To-date, however, there have been no exceedences of this lev el of concern, so this specific provision of the MOA has not yet come into play.

Melanie, When is the "study submission" submitted t ypically? Ellis -----Original Message----- From: Biscoe.Melanie@epamail.epa.gov [mailto:Biscoe.Melanie@epamail.epa.gov] Sent: Thursday, August 19, 2010 5:08 PM To: Jacobs, Ellis Subject: RE: Atrazine /AMP data Hi Ellis, As established by the 2003 Memorandum of Agreement between EPA and Syngenta, one year's AMP (and SMP) data is due to t he Agency on January 31 of the following year. However, we typically re ceive these data as a study submission (in hard copy and as a PDF) and th en in subsequent weeks Syngenta sends the data in an excel spreadshe et. We received the spreadsheets containing the 2009 data on March 3 of 2010. At the present time, I would anticipate that the 2010 data you requested would be available any time between the end of January an d early March of 2011. If we do receive 2010 data at an earlier tim e, however, I will let you know and provide the data that you requeste d.Best Regards ,

Melanie, I've been looking at the AMP data for Ohio . The data I'm looking at runs through the end of 2009. Is more r ecent data available? I don't need the full data set for 2010, just the d ata for three Ohio towns- Blanchester, McClure Water treatment plant, and Piqua (Swift Run Lake and finished). Thanks.
