EXECUTIVE SUMMARY

The Environmental Fate and Effects Division (EFED) conducted a Tier II
screening-level drinking water assessment for the proposed new use of
the chemical buprofezin
[E,Z-2-tert-butylimino-3-isopropyl-5-phenyl-1,3,5-thiadiazin-4-one; CAS#
69327-76-0; PC Code 103801].  The Agency is considering buprofezin for
Section 3, New Use registration as an insecticide on olives,
strawberries, low-growing berries, and leafy vegetables.  Buprofezin is
an insect growth regulator, used to control white flies, leafhoppers,
scales, mealybugs, plant hoppers and related species.  Previously, EFED
conducted surface and ground water assessments for stone fruit group
(D321843); papayas and mangoes (D321846); almonds, bananas, citrus
group, cotton, grapes, and tomatoes (D271561); and melons, cucumbers,
pumpkins, squash, and lettuce (D244351).

Buprofezin is applied by ground or aerial spray at maximum single
application rates from 0.38 to 2.01 lb a.i./A and maximum seasonal
application rates of 0.76 to 4.02 lb a.i./A.  The assessment considers
the maximum proposed application rates for each new use as well as for
citrus, the currently registered use with the highest estimated
exposure.  The recommended estimated drinking water concentrations
(EDWCs) of buprofezin in surface water and ground water for the human
health risk assessment are summarized in Table 1.  Estimates are for
parent only as there were no degradates of concern for dietary exposure.
 The buprofezin concentrations in surface water were simulated in an
Index Reservoir, with 30 years of scenario specific weather data, using
the linked PRZM (v3.12.2, May 12, 2005) and EXAMS (v2.98.04.06, April
25, 2005) models with a national default PCA of 0.87 for all crops. 
Surface water exposure from use on cranberries was estimated using a
modification of the Tier I Rice Model.  The maximum acute and chronic
surface water EDWCs resulted from use on citrus.  Groundwater
concentrations were estimated using the SCI-GROW model.  SCI-GROW
represents a site vulnerable to ground-water contamination but is not
scenario specific, so the highest estimated exposures result from all
crops with the highest annual application rates, including olives and
citrus.  No monitoring data for buprofezin were available and so this
water resource assessment is based solely on model-estimated exposure
concentrations.

PROBLEM FORMULATION

	This is a Tier II drinking water assessment (DWA) that uses modeling
and available monitoring data to estimate the groundwater and surface
water concentrations of pesticides in drinking water source water
(pre-treatment) resulting from pesticide use on sites that are
vulnerable.  

While Tier I DWAs are designed to screen out chemicals with low
potential risk for posing a drinking water concern, the Tier II
assessment provides more site-specific, refined modeling estimates of
pesticide exposure by using additional environmental fate parameters,
specific soil data, weather information, and management practices to
estimate daily concentrations of pesticides for an extended period of
time (up to 30 years).  This Tier II surface water assessment reflects
application of buprofezin at maximum label rates and with scenarios
intended to be representative of environments that are more vulnerable
to runoff and leaching than most where registered crops may be grown.

Use Characterization

Buprofezin is an insect growth regulator which acts as a chitin
biosynthesis inhibitor.  It is currently registered as an insecticide
for control of whiteflies, mealybugs, leafhoppers, and scales on various
field crops, vegetables, fruits, orchards, and ornamentals.  It causes
nymphs to die at molting stage, suppresses oviposition of adults, and
reduces viability of eggs, therefore reducing the population of nymphs
and adults in the next generation, and interrupting the development
cycle of the insects.  

	The active ingredient is applied through ground or aerial spray. 
End-use products are a soluble concentrate formulation, Buprofezin 40SC
(3.6 lb a.i./gal, 40% a.i., Reg. No. 71711-20), and a dry flowable
formulation, Applaud 70DF (0.7 lb a.i./lb product, 70% a.i., Reg. No.
71711-21).  Proposed new uses are on olives, strawberries, low-growing
berries (bearberry, bilberry, lowbush blueberry, cloudberry, cranberry,
lingonberry, muntries and partridge berries), and leafy vegetables
(amaranth, arugula, chervil, chrysanthemum, corn salad, cress,
dandelion, dock, endive, head and leaf lettuce, orach, parsley,
purslane, radicchio, spinach, cardoon, celery, celtuce, fennel, rhubarb,
swiss chard).  

	Application information for all uses is presented in Table A1 in
Appendix A.  Buprofezin can be applied any time during the growing
season, depending on pest pressure.  For new uses, the proposed label
for olives allows two applications per year of Applaud 70DF, each at 1.5
to 2.0 lb ai/A with a 50 day application interval.  Strawberries,
low-growing berries, and leafy vegetables are treated with Buprofezin
40SC at a recommended single application rate of 0.25 to 0.38 lb a.i./A
with two applications per crop cycle.  For strawberries and low-growing
berries, the minimum application interval is 10 days, and for leafy
vegetables, it is 7 days.  Use on leafy vegetables is limited to four
applications per year.  Buprofezin is currently registered for use on
cotton, cucurbits, snap beans, tomatoes, ornamental plants, almonds,
pistachio, apples, bananas, citrus, grapes, peaches, pears, and multiple
tropical fruits.  Of all uses, the maximum labeled application rate is 2
applications per season of 2.01 lb a.i./A, allowed for citrus, peaches,
pears, and olives, with different minimum application intervals (60
days, 14 days, 7 days, and 50 days, respectively).  For the purposes of
assessing drinking water risk, estimated concentrations are based on the
use with the highest potential exposure, so proposed uses in this
assessment are considered along with use on citrus, which represents the
highest potential exposure from currently registered uses.  The maximum
use patterns that were considered in this assessment are summarized in
Table 2.  There is some uncertainty in these rates because many of them
are reported as rates per crop cycle or per season, rather than as rates
per year, so annual rates depend on the number of crop cycles per year.

Figure 1 presents the national usage pattern of buprofezin in 2002
(USGS, 2007).  At that time, cotton (41%) and grapes (36%) were the
primary uses, followed by citrus, tomatoes, and melons, all at ≤ 10%
of the national use.  Florida, California, and Arizona were the only
areas where use was identified.

Conceptual Model

Buprofezin may reach surface sources of drinking water via spray drift
and runoff, and groundwater via leaching.  Buprofezin is moderately
persistent in aerobic soils (t1/2 =  37-101 days) but it has low
mobility (Kd = 10-277 mL/g) and is likely to partition to soil, which
should limit runoff and leaching.  Once buprofezin has entered surface
water, it is stable to hydrolysis in alkaline and neutral conditions. 
In acidic environments buprofezin can hydrolyze slowly (t1/2 =  58
days), and in near surface clear waters it can degrade through aquatic
photolysis (t1/2 =  38 days).  Buprofezin that reaches groundwater may
persist due to its stability to hydrolysis in most conditions.

Figure 1.  National Usage of Buprofezin in 2002 (USGS, 2007).

ANALYSIS

Environmental Fate and Transport Characterization

	The environmental fate database for buprofezin is largely complete. 
The following discussion is drawn from the original new chemical review
(6/7/2000, D244352) and the reregistration eligibility document
(5/18/2001, D271561).  Summaries of all environmental fate studies can
be found in the new chemical review; no new data have been received
since then.  Physical/chemical and environmental fate and transport
properties are listed in Table 3.

	Buprofezin does not hydrolyze in neutral or alkaline (pH ≥ 7)
conditions, but will degrade slowly under acidic (pH 5) conditions (t1/2
= 58 days).  Buprofezin may undergo photolytic degradation in water
(t1/2 = 38 days) and is stable to photolysis in soil. The major route of
dissipation is believed to be metabolism in soils: in microbially active
soil systems, buprofezin is moderately persistent with linear
first-order half-lives of 36.5 and 101 days for a sandy loam and sandy
clay loam soil, respectively.  In the field, buprofezin dissipated at
relatively consistent rates, with half lives of 37 days in a sandy loam
(Fresno, CA) and 38 days in a loamy sand (Pikeville, NC).

a Reported in earlier documents as 39 days.  The study summary, however,
states that observed dissipation was the same in dark controls and so
did not result from photolysis.

	The laboratory determined Kd values range from 11 mL/g in sand to 277
mL/g in clay loam textured soil.  This indicates that sorption to soil
could be significant. Therefore, low  leaching potential of buprofezin
is expected in the field, as well as low runoff to surface water, as
buprofezin will likely remain bound to soils, then mineralize to CO2.
Consistent with these results, there is no evidence of buprofezin
leaching in the terrestrial field dissipation studies. Neither
buprofezin or its degradates were detected below 7.5 cm.

	Volatility studies were not reported.  Some volatilization was observed
in the soil photolysis study, when buprofezin was applied to a thin,
moist soil layer, irradiated, and continuously purged with air, but
under the conditions of the aerobic soil metabolism study,
volatilization was not detected. EFED believes that buprofezin physical
properties (molecular weight of 305 and melting point of 105 °C)
support the aerobic soil metabolism study findings that volatilization
from soil is not significant under field conditions. For volatility in
water, the Henry's Law constant (6.73 x 10-6 atm-m3/mole) leads to a
classification of buprofezin as a semi-volatile compound (Lyman, 1990). 
Therefore volatilization of buprofezin may be expected in shallow,
clear, moving waters. Loss to the air in deeper, cloudy water may be
much less significant.

	Three major degradates were observed in the laboratory aqueous studies,
BF-12 ( N-(l-methylethy1)-N’-phenylurea) and BF-25 (N-[[(1,
l-dimethylethyl)amino]thioxomethyl]-N-(1-methyleyl)-N’-phenylea;
thiobiuret), formed through hydrolysis at pH 5, and BF-21
(N-phenylformamide), formed through aquatic photolysis.  See Appendix B
for structures.  No major degradate except for CO2 was detected in the
laboratory soil studies, although BF-12 was seen as a minor degradate
under aerobic conditions. This suggests that it is unlikely that any
buprofezin degradates found in the laboratory studies will form or
accumulate in significant quantities in the field. Indeed, when analyzed
for in the terrestrial field samples, BF-12 was detected at maximum of
less than 10% of parent and only in the top soil layer (0-12 inches).

Drinking Water Exposure Modeling

Estimated drinking water concentrations (EDWCs) were generated using
EFED’s standard suite of models.  The proposed new uses on olives,
strawberries, low-growing berries, and leafy vegetables were considered
along with citrus, the currently registered use pattern with the highest
estimated drinking water exposure.  Models and additional information
about model assumptions and uncertainties, input guidance, and scenario
metadata are available at the EPA’s water modeling website,
http://www.epa.gov/oppefed1/models/water/.

Models

	Pesticide Root Zone Model (PRZM v3.12.2, May 12, 2005) and Exposure
Analysis Modeling System (EXAMS v2.98.04.06, April 25, 2005) are
simulation models coupled with the input shell pe5.pl (Nov. 16, 2006) to
generate EDWCs of buprofezin residues that may occur in surface water
used as drinking water.  The PRZM model simulates pesticide movement and
transformation on and across the agricultural field resulting from crop
applications.  The EXAMS model simulates pesticide loading via runoff,
erosion, and spray drift assuming a standard watershed of 172.8 ha that
drains into an adjacent standard drinking water index reservoir of 5.26
ha, an average depth of 2.74 m.  Percent Cropped Areas (PCA) that
account for the maximum area within a watershed that may be planted with
the modeled crop are applied to concentrations predicted by PRZM/EXAMS.

	PRZM/EXAMS does not adequately represent potential exposure from use on
cranberries, because water management on cranberry crops includes
periodic flooding of cranberry beds for harvest and flood protection, a
practice which leads to potential routes of drinking water exposure that
are not represented in PRZM/EXAMS.  Surface water exposure from use on
cranberries was therefore modeled using a modification of the Tier I
Rice Model v1.0.  The Rice Model is not designed for modeling cranberry
uses, but of the available models, it is the most representative of
conditions in a cranberry bog.  The Rice Model takes the total annual
application to a rice paddy and calculates partitioning of the pesticide
between the water and the paddy sediment according to a linear or Kd
partitioning model.  Concentrations are assumed to immediately and
evenly distribute throughout the rice paddy water.  Dissipation
processes, such as degradation, volatilization, and potential dilution
with uncontaminated water outside the paddy are not accounted for by the
model.  Movement of pesticide on suspended sediment is not considered. 
The single exposure estimate produced with the Rice Model is used as an
acute and a chronic screening exposure estimate that is expected to
represent high-end exposure in released flood water.  The EDWC produced
by the Rice Model is not adjusted by an agricultural PCA value because
these values may not apply to semi-aquatic agriculture.  PCA values were
designed for exposure estimates in runoff from terrestrial crops, not
for exposure estimates in tailwater from flooded crops.  For the
cranberry use, the model is modified to account for aerobic soil
metabolism that occurs between application and flooding.  Partitioning
to bog water is then calculated for the residual compound only. 
Additionally, the model is adjusted to assume a flood depth of 18
inches, rather than 4 inches (DP Barcode D339984)..  EFED assumes that
in drinking water sources, dilution over time is sufficient to reduce
the concentrations of pesticides, making EDWCs from the Rice Model
inappropriate for estimating chronic exposure from use on cranberries.

	Screening Concentration in Ground Water (SCI-GROW v2.3, Jul. 29, 2003)
is a regression model used as a screening tool to estimate pesticide
concentrations found in ground water used as drinking water.  SCI-GROW
was developed by fitting a linear model to ground water concentrations
with the Relative Index of Leaching Potential (RILP) as the independent
variable.  Ground water concentrations were taken from 90-day average
high concentrations from Prospective Ground Water studies.  The RILP is
a function of aerobic soil metabolism and the soil-water partition
coefficient.  The output of SCI-GROW represents the concentrations of
buprofezin residue that might be expected in shallow unconfined aquifers
under sandy soils, which is representative of the ground water most
vulnerable to pesticide contamination and likely to serve as a drinking
water source.

  

Modeling Approach and Input Parameters

	Input values were chosen in accordance with current input parameter
guidance.  Table 4 lists the PRZM/EXAMS surface water modeling inputs
which are not crop-specific; crop-specific inputs will be discussed
further below.  Tables 5 and 6 list inputs for SCIGROW groundwater
modeling and for Rice Model surface water modeling.  These models are
not environment or crop-specific and so all inputs are included here. 
Exposure was estimated for the parent compound only, since the Health
Effects Division’s (HED) Metabolism Assessment Review Committee (MARC)
determined that there were no degradates of concern for dietary exposure
(D264546; T. Bloem, 4/20/2000).  The upper 90% confidence bound on the
mean was selected for the aerobic soil metabolism half-life (168 d) for
surface water and the median value (69 d) was used for groundwater
modeling, as per current input parameter guidance for these models. 
Hydrolysis was input as stable, to represent the behavior at pH 7. 
Since there are no submitted data for aqueous metabolism and hydrolysis
is not a dominant process, the aerobic aquatic half-life was assumed to
be twice the aerobic soil half-life.  For surface water, because
sorption was not found to correlate with organic matter content, Kd was
used, the lowest non-sand value (69 mL/g) in PRZM/EXAMS and the mean
value (98 mL/g) in the Rice Model.  For groundwater, the median Koc
(2791 mL/goc) value was used.  The default agricultural PCA of 0.87 was
used for all crops because they are not confined to specific regions of
the U.S.  Actual fractions of cropped areas could be less for some crops
and in some areas of the country.

Inputs and scenarios used in PRZM/EXAMS to represent environmental
conditions and crop management practices are presented in Table 7. 
Currently approved PRZM scenarios were used in surface water modeling. 
Nationally representative crop-specific scenarios were available to
simulate the uses on strawberries and on olives.  The California olive
scenario is considered to be nationally representative of the olive use
because 99% of all olives are grown in California.  For strawberries,
the Florida and California strawberry scenarios were designed to
represent an upper bound of vulnerable environments nationally.  For the
leafy vegetable and low-growing berry (excluding cranberry) categories,
multiple scenarios were used to represent the broad range of crops and
environments included in these groups.  In the leafy vegetable category,
the California lettuce scenario was used to represent head and leaf
lettuce and similar crops, for which this scenario was designed. 
Vegetable crops like celery and rhubarb were simulated using the Florida
tomato and pepper scenarios, designed for general vegetables nationally,
and the California row crop scenario, a regional vegetable scenario. 
There are currently no scenarios available to represent berries
nationally; the Oregon berry scenario represents the Pacific Northwest
region.  Surrogate scenarios were used to represent other berry-growing
areas, including California winegrape, Georgia peach, and Michigan
cherries.  Metadata for all scenarios are available at   HYPERLINK
"http://www.epa.gov/oppefed1/models/water/metadata.htm" 
http://www.epa.gov/oppefed1/models/water/metadata.htm .  

Application methods and rates were obtained from the proposed labels
(EPA Reg. No. 71711-20 and -21).  Except for some uses, buprofezin
labels allow both ground and aerial applications.  Modeling assumed
aerial application for all uses except for those which specified ground
application only.  There is some uncertainty in the number of
applications; the maximum number of applications per year is stated only
for olives and leafy vegetables.  For other uses, rates are reported
seasonally, so annual rates depend on the number of growing seasons per
year.  A single growing season was assumed for berries and for citrus. 
Two growing seasons with a 30 day interval were modeled for
strawberries, which can have three or four crops from a single planting
based on a 30 day cycle.  For leafy vegetables, two growing seasons were
modeled, as allowed by the label.  The interval between seasons was
modeled as 80 days, based on the typical time between planting and
harvest.  Application timing of buprofezin is related to various pest
pressures.  The insects targeted by this active ingredient are present
on leaves, so application windows were assumed to be between crop
emergence and crop harvest, as designated in each scenario.  In order to
simulate runoff conservatively, application dates were selected based on
the periods within this window which had the highest precipitation local
to the scenario site.

Modeling Results

	Maximum proposed new use patterns were modeled for surface water and
ground water exposure estimates, as described above.  Citrus, the
currently registered use with the highest exposure potential, was
modeled as well.  Although EDWCs for citrus have been reported in past
assessments, the use was modeled again so that modeling methods would be
consistent across compared uses.   Surface water EDWCs for all modeled
uses are listed below in Table 8.  EDWCs ranged from 4.5 to 57.4 ppb for
acute exposure in surface water and from 1.5 to 12.5 ppb for chronic
exposure.  For both acute and chronic exposure, citrus remained the use
pattern yielding the maximum surface water EDWCs for use in drinking
water exposure estimation.  Groundwater EDWCs do not reflect
site-specific environments or agricultural practices other than
application rates, so all uses with the maximum application rate share
the highest values.  The proposed use on olives, as well as currently
registered uses on citrus, peaches, and pears, all lead to acute and
chronic groundwater EDWCs of 0.09 ppb.  Model input/output data for
these estimates are attached in Appendix C.

Monitoring Data

	No monitoring data were found for buprofezin.  Sources checked include
the U.S Geological Service National Water Quality Assessment database
(NAWQA, 2007), the USGS/EPA Reservoir Monitoring Program (Blomquist et
al., 2001), the California Department of Pesticide Regulation Surface
Water Database (DPR, 2006) and the National Stream Quality Accounting
Network database (NASQAN, 2006).

Drinking Water Treatment

	There is no available information on the drinking water treatment
effects on buprofezin.

4.	CHARACTERIZATION

	The estimated concentrations provided in this assessment were generated
from Tier I (groundwater) and Tier II (surface water) models and are
conservative estimates of buprofezin concentrations in untreated
drinking water.  They represent the maximum use patterns on current and
proposed uses.  None of the EDWCs determined for the newly assessed uses
exceeded those for the previously registered use on citrus, updated
using current models and guidance.

	Tier I modeling is based on sites that are highly vulnerable to runoff
or leaching and includes protective assumptions about environmental
conditions and fate properties.  The presented Tier II modeling uses
crop-specific scenarios to represent vulnerable sites in areas where the
treated crops are grown, but otherwise uses the same protective
assumptions about fate properties and agricultural practices.  Tier II
modeling is more refined than Tier I modeling, but Tier II estimated
exposure values are still screens, although finer screens than Tier I
models.

 For some uses, labels only specify seasonal application rates, while
others specify annual rates as well.  Unless noted, application rate is
per season; multiple seasons per year, then, would lead to higher annual
application rates.

 Cucumbers, melons (cataloupe, honeydew, watermelon, muskmelons),
pumpkins, squash.
