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 amend two tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione product registrations to terminate or delete one or more uses. The request would delete tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione use in or on air washer systems; eating establishments; hospitals and related institutions; commercial institutions; institutional and industrial areas/premises; swimming pool water systems; household or domestic dwelling contents; evaporated condenser water systems; irrigation systems; and metal working fluids. The request would not terminate the last tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione 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 its request. If this request is granted, any sale, distribution, or use of products listed in this notice will be permitted after the uses are deleted only if the sale, distribution, or use is consistent with the terms as described in the final order.

DATES:

Comments must be received on or before October 12, 2010.

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 Verichem, Inc., to delete certain uses of tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione product registrations. In letters dated April 29, 2009, October 6, 2009, and July 8, 2010, Verichem, Inc., requested EPA to amend to delete certain uses of pesticide product registrations identified in Table 1 of Unit III.

III. What Action is the Agency Taking?

This notice announces receipt by EPA of a request from Verichem, Inc., to delete certain uses of tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione product registrations. The affected products are identified in Tables 1 and 2 of this unit.

Unless a request is withdrawn by the registrant or if the Agency determines that there are substantive comments that warrant further review of this request, EPA intends to issue an order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

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, FIFRA section 6(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.

The tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione registrant has requested that EPA waive the 180-day comment period. Accordingly, EPA will provide a 30-day comment period on the proposed requests.

V. Procedures for Withdrawal of Request

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 have been subjected 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 were packaged, labeled, and released for shipment prior to the effective date of the action. If the request for amendments to delete uses is granted, the Agency intends to publish the cancellation order in the Federal Register.

In any order issued in response to this request for an amendment to delete uses, EPA proposes to include the following provisions for the treatment of any existing stocks of the products listed in Table 1 of Unit III.

For voluntary product cancellations, registrants will be permitted to sell and distribute existing stocks of voluntarily canceled products for 1 year after the effective date of the cancellation which will be the date of publication of the cancellation order in the Federal Register. Thereafter, registrants will be prohibited from selling or distributing the products identified in Table 1 of Unit III., except for export consistent with FIFRA section 17 or for proper disposal.

Once EPA has approved product labels reflecting the requested amendments to delete uses, registrants will be permitted to sell or distribute products under the previously approved labeling for a period of 18 months after the date of Federal Register publication of the cancellation order, unless other restrictions have been imposed. Thereafter, registrants will be prohibited from selling or distributing the products whose labels include the deleted uses identified in Table 1 of Unit III., except for export consistent with FIFRA section 17 or for proper disposal.

Persons other than the registrant may sell, distribute, or use existing stocks of products whose labels include the deleted uses until supplies are exhausted, provided that the sale, distribution, or use is consistent with the terms of the previously approved labeling on, or that accompanied, the deleted uses.
