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 amend to terminate uses of DDVP product registrations. DDVP is an organophosphate insecticide and fumigant registered for use in controlling flies, mosquitoes, gnats, cockroaches, fleas, and other insect pests. Formulations of DDVP include pressurized liquid, granular, emulsifiable concentrate, total release aerosol, and impregnated material. DDVP is applied with aerosols and fogging equipment, with ground spray equipment, and through slow release from impregnated materials, such as resin strips. DDVP is registered to control insect pests on agricultural sites; commercial, institutional and industrial sites; and for domestic use in and around homes (i.e., resin strips). DDVP is used preplant in mushroom houses, and postharvest in storage areas for bulk, packaged and bagged raw and processed agricultural commodities, food manufacturing/processing plants, animal premises, and non-food areas of food-handling establishments. It is also registered for direct dermal pour-on treatment of cattle and poultry, and swine. DDVP is not registered for direct use on any field grown commodities. In letters dated March 2, 2007 and March 8, 2007, Amvac Chemical Corporation requested EPA to amend to terminate uses of pesticide product registrations ( printed page 13788) identified in this notice (Table 1). Specifically, the request would terminate DDVP use in dry bait formulations and in impregnated resin cat and dog flea collars. The request would not terminate the last DDVP products registered for use in the U.S.

III. What Action is the Agency Taking?

This notice announces receipt by EPA of a request from a registrant to amend to terminate uses of DDVP 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 DDVP registrant has 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 amending the affected registrations.

Table 2 of this unit includes the name and address of record for the registrant of the products listed in Table 1 of this unit.

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 Dichlorvos (DDVP).

Registrants who choose to withdraw a request for cancellation must submit such withdrawal in writing to the person listed under FOR FURTHER INFORMATION CONTACT . Such withdrawal must be received on or before April 23, 2007. 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. ( printed page 13789)

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. Amvac has indicated that there are no existing stocks of the products identified in Table 1; therefore, the Agency proposes to include the following provisions for the treatment of existing stocks of the products identified or referenced in Table 1: The prohibition on sales, distribution and use, except for proper disposal or export consistent with the requirements of section 17 of FIFRA, is effective immediately.
