II. Summary of Petitioned-For
Tolerance
In the Federal Register of February
11, 2020 (85 FR 7708) (FRL–10005–02),
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 9E8757) by Nissan
Chemical Corporation, 5–1, Nihonbashi
2-Chome Chuo-Ku, Tokyo 101–6119
Japan, c/o Lewis and Harrison, 2461
South Clark Street, Suite 710, Arlington,
VA 22202. The petition requested that
40 CFR part 180 be amended by
establishing tolerances for residues of
the insecticide fluxametamide,
including its metabolites and
degradates, in or on tea at 5 parts per
million (ppm). That document
referenced a summary of the petition
prepared by Nissan Chemical
Corporation c/o Lewis and Harrison, the
registrant, which is available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
Based upon review of the data
supporting the petition, EPA has revised
the commodity definition and is
establishing a tolerance for tea, dried
and tea, instant. 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
VerDate Sep<11>2014
15:56 Feb 16, 2021
Jkt 253001
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 fluxametamide
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with fluxametamide 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.
Fluxametamide belongs to a class of
compounds called isoxazolines, which
are potent inhibitors of g-aminobutyric
acid (GABA)-, glutamate-, and glycinegated chloride channels in insects.
However, this pesticidal mode of action
(MOA) does not seem to be operative in
mammals as neurotoxicity was not
found in either the acute or subchronic
neurotoxicity studies at the limit dose.
The available studies show different
organs can be affected. For the dietary
toxicity studies in rats (neurotoxicity
study, chronic/carcinogenicity, and
reproductive toxicity studies), a
common effect on the gastrointestinal
(GI) tract was observed. The effects
consisted of gross pathology (an
increase incidence of abnormally pale
color duodenum and jejunum) and
histopathology (increased incidence of
enterocyte epithelial vacuolation of the
jejunum). Most of the effects seen in the
subchronic neurotoxicity study were
reproduced in the combined chronic
and carcinogenicity study with
increased severity and at lower dose
level. In addition, consistent adverse
effects were found in the lung (aggregate
alveolar marcophages and cholesterol
cleft) and liver (centrilobular
hepatocellular vacuolation and
periportal hepatocellular vacuolation).
These adverse effects were present at a
dose as low as 9 mg/kg/day in the
carcinogenicity study.
Fluxametamide is classified as having
‘‘suggestive evidence of carcinogenic
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700
9863
potential’’ based on thyroid tumors in
male rats and liver tumors in male mice.
The reasons for this classification are (1)
both tumor types are driven by
adenomas, (2) these increased tumor
incidences are seen at the highest doses
tested (877 mg/kg/day for male mice
and 899 mg/kg/day for male rats); these
doses are approaching the limit dose
(1000 mg/kg/day) for a carcinogenicity
study, (3) there is no hyperplasia of the
liver in either male or female mice, (4)
no increase in treatment-related tumors
has been observed in female mice or
female rats, and (5) no genotoxicity is
observed in the required battery of
mutagenic studies. Due to the lack of
genotoxicity and the fact that the tumors
are seen only at doses more than 100fold above the chronic reference dose,
EPA has determined that a non-linear
approach relying on the chronic
reference dose (RfD) will adequately
account for all chronic toxicity,
including carcinogenicity, that could
result from exposure to fluxametamide.
The in-utero and perinatal treatment
with fluxametamide in rats resulted in
toxicity and increased quantitative
susceptibility in developing animals. In
the 2-generation reproduction study,
fluxametamide produced no parental
effect at the highest dose tested (19 mg/
kg/day), while at the same dose level
produced offspring effect which
consisted of the observation that the
pups had distended abdomens and
affected pups had to be sacrificed for
humane reason. The dermal toxicity
study did not show systemic toxicity at
the limit dose (1000 mg/kg/day).
Specific information on the studies
received and the nature of the adverse
effects caused by fluxametamide, as
well as the no-observed-adverse-effectlevel (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies, can be found at http:/
www.regulations.gov in document titled
‘‘Fluxametamide: Human Health Risk
Assessment to Support the
Establishment of a Tolerance without
U.S. Registration in/on Tea. First Food
Use’’ hereinafter ‘‘Fluxametamide
Human Health Risk Assessment’’ at
pages 16–22 in docket ID number EPA–
HQ–OPP–2019–0492.
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
E:\FR\FM\17FER1.SGM
17FER1
9864
Federal Register / Vol. 86, No. 30 / Wednesday, February 17, 2021 / Rules and Regulations
jbell on DSKJLSW7X2PROD with RULES
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticide.
A summary of the toxicological
endpoints for fluxametamide used for
human risk assessment can be found in
the Fluxametamide Human Health Risk
Assessment.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to fluxametamide, EPA
considered exposure under the
petitioned-for tolerances. EPA assessed
dietary exposures from fluxametamide
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 fluxametamide; therefore, a
quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used 2003–2008 food consumption
data from the United States Department
of Agriculture’s (USDA) National Health
and Nutrition Examination Survey,
What We Eat in America, (NHANES/
WWEIA). As to residue levels in food,
EPA assumed tolerance-level residues of
fluxametamide on tea and 100% crop
treated.
iii. Cancer. EPA determines whether
quantitative cancer exposure and risk
assessments are appropriate for a fooduse pesticide based on the weight of the
evidence from cancer studies and other
relevant data. Based on the data
VerDate Sep<11>2014
15:56 Feb 16, 2021
Jkt 253001
summarized in Unit III.A., EPA has
concluded that a nonlinear RfD
approach will adequately account for all
chronic toxicity, including
carcinogenicity, that could result from
exposure to fluxametimide. A separate
cancer dietary exposure and risk
assessment is not required. Cancer risk
was assessed using the same exposure
estimates as discussed in Unit III.C.1.ii.,
chronic exposure.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue and/or PCT
information in the dietary assessment
for fluxametamide. Tolerance level
residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking
water. EPA assumes that there is no
exposure through drinking water
because fluxametamide is not registered
for use in the United States. Because
residues are not expected in drinking
water, dietary risk estimates include
exposures from food only.
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).
Fluxametamide is not being proposed to
be 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.’’
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
fluxametamide and any other
substances and fluxametamide does not
appear to produce a toxic metabolite
produced by other substances. For the
purposes of this action, therefore, EPA
has not assumed that fluxametamide has
a common mechanism of toxicity with
other substances.
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
PO 00000
Frm 00028
Fmt 4700
Sfmt 4700
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 an increase in quantitative
susceptibility in two-generation
reproductive toxicity study in rats. In
this study, parental animals showed no
adverse effects at 19 mg/kg/day (highest
dose tested, HDT), whereas some pups
had to be euthanized due to distended
abdomen at the same dose. However,
the concern is low because there was a
clear NOAEL for the offspring effect (6
mg/kg/day) and the POD selected for
chronic dietary exposure assessment (1
mg/kg/day) is protective of the offspring
effects seen in the 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
fluxametamide is complete.
ii. There is no indication that
fluxametamide is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is evidence of an increase in
quantitative susceptibility in the 2generation reproductive toxicity study
in rats. In this study, parental animals
showed no adverse effects at 19 mg/kg/
day highest dose tested, (HDT), whereas
some pups had to be euthanized due to
distended abdomen at the same dose.
However, the concern is low because
there was a clear NOAEL for the
offspring effect (6 mg/kg/day) and the
POD selected for chronic dietary
exposure assessment (1 mg/kg/day) is
protective of the offspring effects seen in
the reproductive toxicity study. The
selected points of departure for risk
assessment are protective of the
quantitative increase in susceptibility
seen in the rat reproductive toxicity
study, for which a clear NOAEL and
LOAEL are established.
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. These
E:\FR\FM\17FER1.SGM
17FER1
Federal Register / Vol. 86, No. 30 / Wednesday, February 17, 2021 / Rules and Regulations
jbell on DSKJLSW7X2PROD with RULES
assessments will not underestimate the
exposure and risks posed by
fluxametamide.
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, fluxametamide 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 fluxametamide
from food only will utilize less than 1%
of the cPAD for all population
subgroups. There are no residential uses
for fluxametamide.
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). Because fluxametamide
is not registered in the United States,
the only exposures will be dietary, from
residues in or on imported tea;
therefore, no short-term or intermediateterm residential exposure is expected.
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-term risk), no further
assessment of short- or intermediateterm risk is necessary, and EPA relies on
the chronic dietary risk assessment for
evaluating short- and intermediate-term
risk for fluxametamide.
4. Aggregate cancer risk for U.S.
population. As stated in Unit III.A., EPA
has concluded that the chronic
reference dose (RfD) will adequately
account for all repeated exposure/
chronic toxicity, including
carcinogenicity, which could result
from exposure to fluxametamide. Based
VerDate Sep<11>2014
15:56 Feb 16, 2021
Jkt 253001
on the lack of chronic risk at regulated
levels of exposure, EPA concludes that
exposure to fluxametamide will not
pose an aggregate 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
fluxametamide residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(high-performance liquid
chromatography method with tandem
mass spectrometry detection (LC/MS/
MS), Method NCI–2012–101/NCI–2013–
017) 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 an
MRL for fluxametamide.
C. Revisions to Petitioned-For
Tolerances
The petition requested a tolerance for
residues of fluxametamide in or on tea.
Since dried tea is the commodity that
enters commerce, EPA is establishing
the tolerance for the processed
commodity tea, dried rather than tea,
plucked leaves. EPA is also establishing
a tolerance for tea, instant, which is
another processed commodity of tea,
plucked leaves, and EPA has
PO 00000
Frm 00029
Fmt 4700
Sfmt 4700
9865
determined that the same tolerance of 5
ppm is appropriate for instant tea.
V. Conclusion
Therefore, tolerances are established
for residues of fluxametamide,
including its metabolites and
degradates, in or on tea, dried at 5 ppm
and tea, instant at 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), 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

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

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

II. Summary of Petitioned-For Tolerance
In the Federal Register of February 11, 2020 (85 FR 7708) (FRL-
10005-02), 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
9E8757) by Nissan Chemical Corporation, 5-1, Nihonbashi 2-Chome Chuo-
Ku, Tokyo 101-6119 Japan, c/o Lewis and Harrison, 2461 South Clark
Street, Suite 710, Arlington, VA 22202. The petition requested that 40
CFR part 180 be amended by establishing tolerances for residues of the
insecticide fluxametamide, including its metabolites and degradates, in
or on tea at 5 parts per million (ppm). That document referenced a
summary of the petition prepared by Nissan Chemical Corporation c/o
Lewis and Harrison, the registrant, which is available in the docket,
https://www.regulations.gov. There were no comments received in response
to the notice of filing.
Based upon review of the data supporting the petition, EPA has
revised the commodity definition and is establishing a tolerance for
tea, dried and tea, instant. 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 fluxametamide including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with fluxametamide
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.
Fluxametamide belongs to a class of compounds called isoxazolines,
which are potent inhibitors of [gamma]-aminobutyric acid (GABA)-,
glutamate-, and glycine-gated chloride channels in insects. However,
this pesticidal mode of action (MOA) does not seem to be operative in
mammals as neurotoxicity was not found in either the acute or
subchronic neurotoxicity studies at the limit dose.
The available studies show different organs can be affected. For
the dietary toxicity studies in rats (neurotoxicity study, chronic/
carcinogenicity, and reproductive toxicity studies), a common effect on
the gastrointestinal (GI) tract was observed. The effects consisted of
gross pathology (an increase incidence of abnormally pale color
duodenum and jejunum) and histopathology (increased incidence of
enterocyte epithelial vacuolation of the jejunum). Most of the effects
seen in the subchronic neurotoxicity study were reproduced in the
combined chronic and carcinogenicity study with increased severity and
at lower dose level. In addition, consistent adverse effects were found
in the lung (aggregate alveolar marcophages and cholesterol cleft) and
liver (centrilobular hepatocellular vacuolation and periportal
hepatocellular vacuolation). These adverse effects were present at a
dose as low as 9 mg/kg/day in the carcinogenicity study.
Fluxametamide is classified as having ``suggestive evidence of
carcinogenic potential'' based on thyroid tumors in male rats and liver
tumors in male mice. The reasons for this classification are (1) both
tumor types are driven by adenomas, (2) these increased tumor
incidences are seen at the highest doses tested (877 mg/kg/day for male
mice and 899 mg/kg/day for male rats); these doses are approaching the
limit dose (1000 mg/kg/day) for a carcinogenicity study, (3) there is
no hyperplasia of the liver in either male or female mice, (4) no
increase in treatment-related tumors has been observed in female mice
or female rats, and (5) no genotoxicity is observed in the required
battery of mutagenic studies. Due to the lack of genotoxicity and the
fact that the tumors are seen only at doses more than 100-fold above
the chronic reference dose, EPA has determined that a non-linear
approach relying on the chronic reference dose (RfD) will adequately
account for all chronic toxicity, including carcinogenicity, that could
result from exposure to fluxametamide.
The in-utero and perinatal treatment with fluxametamide in rats
resulted in toxicity and increased quantitative susceptibility in
developing animals. In the 2-generation reproduction study,
fluxametamide produced no parental effect at the highest dose tested
(19 mg/kg/day), while at the same dose level produced offspring effect
which consisted of the observation that the pups had distended abdomens
and affected pups had to be sacrificed for humane reason. The dermal
toxicity study did not show systemic toxicity at the limit dose (1000
mg/kg/day).
Specific information on the studies received and the nature of the
adverse effects caused by fluxametamide, 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 titled ``Fluxametamide: Human Health
Risk Assessment to Support the Establishment of a Tolerance without
U.S. Registration in/on Tea. First Food Use'' hereinafter
``Fluxametamide Human Health Risk Assessment'' at pages 16-22 in docket
ID number EPA-HQ-OPP-2019-0492.
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
[[Page 9864]]
of reference values for risk assessment. PODs are developed based on a
careful analysis of the doses in each toxicological study to determine
the dose at which no adverse effects are observed (the NOAEL) and the
lowest dose at which adverse effects of concern are identified (the
LOAEL). Uncertainty/safety factors are used in conjunction with the POD
to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticide.
A summary of the toxicological endpoints for fluxametamide used for
human risk assessment can be found in the Fluxametamide Human Health
Risk Assessment.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fluxametamide, EPA considered exposure under the
petitioned-for tolerances. EPA assessed dietary exposures from
fluxametamide 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 fluxametamide; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used 2003-2008 food consumption data from the United
States Department of Agriculture's (USDA) National Health and Nutrition
Examination Survey, What We Eat in America, (NHANES/WWEIA). As to
residue levels in food, EPA assumed tolerance-level residues of
fluxametamide on tea and 100% crop treated.
iii. Cancer. EPA determines whether quantitative cancer exposure
and risk assessments are appropriate for a food-use pesticide based on
the weight of the evidence from cancer studies and other relevant data.
Based on the data summarized in Unit III.A., EPA has concluded that a
nonlinear RfD approach will adequately account for all chronic
toxicity, including carcinogenicity, that could result from exposure to
fluxametimide. A separate cancer dietary exposure and risk assessment
is not required. Cancer risk was assessed using the same exposure
estimates as discussed in Unit III.C.1.ii., chronic exposure.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue and/or PCT information in the
dietary assessment for fluxametamide. Tolerance level residues and/or
100 PCT were assumed for all food commodities.
2. Dietary exposure from drinking water. EPA assumes that there is
no exposure through drinking water because fluxametamide is not
registered for use in the United States. Because residues are not
expected in drinking water, dietary risk estimates include exposures
from food only.
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). Fluxametamide is not
being proposed to be 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.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to fluxametamide and any
other substances and fluxametamide does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
action, therefore, EPA has not assumed that fluxametamide has a common
mechanism of toxicity with other substances.
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 an increase in
quantitative susceptibility in two-generation reproductive toxicity
study in rats. In this study, parental animals showed no adverse
effects at 19 mg/kg/day (highest dose tested, HDT), whereas some pups
had to be euthanized due to distended abdomen at the same dose.
However, the concern is low because there was a clear NOAEL for the
offspring effect (6 mg/kg/day) and the POD selected for chronic dietary
exposure assessment (1 mg/kg/day) is protective of the offspring
effects seen in the 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 fluxametamide is complete.
ii. There is no indication that fluxametamide is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is evidence of an increase in quantitative
susceptibility in the 2-generation reproductive toxicity study in rats.
In this study, parental animals showed no adverse effects at 19 mg/kg/
day highest dose tested, (HDT), whereas some pups had to be euthanized
due to distended abdomen at the same dose. However, the concern is low
because there was a clear NOAEL for the offspring effect (6 mg/kg/day)
and the POD selected for chronic dietary exposure assessment (1 mg/kg/
day) is protective of the offspring effects seen in the reproductive
toxicity study. The selected points of departure for risk assessment
are protective of the quantitative increase in susceptibility seen in
the rat reproductive toxicity study, for which a clear NOAEL and LOAEL
are established.
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. These
[[Page 9865]]
assessments will not underestimate the exposure and risks posed by
fluxametamide.
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,
fluxametamide 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
fluxametamide from food only will utilize less than 1% of the cPAD for
all population subgroups. There are no residential uses for
fluxametamide.
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). Because fluxametamide
is not registered in the United States, the only exposures will be
dietary, from residues in or on imported tea; therefore, no short-term
or intermediate-term residential exposure is expected. 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-
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 fluxametamide.
4. Aggregate cancer risk for U.S. population. As stated in Unit
III.A., EPA has concluded that the chronic reference dose (RfD) will
adequately account for all repeated exposure/chronic toxicity,
including carcinogenicity, which could result from exposure to
fluxametamide. Based on the lack of chronic risk at regulated levels of
exposure, EPA concludes that exposure to fluxametamide will not pose an
aggregate 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 fluxametamide residues.

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 an MRL for fluxametamide.
C. Revisions to Petitioned-For Tolerances
The petition requested a tolerance for residues of fluxametamide in
or on tea. Since dried tea is the commodity that enters commerce, EPA
is establishing the tolerance for the processed commodity tea, dried
rather than tea, plucked leaves. EPA is also establishing a tolerance
for tea, instant, which is another processed commodity of tea, plucked
leaves, and EPA has determined that the same tolerance of 5 ppm is
appropriate for instant tea.
V. Conclusion
Therefore, tolerances are established for residues of
fluxametamide, including its metabolites and degradates, in or on tea,
dried at 5 ppm and tea, instant at 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), 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
[[Page 9866]]
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).

Sec. 180.715 Fluxametamide; tolerances for residues.
(a) General. Tolerances are established for residues of the
insecticide fluxametamide, including its metabolites and degradates, in
or on the commodities to Table 1 of this section. Compliance with the
tolerance levels specified in Table 1 is to be determined by measuring
only residues of fluxametamide, 4-[5-(3,5-dichlorophenyl)-4,5-dihydro-
5-(trifluoromethyl)-3-isoxazolyl]-N-[(methoxyamino)methylene]-2-
methylbenzamide in or on the commodities:
