Draft Toxicological Review of Biphenyl: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA)

ACTION: Notice of Public Comment Period and Listening Session

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

SUMMARY: EPA is announcing a 60-day public comment period and a public 
listening session for the external review draft human health assessment 
titled, ``Toxicological Review of Biphenyl: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)'' (EPA/
635/R-11/005C). The draft assessment was prepared by the National 
Center for Environmental Assessment (NCEA) within the EPA Office of 
Research and Development (ORD). EPA is releasing this draft assessment 
solely for the purpose of pre-dissemination peer review under 
applicable information quality guidelines. This draft assessment has 
not been formally disseminated by EPA. It does not represent and should 
not be construed to represent any Agency policy or determination. After 
public review and comment, an EPA contractor will convene an expert 
panel for independent external peer review of this draft assessment. 
The public comment period and external peer review meeting are separate 
processes that provide opportunities for all interested parties to 
comment on the assessment. The external peer review meeting will be 
scheduled at a later date and announced in the Federal Register. Public 
comments submitted during the public comment period will be provided to 
the external peer reviewers before the panel meeting and considered by 
EPA in the disposition of public comments. Public comments received 
after the public comment period closes will not be submitted to the 
external peer reviewers and will only be considered by EPA if time 
permits.
    The listening session will be held on Wednesday, November 16, 2011, 
during the public comment period for this draft assessment. The purpose 
of the listening session is to allow all interested parties to present 
scientific and technical comments on draft IRIS health assessments to 
EPA and other interested parties attending the listening session. EPA 
welcomes the comments that will be provided to the Agency by the 
listening session participants. The comments will be considered by the 
Agency as it revises the draft assessment after the independent 
external peer review. If listening session participants would like EPA 
to share their comments with the external peer reviewers, they should 
also submit written comments during the public comment period using the 
detailed and established procedures described in the SUPPLEMENTARY 
INFORMATION section of this notice.

DATES: The public comment period begins September 30, 2011, and ends 
November 29, 2011. Comments should be in writing and must be received 
by EPA by November 29, 2011.
    The listening session on the draft assessment for biphenyl will be 
held on Wednesday, November 16, 2011, beginning at 9 a.m. and ending at 
4 p.m., Eastern Standard Time, or when all presentations have been 
completed. To attend the listening session, interested parties should 
register no later than Wednesday, November 9, 2011. To present at the 
listening session, indicate in your registration that you would like to 
make oral comments at the session and provide the length of your 
presentation. The following are instructions for registering: To attend 
the listening session, register by contacting Ms. Bethzaida Colon of 
Versar, Inc. via e-mail at bcolon@versar.com (subject line: Biphenyl

please indicate if you will need audio-visual equipment (e.g., laptop

presentations than the allotted time allows, then the time limit for 
each presentation will be adjusted. A copy of the agenda for the 
listening session will be available at the meeting. If no speakers have 
registered by Wednesday, November 9, 2011, the listening session will 
be cancelled, and EPA will notify those registered of the cancellation.

SUPPLEMENTARY INFORMATION:

I. Information About IRIS

    EPA's IRIS is a human health assessment program that evaluates 
quantitative and qualitative risk information on effects that may 
result from exposure to chemical substances found in the environment. 
Through the IRIS Program, EPA provides the highest quality science-
based human health assessments to support the Agency's regulatory 
activities. The IRIS database contains information for more than 540 
chemical substances that can be used to support the first two steps 
(hazard identification and dose-response evaluation) of the risk 
assessment process. When supported by available data, IRIS provides 
oral reference doses (RfDs) and inhalation reference concentrations 
(RfCs) for chronic noncancer health effects and cancer assessments. 
Combined with specific exposure information, government and private 
entities use IRIS to help characterize public health risks of chemical 
substances in a site-specific situation and thereby support risk 
management decisions designed to protect public health.
