Summary of Petition

The petitioner summary of the pesticide petitions is printed below as required by FFDCA section 408(d)(3). The summary of the petitions was prepared by the petitioner and represents the view of the petitioner. 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)

3E6551, 3E6639, 3E6701, and 3E6803

EPA has received pesticide petitions (3E6551, 3E6639, 3E6701, and 3E6803) from IR-4, 681 U.S. Highway #1 South, North Brunswick, NJ 08902-3390 proposing, pursuant to section 408(d) of FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part 180.516 by establishing tolerances for residues of fludioxonil, 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-H-pyrrole-3-carbonitrile in or on the following raw agricultural commodities:

1. PP 3E6551 proposes a tolerance for kiwifruit at 20 parts per million (ppm).

2. PP 3E6639 proposes a tolerance for leafy greens subgroup 4A, except spinach at 30 ppm.

3. PP 3E6701 proposes tolerances bean, dry and bean, succulent at 0.4 ppm.

4. PP 3E6742 proposes tolerances for fruit, pome, group 11 at 5.0 ppm, yam at 8.0 ppm, and melon subgroup 9A at 0.03 ppm.

5. PP 3E6803 proposes tolerances for citrus, crop group 10 at 10 ppm; citrus, dried pulp at 20 ppm, citrus, oil at 500 ppm, and pomegranate at 2.0 ppm.

EPA has determined that the petitions contain data or information regarding the elements set forth in section 408(d)(2) of FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data supports granting of the petitions. Additional data may be needed before EPA rules on the petitions. This notice includes a summary of petitions prepared by Syngenta Crop Protection, Inc., Greensboro, NC 27409.

A. Residue Chemistry

1. Plant metabolism. The metabolism of fludioxonil 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-597B) has passed an Agency petition method validation for several commodities, and is currently the enforcement method for fludioxonil. This method has also been forwarded to the Food and Drug Administration for inclusion into PAM II. An extensive database of method validation data using this method on various crop commodities is available.

3. Magnitude of residues. Complete residue data for the crops requested in this filing have been submitted. The requested tolerances are adequately supported.

B. Toxicological Profile

An assessment of toxic effects caused by fludioxonil is discussed in Unit III. A. and Unit III. B. of the Federal Register dated August 2, 2002 (67 FR 50354) (FRL-7188-7).

1. Animal metabolism. The metabolism of fludioxonil in rats is adequately understood.

2. Metabolite toxicology. The residues of concern for tolerance setting purposes is the parent compound. Consequently, there is no additional concern for toxicity of metabolites.

3. Endocrine disruption. Fludioxonil does not belong to a class of chemicals known for having adverse effects on the endocrine system. No estrogenic effects have been observed in the various short- and long-term studies conducted with various mammalian species.

C. Aggregate Exposure

1. Dietary exposure—i. Food. Tier III acute and chronic dietary exposure evaluations were made using the Dietary Exposure Evaluation Model (DEEMTM), version 7.87 from Exponent. Empirically derived processing factors for apple juice (0.09X), apple pomace (6.77X) and grape juice (0.36X) were used in these assessments. The apple juice processing factor was used as a surrogate for pear juice. All other processing factors used Start Printed Page 12683the DEEMTM defaults. All consumption data for these assessments was taken from the USDA's Continuing Survey of Food Intake by individuals (CSFII) with the 1994-96 consumption database and the Supplemental CSFII children's survey (1998) consumption database. These exposure assessments included all registered uses and pending uses on leafy greens subgroup 4A, except spinach, beans, dry and succulent, kiwi fruit, citrus crop group, citrus, dried pulp, citrus, oil, pomegranate, pome fruit group 11, yam, and melon subgroup 9A. Secondary residues in animal commodities were estimated based on theoretical worst-case, yet nutritionally adequate animal diets and transfer information from feeding studies.

ii. Drinking water. Fludioxonil rapidly degrades via photolysis on the soil surface and in water. The half-lives are 1 day and 10 days, respectively. This potential for rapid degradation reduces the potential for ground water or surface water exposure. Fludioxonil Kocs range from 991 to 2,440 indicating a relatively high affinity for binding to soil. Estimated Environmental Concentrations (EECs) of fludioxonil in drinking water were determined for the highest use rate of fludioxonil (turfgrass use). Screening Concentration in Ground Water (SCI-GROW) (Version 2.2) was used to determine acute and chronic EECs in ground water and Food Quality Protection Act (FQPA) Index Reservoir Screening Tool (FIRST) (Version 1.0) was used to determine acute and chronic EECs in surface water. Based on the model outputs, the ground water EECs for fludioxonil are 0.174 parts per billion (ppb) for acute and chronic exposure. The surface water EECs were 70 ppb and 26 ppb for acute and chronic exposure, respectively.

2. Non-dietary exposure. There is a potential residential post-application exposure to adults and children entering residential areas treated with fludioxonil. 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

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 fludioxonil 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 fludioxonil has a common mechanism of toxicity with other substances.

E. Safety Determination

1. U.S. population—i. Acute: For the purpose of the aggregate risk assessment, the exposure value was expressed in terms of margin of exposure (MOE), which was calculated by dividing the no observable adverse effect level (NOAEL) by the exposure for each population subgroup. In addition, exposure was expressed as a percent of the acute reference dose (%aRfD). Acute exposure to the females 13-50 years subpopulation resulted in a MOE of 1,919 (5.2% of the acute RfD of 1.0 milligrams/kilograms - bodyweight/day (mg/kg-bw/day)). Since the benchmark MOE for this assessment was 100 and since EPA generally has no concern for exposures below 100% of the RfD, Syngenta believes that there is a reasonable certainty that no harm will result from dietary (food) exposure to residues arising from the current and proposed uses for fludioxonil.

Acute drinking water levels of comparison (DWLOC) were calculated based on an acute populated adjusted dose (aPAD) of 1 mg/kg/day. The females (13-50 years) subpopulation generated an acute DWLOC of approximately 28,440 ppb. The acute EEC of 70 ppb is considerably less than 28,440 ppb. The chronic and aggregate risk from fludioxonil residues in food and drinking water would; therefore, not be expected to exceed the EPA's level of concern.

ii. Chronic: The chronic exposure to the most exposed sub-population (children 1 and 2 years old) resulted in a MOE of 753 (13.3% of the chronic RfD of 0.033 mg/kg-bw/day). The chronic dietary exposure analysis (food only) indicated that exposure from all established and proposed fludioxonil uses would be 13.3% of the chronic RfD of 0.033 mg/kg-bw/day for the most sensitive subpopulation, children 1 and 2 years old.

Estimated concentrations of fludioxonil residues in surface and ground water were below the calculated acute DWLOC. The children 1 and 2 years old subpopulation had the lowest chronic DWLOC of approximately 286 ppb, which is considerably higher than the chronic EEC of 26 ppb.

Based on the completeness and reliability of the toxicity data supporting these petitions, and the results of the above exposure calculations, Syngenta believes that there is a reasonable certainty that no harm will result from aggregate exposure to residues arising from all current and proposed fludioxonil uses, including anticipated dietary exposure from food, water, and all other types of non-occupational exposures.

2. Infants and children. No additional FQPA safety factor was applied. 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 fludioxonil.
