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
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
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
