Draft Toxicological Review of Carbon Tetrachloride: In Support of 
the Summary Information in the Integrated Risk Information System 
(IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Peer Review Workshop.

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

SUMMARY: EPA is announcing that Eastern Research Group, Inc. (ERG), an 
EPA contractor for external scientific peer review, will convene an 
independent panel of experts and organize and conduct an external peer 
review workshop to review the external review draft document titled, 
``Toxicological Review of Carbon Tetrachloride: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)'' (EPA/
635/R-08/005A). EPA previously announced the 60-day public comment 
period (ending July 21, 2008) for the draft document in the Federal 
Register on May 21, 2008 (73 FR 29502). EPA will consider public 
comments and recommendations from the expert panel workshop as EPA 
finalizes the draft document.
    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. EPA intends to forward public 
comments submitted in accordance with the Federal Register notice (73 
FR 29502) to ERG for consideration by the external peer review panel 
prior to the workshop.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It 
does not represent and should not be construed to represent any Agency 
policy or determination.
    The public may attend this workshop as observers through a 
registration process, and time will be set aside for observers to give 
brief oral comments at the workshop regarding the draft document under 
review. The draft document and EPA's peer review charge are available 
via the Internet on NCEA's home page under the Recent Additions and the 
Data and Publications menus at http://www.epa.gov/ncea. When finalizing 
the draft document, EPA intends to consider the comments and 
recommendations from the external peer

SUPPLEMENTARY INFORMATION:

I. Summary of Information About the Integrated Risk Information System 
(IRIS)

    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 
540 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 data 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 oral comments from the public. Pre-
registration is strongly recommended as space is limited, and 
registrations will be accepted on a first-come, first-served basis. The 
deadline for pre-registration is October 7, 2008. If space allows, 
registrations will continue to be accepted after this date, including 
on-site registrations. Time will be set aside to hear comments from 
observers, and individuals will be limited to a maximum of five minutes 
during the morning session of peer review workshop. Please let ERG know 
if you wish to make comments during the workshop by registering on the 
Web site at https://www2.ergweb.com/projects/conferences/peerreview/register-carbontetra.htm and indicating your intent to make oral 
comments.

    Dated: August 30, 2008.
