Child-Specific Exposure Factors Handbook

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

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

SUMMARY: EPA is announcing a 60-day public comment period for the 
external review draft document titled, ``Child-Specific Exposure 
Factors Handbook'' (EPA/600/R-06/096A). The draft document was prepared 
by the National Center for Environmental Assessment within EPA's Office 
of Research and Development. The ``Child-Specific Exposure Factors 
Handbook'' provides a summary of statistical data on various exposure 
factors used in assessing children's exposures, including: drinking 
water consumption; soil ingestion and mouthing behavior; inhalation 
rates; dermal factors including skin surface area and soil adherence 
factors; consumption of retail and home-grown foods; breast milk 
intake; and activity pattern data. This Handbook serves as a resource 
for exposure assessors for calculating children's exposures. An interim 
final version of this handbook was published in 2002. This updated 
version provides analysis of exposure factors data using the age groups 
for children recommended in the EPA document entitled, ``Guidance on 
Selecting Age Groups for Monitoring and Assessing Childhood Exposures 
to Environmental Contaminants'' (EPA/630/P-03/003F) (Available on line 
at https://cfpub.epa.gov/ncea/cfm/recordisplay.cfm?deid=146583).
    EPA is releasing the draft ``Child-Specific Exposure Factors 
Handbook'' 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. EPA will 
consider any public comments submitted in accordance with this notice 
when revising the document.

ends December 5, 2006. Technical comments should be in writing and must

your comment due to technical difficulties and cannot contact you for 
clarification, EPA may not be able to consider your comment. Electronic 
files should avoid the use of special characters, any form of 
encryption, and be free of any defects or viruses. For additional 
information about EPA's public docket visit the EPA Docket Center 
homepage at www.epa.gov/epahome/dockets.htm.

comments to www.regulations.gov are not affected by the flooding and 
will remain the same.
