Draft Toxicological Review of Trichloroacetic Acid: In Support of 
the Summary Information in 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 public comment period and a public 
listening session for the external review draft document titled, 
``Toxicological Review of Trichloroacetic Acid: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)'' (EPA/
635/R-09/003A). The draft document was prepared by the National Center 
for Environmental Assessment (NCEA) within the EPA's Office of Research 
and Development (ORD). The public comment period and the external peer-
review workshop, which will be scheduled at a later date and announced 
in the Federal Register, are separate processes that provide 
opportunities for all interested parties to comment on the document. 
EPA intends to forward the public comments that are submitted in 
accordance with this notice to the external peer-review panel prior to 
the meeting for their consideration. When finalizing the draft 
document, EPA intends to consider any public comments that EPA receives 
in accordance with this notice.
    EPA is also announcing a listening session to be held on November 
4, 2009, during the public comment period for this draft document. This 
listening session is a step in EPA's revised IRIS process, announced on 
May 21, 2009, to develop human health assessments for inclusion in the 
IRIS database. 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 
during the public comment period and before the external peer review 
meeting. EPA welcomes the scientific and technical 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 in response to the independent external peer review and the 
public comments. All presentations will become part of the official 
public record.
    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.

DATES: The public comment period begins September 24, 2009, and ends 
November 23, 2009. Technical comments should be in writing and must be 
received by EPA by November 23, 2009.
    The listening session on the draft IRIS health assessment for 
trichloroacetic acid will be held on November 4, 2009, beginning at 9 
a.m. and ending at 4 p.m., Eastern Daylight Time. If you want to make a 
presentation at the listening session, you should register by October 
28, 2009, indicate that you wish to make oral comments at the session, 
and indicate the length of your presentation. When you register, please 
indicate if you will need audio-visual aid (e.g., lap top and slide 
projector). In general, each presentation should be no more than 30 
minutes. If, however, there are more requests for 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.

[[Page 48736]]

If no speakers have registered by October 28, 2009, the listening 
session will be cancelled and EPA will notify those registered of the 
cancellation.
    Listening session participants who want EPA to share their comments 
with the external peer reviewers 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. Comments submitted to the docket prior to the end of the public 
comment period will be submitted to the external peer reviewers and 
considered by EPA in the disposition of public comments. All comments 
must be submitted to the docket, but comments received after the public 
comment period closes will not be submitted to the external peer 
reviewers.

Support of Summary Information on the Integrated Risk Information

SUPPLEMENTARY INFORMATION:

I. Information About 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.

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.

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 http://www.regulations.gov or in hard copy at the OEI Docket in the 
EPA Headquarters Docket Center.
