Through this supplemental notice of proposed rulemaking ("supplemental proposal" or "SNPRM"), the Environmental Protection Agency (EPA) is supplementing its proposed approval of state implementation plan (SIP) submissions from Florida, Georgia, North Carolina, and South Carolina (four Southeastern States), addressing the Clean Air Act (CAA or Act) interstate transport requirements for the 2015 8-hour ozone National Ambient Air Quality Standard (NAAQS or standard). Specifically, EPA is proposing to rely on updated analysis using a 2021 analytic year to support the proposed finding that each state's implementation plan contains adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state.
The agency’s own summary, as published.
