*Background:*                     Pursuant to the Federal Advisory Committee Act, Public Law 92-463 5 U.S.C., App. 2 (FACA), notice is hereby given that a CASAC Panel will hold a public meeting to peer review EPA's                     *Risk and Exposure Assessment for Review of the Secondary National Ambient Air Quality Standards for Oxides of Nitrogen and Oxides of Sulfur: Second Draft*                     and that the chartered CASAC will hold a public teleconference to review and approve the Panel's draft report. The CASAC 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. CASAC provides advice, information and recommendations on the scientific and technical aspects of air quality criteria and national ambient air quality standards (NAAQS) under sections 108 and 109 of the Act. The CASAC and CASAC Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.                

                    Section 109(d)(1) of the CAA requires that the Agency periodically review and revise, as appropriate, the air quality criteria and the NAAQS for the six “criteria” air pollutants, including NOx                     and SOx                    . EPA is in the process of reviewing the secondary NAAQS for NOx                     and SOx. Welfare effects as defined in the CAA include, but are not limited to, effects on soils, water, wildlife, vegetation, visibility, weather, and climate, as well as effects on materials, economic values, and personal comfort and well-being.
