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.

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.

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.
