[[Page 27314]]
experts and organize and conduct an external peer review workshop to
review the external review draft titled, ``Toxicological Review of 1,4-

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).

notice (74 FR21361) solely for the purpose of pre-dissemination public
review under applicable information quality guidelines. This document

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.
