## Abstract

On September 14, 2012, the Georgia Department of Natural Resources, through the Georgia Environmental Protection Division (GA EPD), submitted a request to redesignate the Georgia portion of Chattanooga, TN-GA-AL fine particulate matter (PM<INF>2.5</INF>) nonattainment area (hereafter referred to as the "Chattanooga TN-GA-AL Area" or "Area") to attainment for the 1997 annual PM<INF>2.5</INF> national ambient air quality standards (NAAQS) and to approve a state implementation plan (SIP) revision containing a maintenance plan for the Chattanooga TN-GA-AL Area. The Georgia portion of Chattanooga TN- GA-AL Area is comprised of two Counties: Catoosa and Walker Counties in Georgia. EPA is approving the redesignation request and the related SIP revision for the Georgia portion of Chattanooga TN-GA-AL Area, including GA EPD's plan for maintaining attainment of the 1997 Annual PM<INF>2.5</INF> standard in the Chattanooga TN-GA-AL Area. EPA is also approving, into the Georgia SIP, the motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO<INF>x</INF>) and PM<INF>2.5</INF> for the year 2025 for the Georgia portion of Chattanooga TN-GA-AL Area. On April 23, 2013, and November 13, 2014, Alabama and Tennessee (respectively) submitted requests to redesignate the Alabama and Tennessee portions of the Chattanooga TN-GA-AL Area. EPA will be taking separate action on the requests from Alabama and Tennessee.
