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; extension.

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

SUMMARY: EPA announced a 60-day public comment period on August 31, 
2011 (76 FR 54227) 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). On September 15, 2011, the public comment period 
was extended by one week because of a one-week delay in the release of 
the Toxicological Review to the public (76 FR 57033). In this Notice, 
EPA is extending the public comment period an additional 30 days to 
December 7, 2011, at the request of the American Chemistry Council's 
Oxo Process Panel. 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 
for the purposes of public comment and peer review. This draft 
assessment is not final as described in EPA's information quality 
guidelines, and it does not represent and should not be construed to 
represent Agency policy or views. 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. 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.

DATES: The public comment period will be extended to end December 7, 
2011. Comments should be in writing and must be received by EPA by 
December 7, 2011.
