The Environmental Protection Agency (EPA) is proposing to conditionally approve the portions of revisions to the South Carolina State Implementation Plan (SIP), submitted by the South Carolina Department of Health and Environmental Control (SC DHEC), 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 (NO<INF>2</INF>), 2010 1-hour Sulfur Dioxide (SO<INF>2</INF>), and 2012 annual Fine Particulate Matter (PM<INF>2.5</INF>) 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 South Carolina's July 17, 2008, 8-hour Ozone infrastructure SIP submission; April 30, 2014, 2010 1-hour NO<INF>2</INF> infrastructure SIP submission; May 8, 2014, 2010 1-hour SO<INF>2</INF> infrastructure SIP submission; and December 18, 2015, 2012 annual PM<INF>2.5</INF> infrastructure SIP submission. All other applicable infrastructure requirements for these SIP submissions have been or will be addressed in separate rulemakings.
