In general, each individual making an oral presentation will be limited to a total of three minutes. EPA ORD is conducting a prospective and retrospective independent expert review through the BOSC, of its Homeland Security Research Program, to evaluate the program’s relevance, quality, performance, and scientific leadership. The BOSC’s evaluation and recommendations will provide guidance to ORD’s National Homeland Security Research Center. Proposed agenda items for the meeting include, but are not limited to: review and discussion of the draft subcommittee report which includes overall comments and recommendations to ORD’s National Homeland Security Research Program, and responses to subcommittee charge questions.

AGENCY: SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing the availability of the final ‘‘Framework for Application of the Toxicity Equivalence Methodology for Polychlorinated Dioxins, Furans, and Biphenyls in Ecological Risk Assessment’’ (EPA/100/R–08/004). The purpose of the Framework is to assist EPA scientists in using the toxicity equivalence methodology to assess ecological risks from mixtures of dioxinlike chemicals, i.e., polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs), as well as to inform EPA decision makers, other agencies, and the public about this methodology. This framework provides an introduction to the toxicity equivalence methodology, offers considerations for how and when to apply the methodology, and presents practical examples of its use. The Framework thus serves to enhance the application of the best available science. This document is not intended to serve as guidance on how to conduct a comprehensive risk assessment for dioxin-like chemicals or to act as a regulation or binding policy. EPA’s Risk Assessment Forum oversaw the development of this document, incorporating input obtained from an expert workshop, scientists throughout the Agency, stakeholders, and a peer review by twelve experts from a range of scientific disciplines.

SUPPLEMENTARY INFORMATION: For more than a decade, EPA and other organizations have estimated the combined risks that mixtures of PCDDs, PCDFs, and PCBs pose to human health using the toxicity equivalence methodology. As both data and experience with the methodology have accumulated, experts have come to the consensus that the toxicity equivalence methodology can strengthen assessments of ecological risks as well. In 1998, EPA and DOI sponsored a workshop that recommended the development of further guidance on application of the toxicity equivalence methodology in ecological risk assessment. This framework has been developed in direct response to that workshop recommendation. EPA consulted with other federal agencies at key points during the document’s development. In July 2003, EPA released a draft Framework for a 60-day public comment period. An external peer review was conducted in 2004 by twelve experts from a range of scientific disciplines.

 Notice of Availability for the Framework for Application of the 
Toxicity Equivalence Methodology for Polychlorinated Dioxins, Furans, 
and Biphenyls in Ecological Risk Assessment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of document availability.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing 
the availability of the final ``Framework for Application of the 
Toxicity Equivalence Methodology for Polychlorinated Dioxins, Furans, 
and Biphenyls in Ecological Risk Assessment'' (EPA/100/R-08/004). The 
purpose of the Framework is to assist EPA scientists in using the 
toxicity equivalence methodology to assess ecological risks from 
mixtures of dioxin-like chemicals, i.e., polychlorinated dibenzo-p-
dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs), as well 
as to inform EPA decision makers, other agencies, and the public about 
this methodology. This framework provides an introduction to the 
toxicity equivalence methodology, offers considerations for how and 
when to apply the methodology, and presents practical examples of its 
use. The Framework thus serves to enhance the application of the best 
available science. This document is not intended to serve as guidance 
on how to conduct a comprehensive risk assessment for dioxin-like 
chemicals or to act as a regulation or binding policy. EPA's Risk 
Assessment Forum oversaw the development of this document, 
incorporating input obtained from an expert workshop, scientists 
throughout the Agency, stakeholders, and a peer review by twelve 
experts from a range of scientific disciplines.

ADDRESSES: The final document is available electronically through the 
EPA Office of the Science Advisor's Web site at: https://www.epa.gov/
osa/raf/tefframework/. A limited number of paper copies will be 
available from EPA's National Service Center for Environmental 
Publications (NSCEP), P.O. Box 42419, Cincinnati, OH 45242; telephone 
1-800-490-9198 or 513-489-8190; facsimile 301-604-3408; e-mail
