Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	ORGANIZATION AND BASIS OF PRESENTATION Organization and Operations NuStar Energy L.P. (NYSE: NS) is a Delaware limited partnership primarily engaged in the transportation, terminalling and storage of petroleum products and renewable fuels and the transportation of anhydrous ammonia. Unless otherwise indicated, the terms “NuStar Energy,” “NS,” “the Partnership,” “we,” “our” and “us” are used in this report to refer to NuStar Energy L.P., to one or more of our consolidated subsidiaries or to all of them taken as a whole. Our business is managed under the direction of the board of directors of NuStar GP, LLC, the general partner of our general partner, Riverwalk Logistics, L.P., both of which are indirectly wholly owned subsidiaries of ours. We conduct our operations through our subsidiaries, primarily NuStar Logistics, L.P. (NuStar Logistics) and NuStar Pipeline Operating Partnership L.P. (NuPOP). We have three business segments: pipeline, storage and fuels marketing. Recent Developments Partial Redemptions of Series D Preferred Units. On June 30, 2023, we redeemed an aggregate 5,500,000 of our Series D Cumulative Convertible Preferred Units (Series D Preferred Units), at a price per unit of $31.88, for an aggregate purchase price of $175.3 million. On June 29, 2023, NuStar Energy L.P. notified the holders of our Series D Preferred Units of our intent to exercise our right to redeem an aggregate 2,560,000 of our Series D Preferred Units, at a price per unit of $32.18 for an aggregate purchase price of $82.4 million. This redemption closed on July 31, 2023. Please see Note 6 for additional information on these redemptions. Debt Amendments. On June 30, 2023, we amended our $1.0 billion unsecured revolving credit agreement, mainly to extend the maturity date from April 27, 2025 to January 27, 2027. On June 29, 2023, we amended our $100.0 million receivables financing agreement to extend the scheduled termination date from January 31, 2025 to July 1, 2026. Please refer to Note 4 for more information. Basis of Presentation These unaudited condensed consolidated financial statements include the accounts of the Partnership and subsidiaries in which the Partnership has a controlling interest. Inter-partnership balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, and all disclosures are adequate. All such adjustments are of a normal recurring nature unless disclosed otherwise. Operating results for the six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022.

Discontinued Operations and Disposal Groups [Abstract]
DISPOSITIONS	DISPOSITIONS Sale-Leaseback Transaction On March 21, 2023, we sold our corporate headquarters facility and approximately 24 acres of underlying land located in San Antonio, Texas (the Corporate Headquarters) for an aggregate cash sales price of approximately $103.0 million and immediately leased back the Corporate Headquarters for an initial term of twenty years, with two renewal options of ten years each (the Sale-Leaseback Transaction). Upon closing of the sale in the first quarter of 2023, the Sale-Leaseback Transaction qualified as a completed sale, and we recognized a gain of $41.1 million, which is presented in “Gain on sale of assets” on the condensed consolidated statements of comprehensive income. We entered into the Sale-leaseback Transaction in order to monetize the Corporate Headquarters and used the proceeds to repay borrowings on our revolving credit agreement. Pursuant to the lease agreement, rent for the initial term starts at $6.4 million per year and increases annually by 2.5%. At inception of the lease, right-of-use assets and lease liabilities associated with the Sale-Leaseback Transaction assumed a reasonably certain term of 20 years and were included in our consolidated balance sheet as follows (thousands of dollars): Operating lease right-of-use assets: Other long-term assets, net $ 82,230 Operating lease liabilities: Accrued liabilities $ 710 Other long-term liabilities 81,498 Total operating lease liabilities $ 82,208 Following our entrance into the Sale-Leaseback Transaction, the weighted-average discount rate for our operating leases was 6.1%. Point Tupper Terminal Disposition On April 29, 2022, we sold the equity interests in our wholly owned subsidiaries that owned our Point Tupper terminal facility in Nova Scotia, Canada (the Point Tupper Terminal Operations) to EverWind Fuels for $60.0 million. The terminal facility had a storage capacity of 7.8 million barrels and was included in the storage segment. We used the sales proceeds to reduce debt and improve our debt metrics. During the first quarter of 2022, we determined the Point Tupper Terminal Operations met the criteria to be classified as held for sale. We compared the carrying value of the Point Tupper Terminal Operations, which included $42.2 million in cumulative foreign currency translation losses accumulated since our acquisition of the Point Tupper terminal facility in 2005, to its fair value less costs to sell, and we recognized a pre-tax impairment loss of $46.1 million in the first quarter of 2022, which is presented in "Impairment loss" on the condensed consolidated statements of comprehensive income. We believe that the sales price of $60.0 million provided a reasonable indication of the fair value of the Point Tupper Terminal Operations as it represented an exit price in an orderly transaction between market participants. The sales price was a quoted price for identical assets and liabilities in a market that was not active and, thus, our fair value estimate fell within Level 2 of the fair value hierarchy. Upon closing in the second quarter of 2022, we released $39.6 million of foreign currency translation losses from accumulated other comprehensive loss and finalized our sales price, resulting in a gain of $1.6 million, which was presented in “ Other income, net

DEBT

Debt Disclosure [Abstract]
DEBT	DEBT Revolving Credit Agreement On June 30, 2023, we amended our $1.0 billion unsecured revolving credit agreement (the Revolving Credit Agreement), mainly to extend the maturity date from April 27, 2025 to January 27, 2027. The amendment also includes a requirement that we certify that the sum of our Revolving Credit Agreement availability and unrestricted cash balance is no less than $150.0 million on a pro forma basis prior to using any borrowings under the Revolving Credit Agreement to redeem certain unsecured indebtedness or our Series D Preferred Units. As of June 30, 2023, the Revolving Credit Agreement had $750.4 million available for borrowing and $245.0 million of borrowings outstanding. Letters of credit issued under the Revolving Credit Agreement totaled $4.6 million as of June 30, 2023 and limit the amount we can borrow under the Revolving Credit Agreement. Obligations under the Revolving Credit Agreement are guaranteed by NuStar Energy and NuPOP. The Revolving Credit Agreement provides for U.S. dollar borrowings, which bear interest, at our option, based on an alternative base rate or a SOFR-based rate. The Revolving Credit Agreement and certain fees under the Receivables Financing Agreement, defined below, are the only debt arrangements with interest rates that are subject to adjustment if our debt rating is downgraded (or upgraded) by certain credit rating agencies. As of June 30, 2023, our weighted-average interest rate related to borrowings under the Revolving Credit Agreement was 7.7%. The Revolving Credit Agreement is subject to maximum consolidated debt coverage ratio and minimum consolidated interest coverage ratio requirements, which may limit the amount we can borrow to an amount that is less than the total amount available for borrowing. For a rolling period of four quarters, the consolidated debt coverage ratio (as defined in the Revolving Credit Agreement) may not exceed 5.00-to-1.00, and the consolidated interest coverage ratio (as defined in the Revolving Credit Agreement) must not be less than 1.75-to-1.00. As of June 30, 2023, we believe that we are in compliance with the covenants in the Revolving Credit Agreement. Receivables Financing Agreement NuStar Energy and NuStar Finance LLC, a special purpose entity and wholly owned subsidiary of NuStar Energy, are parties to a $100.0 million receivables financing agreement with a third-party lender (the Receivables Financing Agreement) and agreements with certain of NuStar Energy’s wholly owned subsidiaries (collectively with the Receivables Financing Agreement, the Securitization Program). Under the Securitization Program, certain of NuStar Energy’s wholly owned subsidiaries sell their accounts receivable to NuStar Finance on an ongoing basis, and NuStar Finance provides the newly acquired accounts receivable as collateral for its revolving borrowings under the Receivables Financing Agreement. On June 29, 2023, we amended the Receivables Financing Agreement to extend the scheduled termination date from January 31, 2025 to July 1, 2026. As of June 30, 2023, the amount of borrowings outstanding under the Receivables Financing Agreement totaled $71.2 million, the interest rate related to outstanding borrowings was 6.7% and $108.2 million of our accounts receivable was included in the Securitization Program. Fair Value of Long-Term Debt The estimated fair values and carrying amounts of long-term debt, excluding finance leases, were as follows: June 30, 2023 December 31, 2022 (Thousands of Dollars) Fair value $ 3,250,699 $ 3,169,664 Carrying amount $ 3,260,205 $ 3,242,289 We have estimated the fair value of our publicly traded notes based upon quoted prices in active markets; therefore, we determined that the fair value of our publicly traded notes falls in Level 1 of the fair value hierarchy. With regard to our other debt, for which a quoted market price is not available, we have estimated the fair value using a discounted cash flow analysis using current incremental borrowing rates for similar types of borrowing arrangements and determined that the fair value falls in Level 2 of the fair value hierarchy. The carrying amount includes unamortized debt issuance costs.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIESWe have contingent liabilities resulting from various litigation, claims and commitments. We record accruals for loss contingencies when losses are considered probable and can be reasonably estimated. Legal fees associated with defending the Partnership in legal matters are expensed as incurred. We accrued $1.3 million and $0.3 million for contingent losses as of June 30, 2023 and December 31, 2022, respectively. The amount that will ultimately be paid related to such matters may differ from the recorded accruals, and the timing of such payments is uncertain. We evaluate each contingent loss at least quarterly, and more frequently as each matter progresses and develops over time, and we do not believe that the resolution of any particular claim or proceeding, or all matters in the aggregate, would have a material adverse effect on our results of operations, financial position or liquidity.

Temporary Equity Disclosure [Abstract]
SERIES D CUMULATIVE COVERTIBLE PREFERRED UNITS	SERIES D CUMULATIVE CONVERTIBLE PREFERRED UNITS Partial Redemptions On May 25, 2023 and June 29, 2023, NuStar Energy L.P. notified the holders of our Series D Preferred Units of our intent to exercise our right to redeem a portion of our outstanding Series D Preferred Units. The redemptions closed on June 30, 2023 and July 31, 2023, respectively, and were primarily funded with borrowings under our Revolving Credit Agreement, which had been partially paid down in the first quarter of 2023 with proceeds from the Sale-Leaseback Transaction. On the respective notification dates, those Series D Preferred Units became mandatorily redeemable; therefore, we reclassified those Series D Preferred Units from mezzanine equity to liability-classified “Mandatorily redeemable Series D preferred units” valued at the redemption price, excluding accrued distributions (Net Redemption Price). As of June 30, 2023, we presented the liability-classified Series D Preferred Units as non-current on our balance sheet as we had the intent and ability to refinance them on a long-term basis using our Revolving Credit Agreement. We recorded the difference between the carrying value of those Series D Preferred Units prior to reclassification and the Net Redemption Price as a deemed distribution, which reduced our common equity and reduced net income attributable to common units in the calculation of basic and diluted net income (loss) per common unit. At each closing, we accounted for the redemptions as extinguishments of debt. Distributions accrued for redeemed units from the notification dates to the redemption dates totaled $1.7 million for the three and six months ended June 30, 2023, and are reported in “Interest expense, net” on the condensed consolidated statements of comprehensive income. Information related to the redemptions is shown below (thousands of dollars, except date, unit and per unit data): June 30, 2023 Redemption July 31, 2023 Redemption Notification date May 25, 2023 June 29, 2023 Units redeemed 5,500,000 2,560,000 Redemption price per unit, including accrued distributions $ 31.88 $ 32.18 Redemption price, including accrued distributions $ 175,340 $ 82,381 Accrued distributions 825 1,152 Net Redemption Price $ 174,515 $ 81,229 Carrying value of units at notification date $ 152,467 $ 71,210 Net Redemption Price 174,515 81,229 Loss to common limited partners attributable to redemption $ (22,048) $ (10,019) Loss per common limited partner unit attributable to redemption $ (0.20) $ (0.09) Distributions We allocate net income to our Series D Preferred Units equal to the amount of distributions earned during the period. Distributions on the Series D Preferred Units are payable out of any legally available funds, accrue and are cumulative from the original issuance dates and are payable on the 15th day (or next business day) of each of March, June, September and December, beginning September 17, 2018, to holders of record on the first business day of each payment month. The distribution rates on the Series D Preferred Units are as follows: (i) 9.75% per annum ($0.619 per unit per distribution period) for the first two years; (ii) 10.75% per annum ($0.682 per unit per distribution period) for years three through five; and (iii) the greater of 13.75% per annum ($0.872 per unit per distribution period) or the distribution per common unit thereafter. While the Series D Preferred Units are outstanding, the Partnership will be prohibited from paying distributions on any junior securities, including the common units, unless full cumulative distributions on the Series D Preferred Units (and any parity securities) have been, or contemporaneously are being, paid or set aside for payment through the most recent Series D Preferred Unit distribution payment date. Any Series D Preferred Unit distributions in excess of $0.635 per unit may be paid, in the Partnership’s sole discretion, in additional Series D Preferred Units, with the remainder paid in cash. The distribution rate on our Series D Preferred Units increased on June 15, 2023, to the greater of 13.75% per annum ($0.872 per unit per distribution period) or the distribution per common unit. Total distribution excludes amounts reported in “Interest expense, net” as described above under “Partial Redemptions of Series D Preferred Units.” Distribution information on our Series D Preferred Units is as follows: Distribution Period Distribution Rate per Unit Total Distribution (Thousands of Dollars) June 15, 2023 - September 14, 2023 $ 0.872 $ 7,598 (a) March 15, 2023 - June 14, 2023 $ 0.682 $ 10,315 December 15, 2022 - March 14, 2023 $ 0.682 $ 11,148 June 15, 2022 - September 14, 2022 $ 0.682 $ 15,854 March 15, 2022 - June 14, 2022 $ 0.682 $ 15,854 December 15, 2021 - March 14, 2022 $ 0.682 $ 15,854 (a) Estimate is based on outstanding units after the July 31, 2023 redemption.

In July 2023, our board of directors declared distributions with respect to the Series A, B and C Preferred Units to be paid on September 15, 2023. Common Limited Partners We make quarterly distributions to common unitholders of 100% of our “Available Cash,” generally defined as cash receipts less cash disbursements, including distributions to our preferred units, and cash reserves established by the general partner, in its sole discretion. These quarterly distributions are declared and paid within 45 days subsequent to each quarter-end. The common unitholders receive a distribution each quarter as determined by the board of directors, subject to limitation by the distributions in arrears, if any, on our preferred units. In July 2023, our board of directors declared distributions with respect to our common units for the quarter ended June 30, 2023.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER COMMON UNIT	NET INCOME (LOSS) PER COMMON UNIT Basic and diluted net income (loss) per common unit is determined pursuant to the two-class method. Under this method, all earnings are allocated to our limited partners and participating securities based on their respective rights to receive distributions earned during the period. Participating securities include restricted units awarded under our long-term incentive plans and, beginning on June 15, 2023, the Series D Preferred Units. We compute basic net income (loss) per common unit by dividing net income (loss) attributable to common units by the weighted-average number of common units outstanding during the period. We compute diluted net income (loss) per common unit by dividing net income (loss) attributable to common units by the sum of (i) the weighted average number of common units outstanding during the period and (ii) the effect of dilutive potential common units outstanding during the period. Dilutive potential common units include the Series D Preferred Units. The Series D Preferred Units contain certain unitholder conversion and redemption features, and we use the if-converted method to calculate the dilutive effect of the conversion or redemption feature that is most advantageous to our Series D preferred unitholders. The effect of the assumed conversion or redemption of the Series D Preferred Units outstanding was antidilutive for each of the three and six months ended June 30, 2023 and 2022; therefore, we did not include such conversion in the computation of diluted net (loss) income per common unit. The following table details the calculation of basic and diluted net (loss) income per common unit: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (Thousands of Dollars, Except Unit and Per Unit Data) Net income $ 46,141 $ 59,199 $ 152,077 $ 71,511 Distributions to preferred limited partners (32,126) (31,523) (64,859) (62,615) Distributions to common limited partners (44,363) (44,128) (88,759) (88,293) Distribution equivalent rights to restricted units (667) (617) (1,339) (1,250) Distributions in excess of income $ (31,015) $ (17,069) $ (2,880) $ (80,647) Distributions to common limited partners $ 44,363 $ 44,128 $ 88,759 $ 88,293 Allocation of distributions in excess of income to common limited partners (31,015) (17,069) (2,880) (80,647) Series D Preferred Unit accretion (3,303) (4,734) (6,974) (9,315) Series D Preferred Unit redemption (32,067) — (32,067) — Net (loss) income attributable to common units $ (22,022) $ 22,325 $ 46,838 $ (1,669) Basic and diluted weighted-average common units outstanding 110,905,471 110,306,641 110,893,293 110,242,201 Basic and diluted net (loss) income per common unit $ (0.20) $ 0.20 $ 0.42 $ (0.02)

Earnings Per Share [Abstract]
Basic and Diluted Net Income (Loss) per Common Unit	Basic and diluted net income (loss) per common unit is determined pursuant to the two-class method. Under this method, all earnings are allocated to our limited partners and participating securities based on their respective rights to receive distributions earned during the period. Participating securities include restricted units awarded under our long-term incentive plans and, beginning on June 15, 2023, the Series D Preferred Units. We compute basic net income (loss) per common unit by dividing net income (loss) attributable to common units by the weighted-average number of common units outstanding during the period. We compute diluted net income (loss) per common unit by dividing net income (loss) attributable to common units by the sum of (i) the weighted average number of common units outstanding during the period and (ii) the effect of dilutive potential common units outstanding during the period. Dilutive potential common units include the Series D Preferred Units. The Series D Preferred Units contain certain unitholder conversion and redemption features, and we use the if-converted method to calculate the dilutive effect of the conversion or redemption feature that is most advantageous to our Series D preferred unitholders. The effect of the assumed conversion or redemption of the Series D Preferred Units outstanding was antidilutive for each of the three and six months ended June 30, 2023 and 2022; therefore, we did not include such conversion in the computation of diluted net (loss) income per common unit.
