II. Background and Statutory Findings

In the Federal Register of May 30, 2001 (66 FR 29213)(FRL-6782-9), EPA issued a notice pursuant to section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a, as amended by the Food Quality Protection Act of 1996 (FQPA) (Public Law 104-170), announcing the filing of a pesticide petition (PP 0F06082) by Aventis CropScience (formerly Rhone-Poulenc Ag Company), P.O. Box 12014, #2 T.W. Alexander Drive, Research Triangle Park, NC 207709. This notice included a summary of the petition prepared by Aventis CropScience, the registrant. There were no comments received in response to the notice of filing.

The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the insecticide acetamiprid N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methylacetamidine, in or on brassica (cole crops) at 1.2 parts per million (ppm), canola seed and mustard seed at 0.01 ppm, citrus at 0.5 ppm, cottonseed at 0.06 ppm, fruiting vegetables at 0.2 ppm, grapes at 0.2 ppm, leafy vegetables at 3.0 ppm, and pome fruits at 0.70 ppm. The Agency will not address the canola seed and mustard seed tolerances at this time.

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) defines “safe” to mean that“ there is a reasonable certainty that no harm will result 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) 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 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), 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), for tolerances for residues of the insecticide acetamiprid N1-[(6-chloro-3-pyridyl)methyl]- N2-cyano-N1-methylacetamidine in or on citrus fruit group at 0.50 ppm, citrus dried pulp and leafy brassica vegetable group at 1.20 ppm each, cotton gin byproducts at 20.0 ppm, cotton undelinted seed at 0.60 ppm, leafy vegetable group (except brassica) at 3.0 ppm, fruiting vegetable group and grape at 0.20 ppm each, pome fruit group at 1.0 ppm, and tomato paste at 0.40 ppm; and tolerances for the combined residues of acetamiprid and IM-2-1 N1-[(6-chloro-3-pyridyl) methyl]-N2-cyano-acetamidine in or on meat and fat of cattle, hog, horse, goat, and sheep at 0.10 ppm each; meat byproducts of cattle, hog, horse, goat, and sheep at 0.20 ppm each; milk at 0.10 ppm; poultry eggs, meat and fat at 0.010 ppm each; and poultry liver at 0.050 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 acetamiprid are discussed in the following Table 1 as well as the no observed adverse effect level (NOAEL) and the lowest observed adverse effect level (LOAEL) from the toxicity studies reviewed.

870.7485Metabolism - mouse, rat, rabbit Special StudyMale mice, rats or rabbits were administered single doses of acetamiprid by gavage, intraperitoneal injection (i.p.) or intravenous injection (i.v.) up to 60 mg/kg. The animals were assessed for a variety of neurobehavioral parameters. In vitro experiments were also done using isolated ileum sections from guinea pigs to assess contractile responses in the absence and presence of agonists (acetylcholine, histamine diphosphate, barium chloride and nicotine tartrate). Acetamiprid was also assessed via i.v. in rabbits for effects on respiratory rate, heart rate and blood pressure; via gavage in mice for effects on gastrointestinal motility; and via i.p. in rats for effects on water and electrolyte balance in urine, and blood coagulation, hemolytic potential and plasma cholinesterase activity. Based on a number of neuromuscular, behavioral and physiological effects of acetamiprid in male mice, under the conditions of this study, a overall NOAEL of 10 mg/kg (threshold) and LOAEL of 20 mg/kg could be estimated for a single dose by various exposure routes.
870.7485Metabolism and pharmacokinetics - ratExtensively and rapidly metabolized. Metabolites 79-86% of administered dose. Profiles similar for males and females for both oral and intravenous dosing. Thirty-seven percent of dose recovered in urine and feces as unchanged test article. Urinary and fecal metabolites from 15-day repeat dose experiment only showed minor differences from single-dose test. Initial Phase I biotransformation: demethylation of parent. 6-chloronicotinic acid most prevalent metabolite. Phase II metabolism shown by increase in glycine conjugate.
870.7600Dermal absorptionThe majority of the dose was washed off with the percent increasing with dose. Skin residue was the next largest portion of the dose with the percent decreasing with dose. In neither case was there evidence of an exposure related pattern. Absorption was small and increased with duration of expure. Since there are no data to demonstrate that the residues remaining on the skin do not enter the animal, then as a conservative estimate of dermal absorption, residues remaining on the skin will be added to the highest dermal absorption value. The potential total absorption at 24 hours could be approximately 30%.

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 intra species 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 factor 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 Safety Factor.

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 acetamiprid used for human risk Start Printed Page 14653assessment is shown in the following Table 2:

C. Exposure Assessment

1. Dietary exposure from food and feed uses. No tolerances have been established for the residues of acetamiprid, in or on raw agricultural commodities and no tolerances have been established for the combined residues of acetamiprid and IM-2-1 N1-[(6-chloro-3-pyridyl) methyl]-N2-cyano-acetamidine in or on meat, milk, poultry and egg commodities. Risk assessments were conducted by EPA to assess dietary exposures from acetamiprid 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. The Dietary Exposure Evaluation Model (DEEM®) analysis evaluated the individual food consumption as reported by respondents in the USDA 1989-1992 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 acute exposure assessments: The assessment assumed that 100% of the crops listed on the proposed label were treated and that crops listed on the label and livestock had residues of concern at the tolerance level. For processed commodities without a proposed tolerance, the analysis used the default processing factors provided with the model. A Tier 1 analysis results in highly conservative estimates of exposure and risk. Consideration of processing factors, anticipated residues in foods at the time of consumption, and percent of crop treated would result in Start Printed Page 14654lower exposure and risk estimates than those presented here. Even without such refinement, the acute dietary risk estimates are below the Agency's level of concern [i.e., <100% of the population-adjusted dose (PAD)] for all population subgroups. Dietary (food only) exposure estimates were greatest for the population subgroup composed of children ages 1-6 years old. Acute exposure is estimated to be 0.039606 mg/kg (95th percentile of exposure), which is equal to 40% of the acute population-adjusted dose (aPAD). The results are summarized in the accute dietary exposure portion of Table 3.

ii. Chronic exposure. In conducting this chronic dietary risk assessment the Dietary Exposure Evaluation Model (DEEM®) analysis evaluated the individual food consumption as reported by respondents in the USDA 1989-1992 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: The assessment assumed that 100% of the crops listed on the proposed label were treated and that crops listed on the label and livestock had residues of concern at the tolerance level. For processed commodities without a proposed tolerance, the analysis used the default processing factors provided with the model. A Tier 1 analysis results in highly conservative estimates of exposure and risk. Consideration of processing factors, anticipated residues in foods at the time of consumption, and percent of crop treated would result in lower exposure and risk estimates than those presented here. Even without such refinement the chronic dietary risk estimates are below the Agency's level of concern [i.e., <100% of the population-adjusted dose (PAD)] for all population subgroups. Chronic exposure is estimated to be 0.014687 mg/kg/day, which is equal to 64% of the cPAD. Although there is the potential for incidental ingestion of pesticide residues and soil from treated vegetables and foliage in home gardens via hand-to-mouth transfer, incidental oral exposure was not quantitatively assessed. Toddlers are not expected to spend a significant amount of time in a home garden and any resulting incidental oral exposures would be minimal and not quantifiable. Therefore, the Agency does not believe that incidental oral exposure from the requested homeowner uses will result in significant incidental oral exposures to children. The results are summarized in the chronic exposure portion of Table 3.

1 %aPAD and %cPAD are exposures presented as percentages of the acute and chronic population-adjusted doses, respectively. For acetamiprid, the aPAD = 0.1 mg/kg; the cPAD = 0.023 mg/kg/day.

iii. Cancer. The Agency classified acetamiprid into the category not likely to be carcinogenic to humans based on the absence of a dose-response and a lack of a statistically significant increase in the mammary adenocarcinoma incidence by pair-wise comparison of the mid- and high-dose groups with the controls. Although the incidence exceeded the historical control data from the same lab, it was within the range of values from the supplier.

2. Dietary exposure from drinking water. The Agency lacks sufficient monitoring exposure data to complete a comprehensive dietary exposure analysis and risk assessment for acetamiprid in drinking water. 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 acetamiprid.

The Agency uses the First Index Reservoir Screening Tool (FIRST) or the Pesticide Root Zone/Exposure Analysis Modeling System (PRZM/EXAMS), to produce estimates of pesticide concentrations in an index reservoir. The screening concentration in groundwater (SCI-GROW) model is used to predict pesticide concentrations in shallow groundwater. For a screening-level assessment for surface water EPA will use FIRST (a tier 1 model) before using PRZM/EXAMS (a tier 2 model). The FIRST model is a subset of the PRZM/EXAMS model that uses a specific high-end runoff scenario for pesticides. While both FIRST and PRZM/EXAMS incorporate an index reservoir environment, the PRZM/EXAMS model includes a percent crop area factor as an adjustment to account for the maximum percent crop coverage within a watershed or drainage basin.

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 coarse screen for sorting out pesticides for which it is highly unlikely that drinking water concentrations would Start Printed Page 14655ever 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 acetamiprid they are further discussed in the aggregate risk sections below.

Based on the FIRST and SCI-GROW models the EECs of acetamiprid for acute exposures are estimated to be 17 parts per billion (ppb) for surface water and 0.0008 ppb for ground water. The EECs for chronic exposures are estimated to be 4.0 ppb for surface water and 0.0008 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). Acetamiprid is proposed with this notice to be registered for use on the following residential non-dietary sites: ornamentals, flowers, vegetable gardens, and fruit trees. The risk assessment showed the following: for residential applicators, total MOEs for short- and intermediate-term residential dermal and inhalation exposures range from 1.2 × 105 to 6 × 105. For post-application activities, short- and intermediate-term MOEs range from 1.8 × 104 to 1.8 105 for adults and from 2.3 × 104 to 2.2 × 105 for youth ages 10-12 years. The residential uses for acetamiprid are not expected to result in long-term exposures.

4. 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 acetamiprid 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, acetamiprid 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 acetamiprid 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. FFDCA section 408 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 margin of exposure (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. There is no quantitative or qualitative evidence of increased susceptibility of rat or rabbit fetuses to in utero exposure in the developmental studies. In the rat, an increase in the incidence of shortening of the 13th rib was observed in fetuses at the same LOAEL as the dams, which exhibited reduced mean body weight, body weight gain and food consumption and increased liver weights. No developmental toxicity was observed in the rabbit at dose levels that induced effects in the does: body weight loss and decreased food consumption. In the multi-generation reproduction study, qualitative evidence of increased susceptibility of rat pups is observed. The parental and offspring systemic NOAELs are 17.9/21.7 (M/F) mg/kg/day and the offspring/parental systemic LOAELs are 51.0/60.1 mg/kg/day based on a decrease in mean body weight, body weight gain and food consumption in the parents and significant reductions in pup weights in both generations, reductions in litter size, and viability and weaning indices among F2 offspring as well as significant delays in the age to attain vaginal opening and preputial separation in the offspring. The offspring effects are considered to be more severe than the parental effects.

3. Conclusion. There is a complete toxicity data base for acetamiprid and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. The Agency FQPA Safety Factor Committee recommended that the FQPA safety factor be reduced to 3x in assessing the risk posed by this chemical. The Committee determined that the safety factor is necessary when assessing the risk posed by acetamiprid because there is qualitative evidence of increased susceptibility following prenatal/postnatal exposure to acetamiprid in the 2-generation reproduction study in rats. However, the Committee concluded that the safety factor could be reduced to 3x for acetamidprid because the toxicology database is complete; there is no quantitative or qualitative evidence of increased susceptibility following in utero exposure of rat and rabbit fetuses; the dietary (food and water) and residential exposure assessments will not underestimate the potential exposures for infants, children, and/or women of childbearing age; and the requirement of a developmental neurotoxicity study is not based on criteria reflecting special concern for the developing fetuses or young which are generally used for requiring a DNT study and a safety factor. The Committee recommended that the safety factor be required for all population subgroups when assessing chronic dietary exposures as well as when assessing residential short-, intermediate-, and long-term exposure durations to address the concern for the effects seen following prenatal/postnatal exposure to acetamiprid in the 2-generation reproduction study in rats; the FQPA Safety Factor can be removed (i.e., reduced to 1x) when assessing acute dietary 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 drinking water level of concerns (DWLOCs) which are used as a point of comparison against the model estimates of a pesticide's concentration in water (EECs). 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 from food and residential uses. In calculating a DWLOC, the Agency determines how much of the acceptable exposure (i.e., the population adjusted dose (PAD)) is available for Start Printed Page 14656exposure 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: 2L/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 aggregate risk assessment scenario: acute, short-term, intermediate-term, chronic, and cancer.

When EECs for surface water and groundwater are less than the calculated DWLOCs, the Office of Pesticide Programs (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. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food to acetamiprid will occupy 17% of the aPAD for the U.S. population, 11% of the aPAD for females 13 years and older, 38% of the aPAD for all infants (<1 year old) and 40% of the aPAD for children ages 1-6 years. In addition, there is potential for acute dietary exposure to acetamiprid 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 aPAD, as shown in the following Table 4:

Table 4.—Aggregate Risk Assessment for Acute Exposure to Acetamiprid

a Drinking Water Level of Comparison = aPAD-Acute Dietary Exposure (mg/kg/day) × body weight (kg) × 1,000 μg/mg ÷ water consumption (L/day). Body weight = 70 kg (males and general pop.), 60 kg (females), or 10 kg (infants and children). Consumption = 2 L/day for adults or 1 L/day for infants and children. Values have been rounded to 2 significant figures.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to acetamiprid from food will utilize 24% of the cPAD for the U.S. population, 45% of the cPAD for all infants (< 1 year old) and 64% of the cPAD for children ages 1-6 years. Based on the use pattern, chronic residential exposure to residues of acetamiprid is not expected. In addition, there is potential for chronic dietary exposure to acetamiprid 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 the following Table 5:

Values have been rounded to 2 significant figures.

3. Short-term risk and intermediate-term risk. Short-term and intermediate-term aggregate exposure takes into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Acetamiprid is currently proposed for uses that could result in short-term and intermediate residential exposure and the Agency has determined that it is appropriate to aggregate chronic food and water and short-term and intermediate exposures for acetamiprid. Using the exposure assumptions described in this unit for short- and intermediate-term exposures, EPA has concluded that aggregated food and residential exposures aggregated result in aggregate MOEs of 18,000 for adults, and 23,000 for youth (ages 10-12 years) for the non-oral routes of exposure (i.e., combined dermal and/or inhalation pathways). These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses. In addition, short-term DWLOCs were calculated and compared to the EECs for chronic exposure of acetamiprid in ground and surface water. After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect short-term aggregate exposure to exceed the Agency's level of concern, as shown in the following Table 6:

e N/A = Not Applicable

4. Aggregate cancer risk for U.S. population. The Agency classified acetamiprid into the category not likely to be carcinogenic to humans based on the absence of a dose-response and a lack of a statistically significant increase in the mammary adenocarcinoma incidence by pair-wise comparison of the mid- and high-dose groups with the controls. Although the incidence exceeded the laboratories historical control data from the same lab: the increase was within the range of values from the supplier.

5. 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, and to infants and children from aggregate exposure to acetamiprid residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Enforcement methods are available for vegetable and non-citrus crops, citrus crops, and livestock commodities. Citrus and livestock methods consist of solvent extraction, followed by solid-phase cleanup, and high performance liquid chromatography/ultraviolet determination of residues. The vegetable and non-citrus crop method differs in that it employs gas chromatography/Start Printed Page 14658electron capture detection determination of residues. The livestock method analyzes acetamiprid and IM-2-1 simultaneously. Limits of quantitation are 0.01 ppm for vegetable and non-citrus fruits, meat, milk, fat, and eggs; and 0.05 ppm for citrus and meat byproducts. Adequate radiovalidation and independent laboratory validation (ILV) data have been received and the method was forwarded to the Analytical Chemistry Laboratory (ACL) for petition method validation (PMV). The petitioner will be required to make any modifications or revision to the proposed enforcement method resulting from PMV. When the PMV is finalized, the method may be requested from: Calvin Furlow, PRRIB, IRSD (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW, Washington, DC 20460; telephone number: (703) 305-5229; e-mail address: furlow.calvin@epa.gov.

B. International Residue Limits

There are no CODEX, Canadian, or Mexican Maximum Residue Limits for acetamiprid in or on citrus fruit group, citrus dried pulp, cotton, fruiting and leafy, leafy vegetables, tomato paste; and for the combined residues of acetamiprid and IM-2-1 N1-[(6-chloro-3-pyridyl) in or on fat, meat, and meat byproducts of cattle, goat, hog, horse, and sheep; milk; poultry eggs, fat, liver, and meat.

C. Conditions

The conditions of the acetamiprid registration contained the following confirmatory data and label requirements: rotational crop storage stability; and radiovalidation data for IM-2-1-amide in ruminant muscle. The storage stability data is considered confirmatory data since the Agency has examined other storage stability data of acetamiprid and found it to be stable upon storage. The Agency decided to impose tolerances on meat and poultry products upon review of the data although tolerances for IM-2-1 were not considered by the registrant in the original submission.

V. Conclusion

Therefore, tolerances are established for residues of acetamiprid N1-[(6-chloro-3-pyridyl) methyl]-N2-cyano-N1-methylacetamidine in or on citrus fruit group, citrus dried pulp, cotton undelinted seed, cotton gin byproducts, fruiting vegetable group, grape, leafy vegetable group (except brassica), leafy vegetable brassica group, pome fruit group, and tomato paste; and tolerances for the combined residues of acetamiprid and IM-2-1 N1-[(6-chloro-3-pyridyl) methyl]-N2-cyano-acetamidine in or on fat, meat, and meat byproducts of cattle, hog, horse, goat, and sheep; milk; eggs; fat, liver and meat of poultry.

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 of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) 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), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days.

A. What Do I Need to Do to File an Objection or Request a Hearing?

Do not include any CBI in your electronic copy. 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. Regulatory Assessment Requirements

This final rule establishes a tolerance under FFDCA section 408(d) 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 FFDCA section 408(d), 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 FFDCA section 408(n)(4). 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.

VIII. Submission to Congress and the Comptroller General

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).
