The Environmental Protection Agency (EPA) is proposing to approve portions of revisions to the North Carolina State Implementation Plan (SIP), submitted by the North Carolina Department of Environment and Natural Resources (NC DENR), 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 approve the prong 4 portions of North Carolina's November 2, 2012, 2008 8-hour Ozone infrastructure SIP submission; August 23, 2013, 2010 1-hour NO<INF>2</INF> infrastructure SIP submission; March 18, 2014, 2010 1- hour SO<INF>2</INF> infrastructure SIP submission; and December 4, 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.
