Abstract
The Environmental Protection Agency is approving revisions to particulate matter (PM<INF>10</INF>) emissions regulations for U.S. Steel-Gary Works and U.S. Steel-Gary Coke Operations, located in Lake County, Indiana. The Indiana Department of Environmental Management (IDEM) requested on June 13, 2003, and supplemented on October 3, 2003, that EPA approve this State Implementation Plan (SIP) revision, as an amendment to 326 Indiana Administrative Code (IAC) 6-1-10.1 and 326 IAC 6-1-10.2. The revisions to the rules reflect the closure of certain emission units, the addition of new emission units, and the installation of new control systems. These changes should result in decreased PM<INF>10</INF> emissions of approximately 350 tons per year (tpy). EPA is approving this request because it satisfies the requirements of the Clean Air Act (Act).
