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. Simazine has also been determined to share a 

neuroendocrine mechanism of toxicity with two other structurally-related chlorinated triazines, 

atrazine and propazine, and their three chlorinated degradates. The 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 atrazine the cumulative risks 

associated with these pesticides are below 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 identifiable subgroups of consumers, from the use of 

simazine, atrazine, and propazine. The Agency has determined that simazine will be eligible for 

reregistration provided that the risk mitigation measures outlined 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 simazine 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 specific uses, formulations, and 

application methods; reducing maximum application rates to typical rates; establishing a 

performance standard for raw water concentrations; requiring appropriate 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 provided 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 Eligibility Decisions (REDs). 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 Agency). 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 determine 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 into law. This 

Act amended 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 those chemicals 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 pesticide'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 for 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 atrazine, simazine, 

and propazine, and their three chlorinated degradates, as sharing a common neuroendocrine 

mechanism of toxicity. The Agency has completed its cumulative risk assessment for the 

chlorinated triazine class of pesticides and has concluded that with the mitigation measures in 

this document and in the 2003 Interim Reregistration Eligibility Decision (IRED) 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 
HQ-OPP-2005-0481 located on-line in the Federal Docket Management System (FDMS), 

http://www.regulations.gov. 

This document presents EPA's revised human health and environmental fate and effects 

risk assessments, its progress toward tolerance reassessment, and the reregistration eligibility 

decision for simazine. The document consists of six sections. Section I contains the regulatory 

framework for reregistration and tolerance reassessment. Section II provides a description of the 

chemical and a profile of the use and usage of the chemical. Section III provides a summary of 

the human health and ecological risk assessments which have been revised based on data, public 

comments, and other information received in response to the preliminary risk assessments. 

Section IV presents the Agency's risk management, reregistration eligibility, and tolerance 

reassessment decisions. Section V summarizes the data requirements necessary to confirm the 

reregistration eligibility decision as well as label changes and language necessary to implement 

the risk mitigation measures outlined in Section IV. Section VI, the Appendices, provides 

related information and supporting documents. The preliminary and revised risk assessments for 

simazine are available in the public docket EPA-HQ-OPP-2005-0151 located on-line in FDMS,

Simazine is a chlorinated triazine herbicide, a class of herbicides that also includes the 

pesticides atrazine and propazine. The Registration 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 

for simazine in September 1991. Subsequent DCIs were issued in August 1992, March 1995 and 

October 1995. This RED reflects an assessment of all data submitted to date. 

In 1994 EPA’s Office of Water (OW) established a Maximum Contaminant Level (MCL) 

for simazine in finished 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 cons 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 for human health risks of 

concern resulting from drinking water exposure caused from ground and surface water 

contamination. At the time that the Special Review was initiated, atrazine and the other triazines 

were classified as Group C carcinogens, or possible human carcinogens. Cyanazine registrations 

were cancelled effective December 1999 and atrazine and simazine were later reclassified as 

“not likely to be carcinogenic to humans.” The 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 currently 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 uses of simazine. Sections IV 

and V include information on those currently 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. 

Page 11 of 266 
Methods of Application: End-use products 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 products can also be applied 

by aerial broadcast. 

Use Sites: Simazine is registered 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 crops, 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 tank 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 algaecide in ornamental ponds and aquariums of 1,000 

gallons or less. 

Application Rates: For agricultural uses, the 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 lbs ai/ A. 

Estimated Usage: 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, 

nearly 2 million pounds of simazine are applied each year in the 

Midwest (more than 90% on corn); more than 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 citrus (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 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 

(simazine ) only. In addition to bananas and fish, tolerances for simazine currently 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 
byproducts, and meat), cherry, corn (forage, sweet, grain, and stover), cranberry, currant, 

dewberry, egg, filbert (i.e., hazelnut), goat (fat, meat byproducts, and meat), grapefruit, grape, 

grass, grass (forage and hay), hog (fat, meat byproducts, and meat), horse (fat, meat byproducts, 

and meat), lemon, loganberry, milk, macadamia nut, olive, orange, peach, pear, pecan, plum, 

poultry (fat, meat byproducts, and meat), raspberry, sheep (fat, meat byproducts, and meat), 

strawberry, sugarcane (molasses), and walnut. 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 Assessments 

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 to determine the toxicity category 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 IV 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.

In a sub-chronic developmental toxicity study, incomplete or absent bone formation or 

ossification was observed in fetal rats following exposure of pregnant rats to simazine. These 

developmental effects are presumed to occur after a single exposure and are therefore 

appropriate for consideration in the acute exposure scenario for dietary risk from food and 

drinking water. 

Page 13 of 266 
After subchronic and chronic exposure to simazine, a variety of species were shown to 

exhibit neuroendocrine effects resulting in both reproductive and developmental consequences 

that are cons idered relevant to humans. These effects are biomarkers of a neuroendocrine 

mechanism of toxicity that is shared by several other structurally-related chlorinated triazines 

including atrazine, propazine, and three chlorinated degradates – G-28279 (des-isopropyl 

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. These 

neuroendocrine effects are considered the primary toxicological effects of regulatory concern for 

all subchronic and chronic 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 common 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 atrazine, hydroxy-atrazine. On the basis of the results of a risk 

assessment for hydroxy-atrazine that 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 mammary 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 reclassified in 2000 as “not likely to be carcinogenic to 

humans.” Simazine 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 epidemiology 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-Hodgkin’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. Gabriel, Louisiana. These 

studies are currently undergoing review. At this time there are two other studies pending in the 

near future from 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 NCI of enough cases of this relatively rare cancer. 

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 meeting, EPA intends to present the SAP 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 any of these submissions raise significant 

questions that would benefit substantially from SAP review prior to submission of all of the data, 

the Agency will hold a SAP meeting before all aspects of NCI’s Agricultural Health Study are 

completed. EPA intends to thoroughly review any SAP report from any future meeting, once 

issued, and to review its determinations regarding the carcinogenic potential of atrazine, and 

simazine, as necessary. EPA will also continue to 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 critical health effects observed in 

toxicity studies on animals) and corresponding doses or concentrations, were derived for 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 or chronic (more than 6 months). 

All endpoints, aside from the acute endpoint used for females ages 13 to 49 derived from a 

toxicity study on animals exposed to simazine, were derived from toxicity studies on animals 

exposed to atrazine 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, the Agency concluded that atrazine data could be used as bridging data for simazine due 

to the fact that simazine 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 are considered to be 

applicable to the general U.S. population, including infants and children.

2. Dietary Exposure and Risk from 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 expected, is not of concern to the Agency. Chronic dietary 

risk from food is calculated using the average food consumption values for each population subgroup 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 and 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 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 factor 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. 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. 

The 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 observable (“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 an 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 variability (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 simazine 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 from food is estimated to be essentially zero, resulting 

in a risk estimate 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/kg/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 subgroups 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 Exposure 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 dietary 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 pesticide in drinking water after dietary exposure from food is considered. Acute 

and chronic risks from drinking water are assessed by determining if the DWLOC is exceeded by 

monitored or modeled concentrations in both surface and ground water. Concentrations that 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 surface and ground water. Potential residues of concern in drinking water are simazine 

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 inadequate monitoring 

data was removed because the models are protective and provide upper-bound concentrations. 

Page 19 of 266 
DWLOCs for comparison against concentrations as monitored 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 on monitoring data: 

o Infants and children less than 1 year old = 12.5 ppb 

o Children ages 1 to 6 = 23 ppb 

o Children ages 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 = 37.5 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 estimate 

concentrations and focused on five regions 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 identify 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 initially 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 more frequent measurements for 

concentrations of simazine and its two chlorinated 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 (simazine) plus its two chlorinated degradates and levels of the parent compound 

alone. The regression equation is �(simazine + DACT + DIA) = 0.364 + 1.378 * (simazine). 

This analysis allowed EPA to derive conservative estimates of concentrations for total simazine 

plus its two chlorinated degradates when these data were not available in the databases. 

Page 20 of 266 
Estimated maximum peak, 90-day average, and annual average concentrations of 

simazine in surface water for California and Florida were generated using the predictive model 

Pesticide Root Zone Mode/Exposure Analysis Modeling System (PRZM/EXAMS) because 

sufficient monitoring data were not available for areas where simazine use is most intensive in 

these states. PLEX contains infrequent and sparse measurements from 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 sources 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 modeled scenarios include the following and are listed in Table 3: almonds in 

California with a banded application 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 Hawaii and California; fruit in California with a banded 

application rate to represent use at this application rate on fruit trees (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 trees grown nationwide; citrus 

in California with a broadcast application rate; and citrus in Florida with a broadcast application 

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 estimated 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 Agency 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 considered 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 these concentrations were not evident in PLEX or VMP/AMP. 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. 

No surface or 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 

monitoring 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 identifies 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 CWS 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 old. 

Modeled 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 ingredient per acre (lbs 

ai/A); fruit trees (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 37.5 ppb for 

infants and children less than 1 year old and/or 69 ppb for children ages 1 to 6. 

Modeled surface water concentrations 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 trees 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 do 

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 additional 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, highway 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 preputial 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. The MOE level of concern includes an 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 ). The 

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 factor 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 account for exposure-based uncertainty because the 

assessment is based on EPA’s Standard Operating 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 below 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 handler 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 assumed for each 

scenario assessed. 

Page 24 of 266 
Of the four homeowner handler scenarios assessed, one results in a risk that exceeds 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 an MOE of 76 for short-term derma l 

exposure. When dermal exposure and inhalation exposure are combined for this scenario, the 

MOE that results is 75. For the post-application scenarios assessed for toddlers, youths, and 

adults, no risks exceed the Agency’s level of concern (i.e., all MOEs are greater than or equal to 

300). 

5. Aggregate Exposure and Risk 

In accordance with FQPA, the Agency considers and aggregates pesticide exposures and 

risks for dietary exposure (from both food and drinking water) as well as residential exposure if 

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 exposure are based on acute dietary exposure from 

drinking water only. As discussed above, no surface or 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 exposure from the dermal 

and inhalation routes of exposure as well as chronic drinking water exposure. Risk estimates for 

adults, youths, 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 chronic drinking water exposure. 

EPA did not aggregate 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 risk estimates 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 aggregate 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-term 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 

exposure only; however, modeled concentrations 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 exposure for these 

exposure durations. Risk estimates are of concern to infants, toddlers, and the general U.S. 

population for those scenarios previously noted. 

6. Occupational Exposure and Risk 

As with residential exposure, occupational risk is expressed as an MOE. For simazine, a 

neuroendocrine endpoint was identified 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 

effects of estrous cycle alterations and LH surge suppression observed in an 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 determined for 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 among 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 100%, respectively, as well as maximum application 

rates and the number of acres that can be reasonably treated in a day, were assumed for each 

scenario assessed. Based on a common endpoint of toxicity, dermal and inhalation exposure 

were combined in the calculation 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. The MOEs 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 baseline exposure. Baseline assumes 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) are 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 assessed at various levels of risk mitigation:

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, short-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. The maximum MOEs 

attainable for each scenario are bolded.

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 with 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 the skin of an individual in contact with the 

treated surface. Increasing levels of PPE is not considered a viable approach for mitigating postapplication risks so PPE is not used when calculating MOEs for re-entry workers; instead, the 

MOE is calculated for 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 application 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 application. 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). The Agency concludes that simazine 

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 involved 

irritant effects to the eyes, skin and respiratory passages and several involved 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 acutely toxic than other 

pesticides. The overwhelming majority of symptoms reported due to simazine exposure were 

eye, dermal, and throat irritation. 74 cases involving simazine were reported to the California 

Pesticide Illness Surveillance Program from 1982-1999. Nine of these cases either involved the 

use of simazine alone 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 registrant-submitted studies or studies available in open literature. Acute 

ecotoxicity values reflect the doses or concentrations that, in an acute toxicity 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, simazine is non-toxic to estuarine/marine fish and 

invertebrates at the limits of its water solubility; practically 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 effect concentration” or 

NOAEC. For simazine, the chronic effects in birds are based on reproductive endpoints (a 

decrease 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, the 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. Risk 

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 pesticide 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 in the environment at levels that could significantly 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 products containing 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 formulations 

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 plants. A preliminary assessment was also 

completed for Federally Listed Threatened and Endangered Species (Listed Species). Based on 

the mobility and persistence of simazine, simazine’s mode of action, and the potential dietary 

exposure to simazine of aquatic 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 moderately 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 soil 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, especially 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 bioaccumulate 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 movement 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). 

Simazine’s chlorinated degradates DIA and DACT are shown in studies to be more mobile than 

simazine, and therefore more likely to leach to ground water than the parent compound. 

Hydroxy-atrazine, on the other hand, is less mobile than simazine, and has less leaching potential 

than the parent compound. Based on data from the registrant-supported drinking water 

monitoring programs VMP and AMP, and the concentration of simazine’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. 

Page 33 of 266 
2. Aquatic Organism Exposure and Risk 

While several sources of monitoring data, including the VMP/AMP database, were used 

to understand the potential concentrations of simazine in surface water, EECs were estimated for 

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 simazine 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 aquatic 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 nectarines), and lettuce (as 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 practices, 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 

similar 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 invertebrates because acute 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 effects 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 

minnow 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, acute 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 potential for direct adverse acute effects 

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-vascular aquatic plants range from below the LOC to 9.33. The 

Agency does not currently assess chronic risks to plants. 

Two important considerations relative to simazine’s potential to affect plants are recovery 

and potential resistance of some species. Recovery 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 estimated for terrestrial organism risk calculations by estimating pesticide 

residue on food items for birds and mammals, 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 modeling for seven crop scenarios including citrus, pine trees, grapes, nuts, corn, 

almonds/fruit, and strawberries. For granular formulations, EECs were estimated for mammals 

and birds based on an assumption that all of the granules are unincorporated in the 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 bioaccumulated 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 drift 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, potential 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. Instead EECs 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-granular 

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, based 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, chronic RQs calculated for mammals reach a maximum of 230 and 

exceed 50 in five of the 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 

formulations calculated for birds and mammals with those RQs bolded that exceed the Agency’s 

LOC of 1.0 for chronic risk 

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 indicate 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 RED for simazine, the Agency completed a preliminary or screeninglevel assessment 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 acknowledges 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 included 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 conservation 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 taxonomic 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 nonselective weed control on turf and other non-crop land as 

well as apples; 

• Vascular 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 plants 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 plant species (plant 

dependent) 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 chronic RQs exceed the Agency’s LOC for ecological 

risk to Listed Species. Those RQs which exceed the Agency’s LOC are bolded.

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 specific 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 pesticide 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 pesticide in 

specific geographic areas, those changes to the 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 were reviewed 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 lakes, flowing 

water, or ponds with outflow. 

Page 41 of 266 
Two incidents for terrestrial 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 swimming 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 of 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 the 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 to 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 reassessment process under FFDCA and reregistration process under 

FIFRA, as amended by FQPA. The Agency has determined that products containing simazine 

are eligible for reregistration provided that the risk mitigation measures outlined 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 table of those 

uses eligible for reregistration. Appendix B identifies generic data requirements that 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 satisfied with acceptable data or additional data 

requirements necessary to confirm the decision presented here. 

Should a registrant fail to implement any of the risk mitigation measures identified in this 

document, the Agency may take appropriate regulatory action 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 risks associated with the chlorinated 

triazine class of pesticides, including simazine, are below the Agency’s level of concern. 

Therefore, if all changes outlined in this document are incorporated into the product labels, then 

all current risks for simazine will be adequately addressed for the purposes of this determination 

Page 42 of 266 
under FIFRA. Once a comprehensive endangered 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 these regulatory decisions for simazine. During the public comment period 

on the risk assessments, which closed on September 12, 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 registrant), and Florida Department of Agriculture & 

Consumer Services. These comments expressed agreement with some portions of the risk 

assessments, argued that the risk assessments 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 are available 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 process, EPA assessed the risks associated 

with simazine. The Agency has concluded that, 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 special 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 has completed its cumulative risk 

assessment 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 are below the Agency’s level of concern. 

Page 43 of 266 
The Agency has determined that tolerances for simazine meet the FQPA safety standards 

and are now considered reassessed. 

b. Determination of Safety to U.S. Population (Including Infants and 

Children) 

The Agency has determined that the established tolerances for simazine, with label 

amendments and changes as specified in this document, meet the safety standards under the 

FQPA amendments to Section 408(b)(2)(C) and 408(b)(2)(D) of the FFDCA, and that there is a 

reasonable certainty that no harm will result to the general U.S. population, infants, children, or 

other major identifiable subgroups of consumers, from the use of simazine. The safety 

determination considers factors such as the toxicity, use practices and exposure scenarios, and 

environmental behavior 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 neuroendocrine 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 factor 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. When drinking water concentration values were 

estimated using modeling, which the Agency believes is conservative and protective, the 3X for 

exposure-based uncertainty was unnecessary for inclusion in the chronic dietary assessment. 

The 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 Procedures using 

high-end default values 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 under 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 estrogen, or other endocrine effects as the 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 that 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 Endocrine Disruptor Screening 

Program (EDSP). 

There is direct evidence that simazine is associated with neuroendocrine disruption. 

Direct measurements of serum hormones such as certain steroid hormones and luteinizing 

hormone, as well as changes in estrus cycling 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 neuroendocrine 

disruptor effects and requiring risk mitigation measures, label amendments, and additional 

confirmatory data to reduce potential risks to below the Agency’s leve ls of concern. The Agency 

has determined that, with label amendments and changes as specified in this document, there is a 

reasonable certainty that no harm will result to the general U.S. population, infants, children, or 

other major identifiable subgroups of consumers, from the use of simazine. When the 

appropriate screening and/or testing protocols being considered under 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 determining 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 by 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 person 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 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 OPP concerning common mechanism determinations and procedures for 

cumulating effects from substances 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 considered 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 assessment 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 are below 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 identifiable subgroups of consumers, from the use of 

simazine, atrazine, and propazine. The cumulative risk assessment and supporting documents 

are available in the public docket EPA-HQ-OPP-2005-0481 located on-line in FDMS, 

http://www.regulations.gov. 

2. Tolerance Summary 

A tolerance summary and tolerance reassessment decision is presented for simazine in 

Table 11 below. Currently there are 62 tolerances listed in 40 CFR 180.213 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 commodities 

are simazine and its two chlorinated degradates, DIA and DACT. The Agency will propose 

changing the tolerance expression for all commodities to reflect combined residues of the parent 

compound, simazine (2-chloro-4,6-bis(ethylamino)-s-triazine), plus its two chlorinated 

degradates (2-amino-4-chloro-6-ethylamino-s-triazine and 2,4-diamino-6-chloro-s-triazine), the 

total residue to be measured in/on raw agricultural commodities for tolerance enforcement. 

The crop and animal commodity tolerances which the Agency will propose to revoke 

because the registrants are not supporting related uses 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 propose to revoke the 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 byproducts), 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 preharvest 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 tolerance. 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 be proposed, 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 does not currently have MRLs for simazine.

D. Regulatory Rationale

The Agency has determined 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. The 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 Drinking Water) 

As discussed in Sections III.A.2 and 3, acute dietary risks (from food and drinking water) 

do not exceed the Agency’s level of concern. Additionally, chronic risks from food alone do 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 simazine 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 water 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 when 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 results 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-selective weed control on non-crop land” on product labels; 

• prohibit aerial application and add a statement to product labels indicating this 

prohibition; and 

• reduce maximum application rates to typical rates (as specified in Section V, 

Table 13) and harmonize 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 from wells and waterways in addition to restrictions for use in tileoutletted 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 

chlorinated degradates. As further detailed 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 grass 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 incorporated 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 

removed from 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 monitoring 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 exceeds, or is predicted to exceed, the chronic 

DWLOC for infants and children, 12.5 ppb total. Six CWS, listed below, 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, then additional 

mitigation measures will be required at the associated watershed(s). Further details 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 MUPs is included as 

Appendix J. 

Page 50 of 266 
As with atrazine, exceedances do not appear to be linked to nation-wide use practices that 

can be amended on the label but rather to watershed 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 mitigation 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 January 2003 

Water Quality Trading Policy. This policy encourages solutions within watersheds, 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 because 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 programs being implemented and coordinated for atrazine by the simazine 

technical registrants, all of whom are also technical registrants 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 the 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 program, 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 Illinois, 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 

surface water 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 required for all 

simazine products as described above, is necessary at this CWS at this time. Simazine usage 

data available to the Agency indicates that a majority of simazine used in the Midwest is tank 

mixed with atrazine, and therefore use restrictions (e.g., setbacks from waterways, restrictions 

for use in tile-outletted terraced 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. Additionally, concentrations 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 
The Agency has also considered available data from SDWA compliance monitoring, 

which typically 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 predictor that the 12.5 

ppb DWLOC could be exceeded. Based on SDWA compliance data from 1997 to 2004, five 

additional CWS have been 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 three chlorinated degradates as part of the atrazine 

surface water CWS monitoring program. 

CWS in the program will be subject to an intensive monitoring schedule that will include 

weekly monitoring for simazine and its two chlorinated degradates in raw water at the water 

intake during the simazine use season and biweekly monitoring for simazine and its two 

chlorinated degradates in raw water during the remainder of the year. Appendix J includes a list 

of the use season for simazine by state, and subsequently 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 based on 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 

understands that technology is now available which allows for the collection of measured values 

for all chlorinated degradates as well as the triazine parent compound s. Thus, the 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 simazine 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 water 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 remainder of the 

year) monitoring. One exception is that if a CWS has an annua l average concentration of 2.6 

ppb or greater based on 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 exceeded based on 

the four samples, and if so, putting the CWS into the 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 program 

the year following the measurement. Should the CWS to be added to the monitoring program be 

in a state or states not listed in Appendix J, EPA will determine the corresponding simazine use 

season in the state(s) to identify the appropriate monitoring schedule for the CWS. 

Page 52 of 266 
The technical registrants must 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 measurements of the parent 

compound only in finished water, and use of the regression equation developed for simazine. 

The deadline for identification of CWS from 2005 SDWA compliance data is May 30, 2006, 

rather than April 1, to allow sufficient time for analysis 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, technical 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. The SWIC must be accessible to the public daily, including weekends and holidays, 

through a toll-free number available 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 13 below), all simazine products, except those labeled only for use by homeowners on 

turfgrass or labeled only for use as an algaecide, will be required to bear labels containing the 

following statements, 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 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 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 monitoring 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-based 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 performance standard that 

must be met in any CWS that is being intensively 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. However, 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 average 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 37.5 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 result. 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 submit to the EPA, and begin implementing within 90 

days of the exceedance, a written mitigation plan including mitigation measures to be 

implemented within the watershed 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 strips, 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 

exceeded in 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 the technical 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 gallons 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 subject to the use prohibition so as to 

describe this 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 watershed area listed in the SWIC. Corresponding label 

language is specified in Section V, Table 13. 

If a CWS is reported to EPA to be in violation of the simazine MCL, the technical 

registrants must consult with the State Drinking Water Administrator 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, then 

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. Revised Model Concentrations and Additional 

Confirmatory Data Needs 

For those scenarios in which the concentration of simazine was 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 degradates in drinking water based 

on the mitigation measures. While the predictive model PRZM/EXAMS suggests 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 and 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 conservative and likely overestimates the total concentration due to the 

equation’s derivation from data collected on degradates which can result from both simazine and 

atrazine. Further, the data used to derive the equation were collected in areas with a history of 

atrazine use and 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. For 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 vulnerable to simazine contamination. 

The Agency also intends to require as confirmatory data a prospective ground water 

monitoring study to be completed in Florida. 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 37.5 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 confirmatory 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, and 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 required at a later date if necessary as determined by the results of the prospective ground 

water monitoring study. 

b. Residential Risk Mitigation

As discussed in Section III.A.4, there are potential short-term risks of concern from 

homeowner exposure to simazine when loading/applying granules via a belly grinder to 

turfgrass, but post-application risks to toddlers, youths, and adults do not exceed the Agency’s 

level of concern. 

To reduce homeowner handler 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 Agency’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 residential 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 Agency’s levels of concern for all subpopulations, including infants and 

children less than 1 year old. 

d. Occupational Risk Mitigation

As discussed in Section 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 containing 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 labels; 

• prohibit formulation of simazine into wettable powder formulations ; 

• prohibit formulation of simazine into granular formulations for occupational use, 

which includes uses covered under the WPS and non-WPS commercial uses; 

• prohibit aerial application and add a statement to product labels indicating this 

prohibition; and 

• reduce application 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 specified in Section V, Table 13) and 

harmonization of application rates on simazine product labels will further reduce occupational 

handler exposure to simazine for various scenarios. In order to eliminate the need to use 

engineering controls with dry flowables 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 

“Review of Simazine Dry Flowable Exposure Scenario for Applications to Corn, Grapes, and 

Florida Oranges, D307039,” dated January 30, 2006, the Agency has also determined that 

intermediate-term exposure will not occur when occupational handlers are mixing/loading dry 

flowable and liquid formulations for chemigation application, so PPE or engineering controls to 

address these scenarios are unnecessary. 

Page 56 of 266 
The recalculated MOEs, based on the mitigation measures and additional reduced rates, 

are available in the document “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 handler risks below the Agency’s level of concern is chemical-resistant gloves (as 

specified in Section V, Table 13). In addition to gloves, mixer/loaders of dry flowable 

formulations supporting groundboom applications need to wear coveralls over their long-sleeve 

shirts and pants, chemical-resistant footwear, and PF 5 NIOSH-approved respirators 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 concern. 

The Worker Protection Standard for Agricultural Pesticides requires a restricted-entry 

interval (REI) of at least 12 hours for all uses and this REI must appear on all product labels. 

There are two uses for which potential risks of concern exist after 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 an REI for Christmas trees of 48 hours on product labels; 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/A through a statement on products labels. 

2. Ecological Risk Management and Mitigation 

As discussed 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 in the following 

taxonomic groups from exposure to 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 from 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 direct adverse 

chronic effects, 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 available 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 typical 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 these 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, the 

Agency believes that these estimates are conservative since they consider 100% of the 

organism’s diet is from areas treated with simazine. Additionally, the prohibition of aerial 

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 use and restricting spray drift 

(as further detailed in Section V, Table 13), will have an overall effect of reducing aquatic and 

terrestrial organism exposure to simazine. 

The Agency intends to require confirmatory acute toxicity data on freshwater fish 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 ecotoxicity data on simazine’s two chlorinated degradates for all taxonomic groups 

except 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 simazine in 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 be included in the labeling of all end-use products containing simazine. For the specific 

label statements and a list of additional data requirements necessary to confirm 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 effects was 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 threatened and endangered species and to 

implement mitigation 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 registered 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 species 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. 

Following 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 and 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 specific 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 amendments are made 

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 request 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 data and amend labels. In 

order for simazine to be eligible for reregistration, all product 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. The Agency intends to issue a generic DCI 

for this data.

2. Labeling for Manufacturing-Use Products 

To ensure compliance with FIFRA, labeling for all MUPs should be revised to comply 

with all current EPA regulations, PR Notices, and applicable policies. The MUP labeling should 

bear the specific language presented in Table 13 below. 

B. End-Use Products 

1. Additional Product-Specific Data Requirements 

Section 4(g)(2)(B) of FIFRA calls for the Agency to obtain any needed product-specific 

data regarding the pesticide after a determination of eligibility has been made. The registrant 

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 numbers 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, labeling changes are necessary to implement measures 

outlined in Section IV above. The specific changes and language are presented in Table 13 

below. Generally, 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 products involved, the 

number of label changes, and other factors.

Appendix B. Table of Generic Data Requirements and Studies Used to Make the 

Reregistration Decision 

Guide to Appendix B 

Appendix B contains listing of data requirements which support the reregistration for active 

ingredients within case #0070 (simazine) covered by this RED. It contains generic data 

requirements that apply to simazine in all products, including data requirements for which a 

"typical formulation" is the test substance. 

The data table is organized in the following formats: 

1. Data Requirement (Column 1). The data requirements are listed in the order in which 

they appear in 40 CFR part 158. The reference numbers accompanying each test refer to 

the test protocols set in the Pesticide Assessment Guidance, which are available from the 

National technical Information Service, 5285 Port Royal Road, Springfield, VA 22161 

(703) 487-4650. 

2. Use Pattern (Column 2). This column indicates the use patterns for which the data 

requirements apply. The following letter designations are used for the given use patterns. 

A. Terrestrial food 

B. Terrestrial feed 

C. Terrestrial non-food 

D. Aquatic food 

E. Aquatic non-food outdoor 

F. Aquatic non-food industrial 

G. Aquatic non-food residential 

H. Greenhouse food 

I. Greenhouse non-food 

J. Forestry 

K. Residential 

L. Indoor food 

M. Indoor non-food 

N. Indoor medical 

O. Indoor residential 

3. Bibliographic Citation (Column 3). If the Agency has acceptable data in its files, this 

column list the identify number of each study. This normally is the Master Record 

Identification (MIRD) number, but may be a "GS" number if no MRID number has been 

assigned. Refer to the Bibliography appendix (Appendix D) for a complete citation of 

the study.

Appendix D. Citations Considered to be Part of the Database Supporting the 

Reregistration Decision (Bibliography) 

Guide to Appendix D 

1. Contents of Bibliography. This bibliography 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 submitted 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 in 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 published 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 bibliographic 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) below 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 be used 

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 earliest 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 chosen 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 author. 

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 was 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 parentheses. 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 submission 

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 

associated 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 identifies 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 alphabetic 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 

the preceding paragraph. Notwithstanding the batching process, 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 toxicological 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 the 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 submitted 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 not 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 than 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: Developing 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 accordance 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. 

NOTE: 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.

Page 260 of 266 
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] be amended 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 included 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 to the 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 reformulated 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 Decision (RED)." 

ii) "No product other than a product labeled only for use by homeowners on 

turfgrass 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 for 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 turfgrass 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 within 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; and 

(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 to 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 Pesticide 

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 offering 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 Simazine 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 monitoring program in paragraph 3)c) below. (Except, 

that if a CWS has an annual average based on a single sample equal to or greater 

than 2.6 ppb Simazine and its two chlorinated degradates but less than 4.0 ppb 

Simazine (parent compound only), then [Registrant] has 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 the 

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 will 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 review of SDWA data pursuant to 

paragraph 3)a) noted above; and 

iii) Any other CWS that has a surface water source and for which any reliable 

data indicates an annual concentration of 2.6 ppb or more Simazine and its 

two chlorinated degradates in finished water or a concentration 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 based 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 chlorinated degradates in raw water at the water 

intake weekly during peak use seasons based 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 passed without any 

90-day rolling 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 implemented 

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 timing, 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 

Drinking 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 to EPA 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 be 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 algaecide). 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 

conditions. 

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].
