Background: Under section 108 of the Clean Air Act (CAA or Act), the Agency is required to establish National Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA has issued criteria, including ozone (O3). Section 109(d) of the CAA subsequently requires periodic review and, if appropriate, revision of existing air quality criteria and standards to reflect advances in scientific knowledge on the effects of the pollutant on public health and welfare. The Agency revised the NAAQS for O3 in July 1997. EPA's Office of Research and Development (ORD) has recently released a draft updated air quality criteria document for O3 (draft Ozone AQCD). The CASAC Ozone Review Panel will convene to conduct a peer review on this draft Ozone AQCD on May 4-5, 2005. EPA's Office of Air Quality Planning and Standards (OAQPS), within the Office of Air and Radiation (OAR), is in the process of developing a draft updated Staff Paper for O3 as part of its review of the O3 NAAQS. This draft Staff Paper will evaluate the policy implications of the key scientific and technical information contained in the draft Ozone AQCD and identify critical elements that EPA believes should be considered in the review of the O3 NAAQS. The O3 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 O3 NAAQS. Key components of this O3 Staff Paper include a quantitative population exposure analysis and health risk assessment. OAQPS has developed a draft Ozone Health Assessment Plan which includes a discussion of the scope, approaches, and methods that staff is planning to use in conducting the population exposure analysis and health risk assessment.

EPA is soliciting advice and recommendations from the CASAC by means of a consultation on the draft Ozone Health Assessment Plan. 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 will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.
