1. General Description of Business SunCoke Energy Partners, L.P., (the "Partnership", "we", "our", and "us") primarily produces coke used in the blast furnace production of steel. Coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. We also provide handling and/or mixing services of coal and other aggregates at our logistics terminals. At June 30, 2018 , we owned a 98 percent interest in Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown") and Gateway Energy and Coke Company, LLC ("Granite City") and SunCoke Energy, Inc. ("SunCoke") owned the remaining 2 percent ownership interest in each of Haverhill, Middletown, and Granite City. The Partnership also owns a 100 percent interest in all of its logistics terminals, which consist of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT") and SunCoke Lake Terminal, LLC ("Lake Terminal"). At June 30, 2018 , SunCoke, through a subsidiary, owned a 60.4 percent limited partnership interest in us and indirectly owned and controlled our general partner, which holds a 2.0 percent general partner interest in us and all of our incentive distribution rights ("IDR"). Our cokemaking ovens have collective capacity to produce 2.3 million tons of coke annually and utilize efficient, modern heat recovery technology designed to combust the coals volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. This differs from by-product cokemaking, which seeks to repurpose the coals liberated volatile components for other uses. We have constructed the only greenfield cokemaking facilities in the United States ("U.S.") in approximately 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process. We provide steam pursuant to steam su
