The Environmental Protection Agency (EPA) is proposing to disapprove the visibility transport (prong 4) portions of revisions to the Mississippi State Implementation Plan (SIP), submitted by the Mississippi Department of Environmental Quality (MDEQ), addressing the Clean Air Act (CAA or Act) 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 disapprove the prong 4 portions of Mississippi's May 29, 2012, 2008 8-hour Ozone infrastructure SIP submission; July 26, 2012, 2008 8-hour Ozone infrastructure SIP resubmission; February 28, 2013, 2010 1-hour NO<INF>2</INF> infrastructure SIP submission; June 20, 2013, 2010 1-hour SO<INF>2</INF> infrastructure SIP submission; and December 8, 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.
