Start Preamble


Environmental Protection Agency (EPA).




In accordance with section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, EPA is issuing a notice of receipt of requests by the registrants to voluntarily cancel their methidathion registrations. The requests would terminate the last methidathion products registered for use in the United States. EPA intends to grant these requests at the close of the comment period for this announcement unless the Agency receives substantive comments within the comment period that would merit its further review of the requests, or unless the registrants withdraw their requests within this period. Upon acceptance of these requests, any sale, distribution, or use of products listed in this notice will be permitted only if such sale, distribution, or use is consistent with the terms as described in the final order.

II. Background on the Receipt of Requests to Cancel Registrations

This notice announces receipt by EPA of requests from registrants to cancel methidathion product registrations. Methidathion is a non-systemic, organophosphate (OP) used as an insecticide/acaricide on a wide variety of terrestrial food and feed crops and terrestrial non-food crops. The pesticide acts through inhibition of acetylcholinesterase and is used to kill a broad range of insects and mites. In letters received by the Agency, the registrants have requested EPA to cancel affected product registrations identified in this notice in Table 1. Specifically, the registrants have requested voluntary cancellation of all products containing methidathion. The registrants requests will terminate the last methidathion products registered in the United States.

III. What Action is the Agency Taking?

This notice announces receipt by EPA of requests from registrants to cancel methidathion product registrations. The affected products and the registrants making the requests are identified in Tables 1 and 2 of this unit.

Under section 6(f)(1)(A) of FIFRA, registrants may request, at any time, that their pesticide registrations be canceled or amended to terminate one or more pesticide uses. Section 6(f)(1)(B) of FIFRA requires that before acting on a request for voluntary cancellation, EPA must provide a 30-day public comment period on the request for voluntary cancellation or use termination. In addition, section 6(f)(1)(C) of FIFRA requires that EPA provide a 180-day comment period on a request for voluntary cancellation or termination of any minor agricultural use before granting the request, unless:

1. The registrants request a waiver of the comment period, or

2. The Administrator determines that continued use of the pesticide would pose an unreasonable adverse effect on the environment.

The methidathion registrants have requested that EPA waive the 180-day comment period. EPA will provide a 30-day comment period on the proposed requests.

Unless a request is withdrawn by the registrant within 30 days of publication of this notice, or if the Agency determines that there are substantive comments that warrant further review of this request, an order will be issued canceling the affected registrations.

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

Section 6(f)(1) of FIFRA provides that a registrant of a pesticide product may at any time request that any of its pesticide registrations be canceled or amended to terminate one or more uses. FIFRA further provides that, before acting on the request, EPA must publish a notice of receipt of any such request in the Federal Register. Thereafter, following the public comment period, the Administrator may approve such a request.

V. Procedures for Withdrawal of Request and Considerations for Reregistration of Methidathion

Registrants who choose to withdraw a request for cancellation must submit such withdrawal in writing to the person listed under FOR FURTHER INFORMATION CONTACT, postmarked before May 7, 2010. This written withdrawal of the request for cancellation will apply only to the applicable FIFRA section 6(f)(1) request listed in this notice. If the products(s) have been subject to a previous cancellation action, the effective date of cancellation and all other provisions of any earlier cancellation action are controlling.

VI. Provisions for Disposition of Existing Stocks

Existing stocks are those stocks of registered pesticide products which are currently in the United States and which were packaged, labeled, and released for shipment prior to the effective date of the cancellation action.

In any order issued in response to these requests for cancellation of product registrations, EPA proposes to include the following provisions for the treatment of any existing stocks of the products identified or referenced in Table 1 in Unit III:

After December 31, 2012, registrants are prohibited from selling or distributing existing stocks of products containing methidathion.

After December 31, 2014, persons other than registrants are prohibited from selling or distributing existing stocks of products containing methidathion.

After December 31, 2014, existing stocks of products containing methidathion already in the hands of users can be used legally until they are exhausted, provided that such use complies with the EPA-approved label and labeling of the affected product.

If the request for voluntary cancellation is granted, the Agency intends to publish the cancellation order in the Federal Register.
