Air Plan Approval; Georgia; Regional Haze Plan and Prong 4 (Visibility) for the 2012 PM2.5

The Environmental Protection Agency (EPA) is approving the portion of Georgia's July 26, 2017, State Implementation Plan (SIP) submittal changing reliance from the Clean Air Interstate Rule (CAIR) to the Cross-State Air Pollution Rule (CSAPR) for certain regional haze requirements. EPA is also converting the previous limited approval/ limited disapproval of Georgia's regional haze plan to a full approval and is removing the Federal Implementation Plan (FIP) for Georgia which replaced reliance on CAIR with reliance on CSAPR. Finally, EPA is converting the conditional approvals to full approvals for the visibility prong of Georgia's infrastructure SIP submittals for the 2012 Fine Particulate Matter (PM2.5), 2010 Nitrogen Dioxide (NO2), 2010 Sulfur Dioxide (SO2), and 2008 8-hour Ozone National Ambient Air Quality Standards (NAAQS).
