The Environmental Protection Agency (EPA) is proposing to conditionally approve the portions of revisions to the Georgia State Implementation Plan (SIP), submitted by the Georgia Department of Natural Resources (DNR), Environmental Protection Division (GAEPD), addressing the Clean Air Act (CAA or Act) visibility transport (prong 4) infrastructure SIP requirements for the 2008 8-hour Ozone, 2010 1- hour Nitrogen Dioxide (NO2), 2010 1-hour Sulfur Dioxide (SO2), and 2012 annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, commonly referred to as an ``infrastructure SIP.'' Specifically, EPA is proposing to conditionally approve the prong 4 portions of Georgia's March 6, 2012, 8-hour Ozone infrastructure SIP submission; March 25, 2013, 2010 1-hour NO2 infrastructure SIP submission; October 22, 2013, 2010 1- hour SO2 infrastructure SIP submission; and December 14, 2015, 2012 annual PM2.5 infrastructure SIP submission. All other applicable infrastructure requirements for these SIP submissions have been or will be addressed in separate rulemakings.
