SUPPLEMENTARY INFORMATION:

Background: The Clean Air Scientific Advisory Committee (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 is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C. App. The 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 includes, but is 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. As part of that process, EPA's Office of Research and Development (ORD) issued the Draft Integrated Science Assessment fox Oxides of Nitrogen and Sulfur—Environmental Criteria (ISA) in December 2007 and recently issued the second draft ISA in August 2008. EPA's Office of Air and Radiation (OAR) released its Scope and Methods Plan for Risk/Exposure Assessment (REA) in March 2008. OAR completed the first draft REA in August 2008. The CASAC reviewed the first draft ISA and provided consultative advice on the Scope and Methods plan on April 1-2, 2008. The CASAC's reports to the Administrator can be found on the SAB Web site at http://www.epa.gov/​casac (see EPA-CASAC-08-011 and EPA-CASAC-08-012 both dated May 19, 2008).

The purpose of the October 1-2, 2008 meeting is for the CASAC Panel to conduct a peer review of the second draft ISA and the first draft REA. The chartered CASAC will review and approve the Panel's draft reports on the ISA and REA by public conference call on October 30, 2008.
