Hi Dan, Just following up on the data for the AMP and SMP. Please send the spreadsheet when you get a chance. Also, if you have an electronic copy of the study s ubmissions, please email those as well.

Can you provide the dropbox info for the AMP and SMP submissions? 4. Could we put the ecomonitoring data from 2009-2010 in the docket without a 10g restriction?**  **5. Regardless of your answer to question4, could we provide the 2009-2010 ecomonitoring data to the states?

Dear Melanie and Kristen, Thank you very much for your help. It was extremely useful. I have transmitted all this knowledge to the requesting pe rson. Best regards,

Lorenzo Office of Agricultural Affairs 1600 New Hampshire Ave. NW Washington D.C. 20009 Tel: 202-238-6443 Fax: 202-332-1324 -----Original Message----- From: Biscoe.Melanie@epamail.epa.gov [mailto:Biscoe .Melanie@epamail.epa.gov] Sent: Monday, March 21, 2011 3:45 PM To: Laura Lorenzo Cc: Hendricks.Kristen@epamail.epa.gov Subject: Pesticide Questions Follow-up: Atrazine & Uses on Parsley, Oregano, and LettuceHi Laura ,

With regard to atrazine label precautions in the US , I've attached two labels from products sold and used in the US. One label is for an emulsifiable concentrate (liquid) and one is a wate r dispersible granule. (I've included both because they are diff erent formulations that have different allowable application methods, both of which result in different worker protection requirements). .As i ndicated by its conclusions in its regulatory documents and stateme nts on its websites, EPA is primarily concerned with reducing human and environmental exposures to atrazine in water because atrazine doe s not readily adsorp onto soil and, as a consequence, is prone to runnin g off fields into water bodies when it rains. Such contamination can impact aquatic ecosystems, drinking water sources, or both. To tha t end, many of the use restrictions you'll find on the atrazine labels involve setbacks from waterbodies, wellheads, drainage outlets, etc. Additionally, the labels specify a lower rate for pre-plant applicati on when soils are "highly erodable." Atrazine is also a Restricted U se Product (RUP), which requires that atrazine applicators be certifi ed. If you have any questions or concerns regarding any particular labe l language for atrazine, please let me know. (See attached file: Jan-25-2010 AATREX NINE-0 Herbi cide - Water Dispersible Granules.tif)(See attached file: May-1- 2009 AATREX 4L Herbicide - Emulsifiable Concentrate.tif)
With regard to pesticides that can be used on parsl ey, oregano, and lettuce in the US, generally growers often work wit h their local cooperative extension agent to determine what produ cts are appropriate for particular pests in that area. Additionally, s tates often have their own use restrictions, so some products that a re used on one state may not be allowed for use in another. The USDA's Cooperative Extension System does have a website so growers can readily c ontact their extension agent (http://www.csrees.usda.gov/Extensi on/) but does not seem to have a list of products, generally, that ca n be used on an individual crop or commodity. Given that there's not a readily-available online " go-to" source for this information, the second-best source of informa tion is to look at the US tolerances for parsley, oregano, and lettuce . I've compiled them in the spreadsheet below. The tolerance listings a re indicative of what is or what used to be used on these products in the US. For example, there is a tolerance for lindane on lettuce even th ough lindane has been cancelled in the US for several years. Additionall y, uses of azinphos-methyl and endosulfan are being phased out but still have tolerances. If there are any specific pesticide pr oducts on this list for which you'd like to know the actual registratio n status in the US, you can go to the US Code of Federal Regulations we bsite's "simple search" webpage: http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?sid=c ff737be0635de1c6ea34a334c 513e33&c=ecfr&page=simple
and where it says "Enter a Title Number" type in: 40 where it says "Search for" type in: the chemical n ame (for example, endosulfan) That should bring up listings of US decisions on th at particularchemical ( or specific products associated with that chemical ) , so you

can see whether the chemical is registered in the U S. That said, if you still feel as though you need the listing of chemicals used on parsley, oregano and lettuce (as opposed to the tolerances) please let Kristen of I know and we can see if it's possible to get more targeted information through another division of ou r office. (See attached file: 3-21-11 US Tolerances for Parsl ey Oregano & Lettuce.xlsx)

I hope this helps. If you have any additional ques tions, concerns, or requests, just let me know.

Attached are EPA's re vised risk assessments for atrazine from 2002 that supported the 2003 reregist ration decision. The "Special Docket" has additional documents related t o these risk assessments. I suggest that before you read these go ahead and r equest the whole DVD using the instructions in the docket so if you come acros s a reference in the revised assessments below you can have the informat ion readily available through that DVD. (See attached file: hed_redchap_16apr02.pdf)(See at tached file: efed_redchap_22apr02.pdf) With regard to rural wells, acute exposures to atra zine and the chlorinated metabolites in drinking water from rural wells do n ot exceed the Agency’s LOC. However, the Agency has some concerns for potential chronic exposures of infants and children drawing drinking water from ru ral wells located directly in atrazine use areas, i.e., adjacent to fields whe re atrazine was used.Current atrazine products contain requirements that are intended to prevent

contamination of residential wells. Based on the li mited available well monitoring data only 8 of 1505 wells sample had levels of atrazine that excee ded the level of concern. The 1505 wells monitored were selected based on the ir location in areas with high atrazine use. These 8 wells were subsequently resampled and all concentrations of atrazine and the chlorinated meta bolites were less than the Agency’s LOC. Although the data indicate that leve ls are decreasing in these wells over time, to be protective of infants using private rural wells in close proximity to atrazine use areas, the Agency r equired the registrant to conduct a study to identify characteristics that ar e predictive of the potential vulnerability of a rural well to atrazine contamination. EPA expects to receive this study by summer 2011 and wi ll review it to see if additional monitoring data are needed or if conclus ions can be drawn. If you have any additional questions or requests pl ease let me know.

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

Dear Ms. Biscoe, I was wondering if you were able to pull together s ome answers for my other questions about atrazine in drinking water an d pregnant women? I am still currently working on my project, although I am now focused on the risk management aspects of atrazine. If possibl e, do you think you could find the answer to the following two question s? I really appreciate your help with everything! Question One: Is the EPA is involved in any health education practices to inform the public about atrazine in drinking wat er? Have there been efforts to educate the public in the communities fo und with elevated levels of atrazine in their drinking water? Question Two: What types of control does the EPA en dorse (at the source, along the path, and at a personal level) in order to limit the levels of atrazine exposure through drinking water? Again, thank you so much for your time and help! Jessica Poppe jessica.poppe@tufts.edu 978-844-1511Quoting Biscoe.Melanie@epamail.epa.gov:
