Start Preamble

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.
