Summary of Petitioned-For Tolerance In the Federal Register of July 24, 2018 (83 FR 34968) (FRL–9980–31), 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 8E8660) by The Interregional Research Project Number 4 (IR–4), Rutgers, The State University of New Jersey, 500 College Road East, Suite 201W, Princeton, NJ 08540. The petition requested that 40 CFR 180.446 be amended by establishing tolerances for residues of the insecticide VerDate Sep<11>2014 16:21 May 28, 2019 Jkt 247001 clofentezine, 3,6-bis(2-chlorphenyl)1,2,4,5-tetrazine, in or on guava at 1 part per million (ppm). That document referenced a summary of the petition prepared by Makhteshim Agan of North America (ADAMA), the registrant, which is available in the docket, https:// www.regulations.gov. One comment was received on the notice of filing. EPA’s response to the comment is discussed in Unit IV.C. Based upon review of the data supporting the petition, EPA is establishing a tolerance level for residues in or on guava at 3 ppm rather than 1 ppm as requested. The reason for this change is 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 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 PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 24723 infants and children. The primary target organ is the liver with secondary effects on the thyroid. There is no concern for increased quantitative or qualitative susceptibility of the young following in utero (rats and rabbits) and pre-and post-natal exposure (rats) to clofentezine. 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 clofentezine using the 3⁄4 interspecies scaling factor is 3.76 × 10¥2 (mg/kg/day)¥1. Clofentezine is not considered a mutagen. Further detail on the toxicological profile for clofentezine is discussed in Unit II.A. of the final rule published in the Federal Register of June 14, 2016 (81 FR 38605) (FRL–9942–23). 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 document ‘‘Clofentezine. Human-Health Risk Assessment to Support a Section 3 New Use on Guava’’ at page 14 in docket ID number EPA–HQ–OPP–2018–0275. 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:// E:\FR\FM\29MYR1.SGM 29MYR1 24724 Federal Register / Vol. 84, No. 103 / Wednesday, May 29, 2019 / Rules and Regulations khammond on DSKBBV9HB2PROD with RULES www.epa.gov/pesticide-science-andassessing-pesticide-risks. A summary of the toxicological endpoints for clofentezine used for human risk assessment is discussed in Unit II.B of the final rule published in the Federal Register of June 14, 2016 (81 FR 38606) (FRL–9942–23). 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 food consumption data from the United States Department of Agriculture’s (USDA’s) 2003–2008 National Health and Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA). As to residue levels in food, EPA used anticipated residues (average residues from available field trial data) for all registered and proposed commodities as well as empirical and updated 2018 default processing factors. Where data were available, the Agency used percent crop treated estimates; otherwise, EPA assumed 100 percent crop treated. iii. Cancer. Based on the data cited in Unit III.A., EPA has concluded that clofentezine should be classified as ‘‘Likely to be Carcinogenic to Humans’’ 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., Chronic exposure. 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 VerDate Sep<11>2014 16:21 May 28, 2019 Jkt 247001 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, and 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. The Agency estimated the average PCT for existing uses as follows: 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 PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 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://www.epa.gov/ pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide. Based on the First Index Reservoir Screening Tool (FIRST) and Pesticide Root Zone Model Ground Water (PRZM–GW) models, the estimated drinking water concentrations (EDWCs) of clofentezine acute exposures are estimated to be 7.59 parts per billion (ppb) for surface water and less than 0.05 ppb for ground water. For chronic exposures for non-cancer assessments, the EDWCs are estimated to be 0.062 ppb for surface water and less than 0.05 ppb for ground water. For chronic exposures for cancer assessments, the EDWC is estimated to be 0.025 ppb for surface. Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic dietary risk assessment, the water concentration value of 0.062 ppb was used to assess the contribution to drinking water. For cancer dietary risk assessment, the water concentration value of 0.025 ppb was used to assess the contribution to drinking water. E:\FR\FM\29MYR1.SGM 29MYR1 Federal Register / Vol. 84, No. 103 / Wednesday, May 29, 2019 / Rules and Regulations khammond on DSKBBV9HB2PROD with RULES 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 the cumulative effects of such chemicals, see EPA’s website at https:// www.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. D. Safety Factor for Infants and Children 1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. 2. Prenatal and postnatal sensitivity. There is no concern for increased quantitative or qualitative susceptibility of the young following in utero (rats and rabbits) and pre-and post-natal exposure (rats) to clofentezine. 3. Conclusion. EPA has determined that reliable data show the safety of infants and children would be VerDate Sep<11>2014 16:21 May 28, 2019 Jkt 247001 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. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to clofentezine in drinking water. 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 less than 1% of the cPAD for the general U.S. population and all population subgroups. There are no residential uses for clofentezine. 3. Short- and Intermediate-term risk. Short- and intermediate-term aggregate exposure takes into account short- and intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Short- and intermediate-term adverse effects were PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 24725 identified; however, clofentezine is not registered for any use patterns that would result in short- or intermediateterm 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 × 10¥2 (mg/kg/day)¥1 to the exposure value results in a cancer risk estimate of 3.9 × 10¥7 for adults. 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 limit of quantitation (LOQ) and limit of detection (LOD) were determined to be 0.01 ppm and 0.003 ppm, respectively. 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 E:\FR\FM\29MYR1.SGM 29MYR1 24726 Federal Register / Vol. 84, No. 103 / Wednesday, May 29, 2019 / Rules and Regulations 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 an MRL for clofentezine on guava. C. Response to Comments One comment was received on the Notice of Filing expressing concern about pollution in cities due to human waste. The comment did not raise any issue related to the Agency’s safety determination for clofentezine tolerances. The receipt of this comment is acknowledged; however, this comment is not relevant to this action. D. Revisions to Petitioned-For Tolerances The Agency is establishing a tolerance for residues of clofentezine in or on guava at 3 ppm, rather than 1 ppm as requested. The storage stability data indicated a low average concurrent recovery of residues in guava. To account for the low storage stability recoveries, the Agency applied a factor of 3X to the average field trial values, resulting in a calculation of higher residues on guava and a need for a higher tolerance level. khammond on DSKBBV9HB2PROD with RULES V. Conclusion Therefore, a tolerance is established for residues of clofentezine, 3,6-bis(2chlorphenyl)-1,2,4,5-tetrazine, in or on guava at 3 ppm. VI. Statutory and Executive Order Reviews This action establishes a tolerance under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997), nor is this action VerDate Sep<11>2014 16:21 May 28, 2019 Jkt 247001 considered a regulatory action under Executive Order 13771, entitled ‘‘Reducing Regulations and Controlling Regulatory Costs’’ (82 FR 9339, February 3, 2017). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply. This action directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal 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.).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 24, 2018 (83 FR 34968) (FRL-9980-
31), 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 
8E8660) by The Interregional Research Project Number 4 (IR-4), Rutgers, 
The State University of New Jersey, 500 College Road East, Suite 201W, 
Princeton, NJ 08540. The petition requested that 40 CFR 180.446 be 
amended by establishing tolerances for residues of the insecticide 
clofentezine, 3,6-bis(2-chlorphenyl)-1,2,4,5-tetrazine, in or on guava 
at 1 part per million (ppm). That document referenced a summary of the 
petition prepared by Makhteshim Agan of North America (ADAMA), the 
registrant, which is available in the docket, https://www.regulations.gov. One comment was received on the notice of filing. 
EPA's response to the comment is discussed in Unit IV.C.
    Based upon review of the data supporting the petition, EPA is 
establishing a tolerance level for residues in or on guava at 3 ppm 
rather than 1 ppm as requested. The reason for this change is 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 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. The primary target organ is the liver with secondary effects 
on the thyroid. There is no concern for increased quantitative or 
qualitative susceptibility of the young following in utero (rats and 
rabbits) and pre-and post-natal exposure (rats) to clofentezine. 
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 clofentezine using the \3/4\ 
interspecies scaling factor is 3.76 x 10-\2\ (mg/kg/
day)-\1\. Clofentezine is not considered a mutagen.
    Further detail on the toxicological profile for clofentezine is 
discussed in Unit II.A. of the final rule published in the Federal 
Register of June 14, 2016 (81 FR 38605) (FRL-9942-23).
    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 document ``Clofentezine. Human-Health Risk 
Assessment to Support a Section 3 New Use on Guava'' at page 14 in 
docket ID number EPA-HQ-OPP-2018-0275.

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://

[[Page 24724]]

www.epa.gov/pesticide-science-and-assessing-pesticide-risks.
    A summary of the toxicological endpoints for clofentezine used for 
human risk assessment is discussed in Unit II.B of the final rule 
published in the Federal Register of June 14, 2016 (81 FR 38606) (FRL-
9942-23).

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 food consumption data from the United States 
Department of Agriculture's (USDA's) 2003-2008 National Health and 
Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA). As 
to residue levels in food, EPA used anticipated residues (average 
residues from available field trial data) for all registered and 
proposed commodities as well as empirical and updated 2018 default 
processing factors. Where data were available, the Agency used percent 
crop treated estimates; otherwise, EPA assumed 100 percent crop 
treated.
    iii. Cancer. Based on the data cited in Unit III.A., EPA has 
concluded that clofentezine should be classified as ``Likely to be 
Carcinogenic to Humans'' 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., Chronic exposure.
    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, and 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.
    The Agency estimated the average PCT for existing uses as follows: 
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://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the First Index Reservoir Screening Tool (FIRST) and 
Pesticide Root Zone Model Ground Water (PRZM-GW) models, the estimated 
drinking water concentrations (EDWCs) of clofentezine acute exposures 
are estimated to be 7.59 parts per billion (ppb) for surface water and 
less than 0.05 ppb for ground water. For chronic exposures for non-
cancer assessments, the EDWCs are estimated to be 0.062 ppb for surface 
water and less than 0.05 ppb for ground water. For chronic exposures 
for cancer assessments, the EDWC is estimated to be 0.025 ppb for 
surface.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration value of 0.062 ppb was used to 
assess the contribution to drinking water. For cancer dietary risk 
assessment, the water concentration value of 0.025 ppb was used to 
assess the contribution to drinking water.

[[Page 24725]]

    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 the 
cumulative effects of such chemicals, see EPA's website at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) margin of safety for infants 
and children in the case of threshold effects to account for prenatal 
and postnatal toxicity and the completeness of the database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the FQPA Safety 
Factor (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor.
    2. Prenatal and postnatal sensitivity. There is no concern for 
increased quantitative or qualitative susceptibility of the young 
following in utero (rats and rabbits) and pre-and post-natal exposure 
(rats) to clofentezine.
    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. EPA made conservative (protective) assumptions in the ground 
and surface water modeling used to assess exposure to clofentezine in 
drinking water. 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 less than 1% of the cPAD 
for the general U.S. population and all population subgroups. There are 
no residential uses for clofentezine.
    3. Short- and Intermediate-term risk. Short- and intermediate-term 
aggregate exposure takes into account short- and intermediate-term 
residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level). Short- and 
intermediate-term adverse effects were 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)-1 to the exposure value results in a cancer risk 
estimate of 3.9 x 10-7 for adults. 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 limit of quantitation (LOQ) and limit of detection 
(LOD) were determined to be 0.01 ppm and 0.003 ppm, respectively.
    The method may be requested from: Chief, Analytical Chemistry 
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 
20755-5350; telephone number: (410) 305-2905; email address: 
[email protected].

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. EPA 
considers the international maximum residue limits (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint

[[Page 24726]]

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 an MRL for clofentezine on guava.

C. Response to Comments

    One comment was received on the Notice of Filing expressing concern 
about pollution in cities due to human waste. The comment did not raise 
any issue related to the Agency's safety determination for clofentezine 
tolerances. The receipt of this comment is acknowledged; however, this 
comment is not relevant to this action.

D. Revisions to Petitioned-For Tolerances

    The Agency is establishing a tolerance for residues of clofentezine 
in or on guava at 3 ppm, rather than 1 ppm as requested. The storage 
stability data indicated a low average concurrent recovery of residues 
in guava. To account for the low storage stability recoveries, the 
Agency applied a factor of 3X to the average field trial values, 
resulting in a calculation of higher residues on guava and a need for a 
higher tolerance level.

V. Conclusion

    Therefore, a tolerance is established for residues of clofentezine, 
3,6-bis(2-chlorphenyl)-1,2,4,5-tetrazine, in or on guava at 3 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes a tolerance under FFDCA section 408(d) in 
response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this action has been 
exempted from review under Executive Order 12866, this action is not 
subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997), nor is this action considered a 
regulatory action under Executive Order 13771, entitled ``Reducing 
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3, 
2017). This action does not contain any information collections subject 
to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 
et seq.), nor does it require any special considerations under 
Executive Order 12898, entitled ``Federal Actions to Address 
Environmental Justice in Minority Populations and Low-Income 
Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal 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).
