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 Start Printed Page 21675represent 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 (DEEMtm, 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 Start Printed Page 21676chronic 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 MOET 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.

C Benchmark MOE = 100
D cPAD = 0.03 mg/kg body weight/day
E MOET = 1/((1/MOEfood)+(1/MOEd.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.
