ENVIRONMENTAL PROTECTION AGENCY
[FRL-9457-8; Docket ID No. EPA-HQ-ORD-2011-0390]
Draft Toxicological Review of 1,4-Dioxane: 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 1,4-Dioxane: In Support of Summary
Information on the Integrated Risk Information System (IRIS)'' (EPA/
635/R-11/003). New studies regarding the toxicity of 1,4-dioxane
through the inhalation route of exposure are available that were not
included in the 1,4-dioxane assessment that was posted on the IRIS
database in 2010 (U.S. EPA, 2010). These studies have been incorporated
into the previously posted assessment for review (U.S. EPA, 2010). 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 permits.
The listening session will be held on October 18, 2011, 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 would like 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 August 31, 2011, and ends
October 31, 2011. Comments should be in writing and must be received by
EPA by October 31, 2011.
The listening session on the draft assessment for 1,4-dioxane will
be held on October 18, 2011, beginning at 9 a.m. and ending at 4 p.m.,
Eastern Daylight Time or when the last presentation has been completed.
To attend the listening session, interested parties should register no
later than October 11, 2011. To present at the listening session,
indicate in your registration that you would like to make oral comments
at the session and provide the length of your presentation. To attend
the listening session, register by October 11, 2011 via e-mail at

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. If no speakers have
registered by October 11, 2011, the listening session will be
cancelled, and EPA will notify those registered of the cancellation.

SUPPLEMENTARY INFORMATION:
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.
