In today's action, EPA finds that 28 States and the District of Columbia contribute significantly to nonattainment of the national ambient air quality standards (NAAQS) for fine particles (PM<INF>2.5</INF>) and/or 8-hour ozone in downwind States. The EPA is requiring these upwind States to revise their State implementation plans (SIPs) to include control measures to reduce emissions of sulfur dioxide (SO<INF>2</INF>) and/or nitrogen oxides (NO<INF>X</INF>). Sulfur dioxide is a precursor to PM<INF>2.5</INF> formation, and NO<INF>X</INF> is a precursor to both ozone and PM<INF>2.5</INF> formation. Reducing upwind precursor emissions will assist the downwind PM<INF>2.5</INF> and 8-hour ozone nonattainment areas in achieving the NAAQS. Moreover, attainment will be achieved in a more equitable, cost- effective manner than if each nonattainment area attempted to achieve attainment by implementing local emissions reductions alone. Based on State obligations to address interstate transport of pollutants under section 110(a)(2)(D) of the Clean Air Act (CAA), EPA is specifying statewide emissions reduction requirements for SO<INF>2</INF> and NO<INF>X</INF>. The EPA is specifying that the emissions reductions be implemented in two phases. The first phase of NO<INF>X</INF> reductions starts in 2009 (covering 2009-2014) and the first phase of SO<INF>2</INF> reductions starts in 2010 (covering 2010- 2014); the second phase of reductions for both NO<INF>X</INF> and SO<INF>2</INF> starts in 2015 (covering 2015 and thereafter). The required emissions reductions requirements are based on controls that are known to be highly cost effective for electric generating units (EGUs). Today's action also includes model rules for multi-State cap and trade programs for annual SO<INF>2</INF> and NO<INF>X</INF> emissions for PM<INF>2.5</INF> and seasonal NO<INF>X</INF> emissions for ozone that States can choose to adopt to meet the required emissions reductions in a flexible and cost-effective manner. Today's action also includes revisions to the Acid Rain Program regulations under title IV of the CAA, particularly the regulatory provisions governing the SO<INF>2</INF> cap and trade program. The revisions are made because they streamline the operation of the Acid Rain SO<INF>2</INF> cap and trade program and/or facilitate the interaction of that cap and trade program with the model SO<INF>2</INF> cap and trade program included in today's action. In addition, today's action provides for the NO<INF>X</INF> SIP Call cap and trade program to be replaced by the CAIR ozone-season NO<INF>X</INF> trading program.

SUMMARY: In today's action, EPA finds that 28 States and the District of Columbia contribute significantly to nonattainment of the national ambient air quality standards (NAAQS) for fine particles (PM 2.5 ) and/or 8-hour ozone in downwind States. The EPA is requiring these upwind States to revise their State implementation plans (SIPs) to include control measures to reduce emissions of sulfur dioxide (SO 2 ) and/or nitrogen oxides (NO X ). Sulfur dioxide is a precursor to PM 2.5 formation, and NO X is a precursor to both ozone and PM 2.5 formation. Reducing upwind precursor emissions will assist the downwind PM 2.5 and 8-hour ozone nonattainment areas in achieving the NAAQS. Moreover, attainment will be achieved in a more equitable, cost-effective manner than if each nonattainment area attempted to achieve attainment by implementing local emissions reductions alone. Based on State obligations to address interstate transport of pollutants under section 110(a)(2)(D) of the Clean Air Act (CAA), EPA is specifying statewide emissions reduction requirements for SO 2 and NO X . The EPA is specifying that the emissions reductions be implemented in two phases. The first phase of NO X reductions starts in 2009 (covering 2009-2014) and the first phase of SO 2 reductions starts in 2010 (covering 2010-2014);…
