Interregional Research Project Number 4 (IR-4)
PP 3E6777, 3E6788, and 3E6779
EPA has received pesticide petitions (PP 3E6777, 3E6788, and 3E6779) from 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 180.568 by establishing tolerances for residues of flumioxazin, 2-[7-fluoro-3,4-dihydro-3-oxo-4-(2-propynyl)-2 H-1,4-benzoxazin-6-yl]-4,5,6,7-tetrahydro-1 H-isoindole-1,3(2 H)-dione, in or on the following raw agricultural commodities:
1. PP 3E6777 proposes tolerances for peppermint, tops; peppermint, oil; spearmint, tops; and spearmint, oil at 0.04 parts per million (ppm).
2. PP 3E6788 proposes tolerances for onion, dry bulb; garlic, bulb; and shallot, bulb at 0.02 ppm.
3. PP 3E6779 proposes tolerances for vegetable, tuberous and corm subgroup 1C at 0.02 ppm.
EPA has determined that the petitions contain data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the petitions. Additional data may be needed before EPA rules on the petitions. This notice includes a summary of the petitions prepared by Valent USA Corporation, P.O. Box 8025, Walnut Creek, CA 94596-8025.
A. Residue Chemistry
1. Plant metabolism. The metabolism of flumioxazin is adequately understood for the purpose of the proposed tolerances.
2. Analytical method. Practical analytical methods for detecting and measuring levels of flumioxazin have been developed and validated in/on all appropriate agricultural commodities and respective processing fractions. The limit of quantification (LOQ) of flumioxazin in the methods is 0.02 ppm which will allow monitoring of food Start Printed Page 12686with residues at the levels proposed for the tolerances.
3. Magnitude of residues. Residue data on potato, onion, and mint have been submitted which adequately supports the requested tolerances.
B. Toxicological Profile
The toxicological profile for flumioxazin which supports these petitions for tolerances was previously published in the Federal Register of April 18, 2001 (66 FR 19870) (FRL-6778-5).
C. Aggregate Exposure
1. Dietary exposure—i. Food. Acute and chronic dietary analyses were conducted to estimate exposure to potential flumioxazin residues in/on the following crops: Peanuts and soybeans (existing tolerances), cotton, grapes, almond, pistachio, and sugarcane (tolerances pending), vegetable, tuberous and corm (Subgroup 1C), onion, dry bulb and mint (tolerances proposed in the current petitions), and nut, tree (Group 14), fruit, pome (Group 11), and fruit, stone (Group 12) (tolerances to be proposed in the future). The Cumulative and Aggregate Risk Evaluation System (CARES) Version 1.1 was used to conduct this assessment. Proposed tolerances and conservative estimates for percentages of the crop treated were used in these assessments. No adjustments were made for common washing, cooking or preparation practices. Exposure estimates for water were made based upon modeling General Expected Environmental Concentration (GENEEC 1.2).
ii. Drinking water. Since flumioxazin is applied outdoors to growing agricultural crops, the potential exists for the parent or its metabolites to reach ground water or surface water that may be used for drinking water. Because of the physical properties of flumioxazin, it is unlikely that flumioxazin or its metabolites can leach to potable ground water. To quantify potential exposure from drinking water, surface water concentrations for flumioxazin were estimated using GENEEC 1.2. Because KOC could not be measured directly in adsorption-desorption studies because of chemical stability, GENEEC values representative of a range of KOC values were modeled. The simulation that was selected for these exposure estimates used an average KOC of 385, indicating high mobility. The peak GENEEC concentration predicted in the simulated pond water was 9.8 parts per billion (ppb). Using standard assumptions about body weight and water consumption, the acute exposure from this drinking water would be 0.00028 and 0.00098 milligrams/kilogram/day (mg/kg/day) for adults and children, respectively. The 56-day GENEEC concentration predicted in the simulated pond water was 0.34 ppb.
2. Non-dietary exposure. Flumioxazin is proposed only for agricultural uses and no homeowner or turf uses. Thus, no non-dietary risk assessment is needed.
D. Cumulative Effects
Section 408(b)(2)(D)(v) requires that the Agency must consider “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.” Available information in this context include not only toxicity, chemistry, and exposure data, but also scientific policies and methodologies for understanding common mechanisms of toxicity and conducting cumulative risk assessments. Although the Agency has some information in its files that may turn out to be helpful in eventually determining whether a pesticide shares a common mechanism of toxicity with any other substances, EPA does not at this time have the methodologies to resolve the complex scientific issues concerning common mechanism of toxicity in a meaningful way for most registered pesticides.
E. Safety Determination
1. U.S. population. The potential acute exposure from food to the U.S. population and various non-child/infant population subgroups will utilize at most 14.2% of the acute reference dose (aRfD). Addition of the worse case, dietary exposure from water (0.00028 mg/kg/day) increases this exposure at the 99.9th percentile to 23.7% of the aRfD. The Agency has no cause for concern if total acute residue contribution is less than 100% of the aRfD, because the aRfD represents the level at or below which daily aggregate exposure over a lifetime will not pose appreciable risk to human health. Therefore, it can be concluded that there is a reasonable certainty that no harm will result to the overall U.S. population from aggregate, acute exposure to flumioxazin residues.
2. Chronic risk. The potential chronic exposure from food to the U.S. population and various non-child/infant population subgroups will utilize at most 2.5% of the chronic reference dose (cRfD). The population subgroup with the highest exposure was the U.S. population, western states. Addition of the worse case, dietary exposure from water (0.0000097 mg/kg/day) increases this exposure at the 100th percentile to 3.0% of the cRfD. The Agency has no cause for concern if total chronic residue contribution is less than 100% of the cRfD, because the cRfD represents the level at or below which daily aggregate exposure over a lifetime will not pose appreciable risk to human health. Therefore, it can be concluded that there is a reasonable certainty that no harm will result to the overall U.S. population from aggregate, chronic exposure to flumioxazin residues.
3. Infants and children—i. Safety factor for infants and children. The FQPA safety factor has been retained at 10X in assessing the risk posed by flumioxazin. The reasons for retaining the 10X safety factor are as follows. First, there is evidence of increased susceptibility of rat fetuses to in utero exposure to flumioxazin by the oral and dermal route in the prenatal developmental toxicity studies in rats. In addition, there is evidence of increased susceptibility of young animals exposed to flumioxazin in the 2-generation reproduction toxicity study in rats. Finally, there is concern for the severity of the effects observed in fetuses and young animals when compared to those observed in the maternal and parental animals.
Since the additional 10X safety factor has been retained to account for the apparent increased susceptibility from prenatal or postnatal exposures to flumioxazin, it would be appropriate to apply the extra 10X safety factor to only selected subpopulations, e.g. infants and children <6 years old and females >13 years old. For these assessments, however, the 10X safety factor has been applied to all population subgroups for all exposure durations (acute and chronic), thus making these assessments additionally conservative.
ii. Acute risk. The potential acute exposure from food to children 1-2 years old (the most highly exposed child/infant subgroup) will utilize at most 26.3% of the aRfD. Addition of the worse case, dietary exposure from water (0.00098 mg/kg/day) increases this exposure at the 99.9th percentile to 59% of the aRfD. Therefore, it can be concluded that there is a reasonable certainty that no harm will result to infants and children from aggregate, acute exposure to flumioxazin residues.
iii. Chronic risk. The potential chronic exposure from food to children 1-2 years old (the most highly exposed child/infant subgroup) will utilize at most 2.4% of the cRfD. Addition of the worse case, dietary exposure from water (0.000034 mg/kg/day) increases this exposure at the 100th percentile to 4.2% of the cRfD. Therefore, it can be concluded that there is a reasonable Start Printed Page 12687certainty that no harm will result to infants and children from aggregate, chronic exposure to flumioxazin residues.
F. International Tolerances
Flumioxazin has not been evaluated by the Joint Meeting on Pesticide Residues and there are no Codex Maximum Residue Limits (MRL) for flumioxazin. MRL values have been established to allow the following uses of flumioxazin in the following countries:
1. Argentina, soybean at 0.015 ppm and sunflower at 0.02 ppm.
2. Brazil, soybean at 0.05 ppm.
3. France, grape at 0.05 ppm.
4. Paraguay, soybean at 0.015 ppm.
5. South Africa, soybean at 0.02 ppm and groundnut at 0.02 ppm.
6. Spain, soybean at 0.05 ppm and peanut at 0.05 ppm.End Supplemental Information
