That notice referenced a summary of the petition prepared by Bayer CropScience LP in c/o Nichino America, Inc. (U.S. subsidiary of Nihon Nohyaku Co., Ltd.), the registrant, which is available in the docket at https://www.regulations.gov. There were no substantive comments received in response to the notice of filing. Based upon review of the data supporting the referenced petition, EPA has revised the numerical level for several of the petitioned-for tolerances for flubendiamide, and is also revoking several now superseded tolerances. The reasons for these changes are explained in Unit IV.C. III. Aggregate Risk Assessment and Determination of Safety Section 408(b)(2)(A)(i) of 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 FFDCA 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) of 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.* * *’’ Consistent with section 408(b)(2)(D) of FFDCA, and the factors specified in PO 00000 Frm 00072 Fmt 4700 Sfmt 4700 section 408(b)(2)(D) of 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 for flubendiamide including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with flubendiamide 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 first human health risk assessment for flubendiamide (April 3, 2008) was conducted for uses on corn, cotton, tobacco, tree fruit, tree nuts, vine crops, and vegetable crops. Since that time, no new toxicology data has been submitted to the Agency. The following summary represents all the salient features regarding hazard characterization and endpoint selection for flubendiamide. Flubendiamide has a low acute toxicity via the oral, dermal and inhalation routes of exposure. Though it is a slight irritant to the eye, flubendiamide is not a skin irritant and it is not a skin sensitizer under the conditions of the guinea pig maximization test. In the mammalian toxicology database, the primary target organ of flubendiamide exposure is the liver, with secondary effects reported in the thyroid and kidney at equivalent or higher doses; no-observed-adverseeffect-levels (NOAELs) established to protect for liver toxicity are protective of effects seen in the thyroid and kidney. Adverse adrenal effects were also noted in the dog. Buphthalmia (eye enlargement), opacity, and exophthalmus with hemorrhage appearing only in infancy, were observed in rat offspring in the reproductive and developmental neurotoxicity (DNT) studies. There was no clear dose-response relationship for this effect but ocular toxicity was noted in three rat studies and accompanied by histopathological findings of synechia, hemorrhage, keratitis, iritis, and cataracts. Therefore, bupthalmos is considered an effect of treatment. No evidence of cancer was seen for flubendiamide in cancer bioassays in mice and rats. Flubendiamide was also negative in mutagenicity testing. E:\FR\FM\23MRR1.SGM 23MRR1 Federal Register / Vol. 76, No. 56 / Wednesday, March 23, 2011 / Rules and Regulations Accordingly, flubendiamide was classified as ‘‘Not Likely To Be Carcinogenic to Humans.’’ More detailed information on the studies received and the nature of the adverse effects caused by flubendiamide as well as the NOAEL and the lowestobserved-adverse-effect-level (LOAEL) from the toxicity studies can be found in the document entitled, ‘‘Flubendiamide: Human Health Risk Assessment for Proposed Uses on Corn, Cotton, Tobacco, Tree Fruit, Tree Nuts, Vine crops and Vegetable Crops,’’ dated April 3, 2008, by going to https:// www.regulations.gov.

Toxicological Points of Departure/ Levels of Concern Once a pesticide’s toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern (LOC) to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which the NOAEL and the lowest dose at which adverse effects of concern are identified (the LOAEL). Uncertainty/safety factors are used in 16303 conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose (PAD) (a = acute, c = chronic) or a reference dose (RfD)—and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https:// www.epa.gov/pesticides/factsheets/ riskassess.htm. A summary of toxicological endpoints for flubendiamide used for human risk assessment is shown in Table 1 of this unit.

Double-click on the document to view the referenced information on pages 37– 38 of 105. C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to flubendiamide, EPA considered exposure under the petitioned-for tolerances as well as all existing flubendiamide tolerances in 40 CFR 180.639. Acute and chronic dietary (food and drinking water) exposure PO 00000 Frm 00073 Fmt 4700 Sfmt 4700 assessments were conducted using the Dietary Exposure Evaluation Model, Version 2.03—Food Commodity Intake Database (DEEM–FCIDTM) which uses food consumption information from the United States Department of Agriculture’s (USDA) 1994–1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). EPA assessed dietary exposures from flubendiamide in food for the proposed new uses as follows: i. Acute exposure. Quantitative acute dietary exposure and risk assessments E:\FR\FM\23MRR1.SGM 23MRR1 erowe on DSK5CLS3C1PROD with RULES 16304 Federal Register / Vol. 76, No. 56 / Wednesday, March 23, 2011 / Rules and Regulations are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure. Such effects were identified for flubendiamide. In estimating acute dietary exposure, EPA used DEEM– FCIDTM along with food consumption information from the USDA 1994–1996 and 1998 CSFII. As to residue levels in food, for the acute assessment, the modeled exposure estimates are based on tolerance level residues, assuming 100% of crops were treated. In addition, experimental processing (where available) factors were assumed for both registered and requested crop uses. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used DEEM–FCIDTM along with the food consumption data from the USDA 1994–1996 and 1998 CSFII. As to residue levels in food, EPA assumed a subset of the currently registered crops contain residues at the average residue levels found in the crop field trials. For the newly proposed crops, livestock commodities, and the remaining currently registered crops, EPA assumed tolerance level residues. In addition, experimental processing factors were used where available. Finally, EPA assumed 100% of crops were treated. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that flubendiamide should be classified as ‘‘Not Likely To Be Carcinogenic to Humans.’’ As a result, a cancer dietary exposure assessment for the purpose of assessing cancer risk is unnecessary for flubendiamide, and was not conducted. iv. Anticipated residue information. Section 408(b)(2)(E) of 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 residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) 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. For the present action, EPA will issue such data call-ins as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than 5 years from the date of issuance of these tolerances. 2. Dietary exposure from drinking water. The Agency used Tier II screening level water exposure models in the dietary exposure analysis and risk assessment for flubendiamide in drinking water. These simulation VerDate Mar<15>2010 15:27 Mar 22, 2011 Jkt 223001 models take into account data on the physical, chemical and fate/transport characteristics of flubendiamide. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www.epa.gov/oppefed1/models/ water/index.htm. Flubendiamide is persistent and potentially mobile in terrestrial and aquatic environments. These fate properties suggest that it has a potential to move into surface water and ground water. The Agency has completed a drinking water assessment for flubendiamide using screening level water exposure models that were based on the existing and proposed uses. For the 1-in-10-year peak, the highest Tier 2 Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/ EXAMS) Estimated Drinking Water Concentrations (EDWC) for flubendiamide was 24.57 parts per billion (ppb), based on application to corn. For the 1-in-10-year annual average, the highest PRZM/EXAMS EDWC was 11.46 ppb, also based on application to corn. A summary of the dietary exposure from drinking water for flubendiamide used for human risk assessment can be found in the documents entitled, ‘‘Flubendiamide: Human Health Risk Assessment for Proposed Uses on Alfalfa, Globe Artichokes, the Low Growing Berry Subgroup 13–07G (except Cranberry), Peanuts, Pistachios, the Small Fruit Vine Climbing (except Fuzzy Kiwifruit) Subgroup 13–07F, Safflower, Sorghum, Sugarcane, Sunflower, and Turnip Greens, and an Increased Application Rate for Brassica (Cole) Leafy Vegetables,’’ dated November 30, 2010, by going to https:// www.regulations.gov.

Double-click on the document to view the referenced information on page 27 of 62. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Flubendiamide is not registered for any specific use patterns that would result in residential exposure. 4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a PO 00000 Frm 00074 Fmt 4700 Sfmt 4700 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 has not found flubendiamide to share a common mechanism of toxicity with any other substances, and flubendiamide does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that flubendiamide does not have 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 EPA’s Web site at https://www.epa.gov/pesticides/ cumulative. D. Safety Factor for Infants and Children 1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10x) 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 database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA SF. In applying this provision, EPA either retains the default value of 10x, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity. While both the rat and rabbit developmental studies did not identify teratogenic effects and showed no evidence of increased pre-natal susceptibility, adverse eye effects (eye enlargement) were noted in post-natal rat pups older than 14 days in multiple studies (the 2-generation reproduction and 1-generation supplemental studies). Additionally, the DNT study reported eye effects appearing in some offspring between lactation days 14 and 42, even though exposure stopped at lactation day 21, indicating a possible delay (a latent response) from the time of last exposure to onset of bupthalmos. These eye effects did not occur in adult rats. Since the iris and chamber angle are differentiating and specializing into definite structures during post-natal days 5 to 20, neonatal rats appear to have an increased susceptibility to flubendiamide exposure as compared to adults. E:\FR\FM\23MRR1.SGM 23MRR1 erowe on DSK5CLS3C1PROD with RULES Federal Register / Vol. 76, No. 56 / Wednesday, March 23, 2011 / Rules and Regulations In addition to the reported eye effects in the DNT study, there was also a balano-preputial separation (separation of the prepuce (foreskin) from the glans penis (balanus)) delay. While this effect is generally considered adverse per se, it is not assumed to be a developmental effect from in utero exposure. Here, delayed balano-preputial separation is considered secondary to reduced postnatal pup body weight as a result of post-natal exposure. Furthermore, it was resolved within the appropriate age range of puberty and no effects on reproductive function were observed in the multigeneration study in rats. Delayed balanopreputial separation was seen only at doses causing maternal toxicity and is not more severe than the maternal effects of hepatotoxicity seen at the common pup/maternal LOAEL of the DNT study. Accordingly, the delayed balanopreputial separation seen in the DNT study does not cause concern for increased sensitivity to the young for flubendiamide. Human microsomes have been shown to be capable of approximately 4 times higher hydroxylation rates of flubendiamide as compared to female mouse microsomes and may be able to efficiently metabolize and excrete flubendiamide, preventing accumulation of the parent compound. It remains unclear whether the ability to metabolize and clear the parent compound is the only requirement to avoid ocular toxicity. Due to the potential ocular toxicity, this perinatal ocular effect is considered in the human health risk assessment for flubendiamide. 3. Conclusion. EPA evaluated the quality of the toxicity and exposure data and, based on these data, has determined that the safety of infants and children would be adequately protected if the FQPA SF were reduced to 1x. That decision is based on the following findings: i. The toxicology database for flubendiamide is complete with the exception of a subchronic neurotoxicity study which is now a new data requirement under 40 CFR part 158; however, the existing data are sufficient for endpoint selection for exposure/risk assessment scenarios, and for evaluation of the requirements under the FQPA. Flubendiamide is not a neurotoxic chemical based on neurotoxicity assessments conducted acutely, developmentally and incorporated within the chronic rat study. In several short-term studies in rats (subacute and subchronic feeding, plaque-forming cell assay, one-generation pilot, developmental toxicity) no neurobehavioral signs were observed at VerDate Mar<15>2010 15:27 Mar 22, 2011 Jkt 223001 16305 doses up to and exceeding the limit dose; therefore, an additional database uncertainty factor is not needed to account for potential neurotoxicity. ii. There are no treatment-related neurotoxic findings in the acute neurotoxicity and DNT studies in rats; although eye effects were observed in the DNT study. As noted in Unit III.B., the PODs employed in the risk assessment are protective of this effect. iii. Although susceptibility was identified in the toxicological database (eye effects), the selected regulatory PODs (which are based on clear NOAELs) are protective of these effects; therefore, the human health risk assessment is protective. iv. There are no residual uncertainties identified in the exposure databases and the exposure assessment is protective. The acute dietary food exposure assessment utilizes tolerance-level residues, the chronic dietary food exposure assessment utilizes average residue levels found in the crop field trials/livestock commodities and both assume 100% of crops with requested uses of flubendiamide are treated. The drinking water assessment generated EDWCs using models and associated modeling parameters which are designed to provide conservative, health protective, high-end estimates of water concentrations. The highest relevant EDWCs were used in the dietary (food and drinking water) exposure assessment. By using these screeninglevel exposure assessments in the acute and chronic dietary (food and drinking water) assessments, risk is not underestimated for flubendiamide. consumed over the acute and chronic durations. 1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, EPA has concluded that acute dietary exposure from food and water to flubendiamide will utilize 3.1% of the aPAD for the general U.S. population and 5% of the aPAD for the most highly exposed population subgroup, children aged 1 to 2 years old. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic dietary exposure to flubendiamide from food and water will utilize 20% of the cPAD for the general U.S. population and 58% of the cPAD for the most highly exposed population subgroup, children aged 1 to 2 years old. There are no proposed or existing residential uses for flubendiamide. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of flubendiamide is not expected. 3. Aggregate cancer risk for U.S. population. Based on the data summarized and referenced in Unit III.A., flubendiamide has been classified as ‘‘Not Likely to be Carcinogenic to Humans,’’ and is not expected to pose a cancer risk. 4. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general U.S. population or to infants and children from aggregate exposure to flubendiamide residues. E. Aggregate Risks and Determination of Safety A. Analytical Enforcement Methodology EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD. For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists. For this action, there is potential exposure to flubendiamide from food and drinking water, but not from residential use sites (as there are no proposed or existing residential uses for flubendiamide). Since hazard was identified via the oral route over both the acute and chronic duration, the aggregate risk assessments considers exposures from food and drinking water PO 00000 Frm 00075 Fmt 4700 Sfmt 4700 IV. Other Considerations Adequate enforcement methodology Liquid Chromatography with tandem Mass Spectrometry detection ((LC/MS/ MS), Methods 00816/M002 and 00912) is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Road, Fort Meade, MD 20755–5350; telephone number: (410) 305–2905; e-mail address: residuemethods@epa.gov. B. International Residue Limits In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by section 408(b)(4) of FFDCA. E:\FR\FM\23MRR1.SGM 23MRR1 16306 Federal Register / Vol. 76, No. 56 / Wednesday, March 23, 2011 / Rules and Regulations erowe on DSK5CLS3C1PROD with RULES The Codex Alimentarius is a joint U.N. Food and Agriculture Organization/ World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, section 408(b)(4) of FFDCA requires that EPA explain the reasons for departing from the Codex level. There are currently no MRLs established by Codex, Canada, or Mexico for flubendiamide. C. Revisions To Petitioned-For Tolerances The Agency’s Guidance for Setting Pesticide Tolerances Based on Field Trial Data was utilized for determining appropriate tolerance levels for many raw agricultural commodities (RACs) which showed quantifiable residues in or on samples that were treated according to the proposed use patterns. The following revisions to tolerance levels were made: Based upon review of the data supporting PP 0F7685, recalculated beef and dairy cattle, swine, and poultry dietary burdens, and re-evaluation of previously submitted animal feeding studies, EPA has determined that the established tolerances for residues of flubendiamide for milk fat, and the meat and fat of cattle, goat, horse and sheep should be increased to 1.0 ppm, 0.08 ppm and 0.70 ppm, respectively. For swine (hog), EPA has determined that the proposed tolerances for hog, fat at 0.15 ppm; hog, kidney at 0.06 ppm; hog, liver at 0.06 ppm; and hog, muscle at 0.02 ppm should be established as permanent tolerances for residues of flubendiamide in or on hog, fat at 0.15 ppm, and the proposed tolerances for hog, kidney; hog, liver; and hog, muscle should be increased and established as permanent tolerances for residues of flubendiamide in or on hog, meat and hog, meat byproducts; at 0.15 ppm and 0.03 ppm, respectively. For poultry, EPA has determined that the established tolerances for eggs, fat, liver and meat should be increased to 0.40 ppm, 3.0 ppm, 0.60 ppm and 0.10 ppm, respectively. As part of this regulation, permanent tolerances for residues of flubendiamide in or on alfalfa, forage (25 ppm) and alfalfa, hay (65 ppm) resulting from direct application to the primary crop are being established. These tolerances supersede the currently listed tolerances for indirect or inadvertent residues of flubendiamide in or on alfalfa, forage (0.15 ppm) and alfalfa, hay (0.04 ppm), and; therefore, the indirect/inadvertent VerDate Mar<15>2010 15:27 Mar 22, 2011 Jkt 223001 residue tolerances are being revoked from 40 CFR 180.639(d). V. Conclusion Therefore, new tolerances are being established for residues of flubendiamide [N2-[1,1-dimethyl-2(methylsulfonyl)ethyl]-3-iodo-N1-[2methyl-4-[1,2,2,2-tetrafluoro-1(trifluoromethyl)ethyl]phenyl]-1,2benzenedicarboxamide], in or on artichoke, globe at 1.6 parts per million (ppm); berry, low growing, subgroup 13–07G, except cranberry at 1.5 ppm; fruit, small vine climbing except fuzzy kiwifruit, subgroup 13–07F at 1.4 ppm; hog, fat at 0.15 ppm; hog, meat byproducts at 0.15 ppm; hog, meat at 0.03 ppm; peanut, hay at 60 ppm; peanut, meal at 0.03 ppm; peanut, nutmeat at 0.02 ppm; peanut, refined oil at 0.03 ppm; pistachio at 0.06 ppm; safflower, seed at 5.0 ppm; sorghum, grain, forage at 12 ppm; sorghum, grain, grain at 5.0 ppm; sorghum, grain, stover at 14 ppm; sugarcane, cane at 0.30 ppm; sunflower, seed at 5.0 ppm; and turnip, greens at 25 ppm. The established tolerances for residues of flubendiamide for milk fat, and the meat and fat of cattle, goat, horse and sheep are being increased to 1.0 ppm, 0.08 ppm and 0.70 ppm, respectively. For poultry, the established tolerances for eggs, fat, liver and meat are being increased to 0.40 ppm, 3.0 ppm, 0.60 ppm and 0.10 ppm, respectively. The established tolerances for residues of flubendiamide for brassica, head and stem, subgroup 5A; brassica, leafy greens, subgroup 5B; and grain, aspirated grain fractions are being increased to 3.0 ppm, 25 ppm, and 153 ppm, respectively. The established tolerances for indirect or inadvertent residues of flubendiamide in or on alfalfa, forage (0.15 ppm) and alfalfa, hay (0.04 ppm) are being revoked from 40 CFR 180.639(d), and established as permanent tolerances, in 40 CFR 180.639(a)(2), for residues of flubendiamide in or on alfalfa, forage at 25 ppm; and alfalfa, hay at 65 ppm. VI. Statutory and Executive Order Reviews This final rule establishes tolerances under section 408(d) of 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 final rule has been exempted from review under Executive Order 12866, this final rule is PO 00000 Frm 00076 Fmt 4700 Sfmt 4700 not subject to Executive Order 13211, entitled Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). 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., 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). Since tolerances and exemptions that are established on the basis of a petition under section 408(d) of 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. This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104–4). 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). VII. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801 et seq., generally provides E:\FR\FM\23MRR1.SGM 23MRR1 Federal Register / Vol. 76, No. 56 / Wednesday, March 23, 2011 / Rules and Regulations that before a rule may take effect, the agency promulgating the rule must submit a rule report 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).

in c/o Nichino America, Inc. (U.S. subsidiary of Nihon Nohyaku Co., 
Ltd.), the registrant, which is available in the docket at https://www.regulations.gov. There were no substantive comments received in 
response to the notice of filing.
    Based upon review of the data supporting the referenced petition, 
EPA has revised the numerical level for several of the petitioned-for 
tolerances for flubendiamide, and is also revoking several now 
superseded tolerances. The reasons for these changes are explained in 
Unit IV.C.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of 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 FFDCA 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) of 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.* * 
*''
    Consistent with section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of 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 for flubendiamide including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with flubendiamide 
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 first human health risk assessment for flubendiamide 
(April 3, 2008) was conducted for uses on corn, cotton, tobacco, tree 
fruit, tree nuts, vine crops, and vegetable crops. Since that time, no 
new toxicology data has been submitted to the Agency. The following 
summary represents all the salient features regarding hazard 
characterization and endpoint selection for flubendiamide.
    Flubendiamide has a low acute toxicity via the oral, dermal and 
inhalation routes of exposure. Though it is a slight irritant to the 
eye, flubendiamide is not a skin irritant and it is not a skin 
sensitizer under the conditions of the guinea pig maximization test.
    In the mammalian toxicology database, the primary target organ of 
flubendiamide exposure is the liver, with secondary effects reported in 
the thyroid and kidney at equivalent or higher doses; no-observed-
adverse-effect-levels (NOAELs) established to protect for liver 
toxicity are protective of effects seen in the thyroid and kidney. 
Adverse adrenal effects were also noted in the dog.
    Buphthalmia (eye enlargement), opacity, and exophthalmus with 
hemorrhage appearing only in infancy, were observed in rat offspring in 
the reproductive and developmental neurotoxicity (DNT) studies. There 
was no clear dose-response relationship for this effect but ocular 
toxicity was noted in three rat studies and accompanied by 
histopathological findings of synechia, hemorrhage, keratitis, iritis, 
and cataracts. Therefore, bupthalmos is considered an effect of 
treatment. No evidence of cancer was seen for flubendiamide in cancer 
bioassays in mice and rats. Flubendiamide was also negative in 
mutagenicity testing.

[[Page 16303]]

Accordingly, flubendiamide was classified as ``Not Likely To Be 
Carcinogenic to Humans.''
    More detailed information on the studies received and the nature of 
the adverse effects caused by flubendiamide as well as the NOAEL and 
the lowest-observed-adverse-effect-level (LOAEL) from the toxicity 
studies can be found in the document entitled, ``Flubendiamide: Human 
Health Risk Assessment for Proposed Uses on Corn, Cotton, Tobacco, Tree 
Fruit, Tree Nuts, Vine crops and Vegetable Crops,'' dated April 3,

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern (LOC) to use in evaluating the risk posed by human exposure to 
the pesticide. For hazards that have a threshold below which there is 
no appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which the NOAEL and the lowest dose at which 
adverse effects of concern are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction with the POD to calculate a safe 
exposure level--generally referred to as a population-adjusted dose 
(PAD) (a = acute, c = chronic) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.

human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to flubendiamide, EPA considered exposure under the 
petitioned-for tolerances as well as all existing flubendiamide 
tolerances in 40 CFR 180.639. Acute and chronic dietary (food and 
drinking water) exposure assessments were conducted using the Dietary 
Exposure Evaluation Model, Version 2.03--Food Commodity Intake Database 
(DEEM-FCID\TM\) which uses food consumption information from the United 
States Department of Agriculture's (USDA) 1994-1996 and 1998 Nationwide 
Continuing Surveys of Food Intake by Individuals (CSFII). EPA assessed 
dietary exposures from flubendiamide in food for the proposed new uses 
as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments

[[Page 16304]]

are performed for a food-use pesticide, if a toxicological study has 
indicated the possibility of an effect of concern occurring as a result 
of a 1-day or single exposure. Such effects were identified for 
flubendiamide. In estimating acute dietary exposure, EPA used DEEM-
FCIDTM along with food consumption information from the USDA 
1994-1996 and 1998 CSFII. As to residue levels in food, for the acute 
assessment, the modeled exposure estimates are based on tolerance level 
residues, assuming 100% of crops were treated. In addition, 
experimental processing (where available) factors were assumed for both 
registered and requested crop uses.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used DEEM-FCIDTM along with the food 
consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue 
levels in food, EPA assumed a subset of the currently registered crops 
contain residues at the average residue levels found in the crop field 
trials. For the newly proposed crops, livestock commodities, and the 
remaining currently registered crops, EPA assumed tolerance level 
residues. In addition, experimental processing factors were used where 
available. Finally, EPA assumed 100% of crops were treated.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that flubendiamide should be classified as ``Not Likely To Be 
Carcinogenic to Humans.'' As a result, a cancer dietary exposure 
assessment for the purpose of assessing cancer risk is unnecessary for 
flubendiamide, and was not conducted.
    iv. Anticipated residue information. Section 408(b)(2)(E) of 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 residues that have been measured in food. If EPA relies on 
such information, EPA must require pursuant to FFDCA section 408(f)(1) 
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. For the present action, EPA will 
issue such data call-ins as are required by FFDCA section 408(b)(2)(E) 
and authorized under FFDCA section 408(f)(1). Data will be required to 
be submitted no later than 5 years from the date of issuance of these 
tolerances.
    2. Dietary exposure from drinking water. The Agency used Tier II 
screening level water exposure models in the dietary exposure analysis 
and risk assessment for flubendiamide in drinking water. These 
simulation models take into account data on the physical, chemical and 
fate/transport characteristics of flubendiamide. Further information 
regarding EPA drinking water models used in pesticide exposure 
assessment can be found at https://www.epa.gov/oppefed1/models/water/index.htm.
    Flubendiamide is persistent and potentially mobile in terrestrial 
and aquatic environments. These fate properties suggest that it has a 
potential to move into surface water and ground water. The Agency has 
completed a drinking water assessment for flubendiamide using screening 
level water exposure models that were based on the existing and 
proposed uses. For the 1-in-10-year peak, the highest Tier 2 Pesticide 
Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) 
Estimated Drinking Water Concentrations (EDWC) for flubendiamide was 
24.57 parts per billion (ppb), based on application to corn. For the 1-
in-10-year annual average, the highest PRZM/EXAMS EDWC was 11.46 ppb, 
also based on application to corn.
    A summary of the dietary exposure from drinking water for 
flubendiamide used for human risk assessment can be found in the 
documents entitled, ``Flubendiamide: Human Health Risk Assessment for 
Proposed Uses on Alfalfa, Globe Artichokes, the Low Growing Berry 
Subgroup 13-07G (except Cranberry), Peanuts, Pistachios, the Small 
Fruit Vine Climbing (except Fuzzy Kiwifruit) Subgroup 13-07F, 
Safflower, Sorghum, Sugarcane, Sunflower, and Turnip Greens, and an 
Increased Application Rate for Brassica (Cole) Leafy Vegetables,'' 
dated November 30, 2010, by going to https://www.regulations.gov. The 
referenced document is available in the docket established by this 
action, which is described under ADDRESSES. Locate and click on the

the document to view the referenced information on page 27 of 62.
    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). Flubendiamide is not 
registered for any specific use patterns that would result in 
residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of 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 has not found flubendiamide to share a common mechanism of 
toxicity with any other substances, and flubendiamide does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
flubendiamide does not have 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 EPA's Web site at https://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10x) 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 database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the FQPA SF. In 
applying this provision, EPA either retains the default value of 10x, 
or uses a different additional safety factor when reliable data 
available to EPA support the choice of a different factor.
    2. Prenatal and postnatal sensitivity. While both the rat and 
rabbit developmental studies did not identify teratogenic effects and 
showed no evidence of increased pre-natal susceptibility, adverse eye 
effects (eye enlargement) were noted in post-natal rat pups older than 
14 days in multiple studies (the 2-generation reproduction and 1-
generation supplemental studies). Additionally, the DNT study reported 
eye effects appearing in some offspring between lactation days 14 and 
42, even though exposure stopped at lactation day 21, indicating a 
possible delay (a latent response) from the time of last exposure to 
onset of bupthalmos. These eye effects did not occur in adult rats. 
Since the iris and chamber angle are differentiating and specializing 
into definite structures during post-natal days 5 to 20, neonatal rats 
appear to have an increased susceptibility to flubendiamide exposure as 
compared to adults.

[[Page 16305]]

    In addition to the reported eye effects in the DNT study, there was 
also a balano-preputial separation (separation of the prepuce 
(foreskin) from the glans penis (balanus)) delay. While this effect is 
generally considered adverse per se, it is not assumed to be a 
developmental effect from in utero exposure. Here, delayed balano-
preputial separation is considered secondary to reduced postnatal pup 
body weight as a result of post-natal exposure. Furthermore, it was 
resolved within the appropriate age range of puberty and no effects on 
reproductive function were observed in the multigeneration study in 
rats. Delayed balanopreputial separation was seen only at doses causing 
maternal toxicity and is not more severe than the maternal effects of 
hepatotoxicity seen at the common pup/maternal LOAEL of the DNT study. 
Accordingly, the delayed balanopreputial separation seen in the DNT 
study does not cause concern for increased sensitivity to the young for 
flubendiamide.
    Human microsomes have been shown to be capable of approximately 4 
times higher hydroxylation rates of flubendiamide as compared to female 
mouse microsomes and may be able to efficiently metabolize and excrete 
flubendiamide, preventing accumulation of the parent compound. It 
remains unclear whether the ability to metabolize and clear the parent 
compound is the only requirement to avoid ocular toxicity. Due to the 
potential ocular toxicity, this perinatal ocular effect is considered 
in the human health risk assessment for flubendiamide.
    3. Conclusion. EPA evaluated the quality of the toxicity and 
exposure data and, based on these data, has determined that the safety 
of infants and children would be adequately protected if the FQPA SF 
were reduced to 1x. That decision is based on the following findings:
    i. The toxicology database for flubendiamide is complete with the 
exception of a subchronic neurotoxicity study which is now a new data 
requirement under 40 CFR part 158; however, the existing data are 
sufficient for endpoint selection for exposure/risk assessment 
scenarios, and for evaluation of the requirements under the FQPA. 
Flubendiamide is not a neurotoxic chemical based on neurotoxicity 
assessments conducted acutely, developmentally and incorporated within 
the chronic rat study. In several short-term studies in rats (subacute 
and subchronic feeding, plaque-forming cell assay, one-generation 
pilot, developmental toxicity) no neurobehavioral signs were observed 
at doses up to and exceeding the limit dose; therefore, an additional 
database uncertainty factor is not needed to account for potential 
neurotoxicity.
    ii. There are no treatment-related neurotoxic findings in the acute 
neurotoxicity and DNT studies in rats; although eye effects were 
observed in the DNT study. As noted in Unit III.B., the PODs employed 
in the risk assessment are protective of this effect.
    iii. Although susceptibility was identified in the toxicological 
database (eye effects), the selected regulatory PODs (which are based 
on clear NOAELs) are protective of these effects; therefore, the human 
health risk assessment is protective.
    iv. There are no residual uncertainties identified in the exposure 
databases and the exposure assessment is protective. The acute dietary 
food exposure assessment utilizes tolerance-level residues, the chronic 
dietary food exposure assessment utilizes average residue levels found 
in the crop field trials/livestock commodities and both assume 100% of 
crops with requested uses of flubendiamide are treated. The drinking 
water assessment generated EDWCs using models and associated modeling 
parameters which are designed to provide conservative, health 
protective, high-end estimates of water concentrations. The highest 
relevant EDWCs were used in the dietary (food and drinking water) 
exposure assessment. By using these screening-level exposure 
assessments in the acute and chronic dietary (food and drinking water) 
assessments, risk is not underestimated for flubendiamide.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
aPAD and cPAD. For linear cancer risks, EPA calculates the lifetime 
probability of acquiring cancer given the estimated aggregate exposure. 
Short-, intermediate-, and chronic-term risks are evaluated by 
comparing the estimated aggregate food, water, and residential exposure 
to the appropriate PODs to ensure that an adequate MOE exists.
    For this action, there is potential exposure to flubendiamide from 
food and drinking water, but not from residential use sites (as there 
are no proposed or existing residential uses for flubendiamide). Since 
hazard was identified via the oral route over both the acute and 
chronic duration, the aggregate risk assessments considers exposures 
from food and drinking water consumed over the acute and chronic 
durations.
    1. Acute risk. Using the exposure assumptions discussed in this 
unit for acute exposure, EPA has concluded that acute dietary exposure 
from food and water to flubendiamide will utilize 3.1% of the aPAD for 
the general U.S. population and 5% of the aPAD for the most highly 
exposed population subgroup, children aged 1 to 2 years old.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic dietary 
exposure to flubendiamide from food and water will utilize 20% of the 
cPAD for the general U.S. population and 58% of the cPAD for the most 
highly exposed population subgroup, children aged 1 to 2 years old. 
There are no proposed or existing residential uses for flubendiamide. 
Based on the explanation in Unit III.C.3., regarding residential use 
patterns, chronic residential exposure to residues of flubendiamide is 
not expected.
    3. Aggregate cancer risk for U.S. population. Based on the data 
summarized and referenced in Unit III.A., flubendiamide has been 
classified as ``Not Likely to be Carcinogenic to Humans,'' and is not 
expected to pose a cancer risk.
    4. Determination of safety. Based on these risk assessments, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general U.S. population or to infants and children from 
aggregate exposure to flubendiamide residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology Liquid Chromatography with tandem 
Mass Spectrometry detection ((LC/MS/MS), Methods 00816/M002 and 00912) 
is available to enforce the tolerance expression. The method may be 
requested from: Chief, Analytical Chemistry Branch, Environmental 
Science Center, 701 Mapes Road, Fort Meade, MD 20755-5350; telephone 
number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by section 
408(b)(4) of FFDCA.

[[Page 16306]]

The Codex Alimentarius is a joint U.N. Food and Agriculture 
Organization/World Health Organization food standards program, and it 
is recognized as an international food safety standards-setting 
organization in trade agreements to which the United States is a party. 
EPA may establish a tolerance that is different from a Codex MRL; 
however, section 408(b)(4) of FFDCA requires that EPA explain the 
reasons for departing from the Codex level. There are currently no MRLs 
established by Codex, Canada, or Mexico for flubendiamide.

C. Revisions To Petitioned-For Tolerances

    The Agency's Guidance for Setting Pesticide Tolerances Based on 
Field Trial Data was utilized for determining appropriate tolerance 
levels for many raw agricultural commodities (RACs) which showed 
quantifiable residues in or on samples that were treated according to 
the proposed use patterns. The following revisions to tolerance levels 
were made:
    Based upon review of the data supporting PP 0F7685, recalculated 
beef and dairy cattle, swine, and poultry dietary burdens, and re-
evaluation of previously submitted animal feeding studies, EPA has 
determined that the established tolerances for residues of 
flubendiamide for milk fat, and the meat and fat of cattle, goat, horse 
and sheep should be increased to 1.0 ppm, 0.08 ppm and 0.70 ppm, 
respectively. For swine (hog), EPA has determined that the proposed 
tolerances for hog, fat at 0.15 ppm; hog, kidney at 0.06 ppm; hog, 
liver at 0.06 ppm; and hog, muscle at 0.02 ppm should be established as 
permanent tolerances for residues of flubendiamide in or on hog, fat at 
0.15 ppm, and the proposed tolerances for hog, kidney; hog, liver; and 
hog, muscle should be increased and established as permanent tolerances 
for residues of flubendiamide in or on hog, meat and hog, meat 
byproducts; at 0.15 ppm and 0.03 ppm, respectively. For poultry, EPA 
has determined that the established tolerances for eggs, fat, liver and 
meat should be increased to 0.40 ppm, 3.0 ppm, 0.60 ppm and 0.10 ppm, 
respectively.
    As part of this regulation, permanent tolerances for residues of 
flubendiamide in or on alfalfa, forage (25 ppm) and alfalfa, hay (65 
ppm) resulting from direct application to the primary crop are being 
established. These tolerances supersede the currently listed tolerances 
for indirect or inadvertent residues of flubendiamide in or on alfalfa, 
forage (0.15 ppm) and alfalfa, hay (0.04 ppm), and; therefore, the 
indirect/inadvertent residue tolerances are being revoked from 40 CFR 
180.639(d).

V. Conclusion

    Therefore, new tolerances are being established for residues of 
flubendiamide [N\2\-[1,1-dimethyl-2-(methylsulfonyl)ethyl]-3-iodo-N\1\-
[2-methyl-4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl]phenyl]-1,2-
benzenedicarboxamide], in or on artichoke, globe at 1.6 parts per 
million (ppm); berry, low growing, subgroup 13-07G, except cranberry at 
1.5 ppm; fruit, small vine climbing except fuzzy kiwifruit, subgroup 
13-07F at 1.4 ppm; hog, fat at 0.15 ppm; hog, meat byproducts at 0.15 
ppm; hog, meat at 0.03 ppm; peanut, hay at 60 ppm; peanut, meal at 0.03 
ppm; peanut, nutmeat at 0.02 ppm; peanut, refined oil at 0.03 ppm; 
pistachio at 0.06 ppm; safflower, seed at 5.0 ppm; sorghum, grain, 
forage at 12 ppm; sorghum, grain, grain at 5.0 ppm; sorghum, grain, 
stover at 14 ppm; sugarcane, cane at 0.30 ppm; sunflower, seed at 5.0 
ppm; and turnip, greens at 25 ppm.
    The established tolerances for residues of flubendiamide for milk 
fat, and the meat and fat of cattle, goat, horse and sheep are being 
increased to 1.0 ppm, 0.08 ppm and 0.70 ppm, respectively. For poultry, 
the established tolerances for eggs, fat, liver and meat are being 
increased to 0.40 ppm, 3.0 ppm, 0.60 ppm and 0.10 ppm, respectively.
    The established tolerances for residues of flubendiamide for 
brassica, head and stem, subgroup 5A; brassica, leafy greens, subgroup 
5B; and grain, aspirated grain fractions are being increased to 3.0 
ppm, 25 ppm, and 153 ppm, respectively.
    The established tolerances for indirect or inadvertent residues of 
flubendiamide in or on alfalfa, forage (0.15 ppm) and alfalfa, hay 
(0.04 ppm) are being revoked from 40 CFR 180.639(d), and established as 
permanent tolerances, in 40 CFR 180.639(a)(2), for residues of 
flubendiamide in or on alfalfa, forage at 25 ppm; and alfalfa, hay at 
65 ppm.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under section 408(d) of 
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 final rule has been 
exempted from review under Executive Order 12866, this final rule is 
not subject to Executive Order 13211, entitled Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
Protection of Children from Environmental Health Risks and Safety Risks 
(62 FR 19885, April 23, 1997). 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., 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).
    Since tolerances and exemptions that are established on the basis 
of a petition under section 408(d) of 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.
    This final rule directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of FFDCA. As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled Federalism (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
Consultation and Coordination with Indian Tribal Governments (65 FR 
67249, November 9, 2000) do not apply to this final rule. In addition, 
this final rule does not impose any enforceable duty or contain any 
unfunded mandate as described under Title II of the Unfunded Mandates 
Reform Act of 1995 (UMRA) (Pub. L. 104-4).
    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).

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides

[[Page 16307]]

that before a rule may take effect, the agency promulgating the rule 
must submit a rule report 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).
