SUMMARY: The EPA Science Advisory Board (SAB) Staff Office announces 
two public meetings of the SAB Polycyclic Aromatic Hydrocarbon (PAH)

Mixtures, External Review Draft.

DATES: There will be a public teleconference on June 8, 2010 from 2 
p.m. to 4 p.m. (Eastern Time). The public meeting will be held on June 
21, 2010 from 9 a.m. to 5 p.m. (Eastern Time), June 22, 2010 from 9

FOR FURTHER INFORMATION CONTACT: Any member of the public wishing to 
obtain information concerning the public teleconference and/or public 
meeting may contact Mr. Aaron Yeow, Designated Federal Officer (DFO), 
EPA Science Advisory Board Staff Office (1400F), U.S. Environmental 
Protection Agency, 1200 Pennsylvania Avenue, NW., Washington, DC 20460; 
by telephone/voice mail at (202) 343-9878 or at [email protected]. 
General information about the SAB, as well as any updates concerning

at http://www.epa.gov/sab.

SUPPLEMENTARY INFORMATION: Pursuant to the Federal Advisory Committee 
Act (FACA), 5 U.S.C., App. 2, notice is hereby given that the SAB PAH 
Mixtures Review Panel will hold a public teleconference to discuss the 
plans for the subsequent public face-to-face meeting to conduct a peer 
review of the EPA's draft technical document, Development of a Relative 
Potency Factor (RPF) Approach for Polycyclic Aromatic Hydrocarbon (PAH) 
Mixtures, External Review Draft (February 2010). The SAB was 
established pursuant to 42 U.S.C. 4365 to provide independent 
scientific and technical advice to the Administrator on the technical 
basis for Agency positions and regulations.
    The SAB is a Federal Advisory Committee chartered under FACA. The 
SAB will comply with the provisions of FACA and all appropriate SAB 
Staff Office procedural policies.
    Background: EPA's Integrated Risk Information System (IRIS) is an 
electronic database containing descriptive and quantitative 
toxicological information on human health effects that may result from 
chronic exposure to various substances in the environment. This 
information supports human health risk assessments and includes hazard 
identification and dose-response data and derivations of oral reference 
doses (RfDs) and inhalation reference concentrations (RfCs) for 
noncancer effects and oral slope factors and oral and inhalation unit 
risks for cancer effects. IRIS is prepared and maintained by EPA's 
National Center for Environmental Assessment (NCEA) within the Office 
of Research and Development (ORD). NCEA's IRIS Program has developed a 
draft technical document entitled, Development of a Relative Potency 
Factor (RPF) Approach for Polycyclic Aromatic Hydrocarbon (PAH) 
Mixtures, for estimating cancer risk from exposure to PAH mixtures. ORD 
has requested that the Science Advisory Board (SAB) conduct a review of 
this draft document.
    In response to ORD's request, the SAB Staff Office solicited 
nominations of experts and formed a review panel for PAH Mixtures 
[Federal Register Notice dated October 21, 2009 (74 FR 54047-54048)]. 
The panel will conduct a review of EPA's February 2010 External Review 
Draft of its technical document, Development of a Relative Potency 
Factor (RPF) Approach for Polycyclic Aromatic Hydrocarbon (PAH) 
Mixtures. Specifically, the panel is being asked to provide 
recommendations on the rationale for recommending an RPF approach, the 
evaluation of the carcinogenicity of individual PAHs, the methods for 
dose response assessment

[[Page 27778]]

and RPF calculation, the selection of PAHs to include in the RPF 
approach, the derivation of RPFs for selected PAHs, and the 
uncertainties and limitations associated with the RPF approach. The 
purpose of the teleconference is for the panel to receive a briefing on 
the draft technical document and for members to clarify the charge to 
the panel. During the face-to-face meeting, the panel will review the 
technical document.
    Availability of Meeting Materials: Agendas and materials in support 
of these meetings will be placed on the EPA Web site at http://www.epa.gov/sab in advance of each meeting. For technical questions and 
information concerning EPA's draft document, please contact Dr. Lynn 
Flowers at (703) 347-8537, or [email protected].
    Procedures for Providing Public Input: Public comment for 
consideration by EPA's federal advisory committees and panels has a 
different purpose from public comment provided to EPA program offices. 
Therefore, the process for submitting comments to a federal advisory 
committee is different from the process used to submit comments to an 
EPA program office.
    Federal advisory committees and panels, including scientific 
advisory committees, provide independent advice to EPA. Members of the 
public can submit comments for a federal advisory committee to consider 
as it develops advice for EPA. They should send their comments directly 
to the Designated Federal Officer for the relevant advisory committee. 
Oral Statements: In general, individuals or groups requesting an oral 
presentation at a public teleconference will be limited to three 
minutes per speaker, with no more than a total of 30 minutes for all 
speakers. At the face-to-face meeting, presentations will be limited to 
five minutes, with no more than a total of one hour for all speakers. 
Each person making an oral statement should consider providing written 
comments as well as their oral statement so that the points presented 
orally can be expanded upon in writing. Interested parties should 
contact Mr. Aaron Yeow, DFO, in writing (preferably via e-mail) at the 
contact information noted above by June 1, 2010 for the teleconference 
and by June 14, 2010 for the face-to-face meeting, to be placed on the 
list of public speakers. Written Statements: Written statements should 
be supplied to the DFO via email at the contact information noted above 
by June 1, 2010 for the teleconference and by June 14, 2010 for the 
face-to-face meeting so that the information may be made available to 
the Committee members for their consideration. Written statements 
should be supplied in one of the following electronic formats: Adobe 
Acrobat PDF, MS Word, MS PowerPoint, or Rich Text files in IBM-PC/
Windows 98/2000/XP format. Submitters are requested to provide versions 
of signed documents, 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 Mr. Aaron Yeow at (202) 
343-9878 or [email protected]. To request accommodation of a 
disability, please contact Mr. Yeow preferably at least ten days prior 
to each meeting to give EPA as much time as possible to process your 
request.

    Dated: May 12, 2010.
Anthony F. Maciorowski,
Deputy Director, EPA Science Advisory Staff Office.
