II. Summary of Petitioned-For
Tolerance
In the Federal Register of May 29,
2020 (85 FR 32338) (FRL–10009–84),
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 9F8801) by
Nippon Soda Co., Ltd., Shin-Ohtemachi
Bldg. 2–1, 2–Chome Ohtemachi
Chiyoda-ku, Tokyo 100–8165, Japan.
The petition requested that 40 CFR part
180 be amended by establishing
tolerances for residues of the fungicide
ipflufenoquin, 2-[2-(7,8-difluoro-2methylquinolin-3-yloxy)-6fluorophenyl]propan-2-ol, in or on
almond at 0.10 ppm; almond hulls at 3.0
ppm; and pome fruit (Crop Group 11–
10) at 0.15 ppm; and tolerances for
residues for ipflufenoquin, QP–1–14,
QP–1–10, QP–1–11, and QP–1–15 (in
terms of ipflufenoquin) on cattle, fat at
0.010 ppm; cattle, meat at 0.01 ppm;
cattle, meat byproducts at 0.010 ppm;
dairy cattle milk at 0.01 ppm; goat, fat
at 0.010 ppm; goat, meat at 0.01 ppm;
goat, meat byproducts at 0.010 ppm;
horse, fat at 0.010 ppm; horse, meat at
0.01 ppm; horse, meat byproducts at
0.010 ppm; sheep, fat at 0.010 ppm;
VerDate Sep<11>2014

Jkt 256001
sheep, meat at 0.01 ppm; and sheep,
meat byproducts at 0.010 ppm. That
document referenced a summary of the
petition prepared by Nippon Soda Co.,
Ltd., 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
concluded that tolerances for residues of
ipflufenoquin in livestock commodities
are not needed and is establishing the
tolerances for almond, almond hulls,
and pome fruit with several minor
adjustments. 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 ipflufenoquin
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with ipflufenoquin 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
PO 00000
Frm 00042
Fmt 4700
Sfmt 4700
subgroups of consumers, including
infants and children.
The primary targets of ipflufenoquin
in rodents are teeth, the liver, thyroid,
hematological system, and intestines.
Tooth effects included discoloration,
enamel hypoplasia, dysplasia and
abrasion of the incisors. Liver effects
included changes in liver weight and
histopathological changes (increased
single cell necrosis, bile duct
hyperplasia, and hepatocellular mitotic
figures). Thyroid effects were limited to
follicular cell hypertrophy. Effects in
the hematological system included
decrease in red blood cells, hemoglobin
and hematocrits, and increases in spleen
weight, prothrombin time and
erythropoiesis of the spleen. However,
these hematological effects were
considered mild and occurred at the
same or higher doses than the tooth
effects. Intestinal findings included
black content, minimal cellular
infiltration in the lamina propria of the
colon, minimal hyperplasia epithelium
and minimal regeneration of the surface
epithelium in the colon. Intestinal and
thyroid effects occurred at the same
doses where tooth effects were observed
only in the subchronic studies in rats.
Tooth effects including discoloration,
enamel hypoplasia, dysplasia and
abrasion of the incisors were observed
throughout the ipflufenoquin database
in rodents only. The toxicology database
showed no adverse toxicological effects
were observed in dogs.
Potential signs of neurotoxicity were
observed in the acute neurotoxicity
(ACN) study, but only in one sex at the
highest doses. No changes in motor
activity were observed in a 13-week oral
study in rats. No developmental or
maternal effects were reported in the
developmental studies in rats and
rabbits. No treatment-related
reproductive effects were reported in
the reproductive toxicity study in rats.
Decreased pup body weight was
observed at the same doses where
parental toxicity was observed.
Although no immunotoxicity study is
available for ipflufenoquin, no evidence
of immunotoxicity was observed in
other submitted studies. No systemic
toxicity was observed in a dermal study
in rats up to the limit dose.
Ipflufenoquin 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 ipflufenoquin as well
as the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://

Health Risk Assessment’’) at page 37 in
docket ID number EPA–HQ–OPP–2020–
0225.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticide.
A summary of the toxicological
endpoints for ipflufenoquin used for
human risk assessment can be found in
the Ipflufenoquin Human Health Risk
Assessment.

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to ipflufenoquin, EPA
considered exposure under the
petitioned-for tolerances. EPA assessed
dietary exposures from ipflufenoquin 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.
VerDate Sep<11>2014
16:32 Feb 28, 2022
Jkt 256001
No such effects were identified in the
toxicological studies for ipflufenoquin;
therefore, a quantitative acute dietary
exposure assessment is unnecessary. An
acute dietary exposure assessment was
not required because no endpoint
attributable to a single dose was
identified in the ipflufenoquin database.
ii. Chronic exposure. In conducting
the chronic dietary exposure
assessment, EPA used the 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. EPA conducted an unrefined
chronic dietary exposure assessment
using tolerance-level residues, 100%
crop treated assumptions, the Agency’s
2018 default processing factors, and
empirical processing factors where
available.
iii. Cancer. Based on its review of
available data, EPA has concluded that
ipflufenoquin is not likely to be
carcinogenic. Therefore, a dietary
exposure assessment for the purpose of
assessing cancer risk is unnecessary.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue or PCT
information in the dietary assessment
for ipflufenoquin.
2. Dietary exposure from drinking
water. The Agency used screening-level
water exposure models in the dietary
exposure analysis and risk assessment
for ipflufenoquin in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
ipflufenoquin. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www2.epa.gov/
pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide.
Based on the Tier II Exposure Model
Pesticide in Water Calculator (PWC)
(v1.52, Feb. 23, 2016), the estimated
drinking water concentrations (EDWCs)
of ipflufenoquin for acute exposures are
estimated to be 3.71 parts per billion
(ppb) for surface water and 53.6 ppb for
ground water. For chronic exposures for
non-cancer assessments are estimated to
be 1.28 ppb for surface water and 49.1
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 49.1ppb
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-
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
11317
occupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Ipflufenoquin is not being 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
ipflufenoquin and any other substances,
and ipflufenoquin does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that ipflufenoquin has a
common mechanism of toxicity with
other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act (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.
No evidence of increased quantitative or
qualitative susceptibility was seen in rat
and rabbit developmental toxicity
studies. Decreased pup body weight was
observed in the reproduction study only
in the presence of parental toxicity.
Subchronic oral toxicity studies indicate
E:\FR\FM\01MRR1.SGM
01MRR1
11318
Federal Register / Vol. 87, No. 40 / Tuesday, March 1, 2022 / Rules and Regulations
jspears on DSK121TN23PROD with RULES1
tooth discoloration and enamel
hypoplasia in rats exposed to
ipflufenoquin. Children are considered
the most susceptible population to the
tooth effects since dental enamel
development and formation occurs
during childhood.
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
ipflufenoquin is adequate to
characterize the pre- and postnatal risk
for infants and children.
ii. There is evidence of potential
neurotoxicity (decreased motor activity)
in the ipflufenoquin database in the
ACN study. However, concern is low
because: The observed effects are well
characterized, with clear NOAELs; they
occur only at the highest doses tested;
and the PODs are based on the most
sensitive effects and are protective of
any potential neurotoxicity.
iii. In the 2-generation reproduction
study in rats, there were no
reproductive effects observed, and
offspring toxicity was observed only in
the presence of parental toxicity.
Although potential signs of
neurotoxicity were observed in the ACN
study, clear NOAELs/LOAELs are
established, and effects occurred at high
doses that are not relevant for risk
assessment purposes. Moreover,
although children are more susceptible
to the tooth effects seen in the database,
the PODs selected for risk assessment
purposes are protective of the offspring
and potential effects seen in the
database.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100 PCT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to ipflufenoquin
in drinking water. These assessments
will not underestimate the exposure and
risks posed by ipflufenoquin.
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
VerDate Sep<11>2014
16:32 Feb 28, 2022
Jkt 256001
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, ipflufenoquin 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 ipflufenoquin
from food and water will utilize less
than 1% of the cPAD for the general
U.S. population and all population
subgroups. There are no residential uses
for ipflufenoquin.
3. Short- and intermediate-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). Short- and
intermediate-term adverse effects were
identified; however, ipflufenoquin is
not being proposed to be registered for
any use patterns that would result in
either short- or intermediate-term
residential exposure. Short- and
intermediate-term risk is assessed based
on short- and intermediate-term
residential exposure plus chronic
dietary exposure. Because there is no
short- or intermediate-term residential
exposure and chronic dietary exposure
has already been assessed under the
appropriately protective cPAD (which is
at least as protective as the POD used to
assess short-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 ipflufenoquin.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
ipflufenoquin is not expected to pose a
cancer risk to humans.
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
ipflufenoquin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
The petitioner has proposed an
adequate analytical method, Method No.
P 3996 G, adapted from the multiresidue method (quick, easy, cheap,
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
effective, rugged and safe; QuEChERS;
Method No. EN 15662:2009–02) for the
determination of ipflufenoquin in plant
commodities. For livestock
commodities, adequate enforcement
methodology, Method No. NCAS 18–
290 (adapted from QuEChERS multiresidue enforcement method EN 15662),
using high-performance liquid
chromatography with tandem mass
detection (HPLC/MS–MS) is available
for determination of residues of
ipflufenoquin.
The method may be requested from:

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 has not established any
MRLs for ipflufenoquin.
C. Revisions To Petitioned-For
Tolerances
Based on the feeding study and the
dietary burden estimates, EPA
concludes that there is no reasonable
expectation of finite residues in
livestock commodities as a result of
eating treated feedstuff (40 CFR
180.6(a)(3)). Therefore, tolerances for
residues of ipflufenoquin in livestock
commodities are not needed.
Additionally, EPA corrected the pome
fruit crop group commodity definition
and is establishing the tolerance level
for ‘‘almond, hulls’’ at 3 ppm instead of
3.0 ppm to be consistent with OECD’s
rounding class practices.
Although the summary of the petition
cited in Unit II of this preamble
indicated a request for a tolerance on
almond at 0.10 ppm (and EPA’s notice
of filing published in the Federal
Register indicated the request for a
tolerance at 0.10 ppm), the actual
petition sought a tolerance at 0.01 ppm.
Based on its review of the underlying
residue data, EPA has determined that
it is appropriate to set the tolerance for
almond at 0.01 ppm.
V. Conclusion
Therefore, tolerances are established
for residues of ipflufenoquin, 2-[2-(7,8difluoro-2-methylquinolin-3-yloxy)-6-

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 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
VerDate Sep<11>2014
16:32 Feb 28, 2022
Jkt 256001
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).

This regulation establishes an
exemption from the requirement of a
tolerance for residues of potassium
acetate (CAS Reg. No. 127–08–2) when
used as an inert ingredient (nutrient) in
pesticide formulations applied to
growing crops only. Valagro S.p.A.
submitted a petition to EPA under the
Federal Food, Drug, and Cosmetic Act
(FFDCA), requesting establishment of an
exemption from the requirement of a
tolerance for potassium acetate. This
regulation eliminates the need to
establish a maximum permissible level
for residues of potassium acetate when
used in accordance with this exemption.

II. Summary of Petitioned-For Tolerance
In the Federal Register of May 29, 2020 (85 FR 32338) (FRL-10009-
84), 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
9F8801) by Nippon Soda Co., Ltd., Shin-Ohtemachi Bldg. 2-1, 2-Chome
Ohtemachi Chiyoda-ku, Tokyo 100-8165, Japan. The petition requested
that 40 CFR part 180 be amended by establishing tolerances for residues
of the fungicide ipflufenoquin, 2-[2-(7,8-difluoro-2-methylquinolin-3-
yloxy)-6-fluorophenyl]propan-2-ol, in or on almond at 0.10 ppm; almond
hulls at 3.0 ppm; and pome fruit (Crop Group 11-10) at 0.15 ppm; and
tolerances for residues for ipflufenoquin, QP-1-14, QP-1-10, QP-1-11,
and QP-1-15 (in terms of ipflufenoquin) on cattle, fat at 0.010 ppm;
cattle, meat at 0.01 ppm; cattle, meat byproducts at 0.010 ppm; dairy
cattle milk at 0.01 ppm; goat, fat at 0.010 ppm; goat, meat at 0.01
ppm; goat, meat byproducts at 0.010 ppm; horse, fat at 0.010 ppm;
horse, meat at 0.01 ppm; horse, meat byproducts at 0.010 ppm; sheep,
fat at 0.010 ppm; sheep, meat at 0.01 ppm; and sheep, meat byproducts
at 0.010 ppm. That document referenced a summary of the petition
prepared by Nippon Soda Co., Ltd., 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
concluded that tolerances for residues of ipflufenoquin in livestock
commodities are not needed and is establishing the tolerances for
almond, almond hulls, and pome fruit with several minor adjustments.
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 ipflufenoquin including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with ipflufenoquin
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 targets of ipflufenoquin in rodents are teeth, the
liver, thyroid, hematological system, and intestines. Tooth effects
included discoloration, enamel hypoplasia, dysplasia and abrasion of
the incisors. Liver effects included changes in liver weight and
histopathological changes (increased single cell necrosis, bile duct
hyperplasia, and hepatocellular mitotic figures). Thyroid effects were
limited to follicular cell hypertrophy. Effects in the hematological
system included decrease in red blood cells, hemoglobin and
hematocrits, and increases in spleen weight, prothrombin time and
erythropoiesis of the spleen. However, these hematological effects were
considered mild and occurred at the same or higher doses than the tooth
effects. Intestinal findings included black content, minimal cellular
infiltration in the lamina propria of the colon, minimal hyperplasia
epithelium and minimal regeneration of the surface epithelium in the
colon. Intestinal and thyroid effects occurred at the same doses where
tooth effects were observed only in the subchronic studies in rats.
Tooth effects including discoloration, enamel hypoplasia, dysplasia and
abrasion of the incisors were observed throughout the ipflufenoquin
database in rodents only. The toxicology database showed no adverse
toxicological effects were observed in dogs.
Potential signs of neurotoxicity were observed in the acute
neurotoxicity (ACN) study, but only in one sex at the highest doses. No
changes in motor activity were observed in a 13-week oral study in
rats. No developmental or maternal effects were reported in the
developmental studies in rats and rabbits. No treatment-related
reproductive effects were reported in the reproductive toxicity study
in rats. Decreased pup body weight was observed at the same doses where
parental toxicity was observed.
Although no immunotoxicity study is available for ipflufenoquin, no
evidence of immunotoxicity was observed in other submitted studies. No
systemic toxicity was observed in a dermal study in rats up to the
limit dose. Ipflufenoquin 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 ipflufenoquin as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in document ``Ipflufenoquin. Human Health Risk
[[Page 11317]]
Assessment for Proposed Section 3 Registration of the New Active
Ingredient for Uses on Pome Fruit (Crop Group 11-10) and Almond.''
(hereinafter ``Ipflufenoquin Human Health Risk Assessment'') at page 37
in docket ID number EPA-HQ-OPP-2020-0225.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticide.
A summary of the toxicological endpoints for ipflufenoquin used for
human risk assessment can be found in the Ipflufenoquin Human Health
Risk Assessment.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to ipflufenoquin, EPA considered exposure under the
petitioned-for tolerances. EPA assessed dietary exposures from
ipflufenoquin 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
ipflufenoquin; therefore, a quantitative acute dietary exposure
assessment is unnecessary. An acute dietary exposure assessment was not
required because no endpoint attributable to a single dose was
identified in the ipflufenoquin database.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment, EPA used the 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. EPA conducted an
unrefined chronic dietary exposure assessment using tolerance-level
residues, 100% crop treated assumptions, the Agency's 2018 default
processing factors, and empirical processing factors where available.
iii. Cancer. Based on its review of available data, EPA has
concluded that ipflufenoquin is not likely to be carcinogenic.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue or PCT information in the dietary
assessment for ipflufenoquin.
2. Dietary exposure from drinking water. The Agency used screening-
level water exposure models in the dietary exposure analysis and risk
assessment for ipflufenoquin in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of ipflufenoquin. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Tier II Exposure Model Pesticide in Water Calculator
(PWC) (v1.52, Feb. 23, 2016), the estimated drinking water
concentrations (EDWCs) of ipflufenoquin for acute exposures are
estimated to be 3.71 parts per billion (ppb) for surface water and 53.6
ppb for ground water. For chronic exposures for non-cancer assessments
are estimated to be 1.28 ppb for surface water and 49.1 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 49.1ppb 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). Ipflufenoquin is not
being 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 ipflufenoquin and any
other substances, and ipflufenoquin does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that ipflufenoquin has
a common mechanism of toxicity with other substances. For information
regarding EPA's efforts to determine which chemicals have a common
mechanism of toxicity and to evaluate the cumulative effects of such
chemicals, see EPA's website at https://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 Food Quality
Protection Act (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. No evidence of increased
quantitative or qualitative susceptibility was seen in rat and rabbit
developmental toxicity studies. Decreased pup body weight was observed
in the reproduction study only in the presence of parental toxicity.
Subchronic oral toxicity studies indicate
[[Page 11318]]
tooth discoloration and enamel hypoplasia in rats exposed to
ipflufenoquin. Children are considered the most susceptible population
to the tooth effects since dental enamel development and formation
occurs during childhood.
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 ipflufenoquin is adequate to
characterize the pre- and postnatal risk for infants and children.
ii. There is evidence of potential neurotoxicity (decreased motor
activity) in the ipflufenoquin database in the ACN study. However,
concern is low because: The observed effects are well characterized,
with clear NOAELs; they occur only at the highest doses tested; and the
PODs are based on the most sensitive effects and are protective of any
potential neurotoxicity.
iii. In the 2-generation reproduction study in rats, there were no
reproductive effects observed, and offspring toxicity was observed only
in the presence of parental toxicity. Although potential signs of
neurotoxicity were observed in the ACN study, clear NOAELs/LOAELs are
established, and effects occurred at high doses that are not relevant
for risk assessment purposes. Moreover, although children are more
susceptible to the tooth effects seen in the database, the PODs
selected for risk assessment purposes are protective of the offspring
and potential effects seen in the database.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to ipflufenoquin in drinking water. These
assessments will not underestimate the exposure and risks posed by
ipflufenoquin.
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,
ipflufenoquin 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
ipflufenoquin from food and water will utilize less than 1% of the cPAD
for the general U.S. population and all population subgroups. There are
no residential uses for ipflufenoquin.
3. Short- and intermediate-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). Short- and intermediate-term adverse effects were identified;
however, ipflufenoquin is not being proposed to be registered for any
use patterns that would result in either short- or intermediate-term
residential exposure. Short- and intermediate-term risk is assessed
based on short- and intermediate-term residential exposure plus chronic
dietary exposure. Because there is no short- or intermediate-term
residential exposure and chronic dietary exposure has already been
assessed under the appropriately protective cPAD (which is at least as
protective as the POD used to assess short-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 ipflufenoquin.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, ipflufenoquin is not expected to pose a cancer risk to humans.
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 ipflufenoquin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
The petitioner has proposed an adequate analytical method, Method
No. P 3996 G, adapted from the multi-residue method (quick, easy,
cheap, effective, rugged and safe; QuEChERS; Method No. EN 15662:2009-
02) for the determination of ipflufenoquin in plant commodities. For
livestock commodities, adequate enforcement methodology, Method No.
NCAS 18-290 (adapted from QuEChERS multi-residue enforcement method EN
15662), using high-performance liquid chromatography with tandem mass
detection (HPLC/MS-MS) is available for determination of residues of
ipflufenoquin.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
[email protected].
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4).
The Codex has not established any MRLs for ipflufenoquin.
C. Revisions To Petitioned-For Tolerances
Based on the feeding study and the dietary burden estimates, EPA
concludes that there is no reasonable expectation of finite residues in
livestock commodities as a result of eating treated feedstuff (40 CFR
180.6(a)(3)). Therefore, tolerances for residues of ipflufenoquin in
livestock commodities are not needed. Additionally, EPA corrected the
pome fruit crop group commodity definition and is establishing the
tolerance level for ``almond, hulls'' at 3 ppm instead of 3.0 ppm to be
consistent with OECD's rounding class practices.
Although the summary of the petition cited in Unit II of this
preamble indicated a request for a tolerance on almond at 0.10 ppm (and
EPA's notice of filing published in the Federal Register indicated the
request for a tolerance at 0.10 ppm), the actual petition sought a
tolerance at 0.01 ppm. Based on its review of the underlying residue
data, EPA has determined that it is appropriate to set the tolerance
for almond at 0.01 ppm.
V. Conclusion
Therefore, tolerances are established for residues of
ipflufenoquin, 2-[2-(7,8-difluoro-2-methylquinolin-3-yloxy)-6-
[[Page 11319]]
fluorophenyl]propan-2-ol, in or on almond at 0.01 ppm; almond, hulls at
3 ppm; and fruit, pome, group 11-10 at 0.15 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 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).
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).
