II. Summary of Petitioned-For Tolerance

    In the Federal Register of March 6, 2018 (83 FR 9471) (FRL-9973-
27), 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 
7F8623) by Nippon Soda Co., Ltd c/o Nisso America, Inc., 88 Pine 
Street, 14th Floor, New York, NY 10005. The petition requested that 40 
CFR part 180 be amended by establishing tolerances for residues of the 
fungicide picarbutrazox, 1,1-Dimethylethyl N-(6-((((Z)-((1-methyl-1H-
tetrazol-5-yl) phenylmethylene) amino)oxy)methyl)-2-
pyridinyl)carbamate, in or on corn, forage at 0.01 parts per million 
(ppm); corn, grain at 0.01 ppm; corn, stover at 0.01 ppm; corn, sweet, 
forage at 0.01 ppm; corn, sweet, kernel plus cob with husks removed at 
0.01 ppm; corn, sweet, stover at 0.01 ppm; crop group 9, cucurbit 
vegetables at 0.20 ppm, crop subgroup 4-16A, leafy greens at 10 ppm; 
popcorn, grain at 0.01 ppm; soybean, forage at 0.01 ppm; soybean, hay 
at 0.01 ppm and soybean, seed at 0.01 ppm. That document referenced a 
summary of the petition prepared by Nippon Soda Co., Ltd c/o Nisso 
America, the registrant, which is available in the docket, http://www.regulations.gov. Nine comments were received on the notice of 
filing. However, they were not germane to this submission.
    Based upon review of the data supporting the petition, EPA is 
establishing, in accordance with section 408(d)(4)(a)(i), tolerances 
that vary in some respects from what the petitioner requested. Also, 
EPA is not establishing tolerances for Crop Group 9, Cucurbit 
Vegetables and Crop Subgroup 4-16A, Leafy Greens, as the petitioner 
withdrew the request for those tolerances after submitting the 
petition. The Agency's underlying rationale for those variations 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 picarbutrazox including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with picarbutrazox 
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 organs for picarbutrazox are the liver and the 
thyroid gland across species and durations (except acute). The rat was 
the most sensitive species, followed by the mouse and the dog. Both the 
liver and the thyroid showed increases in organ weights and 
histopathological changes. In the liver, changes included hepatocyte 
hypertrophy, periportal vacuolation, cytoplasmic inclusions, and portal 
inflammatory cell infiltration. In the thyroid, there were increased 
incidences of thyroid hypertrophy which corresponded with increased 
thyroid weights in both parental animals and neonates. Disruption of 
thyroid hormones was also observed across the guideline studies, for 
the short-term and long-term durations in rats (alterations in 
triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone 
(TSH)). Thyroid follicular tumors were observed in rats following 2 
years of oral exposure. No treatment-related effects were observed in 
mice following 78 weeks of exposure. There is no evidence of 
genotoxicity or mutagenicity in the picarbutrazox hazard database.
    There is no evidence of increased prenatal susceptibility in rats 
or rabbits or postnatal susceptibility in rats. There were no adverse 
fetal or maternal effects in the available developmental toxicity 
studies in rats or rabbits. Both studies tested up to the limit dose. 
In the multi-generation reproductive study, adverse thyroid effects 
were observed in the parental animals and occurred at doses lower than 
offspring effects. There were no adverse reproductive effects up to the 
highest dose tested (46/63 mg/kg/day).

[[Page 12831]]

    Subchronic studies in rats were performed for the numerous plant 
metabolites generated from parent picarbutrazox. All were less toxic 
than the parent molecule. No signs of neurotoxicity were observed in 
the acute neurotoxicity study up to the limit dose (2,000 mg/kg/day). 
No dermal toxicity was observed in rats up to the limit dose (1,000 mg/
kg/day). Picarbutrazox is categorized as having low acute lethality 
through the oral, dermal, and inhalation routes. It is minimally 
irritating to the eye and is neither a dermal irritant nor sensitizer.
    In accordance with the EPA's Final Guidelines for Carcinogen Risk 
Assessment (March 2005), the Agency classified picarbutrazox as 
``Suggestive Evidence of Carcinogenic Potential'' based on an increase 
in the incidence of thyroid follicular cell tumors, driven by adenomas 
in male and female rats and combined thyroid follicular adenomas/
carcinomas in male rats. There is no concern for genotoxicity or 
mutagenicity and no treatment-related tumors were observed in mice. 
Based on its weight-of-evidence analysis, the Agency has determined 
that quantification of risk using a non-linear approach (i.e., chronic 
reference dose (cRfD)) will adequately account for all chronic 
toxicity, including potential carcinogenicity, that could result from 
exposure to picarbutrazox. The chronic reference dose is several times 
lower than the dose at which tumors were observed.
    Specific information on the studies received and the nature of the 
adverse effects caused by picarbutrazox 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 ``Picarbutrazox. Human Health Risk 
Assessment in Support of a New Active Ingredient for Use on Corn and 
Soybean Seed and Turf'', dated December 18, 2020, hereinafter 
``Picarbutrazox Human Health Risk Assessment'' in docket ID number EPA-
HQ-OPP-2017-0653.

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-pesticide.
    A summary of the toxicological endpoints for picarbutrazox used for 
human risk assessment can be found on pages 19-20 in the Picarbutrazox 
Human Health Risk Assessment.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to picarbutrazox, EPA considered exposure under the 
petitioned-for tolerances. EPA assessed dietary exposures from 
picarbutrazox 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 picarbutrazox; 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) National Health and Nutrition 
Examination Survey, What We Eat in America, (NHANES/WWEIA). As to 
residue levels in food, EPA conducted an unrefined chronic dietary 
exposure assessment using tolerance-level residues, 100 percent crop 
treated (PCT), and default processing factors.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that a nonlinear RfD approach is appropriate for assessing 
cancer risk to picarbutrazox. Quantification of risk using a non-linear 
approach (i.e., cRfD) will adequately account for all chronic toxicity, 
including potential carcinogenicity, that could result from exposure to 
picarbutrazox.
    iv. Anticipated residue and percent crop treated (PCT) information. 
EPA did not use anticipated residue and/or PCT information in the 
dietary assessment for picarbutrazox. Tolerance level residues and/or 
100 PCT were assumed for all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for picarbutrazox in drinking water. These simulation models 
take into account data on the physical, chemical, and fate/transport 
characteristics of picarbutrazox. 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.
    Using the Pesticides in Water Calculator (PWC) ver. 1.52, EPA 
calculated the estimated drinking water concentrations (EDWCs) of 
picarbutrazox for chronic exposures in surface and ground water. The 
groundwater estimates were significantly lower. EPA used the modeled 
EDWC of 2.56 ppb directly in dietary exposure model to account for the 
contribution of picarbutrazox residues in drinking water for the 
chronic dietary risk assessment.
    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). Picarbutrazox is 
currently proposed for turf uses that could result in residential 
exposures. EPA assessed residential exposure using the following 
assumptions: There is the potential for post-application exposure for 
adults and children following turf treatments made by professional 
applicators with picarbutrazox. A dermal exposure assessment was not 
quantitatively conducted because a dermal POD was not selected. The 
quantitative exposure/risk assessment for residential post-application 
exposures is based only on incidental oral scenarios for children 1 to 
<2 years old from hand to mouth activities on treated turf. Post-
application exposure and risk estimates indicate that the short-term 
incidental oral MOEs, ranging from 970 to 360,000, are not of concern 
(i.e., MOEs >=30). Further information regarding EPA standard 
assumptions and generic

[[Page 12832]]

inputs for residential exposures may be found at https://www.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 picarbutrazox to share a common mechanism of 
toxicity with any other substances, and picarbutrazox does not appear 
to produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
picarbutrazox 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 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 
increased prenatal susceptibility in rats or rabbits or postnatal 
susceptibility in rats, with no adverse effects observed in the 
developmental toxicity studies.
    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 picarbutrazox is complete.
    ii. There is no indication that picarbutrazox 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 picarbutrazox results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT, tolerance-level residues, default processing factors, and 
modeled drinking water estimates. EPA made conservative (protective) 
assumptions in the ground and surface water modeling used to assess 
exposure to picarbutrazox in drinking water. EPA used similarly 
conservative assumptions to assess post-application exposure of 
children as well as incidental oral exposure of toddlers. These 
assessments will not underestimate the exposure and risks posed by 
picarbutrazox.

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). 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, 
picarbutrazox 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 
picarbutrazox from food and water will utilize <1% of the cPAD for all 
infants (<1 year 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 
picarbutrazox is not expected.
    3. Short-term and Intermediate-term risk. Short-term and 
intermediate-term aggregate exposure takes into account short-term or 
intermediate-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level). Picarbutrazox 
is currently proposed for uses that could result in short-term and 
intermediate-term residential exposure, and the Agency has determined 
that it is appropriate to aggregate chronic exposure through food and 
water with short-term or intermediate-term residential exposures to 
picarbutrazox.
    Using the exposure assumptions described in this unit for short-
term and intermediate-term exposures, EPA has concluded the combined 
short-term or intermediate-term food, water, and residential exposures 
result in aggregate MOE of 950 for children 1 to <2 years old from 
dietary (food and drinking water) and incidental oral exposure from 
hand-to-mouth activities from post-application exposure to turf 
applications. Because EPA's level of concern for picarbutrazox is an 
MOE of 30 or below, these MOEs are not of concern.
    4. Aggregate cancer risk for U.S. population. As stated in Unit 
III.A., a separate cancer analysis was not conducted as the chronic 
assessment adequately accounts for all chronic toxicity, including 
potential carcinogenicity. Based on the lack of chronic risk, EPA 
concludes that aggregate exposure to picarbutrazox will not pose a 
cancer risk.
    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 picarbutrazox residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (liquid chromatography with tandem 
mass spectroscopy (LC/MS/MS) and high-performance liquid chromatography 
(HPLC/MS/MS)) is available to enforce the tolerance expression.

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,

[[Page 12833]]

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.
    Picarbutrazox is a new active ingredient, and no maximum residue 
limits (MRLs) have yet been established by Codex.

C. Revisions to Petitioned-For Tolerances

    The Agency is establishing tolerances for picarbutrazox using 
tolerance expression and commodity definitions that conform to current 
practices. Additionally, the Agency is establishing a tolerance on 
corn, pop, stover and corn, field, stover; the petitioner requested a 
tolerance on ``corn, stover'', but the correct terminology is ``corn, 
pop, stover'' and ``corn, field, stover''.

V. Conclusion

    Therefore, tolerances are established for residues of 
picarbutrazox, 1,1-Dimethylethyl N-(6-((((Z)-((1-methyl-1H-tetrazol-5-
yl) phenylmethylene) amino)oxy)methyl)-2-pyridinyl)carbamate, in or on 
corn, field, forage at 0.01 ppm; corn, field, grain at 0.01 ppm; corn, 
field, stover at 0.01 ppm; corn, pop, grain at 0.01 ppm; corn, pop, 
stover at 0.01 ppm; corn, sweet, forage at 0.01 ppm; corn, sweet, 
kernel plus cob with husks removed at 0.01 ppm; corn, sweet, stover at 
0.01 ppm; soybean, forage at 0.01 ppm; soybean, hay at 0.01 ppm and 
soybean, seed at 0.01 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), nor is it 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 tolerances in 
this final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or Tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
Tribal Governments, on the relationship between the National Government 
and the States or Tribal Governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian Tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000) do not apply to this action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 272 note).
