II. Background

A. What Action is the Agency Taking?

    For the OP pesticide methamidophos, the Agency is announcing the
availability of the IRED document and supporting technical documents.
EPA has assessed the risks associated with the use of methamidophos and
reached an interim reregistration eligibility decision for
methamidophos. The methamidophos 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:// Below is a brief summary of
EPA's interim decision, which is fully described in the methamidophos
IRED document.
    EPA has determined that methamidophos 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 methamidophos 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
methamidophos include a phase out of methamidophos use on cotton by
2007. 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 methamidophos.

B. What is the Agency's Authority for Taking this Action?

    The legal authority for this action falls under FIFRA, as amended
in 1988 and 1996. Section 4(g)(2)(A) of FIFRA directs that, after
submission of all data concerning a pesticide active ingredient, ``the
Administrator shall determine whether pesticides containing such active
ingredient are eligible for reregistration,'' before calling in
product-specific data on individual end-use products, and either
reregistering products or taking ``other appropriate regulatory
