Background: The CASAC, which is comprised of seven members appointed by the EPA Administrator, was established under section 109(d)(2) of the Clean Air Act (CAA or 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 Ozone Review Panel, which consists of the members of the chartered CASAC supplemented by subject-matter-experts, complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

Under section 108 of the CAA, the Agency is required to establish National Ambient Air Quality Standards (NAAQS) for each of six pollutants for which EPA has issued criteria, including ambient ozone (O3). Section 109(d) of the Act subsequently requires periodic review and, if appropriate, revision of existing air quality criteria and NAAQS to reflect advances in scientific knowledge on the effects of the pollutant on public health and welfare. The Ozone Panel met in a public meeting in Durham, North Carolina on December 6-7, 2005, to conduct a peer review on EPA's 2nd draft Air Quality Criteria for Ozone and Related Photochemical Oxidants (August 2005). In a February 10, 2006, letter to the Administrator (EPA-CASAC-06-003), the CASAC indicated that it may need to provide additional advice related to chapter 8 of the AQCD which integrates human health effects and exposure. The CASAC's review of the 2nd draft is available on the SAB Web site at:​sab/​pdf/​oasac_​ozone_​casac-06-003.pdf.

On March 21, 2006, EPA's National Center for Environmental Assessment, Research Triangle Park (NCEA–RTP), released the Final O3 AQCD. Concomitantly, EPA's Office of Air Quality Planning and Standards (OAQPS) is completing work on a 2nd draft of A Review of the National Ambient Air Quality Standards for Ozone: Policy Assessment of Scientific and Technical Information. The latter document evaluates the policy implications of the scientific information in the Final O3 AQCD, and the results of the quantitative risk/exposure analysis. CASAC will hold a conference call to provide additional advice to the Agency as it works to complete the 2nd Draft NAAQS for O3.

Availability of Meeting Materials: The Final O3 AQCD can be accessed via the Agency's NCEA Web site at:​ncea/​cfm/​recordisplay.cfm?​deid=​149923. Any questions concerning the Final O3 AQCD should be directed to Dr. Mary Ross, NCEA-RTP, at phone: (919) 541-Start Printed Page 210275170, or e-mail: In addition, a copy of the draft agenda for this teleconference meeting will be posted on the SAB Web site at:​sab (under the “Agendas” subheading) in advance of this Ozone Panel meeting. Other meeting materials, including the discussion questions for the Ozone Panel, will be posted on the SAB Web site at:​sab/​panels/​casacorpanel.html prior to this teleconference.
