Summaries of Petitions

Petitioner summaries of the pesticide petitions are printed below
as required by section 408(d)(3) of the FFDCA. The summaries of the
petitions were prepared by the petitioners and

[[Page 21675]]

represent the views of the petitioners. EPA is publishing the petition
summaries verbatim without editing them in any way. The petition
summary announces the availability of a description of the analytical
methods available to EPA for the detection and measurement of the
pesticide chemical residues or an explanation of why no such method is
needed.

Interregional Research Project Number 4 (IR-4)

PP 1E6304, 2E6357, 2E6364, 2E6373

EPA has received pesticide petitions 1E6304, 2E6357, 2E6364 and
2E6373, from the Interregional Research Project Number 4 (IR-4), 681
U.S. Highway #1 South, North Brunswick, NJ 08902-3390 proposing,
pursuant to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40
CFR 180.532 by establishing tolerances for residues of cyprodinil, [4-
cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine], in or on the following
raw agricultural commodities (RACs):
1. PP 1E6304 proposes a tolerance for caneberry subgroup at 10.0
parts per million (ppm).
2. PP 2E6357 proposes a tolerance for bushberry subgroup,
lingonberry, juneberry, and salal, at 3.0 ppm.
3. PP 2E6364 proposes a tolerance for watercress at 20 ppm.
4. PP 2E6373 proposes a tolerance for pistachio at 0.07 ppm.
Additional data may be needed before EPA rules on the petitions.
Syngenta Crop Protection, Inc., Greenboro, NC 27409, is the
manufacturer of the chemical pesticide, cyprodinil. Syngenta prepared
and submitted the following summary of information, data, and arguments
in support of the pesticide petitions. This summary does not
necessarily reflect the findings of EPA.

A. Residue Chemistry

1. Plant metabolism. The metabolism of cyprodinil is adequately
understood for the purpose of the proposed tolerances.
2. Analytical method. Syngenta has developed and validated
analytical methodology for enforcement purposes. This method (Syngenta
Crop Protection Method AG-631B) has passed an Agency petition method
validation for several commodities and is currently the enforcement
method for cyprodinil. An extensive data base of the method validation
data using this method on various crop commodities is available.
3. Magnitude of residues. Complete residue data for caneberry
subgroup, bushberry subgroup, lingonberry, juneberry, salal, pistachio,
and watercress have been submitted. The requested tolerances are
adequately supported.

B. Toxicological Profile

An assessment of toxic effects caused by cyprodinil is discussed in
Unit III. A. and Unit III. B. of the Federal Register dated June 22,
2001 (66 FR 33478).
1. Animal metabolism. The metabolism of cyprodinil in rats is
adequately understood.
2. Metabolite toxicology. The residues of concern for tolerance
setting purposes is the parent compound. Based on structural
similarities to genotoxic nucleotide analogs, there was concern that
the pryimidine metabolites (CGA-249287, NOA-422054) may be more toxic
than the parent compound. However, EPA's review indicates similar
results in an acute oral and mutagenicity studies with both the parent
compound and the CGA-249287 metabolite. EPA concluded that the toxicity
of the CGA-249287 and NOA-422054 metabolites is no greater than that of
the parent, conditional on submission and review of confirmatory data
of an acute oral toxicity study and bacterial reverse mutation assay
for the NOA-422054 metabolite. Although the metabolites CGA-232449 and
CGA-263208 were determined to be of potential toxicological concern,
they are not expected to be more toxic than cyprodinil per se.
3. Endocrine disruption. Cyprodinil does not belong to a class of
chemicals known or suspected of having adverse effects on the endocrine
system. Developmental toxicity studies in rats and rabbits and a
reproduction study in rats gave no indication that cyprodinil might
have any effects on endocrine function related to development and
reproduction. The chronic studies also showed no evidence of a long-
term effect related to the endocrine system.

C. Aggregate Exposure

1. Dietary exposure. Permanent tolerances have been established (40
CFR 180.532(a)) for the residues of cyprodinil, in or on a variety of
RACs. Tolerance are established on grape at 2.0 ppm, grape, raisin at
3.0 ppm; onion, dry bulb at 0.6 ppm, onion green at 4.0 ppm; stone
fruit group at 2.0 ppm, pome fruit group at 0.1 ppm, apple, wet pomace
at 0.15 ppm; almond nutmeat at 0.02 ppm and almond hulls at 0.05 ppm.
Time-limited tolerances under section 18 of Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA) (emergency exemption) have been
established under 180.532(b) for caneberry subgroup at 10.0 ppm, and
strawberry at 5.0 ppm. Tolerances values proposed in this submission
are: Caneberry subgroup (10.0 ppm); pistachio (0.07 ppm); watercress
(20 ppm); bushberry subgroup (3.0 ppm), lingonberry (3.0 ppm),
juneberry (3.0 ppm) and salal (3.0 ppm).
a. Food. The dietary exposure evaluation was made using the dietary
exposure evaluation model (DEEM\tm\, version 7.76) from Novigen
Sciences, Inc. DEEM default processing factors were used along with
United States Department of Agriculture (USDA) continuing survey of
food intake by individuals (CSFII) with the 1994-1996 consumption data
base and the supplemental CSFII children's survey (1998) consumption
data base. DEEM inputs for all currently registered uses, and proposed
uses listed above. Secondary residues in animal commodities were not
considered in this evaluation since calculations showed that residue
transfers from feed items to livestock and milk were minimal and
resulted in negligible exposures.
i. Acute exposure. Acute dietary risk assessments are performed for
a food-use pesticide if a toxicological study has indicated the
possibility of an effect of concern occurring as a result of a 1-day or
single exposure. EPA has not conducted an acute dietary risk assessment
since no toxicological endpoint of concern was identified during the
review of the available data.
ii. Chronic exposure. This chronic assessment utilized established
tolerance values for the current uses and proposed tolerance values for
the added proposed uses. This assessment assumes 100% crop treated for
all commodities. The chronic population adjusted dose (cPAD) for
cyprodinil is 0.03 milligram/kilogram (mg/kg) body weight/day (bwt/day)
and is based on a chronic rat study with a no observed adverse effect
level (NOAEL) of 2.7 mg/kg bwt/day and a uncertainty factor (UF) of
100X. No additional Food Quality Protection Act (FQPA) safety factor
was applied. For the purpose of aggregate assessment, the exposure
values were expressed in terms of margin of exposure (MOE) which was
calculated by dividing the NOAEL by the exposure for each population
subgroup. The benchmark MOE for this assessment is 100. Results from
the cPAD based risk analysis showed that there were acceptable safety
margins with respect to chronic exposures incurred by the dietary
consumption of cyprodinil-treated commodities. Chronic exposures to the
U.S. population (48 states, all seasons) resulted in a MOE of 1,274
(7.1% of the total cPAD of 0.03 mg/kg bwt/day). The most sensitive
subpopulation in the

[[Page 21676]]

chronic assessment was children (1 to 6 years) with a MOE of 354 (25.5%
of the cPAD). The results of the chronic dietary risk assessment are
presented in Table 1.
b. Drinking water exposure. Estimated environmental concentrations
(EEC's) of cyprodinil in drinking water were determined for the highest
use rate of cyprodinil, which is almond. Screening concentration in
ground water (SCI-GROW) (Version 2.1) was used to determine acute and
chronic EECs in ground water. First (Version 1.0) was used to determine
acute and chronic EECs in surface water. Based on model outputs, the
EECs of cyprodinil are 0.0056 parts per billion (ppb) for acute and
chronic exposure to ground water and 35 ppb and 1 ppb for acute and
chronic exposure, respectively, to surface water. Chronic drinking
water levels of comparison (DWLOC) were calculated based on a cPAD of
0.03 mg/kg/day. For the chronic assessment, children (1 to 6 years)
subpopulation generated the lowest chronic DWLOC of approximately 224
ppb. This gave a corresponding MOE value of 27,000. The chronic DWLOC
of 224 ppb is considerably higher than the chronic EEC of 1 ppb and the
MOE far exceeds the benchmark MOE of 100. The results for the U.S.
population and the most sensitive subpopulation are presented in Table
1.
2. Non-dietary exposure. Cyprodinil is not registered for use on
any sites that would result in residential exposure. Therefore, the
aggregate risk is the sum of the risk from food and water, which do not
exceed the Agency's level of concern.
3. Chronic aggregate exposure. Using the total MOE equation for the
determination of aggregate exposure (food and drinking water only),
resulted in an aggregate MOE_T of 342 for the most sensitive
subpopulation, children (1 to 6 years). Table 1 summarizes the
aggregate chronic exposure (food and drinking water only) for
cyprodinil.

\D\cPAD = 0.03 mg/kg body weight/day

\E\MOE_T = 1/((1/MOE_food)+(1/MOE_d.water))

D. Cumulative Effects

Cumulative exposure to substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) requires that, when considering
whether to establish, modify, or revoke a tolerance, the Agency
consider ``available information'' concerning the cumulative effects of
a particular pesticide's residues and ``other substances that have a
common mechanism of toxicity.'' EPA does not have, at this time,
available data to determine whether cyprodinil has a common mechanism
of toxicity with other substances or how to include this pesticide in a
cumulative risk assessment. Unlike other pesticides for which EPA has
followed a cumulative risk approach based on a common mechanism of
toxicity, cyprodinil does not appear to produce a toxic metabolite
produced by other substances. For the purposes of this tolerance
action, therefore, EPA has not assumed that cyprodinil has a common
mechanism of toxicity with other substances.

E. Safety Determination

1. U.S. population. The chronic dietary exposure analysis showed
that exposure from the proposed new tolerances for the general U.S.
population would be 7.1% of the cPAD.
2. Infants and children. The chronic dietary exposure analysis
showed that exposure from the proposed new tolerances for children 1 to
6 years old (the subgroup with the highest exposure) would be 25.5% of
the cPAD. Therefore, the estimates of dietary exposure clearly indicate
adequate safety margins for the overall U.S. population.

F. International Tolerances

There are no Codex maximum residue level's established for
cyprodinil.
