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.Start Printed Page 2685

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).

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.
