review 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 EPA's Office of Research and 
Development. EPA previously announced the 60-day public comment period 
(ending November 23, 2009) for the draft document in the Federal 
Register on September 24, 2009 (74 FR 48735). 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 September 24, 2009, Federal 
Register notice (74 FR 48735) to Versar, Inc. for consideration by the 
external peer-review panel prior to the workshop.

EPA's peer-review charge are available primarily via the Internet on 
NCEA's home page under the Recent Additions and Publications menus at

Versar's report of the comments and recommendations from the external

SUPPLEMENTARY INFORMATION:

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.
