Summary of Petitioned-For Tolerance In the Federal Register of December 17, 2014 (79 FR 75107) (FRL- 9918-90), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP) 4E8282 by Interregional Research Project Number 4 (IR-4), 500 College Road East, Princeton, NJ 08540. The petition requested that 40 CFR 180.361 be amended by establishing tolerances for residues of the herbicide pendimethalin, [N-(1-ethylpropyl)-3,4-dimethyl-2,6- dinitrobenzenamine], and its metabolite, 4-[(1-ethylpropyl)amino]-2- methyl-3,5-dinitrobenzyl alcohol, in or on caneberry subgroup 13-07A at 0.10 parts per million (ppm) and bushberry subgroup 13-07B at 0.10 ppm, and amending the existing crop group tolerance for nut, tree, group 14 to nut, tree, group 14-12. That document referenced a summary of the petition prepared on behalf of IR-4 by BASF, the registrant, which is available in the docket EPA-HQ-OPP-2014-0397 at http://www.regulations.gov. In the Federal Register of August 26, 2015 (80 FR 51759) (FRL-9931- 74), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP) 4F8261 by BASF Corp., 26 Davis Drive, Research Triangle Park, NC 27709. The petition requested that 40 CFR 180.361 be amended by establishing tolerances for residues of the herbicide pendimethalin, [N-(1- ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine], and its metabolite, 4-[(1-ethylpropyl)amino]-2-methyl-3,5-dinitrobenzyl alcohol, in or on milk at 0.04 parts per million (ppm); cattle, fat at 0.30 ppm; cattle, liver at 1.5 ppm; cattle, meat at 0.1 ppm; cattle, meat byproducts, except liver at 3.0 ppm; goat, fat at 0.30 ppm; goat, liver at 1.5 ppm; goat, meat at 0.10 ppm; goat, meat byproducts, except liver at 3.0 ppm; horse, fat at 0.30 ppm; horse, liver at 1.5 ppm; horse, meat at 0.10 ppm; horse, meat byproducts, except liver at 3.0 ppm; sheep, fat at 0.30 ppm; sheep, liver at 1.5 ppm; sheep, meat at 0.10 ppm; and sheep, meat byproducts, except liver at 3.0 ppm. This petition additionally requested that 40 CFR 180.361 be amended by revising the existing tolerance in or on grass forage, fodder, and hay crop group 17, forage at 1,000 ppm and grass forage, fodder, and hay crop group 17, hay at 2,000 ppm. That document referenced a summary of the petition prepared on behalf of IR-4 by BASF, the registrant, which is available in the docket EPA-HQ-OPP-2014-0397 at http://www.regulations.gov. Two comments were received on these notices of filing. EPA's response to these comments is discussed in Unit IV.C. Based upon review of the data supporting the petition, EPA has revised the petitioned-for tolerance in or on cattle, meat byproduct, meat byproduct except liver, and liver; goat, meat byproduct, meat byproduct except liver, and liver; horse, meat byproduct, meat byproduct except liver, and liver; and sheep, meat byproduct, meat byproduct except liver, and liver. The Agency has determined that the tolerance expression for the ruminant commodities is different than that for plant commodities. Additionally, the EPA is removing existing tolerances for Juneberry; nut, tree, group 14; and pistachio since they are superseded by this action. The reason for these changes are explained in Unit IV.D. 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 FFDCA section 408(b)(2)(D), and the factors specified in FFDCA 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 for pendimethalin including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with pendimethalin 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 target organ for pendimethalin is the thyroid. Thyroid toxicity in chronic and subchronic rat and mouse studies was manifested as alterations in thyroid hormones (decreased total T4, and T3, increased percent of free T4 and T3), increased thyroid weight, and microscopic thyroid lesions (including increased thyroid follicular cell height, follicular cell hyperplasia, as well as follicular cell adenomas). Due to these effects, the Agency required that a developmental thyroid assay be conducted to evaluate the impact of pendimethalin on thyroid hormones, structure, and/or thyroid hormone homeostasis during development. A developmental thyroid study was submitted and demonstrated that there is no potential thyroid toxicity following pre- and/or post-natal exposure to pendimethalin. The points of departure (PODs) used for the chronic and short-term risk assessments were based on co-critical studies of a 92-day thyroid function study in rats, a 56-day thyroid study in rats, and a 14-day intra thyroid metabolism study in rats. An uncertainty factor (UF) of 30X (3X for interspecies extrapolation and 10X for intraspecies variation) is applied for the chronic and short-term risk assessments. The interspecies UF which used to account for animal to human differences in toxicokinetics and toxicodynamics [[Page 79269]] was reduced to 3X due to several important quantitative dynamic differences between rats and humans with respect to thyroid function. A UF of 100X (10X for interspecies extrapolation and 10X for intraspecies variation) was used in the acute risk assessment because the POD was based on an acute neurotoxicity study, not a thyroid study. There is no evidence that pendimethalin is a developmental, reproductive, neurotoxic, or immunotoxic chemical. There is no evidence of increased qualitative or quantitative susceptibility in the young. EPA classified pendimethalin as a ``Group C'', possible human carcinogen based on a statistically significant increased trend and pair-wise comparison between the high-dose group and controls for thyroid follicular cell adenomas in male and female rats. A non- quantitative approach (i.e., non-linear, reference dose (RfD) approach) was used to assess cancer risk since mode-of-action studies are available to demonstrate that the thyroid tumors are due to a thyroid- pituitary imbalance, and also since pendimethalin was shown to be non- mutagenic in mammalian somatic cells and germ cells. Specific information on the studies received and the nature of the adverse effects caused by pendimethalin as well as the no-observed-adverse- effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies can be found at http://www.regulations.gov in document, ``Pendimethalin--Human Health Risk Assessment to Support the Proposed New Uses on the Caneberry Subgroup 13-07A, and the Bushberry Subgroup 13-07B, Amended Use on Grasses and Establishment of Tolerances for Pendimethalin in/on Grass Forage, Fodder, and Hay (Crop Group 17) with New Ruminant Tolerances; Crop Group Conversion for Tree Nut Crop Group 14.'' in pages 14-20 in docket ID number EPA-HQ-OPP-2014-0397. 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 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 no adverse effects are observed (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) 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 http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides. A summary of the toxicological endpoints for Pendimethalin used for human risk assessment is discussed in the final rule published in the Federal Register of August 29, 2012 (77 FR 52240) (FRL-9360-5). C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to pendimethalin, EPA considered exposure under the petitioned-for tolerances as well as all existing pendimethalin tolerances in 40 CFR 180.361. EPA assessed dietary exposures from pendimethalin in food as follows: i. Acute exposure. Quantitative acute dietary exposure and 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 1-day or single exposure. Such effects were identified for pendimethalin. In estimating acute dietary exposure, EPA Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) Version 3.16. This software uses 2003-2008 food consumption data from the U.S. Department of Agriculture's (USDA's) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in food, EPA used tolerance-level residues, and 100 percent crop treated (PCT) for all commodities. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the DEEM-FCID, Version 3.16 software with 2003-2008 food consumption data from the USDA's NHANES/WWEIA. As to residue levels in food, EPA used tolerance-level residues, and 100 percent crop treated (PCT) for all commodities. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that a nonlinear RfD approach is appropriate for assessing cancer risk to pendimethalin. Cancer risk was assessed using the same exposure estimates as discussed in Unit III.C.1.ii., chronic exposure. iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for pendimethalin. Tolerance-level residues and 100 PCT were assumed for all food commodities. 2. Dietary exposure from drinking water. In drinking water, the residue of concern is pendimethalin parent only. The Agency used screening-level water exposure models in the dietary exposure analysis and risk assessment for pendimethalin in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of pendimethalin. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide. Based on the Pesticide Root Zone Model Ground Water (PRZM GW) and Surface Water Concentration Calculator (SWCC) models, the estimated drinking water concentrations (EDWCs) of pendimethalin for acute exposures are estimated to be 96.4 parts per billion (ppb) for surface water and 4.38 x 10-\9\ ppb for ground water. For chronic exposures for non-cancer assessments, they are estimated to be 9.73 ppb for surface water. For acute dietary risk assessment, the water concentration value of 96.4 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 9.73 ppb was used to assess the contribution to drinking 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). Pendimethalin is currently registered for the following uses that could result in residential exposures: Turf, home gardens, and ornamentals. EPA assessed residential exposure using the following assumptions: For handlers, it is assumed that residential use will result in short-term [[Page 79270]] (1 to 30 days) duration dermal and inhalation exposures. Residential post-application exposure is also assumed to be short-term (1-30 days) in duration, resulting from the following exposure scenarios: [cir] Gardening: Adults (dermal) and children 6 < 11 years old (dermal); [cir] Physical activities on turf: Adults (dermal) and children 1-2 years old (dermal and incidental oral); [cir] Mowing turf: Adults (dermal) and children 11 < 16 years old (dermal); and [cir] Exposure to golf courses during golfing: Adults (dermal), children 11 < 16 years old (dermal), and children 6 < 11 years old (dermal). EPA did not combine exposure resulting from adult handler and post- application exposure resulting from treated gardens, lawns, and/or golfing because of the conservative assumptions and inputs within each estimated exposure scenario. The Agency believes that combining exposures resulting from handler and post-application activities would result in an overestimate of adult exposure. EPA selected the most conservative adult residential scenario (adult dermal post-application exposure from gardening) as the contributing source of residential exposure to be combined with the dietary exposure for the aggregate assessment. The children's oral exposure is based on post-application hand-to-mouth exposures. To include exposure from object-to-mouth and soil ingestion in addition to hand-to-mouth would overestimate the potential for oral exposure. However, there is the potential for co- occurrence of dermal and oral exposure, since the toxicological effects from the dermal and oral routes of exposure are the same. As a result, the children's aggregate assessment combines post-application dermal and oral exposure along with dietary exposure from food and water. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide. 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 pendimethalin to share a common mechanism of toxicity with any other substances, and pendimethalin does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that pendimethalin 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 http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides. 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 Safety Factor (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. There was no indication of pre- and/or post-natal qualitative or quantitative increased susceptibility in the developmental studies in rats and rabbits or the 2-generation reproduction studies in rats. A developmental thyroid toxicity study demonstrated that there is no potential thyroid toxicity following pre- and/or post-natal exposure to pendimethalin. 3. Conclusion. EPA has determined that reliable data show 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 toxicity database for pendimethalin is complete. Although a subchronic inhalation study was not available in the database, EPA determined that one is not needed at this time based on a weight-of- evidence analysis, considering the following: (1) All relevant hazard and exposure information, which indicates its low acute inhalation toxicity; (2) its physical/chemical properties, which indicate its low volatility; and (3) the use of an oral POD that results in a residential inhalation margin of exposure (MOE) more than 10X the level of concern (in the case of pendimethalin MOE = 30 based on thyroid POD). ii. There is no indication that pendimethalin is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity. iii. There is no evidence that pendimethalin results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study. In addition, a developmental thyroid toxicity study demonstrated that there is no potential thyroid toxicity following pre- and/or post- natal exposure to pendimethalin. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to pendimethalin in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children as well as incidental oral exposure of toddlers. These assessments will not underestimate the exposure and risks posed by pendimethalin. 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 acute PAD (aPAD) and chronic PAD (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. 1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to pendimethalin will occupy 2% of the aPAD for all infants less than 1 year old, the population group receiving the greatest exposure. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to pendimethalin from food and water will utilize 2.4% of the cPAD for children 1 to 2 years old, the population group receiving the greatest exposure. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic [[Page 79271]] residential exposure to residues of pendimethalin is not expected. 3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Pendimethalin is currently registered for uses that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to pendimethalin. Using the exposure assumptions described in this unit for short- term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 130 for adults and 92 for children 1 to 2 years old, the two population subgroups receiving the greatest combined dietary and non-dietary exposure. Because EPA's level of concern for pendimethalin is a MOE of 30 or below, these MOEs are not of concern. 4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). An intermediate-term adverse effect was identified; however, pendimethalin is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk is assessed based on intermediate-term residential exposure plus chronic dietary exposure. Because there is no intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess intermediate-term risk), no further assessment of intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating intermediate-term risk for pendimethalin. 5. Aggregate cancer risk for U.S. population. As discussed in Unit III.A., EPA has determined that an RfD approach based on the chronic point of departure is appropriate for evaluating cancer risk. As there are not chronic aggregate risks of concern, there are no cancer aggregate risk concerns. 6. Determination of safety. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to pendimethalin residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology, gas chromatography with electron capture detection (GC/ECD), is available to enforce the tolerance expression. The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; email address: [email protected]. 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 FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations 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, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level. There are currently no established Codex MRLs for the residues of pendimethalin. C. Response to Comments Two comments were received to the Notices of Filing for PP 4E8282 and PP 4F8261. One commenter stated: ``Pesticide/Herbicide contents must be made available to the public due to allergies. Labeling foods that have been exposed to Pesticides/Herbicides protects the public from potentially ingesting a known allergen. This safe practice allows health care professionals to determine the cause of a life threatening severe reaction to avoid these products in the future. I am a nurse hence my concern.'' The second commenter stated that no residue should be allowed for pendimethalin and that they do not support manufacture or use of this product. The Agency understands the commenters' concerns and recognizes that some individuals believe that pesticides should be banned on agricultural crops. However, the existing legal framework provided by Section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA) states that tolerances may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. These comments appear to be directed at the underlying statute and not EPA's implementation of it; the citizens have made no contention that EPA has acted in violation of the statutory framework. EPA has found that there is a reasonable certainty of no harm to humans after considering the toxicological studies and the exposure levels of humans to pendimethalin. D. Revisions to Petitioned-for Tolerances Based on review of the data supporting the petitions, EPA has revised the petitioned-for tolerance in or on ``meat byproduct'' (at 3.0 ppm) based on anticipated residues in kidney which contained the highest residue amongst all ruminant tissues and will therefore cover anticipated residues in liver and fat. BASF, proposed setting a tolerance on ``meat byproduct except liver'', also at 3.0 ppm based on anticipated residues in kidney with a separate lower tolerance on liver at 1.5 ppm. However, the anticipated residues in liver versus kidney, on which the tolerance for meat byproduct is based on, are not significantly different given the limited number of data for those tissues and that both are greater than LOQ and within 1 ppm of each other. Therefore, a single tolerance on ``meat byproduct'' without a separate tolerance on liver is adequate. Additionally, the current tolerance expression for pendimethalin for plant commodities includes the combined residues of pendimethalin and its 3,5-dinitrobenzyl alcohol metabolite (CL 202,347). EPA has determined, based on the review of the ruminant feeding study, that the residues of concern for setting tolerances and assessing risks in ruminants is the parent compound, pendimethalin, and its metabolite, 1- (1-ethylpropyl)-5, 6-dimethyl-7-nitro-1H-benzimidazole (also known as metabolite 6). Finally, the Agency is removing Juneberry at 0.1 ppm as it is superseded by fruit, bushberry, subgroup 13-07B; as well as nut, tree, group 14 and pistachio at 0.1 ppm to account for an updated crop group conversion. V. Conclusion Therefore, tolerances are established for plant residues by measuring only the sum of pendimethalin, [N-(1-ethylpropyl)-3,4- dimethyl-2,6-dinitrobenzenamine], and its metabolite, 4-[(1- ethylpropyl)amino]-2-methyl-3,5-dinitrobenzyl alcohol calculated as the [[Page 79272]] stoichiometric equivalent of pendimethalin, in or on bushberry subgroup 13-07B at 0.10 ppm; caneberry subgroup 13-07A at 0.10 ppm; grass forage, fodder, and hay crop group 17, forage at 1,000 ppm; grass forage, fodder, and hay crop group 17, hay at 2,000 ppm; and nut, tree group 14-12 at 0.1 ppm. Tolerances are established for livestock commodities is by measuring only the sum of pendimethalin, [N-(1- ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine], and its metabolite, 1-[(1-ethylpropyl)-5,6-dimethyl-7-nitro-1H-benzimidazole (metabolite 6), calculated as the stoichiometric equivalent of pendimethalin in or on cattle, fat at 0.30 ppm; cattle, meat at 0.10 ppm; cattle, meat byproduct 3.0 ppm; goat, fat at 0.30 ppm; goat, meat at 0.10 ppm; goat, meat byproduct at 3.0 ppm; horse, fat at 0.30 ppm; horse, meat at 0.10 ppm; horse, byproduct at 3.0 ppm; milk at 0.04 ppm; sheep, fat at 0.30 ppm; sheep, meat at 0.10 ppm; and sheep, meat byproduct at 3.0 ppm. Additionally, the existing tolerances for Juneberry; nut, tree, group 14; and pistachio are removed. VI. Statutory and Executive Order Reviews This action establishes tolerances 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 action has been exempted from review under Executive Order 12866, this action 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 action 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 FFDCA section 408(d), such as the tolerances 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 action 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 FFDCA section 408(n)(4). 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 action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). 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 (NTTAA) (15 U.S.C. 272 note). VII. Congressional Review Act Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 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 the rule in the Federal Register. This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).
