### Abstract This document presents EPA’s decision regarding the reregistration eligibility of the currently registered uses of the active ingredient simazine . The Agency has conducted human health and environmental fate and effects risk assessments for simazine and has made tolerance reassessment decisions for existing tolerances. S imazine has also been determined to share a neuroendocrinemechanism of toxicity with two other structurally - related chlorinated triazines, atra zine and propazine, and their three chlorinated degradates . T he Agency has completed its cumulative risk assessment for the chlorinated triazine class of pesticides , concluding that with the mitigation measures in this document and in the 2003 IRED for at razine the cumulative risks associated with these pesticides are below the Agency’s level of concern. The Agency has determined t hat , with label amendments and changes as specified in this document and the 2003 IRED for atrazine , there is a reasonable cer tainty that no harm will result to the general U.S. population, infants, children, or other major identifiable subgroup s of consumers , from the use of simazine, atrazine, and propazine. T he Agency has determined that simazine will be eligible for reregist ration provided that the risk mitigation measures outlin ed in this document are adopted and label amendments are made to reflect these measures . EPA has identified potential human health risks of concern associated with the current registered uses of sima zine from dietary exposure from drinking water, residential exposure, and occupational exposure. EPA has also identified potential ecological risks of concern to nontarget organisms. To reduce these exposures and to address subsequent risks of concern, EPA is requiring a number of mitigation measures such as prohibiting s pecific uses, formulations, and application methods; reducing maximum application rates to typical rates; establishing a performance standard for raw water concentrations; requiring appr opriate PPE for occupational handlers; and adding setbacks from wells and waterways. The Agency is also requiring appropriate data to confirm the decisions presented in this RED. The Agency has determined that simazine is eligible for reregistration prov ided that the risk mitigation measures outlined in this document are adopted and label amendments are made to reflect these measures.

### I. Introduction The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was amended in 1988 to accelerate the reregistration of products with active ingredients registered prior to November 1, 1984, and amended again by the Pesticide Registration Improvement Act of 2003 to set time frames for the issuance of Reregistration Eligib ility Decisions ( RED s ) . The Act calls for the development and submission of data to support the reregistration of an active ingredient, as well as a review of all data submitted to the Environmental Protection Agency (hereafter referred to as EPA or the A gency) . Reregistration involves a thorough review of the scientific database underlying a pesticide's registration. The purpose of the Agency's review is to reassess the potential hazards arising from the currently registered uses of a pesticide; to dete rmine the need for additional data on health and environmental effects; and to determine whether or not the pesticide meets the “ no unreasonable adverse effects ” criteria of FIFRA. On August 3, 1996 , the Food Quality Protection Act (FQPA) was signed int o law. This Act ame nded FIFRA and the Federal Food, Drug, and Cosmetic Act (FFDCA) to require reassessment of all existing tolerances for pesticides in food ; by August 3, 2006, EPA must review all tolerances in effect as of August 2 , 1996. In reassessing these tolerances, the Agency must consider, among other things, aggregate risks from non - occupational sources of pesticide exposure, whether there is increased susceptibility among infants and children, and the cumulative effects of pesticides that have a common mechanism of toxicity. When the Agency determines that aggregate risks are not of concern and concludes that there is a reasonable certainty of no harm from aggregate exposure, the tolerances are considered reassessed. EPA decided that, for thosechemicals that have tolerances and are undergoing reregistration, tolerance reassessment would be accomplished through the reregistration process. FQPA requires EPA to consider “ available information ” concerning the cumulative effects of a particular p esticide's residues and “ other substances that have a common mechanism of toxicity ” when considering whether to establish, modify, or revoke a tolerance. Potential cumulative effects of chemicals with a common mechanism of toxicity are considered because low - level exposure to multiple chemicals causing a common toxic effect by a common mechanism could lead to the same adverse health effect as would a higher level of exposure to any one of these individual chemicals. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the policy statements released by EPA's Office of Pesticide Programs concerning common mechanism determinations and procedures f or cumulating effects from substances found to have a common mechanism on EPA's website at http://epa.gov/pesticides/cumulative/ . The Agency has classified the structurally- related chlorinated triazines a trazine, simazine, and propazine , and their three c hlorinated degradates , as sharing a common neuroendocrine mechanism of toxicity. The Agency has completed its cumulative risk assessment for t he chlorinated triazine class of pesticides and hasconcluded that with the mitigation measures in this document and in the 2003 I nterim Reregistration Eligibility Decision (I RED ) for atrazine the cumulative risks associated with these pesticides are below the Agency’s level of concern. The cumulative risk assessment and supporting documents are available in the pub lic docket EPAPage 9 of 266

### Simazine is a chlorinated triazine herbicide, a class of herbicides that also includes the pesticides atrazine and propazine. The Registr ation Standard was completed for simazine on August 1, 1984. The Registration Standard also required the submission of generic and productspecific data to support the continued registration of simazine. A Data Call - In (DCI) was issued f or simazine in Se ptember 1991 . Subsequent DCIs were issued in August 1992, March 1995 and October 1995. This RED reflects a n a ssessment of all data submitted to date. In 1994 EPA’s Office of Water (OW) established a Maximum Contaminant Level (MCL) for simazine in finis hed drinking water of 4.0 parts per billion (ppb). OW established this MCL under the Safe Drinking Water Act (SDWA) and simazine has been subject to compliance monitoring at Community Water Systems (CWS) since 1993 . This compliance monitoring typically c ons ists of samples taken quarterly at CWS in simazine use areas. In November 1994, EPA initiated a Special Review for the triazine pesticides, which at that time included atrazine, simazine, and cyanazine, as announced in a Federal Register Notice, 59 FR 60412. The basis for the Special Review included the potential for cancer risks of concern resulting from dietary or occupational exposure as well as the potential fo r human health risks of concern resulting from drinking water exposure caused from groun d and surface water contamination. At the time that the Special Review was initiated, atrazine and the other triazines were classified as Group C carcinogen s , or possible human carcinogen s . Cyanazine registrations were cancelled effective December 1999 a nd atrazine and simazine were later reclassified as “not likely to be carcinogenic to humans.” Th e Agency expects to be able to close out the Special Review after considering comments from a Scientific Advisory Panel that will meet in 2007 to review curre ntly available data and pending data from the National Cancer Institute concerning the carcinogenic potential of atrazine. B **.** Use and Usage Profile The following is information on the currently registered use s of simazine . Sections IV and V includeinformation on thosecurrently registered uses which are not eligible for reregistration and Appendix A provides a detailed table of those uses which are eligible for reregistration . Type of Pesticide: Simazine is a systemic herbicide that is usually applied to soil, absorbed through leaves and roots, and acts by inhibiting photosynthesis within the targeted plant. It is widely used as a selective herbicide to control most annual grasses and broadleaf weeds befo re they emerge or after removal of weed growth. Formulations: Simazine is formulated as granules , pellets / tablets, dry flowables, wettable powders, emulsifiable concentrates, flowable concentrates , and ready - to - use liquids.

### Methods of Application : E nd - use product s containing simazine may be applied on the ground by broadcast across an area, as a spot treatment, or in rows, which is also referred to as band treatment. Some pro duct s can also be applied by aerial broadcast. Use Sites: Simazineis reg istered for pre - plant use or use in established fields of a variety of food and feed crops including, but not limited to, fruit and nut crop s , such as apples, oranges, and almonds, in addition to corn. Simazine can also be applied at forestry sites and on turfgrass grown commercially for sod. Nonagricultural uses for simazine include application as nonselective weed control on noncrop land, which consists of industrial sites, highway medians and shoulders, railroad rights - of - way, lumberyards, petroleum ta nk farms, and noncrop areas on farms such as around buildings, equipment and fuel storage areas, along fences, road - sides, and lanes. Simazine is also registered for residential use on turfgrass including both commercial use on recreational lawns such as golf courses and commercial or homeowner use on home lawns . There is an additional registration for simazine as an alg ae cide in ornamental ponds and aquariums of 1,000 gallons or less. Application Rates: For agricultural uses, t he maximum use or application rates range from 1 to 9.6 pounds active ingredient per acre (lbs ai/A). For noncrop land, maximum application rates are 40 lbs ai/A , and for use specifically on turfgrass, 4 lb s ai/ A. EstimatedUsage: An estimated 5 to 7 million pounds of simazine are applied domestically to agricultural crops each year, and an additional 1.2 million pounds are applied for nonagricultural uses. Of these totals, n

early 2 million pounds of simazine are appliedeach year in the Midwest ( more than 90% on corn ) ; more th an 1 million pounds are applied in California on fruits and nuts (90% on almonds, grapes, oranges, and walnuts); and more than 1 million pounds are applied in Florida on c itrus (more than 85% on oranges and nearly 15% on grapefruit). Simazine is also used on a variety of other crops including , but not limited to , apples, peaches, filberts ( i.e., hazelnuts ), pecans, blackberries, and raspberries. C . Tolerances Currently there are 62 tolerances listed in 40 CFR 108.213 f or simazine on agricultur al crops and animal commodities . With the exception of tolerances set for bananas and fish, tolerances for simazine residues are currently expressed in terms of the parent compound ( simazine ) only. In addition to bananas and fish , tolerances for simazine current ly exist for alfalfa, alfalfa (forage and hay), almond, almond (hulls), apple , avocado , Bermuda grass, Bermuda grass (forage and hay), blackberry, blueberry, boysenberry, cattle (fat , meat Page 12 of 266

Section IV includes a summary of the tolerance reassessment decision for simazine and lists those tolerances the Agency will propose to revoke, decrease, increase, maintain, reassign, and establish . III. Summary of Risk Assessment s A. Human Health Risk Assessment 1. Hazard Profile Historically, EPA’s Office of Pesticide Programs ( OPP ) has classified pesticides into four acute toxicity categories ranging from Toxicity Category I(most toxic) to Toxicity Category IV (least toxic) . These toxicity categories reflect the doses or concentrations that, in an acute toxicity study, are lethal to at least 50% of the test animals in the group or are severely irritating. Non- lethal endpoints, such as those observed in histophathological evaluations or through clinical chemistry measurements, are not reflected in the toxicity categories. OPP uses six separate studies todetermine the t oxicity c ate gory classification for a pesticide

–an acute oral study, an acute dermal study, an acute inhalation study, an eye irritation study, a skin irritation study, and a dermal sensitization study. Simazine is not acutely toxic and is classified as Toxicity Category I V via the oral route of exposure and Toxicity Category III via the dermal and inhalation routes of exposure. Simazine is not an eye or skin irritant, nor is the compound a dermal sensitizer. This information is summarized in Table 1. Table 1. Su mmary of Acute Toxicity Categorization for Simazine Guideline Number Study Type MRID(s) Results Toxicity Category 870.11 00 Acute Oral 00 148897 LD 50 > 5 g/kg (males and females combined) IV 870.12 00 Acute Dermal 00 148898 LD 50 > 2 g/kg III 870.13 00 Acut e Inhalation 00 148899 LC 50 > 1.71 mg/L III 870.24 00 Primary Eye Irritation 00 148900 Slight irritant IV 870.25 00 Primary Dermal Irritation 00 148901 PIS = 0.2 IV 870.26 00 Dermal Sensitization 41184501 Negative N/A 

### In a sub - chronic development al toxicity study, incomplete or absent bone formation or ossification was observed in fetal rats following exposure of pregnant rats tosimazine. These developmental effects are presumed to occur after a single exposure and are therefore appropriate for considerati on in the acute exposure scenario for dietary risk from food and drinking water. Page 13 of 266

### A fter subchronic and chronic exposure to simazine, a variety of species were shown to exhibit neuroendocrine effects resulting in both reproductive and developmental consequen ces that are cons idered relevant to humans. These effects are biomarkers of a neuro endocrine mechanism of toxicity that is shared by several other structurally- related chlorinated triazines including atrazine, propazine, and three chlorinated degradates

–G- 28279 (des - is opropyl atrazine or DIA), and G - 30033 (des - ethyl atrazine or DEA) , and G- 28273 (diaminochlorotriazine or DACT)

–the first and last of which can result from the degradation of simazine . These six compounds disrupt the hypothalamic - pituitary- gonadal (HPG) axis, part of the central nervous system, causing cascading changes to hormone levels and developmental delays. The se neuroendocrine effects are considered the primary toxicological effects of regulatory concern for all subchronic and chro nic exposure scenarios including dietary risk from food and drinking water, residential risk, and occupational risk. Simazine’s two chlorinated degradates, DIA and DACT , are considered to have toxicity equal to the parent compound in respect to their commo n neuroendocrine mechanism of toxicity. Another degradate, G - 30414 ( hydroxy - simazine), was identified, which is expected to have a different toxicological profile from simazine based on the toxicological data available for an analogous metabolite for atra zine, hydroxy - atrazine. On the basis of the results of a risk assessment for hydroxy - atrazinethat showed minimal exposure and risk , anticipated exposure, and consequently risk, to hydroxy - simazine in the diet would be expected to be very small. Therefore the degradate hydroxy - simazine was not included in the human health risk assessment. Simazine was originally classified in 1989 as a Group C carcinogen, or possible human carcinogen, and was considered to have a non - threshold mechanism for tumor formatio n. In other words, a threshold, or dose below which the risk of developing cancer is negligible , had not been identified for simazine. Mode of action data were later received and examined by the Agency in regards to the ability of atrazine to induce mamm ary tumors in female rats through the neuroendocrine mechanism of toxicity the compound shares with simazine. As a result of evidence that the events leading to the tumor formation are species/strain specific and not operative in humans, atrazine was recl assified in 2000 as “ not likely to be carcinogenic to humans . ” S imazine was similarly reclassified in 2005 based on weight - of - evidence that it is not genotoxic and operates via a mode of action for the development of mammary and pituitary tumors in female rats similar to atrazine . Consequently, cancer risks have not been assessed in the human health risk assessment . Following the 2000 reclassification of atrazine and during the reregistration process for atrazine, the Agency reviewed subsequent cancer epi demiology studies regarding atrazine’s potential link to cancer and convened a Scientific Advisory Panel (SAP) to further review the studies . Results of these studies did not alter EPA’s conclusion that atrazine is “not likely to be carcinogenic to humans .” EPA has recently received three new pieces of information concerning atrazine and its possible association with carcinogenic effects : a report from the National Cancer Institute (NCI) re - analyzing previous epidemiologic studies of atrazine and non - Hodg kin’s lymphoma, an epidemiological study of all cancers related to atrazine exposure from NCI’s Agricultural Health Study, and a nested case - control study conducted for Syngenta Crop Protection, Inc. of workers at an atrazine manufacturing plant in St. Gab riel, Louisiana. These studies are currently undergoing rev i ew. At this time there are two other studies pending in the near futurefrom NCI's Agricultural Health Study that will include atrazine. EPA expects to Page 14 of 266

### receive and review in 2006 or early 2007 an updated epidemiological study and analysis concerning the potential connection between multiple pesticides and prostate cancer as well as a similar study on non - Hodgkin's lymphoma, although completion of the latter study depends upon identification by N CI of enough cases of this relatively rare canc er . After the two pending studies have been received and reviewed , the Agency plans to convene another SAP meeting in 2007 concerning atrazine and its possible association with carcinogenic effects. At that m eeting, EPA intends to present the SA P with all of the data bearing on atrazine and cancer, including old and new epidemiology studies and laboratory animals studies . In the meantime, EPA will continue to review all new data submissions in addition to the NCI studies . If at any time results from a n y of t hese submissions raise significant questions that would benefi t substantially from S A P review prio r to submission of all of the data, the Agency will hold a SAP meeting before all aspects of NCI’s Agricult ural Health Study are completed. EPA intends to thoroughly review any SA P report from any future meeting, once issue d , and to review its determinations regarding the car c inogenic potential of atrazine, and simazine, as necessary. E PA will also continue t o review any future additional studies performed by NCI that include atrazine or simazine. Based on the toxicity profile and major exposure routes of simazine and its two chlorina ted degradates, toxicological endpoints (based on c ritical health effects ob served in toxicity studies on animals ) and corresponding doses or concentrations, were derivedfor the following exposure durations : acute (1 day) for females ages 13 to 49 only, short - term (1 - 30 days), intermediate - term (1 month - 6 months), and long - term o r chronic (more than 6 months). All endpoints, aside from the acute endpoint used for females ages 13 to 49 derivedfrom a toxicity study on animals exposed to simazine , were derived from toxicity studies on animals exposed toatrazine in lieu of simazine - specific studies. Because the database for simazine’s potential neuroendocrine effects is less robust than the atrazine database, particularly for the young, t he Agency concluded that atrazine data c ould be used as bridging data for simazine due to the f act thatsimazine and atrazine share the neuroendocrine mechanism of toxicity described above and that these neuroendocrine effects are considered the primary toxicological effects of regulatory concern for the relevant exposure durations . These effects a re considered to be applicable to the general U.S. population , including infants and children. Table 2 p resents a summary of the toxicological endpoints and corresponding doses or concentrations for each exposure scenario considered. The vocabulary and c alculations in this table are further explainedbelow.

### 2. D ietary Exposure and Risk f rom Food EPA considers acute, chronic , and, if relevant, cancer dietary risks from food . Acute dietary risk from food is calculated considering what is eaten in one day and maximum, or highend, residue values in food. An acute risk estimate that is less than 100% of the acute Population Adjusted Dose (aPAD), the dose at which an individual could be exposed on any given day and no adverse health effects would be expecte d, is not of concern to the Agency. Chronic dietary risk from food is calculated using the average food consumption values for each population sub group and average residue values in/on those foods over a 70 year lifetime to determine average exposure. A chronic risk estimate that is less than 100% of the chronic Population Adjusted Dose (cPAD), the dose at which an individual could be exposed over the course of a lifetime and no adverse health effect would be expected, is not of concern to the Agency. The aPAD and cPAD are the acute reference dose (aRfD) and the chronic reference dose (cRfD), respectively, adjusted for the Food Quality Protection Act (FQPA) safety factor, a method of accounting for the potential for increased susceptibility of infants a nd children to toxic effects. The Agency determined it was unnecessary to retain a safety factor in the acute dietary assessment to account for hazard - based uncertainty because open literature data demonstrate that any neuroendocrine effect , the primary t o xicological effects of regulatory concern, that could result from a single dose would o nly occur at a very high dose. However, when available water monitoring data were used to estimate drinking water exposure, a 3X FQPA safety factor was retained to acc ount for exposure - based uncertainty due to limitations in the monitoring database . The full10X FQPA safety factor was retained and applied to the chronic dietary assessment to account for both exposure - based uncertainty in the water monitoring dat a and b ecause of residual uncertainty regarding the effects of the neuroendocrine mechanism of action on the developing child. When drinking water exposure estimates were calculated using modeling, a conservative approach likely to overestimate actual exposure, the FQPA Safety Factor was reduced to 1X for acute assessments and 3X for chronic assessments. T he aRfD and cRfD are derived from toxicity studies on animals and are based on the highest dose or level of exposure at which no adverse effects were observab le ( “ no observed adverse effect level ” or NOAEL). For simazine, a developmental endpoint was identified for acute exposure based on adverse effects of incomplete or absent bone formation observed in a developmental study on female rats exposed to simazine . A neuroendocrine endpoint was identified for chronic exposure based on adverse effects of estrous cycle alterations and luteinizing hormone (LH) surge suppression observed in a n LH surge study on female rats exposed to atrazine . Neuroendocrine effects such as these are the primary toxicological effects of regulatory concern for simazine . Corresponding NOAELs are listed below. A total uncertainty factor of 100X is applied to the NOAELs in calculating the aRfD and cRfD to account for both intraspecies v ariability ( i.e., differences among humans) at 10X and interspecies extrapolation ( i.e., uncertainty in extrapolating from animal data to humans ) at 10X. Potential residues of concern in food are simazine plus its two chlorinated degradates DIA and DACT. Existing field trial data, the United States Department of Agriculture’s (USDA) Pesticide Data Program (PDP), and the Food and Drug Administration ’s (FDA) monitoring data indicate non - detectable residues (less than 0.05 ppm) of simazine. Given that sima zine is an Page 18 of 266

### herbicide applied mostly pre - plant by broadcast or by band treatment ( where pesticide is applied to the field in bands or rows) to soil, the lack of detections in edible portions of crops is not surprising. Dietary exposure to simazine fr om foo d is estimated to be essentially zero, resulting in a risk esti mate of 0% of the aPAD and cPAD which is not of concern to the Agency. • Estimated acute dietary risk from food for females ages 13 to 49 only is 0% of the aPAD. o aPAD of 0.1 mg/kg/day = 0.3 mg/k g/day (aRfD) ÷ 3 (FQPA safety factor) o aRfD of 0.3 mg/kg/day = 30 mg/kg/day (NOAEL) ÷ 100 (uncertainty factor for intraspecies variability and interspecies extrapolation ) • Estimated chronic dietary risk from food for the general U.S. population and all subg roups is 0% of the cPAD. o cPAD of 0.0018 mg/kg/day = 0.018 mg/kg/day (cRfD) ÷ 10 (FQPA safety factor) o cRfD of 0.018 mg/kg/day = 1.8 mg/kg/day (NOAEL) ÷ 100 (uncertainty factor for intraspecies variability and interspecies extrapolation ) 3. Dietary Exposu re and Risk from Drinking Water Drinking water exposure to pesticides can occur through surface and ground water contamination. EPA considers acute , chronic , and, if relevant, cancer d ietary risks from drinking water and uses either modeling or monitoring data, if available, to estimate those risks. To determine the maximum allowable contribution from water in the diet, EPA first looks at how much of the overall allowable risk is contributed by food and then calculates a “ drinking water level of comparison ” (DWLOC) using the acute or chronic PAD as described above . The DWLOC represents the maximum contribution to the human diet (in ppb ) that may be attributed to residues of a pesticidein drinking water after dietary exposure from food is considered. Acute and chronic r isks from drinking water are assessed by determining if the DWLOC is exceeded by monitored or modeled concentrations in both surface and ground water. Concentrations th at

are less than the DWLOC are below the Agency’s level of concern . For simazine, the DWLOCs are based on 100% of the aPAD and cPAD because dietary exposure from food has been estimated at zero. Simazine is persistent and mobile and detected in both surf ace and ground water . P otential residues of concern in drinking water aresimazine plus its two chlorinated degradates, DIA and DACT . DWLOCs were calculated for various subpopulations for comparison against concentrations of simazine and its two chlorinated degradates as monitored in drinking water and as predicted through modeling which the Agency believes to be conservative and protective . For those DWLOCs calculated for comparison to concentration values generated through conservative modeling, the 3X FQPA safety factor included in the calculation to account for exposure - based concerns for inadequ ate monitoring data was removed because the models are protective and provide upper - bound concentrations.

### DWLOCs for comparison against concentrations as mo nitored in drinking water : • Acute DWLOC for females ages 13 to 49 only for comparison against maximum peak water concentration based on monitoring data = 3000 ppb • Chronic DWLOC for comparison against 90 - day average and annual average concentrations based o n monitoring data: o Infants and children less than 1 year old= 12 .5 ppb o Children ages 1 to 6 = 23 ppb o Children age s 7 to 12 = 53 ppb o Females ages 13 to 49 = 60 ppb o General U.S. population = 68 ppb DWLOCs for comparison against concentrations as predicted though modeling : • Acute DWLOC for females ages 13 to 49 only for comparison against maximum peak water concentrations based on models = 9000 ppb • Chronic DWLOC for comparison against 90 - day average and annual average concentrations based on models: o Infants and children less than 1 year old= 3 7.5 ppb o Children ages 1 to 6 = 69 ppb o Children ages 7 to 12 = 159 ppb o Females ages 13 to 49 = 180 ppb o General U.S. population = 204 ppb The human health risk assessment used both monitoring and modeling data to estimat e concentrations and focused on fiveregions where simazine is used – the Midwest (corn), the Mid - Atlantic ( corn and fruit trees ), Washington (fruit trees ), California ( nuts, fruit trees , and citrus ), and Florida (citrus). Monitoring data were used to ide ntify maximum peak, 90 - day average, and annual average concentrations of simazine for the Midwest, the Mid - Atlantic, and Washington. Monitoring data for simazine are available from the Population - Linked Exposure Database (PLEX), which contains data initia lly collected to comply with monitoring requirements in SDWA, and from the registrant - supported monitoring programs Voluntary Monitoring Program (VMP) and Atrazine Monitoring Program (AMP). PLEX includes measurements taken primarily on a quarterly basis ( i.e., a maximum of four per year) for concentrations of simazine only in finished (treated) water in CWS with both surface and ground water sources. The VMP/AMP database includes morefrequent measurements for concentrations of simazine and its two chlori nated degradates in both raw and finished water in select CWS where there is a history of atrazine use. The Agency used a simple linear regression analysis to derive an equation representing the relationship between the sum of the parent compound (simazin e) plus its two chlorinated degradates and levels of the parent compound alone. The regress ion equation is �(s imazine + DACT + DIA) = 0.364 + 1.378 * (s imazine). This analysis allowed EPA to derive conservative estimates of concentrations for total simaz ine plus its two chlorinated degradates when thesedata were not available in the databases.

### Estimated maximum peak, 90 - day average, and annual average concentrations of simazine in surface water for California and Florida were generated using the predi ctive model Pesticide Root Zone Mode / Exposure Analysis Modeling System ( PRZM/EXAMS) because sufficient monitoring data werenot available for areas where simazine use is most intensive in these states. PLEX contains infrequent and sparse measurements fro m California and Florida and the VMP/AMP database does not include measurements from these states. Modeling was performed to estimate concentrations in drinking water derived from surface water s ources which might occur near nut, fruit tree , and citrus growing areas of these regions as well as nationwide, representing the three sites with the highest simazine use in California and Florida. The mo deled scenarios include the following and are listed in Table 3 : almonds in California with a banded applicatio n rate (where the pesticide is applied to the field in bands or rows rather than broadcast ) to represent use at this application rate on nuts in California ; a second scenario for almonds in California with a higher broadcast application rate and a separate scenario for pecans and other nuts in Georgia (an area of more abundant rainfall) with a broadcast application rate, both scenarios together representing use on nuts grown nationwide including macadamia nut production in Hawaiiand California ; fruit in Ca lifornia with a banded application rateto represent use at this application rate on fruit tree s (apples, cherries, nectarines, peaches , pears, and plums) in California ; a second scenario for fruit in California with a higher broadcast application rate and a separate scenario for peaches in Georgia with a broadcast application rate, both scenarios together representing use on fruit tree s grown nationwide; citrus in California with a broadcast application rate ; and citrus in Florida with a broadcast applicat ion rate . As with monitoring data, the Agency used an equation representing the relationship between the sum of the parent compound (simazine) plus its two chlorinated degradates and levels of the parent compound alone to derive conservative estimates of concentrations for total simazine plus its two chlorinated degradates. Modeling was also performed to provide estimates of simazine concentrations in ground water using the Screening Concentration in Ground Water model or SCI- GROW2 . SCIGROW2 provides es timated concentrations of the parent compound when the pesticide is used at a high application rate in areas where ground water is vulnerable to contamination. Estimates for use on citrus in Florida and citrus and grapes in Texas were generated. The Agen cy does not believe that the equation used to derive estimates of concentrations for total simazine plus its two chlorinated degradates in surface water can be reliably used for ground water, so only concentrations of the parent compound were estimated for ground water.

Page 21 of 266

### The Agency considere d data from USDA’s PDP , EPA’s Chesapeake Bay Program , and the U.S. Geological Survey’s National Water - Qua lity Assessment Program (NAWQA) , as well as data from the states of California and Florida, to characterize results from both monitoring and modeling data. The data demonstrate that ambient concentrations are capable of reaching high levels under the proper combination of application timing and climatic conditions although indications of theseconcentrations w ere not evident in PLEX or V MP/A MP. The Agency also considered data from the Rural Well Survey that was submitted during atrazine’s reregistration process to further address rural wells, a ground water source of drinking water of particular importance in Florida. In the Rural Well Survey, measurements of simazine were taken once from each of 402 wells across seven states and ranged up to 11 ppb for the parent compound (simazine) alone . N o surfaceor ground water concentrations generated from either monitoring or modeling data exceed the acute DWLOC; therefore, acute exposure to simazine plus its two chlorinated degradates in drinking water is below the Agency’s level of concern . No CWS in the Midwest with a ground water source was identified in the available mon itoring data with concentrations that indicate the system may exceed the chronic DWLOC for infants and children less than 1 year old , the most sensitive subpopulation . However, one CWS in the Midwest with a surface water source, Hillsboro CWS of Illinois, had a maximum 90 ­ day average concentration in 1994 of 25.2 ppb simazine plus its two chlorinated degradates, indicating the system may exceed the chronic DWLOC for infants and children less than 1 year old . While the human health risk assessment also ide ntifies Defiance City CWS of Ohio as having a concentration of concern, upon further review of the monitoring data, the Agency has concluded that the maximum 90 - day average concentration is lower than previously calculated, and no concentrations for this C WS are of concern to the Agency. No surface or ground water CWS in the Mid - Atlantic or Washington were identified in the monitoring data with concentrations indicating a potential exceedance of the chronic DWLOC for infants and children less than 1 year o ld . M odeled surface water concentrations exceed the chronic DWLOC for infants and children and are of concern to the Agency for the following uses: nuts (mainly in California and Hawaii) when simazine is applied at a broadcast rate of 4 pounds active ing redient per acre (lbs ai/A) ; fruit tree s (apples, cherries, nectarines, peaches, pears, and plums) in states other than California when applied at a broadcast rate of 4 lbs ai/A or higher; and citrus in Florida when simazine is applied at a broadcast rate of 9.6 lbs ai/A . Table 3 below presents all modeled scenarios with those concentrations bolded that exceed the chronic DWLOC of 3 7.5 ppb for infants and chil dren less than 1 year old and/or 69 ppb for children ages 1 to 6 . Modeled surface water concentr ations do not exceed the chronic DWLOC for any subpopulation, including infants and children less than 1 year old , for use on nuts when simazine is applied at a banded rate of 2 lbs ai/A ; for use on fruit tree s when simazine is applied at a banded rate of 2 lbs ai/A or when applied at a broadcast rate of 4 lbs ai/A in California ; and for use on citrus in California when simazine is applied at a broadcast rate of 4 lbs ai/A . Page 22 of 266

### Modeled ground water concentrations of the parent compound ( simazine ) alone also d o not exceed the chronic DWLOC for any subpopulation, including infants and children less than 1 year old, for high rate uses in Florida (9.6 lbs ai/A on citrus = 11.7 ppb simazine) or Texas (4.8 lbs ai/A on grapes or citrus = 5.9 ppb simazine ). An addit ional national use that was not modeled but is also expected to exceed the chronic DWLOC of 204 ppb for the general U.S. population based on an application rate of 40 lbs ai/A, or a rate four times as high as the highest rate modeled, is nonselective weed control on noncrop land. This application rate is expected to produce modeled concentrations that are at least 4 times higher, and possibly much higher, than those for use on citrus in Florida. This use site includes, for instance, industrial sites, high way medians and shoulders, and noncrop areas around farms such as around buildings.

### 4 . Residential Exposure and Risk Residential risk is expressed as a Margin of Exposure (MOE) which reflects a determination of how close the residential exposure comes to the NOAEL determined in toxicity studies on animals. For simazine , a neuroendocrine endpoint was identified for short - term exposure based on an adverse effect of delayed preput ial separation observed in a pubertal study on male rats exposed to atrazine. Neuroendocrine effects such as this are the primary toxicological effects of regulatory concern for simazine. The NOAEL determined for short - term exposure is 6.25 mg/kg/day. T he MOE level of concern includes a n uncertainty factor of 100X which includes 10X each for intraspecies variability ( i.e., differences among humans) and interspecies extrapolation ( i.e., uncertainty in extrapolating from animal data to humans ). T he total FQPA safety factor applied to the residential assessment for simazine was reduced from the default 10X FQPA safety factor to 3X . A 3X FQPA safety fac tor was retained to account for residual uncertainty regarding the effects of the neuroendocrine mechanism of action on the developing child. The Agency determined that it was unnecessary to retain an additional FQPA safety factor in the residential assessment to ac count for exposure - based uncertainty because the assessment is based on EPA’s Standard Operatin g Procedures using high - end default values and assumptions that would be protective of infants and children . For simazine, a short - term MOE of 300 or greater is b elow EPA’s level of concern. Simazine is registered for residential use on turfgrass includ ing both commercial use on recreational lawns such as golf courses and commercial or homeowner use on home lawns . Simazine is also registered for use in ornamental ponds and aquariums of 1,000 gallons or less. Risks were calculated , based on exposure to the parent compound (simazine) alone, for homeowner h andler tasks for dermal and inhalation routes of exposure . Risks were similarly calculated for adults, youths (children ages 7 to 12) , and toddlers (children ages 1 to 6) entering areas of turfgrass after application of simazine ( post - application ) for the dermal route of exposure. Post - application risk for toddlers was also calculated for the incidental oral route of exposure. Exposure in all of these scenarios is expected to be short - term only . Derma l and inhalation absorption rates of 6% and 100% , respectively, as well as maximum application rates and estimates of what area homeowners would typically treat in a day , were assumedfor each scenario assessed. Page 24 of 266

### Of the four homeowner handler scenarios as sessed, one results in a risk that exceed s the Agency’s level of concern. The task of loading/applying granules via a belly grinder to turfgrass when simazine is applied at a rate of 1.75 lbs ai/A results in a n MOE of 76 for short - term derma l exposure. W hen dermal exposure and inhalation exposure are combined for this scenario, the MOE that results is 75. For the post - application scenarios assessed for toddler s , youths, and adults , no risk s exceed the Agency ’s level of concern (i.e., all MOEs are greater than or equal to 300) . 5 . Aggregate Exposure and Risk In accord ance with FQPA, the Agency consider s and a ggregate s pesticide exposures and risks for dietary exposure (from both food and drinking wate r) as well as residential exposureif applicable . Based on a common endpoint of toxicity, acute, short - term, intermediate - term, and chronic risk from dermal, inhalation, and oral routes of exposure may be aggregated. Because dietary exposure to simazine from food is estimated to be zero, aggregate risks for simazine are driven by dietary exposure from drinking water and/ or residential exposure. Risk estimates for aggregate acute exposureare based on acute dietary exposure from drinking water only. As d iscussed above, n o surfaceor ground water concentrations generated from either monitoring or modeling data exceed the acute DWLOC or the Agency’s level of concern; therefore, acute exposure to simazine plus its two chlorinated degradates in drinking water is below the Agency’s level of concern . Risk estimates for aggregate acute exposures to simazine and its two chlorinated degradates are also, therefore, below the Agency’s level of concern. Risk estimates for residential handlers from aggregate short - term exposure to simazine and its two chlorinated degradates are based on short - term residential exposurefrom the dermal and inhalation routes of exposure as well as chronic drinking water exposure. Risk estimates for adults, youth s , and toddlers entering treated areas of turfgrass post - application from aggregate short - term exposure are based on short - term residential exposure from the dermal and incidental oral (where applicable) routes of exposure as well as ch ronic drinking water exposure. EPA did not a ggregate short - term residential exposures with dietary exposure from drinking water for those residential exposure scenarios with risk estimates already above EPA’s level of concern. This applies to the MOE calculated for (adult) handlers loading/applying granules via a belly grinder to turfgrass , which is above the Agency’s level of concern based on residential exposure only . However, the Agency did aggregate exposures when residential exposure alone was not above EPA’s level of concern. No additional r isk estimate s for residential handlers from aggregate short - term exposure to simazine and its two chlorinated degradates exceed the Agency’s level of concern. Risk estimates for adults and youths entering treated areas of turfgrass post - application from a ggregate short - term exposure also do not exceed the Agency’s level of concern. However, risk estimates for toddlers entering treated areas of turfgrass post - application are of concern to the Agency when drinking water exposure is aggregated with short - ter m residential exposure. Page 25 of 266

### The MOE calculated for toddlers entering treated areas of turfgrass post - application does not exceed the Agency’s level of concern (i.e., is not below 300) based on short - term residential exposureonly ; however, modeled concentrati ons of simazine plus its two chlorinated degradates exceed the Agency’s level of concern for toddlers in those scenarios noted above. Aggregating the two exposures, therefore, yields risk estimates above the Agency’s level of concern. Risk estimates for aggregate intermediate - term and chronic exposure are based on chronic dietary exposure from drinking water only as there is no residential exposu re for these exposure durations. Risk estimates are of concern to infants, toddlers, and the general U.S. popu lation for those scenarios previously noted. 6 . Occupational Exposure and Risk Aswith residential exposure, occupational risk is expressed as an MOE. For simazine, a neuroendocrine endpoint was i dentified for short - term exposure based on an adverse effect of delayed preputial separation observed in a pubertal study on male rats exposed to atrazine. A neuroendocrine endpoint was also identified for intermediate - term exposure based on adverse effec ts of estrous cycle alterations and LH surge suppression observed in a n LH surge study on female rats exposed to atrazine. Neuroendocrine effects such as these are the primary toxicological effects of regulatory concern for simazine. The NOAEL determinedfor short- term exposure is 6.25 mg/kg/day and the NOAEL determined for intermediate - term exposure is 1.8 mg/kg/day. The MOE level of concern includes an uncertainty factor of 100X which includes 10X each for intraspecies variability ( i.e., differences am ong humans) and interspecies extrapolation (i.e., uncertainty in extrapolating from animal data to humans ). In the case of simazine, a short - term or intermediate - term MOE of 100 or greater from dermal and inhalation routes of exposure is not of concern to the Agency. Occupational exposure and risk are estimated for handlers (mixers / loaders, applicators, flaggers , and mixer/loader/applicators ) and re - entry workers who could be exposed when entering a treated area post - application to perform crop - productio n tasks. For simazine, occupational exposure may be shortor intermediate - term, but it is not expected to be long - term. Occupational exposure is expected to include the parent compound (simazine) alone . Dermal and inhalation absorption rates of 6% and 10 0% , respectively, as well as maximum application rates and the number of acres that can be reasonably treated in a day , were assumedfor each scenario assessed. Based on a common endpoint of toxicity , dermal and inhalation exposure were combined in the ca lculation of risk . a. Handler Exposure and Risk Estimates of exposure for occupational handlers are based on the activity, the formulation type, the application method, and the clothing worn, and are normalized by the amount of pesticide handled for the particular activity . T he MOE s for occupational handlers are also calculated at different levels of risk mitigation. Typically, the Agency uses a tiered approach with the lowest tier designated as bas eline exposure . Baselineassumes the occupational handler is wearing a long- sleeve shirt, long pants, socks, and shoes but no personal protective equipment (PPE), such as gloves or a respirator. If risks are of concern at baseline, then increasing levels of Page 26 of 266

### PPE (e.g. , double layer clothing such as coveralls, gloves , respirators) a re evaluated. If risks remain of concern with maximum PPE, then engineering controls (e.g., water - soluble packaging, closed mixing/loading systems , enclosed cabs or cockpits) are evaluated . For simazine the following occupational handler scenarios were assessedat various levels of risk mitigation: • Mixer/Loaders: o (1a) Liquids for Aerial Applications o (1b) Liquids for Chemigation Applications o (1c) Liquids for Groundboom Applicati ons o (1d) Liquids for Rights - of - way Applications o (1e) Liquids to Support L awn Care Operator Handgun Applications o (2a) Wettable Powder for Aerial Applications o (2b) Wettable Powder for Groundboom Applications o (2 c ) Wettable Powder for Chemigation Applications o (2d) Wettable Powder for Rights - of - way Applications o (2e) Wettable Powder to Support L awn Care Op erat or

### For the 32 occupational handler scenarios assessed, most short - term MOEs are not of concern to the Agency when some level of risk mitigation is considered . However, for 6 scenarios , sho rt- term MOEs are of concern to the Agency even with maximum feasible risk mitigation included . For 18 scenarios , intermediate - term MOEs are of concern to the Agency, even with maximum feasible risk mitigation included . Potential risks of concern exist particularly for those scenarios with relatively high acres treated (e.g., use on corn) or relatively high maximum application rates (e.g., use on rights - of - way, representing use as nonselective weed control on non - crop land) . Tables 4 and 5 below present those scenarios for which MOEs remain below 100 with maximum risk mitigation feasible for those scenarios taken into account.

### b. Post - Application Exposure and Risk For re - entry wo rkers, exposure estimates are based on the types of tasks and activities that individuals are likely to be doing in areas recently treated with a pesticide. Estimates of exposure are calculated using transfer coefficients, a standard measure of contact wi th treated foliage or other surfaces an individual would have while doing a specific task , and chemicalspecific calculations of dislodgeable foliar residue, or the amount of pesticide available on the leaf surface that can potentially be transferred to th e skin of an individual in contact with the treated surface. Increasing levels of PPE is not considered a viable a pproach for mitigating post application risks so PPE is not used when calculating MOEs for re - entry workers; instead, the MOE is calculated f or various intervals (by increasing the number of hours or days) after application. For post - application exposure, risks from simazine applied at a rate of 4 pounds active ingredient per acre (lbs ai/A) are not of concern approximately 12 hours after appl ication for those scenarios assessed that have relatively low transfer coefficients . However, for activities with relatively high transfer coefficients, MOEs exceed the Agency’s level of concern for dermal Page 30 of 266

### exposure until 2 days, or 48 hours, after appl ication . These activities include pruning, training, topping, or staking Christmas trees; and harvesting, transplanting, and weeding turfgrass (unless the product is watered in). 7 . Human Incident Summary Databases consulted for the incident report for simazine include the OPP Incident Data System (IDS), Poison Control Centers, California Department of Pesticide Regulation, and National Pesticide Telecommunications Network (NPTN). T he Agency concludes that s imazine can be a skin or eye irritant from direct exposures based on the following incidents . A total of 21 incidents were reported in the OPP IDS . Many of these incidents inv o lved irritant effects to the eyes, skin and respiratory passages and several in volved general central nervous system effects (e.g., nausea, dizziness, headache, restlessness). Poison Control Incident data (1993 - 2001) indicated that simazine appears to be much less acut ely toxic than other pesticides . The overwhelming majority of sy mptoms reported due to simazine exposure were eye, dermal, and throat irritation. 74 cases involving simazine were report edto the California Pesticide Illness Surveillance Program from 1982 - 1999 . Nine of these cases either involved the use of simazine a lone or were cases in which simazine was judged to be primarily responsible for the health effects. Given simazine’s widespread use in California, relatively few cases of simazine illness were reported. B. Ecological Risk Assessment To estimate potential ecological risks to non - target organisms, EPA integrates the results of exposure and ecotoxicity studies using the deterministic risk quotient method. Risk quotients (RQs) are calculated by dividing estimated exposure concentrations (EECs) by acute and chronic ecotoxicity values for species identified as representative of a broad taxonomic group of aquatic or

terrestrial organisms. EECs are generally based on maximum application rates for the pesticide and can be determined through monitoring studies or modeling. Ecotoxicity values are determined from r egistrant - submitted studies or studies available in open literature. Acute ecotoxicity values reflect the doses or concentrations that, in an acute toxi city study, are lethal to 50% of the test animals in the group, or cause other similarly severe effects (e.g., immobilization). On an acute basis, sima zine is non - toxic to estuarine/marine fish and invertebrates at the limits of its water solubility; prac tically non - toxic to birds, mammals, and honeybees; moderately toxic to freshwater fish; and highly toxic to freshwater invertebrates. Chronic ecotoxicity values reflect the doses or concentrations that , in an early - life or full - life stage study involving fish and aquatic invertebrates or a reproductive study involving birds and mammals, are representative of the highest “ no observed adverse e ffect concentration ” or NOAEC. For sim azine, the chronic effects in birds are based on reproductive endpoints ( a d ecrease in the number of eggs laid ) ; in mammals, chronic effects are based reduced body weight gain. Calculated RQs are compared to the Agency’s levels of concern (LOCs), which are standard threshold values across all pesticides. There is potential risk if the RQ value exceeds an LOC, and in general the higher the RQ, the greater the potential risk. Risk characterization Page 31 of 266

### provides further information on the likelihood of adverse effects occurring by considering the fate of the chemical in the environment, communities and species potentially at risk, their spatial and temporal distributions, t he nature of the effects observed in studies , as well as the existence of reported incidents to non - target organisms as a potential result of use of the pesticide. Ri sk characterization for simazine has included all but an examination of the spatial and temporal distributions of the communities and species potentially at risk. Table 6 below lists the LOCs that the Agency used to determine ecological risk from pesticid e use . The ecological assessment considers exposure to the parent compound (simazine) only. Available effects data on the degradates of simazine for mammals and non - vascular plants indicate they have a toxicity equal to or less than the parent compound, but effects data are not available for other taxonomic groups. Available laboratory and monitoring data indicate that the three degradates of simazine that are commonly seen in the laboratory studies, DIA , DACT , and hydroxy - simazine, will not be formed inthe environment at levels that could signi ficantly impact aquatic and terrestrial organisms. Simazine’s use in ornamental ponds and aquariums is not considered as part of the ecological risk assessment because, as of 1996, labels on end - use product s cont aining simazine prohibit direct discharge into ponds or aquariums larger than 1,000 gallons, as well as application or discharge into lakes, flowing water, or ponds with outflow. The Agency estimated ecological risks from both non - granular and granular fo rmulations of simazine for non - target aquatic and terrestrial organisms, including freshwater fish and invertebrates, estuarine/marine fish and invertebrates, vascular and non - vascular aquatic plants, birds, mammals, and monocot and dicot terrestrial plant s. A preliminary assessment wa s also completed for Federally L isted T hreatened and E ndangered Species (Listed Species) . Based on the mobility and persistence of simazine, simazine’s mode of action, and the potential dietary exposure to simazine of aquati c and terrestrial organisms , the risk hypothesis of the ecological risk assessment presumes that simazine has the potential to cause reduced survival, and reproductive and growth impairment for both aquatic and terrestrial animal and plant species.

### 1. Environmental Fate and Transport Simazine is mod erately soluble (solubility of 3.5 mg/L) in water at 20°C or 68°F. However, simazine’s solubility may increase with temperature, reaching 17 mg/L at 50°C or 122°F. Laboratory studies indicate that simazine is persistent, able to persist for months in the environment ( half - life of 91 days) and possibly years in oxygen - deprived aquatic systems (halflife of 664 days) as it is not easily degraded by soil microbial organisms. If simazine is released at the soil surface and under direct sunlight, it undergoes relatively faster degradation (half - life of 22 days). Simazine is also quite resistant to aqueous abiotic reactions (e.g., hydrolysis and photolysis), increasing its likelihood to be present in stormwater runoff and to contaminate surface water. Aquatic field studies indicate variable persistence ranging from 12 days to 700 days. The limited number of terrestrial field studies available indicate that simazine could persist in the field for over one month to several years depending on soil texture and so il temperature. Laboratory absorption data show low water/soil partitioning for simazine, or ability to be absorbed into the soil. These data indicate that simazine is highly mobile and has a strong potential to leach into ground water systems, especiall y in soils low in organic matters such sandy soils. Volatilization losses of simazine from soil and water systems are expected to be insignificant compared to dissipation by chemical degradation and metabolism. Simazine also has a low potential to bioacc umulate in fish. The persistence and mobility of simazine, as demonstrated by the laboratory data, suggest that the chemical could reach surface water via transport from soil surfaces during runoff events and ground water via leaching, or vertical movemen t through soil . The greatest contribution to EECs in water is runoff, particularly in states where precipitation is a major factor in runoff such as in the Southeast (e.g., Florida) and the Midwest (e.g., Illinois, Missouri). However, spray drift plays a greater role in exposure in the Pacific coastal region (e.g., California, Oregon ). S imazine’s chlorinated degradates DIA and DACT are shown in studies to be more mobile than simazine, and thereforemore likely to leach to ground water than the parent com pound. Hydroxy- atrazine, on the other hand, is less mobile than simazine, and has less leaching poten tial than the parent compound. Based on data from the registrant - supported drinking water monitoring programs VMP and AMP, and the concentration of simaz ine’s chlorinated degradates in CWS where both simazine and atrazine are detected compared to those with only atrazine detections, the Agency is confident that DIA and DACT derived from simazine have the potential to reach surface water , but not at levels that could significantly impact non - target organisms .

### 2. Aquatic Organism Exposure and Risk While several sources of monitoring data, including the VMP/AMP database, were used to understand the p otential concentrations of simazi ne in surface water, EECs were estimatedfor aquatic organism risk calculations using the predictive model PRZM/EXAMS. Most of the monitoring data available were not designed to specifically target areas of intense simazin e use and since the sampling designs (e.g., frequency of monitoring) were not intended to capture peak pesticide concentrations, there is high likelihood they may have been missed. The modeled EECs are considered protective upper bound estimates for the a quatic organism risk calculations, as were modeled concentrations in drinking water for dietary human health risk, while the monitoring data provide lower bound estimates. In order to characterize potential ecological risk to aquatic organisms, ten crops were selected to represent the primary uses of simazine. These crops include turf (representing use as nonselective weed control on non - crop land), citrus, apples, caneberries, corn, pine trees (Christmas trees), grapes, nuts, corn, fruit (peaches and nec tarines), and lettuce (a s a surrogate for strawberries) . A variety of different scenarios were simulated across the selection of crops in order to account for different geographical locations both specified by the labels and based on agricultural practice s, with locations concentrated in areas with intense simazine use. Crop scenarios also included variable spray drift assumptions of 0% to 5% to gauge the contribution of drift to runoff and consequently EECs. Acute RQs calculated for freshwater fish and invertebrates do not exceed the LOC of 0.5 for acute risk. However, there is a high degree of uncertainty associated with the acute freshwater data set because exposure concentrations were not verified in the available acute toxicity tests. Additionally, the results of future studies on atrazine’s potential sublethal effects to amphibians, specifically impacts on gonadal development in frogs, may be applicable to simazine because the two chemicals share a similar neuroendocrine mechanism of toxicity, a si milar mechanism of herbicidal action, and the same degradates. However, ecotoxicity data on the sublethal effects of simazine to amphibians, a taxonomic group for which freshwater fish data generally substitutes , are currently not available. Acute RQs were not calculated for estuarine/marine fish and invertebrate s because a cute toxicity data shows that simazine is not likely to be acutely toxic to either estuarine/marine fish or invertebrates at the limits of its water solubility. Potential chronic effec ts for both freshwater and marine/estuarine fish and invertebrates are unknown because chronic toxicity data on the technical grade active ingredient for these taxonomic groups are also not available . A freshwater fish early life - cycle test with fathead m

innow and a freshwater aquatic invertebrate life - cycle test were submitted for a simazine formulation of 80% active ingredient that indicate the formulation is unlikely to exceed the Agency’s LOC of 1.0 for chronic risk . However, a cute toxicity data indic ate that the technical grade active ingredient may be more toxic to fish than the 80% formulation.

Page 34 of 266

### Many of the calculated acute RQs for vascular and non - vascular aquatic plants exceed the LOC of 1.0 for acute risk, and indicate that there is the potenti al for direct adverse acute e ffects from both non - granular and granular formulations, especially for non - vascular plants (e.g., a variety of blue green algae, A. flosaquae ) . RQs for vascular aquatic plants range from below the LOC to 2.4. RQs for non - vas cular aquatic plants range from below the LOC to 9.33. The Agency does not currently assess chronic risks to plants. T

wo important considerations relative to simazine’s potential to affect plants are recovery and potential resistance of some species. Re covery is possible following removal of simazine from the site of action, although there is uncertainty associated with the approximate length of time it takes for recovery to occur, given a certain level of exposure. While there is no major evidence that a clearly herbicide - resistant or tolerant community exists, available data suggest that periphytic blue - green algae, unlike the A. flosaquae variety which is sensitive to simazine, may be resistant at higher application rates. Periphytic blue - green algae ’s relative abundance when simazine is used at higher application rates suggests an important ecological shift that may potentially impact the aquatic community structure. Table 7 presents acute RQs calculated for aquatic organisms with those RQs bolded that exceed the Agency’s LOC of 1.0 for acute ecological risk to vascular and non - vascular aquatic plants.

### 3. Terrestrial Organism Exposure and Risk EECs were estimatedfor terrestrial organism risk calculations by estimating pesticide residue on food items for birds and m ammals, as well as estimating the loading of pesticide in granular formulations per unit of treated area using labeled application rates and intervals between applications. For spray applications of non - granular formulations, EECs were derived through mod eling for seven crop scenarios including citrus, pine trees, grapes, nuts, corn, almonds/fruit, and strawberries. For granular formulations, EECs were estimatedfor mammals and birds basedon an assumption that all of the granules are unincorporated in th e soil, and therefore available for consumption, and based on two possible routes of exposure, both directly through oral consumption of granules, and indirectly through consumption of terrestrial invertebrates that have bioaccumulate d pesticide residues. EECs for terrestrial plants were based on standard runoff and spray drift scenarios with inputs such as a pesticide’s water solubility, and are modeled for granular formulations assuming that granules are incorporated and unincorporated. Default spray dr ift assumptions are 1% for application on the ground and 5% for aerial application. That is 1% and 5% of the pesticide reaches a non - target area adjacent to a treated area based on respective ground and aerial applications. For terrestrial animals, poten tial ecological risks were characterized for the seven crop scenarios by comparing the EECs to ecotoxicity data. For terrestrial plants, potential ecological risks were determined using RQ estimates for dry and wetland areas adjacent to a treated site, as well as for areas impacted by spray drift. No acute RQs were generated for birds or mammals because definitive ecotoxicity values were not available. InsteadEECs were compared to the dose or concentration at which little or no mortality was observed. None of the EECs exceed or approach this dose for birds; therefore, avian mortality is unlikely from acute exposure to simazine . However, acute sublethal effects (e.g., reduced reaction to external stimuli, wing drop, depression) are possible from non - gra nular formulations. None of the EECs for mammals exceed or approach the dose at which mortality occurred; therefore, there is also a low likelihood of mortality to mammals from acute exposure to simazine . Page 37 of 266

### There is the potential for direct adverse chronic effects for both birds and mammals. A number of chronic RQs calculated for birds , based on a reproductive effect (reduction in the number of eggs laid), exceed the LOC of 1.0 for chronic risk from non - granular formulations . The same is true for mammals, b ased on reduced body weight gain , for both non - granular and granular formulations . Chronic RQs calculated for birds reach a maximum of 23. For nongranular formulations, c hronic RQs calculated for mammals reach a maximum of 230 and exceed 50 in five of t he seven crop scenarios modeled. For granular formulations, chronic RQs calculated for mammals associated with ingestion of earthworms that have bioaccumulated simazine range from 2 to 36. Table 8 below presents chronic RQs based on non - granular formulat ions calculated for birds and mammals with those RQs bolded that exceed the Agency’s LOC of 1.0 for chronic r isk As with aquatic plants, many of the calculated acute RQs for monocot and dicot terrestrial plants exceed the LOC of 1.0 for acute risk, and in dicate that there is the potential for direct adverse acute effects from both non - granular and granular formulations , with greater risk to emerging seedlings than emerged plants exposed via foliar spray . The Agency does not currently assess chronic risks to plants. Table 9 presents acute RQs calculated for monocot and dicot terrestrial plants with those RQs bolded that exceed the Agency’s LOC of 1.0 for acute risk.

### 4. Risk to Endangered Species For purposes of the REDfor simazine, the Agency completed a preliminary or screeninglevel asse ssment for Listed Species . The Agency has developed the Endangered Species Protection Program to identify pesticides whose use may cause adverse impacts on Listed Species and to implement mitigation measures to address these impacts. The Agency acknowled ges that pesticides have the potential to exert not only direct effects but indirect effects as well upon the Listed Species by, for example, perturbing forage or prey available, altering the extent of nesting habitat, etc. Acute and chronic RQs , which represent direct effects, for each taxonomic group are used to make inferences concerning the potential for indirect effects upon Listed Species that rely upon non - threatened and - endangered organisms in these taxonomic groups as resources critical to their life cycle. The greater the RQs for a taxonomic group, the greater concern for potential indirect effects for Listed Species dependent on that taxonomic group. Potential effects of pesticides on designated critical habitats for Listed Species are also in cluded and considered as potential indirect effects. Focus is given to the physical and biological features (constituent elements) of a critical habitat identified by the U.S. Fish and Wildlife and National Marine Fisheries Services as essential to the co nservation of a Listed Species and which may require special management consideration or protections. The Agency’s preliminary assessment indicates that the LOC for Listed Species is exceeded for the following combination of taxonom ic groups and uses: • Freshwater fish

–granular application for nonselective weed control on turf and other noncrop land ; • Freshwater invertebrates

–non - granular application on citrus, pine trees, nuts, peaches , and corn ; granular application for nonselec tive weed control on turf and other non - crop land as well as apples ; • V ascular aquatic plants

–non - granular application on citrus, nuts, peaches, and corn; granular application for nonselective weed control on turf and other non - crop land as well as apples ; • Birds

–non - granular application for all uses ; • Mammals

–non - granular and granular application for all uses ; and • Monocot and dicot terrestrial plants

–non - granular and granular application for all uses . Although RQs for vascular and non - vascular plant s exceed the LOC for Listed Species , there are no endangered species of non - vascular plants. Based on acute and chronic RQs, there are additional potential indirect effects to Listed Species that have the following behaviors: • Eat fish or amphibians (e.g., fish, mammals, birds, reptiles), or in the case of freshwater mussels, use a fish as a necessary host in their life cycle ; • Rely on freshwater invertebrates (e.g., daphnids) as a primarily food source; rely on aquatic plants for food and/or habitat and she lter ; • Eat birds or require birds as pollinators or seed dispersers ; • Eat mammals or require mammals as pollinators or seed dispersers ; and • Rely either on a specific plant species (plant species obligate) or multiple pla nt species (plant depende nt) for some important aspect of their life cycle . Page 40 of 266

### A total of 977 Listed Species may potentially occur in areas where simazine can be used. Table 10 lists the taxonomic groups and the direct toxicological effects of simazine on those taxonomic groups whose acute or c hronic RQs exceed the Agency’s LOC for ecological risk to Listed Species . Those RQs which e xceed the Agency’s LOC are bolded. Table 10. Taxonomic groups for which the Listed Species RQs exceed the Agency’s LOC

### Risks to endangered species identified in the ecological risk assessment for simazine are based solely on EPA’s screening level assessment and do not constitute “ may effect ” findings under the Endangered Species Act. Rather, this assessment serves as a screen to determine the need for any species spe cific assessments that will evaluate whether exposure may be at levels that could cause harm to specific Listed Species and their critical habitat. That assessment refines the screening- level assessment to take into account the geographic area of pestic ide use in relation to the Listed Species , the habits and habitat requirements of the Listed Species , etc. If the Agency’s specific assessments for atrazine result in the need to modify use of the pesticidein specific geographic areas , those changes to t he pesticide’s registration will take place through the process described in the Agency’s Federal Register Notice (54 FR 27984) regarding implementation of the Endangered Species Protection Program. 5. Ecological Incident Summary Incident data w erereviewed for aquatic and terrestrial organisms. Nine incidents for aquatic animals have been reported, all of which involved fish kills. Six of these incidents were reported with a certainty index of “ highly probable ” or “ probable ” in relation to causation by simazine and involved direct application to lakes, ponds, or lagoons. The additional three incidents were categorized as “ possible ” or unlikely ” and involved use of simazine along railroad tracks, on corn, and on an unspecified treatment site. All of the incidents occurred prior to 1996, when label language was clarified to prohibit direct discharge into ornamental ponds or aquariums larger than 1,000 gallons, as well as application or discharge into lak es, flowing water, or ponds with outflow . Page 41 of 266

### Two incid ents for terre strial animals and three incidents for terrestrial plants have been reported. An incident involving two dead quail in Yosemite National Park had a reported certainty index of “ unlikely ” in relation to causation by simazine, while another incident involving five Canada Geese in Virginia was categorized as “ probable. ” Three incidents involving terrestrial plants have been reported. One incident involved lawn damage from application to a sw imming pool, a use that has been cancelled, and the other two involved nontarget plant damage following aerial application on corn. IV. Risk Management and Reregistration Decision A . Determination o f Reregistration Eligibility Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after submission of relevant data concerning an active ingredient, whether or not products containing the active ingredient are eligible for reregistration. The Agency has previously identified and required the submission of th e generic ( technical grade) data required to support reregistration of products containing simazine as an active ingredient. The Agency has completed its review of these generic data, and has determined that the data would be sufficient t o support reregistration of all products containing simazine provided the registrations are amended in a manner consistent with this document . The Agency has completed its assessment of the dietary (both food and drinking water) , residential, occupational, and ecological risks associated with the use of pesticide products containing the active ingredient simazine . Based on a review of these data and on public comments on the Agency's assessments for the active ingredient simazine , the Agency has sufficient information on the human health and ecological effects of simazine to make decisions as part of the tolerance reassessme nt process under FFDCA and reregistration process under FIFRA, as amended by FQPA . The Agency has determined that products containing simazine are eligible for r eregistration provided that the risk mitigation measures outline d in this document are adopted and label amendments are made to reflect these measures. Specific label changes and language are specified in Section V . Appendix A provides a detailed tableof those uses eligible for reregistration . Appendix B identifies generic data requirements tha t the Agency reviewed as part of its determination of reregistration eligibility of simazine , and lists the submitted studies the Agency found acceptable. Data gaps are identified as either outstanding generic data requirements that have not been satisfie d with acceptable data or additional data requirements ne cessary to confirm the decision presented here. S hould a registrant fail to implement any of the risk mitigation measures identified in this document, the Agency may take appropriate regulatory acti on to address the risk concerns from the use of simazine. The Agency has also concluded that, with these mitigation measures and the mitigation measures in the atrazine IRED, the cumulative risk s associated with the c hlorinated triazine class of pesticide s, including simazine, arebelow the Agency’s level of concern. T herefore , i f all changes outlined in this document are incorporated into the product labels, then all current risks for simazine will be adequately addressedfor the purposes of this determi nation Page 42 of 266

### under FIFRA. O nce a comprehensiveendangered species assessment is completed, further changes to these registrations may be necessary as explained in Section IV.D.5 of this document. B. Public Comments and Responses Through the Agency's public participation process, EPA worked with stakeholders and the public to reach the seregulatory decisions for simazine . During the public comment period on the risk assessments, which closed on September 1 2 , 2005, the Agency received comments from California Department of Pesticide Regulation, American Water Works Association, University of Hawaii, Golf Course Superintendents Association, Triazine Network, Syngenta Crop Protection, Inc. ( a technical registr ant ), and Florida Department of Agriculture & Consumer Services . These comments expressed agreement with some portions of the risk assessments, argued that the risk assessment s used unnecessarily conservative assumptions at times, discussed the need for the availability of specific application rates and methods for particular uses of simazine, provided simazine usage statistics and described target weeds which simazine is used to control, and listed potential mitigation measures. These comments were revie wed and taken into consideration when the revised risk assessments and their supporting documents, in addition to this simazine RED, were completed. The comments are available in their entirety in the public docket EPA - HQ - OPP- 2005 - 0151 located on - line in FDMS http:// www.regulations.gov . The Agency's responses to substantive comments areavailable in memoranda in the public docket and the revised assessments available in the public docket reflect these responses . C. Regulatory Position 1. Food Quality Protection Act Findings a. “ Risk Cup ” Determination As part of the FQPA tolerance reassessment proc ess, EPA assessed the risks associated with simazine . The Agency has concludedthat, with the risk mitigation measures outlined in this document, the aggregate exposure to the pesticide simazine and its two chlorinated degradates (from food, drinking water, and residential sources) is within the “ risk cup. ” The Agency has determined that the human health risks from these combined exposures are within acceptable levels. In reaching this determination, EPA has considered the available information on the sp ecial sensitivity of infants and children. FQPA also requires the Agency to evaluate food tolerances on the basis of cumulative risk from substances sharing a common mechanism of toxicity, such as the neuroendocrine mechanism of toxicity shared by the structurally - related chlorinated triazines atrazine, simazine, propazine, and their three chlorinated degradates. The Agency hascomplete d itscumulative risk assessment for the chlorinated triazine class of pesticides and has concludedthat with the mitigat ion measures in this document and in the 2003 IRED for atrazine the cumulative risks associated with these pesticides are below the Agency’s level of concern. Page 43 of 266

### T he A gency has determined that tolerances for simazine meet the FQPA safety standards and are no w considered reassessed. b. Determination of Safety to U.S. Population (Including Infants and Children) The Agency has determinedt hat the established tol erances for simazine , with label amendments and changes as specified in this document, meet the safety standards under the FQPA amendments to S ection 408(b) (2) ( C ) and 408(b) (2)( D ) of the FFDCA, and that there is a reasonable certainty that no harm will res ult to the general U.S. population , infants, children, or other major identifiable subgroup s of consumers , from the use of simazine . The safety determination considers factors such as the toxicity, use practices and exposure scenarios , and environmental b ehavior of simazine. In determining whether or not infants and children are particularly susceptible to toxic effects from simazine residues, the Agency considered the completeness of the hazard database for developmental and reproductive effects, the na ture of the effects observed, and other information. The Agency determined it was unnecessary to retain a safety factor in the acute dietary assessment to account for hazard - based uncertainty because open literature data demonstrate that any neuroendocrin e effect, the primary toxicological effects of regulatory concern, that could result from a single dose would only occur at a very high dose. However, when available water monitoring data were used to estimate drinking water exposure, a 3X FQPA safety fac tor was retained to account for exposure - based uncertainty due to limitations in the monitoring database. The full 10X FQPA safety factor was retained and applied to the chronic dietary assessment to account for both exposure - based uncertainty in the water monitoring data and because of residual uncertainty regarding the effects of the neuroendocrine mechanism of action on the developing child. Wh en drinking water concentration values were estimated using modeling, which the Agency believes is conservativ e and protective, t he 3X for exposure - based uncertainty was unnecessary for inclusion in the chronic dietary assessment . T he total FQPA safety factor applied to the residential assessment for simazine was reduced from the default 10X FQPA safety factor to 3X. The Agency determined that it was unnecessary to retain a 3X FQPA safety factor in the residential assessment to account for exposure - based uncertainty because the assessment is based on EPA’s Standard Operating Pr ocedures using high - end default valu es and assumptions that would be protective of infants and children . A 3X FQPA safety factor was retained to account for hazard - based uncertainty . c. Endocrine Disruptor Effects EPA is required unde r the FFDCA, as amended by FQPA, to develop a screening program to determine whether certain substances (including all pesticide active and other ingredients) “ may have an effect in humans that is similar to an effect produced by a naturally occurring estr ogen, or other endocrine effects as t he Administrator may designate. ” Following recommendations of its Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC), EPA determined that there was a scientific basis for including, as part of the program, the androgen and thyroid hormone systems, in addition to the estrogen hormone system. EPA also adopted EDSTAC's recommendation that EPA include evaluations of Page 44 of 266

### potential effects in wildlife. For pesticides, EPA will use FIFRA and, to the extent tha t effects in wildlife may help determine whether a substance may have an effect in humans, FFDCA authority to require the wildlife evaluations. As the science develops and resources allow, screening for additional hormone systems may be added to the Endoc rine Disruptor Screening Program (EDSP). There is direct evi dence that simazine is associatedwith neuroendocrine disruption. Direct measurements of serum hormones such as certain steroid hormones and luteinizing hormone, as well as changes in estrus cy cling and histomorphic changes in hormone responsive tissues, indicate neuroendocrine disruption. EPA has responded, in part, to simazine’s known neuroendocrine disrupting capacity by regulating on endpoints based on neuroendo crine disruptor effects and requiring risk mitigation measures , label amendments, and additional confirmatory data to reduce potential risk s to below the Agency’s leve ls of concern . The Agency has determined that, with label amendments and changes as specified in this document, thereis a reasonable certainty that no harm will result to the general U.S. population, infants, children, or other major identifiable subgroup s of consumers , from the use of simazine. W hen the appropriatescreening and/or testing protocols being considered u nder the EDSP have been developed, simazine may be subject to additional screening and/or testing to better characterize effects related to endocrine disruption . d. Cumulative Risks FQPA stipulates that when de termining the safety of a pesticide chemical EPA shall base its assessment of the risk posed by the chemical on, among other things, available information concerning the cumulative effects to human health that may result from dietary, residential, or other non - occupational exposure to other substances that have a common mechanism of toxicity. The reason for consideration of other substances is due to the possibility that low - level exposures to multiple chemical substances that cause a common toxic effect b y a common mechanism could lead to the same adverse health effect as would a higher level of exposure to any of the other substances individually. A person exposed to a pesticide at a level that is considered safe may in fact experience harm if that perso n is also exposed to other substances that cause a common toxic effect by a mechanism common with that of the subject pesticide, even if the individual exposure levels to the other substances are also considered safe. For information regarding EPA's effor ts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the policy statements released by OPP concerning common mechanism determinations and procedures for cumulating effects from su bstances found to have a common mechanism on EPA's website at http://www.epa.gov/pesticides/cumulative . EPA evaluated simazine along with two other structurally - related chlorinated triazines, atrazine and propazine, and their three chlorinated degradates, as sharing a neuroendocrine mechanism of toxicity. After subchronic and chronic exposure to these compounds, a variety of species were shown to exhibit neuroendocrine effects resulting in both reproductive and developmental consequences that are consider ed relevant to humans. These compounds disrupt the hypothalamic - pituitary - gonadal (HPG) axis, part of the central nervous system, and cause Page 45 of 266

### cascading changes to hormone levels and developmental delays. The Agency has completed its cumulative risk assessm ent for the chlorinated triazine class of pesticides and has concluded that with the mitigation measures in this document and in the 2003 IRED for atrazine the cumulative risks associated with these pesticides arebelow the Agency’s level of concern. The Agency has determined that, with label amendments and changes as specified in this document and the 2003 IRED for atrazine , there is a reasonable certainty that no harm will result to the general U.S. population, infants, children, or other major identifia ble subgroup s of consumers , from the use of simazine, atrazine, and propazine. The cumulative risk assessment and supporting documents are available inthe public docket EPA - HQ - OPP - 2005 - 0481 located on - line in FDMS, http://www.regulations.gov . 2. Toler ance Summary A tolerance summa ry and tolerance reassessment decision is presented for simazine in Table 11 below. Currently there are 6 2 tolerances listed in 40 CFR 18 0 .213 for simazine on agricultural crops and animal commodities. With the exception of tolerances set for bananas and fish, tolerances for simazine residues are currently expressed in terms of the parent compound only. The Agency has determined that residues of concern in/on raw agricultural commod ities are simazine and its two chlorinated degradates, DIA and DACT . The Agency will propose changing t he tolerance expression for all commodities to reflect combined residues of the parent compound , simazine (2 - chloro - 4,6 - bis ( ethylamino) - s - triazine) , p lu s its two chlorinated degradates (2 - amino - 4 - chloro - 6 - ethylamino - s - tr i a zine and 2,4 - diamino - 6 - chloro - s - triazine) , the total residue to be measured in/on raw agricultural commodities for tolerance enforcement . The cropand animal commodity tolerances which the Agency will propose to revoke because the registrants are not supporting related use s include alfalfa, alfalfa (forage and hay) , Bermuda grass, Bermuda grass (forage and hay), fish, grass, grass (forage and hay), and sugarcane (molasses). The Agency intends to propose to revoke the tolerance for bananas as well because the registrants are not supporting use; however, available residue data may be appropriate to support a tolerance of 0.2 ppm if use is supported in the future . The Agency will also pro pose to revokethe following tolerances because there is no reasonable expectation of finding residues at quantifiable levels (40 CFR 180.6(a)(3)): cattle (fat), goat (fat), hog (fat, meat, and meat byproducts), horse (fat), poultry (fat, meat, and meat by products), and sheep (fat). Available residue data support lowering tolerances for avocado , blackberry, blueberry, corn ( forage and grain), filbert ( i.e., hazelnut ) , grape, loganberry, peach, plum, olive, and raspberry. Available residue data also support lowering tolerances for apples, provided a pre harvest interval is added to labels. The Agency will propose that tolerances for boysenberry and dewberry be reassigned (no longer listed as separate tolerances) because they are covered by the blackberry t olerance. Available residue data support increasing tolerances for pecan, cattle (meat and meat byproducts), goat (meat and meat byproducts), horse (meat and meat byproducts), milk, sheep (meat and meat byproducts), and egg . Available residue data supports maintaining the tolerance for corn (stover). Additional confirmatory residue data are necessary to support tolerances for almond, almond (hulls), cherry, corn (sweet), cranberry, currant, grapefruit, lemon, macadamia nut, orange, pear, strawberry, and walnut . However, there are no dietary (from food Page 46 of 266

### or drinking water) risk concerns associated with these 13 tolerances, and the Agency considers them reassessed at the current tolerance level. Tolerances will beproposed, and additional data are necessary , for citrus oil and rotational crops. No maximum residue limits (MRLs) for simazine have been established or proposed by Codex for any agricultural commodity. Canada doesnot currently have MRLs for simazine. Table 11 .

### D. Regulatory Rationale The Agency has determ ined that simazine is eligible for reregistration provided that the risk mitigation measures outlined in this document are adopted and label amendments are made to reflect these measures. T he following is a summary of the risk mitigation measures and EPA’ s rationale for the decision for managing risks associated with the use of simazine . Where labeling revisions are warranted, label changes and language are presented in Section V. 1. Human Health Risk Management and Mitigation a. Dietary Risk Mitigation ( Food and D rinking W ater) As discussedin Sections III.A.2 and 3, acute dietary risks (from food and drinki ng water) do not exceed the Agency’s level of concern. Additionally, chronic risks from food alon edo not exceed the Agency’s level of concern. There are potential chronic risks of concern to infants and children less than 1 year old , however, from drink ing water from one surface water CWS in the Midwest where sim azine is primarily used on corn. The following uses of simazine also present potential chronic risks of concern to infants and children (from less than 1 year old to 6 years old ) from drinking w ater exposure : use on nuts (mainly in California and Hawaii) when applied at a non - banded rate of 4 pounds active ingredient per acre (lbs ai/A) ; use on fruit trees (apples, cherries, nectarines, peaches, pears, and plums) in states other than California w hen applied at a non - band ed rate of 4 lbs ai/A or higher; and use on citrus in Florida when applied at a rate of 9.6 lbs ai/A . An additional use that potentially result s in concentrations that exceed the level of concern for the general U.S. population is “ non - selective weed control on non - crop land. ” To reduce human exposure to simazine and its two chlorinated degradates from drinking water and to address subsequent risks of concern , the following mitigation measures are necessary : • prohibit use as “ non - s elective weed control on non - crop land ” on product label s ; • prohibit aerial application and add a statement to productlabel s indicating this prohibition ; and • reduce maximum application rates to typical rates (as specified in Section V , Table 13 ) and harmon ize application rates on simazine product labels . Page 49 of 266

### Additionally, the Agency has discussed with the registrants the addition to simazine product labels of setbacks f rom wells and waterways in addition to restrictions for use in tile outletted terraced fields containing standpipes. These setbacks and use restrictions were previously instituted for atrazine to reduce water contamination, and will do the same for simazine plus have an overall effect of reducing drinking water exposure to simazine and its chlori nated degradates. A s further d etailed in Section V, Table 13, the following setbacks and use prohibitions will be added to simazine product labels for uses under the Worker Protection Standard for Agricultural Pesticides (WPS) and non - WPS commercial uses (as further detailed in Section V, Table 13): • prohibit use, mixing, and loading within 50 feet of all wells, including abandoned wells, drainage wells, and sink holes; • prohibit mixing and loading with 50 feet of intermittent streams and rivers, natural or impounded lakes and reservoirs; • prohibit application within 66 feet of points where field surface water runoff enters perennial or intermittent streams and rivers (if applied to highly erodible land, the buffer must be planted to the crop or seeded with gr ass or other suitable crop); • prohibit application within 200 feet of natural or impounded lakes and reservoirs; and • prohibit application to tile - outletted terraced fields containing standpipes within 66 feet of standpipes unless either immediately incorpo rated to a depth of 2 - 3 inches in the entire field or applied under a no - till practice when a high crop residue management practice is practiced (high crop residue management is described as a crop management practice where little or no crop residue is rem oved f ro m the field during or after crop harvest). The Agency also has received requests from the simazine technical registrants to amend the terms and conditions of registration for their manufacturing- use products (MUP s ) to require a surface water CWS m onitoring program with mitigation measure triggers . EPA intends to grant these amendments and to require the monitoring program as part of the confirmatory data to be called - in for simazine. The monitoring program will involve frequent monitoring at any CWS with a surface water source for which there is monitoring data indicating the concentration of simazine plus its two chlorinated degradates exceed s , or is predicted to exceed, the chronic DWLOC for infants and ch ildren , 12.5 ppb total . Six CWS, listedbelow, have been identified for immediate inclusion in the monitoring program, and additional CWS may be identified in the future for inclusion based on SDWA data or other reliable monitoring data. CWS with a ground water source will not be a part of this monitoring requirement at this time because, as discussed in Section III .A.3 , no ground water CWS were identified with concentrations indicating risks of concern . If concentrations of simazine plus its two chlorinated degradates at any surface water CWS meet or exceed the Agency’s level of concern or performance standard , th e n additional m

itigat ion measures will berequired at the associated watershed(s) . Further d etails of the program are explained below , and a copy of the letter technical registrants completed and submitted to amend the terms and conditions of registration for their MUP s is included as Appendix J . Page 50 of 266

### As with atrazine, e xceedances do not appear to be linked to nation - wide use practices that can be amended on the label but rather to watersh ed characteristics and local conditions . Based on simazine monitoring data, the Agency has determined that drinking water risks from simazine use are localized problems and, as such, lend themselves to a localized mitigation plan. This localized mitigati on program will ensure that mitigation actions taken in watersheds of concern are providing results in raw drinking water and will prevent any exceedances from occurring or going undetected in the future. In addition, this localized approach is consistent with both the conclusions from a February 2000 FIFRA Scientific Advisory Panel meeting (Partial Report May 25, 2000 . Report Number 2000 - 01) as well as with the intent of the Agency’s J anuary 2003 Water Quality Trading Policy . This policy encourages solu tions within watershed s , provides incentives and encourages actions, and provides flexibility to meet local challenges and accountability to ensure improvements. The localized drinking water mitigation program allows the Agency to make a safety finding be cause any future exceedances in raw water will trigger localized use prohibitions in the watershed of concern. Since this exceedance is in raw, not finished, water, treatment of water by CWS operators to meet the MCL may prevent actual exposure above the Agency’s level of concern. In addition, the Agency does not expect future exceedances to occur because of the responsible use program s being implemented and coordinated for atrazine by the simazine technical registrants, all of whom are also technical reg istrants for atrazine. Simazine usage data available to the Agency indicates that a majority of simazine used in the Midwest is tank mixed with atrazine, and, therefore, these responsible use programs would consequently impact the use of simazine as well. The Agency feels that the risk of localized use prohibitions is a strong incentive for simazine users and registrants to prevent exceedances. The performance standard approach makes the prevention of simazine water contamination the responsibility of th e user, but compliance is assured through EPA oversight of the intensive monitoring program. i. Simazine Surface Water CWS Monitoring Program For the surface water CWS monitoring progra m, the Agency used the 12.5 ppb chronic DWLOC for infants and children less than 1 year old, the most sensitive subpopulation, to identify specific CWS of concern to the Agency. As discussed in Section III .A.3 , one CWS, Hillsboro CWS (IL1350300) of Illino is, was identified with a 90 - day average concentration in 1994 of simazine plus its two chlorinated degradates exceeding 12.5 ppb. Hillsboro CWS is currently being monitored for atrazine and its three chlorinated degradates as part of the atrazine surfacewater CWS monitoring program. While mitigation measures may be triggered for this CWS through the mechanisms in the monitoring program, and thus may be required in the future, the Agency has determined that no risk mitigation, aside from that being requi red for all simazine products as described above, is neces sary at this CWS at this time. Simazine u sage data available to the Agency indicates that a majority of simazine used in the Midwest is tank mixed with atra zine, and therefore use restrictions (e.g ., setbacks from waterways, restrictions for use in tile - outlettedterraced fields containing standpipes, rate reductions), which have been added to atrazine labels in the years following 1994, have consequently restricted the use of simazine as well. Add itionally, c oncentrations of simazine plus its two chlorinated degradates in this CWS have remained well below the DWLOC of 12.5 ppb level for the past eleven years . Page 51 of 266

### T he Agency has also considered available data from SDWA compliance monitoring, which typi cally consists of samples taken quarterly at a CWS. The Agency has determined that the existence of an annual average concentration in a CWS at or above 2.6 ppb total simazine plus its chlorinated degradates , based on this data, is an appropriate early pr edictor that the 1 2.5 ppb DWLOC could be exceeded. Based on SDWA compliance data from 1997 to 2004, five additional CWS have bee n identified as having concentrations that predict high - end seasonal exposure. These CWS include Johnston County Water System CWS (NC0351070) in North Carolina; Patoka CWS (IL1210400) , Farina CWS (IL0510150) , and Flora CWS (IL0252100) in Illinois ; and Stucker Fork Water Utility CWS (IN5272002) in Indiana. The latter three CWS are currently being monitored for atrazine and its th ree chlorinated degradates as part of the atrazine surface water CWS monitoring program. CWS in the program will be subj ect to an intensive monitoring schedule that will include weekly monitoring for simazine and its two chlorinated degradates in raw wate r at the water intake during the simazine use season and biweekly monitoring for simazine and its two chlorinated degradates in raw water du ring the remainder of the year. Appendix J includes a list of the use season for simazine by state , and subsequentl y the monitoring schedule , for the states in which CWS currently in the monitoring program are located . The regression equation discussed in Section III.A.3 was initially used to identify CWS to put into the simazine surface water monitoring program basedon monitoring data for the parent compound only, and it was used to determine the total concentration of parent compound (atrazine) plus its three chlorinated degradates for CWS in the atrazine surface water monitoring program. However, the Agency unders tands that technology is now availablewhich allows for the collection of measured values for all chlorinated degradates as well as the triazine parent compound s . Thus, t he terms of the simazine surface water monitoring program require that the registrant s directly measure both the parent compound (simazine) plus its two chlorinated degradates for any CWS undergoing the intensive simazine monitoring program. In addition to the six CWS initially in the simazine monitoring program, if the concentration of s imazine plus its two chlorinated degradates reaches 2.6 ppb as an annual average in finished water, or 12.5 ppb as a 90 - day rolling average in raw water at the drinking water intake, based on SDWA data or other reliable monitoring data, for any surface wat er CWS not already in the monitoring program, then the CWS will be subject to the intensive monitoring program involving weekly (during the use season) and biweekly (during the remai nder of the year) monitoring . One exception is that if a CWS has an annua l average concentration of 2.6 ppb or greater based o n only one quarterly sample from SDWA data, and that annual average also does not exceed EPA’s MCL of 4.0 ppb for simazine alone, as established under SDWA, then the technical registrants have the option of either : 1) putting the CWS into the intensive monitoring program the year following the measurement or 2) taking four quarterly samples the year following the measurement to determine if the 2.6 ppb trigger is met or exceededbased on the four samples , and if so, putting the CWS in tothe monitoring program. If a CWS has an annual average concentration of 2.6 ppb or greater based only on one quarterly sample that exceeds 4.0 ppb for simazine alone, the CWS must be put into the intensive monitoring progr am the year following the measurement. Should the CWS to b eadded to the monitoring program be in a stateor states not listed in Appendix J, EPA will determine the corresponding simazine use season in the state(s) to identify the appropriate monitoring s chedule for the CWS . Page 52 of 266

### The technical registrants mu st identify , by April 1 of the subsequent year, any surface water CWS with a concentration of 2.6 ppb or greater simazine plus its two chlorinated degradates based on SDWA compliance data, which includes mea surements of the parent compound only in finished water, and use of the regression equation developed for simazine . The deadline for i dentification of CWS from 2005 SDWA compliance datais May 30, 2006 , rather than April 1, to allow sufficient time for an alysis of 2005 SDWA compliance data after completion of this RED . After five years of consecutive monitoring under the simazine surface water CWS monitoring program , the technical registrants may petition the Agency to remove or modify this requirement to review and report on SDWA data . As part of the simazine surface water CWS monitoring program, t echnical registrants must establish a Simazine Watershed Information Center (SWIC) to provide detailed information on what watershed areas have become subject to a use prohibition for simazine. The circumstances that may lead to a use prohibition through this monitoring program are explained below. T he SWIC must be accessible to the public daily, including weekends and holidays, through a toll - free number avai lable 24 hours a day and seven days a week, a World Wide Web site, and a regular mailing address. Based on changes that will be required on MUP labels (see Table 1 3 below ), a ll simazine products , except those labeled only for use by homeowners on turfgras s or labeled only for use as an algaecide, will be required to bear labels containing the following statement s , as specified in Section V, Table 13 : “ANY USE OF THIS PRODUCT IN AN AREA WHERE USE IS PROHIBITED IS A VIOLATION OF FEDERAL LAW [ this sentence m ust be in all capital letters ]. Before using this product, you must consult the Simazine Watershed Information Center (SWIC) to determine whether the use of this product is prohibited in your watershed. SWIC can be accessed through [ website address ] or [ toll - free phone number] or [ mailing address ]. If the SWIC indicates that use of this product is prohibited in your watershed, you may return this product to your point of purchase or contact [ insert name of Registrant ] for a refund.” This intensive moni toring program will determine the maximum 90 - day average concentration of simazine plus its two chlorinated degradates with sufficient accuracy to allow removal of the 3X FQPA safety factor included in the calculation of the DWLOC to account for exposure - b ased concerns for inadequate monitoring data. As such, the Agency is establishing 37.5 ppb , rather than 12.5 ppb, simazine plus its two chlorinated degradates in raw water at the CWS intake as a 90 - day average as the Agency’s level of concern and performa nce standard that must be met in any CWS that is being intensiv ely monitored in this program. Once CWS are in the intensive monitoring program, mitigation measures, as detailed below, will be required based on this performance standard of 37.5 ppb . Howev er, as described above, CWS will continue to enter into the intensive monitoring program based on SDWA data or other reliable monitoring data when compared to a trigger of 2.6 ppb as an annual average in finished water, or 12.5 ppb as a 90 - day rolling aver age in raw water at the drinking water intake . Under the terms of the monitoring program , the technical registrants are required to submit annual reports to the Agency that include all the results of the year’s analysis by January 30 of the following year . Simazine technical registrants must also notify EPA in writing of any Page 53 of 266

### 90 - day rolling average of 3 7.5 ppb simazine plus its two chlorinated degradates or higher in raw water at the CWS intake within 30 days of the date of the last water sample in that re sult. For any CWS in the monitoring program, monitoring will occur for at least five years and may only cease if no 90 - day rolling average meets or exceeds the performance standard of 37.5 ppb during the five - year period. If this concentration is met or exceeded once in any CWS undergoing intensive monitoring, the technical registrants must su bmit to the EPA, and begin implementing within 90 days of the exceedance, a written mitigation plan including mitigation measures to be implemented within the waters hed area containing the CWS where the exceedance occurred. This mitigation plan will include mitigation measures to be implemented within the watershed area containing the CWS and will include consideration of Best Management Practices such as buffer stri ps, grass waterways, changes in tillage practices, changes in application timing, and use rate reductions. The mitigation plan will also include information on how these measures will be communicated to growers. The technical registrants must submit semi - annual progress reports to EPA describing the mitigation measures taken during that period until notified by EPA that these reports may cease. If this concentration of 37.5 ppb simazine plus its two chlorinated degradates is met or exceededin two separate years in any CWS undergoing intensive monitoring, further use of products containing simazine, except those labeled only for use as an algaecide, will be prohibited in the watershed area containing the CWS . The boundaries of the watershed area will be determined by the Agency after consulting with thetechnical registrants . Products labeled only for algaecides are not included in this use prohibition because, as of 1996, labels confine their use to enclosed ornamental ponds or aquariums of 1,000 gallon s or less and prohibit application or discharge into lakes, flowing water, or ponds with outflow. The SWIC must be updated within 5 business days of receiving EPA’s determination, or changes to this determination, of the boundaries of the watershed area s ubject to the use prohibition so as to describe th is watershed area . In addition, all simazine products labeled only for use by homeowners on turfgrass need to be removed from the shelves of any retailer located within all counties containing any portion of any wate rshed area listed in the SWIC. Corresponding label language is specified in Section V, Table 1 3. I f a CWS is reported to EPA to be in violation of the simazine MCL , the t echnical registrants must consult with the State Drinking Water Admi nistr ator of the state where the CWS is located to develop a written mitigation plan, including mitigation measures to be implemented within the watershed area containing the CWS where the MCL violation occurred, and a schedule for the mitigation plan’s impleme ntation. Technical registrants will submit the written mitigation plan to the EPA within 90 days of the exceedance. If EPA in consultation with the states, determines that the mitigation plan is not reasonably likely to reduce simazine concentrations in the CWS’ water supply, or that the implementation schedule is not met, th e n the use of the products containing simazine , except those labeled only for use as an algaecide, would be prohibited in the watershed area containing the CWS, and the watershed area would be added to the SWIC.

### ii. Re vised Model Concentrations and Additional Confirmatory D ata Need s For those scenarios in which the concentration of simazine wa s modeled, the document “Drinking Water Estimated Concentrations for Simazine and its degradates

–Addendum to Memorandum ‘080807 D307018 DWA revised/ May 27, 2005’ , ” dated January 6, 2006 , provides new estimates of simazine plus its two chlorinated degrad ates in drinking water based on the mitigation measures. Whilet he predictive model PRZM/EXAMS suggest s that the chronic DWLOC or the Agency’s level of concern is exceeded in some cases, the Agency believes that these estimates are upper bound a nd are driven by conservative assumptions used in the model, such as maximum application rates, high spray drift, and high runoff. Additionally, the equation used to calculate the amount of the parent compound (simazine) plus its two chlorinated degradates is conse rvative and likely overestimates the total concentration due to the equation’s derivation from data collected o n degradates which can result from both simazine and atrazine. Further, the dat a used to derive the equation were collected in areas with a hist ory of atrazine useand much higher atrazine concentrations than simazine concentrations . Based on all of this information, EPA believes that actual concentrations of simazine plus its two chlorinated degradates in drinking water will be below the Agency’ s level of concern. F or those crops for which modeled scenarios exceed the chronic DWLOC, the Agency also intends to require representative confirmatory data in the form of a drinking water monitoring study at CWS determined by the Agency to be the most v ulnerable to simazine contamination . The Agency also intends to require as confirmatory data a prospective g round water monitoring s tudy to be completed in F lorida . While modeled concentrations of the parent compound ( simazine ) alone for ground water do not exceed the DWLOC, the Agency needs confirmation that the total concentration of simazine plus its two chlorinated degradates will not meet or exceed the DWLOC of 3 7.5 ppb for infants and children less than 1 year old in ground water in areas of Florida where simazine can be applied at a high rate and where there is high leaching ability due to the sandy soil type, low water table, and high rainfall amount. The lack of sufficient monitoring data on rural wells, and the identification of one sample with a simazine concentration of 11 ppb, substantiate this confir matory data need. While a well - vulnerability study is being completed for atrazine as requir ed in the 2004 DCI for atrazine , this study is targeted for areas of atrazine use, not simazine use, an d does not cover citrus - producing areas in Florida. The Agency intends to place a rural well monitoring study in reserve so these data may be requir ed at a later date if necessary as determined by the results of the prospective ground water monitoring stu dy.

b. Residential Risk Mitigation As discussedin S ection III.A.4, there are potential short - term risks of concern from homeowner exposure to simazine when loading/applying granules via a belly grin der to turfgrass, but post - application risks to toddlers, youths, and adults do not exceed the Agency’s level of concern. To reduce homeowner h andler exposure to simazine, the use of simazine by homeowners using hand - held devices (e.g., belly grinders or handheld rotary applicators) must be restricted to Page 55 of 266

### spot treatment only and a statement must be added to end - use product labels indicating this restriction . EPA has determined that this mitigation measure will reduce risks to homeowner handlers below the A gency’s level of concern. c. Aggregate Risk Mitigation As discussed in Section III.A.5., there are potential aggregate risks of concern from the combination of dietary exposure from drinking water and resi dential exposure for those scenarios where either exposure alone exceeds the Agency’s level of concern. Also there are potential aggregate risks of concerns to toddlers entering treated areas of turfgrass post - application , due to risks of concern for this subpopulation from drinking water exposure alone . Because these risks of concern are all driven by scenarios noted above for which mitigation measures are being required, no additional risk mitigation is necessary to specifically address aggregate risk. The Agency believes that with the required risk mitigation, aggregate risks will be below the A gency’s levels of concern for allsubpopulation s , including infants and children less than 1 year old. d. Occupational Risk Mitigation Asdiscussed in S ection III.A.6 , there are potential shortand intermediate - term risks of concern to occupational handlers for multiple scenarios involving mixing/loading, applying, and mixing/loading/applying products containi ng simazine. To reduce exposure to simazine for occupational handlers and to address subsequent risks of concern, the following mitigation measures are necessary : • prohibit use as “ non - selective weed control on non - crop land ” on product label s ; • prohibit fo rmulation of simazine into wettable powder formulations ; • prohibit formulation of simazine into granular fo rmulations for occupational use, which includes uses covered under the WPS a nd non - WPS commercial uses ; • prohibit aerial application and add a statemen t to product label s indicating this prohibition ; and • reduce appl ication rate on corn to a maximum of 2 pounds active ingredient per acre ( lbs ai/A ) per application and a maximum of 2.5 lbs ai/A per year . Additional rate reductions to typical rates (as spe cifiedin Section V , Table 13 ) and harmonization of application rates on simazine product labels will further reduceoccupational handler exposure to simazine for various scenarios. In order to eliminate the need to use engineering controls with dry flowa bles formulations to reduce occupational handler risks below the Agency’s level of concern , the registrants agreed to reduce the application rate on grapes to a maximum of 4 lbs ai/A per application and per calendar year. As discussed in the document “Rev iew of Simazine Dry Flowable Exposure Scenario for Applications to Corn, Grapes, and Florida Oranges, D307039 , ” dated January 30 , 2006, t he Agency has also determined that intermediate - term exposure will not occur when occupational handlers are mixing/load ing dry flowable and liquid formulations fo r chemigation application, so PPE or eng ineering controls to address the s escenario s are unnecessary. Page 56 of 266

### The re calculated MOEs , based on the mitigation measures and additional reduced rates , are available inthe docu ment “Simazine : Addendum to HED Risk Assessment (11/30/05, D320052) Chapter of the Reregistration Eligibility Decision (RED) . DP Barcode: 325685 , ” dated January 31, 2006. For many of simazine’s use scenarios, the PPE necessary to reduce occupational handl er risks below the Agency’s level of concern is chemical - resistant gloves (as specified in Section V, Table 13 ). In addition to gloves , m ixer/l oaders of dry flowable formulations supporting groundboom applications need to wear coveralls over their long - sl eeve shirts and pants, chemical - resistant footwear, and PF 5 NIOSH- approvedrespirators with a dust/mist filter in order to reduce exposure risks below the Agency’s level of concern . In other words, with this PPE no MOEs exceed the Agency’s level of conce rn. The Worker Protection Standard for Agricultural Pesticides requires a restricted - entry interval (REI) of at least 12 hours for all usesand this REI must appear on all product labels . There are two use s for which potential risks of concern exist aft er 12 hours for re - entry workers

– Christmas trees and turfgrass on sod farms when applied at a rate of 4 lbs ai/A. To reduce post - application exposure and to address subsequent risks of concern the following mitigation measures are necessary : • specify a n REI for Christmas trees of 48 hours on product la bels ; and • require watering- in of products that can be used on tur fgrass on sod farms when the rate is greater than 2 lbs ai/Athrough a statement on products labels . 2. EcologicalRisk Management and Mitiga tion As discu ssed in Sections III.B.2, and 3 , there are potential acute risks of concern, or direct adverse acute effects, to non - target aquatic and terrestrial organisms i n the following taxonomic groups from exposureto the parent compound ( simazine ) only: vascular aquatic plants, non - vascular aquatic plants, monocot terrestrial plants, and dicot terrestrial plants. The Agency also estimates that although avian mortality is unlikely fro m acute simazine exposure there is a potential for acute sublethal effects to birds (e.g., reduced reaction to external stimuli, wing drop, depression) . The Agency estimates that there are potential chronic risks of concern, or direc t adverse chronic effe cts, to non - target terrestrial organisms in the following taxonomic groups: birds and mammals. Potential chronic effects for both freshwater and marine/estuarine fish and invertebrates are unknown for the technical grade active ingredient although availab le data on a formulation of 80% active ingredient indicate that the use of simazine is unlikely to result in chronic risk to fish and invertebrates. To reduce aquatic and terrestrial organism exposure to simazine and to address subsequent risks of concern , the following mitigation measures are necessary : • prohibit use as “ non - selective weed control on non - crop land ” on product labels ; • prohibit formulation of simazine into granular formulations for agricultural use; and • reduce maximum application rates to ty pical rates (as specified in Section V, Table 13), further restrict use on corn in areas with highly erodible soils (similar Page 57 of 266

### to rate reductions for use of atrazine on corn), and harmonize application rates on simazine product labels. Chronic RQs for thes e organisms were recalculated based on the mitigation measures in the document “Revised Simazine RQs for Terrestrial Animals and Plants Based on Proposed Harmonized Labels , ” dated December 8, 2005. While the Agency’s acute and chronic level of concern is still exceeded for some taxonomic groups , most notably for birds and mammals , t he Agency believes that these estimates areconservative since they consider 100% of the organism’s diet is from areas treated with simazine . Additionally, the prohibition of a erial application of simazine, a risk mitigation measure necessary to reduce drinking water and occupational exposure and subsequent risks of concern, plus the addition of pesticide - specific label language describing the environmental hazards of simazine u se and restricting spray drift (as further detailed in Section V, Table 1 3) , will have an overall effect of reducing aquatic and terrestrial organism exposure to simazine. T he Agency intends to require confirmatory acute toxicity data on freshwater fis h and invertebrates; confirmatory chronic toxicity data on freshwater and estuarine/marine fish and invertebrates; confirmatory acute oral toxicity data on birds for sublethal effects; and confirmatory eco toxicity data on simazine’s two chlorinated degrada tes for all taxonomic groups ex cept mammals, birds, and plants. The Agency will also take into consideration the results of laboratory and field studies now underway on atrazine’s potential sublethal effects to amphibians, specifically impacts on gonadal development in frogs, and intends to place in reserve a similar study for simazinein the DCI so that these data may be required at a later date if necessary. 3 . Other Labeling Requirements In order to be eligible for reregistration, simazine use and user safety information also needs to beincluded in the labeling of all end - use products containing simazine . For the specific label statements and a list of additional data requirements necessary to co nfirm this decision , refer to Section V of this RED document. 4 . Threatened and Endangered Species Considerations For Listed Species , the Agency’s level of concern for direct effe cts w as exceeded for the following taxonomic groups: freshwater fish, freshwater invertebrates, vascular aquatic plants, birds, mammals, monocot terrestrial plants, and dicot terrestrial plants. There also may be the potential for indirect adverse effects for some Listed Species that are dependent on these taxonomic groups . The Agency has developed the Endangered Species Protection Program to identify pesticides whose use may cause adverse impacts on th reatened and endangered species and to implement mit igation measures that address these impacts. The Endangered Species Act requires federal agencies to ensure that their actions are not likely to jeopardize Listed Species or adversely modify designated critical habitat. To analyze the potential of regist ered pesticide uses that may affect any particular species, EPA uses basic toxicity and exposure data developed for Page 58 of 266

### REDs and then considers ecological parameters, pesticide use information, geographic relationship between specific pesticide uses and specie s locations, and biological requirements and behavioral aspects of the particular species. When conducted, this species- specific analysis will take into consideration any risk mitigation measures that are being implemented as a result of this RED. Follo wing this future species - specific analysis, a determination that there is a likelihood of potential effects to a Listed Species may result in limitations on use of simazine , other measures to mitigate any potential effects, or consultations with the Fish a nd Wildlife Service and/or the National Marine Fisheries as appropriate. If the Agency determines use of simazine “ may effect” Listed Species or their designated critical habitat, EPA will employ the provisions in the Services regulations (50 CFR Part 402 ). Until a species - specific analysis is completed, the risk mitigation measures being implemented through this RED will reduce the likelihood that endangered and threatened species may be exposed to simazine at levels of concern. EPA is not requiring spe cific simazine label language at the present time relative to threatened and endangered species. If, in the future, specific measures are necessary for the protection of Listed Species , the Agency will implement them through the Endangered Species Program . V. What Registrants Need to Do The Agency has determined that simazine is eligible for reregistration provided that the risk mitigation measures outlined in this document are adopted and label ame ndments aremade to reflect these measures. The Agency intends to issue DCIs for generic ( technical grade ) data and product - specific data. Generally, registrants will have 90 days from receipt of a generic DCI to complete and submit response forms or req uest time extension and/or waiver requests with a full written justification. Table 12 below presents the additional generic data the Agency intends to require for simazine to confirm the decision that simazine is eligible for reregistration. For product - specific DCIs, registrants will have eight months to submit d ata and amend labels. In order for simazine to be eligible for reregistration, all p roduct labels must be amended to incorporate the specific changes and language presented in Table 13 below . Table 13 also describes how the required language should be incorporated. A. Manufacturing - Use Products 1. Additional Generic Data Requirements The generic database supporting the reregistration of simazine has been reviewed and determined to be substantially complete. However, EPA is requiring the following additional data to confirm the decisions presented in this RED. T he Agency intends to issue a generic DCI for this data .

### 2. Labeling for Manufacturing - Use Products To ensure compliance with FIF RA, labeling for all MUPs should be revised to comply w ith all current EPA regulations, PR Notices , and applicable policies. The M U P labeling should bear the specific language presented in Table 13 below. B. End- Use P roducts 1. Additional Product - Specific Data Requ irements Section 4(g)( 2 )(B) of FIFRA calls for the Agency to obtain any needed product - specific data regar ding the pesticideafter a determination of eligibility has been made. The reg istrant must review previous data submissions to ensure they meet current EPA acceptance criteria and if not, commit to conduct new studies. If a registrant believes that previously submitted data meet current testing standards, then the study MRID number s can be cited according to the instructions in the Requirement Status and Registrations Response Form provided for each product. The Agency intends to issue a separate product - specific DCI outlining specific data requirements . 2. Labeling for End - Use Products To be eligible for reregistration, l abeling changes are necessary to implement measures outlined in Section IV above. The specific changes and language are presented in Table 13 below. Gener ally, conditions for the distribution and sale of products bearing old labels/labeling will be established when the label changes are approved. However, specific existing stocks time frames will be established case - by- case, depending on the number of prod ucts involved, the number of label changes, and other factors.

### Appendix D. Citations Considered to be Part of t he Database Supporting the Reregistration Decision (Bibliography) Guide to Appendix D 1. Contents of Bibliography . This bi bliography contains citations of all studies considered relevant by EPA in arriving at the positions and conclusions stated elsewhere in the Reregistration Eligibility Document. Primary sources for studies in this bibliography have been the body of data s ubmitted to EPA and its predecessor agencies in support of past regulatory decisions. Selections from other sources including the published literature, in those instances where they have been considered, are included. 2. Units of Entry . The unit of entry i n this bibliography is called a "study." In the case of published materials, this corresponds closely to an article. In the case of unpublished materials submitted to the Agency, the Agency has sought to identify documents at a level parallel to the publ ished article from within the typically larger volumes in which they were submitted. The resulting "studies" generally have a distinct title (or at least a single subject), can stand alone for purposes of review and can be described with a conventional bi bliographic citation. The Agency has also attempted to unite basic documents and commentaries upon them, treating them as a single study. 3. Identification of Entry . The entries in this bibliography are sorted numerically by Master Record Identifier, or "M RID” number. This number is unique to the citation, and should be used whenever a specific reference is required. It is not related to the six - digit "Accession Number" which has been used to identify volumes of submitted studies (see paragraph 4(d)(4) be low for further explanation). In a few cases, entries added to the bibliography late in the review may be preceded by a nine character temporary identifier. These entries are listed after all MRID entries. This temporary identifying number is also to beused whenever specific reference is needed. 4. Form of Entry . In addition to the Master Record Identifier (MRID), each entry consists of a citation containing standard elements followed, in the case of material submitted to EPA, by a description of the ear liest known submission. Bibliographic conventions used reflect the standard of the American National Standards Institute (ANSI), expanded to provide for certain special needs. a. Author. Whenever the author could confidently be identified, the Agency has c hosen to show a personal author. When no individual was identified, the Agency has shown an identifiable laboratory or testing facility as the author. When no author or laboratory could be identified, the Agency has shown the first submitter as the autho r. b. Document date. The date of the study is taken directly from the document. When the date is followed by a question mark, the bibliographer has deduced the date from the evidence contained in the Page 93 of 266

### document. When the date appears as (1999), the Agency w as unable to determine or estimate the date of the document. c. Title. In some cases, it has been necessary for the Agency bibliographers to create or enhance a document title. Any such editorial insertions are contained between square brackets. d. Trailing p arentheses. For studies submitted to the Agency in the past, the trailing parentheses include (in addition to any self - explanatory text) the following elements describing the earliest known submission: (1) Submission date. The date of the earliest known subm ission appears immediately following the word "received." (2) Administrative number. The next element immediately following the word "under" is the registration number, experimental use permit number, petition number, or other administrative number associate d with the earliest known submission. (3) Submitter. The third element is the submitter. When authorship is defaulted to the submitter, this element is omitted. (4) Volume Identification (Accession Numbers). The final element in the trailing parentheses identi fies the EPA accession number of the volume in which the original submission of the study appears. The six- digit accession number follows the symbol "CDL," which stands for "Company Data Library." This accession number is in turn followed by an alphabeti c suffix which shows the relative position of the study within the volume.

### Appendix G. EPA’s Batching of Simazine Products for Meeting Acute Data Requirements for Reregistration In an effort to reduce the time, resources and number of animals needed to fulfill the acute toxicity data requirements for reregistration of products containing SIMAZINE as the active ingredient , the Agency has batched products which can be considered similar for purposes of acute toxicity. Factors considered in the sorting process include each product's active and inert ingredients (identity, percent composition and biological activity), type of formulation (e.g., emulsifiable concentrate, aerosol, wettable powder, granular, etc.), and labeling (e.g., signal word, use classification, precautionary labeling, etc.). Note that the Agency is not describing batched products as "substantially similar" since some products within a batch may not be considered chemically similar or have identical use patterns. Using available information, batching has been accomplished by the process described in t he preceding paragraph. Notwith standing the batching proc ess, the Agency reserves the right to require, at any time, acute toxicity data for an individual product should the need arise. Registrants of products within a batch may choose to cooperatively generate, submit or cite a single battery of six acute tox icological studies to represent all the products within that batch. It is the registrants' option to participate in the process with all other registrants, only some of the other registrants, or only their own products within a batch, or to generate all th e required acute toxicological studies for each of their own products. If a registrant chooses to generate the data for a batch, he/she must use one of the products within the batch as the test material. If a registrant chooses to rely upon previously su bmitted acute toxicity data, he/she may do so provided that the data base is complete and valid by today's standards (see acceptance criteria attached), the formulation tested is considered by EPA to be similar for acute toxicity, and the formulation has n ot been significantly altered since submission and acceptance of the acute toxicity data. Regardless of whether new data is generated or existing data is referenced, registrants must clearly identify the test material by EPA Registration Number. If more th an one confidential statement of formula (CSF) exists for a product, the registrant must indicate the formulation actually tested by identifying the corresponding CSF. In deciding how to meet the product specific data requirements, registrants must follow the directions given in the Data Call - In Notice and its attachments appended to the RED. The DCI Notice contains two response forms which are to be completed and submitted to the Agency within 90 days of receipt. The first form, "Data Call - In Response," asks whether the registrant will meet the data requirements for each product. The second form, "Requirements Status and Registrant's Response," lists the product specific data required for each product, including the standard six acute toxicity tests. A registrant who wishes to participate in a batch must decide whether he/she will provide the data or depend on someone else to do so. If a registrant supplies the data to support a batch of products, he/she must select one of the following options: Develop ing Data (Option 1), Submitting an Existing Study (Option 4), Upgrading an Existing Study (Option 5) or Citing an Existing Study (Option 6). If a registrant depends on another's data, he/she must choose among: Cost Sharing (Option 2), Offers to Cost Share (Option 3) or Citing an Page 251 of 266

### Existing Study (Option 6). If a registrant does not want to participate in a batch, the choices are Options 1, 4, 5 or 6. owever, a registrant should know that choosing not to participate in a batch does not preclude other registrants in the batch from citing his/her studies and offering to cost share (Option 3) those studies. Thirty - three products were found which contain Simazine as the active ingredient. These products have been placed eight batches and a no batch group in acco rdance with the active and inert ingredients and type of formulation. Batching Instructions : Batch 5: EPA Reg. No. 7689 - 17 may not cite data generated with EPA Reg. No. 7689 - 16. No Batch: Each product in this Batch should generate their own data. NO TE: The technical acute toxicity values included in this document are for informational purposes only. The data supporting these values may or may not meet the current acceptance criteria.

### Appendix J. Letter to Amend Terms and Conditions of MUP Registrations I hereby request that the registration for [ insert registration numbers for all manufacturing use products; can be listed in an attachment] beamended to include the following terms and conditions of continued registration. Drinking water mitigation: 1) SWIC: [ Registrant] shall establish a database of information (referred to hereafter as Simazine Watershed Information Center or SWIC). The SWIC will provide detailed information on what watershed areas have become subject to a prohibition of Simazine use pursuant to paragraph 3)f) below. Only information approved by EPA will be i ncluded in the SWIC. The SWIC will be accessible to the public daily, including weekends and holidays, through a toll - free telephone number available 24 hours a day and seven days a week, a World Wide Web site, and a regular mailing address. Information for each means of contact will be included on all Simazine product labels pursuant to paragraph 2) below. The SWIC will be updated a) within 5 business days of receiving EPA's determination of the boundary of any watershed area in which use of Simazine is prohibited due to results of monitoring under paragraph 3) below; and b) within 5 business days of receipt of notification from EPA of a change to the description of any watershed area affected by a use prohibition. This condition of registration may also be satisfied by offering to pay compensation to another registrant that performs the acts required . 2) Label changes: the following label changes will be submitted tothe Director of EPA’s Registration Division (7505C), Office of Pesticide Programs , ATTN : Jim Tompkins, PM Team 25, for approval no later than June 1, 2006. a) The label shall include under "Directions for Use" the following statements: i) "This product may not be reformulated or repackaged into another product unless the registration of the re formulated or repackaged product was granted or amended so as to be consistent with the Surface Water CWS Monitoring Program set forth in the Simazine Reregistration Eligibility D ecision (RED)." ii) "No product other than a product labeled only for use by hom eowners on turf grass or labeled only for use as an algaecide may be reformulated or repackaged from this product unless the formulated or repackaged product bears a label including all of the following statements prominently displayed in the "Directions fo r Use" section: "ANY USE OF THIS PRODUCT IN AN AREA WHERE USE IS PROHIBITED IS A VIOLATION OF FEDERAL LAW [this sentence must be in all capital letters]. Before using this product, you must consult the Simazine Watershed Information Center (SWIC) to determine whether the use of this product is prohibited in your watershed. SWIC can be accessed through [website address] or [toll - free phone number] or [mailing address]. If the SWIC indicates that use of this product is Page 261 of 266

### prohibited in your watershed, you ma y return this product to your point of purchase or contact [ insert name of Registrant ] for a refund." iii) "No products labeled only for use by homeowners on turf grass may be reformulated or repackaged from this product unless the registration of the resulting product is subject to the following terms and conditions of registration, which shall require that the Registrant: (1) Immediately cease all sale and distribution to any retailer or any entity distributing or selling such product to any retailer located with in all counties containing any portion of any watershed area listed in the SWIC; (2) Ensure the removal of any such Simazine product from the shelves of any retailer located within all counties containing any portion of any watershed area listed in the SWIC; a nd (3) Repurchase any such Simazine product from any of the purchasers described above. (4) In addition, such Registrant shall consult with the State(s) in which such counties are located to determine whether additional territory shall be included in the area t o which these requirements will apply. If the State(s) determine that a larger area is warranted, the Registrant shall within 10 days of such determination notify the Director of EPA's Special Review and Reregistration Division (SRRD) (7508C), Office of P esticide Programs, of the State(s) determination. EPA will then notify such Registrant of the specific boundaries within which the stop sale, removal and repurchase shall take place." b) All manufacturing use product sold or distributed after July 31, 2006 will bear this revised label. 3) Surface water monitoring program: [Registrant] will conduct the following water monitoring program as a term and condition of continued registration of the product. This condition of registration may also be satisfied by o ffering to pay compensation to another registrant that performs the acts required. a) Review of Safe Drinking Water Act (SDWA) data: Beginning with 2005 data, each year, [Registrant] will review all SDWA data for every Community Water System (CWS) that has a surface water source and tests for Simazine . If any such CWS has an annual average concentration of S imazine and its two chlo rinated degradates equal to or greater than 2.6 ppb in finished water , that system will be placed into the intensive m onitoring program in paragraph 3)c) below. (Except, that if a CWS has an annual average based on a sing le sample equal to or greater than 2.6 ppb S imazine and its two chlorinated degradates but less than 4.0 ppb Simazine (parent compound only), then [Registrant] h as the option of either placing the CWS in the intensive monitoring program the year following these measurements or taking quarterly samples at that CWS during the year following these measurements and averaging the quarterly samples. If the average of t he Page 262 of 266

### quarterly samples is greater than 2.6 ppb Simazine and its two chlorinated degradates, then the CWS must be placed in the intensive monitoring program the following year.) [Registrant] will submit a report of this review for the 2005 data by May 30, 2006. For each subsequent year, [Registrant] will submit a report by April 1 of the following year , beginning April 1, 2007. i) For any CWS where concentrations of only the Simazine parent compound have been measured (i.e. no degradates), the total concentration of Simazine and its two chlorinated degradates wi ll be calculated using the following regression formula: Σ (Simazine + G28273 + G28279) = 0.364 + 1.378 * (Simazine) G-28273 = (diaminochlorotriazine or DACT) G-28279 = (des-isopropyl atrazine or DIA) ii) After 5 years of consecutive monitoring under paragraph 3)c) [Registrant] may request that EPA remove or modify this requirement to review and report on SDWA data. b) Systems to be monitored: The following CWS will be intensively monitored for Simazine and its two chlorinated degradates: i) IL1350300 Hillsboro CWS, Illinois IL1210400 Patoka CWS, Illinois IL0510150 Farina CWS, Illinois IL0252100 Flora CWS, Illinois NC0351070 Johnston County Water System CWS, North Carolina IN5272002 Stucker Ford Water Utility CWS, Indiana; ii) Any CWS identified through annual revi ew of SDWA data pursuant to paragraph 3)a) noted above; and iii) Any other CWS that has a surface wate r source and for which any reliable data indicates an annual concentratio n of 2.6 ppb or more Simazine and its two chlorinated degradates in finished water or a concentr ation of 12.5 ppb or more Simazine and its two chlorinated degradates as a 90-day average in raw water. c) Intensive monitoring: Beginning no later than April 30, 2006, each CWS identified in paragraph 3)b)i) will be monitored for actual concentrations of Simazine and each of its two chlorinated degradates in raw water at the water intake weekly during peak use seasons base d on Simazine usage in the area (listed in Attachment 1) and bi-weekly during the rest of the year. Each CWS identified through paragraphs 3)b)ii) and 3)b)iii) will be monitored for actual concentrations of Simazine and each of its two chlorinate d degradates in raw water at the water intake weekly during peak use seasons ba sed on Simazine usage in the area as Page 263 of 266

### determined by EPA upon identification of the CWS, and bi - weekly during the rest of the year. [Registrant] will calculate 90 - day rolling average concentrations of the total of Simazine and its two chlorinated degradates. Monitoring at any specific CWS may cease when five consecutive years have passedwithout any 90 - day rollin g average concentration of Simazine and its two chlorinated degradates meeting or exceeding 37.5 ppb. d) Reporting: The results of monitoring will be reported to EPA annually by January 30 of the following year. In addition, if any CWS has a 90 - day rolling average total concentration of Simazine and its two chlorinated degradates greater than 37.5 ppb, this will be reported to EPA within 30 days from the last water sample included in that result. e) Mitigation plans: i) If any CWS has a 90 - day rolling average total concentration of Simazine and its two chlorinated degradates at or above 37.5 ppb, then [Registrant] will submit to EPA and begin implementing within 90 days of that exceedance a written Mitigation Plan including mitigation measures to be implemente d within the watershed area containing that CWS (except as provided in paragraph 3)g) below). Such plan shall include consideration of Best Management Practices such as buffer strips, grass waterways, changes in tillage practices, changes in application t iming, and use rate reductions, and how the measures will be communicated to growers. [Registrant] will implement this Mitigation Plan and submit progress reports to EPA semiannually describing the measures taken during that period, until notified by EPA that semi - annual reports may cease. ii) If any CWS is reported to EPA to be in violation of the maximum contaminant level (MCL) for Simazine (as determined by reporting under the Safe Drinking Water Act), then [Registrant] will consult with the State Drinkin g Water Administrator of the State where such CWS is located to develop a written Mitigation Plan including mitigation measures to be implemented within the watershed area containing that CWS and a schedule for implementation. Such plan shall include cons ideration of Best Management Practices such as buffer strips, grass waterways, changes in tillage practices, changes in application timing, and use rate reductions, and how the measures will be communicated to growers. [Registrant] will submit the plan toEPA within 90 days of the reported violation and will implement this Mitigation Plan and submit progress reports to EPA semi - annually describing the measures taken during that period, until notified by EPA that semi - annual reports may cease. However, if EPA, in consultation with the State, determines that the Mitigation Plan is not reasonably likely to reduce Simazine concentrations in the CWS’s water supply, or that the implementation schedule is not met, then use of products containing Simazine Page 264 of 266

### would b e prohibited and the watershed area where the CWS is located would be included in the SWIC pursuant to paragraph 3)f) below. f) Prohibition of use through the SWIC: If any CWS has a 90 - day rolling average total concentration of Simazine and its two chlorina ted degradates at or above 37.5 ppb in two separate years within a five year period, then use of Simazine will be prohibited in the watershed area containing that CWS (except as provided in paragraph 3)g) below and for products labeled only for use as an a lgaecide). The boundaries of the watershed area will be determined by EPA, after consulting with Registrants of Simazine. The watershed area will be listed in the SWIC, through which users can determine whether use is allowed where they intend to use the product. g) Force Majeure: In the event that [Registrant] can demonstrate that any CWS’s 90 - day rolling average total concentration of Simazine and its two chlorinated degradates meets or exceeds 37.5 ppb due solely to acts of sabotage, non - farm point sour ce incidents such as rail or truck spills, or acts of God (excluding runoff from rainfall), that reading will not count toward either prohibition of use of Simazine under paragraph 3)f) above or submission of a Mitigation Plan under paragraph 3)e) above. 4) [Registrant] agrees that failure to comply with any of the terms and conditions in this amendment will be grounds for cancellation under FIFRA § 6(b), and that the only issue for resolution would be whether or not [Registrant] complied with the terms and c onditions. I certify that I am authorized to request this registration amendment on behalf of [Registrant]. Any further communications concerning this registration should be directed to [contact info].
