Résumé
EPA is finalizing its determination that the San Joaquin Valley nonattainment area (SJV or the Valley) in California has attained the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). This determination is based upon monitored air quality data for the PM-10 NAAQS during the years 2003- 2005. The SJV continues to attain the PM-10 NAAQS in 2006 based on the latest available quality assured data. EPA is also finalizing its determination that, because the SJV has attained the PM-10 NAAQS, certain Clean Air Act (CAA or the Act) requirements are not applicable for as long as the SJV continues to attain the PM-10 NAAQS.
