Accounting Policies [Abstract]
Description of Business and Presentation of Financial Statements	Description of Business and Presentation of Financial Statements Holly Energy Partners, L.P. (“HEP”), together with its consolidated subsidiaries, is a publicly held master limited partnership which is 39% owned (including the 2% general partner interest) by HollyFrontier Corporation (“HFC”) and its subsidiaries. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates. We operate in one reportable segment which represents the aggregation of our petroleum product and crude pipelines business and terminals, tankage, loading rack facilities and refinery processing units. We own and operate petroleum product and crude oil pipelines, terminals, tankage and loading rack facilities and refinery processing units that support HFC’s refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States and Alon USA, Inc.’s (“Alon”) refinery in Big Spring, Texas. Additionally, we own a 75% interest in UNEV Pipeline, LLC, a 50% interest in Frontier Pipeline Company, a 50% interest in Osage Pipe Line Company, LLC (“Osage”), and a 25% interest in SLC Pipeline LLC. We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices. The consolidated financial statements included herein have been prepared without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). The interim financial statements reflect all adjustments, which, in the opinion of management, are necessary for a fair presentation of our results for the interim periods. Such adjustments are considered to be of a normal recurring nature. Although certain notes and other information required by U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted, we believe that the disclosures in these consolidated financial statements are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2015 . Results of operations for interim periods are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2016 . Acquisitions Tulsa Tanks On March 31, 2016, we acquired crude oil tanks located at HFC’s Tulsa refinery from an affiliate of Plains All American Pipeline, L.P. (“Plains”) for $39.5 million . Previously in 2009, HFC sold these tanks to Plains and leased them back, and due to HFC’s continuing interest in the tanks, HFC accounted for the transaction as a financing arrangement. Accordingly, the tanks remained on HFC’s balance sheet and were depreciated for accounting purposes. As we are a consolidated variable interest entity of HFC, this transaction was recorded as a transfer between entities under common control and reflects HFC’s carrying basis in the net assets acquired. We have retrospectively adjusted our financial position and operating results as if these crude oil tanks were owned for all periods while we were under common control of HFC. The 2015 consolidated income statement was adjusted to reflect a $0.2 million increase in operating costs and expenses for the three months ended March 31, 2015, the consolidated balance sheet was adjusted to reflect increases of $9.3 million in net properties and equipment, $0.1 million in other long-term liabilities and $9.2 million in general partner interest at March 31, 2015. The consolidated statement of cash flows for the three months ended March 31, 2015, reflects these changes in cash flows from investing and financing activities. In connection with this transaction, we expect to enter into a 10-year throughput agreement containing minimum quarterly throughput commitments from HFC that are expected to provide minimum annualized revenues of $6.1 million . Osage On February 22, 2016, HFC obtained a 50% membership interest in Osage in a non-monetary exchange for a 20-year terminalling services agreement, whereby a subsidiary of Magellan Midstream Partners (“Magellan”) will provide terminalling services for all HFC products originating in Artesia, New Mexico requiring terminalling in or through El Paso, Texas. Osage is the owner of the Osage Pipeline, a 135-mile pipeline that transports crude oil from Cushing, Oklahoma to HFC’s El Dorado Refinery in Kansas and also connects to the Jayhawk pipeline serving the CHS Inc. refinery in McPherson, Kansas. The Osage Pipeline is the primary pipeline supplying HFC’s El Dorado refinery with crude oil. Concurrent with this transaction, we entered into a non-monetary exchange with HFC, whereby we received HFC’s interest in Osage in exchange for our El Paso terminal. Under this exchange, we agreed to build two connections on our south products pipeline system that will permit HFC access to Magellan’s El Paso terminal. Effective upon the closing of this exchange, we are the named operator of the Osage Pipeline and are working to transition into that role. Since we are a consolidated variable interest entity of HFC, this transaction was recorded as a transfer between entities under common control and reflects HFC’s carrying basis of its 50% membership interest in Osage of $44.0 million offset by our net carrying basis in the El Paso terminal of $12.0 million with the difference treated as a contribution from HFC. The carrying value of our 50% membership interest in Osage of $44.0 million exceeds the amount of the underlying equity in net assets recorded by Osage by $33.0 million . El Dorado Operating On November 1, 2015 , we acquired from HollyFrontier El Dorado Refining LLC, a wholly owned subsidiary of HFC, all the outstanding membership interests in El Dorado Operating LLC (“El Dorado Operating”), which owns the newly constructed naphtha fractionation and hydrogen generation units at HFC’s El Dorado refinery, for cash consideration of $62.0 million . In connection with this transaction, we entered into 15-year tolling agreements containing minimum quarterly throughput commitments from HFC that provide minimum annualized revenues of $15.3 million . As we are a consolidated variable interest entity of HFC, this transaction was recorded as a transfer between entities under common control and reflects HFC’s carrying basis in El Dorado Operating’s assets and liabilities. We have retrospectively adjusted our financial position and operating results as if El Dorado Operating were a consolidated subsidiary for all periods while we were under common control of HFC. The consolidated statement of cash flows for the three months ending March 31, 2015, reflects a $12.6 million recast between investing activities and financing activities. New Accounting Pronouncements Revenue Recognition In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard has an effective date of January 1, 2018. We are evaluating the impact of this standard. Consolidation In February 2015, the FASB issued a standard that modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. We adopted the new standard effective January 1, 2016. This standard had no impact on the entities we consolidate. Financial Assets and Liabilities In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard will become effective beginning with our 2018 reporting year. We are evaluating the impact of this standard. Leases In February 2016, an accounting standard update was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. This standard has an effective date of January 1, 2019, and we are evaluating the impact of this standard. Earnings Per Unit In April 2015, an accounting standard update was issued requiring changes to the allocation of the earnings or losses of a transferred business for periods before the date of a dropdown of net assets accounted for as a common control transaction entirely to the general partner for purposes of calculating historical earnings per unit. We have adopted this standard as of January 1, 2016, as required. In connection with the dropdown of assets from HFC’s Tulsa refinery on March 31, 2016, we reduced net income by $0.2 million for the three months ending March 31, 2015. This reduction had no impact on the historical earnings per unit.

Financial Instruments

Fair Value Disclosures [Abstract]
Financial Instruments	Financial Instruments Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt and interest rate swaps. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments. Debt consists of outstanding principal under our revolving credit agreement (which approximates fair value as interest rates are reset frequently at current interest rates) and our fixed interest rate senior notes. Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability) including assumptions about risk. GAAP categorizes inputs used in fair value measurements into three broad levels as follows: • (Level 1) Quoted prices in active markets for identical assets or liabilities. • (Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data. • (Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs. The carrying amounts and estimated fair values of our senior notes and interest rate swaps were as follows: March 31, 2016 December 31, 2015 Financial Instrument Fair Value Input Level Carrying Value Fair Value Carrying Value Fair Value (In thousands) Assets: Interest rate swaps Level 2 $ — $ — $ 304 $ 304 Liabilities: 6.5% Senior notes Level 2 $ 296,944 $ 295,500 $ 296,752 $ 295,500 Interest rate swaps Level 2 263 263 114 114 $ 297,207 $ 295,763 $ 296,866 $ 295,614 Level 2 Financial Instruments Our senior notes and interest rate swaps are measured at fair value using Level 2 inputs. The fair value of the senior notes is based on market values provided by a third-party bank, which were derived using market quotes for similar type debt instruments. The fair value of our interest rate swaps is based on the net present value of expected future cash flows related to both variable and fixed-rate legs of the swap agreement. This measurement is computed using the forward London Interbank Offered Rate (“LIBOR”) yield curve, a market-based observable input. See Note 6 for additional information on these instruments.

Goodwill and Intangible Assets Disclosure [Abstract]
Transportation Agreements	Transportation Agreements Our transportation agreements represent a portion of the total purchase price of certain assets acquired from Alon in 2005 and from HFC in 2008 . The Alon agreement is being amortized over 30 years ending 2035 (the initial 15 -year term of the agreement plus an expected 15 -year extension period), and the HFC agreement is being amortized over 15 years ending 2023 (the term of the HFC agreement). The carrying amounts of our transportation agreements are as follows: March 31, December 31, (In thousands) Alon transportation agreement $ 59,933 $ 59,933 HFC transportation agreement 74,231 74,231 Other 50 50 134,214 134,214 Less accumulated amortization 62,147 60,409 $ 72,067 $ 73,805 We have additional transportation agreements with HFC resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HFC. These transactions occurred while we were a consolidated variable interest entity of HFC; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employees, Retirement and Incentive Plans	Employees, Retirement and Incentive Plans Direct support for our operations is provided by Holly Logistic Services, L.L.C. (“HLS”), an HFC subsidiary, which utilizes personnel employed by HFC who are dedicated to performing services for us. Their costs, including salaries, bonuses, payroll taxes, benefits and other direct costs, are charged to us monthly in accordance with an omnibus agreement that we have with HFC. These employees participate in the retirement and benefit plans of HFC. Our share of retirement and benefit plan costs was $1.6 million and $1.4 million for the three months ended March 31, 2016 and 2015 , respectively. Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets at the El Dorado, Cheyenne and Tulsa refineries, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs related to these employees. We have a Long-Term Incentive Plan for employees and non-employee directors who perform services for us. The Long-Term Incentive Plan consists of four components: restricted or phantom units, performance units, unit options and unit appreciation rights. As of March 31, 2016 , we have two types of incentive-based awards outstanding, which are described below. The compensation cost charged against income was $0.7 million and $0.8 million for the three months ended March 31, 2016 and 2015 , respectively. We currently purchase units in the open market instead of issuing new units for settlement of all unit awards under our Long-Term Incentive Plan. As of March 31, 2016 , 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 1,480,449 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the performance units already granted. Restricted and Phantom Units Under our Long-Term Incentive Plan, we grant restricted units to non-employee directors and selected employees who perform services for us, with most awards vesting over a period of one to three years. Although full ownership of the units does not transfer to the recipients until the units vest, the recipients have distribution and voting rights on these units from the date of grant. In addition, we previously granted phantom units to certain employees. All outstanding phantom units vested in 2015, and no phantom units are currently outstanding. Vested units were paid in common units. Full ownership of the units transferred to the recipients at vesting, and the recipients did not have voting or distribution rights on these units until they vested. The fair value of each restricted unit award is measured at the market price as of the date of grant and is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award. A summary of restricted unit activity and changes during the three months ended March 31, 2016 , is presented below: Restricted Units Units Weighted Average Grant-Date Fair Value Outstanding at January 1, 2016 (nonvested) 101,408 $ 33.63 Granted 10,725 24.48 Outstanding at March 31, 2016 (nonvested) 112,133 $ 32.76 As of March 31, 2016 , there was $2.2 million of total unrecognized compensation expense related to nonvested restricted unit grants, which is expected to be recognized over a weighted-average period of 1.3 years. Performance Units Under our Long-Term Incentive Plan, we grant performance units to selected executives who perform services for us. Performance units granted are payable in common units at the end of a three-year performance period based upon the growth in our distributable cash flow per common unit over the performance period. As of March 31, 2016 , estimated unit payouts for outstanding nonvested performance unit awards ranged between 100% and 150% . We granted 10,725 performance units during the three months ended March 31, 2016 . Performance units granted in 2015 and during the three months ended March 31, 2016, vest over a three-year performance period ending December 31, 2018 and are payable in HEP common units. The number of units actually earned will be based on the growth of our distributable cash flow per common unit over the performance period, and can range from 50% to 150% of the target number of performance units granted. Although common units are not transferred to the recipients until the performance units vest, the recipients have distribution rights with respect to the common units from the date of grant. A summary of performance unit activity and changes during the three months ended March 31, 2016 , is presented below: Performance Units Units Outstanding at January 1, 2016 (nonvested) 45,494 Granted 10,725 Vesting and transfer of common units to recipients (26,157 ) Outstanding at March 31, 2016 (Nonvested) 30,062 The grant-date fair value of performance units vested and transferred to recipients during the three months ended March 31, 2016 , was $1.1 million . Based on the weighted average fair value of performance units outstanding at March 31, 2016 , of $0.9 million , there was $0.7 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 2.4 years.

Debt Instruments [Abstract]
Debt	Debt Credit Agreement In March 2016, we amended our senior secured revolving credit facility (the “Credit Agreement”) expiring in November 2018, increasing the size of the Credit Agreement from $850 million to $1.2 billion . The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit. Our obligations under the Credit Agreement are collateralized by substantially all of our assets. Indebtedness under the Credit Agreement involves recourse to HEP Logistics Holdings, L.P. (“HEP Logistics”), our general partner, and is guaranteed by our material, wholly-owned subsidiaries. Any recourse to HEP Logistics would be limited to the extent of its assets, which other than its investment in us are not significant. We may prepay all loans at any time without penalty, except for payment of certain breakage and related costs. The Credit Agreement imposes certain requirements on us with which we were in compliance as of March 31, 2016 , including: a prohibition against distribution to unitholders if, before or after the distribution, a potential default or an event of default as defined in the agreement would occur; limitations on our ability to incur debt, make loans, acquire other companies, change the nature of our business, enter into a merger or consolidation, or sell assets; and covenants that require maintenance of a specified EBITDA to interest expense ratio, total debt to EBITDA ratio and senior debt to EBITDA ratio. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of the debt and exercise other rights and remedies. Senior Notes We have $300 million in aggregate principal amount outstanding of 6.5% senior notes (the “6.5% Senior Notes”) maturing March 2020. The 6.5% Senior Notes are unsecured and impose certain restrictive covenants, with which we were in compliance as of March 31, 2016 , including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the 6.5% Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights at varying premiums over face value under the 6.5% Senior Notes. Indebtedness under the 6.5% Senior Notes involves recourse to HEP Logistics, our general partner, and is guaranteed by our wholly-owned subsidiaries. However, any recourse to HEP Logistics would be limited to the extent of its assets, which, other than its investment in us, are not significant. Long-term Debt The carrying amounts of our long-term debt are as follows: March 31, December 31, (In thousands) Credit Agreement Amount outstanding $ 765,000 $ 712,000 6.5% Senior Notes Principal 300,000 300,000 Unamortized discount and debt issuance costs (3,056 ) (3,248 ) 296,944 296,752 Total long-term debt $ 1,061,944 $ 1,008,752 Interest Rate Risk Management We use interest rate swaps (derivative instruments) to manage our exposure to interest rate risk. As of March 31, 2016 , we have two interest rate swaps with identical terms that hedge our exposure to the cash flow risk caused by the effects of LIBOR changes on $150 million of Credit Agreement advances. The swaps effectively convert $150 million of our LIBOR based debt to fixed rate debt having an interest rate of 0.74% plus an applicable margin of 2.25% as of March 31, 2016 , which equaled an effective interest rate of 2.99% . Both of these swap contracts mature in July 2017. We have designated these interest rate swaps as cash flow hedges. Based on our assessment of effectiveness using the change in variable cash flows method, we have determined these interest rate swaps are effective in offsetting the variability in interest payments on $150 million of our variable rate debt resulting from changes in LIBOR. Under hedge accounting, we adjust our cash flow hedges on a quarterly basis to their fair values with the offsetting fair value adjustments to accumulated other comprehensive income (loss). Also on a quarterly basis, we measure hedge effectiveness by comparing the present value of the cumulative change in the expected future interest to be paid or received on the variable leg of our swaps against the expected future interest payments on $150 million of our variable rate debt. Any ineffectiveness is recorded directly to interest expense. As of March 31, 2016 , we had no ineffectiveness on our cash flow hedges. At March 31, 2016 , we have accumulated other comprehensive loss of $0.3 million that relates to our current cash flow hedging instruments. Approximately $0.2 million will be transferred from accumulated other comprehensive loss into interest expense as interest is paid on the underlying swap agreement over the next twelve-month period, assuming interest rates remain unchanged.

The total cost of assets under capital leases was $3.3 million and $3.0 million as of March 31, 2016 and December 31, 2015 , respectively, with accumulated depreciation of $1.3 million and $1.1 million as of March 31, 2016 and December 31, 2015 , respectively. We include depreciation of capital leases in depreciation and amortization in our consolidated statements of income.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions We serve HFC’s refineries under long-term pipeline, terminal and tankage throughput agreements, and refinery processing unit tolling agreements expiring from 2019 to 2030. Under these agreements, HFC agrees to transport, store and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index. As of March 31, 2016 , these agreements with HFC require minimum annualized payments to us of $263.7 million . If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of these agreements, a shortfall payment may be applied as a credit in the following four quarters after its minimum obligations are met. Under certain provisions of an omnibus agreement we have with HFC (the “Omnibus Agreement”), we pay HFC an annual administrative fee (currently $2.5 million ) for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are charged to us separately by HFC. Also, we reimburse HFC and its affiliates for direct expenses they incur on our behalf. Related party transactions with HFC are as follows: • Revenues received from HFC were $82.8 million and $72.3 million for the three months ended March 31, 2016 and 2015 , respectively. • HFC charged us general and administrative services under the Omnibus Agreement of $0.6 million for each of the three months ended March 31, 2016 and 2015 . • We reimbursed HFC for costs of employees supporting our operations of $9.8 million and $8.8 million for the three months ended March 31, 2016 and 2015 , respectively. • HFC reimbursed us $1.8 million and $2.6 million for the three months ended March 31, 2016 and 2015 , respectively, for certain reimbursable costs and capital projects. • We distributed $24.5 million and $21.6 million for the three months ended March 31, 2016 and 2015 , respectively, to HFC as regular distributions on its common units and general partner interest, including general partner incentive distributions. • Accounts receivable from HFC were $33.1 million and $32.5 million at March 31, 2016 , and December 31, 2015 , respectively. • Accounts payable to HFC were $6.2 million and $11.6 million at March 31, 2016 , and December 31, 2015 , respectively. • Revenues for the three months ended March 31, 2016 and 2015 , include $5.2 million and $5.6 million , respectively, of shortfall payments billed in 2015 and 2014, respectively, as HFC did not exceed its minimum volume commitment in any of the subsequent four quarters. Deferred revenue in the consolidated balance sheets at March 31, 2016 , and December 31, 2015 , includes $1.5 million and $6.4 million , respectively, relating to certain shortfall billings. It is possible that HFC may not exceed its minimum obligations to receive credit for any of the $1.5 million deferred at March 31, 2016 . • On February 22, 2016, HFC obtained a 50% membership interest in Osage in a non-monetary exchange, whereby a subsidiary of Magellan will provide terminalling services for all HFC products originating in Artesia, New Mexico that require terminalling in or through El Paso, Texas. Concurrent with this transaction, we entered into a non-monetary exchange with HFC, whereby we received HFC’s interest in Osage in exchange for our El Paso terminal. See Note 1 for a description of this transaction. • On March 31, 2016, we acquired crude oil tanks located at HFC’s Tulsa refinery from an affiliate of Plains All American Pipeline, L.P. for $39.5 million . See Note 1 for a description of this transaction.

Partners' Equity

Partners' Capital [Abstract]
Partners' Equity	Partners’ Equity As of March 31, 2016 , HFC held 22,380,030 of our common units and the 2% general partner interest, which together constituted a 39% ownership interest in us. Additionally, HFC owned all incentive distribution rights in us. Allocations of Net Income Net income attributable to HEP is allocated between limited partners and the general partner interest in accordance with the provisions of the partnership agreement. HEP net income allocated to the general partner includes incentive distributions that are declared subsequent to quarter end. After the amount of incentive distributions is allocated to the general partner, the remaining net income attributable to HEP is allocated to the partners based on their weighted-average ownership percentage during the period. The following table presents the allocation of the general partner interest in net income for the periods presented below: Three Months Ended March 31, 2016 2015 (In thousands) General partner interest in net income $ 413 $ 246 General partner incentive distribution 11,473 9,361 Total general partner interest in net income $ 11,886 $ 9,607 Cash Distributions Our general partner, HEP Logistics, is entitled to incentive distributions if the amount we distribute with respect to any quarter exceeds specified target levels. On April 22, 2016 , we announced our cash distribution for the first quarter of 2016 of $0.575 per unit. The distribution is payable on all common and general partner units and will be paid May 13, 2016 , to all unitholders of record on May 2, 2016 . The following table presents the allocation of our regular quarterly cash distributions to the general and limited partners for the periods in which they apply. Our distributions are declared subsequent to quarter end; therefore, the amounts presented do not reflect distributions paid during the periods presented below. Three Months Ended March 31, 2016 2015 (In thousands, except per unit data) General partner interest in distribution $ 948 $ 860 General partner incentive distribution 11,473 9,361 Total general partner distribution 12,421 10,221 Limited partner distribution 33,728 31,528 Total regular quarterly cash distribution $ 46,149 $ 41,749 Cash distribution per unit applicable to limited partners $ 0.5750 $ 0.5375 As a master limited partnership, we distribute our available cash, which historically has exceeded our net income attributable to HEP because depreciation and amortization expense represents a non-cash charge against income. The result is a decline in our partners’ equity since our regular quarterly distributions have exceeded our quarterly net income attributable to HEP. Additionally, if the asset contributions and acquisitions from HFC had occurred while we were not a consolidated variable interest entity of HFC, our acquisition cost in excess of HFC’s historical basis in the transferred assets would have been recorded in our financial statements at the time of acquisition as increases to our properties and equipment and intangible assets instead of decreases to our partners’ equity.

Accrual for Environmental Loss Contingencies [Abstract]
Environmental	Environmental We incurred no expenses for the three months ended March 31, 2016 and $4.2 million for the three months ended March 31, 2015 , for environmental remediation obligations. The accrued environmental liability, net of expected recoveries from indemnifying parties, reflected in our consolidated balance sheets was $7.4 million and $7.7 million at March 31, 2016 , and December 31, 2015 , respectively, of which $5.8 million and $6.1 million , respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time. Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of March 31, 2016 , and December 31, 2015 , our accrued environmental liability included $1.0 million and $6.4 million , respectively, for HFC indemnified liabilities, and other assets included equal and offsetting balances representing amounts due from HFC related to indemnifications for environmental remediation liabilities.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Revenue Recognition In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard has an effective date of January 1, 2018. We are evaluating the impact of this standard. Consolidation In February 2015, the FASB issued a standard that modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. We adopted the new standard effective January 1, 2016. This standard had no impact on the entities we consolidate. Financial Assets and Liabilities In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard will become effective beginning with our 2018 reporting year. We are evaluating the impact of this standard. Leases In February 2016, an accounting standard update was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. This standard has an effective date of January 1, 2019, and we are evaluating the impact of this standard. Earnings Per Unit In April 2015, an accounting standard update was issued requiring changes to the allocation of the earnings or losses of a transferred business for periods before the date of a dropdown of net assets accounted for as a common control transaction entirely to the general partner for purposes of calculating historical earnings per unit. We have adopted this standard as of January 1, 2016, as required. In connection with the dropdown of assets from HFC’s Tulsa refinery on March 31, 2016, we reduced net income by $0.2 million for the three months ending March 31, 2015. This reduction had no impact on the historical earnings per unit.
