Summary of Petitioned-For Tolerance In the Federal Register of February 7, 2017 (82 FR 9555) (FRL–9956–86), 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 6F8457) by ISK Biosciences Corporation, 7470 Auburn Rd., Suite A, Concord, OH 44077. The petition requested that 40 CFR 180.681 be amended by establishing tolerances for residues of the fungicide isofetamid, N[1,1-dimethyl-2-[2-methyl-4-(1methylethoxy)phenyl]-2-oxoethyl]-3methyl-2-thiophenecarboxamide, in or on caneberry subgroup 13–07A at 3.0 parts per million (ppm); apple, wet pomace, at 2.0 ppm; bushberry, subgroup 13–07B at 6.0 ppm; cattle, fat at 0.01 ppm; cattle, meat byproducts at 0.01 ppm; cherry subgroup 12–12A at 5.0 ppm; fruit, pome, group 11–10 at 0.6 ppm; fruit, small vine climbing, except grape, subgroup 13–7E at 9.0 ppm; goat, fat at 0.01 ppm; goat, meat byproducts at 0.01 ppm; horse, fat at 0.01 ppm; horse, meat byproducts at 0.01 ppm; pea and bean, dried shelled, except soybean, subgroup 6C, except cowpea and field pea at 0.05 ppm; pea and bean, succulent shelled, subgroup 6B, except cowpea at 0.04 ppm; peach subgroup 12–12B at 3.0 ppm; plum, prune, dried at 3.5 ppm; plum subgroup 12–12C at 0.8 ppm; sheep, fat at 0.01 ppm; sheep, meat byproducts at 0.01 ppm; and vegetable, legume, edible podded, subgroup 6A at 1.5 ppm. That document referenced a summary of the petition prepared by ISK Biosciences Corporation, the registrant, which is available in the docket, https:// www.regulations.gov. There were no comments received in response to the notice of filing. Based upon review of the data supporting the petition, EPA has revised some of the proposed tolerances; determined that tolerances for residues in livestock commodities are not required; and corrected some of the commodity definitions. 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 VerDate Sep<11>2014 16:55 Jun 13, 2017 Jkt 241001 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 isofetamid including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with isofetamid 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 toxicology database is complete for isofetamid. In repeated dose studies, the liver was the primary target organ in the rat, mouse, and dog, as indicated by increased liver weights, changes in the clinical chemistry values, and liver hypertrophy. A second target organ was the thyroid in the rat and dog, as indicated by changes in thyroid weights and histopathology. Adrenal weight changes were observed in the subchronic rat and dog studies. In the rat and dog, the dose levels where toxicity was observed were similar or higher in the chronic studies compared with the respective subchronic studies, showing an absence of progression of liver toxicity with time. There was no evidence of carcinogenicity in the rat or mouse cancer studies; the mutagenicity battery was negative. There are no genotoxicity, neurotoxicity, or immunotoxicity concerns observed in the available toxicity studies. Developmental toxicity was not observed in the rat or rabbit, and offspring effects such as decreased body PO 00000 Frm 00046 Fmt 4700 Sfmt 4700 weight were seen only in the presence of parental toxicity in the multigeneration rat study. Isofetamid is classified as ‘‘Not Likely to be Carcinogenic to Humans’’ based on the absence of increased tumor incidence in acceptable/guideline carcinogenicity studies in rats and mice. Isofetamid is not acutely toxic; it is classified as Toxicity Category III for acute oral and dermal exposure, and Toxicity Category IV for inhalation exposure. Furthermore, it is not irritating to the eye or skin, and it is not a dermal sensitizer. Specific information on the studies received and the nature of the adverse effects caused by isofetamid as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies are can be found at https://www.regulations.gov in document Isofetamid.

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 E:\FR\FM\14JNR1.SGM 14JNR1 Federal Register / Vol. 82, No. 113 / Wednesday, June 14, 2017 / Rules and Regulations mstockstill on DSK30JT082PROD with RULES degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides. A summary of the toxicological endpoints for isofetamid used for human risk assessment is discussed in Unit III.B. of the final rule published in the Federal Register of July 30, 2015 (80 FR 45440) (FRL–9923–86). C. Exposure Assessment 1. Dietary exposure from food and feed uses. In evaluating dietary exposure to isofetamid, EPA considered exposure under the petitioned-for tolerances as well as all existing isofetamid tolerances in 40 CFR 180.681. EPA assessed dietary exposures from isofetamid 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 isofetamid; therefore, a quantitative acute dietary exposure assessment is unnecessary. ii. Chronic exposure. An unrefined chronic (food and drinking water) dietary assessment was conducted for all registered and proposed food uses of isofetamid using the 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). The chronic dietary (food and drinking water) exposure assessment for isofetamid incorporated existing tolerance-level residues, Agencyrecommended tolerance-level residues for proposed tolerances, DEEM default processing factors, and 100 PCT (percent crop treated). Some tolerance levels were adjusted to include residues of the metabolite, GPTC (a residue of concern for risk assessment). DEEM default processing factors were used for dried apples, apple juice, dried pear, cherry juice, dried apricot, dried peach, plum, prune juice, cranberry juice, and grape juice. The EDWC of 110 VerDate Sep<11>2014 16:55 Jun 13, 2017 Jkt 241001 microgram/Liter (mg/L) was incorporated directly into the dietary assessment. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that isofetamid 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 and/or PCT information in the dietary assessment for isofetamid. Tolerance level residues and/or 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 isofetamid in drinking water. These simulation models take into account data on the physical, chemical, and fate/ transport characteristics of isofetamid. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www2.epa.gov/pesticide-scienceand-assessing-pesticide-risks/aboutwater-exposure-models-used-pesticide. Based on the Pesticide Flooded Application Model and the Pesticide Root Zone Model Ground Water (PRZM GW) the estimated drinking water concentrations (EDWCs) of isofetamid for chronic exposures for non-cancer assessments are estimated to be 110 parts per billion (ppb) for surface water and 43 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic dietary risk assessment, the water concentration value of 110 ppb was used to assess the contribution from drinking water. 3. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Isofetamid is currently registered for the following uses that could result in residential exposures: Turfgrass including golf courses, residential lawns, and recreational turfgrass. It is currently under review for registering use on ornamental plants. The proposed ornamental use is not intended for homeowner use and therefore a quantitative residential handler assessment was not conducted. Additionally, post-application exposures for adults and children are expected to be negligible. However, the existing turf use may result in short- and PO 00000 Frm 00047 Fmt 4700 Sfmt 4700 27151 intermediate-term exposures. Residential exposure may occur by the dermal and incidental oral routes of exposures following the application of isofetamid on residential turf. However, since dermal hazard has not been identified for isofetamid, the only exposure scenario quantitatively assessed is for post-application incidental oral (for children 1 to <2 years old). These exposures have been assessed with current policies, which include the Agency’s 2012 Residential Standard Operating Procedures (https:// www.epa.gov/pesticides/science/ residential-exposure-sop.html) along with policy changes for body weight assumptions. Even though a previous risk assessment identified residential handler risk estimates for use in aggregate assessment, based on current policy and that isofetamid products are intended for sale/use to/by professional applicators, residential handler exposure assessments for turf are no longer applicable to the isofetamid aggregate risk assessment. Therefore, the aggregate assessment for this action only includes a risk contribution from residential post-application incidental oral exposure for children 1 to <2 years old. There is the potential for postapplication exposure for individuals as a result of being in an environment that has been previously treated with isofetamid such as residential ornamental lawns. Since dermal hazard has not been identified for isofetamid, a quantitative assessment for dermal exposure is not necessary and the only exposure scenarios quantitatively assessed are for children 1 to <2 years old who may experience short-term incidental oral exposure to isofetamid from treated turf. Intermediate-term incidental oral post-application exposures are possible (i.e., from soil ingestion due to the persistence of isofetamid); however, the short-term incidental oral exposures are protective of the possible intermediate-term incidental oral exposures because the POD for both durations is the same. Post-application inhalation exposure is expected to be negligible for the proposed residential uses. The post-application incidental oral MOE values were calculated based on the scenario of liquid application of isofetamid to turf. Post-application risk estimates for all incidental oral scenarios are not of concern (MOEs range from 5,900 to 4,000,000). The incidental oral scenarios (i.e., hand-tomouth and object-to-mouth) should be considered inter-related and it is likely that they occur interspersed amongst E:\FR\FM\14JNR1.SGM 14JNR1 27152 Federal Register / Vol. 82, No. 113 / Wednesday, June 14, 2017 / Rules and Regulations each other across time. However, combining these scenarios would be overly-conservative because of the conservative nature of each individual assessment. Incidental oral risk estimates are highly conservative because the short- and intermediateterm incidental oral POD is based on a 90-day exposure duration which represents daily exposure for 90 days. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at https://www2.epa.gov/pesticidescience-and-assessing-pesticide-risks/ standard-operating-proceduresresidential-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 isofetamid to share a common mechanism of toxicity with any other substances, and isofetamid does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that isofetamid does not have a common mechanism of toxicity with other substances. For information regarding EPA’s efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA’s Web site at https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. mstockstill on DSK30JT082PROD with RULES 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 Food Quality Protection Act Safety Factor (FQPA SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. VerDate Sep<11>2014 16:55 Jun 13, 2017 Jkt 241001 2. Prenatal and postnatal sensitivity. There is no evidence of developmental toxicity or reproductive susceptibility, and there are no residual uncertainties concerning pre- or post-natal toxicity or exposure. 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 isofetamid is complete. ii. There is no indication that isofetamid 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 isofetamid 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. 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 isofetamid 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 isofetamid. 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. An acute aggregate risk assessment takes into account acute exposure estimates from dietary consumption of food and drinking water. No adverse effect resulting from a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, isofetamid is not expected to pose an acute risk. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded PO 00000 Frm 00048 Fmt 4700 Sfmt 4700 that chronic exposure to isofetamid from food and water will utilize 4.0% 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 residues of isofetamid 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). Isofetamid 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 isofetamid. 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 1,600 for children (1– 2 years old). Because EPA’s level of concern for isofetamid 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, isofetamid is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk is assessed based on intermediateterm 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 isofetamid. 5. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, isofetamid 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 isofetamid residues. E:\FR\FM\14JNR1.SGM 14JNR1 Federal Register / Vol. 82, No. 113 / Wednesday, June 14, 2017 / Rules and Regulations IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology liquid chromatography with tandem mass spectrometry (LC–MS/MS) method is available to enforce the tolerance expression. Multiresidue methods testing data have been submitted for isofetamid and GPTC. The data indicate that multiresidue methods are not suitable for analysis of isofetamid and GPTC, so the multiresidue methods cannot serve as enforcement methods. The multiresidue data have been forwarded to the Food and Drug Administration (FDA). 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 MRLs for isofetamid. There are no Canadian, Codex, or Mexican maximum residue limits (MRLs) for isofetamid in/on the commodities included in this petition. mstockstill on DSK30JT082PROD with RULES C. Revisions to Petitioned-For Tolerances All tolerance levels are based upon the Organization for Economic Cooperation and Development’s (OECD) tolerance calculation procedures. Thus, the tolerance levels established in this notice for isofetamid in/on bushberry, subgroup 13–07B; cherry, subgroup 12– 12A; plum, prune, dried; dried shelled pea and bean, except soybean, subgroup 6C; and succulent shelled pea and bean, subgroup 6B are lower than those requested by the petitioner. The tolerance levels established in this notice for caneberry, subgroup 13–07A and fruit, small vine climbing, except grape, subgroup 13–07E are higher than those requested by the petitioner based on the OECD calculation procedures. VerDate Sep<11>2014 16:55 Jun 13, 2017 Jkt 241001 Additionally, the Agency has determined that tolerances requested for residues in livestock commodities are not required. These tolerances fall under 40 CFR 180.6(a)(3) regarding secondary residues in livestock commodities, i.e., it is not possible to establish with certainty whether finite residues will be incurred, but there is no reasonable expectation of finite residues. The following commodity definitions have been corrected: Bushberry subgroup 13–07B; fruit, small vine climbing, except grape, subgroup 13– 07E; pea and bean, dried shelled, except soybean, subgroup 6C; and pea and bean, succulent shelled, subgroup 6B. V. Conclusion Therefore, tolerances are established for residues of isofetamid, in or on apple, wet pomace, at 2.0 parts per million (ppm); bushberry subgroup 13– 07B at 5.0 ppm; caneberry subgroup 13– 07A at 4.0 ppm; cherry subgroup 12– 12A at 4.0 ppm; fruit, pome, group 11– 10 at 0.60 ppm; fruit, small vine climbing, except grape, subgroup 13– 07E at 10.0 ppm; pea and bean, dried shelled, except soybean, subgroup 6C, at 0.040 ppm; pea and bean, succulent shelled, subgroup 6B, at 0.030 ppm; peach subgroup 12–12B at 3.0 ppm; plum, prune, dried at 1.50 ppm; plum subgroup 12–12C at 0.80 ppm; and vegetable, legume, edible podded, subgroup 6A at 1.50 ppm. Additionally, the existing time-limited tolerances are being removed for both Caneberry subgroup 13–07A at 4.0 ppm, and for Bushberry subgroup 13–07B at 5.0 ppm. 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 PO 00000 Frm 00049 Fmt 4700 Sfmt 4700 27153 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 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).

AGENCY: The Environmental Protection Agency (EPA) is promulgating technology-based pretreatment standards under the Clean Water Act to reduce discharges of mercury from dental offices into municipal sewage treatment plants known as publicly owned treatment works (POTWs). This final rule requires dental offices to use amalgam separators and two best management practices recommended by the American Dental Association (ADA). This final rule includes a provision to significantly reduce and streamline the oversight and reporting requirements in EPA’s General Pretreatment Regulations that would otherwise apply as a result of this rulemaking. EPA expects compliance with this final rule will annually reduce the discharge of mercury by 5.1 tons as well as 5.3 tons of other metals found in waste dental amalgam to POTWs. DATES: The final rule is effective on July 14, 2017. The compliance date, meaning the date that existing sources subject to the rule must comply with the standards in this rule is July 14, 2020. After the effective date of the rule, new sources subject to this rule must comply immediately with the standards in this rule. In accordance with 40 CFR part 23, this regulation shall be considered issued for purposes of judicial review at 1 p.m. Eastern time on June 28, 2017. Under section 509(b)(1) of the CWA, judicial review of this regulation can be had only by filing a petition for review in the U.S. Court of Appeals within 120 days after the regulation is considered issued for purposes of judicial review. Under section 509(b)(2), the requirements in this regulation may not be challenged later in civil or criminal proceedings brought by EPA to enforce these requirements.

II. Summary of Petitioned-For Tolerance

    In the Federal Register of February 7, 2017 (82 FR 9555) (FRL-9956-
86), 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 
6F8457) by ISK Biosciences Corporation, 7470 Auburn Rd., Suite A, 
Concord, OH 44077. The petition requested that 40 CFR 180.681 be 
amended by establishing tolerances for residues of the fungicide 
isofetamid, N-[1,1-dimethyl-2-[2-methyl-4-(1-methylethoxy)phenyl]-2-
oxoethyl]-3-methyl-2-thiophenecarboxamide, in or on caneberry subgroup 
13-07A at 3.0 parts per million (ppm); apple, wet pomace, at 2.0 ppm; 
bushberry, subgroup 13-07B at 6.0 ppm; cattle, fat at 0.01 ppm; cattle, 
meat byproducts at 0.01 ppm; cherry subgroup 12-12A at 5.0 ppm; fruit, 
pome, group 11-10 at 0.6 ppm; fruit, small vine climbing, except grape, 
subgroup 13-7E at 9.0 ppm; goat, fat at 0.01 ppm; goat, meat byproducts 
at 0.01 ppm; horse, fat at 0.01 ppm; horse, meat byproducts at 0.01 
ppm; pea and bean, dried shelled, except soybean, subgroup 6C, except 
cowpea and field pea at 0.05 ppm; pea and bean, succulent shelled, 
subgroup 6B, except cowpea at 0.04 ppm; peach subgroup 12-12B at 3.0 
ppm; plum, prune, dried at 3.5 ppm; plum subgroup 12-12C at 0.8 ppm; 
sheep, fat at 0.01 ppm; sheep, meat byproducts at 0.01 ppm; and 
vegetable, legume, edible podded, subgroup 6A at 1.5 ppm. That document 
referenced a summary of the petition prepared by ISK Biosciences 
Corporation, the registrant, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the 
notice of filing.
    Based upon review of the data supporting the petition, EPA has 
revised some of the proposed tolerances; determined that tolerances for 
residues in livestock commodities are not required; and corrected some 
of the commodity definitions. 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 isofetamid including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with isofetamid 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 toxicology database is complete for isofetamid. In 
repeated dose studies, the liver was the primary target organ in the 
rat, mouse, and dog, as indicated by increased liver weights, changes 
in the clinical chemistry values, and liver hypertrophy. A second 
target organ was the thyroid in the rat and dog, as indicated by 
changes in thyroid weights and histopathology. Adrenal weight changes 
were observed in the subchronic rat and dog studies. In the rat and 
dog, the dose levels where toxicity was observed were similar or higher 
in the chronic studies compared with the respective subchronic studies, 
showing an absence of progression of liver toxicity with time. There 
was no evidence of carcinogenicity in the rat or mouse cancer studies; 
the mutagenicity battery was negative. There are no genotoxicity, 
neurotoxicity, or immunotoxicity concerns observed in the available 
toxicity studies. Developmental toxicity was not observed in the rat or 
rabbit, and offspring effects such as decreased body weight were seen 
only in the presence of parental toxicity in the multi-generation rat 
study. Isofetamid is classified as ``Not Likely to be Carcinogenic to 
Humans'' based on the absence of increased tumor incidence in 
acceptable/guideline carcinogenicity studies in rats and mice. 
Isofetamid is not acutely toxic; it is classified as Toxicity Category 
III for acute oral and dermal exposure, and Toxicity Category IV for 
inhalation exposure. Furthermore, it is not irritating to the eye or 
skin, and it is not a dermal sensitizer.
    Specific information on the studies received and the nature of the 
adverse effects caused by isofetamid as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies are can be found at https://www.regulations.gov in document Isofetamid. Aggregate Human Health Risk

well as Livestock Commodities; in Addition to Uses on Ornamental Plants 
(including Residential Use Sites). pages 12-18 in docket ID number EPA-
HQ-OPP-2016-0263.

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

[[Page 27151]]

degree of risk. Thus, the Agency estimates risk in terms of the 
probability of an occurrence of the adverse effect expected in a 
lifetime. For more information on the general principles EPA uses in 
risk characterization and a complete description of the risk assessment 
process, see https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for isofetamid used for 
human risk assessment is discussed in Unit III.B. of the final rule 
published in the Federal Register of July 30, 2015 (80 FR 45440) (FRL-
9923-86).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to isofetamid, EPA considered exposure under the petitioned-
for tolerances as well as all existing isofetamid tolerances in 40 CFR 
180.681. EPA assessed dietary exposures from isofetamid 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 isofetamid; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. An unrefined chronic (food and drinking 
water) dietary assessment was conducted for all registered and proposed 
food uses of isofetamid using the 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). The chronic 
dietary (food and drinking water) exposure assessment for isofetamid 
incorporated existing tolerance-level residues, Agency-recommended 
tolerance-level residues for proposed tolerances, DEEM default 
processing factors, and 100 PCT (percent crop treated). Some tolerance 
levels were adjusted to include residues of the metabolite, GPTC (a 
residue of concern for risk assessment). DEEM default processing 
factors were used for dried apples, apple juice, dried pear, cherry 
juice, dried apricot, dried peach, plum, prune juice, cranberry juice, 
and grape juice. The EDWC of 110 microgram/Liter ([micro]g/L) was 
incorporated directly into the dietary assessment.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that isofetamid 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 and/or PCT information in the 
dietary assessment for isofetamid. Tolerance level residues and/or 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 isofetamid in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of isofetamid. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Pesticide Flooded Application Model and the Pesticide 
Root Zone Model Ground Water (PRZM GW) the estimated drinking water 
concentrations (EDWCs) of isofetamid for chronic exposures for non-
cancer assessments are estimated to be 110 parts per billion (ppb) for 
surface water and 43 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration value of 110 ppb was used to assess 
the contribution from 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).
    Isofetamid is currently registered for the following uses that 
could result in residential exposures: Turfgrass including golf 
courses, residential lawns, and recreational turfgrass. It is currently 
under review for registering use on ornamental plants. The proposed 
ornamental use is not intended for homeowner use and therefore a 
quantitative residential handler assessment was not conducted. 
Additionally, post-application exposures for adults and children are 
expected to be negligible. However, the existing turf use may result in 
short- and intermediate-term exposures. Residential exposure may occur 
by the dermal and incidental oral routes of exposures following the 
application of isofetamid on residential turf. However, since dermal 
hazard has not been identified for isofetamid, the only exposure 
scenario quantitatively assessed is for post-application incidental 
oral (for children 1 to <2 years old). These exposures have been 
assessed with current policies, which include the Agency's 2012 
Residential Standard Operating Procedures (https://www.epa.gov/pesticides/science/residential-exposure-sop.html) along with policy 
changes for body weight assumptions.
    Even though a previous risk assessment identified residential 
handler risk estimates for use in aggregate assessment, based on 
current policy and that isofetamid products are intended for sale/use 
to/by professional applicators, residential handler exposure 
assessments for turf are no longer applicable to the isofetamid 
aggregate risk assessment. Therefore, the aggregate assessment for this 
action only includes a risk contribution from residential post-
application incidental oral exposure for children 1 to <2 years old.
    There is the potential for post-application exposure for 
individuals as a result of being in an environment that has been 
previously treated with isofetamid such as residential ornamental 
lawns. Since dermal hazard has not been identified for isofetamid, a 
quantitative assessment for dermal exposure is not necessary and the 
only exposure scenarios quantitatively assessed are for children 1 to 
<2 years old who may experience short-term incidental oral exposure to 
isofetamid from treated turf. Intermediate-term incidental oral post-
application exposures are possible (i.e., from soil ingestion due to 
the persistence of isofetamid); however, the short-term incidental oral 
exposures are protective of the possible intermediate-term incidental 
oral exposures because the POD for both durations is the same. Post-
application inhalation exposure is expected to be negligible for the 
proposed residential uses.
    The post-application incidental oral MOE values were calculated 
based on the scenario of liquid application of isofetamid to turf. 
Post-application risk estimates for all incidental oral scenarios are 
not of concern (MOEs range from 5,900 to 4,000,000). The incidental 
oral scenarios (i.e., hand-to-mouth and object-to-mouth) should be 
considered inter-related and it is likely that they occur interspersed 
amongst

[[Page 27152]]

each other across time. However, combining these scenarios would be 
overly-conservative because of the conservative nature of each 
individual assessment. Incidental oral risk estimates are highly 
conservative because the short- and intermediate-term incidental oral 
POD is based on a 90-day exposure duration which represents daily 
exposure for 90 days. Further information regarding EPA standard 
assumptions and generic inputs for residential exposures may be found 
at https://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 isofetamid to share a common mechanism of 
toxicity with any other substances, and isofetamid does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
isofetamid does not have a common mechanism of toxicity with other 
substances. For information regarding EPA's efforts to determine which 
chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's Web site at https://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 Food Quality 
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA 
either retains the default value of 10X, or uses a different additional 
safety factor when reliable data available to EPA support the choice of 
a different factor.
    2. Prenatal and postnatal sensitivity. There is no evidence of 
developmental toxicity or reproductive susceptibility, and there are no 
residual uncertainties concerning pre- or post-natal toxicity or 
exposure.
    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 isofetamid is complete.
    ii. There is no indication that isofetamid 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 isofetamid 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.
    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 isofetamid 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 
isofetamid.

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. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
isofetamid is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
isofetamid from food and water will utilize 4.0% 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 residues of 
isofetamid 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). Isofetamid 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 isofetamid.
    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 1,600 for 
children (1-2 years old). Because EPA's level of concern for isofetamid 
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, 
isofetamid 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 
isofetamid.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, isofetamid 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 isofetamid residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology liquid chromatography with tandem 
mass spectrometry (LC-MS/MS) method is available to enforce the 
tolerance expression. Multiresidue methods testing data have been 
submitted for isofetamid and GPTC. The data indicate that multiresidue 
methods are not suitable for analysis of isofetamid and GPTC, so the 
multiresidue methods cannot serve as enforcement methods. The 
multiresidue data have been forwarded to the Food and Drug 
Administration (FDA).

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 MRLs for isofetamid. There are no 
Canadian, Codex, or Mexican maximum residue limits (MRLs) for 
isofetamid in/on the commodities included in this petition.

C. Revisions to Petitioned-For Tolerances

    All tolerance levels are based upon the Organization for Economic 
Co-operation and Development's (OECD) tolerance calculation procedures. 
Thus, the tolerance levels established in this notice for isofetamid 
in/on bushberry, subgroup 13-07B; cherry, subgroup 12-12A; plum, prune, 
dried; dried shelled pea and bean, except soybean, subgroup 6C; and 
succulent shelled pea and bean, subgroup 6B are lower than those 
requested by the petitioner. The tolerance levels established in this 
notice for caneberry, subgroup 13-07A and fruit, small vine climbing, 
except grape, subgroup 13-07E are higher than those requested by the 
petitioner based on the OECD calculation procedures.
    Additionally, the Agency has determined that tolerances requested 
for residues in livestock commodities are not required. These 
tolerances fall under 40 CFR 180.6(a)(3) regarding secondary residues 
in livestock commodities, i.e., it is not possible to establish with 
certainty whether finite residues will be incurred, but there is no 
reasonable expectation of finite residues.
    The following commodity definitions have been corrected: Bushberry 
subgroup 13-07B; fruit, small vine climbing, except grape, subgroup 13-
07E; pea and bean, dried shelled, except soybean, subgroup 6C; and pea 
and bean, succulent shelled, subgroup 6B.

V. Conclusion

    Therefore, tolerances are established for residues of isofetamid, 
in or on apple, wet pomace, at 2.0 parts per million (ppm); bushberry 
subgroup 13-07B at 5.0 ppm; caneberry subgroup 13-07A at 4.0 ppm; 
cherry subgroup 12-12A at 4.0 ppm; fruit, pome, group 11-10 at 0.60 
ppm; fruit, small vine climbing, except grape, subgroup 13-07E at 10.0 
ppm; pea and bean, dried shelled, except soybean, subgroup 6C, at 0.040 
ppm; pea and bean, succulent shelled, subgroup 6B, at 0.030 ppm; peach 
subgroup 12-12B at 3.0 ppm; plum, prune, dried at 1.50 ppm; plum 
subgroup 12-12C at 0.80 ppm; and vegetable, legume, edible podded, 
subgroup 6A at 1.50 ppm. Additionally, the existing time-limited 
tolerances are being removed for both Caneberry subgroup 13-07A at 4.0 
ppm, and for Bushberry subgroup 13-07B at 5.0 ppm.

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 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 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).
