Dear Ms. Tatinclaux:


Subject:  Docket ID Number EPA-HQ-OPP-2009-1017
          Federal Register Notice Vol 75 (217):  69073-69078
          Request to Withdraw Cancellation of Sodium Tetrathiocarbonate Products, 
          EPA Reg No. 66330-63 & 66330-69


Arysta LifeScience North America, LLC (Arysta) submitted a voluntary request to cancel two sodium tetrathiocarbonate containing products  -  Enzone (66330-69) and ETK-1101 (66330-63) on July 14, 2010.  Since that time, we have been approached by one of our customers to purchase from Arysta the sodium tetrathiocarbonate registrations.  We are currently negotiating the terms of such a purchase under which Arysta would transfer all obligations and rights for our sodium tetrathiocarbonate product.  They would be responsible for conducting the outstanding studies as identified in the March 30, 2010 EPA Data-Call-In (DCI) and all future required maintenance.    Consequently, we are requesting a withdrawal of our previous request to cancel the product registrations and request a time extension of 90 days to submit protocols with a 90 days extension to the end date for submission of final studies.

   
Should you have any questions or comments pertaining to Arysta's sodium tetrathiocarbonate products, please feel free to contact me via email at rodney.akers@arystalifescience.com  or via phone at 919-678-4922.

Regards,
