## Abstract

EPA is approving Indiana's modifications to its Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) rules. The amendments include grammatical changes, corrections to numbering, addition of definitions consistent with Federal PSD and NNSR regulations, and removal of references to provisions which were vacated in the Federal rules. Indiana submitted these rule revisions to EPA for approval on November 24, 2010. They are consistent with the current Federal PSD and NNSR regulations.
