SUMMARY:
EPA is announcing a listening session to be held on Monday, July 6, 2009, during the public comment period for the external review draft document titled, "Toxicological Review of 1,4-Dioxane: In Support of Summary Information on the Integrated Risk Information System (IRIS)" (EPA/635/R-09/005). EPA is also announcing that Versar, Inc., an EPA contractor for external scientific peer review, will convene an independent panel of experts and organize and conduct an external peer review workshop to review the external review draft titled, "Toxicological Review of 1,4-Dioxane: In Support of Summary Information on the Integrated Risk Information System (IRIS) (EPA/635/R-09/005)." The public may also attend this workshop as observers through a registration process, and time will be set aside for observers to give brief oral comments at the workshop regarding the draft document under review. EPA will consider public comments and recommendations from the expert panel workshop as EPA finalizes the draft document.
EPA previously announced the 60-day public comment period (ending July 6, 2009) for the draft document in the Federal Register on May 7, 2009 (74 FR 21361). 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 aforementioned FR notice (May 7, 2009) to Versar, Inc. for consideration by the external peer review panel prior to the workshop. Listening session participants who wish to have their comments available to the external peer reviewers should also submit written comments during the public comment period using the detailed and established procedures included in the aforementioned FR notice (May 7, 2009). Comments submitted to the docket prior to the end of the public comment period will be submitted to the external peer reviewers and considered by EPA in the disposition of public comments. Comments received in the docket after the public comment period closes will not be submitted to the external peer reviewers. Public comments submitted during the 60-day public comment period ending July 6, 2009, may be observed at http://www.regulations.gov under Docket ID no. EPA-HQ-ORD-2009-0210. EPA intends to consider the comments and recommendations from the listening session, the external peer review workshop, and any public comments that EPA receives in accordance with the May 7, 2009, Federal Register notice (74 FR 21361).
EPA released this draft document as stated in the Federal Register notice (74 FR21361) solely for the purpose of pre-dissemination public review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination.

SUPPLEMENTARY INFORMATION:
I. Summary of Information About the Integrated Risk Information System (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 the 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.
II. Listening Session Information
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 workshop. EPA welcomes the scientific and technical 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 in response to the independent external peer review and public comments. All presentations will become part of the official and public record.
III. Workshop Information
Members of the public may attend the workshop as observers, and there will be a limited time for oral comments from the public. Pre-registration is strongly recommended as space is limited, and registrations will be accepted on a first-come, first-served basis. The deadline for pre-registration is August 10, 2009. If space allows, registrations will continue to be accepted after this date, including on-site registrations. Time will be set aside to hear comments from observers, and individuals will be limited to a maximum of five minutes. Please let Versar, Inc. know if you wish to make comments during the workshop by registering as detailed in this FR notice and indicating your intent to make oral comments.
Dated: May 29, 2009.
