## Abstract

On July 10, 2006, EPA proposed partial approval of revisions to Indiana's prevention of significant deterioration (PSD) and nonattainment new source review (NSR) construction permit programs. EPA received comments on this proposal on August 9, 2006. An adverse comment regarding the inclusion of hazardous air pollutants (HAPs) in Indiana's PSD rules was received. Subsequently, on January 17, 2007, the Indiana Department of Environmental Management (IDEM) requested the withdrawal of the portion of this submittal pertaining to HAPs. EPA is partially approving the portions of the Indiana rule that were proposed for approval on July 10, 2006 and were not withdrawn on January 17, 2007. As noted in the July 10, 2006, notice, we are not taking action on the Clean Unit and Pollution Control Project (PCP) portions of the Indiana rule.
