ENVIRONMENTAL PROTECTION AGENCY

[FRL-8683-7]


Science Advisory Board Staff Office; EPA Clean Air Scientific 
Advisory Committee (CASAC); Notification of Public Advisory Committee 
Meetings (Teleconferences) of the CASAC Ambient Air Monitoring & 
Methods (AAMM) Subcommittee and the CASAC

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA or Agency) 
ScienceAdvisory Board (SAB) Staff Office announces: A public advisory 
teleconference of the Ambient Air Monitoring & Methods (AAMM) 
Subcommittee (Subcommittee) of the Clean Air Scientific Advisory 
Committee (CASAC) to conduct a peer review of the proposed Federal 
Reference Method (FRM) for the measurement of lead (Pb) in particulate 
matter less than 10 micrometers in diameter (PM10) in 
ambient air, and a consultation concerning the need and approaches for 
the development of a low-volume ambient air monitor for Pb in total 
suspended particulate (TSP) FRM or Federal Equivalent Method (FEM); and 
a public teleconference of the chartered CASAC to review and approve 
the Subcommittee's report from its review of the Pb-PM10 
FRM.

DATES: The Subcommittee will hold a public teleconference on Monday, 
July 14, 2008, from 1 p.m. to 5 p.m. (Eastern Time). The chartered 
CASAC will hold a public teleconference on Monday, August 18, 2008, 
from 1 p.m. to 4 p.m. (Eastern Time).

FOR FURTHER INFORMATION CONTACT: Any member of the public who wishes to 
obtain the teleconference call-in numbers and access codes; submit a 
written or brief oral statement (three minutes or less); or receive 
further information concerning these teleconference meetings, must 
contact Mr. Fred Butterfield, Designated Federal Officer (DFO). Mr. 
Butterfield may be contacted at the EPA Science Advisory Board (1400F), 
U.S. Environmental Protection Agency, 1200 Pennsylvania Avenue, NW., 
Washington, DC 20460; or via telephone/voice mail: 202-343-9994; fax: 
202-233-0643; or e-mail at [email protected]. General 
information concerning the CASAC can be found on the EPA Web site at 
http://www.epa.gov/casac.

SUPPLEMENTARY INFORMATION:
    Background: The CASAC, which is composed of 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. The CASAC provides advice, information 
and recommendations on the scientific and technical aspects of issues 
related to air quality criteria and the National Ambient Air Quality 
Standards (NAAQS) under sections 108 and 109 of the Act. The CASAC is 
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 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 CASAC and the Subcommittee comply with the provisions 
of FACA and all appropriate SAB Staff Office procedural policies.

[[Page 35387]]

    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 lead. EPA 
initiated its current review of the NAAQS for lead in early 2005. In 
March 2008, the Subcommittee held a public teleconference meeting to 
conduct a consultation on technical issues relating to the ambient air 
monitoring of Pb-PM10, including options for the Lead NAAQS 
indicator, a draft Federal Reference Method (FRM) for Pb-
PM10, lead monitoring network design, and sampling 
frequency. The CASAC's report to the EPA Administrator concerning this 
consultation (EPA-CASAC-08-010, dated April 14, 2008) is available on 
the EPA Web site at http://yosemite.epa.gov/sab/sabproduct.nsf/
733B01113F8000AA8525742C005C478D/$File/EPA-CASAC-08-010-unsigned.pdf.
    On May 20, 2008, EPA published in the Federal Register (FR 73 
29184) its proposed rule for the revision of the NAAQS for Lead and 
associate lead-monitoring requirements. The proposed revisions included 
a proposed FRM for the measurement of Pb-PM10. In addition, 
the preamble requested public comments on the need and approaches for 
the development of a low-volume ambient air monitor for Pb in total 
suspended particulate (TSP) FRM or Federal Equivalent Method (FEM). The 
purpose of the July 14, 2008 public teleconference is for the 
Subcommittee to conduct a technical peer review on the proposed FRM for 
Pb-PM10 and to provide a consultation on the need for and 
approaches for development of a low-volume Pb-TSP FRM or FEM. The 
purpose of the August 18, 2008 public teleconference is for the 
chartered CASAC to review and approve the Subcommittee's draft report 
from its review of the Pb-PM10 FRM.
    Technical Contacts: Any technical questions concerning the Agency's 
proposed FRM can be directed to Mr. Kevin Cavender, OAQPS, at phone: 
919-541-2364, or e-mail [email protected]; or to Mr. Lewis 
Weinstock, OAQPS, at phone: 919-541-3661, or e-mail 
[email protected].
    Availability of Meeting Materials: The draft FRM for Pb-
PM10 that will be the subject of the peer review is 
contained in the Federal Register notice for the proposed rule (May 20, 
2008, FR 73 29184). The Agency will post additional documents to be 
discussed during this consultation on the EPA Technology Transfer 
Network (TTN) Web page for the Lead NAAQS at http://www.epa.gov/ttn/naaqs/standards/pb/s_pb_cr_td.html. The meeting agenda and any other 
materials for the CASAC teleconferences will be posted on the EPA Web 
site at http://www.epa.gov/casac in advance of these teleconferences.
