AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of listening session.


SUMMARY: EPA is announcing a listening session to be held on November 
23, 2009, during the public comment period for the external review 
draft document entitled, ``Toxicological Review of Choroprene: In 
Support of Summary Information on the Integrated Risk Information 
System (IRIS).'' 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 prior to the external peer review

comments will be considered by the Agency as it revises the draft 
assessment in response to the independent external peer review and 
public comments. All presentations will become part of the official and 
public record.

SUPPLEMENTARY INFORMATION: 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.
