[OPP-341399D; FRL-6814-7]

Organophosphate Pesticides; Availability of Terbufos Interim Risk
Management Decision Documents

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.


SUMMARY: 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
interim 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).

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

I. General Information

A. Does this Action Apply to Me?

    This action is directed to the public in general, nevertheless, a
wide range of stakeholders will be interested in obtaining the interim
risk management decision documents for terbufos, including
environmental, human health, and agricultural advocates; the chemical
industry; pesticide users; and members of the public interested in the
use of pesticides on food. Since other entities also may be interested,
the Agency has not attempted to describe all the specific entities that
may be affected by this action. If you have any questions regarding the
applicability of this action to a particular entity, consult the person

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
    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-
    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.
