Ozone and PM Attainment forecast with CAIR and with Other Clean Air Programs - 2010

Ozone and Fine Particle Nonattainment Areas* (April 2005) Projected Nonattainment Areas* in 2010 after Reductions from CAIR and Existing Clean Air Act Programs

Projections concerning future levels of air pollution in specific geographic locations were estimated using the best scientific models available. They are estimations, however, and should be characterized as such in any description. Actual results may vary significantly if any of the factors that influence air quality differ from the assumed values used in the projections shown here.

Nonattainment areas for both 8-hour ozone and fine particle pollution Nonattainment areas for fine particle pollution only . Nonattainment areas for 8-hour ozone pollution only

104 ozone nonattainment areas (408counties) 36 PM2.5 nonattainment areas with 195 counties 15 ozone nonattainment areas 19 PM2.5 nonattainment areas

*Maps show only those Nonattainment Areas in States covered by CAIR
