabilities 12,897 11,777 Derivative liabilities 12,874 14,752 Product exchange liabilities 7,515 4,047 Other 33,713 26,665 Total $ 159,408 $ 133,616 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 Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 the London Interbank Offered Rate (“LIBOR”) interest rate or another reference rate expected to be discontinued because of reference rate reform. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” which deferred the sunset date from December 31, 2022 to December 31, 2024 and left all other provisions of ASU 2020-04 unchanged. 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. We have the option to redeem all or a portion of the 2026 Senior Secured Notes at any time at fixed redemption prices contained within the Indenture. If we experience certain kinds of change of control triggering events, we will be required to offer to repurchase the 2026 Senior Secured Notes at 101% of the aggregate principal amount of the 2026 Senior Secured Notes repurchased plus accrued and unpaid interest on the 2026 Senior Secured Notes repurchased to, but not including, the date of purchase. Compliance At June 30, 2023, we were in compliance with the covenants under the Indenture. ABL Facility The ABL Facility is subject to a borrowing base, which includes a sub-limit for letters of credit. Total commitments under the ABL Facility are $600.0 million and the sub-limit for letters of credit is $250.0 million. 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, 2023, $180.0 million had been borrowed under the ABL Facility and we had letters of credit outstanding of approximately $141.7 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, 2023, the borrowings under the ABL Facility had a weighted average interest rate of 8.28% calculated as the prime rate of 8.25% plus a margin of 1.50% on the alternate base borrowings and the weighted average secured overnight financing rate (“SOFR”) of 5.22% plus a margin of 2.50% on the SOFR borrowings. On June 30, 2023, the interest rate in effect on letters of credit was 2.50%. 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, 2023, no Cash Dominion Event had occurred. Compliance At June 30, 2023, we were in compliance with the covenants under the ABL Facility. Senior Unsecured Notes The senior unsecured notes include the 2025 Notes, which mature on March 1, 2025 and the 2026 Notes, which mature on April 15, 2026 (collectively, the “Senior Unsecured Notes”). Repurchases The following table summarizes repurchases of Senior Unsecured Notes for the period indicated: Three Months Ended June 30, 2023 (in thousands) 2025 Notes Notes repurchased $ 99,275 Cash paid (excluding payments of accrued interest) $ 91,982 Gain on early extinguishment of debt (1) $ 6,906 (1) Gain on early extinguishment of debt for the 2025 Notes during the three months ended June 30, 2023 is inclusive of the write-off of debt issuance costs of $0.4 million.

Commitments and Contingencies	Jun. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 re-trial of the quantum meruit claim was conducted in Delaware state court from February 6, 2023 through February 15, 2023 and resulted in the jury returning a verdict consisting of an award of $36.0 million subject to statutory interest and costs, as applicable, which through June 30, 2023, equals approximately $21.0 million. The GP and the Partnership contend that the jury verdict is not supportable by controlling law or the evidentiary record; and on July 28, 2023, filed their notice of appeal to the Delaware Supreme Court which raises various issues relating to the quantum meruit verdict, including but not limited to, certain written orders and oral evidentiary and other rulings made prior to and during the February 2023 remand trial. 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 any post-trial and/or any appellate process has concluded and the verdict is final as a matter of law. As of June 30, 2023, we have accrued approximately $4.0 million related to this matter, of which approximately $1.5 million represents interest accrued through June 30, 2023. The Partnership is a party defendant to a purported class action complaint filed in the federal court in the Northern District of Oklahoma styled Gary R. Underwood, Successor Trustee for the James L. Price Revocable Living Trust, on behalf of the Trust and all others similarly situated v. NGL Energy Partners LP , Case No. 4:21-cv-00135-CVE-SH. This case seeks class certification on behalf of owners who allege the Partnership’s Crude Oil Logistics group violated Oklahoma’s Production Revenue Standards Act when it failed to include statutory interest on proceeds payments it made to certain mineral owners and to state unclaimed property divisions for oil purchased from certain Oklahoma wells. A substantial portion of the statutory interest claimed to be owed in the lawsuit related to suspended proceeds we inherited from our predecessors and remitted to various state unclaimed property divisions in 2016. With no admission of liability or wrongdoing, but only to avoid the expense and uncertainty of future litigation, the Partnership entered into a settlement agreement in this case to resolve all claims made against it by the plaintiff and the proposed class. We have agreed to pay the sum of approximately $8.4 million to the plaintiff and the proposed class. On April 3, 2023, we paid this money into escrow. During the final fairness hearing on June 15, 2023, the settlement agreement was approved by the court and an order granting final approval of the class action settlement was entered into record. 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, 2023, we have an environmental liability, measured on an undiscounted basis, of $1.4 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, 2023 $ 35,163 Liabilities incurred 761 Liabilities associated with disposed assets (1) (202) Liabilities settled (218) Accretion expense 956 Balance at June 30, 2023 $ 36,460 (1) Relates to the sale of three saltwater disposal wells and other long-lived assets within our Water Solutions business. 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 Agreement We have a noncancellable agreement with a crude oil pipeline operator, which guarantees us minimum monthly shipping capacity on the pipeline. As a result, we are required to pay the minimum shipping fees if actual shipments are less than our allotted capacity. Under this agreement, 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, and this agreement allows 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 this agreement at June 30, 2023 (in thousands): Fiscal Year Ending March 31, 2024 (nine months) $ 20,179 2025 26,784 Total $ 46,963 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.

Equity

Equity	3 Months Ended
Equity	Jun. 30, 2023
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 the Partnership 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, 2023, 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, 2023, there were 12,585,642 of our 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 a floating rate of the three-month LIBOR interest rate (5.55% for the quarter ended June 30, 2023) plus a spread of 7.213%. Effective July 3, 2023, the reference to LIBOR in the formulation for the distribution rate in these securities was replaced with three-month CME Term SOFR, as calculated and published by CME Group Benchmark Administration, Ltd., plus a tenor spread adjustment of 0.26161%, in accordance with the Adjustable Interest R ate (LIBOR) Act (the “LIBOR Act”), and the rules implementing the LIBOR Act. For the quarter ended June 30, 2023, we did not declare or pay distributions to the holders of the Class B Preferred Units, thus the quarterly distribution for June 30, 2023 is $0.7974 and the cumulative distribution since suspension for each Class B Preferred Unit is $6.2003. 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, 2023 is $86.4 million. Class C Preferred Units As of June 30, 2023, there were 1,800,000 of our 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, 2023, we did not declare or pay distributions to the holders of the Class C Preferred Units, thus the quarterly distribution for June 30, 2023 is $0.6016 and the cumulative distribution since suspension for each Class C Preferred Unit is $6.0157. 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, 2023 is $12.0 million. On and after April 15, 2024, distributions on the Class C Preferred Units will accumulate 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 amended and restated limited partnership agreement (the “Partnership Agreement”)) plus a spread of 7.384%. Class D Preferred Units As of June 30, 2023, 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 following table summarizes the outstanding warrants at June 30, 2023: Issuance Date and Description Number of Warrants Exercise Price July 2, 2019 Premium warrants 10,000,000 $ 17.45 Par warrants 7,000,000 $ 14.54 October 31, 2019 Premium warrants 5,000,000 $ 16.28 Par warrants 3,500,000 $ 13.56 All outstanding warrants are currently exercisable and any unexercised warrants will expire on the tenth anniversary of the date of issuance. The warrants will not participate in cash distributions. The current distribution rate for the Class D Preferred Units is 10.00% (equal to $100.00 per every $1,000 in unit value per year), and includes an additional 0.50% rate increase due to a Class D distribution payment default, as defined within the Partnership Agreement. For the quarter ended June 30, 2023, we did not declare or pay distributions to the holders of the Class D Preferred Units, thus the average quarterly distribution at June 30, 2023 is $27.31 and the average cumulative distribution since suspension for each Class D Preferred unit is $279.65. 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, 2023 is $188.0 million. On or after July 1, 2024, the holders of our Class D Preferred Units can elect, from time to time, for the distributions to be calculated based on a floating rate equal to the applicable three-month LIBOR interest rate (or alternative rate as determined in accordance with the Partnership Agreement) plus a spread of 7.00% (“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. Total Preferred Unit Distributions in Arrears The total preferred unit distributions in arrears for all classes of preferred units are $286.4 million as of June 30, 2023. 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, 2023: Weighted-Average Grant Date Number of Fair Value Units Per Unit Unvested Service Award units at March 31, 2023 627,975 $2.15 Units forfeited (3,250) $2.15 Unvested Service Award units at June 30, 2023 624,725 $2.15 As the LTIP expired on May 10, 2021, we had no common units available for grant during the three months ended June 30, 2023. As of June 30, 2023, there are 624,725 unvested Service Awards which are expected to vest on November 15, 2023. 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, 2023 and 2022, we recorded compensation expense related to Service Awards of $0.5 million and $0.5 million, respectively. For the unvested Service Awards at June 30, 2023, we had estimated future expense of $0.7 million which we expect to record by November 15, 2023.

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, 2023 and 2022, we recorded net gains of $12.9 million and net losses of $41.1 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, 2023, 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 prime rate or SOFR, an adjusted forward-looking term rate based on the secured overnight financing rate. At June 30, 2023, we had $180.0 million of outstanding borrowings under the ABL Facility at a weighted average interest rate of 8.28%. The current distribution rate for the Class B Preferred Units is a floating rate of the three-month LIBOR interest rate (5.55% for the quarter ended June 30, 2023) plus a spread of 7.213%. Effective July 3, 2023, the reference to LIBOR in the formulation for the distribution rate in these securities was replaced with three-month CME Term SOFR plus a tenor spread adjustment of 0.26161% in accordance with the LIBOR Act and the rules implementing the LIBOR Act. On and after April 15, 2024, distributions on the Class C Preferred Units will accumulate 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 7.384%. On or after July 1, 2024, the holders of our Class D Preferred Units can elect, from time to time, for the distributions to be calculated based on a floating rate equal to the applicable three-month LIBOR interest rate (or alternative rate as determined in accordance with the Partnership Agreement) plus the Class D Variable Rate. 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, 2023 (in thousands): 2026 Senior Secured Notes $ 2,014,125 2025 Notes $ 269,866 2026 Notes $ 300,601 For the 2026 Senior Secured Notes, 2025 Notes and 2026 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	Jun. 30, 2023
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, 2023, the outstanding balance of the loan is approximately $2.2 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, 2023, 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, 2023. The majority of our revenue agreements are in the 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 in the scope of ASC 845 and ASC 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 $1.7 million of net gains related to changes in the mark-to-market value of these contracts recorded during the three months ended June 30, 2023. 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 contracts. The following table summarizes the amount and timing of revenue recognition for such contracts at June 30, 2023 (in thousands): Fiscal Year Ending March 31, 2024 (nine months) $ 88,981 2025 92,003 2026 26,893 2027 10,630 2028 1,271 2029 457 Thereafter 346 Total $ 220,581 Contract Assets and Liabilities The following tables summarize the balances of our contract assets and liabilities at the dates indicated: June 30, 2023 March 31, 2023 (in thousands) Accounts receivable from contracts with customers $ 353,891 $ 425,760 Contract assets (current) $ — $ 10,050 Contract liabilities balance at March 31, 2023 $ 14,520 Payment received and deferred 8,396 Payment recognized in revenue (4,146) Contract liabilities balance at June 30, 2023 $ 18,770

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 for expected credit losses. 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 for the period indicated: Accounts Receivable - Trade Notes Receivable and Other (in thousands) Balance at March 31, 2023 $ 1,964 $ 48 Change in provision for expected credit losses (43) 34 Write-offs charged against the provision (33) — Balance at June 30, 2023 $ 1,888 $ 82

Interest on the loan receivable is based on the prime rate and is due monthly beginning on August 1, 2023. The loan receivable matures on December 31, 2025. We recorded a loss of $5.4 million within gain on disposal or impairment of assets, net in our unaudited condensed consolidated statement of operations for the three months ended June 30, 2023 . As this sale transaction did not represent a strategic shift that will have a major effect on our operations or financial results, operations related to this portion of our Water Solutions segment have not been classified as discontinued operations.

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, 2023 was derived from our audited consolidated financial statements for the fiscal year ended March 31, 2023 included in our Annual Report on Form 10-K (“Annual Report”) filed with the SEC on May 31, 2023. 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, 2024.
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 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 $40.5 million and $40.7 million at June 30, 2023 and March 31, 2023, 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, 2023 was $0.1 million with an effective tax rate of 22.3%. 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%. 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, 2023 or March 31, 2023.
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.
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 Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 the London Interbank Offered Rate (“LIBOR”) interest rate or another reference rate expected to be discontinued because of reference rate reform. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” which deferred the sunset date from December 31, 2022 to December 31, 2024 and left all other provisions of ASU 2020-04 unchanged. 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.

Revenue from Contract with Customer [Abstract]
Revenue recognition	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, 2023. The majority of our revenue agreements are in the 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 in the scope of ASC 845 and ASC 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 $1.7 million of net gains related to changes in the mark-to-market value of these contracts recorded during the three months ended June 30, 2023.

Allowance for Current Expected Credit Loss (Policies)	Jun. 30, 2023
Credit Loss [Abstract]
Expected credit loss	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 for expected credit losses. We manage receivable pools using past due balances as a key credit quality indicator.
