## Abstract

EPA is approving revisions to total suspended particulate (TSP) and Sulfur Dioxide (SO<INF>2</INF>) emissions regulations for National Starch and Chemical Company (National Starch), and TSP regulations for Allison Transmission (Allison). Both of these facilities are located in Marion County, Indiana. The Indiana Department of Environmental Management (IDEM) submitted the revised regulations on February 3, 1999, August 30, 1999, and May 17, 2000, as amendments to its State Implementation Plan (SIP). The revisions include the relaxation of some limits, the tightening of one limit, and the elimination of limits for several sources which are no longer operating. The revisions also include the combination of annual emissions limits for several boilers, and recordkeeping requirements. These SIP revisions results in an overall decrease in allowed TSP emissions of about 406 tons per year (tpy) for National Starch, and no change in overall annual emissions for Allison.
