ENVIRONMENTAL PROTECTION AGENCY

[FRL-9108-5; Docket ID No. EPA-HQ-ORD-2009-0613]

 
Exposure Factors Handbook: 2009 Update

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Peer-Review Workshop.

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

SUMMARY: EPA is announcing that Eastern Research Group, Inc. (ERG), an 
EPA contractor for external scientific peer review, will convene an 
independent panel of experts and organize and conduct an external peer-
review workshop on March 3-4, 2010, to review the external review draft 
document titled, ``Exposure Factors Handbook 2009 Update'' (EPA/600/R-
09/052A). EPA previously announced the 60-day public comment period 
(ending December 7, 2009) for the draft document in the Federal 
Register on October 7, 2009 (74 FR 51592). The draft document was 
prepared by the National Center for Environmental Assessment (NCEA) 
within EPA's Office of Research and Development. The Exposure Factors 
Handbook provides information on various physiological and behavioral 
factors commonly used in assessing exposure to environmental chemicals. 
The handbook was first published in 1989 and was updated in 1997. This 
updated version incorporates data available since 1997 up to June 2009. 
It also reflects the revisions made to the Child-Specific Exposure 
Factors Handbook, which was updated and published in 2008. Each chapter 
in the revised Exposure Factors Handbook presents recommended values 
for the exposure factors covered in the chapter as well as a discussion 
of the underlying data used in developing the recommendations.
    The public comment period and the external peer-review workshop are 
separate processes that provide opportunities for all interested 
parties to comment on the document. EPA intends to forward public 
comments submitted in accordance with the October 7, 2009, Federal 
Register notice (74 FR 51592) to ERG, for consideration by the external 
peer-review panel prior to the workshop. EPA will consider public 
comments and recommendations from the expert panel workshop as EPA 
finalizes the draft document.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It 
does not represent and should not be construed to represent any Agency 
policy or determination.
    ERG invites the public to register to attend this workshop as 
observers. In addition, ERG invites the public to give oral comments at 
the workshop regarding the draft document under review. Members of the 
public interested in making oral comments at the workshop should also 
provide ERG with an electronic copy of their comments. Space is 
limited, and reservations will be accepted on a first-come, first-
served basis. The draft document and EPA's peer-review charge are only 
available via the Internet on NCEA's home page under the Recent 
Additions menu at http://www.epa.gov/ncea. In preparing a final report, 
EPA will consider ERG's report of the comments and recommendations from 
the external peer-review workshop and any public comments that EPA 
received.

DATES: The peer-review panel workshop will begin on Wednesday, March 3, 
2010, at 8 a.m., and will end on Thursday, March 4, 2010, at

SUPPLEMENTARY INFORMATION:

I. Information About the Document

    The Exposure Factors Handbook provides a summary of the available 
statistical data on various factors used in assessing human exposure. 
This Handbook is aimed at exposure assessors inside the Agency as well 
as those outside who use data on standard factors to calculate human 
exposure to toxic chemicals. These factors include: Drinking water 
consumption; mouthing behavior; soil ingestion rates; inhalation rates; 
dermal factors, including skin area and soil adherence factors; 
consumption of fruits and vegetables, fish, meats, dairy products, and 
homegrown foods; breast milk intake; human activity factors; consumer 
product use; and residential characteristics. Recommended values are 
for the general population and also for various segments of the 
population who may have characteristics different from the general 
population.
