Draft Toxicological Review of n-Butanol: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Public Comment Period and Listening Session.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing a 60-day public comment period and a public 
listening session for the external review draft human health assessment 
titled, ``Toxicological Review of n-Butanol: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)'' (EPA/
635/R-11/081A). 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.
    The listening session will be held on October 5, 2011, during the 
public comment period for this draft assessment. 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 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.
    The listening session on the draft assessment for n-Butanol will be 
held on October 5, 2011, beginning at 9 a.m. and ending at 4 p.m., 
Eastern Daylight Time or when the last presentation has been completed. 
To attend the listening session, interested parties should register no 
later than September 28, 2011. To present at the listening session, 
indicate in your registration that you would like to make oral comments 
at the session and provide the length of your presentation. To 
register, please contact Ms. Stephanie Sarraino at Versar, Inc., by e-
mail at ssarraino@versar.com or by telephone at 703-750-3000, extension

session, provide your name, organization, contact information, any 
sponsorship information, whether you will be a speaker or an observer, 
and if you are a speaker, the approximate length of your presentation. 
When you register, please indicate if you will need audio-visual 
equipment (e.g., laptop computer and slide projector). In general, each 
presentation should be no more than 30 minutes. If, however, there are 
more requests for presentations than the allotted time allows, then the 
time limit for each presentation will be adjusted. A copy of the agenda 
for the listening session will be available at the meeting. If no 
speakers have registered by September 28, 2011, the listening session 
will be cancelled, and EPA will notify those registered of the 
cancellation.

SUPPLEMENTARY INFORMATION: 

I. Information About IRIS

    EPA's IRIS program 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.
