Child-Specific Exposure Factors Handbook

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Re-opening of Public Comment Period.

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

SUMMARY: EPA is re-opening the public comment period for the draft 
document titled, ``Child-Specific Exposure Factors Handbook'' (EPA/600/
R-06/096A). The document was prepared by the National Center for 
Environmental Assessment within EPA's Office of Research and 
Development.
    On October 6, 2006, EPA published a Federal Register notice (71 FR 
59107) announcing a 60-day public comment period that ended December 5, 
2006. EPA is re-opening the public comment period for an additional 30 
days in response to requests to extend the comment period.

    The Child-Specific Exposure Factors Handbook provides a summary of 
statistical data on various exposure factors used in assessing 
children's exposures. This Handbook serves as a resource for exposure 
assessors for calculating children's exposures. These factors include: 
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. An interim final version of 
this handbook was published in 2002. The updated version provides 
analysis of exposure factors data using the age groups for children as 
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 
http://cfpub.epa.gov/ncea/cfm/recordisplay.cfm?deid=146583).
    As previously stated in 71 FR 59107, 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.

DATES: The 30-day public comment period begins January 22, 2007, and 
ends February 21, 2007. Technical comments should be in writing and 
must be received by EPA by February 21, 2007.

Environmental Assessment's home page under the Recent Additions and the
