Ozone Transport Commission Special Meeting Bill Wehrum Acting Assistant Administrator U.S. EPA, Office of Air and Radiation February 22, 2006

Ozone and PM Attainment forecast with CAIR and with Other Clean Air Programs - 2010 Ozone and Fine Particle Nonattainment Projected Nonattainment Areas* in 2010 after Reductions Areas* (April 2005) from CAIR and Existing Clean Air Act Programs 104 ozone nonattainment areas (408counties) 15 ozone 36 PM 2.5 nonattainment areas 19 PM2.5 nonattainment areas nonattainment areas with 195 counties *Maps show only those Nonattainment Areas in States covered by CAIR Nonattainment areas for 8-hour ozone pollution only Nonattainment areas for fine particle pollution only . Projections concerning future levels of air pollution in specific geographic locations were estimated using the best scientific models available. They are estimations, however, and Nonattainment areas for should be characterized as such in any description. Actual results may vary significantly if both 8-hour ozone any of the factors that influence air quality differ from the assumed values used in the and fine particle pollution projections shown here.
