1. EXECUTIVE SUMMARY 

The Environmental Fate and Effects Division (EFED) conducted a drinking water 

exposure assessment for the new chemical indaziflam, (BCS-AA10717), N-[(1R,2S)-2,3-

dihydro-2,6-dimethyl-1H-inden-1-yl]-6-[(1RS)-1-fluoroethyl]-1,3,5-triazine-2,4-diamine (CAS#: 

950782-86-2; PC code: 080818). Indaziflam is an alkylazine herbicide proposed for selective 

pre emergence and post emergence control of many annual grasses and broadleaf weeds on 

residential turf, ornamentals, hardscapes, golf courses, ball parks, commercial forests, Christmas 

tree farms, citrus fruit, stone fruit, pome fruit (apples, pears, quinces, and Asian pears), grapes, 

tree nuts, and olives. Indaziflam controls weeds by inhibiting cellulose biosynthesis (CB 

Inhibitor). Its primary sites of action are inhibition of seedling emergence and root development. 

This assessment is based on proposed maximum application rates for all uses. 

EFED calculated drinking water concentrations for total indaziflam residues which 

includes indaziflam and similarly structured degradates. EFED also calculated concentrations 

separately for the indaziflam degradate, floroethyl-diaminotriazine (diaminotriazine, FDAT) plus 

floroethyl-dihydroaminotriazine (dihydroaminotriazine, ROI1; a degradate of diaminotriazine), 

which the Residues of Concern Knowledgebase Subcommittee (ROCKS) reported to be of 

toxicological concern (D371659). ROCKS also reported that the four major transformation 

products that maintain the dual ring structure of the parent indaziflam should be included in the 

drinking water exposure assessment since they may be of toxicological concern (i.e., they are 

assumed to be of equal toxicity to the parent in the absence of toxicological data). These 

transformation products include: triazine indanone, indaziflam-carboxylic acid, indaziflamolefin, and indaziflam-hydroxyethyl. Drinking water concentrations to be used in HED’s human 

health risk assessment are included in Table 1.1 for indaziflam + similarly structured 

transformation products and in Table 1.2 for diaminotriazine. Bold values indicate the 

maximum concentrations for surface water and ground water.

 Field and laboratory data indicate that indaziflam and, more importantly, its residues have 

a potential to leach to ground water. Indaziflam is classified as moderately mobile, however 

transformation products of indaziflam are mobile to highly mobile and were detected in field 

studies at depth. Further, data show that indaziflam is persistent in anaerobic soil and anaerobic 

aquatic systems. There are no data available on the anaerobic degradation of the transformation 

products of indaziflam. Key lines of evidence show that residues of indaziflam are a concern for 

exposure via ground water. However, there is uncertainty regarding the toxicity of indaziflam 

residues. Requiring a prospective ground water study could help reduce the uncertainty 

regarding the exposure via ground water. 

 Further, in the field studies, the limit of detection (LOD) for parent indaziflam and its 

transformation products was 0.3 ng a.i./g, and the limit of quantitation (LOQ) was 1.5 ng a.i./g 

for all studies. Substantial concentrations of indaziflam and its major transformation products 

were reported between the LOD and the LOQ in all field studies. Detections below the LOQ are 

not accurately characterized because of the gap between the LOD and the LOQ; therefore, the 

analytical method may have been too insensitive to accurately describe the leaching potential of 

indaziflam and its major transformation products. Replicate values below the LOQ were 

assumed at 1⁄2(LOQ + LOD) for calculations of dissipation half-lives. 

2. PROBLEM FORMULATION 

 This drinking water exposure assessment (DWA) uses modeling to estimate the surface 

water and ground water concentrations of indaziflam residues in drinking water source water 

(pre-treatment) resulting from proposed labeled use on sites that are considered vulnerable to 

pesticide contamination resulting from labeled use practices. Estimated drinking water 

concentrations (EDWCs) are included for indaziflam + structurally similar transformation 

products, and for the degradate diaminotriazine. The coupled models PRZM and EXAMS were 

used to assess exposure in surface water due to runoff and drift from the proposed indaziflam 
Page 4 of 131 

uses. Exposure in ground water due to leaching was assessed with the screening model SCIGROW. 

The major degradates observed in laboratory and field studies are summarized in Table 

2.1. The table also shows the fate studies in which the degradates were identified and the 

maximum formation in each study. The Health Effects Division (HED) has reported that all 

transformation products that maintain a similar chemical structure to the parent (dual triazine and 

indane rings - - triazine indanone, indaziflam-carboxylic acid, indaziflam-olefin, indaziflamhydroxyethyl), and the diaminotriazine degradate are of toxicological concern. This assessment 

includes consideration for the exposure of both indaziflam + similarly structured transformation 

products and diaminotriazine, which are addressed separately.

2.1. Background 

Bayer CropScience is seeking registration for the use of the new chemical herbicide 

indaziflam (BCS-AA10717), N-[(1R,2S)-2,3-dihydro-2,6-dimethyl-1H-inden-1-yl]-6-[(1RS)-1-

fluoroethyl]-1,3,5-triazine-2,4-diamine. Indaziflam is an alkylazine herbicide that is expected to 

be moderately mobile in soil, moderately persistent to persistent in aerobic soil, persistent in 

aquatic environments, and persistent under anaerobic conditions (both terrestrial and aquatic). 

Indaziflam controls weeds by inhibiting cellulose biosynthesis (in the class of herbicides known 

as CB Inhibitors). Its primary sites of action are inhibition of seedling emergence and root 

development. Indaziflam is a mixture of two active diastereoisomers (AE 1170437 (isomer A), 

and AE 1170438 (isomer B)), which are both present in the technical grade product in the 

following percentages: 95-100% isomer A, and 0-5% isomer B. This assessment is part of a 

national registration request for selective pre emergence and post emergence control of many 

annual grasses and broadleaf weeds including crabgrass, goosegrass, annual bluegrass, and 

annual sedges in turf, citrus fruit, stone fruit, pome fruit, grapes, tree nuts, pistachios, and olives, 

ornamentals, trees and on hardscapes. 

 Eleven end-use formulations of indaziflam are proposed for registration in the United 

States that include the following: 

1. BCS AA10717 20 WSP: 20% indaziflam; used on athletic turf (sports turf), golf courses 

(prohibited on greens), sod farms, ornamentals, nurseries, Christmas trees, landscape 

plantings, forestry, and non-crop areas. 

2. Esplanade F: 19.05% indaziflam; used on forested areas. 

3. Esplanade 200 SC: 19.05% indaziflam; used on non-crop areas, railroad and rail yards, 

managed roadsides, established ornamental and perennial plantings, fence rows, utilities, 

hardscapes and other industrial, municipal and government sites, and under asphalt or 

concrete as part of site preparation. 

4. Lawn 3FL Herbicide (Ready-to-Use): 0.0031% indaziflam; 0.309% 2,4-D, 

dimethylaminie salt; 0.034% dicamba, potassium salt; 0.073% mecoprop-p, potassium 

salt; used on established southern home lawns. 

5. Lawn 3FL Herbicide Granule: 0.05% indaziflam; 0.11% dicamba acid; 0.06% 

penoxsulam; used on established southern home lawns. 

6. Lawn 3FL Herbicide Concentrate (Ready-to-Spray): 0.25% indaziflam, 4.89% 2,4-D, 

dimethylaminie salt, 0.54% dicamba, potassium salt, 1.15% mecoprop-p, potassium salt; 

used on established southern home lawns, ornamentals, and hardscapes. 

7. BCS-AA10717 0.0284% Plus Turf Fertilizer (Granule): 0.0284% indaziflam; used on 

athletic turf (sports turf), golf courses (prohibited on greens), and sod farms 

8. BCS-AA10717 0.0213% Plus Turf Fertilizer (Granule): 0.0213% indaziflam; used on 

athletic turf (sports turf), golf courses (prohibited on greens), and sod farms 

9. BCS-AA10717 0.0142% Plus Turf Fertilizer (Granule): 0.0213% indaziflam; used on 

athletic turf (sports turf), golf courses (prohibited on greens), and sod farms 

10. Indaziflam 200 SC Herbicide: 19.05% indaziflam; used on citrus fruit, stone fruit, pome 

fruit, grapes, tree nuts, pistachios, and olives. 
Page 6 of 131 

11. Indaziflam 500 SC Herbicide: 45.05% indaziflam; used on citrus fruit, stone fruit, pome 

fruit, grapes, tree nuts, pistachios, and olives. 

2.2. Use Characterization 

 Indaziflam is proposed for use as a selective pre emergent weed control in perennial tree 

and vine crops (Citrus, Stone Fruit, Pome Fruit1

, Grapes, Tree Nuts, Pistachios, Olives), pre 

emergent and post emergent weed control on athletic turf (golf courses, athletic fields, parks, 

recreation areas, and sod farms), home lawns, ornamentals and hardscapes (sidewalks, 

driveways), commercial forests, Christmas tree farms, and other non-crop areas (railroad and rail 

yards, managed roadsides, fence rows, utilities, other industrial, municipal, and government 

sites). End-use products assessed in this document are formulated as a dry granule (Lawn 3FL 

Herbicide Granule), water soluble packets (BCS-AA10717 20WSP), liquid concentrate (Lawn 

3FL Herbicide Concentrate), suspension concentrate (Indaziflam 500 SC Herbicide, Indaziflam 

200 SC Herbicide, Esplanade 200 SC, Esplanade F), three granular herbicide plus fertilizer 

products (BCS-AA10717 0.0284% Plus Turf Fertilizer, BCS-AA10717 0.0213% Plus Turf 

Fertilizer, BCS-AA10717 0.0142% Plus Turf Fertilizer), and a multi-a.i. ready-to-use spray 

(Lawn 3FL Ready-to-Use Spray). 

 Maximum application rates and management practices listed by use according to the 

proposed labels are listed in Table 2.2. Indaziflam 200SC and Indaziflam 500SC have higher 

single maximum application rates for fine textured soils than for coarse textured soils (0.085 lbs 

a.i/A and 0.065 lbs a.i./A, respectively). The fine textured soil application rate (0.085 lbs a.i./A) 

was used for modeling in this exposure assessment. For purposes of this assessment, drinking 

water exposure estimates are based on maximum proposed label rates for six use categories: food 

(citrus, stone fruit, tree nuts, and vine crops), turf (golf courses, athletic fields, and sod farms), 

residential lawns, ornamentals and hardscapes, forestry, and other non-crop areas (railroad and 

rail yards, managed roadsides, fence rows, utilities, other industrial, municipal, and government 

sites).

maximum rate of 0.134 lbs a.i./A). For turf uses a single maximum application rate of 0.08 lbs a.i./A is permitted with a second application of 0.02 lbs 

a.i./A. 

†† Other non-crop areas are, as defined by the proposed label: Railroad and Rail Yards, Managed Roadsides, Fence Rows, Utilities, Other Industrial,

2.3. Conceptual Model 

Indaziflam is a moderately mobile to mobile chemical that is expected to be relatively 

persistent in the environment in aerobic conditions, and persistent in anaerobic conditions. 

Residues of concern for exposure include triazine-indanone, diaminotriazine, indaziflamcarboxylic acid, indaziflam olefin, and indaziflam-hydroxyethyl. Residues of concern are more 
Page 8 of 131 

mobile than the parent compound. Indaziflam and its residues are likely to reach surface water 

resources via spray drift or runoff, and ground water resources via leaching from use sites. 

3. ANALYSIS 

3.1. Fate and Transport Characterization 

 The general physical/chemical properties of indaziflam are summarized in Table 3.1. 

Environmental fate and transport properties of indaziflam are characterized in further detail in 

the following sections. Our understanding of these properties is limited by the data set available. 

Many of the chemical properties and environmental fate parameters of indaziflam listed in Table 

3.2 are based on single, supplemental studies. Table 3.3 lists the available chemical properties 

and environmental fate parameters for diaminotriazine. Drinking water exposure estimates were 

generated for this major degradate.

 Indaziflam is expected to be moderately mobile in soil, moderately persistent to persistent 

in aerobic soil, persistent in anerobic soil, and persistent in aerobic and anaerobic aquatic 

environments. Indaziflam is a racemic mixture of two stereoisomers with a ratio of isomer A to 

isomer B as high as 19:1. Both active isomers (N-[(1R,2S)-2,6-dimethyl-2,3-dihydro-1H-inden1-yl]-6-[(1R)-1-fluoroethyl]-1,3,5-triazine-2,4-diamine and N-[(1R,2S)-2,6-dimethyl-2,3-

dihydro-1H-inden-1-yl]-6-[(1S)-1-fluoroethyl]-1,3,5-triazine-2,4-diamine) have similar 

environmental fate characteristics (aerobic soil metabolism half-lives in two soil types reported 

at 45 and 65 days isomer A, and 55 and 89 days isomer B; MRID 47443215). Based on the 

chemical structure of the compound and location of the chiral center, it is expected that the two 

isomers will behave similarly in the environment and have similar toxicity. Submitted fate 

studies were completed using isomer A, and are reported in Tables 3.1-3.2. 

 Indaziflam and its residues of concern are expected to persist in both the terrestrial and 

aquatic environments, the compound is stable to hydrolysis but can degrade through aqueous 

photolysis. Under aerobic conditions, the compound can be slowly metabolized, but it is stable 

to anaerobic metabolism. Indaziflam is moderately mobile to mobile based on the FAO Soil 

Mobility Classification Guidance (USEPA, 2006). However, major degradates of indaziflam are 

more mobile than the parent, particularly diaminotriazine which was detected in field studies at 

the maximum soil segment depth, and was detected over multiple time points. Indaziflam was 

detected in the submitted terrestrial field dissipation studies above the level of quantitation 

(LOQ) at depths up to 45-60 cm; however the majority of detections were restricted to the 0-15 

cm range in the soil profile, with a few detections above LOQ in the 15-30 cm, and 30-45 cm 

depth. It was also detected below the LOQ at a maximum depth sampled. 

 Field dissipation data also indicate that the major transformation products, particularly 

diaminotriazine, may have a higher potential to leach compared to the parent and are more 

persistent with half-lives on an order of magnitude greater than the calculated parent dissipation 

half-lives. Indaziflam and, more importantly, its degradates are a concern for exposure in ground 

water. The high mobility and persistence of the degradates, and data from field studies indicate 

that degradates of indaziflam will leach to ground water, specifically diaminotriazine. That 

compound was detected at deeper depths in the field studies compared to the other degradates, 

and is highly mobile. A prospective ground water study (PGW) would help to further 

characterize the extent of the potential impact on ground water quality.

 Microbial biomass in this study was approximately 7x higher than the two other sites. †† Dihydroaminotriazine (ROI1) was only detected in the Laacherhof sandy loam soil at a maximum percentage of 21% of the AR, 58 DAT. 

‡ Dissipation half-lives were calculated for diaminotriazine based on data from studies conducted using the parent indaziflam from 28-531 days 

after treatment (MRID 47443223), and 134-526 days after treatment (MRID 47443224). 

‡‡ Data was inadequate to calculate half-life or regression was insignificant (p > 0.05), therefore half-life was not calculated.

3.1.1. Transport and Mobility 

 Indaziflam is not volatile, with a partial vapor pressure of 5.1 x 10-10 and 8.25 x 10-11 torr 

at 25oC, for isomer A and B, respectively (MRID 47443202). The compound exhibits acid-base 

behavior (pKa = 3.5 and 3.6, isomer A and B, respectively; MRID 47443202), is neutral at 

environmental pH values and it is moderately soluble at environmental pHs 4, 7 and 9 (isomer A: 

4.4, 2.2, 2.2 mg/L, and isomer B: 1.7, 1.2, and 1.2 mg/L; MRID 47443202). . The reported Kow

for indaziflam at 40oC for pH 7 was 631, where pH>pKa, and was undetermined at pH< pKa

(MRID 47443202). 

 Indaziflam is moderately mobile to mobile based on FAO Soil Mobility Classification 

Guidance (USEPA, 2006), with reported Freundlich adsorption values (Kf) from five soils 
Page 13 of 131 

ranging from 6.1 to 11.1 (0.885) (MRID 47443203). Batch equilibrium data for indaziflam show 

that adsorption to soil is not well correlated with organic carbon content. The coefficient of 

variation (CV) for Koc (27%) is larger than that for Kf (21%). Further, Kf was not well correlated 

with percent organic carbon (r2

 = 0.187, p = 0.47), nor with pH (r2 = 0.001, p = 0.95), nor percent 

clay (r2

 = 0.005, p = 0.91). 

 Leaching and adsorption/desorption studies were conducted on the identified three major 

degradates1: triazine-indanone, diaminotriazine, and indaziflam-carboxylic acid. These 

compounds are more mobile than the parent. Diaminotriazine and indaziflam-carboxylic acid 

have low soil-water partitioning coefficients (respective Kf values ranged from 0.16 to 0.78 and 

from 0.47 to 1.32). Diaminotriazine and indaziflam-carboxylic acid are mobile to highly mobile 

compounds, based on the FAO Soil Mobility Classification Guidance (USEPA, 2006). Triazineindanone is moderately mobile in soil, although still more mobile than the parent indaziflam (Kf

ranging from 3.00 to 5.97; MRID 47443204). 

 Compounds with Kf values less than five trigger a ground water advisory (USEPA, 

2008a). The major degradates of indaziflam (triazine-indanone, diaminotriazine, and indaziflamcarboxylic acid) present a potential ground water concern in some soils, especially those that are 

sandy and have low organic carbon content (all Kf values are less than 5; MRID 47443204, 

47443205, 47443206). 

3.1.2. Degradation 

 Indaziflam is stable to hydrolysis; there was no evidence of degradation at pH 4, 7, and 9 

at 50oC (MRID 47443207). It is rapidly photolyzed in water (combined label, corrected 

environmental half-life of 3.7 days at pH 7; MRID 47443208) and photodegrades comparatively 

slow in soil (continuously irradiated, combined label, corrected environmental photodegredation 

half-life in soil of 40.3 days in loamy sand at pH 6.5, OC 2.4%; MRID 47443209). 

 Indaziflam biodegrades in 35 to 178 days in aerobic soil (parent-only half-lives; MRID 

47443210, 47443211, 47443212, 47443213). Un-extracted residues were substantial (17 – 34 

%) in all aerobic soil metabolism studies. Multiple solvent systems were not employed in the 

extraction scheme; therefore it is uncertain whether the un-extracted residues are parent, 

degradates, or bound residues. Thus half-lives were calculated for both parent-only and parent 

and un-extracted residues combined (parent and un-extracted residues half-lives of 71 to 630 

days). 

 

 Results from the four aerobic soil metabolism studies on six different soil types show 

indaziflam degrades via oxidation of the indanyl moiety to indaziflam-triazine indanone and 

indaziflam-carboxylic acid. Indaziflam, indaziflam-triazine indanone and indaziflam-carboxylic 

acid are cleaved at the N bridge to form diaminotriazine from the triazine moiety and 

unidentified minor compounds from the indanyl moiety. Residues are ultimately converted to 

bound residues and CO2. Figure 3.1 illustrates a predicted degradation pathway under aerobic 

conditions.

 A major degradate is defined as a compound that is detected in the fate studies at > 10% of the applied radiation, or 

is of toxicological concern. 
Page 14 of 131 

 An aerobic aquatic metabolism study was conducted for indaziflam investigating the 

biotransformation of [triazine-2,4-14C]- and [indane-3-13/14C]-labeled indaziflam in two watersediment systems from Germany: a sand-gravel pit lake water system (Angler Weiher), and a 

loam-pond water system (Hoenniger Weiher). Un-extracted residues were significant in both 

systems (12-15% of the applied radiation; MRID 47443217). Multiple solvent systems were not 

employed in the extraction scheme; therefore it is uncertain whether the un-extracted residues are 

parent residues, metabolite residues, or bound residues. Half-lives were calculated for parent 

only, and for parent and un-extracted residues combined. The rate of biodegradation of 

indaziflam was slower in aquatic environments than terrestrial environments (parent-only nonlinear first order half-life of 120 days (DT90 of 497 days) in the water-sand sediment system at 

pH 7.4-8.6, and 239 days (DT90 of >1000 days) in the water-loam sediment system at pH 6.2-

6.7; MRID 47443217; parent and un-extracted residue non-linear first order half-lives of 257 

days, and 462 days, respectively). The compound quickly dissipated out of the water column 

(water dissipation half-life of 0 to 3 days), and was detected in the sediment. The major 

indentified degradates were triazine-indanone, diaminotriazine, and indaziflam-carboxylic acid. 

In anaerobic aquatic environments, indaziflam is stable to biodegradation; there was no evidence 

of degradation (MRID 47443218, 47443219).

Page 15 of 131 

3.1.3. Field Studies 

 Eight terrestrial field dissipation studies were conducted for indaziflam using five sites in 

the United States. Five studies were conducted on bare ground (MRID 47443223, 47443224, 

47443225, 47443301, 47443302), each with four plots that had <1% slope and no runoff 

collection equipment. Three additional studies were conducted on soil cropped with turf (MRID 

47443220, 47443221, 47443222), each with four plots that had <1% slope and no runoff 

collection equipment. In all eight studies, indaziflam was broadcast once at a target application 

rate of 0.165 kg a.i./ha (0.147 lb a.i./A), which is greater than the proposed maximum application 

rate of 0.125 lb a.i./A (for use on forested areas). Indaziflam dissipation half-lives calculated for 

the total soil profile (0-120 cm) were not significantly different than those from the top 15 cm. 

The results from the field studies show more rapid dissipation under field conditions compared to 

the laboratory degradation studies (dissipation half-lives for indaziflam ranging from 9.3 to 69.3 

days versus laboratory half-lives of 36 to 178 days). This difference could be due to off-site 

movement (for example leaching) which is not tracked in field dissipation studies. 

 Field test sites were analyzed for indaziflam and its major transformation products: 

indaziflam-carboxylic acid, triazine-indanone, diaminotriazine, indaziflam-hydroxyethyl, and 

indaziflam-olefin. The limit of detection (LOD) for parent indaziflam and its transformation 

products was 0.3 μg·kg-1, and the limit of quantitation (LOQ) was 1.5 μg·kg-1 for all studies. A 

substantial number of detections of indaziflam and its major transformation products were 

reported at levels between the LOD and the LOQ in all field studies; replicate values below the 

LOQ were assumed at 1⁄2(LOQ + LOD) for calculations of dissipation half-lives. Detections 

below the LOQ do not allow accurate quantification of these values; therefore, leaching potential 

of indaziflam and its major transformation products may not be accurately described by the data. 

However, data from these eight terrestrial field dissipation studies report indaziflam was detected 

at the deepest increment sampled, and major transformation products were detected at this depth 

at study termination (545 days). These data indicate that indaziflam and more importantly its 

transformation products have a potential to leach to ground water. 

 

 Field dissipation half-lives describe how long residues remain on the target field and in 

the upper portion of the subsurface. They do not differentiate between losses due to degradation 

and losses due to off-site transport (e.g., via runoff to surface water, leaching to ground water, 

eroded soil or by air). Under field conditions, calculated dissipation half-lives ranged from 9.3 

days to 69.3 days; reported DT90s ranged from 109 to 545 days (MRID 47443220, 47443221, 

47443222, 47443223, 47443224, 47443225, 47743301, and 47743302). Two studies reported 

calculated DT90s after the study termination (554 and 545 days, MRID 47443222 and MRID 

47743320). Dissipation half-lives for studies that examined plots cropped with turf were longer 

than those calculated from bare soil sites (9.3 – 59.2 days for bare soil sites and 25.7 – 69.3 days 

for turf sites). Residues were not measured in the turf at any of the three sites cropped with turf 

(MRID 47443220, 457443221, 47443222). The percent carryover for indaziflam + residues of 

concern from year to year ranged from 0.6 to 17%; total carryover for all residues for the entire 

profile ranged from 2.2 to 34%. 

 The most prevalent transformation products in all eight field studies were 

diaminotriazine, triazine-indanone, and indaziflam-carboxylic acid. These compounds were 
Page 16 of 131 

detected in the 0-15 cm depth at maximum mean parent-equivalent concentrations of 17.6% (at 

28 days), 9.1% (at 28 days), and 5.1% (at 28 days) of the theoretical day-0 recovery of 

indaziflam, respectively. Triazine-indanone and indaziflam-carboxylic acid were detected above 

the LOQ at a maximum depth of 15-30 cm. No detections were reported above the LOQ at 

depths below 30 cm for both triazine-indanone and indaziflam-carboxylic acid. However, 

diaminotriazine was detected above the LOQ at a maximum depth of 60-75 cm 59 days after 

treatment; detections below the LOQ were reported at the bottom of the sampled soil profile at 

the study termination (545 days after treatment; MRID 47743302). Studies consistently reported 

detections of diaminotriazine at depths of 60-75 cm, and 45-60cm clearly demonstrating that the 

diaminotriazine degradate has a potential to leach. Detections of both triazine-indanone and 

indaziflam-carboxylic acid, below the LOQ, were reported at a maximum depth of 60-75 cm at 

the study termination (545 days after treatment), indicating that these compounds as well have a 

potential to leach. 

3.1.4. Bioconcentration 

 A flow-through bioconcentration study of bluegill sunfish (Lepomis macrochirus) 

exposed to indaziflam in pH 7.5-8.0 water for 26 days indicates that the compound does not 

bioconcentrate. The 26-day exposure period was followed by a 14 day depuration period. 

Bioconcentration factors (BCF) were 46, 25, and 79x for whole fish, edible, and non-edible fish 

tissues, respectively, in low-dose samples (0.3 μg/L), and 65, 32, and 122 for whole fish, edible, 

and non-edible fish tissues, respectively, in high-dose samples (3.0 μg/L). BCF values less than 

1000 do not trigger criteria for further evaluation of bioaccumulative compounds [64 Fed. Reg. 

60194-60204 (November 4, 1999)]. 

3.1.5. Environmental Degradates 

 The transformation products resulting from the environmental degradation processes of 

indaziflam are: triazine-indanone, indaziflam-carboxylic acid, indaziflam-hydroxyethyl, 

indaziflam-olefin, diaminotriazine, and dihydroaminotriazine; all of which were identified as 

major degradates (Table 2.1). Peak detections of these compounds were identified at a 

maximum of 17.4% (90 DAT), 21.7% (30 DAT), 20.8% (study termination, 3 DAT), 53.9% 

(study termination, 3 DAT), 39% (study termination, 368 DAT), and 25.7% (30 DAT) of the 

applied, respectively. These degradates are moderately persistent to persistent. Major 

degradates that are structurally similar to the parent include triazine-indanone, indaziflamcarboxylic acid, indaziflam-hydroxyethyl, and indaziflam-olefin. Chemical structures, chemical 

names, and other pertinent information on these degradation products, as well as data on minor 

degradation products are included in Appendix A. 

 The main degradation pathway of indaziflam appears to be via oxidation of the indanyl 

moiety to form indaziflam-triazine indanone and indaziflam-carboxylic acid. Indaziflam, 

triazine indanone and indaziflam-carboxylic acid are cleaved at the N bridge to form 

diaminotriazine from the triazine moiety and unidentified minor compounds from the indanyl 

moiety. Residues are ultimately converted to bound residues and CO2. The maximum amounts 

of these degradation products observed in hydrolysis, aerobic aquatic metabolism, anaerobic 
Page 17 of 131 

aquatic metabolism, soil column leaching, and aqueous photolysis studies are summarized in 

Table 2.1. 

 Chemical structures for minor degradation products were not reported in any study and 

the percent of formation was frequently below 1%, except in a few cases where percent of 

applied radiation reached 2 to 4% (ROI2; MRID 47443214; Reg #1; MRID 47443208). Further, 

unidentified products were observed at 1 to 4 % of the applied radiation in aerobic aquatic 

systems (MRID 47443217). 

 A meeting held by OPP’s Residues of Concern Knowledgebase Subcommittee (ROCKS) 

on November 19, 2009 concluded that based on the uncertainty due to lack of toxicity data on the 

major degradates (triazine-indanone, indaziflam-carboxylic acid, diaminotriazine, indaziflamhydroxyethyl, and indaziflam-olefin), all residues that maintain the parent “dual-ring” structure, 

and diaminotriazine must be included as residues of concern for the drinking water exposure 

assessment (D371659). Environmental half-lives were recalculated based on the conclusions 

from the ROCKS. Therefore, a total toxic residues approach was used for this assessment for 

aquatic exposure to evaluate the potential exposure to the residues of indaziflam that retain the 

dual ring structure, i.e., indaziflam, triazine-indanone, indaziflam-carboxylic acid, indaziflamhydroxyethyl, and indaziflam-olefin. Exposure to diaminotriazine is calculated separately since 

it is expected to have a distinct mode of action and toxicological endpoint compared to 

indaziflam. Structural analysis suggested that an assumption of additivity for the similarly 

structured residues is reasonable (USEPA, 2006). This modeling strategy requires an assumption 

that all residues of concern have similar physical, chemical, and partitioning characteristics. The 

formation of persistent, toxic degradation products is expected to extend the residual effects of 

the parent. Therefore, methodology outlined in the “White Paper on Methods for Assessing 

Ecological Risks of Pesticides with Persistent, Bioaccumulative and Toxic Characteristics” 

presented to the FIFRA Scientific Advisor Panel, in October, 2008, was followed to calculate 

total toxic residues of concern (parent plus triazine-indanone, indaziflam-carboxylic acid, 

indaziflam-hydroxyethyl, and indaziflam-olefin) (USEPA, 2008b). Application rates for 

indaziflam were used to represent the total mass loading of pesticide and its degradation product. 

This modeling approach does not consider temporal occurrence of specific degradation products. 

 Using the methodology outlined in the PBT SAP white paper, we assume that indaziflam 

+ similarly structured residues of concern have similar physical, chemical, and portioning 

characteristics. As a conservative assumption, we used the mean Freundlich adsorption 

coefficient (Kf) of the most mobile degradate (i.e., indaziflam-carboxylic acid). This is a 

conservative assumption. In reality, indaziflam and the various degradates will be transported in 

the environment at varying rates. 

Diaminotriazine was modeled separately for drinking water exposure estimates as there is 

a separate toxicological endpoint. The half-lives were based on a supplemental aerobic soil 

metabolism study (MRID 47443214). The modeling assumed 100% conversion of indaziflam to 

diaminotriazine, therefore, application rates for diaminotriazine were the same as the equivalent 

indaziflam applications adjusted by the molecular weight ratio (157/301). This is a conservative 

assumption, but reasonable as diaminotriazine is the terminal degradate in the proposed 

degradation pathway.

3.2. Drinking Water Exposure Modeling 

Estimated drinking water concentrations (EDWCs) were generated using OPP’s standard 

suite of models. The proposed use patterns for perennial tree and vine crops (citrus, stone fruit, 

pome fruit, grapes, tree nuts, pistachios, olives), pre emergent and post emergent weed control on 

turf (golf courses, athletic fields, parks, recreation areas, and sod farms), home lawns, 

ornamentals and hardscapes (sidewalks, driveways), commercial forests, Christmas tree farms, 

and other non-crop areas (railroad and rail yards, managed roadsides, fence rows, utilities, other 

industrial, municipal, and government sites) were assessed. Drinking water exposure 

concentrations were determined for indaziflam + similarly structured degradates (triazine 

indanone, indaziflam-carboxylic acid, indaziflam-olefin, and indaziflam-hydroxyethyl), and the 

degradate diaminotriazine. 

3.2.1. Models 

 PRZM (v3.12.2, 5/12/2005) and EXAMS (v2.98.4.6, 4/25/2005) are simulation models 

coupled with the input shell PE (v5.0, 11/15/2006) to generate daily exposures and 1-in-10 year 

EDWCs of indaziflam residues that may occur in surface water bodies adjacent to application 

sites receiving indaziflam through runoff and spray drift. The PRZM model simulates pesticide 

movement and transformation on and across the agricultural field resulting from crop 

applications. The EXAMS model simulates pesticide loading via runoff, erosion, and spray drift 

assuming a standard watershed of 172.8 ha that drains into an adjacent standard drinking water 

index reservoir of 5.26 ha, and an average depth of 2.74 m. A more detailed description of the 

index reservoir watershed can be found in Jones et al., 1998. The coupled PRZM/EXAMS 

model and users manuals may be downloaded from the U.S. Environmental Protection Agency 

(EPA) Water Models web-page (USEPA, 2006). Percent Cropped Area (PCA) adjustment 

factors account for the maximum area within a watershed that may be planted with the modeled 

crop. PCAs are applied to concentrations predicted by PRZM/EXAMS. 

 Screening Concentration in Ground Water (SCI-GROW v2.3, Jul. 29, 2003) is a 

regression model used as a screening tool to estimate pesticide concentrations found in ground 

water used as drinking water. SCI-GROW was developed by fitting a linear model to ground 

water concentrations with the Relative Index of Leaching Potential (RILP) as the independent 

variable. Ground water concentrations were based on measurements of 90-day average high 

concentrations in Prospective Ground Water studies. The RILP is a function of aerobic soil 

metabolism and the soil-water partition coefficient (Koc). The output of SCI-GROW represents 

the concentrations of indaziflam residue that might be expected in shallow unconfined aquifers 

under sandy soils that may serve as a drinking water source. These conditions represent the 

ground water most vulnerable to pesticide contamination. The SCI-GROW model and user’s 

manual may also be downloaded from the EPA Water Models web-page (USEPA, 2006). 

3.2.2. Input Parameters 

Currently approved PRZM scenarios were used in modeling. Multiple scenarios were 

modeled for each use, where available, and final scenario selection was based on what was likely 
Page 19 of 131 

to be the most vulnerable scenario. Application methods and rates were obtained from the 

proposed labels. Application timing of indaziflam is related to various pest pressures (e.g., weed 

germination). The label states that “for best results” apply indaziflam prior to weed germination. 

This is a recommended application timing, and is not an enforceable application practice; there 

are no prohibitions on year-round applications of indaziflam. Therefore, for the purposes of this 

assessment, initial application dates were selected in order to reflect labeled crop timing for 

applications, weather file data, and pest pressure information provided by the United States 

Department of Agriculture and extension agents making sure applications were consistent with 

the crop timing set by the model scenarios. All modeling was completed in accordance with the 

proposed labels as they were submitted in the application for registration. The Lawn 3FL 

product labels were refined base on email communications with Bayer CropScience through the 

Risk Manager (Erik Kraft, Registration Division) on November 6, 2009. 

Indaziflam chemical specific and model input values were chosen in accordance with 

current input parameter guidance (USEPA, 2009). Degradates of indaziflam that maintain the 

dual ring structure were found by HED to be of unknown toxicity, therefore were included in this 

exposure assessment. Total toxic residue half-lives were calculated for parent and four 

metabolites (triazine indanone, indaziflam-carboxylic acid, indaziflam-hydroxyethyl, and 

indaziflam-olefin) based on the conclusions of the ROCKS report (D371659). Calculated total 

toxic residue half-lives are listed in Table 3.2, and the upper 90th percentile confidence on the 

mean of the total toxic residue half-lives, used in the drinking water exposure modeling, are 

presented in Table 3.4. 

The degradation studies were characterized by large amount of un-extracted and 

uncharacterized material; thus there is considerable uncertainty regarding the degradation of 

indaziflam residues in the environment. To characterize this uncertainty, model simulations 

were completed using two sets of environmental half-lives: 1) high-end conservative estimates 

which were completed using half-lives that included un-extracted residues, and 2) the low-end 

estimates based on half-lives that excluded un-extracted residues. Model results using the upperbound conservative half-lives are presented in this assessment; the range between the lower 

bound and the upper bound was not that great (no more than 26% difference1

), therefore only the 

upper bound estimates are listed in Tables 3.7-3.8 and 3.12-3.13, and the lower-bound estimates 

are included in Appendix B. 

 Standard default percent cropped areas (PCA) were used for all agricultural uses as 

estimates of the extent of watershed on which crops is grown (Effland et al., 1999); the default 

agricultural PCA of 0.87 was applied. Drinking water PCAs have not been developed for the 

proposed non-agricultural uses of indaziflam, with the exception of the higher tier refinement for 

the golf course adjustment factor (i.e., PCA of 1.0 was applied for all non-agricultural uses). 

Actual fractions of cropped areas could be less in some areas of the country.

 With the exception of the hardscape model estimates. The difference between the upper bound and lower bound 

was as much as 39%. 
Page 20 of 131 

3.2.3. Scenario Selection 

 For surface water, eight currently available scenarios and one provisional scenario 

(FLimpervious.txt) were used to represent high exposure sites for all uses of indaziflam. Table 

3.4 lists the scenarios used to model each use. These nine sites represent 172.2 hectare 

watersheds draining into a 5.26 hectare lake, 2.74 m deep. This watershed, commonly known as 

the index reservoir, was developed to represent a watershed that was more vulnerable than most 

watersheds to pesticide contamination. It represents a real drinking water reservoir in Illinois, 

Shipman City Lake. The geometry for the index reservoir is used with local weather and soils to 

represent vulnerable watersheds for different crops in different regions of the country. A 

detailed description of the index reservoir can be found in the guidance for using the index 

reservoir (U.S. Environmental Protection Agency, 2000). 

 For the hardscape use, a provisional scenario (FLimpervious.txt) was used to represent 

high exposure sites resulting from applications directly to impervious surfaces (e.g., patio, 

sidewalk and driveway cracks, on paths and gravel areas, along fence lines). The Florida 

impervious scenario was modified from an existing California impervious scenario 

(CAimperviousRLF.txt) developed for the endangered species assessments in California. The 

provisional scenario represents a conservative high-end exposure resulting from applications of 

indaziflam to hardscapes in West Palm Beach. Florida was chosen, specifically West Palm 

Beach, to represent conservative exposure estimates because the precipitation is on average 

greater in this region of the country compared to other areas (e.g., Fresno, California). The 

scenario uses weather data from West Palm Beach, FL (W12844). This scenario is included in 

Appendix C, along with brief descriptions of each scenario used for estimating drinking water 

exposure in surface water. 

3.2.4. Methods for Determining Parent (Indaziflam) Concentrations

Table 3.4 lists applicable model scenarios, proposed label application rates, and 

management practices. Chemical specific input parameters for the PRZM/EXAMS and SCIGROW models are listed in Table 3.5. Table 3.6 lists input parameters for SCI-GROW. 

Conservative estimates of exposure for indaziflam + similarly structured residues were 

completed using the mean Freundlich adsorption coefficient (Kf) for the most mobile degradate 

(i.e., the lowest Kf); this was used as a conservative assumption for the mobility of the 

compound. For the hardscape scenario, the Kf was set to zero (0) as there is nothing for the 

chemical to bind to on an impervious surface (e.g., pavement or concrete). Using a low 

adsorption coefficient (e.g., Kf = 0.84, the mean Kf of most mobile degradate) forces some 

amount of infiltration, thus underestimating the concentration of indaziflam in runoff. Therefore, 

the Kf for indaziflam + similarly structured resides was set to zero for modeling estimates 

resulting from applications to hardscapes. Although these estimates are conservative, it is 

important to note that this approach may over estimate surface water concentrations as there is 

some amount of binding that will occur in the reservoir. 

 

The surface water model estimates for hardscapes, are conservative estimates of drinking 

water concentrations since it assumes that 100% of the 172 ha watershed is treated with 
Page 21 of 131 

indaziflam. Actual use patterns may differ from modeled uses (e.g., hardscapes may be spot 

treated); however, these estimates represent a conservative estimate of concentrations in drinking 

water, actual concentrations may be lower than these estimates for hardscape uses, thus are 

protective of use patterns with lower application rates or reductions in areas that receive 

treatment. Additionally, the hardscapes scenario assumes that the entire watershed is impervious 

and simultaneously treated, which is a highly conservative assumption. Exposure estimates for 

hardscape applications are characterized in further detail in Section 4.0.

3.2.4.1. Model Results: Surface Water Concentration of Indaziflam + Similarly 

Structured Residues

 All current and proposed use patterns were modeled for surface water and ground water 

exposure estimates, as described above. Estimated drinking water concentrations (EDWCs) of 

indaziflam + similarly structure residues in surface water for the modeled maximum use patterns 

are listed below in Table 3.7 (along with corresponding PCA factors). Acute EDWCs for parent 

+ similarly structure residues + un-extracted residues in surface water ranged from 0.7 to 48 

ug·L-1. A chronic concentration ranging from 0.6 to 14.0 μg·L-1 and a 30-year average 

concentration ranging from 0.2 to 2.3 μg·L-1.Additional EDWCs excluding un-extracted residues 

in the calculations of half-lives are listed in Appendix C 

 These concentrations reflect maximum use rates for all uses on the proposed labels, 

except for other non-crop areas which are represented by the ornamentals and hardscapes 

simulations, as these uses will likely be similar to the proposed other non-crop area use. Model 

outputs for surface water estimates are included in Appendix D.

 Bold values indicate maximum drinking water concentrations in surface water. Estimates for hardscapes are a conservative high-end estimate, 

which assumes 100% of the impervious is treated with indaziflam. These estimates are protective of scenarios where a lower percentage of area 

is treated with indaziflam.

surfaces.

3.2.4.2. Model Results: Ground Water Concentrations of Indaziflam + Similarly 

Structured Residues 

 

SCI-GROW was used to estimate ground water concentrations resulting from the use of 

indaziflam. SCI-GROW is based on the fate properties of the pesticide (i.e., the median Koc and 

median aerobic soil metabolism half-life), the application rate, and the concentration data from 

13 small-scale ground water monitoring studies. In order to generate conservative estimates of 

exposure for indaziflam + similarly structured residues, the median Freundlich organic carbon 

partitioning coefficient (Kfoc) for the degradate with the highest mobility (indaziflam-carboxylic 

acid) was used as a conservative input. 

Model simulations were completed using two sets of environmental half-lives: 1) highend conservative estimates which were completed using half-lives that included un-extracted 

residues, and 2) the low-end estimates based on half-lives that excluded un-extracted residues. 

Results listed in Table 3.8 reflect the bounds of the drinking water estimates. 

The maximum concentration in ground water for indaziflam + similarly structured 

residues, estimated using SCI-GROW, is approximately 1.57 μg·L-1 resulting from applications 

to agricultural crops (Citrus, Stone Fruit, Pome Fruit, Grapes, Tree Nuts, Pistachios, Olives). 

Table 3.8 lists the EDWCs for ground water from five different use patterns, representing food, 

turf, home/residential lawn, ornamentals and hardscapes, and forestry uses. Model outputs for 

ground water estimates are included in Appendix E.

3.2.5. Methods for Determining Diaminotriazine + Dihydroaminotriazine 

Concentrations 

 All processes that describe indaziflam degradation in the submitted data show that 

diaminotriazine is a terminal degradate in the metabolism pathway. Therefore, it is reasonable to 

assume that diaminotriazine can be simulated with the same scenarios as indaziflam and with the 

same molar application rate as indaziflam. Degradation studies, using diaminotriazine as the 

starting material, showed that dihydroaminotriazine (ROI1) forms at significant amounts 

(maximum percentage of applied radiation was 21%, 58 DAT), therefore it was included in a 

total toxic residue approach for exposure in drinking water (MRID 47443214). 
Page 25 of 131 

 Application rates for these scenarios are the same as the equivalent indaziflam 

applications except that they were adjusted by the molecular weight ratio (157/301). Application 

dates, and application methods are the same as the parent indaziflam. Chemical input parameters 

are summarized in Tables 3.9 for surface water and Table 3.11 for ground water. 

As supported by available data, the fundamental assumption here is that all indaziflam 

degrades to diaminotriazine at some point. However, it is not known when the formation of 

diaminotriazine will occur with respect to the time of application of indaziflam to a field. It is 

not likely (as supported by registrant studies) that this transformation would occur rapidly (e.g., 

within days). Rapid formation of diaminotriazine from indaziflam promotes high acute 

estimates because of the greater availability of diaminotriazine at one time; whereas slower 

formation would dampen peak diaminotriazine formation, but have less impact on long-term 

average concentration. Thus, acute estimates were derived assuming rapid formation of 

diaminotriazine and are likely conservative. Notably, conservative assumptions were made 

during the calculations of both diaminotriazine and its parent indaziflam, which would be 

contradictory if both assumptions held simultaneously. For example, in the calculation of 

diaminotriazine EDWCs, it was assumed that rapid transformation of indaziflam to 

diaminotriazine occurred; whereas in the calculation for indaziflam, it was assumed that 

indaziflam degraded slowly. Clearly both cases cannot occur, but it is uncertain which case is 

the actual case. Thus both cases are presented in this assessment with the understanding that the 

concentrations derived for diaminotriazine and indaziflam residues are not intended to represent 

concurrent exposure concentrations. 

Methods for modeling applications of diaminotriazine to hardscapes were described 

above in Section 3.2.4.

 Initial application was selected as March 1, with a second application 265 days later, as permitted on the proposed label (a late fall and an early 

spring application within a 12 month period, limitations of PRZM prohibit applications across the calendar year. 4

 Label permits two applications per year (a summer application followed by winter, or winter followed by spring, or fall followed by spring, or 

spring followed by fall). The label only permits a maximum of 473 lbs of product/A per 12 months (0.1004 lb a.i./A/yr). Initial application rate 

was chosen to coincide with peak rainfall (based on a 30-year average of rainfall events), while following label application instructions. 5

 Florida impervious scenario, currently a provisional scenario, is included in Appendix C. 6

 NC apples scenario was selected as the most vulnerable scenario to represent forestry uses since crop profile for apple orchard is similar to a 

profile for a commercial forest.

Dihydroaminotriazine (ROI1) 

 Results for surface water concentrations of diaminotriazine + ROI1 are given in Table 

3.12 for the PRZM/EXAMS surface water simulations. As with the parent, the highest surface 

water concentrations resulted from the use on hardscapes (Florida Impervious scenario) with 

acute concentrations of 19 μg·L-1, a chronic concentration of 6.0 μg·L-1 and a 30-year average 

concentration of 0.8 μg·L-1. Model outputs for surface water estimates are included in Appendix

3.2.5.2. Model Results: Ground Water Concentrations of Diaminotriazine 

Results for ground water concentrations of diaminotriazine are provided in Table 3.13

for SCI-GROW simulations. The highest concentration estimated in ground water using 

SCIGROW was from the food use (citrus, stone fruit, tree nuts, and vine crops), 1.07 μg·L-1. 

Table 3.13 lists the EDWCs for ground water from five different use patterns, representing food, 

turf, lawn, ornamentals and hardscapes, and forestry uses. Model outputs for ground water 

estimates are included in Appendix E. 

Model simulations were completed using two sets of environmental half-lives: 1) highend conservative estimates which were completed using half-lives that included un-extracted 

residues, and 2) the low-end estimates based on half-lives that excluded un-extracted residues. 

Results listed in Table 3.13 reflect the bounds of the drinking water estimates.

3.3. Monitoring Data

 Indaziflam is a new chemical, therefore there are no monitoring data currently available. 

3.4. Drinking Water Treatment Effects

 No specific information on the effects of drinking water treatment are available for 

indaziflam or any of its degradates. 

3.5. Uncertainties and Data Gaps

Prominent uncertainties in this assessment include the characterization and quantification 

of the degradation of indaziflam and its transformation products. There is also uncertainty 

associated with the formation of the degradate diaminotriazine (which was modeled separately). 

Degradation quantification was confounded by large amounts of un-extracted material that was 

reported in the degradation studies conducted with soil for both indaziflam and diaminotriazine. 

The amount of un-extracted and uncharacterized material hindered accurate estimation of 

degradation rates. Another uncertainty is the formation rate of diaminotriazine. Although 

proposed pathways for degradation (included with submitted studies), suggest that 

diaminotriazine is formed during nearly all degradation processes, and it was increasing in 

concentration at the termination of those studies where it was detected. These uncertainties have 

led to the conservative exposure assessment described here. 

An additional source of uncertainty is the mobility of indaziflam and its degradates. We 

assumed, based on the methodology outlined in the PBT SAP white paper (USEPA, 2008), that 

indaziflam + similarly structured residues have similar chemical, physical, and portioning 

characteristics. In order to generate conservative estimates, we assumed that indaziflam + 

similarly structure residues was as mobile together as the most mobile degradate (indaziflamcarboxylic acid). We know that indaziflam degradates are more mobile than the parent, therefore 

this is a reasonably conservative assumption for the purposes of generating EDWCs. However, 

it is not known when the formation of indaziflam degradates will occur with respect to the time 

of application of indaziflam to a field. It is not likely (as supported by registrant studies) that this 
Page 30 of 131 

transformation would occur rapidly. Therefore, if the formation of these degradates is slow, 

concentrations in drinking water may be lower. 

There is uncertainty regarding the leaching potential of indaziflam and its degradates. In 

the field studies, the limit of detection (LOD) for parent indaziflam and its transformation 

products was 0.3 ng a.i./g, and the limit of quantitation (LOQ) was 1.5 ng a.i./g for all studies. 

Substantial concentrations of indaziflam and its major transformation products were reported 

between the LOD and the LOQ in all field studies. Detections below the LOQ are not accurately 

characterized because of the gap between the LOD and the LOQ; therefore, the analytical 

method may have been too insensitive to accurately describe the leaching potential of indaziflam 

and its major transformation products. Replicate values below the LOQ were assumed at 

1⁄2(LOQ + LOD) for calculations of dissipation half-lives. 

There is also uncertainty associated with the ability of the aquatic exposure modeling to 

simulate exposures in drinking water as well as in the selection of input parameters. In this 

regard, one of the potentially important parameters that can impact concentration estimates is the 

selection of appropriate application dates. Although the pesticide application dates were selected 

to be most appropriate with considerations for label restrictions, recommendations, and 

simulated cropping dates, variability nevertheless results because the time span that a pesticide 

may likely be applied may be large and the actual application dates are unknown. Such 

variability is caused by the temporal proximity of a pesticide application to rain events. As with 

all model estimates, the values presented here should not be viewed as precise estimates. 

 The modeling assessment for agricultural uses relied on maximum use patterns and a 

national default PCA (0.87). There is no PCA for turf, forestry, or residential uses so a PCA of 1 

was applied to these uses. A PCA of 1 for turf and non-ag uses (residential lawns, hardscapes, 

forestry, and other non-crop areas) assumes that the entire watershed is in that modeled use (e.g., 

turf) and is simultaneously treated, which is a conservative assumption. To the extent that actual 

use patterns are less than the labeled maximums and the location-specific PCAs are less than 

assumed in this assessment, actual environmental exposures could be lower. 

There is additional uncertainty associated with the modeling of exposure resulting from 

applications to impervious surfaces (hardscape use). A number of assumptions were employed 

in the modeling of these uses and may not represent actual use patterns (e.g., hardscapes may be 

spot treated, not all areas in a watershed are simultaneously treated). To the extent that actual 

use patterns differ from modeling assumptions, actual environmental concentrations in drinking 

water could be lower. However, there is the uncertainty regarding the cumulative exposure 

resulting from all residential uses of indaziflam (hardscapes, ornamentals, and home lawns). 

Conceptually, these use patterns could occur at the same time, thus exposure estimates may be 

higher than previously estimated if all residential uses are evaluated together. 

4. Characterization of Applications to Hardscapes 

 Exposure estimates completed for the hardscape uses of indaziflam (e.g., driveways, 

patios, sidewalks, fence lines) conservatively assumed 100% of the watershed was impervious 

and received applications of indaziflam. This is likely an overly conservative estimate of 
Page 31 of 131 

exposure. Actual use patterns may vary from the modeled estimates. Fundamentally, less than 

100% of the watershed of an urban/suburban system will be impervious (assuming a typical lot 

equals approximately 1⁄4 of an acre, 50% of which is pervious surfaces, and 50% impervious); 

therefore less than 100% of the 10 ha simulated watershed will be treated with indaziflam. The 

assumption concerning a 1⁄4 acre residential lot size, with approximate dimensions of impervious 

surface equal to 750 square foot driveway, a 250 square foot sidewalk, and a 300 square foot 

deck/patio was adopted from the Chesapeake Bay Endangered Species Assessment (USEPA, 

2006b), which was further refined in the Pesticide Effects Determination for the Risks of 

Carbaryl Use to the Federally-Listed California Red Legged Frog (USEPA, 2007). The 

approach we used to characterize the exposure estimates resulting from applications of 

indaziflam on hardscapes was the similar to these two assessments, however the dimensions of 

the watershed were adjusted to represent the index reservoir, thus the number of lots in the 

watershed increased. 

 Further, there is an assumed area in the index reservoir watershed that would not be 

planted (e.g., turf or other ornamentals) and would not have a residential lot (e.g., stream 

network of rivers, streams, drainage ditches, etc.). The assumed total area of the stream network 

in the index reservoir watershed consists of 2200 m2

 of perennial streams and 3800 m2 of 

ephemeral streams, for a combined land area of 6000 m2 (USEPA, 1999). This area is subtracted 

from the total watershed area in the calculation of the number of 1⁄4 acre lots in the watershed. 

It was also assumed that the 300 square foot deck could be a 300 square foot patio, 

resulting in 12% of a 1⁄4 acre lot in an urban/suburban watershed that would be covered with 

impervious surfaces. The index reservoir watershed is set to a 172.2 ha area, some of which 

would not receive pesticide applications area (i.e., waterways, drainage ditches, etc.). There 

could conceivably be approximately 2,186 lots in a 172.2 ha watershed (using the same 

assumptions of corner lot and mid-lot spacing provided in Appendix F); therefore there is 

approximately 15% of the 172.2 ha watershed would be impervious surface that could potentially 

receive treatment of indaziflam ([1/4 acre lot (10,890 ft2) x 12% impervious surface x 2186 lots / 

18,470,871 ft2

 x 100 = 15.0%). Additional detail and rationale for the methodology and 

calculations of impervious surfaces, lot size, and number of lots in the simulated watershed is 

included in Appendix F. The break down of the different landuses in the simulated watershed is 

listed below. 

Total Watershed Area = 172.2 ha (18,535,453 ft2

) 

50% pervious area 

 Stream network = 4% (741,418 ft2

) 

50% impervious area (roadways, driveways, sidewalks, patio, house) 

 Impervious Area (potentially treated; driveways, sidewalks, patio) = 15% 

 (2,780,318 ft2

) 

 Impervious Untreated (roadways, and houses) = 35% (6,487,408 ft2) 

 The conceptual model for applications to hardscape has two conservative assumptions. 

First, it assumes that indaziflam could be applied to all of the 15% impervious surfaces on a 1⁄4 

acre lot. Second, it assumes that all hardscapes are treated simultaneously. Additional 

refinements could include variation in the percentages of impervious surfaces that received 
Page 32 of 131 

treatment in the 1⁄4 acre lot to simulate differences in potential use practices, or use areas. The 

following algorithm was used to calculate the aquatic EDWCs for hardscape applications: 

Hardscape EDWC = [(impervious EDWC) x (% impervious 

surface treated)] 

 Adjusted drinking water exposure estimates resulting from applications of indaziflam + 

similarly structured residues on hardscapes are list in Table 3.14, and applications of 

diaminotriazine + ROI1 are listed in Table 3.15.

5. CONCLUSIONS AND EXPOSURE CHARACTERIZATION 

 Drinking water exposure estimates based on total toxic residues for indaziflam uses on 

perennial tree and vine crops, athletic turf, home lawns, ornamentals, hardscapes, and 

commercial forests are represented by maximum use rates on the proposed labels. Separate 

drinking water exposure estimates were generated for the degradate diaminotriazine as it was 

determined to be of toxicological concern and has a separate endpoint. The environmental fate 

data used to generate these estimates are generally good, with a few large uncertainties. The 

degradation studies were characterized by large amounts of un-extracted and uncharacterized 

residues, thus there is considerable uncertainty regarding the degradation of indaziflam in soil 

and aquatic systems. To address this uncertainty, model estimates were completed using two 

sets of aerobic metabolism half-lives for indaziflam + degradates, and diaminotriazine; 1) parentonly + degradates, and 2) parent + un-extracted residues + degradates. The model simulation 

results are bounded by the conservative upper-bound estimates using parent + un-extracted 

residues + degradates, and the lower-bound parent-only + degradates half-lives. 

 The modeling results using the more conservative (longer) half-lives may over estimate 

concentrations of indaziflam in drinking water. However, the aerobic soil and aerobic aquatic 

metabolism studies were characterized by large amounts of un-extracted residues, and the 

extraction methods were not stringent enough (e.g., multiple solvents were not employed for the 
Page 33 of 131 

extractions). Therefore, it is uncertain whether the un-extracted residues were parent residues, 

metabolite residues, or in fact bound residues. The more conservative half-lives used in the 

upper-bound of the modeling results were presented to capture these uncertainties. Additional 

studies with multiple extraction methods would help to reduce the uncertainty of the 

environmental half-lives. 

 Acute EDWCs for indaziflam + similarly structured residues ranged from 0.7 to 48 ppb 

for surface water and from 1.09 to 1.57 ppb for ground water1

. Chronic and cancer EDWCs 

ranged from 0.6 to 14.0 ppb and from 0.2 to 2.3 ppb, respectively, for surface water. Acute 

EDWCs for diaminotriazine ranged from 0.3 to 19 ppb for surface water and from 0.73 to 1.07 

ppb for ground water. Chronic and cancer EDWCs for diaminotriazine ranged from 0.4 to 6.0 

ppb and from 0.2 to 1.2 ppb, respectively, for surface water. 

 The surface water model estimates for hardscapes, turf, and other non-ag uses is a 

conservative estimate of drinking water concentrations since it assumes that 100% of the 172 ha 

watershed is treated with indaziflam. Actual use patterns may differ from modeled uses (e.g., 

hardscapes may be spot treated); however, these estimates represent a conservative estimate of 

concentrations in drinking water, actual concentrations may be lower than these estimates for 

hardscape uses, thus are protective of use patterns with lower application rates or reduced areas 

that would receive treatment. Additionally, the hardscapes scenario assumes that the entire 

watershed is impervious and simultaneously treated, which is a conservative assumption. 

 Further, we expect the degradates of indaziflam, particularly diaminotriazine to leach to 

ground water and impact ground water quality. Diaminotriazine was detected at deeper depths in 

the field studies compared to the parent and other degradates; it is persistent and it is classified as 

highly mobile. Based on the fate properties and field results for diaminotriazine, as well as 

surrogate information on other triazine herbicides with a structurally similar degradate, we 

estimate this compound will be transported to ground water.

 The field used to represent citrus production is in Florida, located in Collier or Hendry 

Counties in Southwest Florida. According to the 1997 Census of Agriculture, Florida is the 

major producer of citrus (oranges) for the juice market and among the highest for the fresh 

market. The field has Wabasso fine sand, which is a sandy, siliceous, hyperthermic Alfic 

Alaquods. These soils are often used for citrus production and truck crops. The soil is extensive 

in Florida. Wabasso fine sand is a Hydrologic Group D soil. The weather data is from weather 

station W12844 in West Palm Beach, Florida. 

 The field used to represent apple production is in North Carolina, and is located in 

Henderson County, in Western North Carolina. According to the 1997 Census of Agriculture, 

North Carolina is among the major producers of apples (7th to 8th overall) in the U.S., and is one 

of the southern most production areas. There are four primary apple production areas in western 

North Carolina, all long-term perennial regions, grown on a variety of soils, in different climate 

regions. Henderson County produces between 60 to 70 percent of the apple crop. The field has 

Hayesville loam, which is a fine, kaolinitic, mesic, Typic Kanhapludults. Hayesville loam is a 

Hydrologic Group C soil. The weather data is from weather station W03812 in Ashville, North 

Carolina. 

For the stone fruit use, a field representing blackberry production in Marion County, 

Oregon was used. Blackberries are a bramble fruit, known as aggregated drupe fruit (stone fruit) 

composed of small, individual drupes. According to the 1997 Census of Agriculture, Oregon is 

the leading state in the production of blackberries in the U.S. Marion County leads Oregon in 
Page 50 of 131 

acres planted in 1997. The field has Woodburn silt loam, which is a fine-silty mixed, 

superactive, mesic Aquultic Agrixerolls. The series is used to produce berries, orchards, cannery 

crops, grain, hay, and pasture. The series is extensive in the Willamette Valley, where the 

scenario is located. Woodburn silt loam is a Hydrologic Group C soil. The weather data is from 

weather station W24232 in Salem, Oregon. 

The field used to represent tree nut production is in Georgia is located in Mitchell or 

Dougherty County in Southwest Georgia (MLRA133) and the weather station representing the 

orchard’s weather is located in Tallahassee, FL (W93805). The scenario was developed to 

represent pecan production. Pecans are grown throughout the southwestern part of the state. 

Georgia and Texas generally compete from year to tear for status as the top U.S. producer. Trees 

are very large, growing up to 100 feet tall and living 80 or more years, although production 

declines as the trees reach the end of its life span. The field has Williston loamy fine sand, 

which is a fine, mixed, superactive, hyperthermic Typic Hapludalfs. Williston loamy fine sand is 

a Hydrologic Group C soil. 

Indazilfam use on grapes was represented using a vineyard in New York located in 

Chautauqua County in Southwest New York along Lake Erie (MLRA100/101) with the weather 

station representing the vineyard’s weather located in Erie, PA (W14860). Grapes are grown 

throughout the state, but are concentrated in the western part of the state where the macroclimate 

is best suited for grape production. New York is among the leading Eastern U.S. state in both 

wine and table grape production. Chautauqua County has the highest acreage in the state and 

New York remains the 3rd or 4th highest production state in the U.S. The soil selected to simulate 

the vineyard is a Lordstown channery silt loam. Lordstown channey silt loam is a coarse-loamy, 

mixed, active, mesic Typic Dystrudepts. 

 Indaziflam use on olives was represented using a scenario intended to represent olive 

production in California’s San Joaquin Valley, primarily in Tulare, Madera, Fresno, and Kings 

Counties. Over 99% of the olives grown in the United States are grown in California with 

approximately 35,300 bearing acres of olives (USDA, 1999). Nearly 65% of California’s olive 

acreage is located in the San Joaquin Valley, primarily in Tulare County (53% of the total) 

(USDA, 1999). Moreover, based on 2005 California Pesticide Usage Reporting (CalPIP, 2006), 

approximately 80% of pesticides used on California olives (by pounds of chemical) were applied 

in San Joaquin Valley. The Porterville series is the third most common soil found where olives 

are grown, and was used to represent this field. It is a fine, smectitic, thermic Aridic 

Haploxererts. Porterville is a Hydrologic Group D soil. The weather data is from weather 

station W93193 in Fresno, California. 

 The field used to represent turf grass in Florida is located in Osceola County within 

MLRA 155, although turf grasses (golf courses, sod farms, etc.) are located throughout the state. 

This turf scenario is considered to be essentially generic, with no distinction made between sod 

farms, golf course fairways, greens and tees, or residential lawns. To develop a turf scenario the 

soil was modified by adding a 2 cm thick layer of thatch on top of the soil profile. The thatch 

layer has the following properties: bulk density = 0.37; field capacity = 0.47; wilting point = 

0.27; organic carbon = 7.5%. Curve numbers were selected based on good condition open space 

areas as specified in TR-55, that is for hydrologic soil groups C. A 2 cm layer of thatch is typical 
Page 51 of 131 

for golf course fairways, but is probably thicker than average for golf course greens. The soil 

selected to simulate turf grass is an Adamsville sand, a hyperthermic, uncoated Aquic 

Quartzipsamment. Adamsville sand ranges from a Hydrologic Group A soil to a Hydrologic 

Group C soil, depending on the water table. For the purpose of this modeling, EFED used the 

curve numbers from the PIC of the Adamsville sand as a Group C soil. The weather data is from 

weather station W12834 in Daytona Beach, Florida. 

 The residential scenario is intended to be used as a surrogate for all urban/suburban home 

and residential uses in the San Francisco Bay area of California. Crop parameters have been 

chosen to reflect residential turf areas, primarily lawns, within the urban area. Residential Lawns 

are irrigated year round, even during the wet season. Tierra soils were chosen to represent 

residential areas. Tierra is a Hydrologic Group D soil which account for approximately 40% of 

urban soils in drainage, these soils are fine alluvial deposits. The weather data is from weather 

station W23234 in San Fransisco, CA. 

 Indaziflam use on forestry was represented by a surrogate scenario, North Carolina 

Apples (NCapplesSTD.txt). This scenario is described above. It was selected as a surrogate to 

represent a vulnerable scenario for forestry applications due to the precipitation that it receives, 

and the soil types. It is reasonable to use the apple scenario as a surrogate for forestry uses since 

the apple tree is physiologically similar to commercial forestry trees. 

 For the hardscape use, a provisional scenario (FLimpervious.txt) was used to represent 

high exposure sites resulting from applications directly to impervious surfaces (e.g., patio, 

sidewalk and driveway cracks, on paths and gravel areas, along fence lines). The Florida 

impervious scenario was modified from an existing California impervious scenario 

(CAimperviousRLF.txt) developed for the endangered species assessments in California. The 

provisional scenario represents a conservative high-end exposure resulting from applications of 

indaziflam to hardscapes in West Palm Beach. Florida was chosen, specifically West Palm 

Beach, to represent conservative exposure estimates because the precipitation is on average 

greater in this region of the country compared to other areas (e.g., Fresno, California). The 

scenario uses weather data from West Palm Beach, FL (W12844). The scenario, in its entirety is 

included below.

Appendix F. Residential Modeling Approach 

Estimation of the fraction of the watershed area which receives application on impervious 

surfaces in residential watersheds 

 This appendix was developed as a generic guidance to characterize the approach and 

provide justification for the method for calculating the impervious surfaces in a watershed for 

aquatic modeling in ecological risk assessments. The exact numbers for the percent of 

impervious surfaces varies depending on the exact dimensions used for sidewalks, driveways, 

patios, and other impervious surfaces. Specific area estimates are not exact estimates and were 

not used in the indaziflam assessment; the approach was used to estimate the fraction of a 

watershed that could potentially receive applications of indaziflam. 

 As will be described below, this appendix describes the method used for calculating the 

fraction of the watershed that is impervious surface and that receives an application of a pesticide 

applied to lawns or ornamental plants in a representative urban/suburban watershed in California. 

This approach can be applied to other urban/suburban environments in the lower 48 states; 

however, the estimates of area are based on data from California. Three parameters describing 

the watershed, the average lot size, the average basal size or ‘footprint’ of the houses in the 

watershed and the fraction of impervious surface in the watershed are necessary to make this 

calculation. These three values are then combined, along with an assumption about the width of 

the bands of treated impervious surface from the edge of the lawn, or treated area, to estimate the 

fraction of the residential watershed that is treated impervious surface. 

 The procedure for estimating this fraction is 1) Estimate the fraction of the watershed that 

is impervious; and that which is lawn, 2) estimate the average lot size, 3) estimate the dwelling 

footprint, 4) construct a standard lot with an impervious surface consisting of the house, 

sidewalks, and driveway, 5) estimate the area of treated impervious surface associated with each 

lot 6) estimate the number of lots in a standard 10 ha watershed, 7) and finally, estimate the 

fraction of the total watershed that is treated impervious surface. 

1) Estimate the fraction of the watershed that is impervious surface 

 In general, the majority of occupied areas including core areas and critical habitat (as 

defined by FWS) and occurrence data from CNDDB are located in areas where the percentage of 

impervious surface is less than 20%. However, a few selected areas with higher percentages of 

impervious surface (e.g. San Francisco Bay region) were evaluated to determine a representative 

value for residential settings. The conceptual model for the ROW scenario assumes that the 

watershed is represented by equal portions of impervious and pervious surface (50%). Based on 

geospatial data, it is evident that the areas with the highest percentage of impervious cover are 

urban areas outside the occupied areas, and, in general, the occupied areas have impervious 

surface of less than 50% (Figure F-1). Therefore, for purposes of modeling, it is assumed that a 

representative percentage of impervious cover is 50%. In general, as the percentage of 

impervious surface increases, the overall exposure resulting from applications to the pervious 

surface decreases because less mass is applied within the watershed. Additional information on

the impact of this assumption has been previously characterized in the Barton Springs 

salamander endangered species risk assessment for atrazine (U.S. EPA, 2006).

2) Estimate for the typical lot size 

 In order to justify the assumption of 1⁄4 acre lot as a typical exposure scenario, publicly 

available data from the United States Census (Census) 2003 American Housing Survey (AHS) 

was reviewed on July 10, 2006 and is available at the following website. 

http://www.census.gov/hhes/www/housing/ahs/ahs03/ahs03.html

Data for all suburban homes available nationally was considered. It is assumed that most 

residential pesticide applications will occur in suburban settings. In order to test the assumption 

of the 1⁄4 acre lot as the best representation, the AHS data for suburban homes that list total 

number of houses by lot size and by square footage of house (see Table 1C-3 at the AHS website 

above) was evaluated. With a total of 45,552,000 total units reported nationally for all suburban 

areas, 12,368,000 units (the largest class at 27%) were on lots between 1/8 acre and 1⁄4 acre, 

while 9,339,000 units (the second largest class at 21%) were on lots between 1⁄4 acre and 1⁄2 acre. 

Overall, the median lot size was 0.37 acre. This analysis suggests that the 1⁄4 acre lot is a 

reasonable approximation of suburban pesticide use. 

3) Size of House Footprint 

 The AHS survey data reports that of a total of 43,328,000 reported single detached homes 

in suburban areas, 10,124,000 (the largest group at 23%) were between 1,500 and 2,000 square 

feet, while 7,255,000 (the third largest group at 17%) were between 2,000 and 2,500 square feet, 

and 9,513,000 (the second largest group at 22%) were between 1,000 and 1,500 square feet. 

From these data, it was assumed that a typical home is 2,000 square feet with a 1,000 square foot 

footprint. The lower sized houses less than 1,500 square feet are more likely to represent single 

floor structures; thus, the 1,000 square foot estimate for a house footprint is reasonable. 

4) Development of a standard lot 

 Using a quarter acre lot and a house with a 1000 ft2

 footprint, a standard lot was 

developed (Figure F-2). Both the lot and house were assumed to be square, resulting in the side 

of the lot being 104.4 ft in length and the side of the house being 31.6 ft. If the house is placed in 

close to the center of the lot, the driveway will be 50 ft long. If the driveway is assumed to be 15 

ft wide, then the driveway is 750 ft2

. For sidewalks, it’s necessary to consider whether it is a 

corner or mid-block lot. If we assume that the driveway is 3 ft wide, the area of the sidewalk is 

the width of the yard minus the width of driveway time three, or 268.2 ft2

 for the mid-block lot 

and 572 ft2 for the corner lot (268.2 + 104.4x3 – 9), the 9 ft2 are subtracted to account for the 

overlap where the sidewalks meet. Therefore, the total impervious surface, (house + driveway + 

sidewalk + patio) for the mid-block lot is 2318 ft2

 and 2622 ft2 for the corner lot. This leaves 

8,572 ft2 and 8,268 ft2 of lawn for the two lot types respectively. Removing the house from the 

calculation of impervious surface leaves 1318 ft2

 for the mid-block lot, and 1622 ft2 for the 

corner lots.

Figure F-2. Standard lot for assessment of aquatic exposure from applications of pesticide to residential settings in 

California for the California. The schematic represents a corner lot. Mid-block lots have side walk only along the 

front of the lot and the area of the sidewalk is 268.2 ft2

 rather than 572 ft2 with a resulting increase in lawn area to 

9,075 ft2

. 

5) Area of treated impervious surface per lot for lawn applications 

 The area of treated impervious surface is estimated by assuming the whole sidewalk, and 

3 ft of the driveway and street along the road get treated. This represents what might occur if the 

homeowner is using a broadcast spreader and makes no effort to avoid applying pesticide to hard 

surfaces bordering the lawn. In this scenario, 268.2 ft2 of side walk is treated during an 

application for the mid-block lot, and 581.4 ft2 for the corner lot. This is derived from the 

assumption that the perimeter of the property is planted with ornamental plants which are located 

on the property side of the sidewalk. An alternative scenario for treatments results in 799.7 ft2

treated surface on a mid-block lot (218.4 +313.2 + 268.1) and 1416 ft2 for a corner lot (See 

Figure F-3). Figure F-3 was developed for home lawn applications, however the logic is similar 

except the amount of impervious area that receives treatment is much less.

6) Number of lots in a 172 ha watershed. 

 In step 1 above, the fraction of the watershed that is in lawn was estimated to be 50%, 

with the balance being impervious surface, which includes, dwellings, sidewalks, driveways and 

streets. Since we now have an estimate of the treated impervious area associated with each lot, in 

order to estimate the total treated impervious surface, we need an estimate of the number of lots 

in the watershed. Current drinking water risk assessments assume a standard watershed size of 

172.2 ha, or 18,535,453.7 ft2

. There is an assumed area in the index reservoir watershed that 

would not be planted (e.g., turf or other ornamentals) and would not have a residential lot 

(e.g.,stream network of rivers, streams, drainage ditches, etc.). The assumed total area of the 

stream network in the index reservoir watershed consists of 2200 m2

 of perennial streams and 

3800 m2 of ephemeral streams, for a combined land area of 6000 m2 (US EPA, 1999). This area 

is subtracted from the total watershed area in the calculation of the number of 1⁄4 acre lots in the 

watershed (18,535,453.7 ft2

 - 64,583 ft2 = 18,470,871). If we assume that the lots are arranged in 

blocks of ten (Figure F-4), then 2/5 of the houses will be corner lots and 3/5 will be mid-block. 

Using these fractions, and the lawn areas calculated in step 4, we can estimate the number of 

houses as 2/5x 8268xN + 3/5 x 8572xN = 18,470,871. Solving this equation for N, the number of 

lots gives a value of 2185.8 or approximately 2,186 lots in the watershed.

7) Fraction of treated impervious surface in the watershed. 

 If there are 2186 lots in the watershed, as in Figure 4, then 874 are corner lots and 1311 

are mid-block lots. Using the treated areas estimated in step 5, the treated area in the watershed is 

1416 ft2

 x 874 = 1,237,584 ft2 for the corner lots and 799.7 ft2 x 1311 = 1,048,406 ft2 for the 

mid-block lots, for a total of 2,285,990 ft2

. Since the total watershed area of 172.2 ha is 

equivalent to 18,535,453 ft2

, the percent of the watershed that is treated impervious surface is 

12%.
