IV. What Action is EPA Taking in this Notice?

EPA has assessed the risks of chlorpyrifos and reached an interim risk management decision for this organophosphate pesticide. Provided that risk mitigation measures are adopted, chlorpyrifos fits into its own risk cup; its individual, aggregate risks are within acceptable levels. Used on numerous food crops (corn, beans, peas, sugar beets, cole crops, cucurbits, tree fruits, tree nuts, grapes, and berries, among others) chlorpyrifos residues in food and drinking water do not pose risk concerns. With previous mitigation eliminating homeowner's and children's exposure around the home and the phase out of the termiticide uses, chlorpyrifos fits into its own “risk cup.” With other mitigation measures, worker and ecological risks will be acceptable taking into account the benefits of use, except for the open pour dust formulations which are ineligible for reregistration at this time.

The interim risk management decision document for chlorpyrifos was developed as part of 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 document for chlorpyrifos.

In addition, this notice starts a 60-day public participation period during which the public is encouraged to submit written comments on the interim risk management decision document for chlorpyrifos. Failure to participate or comment as part of this opportunity will in no way prejudice or limit a commenter's opportunity to participate fully in any later notice and comment processes. Comments submitted will become part of the Agency record for chlorpyrifos. The preliminary risk assessments for chlorpyrifos were released to the public on October 27, 1999 (64 FR 57876) (FRL-6389-3), through a notice published in the Federal Register. The revised risk assessments for chlorpyrifos were released to the public on August 16, 2000 (65 FR 49982) (FRL-6595-7), through a notice published in the Federal Register.

EPA's next step under FQPA is to consider the cumulative risks of the organophosphate pesticides, which share a common mechanism of toxicity. The interim risk management decision document on chlorpyrifos cannot be considered final until this consideration of organophosphate cumulative risks is complete.

When the cumulative risks of the organophosphate pesticides have been considered, EPA will issue its final tolerance reassessment decision for chlorpyrifos and further risk mitigation measures may be needed.
