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 published the Integrated Review Plan for the Secondary National Ambient Air Quality Standards for Nitrogen Dioxide and Sulfur Dioxide (Final) in December 2007. The CASAC Panel provided a consultation on the draft Plan in October 2007: (http://yosemite.epa.gov/​sab/​sabproduct.nsf/​77B813F50BDD96C1852573A70005BAF3/​$File/​casac-08-003.pdf). EPA's Office of Research and Development (ORD) has completed the Draft Integrated Science Assessment for Oxides of Nitrogen and Sulfur—Environmental Criteria (ISA) and EPA's Office of Air and Radiation (OAR) will also release a Scope and Methods Plan for Risk/Exposure Assessment. The purpose of the April 2-3, 2008 meeting, is for the CASAC Panel to provide advice on these two documents. The chartered CASAC will meet by conference call to review and approve the Panel's draft report on the ISA.

Technical Contacts: Any questions concerning EPA's Draft Integrated Science Assessment for Oxides of Nitrogen and Sulfur—Environmental Criteria (First External Review Draft) should be directed to Dr. Tara Greaver, ORD, at [phone] or [e-mail]. Any questions concerning EPA's Scope and Methods Plan for Risk/Exposure Assessment: Secondary NAAQS Review for Oxides of Nitrogen and Oxides of Sulfur should be directed to Dr. Anne Rea, OAR, at [phone] or [e-mail].

Availability of Meeting Materials: EPA-ORD's Draft Integrated Science Assessment for Oxides of Nitrogen and Sulfur—Environmental Criteria (First External Review Draft) can be accessed at http://www.epa.gov/​ttn/​naaqs/​standards/​no2so2sec/​cr_​pd.html. EPA-OAR's Scope and Methods Plan for Risk/Exposure Assessment: Secondary NAAQS Review for Oxides of Nitrogen and Oxides of Sulfur will be accessible at http://www.epa.gov/​ttn/​naaqs/​standards/​no2so2sec/​cr_​pd.html.
