Period; extension. 

SUMMARY: EPA announced a 60-day 

public comment period on August 31, 

2011 (76 FR 54225) for the external 

review draft human health assessment 

titled, ‘‘Toxicological Review of 1,4- 

Dioxane: In Support of Summary 

Information on the Integrated Risk 

Information System (IRIS)’’ (EPA/635/ 

R–11/003). New inhalation studies 

regarding the toxicity of 1,4-dioxane are 

now included in the 1,4-dioxane 

assessment. EPA is extending the public 

comment period because of a 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. 

DATES: The public comment period will 

be extended to end November 15, 2011. 

Comments should be in writing and 

must be received by EPA by November 

15, 2011.
