Difenzoquat; Notice of Receipt of Request to Voluntarily Cancel 
Pesticide Registrations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: 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 a request by the registrant to voluntarily cancel 
their registrations of products containing the pesticide difenzoquat. 
The request would terminate difenzoquat use on barley and wheat. The 
request would terminate the last difenzoquat 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 registrant 
withdraws their request within this period. Upon acceptance of this 
request, 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.

health, and agricultural advocates; the chemical industry; pesticide 
users; and members of the public interested in the sale, distribution,

suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
     viii. Make sure to submit your comments by the comment period 
deadline identified.

II. Background on the Receipt of Requests to Cancel and/or Amend 
Registrations to Delete Uses

    This notice announces receipt by EPA of a request from registrant 
AMVAC Chemical Corporation to cancel all 3 product registrations for 
the herbicide difenzoquat. Difenzoquat is registered for use on only 
two crops, wheat and barley. In a letter dated November 2, 2009, AMVAC 
Chemical Corporation requested EPA to cancel the affected product 
registrations identified in Table 1 of this notice. If the registrant's 
request is granted, the last difenzoquat products registered in the 
United States will be canceled effective December 31, 2009.

III. What Action is the Agency Taking?

    This notice announces receipt by EPA of a request from a registrant 
to cancel difenzoquat product registrations. The affected products and 
the registrants making the requests are identified in Table 1 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: The registrants 
request a waiver of the comment period, or; the Administrator 
determines that continued use of the pesticide would pose an 
unreasonable adverse effect on the environment.
    The difenzoquat 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 Difenzoquat

    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 December 28, 2009. 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 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 difenzoquat 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.
    If the request for voluntary cancellation is granted as discussed 
in this unit, the Agency proposes to issue a cancellation order that 
will allow AMVAC to sell and distribute existing stocks of the products 
identified in Unit III. until December 31, 2010. All sale or 
distribution of existing stocks by AMVAC is prohibited after December 
30, 2010, unless that sale or distribution is solely for the purpose of 
facilitating disposal or export of the product.
    The Agency will allow persons other than the registrant to continue 
to sell and/or use existing stocks of canceled products until such 
stocks are exhausted, provided that such use is consistent with the 
terms of the previously approved labeling on, or that accompanied, the 
canceled product. The order will specifically prohibit any use of 
existing stocks that is not consistent with such previously approved 
labeling. The Agency will publish the cancellation order in the Federal 
Register.
