Air Plan Approval; Georgia; Atlanta Area Limited Maintenance Plan for the 1997 8-Hour Ozone NAAQS

The Environmental Protection Agency (EPA) is finalizing approval of a state implementation plan (SIP) revision submitted by the State of Georgia, through the Georgia Environmental Protection Division (EPD), on December 17, 2021. The SIP revision includes the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) Limited Maintenance Plan (LMP) for the Atlanta, Georgia Area (hereinafter referred to as the Atlanta Area or Area). The Atlanta Area consists of 20 counties in Georgia: Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding and Walton Counties. EPA is approving Georgia's LMP for the Atlanta Area because it provides for maintenance of the 1997 8-hour ozone NAAQS within the Area through the end of the second 10-year portion of the maintenance period. The effect of this action makes certain commitments related to maintenance of the 1997 8-hour ozone NAAQS in the Area federally enforceable as part of the Georgia SIP.
