Sensitive individuals. Since the available information reliably supports that IMMGV will not produce adverse effects in humans of any age as a result of exposure by ingestion, dermal contact, or inhalation, and indeed that IMMGV appears to be biologically inactive in other than its natural host, AgriVir, LLC concludes that there is a reasonable certainty that no harm to sensitive persons will result from dietary exposure to residues which could occur as a result of approval of this petition.

G. International Tolerances There are no Codex maximum residue levels established for residues of IMMGV. IMMGV containing products are presently not registered for pest control outside of the U. S.

Framework for Application of the Toxicity Equivalence Methodology for Polychlorinated Dioxins, Furans, and Biphenyls in Ecological Risk Assessment ( External Review Draft); Notice of Availability AGENCY: Environmental Protection Agency. ACTION: Notice of availability and opportunity for public comment.

SUMMARY: The U. S. Environmental Protection Agency ( EPA) is announcing a 60 day public comment period for the draft document titled Framework for Application of the Toxicity Equivalence Methodology for Polychlorinated Dioxins, Furans, and Biphenyls in Ecological Risk Assessment. The document is intended to describe a methodology for assessing ecological risks associated with complex mixtures of dioxins, furans, and dioxin like PCBs in the environment. EPA will consider the public comments in revising the document.

DATES: Comments must be received by September 29, 2003. ADDRESSES: The draft is available via the Internet at http:// cfpub. epa. gov/ ncea/ raf/ recordisplay. cfm? deid= 55669.

II. Background Polychlorinated dioxins ( PCDDs), furans ( PCDFs), and biphenyls ( PCBs) commonly occur as complex mixtures in the environment. For more than a decade, EPA and other organizations have estimated the combined risks that such mixtures pose to human health using a method known as the toxicity equivalence methodology. The methodology is based on findings that certain PCDDs, PCDFs, and PCBs share a common mechanism of action for their effects but differ in potency. The methodology uses potency factors ( such as Toxicity Equivalence Factors, or TEFs) assigned to each chemical in the mixture as a way of integrating the risks from the entire mixture. Application in ecological risk assessments has proceeded more slowly than in human health risk assessment, in part because of the variety of species from different taxonomic classes ( e. g., fish, birds, and mammals) to be considered. As both data and experience with the methodology have accumulated, however, experts have concluded that the toxicity equivalence methodology can strengthen assessments of ecological risks. At a World Health Organization consultation in 1997, international consensus TEFs for PCDDs, PCDFs, and PCBs were reviewed and the toxicity equivalence methodology expanded to include class specific TEFs for mammals, birds and fish. In 1998, EPA and the U. S. Department of Interior sponsored a workshop that recommended the development of further guidance on application of the toxicity equivalence methodology. This draft framework has been developed in direct response to that workshop recommendation by a technical panel under EPA's Risk Assessment Forum. Organized in accordance with EPA's Guidelines for Ecological Risk Assessment ( 63 FR 26846), this framework is intended to assist EPA scientists in using the methodology, as well as to inform EPA decision makers, other agencies, and the public about this methodology. It provides ecological risk assessors with an understanding of the uncertainties associated with the application of the methodology in general and with situation specific decisions made in applying the VerDate jul< 14> 2003 16: 40 Jul 29, 2003 Jkt 200001 PO 00000 Frm 00056 Fmt 4703 Sfmt 4703 E:\ FR\ FM\ 30JYN1.

The draft framework also discusses several potential advantages of the toxicity equivalence methodology compared with alternative methods for estimating risks from mixtures of dioxin like chemicals. The document is undergoing peer review concurrent with the public comment period described in this notice. This framework is not a regulation nor is it intended to substitute for federal regulations. It does not establish any substantive `` rules'' under the Administrative Procedure Act or any other law and will have no binding effect on EPA or any regulated entity.
