Organophosphate Pesticides; Availability of Risk Management Decision Documents
This notice announces the availability of the risk management decision documents for two organophosphate pesticides, chlorpyrifos-methyl and ethion. These decision documents have been developed as part of the public participation process that EPA and the United States 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).

II. What Action is the Agency Taking? Back to Top
EPA has assessed the risks of chlorpyrifos-methyl and ethion, and reached a Report on FQPA Tolerance Reassessment Progress and Interim Risk Management Decision (TRED) and a Reregistration Eligibility Decision (RED) for these two organophosphate pesticides, respectively.
1. Chlorpyrifos-methyl TRED. Initially registered in 1985, chlorpyrifos-methyl is not subject to reregistration but is being evaluated with other organophosphate pesticides under FQPA. An insecticide used on stored grain, chlorpyrifos-methyl has significant data gaps including developmental neurotoxicity studies required for all organophosphate pesticides under FQPA to evaluate their safety to children, and chemical-specific occupational exposure studies. Registrants of chlorpyrifos-methyl have requested voluntary cancellation of their products rather than develop the additional data requested by EPA to complete the toxicology data base. The chlorpyrifos-methyl TRED summarizes EPA's assessment of dietary and occupational risk from exposure to this pesticide, and identifies mitigation measures necessary to address these risks until all uses and registrations are phased out.
2. Ethion RED. An organophosphate insecticide, ethion is used primarily to control insects on citrus, mainly oranges and grapefruit in Florida, and also to control flies and ticks on cattle. Ethion has no residential uses, and residues in food are not of concern; however, EPA has risk concerns for workers handling this pesticide, as well as ecological risk concerns. Registrants of ethion have requested voluntary cancellation of their products, rather than committing to develop the additional data requested by EPA to assess risks for reregistration. The ethion RED summarizes EPA's worker and ecological risk conclusions, and identifies mitigation measures necessary to address these risks until all uses and registrations are phased out.
The risk management decisions for chlorpyrifos-methyl and ethion 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 risk management decision documents, which conclude the pilot public participation process for chlorpyrifos-methyl and ethion. As part of the pilot public participation process, numerous opportunities for public comment were offered as these risk management decision documents were being developed. The chlorpyrifos-methyl and ethion risk management decision documents therefore are issued in final, without a formal public comment period. The docket remains open, however, and any comments submitted in the future will be placed in the public docket.
The risk assessments for chlorpyrifos-methyl and ethion, were released to the public through the following notices published in the Federal Register.
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 risk management decision documents on chlorpyrifos-methyl and ethion, however, represent the Agency's final registration and reregistration eligibility decisions for these pesticides under the organophosphate pesticide review process.
When the cumulative risk assessment for the organophosphate pesticides has been completed, EPA will issue its final tolerance reassessment decision for chlorpyrifos-methyl. Tolerance revocations for ethion will be finalized when the cancellations become effective.
