II. Background

A. What action is the agency taking?

Pursuant to 40 CFR 155.58(c), this notice announces the availability of EPA's final registration review decision for methamidophos, case 0043. Methamidophos is a restricted use organophosphate insecticide, that as of 2009 was registered for use on potato, cotton, tomato, and alfalfa grown for seed. However, in 2009, the sole methamidophos registrant, Bayer CropScience, informed the Agency that they were requesting to voluntarily cancel all of their remaining methamidophos product registrations. Following publication of aFederal Registernotice announcing receipt of those requests and the completion of the corresponding public comment period, the Agency issued the product cancellation order on September 23, 2009, for all methamidophos product registrations. Details of the cancellation dates can be found in the Methamidophos Registration Review Decision document.

Pursuant to 40 CFR 155.57, a registration review decision is the Agency's determination whether a pesticide meets, or does not meet, the standard for registration in FIFRA. EPA has considered methamidophos in light of the FIFRA standard for registration and has concluded the methamidophos registration review. No further action is needed as all registrations of methamidophos have been cancelled. The Methamidophos Final Decision document in the docket describes the Agency's rationale for issuing a registration review final decision for this pesticide.

In addition to the final registration review decision document, the registration review docket for methamidophos also includes other relevant documents related to the registration review of this case. The proposed registration review decision was posted to the docket and the public was invited to submit any comments or new information. During the 60-day comment period, no public comments were received.

Pursuant to 40 CFR 155.58(c), the registration review case docket for methamidophos will remain open until all actions required in the final decision have been completed.
