Draft Toxicological Reviews of Polybrominated Diphenyl Ethers 
(PBDEs): In support of the Summary Information in the Integrated Risk 
Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of External Peer-Review Panel Meeting and Public Comment 


SUMMARY: EPA is announcing that the Oak Ridge Institute of Science and 
Education (ORISE), under an Interagency agreement between the 
Department of Energy and EPA, will convene an independent panel of 
experts and organize and conduct an external peer-review workshop to 
review the external review draft documents titled, ``Toxicological 
Review of TetraBDE (BDE-47): In Support of Summary Information in the 
Integrated Risk Information System (IRIS)'' (NCEA-S-2537); 
``Toxicological Review of PentaBDE (BDE-99): In Support of Summary 
Information in the Integrated Risk Information System (IRIS)'' (NCEA-S-
2538); ``Toxicological Review of HexaBDE (BDE-153): In Support of 
Summary Information in the Integrated Risk Information System (IRIS)'' 
(NCEA-S-2539); and ``Toxicological Review of DecaBDE (BDE-209): In 
Support of Summary Information in the Integrated Risk Information 
System (IRIS)'' (NCEA-S-2540). The EPA also is announcing a public 
comment period for the external review draft documents.
    The public comment period and the external peer-review workshop are 
separate processes that provide opportunities for all interested 
parties to comment on the document. In addition to consideration by 
EPA, all public comments submitted in accordance with this notice will 
also be forwarded to ORISE for consideration by the external peer-
review panel prior to the workshop.
    EPA is releasing these draft documents solely for the purpose of 
pre-dissemination peer review under applicable information quality 
guidelines. These documents have not been formally disseminated by EPA. 
They do not represent and should not be construed to represent any 
Agency policy or determination. ORISE invites the public to register to 
attend this workshop as observers. In addition, ORISE invites the 
public to give brief

[[Page 77016]]

oral comments at the workshop regarding the draft documents under 
review. The draft documents and EPA's peer-review charge are available 
via the Internet on NCEA's home page under the Recent Additions and the 
Publications menus at http://www.epa.gov/ncea. When finalizing the 
draft documents, EPA will consider ORISE's report of the comments and 
recommendations from the external peer-review workshop and any public 
comments that EPA receives in accordance with this notice.

DATES: The external peer-review panel workshop will begin on February 
22, 2007, at 9 a.m. and end at 4 p.m. The public comment period begins 
December 22, 2006 and ends February 5, 2007. Technical comments should 
be in writing and must be received by EPA by February 5, 2007. Comments 
from the public received by this date will be submitted to the external 
peer-review panel prior to the workshop.

ADDRESSES: The external peer-review workshop will be held at The 
American Geophysical Union, 2000 Florida Avenue NW., Washington, DC, 
20009-1277. ORISE is organizing, convening, and conducting the peer-

I. Summary of Information About the Integrated Risk Information System 

    IRIS is a database that contains potential adverse human health 
effects information that may result from chronic (or lifetime) exposure 
to specific chemical substances found in the environment. The database 
(available on the Internet at http://www.epa.gov/iris) contains 
qualitative and quantitative health effects information for more than 
500 chemical substances that may be used to support the first two steps 
(hazard identification and dose-response evaluation) of a risk 
assessment process. When supported by available data, the database 
provides oral reference doses (RfDs) and inhalation reference 
concentrations (RfCs) for chronic health effects, and oral slope 
factors and inhalation unit risks for carcinogenic effects. Combined 
with specific exposure information, government and private entities can 
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.

II. Workshop Information

    Members of the public may attend the workshop as observers, and 
there will be a limited time for comments from the public. Please let 
ORISE know if you wish to make oral comments during the workshop prior 
to the meeting. Space is limited, and reservations will be accepted on 
a first-come, first-served basis.

EPA's policy to include all comments it receives in the public docket 
without change and to make the comments available online at http://www.regulations.gov, including any personal information provided,

restricted by statute. Do not submit information that you

[[Page 77017]]

consider to be CBI or otherwise protected through www.regulations.gov

system, which means EPA will not know your identity or contact 
information unless you provide it in the body of your comment. If you 
send an e-mail comment directly to EPA without going through 
www.regulations.gov, your e-mail address will be automatically captured 
and included as part of the comment that is placed in the public docket

comment, EPA recommends that you include your name and other contact 
information in the body of your comment and with any disk or CD-ROM you 
submit. If EPA cannot read your comment due to technical difficulties 
and cannot contact you for clarification, EPA may not be able to 
consider your comment. Electronic files should avoid the use of special 
characters, any form of encryption, and be free of any defects or 
viruses. For additional information about EPA's public docket visit the 
EPA Docket Center homepage at http://www.epa.gov/epahome/dockets.htm.
    Docket: Documents in the docket are listed in the 
www.regulations.gov index. Although listed in the index, some 
information is not publicly available, e.g. CBI or other information 
whose disclosure is restricted by statute. Certain other materials, 
such as copyrighted material, are publicly available only in hard copy. 
Publicly available docket materials are available either electronically 
in www.regulations.gov or in hard copy at the OEI Docket in the EPA 
Headquarters Docket Center.
