methidathion (Supracide) Availability of Interim RED 5/02

[OPP-2002-0064; FRL-7177-6]
Organophosphate Pesticides; Methidathion, Availability of Interim
Reregistration Eligibility Decision Document
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
SUMMARY: This notice announces the availability of the Interim
Registration Eligibility Decision (interim RED) document for the
organophosphate pesticide (OP), methidathion. This interim decision was
developed as part of the OP pilot public participation process that the
EPA and the United States 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 OPs under the Federal Insecticide,
Fungicide and Rodenticide Act (FIFRA).
DATES: The interim RED document for methidathion is currently available
in the OP Public Regulatory Docket under docket control number OPP-

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
decision documents for methidathion, 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 listed under FOR

Friday, excluding legal holidays. The PIRIB telephone number is (703)
II. What Action is the Agency Taking?
    EPA has assessed the risks of methidathion and reached an Interim
Reregistration Eligibility Decision (interim RED) for this OP. Provided
that risk mitigation measures are adopted, methidathion fits into its
own risk cup-its individual, aggregate risks are within acceptable
levels. Methidathion is also eligible for reregistration, pending a
full reassessment of the cumulative risk from all OP pesticides. Used
on a variety of agricultural crops, predominantly alfalfa, citrus, and
cotton, methidathion residues in food and drinking water do not pose
risk concerns. Methidathion has no residential uses. EPA considered the
mitigation proposal submitted by the technical registrant, as well as
comments and mitigation ideas from other interested parties, and has
decided on a number of label amendments (restrictions) to mitigate
risks of concern posed by the uses of methidathion. With the
implementation of these mitigation measures, methidathion's worker and
ecological risks also will be below levels of concern for
    The methidathion interim RED was made through the OP 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, 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 OP
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 RED, which concludes the pilot public
participation process for methidathion. As part of the pilot public
participation process, numerous opportunities for public comment were
offered as the interim RED was being developed. The methidathion
interim RED is issued in final, without a formal public comment period.
The OP Public Regulatory Docket remains open; however, and any comments
submitted in the future will be placed in the docket.
    The revised risk assessments for methidathion were released to the
public through a notice published in the Federal Register of December
8, 1999 (OPP-34213), (FRL-6399-2).
    EPA's next step under the FQPA is to consider available information
on the basis of cumulative risk encompassing all of the OP pesticides,
sharing a common mechanism of toxicity. The tolerance reassessment
decision for methidathion cannot be considered final until the
cumulative risks for all of the OPs is considered. The Agency may need
to pursue further risk management measures at that time.
