Discussion Topics & Follow‐up Actions

 Attendee introductions

 EPA provided an overview of the registration review process and timeline for atrazine.  EPA

highlighted that the registration review PWP does not include any anticipated data

requirements for atrazine nor issuance of a data call‐in notice.  The projected registration review

timeline reflects that.

o June 26, 2013 – Atrazine registration review docket opened

o August 26, 2013 – Close of 60‐day public comment period

o November 2013 – Anticipated Atrazine Final Work Plan completion date
2

o April to June 2015 – Anticipated posting of registration review draft risk assessments to

the docket for a 60‐day public comment period

 EPA requested clarification regarding the full list of atrazine agricultural and non‐agricultural use

sites, especially non‐agricultural use sites such as fallow, hay, pasture, forests, turf, conservation

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.

o FOLLOW‐UP ITEM:  EPA to review and provide input on type of data included in draft

use site matrix.  EPA will suggest any additional column headers and data that we think

should be included.  (By 8/12/13)

o FOLLOW‐UP ITEM:  Registrants will provide a complete atrazine use matrix.  (By mid‐

October 2013)

 Syngetna and partners provided a brief overview of stewardship programs in 3 watersheds (MO‐

01, MO‐02, NE‐04), including discussion of grower participation, which BMPs the growers are

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

available.

o FOLLOW‐UP ITEM:  Registrants will provide quantitative information, as available, on

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

period)

 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)

o FOLLOW‐UP ITEM:   EPA requests registrants provide a summary of the updated PBPK

model OR confirm that the materials provided at a previous atrazine meeting held on

February 10, 2011 are still accurate.  (By 8/26/13 close of public comment period)

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 of
3

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)
