## Abstract

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Georgia, through the Georgia Environmental Protection Division (Georgia EPD), via a letter dated July 24, 2018, and the State of Tennessee, through the Tennessee Department of Environment & Conservation (TDEC), via a letter dated May 14, 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 approving these SIP revisions addressing prongs 1 and 2 to ensure that air emissions in each of these two states do not significantly contribute to nonattainment or interfere with maintenance of the 2010 1-hour NO<INF>2</INF> NAAQS in any other state.
