ENVIRONMENTAL PROTECTION AGENCY
[OPP-2002-0055; FRL-7187-7]
Organophosphate Pesticides; Disulfoton; Availability of Interim
Risk Management Decision Document
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This notice (or ``action'') announces the availability of the
Interim Reregistration Eligibility Decision (IRED) document and
technical support documents for the organophosphate (OP) pesticide,
disulfoton. These documents have been developed using a public
participation process designed by EPA and the U.S. Department of
Agriculture (USDA) to involve the public in the reassessment of
pesticide tolerances under the Food Quality Protection Act (FQPA) and
the reregistration of individual OPs under the Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA). This notice starts a 30-day
public comment period for disulfoton, during which the public is
invited to submit comments on the Agency's risk management decision.
This comment period will allow growers and other stakeholders one final
opportunity to submit new information on disulfoton alternatives and
benefits for uses that are being phased out. Comments concerning the
phase out must include specific information on current disulfoton use,
timing of applications, target pests, available alternatives, and the
cost and efficacy of alternatives, to be considered by the Agency.
DATES: Comments on the IRED for disulfoton must be identified by docket
ID number OPP-2002-0055 and must be received by EPA on or before August
16, 2002 to be considered by the Agency.
ADDRESSES: You may submit comments by mail, electronically, or in
person. Please follow the detailed instructions for each method as
described under SUPPLEMENTARY INFORMATION. To ensure proper receipt by
EPA, it is imperative that you identify docket ID number OPP-2002-0055
in the subject line on the first page of your response.

III. What Action is the Agency Taking?
A. General Information
    For the OP pesticide disulfoton, the Agency is announcing the
availability of the IRED document and supporting technical documents.
EPA has assessed the risks associated with the use of disulfoton and
reached an interim reregistration eligibility decision for disulfoton.
The disulfoton IRED and supporting technical documents were developed
using the OP public participation process, which was designed to
increase transparency and maximize stakeholder involvement and to
provide numerous opportunities for public comment. You can read more
about the OP public participation process at http://www.epa.gov/
pesticides/op/process.htm. Below is a brief summary of EPA's interim
decision, which is fully described in disulfoton's IRED document.
B. Disulfoton Decision
    EPA has determined that disulfoton is eligible for reregistration,
pending a full reassessment of the cumulative risk from all OP
pesticides, and provided that all the conditions identified in the IRED
document are satisfied, including implementation of risk mitigation
measures. Without implementation of the risk mitigation measures, the
Agency has determined that disulfoton products may pose unreasonable
adverse effects on human health and the environment. Therefore, EPA
expects that registrant will implement the risk mitigation measures as
soon as possible. The IRED document describes, in detail, what is
necessary for implementing the risk mitigation measures, such as
submission of label amendments for end-use products and submission of
any required data. Mitigation measures for disulfoton include a phase
out of disulfoton use on wheat, barley, potatoes, and commercially
grown ornamentals by June 2005. Should a registrant fail to implement
any of the risk mitigation identified in the IRED document, the Agency
may take regulatory action to address risk concerns from the use of
disulfoton.
    EPA is taking comment on benefits associated with disulfoton use in
response to grower concerns about the benefits assessment used to
support the interim RED for disulfoton. There will be a 30-day public
comment period to allow growers and other stakeholders an opportunity
to submit any new use and usage information relevant to the risk
management decision for disulfoton. Comments concerning uses being
phased out must include specific information oncurrent disulfoton use,
timing of applications, target pests, available alternatives, and the
cost and efficacy of alternatives, to be considered by the Agency.
C. Next Steps
    EPA's next step under FQPA is to consider a cumulative risk
assessment and risk management decision encompassing all the OP
pesticides, which share a common mechanism of toxicity. Because the
Agency has not yet finished its consideration of the cumulative risks
for the OPs, the Agency's interim decisions do not fully satisfy the
reassessment of the existing food residue tolerances as required by
FQPA for disulfoton. When the Agency has considered the cumulative
risks for the OPs, tolerances for disulfoton will be reassessed along
with the other OP pesticides. At that time, the Agency will complete
the FQPA requirements for the OPs and make a final reregistration
eligibility decision, which may include further risk mitigation
measures.
