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.

FOR FURTHER INFORMATION CONTACT: Christina Scheltema, Manager for 
disulfoton, Special Review and Reregistration Division (7508C), Office 
of Pesticide Programs, Environmental Protection Agency, 1200 
Pennsylvania Ave., NW., Washington, DC 20460; telephone number: (703)

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.
