Abstract
EPA is taking final action to approve changes to the Mississippi State Implementation Plan (SIP), submitted by the Mississippi Department of Environmental Quality (MDEQ) Division of Air Pollution Control to EPA on May 12, 2011. The May 12, 2011, SIP revision modifies Mississippi's New Source Review (NSR) Prevention of Significant Deterioration (PSD) permitting regulations to incorporate by reference, into the Mississippi SIP, federal NSR PSD requirements for the fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS) as promulgated in EPA's 2008 NSR PM<INF>2.5</INF> Implementation Rule and the 2010 PM<INF>2.5</INF> PSD Increment, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC) Rule. EPA is approving portions of Mississippi's May 12, 2011, SIP revision because they are consistent with the Clean Air Act (CAA or Act) and EPA regulations regarding NSR permitting.
