petitions. This notice includes a summary of the petitions prepared by

[[Page 19531]]

Syngenta Crop Protection, Inc., Greensboro, NC 27409.

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 method validation data 
using this method on various crop commodities is available.
    3. Magnitude of residues. Complete residue data to support the 
requested tolerances for almond, hulls, Brassica, head and stem 
(Subgroup 5A), Brassica, leafy greens (Subgroup 5B), turnip, greens, 
herbs (Subgroup 19A), and lychee, longan, rambutan, pulasan, and 
Spanish lime 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) (FRL-6778-7).
    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 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, 
there 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. A Tier III acute and chronic dietary exposure 
evaluation was made using the Dietary Exposure Evaluation Model 
(DEEMTM), version 7.76 from exponent. All consumption data 
for these assessments were taken from the USDA's Continuing Survey of 
Food Intake by Individuals (CSFII) with the 1994-96 consumption data 
base and the Supplemental CSFII children's survey (1998) consumption 
data base. These exposure assessments included all registered uses and 
pending uses on watercress, bushberries, caneberries, juneberries, 
ligonberries, pistachios, and salal.
    i. Food--a. 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.
    b. Chronic exposure. Percent of crop treated values were estimated 
based upon economic, pest and competitive pressures. The values used in 
these assessments were: (Almonds, pome fruits, stone fruits and 
grapes), 100%; onions 9%; strawberries 42%; watercress, 95%; berries, 
13%; pistachios, herbs, 80%; crop group 5A and 5B, carrots, turnip, 
greens, lychee, longan and Spanish lime, 10%.
    ii. Drinking water. Estimated Environmental Concentrations (EECs) 
of cyprodinil in drinking water were determined by EPA. EPA groundwater 
model Screening Concentration in Groundwater (SCI-GROW) was used to 
determine acute and chronic estimated environmental concentrations in 
ground water and the Agency's surface water model, EPA's pesticide root 
zone model/exposure analysis modeling system (PRZM/EXAMS) was used to 
determine acute and chronic EECs estimated environmental concentrations 
in surface water. Based on the model outputs, the EEC cyprodinil are 
0.04 parts per billion (ppb) for acute and chronic exposure to ground 
water and 32 ppb and 6 ppb for acute and chronic exposure, 
respectively, to surface water.
    2. Non-dietary exposure. There is a potential residential post-
application exposure to adults and children entering residential areas 
treated with cyprodinil. Since the Agency did not select a short-term 
endpoint for dermal exposure, only intermediate dermal exposures were 
considered. Based on the residential use pattern, no long-term post-
application residential exposure is expected.

D. Cumulative Effects

     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. For the purposes of this tolerance action, 
EPA has not assumed that cyprodinil has a common mechanism of toxicity 
with other substances.

E. Safety Determination

     The chronic dietary exposure analysis (food only) showed that 
exposure from all established and proposed cyprodinil uses would be 
7.48% of the chronic reference dose (cRfD) for the most sensitive 
subpopulation, children 1-2 years old. EPA has determined that reliable 
data support using the standard margin of exposure (MOE) and 
uncertainty factor (100 for combined interspecies and intraspecies 
variability) for cyprodinil and that an additional safety factor of 10 
is not necessary to be protective of infants and children.
     Acute Drinking Water Levels of Comparison (DWLOC) were calculated 
based on an acute populated adjusted dose (aPAD) of 1.5 milligrams/
kilogram/day. For the acute assessment, the females (13-50 years) 
subpopulation generated an acute DWLOC of approximately 44,600 ppb. The 
acute EEC of 32 ppb is considerably less than 44,600 ppb. For the 
chronic assessment, the children 1-2 years old subpopulation generated 
the lowest chronic DWLOC of approximately 280 ppb. Thus, the chronic 
DWLOC of 280 ppb is considerably higher than the chronic EEC of 6 ppb.
     Syngenta has considered the potential aggregate exposure from 
food, water and non-occupational exposure routes and concluded that 
aggregate exposure is not expected to exceed 100% of the chronic 
reference dose and that there is a reasonable certainty that no harm 
will result to infants and children from the aggregate exposure to 
cyprodinil.

F. International Tolerances

     There are no Codex maximum residue levels established for 
cyprodinil.
