EPA is taking final action to approve changes to the Tennessee State Implementation Plan (SIP), submitted by the Tennessee Department of Environment and Conservation (TDEC) through the Division of Air Pollution Control to EPA on July 29, 2011. The July 29, 2011, SIP revision modifies Tennessee's New Source Review (NSR) Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) programs. Tennessee's July 29, 2011, SIP revision proposes to incorporate, into the Tennessee SIP, NSR provisions for PM<INF>2.5</INF> as amended in EPA's 2008 NSR PM<INF>2.5</INF> Implementation Rule. Also, Tennessee's July 29, 2011, SIP revision makes a corrective and clarifying administrative change to rule 1200- 03-09-.01. EPA is approving Tennessee's July 29, 2011, SIP revision because it is consistent with the Clean Air Act (CAA or Act) and EPA regulations regarding NSR permitting.
