| 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 and loading rack facilities operation. We own and operate petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities 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 (“UNEV”), which owns a 427 -mile, 12 -inch refined products pipeline running from Woods Cross, Utah to Las Vegas, Nevada (the “UNEV Pipeline”), product terminals near Cedar City, Utah and Las Vegas, Nevada and related assets, and a 25% interest in SLC Pipeline LLC, which owns a 95 -mile intrastate crude oil pipeline system (the “SLC Pipeline”) that serves refineries in the Salt Lake City, Utah area. 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, and providing other services at our storage tanks and terminals. We do not take ownership of products that we transport, terminal or store, 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, 2014 . 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, 2015 . Acquisitions On August 31, 2015, we purchased a 50% interest in Frontier Pipeline Company, which owns a 289 -mile crude oil pipeline running from Casper, Wyoming to Frontier Station, Utah (the "Frontier Pipeline"), from an affiliate of Enbridge, Inc. for cash consideration of $54.6 million . Frontier Pipeline will continue to be operated by an affiliate of Plains All American Pipeline, L.P., which owns the remaining 50% interest. The Frontier Pipeline has a 72,000 barrel per day ("bpd") capacity and supplies Canadian and Rocky Mountain crudes to Salt Lake City area refiners through a connection to the SLC Pipeline. On November 1, 2015 , we acquired from Frontier 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 . We are a consolidated variable interest entity of HFC. Therefore, this transaction will be recorded as a transfer between entities under common control and reflect HFC's carrying basis in El Dorado Operating's assets and liabilities. Also, we will retrospectively adjust 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. Assuming this acquisition was effective as of September 30, 2015 , our assets, liabilities and partners' equity would have been retrospectively adjusted to include El Dorado Operating's assets, liabilities and partners' equity as presented below: September 30, December 31, (In thousands) Properties and equipment, net $ 60,320 $ 38,119 Accounts payable $ 776 $ 3,742 Partners' equity $ 59,544 $ 34,377 This retrospective adjustment will not have significant impact on our operating results prior to September 30, 2015 , since the hydrogen generation unit became operational in the third quarter of 2015 and the naphtha fractionation unit was not operational until the fourth quarter of 2015. 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. Debt Issuance Costs In April 2015, an accounting standard update was issued requiring debt issuance costs to be presented as a direct deduction from the carrying amount of the debt liability. The amount of deferred debt issuance costs reported in long-term assets was $4.3 million and $4.4 million as of September 30, 2015 and December 31, 2014 , respectively. This standard will become effective beginning with our 2016 reporting year. |

| 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: September 30, 2015 December 31, 2014 Financial Instrument Fair Value Input Level Carrying Value Fair Value Carrying Value Fair Value (In thousands) Assets: Interest rate swaps Level 2 $ — $ — $ 1,019 $ 1,019 Liabilities: 6.5% Senior notes Level 2 $ 297,067 $ 288,000 $ 296,579 $ 291,000 Interest rate swaps Level 2 834 834 1,065 1,065 $ 297,901 $ 288,834 $ 297,644 $ 292,065 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. |

We recorded the assets acquired and liabilities assumed at their fair values at the date of acquisition based on preliminary valuations. Substantially all of the purchase price was allocated to properties and equipment and no goodwill has been recorded. We expect to finalize the purchase price allocation during the fourth quarter of 2015. HFC is the main customer of this crude tank farm. We capitalized $0.7 million and $1.2 million in interest attributable to construction projects during the nine months ended September 30, 2015 and 2014 , respectively. Depreciation expense was $40.5 million and $41.4 million for the nine months ended September 30, 2015 and 2014 , respectively. |

| 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: September 30, December 31, (In thousands) Alon transportation agreement $ 59,933 $ 59,933 HFC transportation agreement 74,231 74,231 Other 50 — 134,214 134,164 Less accumulated amortization 58,672 53,461 $ 75,542 $ 80,703 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 $1.4 million and $1.9 million for the three months ended September 30, 2015 and 2014 , respectively, and $4.1 million and $5.5 million for the nine months ended September 30, 2015 and 2014 , respectively. Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS, our ultimate general partner, to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets at the El Dorado and Cheyenne refineries, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit. We have an incentive plan (“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 September 30, 2015 , we have three types of incentive-based awards outstanding, which are described below. The compensation cost charged against income was $1.3 million and $0.9 million for the three months ended September 30, 2015 and 2014 , respectively, and $2.9 million and $2.5 million for the the nine months ended September 30, 2015 and 2014 , 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 September 30, 2015 , 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 1,541,714 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 grant phantom units to certain employees, which vest over a period of one year. Vested units are paid in common units. Full ownership of the units does not transfer to the recipient until the units vest, and the recipients do not have voting or distribution rights on these units until they vest. The fair value of each restricted unit and phantom unit award is measured at the market price as of the date of grant and is amortized over the vesting period. A summary of restricted and phantom unit activity and changes during the nine months ended September 30, 2015 , is presented below: Restricted and Phantom Units Units Weighted Average Grant-Date Fair Value Outstanding at January 1, 2015 (nonvested) 126,077 $ 33.43 Forfeited (5,591 ) 33.51 Outstanding at September 30, 2015 (nonvested) 120,486 $ 33.42 As of September 30, 2015 , there was $1.1 million of total unrecognized compensation expense related to nonvested restricted unit and phantom unit grants, which is expected to be recognized over a weighted-average period of 1.1 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 based upon the growth in our distributable cash flow per common unit over the performance period, and vest over a period of three years. As of September 30, 2015 , estimated unit payouts for outstanding nonvested performance unit awards ranged between 100% and 150% . No performance units were granted during the nine months ended September 30, 2015 . Performance units granted in 2014 vest over a three-year performance period ending December 31, 2017. These performance units granted 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 nine months ended September 30, 2015 , is presented below: Performance Units Units Outstanding at January 1, 2015 (nonvested) 71,245 Vesting and transfer of common units to recipients (11,436 ) Outstanding at September 30, 2015 (Nonvested) 59,809 The grant-date fair value of performance units vested and transferred to recipients during the nine months ended September 30, 2015 , was $0.4 million . Based on the weighted average fair value of performance units outstanding at September 30, 2015 , of $2.2 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 0.9 years. |

| Debt Instruments [Abstract] | |
| Debt | Debt Credit Agreement In April 2015, we amended our senior secured revolving credit facility (the “Credit Agreement”) increasing the size of the Credit Agreement from $650 million to $850 million . 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 is 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 September 30, 2015 , 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 September 30, 2015 , 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. In March 2014, we redeemed the $150 million aggregate principal amount of 8.25% Senior Notes maturing March 2018 at a redemption cost of $156.2 million , at which time we recognized a $7.7 million early extinguishment loss consisting of a $6.2 million debt redemption premium and unamortized discount and financing costs of $1.5 million . We funded the redemption with borrowings under our Credit Agreement. Indebtedness under the 6.5% Senior Notes involves recourse to HEP Logistics, our general partner, and is guaranteed by our material, 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: September 30, December 31, (In thousands) Credit Agreement $ 654,000 $ 571,000 6.5% Senior Notes Principal 300,000 300,000 Unamortized discount (2,933 ) (3,421 ) 297,067 296,579 Total long-term debt $ 951,067 $ 867,579 Interest Rate Risk Management We use interest rate swaps (derivative instruments) to manage our exposure to interest rate risk. As of September 30, 2015 , we have three interest rate swaps that hedge our exposure to the cash flow risk caused by the effects of LIBOR changes on $305 million of Credit Agreement advances. Our first interest rate swap effectively converts $155 million of our LIBOR based debt to fixed rate debt having an interest rate of 0.99% plus an applicable margin of 2.00% as of September 30, 2015 , which equaled an effective interest rate of 2.99% . This swap contract matures in February 2016. We have two additional interest rate swaps with identical terms which 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 2.00% as of September 30, 2015 , which equaled an effective interest rate of 2.74% . 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 that these interest rate swaps are effective in offsetting the variability in interest payments on $305 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 $305 million of our variable rate debt. Any ineffectiveness is recorded directly to interest expense. As of September 30, 2015 , we had no ineffectiveness on our cash flow hedges. At September 30, 2015 , we have accumulated other comprehensive loss of $0.8 million that relates to our current cash flow hedging instruments. Approximately $0.7 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.

| Related Party Transactions [Abstract] | |
| Related Party Transactions | Related Party Transactions We serve HFC's refineries under long-term pipeline and terminal, tankage and throughput agreements expiring from 2019 to 2026. Under these agreements, HFC agrees to transport, store and throughput volumes of refined product and crude oil on our pipelines and terminal, tankage and loading rack facilities that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual tariff rate adjustments on July 1st each year based on the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index. As of September 30, 2015 , these agreements with HFC will result in minimum annual payments to us of $236.6 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 $2.4 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 $73.7 million and $67.5 million for the three months ended September 30, 2015 and 2014 , respectively, and $214.3 million and $203.8 million for the nine months ended September 30, 2015 and 2014 , respectively. • HFC charged us general and administrative services under the Omnibus Agreement of $0.6 million for each of the three months ended September 30, 2015 and 2014 , and $1.8 million and $1.7 million for nine months ended September 30, 2015 and 2014 , respectively. • We reimbursed HFC for costs of employees supporting our operations of $8.5 million and $9.9 million for the three months ended September 30, 2015 and 2014 , respectively, and $24.7 million and $28.7 million for the nine months ended September 30, 2015 and 2014 , respectively. • HFC reimbursed us $3.0 million and $3.1 million for the three months ended September 30, 2015 and 2014 , respectively, for certain reimbursable costs and capital projects and $10.0 million and $11.6 million for the nine months ended September 30, 2015 and 2014 , respectively. • We distributed $22.9 million and $20.4 million for the three months ended September 30, 2015 and 2014 , respectively, to HFC as regular distributions on its common units and general partner interest, including general partner incentive distributions. For the nine months ended September 30, 2015 and 2014 , we distributed $66.8 million and $59.5 million , respectively • Accounts receivable from HFC were $26.1 million and $33.4 million at September 30, 2015 , and December 31, 2014 , respectively. • Accounts payable to HFC were $3.7 million and $5.2 million at September 30, 2015 , and December 31, 2014 , respectively. • Revenues for the nine months ended September 30, 2015 and 2014 , include $6.6 million and $8.2 million , respectively, of shortfall payments billed in 2014 and 2013, as HFC did not exceed its minimum volume commitment in any of the subsequent four quarters. Deferred revenue in the consolidated balance sheets at September 30, 2015 , and December 31, 2014 , includes $6.0 million and $7.3 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 $6.0 million deferred at September 30, 2015 . |

| Partners' Capital [Abstract] | |
| Partners' Equity | Partners’ Equity As of September 30, 2015 , HFC held 22,380,030 of our common units and the 2% general partner interest, which together constituted a 39% ownership interest 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 September 30, Nine Months Ended September 30, 2015 2014 2015 2014 (In thousands) General partner interest in net income $ 483 $ 423 $ 1,344 $ 1,051 General partner incentive distribution 10,347 8,517 29,491 24,283 Total general partner interest in net income $ 10,830 $ 8,940 $ 30,835 $ 25,334 In addition to the allocation of net income as presented above, the consolidated statement of partners equity for the nine months ended September 30, 2015 , reflects a cumulative revision of net income allocations between the general partnership interest and common units of approximately $8.8 million for net income related to years ended 2014 and prior. This revision had no impact on historical limited partners’ per unit interest in earnings. 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 October 22, 2015 , we announced our cash distribution for the third quarter of 2015 of $0.555 per unit. The distribution is payable on all common and general partner units and will be paid November 13, 2015 , to all unitholders of record on November 2, 2015 . 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 September 30, Nine Months Ended September 30, 2015 2014 2015 2014 (In thousands, except per unit data) General partner interest in distribution $ 901 $ 825 $ 2,639 $ 2,422 General partner incentive distribution 10,347 8,517 29,491 24,283 Total general partner distribution 11,248 9,342 32,130 26,705 Limited partner distribution 32,554 30,648 96,051 90,625 Total regular quarterly cash distribution $ 43,802 $ 39,990 $ 128,181 $ 117,330 Cash distribution per unit applicable to limited partners $ 0.5550 $ 0.5225 $ 1.6375 $ 1.5450 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 [Text Block] | Environmental We incurred no expense for environmental remediation obligations for the three months ended September 30, 2015 and 2014 . For the nine months ended September 30, 2015 and 2014 , we incurred expenses of $4.2 million and $0.7 million , respectively, for environmental remediation obligations. During the nine months ended September 30, 2015 , we increased certain environmental cost accruals to reflect revisions to the cost estimates and the time frame for which the related environmental remediation and monitoring activities are expected to occur. The accrued environmental liability reflected in our consolidated balance sheets was $14.9 million and $12.0 million at September 30, 2015 and December 31, 2014 , respectively, of which $12.0 million and $8.7 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 September 30, 2015 , and December 31, 2014 , our accrued environmental liability included $6.4 million and $6.8 million , respectively, for HFC indemnified liabilities. In addition, as of September 30, 2015 , and December 31, 2014 , $6.4 million and $6.8 million , respectively, was included in other assets representing amounts due from HFC related to indemnifications for environmental remediation liabilities. |

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.

| 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. Debt Issuance Costs In April 2015, an accounting standard update was issued requiring debt issuance costs to be presented as a direct deduction from the carrying amount of the debt liability. The amount of deferred debt issuance costs reported in long-term assets was $4.3 million and $4.4 million as of September 30, 2015 and December 31, 2014 , respectively. This standard will become effective beginning with our 2016 reporting year. |
