Start Preamble


Environmental Protection Agency (EPA).




This notices announces the availability of the interim risk management decision document for terbufos. In addition, this notice starts a 60-day public participation period during which the public is encouraged to submit comments on the terbufos Start Printed Page 2210interim risk management decision document. This decision document has been developed as part of the public participation process that EPA and the U.S. Department of Agriculture (USDA) are now using for involving the public in the reassessment of pesticide tolerances under the Food Quality Protection Act (FQPA), and the reregistration of individual organophosphate pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).


The interim risk management decision documents are available under docket control number OPP-341399D.

II. What Action is the Agency Taking?

EPA has assessed the risks of terbufos and reached an Interim Reregistration Eligibility Decision (IRED) for this organophosphate pesticide. Provided that risk mitigation measures are adopted, terbufos fits into its own risk cup its individual, aggregate risks are within acceptable levels. Used on corn, sorghum, and sugar beets, terbufos residues in food and drinking water do not pose risk concerns with the implementation of certain risk mitigation measures. Terbufos has no residential uses. With other risk reduction measures, worker and ecological risks also will be substantially reduced.

The interim risk management decision documents for terbufos were made through the organophosphate pesticide pilot public participation process, which increases transparency and maximizes stakeholder involvement in EPA's development of risk assessments and risk management decisions. The pilot public participation process was developed as part of the EPA-USDA Tolerance Reassessment Advisory Committee (TRAC), which was established in April 1998, as a subcommittee under the auspices of EPA's National Advisory Council for Environmental Policy and Technology. A goal of the pilot public participation process is to find a more effective way for the public to participate at critical junctures in the Agency's development of organophosphate pesticide risk assessments and risk management decisions. EPA and USDA began implementing this pilot process in August 1998, to increase transparency and opportunities for stakeholder consultation.

EPA worked extensively with affected parties to reach the decisions presented in the interim risk management decision documents, which conclude the pilot public participation process for terbufos. As part of the pilot public participation process, numerous opportunities for public comment were offered as these interim risk management decision documents were being developed. There will also be a 60-day comment period on the interim reregistration eligibility decision and the docket will remain open after this period for any comments submitted to the Agency.

The risk assessments for terbufos were released to the public through a notice published in the Federal Register of August 12, 1998 (63 FR 43175) (FRL-6024-5), and September 1, 1999 (64 FR 34195) (FRL-6099-9).

EPA's next step under FQPA is to complete a cumulative risk assessment and risk management decision for the organophosphate pesticides, which share a common mechanism of toxicity. The interim risk management decision documents on terbufos cannot be considered final until this cumulative assessment is complete. When the cumulative risk assessment for the organophosphate pesticides has been completed, EPA will issue its final tolerance reassessment decision(s) for terbufos and further risk mitigation measures may be needed.
