Science Advisory Board Staff Office; Clean Air Scientific 
Advisory Committee (CASAC); Notification of Advisory Meeting of the 
CASAC Ambient Air Monitoring and Methods (AAMM) Subcommittee

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.


SUMMARY: The Environmental Protection Agency Science Advisory Board 
(SAB) Staff Office announces a public meeting of the Clean Air 
Scientific Advisory Committee's (CASAC) Ambient Air Monitoring and 
Methods (AAMM) Subcommittee to conduct a peer review on the Federal 
Reference Method (FRM) for thoracic coarse particulate matter 
(PM10-2.5) and a consultation on various PM monitoring-
related issues.

DATES: The meeting will be held Wednesday, September 21, 2005, from 9 
a.m. to 5:30 p.m. (eastern time), and Thursday, September 22, 2005, 
from 8:30 a.m. to 3 p.m. (eastern time).

ADDRESSES: The meeting will take place at the Marriott Durham Civic 
Center Hotel, 210 Foster Street, Durham, NC 27701.

FOR FURTHER INFORMATION CONTACT: Any member of the public who would 
like to submit written or brief oral comments (5 minutes or less), or 
wants further information concerning this meeting, should contact Mr. 
Fred Butterfield, Designated Federal Officer (DFO), EPA Science 
Advisory Board (1400F), U.S. Environmental Protection Agency, 1200 
Pennsylvania Avenue, NW., Washington, DC 20460; via telephone/voice 
mail: (202) 343-9994; fax: (202) 233-0643; or e-mail at: 
butterfield.fred@epa.gov. General information concerning the CASAC or 
the EPA Science Advisory Board can be found on the EPA Web site at: 

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 Subcommittee complies with the provisions of FACA and all 
appropriate SAB Staff Office procedural policies.
    Background: Under section 108 of the CAA, the Agency is required to 
establish NAAQS for each pollutant for which EPA has issued criteria, 
including particulate matter (PM). Section 109(d) of the Act 
subsequently requires periodic review and, if appropriate, revision of 
existing air quality criteria to reflect advances in scientific 
knowledge on the effects of the pollutant on public health and welfare. 
The Agency is also to revise the NAAQS, if appropriate, based on the 
revised criteria.
    EPA is currently reviewing the NAAQS for PM. As part of this 
review, the Agency is considering potential NAAQS for thoracic coarse 
particulate matter (PM10-2.5). Further information on EPA's 
ongoing PM NAAQS review is available at the following URL: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.html.
    In conjunction with the review of the PM NAAQS, EPA is evaluating 
potential monitoring methods for measurement of PM10-2.5. 
The Agency's Office of Air Quality Planning and Standards (OAQPS), 
within EPA's Office of Air and Radiation (OAR), has requested that the 
CASAC conduct a peer review of the Federal Reference Method (FRM) for 
PM10-2.5 to provide independent scientific advice on the 
appropriateness of this method for being the basis of comparison in 
approving coarse-particle continuous monitors. The FRM for 
PM10-2.5 will establish the basis for approval of 
continuous-monitoring methods in a performance-based measurement system 
process. In addition, OAQPS has asked the CASAC to conduct a 
consultation to the Agency on: Fine particle (PM2.5) FRM 
optimization and equivalency criteria for continuous monitors; and 
PM10-2.5 methods evaluation, network data quality objectives 
(DQOs), and equivalency criteria for continuous monitors. The CASAC 
AAMM Subcommittee provided advice and recommendations for this ongoing 
work at a July 22, 2004 consultative meeting on PM10-2.5 
methods and DQOs.
