Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	10. Commitments and Contingent Liabilities SunCoke Energy is party to an omnibus agreement pursuant to which we will provide remarketing efforts to the Partnership upon the occurrence of certain potential adverse events under certain coke sales agreements, indemnification of certain environmental costs and preferential rights for growth opportunities. The United States Environmental Protection Agency (the “EPA”) has issued Notices of Violations (“NOVs”) for our Haverhill and Granite City cokemaking facilities which stem from alleged violations of our air emission operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent decree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment, which was paid in December 2014, as well as capital projects already underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City facilities. We anticipate spending approximately $130 million related to these projects, of which we have spent approximately $90 million to date. The remaining capital is expected to be spent through the first quarter of 2019. A portion of the proceeds from the Partnership offering and subsequent dropdowns are being used to fund $119 million of these environmental remediation projects. SunCoke Energy has also received NOVs, a Finding of Violation ("FOV"), and information requests from the EPA related to our Indiana Harbor cokemaking facility. After initial discussions with the EPA and the Indiana Department of Environmental Management (“IDEM”), resolution of the NOVs was postponed by mutual agreement because of ongoing discussions regarding the NOVs at Haverhill and Granite City. In January 2012, the Company began working in a cooperative manner to address the allegations with the EPA, the IDEM and Cokenergy, Inc., an independent power producer that owns and operates an energy facility, including heat recovery equipment and a flue gas desulfurization system, that processes hot flue gas from our Indiana Harbor facility to produce steam and electricity and to reduce the sulfur and particulate content of such flue gas. The parties are meeting regularly in 2016. Capital projects are underway to address items that may be required in conjunction with a settlement of the NOVs. Settlement may require payment of a penalty for alleged past violations as well as undertaking capital projects to enhance reliability and environmental performance. At this time, SunCoke Energy cannot yet assess any additional injunctive relief or potential monetary penalty and any potential future citations. The Company is unable to determine a range of probable or reasonably possible loss. The Company is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Company. Management of the Company believes that any liability which may arise from claims would not have a material adverse impact on our consolidated financial statements.
