Abstract
The Environmental Protection Agency (EPA) is approving a revision to the Mississippi State Implementation Plan (SIP), submitted by the Mississippi Department of Environmental Quality, on May 23, 2016, addressing the Clean Air Act (CAA or Act) interstate transport (prongs 1 and 2) infrastructure SIP requirements for the 2010 1-hour Nitrogen Dioxide (NO<INF>2</INF>) National Ambient Air Quality Standard (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 approving Mississippi's May 23, 2016, SIP submission addressing prongs 1 and 2, to ensure that air emissions in the State do not significantly contribute to nonattainment or interfere with maintenance of the 2010 1-hour NO<INF>2</INF> NAAQS in any other state.
