Abstract
EPA is approving a request submitted by the Indiana Department of Environmental Management (IDEM) on January 30, 2013, to revise the Indiana State Implementation Plan (SIP) for particulate matter under the Clean Air Act (CAA). This submission contains the 24-hour fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) promulgated by EPA in 2006, and removes the annual coarse particle (PM<INF>10</INF>) NAAQS that EPA has previously revoked. The submission also asks EPA to approve into the SIP certain Federally regulated criteria pollutant definitions and abbreviations.
