Start Preamble


Environmental Protection Agency (EPA).




This notice announces the availability of the interim risk Start Printed Page 77784 management decision (IRED) document for the organophosphate pesticide naled. 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 document is available in the OPP Docket under docket ID number OPP-2002-0307.

III. What Action is the Agency Taking?

EPA has assessed the risks of naled and reached an IRED for this organophosphate pesticide. Provided that risk mitigation measures are adopted, naled fits into its own risk cup—its individual, aggregate risks are within acceptable levels. Used mainly to control mosquitos and to control insects on a variety of agricultural crops, naled residues in food and drinking water do not pose risk concerns. Naled may no longer be used in and around the home by residents or professional applicators. However, residents can be exposed as bystanders from wide-area mosquito control applications. With mitigation limiting homeowners' and children's exposure, naled fits into its own “risk cup.” With other mitigation measures, naled's worker and ecological risks are also below levels of concern for reregistration.

The interim risk management decision document for naled was 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 this interim risk management decision document, which conclude, the pilot public participation process for naled. As part of the pilot public participation process, numerous opportunities for public comment were offered as this interim risk management decision document was being developed. The naled interim risk management decision document, therefore, is issued without a formal public comment period concluding review of the individual organophosphate pesticide. The docket remains open, however, and any comments submitted in the future will be placed in the public docket.

The risk assessments for naled were released to the public through notices published in the Federal Register on August 12, 1998 (63 FR 43175) (FRL-6024-3), and October 6, 1999 (64 FR 54298) (FRL-6387-6).

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. This interim risk management decision document on naled 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 for naled and further risk mitigation measures may be needed.
