Tetrahydro-3, 5-dimethyl-2H-1, 3, 4-thiadiazine-2-thione; 
Amendment To Terminate and or Delete Certain Uses

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces EPA's order for the amendment to 
terminate and/or delete certain uses, voluntarily requested by the 
registrant and accepted by the Agency, of the products, listed in Table 
1, pursuant to section 6(f)(1) of the Federal Insecticide, Fungicide, 
and Rodenticide Act (FIFRA), as amended. This order follows a September 
10, 2010 Federal Register Notice of Receipt of Request from the 
registrant listed in Table 2 to voluntarily amend their tetrahydro-3, 
5-dimethyl-2H-1, 3, 4-thiadiazine-2-thione (Dazomet) product 
registrations to terminate or delete one or more uses. The request 
would terminate the uses listed in Table 1 of Unit II. The request 
would delete the uses listed in Table 2 of Unit II. The request would 
not terminate the last tetrahydro-3, 5-dimethyl-2H-1, 3, 4-thiadiazine-
2-thione products registered for use in the United States and would 
result in retention of some registered uses for those products. In the 
September 10, 2010 notice, EPA indicated that it would issue an order 
implementing the amendments to terminate uses, unless the Agency 
received substantive comments within the 30-day comment period that 
would merit its further review of these requests, or unless the 
registrant withdrew their request within this period. The Agency did 
not receive any comments on the notice. Further, the registrant did not 
withdraw their request. Accordingly, EPA hereby issues in this notice a 
cancellation order granting the requested amendment to terminate uses. 
Any distribution, sale, or use of the products subject to this 
cancellation order is permitted only in accordance with the terms of 
this order, including any existing stocks provisions.

DATES: The order is effective December 20, 2010.

III. Summary of Public Comments Received and Agency Response to 
Comments

    During the public comment period provided, EPA received no comments 
in response to the September 10, 2010 Federal Register notice (75 FR 
55327) announcing the Agency's receipt of the request to voluntarily 
amend registrations to terminate certain uses of products listed in 
Table 1.

IV. Cancellation Order

    Pursuant to FIFRA section 6(f), EPA hereby approves the requested 
amendment to terminate uses of tetrahydro-3, 5-dimethyl-2H-1,3,4-
thiadiazine-2-thione registrations identified in Table 1 of Unit II and 
delete uses of tetrahydro-3, 5-dimethyl-2H-1,3,4-thiadiazine-2-thione 
registrations identified in Table 2 of Unit II. Accordingly, the Agency 
orders that the product registrations identified in Table 1 of Unit II 
are hereby amended to terminate the affected uses, also listed in Table 
1. Any distribution, sale, or use of existing stocks of the products 
identified in Table 1 of Unit II. in a manner inconsistent with any of 
the Provisions for Disposition of Existing Stocks set forth in Unit VI. 
will be considered a violation of FIFRA.

V. 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.

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 
action. The existing stocks provision for the products subject to this 
order is as follows.
    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 II., 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 such sale, distribution, or use 
is consistent with the terms of the previously approved labeling on, or 
that accompanied, products bearing the deleted uses.
