Clean Air Act Reclassification; Wallula, Washington Particulate Matter (PM10) Nonattainment Area

EPA proposes to determine that the Wallula nonattainment area has not attained the National Ambient Air Quality Standards for particulate matter with an aerodynamic diameter of less than or equal to 10 microns (PM 10 ) by the attainment date of December 31, 1997, as required by the Clean Air Act. EPA's proposed finding is based on EPA's review of monitored air quality data reported for the years 1995 through 1999. If EPA takes final action on this proposal, the Wallula PM 10 nonattainment area will be reclassified by operation of law as a serious PM 10 nonattainment area.
