Draft Toxicological Review of Hexavalent Chromium: In Support of
Summary Information on 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 60-day public comment period and a public
listening session for the external review draft human health assessment
titled, ``Toxicological Review of Hexavalent Chromium: In Support of
Summary Information on the Integrated Risk Information System (IRIS)''
EPA/635/R-10/004C. The draft assessment was prepared by the National
Center for Environmental Assessment (NCEA) within the EPA Office of
Research and Development (ORD). EPA is releasing this draft assessment
solely for the purpose of pre-dissemination peer review under
applicable information quality guidelines. This draft assessment has
not been formally disseminated by EPA. It does not represent and should
not be construed to represent any Agency policy or determination. After
public review and comment, an EPA contractor will convene an expert
panel for independent external peer review of this draft assessment.
The public comment period and external peer review meeting are separate
processes that provide opportunities for all interested parties to
comment on the assessment. The external peer review meeting will be
scheduled at a later date and announced in the Federal Register. Public
comments submitted during the public comment period will be provided to
the external peer reviewers before the panel meeting and considered by
EPA in the disposition of public comments. Public comments received
after the public comment period closes will not be submitted to the
external peer reviewers and will only be considered by EPA if time
The listening session will be held on November 18, 2010, during the
public comment period for this draft assessment. 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 attending the listening session. EPA
welcomes the 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 after the independent
external peer review. If listening session participants want EPA to
share their comments with the external peer reviewers, they 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.
DATES: The public comment period begins September 30, 2010, and ends
November 29, 2010. Comments should be in writing and must be received
by EPA by November 29, 2010.

I. Information About IRIS
EPA's IRIS is a human health assessment program that evaluates
quantitative and qualitative risk information on effects that may
result from exposure to chemical substances found in the environment.
Through the IRIS Program, EPA provides the highest quality science-
based human health assessments to support the Agency's regulatory
activities. The IRIS database contains information for more than 540
chemical substances that can be used to support the first two steps
(hazard identification and dose-response evaluation) of the risk
assessment process. When supported by available data, IRIS provides
oral reference doses (RfDs) and inhalation reference concentrations
(RfCs) for chronic noncancer health effects and cancer assessments.
Combined with specific exposure information, government and private
entities use IRIS 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.
