Abstract
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Kentucky, through the Kentucky Energy and Environment Cabinet by a letter dated November 16, 2018, for the purpose of addressing the Clean Air Act (CAA or Act) "good neighbor" 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 finalizing approval of Kentucky's November 16, 2018, SIP revision addressing prongs 1 and 2 to ensure that air emissions in Kentucky do not significantly contribute to nonattainment or interfere with maintenance of the 2010 1-hour NO<INF>2</INF> NAAQS in any other state.
