Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Consolidation The consolidated financial statements and related notes reflect the accounts of the Company and its wholly-owned subsidiaries. All intercompany profits, transactions and balances have been eliminated. Reclassifications Certain amounts in the prior years’ consolidated financial statements have been reclassified to conform to the current year presentation. Use of Estimates The Company’s consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash, Cash Equivalents and Restricted Cash Cash, cash equivalents and restricted cash include all highly liquid investments with a maturity of three months or less at the time of purchase. Restricted cash represents cash that is legally restricted under the MRL Credit Facility, and it is presented as a non-current asset because it is only available for capital additions related to the renewable diesel project. Accounts Receivable The Company performs periodic credit evaluations of customers’ financial condition and generally does not require collateral. Accounts receivable are carried at their face amounts. The Company maintains an allowance for credit losses for estimated losses in the collection of accounts receivable. The Company makes estimates regarding the future ability of its customers to make required payments based on historical experience, the age of the accounts receivable balances, credit quality of its customers, current economic conditions, expected future trends and other factors that may affect customers’ ability to pay. Individual accounts are written off against the allowance for credit losses after all reasonable collection efforts have been exhausted. The activity in the allowance for credit losses was as follows (in millions): December 31, 2021 2020 Beginning balance $ 0.8 $ 0.9 Provision 1.2 (0.1) Write-offs, net — — Ending balance $ 2.0 $ 0.8 Inventories The cost of inventory is recorded using the last-in, first-out (“LIFO”) method. Costs include crude oil and other feedstocks, labor, processing costs and refining overhead costs. Inventories are valued at the lo wer of cost or market value. The replacement cost of these inventories, based on current market values, would have be en $64.9 million higher than the carrying value of inventory and $6.7 million lower as of December 31, 2021 and 2020, respectively. On March 31, 2017 and June 19, 2017, the Company sold inventory comprised of crude oil and refined products to Macquarie Energy North America Trading Inc. (“Macquarie”) under Supply and Offtake Agreements as described in Note 8 — “Inventory Financing Agreements” related to the Great Falls and Shreveport refineries, respectively. Inventories consist of the following (in millions): December 31, 2021 December 31, 2020 Titled Supply & Offtake Agreements (1) Total Titled Supply & Offtake Agreements (1) Total Raw materials $ 41.0 $ 19.9 $ 60.9 $ 30.8 $ 11.5 $ 42.3 Work in process 52.5 28.5 81.0 31.8 27.4 59.2 Finished goods 121.1 63.6 184.7 114.0 39.4 153.4 $ 214.6 $ 112.0 $ 326.6 $ 176.6 $ 78.3 $ 254.9 (1) Amounts represent LIFO value and do not necessarily represent the value at which the inventory was sold. Please read Note 8 - “Inventory Financing Agreements” for further information. Under the LIFO inventory method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. For the year ended December 31, 2021, the Company re corded a decrease (exclus ive of lower of cost or market (“LCM”) adjustm ents) of $5.6 million in cost of sales in the consolidated statements of operations due to the liquidation of inventory layers. For the year ended December 31, 2020, the Company recorded an increase (exclusive of LCM adjustments) of $4.5 million in cost of sales in the consolidated statements of operations due to the liquidation of inventory layers. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. During the year ended December 31, 2021, the Company record ed a decrease in cost of sales in the consolidated statements of operati ons of $44.7 million due to th e sale of inventory previously adjusted through the LCM valuation. During the year ended December 31, 2020, the Company recorded an increase in cost of sales in the consolidated statements of operations of $24.0 million as a result of declining market prices. Derivatives The Company is exposed to fluctuations in the price of numerous commodities, such as crude oil (its principal raw material), as well as the sales prices of gasoline, diesel, natural gas and jet fuel. Given the historical volatility of commodity prices, these fluctuations can significantly impact sales, gross profit and net income. Therefore, the Company utilizes derivative instruments primarily to minimize its price risk and volatility of cash flows associated with the purchase of crude oil, natural gas, and the sale of fuel products. The Company employs various hedging strategies and does not hold or issue derivative instruments for trading purposes. For further information, please read Note 10 - “Derivatives.” On a regular basis, the Company enters into commodity contracts with counterparties for the purchase or sale of crude oil, blendstocks and various finished products. These contracts usually qualify for the normal purchase / normal sale exemption under ASC 815 and, as such, are not measured at fair value. Property, Plant and Equipment Property, plant and equipment are stated on the basis of cost. Depreciation is calculated using the straight-line method over the estimated useful lives. Assets under finance leases are amortized over the lesser of the useful life of the asset or the term of the lease. Property, plant and equipment, including depreciable lives, consisted of the following (in millions): December 31, 2021 2020 Land $ 8.7 $ 8.7 Buildings and improvements (10 to 40 years) 35.5 35.5 Machinery and equipment (10 to 20 years) 1,649.6 1,625.9 Furniture, fixtures and software (5 to 10 years) 47.9 49.1 Assets under finance leases (1 to 14 years) (1) 8.3 7.4 Construction-in-progress 116.3 28.2 1,866.3 1,754.8 Less accumulated depreciation (916.6) (835.0) $ 949.7 $ 919.8 (1) Assets under finance leases consist of buildings and machinery and equipment. As of December 31, 2021 and 2020, finance lease assets are recorded net of accumulated amortization o f $4.1 million and $3.4 million, respectively. Under the composite depreciation method, the cost of partial retirements of a group is charged to accumulated depreciation. However, when there are dispositions of complete groups or significant portions of groups, the cost and related accumulated depreciation are retired, and any gain or loss is reflected in earnings. During 2021 and 2020, the Company incurred $151.1 million and $126.3 million, respectively, of interest expense of which $1.6 million and $0.4 million, respectively, was capitalized as a component of property, plant and equipment. The Company periodically assesses its operations and legal requirements to determine if recognition of an asset retirement obligation is necessary. The Company has not recorded an asset retirement obligation as of December 31, 2021 or 2020 given the timing of any retirement and related costs are currently indeterminable. During the years ended December 31, 2021 and 2020, the Company recorded $95.9 million and $91.1 million, respectively, of depreciation expense on its property, plant and equipment. Depreciation expense included $0.7 million and $0.6 million for the years ended 2021 and 2020, respectively, related to the Company’s finance lease assets. The Company capitalizes the cost of computer software developed or obtained for internal use. Capitalized software is amortized using the straight-line method over five Goodwill Goodwill represents the excess of purchase price over fair value of the net assets acquired in various acquisitions. Please read Note 6 - “Goodwill and Other Intangible Assets” for more information. The Company assesses goodwill for impairment annually and whenever events or changes in circumstances indicate its carrying value may not be recoverable in accordance with ASC 350, Intangibles — Goodwill and Other (Topic 350) and ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . Under ASC 350, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the impairment test is unnecessary. The Company tests goodwill either quantitatively or qualitatively for impairment. The Company assessed goodwill for impairment qualitatively and quantitatively during the years ended December 31, 2021 and 2020, respectively. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company assesses relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgment and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and Company specific events and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. In the first step of the quantitative assessment, the Company’s assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. Under ASU 2017-04, goodwill impairment testing is done by comparing the fair value of the reporting unit to its carrying value. If the carrying amount exceeds the fair value, the Company would recognize an impairment charge for the amount that the reporting unit's carrying value exceeds the fair value, not to exceed the total amount of goodwill allocated to that reporting unit. When performing the quantitative assessment, the fair value of the reporting units is determined using the income approach. The income approach focuses on the income-producing capability of the reporting unit, measuring the current value of the reporting unit by calculating the present value of its future economic benefits such as cash earnings, cost savings, corporate tax structure and product offerings. Value indications are developed by discounting expected cash flows to their present value at a rate of return that incorporates the risk-free rate for the use of funds, the expected rate of inflation, and risks associated with the reporting unit. For more information, please read Note 6 - “Goodwill and Other Intangible Assets.” Finite-Lived Intangible Assets Finite-lived intangible assets consist of intangible assets associated with customer relationships, tradenames, trade secrets, patents and royalty agreements that were acquired in various acquisitions. The majority of these assets are being amortized using undiscounted estimated future cash flows over the term of the related agreements. Intangible assets associated with customer relationships are being amortized using the undiscounted estimated future cash flows method based upon assumed rates of annual customer attrition. For more information, please read Note 6 - “Goodwill and Other Intangible Assets.” Other Noncurrent Assets Other noncurrent assets include turnaround costs. Turnaround costs represent capitalized costs associated with the Company’s periodic major maintenance and repairs and the net carrying value of turnaround costs included in other noncurrent assets in the consolidated balance sheets w ere $82.3 million and $34.2 million as of December 31, 2021 and 2020, respectively. The Company capitalizes these costs and amortizes the costs on a straight-line basis over the lives of the turnaround assets which is generally two five of $41.5 million and $60.5 million at December 31, 2021 and 2020, respectively. Renewable Identification Numbers (“RINs”) Obligation The Company’s RINs obligation (“RINs Obligation”) is an estimated provision for the future purchase of RINs in order to satisfy the U.S. Environmental Protection Agency’s (“EPA”) requirement to blend renewable fuels into certain transportation fuel products pursuant to the Renewable Fuel Standard (“RFS”). A RIN is a 38-character number assigned to each physical gallon of renewable fuel produced in or imported into the United States. The EPA sets annual volume obligations for the percentage of renewable fuels that must be blended into transportation fuels consumed in the U.S. and, as a producer of transportation fuels from petroleum, the Company is subject to those obligations. Compliance is demonstrated by tendering RINs to the EPA documenting that blending has been accomplished. To the extent the Company is unable to physically blend renewable fuels to satisfy the EPA requirement, it may purchase RINs in the open market to satisfy the annual obligations. The Company accounts for its current period RINs obligation by multiplying the quantity of RINs shortage (based on actual results) by the period end RINs spot price, which is recorded as a RINs obligation in the consolidated balance sheets. The Company’s RINs obligations for compliance years 2019 and 2020 are presented as a current liability in the consolidated balance sheets and the Company’s RINs obligation for compliance year 2021 is presented as a long-term liability in the consolidated balance sheets. This liability is revalued at the end of each subsequent accounting period, which produces non-cash mark-to-market adjustments that are reflected in cost of sales in the consolidated statements of operations (with the exception of RINs for compliance year 2019 related to the San Antonio refinery, which amount is reflected in other operating expense in the consolidated statements of operations). RINs generated by blending may be sold or held to offset future RINs Obligations. Any gains or losses from RINs sales are recorded in cost of sales in the consolidated statements of operations. The liabilities associated with the Company’s RINs obligation are considered recurring fair value measurements. Please read Note 7 - “Commitments and Contingencies” for further information on the Company’s RINs Obligation. Impairment of Long-Lived Assets The Company periodically evaluates the carrying value of long-lived assets to be held and used, including finite-lived intangible assets, when events or circumstances warrant such a review. The carrying value of a long-lived asset to be held and used is considered impaired when the anticipated separately identifiable undiscounted cash flows from such an asset are less than the carrying value of the asset. In such an event, a write-down of the asset would be recorded through a charge to operations, based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using anticipated cash flows assumed by a market participant discounted at a rate commensurate with the risk involved. Long-lived assets to be disposed of other than by sale are considered held and used until disposal. During the years ended December 31, 2021 and 2020, the Company did not identify any impairment indicators that suggested the carrying values of its long-lived assets are not recoverable at the asset groups within the Specialty Products and Solutions, Montana/Renewables, Performance Brands and Corporate segments. As a result of the long-lived asset impairment assessment performed, no im pairment charges were recorded for the years ended December 31, 2021 and 2020. For the year ended December 31, 2020, the Company recorded a loss of $5.1 million for the write-off of an other receivable for payments due from an unconsolidated affiliate, which is included in loss on impairment and disposal of assets in the consolidated statements of operations. Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue Recognition, which states that revenue is recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods. Please read Note 4 - “Revenue Recognition” for additional information on our revenue recognition accounting policies and elections. Revenues associated with transactions commonly called buy/sell contracts, in which the purchase and sale of inventory with the same counterparty are entered into “in contemplation” of one another, are combined and reported as a net purchase in cost of sales in the consolidated statements of operations. Concentrations of Credit Risk The Company performs periodic credit evaluations of its customers’ financial condition and in some instances requires cash in advance or letters of credit prior to shipment for domestic orders. For international orders, letters of credit are generally required, and the Company maintains insurance policies which cover certain export orders. The Company maintains an allowance for credit losses account for estimated losses resulting from the inability of its customers to make required payments. The allowance for credit losses is developed based on several factors including historical experience, the age of the accounts receivable balances, credit quality of the Company’s customers, current economic conditions, expected future trends and other factors that may affect customers’ ability to pay, which exist as of the balance sheet dates. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has derivative positions with a limited number of counterparties. The evaluation of these counterparties is performed quarterly in connection with the Company’s ASC 820-10, Fair Value Measurements and Disclosures, valuations to determine the impact of the counterparty credit risk on the valuation of its derivative instruments. Earnings per Unit The Company calculates earnings per unit under ASC 260-10, Earnings per Share . The Company treats incentive distribution rights (“IDRs”) as participating securities for the purposes of computing earnings per unit in the period that the general partner becomes contractually obligated to receive IDRs. Also, the undistributed earnings are allocated to the partnership interests based on the allocation of earnings to the Company’s partners’ capital accounts as specified in the Company’s partnership agreement. When distributions exceed earnings, net income is reduced by the actual distributions with the resulting net loss being allocated to capital accounts as specified in the Company’s partnership agreement. Unit-Based Compensation For unit-based compensation equity awards granted, compensation expense is recognized in the Company’s consolidated financial statements on a straight-line basis over the awards’ vesting periods based on their fair values on the dates of grant. The unit-based compensation awards vest over a period not exceeding four years. The amount of compensation expense recognized at any date is at least equal to the portion of the grant date value of the award that is vested at that date. For more information, please re ad Note 13 - “Unit-Based Compensation.” Unit-based compensation liability awards are awards that are currently expected to be settled in cash on their vesting dates, rather than in equity units (“Liability Awards”). Liability Awards are recorded in accrued salaries, wages and benefits based on the vested portion of the fair value of the awards on the balance sheet date. The fair value of Liability Awards is updated at each balance sheet date and changes in the fair value of the vested portions of the Liability Awards are recorded as increases or decreases to compensation expense. The Company recognizes forfeitures as they occur. Please read Note 13 - “Unit-Based Compensation” for more information on Liability Awards. Advertising Expenses The Company expenses advertising costs as incurred which tot aled $7.4 million and $4.3 million for the years ended December 31, 2021 and 2020, respectively. Advertising expenses are reported as selling expenses in the consolidated statements of operations. Recently Adopted Accounting Pronouncements On January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which changed the impairment model for most financial instruments. Previous guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflects losses once the losses are probable. Under ASU 2016-13, the Company is required to use a current expected credit loss (“CECL”) model that immediately recognizes an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of the update, including trade receivables. The CECL model uses a broader range of reasonable and supportable information in the development of credit loss estimates. The result of the adoption of ASU 2016-13 was de-minimis and did not result in an adjustment to beginning partners’ capital (deficit). The allowance for credit losses for accounts receivable was $2.0 million and $0.8 million at December 31, 2021 and 2020, respectively.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Recognition The following is a description of principal activities from which the Company generates revenue. Revenues are recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines the performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Products The Company manufactures, formulates, and markets a diversified slate of specialty branded products to customers in various consumer-facing and industrial markets. The Company also produces fuel and fuel related products, including gasoline, diesel, jet fuel, asphalt, and other fuels products. The Company also blends, packages and markets high-performance branded specialty products through its Royal Purple, Bel-Ray, and TruFuel brands. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to variable consideration such as product returns, rebates or other discounts to determine the net consideration to which the Company expects to be entitled. The Company transfers control and recognizes revenue upon shipment to the customer or, in certain cases, upon receipt by the customer in accordance with contractual terms. Revenue is recognized when obligations under the terms of a contract with a customer are satisfied and control of the promised goods are transferred to the customer. The contract with the customer states the final terms of the sale, including the description, quantity and price of each product or service purchased. For fuel products, payment is typically due in full between 2 to 30 days of delivery or the start of the contract term, such that payment is typically collected 2 to 30 days subsequent to the satisfaction of performance obligations. For specialty products, payment is typically due in full between 30 to 90 days of delivery or the start of the contract term, such that payment is typically collected 30 to 90 days subsequent to the satisfaction of performance obligations. In the normal course of business, the Company does not accept product returns unless the item is defective as manufactured. The expected costs associated with a product assurance warranty continues to be recognized as expense when products are sold. The Company does not offer promised services that could be considered warranties that are sold separately or provide a service in addition to assurance that the related product complies with agreed upon specifications. The Company establishes provisions based on the methods described in ASC 606 for estimated returns and warranties as variable consideration when determining the transaction price. Excise and Sales Taxes The Company assesses, collects and remits excise taxes associated with the sale of certain of its fuel products. Furthermore, the Company collects and remits sales taxes associated with certain sales of its products to non-exempt customers. The Company excludes excise taxes and sales taxes that are collected from customers from the transaction price in its contracts with customers. Accordingly, revenue from contracts with customers is net of sales-based taxes that are collected from customers and remitted to taxing authorities. Shipping and Handling Costs Shipping and handling costs are deemed to be fulfillment activities rather than a separate distinct performance obligation. Cost of Obtaining Contracts The Company may incur incremental costs to obtain a sales contract, which under ASC 606 should be capitalized and amortized over the life of the contract. The Company has elected to apply the practical expedient in ASC 340-40-50-5 allowing the Company to expense these costs since the contracts are short-term in nature with a contract term of one year or less. Contract Balances Under product sales contracts, the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional. Accordingly, a product sales contract does not give rise to contract assets or liabilities under ASC 606. The Company’s receivables, net of allowance for expected credit losses from contracts with customers as of December 31, 2021 and 2020 wa s $216.8 million a nd $152.4 million, respectively. Transaction Price Allocated to Remaining Performance Obligations The Company’s product sales are short-term in nature with a contract term of one year or less. The Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. Additionally, each unit of product generally represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets For the years ended December 31, 2021 and 2020, the Company performed its annual goodwill assessment for each of the years then ended, respectively, and determined that the fair value of each of its reporting units with goodwill exceeded its carrying value. Thus, no impairment charge for goodwill related to the Specialty Products and Solutions segment or Performance Brands segment was recorded in the consolidated statements of operations within asset impairment for the years ended December 31, 2021 and 2020, respectively. There is no goodwill within the reporting units for the Montana/Renewables segment or the Corporate segment. Inputs used to estimate the fair value of the Company’s reporting units are considered Level 3 inputs of the fair value hierarchy and include the following: • The Company’s financial projections for its reporting units are based on its analysis of various supply and demand factors which include, among other things, industry-wide capacity, its planned utilization rate, end-user demand, crack spreads, capital expenditures and economic conditions. Such estimates are consistent with those used in the Company’s planning and capital investment reviews and include recent historical prices and published forward prices. • The discount rate used to measure the present value of the projected future cash flows is based on a variety of factors, including market and economic conditions, operational risk, regulatory risk and political risk. This discount rate is also compared to recent observable market transactions, if possible. For Level 3 measurements, significant increases or decreases in long-term growth rates or discount rates in isolation or in combination could result in a significantly lower or higher fair value measurement. Changes in goodwill balances for the periods indicated below are as follows (in millions): Specialty Performance Brands Consolidated Total Net balance as of December 31, 2019 $ 47.7 $ 123.7 $ 171.4 Additions 1.6 — 1.6 Impairment (1) — — — Net balance as of December 31, 2020 $ 49.3 $ 123.7 $ 173.0 Additions — — — Impairment (1) — — — Net balance as of December 31, 2021 $ 49.3 $ 123.7 $ 173.0 (1) Total accumulated goodwill impairment as of December 31, 2021 and 2020, is $35.5 million.

The costs of agreements with terms allowing for the potential extension of such agreements are being amortized based on the initial term only. Customer relationships are being amortized to properly match expenses with the undiscounted estimated future cash flows based upon assumed rates of annual customer attrition. For the years ended December 31, 2021 and 2020, the Company recorded amortization expense of intangible ass ets of $11.8 million and $14.3 million , respectively. As of December 31, 2021, the Company estimates that amortization of intangible assets for the next five years will be as follows (in millions): Year Amortization Amount 2022 $ 9.5 2023 $ 7.8 2024 $ 6.5 2025 $ 4.9 2026 $ 3.8

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies From time to time, the Company is a party to certain claims and litigation incidental to its business, including claims made by various taxation and regulatory authorities, such as the Internal Revenue Service, the EPA and the U.S. Occupational Safety and Health Administration (“OSHA”), as well as various state environmental regulatory bodies and state and local departments of revenue, as the result of audits or reviews of the Company’s business. In addition, the Company has property, business interruption, general liability and various other insurance policies that may result in certain losses or expenditures being reimbursed to the Company. Environmental The Company conducts crude oil and specialty refining, blending and terminal operations and such activities are subject to stringent federal, regional, state and local laws and regulations governing worker health and safety, the discharge of materials into the environment and environmental protection. These laws and regulations impose obligations that are applicable to the Company’s operations, such as requiring the acquisition of permits to conduct regulated activities, restricting the manner in which the Company may release materials into the environment, requiring remedial activities or capital expenditures to mitigate pollution from former or current operations, requiring the application of specific health and safety criteria addressing worker protection and imposing substantial liabilities for pollution resulting from its operations. Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil and criminal penalties; the imposition of investigatory, remedial or corrective action obligations or the incurrence of capital expenditures; the occurrence of delays in the permitting, development or expansion of projects and the issuance of injunctive relief limiting or prohibiting Company activities. Moreover, certain of these laws impose joint and several, strict liability for costs required to remediate and restore sites where petroleum hydrocarbons, wastes or other materials have been released or disposed. In addition, new laws and regulations, new interpretations of existing laws and regulations, increased governmental enforcement or other developments, some of which legal requirements are discussed below, could significantly increase the Company’s operational or compliance expenditures. Remediation of subsurface contamination is in process at certain of the Company’s refinery sites and is being overseen by the appropriate state agencies. Based on current investigative and remedial activities, the Company believes that the soil and groundwater contamination at these refineries can be controlled or remediated without having a material adverse effect on the Company’s financial condition. However, such costs are often unpredictable and, therefore, there can be no assurance that the future costs will not become material. Renewable Identification Numbers Obligation The RFS allows small refineries to apply at any time for a Small Refinery Exemption (“SRE”) from the renewable blending requirements, and Calumet had applied in respect of calendar 2019 and 2020 compliance years. The EPA has not taken a final action on 2019 and 2020 SRE applications. On January 19, 2021, the Company filed a lawsuit against Mr. Andrew Wheeler, who was then Administrator of the EPA, in federal court in the Western District of Louisiana and in the District of Montana seeking an order that the EPA cannot enforce the RINs compliance deadline until the EPA has taken action on the Company’s hardship exemption applications. Both cases currently are stayed through June 30, 2022. Subsequent to the Company filing those lawsuits, EPA extended the deadlines for 2019 RFS compliance to November 30, 2021 and for 2020 RFS compliance to January 31, 2022. On January 27, 2022, EPA further extended the compliance reporting deadlines and attestation engagement reporting deadlines for program years 2019, 2020 and 2021, calculated based on the future effective dates of other EPA RFS rulemakings. In December 2021, EPA issued a proposal to deny all currently pending petitions from small refineries seeking SREs, including for program years 2019 and 2020, based on an across the board determination that no refinery suffers disproportionate economic hardship from the RFS program. EPA has not yet taken final action on this proposal. The Company continues to anticipate that RFS compliance may continue to result in a significant expense for the Specialty Products and Solutions and Montana/Renewables segments. If legal or regulatory changes occur that have the effect of increasing the RINs Obligation, increasing the market price of RINs, or eliminating or narrowing the availability of SRE, the Company could be required to purchase additional RINs in the open market, which may materially increase the costs related to RFS compliance and could have a material adverse effect on the results of operations and liquidity. As of December 31, 2021 and 2020, the Company had a RINs Obligation recorded on the consolidated balance sheets of $278.9 million and $129.4 million, respectively. Please read Note 3 - “Summary of Significant Accounting Policies” for additional information. Occupational Health and Safety The Company is subject to various laws and regulations relating to occupational health and safety, including the federal Occupational Safety and Health Act, as amended, and comparable state laws. These laws and regulations strictly govern the protection of the health and safety of employees. In addition, OSHA’s hazard communication standard, the EPA’s community right-to-know regulations under Title III of the federal Comprehensive Environmental Response, Compensation and Liability Act, as amended, and similar state statutes require the Company to maintain information about hazardous materials used or produced in the Company’s operations and provide this information to employees, contractors, state and local government authorities and customers. The Company maintains safety and training programs as part of its ongoing efforts to promote compliance with applicable laws and regulations. The Company conducts periodic audits of process safety management systems at each of its locations subject to this standard. The Company’s compliance with applicable health and safety laws and regulations has required, and continues to require, substantial expenditures. Changes in occupational safety and health laws and regulations or a finding of non-compliance with current laws and regulations could result in additional capital expenditures or operating expenses, as well as civil penalties and, in the event of a serious injury or fatality, criminal charges. Labor Matters The Company has approximately 550 employees covered by various collective bargaining agreements, or approximately 38% of its total workforce of approximately 1,450 employees. These agreements have expiration dates of April 30, 2022, July 31, 2022, January 15, 2023, January 31, 2023, August 20, 2024 and December 12, 2024 . The Company has approximately 335 employees, or 23% of its total workforce, who are covered by a collective bargaining agreement which will expire in less than one year and does not expect any work stoppages. Other Matters, Claims and Legal Proceedings Beginning in 2017, the Company initiated the first of several claims in Cascade County Circuit Court against the Montana Department of Revenue to recover overpaid taxes resulting from the county’s excessive property tax assessment of the Company’s Great Falls refinery for the 2017, 2018, and 2019 tax years. For the year ended December 31, 2020, the county had refunded, as the result of various court decisions, $6.0 million in excessive taxes and interest to the Company. The claims arising from the 2017, 2018, and 2019 tax years are closed. The $6.0 million was recorded as a reduction of taxes other than income taxes in the consolidated statements of operations for the year ended December 31, 2020. The Company is subject to other matters, claims and litigation incidental to its business. The Company has recorded accruals with respect to certain of its matters, claims and litigation where appropriate, that are reflected in the audited consolidated financial statements but are not individually considered material. For other matters, claims and litigation, the Company has not recorded accruals because it has not yet determined that a loss is probable or because the amount of loss cannot be reasonably estimated. While the ultimate outcome of matters, claims and litigation currently pending cannot be determined, the Company currently does not expect these outcomes, individually or in the aggregate (including matters for which the Company has recorded accruals), to have a material adverse effect on its financial position, results of operations or cash flows. The outcome of any matter, claim or litigation is inherently uncertain, however, and if decided adversely to the Company, or if the Company determines that settlement of particular litigation is appropriate, the Company may be subject to liability that could have a material adverse effect on its financial position, results of operations or cash flows. Standby Letters of Credit The Company has agreements with various financial institutions for standby letters of credit which have been issued primarily to vendors. As of December 31, 2021 and 2020, the Company had outstanding standby letters of credit of $32.7 million and $23.7 million, respectively, under its senior secured revolving credit facility (the “revolving credit facility”). Please read Note 9 - “Long-Term Debt” for additional information regarding the Company’s revolving credit facility. At December 31, 2021 and 2020, the maximum amount of letters of credit the Company could issue under its revolving credit facility was subject to borrowing base limitations, with a maximum letter of credit sublimit equal to $300.0 million, which may be increased with consent of the Agent (as defined in the Credit Agreement) to 90% of revolver commitments then in effect ($600.0 million at December 31, 2021 and 2020). As of December 31, 2021 and 2020, the Company had availability to issue letters of credit of approximatel y $296.0 million and approximately $154.4 million, respectively, under its revolving credit facility. Crude Oil Supply, Other Feedstocks and Finished Products Purchase commitments consist primarily of obligations to purchase fixed volumes of crude oil, other feedstocks and finished products for resale from various suppliers based on current market prices at the time of delivery. The Company is currently purchasing a majority of its crude oil under month-to-month evergreen contracts or on a spot basis. Certain other feedstocks are purchased under long-term supply contracts. As of December 31, 2021, the estimated minimum purchase commitments under the Company’s crude oil, other feedstock supply and finished product agreements were as follows (in millions): Year Commitment 2022 $ 22.8 2023 22.8 2024 22.9 2025 22.8 2026 22.8 Thereafter 9.8 Total $ 123.9 Throughput Contract Prior to 2020, the Company entered into a long-term agreement to transport crude oil at a minimum of 5,000 bpd through a pipeline, which commenced service in the second quarter of 2020. The agreement also contains a capital recovery charge that increases 2% per annum. The agreement is for seven years. As of December 31, 2021, the estimated minimum unconditional purchase commitments, including the capital recovery charge, under the agreement were as follows (in millions): Year Commitment (1) 2022 $ 3.9 2023 3.9 2024 4.0 2025 4.0 2026 4.0 Thereafter 2.0 Total (1) $ 21.8

Inventory Financing Agreement I

Inventory Financing Agreement Inventory Financing Agreement (Notes)	12 Months Ended

Inventory Financing Agreement [Abstract]
Supply And Exchange Agreements [Text Block]	Inventory Financing Agreements The Company is party to several agreements with Macquarie to support the operations of the Great Falls refinery and the Shreveport refinery (as amended, the “Supply and Offtake Agreements”). Both agreements have an expiration date of June 30, 2023. The Supply and Offtake Agreements allow the Company to purchase crude oil from Macquarie or one of its affiliates. Per the Supply and Offtake Agreements, Macquarie will provide up to 30,000 barrels per day of crude oil to the Great Falls refinery and 60,000 barrels per day of crude oil to the Shreveport refinery. While title to certain inventories will reside with Macquarie, the Supply and Offtake Agreements are accounted for by the Company similar to a product financing arrangement; therefore, the inventories sold to Macquarie will continue to be included in the Company’s consolidated balance sheets until processed and sold to a third party. For the years ended December 31, 2021 and 2020, the Company incurred an expense of $15.4 million and received a $1.1 million benefit, respectively, for financing costs related to the Supply and Offtake Agreements, which are included in interest expense in the Company’s consolidated statements of operations. The Company has provided cash collateral of $13.1 million relate d to the initial purchase of the Great Falls and Shreveport inventory to cover credit risk for future crude oil deliveries and potential liquidation risk if Macquarie exercises its rights and sells the inventory to third parties. The collateral was recorded as a reduction to the obligations. The Supply and Offtake Agreements also include a deferred payment arrangement (“Deferred Payment Arrangement”) whereby the Company can defer payments on just-in-time crude oil purchases from Macquarie owed under the agreements up to the value of the collateral provided (90% of the collateral is inventory). The deferred amounts under the Deferred Payment Arrangement will bear interest at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 3.25% per annum for both Shreveport and Great Falls. Amounts outstanding under the Deferred Payment Arrangement are included in obligations under inventory financing agreements in the Company’s consolidated balance sheets. Changes in the amount outstanding under the Deferred Payment Arrangement are included within cash flows from financing activities in the consolidated statements of cash flows. As of December 31, 2021 and December 31, 2020, the Company had $17.0 million

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company is exposed to price risks due to fluctuations in the price of crude oil, refined products, natural gas and precious metals. The Company uses various strategies to reduce its exposure to commodity price risk. The strategies to reduce the Company’s risk utilize both physical forward contracts and financially settled derivative instruments, such as swaps, collars, options and futures, to attempt to reduce the Company’s exposure with respect to: • crude oil purchases and sales; • fuel product sales and purchases; • natural gas purchases; • precious metals purchases; and • fluctuations in the value of crude oil between geographic regions and between the different types of crude oil such as New York Mercantile Exchange West Texas Intermediate (“NYMEX WTI”), Light Louisiana Sweet, Western Canadian Select (“WCS”), WTI Midland, Mixed Sweet Blend, Magellan East Houston and ICE Brent. The Company manages its exposure to commodity markets, credit, volumetric and liquidity risks to manage its costs and volatility of cash flows as conditions warrant or opportunities become available. These risks may be managed in a variety of ways that may include the use of derivative instruments. Derivative instruments may be used for the purpose of mitigating risks associated with an asset, liability and anticipated future transactions and the changes in fair value of the Company’s derivative instruments will affect its earnings and cash flows; however, such changes should be offset by price or rate changes related to the underlying commodity or financial transaction that is part of the risk management strategy. The Company does not speculate with derivative instruments or other contractual arrangements that are not associated with its business objectives. Speculation is defined as increasing the Company’s natural position above the maximum position of its physical assets or trading in commodities, currencies or other risk bearing assets that are not associated with the Company’s business activities and objectives. The Company’s positions are monitored routinely by a risk management committee to ensure compliance with its stated risk management policy and documented risk management strategies. All strategies are reviewed on an ongoing basis by the Company’s risk management committee, which will add, remove or revise strategies in anticipation of changes in market conditions and/or its risk profiles. Such changes in strategies are to position the Company in relation to its risk exposures in an attempt to capture market opportunities as they arise. The Company is obligated to repurchase crude oil and refined products from Macquarie at the termination of the Supply and Offtake Agreements in certain scenarios. The Company has determined that the redemption feature on the initially recognized liability related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for this embedded derivative at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s consolidated statements of operations please read Note 8 - “Inventory Financing Agreements" for additional information. The Company recognizes all derivative instruments at their fair values as either current assets or current liabilities in the consolidated balance sheets (please read Note 11 - “Fair Value Measurements”). Fair value includes any premiums paid or received and unrealized gains and losses. Fair value does not include any amounts receivable from or payable to counterparties, or collateral provided to counterparties. Derivative asset and liability amounts with the same counterparty are netted against each other for financial reporting purposes in accordance with the provisions of our master netting arrangements.

The majority of the credit support agreements covering the Company’s outstanding derivative instruments also contain a general provision stating that if the Company experiences a material adverse change in its business, in the reasonable discretion of the counterparty, the Company’s credit threshold could be lowered by such counterparty. The Company does not expect that it will experience a material adverse change in its business. The cash flow impact of the Company’s derivative activities are included within cash flows from operating activities in the consolidated statements of cash flows. Derivative Instruments Not Designated as Hedges For derivative instruments not designated as hedges, the change in fair value of the asset or liability for the period is recorded to unrealized gain (loss) on derivative instruments in the consolidated statements of operations. Upon the settlement of a derivative not designated as a hedge, the gain or loss at settlement is recorded to realized gain (loss) on derivative instruments in the consolidated statements of operations. The Company has entered into natural gas swaps, crack spread swaps and crude oil basis swaps that are not designated as cash flow hedges for accounting purposes. However, these instruments provide economic hedges of the purchases and sales of the Company’s natural gas, crude oil, gasoline and refined products. The Company recorded the following gains (losses) in its consolidated statements of operations related to its derivative instruments not designated as hedges (in millions): Amount of Gain (Loss) Amount of Gain (Loss) Year Ended December 31, Year Ended December 31, Type of Derivative 2021 2020 2021 2020 Specialty Products and Solutions segment: Inventory financing obligation $ — $ — $ (16.3) $ 4.0 Natural gas swaps — 0.2 — — Crack spread swaps — 29.9 — (2.2) Montana/Renewables segment: Inventory financing obligation — — (9.4) 1.1 WCS crude oil basis swaps 1.1 19.5 1.3 (0.1) Total $ 1.1 $ 49.6 $ (24.4) $ 2.8 Derivative Positions As of December 31, 2021, the Company had no outstanding derivative contracts.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. These tiers include the following: • Level 1 — inputs include observable unadjusted quoted prices in active markets for identical assets or liabilities • Level 2 — inputs include other than quoted prices in active markets that are either directly or indirectly observable • Level 3 — inputs include unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions In determining fair value, the Company uses various valuation techniques and prioritizes the use of observable inputs. The availability of observable inputs varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded and other characteristics particular to the instrument. For many financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants and the valuation does not require significant management judgment. For other financial instruments, pricing inputs are less observable in the marketplace and may require management judgment. Recurring Fair Value Measurements Derivative Assets and Liabilities Derivative instruments are reported in the accompanying consolidated financial statements at fair value. The Company’s derivative instruments consist of over-the-counter (“OTC”) contracts, which are not traded on a public exchange. Substantially all of the Company’s derivative instruments are with counterparties that have long-term credit ratings of at least A3 and BBB+ by Moody’s and S&P, respectively. To estimate the fair values of the Company’s commodity derivative instruments, the Company uses the forward rate, the strike price, contractual notional amounts, the risk free rate of return and contract maturity. Various analytical tests are performed to validate the counterparty data. The fair values of the Company’s derivative instruments are adjusted for nonperformance risk and creditworthiness of the hedging entities through the Company’s credit valuation adjustment (“CVA”). The CVA is calculated at the counterparty level utilizing the fair value exposure at each payment date and applying a weighted probability of the appropriate survival and marginal default percentages. The Company uses the counterparty’s marginal default rate and the Company’s survival rate when the Company is in a net asset position at the payment date and uses the Company’s marginal default rate and the counterparty’s survival rate when the Company is in a net liability position at the payment date. Observable inputs utilized to estimate the fair values of the Company’s derivative instruments were based primarily on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Based on the use of various unobservable inputs, principally non-performance risk, creditworthiness of the hedging entities and unobservable inputs in the forward rate, the Company has categorized these derivative instruments as Level 3. Significant increases (decreases) in any of those unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement. The Company believes it has obtained the most accurate information available for the types of derivative instruments it holds. Please read Note 10 - “Derivatives” for further information on derivative instruments. Pension Assets Pension assets are reported at fair value in the accompanying consolidated financial statements. At December 31, 2021 and 2020, the Company’s investments associated with its Pension Plan (as such term is hereinafter defined) consisted of (i) cash and cash equivalents, (ii) fixed income bond funds, (iii) mutual equity funds, and (iv) mutual balanced funds. The fixed income bond funds, mutual equity funds, and mutual balanced funds are measured at fair value using a market approach based on quoted prices from national securities exchanges and are categorized in Level 1 of the fair value hierarchy. Liability Awards Unit-based compensation Liability Awards are awards that are currently expected to be settled in cash on their vesting dates, rather than in equity units. The Liability Awards are categorized as Level 1 because the fair value of the Liability Awards is based on the Company’s quoted closing unit price as of each balance sheet date. Renewable Identification Numbers Obligation The Company’s RINs Obligation is categorized as Level 2 and is measured at fair value using the market approach based on prices obtained from an independent pricing serv ice. Please read Note 3 - “Summary of Significant Accounting Policies” f or further information on the Company’s RINs Obligation. Precious Metals Obligations The fair value of precious metals obligations is based upon unadjusted exchange-quoted prices and is, therefore, classified within Level 1 of the fair value hierarchy. Hierarchy of Recurring Fair Value Measurements The Company’s recurring assets and liabilities measured at fair value were as follows (in millions): December 31, 2021 December 31, 2020 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Pension Plan investments $ 34.5 $ — $ — $ 34.5 $ 34.4 $ — $ — $ 34.4 Total recurring assets at fair value $ 34.5 $ — $ — $ 34.5 $ 34.4 $ — $ — $ 34.4 Liabilities: Derivative liabilities: Inventory financing obligation $ — $ — $ (27.9) $ (27.9) $ — $ — $ (2.2) $ (2.2) WCS crude oil basis swaps — — — — — — (1.3) (1.3) Total derivative liabilities $ — $ — $ (27.9) $ (27.9) $ — $ — $ (3.5) $ (3.5) RINs obligation — (278.9) — (278.9) — (129.4) — (129.4) Precious metals obligations (6.8) — — (6.8) (7.9) — — (7.9) Liability Awards (63.1) — — (63.1) (14.2) — — (14.2) Total recurring liabilities at fair value $ (69.9) $ (278.9) $ (27.9) $ (376.7) $ (22.1) $ (129.4) $ (3.5) $ (155.0) The table below sets forth a summary of net changes in fair value of the Company’s Level 3 financial assets and liabilities (in millions): For the Year Ended December 31, 2021 2020 Fair value at January 1, $ (3.5) $ (6.3) Realized gain on derivative instruments 1.1 49.6 Unrealized gain (loss) on derivative instruments (24.4) 2.8 Settlements (1.1) (49.6) Fair value at December 31, $ (27.9) $ (3.5) Total gain (loss) included in net loss attributable to changes in unrealized gain (loss) relating to financial assets and liabilities held as of December 31, $ (24.4) $ 2.8 Nonrecurring Fair Value Measurements Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. The Company assesses goodwill for impairment annually and whenever events or changes in circumstances indicate its carrying value may not be recoverable. The fair value of the reporting units is determined using the income approach. The income approach focuses on the income-producing capability of an asset, measuring the current value of the asset by calculating the present value of its future economic benefits such as cash earnings, cost savings, corporate tax structure and product offerings. Value indications are developed by discounting expected cash flows to their present value at a rate of return that incorporates the risk-free rate for the use of funds, the expected rate of inflation and risks associated with the reporting unit. These assets would generally be classified within Level 3, in the event that the Company were required to measure and record such assets at fair value within its consolidated financial statements. Please read Note 6 - “Goodwill and Other Intangible Assets” for further information on goodwill impairment. The Company periodically evaluates the carrying value of long-lived assets to be held and used, including finite-lived intangible assets and property plant and equipment, when events or circumstances warrant such a review. Fair value is determined primarily using anticipated cash flows assumed by a market participant discounted at a rate commensurate with the risk involved and these assets would generally be classified within Level 3, in the event that the Company was required to measure and record such assets at fair value within its consolidated financial statements. Please read Note 3 - “Summary of Significant Accounting Policies” for further information on long-lived asset impairment. Estimated Fair Value of Financial Instruments Cash, cash equivalents and restricted cash The carrying value of cash, cash equivalents and restricted cash are each considered to be representative of their fair value. Debt The estimated fair value of long-term debt at December 31, 2021 and 2020, consists primarily of senior notes. The estimated aggregate fair value of the Company’s 2022 Notes and 2023 Notes defined as Level 1 was based upon quoted market prices in an active market. The estimated fair value of the Company’s 2024 Secured Notes and 2025 Senior Notes defined as Level 2 was based upon quoted prices for identical or similar liabilities in markets that are not active. The carrying value of borrowings, if any, under the Company’s revolving credit facility, MRL Credit Facility, finance lease obligations and other obligations are classified as Level 3. Please read Note 9 - “Long-Term Debt” for further information on long-term debt. The Company’s carrying value and estimated fair value of the Company’s financial instruments, carried at adjusted historical cost, were as follows (in millions): December 31, 2021 December 31, 2020 Level Fair Value Carrying Value Fair Value Carrying Value Financial Instrument: 2022 Notes and 2023 Notes 1 $ 325.6 $ 322.3 $ 468.6 $ 471.9 2024 Secured Notes and 2025 Notes 2 $ 815.3 $ 742.0 $ 780.8 $ 739.6 Revolving credit facility 3 $ — $ (2.0) $ 108.0 $ 104.8 MRL Credit Facility 3 $ 303.5 $ 296.2 $ — $ — Shreveport terminal asset financing arrangement 3 $ 64.3 $ 63.0 $ — $ — Finance leases and other obligations 3 $ 4.7 $ 4.7 $ 6.0 $ 6.0

Equity [Abstract]
Partners' Capital	Partners’ Capital (Deficit) Units Authorized As of December 31, 2021 and 2020, the Company has 91,073,023 of common units authorized for issuance. Units Outstanding Of the 78,676,262 co mmon units outstanding at December 31, 2021 , 62,022,927 common units were held by the public, with the remaining 16,653,335 common units held by the Company’s affiliates (including members of the Company’s general partner and their families). Significant information regarding rights of the limited partners includes the following: • Rights to receive distributions of available cash within 45 days after the end of each quarter, to the extent the Company has sufficient cash from operations after the establishment of cash reserves. • Limited partners have limited voting rights on matters affecting the Company’s business. The general partner may consider only the interests and factors that it desires and has no duty or obligation to give any consideration of any interests of the Company’s limited partners. Limited partners have no right to elect the board of directors of the Company’s general partner. • The vote of the holders of at least 66 2/3% of all outstanding units voting together as a single class is required to remove the general partner. Any holder, other than the general partner or the general partner’s affiliates, that owns 20% or more of any class of units outstanding cannot vote on any matter. • The Company may issue an unlimited number of limited partner interests without the approval of the limited partners. • Limited partners may be required to sell their units to the general partner if at any time the general partner owns more than 80% of the issued and outstanding common units. Distributions and Incentive Distribution Rights The Company’s general partner is entitled to incentive distributions if the amount it distributes to unitholders with respect to any quarter exceeds specified target levels shown below: Total Quarterly Marginal Percentage Target Amount Unitholders General Partner Minimum Quarterly Distribution $0.45 98 % 2 % First Target Distribution up to $0.495 98 % 2 % Second Target Distribution above $0.495 up to $0.563 85 % 15 % Third Target Distribution above $0.563 up to $0.675 75 % 25 % Thereafter above $0.675 50 % 50 % The Company’s ability to make distributions is limited by its debt instruments. The revolving credit facility generally permits the Company to make cash distributions to unitholders as long as immediately after giving effect to such a cash distribution the Company has availability under the revolving credit facility at least the greater of (i) 15% of the Aggregate Borrowing Base (as defined in the credit agreement) then in effect, and (ii) $60.0 million (which amount is subject to increase in proportion to revolving commitment increases). Further, the revolving credit facility contains one springing financial covenant which provides that only if the Company’s availability under the revolving credit facility falls below the greater of (a) 10.0% of the Borrowing Base (as defined in the credit agreement) then in effect, and (b) $35.0 million (which amount is subject to increase in proportion to revolving commitment increases), the Company will be required to maintain as of the end of each fiscal quarter a Fixed Charge Coverage Ratio (as defined in the credit agreement) of at least 1.0 to 1.0. The indentures governing the Company’s various senior notes restrict the Company’s ability to make cash distributions. Under the indenture governing the 2023 Notes, the Company may pay distributions to its unitholders in an amount equal to available cash from operating surplus (as defined in the Company’s partnership agreement) with respect to its preceding fiscal quarter, subject to certain customary adjustments described in the indentures, if the Company’s fixed charge coverage ratio (as defined in the indentures) for the most recently ended four full fiscal quarters is not less than 1.75 to 1.0. If the Company’s fixed charge coverage ratio is less than 1.75 to 1.0, the Company will be able to pay distributions to its unitholders up to an amount equal to a $225.0 million basket, subject to certain customary adjustments described in the indentures. The indentures governing the 2024 Secured Notes and 2025 Notes increase this minimum fixed charge coverage ratio to 3.0 to 1.0, with a basket of $25.0 million if the minimum is not met, also subject to certain customary adjustments described in the indentures.

Share-based Payment Arrangement [Abstract]
Unit-Based Compensation	Unit-Based Compensation The Company’s general partner originally adopted a Long-Term Incentive Plan on January 24, 2006, which was amended and restated effective December 10, 2015 and further amended effective December 9, 2021 (the “LTIP”), for its employees, consultants and directors and its affiliates who perform services for the Company. The LTIP provides for the grant of restricted units, phantom units, unit options and substitute awards and, with respect to unit options and phantom units, the grant of distribution equivalent rights (“DERs”). Following unitholder approval of the December 9, 2021 amendment to the LTIP, which was obtained on February 16, 2022, an aggregate of 5,283,960 common units may be delivered pursuant to awards under the LTIP. Units withheld to satisfy the Company’s general partner’s tax withholding obligations are available for delivery pursuant to other awards. The LTIP is administered by the compensation committee of the Company’s general partner’s board of directors. Liability Awards are awards that are currently expected to be settled in cash on their vesting dates, rather than in equity units. Phantom unit Liability Awards are recorded in accrued salaries, wages and benefits in the consolidated balance sheets based on the vested portion of the fair value of the awards on the balance sheet date. The fair value of Liability Awards is updated at each balance sheet date and changes in the fair values of the vested portions of the awards are recorded as increases or decreases to compensation expense within general and administrative expense in the consolidated statements of operations. Phantom Units Non-employee directors and certain management level employees of the Company’s general partner have been granted phantom units under the terms of the LTIP as part of their respective compensation packages related to fiscal years 2021 and 2020. The phantom units granted to non-employee directors related to fiscal year 2021 have a three-year cliff vest on the third anniversary following the grant date. The phantom units granted to non-employee directors related to fiscal year 2020 have a three Non-employee directors and certain senior management level employees of the Company’s general partner are eligible to defer their earned director fees or earned annual cash incentive amounts, respectively, into the Deferred Compensation Plan. When such individuals elect to defer any portion of their compensation into the plans, these deferred amounts are credited to the participant in the form of phantom units. The compensation committee may recommend a matching contribution for the deferred amounts at its discretion. For unit-based compensation equity awards granted, the Company uses the market price of its common units on the grant date to calculate the fair value and related compensation cost of the phantom units. The Company amortizes this compensation cost to partners’ capital (deficit) and general and administrative expense in the consolidated statements of operations using the straight-line method over the service period, as it expects these units to fully vest. A summary of the Company’s non-vested phantom units as of December 31, 2021, and the changes during the years ended December 31, 2021 and 2020, are presented below: Number of Weighted-Average Non-vested at December 31, 2019 2,901,288 $ 5.21 Granted 3,210,041 2.87 Vested (2,191,846) 3.11 Forfeited (1,548,615) 4.28 Non-vested at December 31, 2020 2,370,868 $ 2.21 Granted 821,964 4.71 Vested (1,002,338) 3.34 Forfeited (61,933) 3.68 Non-vested at December 31, 2021 2,128,561 $ 2.31 For the year ended December 31, 2021, compensation expense of $50.7 million was recognized in the consolidated statements of operations related to phantom unit grants, including $48.9 million attributable to Liability Awards for the year ended December 31, 2021. For the year ended December 31, 2020, compensation expense of $5.5 million was recognized in the consolidated statements of operations related to phantom unit grants, including $4.5 million attributable to Liability Awards for the year ended December 31, 2020. As of December 31, 2021, there was a total of $4.9 million of unrecognized compensation costs related to non-vested phantom unit grants, all of which was attributable to Liability Awards. As of December 31, 2020, there was a total of $5.2 million of unrecognized compensation costs related to non-vested phantom unit grants. These costs are expected to be recognized over a weighted-average period of approximately one $11.7 million and $5.3 million, respectively.

Retirement Benefits [Abstract]
Compensation and Employee Benefit Plans	Employee Benefit Plans Defined Contribution Plan The Company has a domestic defined contribution plan administered by its general partner for (i) all full-time employees that are eligible to participate in the plan (the “401(k) Plan”). Participants in the 401(k) Plan are allowed to contribute 1% to 70% of their pre-tax earnings to the plan, subject to government imposed limitations. The Company matches 100% of each 1% of eligible compensation contributed by the participant up to 4% and 50% of each additional 1% of eligible compensation contributed up to 6%, for a maximum contribution by the Company of 5% of eligible compensation contributed per participant. The plan also includes a profit-sharing component for eligible employees. Contributions under the profit-sharing component are determined by the board of directors of the Company’s general partner and are discretionary. The funding policy is consistent with funding requirements of applicable laws and regulations. The Company recorded the following 401(k) Plan matching contribution expense in the consolidated statements of operations (in millions): Year Ended December 31, 2021 2020 401(k) Plan matching contribution expense $ 5.9 $ 5.6 Defined Benefit Pension Plan The Company has domestic noncontributory defined benefit plans for those salaried employees as well as those employees represented by either the United Steelworkers (the “USW”) or the International Union of Operating Engineers (the “IUOE”); who (i) were formerly employees of Penreco and became employees of the Company as a result of the acquisition of Penreco on January 3, 2008 (the “Penreco Pension Plan”) or (ii) were formerly employees of Montana Refining Company, Inc. and who became employees of the Company as a result of the acquisition of the Great Falls refinery on October 1, 2012 (the “Great Falls Pension Plan” and together with the Penreco Pension Plan, the “Pension Plan”). Both the Penreco Pension Plan and the Great Falls Pension Plans were last amended in 2009 and 2015 respectively, which curtailed employees covered by the plans from accumulating additional benefits in subsequent years following the amendment date. During 2021, th e Company made an immaterial amount of contributions to its Pension Plan a nd expects to contribute less than $0.1 million to its Pension Plan in 2022. The accumulated and projected benefit obligations for the Pension Plan were $41.2 million and $43.6 million as of December 31, 2021 and 2020, respectively. For the years ended December 31, 2021 and 2020, the discount rate used to determine the benefit obligatio ns was 2.72% and 2.34%, respectively, for the Penreco Pension Plan and 2.70% and 2.35%, respectively, for the Gre at Falls Pension Plan. For the years ended December 31, 2021 and 2020, the expected return on plan assets for the Penreco Pension Plan and Great Falls Pension Plan was 4.50% and 5.00%, respectively . The fair value of plan assets was $34.5 million and $34.4 million a s of December 31, 2021 and 2020, respectively. The estimated benefit payments for the Pension Plan, which reflect expected future service, as appropriate, are expected to be l ess than $2.3 million in each of the next five years.

Segments and Related Informatio

Segments and Related Information (Notes)	12 Months Ended

Segment Reporting [Abstract]
Segments and Related Information	Segments and Related Information Segment Reporting The Company determines its reportable segments based on how the business is managed internally for the products sold to customers, including how results are reviewed and resources are allocated by the chief operating decision makers (“CODM”). Effective January 1, 2021, the Company reorganized its business segments as a result of a change in how the CODM allocates resources, makes operating decisions and assesses the performance of its business. As a result, as of January 1, 2021, the Company’s operations are managed by the CODM using the following reportable segments: • Specialty Products and Solutions. The Specialty Products and Solutions segment consists of our customer-focused solutions and formulations businesses, covering multiple specialty product lines, anchored by our unique integrated complex in Northwest Louisiana. In this segment, we manufacture and market a wide variety of solvents, waxes, customized lubricating oils, white oils, petrolatums, gels, esters, and other products. Our specialty products are sold to domestic and international customers who purchase them primarily as raw material components for consumer-facing and industrial products. • Montana/Renewables. The Montana/Renewables segment is composed of our Great Falls refinery and dual-train energy transition project. When our Great Falls renewable diesel facility is operational, we will process a variety of geographically advantaged renewable feedstocks into renewable hydrogen, renewable natural gas, renewable propane, renewable naphtha, renewable kerosene/aviation fuel, and renewable diesel that we expect to distribute into renewable markets in the western half of North America. At our Montana specialty refinery, we process Canadian crude oil into conventional gasoline, diesel, jet fuel and specialty grades of asphalt, with production sized to serve local markets. • Performance Brands. The Performance Brands segment includes our fast-growing portfolio of high-quality, high-performing brands. In this segment, we blend, package, and market high performance products through our Royal Purple, Bel-Ray, and TruFuel brands. • Corporate. The Corporate segment primarily consists of general and administrative expenses not allocated to the Montana/Renewables, Specialty Products and Solutions, or Performance Brands segments. Segment information presented herein reflects the impact of this reorganization for all periods presented. During the first quarter of 2021, the CODM changed the definition and calculation of Adjusted EBITDA to exclude RINs mark-to-market adjustments (see item (j) below). The Company’s RINs liability is calculated by multiplying the RINs shortage (based on actual results) by the period end spot price and is subsequently revalued as of the last day of each accounting period. The resulting non-cash adjustments are included in cost of sales in the statement of operations, with the exception of RINs for the 2019 compliance year related to the San Antonio refinery, which are included in other operating expense. The Company believes that this revised definition and calculation better reflects the performance of the Company’s business segments including cash flows because it excludes these non-cash fluctuations. Adjusted EBITDA has been revised for all periods presented to consistently reflect this change. The accounting policies of the reporting segments are the same as those described in the summary of significant accounting policies as disclosed in Note 3 - “Summary of Significant Accounting Policies,” except that the disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The Company accounts for inter-segment sales and transfers using market-based transfer pricing. The Company will periodically refine its expense allocation methodology for its segment reporting as more specific information becomes available and the industry or market changes. In addition, the accounting policies of the reporting segments for shipping and handling costs, which are primarily costs paid to third-party shippers for transporting products to customers, are the same as that described in Note 2 - “Change in Accounting Policy.” The Company evaluates performance based upon Adjusted EBITDA (a non-GAAP financial measure). The Company defines Adjusted EBITDA for any period as EBITDA adjusted for (a) impairment; (b) unrealized gains and losses from mark-to-market accounting for hedging activities; (c) realized gains and losses under derivative instruments excluded from the determination of net income (loss); (d) non-cash equity-based compensation expense and other non-cash items (excluding items such as accruals of cash expenses in a future period or amortization of a prepaid cash expense) that were deducted in computing net income (loss); (e) debt refinancing fees, extinguishment costs, premiums and penalties; (f) any net gain or loss realized in connection with an asset sale that was deducted in computing net income (loss); (g) amortization of turnaround costs; (h) LCM inventory adjustments; (i) the impact of liquidation of inventory layers calculated using the LIFO method; (j) RINs mark-to-market adjustments; and (k) all extraordinary, unusual or non-recurring items of gain or loss, or revenue or expense.

Major Suppliers During the years ended December 31, 2021 and 2020, the Company had two counterparties that supplied approximately 90.2% and 82.9% , respectively, of its crude oil supply.
Accounting Standards Update and Change in Accounting Principle	Change in Accounting Policy During the first quarter of fiscal 2021, the Company changed its method of accounting for shipping and handling costs, which are primarily costs paid to third-party shippers for transporting products to customers. Under the new method of accounting, the Company includes shipping costs in cost of sales, whereas previously, they were included in operating costs and expenses under the caption transportation expense. The Company believes that including these expenses in cost of sales is preferable, as it better aligns these costs with the related revenue in the gross profit calculation and is consistent with the practices of other industry peers. This change in accounting principle has been applied retrospectively, and the consolidated statements of operations reflect the effect of this accounting principle change for all periods presented. This reclassification had no impact on net income (loss) before income taxes, net income (loss) attributable to limited partners, limited partners’ interest basic net income (loss) per unit, or limited partners’ interest diluted net income (loss) per unit. The consolidated balance sheets, consolidated statements of comprehensive income (loss), consolidated statements of partners’ capital (deficit), and consolidated statements of cash flows were not impacted by this accounting principle change. The consolidated statements of operations for the year ended December 31, 2020 have been adjusted to reflect this change in accounting policy. The impact of the adjustment for the year ended December 31, 2020 was an increase of $111.0 million to cost of sales and a corresponding decrease to transportation expense in the consolidated statements of operations.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events As of March 1, 2022, the fair value of the Company’s derivative liabilities has increased by approximately $16.9 million subsequent to December 31, 2021. On January 20, 2022, the Company issued and sold $325.0 million in aggregate principal amount of 2027 Notes, in a private placement pursuant to Section 4(a)(2) of the Securities Act to eligible purchasers at par. The Company received net proceeds of $319.1 million, after deducting the initial purchasers’ discount and offering expenses. Interest on the 2027 Notes is paid semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2022. On January 12, 2022, the Company issued a notice of conditional redemption for $325.0 million in aggregate principal amount of the 2023 Notes at a redemption price of par, plus accrued and unpaid interest to the redemption date of February 11, 2022, conditioned on the completion of an offering of at least $300.0 million aggregate principal amount of senior debt securities on or before February 11, 2022. As the conditions precedent were met on January 20, 2022, the Company funded the redemption of the 2023 Notes with the net proceeds from the offering of the 2027 Notes and the remainder from cash on hand. In conjunction with the redemption, the Company incurred debt extinguishment costs of $2.5 million. On January 20, 2022, the Company entered into the Third Amendment to its revolving credit facility (the “Credit Facility Amendment”), which, among other chang es, (a) extends the term of the revolving credit facility for five years from the date of the Credit Facility Amendment, (b) reduces aggregate commitments under the revolving credit facility to $500.0 million, which includes a FILO tranche, and (c) replaces LIBOR as a reference interest rate with a new reference interest rate based on Secured Overnight Financing Rate.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Consolidation	The consolidated financial statements and related notes reflect the accounts of the Company and its wholly-owned subsidiaries. All intercompany profits, transactions and balances have been eliminated.
Reclassifications	Certain amounts in the prior years’ consolidated financial statements have been reclassified to conform to the current year presentation.
Use of Estimates	The Company’s consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash, Cash Equivalents and Restricted Cash	Cash, cash equivalents and restricted cash include all highly liquid investments with a maturity of three months or less at the time of purchase. Restricted cash represents cash that is legally restricted under the MRL Credit Facility, and it is presented as a non-current asset because it is only available for capital additions related to the renewable diesel project.
Accounts Receivable	The Company performs periodic credit evaluations of customers’ financial condition and generally does not require collateral. Accounts receivable are carried at their face amounts. The Company maintains an allowance for credit losses for estimated losses in the collection of accounts receivable. The Company makes estimates regarding the future ability of its customers to make required payments based on historical experience, the age of the accounts receivable balances, credit quality of its customers, current economic conditions, expected future trends and other factors that may affect customers’ ability to pay. Individual accounts are written off against the allowance for credit losses after all reasonable collection efforts have been exhausted.
Inventories	The cost of inventory is recorded using the last-in, first-out (“LIFO”) method. Costs include crude oil and other feedstocks, labor, processing costs and refining overhead costs. Inventories are valued at the lower of cost or market value. Under the LIFO inventory method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs.
Derivatives	The Company is exposed to fluctuations in the price of numerous commodities, such as crude oil (its principal raw material), as well as the sales prices of gasoline, diesel, natural gas and jet fuel. Given the historical volatility of commodity prices, these fluctuations can significantly impact sales, gross profit and net income. Therefore, the Company utilizes derivative instruments primarily to minimize its price risk and volatility of cash flows associated with the purchase of crude oil, natural gas, and the sale of fuel products. The Company employs various hedging strategies and does not hold or issue derivative instruments for trading purposes. Derivatives The Company is exposed to price risks due to fluctuations in the price of crude oil, refined products, natural gas and precious metals. The Company uses various strategies to reduce its exposure to commodity price risk. The strategies to reduce the Company’s risk utilize both physical forward contracts and financially settled derivative instruments, such as swaps, collars, options and futures, to attempt to reduce the Company’s exposure with respect to: • crude oil purchases and sales; • fuel product sales and purchases; • natural gas purchases; • precious metals purchases; and • fluctuations in the value of crude oil between geographic regions and between the different types of crude oil such as New York Mercantile Exchange West Texas Intermediate (“NYMEX WTI”), Light Louisiana Sweet, Western Canadian Select (“WCS”), WTI Midland, Mixed Sweet Blend, Magellan East Houston and ICE Brent. The Company manages its exposure to commodity markets, credit, volumetric and liquidity risks to manage its costs and volatility of cash flows as conditions warrant or opportunities become available. These risks may be managed in a variety of ways that may include the use of derivative instruments. Derivative instruments may be used for the purpose of mitigating risks associated with an asset, liability and anticipated future transactions and the changes in fair value of the Company’s derivative instruments will affect its earnings and cash flows; however, such changes should be offset by price or rate changes related to the underlying commodity or financial transaction that is part of the risk management strategy. The Company does not speculate with derivative instruments or other contractual arrangements that are not associated with its business objectives. Speculation is defined as increasing the Company’s natural position above the maximum position of its physical assets or trading in commodities, currencies or other risk bearing assets that are not associated with the Company’s business activities and objectives. The Company’s positions are monitored routinely by a risk management committee to ensure compliance with its stated risk management policy and documented risk management strategies. All strategies are reviewed on an ongoing basis by the Company’s risk management committee, which will add, remove or revise strategies in anticipation of changes in market conditions and/or its risk profiles. Such changes in strategies are to position the Company in relation to its risk exposures in an attempt to capture market opportunities as they arise. The Company is obligated to repurchase crude oil and refined products from Macquarie at the termination of the Supply and Offtake Agreements in certain scenarios. The Company has determined that the redemption feature on the initially recognized liability related to the Supply and Offtake Agreements is an embedded derivative indexed to commodity prices. As such, the Company has accounted for this embedded derivative at fair value with changes in the fair value, if any, recorded in gain (loss) on derivative instruments in the Company’s consolidated statements of operations please read Note 8 - “Inventory Financing Agreements" for additional information. The Company recognizes all derivative instruments at their fair values as either current assets or current liabilities in the consolidated balance sheets (please read Note 11 - “Fair Value Measurements”). Fair value includes any premiums paid or received and unrealized gains and losses. Fair value does not include any amounts receivable from or payable to counterparties, or collateral provided to counterparties. Derivative asset and liability amounts with the same counterparty are netted against each other for financial reporting purposes in accordance with the provisions of our master netting arrangements. The following tables summarize the Company’s gross fair values of its derivative instruments, presenting the impact of offsetting derivative assets in the Company’s consolidated balance sheets (in millions): December 31, 2021 December 31, 2020 Balance Sheet Location Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts of Assets Presented in the Consolidated Balance Sheets Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts of Assets Presented in the Consolidated Balance Sheets Derivative instruments not designated as hedges: Montana/Renewables segment: WCS crude oil basis swaps Prepaid expenses and other current assets $ — $ — $ — $ 0.4 $ (0.4) $ — Total derivative instruments $ — $ — $ — $ 0.4 $ (0.4) $ — The following tables summarize the Company’s gross fair values of its derivative instruments, presenting the impact of offsetting derivative liabilities in the Company’s consolidated balance sheets (in millions): December 31, 2021 December 31, 2020 Balance Sheet Location Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts of Liabilities Presented in the Consolidated Balance Sheets Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts of Liabilities Presented in the Consolidated Balance Sheets Derivative instruments not designated as hedges: Specialty Products and Solutions segment: Inventory financing obligation Obligations under inventory financing agreements $ (17.4) $ — $ (17.4) $ (1.1) $ — $ (1.1) Montana/Renewables segment: Inventory financing obligation Obligations under inventory financing agreements $ (10.5) $ — $ (10.5) $ (1.1) $ — $ (1.1) WCS crude oil basis swaps Derivative liabilities — — — (1.7) 0.4 (1.3) Total derivative instruments $ (27.9) $ — $ (27.9) $ (3.9) $ 0.4 $ (3.5) Certain of the Company’s outstanding derivative instruments are subject to credit support agreements with the applicable counterparties which contain provisions setting certain credit thresholds above which the Company may be required to post agreed-upon collateral, such as cash or letters of credit, with the counterparty to the extent that the Company’s mark-to-market net liability, if any, on all outstanding derivatives exceeds the credit threshold amount per such credit support agreement. The majority of the credit support agreements covering the Company’s outstanding derivative instruments also contain a general provision stating that if the Company experiences a material adverse change in its business, in the reasonable discretion of the counterparty, the Company’s credit threshold could be lowered by such counterparty. The Company does not expect that it will experience a material adverse change in its business. The cash flow impact of the Company’s derivative activities are included within cash flows from operating activities in the consolidated statements of cash flows. Derivative Instruments Not Designated as Hedges For derivative instruments not designated as hedges, the change in fair value of the asset or liability for the period is recorded to unrealized gain (loss) on derivative instruments in the consolidated statements of operations. Upon the settlement of a derivative not designated as a hedge, the gain or loss at settlement is recorded to realized gain (loss) on derivative instruments in the consolidated statements of operations. The Company has entered into natural gas swaps, crack spread swaps and crude oil basis swaps that are not designated as cash flow hedges for accounting purposes. However, these instruments provide economic hedges of the purchases and sales of the Company’s natural gas, crude oil, gasoline and refined products. The Company recorded the following gains (losses) in its consolidated statements of operations related to its derivative instruments not designated as hedges (in millions): Amount of Gain (Loss) Amount of Gain (Loss) Year Ended December 31, Year Ended December 31, Type of Derivative 2021 2020 2021 2020 Specialty Products and Solutions segment: Inventory financing obligation $ — $ — $ (16.3) $ 4.0 Natural gas swaps — 0.2 — — Crack spread swaps — 29.9 — (2.2) Montana/Renewables segment: Inventory financing obligation — — (9.4) 1.1 WCS crude oil basis swaps 1.1 19.5 1.3 (0.1) Total $ 1.1 $ 49.6 $ (24.4) $ 2.8 Derivative Positions As of December 31, 2021, the Company had no outstanding derivative contracts.
Property, Plant and Equipment	Property, plant and equipment are stated on the basis of cost. Depreciation is calculated using the straight-line method over the estimated useful lives. Assets under finance leases are amortized over the lesser of the useful life of the asset or the term of the lease.
Composite Depreciation Method	Under the composite depreciation method, the cost of partial retirements of a group is charged to accumulated depreciation. However, when there are dispositions of complete groups or significant portions of groups, the cost and related accumulated depreciation are retired, and any gain or loss is reflected in earnings.
Capitalized Software	The Company capitalizes the cost of computer software developed or obtained for internal use. Capitalized software is amortized using the straight-line method over five
Goodwill	Goodwill represents the excess of purchase price over fair value of the net assets acquired in various acquisitions. Please read Note 6 - “Goodwill and Other Intangible Assets” for more information. The Company assesses goodwill for impairment annually and whenever events or changes in circumstances indicate its carrying value may not be recoverable in accordance with ASC 350, Intangibles — Goodwill and Other (Topic 350) and ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . Under ASC 350, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the impairment test is unnecessary. The Company tests goodwill either quantitatively or qualitatively for impairment. The Company assessed goodwill for impairment qualitatively and quantitatively during the years ended December 31, 2021 and 2020, respectively. In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company assesses relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgment and assumptions. The judgment and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and Company specific events and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. In the first step of the quantitative assessment, the Company’s assets and liabilities, including existing goodwill and other intangible assets, are assigned to the identified reporting units to determine the carrying value of the reporting units. Under ASU 2017-04, goodwill impairment testing is done by comparing the fair value of the reporting unit to its carrying value. If the carrying amount exceeds the fair value, the Company would recognize an impairment charge for the amount that the reporting unit's carrying value exceeds the fair value, not to exceed the total amount of goodwill allocated to that reporting unit. Inputs used to estimate the fair value of the Company’s reporting units are considered Level 3 inputs of the fair value hierarchy and include the following: • The Company’s financial projections for its reporting units are based on its analysis of various supply and demand factors which include, among other things, industry-wide capacity, its planned utilization rate, end-user demand, crack spreads, capital expenditures and economic conditions. Such estimates are consistent with those used in the Company’s planning and capital investment reviews and include recent historical prices and published forward prices. • The discount rate used to measure the present value of the projected future cash flows is based on a variety of factors, including market and economic conditions, operational risk, regulatory risk and political risk. This discount rate is also compared to recent observable market transactions, if possible. For Level 3 measurements, significant increases or decreases in long-term growth rates or discount rates in isolation or in combination could result in a significantly lower or higher fair value measurement.
Definite-Lived Intangible Assets	Finite-lived intangible assets consist of intangible assets associated with customer relationships, tradenames, trade secrets, patents and royalty agreements that were acquired in various acquisitions. The majority of these assets are being amortized using undiscounted estimated future cash flows over the term of the related agreements. Intangible assets associated with customer relationships are being amortized using the undiscounted estimated future cash flows method based upon assumed rates of annual customer attrition.Tradenames, trade secrets, patents and royalty agreements are being amortized to properly match expenses with the undiscounted estimated future cash flows over the terms of the related agreements or the period expected to be benefited. The costs of agreements with terms allowing for the potential extension of such agreements are being amortized based on the initial term only. Customer relationships are being amortized to properly match expenses with the undiscounted estimated future cash flows based upon assumed rates of annual customer attrition.
Impairment of Long-Lived Assets	The Company periodically evaluates the carrying value of long-lived assets to be held and used, including finite-lived intangible assets, when events or circumstances warrant such a review. The carrying value of a long-lived asset to be held and used is considered impaired when the anticipated separately identifiable undiscounted cash flows from such an asset are less than the carrying value of the asset. In such an event, a write-down of the asset would be recorded through a charge to operations, based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using anticipated cash flows assumed by a market participant discounted at a rate commensurate with the risk involved. Long-lived assets to be disposed of other than by sale are considered held and used until disposal.
Revenue Recognition	The Company recognizes revenue in accordance with ASC 606, Revenue Recognition,
Concentrations of Credit Risk	The Company performs periodic credit evaluations of its customers’ financial condition and in some instances requires cash in advance or letters of credit prior to shipment for domestic orders. For international orders, letters of credit are generally required, and the Company maintains insurance policies which cover certain export orders. The Company maintains an allowance for credit losses account for estimated losses resulting from the inability of its customers to make required payments. The allowance for credit losses is developed based on several factors including historical experience, the age of the accounts receivable balances, credit quality of the Company’s customers, current economic conditions, expected future trends and other factors that may affect customers’ ability to pay, which exist as of the balance sheet dates. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has derivative positions with a limited number of counterparties. The evaluation of these counterparties is performed quarterly in connection with the Company’s ASC 820-10, Fair Value Measurements and Disclosures, valuations to determine the impact of the counterparty credit risk on the valuation of its derivative instruments.
Earnings Per Unit	The Company calculates earnings per unit under ASC 260-10, Earnings per Share . The Company treats incentive distribution rights (“IDRs”) as participating securities for the purposes of computing earnings per unit in the period that the general partner becomes contractually obligated to receive IDRs. Also, the undistributed earnings are allocated to the partnership interests based on the allocation of earnings to the Company’s partners’ capital accounts as specified in the Company’s partnership agreement. When distributions exceed earnings, net income is reduced by the actual distributions with the resulting net loss being allocated to capital accounts as specified in the Company’s partnership agreement.
Unit-Based Compensation	For unit-based compensation equity awards granted, compensation expense is recognized in the Company’s consolidated financial statements on a straight-line basis over the awards’ vesting periods based on their fair values on the dates of grant. The unit-based compensation awards vest over a period not exceeding four years. The amount of compensation expense recognized at any date is at least equal to the portion of the grant date value of the award that is vested at that dateUnit-based compensation liability awards are awards that are currently expected to be settled in cash on their vesting dates, rather than in equity units (“Liability Awards”). Liability Awards are recorded in accrued salaries, wages and benefits based on the vested portion of the fair value of the awards on the balance sheet date. The fair value of Liability Awards is updated at each balance sheet date and changes in the fair value of the vested portions of the Liability Awards are recorded as increases or decreases to compensation expense. The Company recognizes forfeitures as they occur.Liability Awards are awards that are currently expected to be settled in cash on their vesting dates, rather than in equity units. Phantom unit Liability Awards are recorded in accrued salaries, wages and benefits in the consolidated balance sheets based on the vested portion of the fair value of the awards on the balance sheet date. The fair value of Liability Awards is updated at each balance sheet date and changes in the fair values of the vested portions of the awards are recorded as increases or decreases to compensation expense within general and administrative expense in the consolidated statements of operations.For unit-based compensation equity awards granted, the Company uses the market price of its common units on the grant date to calculate the fair value and related compensation cost of the phantom units. The Company amortizes this compensation cost to partners’ capital (deficit) and general and administrative expense in the consolidated statements of operations using the straight-line method over the service period, as it expects these units to fully vest.
Advertising Costs	Advertising expenses are reported as selling expenses in the consolidated statements of operations
New Accounting Pronouncements	On January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which changed the impairment model for most financial instruments. Previous guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflects losses once the losses are probable. Under ASU 2016-13, the Company is required to use a current expected credit loss (“CECL”) model that immediately recognizes an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of the update, including trade receivables. The CECL model uses a broader range of reasonable and supportable information in the development of credit loss estimates. The result of the adoption of ASU 2016-13 was de-minimis and did not result in an adjustment to beginning partners’ capital (deficit). The allowance for credit losses for accounts receivable was $2.0 million and $0.8 million at December 31, 2021 and 2020, respectively.
Turnaround Costs, Policy	Turnaround costs represent capitalized costs associated with the Company’s periodic major maintenance and repairs
Turnaround Costs Capitalization, Policy	The Company capitalizes these costs and amortizes the costs on a straight-line basis over the lives of the turnaround assets which is generally two five
RINs, Policy	The Company’s RINs obligation (“RINs Obligation”) is an estimated provision for the future purchase of RINs in order to satisfy the U.S. Environmental Protection Agency’s (“EPA”) requirement to blend renewable fuels into certain transportation fuel products pursuant to the Renewable Fuel Standard (“RFS”). A RIN is a 38-character number assigned to each physical gallon of renewable fuel produced in or imported into the United States. The EPA sets annual volume obligations for the percentage of renewable fuels that must be blended into transportation fuels consumed in the U.S. and, as a producer of transportation fuels from petroleum, the Company is subject to those obligations. Compliance is demonstrated by tendering RINs to the EPA documenting that blending has been accomplished. To the extent the Company is unable to physically blend renewable fuels to satisfy the EPA requirement, it may purchase RINs in the open market to satisfy the annual obligations. The Company accounts for its current period RINs obligation by multiplying the quantity of RINs shortage (based on actual results) by the period end RINs spot price, which is recorded as a RINs obligation in the consolidated balance sheets. The Company’s RINs obligations for compliance years 2019 and 2020 are presented as a current liability in the consolidated balance sheets and the Company’s RINs obligation for compliance year 2021 is presented as a long-term liability in the consolidated balance sheets. This liability is revalued at the end of each subsequent accounting period, which produces non-cash mark-to-market adjustments that are reflected in cost of sales in the consolidated statements of operations (with the exception of RINs for compliance year 2019 related to the San Antonio refinery, which amount is reflected in other operating expense in the consolidated statements of operations). RINs generated by blending may be sold or held to offset future RINs Obligations. Any gains or losses from RINs sales are recorded in cost of sales in the consolidated statements of operations. The liabilities associated with the Company’s RINs obligation are considered recurring fair value measurements. Please read Note 7 - “Commitments and Contingencies” for further information on the Company’s RINs Obligation.

Revenue from Contract with Cust

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	The following is a description of principal activities from which the Company generates revenue. Revenues are recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines the performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. For each contract, the Company considers the promise to transfer products, each of which are distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to variable consideration such as product returns, rebates or other discounts to determine the net consideration to which the Company expects to be entitled. The Company transfers control and recognizes revenue upon shipment to the customer or, in certain cases, upon receipt by the customer in accordance with contractual terms. Revenue is recognized when obligations under the terms of a contract with a customer are satisfied and control of the promised goods are transferred to the customer. The contract with the customer states the final terms of the sale, including the description, quantity and price of each product or service purchased. For fuel products, payment is typically due in full between 2 to 30 days of delivery or the start of the contract term, such that payment is typically collected 2 to 30 days subsequent to the satisfaction of performance obligations. For specialty products, payment is typically due in full between 30 to 90 days of delivery or the start of the contract term, such that payment is typically collected 30 to 90 days subsequent to the satisfaction of performance obligations. In the normal course of business, the Company does not accept product returns unless the item is defective as manufactured. The expected costs associated with a product assurance warranty continues to be recognized as expense when products are sold. The Company does not offer promised services that could be considered warranties that are sold separately or provide a service in addition to assurance that the related product complies with agreed upon specifications. The Company establishes provisions based on the methods described in ASC 606 for estimated returns and warranties as variable consideration when determining the transaction price.
Revenue, Transaction Price Measurement, Tax Exclusion [Policy Text Block]	The Company assesses, collects and remits excise taxes associated with the sale of certain of its fuel products. Furthermore, the Company collects and remits sales taxes associated with certain sales of its products to non-exempt customers. The Company excludes excise taxes and sales taxes that are collected from customers from the transaction price in its contracts with customers. Accordingly, revenue from contracts with customers is net of sales-based taxes that are collected from customers and remitted to taxing authorities.

Fair Value Disclosures [Abstract]
Fair Value Measurement, Policy	The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. These tiers include the following: • Level 1 — inputs include observable unadjusted quoted prices in active markets for identical assets or liabilities • Level 2 — inputs include other than quoted prices in active markets that are either directly or indirectly observable • Level 3 — inputs include unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions In determining fair value, the Company uses various valuation techniques and prioritizes the use of observable inputs. The availability of observable inputs varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded and other characteristics particular to the instrument. For many financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants and the valuation does not require significant management judgment. For other financial instruments, pricing inputs are less observable in the marketplace and may require management judgment.

Segment Reporting [Abstract]
Segment Reporting, Policy [Policy Text Block]	The accounting policies of the reporting segments are the same as those described in the summary of significant accounting policies as disclosed in Note 3 - “Summary of Significant Accounting Policies,” except that the disaggregated financial results for the reporting segments have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting internal operating decisions. The Company accounts for inter-segment sales and transfers using market-based transfer pricing. The Company will periodically refine its expense allocation methodology for its segment reporting as more specific information becomes available and the industry or market changes. In addition, the accounting policies of the reporting segments for shipping and handling costs, which are primarily costs paid to third-party shippers for transporting products to customers, are the same as that described in Note 2 - “Change in Accounting Policy.” The Company evaluates performance based upon Adjusted EBITDA (a non-GAAP financial measure). The Company defines Adjusted EBITDA for any period as EBITDA adjusted for (a) impairment; (b) unrealized gains and losses from mark-to-market accounting for hedging activities; (c) realized gains and losses under derivative instruments excluded from the determination of net income (loss); (d) non-cash equity-based compensation expense and other non-cash items (excluding items such as accruals of cash expenses in a future period or amortization of a prepaid cash expense) that were deducted in computing net income (loss); (e) debt refinancing fees, extinguishment costs, premiums and penalties; (f) any net gain or loss realized in connection with an asset sale that was deducted in computing net income (loss); (g) amortization of turnaround costs; (h) LCM inventory adjustments; (i) the impact of liquidation of inventory layers calculated using the LIFO method; (j) RINs mark-to-market adjustments; and (k) all extraordinary, unusual or non-recurring items of gain or loss, or revenue or expense.

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets For the years ended December 31, 2021 and 2020, the Company performed its annual goodwill assessment for each of the years then ended, respectively, and determined that the fair value of each of its reporting units with goodwill exceeded its carrying value. Thus, no impairment charge for goodwill related to the Specialty Products and Solutions segment or Performance Brands segment was recorded in the consolidated statements of operations within asset impairment for the years ended December 31, 2021 and 2020, respectively. There is no goodwill within the reporting units for the Montana/Renewables segment or the Corporate segment. Inputs used to estimate the fair value of the Company’s reporting units are considered Level 3 inputs of the fair value hierarchy and include the following: • The Company’s financial projections for its reporting units are based on its analysis of various supply and demand factors which include, among other things, industry-wide capacity, its planned utilization rate, end-user demand, crack spreads, capital expenditures and economic conditions. Such estimates are consistent with those used in the Company’s planning and capital investment reviews and include recent historical prices and published forward prices. • The discount rate used to measure the present value of the projected future cash flows is based on a variety of factors, including market and economic conditions, operational risk, regulatory risk and political risk. This discount rate is also compared to recent observable market transactions, if possible. For Level 3 measurements, significant increases or decreases in long-term growth rates or discount rates in isolation or in combination could result in a significantly lower or higher fair value measurement. Changes in goodwill balances for the periods indicated below are as follows (in millions): Specialty Performance Brands Consolidated Total Net balance as of December 31, 2019 $ 47.7 $ 123.7 $ 171.4 Additions 1.6 — 1.6 Impairment (1) — — — Net balance as of December 31, 2020 $ 49.3 $ 123.7 $ 173.0 Additions — — — Impairment (1) — — — Net balance as of December 31, 2021 $ 49.3 $ 123.7 $ 173.0 (1) Total accumulated goodwill impairment as of December 31, 2021 and 2020, is $35.5 million.

The costs of agreements with terms allowing for the potential extension of such agreements are being amortized based on the initial term only. Customer relationships are being amortized to properly match expenses with the undiscounted estimated future cash flows based upon assumed rates of annual customer attrition. For the years ended December 31, 2021 and 2020, the Company recorded amortization expense of intangible ass ets of $11.8 million and $14.3 million , respectively. As of December 31, 2021, the Company estimates that amortization of intangible assets for the next five years will be as follows (in millions): Year Amortization Amount 2022 $ 9.5 2023 $ 7.8 2024 $ 6.5 2025 $ 4.9 2026 $ 3.8
