Summary of Petitioned-For Tolerance In the Federal Register of June 8, 2017 (82 FR 26641) (FRL-9961- 14), 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 6E8532) by IR-4, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201-W, Princeton, NJ 08540. The petition requested that 40 CFR part 180 be amended by establishing tolerances for residues of the herbicide sulfentrazone in or on Chia, dry seed at 0.15 parts per million (ppm); Teff, forage at 0.50 ppm; Teff, grain at 0.15 ppm; Teff, hay at 0.30 ppm; Teff, straw at 1.5 ppm; Stalk and stem vegetable subgroup 22A at 0.15 ppm; Vegetable, brassica, head and stem, group 5-16 at 0.20 ppm; Brassica, leafy greens, subgroup 4-16B at 0.60 ppm; and Nut, tree, group 14-12 at 0.15 ppm. The petition also requested to remove the tolerances for Asparagus at 0.15 ppm; Brassica, head and stem, subgroup 5A at 0.20 ppm; Brassica, leafy greens, subgroup 5B at 0.40 ppm; Nut, tree, group 14 at 0.15 ppm; [[Page 15978]] Pistachio at 0.15 ppm; and Turnip, tops at 0.60 ppm. That document referenced a summary of the petition prepared by FMC, the registrant, which is available in the docket, http://www.regulations.gov. Comments were received on the notice of filing. EPA's response to these comments is discussed 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 sulfentrazone including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with sulfentrazone 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. Subchronic and chronic toxicity studies in rats, mice, and dogs identified the hematopoietic system as the target of sulfentrazone. Sulfentrazone inhibits the enzyme protoporphyrinogen oxidase (PPO) in target plants, and the results of subchronic and chronic toxicity studies in mammalian systems are consistent with PPO inhibition. Disruption of heme biosynthesis was indicated by signs of anemia, and decreases in hematocrit (Hct), hemoglobin (HGB), and mean corpuscular volume (MCV) in mice, rats, and dogs at comparable dose levels from short- through long-term exposures without a significant increase in severity. Sulfentrazone caused developmental effects when administered via the oral (rats and rabbits) and dermal (rat only) routes of exposure. Developmental effects in rats and rabbits consisted of reductions in the number of implantations in rats, and increases in early resorptions and reduction in live fetuses per litter in rats and rabbits. Surviving rat fetuses exhibited reduced/delayed skeletal ossifications, and decreased fetal body weights. Developmental effects in rats were seen in the absence of maternal toxicity. In contrast with the rat studies, developmental effects in rabbits were observed at a maternally toxic dose, where clinical signs of toxicity included hematuria (red blood cells in urine), abortions, and decreased body-weight gains. In the 2- generation reproductive toxicity study in rats, developmental effects included an increased duration of gestation, reduced prenatal viability (fetal and litter), reduced litter size, and an increased number of stillborn pups. Pup body-weight deficits, along with reduced pup and litter postnatal survival, were also observed. All of the offspring effects were reported in the presence of mild maternal toxicity (decreased body weight and body-weight gain, particularly in F1 females). No systemic toxicity was seen via the dermal route up to the limit dose in a 28-day dermal toxicity study in adult non-pregnant rabbits. In a dermal developmental study in rats, there was an increased quantitative fetal susceptibility. While no maternal effects were observed up to the highest dose tested, fetal effects were observed at this dose, and consisted of decreased body weights, increased incidences of fetal variations, hypoplastic or wavy ribs, incompletely ossified lumbar vertebral arches, incompletely ossified ischia or pubis, and a reduced number of thoracic vertebral and rib ossification sites. In the 26-day inhalation toxicity study, effects that were considered treatment related and adverse occurred only at the highest concentration tested. Systemic effects at this concentration consisted of significant reductions in red blood cell (RBC) parameters in both sexes. Portal-of-entry effects in this study consisted of an increased incidence of minimal nasal respiratory epithelial hyperplasia in both sexes as well as minimal laryngeal epithelial attenuation in all test material exposure groups. The effects on hematological parameters were reversible after 28 days of recovery, while the nasal injury persisted. In an acute neurotoxicity (ACN) study in rats, effects consisted of an increased incidence of clinical signs of toxicity (staggered gait, splayed hind limbs, and abdominal gripping), changes in functional- observation battery (FOB) parameters, and decreased motor activity at a high dose level. Complete recovery was observed by day 14, and there was no evidence of neuropathology. In a rat subchronic neurotoxicity (SCN) study, clinical signs of toxicity, increased motor activity, and/ or decreased body weights, body-weight gain, and food consumption were also observed with no evidence of neuropathology. A published, non- guideline developmental toxicity study in the rat did not conclusively demonstrate developmental neurotoxicity and contained several shortcomings that limit its use for regulatory purposes, including the lack of a no-observed-adverse-effect-level (NOAEL) (DeCastro VL, Destefani CR, Diniz C, Poli P., 2007, Evaluation of neurodevelopmental effects on rats exposed prenatally to sulfentrazone. Neurotoxicology 28(6):1249-59). The reported effects involving measures of physical and reflex development are likely secondary effects reflective of the poor general state of the offspring as reported in the rat two-generation reproductive toxicity study at similar dose levels but with a well- defined NOAEL. In the 28-day rat immunotoxicity study, there were no effects on the immune system and systemic effects consisted of reduced body weight, and increased absolute and relative spleen weights at the highest dose tested. Carcinogenicity studies in rats and mice showed no evidence of increased incidence of tumor formation due to treatment with sulfentrazone, and the EPA has classified sulfentrazone as not likely to be carcinogenic to humans. The available mutagenicity studies indicate that sulfentrazone is weakly clastogenic in the in vitro mouse lymphoma assay in the absence of S9 activation. There is no evidence that sulfentrazone is mutagenic in bacterial cells or clastogenic in male or female mice in vivo. Specific information on the studies received and the nature of the adverse effects caused by sulfentrazone as well as the no-observed- adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect- level (LOAEL) from the [[Page 15979]] toxicity studies can be found at http://www.regulations.gov in the document titled Sulfentrazone--Human Health Risk Assessment for a Section 3 Registration Request to Add New Uses on Chia and Teff; an Amended Use on Mint; and Crop Group Conversions for Tree Nut Group 14- 12, Stalk and Stem Vegetable Subgroup 22A; Vegetable, Brassica, Head and Stem, Group 5-16; and Brassica, Leafy Greens, Subgroup 4-16B on pages 26-31 in docket ID number EPA-HQ-OPP-2017-0072. 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 sulfentrazone used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of September 12, 2014 (79 FR 54620) (FRL-9915-47). C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to sulfentrazone, EPA considered exposure under the petitioned-for tolerances as well as all existing sulfentrazone tolerances in 40 CFR 180.498. EPA assessed dietary exposures from sulfentrazone 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 sulfentrazone and EPA performed separate acute risk assessments for females 13 to 49 years old and for the general population, including infants and children, based on different endpoints and acute population-adjusted doses (aPADs). In estimating acute dietary exposures, EPA used the Dietary Exposure Evaluation Model, Food Consumption Intake Database (DEEM-FCID, ver. 3.16), which incorporates consumption data from United States Department of Agriculture (USDA) National Health and Nutrition Examination Survey, What We Eat in America, NHANES/WWEIA; 2003-2008). As to residue levels in food, EPA assumed tolerance-level residues, 100 percent crop treated (PCT), and DEEM (ver. 7.81) default processing factors. ii. Chronic exposure. In conducting the chronic dietary exposure assessment, EPA used DEEM-FCID, ver. 3.16, which incorporated consumption data from the USDA's NHANES/WWEIA; 2003-2008. As to residue levels in food, EPA assumed tolerance-level residues, 100 PCT, and DEEM (ver. 7.81) default processing factors. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that sulfentrazone does not pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary. iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue or PCT information in the dietary assessment for sulfentrazone. Tolerance-level residues and 100 PCT were assumed for all food commodities. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for sulfentrazone in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of sulfentrazone. 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/Exposure Analysis Modeling System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM GW), the estimated drinking water concentrations (EDWCs) of sulfentrazone for acute exposures are estimated to be 37.3 parts per billion (ppb) for surface water and 134 ppb for ground water; and for chronic exposures for non-cancer assessments are estimated to be 5.3 ppb for surface water and 98 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 134 ppb was used to assess the contribution to drinking water. For the chronic dietary risk assessment, the water concentration of value 98 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). Sulfentrazone is currently registered for the following uses that could result in residential exposures: Residential home lawns/turf and recreational turf, such as golf courses. EPA assessed residential exposures using the following assumptions: Adults were assessed for potential short-term dermal and inhalation handler exposures from applying sulfentrazone to residential turf/home lawns and for short- term post-application dermal exposure from contact with treated residential and recreational turf. Children, ages 11 < 16 years old and 6 < 11 years old, were assessed for post-application dermal exposure from contact with treated residential and recreational turf (home lawns and golf courses). Children, ages 1 < 2 years old, were assessed for post-application short-term dermal and incidental oral exposures (hand-to-mouth, object- to-mouth, and episodic ingestion of granules), as well as short-term incidental oral soil ingestion scenarios from contact with residential turf/home lawns. The recommended adult residential exposure scenario for use in the aggregate assessment reflects short-term dermal exposure from applications to turf via backpack sprayer. The recommended residential exposure scenario for use in the combined short-term aggregate assessment for children ages 1 < 2 years old reflects dermal and hand- to-mouth exposures from post-application exposure to turf applications. This combination should be considered a protective estimate of children's exposure to pesticides used on turf since the incidental oral [[Page 15980]] scenarios are considered inter-related, likely occurring interspersed amongst each other across time; therefore, combining these scenarios would be overly conservative because of the conservative nature of each individual assessment. Further, this scenario is considered protective of potential post-application exposures to children, ages 6 < 11 and 11 < 16 years old, as children 1-2 years old represent the population subgroup for children with the greatest exposure, and is therefore considered protective of other children population subgroups. Intermediate-term exposure is not expected. Chronic exposures are not expected and were not assessed. Finally, residential handler and/or post-application inhalation risk estimates were not combined with dermal or oral risk estimates in the aggregate risk assessment since the toxicological effects in the inhalation toxicological study were portal-of-entry and were different from those seen in the dermal and oral toxicological studies. 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 sulfentrazone to share a common mechanism of toxicity with any other substances, and sulfentrazone does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that sulfentrazone 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 website 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 is evidence of increased quantitative susceptibility following in utero exposure in the oral and dermal rat developmental toxicity studies. Developmental effects, including decreased fetal body weights and reduced/delayed skeletal ossifications, were observed at doses that were not maternally toxic. In the 2-generation reproduction study in rats, offspring effects such as decreased body weights and decreased litter survival were observed at a slightly maternally toxic dose (slightly decreased body-weight gain), indicating possible slightly increased qualitative susceptibility. 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 sulfentrazone is complete. ii. In the ACN and SCN studies, observed effects included changes in motor activity and FOB parameters, clinical signs, and body-weight decrements. There is low concern for neurotoxicity since: 1. Effects were seen at relatively high doses; 2. Effects occurred in the absence of neuropathology; 3. There is no evidence of neurotoxicity in other available studies in the toxicity database; 4. Effects are well-characterized with clearly established NOAEL/ LOAEL values; and 5. The selected PODs are protective of these effects. iii. There was evidence for increased quantitative susceptibility following oral and dermal exposures in the developmental toxicity studies in rats. Although developmental toxicity was observed at lower doses than maternal toxicity in both studies in the rat, the concern is low based on the following considerations: 1. The toxicology database for assessing pre- and postnatal susceptibility is complete; 2. There are clear NOAELs and LOAELs for the developmental effects observed via both the oral and dermal routes; 3. The PODs used for assessing dietary and dermal exposure risks are based on developmental and/or offspring toxicity; 4. The portal-of-entry effects seen in the 26-day inhalation study are protective of the developmental toxicity; and 5. There are no residual uncertainties for pre- and/or postnatal toxicity. 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 sulfentrazone 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 sulfentrazone. 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 sulfentrazone will occupy 1.1% of the aPAD for all infants less than 1-year-old and 6.7% of the aPAD for females 13-49 years old, the population groups 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 sulfentrazone from food and water will utilize 7.0% of the cPAD for children 1-2 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 [[Page 15981]] residues of sulfentrazone 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). Sulfentrazone 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 sulfentrazone. 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 an aggregate MOE of 490 for adults. Because EPA's level of concern for sulfentrazone is a MOE of 100 or below, this MOE is 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, sulfentrazone 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 sulfentrazone. 5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, sulfentrazone 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 sulfentrazone residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology, gas chromatography (GC), 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. No Codex MRLs have been established for sulfentrazone on the crops cited in this document. C. Response to Comments Two comments were received in response to the notice of filing. One was against the establishment of any tolerances for sulfentrazone and the other stated ``deny this application to change the tolerance on this product.'' Although the Agency recognizes that some individuals believe that pesticides should be banned on agricultural crops, the existing legal framework provided by section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA) authorizes EPA to establish tolerances when it determines that the tolerance is safe. Upon consideration of the validity, completeness, and reliability of the available data as well as other factors the FFDCA requires EPA to consider, EPA has determined that these sulfentrazone tolerances are safe. The commenters have provided no information supporting a contrary conclusion. V. Conclusion Therefore, tolerances are established for residues of sulfentrazone in or on Brassica, leafy greens, subgroup 4-16B at 0.60 ppm; chia, seed at 0.15 ppm; nut, tree, group 14-12 at 0.15 ppm; stalk and stem vegetable subgroup 22A at 0.15 ppm; teff, forage at 0.50 ppm; teff, grain at 0.15 ppm; teff, hay at 0.30 ppm; teff, straw at 1.5 ppm; and vegetable, Brassica, head and stem, group 5-16 at 0.20 ppm. In addition, the following existing tolerances are removed as unnecessary since they are superseded by the new tolerances: asparagus; Brassica, head and stem, subgroup 5A; Brassica, leafy greens, subgroup 5B; nut, tree, group 14; pistachio; and turnip, tops. 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), nor is it considered a regulatory action under Executive 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. 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 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 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 [[Page 15982]] 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).
