Start Preamble


Environmental Protection Agency (EPA).




In accordance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is issuing a notice of receipt of a request by the registrants to voluntarily cancel all pesticide product registrations containing the pesticide diclofop-methyl. The request would cancel diclofop-methyl use in or on wheat, barley, and golf course turf and would terminate the last diclofop-methyl products registered for use in the United States. EPA intends to grant this request 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 request, or unless the registrants withdraw their request. The cancellation for diclofop-methyl products will be effective on January 1, 2018 as described in Unit II below. If this request is granted, any sale, distribution, or use of products listed in this notice will be permitted after the registrations have been cancelled only if such sale, distribution, or use is consistent with the terms as described in the final order.

A. Does this action apply to me?

This action is directed to the public in general, and may be of interest to a wide range of stakeholders including environmental, human health, and agricultural advocates; the chemical industry; pesticide users; and members of the public interested in the sale, distribution, or use of pesticides. Since others also may be interested, the Agency has not attempted to describe all the specific entities that may be affected by this action.

B. What should I consider as I prepare my comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through or email. Clearly mark the part or all of the information that you claim to be CBI.

II. Background on the Receipt of Requests To Cancel Registrations

This notice announces receipt by EPA of a request from registrants, Bayer CropScience and Bayer Environmental Science, to cancel all diclofop-methyl product registrations. Diclofop-methyl is a restricted use herbicide registered for use on wheat, barley, and golf course turf to control wild oats and annual grassy weeds. In a letter dated October 23, 2014, Bayer CropScience and Bayer Environmental Science requested EPA to cancel certain pesticide product registrations identified in Table 1 of Unit III. Specifically, Bayer requests that all diclofop-methyl registrations be cancelled effective January 1, 2018. This action will terminate the last diclofop-methyl products registered in the United States.

III. What action is the agency taking?

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

On September 24, 2014, the public phase of registration review for diclofop-methyl began with the opening of the initial docket (EPA-HQ-OPP-2014-0577) and publication of the Preliminary Work Plan (PWP) and supporting science documents. The comment period for the diclofop-methyl registration review docket was open for 60 days, from September 24, 2014 to November 24, 2014. The Agency's projected registration review timeline described in the PWP established that preliminary risk assessments would be completed by December 2018, and the final registration decision would be Start Printed Page 7589completed in 2020. The technical registrants subsequently requested cancellation of all diclofop-methyl products effective January 1, 2018.

Unless a request is withdrawn by the registrant or if the Agency determines that there are substantive comments that warrant further review of this request, EPA intends to issue an order canceling the affected registrations.

IV. What is the agency's authority for taking this action?

Section 6(f)(1) of FIFRA (7 U.S.C. 136d(f)(1)) 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.

Section 6(f)(1)(B) of FIFRA (7 U.S.C. 136d(f)(1)(B)) 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, FIFRA section 6(f)(1)(C) (7 U.S.C. 136d(f)(1)(C)) 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 EPA Administrator determines that continued use of the pesticide would pose an unreasonable adverse effect on the environment.

Because diclofop-methyl is not registered for any minor agricultural uses, this 180-day comment provision does not apply, and EPA is providing a 30-day comment period on the proposed voluntary cancellation of diclofop-methyl registrations.

V. Procedures for Withdrawal of Requests

Registrants who choose to withdraw a request for product cancellation or use deletion should submit the withdrawal in writing to the person listed under FOR FURTHER INFORMATION CONTACT. 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 that are currently in the United States and that were packaged, labeled, and released for shipment prior to the effective date of the action. If the request for voluntary cancellation is granted, the Agency intends to publish the cancellation order in the Federal Register. Because these diclofop-methyl products are reregistered pesticides, there are no known risks of concern, and the effective cancellation date for the products will occur two years prior to the time of the planned registration review decision for diclofop-methyl, the Agency expects to grant this request unless the Agency receives substantive comments that warrant further review of the request or the registrants withdraw their request. In 2015, the Agency intends to issue an order in the Federal Register canceling all registrations effective January 1, 2018. On issuance of the cancellation order, EPA anticipates allowing registrants to sell and distribute existing stocks of these products until January 1, 2018. Thereafter, registrants will be prohibited from selling or distributing the pesticides identified in Table 1 of Unit III., except for export consistent with FIFRA section 17 or for proper disposal. Persons other than registrants will generally be allowed to sell, distribute, or use existing stocks until such stocks are exhausted, provided that such sale, distribution, or use is consistent with the terms of the previously approved labeling on, or that accompanied, the canceled products.
