Equity Method Investments and Joint Ventures [Abstract]
Variable Interest Entities	Variable Interest Entities Holly Energy Partners HEP, a consolidated VIE, is a publicly held master limited partnership that was formed to acquire, own and operate the petroleum product and crude oil pipeline and terminal, tankage and loading rack facilities that support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. HEP also owns and operates refined product pipelines and terminals, located primarily in Texas, that serve Alon's refinery in Big Spring, Texas. As of December 31, 2013, we owned a 39% interest in HEP, including the 2% general partner interest. As the general partner of HEP, we have the sole ability to direct the activities that most significantly impact HEP's financial performance. We are the primary beneficiary of HEP's earnings and cash flows and therefore we consolidate HEP. See Note 21 for supplemental guarantor/non-guarantor financial information, including HEP balances included in these consolidated financial statements. HEP has two primary customers (including us) and generates revenues by charging tariffs for transporting petroleum products and crude oil though its pipelines, by charging fees for terminalling refined products and other hydrocarbons, and storing and providing other services at its storage tanks and terminals. Under our long-term transportation agreements with HEP (discussed further below), we accounted for 83% of HEP’s total revenues for the year ended December 31, 2013. We do not provide financial or equity support through any liquidity arrangements and / or debt guarantees to HEP. HEP has outstanding debt under a senior secured revolving credit agreement and its senior notes. With the exception of the assets of HEP Logistics Holdings, L.P., one of our wholly-owned subsidiaries and HEP’s general partner, HEP’s creditors have no recourse to our other assets. Any recourse to HEP’s general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. See Note 12 for a description of HEP’s debt obligations. HEP has risk associated with its operations. If a major customer of HEP were to terminate its contracts or fail to meet desired shipping or throughput levels for an extended period of time, revenue would be reduced and HEP could suffer substantial losses to the extent that a new customer is not found. In the event that HEP incurs a loss, our operating results will reflect HEP’s loss, net of intercompany eliminations, to the extent of our ownership interest in HEP at that point in time. HEP's recent acquisitions (2011 through present) are summarized below: UNEV Interest Transaction On July 12, 2012, HEP acquired from us our 75% interest in UNEV. We received consideration consisting of $260.0 million in cash and 1.0 million HEP common units. Legacy Frontier Tankage and Terminal Asset Transaction On November 9, 2011, HEP acquired from us certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries. We received non-cash consideration consisting of promissory notes with an aggregate principal amount of $150.0 million and 3.8 million HEP common units. Transportation Agreements HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring from 2019 through 2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP including UNEV (a consolidated subsidiary of HEP). Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments on July 1 at a rate based upon the percentage change in Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index. As of December 31, 2013, these agreements result in minimum annualized payments to HEP of $225.5 million. Our transactions with HEP including the acquisitions discussed above and fees paid under our transportation agreements with HEP and UNEV are eliminated and have no impact on our consolidated financial statements. HEP's recent common unit issuances (2011 through present) are summarized below: 2013 Issuances In March 2013, HEP closed on a public offering of 1,875,000 of its common units. Additionally, our wholly-owned subsidiary, HollyFrontier Holdings LLC, as a selling unitholder, closed on a public sale of 1,875,000 HEP common units held by it. HEP used net proceeds of $73.4 million to repay indebtedness incurred under its credit facility and for general partnership purposes. 2012 Issuances In July 2012, HEP issued 1.0 million of its common units to us as partial consideration for its purchase of our 75% interest in UNEV. 2011 Issuances In December 2011, HEP issued 1.5 million of its common units priced at $53.50 per unit. Aggregate net proceeds of $75.8 million were used to repay a portion of the $150 million in promissory notes issued to us in connection with HEP's November 2011 asset acquisition from us. This repayment to us is eliminated in our consolidated financial statements. In November 2011, HEP issued 3.8 million of its common units to us as partial consideration for its purchase from us of certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries. As a result of these transactions and resulting HEP ownership changes, we adjusted additional capital, other comprehensive income and equity attributable to HEP's noncontrolling interest holders to effectively reallocate a portion of HEP's equity among its unitholders. Sabine Biofuels We have a 50% ownership interest in Sabine Biofuels, an unconsolidated VIE. This investment, accounted for using the equity method of accounting, had a carrying amount of $8.5 million at December 31, 2013 and is classified as a noncurrent asset under “Intangibles and other” in our consolidated balance sheets.
