Basis of Presentation, Description of Business and Summary of Significant Accounting Policies	1. BASIS OF PRESENTATION, DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization References to “the partnership” in the consolidated financial statements and notes to the consolidated financial statements refer to Green Plains Partners LP and its subsidiaries. Green Plains Holdings LLC, a wholly owned subsidiary of Green Plains Inc., serves as the general partner of the partnership. References to (i) “the general partner” and “Green Plains Holdings” refer to Green Plains Holdings LLC; (ii) “the parent,” “the sponsor” and “Green Plains” refer to Green Plains Inc.; and (iii) “Green Plains Trade” refers to Green Plains Trade Group LLC, a wholly owned subsidiary of Green Plains. Consolidated Financial Statements The consolidated financial statements include the accounts of the partnership and its controlled subsidiaries. All significant intercompany balances and transactions are eliminated on a consolidated basis for reporting purposes. Results for the interim periods presented are not necessarily indicative of the expected results for the entire year. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and footnotes required by GAAP, the consolidated financial statements should be read in conjunction with the partnership’s 2019 annual report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on February 20, 2020. The partnership accounts for its interest in joint ventures using the equity method of accounting, with its investment recorded at the acquisition cost plus the partnership’s share of equity in undistributed earnings and reduced by the partnership’s share of equity in undistributed losses and distributions received. Use of Estimates in the Preparation of Consolidated Financial Statements Preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and revenues and expenses during the reporting period. The partnership bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances. The partnership regularly evaluates the appropriateness of these estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including, but not limited to, those related to revenue recognition, depreciation of property and equipment, asset retirement obligations, operating leases, and impairment of long-lived assets and goodwill, are impacted significantly by judgments, assumptions and estimates used to prepare the consolidated financial statements. Description of Business The partnership provides fuel storage and transportation services by owning, operating, developing and acquiring ethanol and fuel storage terminals, transportation assets and other related assets and businesses. The partnership is its parent’s primary downstream logistics provider to support the parent’s approximately 1.1 bgy ethanol marketing and distribution business since the partnership’s assets are the principal method of storing and delivering the ethanol its parent produces. The ethanol produced by the parent is predominantly fuel grade, made principally from starch extracted from corn, and is primarily used for blending with gasoline. Ethanol currently comprises approximately 10 % of the U.S. gasoline market and is an economical source of octane and oxygenates for blending into the fuel supply. The partnership does not take ownership of, or receive any payments based on the value of the ethanol, other fuels or products it handles. As a result, the partnership does not have any direct exposure to fluctuations in commodity prices. Revenue Recognition The partnership recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the completion of services or the transfer of control of products to the customer or another specified third party. Operating lease revenue related to minimum volume commitments is recognized on a straight-line basis over the term of the lease. Under the terms of the storage and throughput agreement with Green Plains Trade, to the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred. The partnership generates a substantial portion of its revenues under fee-based commercial agreements with Green Plains Trade. Please refer to Note 2 - Revenue to the consolidated financial statements for further details. Operations and Maintenance Expenses The partnership’s operations and maintenance expenses consist primarily of lease expenses related to the transportation assets, labor expenses, outside contractor expenses, insurance premiums, repairs and maintenance expenses, and utility costs. These expenses also include fees for certain management, maintenance and operational services to support the storage and terminal facilities, trucks, and leased railcar fleet allocated by Green Plains under the operational services and secondment agreement. Concentrations of Credit Risk In the normal course of business, the partnership is exposed to credit risk resulting from the possibility a loss may occur due to failure of another party to perform according to the terms of their contract. The partnership provides fuel storage and transportation services for various parties with a significant portion of its revenues earned from Green Plains Trade. The partnership continually monitors its credit risk exposure and concentrations. Please refer to Note 2 – Revenue and Note 11 – Related Party Transactions to the consolidated financial statements for additional information . Segment Reporting The partnership accounts for segment reporting in accordance with ASC 280, Segment Reporting , which establishes standards for entities reporting information about the operating segments and geographic areas in which they operate. Management evaluated how its chief operating decision maker has organized the partnership for purposes of making operating decisions and assessing performance, and concluded it has one reportable segment. Asset Retirement Obligations The partnership records an ARO for the fair value of the estimated costs to retire a tangible long-lived asset in the period incurred if it can be reasonably estimated, which is subsequently adjusted for accretion expense. Corresponding asset retirement costs are capitalized as a long-lived asset and depreciated on a straight-line basis over the asset’s remaining useful life. The expected present value technique used to calculate the fair value of the AROs includes assumptions about costs, settlement dates, interest accretion, and inflation. Changes in assumptions, such as the amount or timing of estimated cash flows, could increase or decrease the AROs. The partnership’s AROs are based on legal obligations to perform remedial activity related to land, machinery and equipment when certain operating leases expire. Please refer to Note 5 – Asset Retirement Obligations to the consolidated financial statements for additional information. Recent Accounting Pronouncements In March 2020, the FASB issued amended guidance in ASC 848, Reference Rate Reform Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The expedients and exceptions provided by the amended guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The guidance is effective upon issuance and to be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The amended guidance is not expected to have a material impact on the partnership’s consolidated financial statements.

Revenue [Abstract]
Revenue	2. REVENUE Revenue Recognition The partnership recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the completion of services or the transfer of control of products to the customer or another specified third party. Revenue is measured as the amount of consideration expected to be received in exchange for providing services. Revenue by Source The following table disaggregates our revenue by major source (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Revenues Service revenues Terminal services $ 2,047 $ 2,150 $ 6,147 $ 7,045 Trucking and other 1,162 1,171 3,420 3,188 Total service revenues 3,209 3,321 9,567 10,233 Leasing revenues (1) Storage and throughput services 12,520 11,785 36,090 35,355 Railcar transportation services 5,538 5,005 16,036 16,129 Terminal services 115 43 341 349 Total leasing revenues 18,173 16,833 52,467 51,833 Total revenues $ 21,382 $ 20,154 $ 62,034 $ 62,066 (1) Leasing revenues do not represent revenues recognized from contracts with customers under ASC 606, Revenue from Contracts with Customers , and are accounted for under ASC 842, Leases . Terminal Services Revenue The partnership provides terminal services and logistics solutions to Green Plains Trade, and other customers, through its fuel terminal facilities under various terminal service agreements, some of which have minimum volume commitments. Revenue generated by these terminals is disaggregated between service revenue and leasing revenue. If Green Plains, or other customers, fail to meet their minimum volume commitments during the applicable term, a deficiency payment equal to the deficient volume multiplied by the applicable fee will be charged. Deficiency payments related to the partnership’s terminal services revenue may not be utilized as credits toward future volumes. At terminals where customers have shared use of terminal and tank storage assets, revenue is generated from contracts with customers and accounted for as service revenue. This service revenue is recognized at the point in time when product is withdrawn from tank storage. At terminals where a customer is predominantly provided exclusive use of the terminal or tank storage assets, the partnership is considered a lessor as part of an operating lease agreement. Revenue is recognized over the term of the lease based on the minimum volume commitment or total actual throughput if in excess of the minimum volume commitment. Trucking and Other Revenue The partnership transports ethanol, natural gasoline, other refined fuels and feedstocks by truck from identified receipt points to various delivery points. Trucking revenue is recognized over time based on the percentage of total miles traveled, which is on average less than 100 miles. Railcar Transportation Services Revenue Under the rail transportation services agreement, Green Plains Trade is obligated to use the partnership to transport ethanol and other fuels from receipt points identified by Green Plains Trade to nominated delivery points. Green Plains Trade is required to pay the partnership fees for the minimum railcar volumetric capacity provided, regardless of utilization of that capacity. However, Green Plains Trade is not charged for railcar volumetric capacity that is not available for use due to inspections, upgrades or routine repairs and maintenance. Revenue associated with the rail transportation services fee is considered leasing revenue and is recognized over the term of the lease based on the actual average daily railcar volumetric capacity provided. The partnership may also charge Green Plains Trade a related services fee for logistical operations management of railcar volumetric capacity utilized by Green Plains Trade which is not provided by the partnership. Revenue associated with the related services fee is also considered leasing revenue and recognized over the term of the lease based on the average volumetric capacity for which services are provided. Storage and Throughput Revenue The partnership generates leasing revenue from its storage and throughput agreement with Green Plains Trade based on contractual rates charged for the handling, storage and throughput of ethanol. Under this agreement, Green Plains Trade is required to pay the partnership a fee for a minimum volume commitment regardless of the actual volume delivered. If Green Plains Trade fails to meet its minimum volume commitment during any quarter, the partnership will charge Green Plains Trade a deficiency payment equal to the deficient volume multiplied by the applicable fee. The deficiency payment may be applied as a credit toward volumes delivered by Green Plains Trade in excess of the minimum volume commitment during the following four quarters, after which time any unused credits will expire. Revenue is recognized over the term of the lease based on the minimum volume commitment or total actual throughput if in excess of the minimum volume commitment and no deficiency related credits are available for use. Payment Terms The partnership has standard payment terms, which vary depending on the nature of the services provided, with the majority of terms falling within 10 to 30 days after transfer of control or completion of services. Contracts generally do not include a significant financing component in instances where the timing of revenue recognition differs from the timing of invoicing. Major Customers Revenue from Green Plains Trade Group was $ 20.3 million and $ 58.3 million for the three and nine months ended September 30, 2020, respectively, and $ 18.8 million and $ 56.8 million for the three and nine months ended September 30, 2019, respectively, which exceeds 10 % of the partnership’s total revenue. Contract Liabilities The partnership records unearned revenue when consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of service and lease agreements. Unearned revenue from service agreements, which represents a contract liability, is recorded for fees that have been charged to the customer prior to the completion of performance obligations, and is generally recognized in the subsequent quarter. The following table reflects the changes in our unearned revenue from service agreements, which is recorded in accrued and other liabilities on the consolidated balance sheets, for the three and nine months ended September 30, 2020 (in thousands): Amount Balance at January 1, 2020 $ 230 Revenue recognized included in beginning balance ( 230 ) Net additions 225 Balance at March 31, 2020 225 Revenue recognized included in beginning balance ( 225 ) Net additions 251 Balance at June 30, 2020 251 Revenue recognized included in beginning balance ( 251 ) Net additions 166 Balance at September 30, 2020 $ 166 The partnership expects to recognize all of the unearned revenue associated with service agreements from contracts with customers as of September 30, 2020, in the subsequent quarter when the product is withdrawn from tank storage.

Goodwill

Goodwill	9 Months Ended

Goodwill [Abstract]
Goodwill	3 . GOODWILL The partnership currently has one reporting unit, BlendStar, to which goodwill is assigned. During the first half of 2020, a decline in the partnership’s stock price resulted in a decrease in the partnership’s market capitalization. As such, the partnership determined a triggering event had occurred that required an interim impairment assessment for its Blendstar reporting unit for both the three months ended March 31, 2020 as well as the three months ended June 30, 2020. Significant assumptions inherent in the valuation methodologies for goodwill impairment testing were employed and include, but are not limited to, market capitalization, prospective financial information, growth rates, discount rates, inflationary factors, and cost of capital. Based on the partnership’s quantitative evaluation, it was determined that the fair value of the Blendstar reporting unit exceeded its carrying value, and the partnership concluded that the goodwill assigned to the Blendstar reporting unit was not impaired, but could be at risk of future impairment. During the three months ended September 30, 2020, the partnership did not identify any triggering events, and as such, no impairment assessment was deemed necessary.

Debt

Debt	9 Months Ended
	Sep. 30, 2020
Debt [Abstract]
Debt	4. DEBT Credit Facility Green Plains Operating Company has a credit facility to fund working capital, capital expenditures and other general partnership purposes. The credit facility was amended on June 4, 2020, decreasing the total amount available from $ 200.0 million to $ 135.0 million. The amended credit facility includes a $ 130.0 million term loan and a $ 5.0 million revolving credit facility maturing on December 31, 2021 . The partnership made $ 12.5 million in principal payments on the term loan during the three and nine months ended September 30, 2020. Monthly principal payments of $ 2.5 million are required October 15, 2020 through April 15, 2021, with a step up to monthly payments of $ 3.2 million beginning May 15, 2021 through maturity. In certain situations the partnership is required to make prepayments on the outstanding principal balance on the credit facility. If at any time subsequent to July 15, 2020, the partnership’s cash balance exceeds $ 2.5 million for more than five consecutive business days, prepayments of outstanding principal are required in an amount equal to the excess cash. The partnership is also required to prepay outstanding principal on the credit facility with 100 % of net cash proceeds from any asset disposition or recovery event. Any prepayments on the term loan are applied to the remaining principal balance in inverse order of maturity, including the final payment. As of September 30, 2020, no prepayments on the term loan were required or paid. The term loan balance, and any advances on the revolver, are subject to a floating interest rate based on a 1.00 % Libor floor plus 4.50 % to 5.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. The unused portion of the revolver is subject to a commitment fee of 0.50 %. The credit facility also allows for swing line loans subject to the revolver availability. Swing line loans are subject to a floating interest rate based on the Prime Rate plus 3.50 % to 4.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. As of September 30, 2020, the term loan had a balance of $ 117.5 million and an interest rate of 6.00 %, and there was a swing line loan outstanding of $ 0.7 million at an interest rate of 7.25 %. The partnership’s obligations under the credit facility are secured by a first priority lien on (i) the equity interests of the partnership’s present and future subsidiaries, (ii) all of the partnership’s present and future personal property, such as investment property, general intangibles and contract rights, including rights under any agreements with Green Plains Trade, (iii) all proceeds and products of the equity interests of the partnership’s present and future subsidiaries and its personal property and (iv) substantially all of the partnership’s real property and material leases of real property. The terms impose affirmative and negative covenants, including restrictions on the partnership’s ability to incur additional debt, acquire and sell assets, create liens, invest capital, pay distributions and materially amend the partnership’s commercial agreements with Green Plains Trade. The credit facility also requires the partnership to maintain a maximum consolidated leverage ratio, as of the end of any fiscal quarter, of no more than 3.00 x that decreases 0.25 x each quarter to 1.50 x by December 31, 2021, and a minimum consolidated debt service coverage ratio of 1.10 x , each of which is calculated on a pro forma basis with respect to acquisitions and divestitures occurring during the applicable period. The consolidated leverage ratio is calculated by dividing total funded indebtedness by the sum of the four preceding fiscal quarters’ consolidated EBITDA. The consolidated debt service coverage ratio is calculated by taking the sum of the four preceding fiscal quarters’ consolidated EBITDA minus income taxes and consolidated capital expenditures for such period divided by the sum of the four preceding fiscal quarters’ consolidated interest charges plus consolidated scheduled funded debt payments for such period. Under the amended terms of the credit facility, the partnership may make quarterly distribution payments in an aggregate amount not to exceed $ 0.12 per outstanding unit, so long as (i) no default has occurred and is continuing, or would result from payment of the distribution, and (ii) the partnership and its subsidiaries are in compliance with its financial covenants and remain in compliance after payment of the distribution. The partnership had $ 118.2 million and $ 132.1 million of borrowings outstanding under the credit facility as of September 30, 2020, and December 31, 2019, respectively. In addition, the partnership had $ 2.8 million of debt issuance costs recorded as a direct reduction of the carrying value of the partnership’s long-term debt as of September 30, 2020. The partnership believes the carrying amount of its debt approximated fair value at both September 30, 2020 and December 31, 2019. Covenant Compliance The partnership, including all of its subsidiaries, was in compliance with its debt covenants as of September 30, 2020.

Asset Retirement Obligations [Abstract]
Asset Retirement Obligations	5. ASSET RETIREMENT OBLIGATIONS Under various lease agreements, the partnership has AROs when certain machinery and equipment are disposed or operating leases expire. During the nine months ended September 30, 2020, the partnership reassessed the estimated cost of AROs related to its railcar operating leases. The reassessment resulted in a change in estimated costs that has been reflected as an increase of $ 0.3 million to the ARO liabilities and corresponding assets on the consolidated balance sheet as of September 30, 2020. The following table summarizes the change in the liability for the AROs during the three and nine months ended September 30, 2020 (in thousands): Amount Balance at January 1, 2020 $ 3,065 Additional asset retirement obligations incurred 67 Liabilities settled ( 44 ) Accretion expense 62 Change in estimate 323 Balance at March 31, 2020 3,473 Additional asset retirement obligations incurred 81 Liabilities settled ( 9 ) Accretion expense 65 Balance at June 30, 2020 3,610 Additional asset retirement obligations incurred 110 Liabilities settled ( 86 ) Accretion expense 68 Balance at September 30, 2020 $ 3,702

Unit-Based Compensation [Abstract]
Unit-Based Compensation	6. UNIT-BASED COMPENSATION The partnership has a long-term incentive plan (LTIP) intended to promote the interests of the partnership, its general partner and affiliates by providing unit-based incentive compensation awards to employees, consultants and directors to encourage superior performance. The LTIP reserves 2,500,000 common limited partner units for issuance in the form of options, restricted units, phantom units, distribution equivalent rights, substitute awards, unit appreciation rights, unit awards, profit interest units or other unit-based awards.

Earnings Per Unit [Abstract]
Earnings Per Unit	8. EARNINGS PER UNIT The partnership computes earnings per unit using the two-class method. Earnings per unit applicable to common units is calculated by dividing the respective limited partners’ interest in net income by the weighted average number of common units outstanding during the period, adjusted for the dilutive effect of any outstanding dilutive securities. Diluted earnings per limited partner unit was the same as basic earnings per limited partner unit as there were no potentially dilutive common units outstanding as of September 30, 2020. The following tables show the calculation of earnings per limited partner unit – basic and diluted (in thousands, except for per unit data): Three Months Ended September 30, 2020 Limited Partner Common Units General Partner Total Net income: Distributions declared $ 2,791 $ 57 $ 2,848 Earnings in excess of distributions 7,309 149 7,458 Total net income $ 10,100 $ 206 $ 10,306 Weighted-average units outstanding - basic and diluted 23,161 Earnings per limited partner unit - basic and diluted $ 0.44 Nine Months Ended September 30, 2020 Limited Partner Common Units General Partner Total Net income: Distributions declared $ 8,349 $ 171 $ 8,520 Earnings in excess of distributions 21,893 446 22,339 Total net income $ 30,242 $ 617 $ 30,859 Weighted-average units outstanding - basic and diluted 23,145 Earnings per limited partner unit - basic and diluted $ 1.31 Three Months Ended September 30, 2019 Limited Partner Common Units General Partner Total Net income: Distributions declared $ 11,001 $ 279 $ 11,280 Earnings less than distributions ( 1,072 ) ( 76 ) ( 1,148 ) Total net income $ 9,929 $ 203 $ 10,132 Weighted-average units outstanding - basic and diluted 23,138 Earnings per limited partner unit - basic and diluted $ 0.43 Nine Months Ended September 30, 2019 Limited Partner Common Units General Partner Total Net income: Distributions declared $ 32,993 $ 836 $ 33,829 Earnings less than distributions ( 2,525 ) ( 215 ) ( 2,740 ) Total net income $ 30,468 $ 621 $ 31,089 Weighted-average units outstanding - basic and diluted 23,125 Earnings per limited partner unit - basic and diluted $ 1.32

Income Taxes [Abstract]
Income Taxes	9. INCOME TAXES The partnership is a limited partnership, which is not subject to federal income taxes. The general partner and the unitholders are responsible for paying federal and state income taxes on their share of the partnership’s taxable income. However, the partnership owns a subsidiary that is taxed as a corporation for federal and state income tax purposes. In addition, the partnership is subject to state income taxes in certain states. As a result, the financial statements reflect a provision or benefit for such income taxes. The partnership recognizes uncertainties in income taxes based upon the technical merits of the position, and measures the maximum benefit and degree of likelihood to determine the tax liability in the financial statements.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	10. COMMITMENTS AND CONTINGENCIES Operating Lease Expense The partnership leases certain facilities, parcels of land, and railcars with remaining terms ranging from less than one year to approximately 11.1 years, including renewal options reasonably certain to be exercised for the land and facility leases. Railcar agreement renewals are not considered reasonably certain to be exercised as they are typically subject to significant market dynamics which impact the underlying terms of the agreements. The partnership may sublease certain of its railcars to third parties on a short-term basis. These subleases are classified as operating leases, with the associated sublease revenue recognized on a straight-line basis over the lease term. The components of lease expense for the three and nine months ended September 30, 2020 and 2019, are as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Lease expense Operating lease expense (1) $ 4,277 $ 3,618 $ 11,970 $ 11,903 Variable lease benefit (2) ( 196 ) ( 90 ) ( 221 ) ( 239 ) Total lease expense $ 4,081 $ 3,528 $ 11,749 $ 11,664 (1) Amount includes an additional $ 0.2 million of accelerated lease expense due to the early termination of leased railcar assets for the three and nine months ended September 30, 2020. (2) Represents railcar lease abatements provided by the lessor when railcars are out of service during periods of maintenance or upgrade, offset by amounts incurred in excess of the minimum payments required for the handling and unloading of railcars for a certain lease. Supplemental cash flow information related to operating leases for the three and nine months ended September 30, 2020 and 2019, are as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,918 $ 3,502 $ 11,279 $ 11,988 Right-of-use assets obtained in exchange for lease obligations: Operating leases 6,310 4,427 11,504 10,634 Right-of-use assets and lease obligations derecognized due to lease modifications: Operating leases 7 1,405 7 1,405 Supplemental balance sheet information related to operating leases is as follows: September 30, 2020 December 31, 2019 Weighted average remaining lease term 4.4 years 4.2 years Weighted average discount rate 4.79 % 5.19 % Aggregate minimum lease payments under the operating lease agreements for the remainder of 2020 and in future years are as follows (in thousands): Year Ending December 31, Amount 2020 $ 4,272 2021 11,297 2022 9,763 2023 6,593 2024 4,768 Thereafter 5,277 Total $ 41,970 Less: Present value discount ( 4,226 ) Operating lease liabilities $ 37,744 The partnership has additional railcar operating leases that will commence in the fourth quarter of 2020 and the first half of 2021 to replace expiring leases, with undiscounted future lease payments of approximately $ 24.5 million and lease terms of five to six years . These amounts are not included in the tables above. Lease Revenue The components of lease revenue are as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Lease revenue Operating lease revenue $ 17,613 $ 16,981 $ 51,744 $ 51,751 Variable lease revenue (1) 544 ( 259 ) 571 ( 457 ) Sublease revenue 16 111 152 539 Total lease revenue $ 18,173 $ 16,833 $ 52,467 $ 51,833 (1) Represents amounts charged to Green Plains Trade under the storage and throughput agreement in excess of the initial rate of $ 0.05 per gallon, amounts delivered by Green Plains Trade and other customers in excess of various minimum volume commitments, and the difference between the contracted railcar volumetric capacity and the actual amount provided to Green Plains Trade during the period. In accordance with the amended storage and throughput agreement, Green Plains Trade is obligated to deliver a minimum volume of 235.7 mmg per calendar quarter to the partnership’s storage facilities and pay $ 0.05 per gallon on all volume it throughputs associated with the agreement through June 30, 2020, and $ 0.05312 per gallon subsequent to June 30, 2020. The remaining lease term for this agreement is 7.8 years, with automatic one year renewal periods, for which either party has the right to terminate the contract. Due to the unilateral right to termination during the renewal period, the lease contract would no longer contain enforceable rights or obligations. Therefore, the lease term does not include the successive one year renewal periods. Anticipated minimum operating lease revenue under this agreement assuming a consistent rate of $ 0.05312 per gallon for the remainder of 2020 and in future years is as follows (in thousands): Year Ending December 31, Amount 2020 $ 12,520 2021 50,082 2022 50,082 2023 50,082 2024 50,082 Thereafter 175,284 Total $ 388,132 In accordance with the amended rail transportation services agreement with Green Plains Trade, Green Plains Trade is required to pay the rail transportation services fee for railcar volumetric capacity provided by the partnership. The remaining lease term for this agreement is 4.8 years, with automatic one year renewal periods, for which either party has the right to terminate the contract. Due to the unilateral right to termination during the renewal period, the lease contract would no longer contain enforceable rights or obligations. Therefore, the lease term does not include the successive one year renewal periods. Under the terms of the agreement, Green Plains Trade is not required to pay for volumetric capacity that is not available due to inspections, upgrades, or routine repairs and maintenance. As a result, the actual volumetric capacity billed may be reduced based on the amount of volumetric capacity available for use during any applicable period. Anticipated minimum operating lease revenue under this agreement for the remainder of 2020 and in future years is as follows (in thousands): Year Ending December 31, Amount 2020 $ 6,058 2021 18,054 2022 15,858 2023 10,126 2024 7,589 Thereafter 4,199 Total $ 61,884 The partnership provides terminal services and logistics solutions to certain customers under various terminal service agreements, some of which have minimum volume commitments. At terminals where a customer is predominantly provided exclusive use of the terminal or tank storage assets, the partnership is considered a lessor as part of an operating lease agreement. Revenue is recognized over the term of the lease based on the minimum volume commitment, or total actual throughput if in excess of the minimum volume commitment. The partnership currently has one such agreement, with a remaining lease term of 4 .9 years , which includes renewal options reasonably certain to be exercised. Minimum operating lease revenue for this terminal for the remainder of 2020 and in future years is as follows (in thousands): Year Ending December 31, Amount 2020 $ 18 2021 74 2022 74 2023 74 2024 74 Thereafter 49 Total $ 363 Other Commitments and Contingencies The partnership has agreements for contracted services with certain vendors that require the partnership to pay minimum monthly amounts, which expire on various dates. These agreements do not contain an identified asset and therefore are not considered operating leases. The partnership satisfied the minimum commitments under these agreements during the three and nine months ended September 30, 2020 and 2019. Aggregate minimum payments under these agreements for the remainder of 2020 and in future years are as follows (in thousands): Year Ending December 31, Amount 2020 $ 168 2021 141 2022 157 2023 - 2024 - Thereafter - Total $ 466 Legal The partnership may be involved in litigation that arises during the ordinary course of business.

Related Party Transactions [Abstract]
Related Party Transactions	11. RELATED PARTY TRANSACTIONS The partnership engages in various related party transactions with Green Plains and subsidiaries of Green Plains. Green Plains provides a variety of shared services to the partnership, including general management, accounting and finance, payroll and human resources, information technology, legal, communications and treasury activities. These costs are proportionally allocated by Green Plains to its subsidiaries based on common financial metrics management believes are reasonable. The partnership recorded expenses related to these shared services of $ 0.8 million and $ 2.5 million for the three and nine months ended September 30, 2020, respectively, and $ 0.8 million and $ 2.6 million for the three and nine months ended September 30, 2019, respectively. In addition, the partnership reimburses Green Plains for wages and benefit costs of employees directly performing services on its behalf. Green Plains may also pay certain direct costs on behalf of the partnership, which are reimbursed by the partnership. The partnership believes the consolidated financial statements reflect all material costs of doing business related to its operations, including expenses incurred by other entities on its behalf. Omnibus Agreement The partnership has entered into an omnibus agreement, as amended, with Green Plains and its affiliates which, among other terms and conditions, addresses the partnership’s obligation to reimburse Green Plains for direct or allocated costs and expenses incurred by Green Plains for general and administrative services; the prohibition of Green Plains and its subsidiaries from owning, operating or investing in any business that owns or operates fuel terminals or fuel transportation assets; the partnership’s right of first offer to acquire assets if Green Plains decides to sell them; a nontransferable, nonexclusive, royalty-free license to use the Green Plains trademark and name; the allocation of taxes among the parent, the partnership and its affiliates and the parent’s preparation and filing of tax returns; and an indemnity by Green Plains for certain environmental and other liabilities. If Green Plains or its affiliates cease to control the general partner, then either Green Plains or the partnership may terminate the omnibus agreement, provided that (i) the indemnification obligations of the parties survive according to their respective terms; and (ii) Green Plains’ obligation to reimburse the partnership for operational failures survives according to its terms. Operating Services and Secondment Agreement The general partner has entered into an operational services and secondment agreement, as amended, with Green Plains. Under the terms of the agreement, Green Plains seconds employees to the general partner to provide management, maintenance and operational functions for the partnership, including regulatory matters, health, environment, safety and security programs, operational services, emergency response, employee training, finance and administration, human resources, business operations and planning. The seconded personnel are under the direct management and supervision of the general partner who reimburses the parent for the cost of the seconded employees, including wages and benefits. If a seconded employee does not devote 100% of his or her time providing services to the general partner, the general partner reimburses the parent for a prorated portion of the employee’s overall wages and benefits based on the percentage of time the employee spent working for the general partner. Under the operational services and secondment agreement, Green Plains will indemnify the partnership from any claims, losses or liabilities incurred by the partnership, including third-party claims, arising from their performance of the operational services secondment agreement; provided, however, that Green Plains will not be obligated to indemnify the partnership for any claims, losses or liabilities arising out of the partnership’s gross negligence, willful misconduct or bad faith with respect to any services provided under the operational services and secondment agreement. Commercial Agreements The partnership has various fee-based commercial agreements with Green Plains Trade, including:  Storage and throughput agreement, expiring on June 30, 2028;  Rail transportation services agreement, expiring on June 30, 2025;  Trucking transportation agreement, expiring on May 31, 2021;  Terminal services agreement for the Birmingham, Alabama unit train terminal, expiring on December 31, 2022; and  Various other terminal services agreements for other fuel terminal facilities, each with Green Plains Trade. The storage and throughput, rail transportation services, and trucking transportation agreements have various automatic renewal terms if not cancelled by either party within specified timeframes. Please refer to Item 15 – Exhibits, Financial Statement Schedule in our 2019 annual report for further details. The storage and throughput agreement and terminal services agreements are supported by minimum volume commitments. The rail transportation services agreement is supported by minimum take-or-pay volumetric capacity commitments. Under the storage and throughput agreement, as amended, Green Plains Trade is obligated to deliver a minimum volume of 235.7 mmg of product per calendar quarter to the partnership’s storage facilities and pay $ 0.05 per gallon on all volume it throughputs through June 30, 2020, and $ 0.05312 per gallon subsequent to June 30, 2020. If Green Plains Trade fails to meet its minimum volume commitment during any quarter, Green Plains Trade will pay the partnership a deficiency payment equal to the deficient volume multiplied by the applicable fee. The deficiency payment may be applied as a credit toward payments due on future volumes delivered by Green Plains Trade in excess of the minimum volume commitment during the following four quarters, after which time this option will expire. For the three months ended September 30, 2020, the partnership charged Green Plains Trade $ 2.4 million related to the minimum volume commitment deficiency for the quarter, resulting in a credit to be applied against excess volumes in future periods. The cumulative minimum volume deficiency credits available to Green Plains Trade as of September 30, 2020 totaled $ 6.7 million. If these credits are unused by Green Plains Trade, $ 4.3 million will expire on June 30, 2021 and $ 2.4 million will expire on September 30, 2021. These credits have been recognized in revenue by the partnership, and as such, future volumes throughput by Green Plains Trade in excess of the quarterly minimum volume commitment, up to the amount of these credits, will not be recognized in revenue in future periods prior to expiration. Under the rail transportation services agreement, Green Plains Trade is obligated to use the partnership to transport ethanol and other fuels from receipt points identified by Green Plains Trade to nominated delivery points. During the three and nine months ended September 30, 2020, the average daily railcar volumetric capacity provided by the partnership was 81.5 mmg and 80.4 mmg, respectively, and the associated monthly fee was approximately $ 0.0226 and $ 0.0220 per gallon, res pec tively. During the three and nine months ended September 30, 2019, the average daily railcar volumetric capacity provided by the partnership was 77.0 mmg and 80.5 mmg, respectively, and the associated monthly fee was approximately $ 0.0212 and $ 0.0215 per gallon, res pec tively. The partnership’s leased railcar fleet consisted of approximately 2,820 and 2,690 railcars as of September 30, 2020 and 2019, respectively. Green Plains Trade is also obligated to use the partnership for logistical operations management and other services related to average daily railcar volumetric capacity provided by Green Plains Trade, which was approximately 0.7 mmg and 2.0 mmg for the three and nine months ended September 30, 2020, respectively. Green Plains Trade is obligated to pay a monthly fee of approximately $ 0.0013 per gallon for these services. In addition, Green Plains Trade reimburses the partnership for costs related to: (1) railcar switching and unloading fees; (2) increased costs related to changes in law or governmental regulation related to the specification, operation or maintenance of railcars; (3) demurrage charges, except when the charges are due to the partnership’s gross negligence or willful misconduct; and (4) fees related to rail transportation services under transportation contracts with third-party common carriers. As needed, Green Plains Trade contracts with the partnership for additional railcar volumetric capacity during the normal course of business at comparable margins. Under the trucking transportation agreement, Green Plains Trade pays the partnership to transport ethanol and other fuels by truck from identified receipt points to various delivery points. Green Plains Trade is obligated to pay a monthly trucking transportation services fee equal to the aggregate volume transported in a calendar month by the partnership’s trucks, multiplied by the applicable rate for each truck lane. A truck lane is defined as a specific and routine route of travel between a point of origin and point of destination. Rates for each truck lane are negotiated based on product, location, mileage and other factors. Green Plains Trade reimburses the partnership for costs related to: (1) truck switching and unloading fees; (2) increased costs related to changes in law or governmental regulation related to the specification, operation and maintenance of trucks; and (3) fees related to trucking transportation services under transportation contracts with third-party common carriers. Under the existing Birmingham terminal services agreement, effective through December 31, 2022, Green Plains Trade is obligated to throughput a minimum volume commitment of approximately 8.3 mmg per month and pay associated throughput fees, as well as fees for ancillary services. The partnership recorded revenues from Green Plains Trade under the storage and throughput agreement and rail transportation services agreement of $ 18.1 million and $ 52.0 million for the three and nine months ended September 30, 2020 and $ 16.6 million and $ 50.9 million for the three and nine months ended September 30, 2019, respectively. The partnership recorded revenues from Green Plains Trade and other Green Plains subsidiaries related to trucking and terminal services of $ 2.2 million and $ 6.3 million for the three and nine months ended September 30, 2020 and $ 2.2 million and $ 5.8 million for the nine months ended September 30, 2019, respectively. Cash Distributions The partnership distributed $ 1.5 million and $ 8.7 million to Green Plains related to the quarterly cash distribution paid for the three and nine months ended September 30, 2020, respectively, and $ 5.7 million and $ 17.3 million for the three and nine months ended September 30, 2019, respectively.

Consolidated Financial Statements	Consolidated Financial Statements The consolidated financial statements include the accounts of the partnership and its controlled subsidiaries. All significant intercompany balances and transactions are eliminated on a consolidated basis for reporting purposes. Results for the interim periods presented are not necessarily indicative of the expected results for the entire year. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and footnotes required by GAAP, the consolidated financial statements should be read in conjunction with the partnership’s 2019 annual report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on February 20, 2020. The partnership accounts for its interest in joint ventures using the equity method of accounting, with its investment recorded at the acquisition cost plus the partnership’s share of equity in undistributed earnings and reduced by the partnership’s share of equity in undistributed losses and distributions received.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements Preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and revenues and expenses during the reporting period. The partnership bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances. The partnership regularly evaluates the appropriateness of these estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including, but not limited to, those related to revenue recognition, depreciation of property and equipment, asset retirement obligations, operating leases, and impairment of long-lived assets and goodwill, are impacted significantly by judgments, assumptions and estimates used to prepare the consolidated financial statements.
Description of Business	Description of Business The partnership provides fuel storage and transportation services by owning, operating, developing and acquiring ethanol and fuel storage terminals, transportation assets and other related assets and businesses. The partnership is its parent’s primary downstream logistics provider to support the parent’s approximately 1.1 bgy ethanol marketing and distribution business since the partnership’s assets are the principal method of storing and delivering the ethanol its parent produces. The ethanol produced by the parent is predominantly fuel grade, made principally from starch extracted from corn, and is primarily used for blending with gasoline. Ethanol currently comprises approximately 10 % of the U.S. gasoline market and is an economical source of octane and oxygenates for blending into the fuel supply. The partnership does not take ownership of, or receive any payments based on the value of the ethanol, other fuels or products it handles. As a result, the partnership does not have any direct exposure to fluctuations in commodity prices.
Revenue Recognition	Revenue Recognition The partnership recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the completion of services or the transfer of control of products to the customer or another specified third party. Operating lease revenue related to minimum volume commitments is recognized on a straight-line basis over the term of the lease. Under the terms of the storage and throughput agreement with Green Plains Trade, to the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred. The partnership generates a substantial portion of its revenues under fee-based commercial agreements with Green Plains Trade. Please refer to Note 2 - Revenue to the consolidated financial statements for further details.
Operations and Maintenance Expenses	Operations and Maintenance Expenses The partnership’s operations and maintenance expenses consist primarily of lease expenses related to the transportation assets, labor expenses, outside contractor expenses, insurance premiums, repairs and maintenance expenses, and utility costs. These expenses also include fees for certain management, maintenance and operational services to support the storage and terminal facilities, trucks, and leased railcar fleet allocated by Green Plains under the operational services and secondment agreement.
Concentrations of Credit Risk	Concentrations of Credit Risk In the normal course of business, the partnership is exposed to credit risk resulting from the possibility a loss may occur due to failure of another party to perform according to the terms of their contract. The partnership provides fuel storage and transportation services for various parties with a significant portion of its revenues earned from Green Plains Trade. The partnership continually monitors its credit risk exposure and concentrations. Please refer to Note 2 – Revenue and Note 11 – Related Party Transactions to the consolidated financial statements for additional information .
Segment Reporting	Segment Reporting The partnership accounts for segment reporting in accordance with ASC 280, Segment Reporting , which establishes standards for entities reporting information about the operating segments and geographic areas in which they operate. Management evaluated how its chief operating decision maker has organized the partnership for purposes of making operating decisions and assessing performance, and concluded it has one reportable segment.
Asset Retirement Obligations	Asset Retirement Obligations The partnership records an ARO for the fair value of the estimated costs to retire a tangible long-lived asset in the period incurred if it can be reasonably estimated, which is subsequently adjusted for accretion expense. Corresponding asset retirement costs are capitalized as a long-lived asset and depreciated on a straight-line basis over the asset’s remaining useful life. The expected present value technique used to calculate the fair value of the AROs includes assumptions about costs, settlement dates, interest accretion, and inflation. Changes in assumptions, such as the amount or timing of estimated cash flows, could increase or decrease the AROs. The partnership’s AROs are based on legal obligations to perform remedial activity related to land, machinery and equipment when certain operating leases expire. Please refer to Note 5 – Asset Retirement Obligations to the consolidated financial statements for additional information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the FASB issued amended guidance in ASC 848, Reference Rate Reform Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The expedients and exceptions provided by the amended guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The guidance is effective upon issuance and to be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The amended guidance is not expected to have a material impact on the partnership’s consolidated financial statements.
