The Environmental Protection Agency (EPA) is approving an Arizona state implementation plan (SIP) revision for attaining the 2010 1-hour sulfur dioxide (SO2) primary national ambient air quality standard (NAAQS or ``standard'') for the Miami, Arizona SO2 nonattainment area (NAA). This SIP revision (hereinafter called the ``Miami SO2 Plan'' or ``Plan'') includes Arizona's attainment demonstration and other elements required under the Clean Air Act (CAA or ``Act'').
