II. Summary of Petitioned-For Tolerance

In the Federal Register of May 18, 2018 (83 FR 23247) (FRL-9976-87), 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 7F8612) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, North Carolina 27709-3528. The petition requested to establish tolerances in40 CFR part 180for residues of the fungicide mefentrifluconazole (BAS 750 F); 2-[4-(4-chlorophenoxy)-2-(trifluoromethyl)phenyl]-1-(1 H-1,2,4-triazole-1-yl)propan-2-ol] in or on the following raw agricultural commodities: almond, hulls at 4 parts per million (ppm); barley, hay at 15 ppm; barley, straw at 30 ppm; cattle, fat at 0.3 ppm; Start Printed Page 30940cattle, kidney at 0.2 ppm; cattle, liver at 0.5 ppm; cattle, meat at 0.09 ppm; cattle, muscle at 0.04 ppm; cereal grains crop group 15, except wheat and corn at 3 ppm; cherry subgroup 12-12A at 4 ppm; citrus, oil at 30 ppm; corn, aspirated grain fractions at 0.3 ppm; corn, field, grain at 0.01 ppm; corn, field, stover at 9 ppm; corn, sweet, forage at 6 ppm; corn, sweet, grain at 0.02 ppm; corn, sweet, stover at 6 ppm; foliage of legume vegetables, except soybean, crop subgroup 7A at 20 ppm; forages of cereal grains, crop group 16 at 4 ppm; goat, fat at 0.3 ppm; goat, kidney at 0.2 ppm; goat, liver at 0.5 ppm; goat, meat at 0.09 ppm; goat, muscle at 0.04 ppm; grape, raisin at 4 ppm; grapefruit subgroup 10-10C at 1 ppm; horse, fat at 0.3 ppm; horse, kidney at 0.2 ppm; horse, liver at 0.5 ppm; horse, meat at 0.09 ppm; horse, muscle at 0.04 ppm; legume vegetables (succulent or dried) crop group 6, except lentil at 0.1 ppm; lemon/lime subgroup 10-10B at 2 ppm; lentil, dry at 2 ppm; milk at 0.03 ppm; orange subgroup 10-10A at 1 ppm; peach subgroup 12-12B at 2 ppm; peanut at 0.01 ppm; peanut, hay at 30 ppm; plum prune, fresh at 4 ppm; plum subgroup 12-12C at 2 ppm; pome fruit crop group 11-10 at 1.5 ppm; poultry, eggs at 0.01 ppm; poultry, fat at 0.01 ppm; poultry, liver at 0.01 ppm; poultry, meat at 0.01 ppm; poultry, muscle at 0.01 ppm; poultry, skin at 0.01 ppm; rapeseed subgroup 20A at 1 ppm; rice, straw at 9 ppm; sheep, fat at 0.3 ppm; sheep, kidney at 0.2 ppm; sheep, liver at 0.5 ppm; sheep, meat at 0.09 ppm; sheep, muscle at 0.04 ppm; small fruit vine climbing, except fuzzy kiwifruit subgroup 13-07F at 1.5 ppm; sorghum, stover at 9 ppm; soybean, aspirated grain fractions at 5 ppm; soybean, forage at 4 ppm; soybean, hay at 15 ppm; soybean, seed at 0.3 ppm; sugar beet at 0.6 ppm; sugar beet, top at 9 ppm; swine, fat at 0.01 ppm; swine, liver at 0.01 ppm; swine, meat at 0.01 ppm; swine, skin at 0.01 ppm; tree nut crop group 14-12 at 0.06 ppm; tuberous and corm vegetables subgroup 1C at 0.02 ppm; wheat, aspirated grain fractions at 20 ppm; wheat, grain at 0.4 ppm; wheat, hay at 8 ppm; and wheat, straw at 30 ppm. That document referenced a summary of the petition prepared by BASF, the registrant, which is available in the docket,http://www.regulations.gov. Comments were received on the notice of filing; however, they were not related to mefentrifluconazole.

Following revisions to that petition, EPA published another notice of filing, which supersedes the May 18, 2018 document. That document was published in the Federal Register of March 18, 2019 (84 FR 9735) (FRL-9989-90). The tolerances requested were the same, except for the following: (1) The new petition sought two new tolerances, one for residues on corn, pop, grain at 0.01 ppm and one for residues on grain, cereal, forage, fodder, and straw, group 16, stover at 9 ppm; and (2) the new petition dropped the request for the separate stover tolerances for corn, field, stover at 9 ppm; corn, sweet, stover at 6 ppm; and sorghum, stover at 9 ppm, as those would be subsumed in the group 16, stover tolerance. The amended summary of the petition prepared by BASF, the registrant, and referenced in that document, is available in the docket,http://www.regulations.gov. Comments were received on the notice of filing; however, they were not related to mefentrifluconazole.

based upon review of the data supporting the petition and under its authority in FFDCA section 408(d)(4)(A)(i), EPA is establishing tolerances that vary slightly from what the petitioner sought. The reason 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 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 mefentrifluconazole including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with mefentrifluconazole 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 liver was the most consistent target organ across species, with mice being the most sensitive species. Following subchronic and chronic exposures, increased absolute and relative liver weights, and histopathological liver findings (subchronic: hypertrophy, cytoplasmic alteration, and necrosis in males; fatty change in females; chronic: diffuse and macrovesicular fatty changes) were observed in both sexes. Decreased cholesterol was also observed in the mouse subchronic toxicity studies (cholesterol was not measured in the mouse carcinogenicity study). Following oral exposures to rats, there were effects on liver function as evidenced by increased alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and cholesterol, increased absolute and relative liver weights, and histopathological findings (hepatocellular hypertrophy (subchronic and chronic), multifocal necrosis (females; subchronic)). In dogs, liver effects included increased ALP, increased liver weights, and histopathological findings in the liver (hepatocellular hypertrophy, eosinophilic change, and subcapsular fibrosis). In the 90-day oral toxicity study in dogs, males were more sensitive than females; however, in the 1-year toxicity study, effects were observed at the same dose for both sexes. The toxicity was also shown to progress, with greater increases in ALP along with fibrosis being observed in the chronic study. Other effects included increased white blood cell (WBC) counts in mice following subchronic exposures. In addition, increased adrenal gland weights were noted in male rats following subchronic exposures and in female rats, dogs, and mice following chronic exposures; however, corresponding histopathological findings (eosinophilic cytoplasmic change) were only noted in the adrenal glands of female mice in the carcinogenicity study. An in vitro human recombinant aromatase assay Start Printed Page 30941conducted with mefentrifluconazole indicates that it has the potential to interact with the aromatase enzyme.

There was no evidence of increased quantitative or qualitative fetal susceptibility in the developmental toxicity studies in rats and rabbits or offspring susceptibility in the two-generation reproduction toxicity studies in rats. In the developmental toxicity study in rats, fetal effects (increased placental weight, decreased fetal weight, increased incidence of dilated renal pelvis) occurred at the same dose as maternal effects (increased placental weight). In the developmental toxicity study in rabbits, no maternal or developmental effects were seen up to the highest dose tested (25 mg/kg/day); 50 mg/kg/day was established as the maximum tolerable dose (MTD) for non-pregnant female rabbits in the range-finding studies. In the two-generation reproduction study in rats; offspring effects (decreased pup body weight, increased total litter loss and litters containing pup death during post-natal day (PND) 1-4, and increased incidence of dilated renal pelvis) occurred at the same dose as those eliciting parental toxicity (changes in clinical chemistry parameters (increased ALP, GGT, triglycerides, cholesterol), increased relative liver weights, histopathological findings in the liver, and increased total litter loss and litters containing pup death during PND 1-4). Reproductive toxicity (decreased implantation sites per dam in the F1 generation maternal animals) was observed at the same dose causing parental and offspring effects.

In the acute neurotoxicity study in rats, unsteady gait, increased foot splay, and decreased motor activity were observed at 2,000 mg/kg (no-observed-adverse-effect-level (NOAEL) = 600 mg/kg) for both sexes. However, there is no other evidence of neurotoxicity in the database. In addition, there were no treatment-related histopathological findings in the central or peripheral nervous system in the toxicological database.

Mefentrifluconazole was categorized as having low acute toxicity via the oral, dermal, and inhalation routes (Toxicity Categories III-IV). It is a not an eye or skin irritant (Toxicity Category IV), but it is a dermal sensitizer.

M750F022 is a metabolite that was identified as a residue of concern in the livestock metabolism studies and has a hydroxyl group instead of the triazole ring as a result of cleavage. In the available rat metabolism data, M750F022 was not found at significant amounts; however, it is a proposed intermediate for several metabolites that were observed in the study. Additional toxicological studies were performed, which demonstrated that M750F022 was of low acute toxicity by the oral route in rats. There was no genotoxic concern identified in three in vitro genotoxicity assays. In a 28-day oral toxicity study in mice, the liver was identified as the target organ. M750F022 showed considerably lower potential for aromatase inhibition than the parent, mefentrifluconazole, in an in vitro aromatase inhibition assay. based on these studies, M750F022 is not considered to be a greater toxicological concern than mefentrifluconazole.

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, seehttp://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?assessing-human-health-risk-pesticides.

A summary of the toxicological endpoints for mefentrifluconazole used for human risk assessment is shown in the Table of this unit.

Table��Summary of Toxicological Doses and Endpoints for Mefentrifluconazole for Use in Human Health Risk Assessment

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to mefentrifluconazole, EPA considered exposure under the petitioned-for tolerances. EPA assessed dietary exposures from mefentrifluconazole 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.

No such effects were identified in the toxicological studies for the general population for mefentrifluconazole; therefore, a quantitative acute dietary exposure assessment for the general population is unnecessary.

However, such effects were identified for mefentrifluconazole for females 13 to 49 years old. In estimating acute dietary exposure, EPA used 2003-2008 food consumption information from the U.S. Department of Agriculture's National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in food, EPA conducted an unrefined acute dietary exposure and risk assessment assuming 100 percent crop treated (PCT), default processing factors, and tolerance-level residues for all food commodities.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used 2003-2008 food consumption data from the USDA's NHANES/WWEIA. As to residue levels in food, EPA conducted a partially refined chronic dietary exposure and risk assessment assuming 100 PCT, empirical processing factors (when available), and average field-trial residues for some commodities.

iii. Cancer. A cancer dietary exposure and risk assessment was not conducted for mefentrifluconazole as it was classified as ��Not likely to be Carcinogenic to Humans�� based on the absence of treatment-related tumors in two adequate rodent carcinogenicity studies.

iv. Anticipated residue and PCT 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 screening level water exposure models in the dietary exposure analysis and risk assessment for mefentrifluconazole in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of mefentrifluconazole. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found athttp://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?about-water-exposure-models-used-pesticide.

based on the Pesticide in Water Calculator (PWC), the estimated drinking water concentrations (EDWCs) of mefentrifluconazole for acute exposures are estimated to be 42.3 parts per billion (ppb) for surface water and 30.3 ppb for ground water, and for chronic exposures are estimated to be 18.4 ppb for surface water and 5.1 ppb for ground water.

Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For the acute dietary risk assessment, the water concentration value of 42.3 ppb was used to assess the contribution to drinking water and for the chronic dietary risk assessment, the water concentration of value 18.4 ppb was used to assess the contribution to drinking water.

3. From non-dietary exposure. The term ��residential exposure�� is used in Start Printed Page 30943this 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).

Mefentrifluconazole is proposed to be registered for the following uses that could result in residential exposures: non-residential turf (i.e., golf courses). EPA assessed residential exposure using the following assumptions: Residential handler exposures are not anticipated based on the proposed use sites and therefore have not been quantitatively assessed. There is the potential for post-application exposure for individuals exposed as a result of being in an environment that has been previously treated with mefentrifluconazole. Short-term dermal exposures were assessed for adults, youth 11 to less than 16 years old, and children 6 to less than 11 years old.

The residential exposure scenario used in both the adult aggregate assessment and the children 6 to <11 years old aggregate assessment is from post-application dermal exposure after applications to golf courses from golfing activities. These scenarios for aggregation, adults and children (6 to <11 years old), represent the worst-case risk estimates and are protective of all other lifestages and exposure scenarios.

Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found athttp://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.��

Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to mefentrifluconazole and any other substances; the Agency's previous statements regarding the potential for a common mechanism among the conazoles noted that the underlying data available at the time were inconclusive. Although the conazole fungicides (triazoles) produce 1,2,4 triazole and its acid-conjugated metabolites (triazolylalanine and triazolylacetic acid), 1,2,4 triazole and its acid-conjugated metabolites do not contribute to the toxicity of the parent conazole fungicides (triazoles). The agency has assessed the aggregate risks from the 1,2,4 triazole and its acid-conjugated metabolites (triazolylalanine and triazolylacetic acid) separately. The supporting risk assessment concludes that aggregate risks are below the Agency's level of concern and can be found athttp://www.regulations.govin the document titled ��Common Triazole metabolites: Updated Aggregate Human Health Risk Assessment to Address New Section 3 Registrations For Use of Difenoconazole and Mefentrifluconazole�� in docket ID number EPA-HQ-OPP-2018-0002. Mefentrifluconazole does not appear to produce any other toxic metabolite produced by other substances. For the purposes of this action, therefore, EPA has not assumed that mefentrifluconazole has a common mechanism of toxicity with other substances.

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 evidence of increased quantitative or qualitative fetal susceptibility in the developmental toxicity studies in rats and rabbits or offspring susceptibility in the two-generation reproduction toxicity studies in rats.

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 existing toxicological database for mefentrifluconazole is adequate for FQPA evaluation. Developmental toxicity studies in rats and rabbits as well as a two-generation reproduction study in rats are available for FQPA consideration. The Agency has determined, using a weight-of-evidence approach, that the subchronic neurotoxicity, subchronic inhalation toxicity, and immunotoxicity studies are not required at this time.

ii. In the acute neurotoxicity study in rats, unsteady gait, increased foot splay, and decreased motor activity were considered adverse at 2,000 mg/kg (NOAEL = 600 mg/kg). However, concern is low since the effects are characterized by clear NOAEL and LOAEL values, there is no other evidence of neurotoxicity in the database, there were no corroborating histopathological findings in the central or peripheral nervous system, and the effects were seen at a dose that is not considered relevant for human health risk assessment.

iii. There is no evidence that mefentrifluconazole results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the two-generation reproduction study.

iv. There are no residual uncertainties identified in the exposure databases. The dietary assessment is based on high-end assumptions, assuming 100 PCT, and average field trial residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to mefentrifluconazole in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children. These assessments will not underestimate the exposure and risks posed by mefentrifluconazole.

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 mefentrifluconazole will occupy 2.2% of the aPAD for females 13 to 49 years old, the only population group of concern.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to mefentrifluconazole from food and water will utilize 19% of the cPAD for Start Printed Page 30944children 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 residential exposure to residues of mefentrifluconazole 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).

Mefentrifluconazole 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 mefentrifluconazole.

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 2,600 for adults and 1,900 for children 6 to less than 11 years old. Because EPA's level of concern for mefentrifluconazole is a MOE of 100 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, mefentrifluconazole 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 mefentrifluconazole.

5. Aggregate cancer risk for U.S. population. based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, mefentrifluconazole is not expected to pose a cancer risk to humans.

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 mefentrifluconazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

The registrant, BASF, has proposed a Quick Easy Cheap Effective Rugged and Safe (QuEChERS) multi-residue method (BASF method L0295/01) for the determination of mefentrifluconazole residues in plant matrices. BASF Analytical Method No. L0272/01 is proposed as the enforcement method for the determination of residues of mefentrifluconazole in livestock commodities by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS).

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: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 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.

The Codex has not established any MRLs for mefentrifluconazole.

C. Revisions to Petitioned-For Tolerances

Under FFDCA section 408(d)(4)(A)(i), EPA may establish tolerances that vary from those sought by the petition. For consistency in nomenclature, EPA has used the Agency's preferred commodity terms for the commodities for which tolerances were requested. In addition, the levels at which several tolerances are being established vary from the original petition due to differences in how tolerance values were calculated. Finally, EPA is establishing tolerances for processed commodities where residues concentrate in commodities for which tolerances are being established. A summary and rationale behind these modifications can be found athttp://www.regulations.govin the document titled ��Mefentrifluconazole. Human Health Risk Assessment for the Section 3 Registration Action of the New Active Ingredient on Non-Residential Turf, Sod Farms, Ornamentals, Commercial and On-Farm Seed Treatment; and Pome Fruit, Crop Group 11-10; Stone Fruit, Crop Group 12-12; Tree Nuts, Crop Group 14-12; Cereal Grains, Crop Group 15; Legume Vegetables, Crop Group 6; Foliage of Legume Vegetables, Crop Group 7; Citrus Fruit, Crop Group 10-10; Small Fruit Vine Climbing, Except Fuzzy Kiwifruit Subgroup 13-07F; Soybeans; Peanuts; Sugar Beet; Rapeseed Subgroup 20A; and Tuberous and Corm Vegetables Subgroup 1C�� on pages 10-13 in docket ID number EPA-HQ-OPP-2018-0002.

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 toExecutive Order 13211,entitled ��Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use�� (66 FR 28355, May 22, 2001) orExecutive Order 13045,entitled ��Protection of Children from Environmental Health Risks and Safety Risks�� (62 FR 19885, April 23, 1997), nor is it considered a regulatory action underExecutive Order 13771,entitled ��Reducing Regulations and Controlling Regulatory Costs�� (82 FR 9339, February 3, 2017). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501et seq.), nor does it require any special considerations underExecutive 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 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. 601et 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 thatExecutive Order 13132,entitled ��Federalism�� (64 FR 43255, August 10, 1999) andExecutive 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. 1501et 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. 272note).

VII. Congressional Review Act

Pursuant to the Congressional Review Act (5 U.S.C. 801et 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 by5 U.S.C. 804(2).
