This memorandum summarizes the drinking water assessment for the IR

- 4 New Use registration of Kanemite 15 SC ac e quinocyl , miticide, for fruiting vegetables (crop group 8), okra, edible podded beans, and hop s
. Acequinocyl is currently registered for almonds, tree nuts, pistachios, pome fruits, citrus, grapes, strawberries , and ornamentals. The application rates for the proposed uses are the same as the application rates for the currently registered agricultural uses ; i.e. 0.3 lb s ai/acre for the maximum single a pplication rate, with two applications allowed at a minimum interval of 21 days ( 0.6 lb ai/acre for a seasonal application rate)

. This assessment supersedes the previous drinking water assessment.

1. EXECUTIVE SUMMARY A Tier II screening

- level drinking water assessment was conducted for the proposed Section 3 New Use of acequinocyl (2

- (acetyl oxy)

- 3

- dodecyl

- 1,4

-naphthalenedione ; CAS# 57960

- 19

- 7 ; PC Code 006329 ) on fruiting vegetables (except cucurbits , field grown and greenhouse grown), okra, edible podded b eans, and hops . The assessment is based on the maximum proposed application rate of 0.3 lbs . a.i./acre/application for apple and tomato , applied by ground foliar spray two times every

21 days (Kanemite 15 SC; 15.8% a.i.; submitted July 30, 2009 ). In addition to the proposed new use on fruiting vegetables (except cucurbits field grown and greenhouse grown), okra, edible podded beans, and hops , this asses sment re

- evaluates the existing use on apples and pecans because the previous drinking water assessment (done in 2007 ) employed an older version of Perl shell interface program and older modeling input parameter guidance. Similar to the previous drinking water assessment, two approaches were used in performing the drinking water assessment for the proposed acequinocyl uses
. In Approach # 1, acequinocyl was conservatively assumed to be stable to all routes of degradation to account for the uncertainties associated with the environmental fate data . In Approach #2, total (acequinocyl + acequinocyl

OH) residues were modeled with the assumption that the metabolite acequinocyl

- OH (referred to as the R1 degradate in this assessment) is of toxicological concern . According to the HED Metabolism Assessment Review Committee (MARC) the residues of concern in the dietary exposure and risk assessment are acequinocyl and acequinocyl

- OH (US EPA, 2007; DPs: 330281and 337378 )

. S urface water estimated drinking water concentrations (EDWCs ) were generated for acequinocyl using the Pesticide Root Zone Model/Exposure Analysis M odeling System (PRZM/EXAMS) model

. The highest PRZM

- EXAMS surface water mo deling estimates were obtained for the Pennsylvania apple scenario for the acute value , and Pennsylvania tomato scenario for the chronic values

. The recommended EDWCs for the human health risk assessment, based on apples , pecans, and tomato uses, are provided in Table 1 . The EDWCs derived via Approach #1 represent upper bound values while those derived via Approach #2 represent the lower bound values

Acequinocyl and its major degradate , hydroxy- acequinocyl , were not monitored in surface and groundwater under the USGS’s National Water Quality Assessment (NAWQA) program. Although the fate and transport database is complete, most of the environmental fate studies submitted prior to the initial registration were classified ‘supplemental’ due to numerous deficiencies identified in the fate studies such as poor chromatographic separation of acequinocyl and R1, use of chloroform :methanol solvent system, lack of LOD and LOQ data, un

- eluted radioactive residues in the solid phase extraction process, and lack of storage stability data. These issues need to be addressed b y the registrant to upgrade the fate studies.

2. PROBLEM FORMULATION
2.1. Background The most recent regulatory actions for acequinocyl include the following:

• Section 3 Request for Uses of Acequinocyl (P.C. Code: 006329) on Greenhouse, Shade house, Ornamental, Floral, Foliage and Nursery Crop s. August 7, 2003 (US EPA 2003, D291707)

• Section 3 Request for Uses of Acequinocyl (P.C. Code: 006329) on Pome Fruits, Citrus, Almonds, Pistachios, Strawberries and Outdoor Ornamentals. February 3, 2004. (US EPA 2004, DP Barcodes: D285811, D286428, D289153, D290010, D287269, D290009, D291174)

• Ecological Risk Assessment for Use of Acequinocyl (PC 006329) on Grapes, Pome Fruits, Citrus, Nuts, and Outdoor Non

-Food Uses. August 17, 2007. (US EPA 2007, DP 337381, 330467, 330471)

• Tier II Drinking Water Assessment for Acequinocyl. June 27, 2007 (US EPA 2007, DP337221)
The previous PRZM

- EXAMS EDWC estimates were based on the Pennsylvania apple crop scenario. The 1

- in

- 10

- ye ar annual peak (acute) concentration of parent acequinocyl was 13.4 μg/L , the 1

- in

- 10

- ye ar annual daily mean (chronic

-non cancer) concentration was 2.7 3 μg/L , and the 30

-ye ar annual mean was 2.3 μg/L based on the Approach # 1. Based on Approach #2, the acute, chronic

-non cancer, and 30

- ye ar annual mean concentrations were 10.81 μg/L , 0.37 μg/L , and 0.2 μg/L , respectively, for acequinocyl and its R1 degradate

. The ground water EDWC for acequinocyl and acequinocyl

- OH in shallow ground water sources was 0.0036 μg/L for acequinocyl applied twice every 21 days regardless of the ty pe of model approach used

. These EDWC s from shallow ground water sources are expected remain the same for the proposed uses as acequinocyl proposed use rates are the same as the currently registered food use rates

. In the previous assessment, EFED recommended use of acequinocyl EDWCs derived using Approach #1, in the event that HED finds R1 is not of toxicological concern

.

2.2. Mode of Action Acequinocyl is a miticide. Its mode of action is mediated by both the parent chemical and its primary degradate, 2

- dodecyl

- 3

-hydroxy- 1,4

-napthoquinone (also referred to as R1, deacetyl ated acequinoc yl , acequinocyl

- OH, OH

-AKD 2023, or AKM

- 05) through the inhibition of electron transfer in mitochondria.
2.3. Use Characteristic s KANEMITE 15 SC is a miticide for the control of Citrus red mite ( Panonychus citri), European red mite ( Panonychus ulmi) , Pacific spider mite ( Tetranychus pacificus), Texas citrus mite ( Eutetranychus banskl) and Spruce spider mite ( Oligonychus ununquis), Strawberry spider mite ( Tetranychus turkestam ), Willamette spider mite ( Eotetranychus willamettel), Two spotted spider mite ( Tetran

ychus urticae and Tetranychus cinnabarinus), and Broad mite ( Polyphagotarsonamus latus). According to the registrant, when applied to the foliage , KANEMITE 15 SC provides quick knockdown and long residual control. Due to its unique mode of action, KANEMITE 15 SC is not expected to have cross

-resistance to existing miticides and is reportedly very

effective against various species of resistant and susceptible mites.
Acequinocyl initial food use registration was for pome fruits, citrus, almonds, pistachios , strawberries , and outdoor ornamentals (US EPA, 2004). Currently, the registrant proposed new uses for acequinocyl include fruiting vegetables (except field grown and greenhouse grown cucurbits) ( eggplant, groundcherry ( Physalis spp .), pepino, pepper (includes bell pepper, chili pepper, cooking pepper, pimento, sweet pepper, tomatillo, and tomato), okra, edible podded beans, and hops . The maximum application rates for the proposed uses are not to exceed 0.3 lb ai/acre for a single application rate, and 0. 6 lb ai/acre for a seasonal application rate, with a minimum reapplication interval of 21 days. The maximum proposed application rates are same as the application rates for currently registered acequinocyl agricultural uses. Table 2 summarizes the application rates and application methods for acequinocyl proposed and currently registered use s

## The product label use restrictions specify that the product is not to be applied via irrigation, via aerial application, or within 75 feet of aquatic areas . In addition, it is not intended for indoor residential use. Currently, the label includes the following surface water statement :
“ This product may

contaminate water through drift of spray in wind. This product has a potential for runoff for several days after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. A level, well maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential for contamination of water from rainfall

-runoff. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. Sound erosion control practices will reduce this product's contribution to surface water contamination.”
2.4. Conceptual Model
A. Risk Hy

pothesis
For acequinocyl , the following risk hy pothesis is being employed for this national

- scale drinking water assessment : Acequinocyl, when used in accordance with proposed labels, can result in off

-site movement of the compound product via runoff and spray drift, leading to human exposure to acequinocyl and its degradate acequinocyl

- OH (R1) through consumption of contaminated drinking water

. B. Conceptual M odel Submitted fate and transport data indicate that acequinocyl is highly reactive, with breakdown potentially occurring quickly via both photolys is and hydrolysis. Acequinocyl can reach surface

## 6

water via spray

drift and less likely

via runoff

. Once acequinocyl has entered surface water, it is not likely to persist as it will hydrolyz e to form hydroxy

- acequinocyl (also known as OH

- AKD 023, 2

-hydroxy

- 3

- dodecyl

- 1,4

-napthe lenedione (HDNQ), and R

- 1 )

. The source of the stressor considered herein is acequinocyl (PC Code 006329 ). The source and mechanism of release for the proposed new uses of acequinocyl are foliar ground application. The mechanisms of acequinocyl transport are spray drift (parent) and potentially surface water runoff (degradate)

. Leaching into groundwater is not expected to be a major contributor, based on submitted laboratory

studies , indicating that acequinocyl has very low mobility potential

. Surface water runoff from the areas of application is assumed to follow topography. Spray drif t will follow the wind directions. Potential emission of volatile compounds is not considered as a viable release mechanism for acequinocyl , since volatilization is not expected to be a significant route of dissipation for this chemical because of the l ow vapor pressure of the compound. These transport mechanisms (e.g. sources) are depicted in the conceptual model below (Figure 1 ) and result in the potential movement of acequinocyl and hydroxy

- acequinocyl into surface water, and less likely into ground water. In surface water, acequinocyl appears to be short lived to form hydroxyacequinocyl. Volatilization, crop uptake, and tile drainage are potential mechanisms of transport that are depicted in the model, but not considered in this assessment due to their low significance for acequinocyl transport.

Figure 1. C onceptual model for acequinocyl mechanism of release and transport into drinking water sources.

2.5. Analysis Plan
Two approaches were used in this drinking water assessment for the proposed acequinocyl uses to account for the deficiencies identified in the registrant

- submitted fate studies . In Approach # 1, acequinocyl was conservatively assumed to be stable to all routes of degradation to account for the uncertainties associated with the environmental fate data. In Approach #2, total (acequinocyl + acequinocyl

- OH) residues were modeled assuming that the R1 metabolite is of toxicological concern. In both approaches, surface water EDWCs were generated for acequinocyl using the PRZM/EXAM S model

. The previous PRZM

- EXAMS surface water modeling estimates were based on the Pennsylvania apple crop scenario. For this assessment , PA Apple and GA Pecan scenarios were re - evaluated with the use of updated Perl shell interface program, PE5.pl (November 15, 2006), according to the current modeling input parameter guidance (Version 2.1; US EPA, Oct. 22, 2009 )

. Additionally, seven scenarios were modeled for the proposed uses

. Fruiting vegetables were represented by Penns ylvania, California, and Fl orida tomato and Florida pepper scenarios, edible podded beans b y Michigan beans and Oregon snap beans scenarios, and hops were represented by Oregon hops scenario. Currently, EFED does not have an okra scenario ; therefore, Florida tomato and pepper scenarios were considered to be surrogate scenarios for the okra proposed uses. Okra can be grown throughout the Florida state, but commercial production is concentrated in the Dade County

area and bordering counties. In 2004, Florida okra production was estimated at 1,500 acres (Florida Crop Profile: http://www.ipmcenters.org/CropProfiles/docs/FLokra.pdf )

. Acequinocyl ground water EDWCs are the same as assessed in the previous drinking water assessment since the proposed application rates and intervals are the same as currently registered food uses

.

3. ANALYSIS
3.1. Fate and Transport Characterization Based on the environmental fate data reviewed for the initial registration that appeared to be of uncertain quality, acequinocyl appeared to undergo fairly rapid transformation in most aquatic and terrestrial environments. The chemical hydrolyz ed with a half

- life of a few hours to less than 2 days under neutral and alkaline pH conditions (MRID 45434908) . However, it was stable under acidic pH conditions. Photodegradation in water appeared to be the main route of degradation in aquatic environments , with half

- lives of less than 15 minutes in sterile lab and river water. Acequinocyl also appeared to undergo fast degradation in terrestrial environments. The half

- lives for aerobic biotransformation on soil were less than 2 days under laboratory conditions (MRID 45434911)

. Under field conditions, acequinocyl applied to bare plots dissipate d with half

- lives ranging from 2 hrs in California to 14 hours in New York (MRID 45651601)

. In contrast, the residue decline data submitted for the Magnitude of Residue studies on apples, pears, oranges, grapefruit, lemon and almonds indicated a mean half

- life of 20 days.

## 8

Acequinocyl presented very low mobility in soil. The soil adsorption Kd 

## for acequinocyl range d from 678 ml/g in sandy l oam soil to 1,620 ml/g in silty clay loam soil (MRID 45531902) based on a study with one test concentration as opposite of four test concentrations as Subdivision N guidelines specify

. In the field studies, the parent was not dete cted below 0

- 15 cm soil depth (MRID 45651601). The major transformation products detected in the field included R1 (2

- dodecyl

- 3

-hydroxy

- 1, 4

-napthoquinone) and AKM

- 18 [ 2

- (1,2

- dioxotetradecyl) benzoic acid]

. Based on acequinocyl bioconcentration factor in fish (BCF range d from 307 to 387 (MRID 45434923)) and its rather high octanol/water partition coefficient (Log Kow ≥ 6.2), acequinocyl can expect to bi oconcentrate in fish if found in water

. Since acequinocyl has low vapor pressure of 1.7 x 10 - 9 

## PA (at 25 o 

## C) and very low water solubility o f 0.006 mg/L , any losses due to volatilization are expected to be minimal. Further details on fate studies and other fate properties of acequinocyl can be accessed from the original risk assessment document (US EPA, 2004 )

. Table 3 provides summary of physical and chemical properties of acequinocyl. Table 1.1 of Appendix I provides a summary of acequinocyl major degradates and their maximum percent formation observed in the laboratory and field studies.

## 3.2. Drinking Water Exposure Modeling
3.2.1. Surface Water Modeling The Tier II drinking water assessment was performed using PRZM (v3.12.2; May 12, 2005)/EXAMS (v. 2.98.04.06; April 25, 2005) modeling with index reservoir (IR) scenari os and percent cropped area (PCA) adjustment factors. In performing the drinking water assessment for the proposed acequinocyl uses , two approaches were taken . In Approach # 1, acequinocyl was conservatively assumed to be stable to all routes of degradati on because of the uncertainties associated with the environmental fate data

. In Approach #2, total (acequinocyl + acequinocyl

OH) residues were modeled assuming that the R1 metabolite is of toxicological concern. All half

- lives used in this modeling appro ach were calculated based on the total (acequinocyl + R1) residues. Additionally, the adsorption coefficient (Kd

## ) for the metabolite R1 was used in the modeling as R1 is more mobile than acequinocyl.
Table 3 lists the input parameters used for the PRZM/EXAMS modeling of acequinocyl and the R1 degradate. Table 4 presents PRZM/EXAMS estimated drinking water concentrations from surface water sources for acequinocyl and the R1 degradate for proposed ( apples and pecans ) and registered ( fruiting vegetables, edible podded beans, okra, and hopes ) uses.

A

– A default PCA of 0.87 was applied 

## Regardless of the food crop use , a default PCA value of 0.87 was applied to EDWCs. Among all the registered and proposed new uses, the highest EDWCs from surface water sources were derived using Approach #1 for ground application of acequinocyl to PA apples scenario for the acute value , and Penns ylvania tomato scenario for the chronic values simulated at the maximum annual application rate of 0. 6 lb ai/acre. The acute EDWCs in surface water (1

- in

- 10 year annual peak concentration) reached a maximum of 12.2 μg/L (PA Apple) , the chronic non

- cancer EDWC (1

- in

- 10 year annual average concentration) is expected not to exceed 2.45 μg/L (PA Tomato) , and the cancer/chronic drinking water concentration (30

- ye ar annual average) is expected not to exceed 2.02 μg/L (PA Tomato) . The PRZM/EXAMS output files for selected modeled scenarios are provided in the Appendix II

. 3.2.2. Ground Water Modeling Estimated concentrations of acequinocyl total toxic residue s in drinking water from shallow ground water sources for the proposed uses are the same as for currently registered uses because the application rates and intervals are the same for both uses . Therefore, the estimated environmental concentrations are not expected to exceed 3.6 x 10 - 3 

## μg/L based on the maximum application rate of 0.6 lb ai/acre . This concentration can be considered as both the acute and chronic value. For details regarding SCI

- GROW modeling refer to the previous drinking water assessment (US EPA, 2007)

. 3.2.3. Assu mptions and Uncertainties The following uncer

tainties have been identified in the environmental fate properties and drinking water assessment for acequinocyl :

## 12

• Most of the environmental fate studies submitted prior to the initial registration were class ified ‘supplemental’ due to deficiencies identified in the fate studies such as poor chromatographic separation of acequinocyl and R1, use of chloroform : methanol solvent system, lack of LOD and LOQ data, un

- eluted radioactive residues in the solid phase extraction process, and lack of storage stability data.

• In PRZM/EXAMS modeling , Approach #1, acequinocyl was conservatively assumed to be stable to all routes of degradation to account for the uncertainties associated with the environmental fate data

. This approach generated conservative, upper bound, EDWCs for acequinocyl. Therefore, exposure to acequinocyl may be overestimated

.

• The impact of spray drift buffers was not considered in this drinking water assessment

. With a 75 ft. spray drift buffer (spray drift fraction = .006) , the ground application effective drift to a water body would be smaller than without the buffer (0.063). However, based on comparison of EDWCs (not corrected for PCA) derived for the PA Apples scenario with and without the 75 ft spray drift buffer, the impact of spray drift on the EDWCs is minimal

## • SCI

- GROW estimated the concentration of acequinocyl (Approach # 1) and total residue ( acequinocyl+R1 ; Approach #2 ) in shallow ground water sources to be <0.0036 μg/L

. The ground water EDWC s were obtained using the median Koc value of 37,550 ml/g for acequinocyl, and the median Koc value of 36,000 ml/g for the total (acequinocyl+R1) residues , which are greater than the Koc limit of 9,995 ml/g , and are beyond the scope of the regression data used in SCIGROW development. If there are concerns for such chemicals, a higher tier groundwater exposure assessment should be considered, regardless of the concentration returned b y SCI

- GROW.

• Two method validation studies (MRID 46182601 and 46182602) submitted by the registrant to determine the concentrations of acequinocyl and its metabolite(s) in soil and water extracts were reviewed b y the EPA’s Environmental Chemistry Laboratory. The registrant was informed of the suggested amendments and request for new calibration data in a memo date d 27 June, 2007. Recently, the registrant submitted the amended analytical method for determination of residues of acequinocyl and its major metabolite R1 (hydroxy- acequinocyl) in drinking water, ground water and surface water (MRID 48016602), and the amended analytical method for the determination of acequinocyl, hydroxy- acequinocyl, and AKM

- 18 in soil (MRID 48016601) . The Agency is in the process of reviewing thes e submitted studies.
3.3. Drinking Water Treatment No specific information was available for the behavior of acequinocyl during drinking water treatment.

4. DATA REQUIREMENTS Most of the environmental fate studies submitted prior to the initial registration were classified ‘supplemental’ due to deficiencies such as poor chromatogra phic separation of acequinocyl and R1, use of chloroform: methanol solvent system, lack of LOD and LOQ data, un

- eluted radioactive residues in the solid phase extraction process, and lack of storage stability data. These issues need to be addressed b y the registrant to upgrade the fate studies.
