Information on the Integrated Risk Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Public Comment Period and Listening Session; 
Extension.

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

SUMMARY: EPA announced a 60-day public comment period and a listening 
session 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). EPA is extending the public 
comment period one week because of a one-week delay in the release of 
the Toxicological Review to the public. 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 26, 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.

DATES: The public comment period will be extended to end November 7, 
2011. Comments should be in writing and must be received by EPA by 
November 7, 2011.
    The listening session on the draft assessment for n-Butanol will be 
held on October 26, 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 October 19, 2011, following the instructions in the August 
31 Federal Register Notice (76 FR 54227). The location and instructions 
for entering the building can be found in the August 31, 2011, Federal
