## Abstract

The EPA is approving a request from the Indiana Department of Environmental Management (IDEM) to revise the Indiana State Implementation Plan (SIP). The revision consists of the repeal of 326 IAC 6-1, and its replacement by new articles 326 IAC 6.5 and 326 IAC 6.8. 326 IAC 6.5 contains particulate matter emission limitations for sources in all counties in Indiana, with the exception of Lake County. Sources located in Lake County are addressed in 326 IAC 6.8. The revision does not change any control requirements or any other provisions in 326 IAC 6-1.
