This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerances in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply. This action directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 2000) do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note). VII. Congressional Review Act Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal VerDate Sep<11>2014 16:33 Jun 13, 2016 Jkt 238001 Register.

Summary of Petitioned-For Tolerance In the Federal Register of February 11, 2015 (80 FR 7559) (FRL–9921–94), 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 4E8312) by IR–4, IR–4 Project Headquarters, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201 W, Princeton, NJ 08540. The petition requested that 40 CFR 180.446 be amended by establishing tolerances for residues of the acaricide clofentezine in or on avocado at 0.3 parts per million (ppm); papaya at 0.3 ppm; fruit, pome, group 11–10 at 0.5 ppm; cherry, subgroup 12–12A at 1.0 ppm; peach, subgroup 12–12B at 1.0 ppm; and fruit, small, vine climbing, except fuzzy kiwifruit, subgroup 13–07F at 1.0 ppm. Upon the approval of the aforementioned tolerances, IR–4 proposed that the existing tolerances for apple at 0.5 ppm; pear at 0.5 ppm; cherry at 1.0 ppm; nectarine at 1.0 ppm; peach at 1.0 ppm; and grape at 1.0 ppm be removed as unnecessary. That document referenced a summary of the petition prepared by Makhteshim Agan of North America, the registrant, which is available in the docket, https:// www.regulations.gov. One comment was received in response to the notice of PO 00000 Frm 00037 Fmt 4700 Sfmt 4700 38605 filing, however it related to a different chemical. 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 clofentezine including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with clofentezine 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 studies indicate the liver is the primary target organ for clofentezine with secondary effects on the thyroid. Body weight and body weight gain were decreased whereas liver weights were increased and hepatocellular enlargement was reported along with other observations (increases in plasma cholesterol and triglyceride levels). The induction of the liver enzyme, uridine diphosphate glucuronyltransferase (UDPGT) and the subsequent increase in the metabolism and the excretion of the thyroid E:\FR\FM\14JNR1.SGM 14JNR1 38606 Federal Register / Vol. 81, No. 114 / Tuesday, June 14, 2016 / Rules and Regulations hormone T4 reduced the availability of T4 required for the general metabolism and the maintenance of homeostasis. The decreased levels of plasma T4 resulted in the stimulation of the thyroid by the pituitary gland to raise the plasma T4 levels. Thyroid changes in the form of colloid depletion, thyroid follicular cell hypertrophy and hyperplasia were observed as a means to regain the homeostasis. Two pre-natal developmental toxicity studies are available, one in the rat and one in the rabbit. No evidence (quantitative or qualitative) of increased susceptibility was seen in either study (developmental NOAELs were set at or above the limit dose for both studies). There was no evidence (quantitative or qualitative) of increased susceptibility seen following pre-and/or post-natal exposure in rats for 2-generations in the reproduction study (NOAEL set at the highest dose tested). Clofentezine does cause thyroid tumors in male rats after long-term high exposure resulting in progressive effects on the thyroid that leads to hyperplasia and eventual tumor formation. No mechanism or mode of action has been submitted to the Agency at this time for clofentezine. As a result, clofentezine has been classified as a possible human carcinogen based on male rat thyroid follicular cell adenoma and/or carcinoma combined tumor rates. The Q1* value for use in clofentezine risk assessment using the 3⁄4 inter species scaling factor is 3.76 × 10¥2 (mg/kg/ day)¥1. Clofentezine is not considered to be a mutagen. Specific information on the studies received and the nature of the adverse effects caused by clofentezine as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies can be found at https:// www.regulations.gov in the document titled ‘‘Clofentezine.’’ Human-Health Risk Assessment to Support a Section 3 Registration Request to Add New Uses on Avocado and Papaya, and New Uses for Pome Fruit Group 11–10, Cherry sub-group 12–12A, Peach sub-group 12– 12B, and Small Fruit Vine Climbing except Fuzzy Kiwifruit Subgroup 13– 07F based on Existing Tolerances on Representative Commodities’’ on page 38 in docket ID number EPA–HQ–OPP– 2014–0749. 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 https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides. A summary of the toxicological endpoints for clofentezine used for human risk assessment is shown in Table 1 of this Unit.

Dietary exposure from food and feed uses. In evaluating dietary exposure to clofentezine, EPA considered exposure under the petitioned-for tolerances as well as all existing clofentezine tolerances in 40 CFR 180.446. EPA assessed dietary exposures from clofentezine in food as follows: VerDate Sep<11>2014 16:33 Jun 13, 2016 Jkt 238001 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 clofentezine; therefore, a quantitative acute dietary exposure assessment is unnecessary. PO 00000 Frm 00038 Fmt 4700 Sfmt 4700 ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the 2003–2008 food consumption data from the U.S. Department of Agriculture’s (USDA) National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in food, a partially refined chronic dietary exposure and risk assessment was performed that directly E:\FR\FM\14JNR1.SGM 14JNR1 sradovich on DSK3TPTVN1PROD with RULES Federal Register / Vol. 81, No. 114 / Tuesday, June 14, 2016 / Rules and Regulations incorporated average field trial residues and used percent crop treated information. iii. Cancer. EPA determines whether quantitative cancer exposure and risk assessments are appropriate for a fooduse pesticide based on the weight of the evidence from cancer studies and other relevant data. If quantitative cancer risk assessment is appropriate, cancer risk may be quantified using a linear or nonlinear approach. If sufficient information on the carcinogenic mode of action is available, a threshold or nonlinear approach is used and a cancer RfD is calculated based on an earlier non cancer key event. If carcinogenic mode of action data are not available, or if the mode of action data determines a mutagenic mode of action, a default linear cancer slope factor approach is utilized. Based on the data summarized in Unit III.A., EPA has concluded that clofentezine should be classified as possible human carcinogen and a linear approach has been used to quantify cancer risk. Cancer risk was quantified using the same estimates as discussed in Unit III.C.1.ii. iv. Anticipated residue and percent crop treated (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. Section 408(b)(2)(F) of FFDCA states that the Agency may use data on the actual percent of food treated for assessing chronic dietary risk only if: • Condition a: The data used are reliable and provide a valid basis to show what percentage of the food derived from such crop is likely to contain the pesticide residue. • Condition b: The exposure estimate does not underestimate exposure for any significant subpopulation group. • Condition c: Data are available on pesticide use and food consumption in a particular area, the exposure estimate does not understate exposure for the population in such area. In addition, the Agency must provide for periodic evaluation of any estimates used. To VerDate Sep<11>2014 16:33 Jun 13, 2016 Jkt 238001 provide for the periodic evaluation of the estimate of PCT as required by FFDCA section 408(b)(2)(F), EPA may require registrants to submit data on PCT. Average percent crop treated estimates were used in the chronic and cancer dietary risk assessments for the following crops that are currently registered for clofentezine: Almonds: 5%; apples: 2.5%; apricots: 2.5%; cherries: 5%; grapes: 1%; nectarines: 5%; peaches: 5%; pears: 5%; and walnuts: 5%. In most cases, EPA uses available data from United States Department of Agriculture/National Agricultural Statistics Service (USDA/NASS), proprietary market surveys, and the National Pesticide Use Database for the chemical/crop combination for the most recent 6–7 years. EPA uses an average PCT for chronic dietary risk analysis. The average PCT figure for each existing use is derived by combining available public and private market survey data for that use, averaging across all observations, and rounding to the nearest 5%, except for those situations in which the average PCT is less than one. In those cases, 1% is used as the average PCT and 2.5% is used as the maximum PCT. EPA uses a maximum PCT for acute dietary risk analysis. The maximum PCT figure is the highest observed maximum value reported within the recent 6 years of available public and private market survey data for the existing use and rounded up to the nearest multiple of 5%. The Agency believes that the three conditions discussed in Unit III.C.1.iv. have been met. With respect to Condition a, PCT estimates are derived from Federal and private market survey data, which are reliable and have a valid basis. The Agency is reasonably certain that the percentage of the food treated is not likely to be an underestimation. As to Conditions b and c, regional consumption information and consumption information for significant subpopulations is taken into account through EPA’s computer-based model for evaluating the exposure of significant subpopulations including several regional groups. Use of this consumption information in EPA’s risk assessment process ensures that EPA’s exposure estimate does not understate exposure for any significant subpopulation group and allows the Agency to be reasonably certain that no regional population is exposed to residue levels higher than those estimated by the Agency. Other than the data available through national food consumption surveys, EPA does not have available reliable information on PO 00000 Frm 00039 Fmt 4700 Sfmt 4700 38607 the regional consumption of food to which clofentezine may be applied in a particular area. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for clofentezine in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of clofentezine. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at https://www2.epa.gov/ pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide. Based on the First Index Reservoir Screening Tool (FIRST) and Screening Concentration in Ground Water (SCI– GROW) models, the estimated drinking water concentrations (EDWCs) of clofentezine for chronic exposures for non-cancer and cancer assessments are estimated to be 0.062 parts per billion (ppb) for surface water and 0.041 ppb for ground water. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic and cancer dietary risk assessment, the water concentration of value 0.062 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 nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Clofentezine is not registered for any specific use patterns that would result in residential exposure. 4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider ‘‘available information’’ concerning the cumulative effects of a particular pesticide’s residues and ‘‘other substances that have a common mechanism of toxicity.’’ EPA has not found clofentezine to share a common mechanism of toxicity with any other substances, and clofentezine does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that clofentezine 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 E:\FR\FM\14JNR1.SGM 14JNR1 38608 Federal Register / Vol. 81, No. 114 / Tuesday, June 14, 2016 / Rules and Regulations sradovich on DSK3TPTVN1PROD with RULES the cumulative effects of such chemicals, see EPA’s Web site at https:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. of clofentezine were incorporated directly into the chronic and cancer assessments. These assessments will not underestimate the exposure and risks posed by clofentezine. 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. Two pre-natal developmental toxicity studies were available, one in the rat and one in the rabbit. No evidence (quantitative or qualitative) of increased susceptibility was seen in either study (developmental NOAELs were set at or above the limit dose for both studies). There was no evidence (quantitative or qualitative) of increased susceptibility seen following pre-and/or post-natal exposure in rats for 2-generations in the reproduction study (NOAEL set at the highest dose tested). 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 clofentezine is complete. ii. There is no indication that clofentezine 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 clofentezine 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 chronic and cancer analyses incorporated anticipated residues (average residues from available field trial data) for all registered and proposed commodities and the latest PCT data available. The highest estimated drinking water concentrations 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, clofentezine 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 clofentezine from food and water will utilize <1% of the cPAD for all population groups. There are no residential uses for clofentezine. 3. Short- and intermediate-term risk. Short- and intermediate-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). A short- and intermediate-term adverse effect was identified; however, clofentezine is not registered for any use patterns that would result in short- or intermediate-term residential exposure. Short- and intermediate-term risk is assessed based on short- and intermediate-term residential exposure plus chronic dietary exposure. Because there is no short- or 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 short- or intermediate-term risk), no further assessment of short- or intermediateterm risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short- and intermediate-term risk for clofentezine. 4. Aggregate cancer risk for U.S. population. Using the exposure assumptions described in this unit for VerDate Sep<11>2014 16:33 Jun 13, 2016 Jkt 238001 PO 00000 Frm 00040 Fmt 4700 Sfmt 4700 cancer exposure, EPA has concluded that by applying the Q1* of 3.76 × 10¥2 mg/kg/day to the exposure value results in a cancer risk estimate of 3.8 × 10¥7 to the general U.S. population. EPA generally considers cancer risks (expressed as the probability of an increased cancer case) in the range of 1 in 1 million (or 1 × 10¥6) or less to be negligible. 5. 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 clofentezine residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (high performance liquid chromatography (HPLC)) 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: 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. There are no Codex MRLs for residues on avocado and papaya. The U.S. pome fruit tolerance of 0.5 ppm is harmonized with the Codex MRL. The U.S. tolerance is 1.0 ppm in/on stone fruit (12–12A and 12–12B). The Codex MRL for stone fruit is 0.5 ppm. The clofentezine residues in/on representative stone fruit crops, cherry and peach, from the submitted U.S. field trial data are greater than 0.5 ppm and E:\FR\FM\14JNR1.SGM 14JNR1 38609 Federal Register / Vol. 81, No. 114 / Tuesday, June 14, 2016 / Rules and Regulations setting the tolerances for 12–12A and 12–12B at 0.5 ppm to harmonize with Codex could result a tolerance exceedance for U.S. growers. Therefore, the U.S. tolerance cannot be harmonized with Codex MRL for stone fruit at this time. The U.S. tolerance of 1.0 ppm for the crop subgroup fruit, small, vine climbing, except fuzzy kiwifruit, 13–07F does not harmonize with the Codex MRL of 2.0 ppm. The petitioner requested a 13–07F subgroup tolerance at 1.0 ppm, which would maintain the existing tolerance on grapes at 1.0 ppm consistent with the MRL at 1.0 ppm maintained by several countries including Japan and Korea. EPA is not harmonizing with Codex in order to maintain MRL harmony with several other countries to avoid potential export issues. sradovich on DSK3TPTVN1PROD with RULES V. Conclusion Therefore, tolerances are established for residues of clofentezine in or on avocado at 0.30 ppm; papaya at 0.30 ppm; fruit, pome, group 11–10 at 0.50 ppm; cherry, subgroup 12–12A at 1.0 ppm; peach, subgroup 12–12B at 1.0 ppm; and fruit, small, vine climbing, except fuzzy kiwifruit, subgroup 13–07F at 1.0 ppm. In addition, the existing tolerances for apple at 0.5 ppm; pear at 0.5 ppm; cherry at 1.0 ppm; nectarine at 1.0 ppm; peach at 1.0 ppm; and grape at 1.0 ppm are removed as unnecessary. 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 VerDate Sep<11>2014 16:33 Jun 13, 2016 Jkt 238001 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 PO 00000 Frm 00041 Fmt 4700 Sfmt 9990 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).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of February 11, 2015 (80 FR 7559) (FRL-
9921-94), 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 
4E8312) by IR-4, IR-4 Project Headquarters, Rutgers, The State 
University of New Jersey, 500 College Road East, Suite 201 W, 
Princeton, NJ 08540. The petition requested that 40 CFR 180.446 be 
amended by establishing tolerances for residues of the acaricide 
clofentezine in or on avocado at 0.3 parts per million (ppm); papaya at 
0.3 ppm; fruit, pome, group 11-10 at 0.5 ppm; cherry, subgroup 12-12A 
at 1.0 ppm; peach, subgroup 12-12B at 1.0 ppm; and fruit, small, vine 
climbing, except fuzzy kiwifruit, subgroup 13-07F at 1.0 ppm. Upon the 
approval of the aforementioned tolerances, IR-4 proposed that the 
existing tolerances for apple at 0.5 ppm; pear at 0.5 ppm; cherry at 
1.0 ppm; nectarine at 1.0 ppm; peach at 1.0 ppm; and grape at 1.0 ppm 
be removed as unnecessary. That document referenced a summary of the 
petition prepared by Makhteshim Agan of North America, the registrant, 
which is available in the docket, https://www.regulations.gov. One 
comment was received in response to the notice of filing, however it 
related to a different chemical.

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 clofentezine including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with clofentezine 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 studies indicate the liver is the primary 
target organ for clofentezine with secondary effects on the thyroid. 
Body weight and body weight gain were decreased whereas liver weights 
were increased and hepatocellular enlargement was reported along with 
other observations (increases in plasma cholesterol and triglyceride 
levels). The induction of the liver enzyme, uridine diphosphate 
glucuronyltransferase (UDPGT) and the subsequent increase in the 
metabolism and the excretion of the thyroid

[[Page 38606]]

hormone T4 reduced the availability of T4 required for the general 
metabolism and the maintenance of homeostasis. The decreased levels of 
plasma T4 resulted in the stimulation of the thyroid by the pituitary 
gland to raise the plasma T4 levels. Thyroid changes in the form of 
colloid depletion, thyroid follicular cell hypertrophy and hyperplasia 
were observed as a means to regain the homeostasis.
    Two pre-natal developmental toxicity studies are available, one in 
the rat and one in the rabbit. No evidence (quantitative or 
qualitative) of increased susceptibility was seen in either study 
(developmental NOAELs were set at or above the limit dose for both 
studies). There was no evidence (quantitative or qualitative) of 
increased susceptibility seen following pre-and/or post-natal exposure 
in rats for 2-generations in the reproduction study (NOAEL set at the 
highest dose tested).
    Clofentezine does cause thyroid tumors in male rats after long-term 
high exposure resulting in progressive effects on the thyroid that 
leads to hyperplasia and eventual tumor formation. No mechanism or mode 
of action has been submitted to the Agency at this time for 
clofentezine. As a result, clofentezine has been classified as a 
possible human carcinogen based on male rat thyroid follicular cell 
adenoma and/or carcinoma combined tumor rates. The Q1* value 
for use in clofentezine risk assessment using the \3/4\ inter species 
scaling factor is 3.76 x 10-\2\ (mg/kg/day)-\1\. 
Clofentezine is not considered to be a mutagen.
    Specific information on the studies received and the nature of the 
adverse effects caused by clofentezine as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in the document titled ``Clofentezine.'' Human-

Vine Climbing except Fuzzy Kiwifruit Subgroup 13-07F based on Existing 
Tolerances on Representative Commodities'' on page 38 in docket ID 
number EPA-HQ-OPP-2014-0749.

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 https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for clofentezine used for 
human risk assessment is shown in Table 1 of this Unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to clofentezine, EPA considered exposure under the petitioned-
for tolerances as well as all existing clofentezine tolerances in 40 
CFR 180.446. EPA assessed dietary exposures from clofentezine 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 clofentezine; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the 2003-2008 food consumption data from the U.S. 
Department of Agriculture's (USDA) National Health and Nutrition 
Examination Survey, What We Eat in America, (NHANES/WWEIA). As to 
residue levels in food, a partially refined chronic dietary exposure 
and risk assessment was performed that directly

[[Page 38607]]

incorporated average field trial residues and used percent crop treated 
information.
    iii. Cancer. EPA determines whether quantitative cancer exposure 
and risk assessments are appropriate for a food-use pesticide based on 
the weight of the evidence from cancer studies and other relevant data. 
If quantitative cancer risk assessment is appropriate, cancer risk may 
be quantified using a linear or nonlinear approach. If sufficient 
information on the carcinogenic mode of action is available, a 
threshold or nonlinear approach is used and a cancer RfD is calculated 
based on an earlier non cancer key event. If carcinogenic mode of 
action data are not available, or if the mode of action data determines 
a mutagenic mode of action, a default linear cancer slope factor 
approach is utilized. Based on the data summarized in Unit III.A., EPA 
has concluded that clofentezine should be classified as possible human 
carcinogen and a linear approach has been used to quantify cancer risk. 
Cancer risk was quantified using the same estimates as discussed in 
Unit III.C.1.ii.
    iv. Anticipated residue and percent crop treated (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.
    Section 408(b)(2)(F) of FFDCA states that the Agency may use data 
on the actual percent of food treated for assessing chronic dietary 
risk only if:
     Condition a: The data used are reliable and provide a 
valid basis to show what percentage of the food derived from such crop 
is likely to contain the pesticide residue.
     Condition b: The exposure estimate does not underestimate 
exposure for any significant subpopulation group.
     Condition c: Data are available on pesticide use and food 
consumption in a particular area, the exposure estimate does not 
understate exposure for the population in such area. In addition, the 
Agency must provide for periodic evaluation of any estimates used. To 
provide for the periodic evaluation of the estimate of PCT as required 
by FFDCA section 408(b)(2)(F), EPA may require registrants to submit 
data on PCT.
    Average percent crop treated estimates were used in the chronic and 
cancer dietary risk assessments for the following crops that are 
currently registered for clofentezine: Almonds: 5%; apples: 2.5%; 
apricots: 2.5%; cherries: 5%; grapes: 1%; nectarines: 5%; peaches: 5%; 
pears: 5%; and walnuts: 5%.
    In most cases, EPA uses available data from United States 
Department of Agriculture/National Agricultural Statistics Service 
(USDA/NASS), proprietary market surveys, and the National Pesticide Use 
Database for the chemical/crop combination for the most recent 6-7 
years. EPA uses an average PCT for chronic dietary risk analysis. The 
average PCT figure for each existing use is derived by combining 
available public and private market survey data for that use, averaging 
across all observations, and rounding to the nearest 5%, except for 
those situations in which the average PCT is less than one. In those 
cases, 1% is used as the average PCT and 2.5% is used as the maximum 
PCT. EPA uses a maximum PCT for acute dietary risk analysis. The 
maximum PCT figure is the highest observed maximum value reported 
within the recent 6 years of available public and private market survey 
data for the existing use and rounded up to the nearest multiple of 5%.
    The Agency believes that the three conditions discussed in Unit 
III.C.1.iv. have been met. With respect to Condition a, PCT estimates 
are derived from Federal and private market survey data, which are 
reliable and have a valid basis. The Agency is reasonably certain that 
the percentage of the food treated is not likely to be an 
underestimation. As to Conditions b and c, regional consumption 
information and consumption information for significant subpopulations 
is taken into account through EPA's computer-based model for evaluating 
the exposure of significant subpopulations including several regional 
groups. Use of this consumption information in EPA's risk assessment 
process ensures that EPA's exposure estimate does not understate 
exposure for any significant subpopulation group and allows the Agency 
to be reasonably certain that no regional population is exposed to 
residue levels higher than those estimated by the Agency. Other than 
the data available through national food consumption surveys, EPA does 
not have available reliable information on the regional consumption of 
food to which clofentezine may be applied in a particular area.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for clofentezine in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of clofentezine. 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 First Index Reservoir Screening Tool (FIRST) and 
Screening Concentration in Ground Water (SCI-GROW) models, the 
estimated drinking water concentrations (EDWCs) of clofentezine for 
chronic exposures for non-cancer and cancer assessments are estimated 
to be 0.062 parts per billion (ppb) for surface water and 0.041 ppb for 
ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic and cancer dietary 
risk assessment, the water concentration of value 0.062 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).
    Clofentezine is not registered for any specific use patterns that 
would result in residential exposure.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    EPA has not found clofentezine to share a common mechanism of 
toxicity with any other substances, and clofentezine does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
clofentezine 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

[[Page 38608]]

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 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. Two pre-natal developmental 
toxicity studies were available, one in the rat and one in the rabbit. 
No evidence (quantitative or qualitative) of increased susceptibility 
was seen in either study (developmental NOAELs were set at or above the 
limit dose for both studies). There was no evidence (quantitative or 
qualitative) of increased susceptibility seen following pre-and/or 
post-natal exposure in rats for 2-generations in the reproduction study 
(NOAEL set at the highest dose tested).
    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 clofentezine is complete.
    ii. There is no indication that clofentezine 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 clofentezine 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 chronic and cancer analyses incorporated anticipated 
residues (average residues from available field trial data) for all 
registered and proposed commodities and the latest PCT data available. 
The highest estimated drinking water concentrations of clofentezine 
were incorporated directly into the chronic and cancer assessments. 
These assessments will not underestimate the exposure and risks posed 
by clofentezine.

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, 
clofentezine 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 
clofentezine from food and water will utilize <1% of the cPAD for all 
population groups. There are no residential uses for clofentezine.
    3. Short- and intermediate-term risk. Short- and intermediate-term 
aggregate exposure takes into account short-term residential exposure 
plus chronic exposure to food and water (considered to be a background 
exposure level).
    A short- and intermediate-term adverse effect was identified; 
however, clofentezine is not registered for any use patterns that would 
result in short- or intermediate-term residential exposure. Short- and 
intermediate-term risk is assessed based on short- and intermediate-
term residential exposure plus chronic dietary exposure. Because there 
is no short- or 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 short- or intermediate-term risk), no further assessment of 
short- or intermediate-term risk is necessary, and EPA relies on the 
chronic dietary risk assessment for evaluating short- and intermediate-
term risk for clofentezine.
    4. Aggregate cancer risk for U.S. population. Using the exposure 
assumptions described in this unit for cancer exposure, EPA has 
concluded that by applying the Q1* of 3.76 x 
10-\2\ mg/kg/day to the exposure value results in a cancer 
risk estimate of 3.8 x 10-\7\ to the general U.S. 
population. EPA generally considers cancer risks (expressed as the 
probability of an increased cancer case) in the range of 1 in 1 million 
(or 1 x 10-\6\) or less to be negligible.
    5. 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 clofentezine residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (high performance liquid 
chromatography (HPLC)) 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: 
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.
    There are no Codex MRLs for residues on avocado and papaya.
    The U.S. pome fruit tolerance of 0.5 ppm is harmonized with the 
Codex MRL.
    The U.S. tolerance is 1.0 ppm in/on stone fruit (12-12A and 12-
12B). The Codex MRL for stone fruit is 0.5 ppm. The clofentezine 
residues in/on representative stone fruit crops, cherry and peach, from 
the submitted U.S. field trial data are greater than 0.5 ppm and

[[Page 38609]]

setting the tolerances for 12-12A and 12-12B at 0.5 ppm to harmonize 
with Codex could result a tolerance exceedance for U.S. growers. 
Therefore, the U.S. tolerance cannot be harmonized with Codex MRL for 
stone fruit at this time.
    The U.S. tolerance of 1.0 ppm for the crop subgroup fruit, small, 
vine climbing, except fuzzy kiwifruit, 13-07F does not harmonize with 
the Codex MRL of 2.0 ppm. The petitioner requested a 13-07F subgroup 
tolerance at 1.0 ppm, which would maintain the existing tolerance on 
grapes at 1.0 ppm consistent with the MRL at 1.0 ppm maintained by 
several countries including Japan and Korea. EPA is not harmonizing 
with Codex in order to maintain MRL harmony with several other 
countries to avoid potential export issues.

V. Conclusion

    Therefore, tolerances are established for residues of clofentezine 
in or on avocado at 0.30 ppm; papaya at 0.30 ppm; fruit, pome, group 
11-10 at 0.50 ppm; cherry, subgroup 12-12A at 1.0 ppm; peach, subgroup 
12-12B at 1.0 ppm; and fruit, small, vine climbing, except fuzzy 
kiwifruit, subgroup 13-07F at 1.0 ppm. In addition, the existing 
tolerances for apple at 0.5 ppm; pear at 0.5 ppm; cherry at 1.0 ppm; 
nectarine at 1.0 ppm; peach at 1.0 ppm; and grape at 1.0 ppm are 
removed as unnecessary.

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).
