ORGANIZATION AND BASIS OF PRESE

ORGANIZATION AND BASIS OF PRESENTATION	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	ORGANIZATION AND BASIS OF PRESENTATION USD Partners LP and its consolidated subsidiaries, collectively referred to herein as we, us, our, the Partnership and USDP, is a fee-based, growth-oriented master limited partnership formed in 2014 by US Development Group, LLC, or USD, through its wholly-owned subsidiary, USD Group LLC, or USDG. We were formed to acquire, develop and operate midstream infrastructure and complementary logistics solutions for crude oil, biofuels and other energy-related products. We generate substantially all of our operating cash flows from multi-year, take-or-pay contracts with primarily investment grade customers, including major integrated oil companies, refiners and marketers. Our network of crude oil terminals facilitate the transportation of heavy crude oil from Western Canada to key demand centers across North America. Our operations include railcar loading and unloading, storage and blending in onsite tanks, inbound and outbound pipeline connectivity, truck transloading, as well as other related logistics services. We also provide our customers with leased railcars and fleet services to facilitate the transportation of liquid hydrocarbons and biofuels by rail. We do not generally take ownership of the products that we handle, nor do we receive any payments from our customers based on the value of such products. We may, on occasion, enter into buy-sell arrangements in which we take temporary title to commodities while in our terminals. These arrangements are typically at fixed prices where we do not take commodity price exposure. A substantial amount of the operating cash flows related to the terminalling services that we provide are generated from take-or-pay contracts with minimum monthly commitment fees and, as a result, are not directly related to actual throughput volumes at our crude oil terminals. Throughput volumes at our terminals are primarily influenced by the difference in price between Western Canadian Select, or WCS, and other grades of crude oil, commonly referred to as spreads, rather than absolute price levels. WCS spreads are influenced by several market factors, including the availability of supplies relative to the level of demand from refiners and other end users, the price and availability of alternative grades of crude oil, the availability of takeaway capacity, as well as transportation costs from supply areas to demand centers. Recent Events In December 2019, a novel coronavirus disease (“COVID-19”) was reported and in March 2020, the World Health Organization declared that the spread of COVID-19 qualified as a global pandemic. The COVID-19 pandemic has adversely affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the pandemic has resulted in travel restrictions, business closures and the institution of quarantining and other restrictions on movement worldwide. In addition, in March 2020, members of the Organization of the Petroleum Exporting Countries (“OPEC”) and other oil producing countries (“OPEC+”) failed to agree on oil production levels, which led to a substantial decline in oil prices and an increasingly volatile market. In April 2020, even though OPEC+ announced that it had reached an agreement to cut production by 9.7 million barrels per day, or Mmbpd, oil prices did not meaningfully increase. Governments in the United States and Canada have limited movement of people and functioning of businesses in an effort to contain the spread of COVID-19. Mandatory and voluntary closures continue and their duration and impact remains unknown. As a result of these factors, there has been a significant reduction in demand for and prices of crude oil and natural gas liquids. Even when commodity prices have increased, they have remained highly volatile and at relatively low levels that have caused many oil and gas producers to suspend or reduce development programs. In July 2020, OPEC+ agreed to taper oil production cuts, which will scale back production cuts from 9.7 Mmbpd to 7.7 Mmbpd between August 2020 and January 2021. While COVID-19 is still a global pandemic, parts of the world have started to recover and some economies have started to reopen. However, certain jurisdictions that began re-opening have returned to restrictions in light of increased numbers of new COVID-19 cases. There still remains considerable uncertainty about the ultimate impact and duration of the pandemic and its effects on the global economy. As a result of the overall downturn in the crude market and the decline in the demand for petroleum products, we tested the goodwill associated with our Casper terminal for impairment as of March 31, 2020, which resulted in an impairment loss recognized for the nine months ended September 30, 2020. Refer to Note 8. Goodwill and Intangible Assets for further discussion of the impairment loss at the Casper terminal. If the current depressed pricing environment continues for an extended period, it may lead to a potential additional impairment of long-lived assets and customer demand for our services may also be negatively impacted. Any material non-payment or nonperformance by any of our key customers resulting from the current market conditions could have a material adverse effect on our business, financial condition, and results of operations in future periods. In addition, in March 2020, United States legislation referred to as the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), was signed into law. The CARES Act is an emergency economic stimulus package enacted in response to the coronavirus outbreak which, among other measures, contains numerous income tax provisions. Refer to Note 15. Income Taxes for further discussion of the impact of the CARES Act to our income taxes. Basis of Presentation Our accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim consolidated financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and disclosures required by GAAP for complete consolidated financial statements. In the opinion of our management, they contain all adjustments, including adjustments made associated with the provisions of the CARES Act discussed above, and consisting only of normal recurring adjustments, which our management considers necessary to present fairly our financial position as of September 30, 2020, our results of operations for the three and nine months ended September 30, 2020 and 2019, and our cash flows for the nine months ended September 30, 2020 and 2019. We derived our consolidated balance sheet as of December 31, 2019 from the audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. Our results of operations for the three and nine months ended September 30, 2020 and 2019 should not be taken as indicative of the results to be expected for the full year due to fluctuations in the supply of and demand for crude oil and biofuels, timing and completion of acquisitions, if any, changes in the fair market value of our derivative instruments and the impact of fluctuations in foreign currency exchange rates. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. Foreign Currency Translation We conduct a substantial portion of our operations in Canada, which we account for in the local currency, the Canadian dollar. We translate most Canadian dollar denominated balance sheet accounts into our reporting currency, the U.S. dollar, at the end of period exchange rate, while most accounts in our statement of operations are translated into our reporting currency based on the average exchange rate for each monthly period. Fluctuations in the exchange rate between the Canadian dollar and the U.S. dollar can create variability in the amounts we translate and report in U.S. dollars. Within these consolidated financial statements, we denote amounts denominated in Canadian dollars with “C$” immediately prior to the stated amount. US Development Group, LLC USD and its affiliates are engaged in designing, developing, owning and managing large-scale multi-modal logistics centers and energy-related infrastructure across North America. USD is the indirect owner of our general partner through its direct ownership of USDG and is currently owned by Energy Capital Partners, Goldman Sachs and certain of USD’s management team members.

Accounting Policies [Abstract]
RECENT ACCOUNTING PROUNOUNCEMENTS	RECENT ACCOUNTING PROUNOUNCEMENTS Recently Adopted Accounting Pronouncements Intangibles - Goodwill and Other (ASU 2017-04) In January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2017-04, or ASU 2017-04, which amends ASC Topic 350 to modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. Pursuant to the provisions of ASU 2017-04, an entity will no longer determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Rather, an entity will recognize an impairment loss for the amount by which the carrying amount of a reporting unit exceeds the reporting unit’s fair value. However, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit. The pronouncement is effective for fiscal years beginning after December 15, 2019, or for any interim impairment testing within those fiscal years and is required to be applied prospectively, with early adoption permitted. We adopted the provisions of ASU 2017-04 on January 1, 2020. In March 2020, we tested the goodwill associated with our Casper terminal for impairment due to there being circumstances that suggested the fair value of the Casper reporting unit was less than its carrying amount. The circumstances identified related to the overall downturn in the crude market and the decline in the demand for petroleum products, which could lead to delays or reductions of expected throughput levels and changes in expectations for current and future contracts at the Casper terminal. Refer to Note 1. Organization and Basis of Presentation — Recent Events for more information. This standard requires us to recognize an impairment loss for the amount by which the carrying amount of our Casper terminal exceeds the fair value of the terminal. Accordingly, we have recognized an impairment loss in our goodwill asset for the nine months ended September 30, 2020. Refer to Note 8. Goodwill and Intangible assets for more information. Recent Accounting Pronouncements Not Yet Adopted Income Taxes (ASU 2019-12) In December 2019, the FASB issued Accounting Standards Update No. 2019-12, or ASU 2019-12, which amends ASC Topic 740 by removing certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. In addition, under the provisions of ASU 2019-12, single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER LIMITED PARTNER INTEREST	NET INCOME (LOSS) PER LIMITED PARTNER INTEREST We allocate our net income or loss among our general partner and limited partners using the two-class method in accordance with applicable authoritative accounting guidance. Under the two-class method, we allocate our net income or loss and any net income or loss in excess of distributions to our limited partners, our general partner and the holder of the incentive distribution rights, or IDRs, according to the distribution formula for available cash as set forth in our partnership agreement. We allocate any distributions in excess of earnings for the period to our limited partners and general partner based on their respective proportionate ownership interests in us, as set forth in our partnership agreement after taking into account distributions to be paid with respect to the IDRs. The formula for distributing available cash as set forth in our partnership agreement is as follows: Distribution Targets Portion of Quarterly Percentage Distributed to Limited Partners Percentage Distributed to General Partner (including IDRs) (1) Minimum Quarterly Distribution Up to $0.2875 98% 2% First Target Distribution > $0.2875 to $0.330625 98% 2% Second Target Distribution > $0.330625 to $0.359375 85% 15% Third Target Distribution > $0.359375 to $0.431250 75% 25% Thereafter Amounts above $0.431250 50% 50% (1) Calculated as if our general partner holds the original 2% general partner interest in us, which is currently at 1.7%.

Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES Disaggregated Revenues We manage our business in two reportable segments: Terminalling services and Fleet services. Our segments offer different services and are managed accordingly. Our chief operating decision maker, or CODM, regularly reviews financial information about both segments in order to allocate resources and evaluate performance. As such, we have concluded that disaggregating revenue by reporting segments appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Refer to Note 14. Segment Reporting for our disaggregated revenues by segment. Additionally, the below tables summarize the geographic data for our revenues: Three Months Ended September 30, 2020 U.S. Canada Total (in thousands) Third party $ 8,799 $ 20,221 $ 29,020 Related party $ 2,317 $ — $ 2,317 Three Months Ended September 30, 2019 U.S. Canada Total (in thousands) Third party $ 7,963 $ 16,068 $ 24,031 Related party $ 2,320 $ 3,543 $ 5,863 Nine Months Ended September 30, 2020 U.S. Canada Total (in thousands) Third party $ 22,501 $ 53,850 $ 76,351 Related party $ 6,737 $ 5,891 $ 12,628 Nine Months Ended September 30, 2019 U.S. Canada Total (in thousands) Third party $ 25,405 $ 39,163 $ 64,568 Related party $ 6,902 $ 12,607 $ 19,509 Remaining Performance Obligations The transaction price allocated to the remaining performance obligations associated with our terminalling and fleet services agreements as of September 30, 2020 are as follows for the periods indicated: For the three months ending December 31, 2020 2021 2022 2023 Thereafter Total (in thousands) Terminalling Services (1) (2) (3) $ 25,364 $ 95,878 $ 72,203 $ 36,613 $ 146,460 $ 376,518 Fleet Services 257 1,016 1,269 38 8 2,588 Total $ 25,621 $ 96,894 $ 73,472 $ 36,651 $ 146,468 $ 379,106 (1) A significant portion of our terminalling services agreements are denominated in Canadian dollars. We have converted the remaining performance obligations associated with these Canadian dollar-denominated contracts using the year-to-date average exchange rate of 0.7392 U.S. dollars per each Canadian dollar at September 30, 2020. (2) Includes fixed monthly minimum commitment fees per contracts and excludes constrained estimates of variable consideration for rate-escalations associated with an index, such as the consumer price index, as well as any incremental revenue associated with volume activity above the minimum volumes set forth within the contracts. Also excludes estimated constrained variable consideration included in certain of our terminalling services agreements that is based on crude oil pricing index differentials. (3) Assumes USD’s Diluent Recovery Unit project goes into service in the second half of 2021, which will result in certain terminalling services agreements of our Hardisty terminal being automatically extended through mid-2031 and certain agreements at our Stroud terminal having a termination right in June 2022. We have applied the practical expedient that allows us to exclude disclosure of performance obligations that are part of a contract that has an expected duration of one year or less. Contract Assets Our contract assets represent cumulative revenue that has been recognized in advance of billing the customer due to tiered billing provisions. In such arrangements, revenue is recognized using a blended rate based on the billing tiers of the agreement, as the services are consistently provided throughout the duration of the contractual arrangement. We had the following amounts outstanding associated with our contract assets on our consolidated balance sheets in the financial statement line items presented below in the following table for the indicated periods: September 30, 2020 December 31, 2019 (in thousands) Other current assets $ 1,044 $ 171 Other current assets — related party $ — $ 264 Deferred Revenue Our deferred revenue is a form of a contract liability and consists of amounts collected in advance from customers associated with their terminalling and fleet services agreements and deferred revenues associated with make-up rights, which will be recognized as revenue when earned pursuant to the terms of our contractual arrangements. We currently recognize substantially all of the amounts we receive for minimum volume commitments as revenue when collected, since breakage associated with these make-up rights is currently 100% based on our experience and expectations around usage of these options. Accordingly, we had no deferred revenues at September 30, 2020 for estimated breakage associated with the make-up rights options we granted to our customers. There were $1.1 million of deferred revenues associated with make-up rights at December 31, 2019. We also have deferred revenue that represents cumulative revenue that has been deferred due to tiered billing provisions. In such arrangements, revenue is recognized using a blended rate based on the billing tiers of the agreement, as the services are consistently provided throughout the duration of the contractual arrangement, which we included in “ Other non-current liabilities ” on our consolidated balance sheets. The following table presents the amounts outstanding on our consolidated balance sheets and changes associated with the balance of our deferred revenue for the nine months ended September 30, 2020: December 31, 2019 Cash Additions for Customer Prepayments Revenue Recognized September 30, 2020 (in thousands) Deferred revenue $ 6,104 $ 5,607 $ (6,104) $ 5,607 Deferred revenue — related party (1) $ 1,072 $ — $ (1,072) $ — Other non-current liabilities (2) $ 3,391 $ 5,181 $ — $ 8,572 (1) Includes deferred revenue associated with customer prepayments from related parties. Refer to Note 12. Transactions with Related Parties for additional discussion of deferred revenues associated with related parties. Excludes deferred revenue from related parties associated with our fleet leases discussed below. (2) Includes cumulative revenue that has been deferred due to tiered billing provisions included in certain of our Canadian dollar-denominated contracts, as discussed above. As such, the change in “Other non-current liabilities” presented has been reduced by approximately $88 thousand due to the impact of the change in the end of period exchange rate between December 31, 2019 and September 30, 2020. Deferred Revenue — Fleet Leases Our deferred revenue also includes advance payments from customers of our Fleet services business, which will be recognized as Fleet leases revenue when earned pursuant to the terms of our contractual arrangements. We have included $0.4 million at each of September 30, 2020 and December 31, 2019 in “ Deferred revenue — related party ” on our consolidated balance sheets associated with customer prepayments for our fleet lease agreements. Refer to Note 7. Leases for additional discussion of our lease revenues.

These amounts represent property that has not been placed into productive service as of the respective consolidated balance sheet date. We had no capitalized interest costs for the three and nine months ended September 30, 2020, and $170 thousand and $439 thousand for the three and nine months ended September 30, 2019, respectively Depreciation expense associated with property and equipment totaled $2.3 million and $2.1 million for the three months ended September 30, 2020 and 2019, respectively, and $6.6 million and $5.9 million for the nine months ended September 30, 2020 and 2019, respectively. Our depreciation expense reflects a reduction to our asset retirement obligation, or ARO, of $0.2 million and $0.6 million for the nine months ended September 30, 2020 and 2019, respectively, due to refinement of our estimates. We had no change in our estimates for the three months ended September 30, 2020 and 2019. The ARO was associated with restoration of the property at our San Antonio facility. All remediation activities associated with the ARO are now deemed complete and this position has not been disputed by the property owner. There is no remaining balance related to ARO on our consolidated balance sheet at September 30, 2020.

GOODWILL AND INTANGIBLE ASSETS

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Goodwill Goodwill represents the excess of the purchase price of an entity over the estimated fair value of the assets acquired and liabilities assumed. Our goodwill originated from our acquisition of the Casper terminal, which is included in our Terminalling services segment. In March 2020, we tested the goodwill associated with our Casper terminal for impairment due to the overall downturn in the crude market and the decline in the demand for petroleum products, which could lead to delays or reductions of expected throughput levels and changes in expectations for current and future contracts at the Casper terminal. Refer to Note 1. Organization and Basis of Presentation — Current Events for more information. The critical assumptions used in our analysis include the following: 1) a weighted average cost of capital of 12%; 2) a capital structure consisting of approximately 65% debt and 35% equity based on the capital structure of market participants; 3) a range of EBITDA multiples derived from equity prices of public companies with similar operating and investment characteristics, from 7.25x to 8.25x; 4) a range of EBITDA multiples for transactions based on actual sales and purchases of comparable businesses, from 8.0x to 9.0x; and 5) a range of incremental volumes expected at our Casper terminal of approximately 4,000 to 25,000 bpd for terminalling and storage services resulting from the anticipated successful completion of the Enbridge DRA project in the second half of 2020. We measured the fair value of our Casper terminal reporting unit by using an income analysis, market analysis and transaction analysis with weightings of 50%, 25% and 25%, respectively. Our estimate of fair value required us to use significant unobservable inputs representative of a Level 3 fair value measurement, including assumptions related to the future performance of our Casper terminal. We determined that the carrying amount of our Casper terminal reporting unit exceeded its fair value at March 31, 2020. Accordingly, we recognized an impairment loss of $33.6 million in our goodwill asset and included this charge in “Goodwill impairment loss” within our consolidated statement of operations for the nine months ended September 30, 2020. For additional information see Note 2. Recent Accounting Pronouncements . At September 30, 2020, we had no goodwill balance in our consolidated balance sheet. Intangible Assets The composition, gross carrying amount and accumulated amortization of our identifiable intangible assets are as follows as of the dates indicated: September 30, 2020 December 31, 2019 (in thousands) Carrying amount: Customer service agreements $ 125,960 $ 125,960 Other 106 106 Total carrying amount 126,066 126,066 Accumulated amortization: Customer service agreements (61,371) (51,923) Other (51) (44) Total accumulated amortization (61,422) (51,967) Total intangible assets, net $ 64,644 $ 74,099 Amortization expense associated with intangible assets totaled $3.2 million for the three months ended September 30, 2020 and 2019, and $9.5 million for the nine months ended September 30, 2020 and 2019. We determined the overall downturn in the crude market and the decline in the demand for petroleum products, which could lead to delays or reduction of expected throughput levels and changes in expectations for current and future contracts in our terminalling services at the Casper terminal, was an event that required us to evaluate our Casper terminal asset group for impairment. We measured the fair value of our Casper terminal assets at March 31, 2020, by using projections of the undiscounted cash flows expected to be derived from the operation and disposition of the Casper terminal asset. The critical assumptions underlying our projections included the following: 1) a range of incremental volumes expected at our Casper terminal of approximately 4,000 to 25,000 bpd for terminalling and storage services resulting from the anticipated successful completion of the Enbridge DRA project in the second half of 2020; 2) expected volumes for our blended services business for distribution to local refiners; 3) a 15 year remaining useful life of the primary asset, represented by our property and equipment of the Casper terminal asset group; and 4) a residual value of 8.0x projected cash flows for the Casper terminal at the end of the 15 year remaining life of the primary asset. Our projections of the undiscounted cash flows expected to be derived from the operation and disposition of the Casper terminal asset group exceeded the carrying amount of the asset group as of March 31, 2020, the date of our evaluation, indicating cash flows were expected to be sufficient to recover the carrying amount of the Casper terminal asset group. Accordingly, we did not recognize any impairment of our asset. We have not observed any events or circumstances subsequent to our analysis that would suggest the fair value of our Casper terminal is below its carrying amount as of September 30, 2020.

DEBT	DEBT In November 2018, we amended and restated our senior secured credit agreement, which we originally established at the time of our initial public offering in October 2014. We refer to the amended and restated senior secured credit agreement executed in November 2018 as the Credit Agreement and the original senior secured credit agreement as the Previous Credit Agreement. Our Credit Agreement is a $385 million revolving credit facility (subject to limits set forth therein) with Citibank, N.A., as administrative agent, and a syndicate of lenders. Our Credit Agreement amends and restates in its entirety our Previous Credit Agreement. Our Credit Agreement is a four year committed facility that initially matures on November 2, 2022. Our Credit Agreement provides us with the ability to request two one-year maturity date extensions, subject to the satisfaction of certain conditions, and allows us the option to increase the maximum amount of credit available up to a total facility size of $500 million, subject to receiving increased commitments from lenders and satisfaction of certain conditions. Our Credit Agreement and any issuances of letters of credit are available for working capital, capital expenditures, general partnership purposes and continue the indebtedness outstanding under the Previous Credit Agreement. The Credit Agreement includes an aggregate $20 million sublimit for standby letters of credit and a $20 million sublimit for swingline loans. Obligations under the Credit Agreement are guaranteed by our restricted subsidiaries (as such term is defined therein) and are secured by a first priority lien on our assets and those of our restricted subsidiaries, other than certain excluded assets. Our long-term debt balances included the following components as of the specified dates: September 30, 2020 December 31, 2019 (in thousands) Revolving Credit Facility $ 209,000 $ 220,000 Less: Deferred financing costs, net (1,727) (2,349) Total long-term debt, net $ 207,273 $ 217,651 We determined the capacity available to us under the terms of our Credit Agreement was as follows as of the specified dates: September 30, 2020 December 31, 2019 (in millions) Aggregate borrowing capacity under Credit Agreement $ 385.0 $ 385.0 Less: Revolving Credit Facility amounts outstanding 209.0 220.0 Available under the Credit Agreement based on capacity $ 176.0 $ 165.0 Available under the Credit Agreement based on covenants (1) $ 37.2 $ 28.8 (1) Pursuant to the terms of our Credit Agreement, our borrowing capacity, currently, is limited to 4.5 times our trailing 12-month consolidated EBITDA, which equates to $37.2 million and $28.8 million of borrowing capacity available at September 30, 2020 and December 31, 2019, respectively. The weighted average interest rate on our outstanding indebtedness was 2.91% and 4.24% at September 30, 2020 and December 31, 2019, respectively, without consideration to the effect of our derivative contracts. In addition to the interest we incur on our outstanding indebtedness, we pay commitment fees of 0.50% on unused commitments, which rate will vary based on our consolidated net leverage ratio, as defined in our Credit Agreement. At September 30, 2020, we were in compliance with the covenants set forth in our Credit Agreement. Interest expense associated with our outstanding indebtedness was as follows for the specified periods: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (in thousands) Interest expense on the Credit Agreement $ 1,837 $ 2,967 $ 6,418 $ 8,748 Capitalized interest on construction in progress — (170) — (439) Amortization of deferred financing costs 208 208 622 865 Total interest expense $ 2,045 $ 3,005 $ 7,040 $ 9,174

Organization, Consolidation and Presentation of Financial Statements [Abstract]
COLLABORATIVE ARRANGEMENT	COLLABORATIVE ARRANGEMENTWe entered into a facilities connection agreement in 2014 with Gibson under which Gibson developed, constructed and operates a pipeline and related facilities connected to our Hardisty terminal. Gibson’s storage terminal is the exclusive means by which our Hardisty terminal receives crude oil. Subject to certain limited exceptions regarding manifest train facilities, our Hardisty terminal is the exclusive means by which crude oil from Gibson’s Hardisty storage terminal may be transported by rail. We remit pipeline fees to Gibson for the transportation of crude oil to our Hardisty terminal based on a predetermined formula. Pursuant to our arrangement with Gibson, we incurred pipeline fees of $5.9 million and $5.4 million for the three months ended September 30, 2020 and 2019, and $17.7 million and $15.4 million for the nine months ended September 30, 2020 and 2019, respectively, which are presented as “Pipeline fees” in our consolidated statements of operations. We have included a liability related to this agreement in “Other Current Liabilities” on our consolidated balance sheets of $3.1 million and $1.2 million at September 30, 2020 and December 31, 2019.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
NONCONSOLIDATED VARIABLE INTEREST ENTITIES	NONCONSOLIDATED VARIABLE INTEREST ENTITIES We have entered into purchase, assignment and assumption agreements to assign payment and performance obligations for certain operating lease agreements with lessors, as well as customer fleet service payments related to these operating leases, with unconsolidated entities in which we have variable interests. These variable interest entities, or VIEs, include LRT Logistics Funding LLC, USD Fleet Funding LLC, USD Fleet Funding Canada Inc., and USD Logistics Funding Canada Inc. We treat these entities as variable interests under the applicable accounting guidance due to their having an insufficient amount of equity invested at risk to finance their activities without additional subordinated financial support. We are not the primary beneficiary of the VIEs, as we do not have the power to direct the activities that most significantly affect the economic performance of the VIEs, nor do we have the power to remove the managing member under the terms of the VIEs’ limited liability company agreements. Accordingly, we do not consolidate the results of the VIEs in our consolidated financial statements. The following table summarizes the total assets and liabilities between us and the VIEs as reflected in our consolidated balance sheets at September 30, 2020 and December 31, 2019, as well as our maximum exposure to losses from entities in which we have a variable interest, but are not the primary beneficiary. Generally, our maximum exposure to losses is limited to amounts receivable for services we provided, reduced by any deferred revenues.

During the quarter ended September 30, 2020, we provided no explicit or implicit financial or other support to these VIEs that were not previously contractually required.

Related Party Transactions [Abstract]
TRANSACTIONS WITH RELATED PARTIES	TRANSACTIONS WITH RELATED PARTIES Nature of Relationship with Related Parties USD is engaged in designing, developing, owning and managing large-scale multi-modal logistics centers and other energy-related infrastructure across North America. USD is also the sole owner of USDG and the ultimate parent of our general partner. USD is owned by Energy Capital Partners, Goldman Sachs and certain members of its management. USDG is the sole owner of our general partner and at September 30, 2020, owns 11,557,090 of our common units representing a 42.3% limited partner interest in us. As of September 30, 2020, a value of up to $10.0 million of these common units were pledged as collateral under USDG’s letter of credit facility. USDG also provides us with general and administrative support services necessary for the operation and management of our business. USD Partners GP LLC, our general partner, currently owns all 461,136 of our general partner units representing a 1.7% general partner interest in us, as well as all of our incentive distribution rights. Pursuant to our partnership agreement, our general partner is responsible for our overall governance and operations. However, our general partner has no obligation to, does not intend to and has not implied that it would, provide financial support to or fund cash flow deficits of the Partnership. USD Marketing LLC, or USDM, is a wholly-owned subsidiary of USDG organized to promote contracting for services provided by our terminals and to facilitate the marketing of customer products. USD Terminals Canada II ULC, or USDTC II, is an indirect, wholly-owned Canadian subsidiary of USDG, organized for the purposes of pursuing expansion and other development opportunities associated with our Hardisty Terminal, pursuant to the Development Rights and Cooperation agreement between our wholly-owned subsidiary USD Terminals Canada ULC, or USDTC, and USDG. USDTC owns the legacy crude oil loading facility we refer to as the Hardisty terminal. USDTC II completed construction of the Hardisty South expansion (“Hardisty South”) which commenced operations in January 2019. Hardisty South, which is owned and operated by USDTC II, added one and one-half 120-railcar unit trains of transloading capacity per day, or approximately 112,500 barrels per day, of takeaway capacity to the terminal by modifying the existing loading rack and building additional infrastructure and trackage. Omnibus Agreement We are party to an omnibus agreement with USD, USDG and certain of their subsidiaries, or Omnibus Agreement, including our general partner, pursuant to which we obtain and make payments for specified services provided to us and for out-of-pocket costs incurred on our behalf. We pay USDG, in equal monthly installments, the annual amount USDG estimates will be payable by us during the calendar year for providing services for our benefit. The Omnibus Agreement provides that this amount may be adjusted annually to reflect, among other things, changes in the scope of the general and administrative services provided to us due to a contribution, acquisition or disposition of assets by us or our subsidiaries, or for changes in any law, rule or regulation applicable to us, which affects the cost of providing the general and administrative services. We also reimburse USDG for any out-of-pocket costs and expenses incurred on our behalf in providing general and administrative services to us. This reimbursement is in addition to the amounts we pay to reimburse our general partner and its affiliates for certain costs and expenses incurred on our behalf for managing our business and operations, as required by our partnership agreement. The total amounts charged to us under the Omnibus Agreement for the three months ended September 30, 2020 and 2019 was $1.7 million and $1.4 million, respectively, and for the nine months ended September 30, 2020 and 2019 was $5.6 million and $6.1 million, respectively, which amounts are included in “ Selling, general and administrative — related part y” in our consolidated statements of operations. We had a payable balance of $0.3 million and $0.4 million with respect to these costs at September 30, 2020 and December 31, 2019, respectively included in “ Accounts payable and accrued expenses — related party ” in our consolidated balance sheets. Marketing Services Agreement In connection with our purchase of the Stroud terminal, we entered into a Marketing Services Agreement with USDM, in May 2017, whereby we granted USDM the right to market the capacity at the Stroud terminal in excess of the original capacity of our initial customer in exchange for a nominal per barrel fee. USDM is obligated to fund any related capital costs associated with increasing the throughput or efficiency of the terminal to handle additional throughput. Upon expiration of our contract with the initial Stroud customer in June 2020, the same marketing rights now apply to all throughput at the Stroud terminal in excess of the throughput necessary for the Stroud terminal to generate Adjusted EBITDA that is at least equal to the average monthly Adjusted EBITDA derived from the initial Stroud customer during the 12 months prior to expiration. We also granted USDG the right to develop other projects at the Stroud terminal in exchange for the payment to us of market-based compensation for the use of our property for such development projects. Any such development projects would be wholly-owned by USDG and would be subject to our existing right of first offer with respect to midstream projects developed by USDG. Payments made under the Marketing Services Agreement during the periods presented in this Report are discussed below under the heading “ Related Party Revenue and Deferred Revenue. ” Hardisty Terminal Services Agreement We entered into a terminal services agreement with USDTC II during the third quarter of 2019, whereby Hardisty South will provide terminalling services for a third-party customer of our Hardisty terminal for contracted capacity that exceeds the transloading capacity currently available. We incurred $2.1 million and $6.2 million of expenses pursuant to the arrangement for the three and nine months ended September 30, 2020 and $2.5 million for the three and nine months ended September 30, 2019, which amounts are included in “ Operating and maintenance expense — related party ” in our consolidated statements of operations. These costs represent the same rate, on a per barrel basis, that we received as revenue from our third-party customer, which is included in “ Terminalling Services ” revenue in our consolidated statements of operations. Additionally, in conjunction with this agreement, we recorded a contract asset of $1.2 million at September 30, 2020 on our consolidated balance sheet in “ Other non-current assets — related party ”, representing long-term prepaid expense associated with this agreement due to tiered billing provisions in the related terminalling services agreements. We had no recorded asset at December 31, 2019, associated with this agreement. Hardisty Shared Facilities Agreement USDTC facilitates the provision of services on behalf of USDTC II pursuant to the terms of a shared facilities agreement, which includes all subcontracted railcar loading, operating, maintenance, pipeline and management services for the entire Hardisty terminal, including Hardisty South owned by USDTC II. USDTC passes through a proportionate amount of the cost of such services to USDTC II. Our financial statements only reflect the cost incurred by USDTC. Related Party Revenue and Deferred Revenue We have agreements to provide terminalling and fleet services for USDM with respect to our Hardisty terminal and terminalling services with respect to our Stroud terminal, which also include reimbursement to us for certain out-of-pocket expenses we incur. USDM assumed the rights and obligations for terminalling capacity at our Hardisty terminal from another customer in June 2017 to facilitate the origination of crude oil barrels by the Stroud customer from our Hardisty terminal for delivery to the Stroud terminal. As a result of USDM assuming these rights and obligations and in order to accommodate the needs of the Stroud customer, the contracted term for the capacity held by USDM at our Hardisty terminal was extended from June 30, 2019 to June 30, 2020. The terms and conditions of these agreements were similar to the terms and conditions of agreements we have with other parties at the Hardisty terminal that are not related to us. USDM’s agreement with the third party customer was renewed and extended, effective July 1, 2020, and USDM subsequently assigned its terminalling services agreement with the third party customer directly to us and is therefore no longer a customer at our Hardisty terminal. USDM controlled approximately 25% of the available monthly capacity of the Hardisty terminal through June 30, 2020. In connection with our purchase of the Stroud terminal, we also entered into a Marketing Services Agreement with USDM, as discussed above. Pursuant to the terms of the agreement, we receive a fixed amount per barrel from USDM in exchange for marketing the additional capacity available at the Stroud terminal. We also received revenue for providing additional terminalling services at our Hardisty terminal to USDM pursuant to the terms of its existing agreements with us. Additionally, effective January 2019, we entered into a six month terminalling services agreement with USDM at our Casper terminal to maximize utilization of available terminalling and storage capacity by offering these services to customers on an uncommitted basis at current market rates. This agreement automatically renews for successive periods of six months on an evergreen basis unless otherwise canceled by either party. We include amounts received pursuant to these arrangements as revenue in the table below under “ Terminalling services — related party ” in our consolidated statements of operations. Additionally, we received revenue from USDM for the lease of 200 railcars pursuant to the terms of an existing agreement with us, which is included in the table below under “ Fleet leases — related party ” and “ Fleet services — related party ” and in our consolidated statements of operations. Our related party revenues from USD and affiliates are presented below in the following table for the indicated periods: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (in thousands) Terminalling services — related party $ 1,041 $ 4,459 $ 8,929 $ 15,622 Fleet leases — related party 984 984 2,951 2,951 Fleet services — related party 227 227 682 682 Freight and other reimbursables — related party 65 193 66 254 $ 2,317 $ 5,863 $ 12,628 $ 19,509 We had the following amounts outstanding with USD and affiliates on our consolidated balance sheets as presented below in the following table for the indicated periods: September 30, 2020 December 31, 2019 (in thousands) Accounts receivable — related party $ 2,508 $ 1,778 Accounts payable and accrued expenses — related party (1) $ 64 $ 87 Other current and non-current assets — related party (2) $ 1,262 $ 358 Deferred revenue — related party (3) $ 410 $ 1,482 (1) Includes amounts payable to a related party pursuant to the Hardisty Terminal Services Agreement, discussed above, as well as other accounts payable related party amounts associated with our terminalling services business.

SEGMENT REPORTING

SEGMENT REPORTING	9 Months Ended
	Sep. 30, 2020
Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING We manage our business in two reportable segments: Terminalling services and Fleet services. The Terminalling services segment charges minimum monthly commitment fees under multi-year take-or-pay contracts to load and unload various grades of crude oil into and from railcars, as well as fixed fees per gallon to transload ethanol from railcars, including related logistics services. We also facilitate rail-to-pipeline shipments of crude oil. Our Terminalling services segment also charges minimum monthly fees to store crude oil in tanks that are leased to our customers. The Fleet services segment provides customers with railcars and fleet services related to the transportation of liquid hydrocarbons and biofuels under multi-year, take-or-pay contracts. Corporate activities are not considered a reportable segment, but are included to present shared services and financing activities which are not allocated to our established reporting segments. Our segments offer different services and are managed accordingly. Our chief operating decision maker, or CODM, regularly reviews financial information about both segments in order to allocate resources and evaluate performance. Our CODM assesses segment performance based on the cash flows produced by our established reporting segments using Segment Adjusted EBITDA. Segment Adjusted EBITDA is a measure calculated in accordance with GAAP. We define Segment Adjusted EBITDA as “Net income (loss)” of each segment adjusted for depreciation and amortization, interest, income taxes, changes in contract assets and liabilities, deferred revenues, foreign currency transaction gains and losses and other items which do not affect the underlying cash flows produced by our businesses. As such, we have concluded that disaggregating revenue by reporting segments appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES CARES Act On March 27, 2020, the CARES Act was signed into law. The CARES Act is an emergency economic stimulus package enacted in response to the coronavirus outbreak which, among other measures, contains numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for tax years ending before the date of enactment. For us, the most significant change included in the CARES Act was the impact to U.S. net operating loss carryback provisions. U.S. net operating losses incurred in tax years 2018, 2019, and 2020 can now be carried back to the preceding five tax years and may be used to fully offset taxable income (i.e. they are not subject to the 80 percent net income offset limitation of Section 172 of the U.S. Tax Code). As a result of these CARES Act changes, for the three and nine months ended September 30, 2020 we recognized a current tax benefit of $3 thousand and $533 thousand, respectively, for a claimable tax refund by carrying back U.S. net operating losses incurred in 2018, 2019, and the first nine months of 2020. We also recognized a one-time deferred tax expense of $46 thousand in the first quarter of 2020 due to the net effect of utilizing all U.S. net operating loss deferred tax assets and releasing the corresponding U.S. valuation allowance as of December 31, 2019. We expect to recognize an additional tax benefit in 2020 due to anticipated tax losses. The tax impacts of the CARES Act were computed with the best available information, and will be adjusted after the 2020 U.S. tax return is finalized. However, we do not expect these adjustments to result in a material change to the tax provision in future periods. Goodwill Impairment Tax Impact For the nine months ended September 30, 2020, we recognized a loss before income taxes of $27.0 million due primarily to a goodwill impairment loss recognized during the first quarter of 2020 associated with our Casper terminal included in our terminalling services segment. Refer to Note 8. Goodwill and Intangible Assets for more information. Our tax provision for the nine months ended September 30, 2020 was not impacted by the goodwill impairment loss as our terminalling services activities in the U.S. are treated as a partnership for U.S. federal and most state income tax purposes, with each partner being separately taxed on their share of our taxable income. Refer to Note 19. Supplemental Cash Flow Information for information regarding amounts paid for income taxes.

DERIVATIVE FINANCIAL INSTRUMENT

DERIVATIVE FINANCIAL INSTRUMENTS	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Our net income, or loss, and cash flows are subject to fluctuations resulting from changes in interest rates on our variable rate debt obligations and from changes in foreign currency exchange rates, particularly with respect to the U.S. dollar and the Canadian dollar. In limited circumstances, we may also hold long positions in the commodities we handle on behalf of our customers, which exposes us to commodity price risk. We use derivative financial instruments, including futures, forwards, swaps, options and other financial instruments with similar characteristics, to manage the risks associated with market fluctuations in interest rates, foreign currency exchange rates and commodity prices, as well as to reduce volatility in our cash flows. We have not historically designated, nor do we expect to designate, our derivative financial instruments as hedges of the underlying risk exposure. All of our financial instruments are employed in connection with an underlying asset, liability and/or forecasted transaction and are not entered into for speculative purposes. Interest Rate Derivatives We use interest rate derivative financial instruments to partially mitigate our exposure to interest rate fluctuations on our variable rate debt. Under our Credit Agreement, one-month LIBOR is used as the index rate for the interest we are charged on amounts borrowed under our Revolving Credit Facility. In November 2017, we entered into a five-year interest rate collar contract with a $100 million notional value. The collar established a range where we paid the counterparty if the one-month Overnight Index Swap, or OIS, fell below the established floor rate of 1.70%, and the counterparty paid us if the one-month OIS rate exceeded the established ceiling rate of 2.50%. The collar settled monthly through the termination date. No payments or receipts were exchanged on the interest rate collar contracts unless interest rates rose above or fell below the predetermined ceiling or floor rate. Prior to February 2019, our interest rate collar contract discussed above was based on one-month LIBOR, which is being phased out by financial institutions in the United States. In September 2020, we terminated our existing interest rate collar discussed above and simultaneously entered into a new interest rate swap that was made effective as of August 2020. In lieu of settling the liability value of the existing interest rate collar agreement of $3.5 million that existed at the time the agreement was terminated, the value of the liability was rolled into the fixed rate of the new interest rate swap agreement. The new interest rate swap is a five-year contract with a $150 million notional value that fixes our one-month LIBOR to 0.84% for the notional value of the swap agreement instead of the variable rate that we pay under our Credit Agreement. The swap settles monthly through the termination date in August 2025. Derivative Positions We record all of our derivative financial instruments at their fair values in the line items specified below within our consolidated balance sheets, the amounts of which were as follows at the dates indicated: September 30, 2020 December 31, 2019 (in thousands) Other current liabilities $ (1,060) $ (139) Other non-current liabilities (3,539) (687) $ (4,599) $ (826) We have not designated our derivative financial instruments as hedges of our interest rate exposure. As a result, changes in the fair value of these derivatives are recorded as “Loss associated with derivative instruments” in our consolidated statements of operations. The gains or losses associated with changes in the fair value of our derivative contracts do not affect our cash flows until the underlying contract is settled by making or receiving a payment to or from the counterparty.

PARTNERS' CAPITAL

PARTNERS' CAPITAL	9 Months Ended

Equity [Abstract]
PARTNERS' CAPITAL	PARTNERS’ CAPITAL Our common units represent and subordinated units represented limited partner interests in us. The holders of common units are and subordinated units were entitled to participate in partnership distributions and to exercise the rights and privileges available to limited partners under our partnership agreement. In February 2019, pursuant to the terms set forth in our partnership agreement, the fourth and final vesting tranche of 38,750 Class A units vested and was converted into our common units. We determined that each vested Class A unit would receive one common unit at conversion based upon our distributions paid for the four preceding quarters. As a result, the final tranche of 38,750 Class A units were converted into 38,750 common units and no Class A units remain outstanding at September 30, 2020. Our Class A units were limited partner interests in us that entitled the holders to nonforfeitable distributions that were equivalent to the distributions paid with respect to our common units (excluding any arrearages of unpaid minimum quarterly distributions from prior quarters) and, as a result, were considered participating securities. Our Class A units did not have voting rights and vested in four equal annual installments over the four years following the consummation of our initial public offering, or IPO, only if we grew our annualized distributions each year. If we did not achieve positive distribution growth in any of those years, the Class A units that would otherwise vest for that year would be forfeited. The Class A units contained a conversion feature, which, upon vesting, provided for the conversion of the Class A units into common units based on a conversion factor that was tied to the level of our distribution growth for the applicable year. The conversion factor was 1.00 for the first vesting tranche, 1.50 for the second vesting tranche, 1.00 for the third vesting tranche and 1.00 for the fourth vesting tranche. All of our subordinated units converted into common units on a one-for-one basis in separate sequential tranches. Each tranche was comprised of 20.0% of the subordinated units issued in conjunction with our IPO. Each separate tranche was eligible to convert on or after December 31, 2015 (but no more frequently than once in any twelve-month period), provided on such date: (i) distributions of available cash from operating surplus on each of the outstanding common units, Class A units, subordinated units and general partner units equaled or exceeded $1.15 per unit (the annualized minimum quarterly distribution) for the four quarter period immediately preceding that date; (ii) the adjusted operating surplus generated during the four quarter period immediately preceding that date equaled or exceeded the sum of $1.15 per unit (the annualized minimum quarterly distribution) on all of the common units, Class A units, subordinated units and general partner units outstanding during that period on a fully diluted basis; and (iii) there were no arrearages in the payment of the minimum quarterly distribution on our common units. For each successive tranche, the four quarter period specified in clauses (i) and (ii) above must have commenced after the four quarter period applicable to any prior tranche of subordinated units. In February 2020, pursuant to the terms set forth in our partnership agreement, we converted the fifth and final tranche of 2,092,709 of our subordinated units into common units upon satisfaction of the conditions established for conversion. Our partnership agreement provides that, while any subordinated units remained outstanding, holders of our common units had the right to receive distributions of available cash from operating surplus each quarter in an amount equal to our minimum quarterly distribution per unit, plus (with respect to the common units) any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus were made on the subordinated units. Pursuant to the terms of the USD Partners LP Amended and Restated 2014 Long-Term Incentive Plan, which we refer to as the A/R LTIP, our phantom unit awards, or Phantom Units, granted to directors and employees of our general partner and its affiliates, which are classified as equity, are converted into our common units upon vesting. Equity-classified Phantom Units totaling 519,350 vested during the first nine months in 2020, of which 339,736 were converted into our common units after 179,614 Phantom Units were withheld from participants for the payment of applicable employment-related withholding taxes. The conversion of these Phantom Units did not have any economic impact on Partners’ Capital, since the economic impact is recognized over the vesting period. Additional information and discussion regarding our unit based compensation plans is included below in Note 18. Unit Based Compensation . The board of directors of our general partner has adopted a cash distribution policy pursuant to which we intend to distribute at least the minimum quarterly distribution of $0.2875 per unit ($1.15 per unit on an annualized basis) on all of our units to the extent we have sufficient available cash after the establishment of cash reserves and the payment of our expenses, including payments to our general partner and its affiliates. The board of directors of our general partner may change our distribution policy at any time and from time to time. Our partnership agreement does not require us to pay cash distributions on a quarterly or other basis. The amount of distributions we pay under our cash distribution policy and the decision to make any distribution are determined by our general partner. For the quarter ended September 30, 2020, the board of directors of our general partner determined that we had sufficient available cash after the establishment of cash reserves and the payment of our expenses to distribute $0.111 per unit on all of our units.

UNIT BASED COMPENSATION	UNIT BASED COMPENSATION Class A units Our Class A units vested annually over a four year period when established distribution growth target thresholds were met during each year of the four year vesting period. In February 2019, pursuant to the terms set forth in our partnership agreement, the fourth and final vesting tranche of 38,750 Class A units vested based upon our distributions paid for the four preceding quarters and were converted on a basis of one common unit for each Class A unit. As a result, we converted 38,750 Class A units into 38,750 common units in 2019 and no Class A units remain outstanding at September 30, 2020.

We elected to account for actual forfeitures as they occurred rather than applying an estimated forfeiture rate when determining compensation expense. Each holder of a Class A unit was entitled to nonforfeitable cash distributions equal to the product of the number of Class A units outstanding for the participant and the cash distribution per unit paid to our common unitholders. These distributions were included in “Distributions” as presented in our consolidated statements of cash flows and our consolidated statements of partners’ capital. However, any distributions paid on Class A units that were forfeited were reclassified to unit based compensation expense when we determined that the Class A units were not expected to vest. We recognized no compensation expense for the three and nine months ended September 30, 2020 or 2019, for distributions paid on Class A units that were forfeited. Long-term Incentive Plan In 2020 and 2019, the board of directors of our general partner, acting in its capacity as our general partner, approved the grant of 694,140 and 633,637 Phantom Units, respectively, to directors and employees of our general partner and its affiliates under our A/R LTIP. At September 30, 2020, we had 943,489 Phantom Units remaining available for issuance. The Phantom Units are subject to all of the terms and conditions of the A/R LTIP and the Phantom Unit award agreements, which are collectively referred to as the Award Agreements. Award amounts for each of the grants are generally determined by reference to a specified dollar amount based on an allocation formula which included a percentage multiplier of the grantee’s base salary, among other factors, converted to a number of units based on the closing price of one of our common units preceding the grant date, as determined by the board of directors of our general partner and quoted on the NYSE. Phantom Unit awards generally represent rights to receive our common units upon vesting. However, with respect to the awards granted to directors and employees of our general partner and its affiliates domiciled in Canada, for each Phantom Unit that vests, a participant is entitled to receive cash for an amount equivalent to the closing market price of one of our common units on the vesting date. Each Phantom Unit granted under the Award Agreements includes an accompanying distribution equivalent right, or DER, which entitles each participant to receive payments at a per unit rate equal in amount to the per unit rate for any distributions we make with respect to our common units. The Award Agreements granted to employees of our general partner and its affiliates generally contemplate that the individual grants of Phantom Units will vest in four The following tables present the award activity for our Equity-classified Phantom Units: Director and Independent Consultant Phantom Units Employee Phantom Units Weighted-Average Grant Date Fair Value Per Phantom Unit Phantom Unit awards at December 31, 2019 37,139 1,252,544 $ 11.34 Granted 40,065 594,912 $ 10.15 Vested (37,139) (482,211) $ 10.84 Forfeited — (38,955) $ 11.07 Phantom Unit awards at September 30, 2020 40,065 1,326,290 $ 10.98 Director and Independent Consultant Phantom Units Employee Phantom Units Weighted-Average Grant Date Fair Value Per Phantom Unit Phantom Unit awards at December 31, 2018 34,611 1,130,685 $ 11.19 Granted 37,139 544,857 $ 11.37 Vested (34,611) (418,848) $ 11.00 Forfeited — (3,275) $ 10.99 Phantom Unit awards at September 30, 2019 37,139 1,253,419 $ 11.34 The following tables present the award activity for our Liability-classified Phantom Units: Director and Independent Consultant Phantom Units Employee Phantom Units Weighted-Average Grant Date Fair Value Per Phantom Unit Phantom Unit awards at December 31, 2019 12,177 44,620 $ 11.53 Granted 13,136 46,027 $ 10.15 Vested (12,177) — $ 11.37 Phantom Unit awards at September 30, 2020 13,136 90,647 $ 10.76 Director and Independent Consultant Phantom Units Employee Phantom Units Weighted-Average Grant Date Fair Value Per Phantom Unit Phantom Unit awards at December 31, 2018 11,348 29,265 $ 11.31 Granted 12,177 39,464 $ 11.37 Vested (11,348) — $ 11.55 Phantom Unit awards at September 30, 2019 12,177 68,729 $ 11.32 The fair value of each Phantom Unit on the grant date is equal to the closing market price of our common units on the grant date. We account for the Phantom Unit grants to independent directors and employees of our general partner and its affiliates domiciled in Canada that are paid out in cash upon vesting, throughout the requisite vesting period, by revaluing the unvested Phantom Units outstanding at the end of each reporting period and recording a charge to compensation expense in “Selling, general and administrative” in our consolidated statements of operations and recognizing a liability in “Other current liabilities” in our consolidated balance sheets. With respect to the Phantom Units granted to consultants, independent directors and employees of our general partner and its affiliates domiciled in the United States, we amortize the initial grant date fair value over the requisite service period using the straight-line method with a charge to compensation expense in “Selling, general and administrative” in our consolidated statements of operations, with an offset to common units within the Partners’ Capital section of our consolidated balance sheet. For the three months ended September 30, 2020 and 2019, we recognized $1.6 million and $1.5 million, respectively, and for the nine months ended September 30, 2020 and 2019, we recognized $4.9 million and $4.5 million, respectively, of compensation expense associated with outstanding Phantom Units. As of September 30, 2020, we have unrecognized compensation expense associated with our outstanding Phantom Units totaling $11.3 million, which we expect to recognize over a weighted average period of 2.52 years. We have elected to account for actual forfeitures as they occur rather than using an estimated forfeiture rate to determine the number of awards we expect to vest. We made payments to holders of the Phantom Units pursuant to the associated DERs we granted to them under the Award Agreements as follows: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (in thousands) Equity-classified Phantom Units (1) $ 152 $ 471 $ 781 $ 1,358 Liability-classified Phantom Units 12 30 45 74 Total $ 164 $ 501 $ 826 $ 1,432 (1) We had no significant reclassifications to unit based compensation expense for DERs paid in relation to Phantom Units that have been forfeited for the three months ended September 30, 2020 and 2019. We reclassified $57 thousand and $8 thousand for the nine months ended September 30, 2020 and 2019, respectively, for forfeitures.

Consistent with the distribution declared for the first quarter of 2020, the distribution represents a decrease of $0.259 per unit, or 70.0% below the distribution with respect to the fourth quarter of 2019. The distribution will be paid on November 13, 2020, to unitholders of record at the close of business on November 3, 2020. The distribution will include payment of $1.7 million to our public common unitholders, $1.3 million to USDG as a holder of our common units and $51 thousand to USD Partners GP LLC as a holder of the general partner interest. Revolving Credit Facility Activity Subsequent to September 30, 2020, we made additional repayments of $4.0 million under the terms of our existing $385 million Revolving Credit Facility. The Credit Agreement provides for borrowings of up to $385.0 million, expandable to $500.0 million, with lender consent, and expires on November 2, 2022. As of November 2, 2020, we had amounts outstanding of $205.0 million under the Revolving Credit Facility and $180.0 million available for borrowings under the Revolving Credit Facility based on capacity that is subject to certain covenants.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of PresentationOur accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim consolidated financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and disclosures required by GAAP for complete consolidated financial statements. In the opinion of our management, they contain all adjustments, including adjustments made associated with the provisions of the CARES Act discussed above, and consisting only of normal recurring adjustments, which our management considers necessary to present fairly our financial position as of September 30, 2020, our results of operations for the three and nine months ended September 30, 2020 and 2019, and our cash flows for the nine months ended September 30, 2020 and 2019. We derived our consolidated balance sheet as of December 31, 2019 from the audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. Our results of operations for the three and nine months ended September 30, 2020 and 2019 should not be taken as indicative of the results to be expected for the full year due to fluctuations in the supply of and demand for crude oil and biofuels, timing and completion of acquisitions, if any, changes in the fair market value of our derivative instruments and the impact of fluctuations in foreign currency exchange rates. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019.
Foreign Currency Translation	Foreign Currency Translation We conduct a substantial portion of our operations in Canada, which we account for in the local currency, the Canadian dollar. We translate most Canadian dollar denominated balance sheet accounts into our reporting currency, the U.S. dollar, at the end of period exchange rate, while most accounts in our statement of operations are translated into our reporting currency based on the average exchange rate for each monthly period. Fluctuations in the exchange rate between the Canadian dollar and the U.S. dollar can create variability in the amounts we translate and report in U.S. dollars.
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements Intangibles - Goodwill and Other (ASU 2017-04) In January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2017-04, or ASU 2017-04, which amends ASC Topic 350 to modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. Pursuant to the provisions of ASU 2017-04, an entity will no longer determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Rather, an entity will recognize an impairment loss for the amount by which the carrying amount of a reporting unit exceeds the reporting unit’s fair value. However, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit. The pronouncement is effective for fiscal years beginning after December 15, 2019, or for any interim impairment testing within those fiscal years and is required to be applied prospectively, with early adoption permitted. We adopted the provisions of ASU 2017-04 on January 1, 2020. In March 2020, we tested the goodwill associated with our Casper terminal for impairment due to there being circumstances that suggested the fair value of the Casper reporting unit was less than its carrying amount. The circumstances identified related to the overall downturn in the crude market and the decline in the demand for petroleum products, which could lead to delays or reductions of expected throughput levels and changes in expectations for current and future contracts at the Casper terminal. Refer to Note 1. Organization and Basis of Presentation — Recent Events for more information. This standard requires us to recognize an impairment loss for the amount by which the carrying amount of our Casper terminal exceeds the fair value of the terminal. Accordingly, we have recognized an impairment loss in our goodwill asset for the nine months ended September 30, 2020. Refer to Note 8. Goodwill and Intangible assets for more information. Recent Accounting Pronouncements Not Yet Adopted Income Taxes (ASU 2019-12) In December 2019, the FASB issued Accounting Standards Update No. 2019-12, or ASU 2019-12, which amends ASC Topic 740 by removing certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. In addition, under the provisions of ASU 2019-12, single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so.
