## Abstract

EPA is approving a request submitted by the Indiana Department of Environmental Management on November 24, 2010, to revise the Indiana State Implementation Plan (SIP) under the Clean Air Act (CAA). These revisions address sulfur dioxide (SO<INF>2</INF>) and particulate matter (PM) limits for Cargill, Incorporated (Cargill) at its facility in Hammond (Lake County), Indiana. Indiana's SO<INF>2</INF> revisions tighten emission limits for some existing units at Cargill's Hammond facility and remove the references to other emission units that are no longer in operation, in accordance with the terms of a September 2005 Federal consent decree. The PM revisions reflect the permanent shutdown of, and changes in unit identification for other Cargill units.
