# 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 CASAC will comply with the provisions of FACA and all appropriate SAB Staff Office procedures.                  

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 particulate matter (PM). EPA conducts scientific assessments to determine both primary (health-based) and secondary (welfare-based) standards for each of these pollutants.

                    The CASAC PM Review Panel will hold a public teleconference on May 7, 2009 to review and approve draft letters reviewing three EPA draft documents supporting EPA's review of the PM National Ambient Air Quality Standard: (1)                     *Integrated Science Assessment for Particulate Matter—First External Review Draft, Dec 2008;*                     (2)                     *PM**NAAQS: Scope and Methods Plan for Health Risk and Exposure Assessment (February 2009);*                     and (3)                     *PM NAAQS: Scope and Methods Plan for Urban Visibility Impact Assessment (February 2009).*

                    The CASAC PM Panel previously held a public meeting on April 1-2, 2009 (announced in 74 FR 7688-7689) to review these documents. The purpose of the May 7, 2009 teleconference is to                           ( print page 18231)                        review and approve the CASAC PM Panel's draft letters on the above-referenced documents.                

                    Additional information about the CASAC PM panel's review and advice in support of EPA's NAAQS review for PM can be found on the CASAC Web site at                     *http://yosemite.epa.gov/​sab/​sabproduct.nsf/​WebProjectsbyTopicCASAC!OpenView.*
