The Environmental Protection Agency (EPA) is proposing to approve an Arizona state implementation plan (SIP) revision for attaining the 1-hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS or "standard") for the Miami SO<INF>2</INF> nonattainment area (NAA). This SIP revision (hereinafter called the "Miami SO<INF>2</INF> Plan" or "Plan") includes Arizona's attainment demonstration and other elements required under the Clean Air Act (CAA or "Act"). In addition to an attainment demonstration, the Plan addresses the requirement for meeting reasonable further progress toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology, base-year and projected emission inventories, enforceable emissions limitations and control measures, and contingency measures. The EPA proposes to conclude that Arizona has appropriately demonstrated that the Plan provides for attainment of the 2010 1-hour primary SO<INF>2</INF> NAAQS in the Miami SO<INF>2</INF> NAA by the attainment date of October 4, 2018 and that the Plan meets the other applicable requirements under the CAA.
