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 36% owned (including the 2% general partner interest) by HollyFrontier Corporation (“HFC”) and its subsidiaries as of June 30, 2017 . 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 own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support HFC’s refining and marketing operations in the Mid-Continent, Southwest and Northwest 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 (“UNEV”), a 50% interest in Frontier Aspen LLC, a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC and a 25% interest in SLC Pipeline LLC. We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 13. 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, 2016 . 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, 2017 . Principles of Consolidation and Common Control Transactions The consolidated financial statements include our accounts, our Predecessor's (defined below) and those of subsidiaries and joint ventures that we control. All significant intercompany transactions and balances have been eliminated. Most of our acquisitions from HFC occurred while we were a consolidated variable interest entity (“VIE”) of HFC. Therefore, as an entity under common control with HFC, we recorded these acquisitions on our balance sheets at HFC's historical basis instead of our purchase price or fair value. GAAP requires transfers of a business between entities under common control to be accounted for as though the transfer occurred as of the beginning of the period of transfer, and prior period financial statements and financial information are retrospectively adjusted to include the historical results and assets of the acquisitions from HFC for all periods presented prior to the effective dates of each acquisition. We refer to the historical results of the acquisitions prior to their respective acquisition dates as those of our "Predecessor." Many of these transactions are cash purchases and do not involve the issuance of equity; however, GAAP requires the retrospective adjustment of financial statements. Therefore, in such transactions, the prior year balance sheet includes as equity the amount of cost incurred by HFC to that date. See “Acquisitions” below for further discussion as well as effects of the retrospective adjustments. Acquisitions 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 became the named operator of the Osage Pipeline and transitioned into that role on September 1, 2016. Since we are a consolidated VIE 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 $44.5 million offset by our net carrying basis in the El Paso terminal of $12.1 million with the difference recorded as a contribution from HFC. However, since these transactions were concurrent, there was no impact on periods prior to February 22, 2016. Tulsa Tanks On March 31, 2016, we acquired crude oil tanks (the “Tulsa Tanks”) located at HFC’s Tulsa refinery from an affiliate of Plains All American Pipeline, L.P. (“Plains”) for cash consideration of $39.5 million . 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 had remained on HFC’s balance sheet and were being depreciated for accounting purposes. As we are a consolidated VIE 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 units were owned for all periods while we were under common control of HFC. Cheyenne Pipeline On June 3, 2016, we acquired a 50% interest in Cheyenne Pipeline LLC, owner of the Cheyenne Pipeline, in exchange for a contribution of $42.6 million in cash to Cheyenne Pipeline LLC. Cheyenne Pipeline LLC will continue to be operated by an affiliate of Plains, which owns the remaining 50% interest. The 87 -mile crude oil pipeline runs from Fort Laramie to Cheyenne, Wyoming and has an 80,000 barrel per day (“bpd”) capacity. Woods Cross Operating Effective October 1, 2016, we acquired all the membership interests of Woods Cross Operating LLC (“Woods Cross Operating”), a wholly owned subsidiary of HFC, which owns the newly constructed atmospheric distillation tower, fluid catalytic cracking unit, and polymerization unit located at HFC’s Woods Cross Refinery, for cash consideration of $278 million . The consideration was funded with $103 million in proceeds from the private placement of 3,420,000 common units with the balance funded with borrowings under our credit facility. In connection with this transaction, we entered into 15 -year tolling agreements containing minimum quarterly throughput commitments from HFC. As of June 30, 2017, these commitments provide minimum annualized revenues of $57 million . The Utah Division of Air Quality issued an air quality permit to HollyFrontier Woods Cross Refining LLC (“HFC Woods Cross Refining”) authorizing the expansion units at the Woods Cross Refinery. The appeal proceeding challenging the Utah Department of Environmental Quality’s decision to uphold the air quality permit was taken under advisement by the Utah Supreme Court in June 2017, and the court issued a decision in favor of the state of Utah and HFC. As a result, the purchase agreement remedies we had against HFC in the event of an unfavorable ruling in the appeal proceeding are no longer applicable. As we are a consolidated VIE 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 units were owned for all periods while we were under common control of HFC. The following tables present lines in our previously reported income statement for the three and six months ended June 30, 2016 , that were impacted by Predecessor transactions, and retrospectively adjusts only the acquisition of Woods Cross Operating as the Tulsa Tanks acquisition included Predecessor transactions in the previously reported income statement for the three and six months ended June 30, 2016 . However, the presentation of the Tulsa Tanks’ Predecessor transactions have been modified as shown in the table below. Three Months Ended June 30, 2016 Holly Energy Partners, L.P.

We adopted this standard as of January 1, 2016. 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 and six months ended June 30, 2016, and in connection with the purchase of HFC’s Woods Cross refinery units on October 1, 2016, we reduced net income by $2.0 million and $2.9 million , respectively, for the three and six months ended June 30, 2016 . This reduction had no impact on the historical earnings per limited partner unit. Share-Based Compensation In March 2016, an accounting standard update was issued which simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. We adopted this standard effective January 1, 2017, with no impact to our financial condition, results of operations and cash flows. As permitted by the standard, we continue to account for forfeitures on an estimated basis. Accounting Pronouncements Not Yet Adopted 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, and we intend to account for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment is recorded to retained earnings as of the date of initial application. Our preparation for adoption of this standard is in progress, and we are currently evaluating terms, conditions and our performance obligations of our existing contracts with customers. We are evaluating the effect of this standard on our revenue recognition policies and whether it will have a material impact on our financial condition or results of operations. Business Combinations In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard has an effective date of January 1, 2018, and we are evaluating its impact. 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.

Financial Instruments	Jun. 30, 2017
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 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: June 30, 2017 December 31, 2016 Financial Instrument Fair Value Input Level Carrying Value Fair Value Carrying Value Fair Value (In thousands) Assets: Interest rate swaps Level 2 $ 63 $ 63 $ 91 $ 91 Liabilities: 6.5% Senior notes Level 2 $ — $ — $ 297,519 $ 308,250 6% Senior notes Level 2 393,739 418,000 393,393 415,500 $ 393,739 $ 418,000 $ 690,912 $ 723,750 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 are intangible assets that represent a portion of the total purchase price of certain assets acquired from Alon in 2005 and from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC. 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: June 30, 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 70,833 67,358 $ 63,381 $ 66,856 Amortization expense was $3.5 million for each of the six months ended June 30, 2017 and 2016 . 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 VIE 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 $1.3 million and $1.3 million for the three months ended June 30, 2017 and 2016 , respectively, and $3.0 million and $2.9 million for the six months ended June 30, 2017 and 2016 . 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, 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. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (a significant proportion of our awards) is to expense the costs ratably over the vesting periods. As of June 30, 2017 , we had two types of incentive-based awards outstanding, which are described below. The compensation cost charged against income was $0.6 million and $0.5 million for the three months ended June 30, 2017 and 2016 , respectively, and $0.9 million and $1.2 million for the six months ended June 30, 2017 and 2016 . 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 June 30, 2017 , 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 1,409,261 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the unvested performance units. Restricted 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. 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 six months ended June 30, 2017 , is presented below: Restricted Units Units Weighted Average Grant-Date Fair Value Outstanding at January 1, 2017 (nonvested) 123,988 $ 32.96 Granted 20,348 36.01 Forfeited (17,653 ) 29.75 Outstanding at June 30, 2017 (nonvested) 126,683 $ 33.90 As of June 30, 2017 , there was $1.6 million of total unrecognized compensation expense related to nonvested restricted unit grants, which is expected to be recognized over a weighted-average period of 1.0 year. 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 June 30, 2017 , estimated unit payouts for outstanding nonvested performance unit awards ranged between 100% and 150% of the target number of performance units granted. We did not grant any performance units during the six months ended June 30, 2017 . Performance units granted in 2016 vest over a three-year performance period ending December 31, 2019, 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 six months ended June 30, 2017 , is presented below: Performance Units Units Outstanding at January 1, 2017 (nonvested) 49,520 Vesting and transfer of common units to recipients (2,262 ) Forfeited (21,228 ) Outstanding at June 30, 2017 (nonvested) 26,030 The grant-date fair value of performance units vested and transferred to recipients during the six months ended June 30, 2017 , was $0.1 million . Based on the weighted average fair value of performance units outstanding at June 30, 2017 , of $0.9 million , there was $0.5 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 1.8 years.

Debt

Debt Instruments [Abstract]
Debt	Debt Credit Agreement At June 30, 2017, we had a $1.2 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in November 2018 . On July 27, 2017, the Credit Agreement was amended, increasing the size of the facility from $1.2 billion to $1.4 billion and extending the expiration to July 2022. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit, and it contains an accordion feature giving us the ability to increase the size of the facility by up to $300 million with additional lender commitments. Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material, wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance with certain financial covenants consisting of total leverage, senior secured leverage, and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated. We may prepay all loans outstanding at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercise other rights and remedies. We were in compliance with the covenants as of June 30, 2017 . Senior Notes On January 4, 2017, we redeemed the $300 million aggregate principal amount of 6.5% senior notes (the “6.5% Senior Notes”) at a redemption cost of $309.8 million at which time we recognized a $12.2 million early extinguishment loss consisting of a $9.8 million debt redemption premium and unamortized discount and financing costs of $2.4 million . We funded the redemption with borrowings under our Credit Agreement. On July 19, 2016, we closed a private placement of $400 million in aggregate principal amount of 6% senior unsecured notes due in 2024 (the “6% Senior Notes”). We used the net proceeds to repay indebtedness under our Credit Agreement. The 6% Senior Notes are unsecured and impose certain restrictive covenants, 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. We were in compliance with the restrictive covenants for the 6% Senior Notes as of June 30, 2017 . At any time when the 6% 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% Senior Notes. Indebtedness under the 6% Senior Notes is guaranteed by our wholly-owned subsidiaries. Long-term Debt The carrying amounts of our long-term debt are as follows: June 30, December 31, (In thousands) Credit Agreement Amount outstanding $ 843,000 $ 553,000 6% Senior Notes Principal 400,000 400,000 Unamortized debt issuance costs (6,261 ) (6,607 ) 393,739 393,393 6.5% Senior Notes Principal — 300,000 Unamortized discount and debt issuance costs — (2,481 ) — 297,519 Total long-term debt $ 1,236,739 $ 1,243,912 Interest Rate Risk Management We use interest rate swaps (derivative instruments) to manage our exposure to interest rate risk. As of June 30, 2017 , we had two interest rate swaps with identical terms that hedged our exposure to the cash flow risk caused by the effects of LIBOR changes on $150 million of Credit Agreement advances. The swaps effectively converted $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 June 30, 2017 , which equaled an effective interest rate of 2.99% . Both of these swap contracts matured on July 31, 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 June 30, 2017 , we had no ineffectiveness on our cash flow hedges. At June 30, 2017 , we had accumulated other comprehensive income of $0.1 million that related to our current cash flow hedging instruments. Approximately $0.1 million will be transferred from accumulated other comprehensive income into interest expense as interest is paid on the underlying swap agreements during the third quarter of 2017. Additional information on our interest rate swaps is as follows: Derivative Instrument Balance Sheet Location Fair Value Location of Offsetting Balance Offsetting Amount (In thousands) June 30, 2017 Interest rate swaps designated as cash flow hedging instrument: Variable-to-fixed interest rate swap contracts ($150 million of LIBOR-based debt interest) Other current assets $ 63 Accumulated other comprehensive income $ 63 $ 63 $ 63 December 31, 2016 Interest rate swaps designated as cash flow hedging instrument: Variable-to-fixed interest rate swap contracts ($150 million of LIBOR-based debt interest) Other current assets $ 91 Accumulated other $ 91 $ 91 $ 91 Interest Expense and Other Debt Information Interest expense consists of the following components: Six Months Ended June 30, 2017 2016 (In thousands) Interest on outstanding debt: Credit Agreement, net of interest on interest rate swaps $ 13,299 $ 10,284 6.5% Senior Notes 162 9,757 6% Senior Notes 12,000 — Amortization of discount and deferred debt issuance costs 1,536 1,376 Commitment fees and other 720 679 Total interest incurred 27,717 22,096 Less capitalized interest 430 285 Net interest expense $ 27,287 $ 21,811 Cash paid for interest $ 33,700 $ 20,736 Capital Lease Obligations Our capital lease obligations relate to vehicle leases with initial terms of 33 to 48 months.

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 2036. 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 June 30, 2017 , these agreements with HFC require minimum annualized payments to us of $322 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 $93.2 million and $79.2 million for the three months ended June 30, 2017 and 2016 , respectively, and $182.2 million and $162.0 million for the six months ended June 30, 2017 and 2016 , respectively. • HFC charged us general and administrative services under the Omnibus Agreement of $0.6 million for each of the three months ended June 30, 2017 and 2016 , and $1.2 million for each of the six months ended June 30, 2017 and 2016 . • We reimbursed HFC for costs of employees supporting our operations of $11.4 million and $9.5 million for the three months ended June 30, 2017 and 2016 , respectively, and $22.9 million and $19.4 million for the six months ended June 30, 2017 and 2016 , respectively. • HFC reimbursed us $1.5 million and $5.0 million for the three months ended June 30, 2017 and 2016 , respectively, and $2.8 million and $6.7 million for the six months ended June 30, 2017 and 2016 , respectively, for expense and capital projects. • We distributed $31.7 million and $25.3 million for the three months ended June 30, 2017 and 2016 , respectively, and $61.9 million and $49.8 million for the six months ended June 30, 2017 and 2016 , respectively, to HFC as regular distributions on its common units and general partner interest, including general partner incentive distributions. • Accounts receivable from HFC were $36.6 million and $42.6 million at June 30, 2017 , and December 31, 2016 , respectively. • Accounts payable to HFC were $7.3 million and $16.4 million at June 30, 2017 , and December 31, 2016 , respectively. • Revenues for the six months ended June 30, 2017 and 2016 , include $2.7 million and $5.5 million , respectively, of shortfall payments billed to HFC in 2016 and 2015, respectively. Deferred revenue in the consolidated balance sheets at June 30, 2017 and December 31, 2016 , includes $5.9 million and $5.6 million , respectively, relating to certain shortfall billings to HFC. It is possible that HFC may not exceed its minimum obligations to receive credit for any of the $5.9 million deferred at June 30, 2017 .

Partners' Capital [Abstract]
Partners' Equity	Partners’ Equity As of June 30, 2017 , HFC held 22,380,030 of our common units and the 2% general partner interest, which together constituted a 36% ownership interest in us. Additionally, HFC owned all incentive distribution rights. Continuous Offering Program We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million . For the six months ended June 30, 2017 , HEP issued 1,538,452 units under this program, providing $52.4 million in net proceeds. In connection with this program and to maintain the 2% general partner interest, HFC made capital contributions totaling $1.1 million . As of June 30, 2017 , HEP has issued 2,241,907 units under this program, providing $77.1 million in gross proceeds. We intend to use our net proceeds for general partnership purposes, which may include funding working capital, repayment of debt, acquisitions and capital expenditures. Amounts repaid under our credit facility may be reborrowed from time to time. 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 incentive distributions and other priority allocations are 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 June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands) General partner interest in net income $ 827 $ 540 $ 1,338 $ 1,170 General partner incentive distribution 17,501 12,137 34,128 23,609 Net loss attributable to Predecessor — (1,960 ) — (3,110 ) Total general partner interest in net income $ 18,328 $ 10,717 $ 35,466 $ 21,669 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 July 27, 2017 , we announced our cash distribution for the second quarter of 2017 of $0.6325 per unit. The distribution is payable on all common and general partner units and will be paid August 14, 2017 , to all unitholders of record on August 7, 2017 . 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 June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands, except per unit data) General partner interest in distribution $ 1,188 $ 978 $ 2,336 $ 1,927 General partner incentive distribution 17,501 12,137 34,128 23,609 Total general partner distribution 18,689 13,115 36,464 25,536 Limited partner distribution 40,682 34,575 80,314 68,302 Total regular quarterly cash distribution $ 59,371 $ 47,690 $ 116,778 $ 93,838 Cash distribution per unit applicable to limited partners $ 0.6325 $ 0.5850 $ 1.2525 $ 1.1600 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.

Net Income per Limited Partner Unit [Abstract]
Net Income Per Limited Partner Unit	Net Income Per Limited Partner Unit Net income per unit applicable to the limited partners is computed using the two-class method, because we have more than one class of participating securities. The classes of participating securities as of June 30, 2017 , included common units, general partner units and incentive distribution rights (IDRs). To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings. The dilutive securities are immaterial for all periods presented. When our financial statements are retrospectively adjusted after a dropdown transaction, the earnings of the acquired business, prior to the closing of the transaction, are allocated entirely to our general partner and presented as net income (loss) attributable to Predecessors. The earnings per unit of our limited partners prior to the close of the transaction do not change as a result of the dropdown. After the closing of a dropdown transaction, the earnings of the acquired business are allocated in accordance with our partnership agreement as previously described. For purposes of applying the two-class method including the allocation of cash distributions in excess of earnings, net income per limited partner unit is computed as follows: Three Months Ended Six Months Ended 2017 2016 2017 2016 (In thousands) Net income attributable to the partners $ 41,335 $ 39,120 $ 66,898 $ 82,095 Less: General partner’s distribution declared (including IDRs) (18,689 ) (13,115 ) (36,464 ) (25,536 ) Limited partner’s distribution declared on common units (40,682 ) (34,575 ) (80,314 ) (68,302 ) Distributions in excess of net income attributable to the partners $ (18,036 ) $ (8,570 ) $ (49,880 ) $ (11,743 ) General Partner (including IDRs) Limited Partners’ Common Units Total (In thousands, except per unit data) Three Months Ended June 30, 2017 Net income attributable to the partners: Distributions declared $ 18,689 $ 40,682 $ 59,371 Distributions in excess of net income attributable to the partners (361 ) (17,675 ) (18,036 ) Net income attributable to the partners $ 18,328 $ 23,007 $ 41,335 Weighted average limited partners' units outstanding 64,086 Limited partners' per unit interest in earnings - basic and diluted $ 0.36 Three Months Ended June 30, 2016 Net income attributable to the partners: Distributions declared $ 13,115 $ 34,575 $ 47,690 Distributions in excess of net income attributable to the partners (171 ) (8,399 ) (8,570 ) Net income attributable to the partners $ 12,944 $ 26,176 $ 39,120 Weighted average limited partners' units outstanding 58,865 Limited partners' per unit interest in earnings - basic and diluted $ 0.45 General Partner (including IDRs) Limited Partners’ Common Units Total (In thousands, except per unit data) Six Months Ended June 30, 2017 Net income attributable to partnership: Distributions declared $ 36,464 $ 80,314 $ 116,778 Distributions in excess of net income attributable to partnership (998 ) (48,882 ) (49,880 ) Net income attributable to partnership $ 35,466 $ 31,432 $ 66,898 Weighted average limited partners' units outstanding 63,602 Limited partners' per unit interest in earnings - basic and diluted $ 0.49 Six Months Ended June 30, 2016 Net income attributable to partnership: Distributions declared $ 25,536 $ 68,302 $ 93,838 Distributions in excess of net income attributable to partnership (234 ) (11,509 ) (11,743 ) Net income attributable to partnership $ 25,302 $ 56,793 $ 82,095 Weighted average limited partners' units outstanding 58,761 Limited partners' per unit interest in earnings - basic and diluted $ 0.96

The accrued environmental liability, net of expected recoveries from indemnifying parties, reflected in our consolidated balance sheets was $6.5 million and $7.1 million at June 30, 2017 , and December 31, 2016 , respectively, of which $4.9 million and $5.4 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 June 30, 2017 , and December 31, 2016 , our consolidated balance sheets included additional accrued environmental liabilities of $0.8 million and $0.9 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.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segments Although financial information is reviewed by our chief operating decision makers from a variety of perspectives, they view the business in two operating segments: pipelines and terminals, and refinery processing units. These operating segments adhere to the accounting polices used for our consolidated financial statements. The pipelines and terminals segment has been aggregated as both pipeline and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements. We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific operating segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable operating segment.

Supplemental Guarantor / Non-Guarantor Financial Information [Abstract]
Supplemental Guarantor / Non-Guarantor Financial Information	Supplemental Guarantor/Non-Guarantor Financial Information Obligations of HEP (“Parent”) under the 6% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary’s guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied. The following financial information presents condensed consolidating balance sheets, statements of comprehensive income, and statements of cash flows of the Parent, the Guarantor Subsidiaries and the Non-Guarantor Subsidiaries. The information has been presented as if the Parent accounted for its ownership in the Guarantor Subsidiaries, and the Guarantor Restricted Subsidiaries accounted for the ownership of the Non-Guarantor Non-Restricted Subsidiaries, using the equity method of accounting. In conjunction with the preparation of our Condensed Consolidating Balance Sheet and Statements of Comprehensive Income included below, we identified and corrected the presentation of noncontrolling interests presented in the eliminations column in prior periods to reflect such balances and activity within the respective guarantor and non-guarantor subsidiaries columns.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation and Common Control Transactions The consolidated financial statements include our accounts, our Predecessor's (defined below) and those of subsidiaries and joint ventures that we control. All significant intercompany transactions and balances have been eliminated. Most of our acquisitions from HFC occurred while we were a consolidated variable interest entity (“VIE”) of HFC. Therefore, as an entity under common control with HFC, we recorded these acquisitions on our balance sheets at HFC's historical basis instead of our purchase price or fair value. GAAP requires transfers of a business between entities under common control to be accounted for as though the transfer occurred as of the beginning of the period of transfer, and prior period financial statements and financial information are retrospectively adjusted to include the historical results and assets of the acquisitions from HFC for all periods presented prior to the effective dates of each acquisition. We refer to the historical results of the acquisitions prior to their respective acquisition dates as those of our "Predecessor." Many of these transactions are cash purchases and do not involve the issuance of equity; however, GAAP requires the retrospective adjustment of financial statements. Therefore, in such transactions, the prior year balance sheet includes as equity the amount of cost incurred by HFC to that date. See “Acquisitions” below for further discussion as well as effects of the retrospective adjustments.
New Accounting Pronouncements, Policy [Policy Text Block]	Accounting Pronouncements Adopted During the Periods Presented 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 adopted this standard as of January 1, 2016. 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 and six months ended June 30, 2016, and in connection with the purchase of HFC’s Woods Cross refinery units on October 1, 2016, we reduced net income by $2.0 million and $2.9 million , respectively, for the three and six months ended June 30, 2016 . This reduction had no impact on the historical earnings per limited partner unit. Share-Based Compensation In March 2016, an accounting standard update was issued which simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. We adopted this standard effective January 1, 2017, with no impact to our financial condition, results of operations and cash flows. As permitted by the standard, we continue to account for forfeitures on an estimated basis. Accounting Pronouncements Not Yet Adopted 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, and we intend to account for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment is recorded to retained earnings as of the date of initial application. Our preparation for adoption of this standard is in progress, and we are currently evaluating terms, conditions and our performance obligations of our existing contracts with customers. We are evaluating the effect of this standard on our revenue recognition policies and whether it will have a material impact on our financial condition or results of operations. Business Combinations In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard has an effective date of January 1, 2018, and we are evaluating its impact. 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.

Segment Reporting Information [Line Items]
Segment Reporting Disclosure [Text Block]	Segments Although financial information is reviewed by our chief operating decision makers from a variety of perspectives, they view the business in two operating segments: pipelines and terminals, and refinery processing units. These operating segments adhere to the accounting polices used for our consolidated financial statements. The pipelines and terminals segment has been aggregated as both pipeline and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements. We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific operating segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable operating segment.
