Dear Rashmi Sahai,

Thanks for your request. I'll be working in conjunction with Janet

Bressant in our FOIA office to provide the information you requested.

To receive the information, you will have to submit a form, which Janet

will describe in more detail.

Depending on the nature of (some of) the data, it may take some time to

get it to you. In the mean time, we do have Community Water System data

from 2003, 2004 and 2005 posted to the EPA website at:

http://www.epa.gov/pesticides/reregistration/atrazine/ under "Atrazine

Updates" and "Pesticide Program's Monitoring in Community Water Systems

." Do note that the information on the website is approximately 1 year

old-- we are currently working to update the website.

 Subject: Request for Data from Syngenta Atrazine Monitoring Program

Dear Melanie Biscoe,

I am emailing you to request any data that the EPA has received

regarding Syngenta's Atrazine Monitoring Program, including their

Rural Well, Ecological, Watershed, Sugarcane, and Estuary Monitoring

Programs. I have already received the 2003 Atrazine Monitoring Program

Report and am looking for any other monitoring data from any other

year (hopefully in electronic format). My mailing address is: 3110

Main Street, Suite 205, Santa Monica, CA 90405-5353.

Thank you very much. Have a good day!

Sincerely,

Dear Rashmi,

Attached are the files we have from the Atrazine Monitoring Program for

Community Water Systems for the official years of the program, 2003

through 2008.

Years 2003 and 2004 do not contain simazine data. The remaining years
(from the latter half of 2005 on) contain data for all triazine

residues.

These files contain the results for all of the 120+ to 140+ Community

Water Systems that were monitored over the 6-year period. The request

for data covered 34 systems. For 10-12 of these systems listed below,

there were little to no data submitted after 2003. This is because (in

a rare case or two) they did not agree to enter the monitoring program

or because they began purchasing water from another neighboring

Community Water Systems. The systems in this request for which we have

little to no Atrazine Monitoring Program data are the following:

Sorento, IL; White Hall, IL; Hettick, IL; Shipman, IL; Louisville, IL;

Omaha, IL; Holland, IN; Scottsburg, IN; Sardinia, OH; Clermont Co, OH;

and Williamsburg, OH

The attached files contain data for the remaining systems in the request

as well as for all Community Water Systems which entered the Atrazine

Monitoring Program in 2003 and subsequent years.

I'm currently working on collecting the additional data you requested,

and can hopefully provide it to you within the next two weeks.

Dear Nicolai,

Thanks very much for your email. In fact there are regular atrazine monitoring programs in the US that 

focus primarily on surface water and drinking water. 

Atrazine Ecomonitoring

Through EPA's reregistration process for atrazine, EPA required that atrazine registrants conduct 

monitoring in 40 watersheds representative of the most vulnerable watersheds associated with corn and 

sorghum production. EPA presented results from this monitoring, as well as implications for watersheds 

in other areas of the midwestern US, to the FIFRA Scientific Advisory Panel (SAP) in May 2009. You can 

find details regarding the monitoring results at the docket for the May SAP Meeting : docket number 

EPA-HQ-OPP-2009-0104 at http://www.regulations.gov. For your convenience, I'm attaching EPA's White 

Paper and an addendum to the White Paper.

State Ecomonitoring Programs

There are several states that monitor for atrazine in water bodies. I have a few web links to monitoring 

that is being conducted on the Big Blue River in Nebraska (see below). If I come across any links for work 

in other states, I will email you those as well.

http://blueriver.unl.edu/projects/monitor/joint.htm

http://conservationbuffers.unl.edu/unlprojects.htm

http://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/5316/report/0

Drinking Water Monitoring

Through EPA's reregistration process for atrazine, EPA has also required that atrazine registrants conduct 

intensive monitoring in Community Water Systems (CWS) across the US that have annual average total 

chlorotriazine levels at or above 2.6 ppb (averages are, generally, based on four quarterly samples of data 

collected under the Safe Drinking Water Act). The intensive monitoring is conducted weekly during the 

growing season and biweekly the rest of the year. You can find out more about this monitoring program 

and view some of the data from this program at EPA's atrazine website: 

http://www.epa.gov/pesticides/reregistration/atrazine/. This summer EPA is updating its atrazine website, 

so more recent data will also be available soon.

Note that, on the atrazine website, there is also a link to EPA's Office of Water, which oversees state 

implementation of Safe Drinking Water Act (SDWA) monitoring. The Office of Water website has data 

regarding SDWA violations (atrazine levels > 3.0 ppb) for individual water systems in the US.

I hope this helps. Feel free to contact me if you have additional questions.

Hello Ms. Biscoe,

I received your name from Janet Bressant in regards to a request for documents I made to her last 

week. From her, I received Atrazine Community Water System Data spreadsheets for 2003 to 2008. This 

is the HQ-RIN 1692-09 request. 

Subsequently, I asked if she could help me find the Atrazine Community Water System Data 

spreadsheets from 1993 to 2001. I mis-typed in the email and requested 1998 instead of 1993. Since 

you are handling the request now, I wanted you to have the updated information. I need 1993 – 2001.

I appreciate any help you can offer in this situation.

No problem--I had chatted with Eric Burneson of OGWDW yesterday and we both 

commiserated that your office must be swamped.

So I am not trying to add more and there is no real rush on this briefing but 

as you can see if you flip to the last page of the enclosed comments from 2006 

(it's been while since we have had a triazine issue to comment on), we have 

done a fair amount of research on atrazine so I just want to keep updated.

Melanie,

Attached is the slide set for the meeting in MO on the 12th. We have worked 

hard to get Kickapoo to submit samples; they committed to start sending 

samples as scheduled during the last visit made by Todd Barlow. We are 

keeping an eye on this and will let you know if we continue to have issues 

receiving samples.
Thanks

Subject: Atrazine - Nov. 12 Meeting in MO and Kickapoo Tribe

Hi Dan,

(1) What is the agenda for the Nov. 12 stakeholder meeting in MO?

(2) Kickapoo Tribe recently contacted Region 7 about wanting

monitoring of its water system. You had indicated a while back that it

was difficult to get access to the system. Is that still the case?

What is the status, and does Region 7 or OPP need to help in some way

for you to gain access?

Thanks,

Subject: Atrazine: Stakeholder Conference Call on Informing the Public about Drinking Water Monitoring 

Results

Dear Atrazine Stakeholders,

OPP indicated in its previous conference call with you (on the human health re-evaluation of atrazine) that 
we would be interested in working with you to explore better ways to inform the public more quickly about

results of atrazine drinking water monitoring.

We would like to have a conference call discussion with you all on this topic sometime in the next three 

weeks. Please email me with information on days and times that would (or would not) work well for you, 

and I will try to find a place in the schedule that works well for all of us .

Thanks very much and I look forward to our discussion.

Best Regards,

Subject: RE: Atrazine: Frequency of Monitoring Followup (Peaks)

Melanie -

Enclosed is requested slide set.

For the question about the "replacement" sampling (from Wenlin):

The primary reason required for replacement in the bootstrap sampling 

algorithm is to maintain the original statistical structure unchanged 

(variability and distribution) in each of the bootstrap samples comparing to 

the original sample. See reference: Efron, B., and R.J. Tibshirani.1993. (An 

Introduction to the Bootstrap. Chapman & Hall/CRC). With replacement sampling, 

the same value can be re-sampled many times with the same probability each 

time a bootstrap simulation is executed. Efron showed by random sampling with 

replacement, the variability captured in the bootstrap samples can best 

represent the original sample and its associated population. 

Thanks

Dan

Subject: Atrazine: Frequency of Monitoring Followup (Peaks)

Hi Dan,

Would it be possible to get the slides from last week's presentation

today (even if the raw data can't be sent)? That would be really

helpful to our team. Just let me know - thanks!

Also, I think the main question we had from last week's meeting was,

what was the justification for putting individuals back in the

population before sampling again? I guess we're not sure what added

value that provides as opposed to just sampling from the population

without replacement. If you all can provide some insight on that, it

would be helpful. We're going to have an internal meeting as follow-up

to your presentation and perhaps come up with other questions, but this

is the primary one that has been brought up.

Hi Dan,

Can you all send the 2009 AMP data? I believe it was due on Jan 31st,

but I'm sure trying to get other submissions in for SAPs was totally

swamping you. If you can send the data in spreadsheet form, as usual,

and of course if you can send the report as well, that'd be great.

Hi Dan,

In preparation for the September 2010 Atrazine SAP, OPP would like to have a list of the studies (that is, 

studies that are tox-related or drinking-water-monitoring-related) that Syngenta has done or is currently 

doing and would submit by July. 

For each study, it would be helpful if we could have a 2-3 sentence description of the study with 

approximate dates by which you would send us data and/or reports. 

Also, based on our recent conversations, it is our understanding that Syngenta will send OPP its new 

hormone data as it comes in during the spring and summer - please confirm that this is the case.

Thanks and look forward to hearing from you on this,

Melanie,

We support the one-stop shop principal you reference. If the EPA approved 

labels are requiring users to go to this web site that Syngenta maintains, 

then to have the user just be rerouted to their State controlling agency seems 

to be cumbersome and encouraging a skipped step. We would prefer that, for 

Wisconsin, Syngenta put a link to our atrazine web information right on their 

web site.

Excellent question Stan - I am really glad you asked about this, because this 

could be a serious issue...

Syngenta maintains the hotline, but their information (as far as I've been 

aware) pertains to EPA as opposed to State prohibitions of atrazine in 

watersheds. Clearly for Wisconsin this is a problem! (And potentially for 

other states too, I'll have to get in touch with the regions on this). It may 

be as simple as Syngenta adding language to the message clarifying on the 

website and the hotline that atrazine users should contact their states to be 

aware of any additional state restrictions. Of course the best thing to do 

for the user would be to have one-stop-shopping on the AWIC and the hotline, 

streamlining both EPA and State prohibition info.

Lets work on this - I'll notify my management of the issue and we'll see what 
we can do. I know growing season is here, so I would hope we could get a good

solution quickly!

Have a good weekend and lets be in touch!

Hi Nancy, can you tell me a little more about this "atrazine-watershed.info" 

site? Who owns and maintains it?

The hotline phone number listed on the web site has been disconnected.

It appears all labels for atrazine-containing products direct all users to go 

to this web site for more information on watersheds where use of atrazine is 

prohibited. As you can see, it provides no such information, because, 

atrazine has not exceeded EPA OPP drinking water levels of concern in any 

watershed within the Uninted States.

"Therefore, no related atrazine prohibitions are currently in effect."

Then, it refers the individual back to the label to view "any local 

restrictions".

Pretty misleading at the least.

I'm also wondering how Wisconsin can update their records to show all of our 

atrazine prohibition areas.

Hi Stan,

Apologies for the delayed response on this. The Atrazine Hotline has been restored and no longer says 

"Atrazine Hotline is unavailable." 

With regard to Wisconsin's information on prohibition of atrazine use in selected watersheds , EPA 

recommends that you contact Syngenta directly (or vice versa) about that request, as there currently is no 

requirement in EPA's Memorandum of Agreement with Syngenta that requires Syngenta to post state 

restrictions. I've contacted Syngenta about your concern and provided your information so their state rep 

can contact you directly. Feel free also to call Dan Campbell in Syngenta's Regulatory Affairs office. His 
contact information is dan.campbell@syngenta.com and his phone number is 1-336-632-7627.

If you need anything additional from EPA concerning atrazine, feel free to email or call me any time.

Subject: Atrazine CWS Monitoring Program Follow-up

Dear Mr. Jacobs,

As discussed during our Monday call, I'm attaching some information on the Atrazine Monitoring Program 

you have requested. 

(1) Listed below are the 26 monitoring sites that have been added to the AMP since 2003. None of these 

CWS are in Ohio.
(2) I am also attaching a study that EPA conducted in 2001 that reviews atrazine CWS data from 

1993-1998, which you may find helpful. The main body of the report is attached here and I will send the 

appendices in separate emails, as there are several and they are sizeable. 

(3) CWS atrazine data EPA received from 1999-2002 was received at various times through various 

divisions in the Office of Pesticide Programs and , unlike the data on the website or in the 2001 study, are 

currently not consolidated in a manner that is conducive to public distribution . These data would take 

some time to organize and prepare. Additionally, some of these data may have been voluntarily provided 

by the registrant (i.e., not required by EPA) and, as a result, may be considered confidential business 

information that would not be made available to the public. If you feel as though the data for this time 

period is critical to your work, let me know and I can get an estimate of the timeframe we'd need to tease 

through these data.

(4) During our conversation, you requested that EPA provide you with re-arranged Ohio-only AMP data. 

EPA will not be able to provide you with re-arranged data. However, if you need the AMP data currently 

posted on the website in another format (e.g. pdf if your computer does not support MS Excel), we would 

be happy to provide that.

Thanks very much for your interest in the Atrazine Monitoring Program . If you have any additional 

questions, feel free to email or call.

MO DNR News Release:

http://www.dnr.mo.gov/newsrel/nr10-375.htm

News Release 375 

High levels of atrazine detected in Drexel drinking water

Volume 38-375 Contact: Judd Slivka 

(For immediate release) 573-751-1010 / 573-291-3053 (after hours) 

JEFFERSON CITY, MO, JUNE 23, 2010—High levels of the herbicide atrazine have been found in the city 

of Drexel’s public water supply, the Missouri Department of Natural Resources announced today. 

The maximum contaminant level for atrazine is 3 parts per billion. The amount of atrazine found in the 

most recent routine quarterly sample analyzed by the Missouri Department of Natural Resources 

laboratory was 31.2 parts per billion. The department is investigating the cause for this recent spike in 

atrazine levels and will be retesting the water and working closely with the community. 

While this level is above the maximum contaminant level set by the U.S. Environmental Protection 

Agency, that level is set based on long-term exposure. The Department of Health and Senior Services 

does not expect to see any significant acute health effects as a result of this monitoring spike. The 

Missouri Department of Health and Senior Services recommends neither using the water for drinking nor 

using it to cook, wash dishes or to make ice. 

Public water supply systems are required to test for chemicals four times per year. Atrazine and other 

chemical levels are tracked using a running annual average. This single spike in atrazine levels 

immediately puts the water system in non-compliance.
The Missouri Department of Natural Resources has been working with the Drexel Public Water Supply on 

compliance issues for several years. The Drexel water system is currently constructing a connection to 

the Tri-County Water Authority in Independence. The water system has signed an agreement to begin 

purchasing water from Tri-County by the end of the year. 

Atrazine is a common herbicide used to control broadleaf and grassy weeds. Atrazine is mainly applied to 

corn and soybean crops, but is also used on sorghum, sugarcane and Christmas tree farms.

For more information, call the Department of Natural Resources’ Public Drinking Water Branch at 

800-361-4827 or 573-751-5331.

High Levels of Atrazine Detected in Drexel Drinking Water

Atrazine makes water supply unusable in 

Drexel, Mo.

Authorities are warning Drexel, Mo., residents not to drink the water there after routine testing 

revealed high levels of the herbicide atrazine.

The Missouri Department of Natural Resources is investigating the cause of the spike and will be 

re-testing the water, according to today’s announcement. In the meantime, residents should not use 

Drexel’s public water supply to drink, cook, wash dishes or make ice — not even if the water is 

boiled.

While the atrazine level was more than 10 times the maximum amount set by the U.S. Environmental 

Protection Agency, that level is based on long-term exposure.

“At this point we don’t think there should be any negative health effects from a brief exposure,” said 

Kit Wagar, spokesman for the Missouri Department of Health and Senior Services.

Dear Mr. Jacobs,

Thanks for your email. For information on water systems that have or

have had SDWA violations, OPP would refer you Ron Bergman in EPA's

Office of Water, who can be contacted at bergman.ronald@epa.gov,

202-564-8323. OW's Web site may also be of help:

http://www.epa.gov/safewater/index.html

Additionally, OPP's current understanding is that SDWA violations cannot

result from AMP monitoring, as SDWA violations must be based on

monitoring data collected specifically under SDWA and not from any other

monitoring programs. It may be helpful to you to clarify that

requirement with Ron Bergman in OW.

Hi Ellis,

As established by the 2003 Memorandum of Agreement between EPA and

Syngenta, one year's AMP (and SMP) data is due to the Agency on January

31 of the following year. However, we typically receive these data as a

study submission (in hard copy and as a PDF) and then in subsequent

weeks Syngenta sends the data in an excel spreadsheet. 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 and early March of

2011. If we do receive 2010 data at an earlier time, however, I will

let you know and provide the data that you requested.

Subject: Re: Definition of 90-day rolling average

Helen,

Helen,

With regard to your previous email and your first question below (answer to your second question below 

will be sent separately):

The method you described in your email is correct. A 90-day rolling average (or any rolling average) is 

the average of concentrations over consecutive 90-day periods, beginning from day 1 through day 90 and 

then shifting the averaging window by 1 day until you've moved through the entire year of data.

What might complicate things is how you estimate concentrations for days in between sampling days 

(that's one of the topics of EPA's last 2 Scientific Advisory Panels). What OPP is doing now is assigning 

the last measured concentration to all subsequent days until the next measurement (stairstep approach) 
and then calculating the rolling average. (Other ways include averaging only the measured values that

occur within the 90-day window or linearly interpolating between sample points ). 

I hope this helps.

1) Since testing is done weekly or biweekly (and not every day) how does the EPA calculate a 

90-day rolling average? For a water provider who has quarterly samples, how does EPA 

calculate a 90-day rolling average?

2) How does EPA calculate an annual average and multi-year average?

Thank again - I look forward to hearing from you.

Hi Melanie,

Thank you very much for the clarification. I originally assumed that EPA averaged only 

measured values during a 90-day window, so I'm glad I asked to clarify. You mentioned this 

topic was discussed at the last two Scientific Advisory Panel meetings -- what steps, studies, or 

thought processes did EPA take to formally adopt this stair step averaging approach? 

In addition to that question, I would like to follow up on a FOIA request I sent to you months ago 

regarding the raw analytical data for AMP. I am interested in obtaining all raw analytical data 

from the lab instruments regarding the water samples taken as part of the Atrazine Monitoring 

Program. Does EPA have this information? If it will help, I can submit another official request 

through the EPA FOIA form, but I thought I would check with you first. I look forward to 

hearing from you regarding this.

Hi Helen,

To clarify on Questions 1 and 2:

(1) See my previous email on calculating the 90-day rolling average in

OPP's Atrazine Monitoring Program (AMP). There are no water providers

in the AMP that only take quarterly samples. Quarterly samples are

taken as part of data collection under the Safe Drinking Water Act

(SDWA), however.

(2) Similarly, annual average and multi-year averages are not calculated

from AMP data, as the AMP is intended to monitor for intermediate-term

exposures. If you are interested in data collection and calculation of

annual averages under SDWA, OPP would refer you Ron Bergman in EPA's

Office of Water, who can be contacted at bergman.ronald@epa.gov,

Subject: Atrazine: Well Vulnerability Study

Dan,

We talked about this a little while back - for some reason Syngenta's Well Vulnerability study has gone 

into the EPA void (at least as far as I can tell). I recall you weren't aware of this study when we talked 

about it, but Paul Hendley should know it intimately. Syngenta submitted a proposal to do this study on 

November 9, 2004. EPA sent a letter accepting the proposal December 29, 2004. On September 19, 

2006, Paul Hendley, Chris Harbourt, and Paul Miller gave a presentation to EPA called "Atrazine Rural 

Well MOA Update." I imagine it was around that time that you all submitted the Well Vulnerability Study . 

If there is an electronic copy Syngenta has that could be forwarded to me, that would be ideal.

Thanks very much,

Dan,

(1) As follow-up to the SAP, EPA requests that Syngenta provide studies 1-3 listed on slide 4 of Dr. Kim's 

presentation. Particularly, we would like, as soon as possible, Study 1 entitled "An oral (gavage and 

dietary) study evaluating the pharmacokinetics of atrazine in female Sprague -Dawley rats" (WIL-639081, 

WIL Research Laboratories & Covance Laboratories). Please let me know when we could receive these 
studies.

(2) Also, last week I asked about the Well Vulnerability Study and whether that could be resubmitted . 

Please provide this as soon as possible.

We'll likely be asking for additional data /documents, so there will be more emails/requests to come over 

the following weeks!

Subject: Information on new WHO standard

Melanie – 

Wanted to forward you the enclosed documents and link to the World Health Organization’s recent 

revision of the drinking water guideline values from 2 ppb to 100 ppb for atrazine + chlorometabolites. 

WHO also has set a drinking water guideline value of 200 ppb for hydroxyatrazine. The WHO 

documents are from the following link: 

http://www.who.int/water_sanitation_health/dwq/chemicals/atrazine/en/

Note that the new WHO value, based upon the 1.8 mg/kg/day endpoint, compares well to other values 

set worldwide, including Australia (Health Value of 40 ppb), Canada (chronic drinking water level of 

concern of 41.9 ppb, guideline value of 5 ppb), and the recent Drinking Water Levels of Comparison 

determined by EPA in the 2006 RED (ranging from 12.5 to 68 ppb). The European Union in 1996 had 

proposed Maximum Allowable Concentration (MAC) of atrazine in water of 15 ppb. The United States, 

as you know, has the MCL of 3 ppb, based upon the historic endpoint of 0.5 mg/kg/day from 1991.

Thanks!

Subject: Re: Definition of 90-day rolling average

Hi Helen,

Thanks for your email. Our Ecological Fate and Effects Division in OPP indicated that it has calculated 

90-day rolling averages using both stair-step interpolation as well as linear interpolation to provide values 

for the days in between the weekly collected samples, and that the two methods do not give substantially 

different answers, in general. Because so few of the maximum 90-day averages have been anywhere 

near the current 90-day level of concern, the interpolation method has never really been an issue. The 

SAP has not given us a recommendation for either method, and it is something we are still looking at 

currently. When in doubt, EPA chooses the more protective result. Generally, the stair-step approach 

provides the more protective result when calculating the 90-day average.

EPA does not currently receive the lab instrument readings prior to QA /QC processes Syngenta and its 

labs conduct under the AMP.

If you have any additional questions, just let me know.

Nancy,

I hope that this finds you well. Sorry for being an intermittent

correspondent these past months. We, CSIRO, have been very busy with the

bioremediation technology that I presented in Savannah earlier this

year.

Please find attached an recent peer reviewed publication we have around

our triazine technology. Furthermore, I attach an updated overview that

I gave at a recent (biotech) conference in DC. We have had no recent

public announcements per se, but are hoping that things we are working

on now will be in the media later this year. I have very early plans to

be in San Antonio, but there is a lot of water yet to pass under that

bridge before those plans are finalized.

I understand that there are some deliberations underway (from a water

quality perspective) around triazines and would be curious to get any

insights from you around the process and current tenor of thinking about

what is to be proscribed from a regulatory perspective - I am finding

Rick and Jeff,

BEAD indicated that they didn't have any specific questions for you all, but wanted to learn more about 

Wisconsin's atrazine prohibition areas and what the impact has been on groundwater as well as growers .

I have a few specific questions, though, following up on that:

Prohibition Areas

 How are growers adapting in prohibition areas? Are they switching to alternative chemistries, and is 

that having any sort of adverse impact on the environment? Are they dropping corn and sorghum in 

favor of other crops?

 Does anyone know/has anyone studied what the economic impact has been on growers in the 

prohibition areas?

 Has anyone studied the environmental impact of prohibiting atrazine in these areas (compared with 

areas where atrazine is not prohibited)?

 Have there been any initiatives to mitigate for atrazine in the areas proposed for prohibition PRIOR to 

the actual prohibition (in order to avoid it)? If so, what did these initiatives involve? Have any 

mitigation activities resulted in a reversal of the preliminary decision to prohibit atrazine use in an 

area?

Rate Reductions

 Are the rate reductions required for Wisconsin efficacious (0.75 lb/acre on coarse soils in particular)? 

Are there any data on the efficacy?

 What has been the impact on growers of rate reductions (cost-wise)? 

 Are growers switching to alternative chemistries , and is that having any sort of adverse impact on the 

environment? Are they dropping corn and sorghum in favor of other crops?

 Has anyone studied the environmental impact of reducing the application rate on coarse soils ?

Other

 When Wisconsin initially proposed instituting prohibition areas and rate reductions , what was the 

response from stakeholders?

 How does Wisconsin enforce these lower rates and the prohibition areas ? How big of a problem is 

compliance?

 Do any of the areas where groundwater is a concern overlap with 303d listings? Is the groundwater 

protection ever linked with efforts to reduce atrazine in "impaired waters"? If so, how?

 With regard to groundwater concerns... are the main concerns consumption of groundwater through 

private wells or public systems that rely on groundwater ? Do you all think that well construction is a 

primary contributor to exposure in some areas, or is the application rate the primary factor?

If I think of anything else, I'll let you know. Look forward to talking with you both on the 29th,

Hi Rick and Jeff.

It's getting a little hairy with the meetings for folks this week, so moving 

the time around has some issues. Plus, I found out a few of the key staff are 

out of the office until tomorrow, and wouldn't be able to provide questions 

ahead of time.

Given the scheduling/question issues, would it work to move this call to the 

week after Thanksgiving? The 29th or 30th look particularly open.

Just let me know if either day would work for you.

Look forward to hearing from you,

If that doesn't work for you, it will still work for the earlier time, but 

Jeff Postle may have to have the discussion without me, or I may arrive late. 

Let us know. Also, were you going to send along some questions you would like

Hi Melanie,

November 17 would work OK for Rick and I. For us anytime after 11 AM and 

finishing by 2 PM Wisconsin time would work. November 18 might also work but 

I would have to join the conference call from another location as I am not in 

the office that day. Also, if you could provide at least a general idea of 

your questions in advance that would be great. I was here back in those days 

but it was almost 20 years ago when we first started restricting atrazine and 

I would like to refresh my memory a bit.

Rick and Jeff,

I'm EPA's Office of Pesticide Programs Chemical Review Manager for atrazine. 

I and some of my colleagues in OPP are interested in learning more about the 

initial creation Wisconsin's atrazine use restriction areas and issues raised 

regarding those restrictions.

Would both of you be available for a conference call Wednesday or

Thursday of next week (Nov. 17 or 18) for a discussion? Just let me

know at your convenience. (FYI I'm out of the office until Monday morning if 

you don't hear back from me until then!) If those days aren't convenient, 

just let me know what works for you.

Thanks and I look forward to talking with you both,

Subject: Re: FW: Update from CSIRO on pesticide remediation technology

Hi Cameron,

Thanks for your email and I apologize for the delayed response. Nancy talked to me about her 

conversation with you, and some time back I tried to call and leave a voicemail for you but I don 't think it 

got through.

Below I've included some information on EPA's current human health evaluation of atrazine, as 

well as some links to additional information about our regulation of atrazine . If you have any questions, 

please feel free to call or email me (it might be helpful to email regarding a time to call, however, because 

of the time difference).

In 2003, EPA re-registered atrazine, which was EPA's last major regulatory decision specifically 

for this herbicide. Given the new scientific information generated since the 2003 reregistration decision 

and the documented presence of atrazine in both drinking water sources and other bodies of water in the 

US, EPA is reviewing the new research to ensure that its regulatory decisions regarding atrazine are 

based on the best available science and protect public health and the environment .

This year, EPA held three FIFRA Scientific Advisory Panel (SAP) meetings on human health 

issues related to atrazine. These SAPs included atrazine research regarding toxicology and 

epidemiology. The SAP meetings ensure scientific soundness and integrity in the assessment of science 

issues associated with atrazine and provide EPA independent, outside scientific advice on these issues . 

The SAP itself is a peer review panel comprised of independent scientists who are experts in fields 

relevant to atrazine science. The SAP meetings are also open to the public, and EPA encourages 

interested parties to participate in these meetings. 

In February, EPA presented and sought scientific peer review of its proposed plan for 

incorporating epidemiology studies into the atrazine risk assessment . In April, EPA presented and sought 

scientific peer review of its evaluation of atrazine effects based on experimental laboratory studies that will 

inform the selection of endpoints and safety factors in the risk assessment , and the sampling design 

currently used to monitor drinking water in community water systems . In September, EPA presented and 

sought scientific peer review of its evaluation of atrazine non -cancer effects based on experimental 

laboratory studies and epidemiology studies. The September review was intended to include any new 

experimental laboratory data since the April SAP meeting. 

Through these SAPs, EPA presented and sought peer review of its evaluation of approximately 

120 toxicology studies and 25 epidemiology studies. If you are interested in reading EPA’s reviews of 

these studies, as well as meeting transcripts and the SAP’s recommendations to EPA on this research, 

see the Agency's 2010 SAP Meetings Web page, 

http://www.epa.gov/scipoly/sap/meetings/2010/index.html, which provides meeting minutes and 

transcripts when they become available.

In 2011, EPA plans to hold another peer review concerning findings of the Agricultural Health 

Study (http://aghealth.nci.nih.gov/) as well as epidemiology and laboratory animal studies on atrazine . At 

the conclusion of this evaluation of atrazine’s human health effects, EPA plans to ask the SAP to review 
atrazine’s potential effects on amphibians and aquatic ecosystems . As a result of the current atrazine

science evaluation, EPA plans to make any needed risk management decisions on atrazine consistent 

with the science and US statutes. 

For more information about the EPA Office of Pesticide Program's current regulatory requirements 

for atrazine, see the Office of Pesticides' Atrazine webpage at: 

http://www.epa.gov/pesticides/reregistration/atrazine/index.htm. For updates on EPA's activities that 

follow up on atrazine's 2003 reregistration, as well as updates on the current science evaluation of 

atrazine, see the Atrazine Updates website at: 

http://www.epa.gov/pesticides/reregistration/atrazine/atrazine_update.htm

I hope this information is helpful and again, if you have any questions just let me know. Also, I 

should note to you that any communications EPA receives on atrazine and drinking water are required to 

be placed in the public docket. I noticed Nancy also asked about that, but I just wanted to make sure that 

there would be no confidentiality issues in placing the presentation in the public docket . 

Thanks very much and I look forward to hearing from you.

By way of introduction, Nancy Fitz suggested that I get in contact with you 

following correspondence we have had around atrazine and the current and 

emerging regulatory outlook.

Please find attached a recent peer reviewed publication we have around our 

triazine technology. Furthermore, I attach an updated overview that

I gave at a recent (biotech) conference in DC.

I understand that there are some deliberations underway (from a water quality 

perspective) around triazines and would be curious to get any insights from 

you around the process and current tenor of thinking about what is to be 

proscribed from a regulatory perspective - I am finding hard to cut through

I would be pleased to catch up by phone if that is more convenient to discuss 

this matter.
Thanks in anticipation of your assistance.

Sorry for taking so long to get back to you! Last Friday I was writing

up some News updates for the TPSA web site and was getting ready to add

one with the information you sent me. But as I looked through the

information, I realized that the second page of the overview document

check with you to see if you wanted this posted on the TPSA web site

and, if so, if you could delete that page because it would certainly

raise a lot of questions.

Nancy,

I hope that this finds you well. Sorry for being an intermittent

correspondent these past months. We, CSIRO, have been very busy with the

bioremediation technology that I presented in Savannah earlier this

year.

Please find attached an recent peer reviewed publication we have around

our triazine technology. Furthermore, I attach an updated overview that

I gave at a recent (biotech) conference in DC. We have had no recent

public announcements per se, but are hoping that things we are working
on now will be in the media later this year. I have very early plans to

be in San Antonio, but there is a lot of water yet to pass under that

bridge before those plans are finalized.

I understand that there are some deliberations underway (from a water

quality perspective) around triazines and would be curious to get any

insights from you around the process and current tenor of thinking about

what is to be proscribed from a regulatory perspective - I am finding

hard to cut through the "noise" on the internet on this issue!

Hi Melanie,

We got your questions and hope to be able to address most of them in our 

conference call. In a couple of the questions you ask about the 

"environmental impact" of our regulations and I'm wondering if you could be 

more specific on what all you include under this term.

Thanks,

Rick and Jeff,

BEAD indicated that they didn't have any specific questions for you all, but 

wanted to learn more about Wisconsin's atrazine prohibition areas and what the 

impact has been on groundwater as well as growers.

I have a few specific questions, though, following up on that:

Prohibition Areas

 How are growers adapting in prohibition areas? Are they switching to

 alternative chemistries, and is that having any sort of adverse

 impact on the environment? Are they dropping corn and sorghum in

 favor of other crops?

 Does anyone know/has anyone studied what the economic impact has been

 on growers in the prohibition areas?

 Has anyone studied the environmental impact of prohibiting atrazine

 in these areas (compared with areas where atrazine is not

 prohibited)?

 Have there been any initiatives to mitigate for atrazine in the areas

 proposed for prohibition PRIOR to the actual prohibition (in order to

 avoid it)? If so, what did these initiatives involve? Have any

 mitigation activities resulted in a reversal of the preliminary

 decision to prohibit atrazine use in an area?

Rate Reductions

 Are the rate reductions required for Wisconsin efficacious (0.75

 lb/acre on coarse soils in particular)? Are there any data on the

 efficacy?

 What has been the impact on growers of rate reductions (cost-wise)?

 Are growers switching to alternative chemistries, and is that having

 any sort of adverse impact on the environment? Are they dropping

 corn and sorghum in favor of other crops?

 Has anyone studied the environmental impact of reducing the

 application rate on coarse soils?

Other

 When Wisconsin initially proposed instituting prohibition areas and

 rate reductions, what was the response from stakeholders?

 How does Wisconsin enforce these lower rates and the prohibition

 areas? How big of a problem is compliance?

 Do any of the areas where groundwater is a concern overlap with 303d

 listings? Is the groundwater protection ever linked with efforts to

 reduce atrazine in "impaired waters"? If so, how?

 With regard to groundwater concerns... are the main concerns

 consumption of groundwater through private wells or public systems

 that rely on groundwater? Do you all think that well construction is

 a primary contributor to exposure in some areas, or is the

 application rate the primary factor?

If I think of anything else, I'll let you know. Look forward to talking with 

you both on the 29th,

Hi Rick and Jeff.

It's getting a little hairy with the meetings for folks this week, so moving 

the time around has some issues. Plus, I found out a few of the key staff are 

out of the office until tomorrow, and wouldn't be able to provide questions 

ahead of time.

Just let me know if either day would work for you.

Hi Melanie,

Here is a report related to the atrazine prohibition areas in Wisconsin if you 

have time to take a look before our call. I may also send you some other 

reports related to atrazine in Wisconsin groundwater.

We are currently working on a survey with the USDA/National Agricultural 

Statistics Service on the impacts of atrazine prohibition areas on corn 

production and we will be able to share some of the preliminary results. The 

full report should be ready by mid-winter. I suspect our atrazine prohibition 

areas are a "microcosm" for research that doesn't exist anywhere else in the 

U.S.

Melanie,

Thanks for your detailed response. I really appreciate the additional 

references and details.

I have had a chance to work through some of the details and the "missing link" 

from my perspective is where the regulations are headed with respect to 

environmental and municipal water residues and where the onus (or 

responsibility) will fall to bring water into regulatory compliance? I would 

be delighted set a time to discuss this further. I have also taken the liberty 

of copying my lead scientist around the triazine degrading system we have 

developed and our North American Business Manager.

Thanks in anticipation of your additional assistance and support.

Subject: Re: FW: Update from CSIRO on pesticide remediation technology

Hi Cameron,

 Thanks for your email and I apologize for the delayed response.

Nancy talked to me about her conversation with you, and some time back I

tried to call and leave a voicemail for you but I don't think it got

through.

 Below I've included some information on EPA's current human health

evaluation of atrazine, as well as some links to additional information

about our regulation of atrazine. If you have any questions, please

feel free to call or email me (it might be helpful to email regarding a

time to call, however, because of the time difference).

 In 2003, EPA re-registered atrazine, which was EPA's last major

regulatory decision specifically for this herbicide. Given the new

scientific information generated since the 2003 reregistration decision

and the documented presence of atrazine in both drinking water sources

and other bodies of water in the US, EPA is reviewing the new research

to ensure that its regulatory decisions regarding atrazine are based on

the best available science and protect public health and the

environment.

 This year, EPA held three FIFRA Scientific Advisory Panel (SAP)

meetings on human health issues related to atrazine. These SAPs

included atrazine research regarding toxicology and epidemiology. The

SAP meetings ensure scientific soundness and integrity in the assessment

of science issues associated with atrazine and provide EPA independent,

outside scientific advice on these issues. The SAP itself is a peer

review panel comprised of independent scientists who are experts in

fields relevant to atrazine science. The SAP meetings are also open to

the public, and EPA encourages interested parties to participate in

these meetings.

 In February, EPA presented and sought scientific peer review of

its proposed plan for incorporating epidemiology studies into the

atrazine risk assessment. In April, EPA presented and sought scientific

peer review of its evaluation of atrazine effects based on experimental

laboratory studies that will inform the selection of endpoints and
safety factors in the risk assessment, and the sampling design currently

used to monitor drinking water in community water systems. In September,

EPA presented and sought scientific peer review of its evaluation of

atrazine non-cancer effects based on experimental laboratory studies and

epidemiology studies. The September review was intended to include any

new experimental laboratory data since the April SAP meeting.

 Through these SAPs, EPA presented and sought peer review of its

evaluation of approximately 120 toxicology studies and 25 epidemiology

studies. If you are interested in reading EPA's reviews of these

studies, as well as meeting transcripts and the SAP's recommendations to

EPA on this research, see the Agency's 2010 SAP Meetings Web page,

http://www.epa.gov/scipoly/sap/meetings/2010/index.html, which provides

meeting minutes and transcripts when they become available.

 In 2011, EPA plans to hold another peer review concerning findings

of the Agricultural Health Study (http://aghealth.nci.nih.gov/) as well

as epidemiology and laboratory animal studies on atrazine. At the

conclusion of this evaluation of atrazine's human health effects, EPA

plans to ask the SAP to review atrazine's potential effects on

amphibians and aquatic ecosystems. As a result of the current atrazine

science evaluation, EPA plans to make any needed risk management

decisions on atrazine consistent with the science and US statutes.

 For more information about the EPA Office of Pesticide Program's

current regulatory requirements for atrazine, see the Office of

Pesticides' Atrazine webpage at:

http://www.epa.gov/pesticides/reregistration/atrazine/index.htm. For

updates on EPA's activities that follow up on atrazine's 2003

reregistration, as well as updates on the current science evaluation of

atrazine, see the Atrazine Updates website at:

http://www.epa.gov/pesticides/reregistration/atrazine/atrazine_update.htm

 I hope this information is helpful and again, if you have any

questions just let me know. Also, I should note to you that any

communications EPA receives on atrazine and drinking water are required

to be placed in the public docket. I noticed Nancy also asked about

that, but I just wanted to make sure that there would be no

confidentiality issues in placing the presentation in the public docket.

 Thanks very much and I look forward to hearing from you.

Melanie,

By way of introduction, Nancy Fitz suggested that I get in contact with

you following correspondence we have had around atrazine and the current

and emerging regulatory outlook.

Please find attached a recent peer reviewed publication we have around

our triazine technology. Furthermore, I attach an updated overview that

I gave at a recent (biotech) conference in DC.

I understand that there are some deliberations underway (from a water

quality perspective) around triazines and would be curious to get any

insights from you around the process and current tenor of thinking about

what is to be proscribed from a regulatory perspective - I am finding

hard to cut through the "noise" on the internet on this issue!

I would be pleased to catch up by phone if that is more convenient to

discuss this matter.

Hi Cameron,

Thanks for the quick response and the clarification that the contents of

the PDF are not confidential. I'll work on adding this information to

the TPSA web site.

Melanie Biscoe, who I referred you to earlier, is the right person to

talk with about insights into the status of the triazines. Her email is

biscoe.melanie@epa.gov and her phone number is 703-305-7106. Sorry that

I can't help on that front, but I'm not involved with it at all.

Nancy,

Thanks for your note. The contents of that PDF are non confidential so

no problem.

The disclaimer is for investor / finance folks.

Any insights into the triazine latest would be great.

Best regards,

Regards,

Cameron

Hi Cameron,

Sorry for taking so long to get back to you! Last Friday I was writing

up some News updates for the TPSA web site and was getting ready to add

one with the information you sent me. But as I looked through the
information, I realized that the second page of the overview document

includes all sorts of restrictions like "provided on a strinctly private

and confidential basis to be used solely by the recipient." I wanted to

check with you to see if you wanted this posted on the TPSA web site

and, if so, if you could delete that page because it would certainly

raise a lot of questions.

Thanks!

 |Update from CSIRO on pesticide remediation technology

|

Nancy,

I hope that this finds you well. Sorry for being an intermittent

correspondent these past months. We, CSIRO, have been very busy with the

bioremediation technology that I presented in Savannah earlier this

year.

Please find attached an recent peer reviewed publication we have around

our triazine technology. Furthermore, I attach an updated overview that

I gave at a recent (biotech) conference in DC. We have had no recent

public announcements per se, but are hoping that things we are working

on now will be in the media later this year. I have very early plans to

be in San Antonio, but there is a lot of water yet to pass under that

bridge before those plans are finalized.

I understand that there are some deliberations underway (from a water

quality perspective) around triazines and would be curious to get any

insights from you around the process and current tenor of thinking about

what is to be proscribed from a regulatory perspective - I am finding

hard to cut through the "noise" on the internet on this issue!

Thanks in anticipation of your ongoing interest in our work.
Best regards,

Cameron Begley
