Notice of public comment period.
The U.S. Environmental Protection Agency (EPA) is announcing a 45-day public comment period for the external review draft document titled, “A Framework for Assessing Health Risks of Environmental Exposures to Children” (EPA/600/R-05/093A). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development (ORD).
For external scientific peer review, EPA has hired Eastern Research Group, Inc. (ERG) to convene an independent panel of experts and organize and conduct an external peer-review workshop. The date and location for the external peer-review workshop will be announced in a separate Federal Register notice, once that information is obtained by EPA. 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. In addition to consideration by EPA, all public comments submitted in accordance with this notice will also be forwarded to ERG for the external peer-review panel prior to the workshop.
EPA is releasing this external review draft document solely for the purpose of pre-dissemination peer review under applicable information quality guidelines. This draft document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination.
The 45-day public comment period begins March 14, 2006, and ends April 28, 2006. Technical comments should be in writing and must be received by EPA by April 28, 2006.
The draft document and EPA's peer-review charge are available primarily via the Internet on the National Center for Environmental Assessment's home page under the Recent Additions and Publications menus at http://www.epa.gov/ncea. A limited number of paper copies are available from the Technical Information Staff, NCEA-W; telephone: 202-564-3261; facsimile: 202-565-0050. If you are requesting a paper copy, please provide your name, mailing address, and the document title, “A Framework for Assessing Health Risks of Environmental Exposures to Children” (EPA/600/R-05/093A).
Comments may be submitted electronically via http://www.regulations.gov, by mail, by facsimile, or by hand delivery/courier. Please follow the detailed instructions Start Printed Page 13126as provided in the SUPPLEMENTARY INFORMATION section of this notice.Start Further Info

I. Information About the Document
Over the past decade, there has been a dramatic increase in the recognition of, and public health concern for, the vulnerability of children to exposure to environmental agents. Children have unusual patterns of exposure and have vulnerabilities to chemical agents that are quite distinct from those of adults, and thus require special consideration in risk assessment. Children often have disproportionately higher exposures to certain environmental toxicants because, pound-for-pound of body weight, children have higher food and water intake and breathe more air than adults. Metabolic pathways in the young, especially in the first few months after birth, are immature, and the ability to detoxify environmental agents is different from that of adults. In addition, behavior and activity patterns of children often magnify their exposures. These factors imply that children are likely to have more substantial exposures than adults to certain environmental agents. This document attempts to organize and present current knowledge and practices in a programmatic framework for assessing human health risks from exposures to environmental agents from prior to conception through adolescence. It describes this framework within the current Agency risk assessment paradigm, and includes problem formulation, analysis and risk characterization as discrete steps in the process. Moreover, this document focuses on mode of action as a context for considering the toxicokinetic and toxicodynamic differences between children and adults, and considers approaches for risk assessment in the context of uncertainty and variability in exposure and critical windows of development.
