# 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 2. 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 National Ambient Air Quality Standard (NAAQS) for the six “criteria” air pollutants, including particulate matter (PM). EPA conducts scientific and policy assessments related to both primary (health-based) and secondary (welfare-based) standards for each of these pollutants. As part of that process, the CASAC Particulate Matter Review Panel reviews a series of EPA's assessments that provide the basis for EPA rulemaking.

                    The purpose of the March 10-11, 2010 meeting is to review second drafts of the                     *Particulate Matter Urban-Focused Visibility Assessment*                     (January 2010) and                     *Quantitative Health**Risk Assessment for Particulate Matter*                     (February 2010). In addition the March 10-11, 2010 meeting will also include a presentation on a first draft of EPA's                     *Policy Assessment for the Review of the Particulate Matter National Ambient Air Quality Standards*                     (                    *Policy Assessment,*                     February 2010). The                     *Policy Assessment*                     will serve to “bridge the gap” between the scientific information and the judgments required of the Administrator in determining whether it is appropriate to retain or revise the standards. The first draft                     *Policy Assessment*                     builds upon the key scientific and technical information contained in the Agency's                     *Integrated Science Assessment for Particulate Matter*                     (Final Report) (ISA, December 2009) as well as the two draft assessment documents titled                     *Particulate Matter Urban-Focused Visibility Assessment: Second External Review Draft*                     (January 2010) and                     *Quantitative Health Risk Assessment for Particulate Matter: Second External Review Draft*                     (February 2010). CASAC's deliberations on the first draft                     *Policy Assessment*                     will take place during the teleconference scheduled for April 8, 2010 and if more time is needed, on April 9, 2010.                

                    Background information about the formation of the CASAC Particulate Matter Review Panel was published in the                     **Federal Register**                     on March 8, 2007 (72 FR 10527-10528). The Panel previously held a public teleconference on November 30, 2007 (announced in 72 FR 63177-63178) to provide consultative advice on EPA's draft                     *Integrated Review Plan for the National Ambient Air Quality Standards for Particulate Matter*                     (October 2007) the first document in this review of the PM NAAQS. On April 1-2, 2009, CASAC reviewed the                     *Integrated Science Assessment for Particulate Matter—First External Review Draft*                     (December 2008), and provided consultative advice on                     *Particulate Matter National Ambient Air Quality Standards: Scope and Methods Plan for Health Risk and Exposure Assessment*                     (February 2009) and                     *Particulate Matter National Ambient Air Quality Standards: Scope and Methods Plan for Urban Visibility Impact Assessment*                     (February 2009). The April 1-2, 2009 meeting was announced February 19, 2009 in 74 FR 7688-7689. As announced in 74 FR 46586—46587, on October 5-6, 2009, CASAC reviewed the                     *Integrated Science Assessment for Particulate Matter—Second External Review Draft*                     (July 2009) and                     *Particulate Matter Urban Focused Visibility Assessment-External Review Draft*                     (September 2009) and                     *Risk Assessment to Support the Review of the PM Primary National Ambient Air Quality Standards-External Review Draft*                     (September 2009).
