[FRL-9106-8]


Science Advisory Board Staff Office; Notification of a Clean Air 
Scientific Advisory Committee (CASAC); Ambient Air Methods and 
Monitoring Subcommittee (AAMMS); Meeting and Public Teleconference

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Environmental Protection Agency (EPA or Agency) Science 
Advisory Board (SAB) Staff Office is announcing a public meeting of the 
Clean Air Scientific Advisory Committee (CASAC) Ambient Air Monitoring 
& Methods Subcommittee (AAMMS or Subcommittee) to provide advice 
concerning ambient air monitoring issues for the Particulate Matter 
(PM) National Ambient Air Quality Standards (NAAQS) related to urban 
visibility. The chartered CASAC will subsequently hold a public 
teleconference to review and approve the Subcommittee's report.

DATES: The CASAC AAMMS meeting will be held on Tuesday, February 24, 
2010 from 9 a.m. to 5:30 p.m. (Eastern Time) and Wednesday, February 
25, 2010 from 8 a.m. to 2 p.m. (Eastern Time). The public

(Eastern Time).

ADDRESSES: The public meeting will be held at the SAB Conference Center 
at 1025 F Street, NW., Suite 3700, Washington, DC 20004.

FOR FURTHER INFORMATION CONTACT: Any member of the public who wishes to 
submit a written or brief oral statement or wants further information 
concerning the February 24-25, 2010 meeting may contact Ms. Kyndall 
Barry, 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-
9868; fax (202) 233-0643; or e-mail at [email protected]. For

at [email protected]. General information concerning the CASAC 
and the CASAC documents can be found on the EPA Web site at http://www.epa.gov/casac.

SUPPLEMENTARY INFORMATION: Background: Pursuant to the Federal Advisory 
Committee Act, Public Law 92-463 5 U.S.C., App. 2 (FACA), notice is 
hereby given that the CASAC AAMMS will hold a public meeting to provide 
advice on monitoring issues related PM urban visibility and that the 
chartered CASAC will hold a public teleconference to review and approve 
the Subcommittee's draft report. 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 Panel and chartered CASAC

[[Page 4070]]

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 
NAAQS for the six ``criteria'' air pollutants, including particulate 
matter. The EPA Office of Air and Radiation requested AAMMS advice on 
monitoring issues related to urban visibility. In October 2006, EPA 
issued the final rule to revise both the primary and secondary NAAQS 
for PM (71 FR 61144) and retain PM10 as the indicator for 
thoracic coarse particles. The secondary standards for PM2.5 
and PM10 were set identical to the respective primary 
standards to address PM-related welfare effects including visibility 
impairment, effects on vegetation and ecosystems, materials damage and 
soiling, and effects on climate change. The Agency is considering 
development of a specific indicator for urban visibility in support of 
a future secondary NAAQS. CASAC has been asked to provide advice on 
proposed options for an urban visibility indicator, and any methods and 
equipment for its direct measurement. The Agency is also seeking advice 
from AAMMS on options for a potential pilot monitoring network and/or a 
nationwide enforcement network for PM welfare effects. The chartered 
CASAC will hold a public teleconference to review the AAMMS draft 
report on March 26, 2010.
    Technical Contacts: Any technical questions concerning the 
indicator and ambient air monitoring issues related to the PM NAAQS can 
be directed to Mr. Tim Hanley, OAQPS, at [email protected] or (919) 
541-4417.
    Availability of Meeting Materials: The Agency document, PM Light 
Extinction Measurements for a Possible Secondary PM NAAQS, will be 
posted on the EPA Technology Transfer Network Web site on the 
respective page for Ambient Monitoring Technology Information Center at 
http://www.epa.gov/ttn/amtic/casacinf.html. Prior to the meetings, the 
agendas and other materials for these CASAC meetings will be accessible 
through the calendar link on the blue navigation bar at http://www.epa.gov/casac/.
    Procedures for Providing Public Input: Interested members of the 
public may submit relevant written or oral information for 
consideration on the topics included in this advisory activity. Oral 
Statements: To be placed on the public speaker list for the
    February 24-25, 2010 meeting, interested parties should notify Ms.

placed on the public speaker list for the March 26, 2010 
teleconference, interested parties should notify Dr. Holly Stallworth, 
DFO, by e-mail no later than March 15, 2010. Individuals making oral 
statements will be limited to five minutes per speaker. Written 
Statements: Written statements for the February 24-25, 2010 meeting 
should be received in the SAB Staff Office by
    February 12, 2010, so that the information may be made available to 
the CASAC Panel for its consideration prior to this meeting. Written

Staff Office by March 12, 2010. Written statements should be supplied

Text files in IBM-PC/Windows 98/2000/XP format). Submitters are asked 
to provide versions of each document submitted with and without 
signatures, because the SAB Staff Office does not publish documents 
with signatures on its Web sites.
    Accessibility: For information on access or services for 
individuals with disabilities, please contact Ms. Barry at the phone 
number or e-mail address noted above, preferably at least ten days
