SUMMARY:

This regulation establishes tolerances for residues of famoxadone (3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione) in or on vegetables, fruiting, group 8 (except tomato) at 4.0 parts per million (ppm), tomato at 1.0 ppm; vegetables cucurbit, group 9 at 0.30 ppm; lettuce, head at 10.0 ppm; potato at 0.02 ppm; grape at 2.50 ppm; grape, raisin at 4.0 ppm; fat of cattle, horses, goats, sheep at 0.02 ppm; liver of cattle, horses, goats, sheep at 0.05 ppm; and milk fat (reflecting negligible residues in whole milk) at 0.060 ppm. E.I. Dupont Nemours and Company (Dupont) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA). These reflect the first food tolerances for this fungicide in the United States.

II. Background and Statutory Findings-

In the Federal Register of January 10, 2001 (66 FR 1981) (FRL-6760-8), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of a pesticide petition (PP 0F6070) for establishing tolerances for potatoes at 0.05 ppm, curcurbit vegetable crop group (cucumbers, melon, squash) at 0.7 ppm; fruiting vegetable crop group (tomatoes, and peppers) at 1.0 ppm; and head lettuce at 15 ppm by Dupont, P.O. Box 80038, Wilmington, DE 19880-0038. That notice included a summary of the petition prepared by Dupont, the registrant. There were no comments received in response to the notice of filing.

In a second Federal Register of August 1, 2001 (66 FR 39762) (FRL-6789-2), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of a pesticide petition (PP 7E4847) for establishing a tolerance for grapes at 2.0 parts per million by Dupont, P.O. Box 80038, Wilmington, DE 19880-0038. That notice included a summary of the petition prepared by Dupont, the registrant. The Agency received a written comment from the World Wildlife Fund (WWF) dated August 31, 2001. The Agency's response to this comment can be found at Unit III.B.-

The initial petitions requested that 40 CFR 180.587 be amended by establishing tolerances for residues of the fungicide famoxadone (3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione) in or on potatoes at 0.05 ppm; cucurbit vegetable crop group at 0.7 ppm; fruiting vegetable crop group at 1.0 ppm; head lettuce at 15 ppm; grapes at 2.0 ppm; and raisins at 4.0 ppm.-

Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) of the FFDCA defines “safe” to mean that “there is a reasonable certainty that no harm will Start Printed Page 39463result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of the FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue....”-

EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of the FFDCA and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

III. Aggregate Risk Assessment and Determination of Safety-

Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure, consistent with section 408(b)(2) of the FFDCA, for tolerances for residues of famoxadone on vegetables, fruiting, group 8 (except tomato) at 4.0 ppm; tomato at 1.0 ppm; vegetables, cucurbit, group 9 at 0.30 ppm; lettuce, head at 10.0 ppm; potato at 0.02 ppm; grape at 2.50 ppm; grape, raisin at 4.0 ppm; fat of cattle, horses, goats, sheep at 0.02 ppm; liver of cattle, horses, goats, sheep at 0.05 ppm and milk, fat (reflecting negligible residues in whole milk) at 0.060 ppm. EPA's assessment of exposures and risks associated with establishing the tolerance follows.

A. Toxicological Profile-

EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. The nature of the toxic effects caused by famoxadone are discussed in Table 1 of this unit as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies reviewed.

Unchanged parent (51-84% of administered dose) and 2 hydroxylated metabolites (IN-KZ534 and IN-KZ007) were the major components recovered in the feces. No significant qualitative or quantitative differences were observed for sex, dose level, or repeated dosing.
870.7485Metabolism and pharmacokinetics, dogs (males only)Absorption was limited. Most of the administered dose (62%) was eliminated in the feces within 24 hours; very little (about 8%)was eliminated in the urine. Initially, unchanged parent (94-97% of radioactivity in feces) was recovered in the feces, but later (>24 hrs) unchanged parent (12-35% of radioactivity in feces), IN-KZ007 (21-3% of radioactivity in feces) and IN-ML815 (4-9% of radioactivity in feces) were recovered. Even later (>48 hrs), trace amounts of the hydroxylated metabolites IN-KZ532 and IN-KZ534 were also identified in the feces.

B. Toxicological Endpoints-

The dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intraspecies differences.-

For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by the appropriate UF (RfD = NOAEL/UF). Where an additional safety factors (SF) is retained due to concerns unique to the FQPA, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of FQPA SF.-

For non-dietary risk assessments (other than cancer) the UF is used to determine the LOC. For example, when 100 is the appropriate UF (10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC.-

The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk. A Q* is calculated and used to estimate risk which represents a probability of occurrence of additional cancer cases (e.g., risk is expressed as 1 x 10-6 or one in a million). Under certain specific circumstances, MOE calculations will be used for the carcinogenic risk assessment. In this non-linear approach, a “point of departure” is identified below which carcinogenic effects are not expected. The point of departure is typically a NOAEL based on an endpoint related to cancer effects though it may be a different value derived from the dose response curve. To estimate risk, a ratio of the point of departure to exposure (MOEcancer = point of departure/exposures) is calculated. A summary of the toxicological endpoints for famoxadone used for human risk assessment is shown in Table 2 of this unit:Start Printed Page 39466

a The UF of 1,000 includes the conventional 100 and an additional 10 for the use of the LOAEL and dose from a subchronic (13-week) study for chronic risk assessment.
b Regarding the chronic RfD for famoxadone, a 1-year chronic feeding study in dogs is available, but was determined to not be an appropriate study for use in chronic risk assessment at this time. Although the testing laboratory reported a NOAEL of 1.2 mg/kg/day for treatment-related lens lesions (cataracts) in the eyes of the male and female dogs, a subsequent evaluation by a consulting pathologist of the microscopic sections of the eyes from all dogs in this study strongly suggested that a serious fixation artifact affected all the eye sections such that only prominent cataracts were detectable and as a consequence, a NOAEL could not be reliably determined with any degree of confidence. Considering this second evaluation, the Agency concluded that this fixation artifact may have had a profound effect on the interpretation of the histopathological findings in the eyes of all dogs in this study. In view of the considerable uncertainty relating to the microscopic findings in the eyes of all dogs in this study and the resulting uncertainty with regard to determining a NOAEL for eye effects, the Agency decided to not use the results from this 1-year study for the purpose of determining a chronic RfD for famoxadone at this time. Based on a consideration of findings in the eyes of dogs in both the 13-week and 1-year feeding studies, it was determined that the lowest dose at which evidence of cataracts was actually observed was in the female dogs in the 13-week study at the lowest dose tested of 1.4 mg/kg/day (the LOAEL). This 13-week study, rather than the 1-year study, was selected to be the most appropriate study for chronic risk assessment at this time. Since a LOAEL, rather than a NOAEL, and a subchronic study, rather than a chronic study, were used to determine the chronic RfD, an additional 10x UF was added to the conventional UF of 100x. The chronic RfD (LOAEL of 1.4 mg/kg/day/UF of 1,000) for famoxadone was determined to be 0.0014 mg/kg/day.

The comment received from WWF concerned a toxicity issue in particular: The potential for famoxadone to be an endocrine disruptor. WWF quoted the notice of filing which was written by Dupont. “Chronic, lifespan and multi-generational bioassays in mammals and acute and subchronic studies on aquatic organisms and wildlife did not reveal endocrine effects. Any endocrine related effects would have to have been detected in this definitive array of required tests. The probability of any such effects due to agricultural uses of famoxadone is negligible.” WWF stated that pursuant to FQPA, the Agency is establishing a new endocrine disruptor screening and testing program because existing toxicology protocols are not adequate to detect endocrine disruption. Therefore, Dupont's evaluation of the endocrine disruptor potential is incomplete and consequently misleading. WWF also urges the Agency to consider not only evidence of increasedsusceptibility, but also the significance of endocrine disruptor data gaps when determining the FQPA SF for famoxadone.

In response to the WWF the Agency notes that FQPA requires EPA to develop a screening program to determine whether certain substances (including all pesticide active and other ingredients) may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or such other endocrine effect... EPA has been working with interested stakeholders to develop a screening and testing program as well as a priority-setting scheme. In the available toxicity studies on famoxadone, no evidence of endocrine-related effects was observed. However, famoxadone may be subjected to further screening and/or testing to better characterize potential effects related to endocrine disruption when additional appropriate screening and/or testing protocols have been developed by the Agency's Endocrine Disruptor and Testing Advisory Committee (EDSTAC).

C. Exposure Assessment

-1. Dietary exposure from food and feed uses. Tolerances are being established for (40 CFR 180.587) for the residues of famoxadone, in or on a variety of raw agricultural commodities. Risk assessments were conducted by EPA to assess dietary exposures from famoxadone in food as follows:

-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 one day or single exposure. No toxicological endpoint attributable to a single-oral dose was identified in the available toxicology studies on famoxadone that would be applicable to females (13-50 years) or to the general population (including infants and children). Therefore, famoxadone is not expected to pose an acute dietary risk.

ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model (DEEMTM) analysis evaluated the individual food consumption as reported by respondents in the USDA 1994-1996 and 1998-nationwide Continuing Surveys of Food Intake by Individuals (CSFII) and accumulated exposure to the chemical for each commodity. The following assumptions were made for the chronic exposure assessments: Anticipated residues based upon average field trial values and assumptions that 100% of each crop is treated with famoxadone.

-iii. Cancer. The Agency has classified famoxadone as not likely to be Start Printed Page 39467carcinogenic to humans. As such, famoxadone is not expected to pose a cancer dietary risk.

-iv. Anticipated residue and percent crop treated (PCT) information.

-Section 408(b)(2)(E) of the FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide chemicals that have been measured in food. If EPA relies on such information, EPA must require that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating that the levels in food are not above the levels anticipated. Following the initial data submission, EPA is authorized to require similar data on a time frame it deems appropriate. No PCT information was used in the risk assessment. The Agency used 100% which would over estimate exposure.--

2. Dietary exposure from drinking water. -

The Agency lacks monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for famoxadone in drinking water because this is a new chemical. Because the Agency does not have comprehensive monitoring data, drinking water concentration estimates are made by reliance on simulation or modeling taking into account data on the physical characteristics of famoxadone.-

The Agency uses the FQPA Index Reservoir Screening Tool (FIRST) or the Pesticide Root Zone/Exposure Analysis Modeling System (PRZM/EXAMS) to estimate pesticide concentrations in surface water and SCI-GROW, which predicts pesticide concentrations in groundwater. In general, EPA will use FIRST (a tier 1 model) before using PRZM/EXAMS (a tier 2 model) for a screening-level assessment for surface water. The FIRST model is a subset or meta-model of the PRZM/EXAMS model that uses specific high-end runoff scenario for pesticides. FIRST incorporates an index reservoir environment and a percent crop area (PCA), while PRZM/EXAMS incorporate an index reservoir environment, PCA, all available information on the pesticide's fate and use pattern, and site-specific cropping information.-

None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would exceed human health levels of concern.-

Since the models used are considered to be screening tools in the risk assessment process, the Agency does not use estimated environmental concentrations (EECs) from these models to quantify drinking water exposure and risk as a %RfD or %PAD. Instead drinking water levels of comparison (DWLOCs) are calculated and used as a point of comparison against the model estimates of a pesticide's concentration in water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food, and from residential uses. Since DWLOCs address total aggregate exposure to famoxadone they are further discussed in the aggregate risk sections in Unit E. -

Based on the PRZM/EXAMS and SCI-GROW models the EECs of famoxadone for chronic exposures are estimated to be 0.47 parts per billion (ppb) for surface water and 0.23 ppb for ground water. -

3. From non-dietary exposure. The term “residential exposure” is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets).

Famoxadone is not registered for use on any sites that would result in residential exposure.-

4. Cumulative exposure to substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of the FFDCA 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 famoxadone 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, famoxadone 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 famoxadone has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the final rule for Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997).

D. Safety Factor for Infants and Children-

1. In general. Section 408 of the FFDCA provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans.-

2. Prenatal and postnatal sensitivity. The Agency concluded that there is not a concern for pre- and/or postnatal toxicity resulting from exposure to famoxadone.-

No quantitative or qualitative evidence of increased susceptibility, as compared to adults, of rat or rabbit fetuses to in utero exposure to famoxadone was observed in the developmental toxicity studies. No quantitative or qualitative evidence of increased susceptibility, as compared to adults, of rat fetuses or neonates was observed in the 2-generation reproduction study. -

In the rat developmental toxicity study, the NOAEL for maternal toxicity was 250 mg/kg/day and the LOAEL was 500 mg/kg/day, based on transient decreases in body weight gain and food consumption. At 1,000 mg/kg/day, no additional treatment-related effects were observed in the dams. No developmental toxicity was observed in the rat study. The NOAEL for developmental toxicity was 1,000 mg/kg/day, the highest dose tested.-

In the rabbit developmental toxicity study, the maternal and developmental NOAELs and LOAELs were the same. The NOAEL for maternal toxicity and developmental toxicity was 350 mg/kg/day. The LOAEL for maternal toxicity was 1,000 mg/kg/day, based on abortions in 4 out of 17 does; markedly decreased body weight, reduced body weight gain and reduced food consumption in the same 4 does, and increased number of does with abnormal or little or no stools. The LOAEL for developmental toxicity was 1,000 mg/kg/day; based on abortions in 4 out of 17 does; and equivocal increases in percent post implantation loss and mean number of resorptions Start Printed Page 39468per doe. In the rabbit study, maternal toxicity (does) and developmental toxicity (fetuses) are considered to be equally sensitive to the test material. Therefore, based on the results in these two developmental toxicity studies in rats and rabbits, no increased susceptibility of the fetuses (as compared to adults) was demonstrated for famoxadone.-

In the 2-generation reproduction study in rats, the NOAEL for parental toxicity was 200 ppm (equal to 11.3/14.2 mg/kg/day, M/F) and the LOAEL was 800 ppm (44.7/53.3 mg/kg/day, M/F), based on decreased body weight, body weight gain, and food consumption; and heptotoxicity in the liver. Also, at 800 ppm, adaptive hepatocellular responses indicating enzyme induction were observed. No reproductive toxicity was observed in this study. The NOAEL for reproductive toxicity was 800 ppm (44.7/53.3 mg/kg/day, M/F), the highest dose tested. In this same study, the NOAEL for offspring toxicity was 200 ppm (equal to 11.3/14.2 mg/kg/day, M/F) and the LOAEL was 800 ppm (44.7/53.3 mg/kg/day, based on decreased body weights for F1 and F2 pups throughout their respective lactation periods.

3. Neurotoxicity. The Agency concluded that there is not a concern for developmental neurotoxicity resulting from exposure to famoxadone and that a developmental neurotoxicity study is not required.-

Although clinical signs of neurotoxicity were observed in dogs in the 13-week study at the highest dose tested (>20 mg/kg/day), this effect was not observed at lower doses of about 10 mg/kg/day in the same 13-week study or in a subsequently performed 1-year feeding study in dogs. Also, toxicologically significant signs of neurotoxicity were not observed in any of the other studies on famoxadone in any species (including rats, mice, or monkeys) at any time. In addition, pre- and postnatal studies in rats and rabbits demonstrated no increased susceptibility of fetuses or neonates to famoxadone as compared to adults. Toxicologically significant neurotoxic effects would not be expected to occur in an additional study in rats. The clinical signs of neurotoxicity (muscle twitches) observed only in dogs, only in males, and only at the highest dose tested, would not be anticipated to occur in a developmental neurotoxicity study in rats.--

4. Conclusion. The Agency concluded that the toxicology database was complete for FQPA purposes and that there are no residential uncertainties for pre-/postnatal toxicity. Based on the hazard data, the Agency recommended the special FQPA SF be reduced to 1x. The famoxadone risk assessment team evaluated the quality of the exposure data; and, based on these data, recommended that the special FQPA SF be reduced to 1x. The recommendation is based on the following:-

i. There is no quantitative or qualitative evidence of increased susceptibility of rat and rabbit fetuses to in utero exposure in developmental studies. There is no quantitative or qualitative evidence of increased susceptibility of rat offspring in the multi-generation reproduction study. -

ii. The chronic dietary food exposure assessment utilizes average field trial residue data and for all proposed uses, 100% crop treated is assumed. The chronic assessment is somewhat refined and based on reliable data derived from studies designed to produce worst-case residues and unlikely to underestimate exposure.

E. Aggregate Risks and Determination of Safety-

To estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses, the Agency calculates DWLOCs which are used as a point of comparison against the model estimates of a pesticide's concentration in water. DWLOC values are not regulatory standards for drinking water. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses. In calculating a DWLOC, the Agency determines how much of the acceptable exposure (i.e., the PAD) is available for exposure through drinking water e.g., allowable chronic water exposure (mg/kg/day) = cPAD - (average food + residential exposure). This allowable exposure through drinking water is used to calculate a DWLOC.-

A DWLOC will vary depending on the toxic endpoint, drinking water consumption, and body weights. Default body weights and consumption values as used by the USEPA Office of Water are used to calculate DWLOCs: 2 liter (L)/70 kg (adult male), 2L/60 kg (adult female), and 1L/10 kg (child). Default body weights and drinking water consumption values vary on an individual basis. This variation will be taken into account in more refined screening-level and quantitative drinking water exposure assessments. Different populations will have different DWLOCs. Generally, a DWLOC is calculated for each type of risk assessment used: Acute, short-term, intermediate-term, chronic, and cancer.-

When EECs for surface water and groundwater are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to the pesticide in drinking water (when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because OPP considers the aggregate risk resulting from multiple exposure pathways associated with a pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, OPP will reassess the potential impacts of residues of the pesticide in drinking water as a part of the aggregate risk assessment process.-

1. Acute risk. No appropriate endpoint attributable to a single-oral dose was identified in the available toxicology studies on famoxadone. Therefore, no acute risk from famoxadone is not expected.--

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to famoxadone from food will utilize 36% of the cPAD for the U.S. population, 76% of the cPAD for Children ages 1-2 and 68% of the cPAD for Children ages 3-5. Children ages 1-2 are expected to be the most highly exposed subpopulation to famoxadone. There are no residential uses for famoxadone. In addition, there is potential for chronic dietary exposure to famoxadone in drinking water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect the aggregate exposure to exceed 100% of the cPAD, as shown in Table 3 of this unit:

Table 3.—Aggregate Risk Assessment for Chronic (Non-Cancer)Exposure to Famoxadone

Population SubgroupcPAD mg/kg/day% cPAD (Food)Surface Water EEC (ppb)Ground Water EEC (ppb)Chronic DWLOC (ppb)
U.S. Population0.001436%0.470.2331
Start Printed Page 39469
Children 1-2 years old0.001476%0.470.233.4
Children 3-5 years old0.001468%0.470.234.5

3. Short-term risk. Short-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background-exposure level). Famoxadone 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.

4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background-exposure level). Famoxadone 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.

5. Aggregate cancer risk for U.S. population. Famoxadone is classified as “not likely to be carcinogenic to humans.” As such, no cancer risk is expected.

6. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, including infants and children, from aggregate exposure to famoxadone residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Famoxadone was screened through multi-residue methods listed in the Pesticide Analytical Manual Volume I (PAM Vol. I), Third Edition (January 1994), using Protocols C to E. Protocols A and B were not used because famoxadone does not have an n-methyl carbamate structure (Protocol A), nor is it an acid or phenol (Protocol B). Protocol C showed good analytical response using the electron-capture detector (ECD) and nitrogen-phosphorus detector (NPD). Good recoveries were obtained for the analysis of wine, grapes, and tomatoes (92-138%) using Protocol D. Food commodities can be analyzed for famoxadone residues using the appropriate extraction method with the mixed ether elution system, resulting in recovery values of 92 to 108%.

The multi-residue methods testing appears to be scientifically acceptable and has been sent to the FDA for further evaluation. Preliminary analysis suggests that Protocol D may be appropriate for analysis of famoxadone in plant matrices and has the potential to be the primary enforcement method.

Adequate enforcement methodology is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

No CODEX maximum residue limits currently exist for famoxadone: Maximum Residue Levels (MRLs) have been established for potatoes in the Netherlands at 0.02 ppm and for grapes in Germany at 2.0 ppm.

V. Conclusion-

Therefore, tolerances are established for residues of famoxadone (3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione) in or on vegetables, fruiting, group 8 (except tomato) at 4.0 ppm; tomato at 1 ppm; vegetables cucurbit, group 9 at 0.30 ppm; lettuce, head at 10.0 ppm; potato at 0.02 ppm grape at 2.50 ppm (import only); raisin at 4.0 ppm (import only); fat of cattle, horses, goats, sheep at 0.02 ppm; liver of cattle, horses, goats, sheep at 0.05 ppm; and milk, fat (reflecting negligible residues in whole milk) at 0.060 ppm.

VI. Objections and Hearing Requests-

Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of the FFDCA provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d) of FFDCA, as was provided in the old sections 408 and 409 of the FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

You may also submit an electronic copy of your request at many Federal Depository Libraries.

B. When Will the Agency Grant a Request for a Hearing?-

A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32).--

VII. Statutory and Executive Order Reviews--

This final rule establishes a tolerance under section 408(d) of the FFDCA in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because this rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). Nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since tolerances and exemptions that are established on the basis of a petition under section 408(d) of the FFDCA, such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of the FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.-Start Printed Page 39471

VIII. Congressional Review Act -

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of this final rule in the Federal Register. This final rule is not a “major rule” as defined by 5 U.S.C. 804(2).
