## Abstract

The Environmental Protection Agency (EPA) is approving a request submitted by the Indiana Department of Environmental Management (IDEM) on June 1, 2015, to revise the Indiana state implementation plan (SIP) for sulfur dioxide (SO<INF>2</INF>). The revision updates information regarding Walsh and Kelly, Incorporated, a hot mix asphalt plant located in Griffith, Lake County, Indiana. Walsh and Kelly, Incorporated, is replacing its aggregate drum dryer. The revision does not change any of the SO<INF>2</INF> control requirements and will not result in an increase in SO<INF>2</INF> emissions.
