Abstract
The Environmental Protection Agency (EPA) is approving a request submitted on March 14, 2013, and supplemented on November 17, 2014, by the Indiana Department of Environmental Management (IDEM) to revise the state implementation plan (SIP) for lead. The submittal updates Indiana's lead rule at Title 326 of the Indiana Administrative Code (IAC), Article 15. It also amends 326 IAC Article 20, to incorporate some of the provisions of EPA's National Emission Standard for Hazardous Air Pollutants (NESHAP) for secondary lead smelters. IDEM made the revisions to increase the stringency and clarity of Indiana's lead SIP rules.
