[[Page 27314]]

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.
    The EPA's draft assessment and peer review charge are available via 
the Internet on the National Center for Environmental Assessment's 
(NCEA) home page under the Recent Additions and the Data and 
Publications menus at http://www.epa.gov/ncea.

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.

Director, National Center for Environmental Assessment.
