## Abstract

On March 14, 1995, the Illinois Environmental Protection Agency (IEPA) formally submitted three federally enforceable State operating permits (FESOPs) to the United States Environmental Protection Agency (USEPA). These permits contained enforceable sulfur dioxide (SO<INF>2) emission limitations for three industrial facilities in the Granite City area of Madison County, Illinois. The limitations are intended to address modeled violations of the SO<INF>2 National Ambient Air Quality Standards (NAAQS). USEPA has determined that the three FESOPs are adequate as revisions to Illinois' State Implementation Plan (SIP) for sulfur dioxide (SO<INF>2) as it applies to Madison County, and as such, address the previously modeled violations of the SO<INF>2 NAAQS.
