Summary: The CASAC, which comprises seven members appointed by the EPA Administrator, was established under section 109(d)(2) of the Clean Air Act (42 U.S.C. 7409) as an independent scientific advisory committee, in part to provide advice, information and recommendations on the scientific and technical aspects of issues related to air quality criteria and national ambient air quality standards (NAAQS) under sections 108 and 109 of the Act. The CASAC is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The CASAC PM Review Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

The teleconference is a continuation of the PM Review Panel's peer review of the EPA Air Quality Criteria for Particulate Matter (Fourth External Review Draft). Specifically, this meeting will be held to discuss the revisions to Chapter 9 (Integrative Synthesis) of the Fourth External Review Draft of the Air Quality Criteria Document (AQCD) for PM. The report from the CASAC PM Review Panel's last meeting to review this draft document, held on July 20-21, 2004, will soon be posted on the SAB Web site at:​sab.

Background: EPA is in the process of updating, and revising where appropriate, the AQCD for PM as issued in 1996. Section 109(d)(1) of the Clean Air Act (CAA) requires that EPA carry out a periodic review and revision, where appropriate, of the air quality criteria and the National Ambient Air Quality Standards (NAAQS) for “criteria” air pollutants such as PM. On June 30, 2003, the National Center for Environmental Assessment (NCEA), within EPA's Office of Research and Development, made available for public review and comment a Fourth External Review Draft of a revised document, EPA Air Quality Criteria for Particulate Matter. Under CAA sections 108 and 109, the purpose of the revised document is to provide an assessment of the latest scientific information on the effects of airborne PM on the public health and welfare, for use in EPA's current review of the NAAQS for PM. Detailed summary information on the history of the current draft AQCD for PM is contained in a previous Federal Register notice (68 FR 36985, June 20, 2003). The EPA Air Quality Criteria for Particulate Matter (Fourth External Review Draft), and the revised chapters of this draft document, can be viewed and downloaded from the NCEA Web site at:​ncea/​cfm/​partmatt.cfm. Any questions concerning the draft document should be directed to Dr. Robert Elias, NCEA-RTP, via telephone: (919) 541-1818; or e-mail at:
