II. Summary of Petitioned-For Tolerance
In the Federal Register of May 19, 2016 （81 FR 31581） （FRL-9946-02）， 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 5E8422） by Interregional Research Project Number 4 （IR-4）， Rutgers University, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540. The petition requested that 40 CFR 180.599 be amended by establishing tolerances for residues of the insecticide acequinocyl in or on avocado at 0.4 parts per million （ppm）； bean, dry, seed at 0.03 ppm; vegetable, cucurbit, group 9 at 0.2 ppm; tea, plucked leaves at 40 ppm; cherry subgroup 12-12A at 1.0 ppm; fruit, citrus, group 10-10 at 0.20 ppm; fruit, pome, group 11-10 at 0.40 ppm; nut, tree, group 14-12 at 0.02 ppm; and vegetable, fruiting, group 8-10 at 0.70 ppm. The petition also requested that upon establishment of the above tolerances, to remove the existing tolerances for cucumber at 0.15 ppm; melon, subgroup 9A at 0.15 ppm; cherry, sweet at 0.50 ppm; cherry, tart at 1.0 ppm; fruit, citrus, group 10 at 0.20 ppm; fruit, pome, group 11 at 0.40 ppm; nut, tree, group 14 at 0.02 ppm; pistachio at 0.02 ppm; vegetable, fruiting, group 8 at 0.70 ppm; and okra at 0.70 ppm. That document referenced a summary of the petition prepared by Arysta LifeScience, the registrant, which is available in the docket, http://www.regulations.gov. Comments were received on the notice of filing. EPA's response to these comments is discussed in Unit IV.C.
based upon review of the data supporting the petition, EPA has modified the levels at which some of the tolerances are being established. The reason for these changes 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 acequinocyl including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with acequinocyl 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 target organs of acequinocyl are the liver （hepatocyte vacuolization, brown pigmented cells and perivascular inflammatory cells in liver） and hematopoietic system （hemorrhage, increased clotting factor times and increased platelet counts）。 There was no evidence of neurotoxicity and immunotoxicity and there was no evidence of carcinogenic potential in either the rat or mouse, or in the genotoxicity and mutagenicity studies.
In rats and rabbits, there was no evidence of increased quantitative or qualitative fetal susceptibility. In both species there were clinical signs and gross necropsy findings seen in maternal animals at similar or lower doses than those producing resorptions. In rabbits, there were increased incidences of late resorptions at the highest dose tested. In the rat two-generation reproductive toxicity study, there was evidence of apparent increased quantitative postnatal susceptibility. Offspring effects at the mid- and high-doses consisted of swollen body parts, protruding eyes, clinical signs, delays in pupil development, and increased mortality occurring mainly after weaning. No parental effects were observed up to the highest dose tested; however, hematological parameters, such as changes in partial and activated partial Start Printed Page 5411thromboplastin times, were not measured in parental animals and changes in these parameters would have been expected at the same doses as offspring effects based on rat studies in the acequinocyl toxicological database. There were no effects on reproductive parameters.
Specific information on the studies received and the nature of the adverse effects caused by acequinocyl 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 http://www.regulations.gov in the document titled “Acequinocyl. Human Health Risk Assessment To Support the Petition for Tolerance for Residues in/on Dry Beans, Cucurbit Vegetables, Group 9, Avocado and Tea （Without U.S. Registration） and Crop Group Conversions for Citrus Fruit Group 10-10, Tree Nut Group 14-12, and Fruiting Vegetable Group 8-10” at page 30 in docket ID number EPA-HQ-OPP-2015-0829.
B. Toxicological Points of Departure/Levels of Concern
once a pesticide's toxicological profile is determined, EPA identifies toxicological points of departure （POD） and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed （the NOAEL） and the lowest dose at which adverse effects of concern are identified （the LOAEL）。 Uncertainty/safety factors are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose （PAD） or a reference dose （RfD）—and a safe margin of exposure （MOE）。 For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see http://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?assessing-human-health-risk-pesticides.
Since the last assessment for acequinocyl （Federal Register of April 13, 2016, （81 FR 21752） （FRL-9944-34））， the endpoints for acequinocyl were revisited and updated based upon the available data. An acute dietary endpoint for the general population has been selected to be consistent with current Agency practices. A summary of the updated toxicological endpoints for acequinocyl used for human risk assessment is shown in Table 1 of this unit.

UFA = extrapolation from animal to human （interspecies）。 UFH = potential variation in sensitivity among members of the human population （intraspecies）。
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary exposure to acequinocyl, EPA considered exposure under the petitioned-for tolerances as well as all existing acequinocyl tolerances in 40 CFR 180.599. EPA assessed dietary exposures from acequinocyl in food as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk assessments are performed for a food-use pesticide, if a toxicological study has indicated the possibility of an effect of concern occurring as a result of a 1-day or single exposure.
Such effects were identified for acequinocyl. In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture （USDA） 2003-2008 National Health and Nutrition Examination Survey, What We Eat in America, （NHANES/WWEIA）。 As to residue levels in food, EPA assumed tolerance level residues and 100 percent crop treated （PCT） for all proposed and registered uses.
ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 2003-2008 NHANES/WWEIA. As to residue levels in food, EPA assumed tolerance level residues and 100 PCT for all proposed and registered uses.
iii. Cancer. based on the data summarized in Unit III.A., EPA has concluded that acequinocyl does not pose a cancer risk to humans. Therefore, Start Printed Page 5412a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use anticipated residue or PCT information in the dietary assessment for acequinocyl. Tolerance level residues and 100 PCT were assumed for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for acequinocyl in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of acequinocyl. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?about-water-exposure-models-used-pesticide.
based on the Pesticide Root Zone Model/Exposure Analysis Modeling System （PRZM/EXAMS）， Provisional Cranberry Model, and Screening Concentration in Ground Water （SCI-GROW） Model, the estimated drinking water concentrations （EDWCs） of acequinocyl for acute exposures are estimated to be 6.69 parts per billion （ppb） for surface water and 3.6 × 10?3 ppb for ground water, and for chronic exposures are estimated to be 6.69 ppb for surface water and ≥3.6 × 10?3 ppb for ground water.
Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For acute dietary risk assessment, the water concentration value of 6.69 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 6.69 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）。
Acequinocyl is currently registered for the following uses that could result in residential exposures: use on ornamentals for landscapes, gardens, and trees. EPA assessed residential exposure using the following assumptions: There is a potential for residential exposure associated with handler （i.e., mixing, loading and applying）； however, all registered acequinocyl product labels with residential use sites （e.g., ornamentals for landscapes, gardens, and trees） require that handlers wear specific clothing （e.g., long-sleeve shirt/long pants） and/or use personal protective equipment （PPE）。 Therefore, the Agency has made the assumption that these products are not for homeowner use, and has not conducted a quantitative residential handler assessment.
only short-term post-application dermal exposure is anticipated for the registered residential uses. The quantitative exposure/risk assessment for residential post-application exposures assessed dermal exposures to adults for activities associated with gardening, dermal exposures to children （6 to <11 years old） for activities associated with playing in and around gardens and gardening, dermal exposures to adults associated with handling trees and retail plants, and dermal exposures to children （6 to <11 years old） for activities associated with playing in and around trees and retail plants.
Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?standard-operating-procedures-residential-pesticide.
4. Cumulative effects from substances with a common mechanism of toxicity. Section 408（b）（2）（D）（v） of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider “available information” concerning the cumulative effects of a particular pesticide's residues and “other substances that have a common mechanism of toxicity.”
EPA has not found acequinocyl to share a common mechanism of toxicity with any other substances, and acequinocyl does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that acequinocyl does not have a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's Web site at http://www2.epa.gov/?pesticide-science-and-assessing-pesticide-risks/?cumulative-assessment-risk-pesticides.
D. Safety Factor for Infants and Children
1. In general. Section 408（b）（2）（C） of FFDCA provides that EPA shall apply an additional tenfold （10X） margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the FQPA Safety Factor （SF）。 In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. There is no evidence of an increased quantitative or qualitative fetal susceptibility in rats or rabbits. In isolation, there was evidence of increased quantitative offspring susceptibility in the two-generation reproductive study; however, but the concern is low since: （1） The effects in pups are well characterized with a clear NOAEL; and （2） the effects are protected for by the selected endpoints. Therefore, there are no residual uncertainties for pre-/post-natal toxicity. Additionally, taking into consideration the full database, there would be no susceptibility to offspring since assessment of parental animals in the two-generation reproductive toxicity study were limited. If additional evaluations had been performed, including all hematological measurements, then it would be expected that effects on the hematopoietic system observed in the other oral rat studies would have been seen at the same doses eliciting offspring effects. Therefore, using a weight-of-evidence approach that puts the offspring findings in the two-generation reproductive toxicity study in context with the full toxicological database, there is no concern for susceptibility to offspring since parental toxicity would be anticipated at the same dose as offspring effects.
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 acequinocyl is complete.
ii. There is no indication that acequinocyl 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 of an increased quantitative or qualitative fetal susceptibility in rats or rabbits, but in isolation there was evidence of increased quantitative offspring susceptibility in the two-generation reproductive study. However, the Start Printed Page 5413concern is low for the reasons outlined above in section III.D.2.
iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and tolerance-level residues. EPA made conservative （protective） assumptions in the ground and surface water modeling used to assess exposure to acequinocyl in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children. These assessments will not underestimate the exposure and risks posed by acequinocyl.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute PAD （aPAD） and chronic PAD （cPAD）。 For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate MOE exists.
1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to acequinocyl will occupy 71% of the aPAD for children 1-2 years old, the population group receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to acequinocyl from food and water will utilize 70% of the cPAD for children 1-2 years old, the population group receiving the greatest exposure. based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of acequinocyl is not expected.
3. Short-term risk. Short-term aggregate exposure takes into account short-term residential exposure plus chronic exposure to food and water （considered to be a background exposure level）。 Acequinocyl is currently registered for uses that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to acequinocyl.
Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 1200 for adults and 890 for children 6-12 years old. Because EPA's level of concern for acequinocyl is a MOE of 100 or below, these MOEs are not of concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure takes into account intermediate-term residential exposure plus chronic exposure to food and water （considered to be a background exposure level）。
An intermediate-term adverse effect was identified; however, acequinocyl is not registered for any use patterns that would result in intermediate-term residential exposure. Intermediate-term risk is assessed based on intermediate-term residential exposure plus chronic dietary exposure. Because there is no intermediate-term residential exposure and chronic dietary exposure has already been assessed under the appropriately protective cPAD （which is at least as protective as the POD used to assess intermediate-term risk）， no further assessment of intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating intermediate-term risk for acequinocyl.
5. Aggregate cancer risk for U.S. population. based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, acequinocyl is not expected to pose a cancer risk to humans.
6. Determination of safety. based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to acequinocyl residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology （two high-performance liquid chromatography methods with tandem mass-spectroscopy detection （HPLC/MS/MS） for determining residues in/on fruit and nut commodities （Morse Methods Meth-133 and Meth-135） 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.
The Codex has not established any MRLs for acequinocyl.
C. Response to Comments
A comment was submitted by the Center for Biological Diversity and was primarily concerned about EPA's consideration of the impacts of acequinocyl on the environment, pollinators, and endangered species. This comment is not relevant to the Agency's evaluation of safety of the acequinocyl tolerances under section 408 of the FFDCA, which requires the Agency to evaluate the potential harms to human health, not effects on the environment.
Two other comments were submitted in response to the Notice of Filing that stated, in part, that this chemical “should not be used at all in America or anywhere in the world” and that “no residue should be permitted on any food or other plant.” The Agency understands the commenter's concerns and recognizes that some individuals believe that pesticides should be banned on agricultural crops. However, the existing legal framework provided by section 408 of the FFDCA states that tolerances may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. The citizens' comments appear to be directed at the underlying statute and not EPA's implementation of it; the citizens have made no contention that EPA has acted in violation of the statutory framework.
D. Revisions to Petitioned-For Tolerances
The petitioned-for tolerance of 0.4 for residues on avocado is being increased to 0.50 ppm as EPA corrected some residue levels in the field trials for degradation during storage and declared two of the trials to be replicates. The Start Printed Page 5414data that EPA used in Organization for Economic Co-operation and Development （OECD） Maximum Residue Limits （MRL） Tolerance Worksheet for avocado was thus slightly different from the petitioner's data. The tolerance level of 0.15 ppm for residues in dry beans is based upon the OECD MRL tolerance worksheet. The difference is based on EPA using slightly different residue levels that were corrected for degradation during storage. The tolerance level of 0.30 ppm for residues in/on cucurbit vegetables is based upon the OECD MRL tolerance worksheet. The difference is based on EPA using slightly different residue levels that were corrected for degradation during storage. The data that EPA used in MRL tolerance spreadsheet for summer squash was slightly different from the petitioner's data. Concerning the crop group conversions, the tolerance level for residues in/on citrus fruit was modified to be harmonized with the Canadian MRL.
V. Conclusion
Therefore, tolerances are established for residues of acequinocyl, including its metabolites and degradates, in or on avocado at 0.50 ppm; bean, dry, seed at 0.15 ppm; cherry, subgroup 12-12A at 1.0 ppm; fruit, citrus, group 10-10 at 0.35 ppm; fruit, pome, group 11-10 at 0.40 ppm; nut, tree, group 14-12 at 0.02 ppm; tea, plucked leaves at 40 ppm; vegetable, cucurbit, group 9 at 0.30 ppm; and vegetable, fruiting, group 8-10 at 0.70 ppm. In addition, the existing tolerances on cherry, sweet; cherry, tart; cucumber; fruit, citrus, group 10; fruit, pome, group 11; melon, subgroup 9A; nut, tree, group 14; okra; pistachio; and vegetable, fruiting, group 8 are removed as unnecessary since they are now covered by the new tolerances.
