# 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 assessments to determine both primary (health-based) and secondary (welfare-based) standards for each of these pollutants. As part of that process, EPA's Office of Research and Development (ORD) has released the                     *Integrated Science Assessment for Particulate Matter*                     (Second External Review Draft, July 2009) for review by CASAC at the October 5-6, 2009 meeting. EPA's Office of Air and Radiation (OAR) will release two additional documents for CASAC review and public comment entitled                     *Risk Assessment to Support the Review of the PM Primary National Ambient Air Quality Standards: External Review Draft*                     (September 2009) and                     *Particulate Matter Urban-Focused Visibility Assessment: External Review Draft*                     (September 2009) on or about September 4, 2009. The purpose of the October 5-6, 2009 meeting is to review these three documents. In addition, this meeting will also include a discussion with CASAC of an EPA/OAR document entitled                     *Policy Assessment for the Review of the Particulate Matter National Ambient Air Quality Standards: Preliminary Draft*                     (September 2009) on the nature of the policy assessment document including the overall structure, areas of focus, and level of detail. The EPA plans to release this preliminary draft document on or about September 15, 2009. If additional time is needed to complete the agenda after the October 5-6, 2009 face-to-face meeting, a public teleconference will be held on October 7, 2009 from 2 p.m.-5 p.m. (Eastern Time). To review and approve CASAC's draft letters on the three review documents, a public teleconference will be held on November 12, 2009 from 10 a.m.-12 p.m. (Eastern Time).                

                    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 advise on                     *Particulate Matter National Ambient Air Quality Standards: Scope and Methods Plan for Health Risk*                     (February 2009) and                     *Exposure Assessment*                     and                     *Particulate Matter National Ambient*

*Air Quality Standards: Scope and Methods Plan for Urban Visibility Impact Assessment*                     (February 2009). The April 12, 2009 meeting was announced February 19, 2009 in 74 FR 7688-7689.
