Abstract
EPA is approving revisions to the Indiana State Implementation Plan (SIP), submitted by the Indiana Department of Environmental Management (IDEM) to EPA on July 7, 2011. The SIP revision modifies Indiana's Prevention of Significant Deterioration (PSD) program to establish appropriate emission thresholds for determining which new stationary sources and modification projects become subject to Indiana's PSD permitting requirements for their greenhouse gas (GHG) emissions. EPA proposed approval of these regulatory revisions on June 17, 2011, and received no comments. This action affects major stationary sources in Indiana that have GHG emissions above the thresholds established in the PSD regulations.
