Background: Section 109(d)(1) of the Clean Air Act (CAA or Act) requires that EPA periodically review and revise, as appropriate, the air quality criteria and the national ambient air quality standards (NAAQS) for the six “criteria” air pollutants, including ambient ozone. EPA is in the process of updating, and revising where appropriate, the air quality criteria document (AQCD) for ozone and related photochemical oxidants published in 1996. Under CAA sections 108 and 109, the purpose of the revised Ozone AQCD is to provide an assessment of the latest scientific information on the effects of ambient ozone on the public health and welfare, for use in EPA's current review of the NAAQS for ozone. In January 2005, EPA's National Center for Environmental Assessment, Research Triangle Park, NC (NCEA-RTP), within the Agency's Office of Research and Development (ORD), made available for public review and comment a First External Review Draft of a revised document, Air Quality Criteria for Ozone and Related Photochemical Oxidants (First External Review Draft), Volumes I, II, and III, (EPA/600/R-05/004aA, bA, and cA, first draft Ozone AQCD, January 2005). Detailed summary information on EPA's first draft Ozone AQCD is contained in a previous EPA Federal Register notice (70 FR 4850, January 31, 2005).

EPA is soliciting advice and recommendations from the CASAC by means of a peer review of the second draft Ozone AQCD. The CASAC, which is comprised of seven members appointed by the EPA Administrator, was established under section 109(d)(2) of the CAA (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 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 Ozone Review Panel complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies. This meeting is a continuation of the CASAC Ozone Review Panel's peer review of the current draft Ozone AQCD. The Panel met in a public meeting on May 4-5, 2005 to conduct its initial peer review of the first draft Ozone AQCD. The report from that meeting, dated June 22, 2005, is posted on the SAB Web site at:​sab/​pdf/​casac_​ozone_​casac-05-010.pdf.

In addition, pursuant to sections 108 and 109 of the CAA, EPA is in the process of reviewing the ozone NAAQS, which the Agency most recently revised in July 1997. EPA's Office of Air Quality Planning and Standards (OAQPS), within the Office of Air and Radiation (OAR), has developed a draft updated Staff Paper for ambient ozone as part of its review of the ozone NAAQS. This draft Ozone Staff Paper evaluates the policy implications of the key scientific and technical information contained in the current draft Ozone AQCD and identifies critical elements that EPA believes should be considered in its review of the ozone NAAQS. The Ozone Staff Paper is intended to “bridge the gap” between the scientific review contained in the Ozone AQCD and the public health and welfare policy judgments required of the EPA Administrator in reviewing the ozone NAAQS. EPA is soliciting early advice and recommendations from the CASAC by means of a consultation on the first draft Ozone Staff Paper and the first drafts of the Ozone Exposure Analysis and Risk Assessment.
