16 Successes: Now meeting all the 1970’s and 1980’s Now meeting all the 1970’s and 1980’s Air Quality Standards Air Quality Standards Challenges: Ozone – 8 hour standard PM-2.5 PM-2.5

17 March 2005 Ozone and Fine Particle Nonattainment Areas 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 Source: EPA Note: Southern California is the only area in the Western U.S. with red areas (both 8-hour ozone and PM2.5)
