Science Advisory Board Staff Office; Notification of a Public 
Teleconference of the Science Advisory Board; Polycyclic Aromatic 
Hydrocarbon (PAH) Mixtures Review Panel

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.


SUMMARY: The EPA Science Advisory Board (SAB) Staff Office announces a 
public teleconference of the SAB Polycyclic Aromatic Hydrocarbon (PAH) 
Mixtures Review Panel to discuss its draft report on EPA's Development 
of a Relative Potency Factor (RPF) Approach for Polycyclic Aromatic 
Hydrocarbon (PAH) Mixtures.

DATES: The SAB PAH Mixtures Review Panel will conduct a public 
teleconference on September 30, 2010. The teleconference will begin at 
1 p.m. and end at 5 p.m. (Eastern Time).

ADDRESSES: The teleconference will be conducted by telephone only.

FOR FURTHER INFORMATION CONTACT: Any member of the public wishing to 
obtain general information concerning the public teleconference may 
contact Mr. Aaron Yeow, Designated Federal Officer (DFO), via telephone 
at (202) 564-2050 or e-mail at [email protected]. General information 
concerning the EPA Science Advisory Board can be found on the EPA Web 
site at http://www.epa.gov/sab.

SUPPLEMENTARY INFORMATION: Pursuant to the Federal Advisory Committee 
Act, 5 U.S.C., App. 2 (FACA), notice is hereby given that the SAB PAH 
Mixtures Review Panel will hold a public teleconference to discuss its 
draft report on EPA's Development of a Relative Potency Factor (RPF) 
Approach for Polycyclic Aromatic Hydrocarbon (PAH) Mixtures. 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 
    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.
    The SAB PAH Mixtures Review Panel held a public teleconference on 
June 8, 2010 and a public meeting on June 21-23, 2010 to review EPA's 
Development of a Relative Potency Factor (RPF) Approach for Polycyclic 
Aromatic Hydrocarbon (PAH) Mixtures [see Federal Register notice dated 
May 18, 2010 (75 FR 27777-27778)]. Materials from the June 8, 2010 
teleconference and June 21-23, 2010 meeting are posted on the SAB Web 
site at http://yosemite.epa.gov/sab/sabproduct.nsf/fedrgstr_activites/Human%20Health%20PAH%20Mixtures?OpenDocument.
    The purpose of the upcoming teleconference is for the PAH Mixtures 
Review Panel to discuss its draft report. The Panel's draft report will 
be submitted to the chartered SAB for their consideration and approval. 
A meeting agenda and the draft SAB review report will be posted at the 
above noted SAB Web site prior to the meeting.
    Availability of Meeting Materials: Agendas and materials in support 
of the

teleconference will be placed on the SAB Web site at http://www.epa.gov/sab in advance of the teleconference. 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. 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 September 23, 2010 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 September 23, 2010 so that the information 
may be made available to the Panel 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) 
564-2050 or [email protected]. To request accommodation of a 
disability, please contact Mr. Yeow preferably at least ten days prior 
to the teleconference to give EPA as much time as possible to process 
your request.

    Dated: August 31, 2010.
Anthony Maciorowski,
 Deputy Director, EPA Science Advisory Staff Office.
