# SUPPLEMENTARY INFORMATION:

## CASAC and the AAMM Subcommittee 

The CASAC, which comprises seven members appointed by the EPA Administrator, 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, in part to provide advice, information and recommendations on the scientific and technical aspects of issues related to air quality criteria and national ambient air quality standards (NAAQS) under sections 108 and 109 of the Act. The CASAC, which is administratively located under the SAB Staff Office, is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. 

The SAB Staff Office established the CASAC AAMM Subcommittee in early 2004 as a standing subcommittee to provide the EPA Administrator, through the CASAC, with advice and recommendations, as necessary, on topical areas related to ambient air monitoring, methods and networks. The Committee and the Subcommittee comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies. 

## Background 

                    In response to a request from EPA's Office of Air and Radiation (OAR), Office of Air Quality Planning and Standards (OAQPS), the CASAC AAMM Subcommittee conducted a peer review on the FRM for PM10-2.5                     and a consultation on various particulate matter (PM) monitoring-related issues at a public meeting held September 21-22, 2005 in Durham, NC. Subsequent to that meeting, the Subcommittee drafted an advisory report for the CASAC's consideration. Detailed summary information on EPA's proposed FRM for thoracic coarse particulate matter is contained in a previous                     **Federal Register**                     notice (70 FR 51353, August 30, 2005).
