Start Preamble


Environmental Protection Agency (EPA).




This notice announces EPA's order for the cancellation and/or amendments to terminate uses, voluntarily requested by the registrant and accepted by the Agency, of products containing the pesticides sodium dimethyldithiocarbamate and/or potassium dimethyldithiocarbamate, pursuant to section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended. This cancellation order follows a September 16, 2009 Federal Register Notice of Receipt of Requests from dimethyldithiocarbamate salts registrants to voluntarily cancel and/or amend to terminate uses of some of their dimethyldithiocarbamate salts product registrations. These are not the last dimethyldithiocarbamate salts products registered for use in the United States. In the September 16, 2009 notice, EPA indicated that it would issue an order implementing the cancellations and amendments to terminate uses, unless the Agency received substantive comments within the 180-day comment period that would merit its further review of these requests, or unless the registrant withdrew its requests within this period. The Agency did not receive any comments on the notice. Further, the registrant did not withdraw its requests. Accordingly, EPA hereby issues in this notice a cancellation order granting the requested product cancellation and amendments to terminate uses. Any distribution, sale, or use of the sodium dimethyldithiocarbamate and potassium dimethyldithiocarbamate products subject to this cancellation order is permitted only in accordance with the terms of this order, including any existing stocks provisions.


The cancellations are effective April 21, 2010.
