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.

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,

### (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. Best Regards,

**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.**  **Best Regards, Melanie Biscoe**  **Chemical Review Manager Special Review and Registration Division**  **Office of Pesticide Programs biscoe.melanie@epa.gov**  **703-305-7106 n.d.jablonowski**  **05/03/2009 03:52:35 PM Dear Melanie, dear Tracy, dear Mark, please giv...**

### 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.

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?

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.

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.

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.

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.

# 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, 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. (Embedded image moved to file: pic06541.gif) (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. (See attached file: drinkingwater.pdf) (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.

### 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.

### 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.

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.

### 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. Sincerely, Helen On Mon, Sep 27, 2010 at 1:35 PM, < Biscoe

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

Thanks Melanie. Could you also include these questions when you consult with your colleagues? 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?

Hi Melanie, I am looking at the atrazine reregistration website ( http :// www . epa . gov / oppsrrd 1 / reregistration / atrazine / atrazine

_ 

### update

. htm ) and I have some questions regarding the terms used. How does the EPA calculate a 90-day rolling average for atrazine? I've been looking online, but it seems like every website has a different definition. So I thought I would send you an email about it since you or your department would know it best. My current understanding is that EPA averages day 1 through 90, then averages day 2 to 91, then day 3 to 92 to get a 90-day rolling average. Could you please give me the correct definition? I would greatly greatly appreciate it. Thank you! Helen**----- Forwarded by Melanie Biscoe/DC/USEPA/US on 12/20/2010 11:34 AM -----**

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.

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. Jeff Postle DATCP-ARM (608) 224-4503

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, Melanie Biscoe Chemical Review Manager Risk Management and Implementation Branch IV (RMIB IV) Pesticide Re-evaluation Division (PRD) Office of Pesticide Programs (OPP) biscoe.melanie@epa.gov 703-305-7106**----- Forwarded by Melanie Biscoe/DC/USEPA/US on 12/20/2010 11:34 AM -----**

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.

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.Thanks in anticipation of your assistance

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 workingon now will be in the media later this year

be in San Antonio, but there is a lot of water yet to pass under that bridge before those plans are finalized.

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.

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. Jeff Postle

Okay. Let's move the meeting to November 29th. Jeff and I are both available anytime after 10:30 (our time). If that doesn't work for you, we can also meet anytime before 12:00 on the 30th. Any questions you could provide will give Jeff and I a chance to review the files, as we went through this 15+ years ago.

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,Melanie Biscoe

Melanie, Would it be possible for us to delay the start of our scheduled phone meeting tomorrow one hour? (Or from 12-1 our time, 1-2 DC time). 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 to discuss before the meeting? Thanks Rick

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. Jeff Postle DATCP-ARM (608) 224-4503

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, Melanie Biscoe Chemical Review Manager Risk Management and Implementation Branch IV (RMIB IV) Pesticide Re-evaluation Division (PRD) Office of Pesticide Programs (OPP) biscoe.melanie@epa.gov 703-305-7106

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. Best regards,

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 andsafety 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.

Subject: FW: Update from CSIRO on pesticide remediation technology

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. Thanks in anticipation of your assistance. Best regards,

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!
