AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of peer-review workshop and public comment period.

SUMMARY: EPA is announcing that the Oak Ridge Institute of Science and 
Education (ORISE), under an Interagency agreement between the 
Department of Energy and EPA, will convene an independent panel of 
experts and organize and conduct an external peer-review workshop to 
review the external review draft document titled, ``Toxicological 
Review of Tetrahydrofuran: In Support of Summary Information on the 
Integrated Risk Information System (IRIS)'' (NCEA-S-1620). The EPA also 
is announcing a public comment period for the draft document. EPA 
intends to consider comments and recommendations from the public and 
the expert panel meeting when EPA finalizes the draft document.
    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 this notice to ORISE for 
consideration by the external peer-review panel prior to the workshop.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It

observers. In addition, ORISE invites the public to give brief oral 
comments at the workshop regarding the draft document under review. The 
draft document and EPA's peer-review charge are available via the 
Internet on NCEA's home page under the Recent Additions and the Data 
and Publications menus at http://www.epa.gov/ncea. When finalizing the 

draft document, EPA intends to consider ORISE's report of the comments 
and recommendations from the external peer-review workshop and any 
public comments that EPA receives in accordance with this notice.

DATES: The peer-review panel workshop will begin on November 1, 2007, 
at 9 a.m. and end at 3 p.m. The public comment period begins August 20,

submit comments from the public received by this date to ORISE prior to 
the workshop for consideration by the panel.

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 
500 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 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. 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. Please 
let ORISE know if you wish to make comments during the workshop prior 
to the meeting by registering on the Web site at http://www.orau.gov/tetrahydrofuran
 and indicating your intent to make oral comments. Space 

is limited, and reservations will be accepted on a first-come, first-
served basis.
