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 document titled, Toxicological Review 
of 1,1,1-Trichloroethane: In Support of Summary Information on the 
Integrated Risk Information System (IRIS) (NCEA-S-1606). The EPA also 
is announcing a public comment period for the draft document. EPA 
intends to consider comments and recommendations from the public and 
the expert panel meeting when 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. 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.

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 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 peer-review panel workshop will begin on April 20, 2007, at 
9 a.m. and end at 3 p.m. The public comment period begins February 27,

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 
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 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. Please 
let ORISE know if you wish to make comments during the workshop prior 
to the meeting by registering on the Web site at http://www.orau.gov/trichloroethane and indicating your intent to make oral comments. 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 
www.regulations.gov, including any personal information provided,

restricted by statute. Do not submit information that you consider to 
be CBI or otherwise protected through www.regulations.gov or e-mail.

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 www.epa.gov/epahome/dockets.htm.
    Docket: All 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 material, such 
as copyrighted material, will be 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.
