Members of the public wishing to provide comment should contact the DFO directly. Input from the public to the CASAC will have the most impact if it provides specific scientific, technical information or analysis or if it relates to the clarity or accuracy of the technical information for the CASAC's consideration. Members of the public can submit relevant comments for a federal advisory committee to consider pertaining to EPA's charge to the committee or review materials. Federal advisory committees and panels, including scientific advisory committees, provide independent advice to EPA. Therefore, the process for submitting comments to a federal advisory committee is different from the process used to submit comments to an EPA program office. Procedures for Providing Public Input: Public comment for consideration by EPA's federal advisory committees and panels has a different purpose from public comment provided to EPA program offices.

The CASAC and the CASAC Ozone Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies. Pursuant to FACA and EPA policy, notice is hereby given that the Chartered CASAC augmented with additional experts, known as the CASAC Ozone Review Panel, will hold a public teleconference to review and finalize its letters on the three EPA documents cited above. EPA's draft documents for CASAC review were prepared as part of the agency's review of the National Ambient Air Quality Standards (NAAQS) for ozone. The CASAC is a Federal Advisory Committee chartered under the Federal Advisory Committee Act (FACA), 5 U.S.C., App. The CASAC shall also provide advice, information, and recommendations to the Administrator on the scientific and technical aspects of issues related to the criteria for air quality standards, research related to air quality, sources of air pollution, and of adverse effects which may result from various strategies to attain and maintain air quality standards. 7409(d)(2), to review air quality criteria and NAAQS and recommend any new NAAQS and revisions of existing criteria and NAAQS as may be appropriate. The CASAC was established pursuant to the Clean Air Act (CAA) Amendments of 1977, codified at 42 U.S.C.
