II. Summary of Petitioned-For
Tolerance
In the Federal Register of May 23,
2012 (77 FR 30481) (FRL–9347–8), 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 2F7973) by BASF
Corporation, P.O. Box 13528, Research
Triangle Park, NC 27709. The petition
requested that 40 CFR part 180 be

amended by establishing tolerances for
residues of the insecticide cyflumetofen
(2-methoxyethyl a-cyano-a-[4-(1,1dimethylethyl)phenyl]-b-oxo-2(trifluoromethyl)benzenepropanoate), in
or on almond, hulls at 4.0 parts per
million (ppm); citrus, oil at 16 ppm;
fruit, citrus, group 10 at 0.3 ppm; fruit,
pome, group 11 at 0.3 ppm; grape at 0.6
ppm; grape, raisin at 0.9 ppm; nut, tree,
group 14 at 0.01 ppm; strawberry at 0.6
ppm; and tomato at 0.2 ppm. That
document referenced a summary of the
petition prepared by BASF Corporation,
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 modified
some of the tolerance levels and
commodity names requested by the
applicant. The reasons for these changes
are explained in Unit IV.D.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . . ’’
Consistent with FFDCA section
408(b)(2)(D), and the factors specified in
FFDCA section 408(b)(2)(D), EPA has
reviewed the available scientific data
and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure for including
exposure resulting from the tolerances
established by this action. EPA’s
assessment of exposures and risks

Jkt 232001
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 major target
organ in rats, mice, and dogs following
short-term and long-term oral
administration of cyflumetofen is the
adrenal glands characterized by
increased organ weight and
histopathology (vacuolation and
hypertrophy of the adrenal cortical
cells).
Cyflumetofen has low acute toxicity
by oral, dermal, and inhalation routes of
exposure. It is minimally irritating to
the eyes but not to the skin. It is a skin
sensitizer.
Decreased serum hormone
concentrations (FSH, progesterone, and
17 b-estradiol) were observed in the
mid- and high-dose F1 females in a rat
reproduction study while no hormonal
effect was observed in the F1 male rats
at any dose level. However, there were
no corresponding changes in
reproductive performance at any dose
level. In the developmental toxicity
study in rats, an increased incidence of
wavy ribs was noted at the high-dose
(1,000 milligrams/kilogram/day (mg/kg/
day)), while an increased incidence of
incompletely ossified sternal centra was
observed at the mid- and high-dose
levels. These incidences occurred in the
presence of maternal toxicity. In the
developmental toxicity study in rabbits,
a downward flexion of the forepaws
and/or hind paws was observed in the
high-dose (1,000 mg/kg/day) group pups
and delays in skeletal ossification were
observed in pups at the mid- and highdoses. Maternal toxicity (adrenal effects)
was also observed at the mid- and highdoses.
No evidence of neurotoxicity or
immunotoxicity was observed in any of
the submitted studies for cyflumetofen.
Although there is some evidence of
thyroid tumors in rats, the Agency has
determined that quantification of risk
using a non-linear approach (i.e.,
reference dose (RfD)) will adequately
account for all chronic toxicity,
including carcinogenicity, that could
result from exposure to cyflumetofen.
This conclusion is based on the
following reasons. The single tumor
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
type (thyroid c-cell) occurred in only
one sex (male) and one species (rat).
This tumor effect was seen only at high
doses (250 mg/kg/day), which far
exceeds the chronic no-observedadverse-effect-level (NOAEL) the
Agency is using for its risk assessment
(16.5 mg/kg/day). And there is no
concern for mutagenicity.
Specific information on the studies
received and the nature of the adverse
effects caused by cyflumetofen as well
as the NOAEL and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://
www.regulations.gov in document

Human Health Risk Assessment to
Support Uses on Citrus (Crop Group 10–

Tree Nuts (Crop Group 14–12), Grape,
Strawberry, and Tomato’’ section IV, pg.
12 in docket ID number EPA–HQ–OPP–
2012–0269.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which the NOAEL and the
LOAEL are identified. Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
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://www.epa.gov/
pesticides/factsheets/riskassess.htm.

endpoints for Cyflumetofen used for
human risk assessment is shown in the

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to cyflumetofen, EPA
considered exposure under the
petitioned-for tolerances in 40 CFR 180.
EPA assessed dietary exposures from
cyflumetofen 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 cyflumetofen; therefore, a
quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure
assessment, EPA used the food
consumption data from the USDA 2003–
2008 food consumption data from the
U.S. Department of Agriculture’s
(USDA’s) National Health and Nutrition
Examination Survey, What We Eat in
America, (NHANES/WWEIA). The
partially refined chronic analysis
conducted was based on tolerance-level
residues, 100% percent crop treated
(PCT) assumptions, and both
VerDate Mar<15>2010
16:26 May 20, 2014
Jkt 232001
empirically derived and default
processing factors.
iii. Cancer. Based on the data
summarized in Unit III.A., the Agency
has determined that quantification of
risk using a nonlinear approach (i.e.,
RfD) would adequately account for all
chronic toxicity, including
carcinogenicity, that could result from
exposure to cyflumetofen. Therefore, a
separate cancer dietary exposure
analysis was not performed.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue and/or PCT
information in the dietary assessment
for cyflumetofen. 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 cyflumetofen in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
cyflumetofen. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www.epa.gov/
oppefed1/models/water/index.htm.

Based on the Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening
Concentrations in Ground Water Model
as well as Pesticide Root Zone Model—
Groundwater, the estimated drinking
water concentrations (EDWCs) of
cyflumetofen for chronic exposure
assessments are estimated to be 0.33
parts per billion (ppb) for surface water
and 0.0024 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 0.33 ppb
was used to assess the contribution to
drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets). EPA
assessed residential exposure using the
following assumptions: The use of
cyflumetofen on ornamentals in
residential landscapes may result in
residential handler exposure.
Residential handler exposure is
expected to be short-term in duration as
E:\FR\FM\21MYR1.SGM
21MYR1
emcdonald on DSK67QTVN1PROD with RULES
29106
Federal Register / Vol. 79, No. 98 / Wednesday, May 21, 2014 / Rules and Regulations
intermediate- or long-term exposures are
not likely because of the intermittent
nature of applications by homeowners.
The quantitative exposure/risk
assessment developed for residential
handlers is based on the following
scenarios:
• Mixing/loading/applying liquid to
ornamentals with hose-end sprayer.
• Mixing/loading/applying liquid to
ornamentals with manually-pressurized
handwand.
• Mixing/loading/applying liquid to
ornamentals with backpack.
• Mixing/loading/applying liquid to
ornamentals with a sprinkler can.
Since no dermal hazard was
identified for cyflumetofen in the
toxicological database, only inhalation
exposure assessments were conducted
for residential handlers. EPA did not
assess post-application exposure from
the use of cyflumetofen in residential
settings because:
1. No dermal hazard was identified in
the toxicity database for cyflumetofen,
so a quantitative residential postapplication dermal risk assessment is
not required;
2. Post-application inhalation
exposure while performing activities in
previously treated gardens was not
assessed due to the low vapor pressure
and the expected dilution in outdoor air
after an application has occurred;
3. The potential for post-application
non-dietary ingestion exposure for
children (1 < 2 years old) is greatly
diminished since young children are not
expected to engage in the types of
activities associated with these areas
(e.g., gardening) or utilize these areas for
prolonged periods of play.
Further information regarding EPA
standard assumptions and generic
inputs for residential exposures may be
found at https://www.epa.gov/pesticides/
trac/science/trac6a05.pdf.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found cyflumetofen to
share a common mechanism of toxicity
with any other substances, and
cyflumetofen does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that cyflumetofen does not
have a common mechanism of toxicity
with other substances. For information

mechanism of toxicity and to evaluate

chemicals, see EPA’s Web site at
https://www.epa.gov/pesticides/
cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
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
qualitative or quantitative susceptibility
in the rat 2-generation reproduction
study; however, the rat and rabbit
developmental studies indicate
susceptibility in the pups. There is
evidence of increased quantitative
susceptibility in the rabbit
developmental toxicity study, since
developmental effects (changes in
ossicification, paw flexion, and
decreased fetal body weights) at the
limit dose were observed where no
maternal toxicity was present. There is
evidence of increased qualitative
susceptibility in the rat developmental
toxicity study as developmental effects
(increased incidence of incompletely
ossified sternal centra) were seen at the
same dose that caused an increase in
adrenal weights and organ-to-body
weight ratio in the maternal animals.
Notwithstanding, the degree of concern
for these effects in infants and children
is low because the rat and rabbit
developmental effects have clearly
defined NOAEL/LOAELs and the dose
selected for chronic risk assessment is
protective of these effects. Therefore, the
PODs based on adrenal effects in rat are
health protective of all lifestages.
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
cyflumetofen is complete.
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
ii. There is no indication that
cyflumetofen is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is some evidence that
cyflumetofen results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies.
However, as described in Unit III.D.2.,
because of the low degree of concern for
these effects, it is not necessary to retain
the 10X FQPA factor to adequately
protect infants and children.
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 cyflumetofen
in drinking water. These assessments
will not underestimate the exposure and
risks posed by cyflumetofen.
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, cyflumetofen 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 cyflumetofen
from food and water will utilize 2.3% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. Based on the explanation in
Unit III.C.3., regarding residential use
patterns, chronic residential exposure to
residues of cyflumetofen is not
expected.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water

(considered to be a background
exposure level).
Cyflumetofen is currently proposed
for uses that could result in short-term
residential exposure, and the Agency
has determined that it is appropriate to
aggregate chronic exposure through food
and water with short-term residential
exposures to cyflumetofen.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures are above the
Level of Concern (LOC) of 100 and are
not of concern (MOEs ≥ 100).
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Because no intermediate-term adverse
effect was identified, cyflumetofen is
not expected to pose an intermediateterm risk.
5. Aggregate cancer risk for U.S.
population. Based on the data
summarized in Unit III.A., EPA has
concluded that the cPAD is protective of
potential cancer effects. Given the
results of the chronic risk assessment,
cyflumetofen is not expected to pose a
cancer risk.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to cyflumetofen
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(high performance liquid
chromatography) is available to enforce
the tolerance expression.
The method may be requested from:
Chief, Analytical Chemistry Branch,
Environmental Science Center, 701

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
VerDate Mar<15>2010

Jkt 232001
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has not established a MRL
for cyflumetofen.
C. Revisions to Petitioned-For
Tolerances
EPA revised the commodity names for
the requested tolerances consistent with
its policy to establish crop group
tolerances using the most recently
established crop groups. This policy
was explained in the most recent
rulemaking establishing crop groups in
the Federal Register on August 22, 2012
(77 FR 50617) (FRL–9354–3). Under this
policy, rather than establish new
tolerances under the pre-existing crop
groups, EPA intends to conform
petitions seeking tolerances for crop
groups to the newer established crop
groups, as part of its effort to eventually
convert tolerances for any pre-existing
crop group to tolerances with coverage
under the revised crop group. Therefore,
although the petitioner had requested
tolerances on fruit, citrus, group 10;
fruit, pome, group 11; and nut, tree,
group 14. EPA evaluated and is
establishing tolerances for fruit, citrus,
group 10–10; fruit, pome, group 11–10;
and nut, tree, group 14–12, respectively.
The petitioner requested a tolerance
of 0.2 ppm for tomato based on residues
found in tomatoes that had been frozen
and stored in accordance with OECD
Guideline 506 (October 16, 2007) to
account for residue loss that may have
occurred during storage. EPA is
establishing a tolerance for tomato at
0.40 ppm. In addition, EPA is not
establishing a separate tolerance for
grape, raisin of 0.9 ppm, as requested,
since the tolerance for the raw
agricultural commodity grape at 0.60
ppm is adequate to account for any
residue concentration shown in the
processed commodity.
V. Conclusion
Therefore, tolerances are established
for residues of cyflumetofen, in or on
almond, hulls at 4.0 ppm; citrus, oil at
16 ppm; grape at 0.60 ppm; fruit, citrus,
group 10–10 at 0.30 ppm; fruit, pome,
group 11–10 at 0.30 ppm; nut, tree,
group 14–12 at 0.01 ppm; strawberry at
0.60 ppm; and tomato at 0.40 ppm.

VI. Statutory and Executive Order
Reviews
This final rule 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 final rule
has been exempted from review under
Executive Order 12866, this final rule 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 final rule 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 final rule 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 final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate

II. Summary of Petitioned-For Tolerance
In the Federal Register of May 23, 2012 (77 FR 30481) (FRL-9347-8),
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 2F7973)
by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 27709.
The petition requested that 40 CFR part 180 be
[[Page 29104]]
amended by establishing tolerances for residues of the insecticide
cyflumetofen (2-methoxyethyl [alpha]-cyano-[alpha]-[4-(1,1-
dimethylethyl)phenyl]-[beta]-oxo-2-(trifluoromethyl)benzenepropanoate),
in or on almond, hulls at 4.0 parts per million (ppm); citrus, oil at
16 ppm; fruit, citrus, group 10 at 0.3 ppm; fruit, pome, group 11 at
0.3 ppm; grape at 0.6 ppm; grape, raisin at 0.9 ppm; nut, tree, group
14 at 0.01 ppm; strawberry at 0.6 ppm; and tomato at 0.2 ppm. That
document referenced a summary of the petition prepared by BASF
Corporation, 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 modified
some of the tolerance levels and commodity names requested by the
applicant. The reasons for these changes are explained in Unit IV.D.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
. ''
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for including exposure resulting
from the tolerances established by this action. EPA's assessment of
exposures and risks associated with 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 major target organ in rats, mice, and dogs following
short-term and long-term oral administration of cyflumetofen is the
adrenal glands characterized by increased organ weight and
histopathology (vacuolation and hypertrophy of the adrenal cortical
cells).
Cyflumetofen has low acute toxicity by oral, dermal, and inhalation
routes of exposure. It is minimally irritating to the eyes but not to
the skin. It is a skin sensitizer.
Decreased serum hormone concentrations (FSH, progesterone, and 17
[beta]-estradiol) were observed in the mid- and high-dose F1
females in a rat reproduction study while no hormonal effect was
observed in the F1 male rats at any dose level. However,
there were no corresponding changes in reproductive performance at any
dose level. In the developmental toxicity study in rats, an increased
incidence of wavy ribs was noted at the high-dose (1,000 milligrams/
kilogram/day (mg/kg/day)), while an increased incidence of incompletely
ossified sternal centra was observed at the mid- and high-dose levels.
These incidences occurred in the presence of maternal toxicity. In the
developmental toxicity study in rabbits, a downward flexion of the
forepaws and/or hind paws was observed in the high-dose (1,000 mg/kg/
day) group pups and delays in skeletal ossification were observed in
pups at the mid- and high-doses. Maternal toxicity (adrenal effects)
was also observed at the mid- and high- doses.
No evidence of neurotoxicity or immunotoxicity was observed in any
of the submitted studies for cyflumetofen.
Although there is some evidence of thyroid tumors in rats, the
Agency has determined that quantification of risk using a non-linear
approach (i.e., reference dose (RfD)) will adequately account for all
chronic toxicity, including carcinogenicity, that could result from
exposure to cyflumetofen. This conclusion is based on the following
reasons. The single tumor type (thyroid c-cell) occurred in only one
sex (male) and one species (rat). This tumor effect was seen only at
high doses (250 mg/kg/day), which far exceeds the chronic no-observed-
adverse-effect-level (NOAEL) the Agency is using for its risk
assessment (16.5 mg/kg/day). And there is no concern for mutagenicity.
Specific information on the studies received and the nature of the
adverse effects caused by cyflumetofen as well as the NOAEL and the
lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies
can be found at https://www.regulations.gov in document ``Cyflumetofen:
New Active Ingredient Human Health Risk Assessment to Support Uses on
Citrus (Crop Group 10-10), Pome Fruits Crop Group 11-10), Tree Nuts
(Crop Group 14-12), Grape, Strawberry, and Tomato'' section IV, pg. 12
in docket ID number EPA-HQ-OPP-2012-0269.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which the NOAEL and the LOAEL are identified.
Uncertainty/safety factors are used in conjunction with the POD to
calculate a safe exposure level--generally referred to as a population-
adjusted dose (PAD) or a 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://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for Cyflumetofen used for
human risk assessment is shown in the following Table 1 of this unit.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to cyflumetofen, EPA considered exposure under the petitioned-
for tolerances in 40 CFR 180. EPA assessed dietary exposures from
cyflumetofen 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 cyflumetofen; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment, EPA used the food consumption data from the USDA 2003-2008
food consumption data from the U.S. Department of Agriculture's
(USDA's) National Health and Nutrition Examination Survey, What We Eat
in America, (NHANES/WWEIA). The partially refined chronic analysis
conducted was based on tolerance-level residues, 100% percent crop
treated (PCT) assumptions, and both empirically derived and default
processing factors.
iii. Cancer. Based on the data summarized in Unit III.A., the
Agency has determined that quantification of risk using a nonlinear
approach (i.e., RfD) would adequately account for all chronic toxicity,
including carcinogenicity, that could result from exposure to
cyflumetofen. Therefore, a separate cancer dietary exposure analysis
was not performed.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue and/or PCT information in the
dietary assessment for cyflumetofen. 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 cyflumetofen in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of cyflumetofen. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentrations in Ground Water Model
as well as Pesticide Root Zone Model--Groundwater, the estimated
drinking water concentrations (EDWCs) of cyflumetofen for chronic
exposure assessments are estimated to be 0.33 parts per billion (ppb)
for surface water and 0.0024 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 0.33 ppb was used to
assess the contribution to drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets). EPA assessed
residential exposure using the following assumptions: The use of
cyflumetofen on ornamentals in residential landscapes may result in
residential handler exposure. Residential handler exposure is expected
to be short-term in duration as
[[Page 29106]]
intermediate- or long-term exposures are not likely because of the
intermittent nature of applications by homeowners. The quantitative
exposure/risk assessment developed for residential handlers is based on
the following scenarios:
Mixing/loading/applying liquid to ornamentals with hose-
end sprayer.
Mixing/loading/applying liquid to ornamentals with
manually-pressurized handwand.
Mixing/loading/applying liquid to ornamentals with
backpack.
Mixing/loading/applying liquid to ornamentals with a
sprinkler can.
Since no dermal hazard was identified for cyflumetofen in the
toxicological database, only inhalation exposure assessments were
conducted for residential handlers. EPA did not assess post-application
exposure from the use of cyflumetofen in residential settings because:
1. No dermal hazard was identified in the toxicity database for
cyflumetofen, so a quantitative residential post-application dermal
risk assessment is not required;
2. Post-application inhalation exposure while performing activities
in previously treated gardens was not assessed due to the low vapor
pressure and the expected dilution in outdoor air after an application
has occurred;
3. The potential for post-application non-dietary ingestion
exposure for children (1 < 2 years old) is greatly diminished since
young children are not expected to engage in the types of activities
associated with these areas (e.g., gardening) or utilize these areas
for prolonged periods of play.
Further information regarding EPA standard assumptions and generic
inputs for residential exposures may be found at https://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found cyflumetofen to share a common mechanism of
toxicity with any other substances, and cyflumetofen does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
cyflumetofen does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the 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 qualitative or quantitative susceptibility in the rat 2-
generation reproduction study; however, the rat and rabbit
developmental studies indicate susceptibility in the pups. There is
evidence of increased quantitative susceptibility in the rabbit
developmental toxicity study, since developmental effects (changes in
ossicification, paw flexion, and decreased fetal body weights) at the
limit dose were observed where no maternal toxicity was present. There
is evidence of increased qualitative susceptibility in the rat
developmental toxicity study as developmental effects (increased
incidence of incompletely ossified sternal centra) were seen at the
same dose that caused an increase in adrenal weights and organ-to-body
weight ratio in the maternal animals. Notwithstanding, the degree of
concern for these effects in infants and children is low because the
rat and rabbit developmental effects have clearly defined NOAEL/LOAELs
and the dose selected for chronic risk assessment is protective of
these effects. Therefore, the PODs based on adrenal effects in rat are
health protective of all lifestages.
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 cyflumetofen is complete.
ii. There is no indication that cyflumetofen is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is some evidence that cyflumetofen results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies. However, as described in Unit III.D.2., because
of the low degree of concern for these effects, it is not necessary to
retain the 10X FQPA factor to adequately protect infants and children.
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 cyflumetofen in drinking water. These assessments
will not underestimate the exposure and risks posed by cyflumetofen.
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,
cyflumetofen 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
cyflumetofen from food and water will utilize 2.3% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure. Based on the explanation in Unit III.C.3., regarding
residential use patterns, chronic residential exposure to residues of
cyflumetofen is not expected.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water
[[Page 29107]]
(considered to be a background exposure level).
Cyflumetofen is currently proposed for uses that could result in
short-term residential exposure, and the Agency has determined that it
is appropriate to aggregate chronic exposure through food and water
with short-term residential exposures to cyflumetofen.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures are above the Level of Concern (LOC) of 100
and are not of concern (MOEs >= 100).
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Because no intermediate-term adverse effect was identified,
cyflumetofen is not expected to pose an intermediate-term risk.
5. Aggregate cancer risk for U.S. population. Based on the data
summarized in Unit III.A., EPA has concluded that the cPAD is
protective of potential cancer effects. Given the results of the
chronic risk assessment, cyflumetofen is not expected to pose a cancer
risk.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to cyflumetofen residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (high performance liquid
chromatography) is available to enforce the tolerance expression.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for cyflumetofen.
C. Revisions to Petitioned-For Tolerances
EPA revised the commodity names for the requested tolerances
consistent with its policy to establish crop group tolerances using the
most recently established crop groups. This policy was explained in the
most recent rulemaking establishing crop groups in the Federal Register
on August 22, 2012 (77 FR 50617) (FRL-9354-3). Under this policy,
rather than establish new tolerances under the pre-existing crop
groups, EPA intends to conform petitions seeking tolerances for crop
groups to the newer established crop groups, as part of its effort to
eventually convert tolerances for any pre-existing crop group to
tolerances with coverage under the revised crop group. Therefore,
although the petitioner had requested tolerances on fruit, citrus,
group 10; fruit, pome, group 11; and nut, tree, group 14. EPA evaluated
and is establishing tolerances for fruit, citrus, group 10-10; fruit,
pome, group 11-10; and nut, tree, group 14-12, respectively.
The petitioner requested a tolerance of 0.2 ppm for tomato based on
residues found in tomatoes that had been frozen and stored in
accordance with OECD Guideline 506 (October 16, 2007) to account for
residue loss that may have occurred during storage. EPA is establishing
a tolerance for tomato at 0.40 ppm. In addition, EPA is not
establishing a separate tolerance for grape, raisin of 0.9 ppm, as
requested, since the tolerance for the raw agricultural commodity grape
at 0.60 ppm is adequate to account for any residue concentration shown
in the processed commodity.
V. Conclusion
Therefore, tolerances are established for residues of cyflumetofen,
in or on almond, hulls at 4.0 ppm; citrus, oil at 16 ppm; grape at 0.60
ppm; fruit, citrus, group 10-10 at 0.30 ppm; fruit, pome, group 11-10
at 0.30 ppm; nut, tree, group 14-12 at 0.01 ppm; strawberry at 0.60
ppm; and tomato at 0.40 ppm.
VI. Statutory and Executive Order Reviews
This final rule 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 final rule has
been exempted from review under Executive Order 12866, this final rule
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 final rule 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 final rule 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 final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate
[[Page 29108]]
as described under Title II of the Unfunded Mandates Reform Act of 1995
(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 of 1995 (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).
