reserve program.

o Syngenta indicated that they were working with the other atrazine technical registrants

to capture all the use sites, use patterns, and maximum rates on their end

‐ use products.

o Syngenta provided a draft atrazine use site matrix which includes application sites and

parameters.

adopting, sustainability, and plans to expand the program to other areas. PPT presentation

which specific BMPs and how many of each BMP have been implemented as a result of

stewardship/outreach program in 3 watersheds. (By 8/26/13 close of public comment

 Syngenta briefly provided input on topics for future discussion. Although time for this

discussion topic ran short, Syngenta’s Powerpoint slides include further details regarding

ongoing research and recent and pending atrazine publications.

o FOLLOW

‐ UP ITEM: EPA requests that as much as possible, registrants submit any

additional atrazine research, data, or information to be considered during registration

review during the current public comment period which ends on August 26, 2013. The

Atrazine Final Work Plan is currently scheduled for November 2013, and after that work

on the preliminary risk assessments will begin promptly since EPA does not anticipate

issuing a data call

‐ in notice. (Submit any additional research, data, and information by

December 2013)

### Information Request

 EPA requests atrazine usage and sales data (in pounds, not dollars) for all agricultural and non

‐ agricultural use sites. Usage and sales information at the county level would be optimal, but

regional sales or usage data would also be helpful. Information on the non

‐ agricultural types of3 uses (forestry, turf, etc.) would be especially valuable. This information may help the Agency to

focus on areas of the country that experience highest atrazine usage.

o FOLLOW

‐ UP ITEM: As much as feasible, registrants will compile and submit existing

usage and sales data (in pounds). Note that this information may be considered by

registrants to be Confidential Business Information, and as such it should be submitted

to EPA through the appropriate mechanism. (By 8/26/13 close of public comment

period)
