## Abstract

The Environmental Protection Agency (EPA) is approving a request submitted by the Indiana Department of Environmental Management (IDEM) on March 14, 2013, to revise the Indiana state implementation plan (SIP) solvent degreasing operation rule. The state's submission seeks to extend vapor pressure limitations (previously applying to four counties) state-wide, add certain exemptions and streamline the rule by repealing and consolidating certain provisions. There is also a revised definition for "cold cleaner degreaser."
