Air Quality Criteria for Particulate Matter (External Review Draft)

On or about August 27, 2004, the National Center for Environmental Assessment (NCEA), within EPA's Office of Research and Development, will make available for public review and comment a revised draft of Chapter 9 (integrative synthesis) of EPA's draft Air Quality Criteria for Particulate Matter (EPA/600/P-99/002bD). The revised draft chapter incorporates revisions made in response to earlier public external and Clean Air Act Scientific Advisory Committee (CASAC) reviews of the draft document. Under sections 108 and 109 of the Clean Air Act, the purpose of the Air Quality Criteria for Particulate Matter is to provide an assessment of the latest scientific information on the effects of airborne particulate matter (PM) on the public health and welfare for use in EPA's current review of the National Ambient Air Quality Standards (NAAQS) for PM.
