II. Summary of Petitioned-For Tolerance

    In the Federal Register of March 4, 2015 (80 FR 11611) (FRL-9922-
68), 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 
4E8298) by IR-4, 500 College Road East, Suite 201W, Princeton, NJ 
08540. The petition requested that 40 CFR part 180 be amended by 
establishing tolerances for residues of the insecticide 
methoxyfenozide, (3-methoxy-2-methylbenzoic acid 2-(3,5-
dimethylbenzoyl)-2-(1,1-dimethylethyl) hydrazide), under paragraph (a) 
in or on: Chive, fresh leaves at 30.0 parts per million (ppm); fruit, 
stone, group 12-12, except plum, prune, fresh at 3.0 ppm; and nut, 
tree, group 14-12 at 0.10 ppm. The petition also proposed the following 
tolerances under paragraph (a) be removed upon approval of the proposed 
tolerances listed above: Fruit, stone, group 12, except plum, prune, 
fresh at 3.0 ppm; nut, tree, group 14 at 0.10 ppm; pistachio at 0.10 
ppm; and in paragraph (d), chive at 4.5 ppm be removed. The petition 
additionally

[[Page 65965]]

requested to amend the tolerances in 40 CFR 180.544 for residues of 
methoxyfenozide in or on onion, green, subgroup 3-07B at 5.0 ppm to 
onion, green, subgroup 3-07B, except chive at 5.0 ppm; and herb 
subgroup 19A, except chive at 400 ppm to herb subgroup 19A, except 
chive, fresh leaves at 400 ppm. That document referenced a summary of 
the petition prepared on behalf of IR-4 by Dow AgroSciences LLC, the 
registrant, which is available in the docket, http://www.regulations.gov. No FFDCA-related comments were received on the 
notice of filing.
    Based upon review of the data supporting the petition, EPA has 
determined that the amended tolerance on onion, green, subgroup 3-07B, 
except chive should be established in or on onion, green, subgroup 3-
07B, except chive, fresh leaves. The reasons for these changes are 
explained in Unit IV.C.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue . . 
. .''
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for methoxyfenozide including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with methoxyfenozide 
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.
    Many of the available short-term or subchronic toxicity studies on 
methoxyfenozide showed little or no toxicity. The main target organs 
identified from the toxicity studies in the rat and dog were the liver, 
thyroid, and red blood cells (RBCs). The most consistent findings 
across species and studies were transiently decreased RBC parameters 
and increased liver, thyroid, adrenal, and spleen weights. Increases in 
thyroid and adrenal weights were observed in the rat chronic oral 
study. Thyroid weights were also increased in the dog following chronic 
exposure. However, no accompanying histopathology was observed.
    Acute and subchronic oral neurotoxicity studies in the rat did not 
show evidence of potential neurotoxicity. In the acute study, decreased 
hindlimb grip strength on day 0 was reported in males. This finding was 
only observed at the limit dose in males and was not observed in the 
subchronic neurotoxicity study and was therefore not considered 
evidence of neurotoxicity. No clinical signs of neurotoxicity or 
neurohistopathology were observed in other guideline studies.
    No maternal or developmental effects were observed in either the 
rat or rabbit oral developmental toxicity studies. In the rat 2-
generation reproductive toxicity study, parental effects were limited 
to increased liver weight and microscopic periportal hypertrophy. No 
offspring or reproductive toxicity was observed. In a 28-day dietary 
immunotoxicity study in the rat, no immunotoxicity was observed, and 
the only observed effect was increased liver weights.
    There was no evidence of carcinogenicity in the rat dietary 24-
month chronic toxicity/carcinogenicity study or the mouse dietary 18-
month carcinogenicity study. No mutagenic or clastogenic potential was 
observed in the battery of genotoxicity studies on methoxyfenozide. 
Based on these findings, methoxyfenozide is classified as not likely to 
be carcinogenic to humans.
    Specific information on the studies received and the nature of the 
adverse effects caused by methoxyfenozide 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 document, ``Methoxyfenozide. Human Health Draft 
Risk Assessment for Registration Review and New Use Risk Assessment to 
Support the Registration of Proposed Use on Chives, and Crop Group 
Expansions for Stone Fruit and Tree Nuts'' in pp. 42-47 in docket ID 
number EPA-HQ-OPP-2014-0591.

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 the NOAEL and the LOAEL are identified. 
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://www.epa.gov/pesticides/factsheets/riskassess.htm. A summary of the toxicological 
endpoints for methoxyfenozide used for human risk assessment is 
discussed in Table 1 of Unit III.B. of the final rule published in the 
Federal Register of August 27, 2014 (79 FR 51103) (FRL-9913-99).

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to methoxyfenozide, EPA considered exposure under the 
petitioned-for tolerances as well as all existing methoxyfenozide 
tolerances in 40 CFR 180.544. EPA assessed dietary exposures from 
methoxyfenozide in food as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk 
assessments

[[Page 65966]]

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 methoxyfenozide; 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 USDA under the 
National Health and Nutrition Examination Survey, What We Eat in 
America (NHANES/WWEIA), 2003 to 2008. As to residue levels in food, EPA 
used tolerance-level residues and the assumption of 100 percent crop 
treated (PCT) for all existing and proposed commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that methoxyfenozide does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue and/or PCT information in the dietary assessment 
for methoxyfenozide. Tolerance level residues and/or 100 PCT were 
assumed for all food commodities.
    2. Dietary exposure from drinking water. The residues of concern in 
drinking water are methoxyfenozide and the degradates RH-117,236 and 
RH-131,154, which are only present at low concentrations. The Agency 
used screening-level water exposure models in the dietary exposure 
analysis and risk assessment for methoxyfenozide and its degradates in 
drinking water. These simulation models take into account data on the 
physical, chemical, and fate/transport characteristics of 
methoxyfenozide and its degradates. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at http://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the FQPA Index Reservoir Screening Tool (FIRST), Screening 
Concentration in Ground Water (SCI-GROW), and the Pesticide Root Zone 
Model Ground Water (PRZM GW) models, the estimated drinking water 
concentrations (EDWCs) of methoxyfenozide and its degradates for 
chronic exposures for non-cancer assessments are estimated to be 7.57 
parts per billion (ppb) for surface water and 214 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 214 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). Methoxyfenozide is 
currently registered for use on ornamentals in and around home gardens, 
which could result in residential exposures. EPA assessed residential 
exposure using the following assumptions: Residential handlers were 
assessed for potential short-term inhalation exposures from mixing, 
loading, and applying methoxyfenozide. A quantitative dermal assessment 
for residential handlers was not conducted since there is no systemic 
toxicity associated with dermal exposures to methoxyfenozide. Adult 
post-application exposures were not quantitatively assessed since no 
dermal hazard was identified for methoxyfenozide and inhalation 
exposures are typically negligible in outdoor settings. Furthermore, 
the inhalation exposure assessment performed for residential handlers 
is representative of worse case inhalation exposures and is considered 
protective for post-application inhalation exposure scenarios.
    Post-application oral exposure to children is not expected since 
the extent to which young children engage in activities associated with 
areas where treated ornamentals are grown (or utilize these areas for 
prolonged periods of play) is low. Therefore, an incidental oral post-
application exposure assessment was not conducted. Further information 
regarding EPA standard assumptions and generic inputs for residential 
exposures may be found at http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
    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 methoxyfenozide to share a common mechanism of 
toxicity with any other substances, and methoxyfenozide does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
methoxyfenozide 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://www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) margin of safety for infants 
and children in the case of threshold effects to account for prenatal 
and postnatal toxicity and the completeness of the database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the Food Quality 
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA 
either retains the default value of 10X, or uses a different additional 
safety factor when reliable data available to EPA support the choice of 
a different factor.
    2. Prenatal and postnatal sensitivity. There is no evidence of 
qualitative or quantitative susceptibility of the developing fetus or 
offspring, based on the developmental and reproductive toxicity study 
results for methoxyfenozide. No developmental toxicity was observed in 
either the rat or rabbit developmental toxicity studies, and there was 
no evidence of offspring or reproductive toxicity in the rat 2-
generation reproductive toxicity study.
    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 methoxyfenozide is complete.
    ii. There is no indication that methoxyfenozide is a neurotoxic 
chemical and there is no need for a developmental neurotoxicity study 
or additional uncertainty factors (UFs) to account for neurotoxicity.
    iii. There is no evidence that methoxyfenozide 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 dietary food exposure assessment was performed 
based on 100 PCT and tolerance-level residues. EPA

[[Page 65967]]

made conservative (protective) assumptions in the ground and surface 
water modeling used to assess exposure to methoxyfenozide in drinking 
water. Based on the discussion Unit III.C.3., regarding residential use 
patterns, EPA does not expect residential uses of methoxyfenozide to 
result in postapplication exposure of children or incidental oral 
exposures of toddlers. These assessments will not underestimate the 
exposure and risks posed by methoxyfenozide.

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, 
methoxyfenozide 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 
methoxyfenozide from food and water will utilize 84% of the cPAD for 
children 1 to 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 
methoxyfenozide 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). 
Methoxyfenozide 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 methoxyfenozide.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in an aggregate MOE of 540. Because 
EPA's level of concern for methoxyfenozide 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, 
methoxyfenozide 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 methoxyfenozide.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, methoxyfenozide 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 methoxyfenozide residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology using high performance liquid 
chromatography (HPLC), with either tandem mass spectrometric detection 
(LC-MS/MS), or ultraviolet detection (UV) 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 a MRL for methoxyfenozide in or on 
chive or the commodities associated with herb subgroup 19A or green 
onion subgroup 3-07B. Codex has established an MRL in or on tree nuts 
at 0.1 milligram/kilogram (mg/kg), which is harmonized with the 
recommended tolerance of 0.10 ppm in or on tree nut crop group 14-12. 
However, Codex has established a tolerance in or on stone fruit at 2 
mg/kg that cannot be harmonized with the EPA tolerance in or on stone 
fruit group 12-12, except plum, prune, fresh at 3.0 ppm because the 
Organization for Economic Cooperation and Development (OECD) tolerance 
calculations that EPA uses to calculate U.S. tolerance levels result in 
a tolerance that is higher than the Codex MRL, and reduction of the 
tolerance would result in the risk of violative residues resulting from 
proper use according to label directions.

C. Revisions to Petitioned-For Tolerances

    Based on the data supporting the petition, the Agency determined 
that the petitioned-for tolerance on chive, fresh leaves at 30.0 ppm 
should be established in or on chive, fresh leaves at 30 ppm because 
EPA establishes tolerances using whole numbers for tolerances of 10 ppm 
or more, per the OECD tolerance calculation procedures. The Agency also 
determined that the petitioned-for-amended tolerance in or on onion, 
green, subgroup 3-07B, except chive should be established in or on 
onion, green, subgroup 3-07B, except chive, fresh leaves. This is due 
to the fact that only chive, fresh leaves are included in subgroup 3-
07B, and the Agency is establishing a separate tolerance for chive, 
fresh leaves at 30 ppm.

V. Conclusion

    Therefore, tolerances are established for residues of 
methoxyfenozide, (3-methoxy-2-methylbenzoic acid 2-(3,5-

[[Page 65968]]

dimethylbenzoyl)-2-(1,1-dimethylethyl) hydrazide), in or on chive, 
fresh leaves at 30 ppm; fruit, stone, group 12-12, except plum, prune, 
fresh at 3.0 ppm; herb subgroup 19A, except chive, fresh leaves at 400 
ppm; onion, green, subgroup 3-07B, except chive, fresh leaves at 5.0 
ppm; and nut, tree, group 14-12 at 0.10 ppm. This rule additionally 
removes the established tolerances in or on fruit, stone, group 12, 
except plum, prune, fresh at 3.0 ppm; herb subgroup 19A, except chive 
at 400 ppm; nut, tree, group 14 at 0.10 ppm; onion, green, subgroup 3-
07B at 5.0 ppm; pistachio at 0.10 ppm; and in paragraph (d)(2), chive 
at 4.5 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) in 
response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this action has been 
exempted from review under Executive Order 12866, this action is not 
subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any 
information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any 
special considerations under Executive Order 12898, entitled ``Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the tolerance in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
tribal governments, on the relationship between the national government 
and the States or tribal governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000) do not apply to this action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
