The Environmental Fate and Effects Di vision (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 cour ses, ball parks, commercial forests, Christmas tree farms, citrus fruit, stone fr uit, pome fruit (apples, pears, quinces, and Asian pears), grapes, tree nuts, and olives. Indazi flam controls weeds by inhibi ting cellulose biosynthesis (CB Inhibitor). Its primary sites of action are inhibi tion of seedling emergence and root development. This assessment is based on proposed maxi mum application rates for all uses.

EFED calculated drinking water concentrations for total indaziflam residues which includes indaziflam and similarly structured degr adates. EFED also calculated concentrations separately for the indaziflam degradate, floroe thyl-diaminotriazine (diami notriazine, FDAT) plus floroethyl-dihydroaminotriazine (dihydroaminotri azine, ROI1; a degradate of diaminotriazine), which the Residues of Concern Knowledgebase Subcommittee (ROCKS) reported to be of toxicological concern (D371659). ROCKS also re ported 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 inda none, indaziflam-carboxyl ic 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 indazi flam and, more importan tly, its residues have a potential to leach to ground wate r. Indaziflam is classified as moderately mobile, however transformation products of indaziflam are mobile to highly mobile and we re detected in field studies at depth. Further, data s how 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 resi dues of indaziflam are a concern for exposure via ground water. However, there is uncer tainty 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 th e 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 a ll field studies. Detections below the LOQ are not accurately characterized becau se 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 produc ts. Replicate values below the LOQ were assumed at 1⁄2(LOQ + LOD) for calcula tions 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 indazi flam residues in drinking water source water (pre-treatment) resulting from proposed labeled use on sites that are considered vulnerable to pesticide contamination resulting from labe led use practices. Estimated drinking water concentrations (EDWCs) are included for ind aziflam + 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 leachi ng was assessed with the screening model SCIGROW.

The major degradates observed in laborato ry and field studies are summarized in Table 2.1 . The table also shows the fate studies in which the degradates we re identified and the maximum formation in each study. The Health Effects Division (HED) has reported that all transformation products that maintain a similar chem ical structure to the pa rent (dual triazine and indane rings - - triazine inda none, indaziflam-carboxylic acid, indaziflam-olefin, indaziflamhydroxyethyl), and the diaminotriazi ne degradate are of toxicologi cal concern. This assessment includes consideration for the exposure of both in daziflam + similarly st ructured transformation products and diaminotriazine, wh ich are addressed separately.

### Page 5 of 131 2.1. Background

Bayer CropScience is seeking registration fo r 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 persiste nt to persistent in aer obic soil, persistent in aquatic environments, and persistent under anaer obic conditions (both terrestrial and aquatic). Indaziflam controls weeds by inhibiting cellulose biosynthesis (in the cl ass 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 pres ent in the technical grade product in the following percentages: 95-100% isom er A, and 0-5% isomer B. This assessment is part of a national registration requ est for selective pre emergence a nd post emergence control of many annual grasses and broadleaf weeds including cr abgrass, goosegrass, annual bluegrass, and annual sedges in turf, citrus fruit, stone fruit, po me 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 tu rf (sports turf), golf courses (prohibited on greens), sod farms, ornament als, 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 a nd 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 establishe d 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, potassi um 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.

Indaziflam 200 SC Herbicide: 19.05% indaziflam; used on citrus fruit, stone fruit, pome fruit, grapes, tree nuts, pi stachios, 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, pi stachios, 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 Fruit 1 

### , 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 fa rms, and other non-crop ar eas (railroad and rail yards, managed roadsides, fence rows, utilitie s, other industrial, m unicipal, and government sites). End-use products assessed in this docum ent are formulated as a dry granule (Lawn 3FL Herbicide Granule), water soluble packets (BCS-AA10717 20WSP), liquid concentrate (Lawn 3FL Herbicide Concentrate), suspension concentr ate (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 Ferti lizer), 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 I ndaziflam 500SC have higher single maximum application rates fo r fine textured soils than for coarse textured soils (0.085 lbs a.i/A and 0.065 lbs a.i./A, respectiv ely). The fine textured soil ap plication rate ( 0.085 lbs a.i./A) was used for modeling in this exposure assessmen t. For purposes of this assessment, drinking water exposure estimates are based on maximum propos ed label rates for six use categories: food (citrus, stone fruit, tree nuts, a nd vine crops), turf (golf courses, athletic fields, and sod farms), residential lawns, ornamentals and hardscapes, forestry, and other non-cr op areas (railroad and rail yards, managed roadsides, fence rows, utilit ies, other industrial, m unicipal, and government sites).

### 2.3. Conceptual Model

Indaziflam is a moderately mobile to mobile chemical that is expected to be relatively persistent in the environment in aerobic conditio ns, and persistent in anaerobic conditions. Residues of concern for exposure include tria zine-indanone, diaminotri azine, indaziflamcarboxylic acid, indaziflam olefi n, and indaziflam-hydroxyethyl. Re sidues of concern are more

### Page 8 of 131 mobile than the parent compound. Indaziflam a nd its residues are likely to reach surface water resources via spray drift or runoff, and ground wa ter resources via leaching from use sites.

3. ANALYSIS

3.1. Fate and Transport Characterization

The general physical/chemi cal properties of indaziflam are summarized in Table 3.1

. Environmental fate and transport pr operties of indaziflam are char acterized 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 environmenta l 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 diaminot riazine. Drinking water exposure estimates were generated for this major degradate.

### Page 9 of 131 Indaziflam is expected to be moderately mobile in soil, moderately persistent to persistent in aerobic soil, persistent in anerobic soil, and persistent in aerobi c and anaerobic aquatic environments. Indaziflam is a racemic mixture of two stereoisomers with a ratio of isomer A toisomer 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 e xpected 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 mode rately 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 diami notriazine which was detect ed in field studies at the maximum soil segment depth, and was detected over multiple time points. Indaziflam was detected in the submitted terrestrial field diss ipation studies above th e level of quantitation (LOQ) at depths up to 45-60 cm; however the major ity of detections were restricted to the 0-15 cm range in the soil profile, with a few det ections above LOQ in the 15-30 cm, and 30-45 cm depth. It was also detected below th e 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 gr ound water, specifically diaminotriazine. That compound was detected at deeper de pths in the field studies comp ared to the other degradates, and is highly mobile. A prospective gr ound water study (PGW) would help to further characterize the extent of the pot ential impact on ground water quality.

### 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 so luble 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 K ow 

### for indaziflam at 40oC for pH 7 was 631, where pH>pK a 

### , and was undetermined at pH< pK a 

### (MRID 47443202).

Indaziflam is moderately mobile to mob ile based on FAO Soil Mobility Classification Guidance (USEPA, 2006), with reporte d Freundlich adsorption values (K f 

### ) from five soils

### Page 13 of 131 ranging from 6.1 to 11.1 (0.885) (MRID 47443203). Batc h equilibrium data for indaziflam show that adsorption to soil is not well correlated w ith organic carbon content. The coefficient of variation (CV) for K oc 

### (27%) is larger than that for K f 

### (21%). Further, K f 

### was not well correlated with percent organic carbon (r 2 

### = 0.187, p = 0.47), nor with pH (r 2 

### = 0.001, p = 0.95), nor percent clay (r 2 

### = 0.005, p = 0.91).

Leaching and adsorption/desorption studies were conducted on the identified three major degradates 1 

### : triazine-indanone, diaminotriazine, a nd indaziflam-carboxylic acid. These compounds are more mobile than the parent. Diaminotriazine and indaziflam-carboxylic acid have low soil-water partiti oning coefficients (respective K f 

### values ranged from 0.16 to 0.78 and from 0.47 to 1.32). Diaminotriazine and indazifl am-carboxylic acid are mobile to highly mobile compounds, based on the FAO Soil Mobility Classi fication Guidance (USEPA , 2006). Triazineindanone is moderately mobile in soil, although still mo re mobile than the parent indaziflam (K f 

### ranging from 3.00 to 5.97; MRID 47443204).

Compounds with K f 

### values less than five trigge r a ground water advisory (USEPA, 2008a). The major degradates of indaziflam (tri azine-indanone, diaminot riazine, and indaziflamcarboxylic acid) present a potential ground water con cern in some soils, espe cially those that are sandy and have low organi c carbon content (all K f 

### 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 irradi ated, combined label, correcte d environmental photodegredation half-life in soil of 40.3 da ys in loamy sand at pH 6.5, OC 2.4%; MRID 47443209).

Indaziflam biodegrades in 35 to 178 days in aerobic soil (parent-on ly half-lives; MRID 47443210, 47443211, 47443212, 47443213). Un-extracted resi dues were substantial (17 – 34 %) in all aerobic soil metabolism studies. Multiple solvent syst ems were not employed in the extraction scheme; therefore it is uncertain wh ether 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 metabolis m studies on six different soil types show indaziflam degrades via oxidation of the indany l moiety to indaziflam -triazine indanone and indaziflam-carboxylic acid. Inda ziflam, indaziflam-t riazine indanone and indaziflam-carboxylic acid are cleaved at the N bridge to form di aminotriazine from the triazine moiety and unidentified minor compounds from the indanyl moiety. Residues are ultimately converted to bound residues and CO 2

1 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 c onducted for indaziflam investigating the biotransformation of [triazine-2,4- 14 

### C]- and [indane-3- 13/14 

### C]-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 residue s. Half-lives were calculated for parent only, and for parent and un-extr acted residues combined. The rate of biodegradation of indaziflam was slower in aquatic environments than terrestrial environments (parent-only nonlinear first order half-lif e 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-e xtracted residue non-linear fi rst order half-lives of 257 days, and 462 days, respectively). The compoun d quickly dissipated out of the water column (water dissipation half-l ife of 0 to 3 days), and was detected in the sediment. The major indentified degradates were triazine-indanone, di aminotriazine, and indazi flam-carboxylic acid. In anaerobic aquatic environments, indaziflam is stable to biodegradation; there was no evidence of degradation (MRID 47443218, 47443219).

Figure 3.1 Predicted Transformation Pathway under Aerobic Conditions

### Page 15 of 131 3.1.3. Field Studies

Eight terrestrial field dissipat ion studies were conducted for in daziflam 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 a dditional 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 broadcas t once at a target application rate of 0.165 kg a.i./ha (0.147 lb a. i./A), which is great er than the proposed maximum application rate of 0.125 lb a.i./A (for use on forested areas). Indaziflam di ssipation 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 ra pid dissipation under field conditions compared to the laboratory degradatio n studies (dissipation half-lives fo r 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 ind aziflam 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 indazifl am 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 calculati ons 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 te rrestrial 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 indi cate that indaziflam and more importantly its transformation products have a poten tial 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 betw een losses due to degradation and losses due to off-site transport (e.g., via r unoff to surface water, leaching to ground water, eroded soil or by air). Under field conditions, calc ulated 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 terminat ion (554 and 545 days, MRID 47443222 and MRID 47743320). Dissipation half-lives for studies that examined plots cr opped with turf were longer than those calculated from bare soil sites (9.3 – 59.2 days for ba re 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 produc ts in all eight fi eld studies were diaminotriazine, triazine-indanone, and ind aziflam-carboxylic acid. These compounds were

### Page 16 of 131 detected in the 0-15 cm depth at maximum mean parent-equivalent conc entrations of 17.6% (at 28 days), 9.1% (at 28 days), and 5.1% (at 28 da ys) of the theoretical day-0 recovery of indaziflam, respectively. Triazi ne-indanone and indaziflam-carboxyl ic 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-carboxyl ic 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 treatmen t; 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 evalua tion of bioaccumulative compounds [64 Fed. Reg. 60194-60204 (November 4, 1999)].

3.1.5. Environmental Degradates

The transformation products re sulting from the environmenta l degradation processes of indaziflam are: triazine-i ndanone, indaziflam-carboxylic ac id, 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 mode rately persistent to persistent. Major degradates that are structurally similar to the parent include tria zine-indanone, indaziflamcarboxylic acid, indaziflam-hydroxyet hyl, and indaziflam-olefin. Ch emical 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 indazifl am-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 CO 2 

### . The maximum amounts of these degradation products observed in hydr olysis, aerobic aquatic metabolism, anaerobic

### Page 17 of 131 aquatic metabolism, soil column leaching, and aq ueous photolysis studies are summarized in Table 2.1

.

Chemical structures for minor degradati on products were not reported in any study and the percent of formation was frequently belo w 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 radia tion in aerobic aquatic systems (MRID 47443217).

A meeting held by OPP’s Residues of C oncern Knowledgebase Subcommittee (ROCKS) on November 19, 2009 concluded that ba sed on the uncertainty due to lack of toxicity data on the major degradates (triazine-indanone, indazifl am-carboxylic acid, diaminotriazine, indaziflamhydroxyethyl, and indaziflam-olefin), all residues that maintain the parent “dual-ring” structure, and diaminotriazine must be included as resi dues of concern for the drinking water exposure assessment (D371659). Environmenta l half-lives were recalculated based on the conclusions from the ROCKS. Therefore, a total toxic resi dues approach was used for this assessment for aquatic exposure to evaluate th e potential exposure to th e residues of indaziflam that retain the dual ring structure, i.e ., indaziflam, triazine-indanone, inda ziflam-carboxylic acid, indaziflamhydroxyethyl, and indaziflam-olefin. Exposure to di aminotriazine is calculated separately since it is expected to have a distinct mode of action and toxicological endpoint compared to indaziflam. Structural analysis suggested th at 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 de gradation 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 Pane l, in October, 2008, was followed to calculate total toxic residues of concern (parent plus triazine-inda none, indaziflam-carboxylic acid, indaziflam-hydroxyethyl, and i ndaziflam-olefin) (USEPA, 20 08b). Application rates for indaziflam were used to represen t the total mass loading of pestic ide 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 (K f 

### ) of the most mobile degradate (i.e., indaziflam-carboxylic acid). This is a conservative assumption. In reality, indaziflam a nd the various degradates will be transported in the environment at varying rates.

Diaminotriazine was modeled separately for dr inking water exposure es timates as there is a separate toxicological endpoint . The half-lives were based on a supplemental aerobic soil metabolism study (MRID 47443214). The modeling a ssumed 100% conversion of indaziflam to diaminotriazine, therefore, appli cation rates for diaminotriazine were the same as the equivalent indaziflam applications adjusted by the molecular weight ratio (157/301). Th is is a conservative assumption, but reasonable as diaminotriazine is the terminal degradate in the proposed degradation pathway.

### Page 18 of 131 3.2. Drinking Water Exposure Modeling

Estimated drinking water concentrations (EDW Cs) were generated using OPP’s standard suite of models. The proposed use patterns for pe rennial tree and vine crop s (citrus, stone fruit, pome fruit, grapes, tree nuts, pistachios, olives), pre emergent and post em ergent 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 roadside s, fence rows, utilities, other industrial, municipal, and government sites) were assessed. Dr inking 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 thr ough runoff and spray drift. The PRZM model simulates pesticide movement and transformation on and across th e agricultural field resulting from crop applications. The EXAMS model simulates pestic ide loading via runoff, erosion, and spray drift assuming a standard watershed of 172.8 ha that dr ains into an adjacent standard drinking water index reservoir of 5.26 ha, and an average depth of 2.74 m. A more deta iled 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 fr om 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 ma y be planted with the modeled crop. PCAs are applied to concen trations predicted by PRZM/EXAMS.

Screening Concentration in Ground Wate r (SCI-GROW v2.3, Jul. 29, 2003) is a regression model used as a scr eening tool to estimate pesticid e concentrations found in ground water used as drinking water. SCI-GROW wa s developed by fitting a linear model to ground water concentrations with the Relative Index of Leaching Potential (RILP) as the independent variable. Ground water concentr ations were based on measurem ents 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 (K oc 

### ). 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 cont amination. The SCI-GROW model and user’s manual may also be downloaded from the EP A Water Models web- page (USEPA, 2006).

3.2.2. Input Parameters

Currently approved PRZM scenarios were us ed 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. Applicat ion methods and rates were obtained from the proposed labels. Application timi ng of indaziflam is related to various pest pressures (e.g., weed germination). The label states that “for best results” apply indazi flam prior to weed germination. This is a recommended applicati on timing, and is not an enforceable application practice; there are no prohibitions on year-round app lications of indaziflam. Therefore, for the purposes of this assessment, initial application dates were select ed in order to reflect labeled crop timing for applications, weather file data, and pest pres sure 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 ba se on email communications wi th Bayer CropScience through the Risk Manager (Erik Kraft, Regist ration 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 unknow n toxicity, therefore we re included in this exposure assessment. Total toxic residue half-l ives 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 90 th 

### percentile confidence on the mean of the total toxic residue half-lives, used in the dri nking water exposure modeling, are presented in Table 3.4

.

The degradation studies we re characterized by large amount of un-extracted and uncharacterized material; thus there is consider able uncertainty regarding the degradation of indaziflam residues in the environment. To characterize this uncertainty, model simulations were completed using two sets of environmenta l half-lives: 1) high-e nd conservative estimates which were completed using half-lives that incl uded un-extracted residues, and 2) the low-end estimates based on half-lives that excluded un-ex tracted residues. Model results using the upperbound conservative half-lives ar e presented in this assessment; the range between the lower bound and the upper bound was not that gr eat (no more than 26% difference 1 

### ), 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 watershe d 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.

1 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 availa ble 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 us e. 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 develope d to represent a watershed that was more vulnerable than most watersheds to pesticide contamination. It repres ents a real drinking water reservoir in Illinois, Shipman City Lake. The geometry for the index re servoir 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 i ndex reservoir can be found in th e guidance for using the index reservoir (U.S. Environmental Protection Agency, 2000).

For the hardscape use, a provisional scenar io (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 gr avel areas, along fence lines). The Florida impervious scenario was modified from an existing California impervious scenario (CAimperviousRLF.txt) developed for the endanger ed species assessments in California. The provisional scenario represents a conservative hi gh-end exposure resulting from applications of indaziflam to hardscapes in West Palm Beac h. 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 B each, FL (W12844). This scenario is included in Appendix C , along with brief descriptions of each s cenario 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, pr oposed label applic ation rates, and management practices. Chemical specific i nput 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 indazi flam + similarly stru ctured residues were completed using the mean Fre undlich adsorption coefficient (K f 

### ) for the most mobile degradate (i.e., the lowest K f 

### ); this was used as a conservative assumption for the mobility of the compound. For the hards cape scenario, the K f 

### 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., K f 

### = 0.84, the mean K f 

### of most mobile degradate) forces some amount of infiltration, thus underestimating the concen tration of indaziflam in runoff. Therefore, the K f 

### for indaziflam + similarly structured resi des 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 es timate surface water concentrations as there is some amount of binding that will occur in the reservoir.

The surface water model estimates for hardscap es, are conservative estimates of drinking water concentrations since it assumes that 100 % of the 172 ha waters hed 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 cons ervative 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 co nservative assumption. Exposure estimates for hardscape applications are char acterized in further detail in Section 4.0

### Page 24 of 131 3.2.4.2. Model Results: Ground Water Concentrations of Indaziflam + Similarly Structured Residues

### 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 de gradate 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 dihydroaminotri azine (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 expos ure 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 rati o (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 registra nt studies) that this transfor mation would occur rapidly (e.g., within days). Rapid formation of diaminot riazine 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 simultane ously. For example, in the calculation of diaminotriazine EDWCs, it was assumed that rapid transformation of indaziflam to diaminotriazine occurred; whereas in the calc ulation 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 in daziflam residues are not intended to represent concurrent exposure concentrations.

Methods for modeling applications of diami notriazine to hardscapes were described above in Section 3.2.4.

### 3.3. Monitoring Data

Indaziflam is a new chemical, therefore ther e 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 tran sformation products. Ther e is also uncertainty associated with the formation of the degradate di aminotriazine (which was modeled separately). Degradation quantification was confounded by larg e amounts of un-extracted material that was reported in the degradation studies conducted with soil for both i ndaziflam and diaminotriazine. The amount of un-extracted and uncharacterized material hindered accurate estimation of degradation rates. Another uncertainty is th e formation rate of diaminotriazine. Although proposed pathways for degradation (included with submitted studies), suggest that diaminotriazine is formed during nearly all de gradation processes, a nd it was increasing in concentration at the termination of those studies where it was dete cted. These uncertainties have led to the conservative expos ure assessment described here.

An additional source of uncertainty is the mobility of indaziflam and its degradates. We assumed, based on the methodology outlined in th e PBT SAP white paper (USEPA, 2008), that indaziflam + similarly struct ured residues have similar ch emical, 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 fo r 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 fi eld. It is not likely (as supporte d 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 indazi flam 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 quantita tion (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 pot ential of indaziflam and its major transformation products. Replic ate values below the LOQ were assumed at 1⁄2(LOQ + LOD) for calculations of dissipation half-lives.

There is also uncertainty associated with th e 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 applicati on dates. Although the pesticide application dates were selected to be most appropriate with considerations for label restrictions , recommendations, and simulated cropping dates, variabil ity nevertheless results because the time span that a pesticide may likely be applied may be large and the actual application da tes 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 residentia l uses so a PCA of 1 was applied to these uses. A PC A of 1 for turf and non-ag uses (residential lawns, hardscapes, forestry, and other non-crop areas) assumes that th e entire watershed is in that modeled use (e.g., turf) and is simultaneously treated, which is a cons ervative assumption. To the extent that actual use patterns are less than the labeled maximums and the location-specif ic PCAs are less than assumed in this assessment, actual envir onmental exposures could be lower.

There is additional uncertainty associated w ith 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 repres ent actual use patterns (e.g., hardscapes may be spot treated, not all areas in a watershed are simu ltaneously treated). To the extent that actual use patterns differ from modeling assumptions, act ual environmental concen trations in drinking water could be lower. However, there is th e uncertainty regarding the cumulative exposure resulting from all residential us es of indaziflam (hardscapes, ornamentals, and home lawns). Conceptually, these use patterns co uld occur at the same time, t hus 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 hardsc ape uses of indaziflam (e.g., driveways, patios, sidewalks, fence lines) conservatively assumed 100% of the watershed was impervious and received applications of i ndaziflam. 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 sy stem 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 wa tershed 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 Chesapeak e Bay Endangered Species Assessment (USEPA, 2006b), which was further refined in the Pestic ide Effects Determination for the Risks of Carbaryl Use to the Federally-Listed Ca lifornia Red Legged Frog (USEPA, 2007). The approach we used to characterize the exposur e estimates resulting from applications of indaziflam on hardscapes was the similar to thes e two assessments, however the dimensions of the watershed were adjusted to represent the i ndex reservoir, thus the number of lots in the watershed increased.

Further, there is an assumed area in the index reservoir watershe d that would not be planted (e.g., turf or other or namentals) and would not have a residential lot (e.g., stream network of rivers, streams, draina ge ditches, etc.). The assumed total area of the stream network in the index reservoir wa tershed consists of 2200 m 2 

### of perennial streams and 3800 m 2 

### of ephemeral streams, for a combined land area of 6000 m 2 

### (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 watershe d 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 appli cations area (i.e., waterways, dr ainage ditches, etc.). There could conceivably be approximately 2,186 lo ts 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 indazi flam ([1/4 acre lot (10,890 ft 2 

### ) x 12% impervious surface x 2186 lots / 18,470,871 ft 2 

### 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 lan duses in the simulated watershed is listed below.

Total Watershed Area = 172.2 ha (18,535,453 ft 2 

### ) 50% pervious area Stream network = 4% (741,418 ft 2 

### ) 50% impervious area (roadways, driv eways, sidewalks, patio, house) Impervious Area (potentially treated; driveways, sidewalks, patio) = 15% (2,780,318 ft 2 

### ) Impervious Untreated (roadw ays, and houses) = 35% (6,487,408 ft 2 

### )

The conceptual model for applications to hardscape has two conservative assumptions. First, it assumes that indaziflam could be applie d to all of the 15% impervious surfaces on a 1⁄4 acre lot. Second, it assumes that all hards capes are treated simultaneously. Additional refinements could include variation in the per centages of impervious surfaces that received

### Page 32 of 131 treatment in the 1⁄4 acre lot to simulate differenc es 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 re sulting from applications of indaziflam + similarly structured residue s 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 tota l 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 generate d 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 ge nerally good, with a few large uncertainties. The degradation studies were charac terized by large amounts of un-e xtracted and uncharacterized residues, thus there is considerable uncertainty regarding the degradation of indaziflam in soil and aquatic systems. To addr ess this uncertainty, model estimates were completed using two sets of aerobic metabolism half-lives for indazifl am + degradates, and diam inotriazine; 1) parentonly + degradates, and 2) parent + un-extracted residues + degr adates. The model simulation results are bounded by the conservative upper- bound estimates using parent + un-extracted residues + degradates, and the lower-bound pa rent-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 charac terized 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. Th e 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 woul d 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 water 1 

### . 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 EDWC s 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 hard scapes, turf, and other non-ag uses is a conservative estimate of drinking water concentra tions since it assumes that 100% of the 172 ha watershed is treated w ith indaziflam. Actual use pattern s 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 degrad ates of indaziflam, particularly diaminotriazine to leach to ground water and impact ground water quality. Diami notriazine was detected at deeper depths in the field studies compared to the parent and other de gradates; 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 tr ansported to ground water.

1 For the purposes of summarizing results, only the upper -bound (parent + un-extracted residues + degradates) results are presented here.

### The field used to represent citrus production is in Florida, locate d 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 ju ice market and among the highest for the fresh market. The field has Wabasso fine sand, wh ich 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 producti on 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 (7 th 

### to 8 th 

### overall) in the U.S., and is one of the southern most production areas. There ar e four primary apple prod uction areas in western North Carolina, all long-term pere nnial 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, me sic, Typic Kanhapludults. Hayesville loam is a Hydrologic Group C soil. The weather data is from weather station W03 812 in Ashville, North Carolina.

For the stone fruit use, a field represen ting 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. Accordin g to the 1997 Census of Agriculture, Oregon is the leading state in the producti on 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 Hy drologic 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 Ge orgia (MLRA133) and the weat her 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 southwes tern 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 us ing 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 concen trated in the western part of the state where the macroclimate is best suited for grape produc tion. New York is among the leadi ng Eastern U.S. state in both wine and table grape production. Chautauqua Co unty has the highest acrea ge in the state and New York remains the 3 rd 

### or 4 th 

### 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 us ing a scenario intended to represent olive production in California’s San Joaquin Valley, pr imarily 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 (US DA, 1999). Nearly 65% of California’s olive acreage is located in the San Jo aquin Valley, primarily in Tulare County (53% of the total) (USDA, 1999). Moreover, based on 2005 Califor nia Pesticide Usage Reporting (CalPIP, 2006), approximately 80% of pesticides used on Califor nia 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 w eather 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 essentia lly generic, with no dis tinction 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 fo r 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. Fo r 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 in tended to be used as a surroga te 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 dur ing the wet season. Tierra soils were chosen to represent residential areas. Tierra is a Hydrologic Group D soil which a ccount for approximately 40% of urban soils in drainage, these soils are fine allu vial deposits. The weathe r data is from weather station W23234 in San Fransisco, CA.

Indaziflam use on forestry was represen ted by a surrogate scenario, North Carolina Apples (NCapplesSTD.txt). This scenario is descri bed above. It was sel ected as a surrogate to represent a vulnerable scenario for forestry appl ications due to the precipitation that it receives, and the soil types. It is reasonabl e to use the apple scenario as a surrogate for forestry uses since the apple tree is physiologically simila r to commercial forestry trees.

For the hardscape use, a provisional scenar io (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 gr avel areas, along fence lines). The Florida impervious scenario was modified from an existing California impervious scenario (CAimperviousRLF.txt) developed for the endanger ed species assessments in California. The provisional scenario represents a conservative hi gh-end exposure resulting from applications of indaziflam to hardscapes in West Palm Beac h. 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 Beac h, FL (W12844). The scenario, in its entirety is included below.

## Appendix F. Residenti al 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 calculatin g 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 appr oach was used to estimate the fraction of a watershed that could potentially r eceive 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 a pplication of a pesticide applied to lawns or ornamental plants in a repr esentative urban/suburban watershed in California. This approach can be applied to other urban/suburban enviro nments 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 impe rvious surface in the watershe d are necessary to make this calculation. These three values ar e then combined, along with an assumption about the width of the bands of treated impervious surface from the e dge of the lawn, or trea ted area, to estimate the fraction of the residential watershed th at 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 sta ndard lot with an impervious surface consisting of the house, sidewalks, and driveway, 5) estimate the area of treated impervious surfac e associated with each lot 6) estimate the number of lots in a standa rd 10 ha watershed, 7) and finally, estimate the fraction of the total watershed that is treated impervious surface.

1) Estimate the fraction of the wa tershed that is impervious surface

In general, the majority of occupied areas including core areas a nd critical habitat (as defined by FWS) and occurrence data from CNDDB are located in areas wh ere 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 im pervious and pervious surface (50%). Based on geospatial data, it is evident that the areas wi th the highest percentage of impervious cover are urban areas outside the occupied areas, and, in general, the oc cupied areas have impervious surface of less than 50% (Figure F- 1). Therefore, for purposes of modeling, it is assumed that a representative percentage of im pervious cover is 50%. In ge neral, 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.

### Page 128 of 131 2) Estimate for the typical lot size

In order to justify the assumption of 1⁄4 acr e lot as a typical expos ure 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/hous ing/ahs/ahs03/ahs03.htm l

Data for all suburban homes available nationally was considered. It is assumed that most residential pesticide applications will occur in su burban settings. In order to test the assumption of the 1⁄4 acre lot as the best representation, th e AHS data for suburban homes that list total number of houses by lot size a nd by square footage of house (see Table 1C-3 at the AHS website above) was evaluated. With a total of 45,552,000 to tal 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 th at 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 ho me is 2,000 square feet with a 1,000 square foot footprint. The lower sized houses less than 1,500 s quare feet are more likel y to represent single floor structures; thus, the 1,000 s quare foot estimate for a house footprint is reasonable.

4) Development of a standard lot

Using a quarter acre lo t and a house with a 1000 ft 2 

### 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, th e driveway will be 50 ft long. If the driveway is assumed to be 15 ft wide, then the driveway is 750 ft 2 

### . For sidewalks, it’s necessary to consider whether it is a corner or mid-block lot. If we a ssume that the driveway is 3 ft wide, the area of the sidewalk is the width of the yard minus the widt h of driveway time three, or 268.2 ft 2 

### for the mid-block lot and 572 ft 2 

### for the corner lot (268.2 + 104.4x3 – 9), the 9 ft 2 

### are subtracted to account for the overlap where the sidewalks meet. Therefore, th e total impervious surf ace, (house + driveway + sidewalk + patio) for the mid-block lot is 2318 ft 2 

### and 2622 ft 2 

### for the corner lot. This leaves 8,572 ft 2 

### and 8,268 ft 2 

### of lawn for the two lot types respectively. Removing the house from the calculation of impervious surface leaves 1318 ft 2 

### for the mid-block lot, and 1622 ft 2 

### for the corner lots.

### Page 129 of 131 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 ft 2 rather than 572 ft 2 with a resulting increase in lawn area to 9,075 ft 2

.



### 5) Area of treated impervious surf ace 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 make s no effort to avoid applying pesticide to hard surfaces bordering the lawn. In this scenario, 268.2 ft 2 

### of side walk is treated during an application for the mid-block lot, and 581.4 ft 2 

### for the corner lot. This is derived from the assumption that the perimeter of the property is pl anted with ornamental plants which are located on the property side of the sidewa lk. An alternative scenario for treatments results in 799.7 ft 2 

### treated surface on a mid-block lot (218.4 +313.2 + 268.1) and 1416 ft 2 

### for a corner lot (See Figure F-3). Figure F-3 was develo ped for home lawn applications , however the logic is similar except the amount of impervious area th at receives treatment is much less.

8672 - lawn 1000 - house 572 - sidewalk + 5 46- driveway 10,890 sq ft = 1⁄4

House dimensions: 31.6 ft x 31.6

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 trea ted impervious area associat ed with each lot, in order to estimate the total treated impervious surf ace, we need an estimate of the number of lots in the watershed. Current drinking water risk as sessments assume a standard watershed size of 172.2 ha, or 18,535,453.7 ft 2 

### . There is an assumed area in th e 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 d itches, etc.). The assu med total area of the stream network in the index rese rvoir watershed consists of 2200 m 2 

### of perennial streams and 3800 m 2 

### of ephemeral streams, for a combined land area of 6000 m 2 

### (US EPA, 1999). This area is subtracted from the total watershed area in th e calculation of the number of 1⁄4 acre lots in the watershed (18,535,453.7 ft 2 

### - 64,583 ft 2 

### = 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 calcul ated in step 4, we can estimate the number of houses as 2/5x 8268xN + 3/5 x 8572xN = 18,470,871. Solvin g this equation for N, the number of lots gives a value of 2185.8 or approx imately 2,186 lots in the watershed.

7) Fraction of treated impervio us 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 ft 2 

### x 874 = 1,237,584 ft 2 

### for the corner lots and 799.7 ft 2 

### x 1311 = 1,048,406 ft 2 

### for the mid-block lots, for a total of 2,285,990 ft 2 

### . Since the total waters hed area of 172.2 ha is equivalent to 18,535,453 ft 2 

### , the percent of the watershed that is treated impervious surface is 12%.
