# SUPPLEMENTARY INFORMATION:

*Background:*                     Pursuant to the Federal Advisory Committee Act, Public Law 92-463, 5 U.S.C., App. 2 (FACA), notice is hereby given that the CASAC Carbon Monoxide Panel will hold a public meeting to peer review two draft documents related to the NAAQS review for carbon monoxide and that the chartered CASAC will hold a public teleconference to review and approve the Panel's draft reports. 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 Panel and chartered CASAC 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 National Ambient Air Quality Standard (NAAQS) for the six “criteria” air pollutants, including carbon monoxide (CO). EPA is conducting scientific assessments to                           ( print page 54043)                        review the primary (health-based) NAAQS for CO. CASAC has previously provided consultative advice on EPA's                     *Plan for Review of the National Ambient Air Quality Standards for Carbon Monoxide,*                     the first document in this review of the CO NAAQS. CASAC held a public meeting on May 12-13, 2009 (as announced in 74 FR 15265-15266) in Chapel Hill, North Carolina to review the                     *Integrated Science Assessment for Carbon Monoxide (First External Review Draft)*                     and provide consultative advice on the                     *Carbon Monoxide National Ambient Air Quality Standards: Scope and Methods Plan for Risk*                     and                     *Exposure Assessment.*                     The CASAC advisory reports are available on the EPA Web site at                     *http://www.epa.gov/​casac*.                

                    The purpose of the November 16-17, 2009 meeting is for the CASAC Panel to conduct a peer review the                     *Integrated Science Assessment for Carbon Monoxide: Second External Review Draft*                     (September 2009) published by EPA's Office of Research and Development (ORD) and to review the                     *Risk and Exposure Assessment to Support the Review of the Carbon Monoxide Primary National Ambient Air Quality Standards—First External Review Draft (October 2009)*                     recently issued by EPA's Office of Air and Radiation (OAR). The chartered CASAC will review and approve the Panel's draft reports by a public conference call on December 22, 2009.
