II. Summary of Petitioned-For
Tolerance
In the Federal Register of December
17, 2014 (79 FR 75107) (FRL–9918–90),
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 4E8241) by
Interregional Research Project Number 4
(IR–4), 500 College Road East, Suite 201
W., Princeton, NJ 08540. The petition
requested that 40 CFR part 180 be
amended by establishing tolerances for
residues of the insecticide novaluron,
(N-[[[3-chloro-4-[1,1,2-trifluoro-2(trifluoromethoxy)ethoxy]
phenyl]amino]carbonyl]-2,6-difluoro
benzamide), in or on avocado at 0.60
parts per million (ppm); carrot at 0.05
ppm; bean at 0.60 ppm; vegetable,
fruiting, group 8–10 at 1.0 ppm; fruit,
pome, group 11–10 at 2.0 ppm; cherry
subgroup 12–12A at 8.0 ppm; peach

subgroup 12–12B at 1.9 ppm; and plum
subgroup 12–12C at 1.9 ppm.
Upon approval of the petitioned-for
tolerances listed above, the petition
proposed to remove the following
established tolerances for residues of
novaluron from 40 CFR 180.598: Bean,
succulent, snap at 0.60 ppm; bean, dry,
seed at 0.30 ppm; cherry at 8.0 ppm;
fruit, pome, group 11 at 2.0 ppm; fruit,
stone, group 12, except cherry at 1.9
ppm; vegetable, fruiting, group 8 at 1.0
ppm; cocona at 1.0 ppm; African
eggplant at 1.0 ppm; pea eggplant at 1.0
ppm; scarlet eggplant at 1.0 ppm; goji
berry at 1.0 ppm; garden huckleberry at
1.0 ppm; martynia at 1.0 ppm; naranjilla
at 1.0 ppm; okra at 1.0 ppm; roselle at
1.0 ppm; sunberry at 1.0 ppm; bush
tomato at 1.0 ppm; currant tomato at 1.0
ppm; and tree tomato at 1.0 ppm. These
tolerances were requested for removal
because they will be superseded by
establishment of the petitioned-for
tolerances. That document referenced a
summary of the petition prepared on
behalf of IR–4 by Makhteshim-Agan of
North America, Inc., the registrant,
which is available in the docket,
https://www.regulations.gov. Comments
were received on the notice of filing.
EPA’s response to these comments is
discussed in Unit IV.C.
Based upon review of the data
supporting the petition, EPA has revised
several proposed tolerances. EPA has
also determined that the previously
established tolerances in or on
vegetable, cucurbit, group 9 and plum,
prune, dried should be revised. Finally,
EPA determined that establishing a
tolerance on bean is not appropriate;
rather, a tolerance should be established
on bean, succulent and the previously
established tolerance on bean, dry, seed
should not be removed. 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
VerDate Sep<11>2014
15:06 Jul 21, 2015
Jkt 235001
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 novaluron
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with novaluron 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.
In subchronic and chronic toxicity
studies, novaluron primarily produced
hematotoxic effects such as
methemoglobinemia, decreased
hemoglobin, decreased hematocrit,
decreased red blood cells (RBCs) (or
erythrocytes) and increased reticulocyte
counts that were associated with
compensatory erythropoiesis. Increased
spleen weights or hemosiderosis in the
spleen were considered to be due to
enhanced removal of damaged
erythrocytes and not to a direct
immunotoxic effect.
There was no maternal or
developmental toxicity seen in the rat
and rabbit developmental toxicity
studies up to the limit doses. In the 2generation reproductive toxicity study
in rats, both parental and offspring
toxicity (increased spleen weights) were
observed at the same dose. Reproductive
toxicity, including decreases in
epididymal sperm counts and increased
age at preputial separation in the F1
generation, was observed at a higher
dose than the increased spleen weights
and were consistent with the primary
effects in the database.
Clinical signs of neurotoxicity
(piloerection, irregular breathing),
changes in functional observational
battery (FOB) parameters (increased
head swaying, abnormal gait), and
neuropathology (sciatic and tibial nerve
degeneration) were seen in the rat acute
neurotoxicity study at the limit dose.
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
However, no signs of neurotoxicity or
neuropathology were observed in the
subchronic neurotoxicity study in rats at
similar doses or in any other subchronic
or chronic toxicity study in rats, mice,
or dogs. In the submitted
immunotoxicity study, the only sign of
potential immunotoxicity for novaluron
was a decreased anti-sheep red blood
cell (anti-SRBC) response at twice the
limit dose in female rats. There was no
evidence of carcinogenic potential in
either the rat or mouse carcinogenicity
studies, and there was also no concern
for genotoxicity or mutagenicity.
Specific information on the studies
received and the nature of the adverse
effects caused by novaluron 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://

pages 36–40 in docket ID number EPA–
HQ–OPP–2014–0232.
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

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to novaluron, EPA considered
exposure under the petitioned-for
tolerances as well as all existing
novaluron tolerances in 40 CFR 180.598.
EPA assessed dietary exposures from
novaluron 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 novaluron; therefore, a quantitative
acute dietary exposure assessment is
unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA under the National
Health and Nutrition Examination
Survey, What We Eat in America
(NHANES/WWEIA); 2003–2008. As to
residue levels in food, EPA incorporated
average field trial residues for the
VerDate Sep<11>2014
15:06 Jul 21, 2015
Jkt 235001
majority of commodities; anticipated
residues (ARs) for meat, milk, hog, and
poultry commodities; and average
percent crop treated (PCT) data for
apples, blueberries, cabbage,
cauliflower, cotton, dry beans, pears,
peppers, potatoes, strawberries, and
tomatoes. Percent crop treated for new
use (PCTn) data were incorporated for
the recently registered grain sorghum
and sweet corn uses. For the remaining
food commodities, 100 PCT was
assumed. The registered food-handling
use was also incorporated into the
dietary assessment. Empirical
processing factors were utilized for
apple juice (translated to pear and stone
fruit juice), cottonseed oil, dried plums,
´
and tomato paste and puree. Dietary
Exposure Evaluation Model (DEEM)
(ver. 7.81) default processing factors
were used for the remaining processed
commodities.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that novaluron does not pose
a cancer risk to humans. Therefore, a
dietary exposure assessment for the
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
purpose of assessing cancer risk is
unnecessary.
iv. Anticipated residue and PCT
information. Section 408(b)(2)(E) of
FFDCA authorizes EPA to use available
data and information on the anticipated
residue levels of pesticide residues in
food and the actual levels of pesticide
residues that have been measured in
food. If EPA relies on such information,
EPA must require pursuant to FFDCA
section 408(f)(1) that data be provided 5
years after the tolerance is established,
modified, or left in effect, demonstrating
that the levels in food are not above the
levels anticipated. For the present
action, EPA will issue such data call-ins
as are required by FFDCA section
408(b)(2)(E) and authorized under
FFDCA section 408(f)(1). Data will be
required to be submitted no later than
5 years from the date of issuance of
these tolerances.
Section 408(b)(2)(F) of FFDCA states
that the Agency may use data on the
actual percent of food treated for
assessing chronic dietary risk only if:
• Condition a: The data used are
reliable and provide a valid basis to
E:\FR\FM\22JYR1.SGM
22JYR1
Lhorne on DSK7TPTVN1PROD with RULES
43332
Federal Register / Vol. 80, No. 140 / Wednesday, July 22, 2015 / Rules and Regulations
show what percentage of the food
derived from such crop is likely to
contain the pesticide residue.
• Condition b: The exposure estimate
does not underestimate exposure for any
significant subpopulation group.
• Condition c: Data are available on
pesticide use and food consumption in
a particular area, the exposure estimate
does not understate exposure for the
population in such area.
In addition, the Agency must provide
for periodic evaluation of any estimates
used. To provide for the periodic
evaluation of the estimate of PCT as
required by FFDCA section 408(b)(2)(F),
EPA may require registrants to submit
data on PCT.
The Agency estimated the average
PCT for existing uses as follows:
Apple, 10%; blueberry, 1%; cabbage,
5%; cauliflower, 2.5%; cotton, 2.5%;
dry beans, 1%; pear, 15%; pepper,
2.5%; potato, 2.5%; strawberry, 35%;
and tomato, 2.5%.
In most cases, EPA uses available data
from United States Department of
Agriculture/National Agricultural
Statistics Service (USDA/NASS),
proprietary market surveys, and the
National Pesticide Use Database for the
chemical/crop combination for the most
recent 6 to 7 years. EPA uses an average
PCT for chronic dietary risk analysis.
The average PCT figure for each existing
use is derived by combining available
public and private market survey data
for that use, averaging across all
observations, and rounding to the
nearest 5%, except for those situations
in which the average PCT is less than
one. In those cases, 1% is used as the
average PCT and 2.5% is used as the
maximum PCT. EPA uses a maximum
PCT for acute dietary risk analysis. The
maximum PCT figure is the highest
observed maximum value reported
within the recent 6 years of available
public and private market survey data
for the existing use and rounded up to
the nearest multiple of 5%.
The Agency estimated the PCT for
new uses as follows: Grain sorghum,
2%; and sweet corn, 36%.
EPA estimates PCTn for novaluron
based on the PCT of the dominant
pesticide (i.e., the one with the greatest
PCT) on that site over the three most
recent years of available data.
Comparisons are only made among
pesticides of the same pesticide types
(i.e., the dominant insecticide on the use
site is selected for comparison with a
new insecticide). The PCTs included in
the analysis may be for the same
pesticide or for different pesticides
since the same or different pesticides
may dominate for each year. Typically,
EPA uses USDA/NASS as the source for
VerDate Sep<11>2014
15:06 Jul 21, 2015
Jkt 235001
raw PCT data because it is publicly
available and does not have to be
calculated from available data sources.
When a specific use site is not surveyed
by USDA/NASS, EPA uses proprietary
data and calculates the estimated PCT.
This estimated PCTn, based on the
average PCT of the market leader, is
appropriate for use in the chronic
dietary risk assessment. This method of
estimating a PCT for a new use of a
registered pesticide or a new pesticide
produces a high-end estimate that is
unlikely, in most cases, to be exceeded
during the initial five years of actual
use. The predominant factors that bear
on whether the estimated PCTn could
be exceeded are: The extent of pest
pressure on the crops in question; the
pest spectrum of the new pesticide in
comparison with the market leaders as
well as whether the market leaders are
well-established for this use; and
resistance concerns with the market
leaders.
Novaluron specifically targets
lepidopterous insects, which are not key
pests of sorghum but are key pests of
sweet corn. However, novaluron has a
relatively narrow spectrum of pest
activity when compared to the market
leader insecticides. In addition, there
are no resistance or pest pressure issues
as indicated in Section 18 Emergency
Exemption requests for use of novaluron
on sorghum or sweet corn. All
information currently available has been
considered for novaluron use on
sorghum and sweet corn, and it is the
opinion of EPA that it is unlikely that
actual PCT for novaluron will exceed
the estimated PCT for new uses during
the next five years.
The Agency believes that the three
conditions discussed in Unit III.C.1.iv.
have been met. With respect to
Condition a, PCT estimates are derived
from Federal and private market survey
data, which are reliable and have a valid
basis. The Agency is reasonably certain
that the percentage of the food treated
is not likely to be an underestimation.
As to Conditions b and c, regional
consumption information and
consumption information for significant
subpopulations is taken into account
through EPA’s computer-based model
for evaluating the exposure of
significant subpopulations including
several regional groups. Use of this
consumption information in EPA’s risk
assessment process ensures that EPA’s
exposure estimate does not understate
exposure for any significant
subpopulation group and allows the
Agency to be reasonably certain that no
regional population is exposed to
residue levels higher than those
estimated by the Agency. Other than the
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
data available through national food
consumption surveys, EPA does not
have available reliable information on
the regional consumption of food to
which novaluron may be applied in a
particular area.
2. Dietary exposure from drinking
water. The residues of concern in
drinking water for risk assessment
purposes are novaluron, the
chlorophenyl urea degradate, and the
chloroaniline degradates. The estimated
drinking water concentrations (EDWCs)
for each of these was calculated using a
molecular weight conversion and then
combined for each modeled scenario.
The degradates are assumed to have
equal toxicity to the parent. The Agency
used screening level water exposure
models in the dietary exposure analysis
and risk assessment for novaluron and
its degradates in drinking water. These
simulation models take into account
data on the physical, chemical, and fate/
transport characteristics of novaluron
and its degradates. 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), the Screening
Concentration in Ground Water (SCI–
GROW), and Pesticide Root Zone Model
Ground Water (PRZM GW) models, the
combined EDWCs of novaluron,
chlorophenyl urea, and chloroaniline
for chronic exposures are estimated to
be 16.7 ppb for surface water and 77.8
ppb for groundwater.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 77.8 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).
Novaluron is currently registered for
the following uses that could result in
residential exposures: Indoor and
outdoor crack and crevice or perimeter
applications in residential areas and
their immediate surroundings,
including homes and apartment
buildings; on modes of transportation;
and as a spot-on use for pets. EPA
assessed residential exposure using the
following assumptions:
Adult handlers were assessed for
potential short-term inhalation
exposures from mixing, loading, and
E:\FR\FM\22JYR1.SGM
22JYR1
Lhorne on DSK7TPTVN1PROD with RULES
Federal Register / Vol. 80, No. 140 / Wednesday, July 22, 2015 / Rules and Regulations
applying novaluron via manuallypressurized hand wand and from liquid
applications of novaluron to turf. Adults
were also assessed for potential shortterm post-application inhalation
exposures to novaluron from indoor
uses. For children 1 to <2 years old,
short-term post-application inhalation
and incidental oral exposures were
assessed resulting from hand-to-mouth
contact with treated residential areas,
turf, and from contact with treated pets.
There is also the potential for
intermediate-term and long-term postapplication hand-to-mouth exposures to
children 1 to <2 years old from the
registered pet spot-on use of novaluron.
Inhalation exposures are considered
negligible for this exposure scenario;
therefore, the intermediate- and longterm aggregate risk estimates do not
include inhalation exposures. For
adults, inhalation exposure is expected
to be negligible for intermediate- and
long-term durations and was not
included in the aggregate assessment.
Additionally, a dermal endpoint has not
been selected for novaluron, so dermal
exposures to adults or children were not
assessed.

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 novaluron to share
a common mechanism of toxicity with
any other substances, and novaluron
does not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that novaluron 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
VerDate Sep<11>2014
15:06 Jul 21, 2015
Jkt 235001
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.
The prenatal and postnatal toxicology
database for novaluron includes rat and
rabbit prenatal developmental toxicity
studies and a two-generation
reproduction toxicity study in rats.
There was no evidence of increased
quantitative or qualitative susceptibility
following in utero exposure to rats or
rabbits in the developmental toxicity
studies and no evidence of increased
quantitative or qualitative susceptibility
of offspring in the reproduction study.
Neither maternal nor developmental
toxicity was seen in the developmental
studies up to the limit doses (1,000 mg/
kg/day). In the 2-generation
reproductive study in rats, offspring and
parental toxicity (increased absolute and
relative spleen weights) were similar
and occurred at the same dose (74.2 mg/
kg/day). Additionally, reproductive
effects (decreases in epididymal sperm
counts and increased age at preputial
separation in the F1 generation)
occurred at a higher dose than that
which resulted in parental toxicity.
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 novaluron
is complete.
ii. Acute and subchronic rat
neurotoxicity studies were performed
for novaluron. The clinical signs of
neurotoxicity, changes in FOB
parameters, and neuropathology were
seen in the acute neurotoxicity study at
the limit dose (2,000 mg/kg/day) only
and were not reproduced at similar,
repeated doses in the subchronic
neurotoxicity study. In addition, no
evidence of neuropathology was
observed in subchronic and chronic
toxicity studies in rats, mice, or dogs.
Therefore, novaluron is not considered
a neurotoxic chemical and there is no
need for a developmental neurotoxicity
study or additional UFs to account for
neurotoxicity.

iii. There is no evidence that
novaluron results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2-generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The chronic dietary food exposure
assessment was performed using
average field trial residues, anticipated
residues for livestock commodities,
average PCT and PCTn data for some
commodities, and empirical and default
processing factors. For the remaining
food commodities, 100 PCT was
assumed. The registered food handling
use was also incorporated into the
dietary assessment. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to novaluron in
drinking water. EPA used similarly
conservative assumptions to assess
postapplication exposure of children as
well as incidental oral exposure of
toddlers. These assessments will not
underestimate the exposure and risks
posed by novaluron.
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, novaluron 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 novaluron from
food and water will utilize 73% of the
cPAD for children 1 to 2 years old, the
population group receiving the greatest
exposure.
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). Novaluron is currently
E:\FR\FM\22JYR1.SGM
22JYR1
Lhorne on DSK7TPTVN1PROD with RULES
43334
Federal Register / Vol. 80, No. 140 / Wednesday, July 22, 2015 / Rules and Regulations
registered for uses that could result in
short-term residential exposure, and the
Agency has determined that it is
appropriate to aggregate chronic
exposure through food and water with
short-term residential exposures to
novaluron.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 1,560 for adults and 350 for
children 1 to <2 years old. Because
EPA’s level of concern for novaluron is
a MOE of 100 or below, these MOEs are
not of concern.
4. Intermediate- and long-term risk.
Intermediate- and long-term aggregate
exposure takes into account
intermediate- and long-term residential
exposure plus chronic exposure to food
and water (considered to be a
background exposure level). Novaluron
is currently registered for uses that
could result in intermediate- and longterm residential exposure, and the
Agency has determined that it is
appropriate to aggregate chronic
exposure through food and water with
intermediate- and long-term residential
exposures to novaluron.
Using the exposure assumptions
described in this unit for intermediateand long-term exposures, EPA has
concluded that the combined
intermediate- and long-term food, water,
and residential exposures result in an
aggregate MOE of 530 for children 1 to
<2 years old. For adults, since there is
no dermal endpoint and inhalation
exposure is expected to be negligible,
the average dietary consumption (food
and drinking water) exposure estimate
is representative of intermediate- and
long-term aggregate risk, and results in
an MOE of 1640. Because EPA’s level of
concern for novaluron is a MOE of 100
or below, these MOEs are not of
concern.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
novaluron is not expected to pose a
cancer risk to humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to novaluron
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies,
gas chromatography/electron-capture
VerDate Sep<11>2014
15:06 Jul 21, 2015
Jkt 235001
detection (GC/ECD) and highperformance liquid chromatography/
ultraviolet (HPLC/UV), are available to
enforce the tolerance expression.
The methods 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 established MRLs for
novaluron in or on common beans (pods
and/or immature seeds) at 0.7 ppm;
pome fruit at 3 ppm; cucurbit vegetables
at 0.2 ppm; and prunes at 3.0 ppm. EPA
is establishing tolerances in or on
succulent bean at 0.70 ppm; pome fruit
crop group 11–10 at 3.0 ppm; cucurbit
vegetable crop group 9 at 0.20 ppm; and
dried prune at 3.0 ppm in order to
harmonize with Codex. The Codex has
additionally established a tolerance in
or on fruiting vegetables other than
cucurbits at 0.7 ppm and stone fruits at
7 ppm. Because EPA is recommending
a tolerance in or on fruiting vegetables
crop group 8–10 (1.0 ppm) that is higher
than Codex, EPA cannot harmonize this
tolerance. Residue data for greenhouse
tomatoes supports the 1.0 ppm tolerance
for the group 8–10 tolerance.
The data supporting the EPA petition
result in stone fruit tolerances that are
either higher (cherry subgroup 12–12A
at 8.0 ppm) or much lower (peach
subgroup 12–12B and plum subgroup
12–12C at 1.9 ppm) than the established
Codex MRL for stone fruit at 7 ppm.
EPA notes that the stone fruit tolerances
are not harmonized with associated
Codex MRLs on these commodities
because it has been determined that the
major export market for these
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
commodities is Canada. Therefore, in
order to maintain harmonization of U.S.
tolerances and Canadian MRLs for these
commodities, the EPA is establishing
these subgroup tolerances at the levels
that align with the Canadian MRLs. No
Codex MRLs have been established for
residues of novaluron in or on avocado
or carrot.
C. Response to Comments
One comment was received to the
batched Notice of Filing that provided
brief and general concerns about toxins
and potential impacts to bees, but the
commenter did not cite a specific
petition within the Notice. The Agency
has received similar comments from this
commenter on numerous previous
occasions. Refer to Federal Register 70
FR 37686 (June 30, 2005), 70 FR 1354
(January 7, 2005), 69 FR 63096–63098
(October 29, 2004) for the Agency’s
response to these objections.
D. Revisions to Petitioned-For
Tolerances
The Agency was petitioned to
establish a tolerance of novaluron in or
on plum subgroup 12–12C. As a part of
that request, the Agency reviewed the
existing tolerance on dried prune, and
determined that the tolerance should be
amended from 2.6 ppm to 3.0 ppm in
order to harmonize with Codex. Data
were also submitted and reviewed by
EPA to allow the use of novaluron in or
on greenhouse-grown cucumbers.
During review, the Agency determined
that the existing tolerance in or on
cucurbit vegetable group 9 (which
includes cucumber) should be amended
from 0.15 ppm to 0.20 ppm in order to
harmonize with Codex.
EPA was also petitioned to establish
a tolerance in or on bean at 0.60 ppm
and to remove the existing tolerance in
or on dry bean seed at 0.30 ppm upon
approval of the proposed bean
tolerance. However, the Agency
determined that separate tolerances
should be established in or on succulent
bean and dry bean seed. Therefore, this
action will not remove the existing
tolerance for the use of novaluron in or
on dry bean seed at 0.30 ppm, and the
Agency determined that a tolerance in
or on succulent bean at 0.70 ppm is
appropriate in order to harmonize with
the established Codex tolerance on
beans. Finally, EPA revised the
proposed pome fruit crop group 11–10
tolerance from 2.0 ppm to 3.0 ppm in
order to harmonize with the established
Codex MRL.
V. Conclusion
Therefore, tolerances are established
for residues of novaluron, (N-[[[3-

subgroup 12–12B at 1.9 ppm; plum
subgroup 12–12C at 1.9 ppm; and
vegetable, fruiting, group 8–10 at 1.0
ppm. This regulation additionally
revises the existing tolerances in or on
vegetable, cucurbit, group 9 from 0.15
ppm to 0.20 ppm; and plum, prune,
dried from 2.6 ppm to 3.0 ppm. Finally,
this regulation removes established
tolerances in or on bean, snap,

VI. Statutory and Executive Order
Reviews
This action establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food

retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

II. Summary of Petitioned-For Tolerance
In the Federal Register of December 17, 2014 (79 FR 75107) (FRL-
9918-90), 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
4E8241) by Interregional Research Project Number 4 (IR-4), 500 College
Road East, Suite 201 W., Princeton, NJ 08540. The petition requested
that 40 CFR part 180 be amended by establishing tolerances for residues
of the insecticide novaluron, (N-[[[3-chloro-4-[1,1,2-trifluoro-2-
(trifluoromethoxy)ethoxy]phenyl]amino]carbonyl]-2,6-difluorobenzamide),
in or on avocado at 0.60 parts per million (ppm); carrot at 0.05 ppm;
bean at 0.60 ppm; vegetable, fruiting, group 8-10 at 1.0 ppm; fruit,
pome, group 11-10 at 2.0 ppm; cherry subgroup 12-12A at 8.0 ppm; peach
[[Page 43330]]
subgroup 12-12B at 1.9 ppm; and plum subgroup 12-12C at 1.9 ppm.
Upon approval of the petitioned-for tolerances listed above, the
petition proposed to remove the following established tolerances for
residues of novaluron from 40 CFR 180.598: Bean, succulent, snap at
0.60 ppm; bean, dry, seed at 0.30 ppm; cherry at 8.0 ppm; fruit, pome,
group 11 at 2.0 ppm; fruit, stone, group 12, except cherry at 1.9 ppm;
vegetable, fruiting, group 8 at 1.0 ppm; cocona at 1.0 ppm; African
eggplant at 1.0 ppm; pea eggplant at 1.0 ppm; scarlet eggplant at 1.0
ppm; goji berry at 1.0 ppm; garden huckleberry at 1.0 ppm; martynia at
1.0 ppm; naranjilla at 1.0 ppm; okra at 1.0 ppm; roselle at 1.0 ppm;
sunberry at 1.0 ppm; bush tomato at 1.0 ppm; currant tomato at 1.0 ppm;
and tree tomato at 1.0 ppm. These tolerances were requested for removal
because they will be superseded by establishment of the petitioned-for
tolerances. That document referenced a summary of the petition prepared
on behalf of IR-4 by Makhteshim-Agan of North America, Inc., the
registrant, which is available in the docket, https://www.regulations.gov. Comments were received on the notice of filing.
EPA's response to these comments is discussed in Unit IV.C.
Based upon review of the data supporting the petition, EPA has
revised several proposed tolerances. EPA has also determined that the
previously established tolerances in or on vegetable, cucurbit, group 9
and plum, prune, dried should be revised. Finally, EPA determined that
establishing a tolerance on bean is not appropriate; rather, a
tolerance should be established on bean, succulent and the previously
established tolerance on bean, dry, seed should not be removed. 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 novaluron including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with novaluron 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.
In subchronic and chronic toxicity studies, novaluron primarily
produced hematotoxic effects such as methemoglobinemia, decreased
hemoglobin, decreased hematocrit, decreased red blood cells (RBCs) (or
erythrocytes) and increased reticulocyte counts that were associated
with compensatory erythropoiesis. Increased spleen weights or
hemosiderosis in the spleen were considered to be due to enhanced
removal of damaged erythrocytes and not to a direct immunotoxic effect.
There was no maternal or developmental toxicity seen in the rat and
rabbit developmental toxicity studies up to the limit doses. In the 2-
generation reproductive toxicity study in rats, both parental and
offspring toxicity (increased spleen weights) were observed at the same
dose. Reproductive toxicity, including decreases in epididymal sperm
counts and increased age at preputial separation in the F1 generation,
was observed at a higher dose than the increased spleen weights and
were consistent with the primary effects in the database.
Clinical signs of neurotoxicity (piloerection, irregular
breathing), changes in functional observational battery (FOB)
parameters (increased head swaying, abnormal gait), and neuropathology
(sciatic and tibial nerve degeneration) were seen in the rat acute
neurotoxicity study at the limit dose. However, no signs of
neurotoxicity or neuropathology were observed in the subchronic
neurotoxicity study in rats at similar doses or in any other subchronic
or chronic toxicity study in rats, mice, or dogs. In the submitted
immunotoxicity study, the only sign of potential immunotoxicity for
novaluron was a decreased anti-sheep red blood cell (anti-SRBC)
response at twice the limit dose in female rats. There was no evidence
of carcinogenic potential in either the rat or mouse carcinogenicity
studies, and there was also no concern for genotoxicity or
mutagenicity.
Specific information on the studies received and the nature of the
adverse effects caused by novaluron 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: ``Novaluron: Human Health Risk
Assessment for the Petition for the Establishment of Permanent
Tolerances for Residues of Novaluron in/on Avocado; Carrot; Succulent
Bean; Vegetable, Fruiting, Crop Group 8-10; Fruit, Pome, Crop Group 11-
10; Cherry Subgroup 12-12A; Peach Subgroup 12-12B; and Plum Subgroup
12-12C; and Revisions to the Label to Include Uses on Greenhouse-Grown
Cucumber'' at pages 36-40 in docket ID number EPA-HQ-OPP-2014-0232.
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

risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for novaluron used for
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to novaluron, EPA considered exposure under the petitioned-for
tolerances as well as all existing novaluron tolerances in 40 CFR
180.598. EPA assessed dietary exposures from novaluron 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 novaluron; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA under the
National Health and Nutrition Examination Survey, What We Eat in
America (NHANES/WWEIA); 2003-2008. As to residue levels in food, EPA
incorporated average field trial residues for the majority of
commodities; anticipated residues (ARs) for meat, milk, hog, and
poultry commodities; and average percent crop treated (PCT) data for
apples, blueberries, cabbage, cauliflower, cotton, dry beans, pears,
peppers, potatoes, strawberries, and tomatoes. Percent crop treated for
new use (PCTn) data were incorporated for the recently registered grain
sorghum and sweet corn uses. For the remaining food commodities, 100
PCT was assumed. The registered food-handling use was also incorporated
into the dietary assessment. Empirical processing factors were utilized
for apple juice (translated to pear and stone fruit juice), cottonseed
oil, dried plums, and tomato paste and pur[eacute]e. Dietary Exposure
Evaluation Model (DEEM) (ver. 7.81) default processing factors were
used for the remaining processed commodities.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that novaluron does not pose a cancer risk to humans.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
iv. Anticipated residue and PCT information. Section 408(b)(2)(E)
of FFDCA authorizes EPA to use available data and information on the
anticipated residue levels of pesticide residues in food and the actual
levels of pesticide residues that have been measured in food. If EPA
relies on such information, EPA must require pursuant to FFDCA section
408(f)(1) that data be provided 5 years after the tolerance is
established, modified, or left in effect, demonstrating that the levels
in food are not above the levels anticipated. For the present action,
EPA will issue such data call-ins as are required by FFDCA section
408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be
required to be submitted no later than 5 years from the date of
issuance of these tolerances.
Section 408(b)(2)(F) of FFDCA states that the Agency may use data
on the actual percent of food treated for assessing chronic dietary
risk only if:
Condition a: The data used are reliable and provide a
valid basis to
[[Page 43332]]
show what percentage of the food derived from such crop is likely to
contain the pesticide residue.
Condition b: The exposure estimate does not underestimate
exposure for any significant subpopulation group.
Condition c: Data are available on pesticide use and food
consumption in a particular area, the exposure estimate does not
understate exposure for the population in such area.
In addition, the Agency must provide for periodic evaluation of any
estimates used. To provide for the periodic evaluation of the estimate
of PCT as required by FFDCA section 408(b)(2)(F), EPA may require
registrants to submit data on PCT.
The Agency estimated the average PCT for existing uses as follows:
Apple, 10%; blueberry, 1%; cabbage, 5%; cauliflower, 2.5%; cotton,
2.5%; dry beans, 1%; pear, 15%; pepper, 2.5%; potato, 2.5%; strawberry,
35%; and tomato, 2.5%.
In most cases, EPA uses available data from United States
Department of Agriculture/National Agricultural Statistics Service
(USDA/NASS), proprietary market surveys, and the National Pesticide Use
Database for the chemical/crop combination for the most recent 6 to 7
years. EPA uses an average PCT for chronic dietary risk analysis. The
average PCT figure for each existing use is derived by combining
available public and private market survey data for that use, averaging
across all observations, and rounding to the nearest 5%, except for
those situations in which the average PCT is less than one. In those
cases, 1% is used as the average PCT and 2.5% is used as the maximum
PCT. EPA uses a maximum PCT for acute dietary risk analysis. The
maximum PCT figure is the highest observed maximum value reported
within the recent 6 years of available public and private market survey
data for the existing use and rounded up to the nearest multiple of 5%.
The Agency estimated the PCT for new uses as follows: Grain
sorghum, 2%; and sweet corn, 36%.
EPA estimates PCTn for novaluron based on the PCT of the dominant
pesticide (i.e., the one with the greatest PCT) on that site over the
three most recent years of available data. Comparisons are only made
among pesticides of the same pesticide types (i.e., the dominant
insecticide on the use site is selected for comparison with a new
insecticide). The PCTs included in the analysis may be for the same
pesticide or for different pesticides since the same or different
pesticides may dominate for each year. Typically, EPA uses USDA/NASS as
the source for raw PCT data because it is publicly available and does
not have to be calculated from available data sources. When a specific
use site is not surveyed by USDA/NASS, EPA uses proprietary data and
calculates the estimated PCT.
This estimated PCTn, based on the average PCT of the market leader,
is appropriate for use in the chronic dietary risk assessment. This
method of estimating a PCT for a new use of a registered pesticide or a
new pesticide produces a high-end estimate that is unlikely, in most
cases, to be exceeded during the initial five years of actual use. The
predominant factors that bear on whether the estimated PCTn could be
exceeded are: The extent of pest pressure on the crops in question; the
pest spectrum of the new pesticide in comparison with the market
leaders as well as whether the market leaders are well-established for
this use; and resistance concerns with the market leaders.
Novaluron specifically targets lepidopterous insects, which are not
key pests of sorghum but are key pests of sweet corn. However,
novaluron has a relatively narrow spectrum of pest activity when
compared to the market leader insecticides. In addition, there are no
resistance or pest pressure issues as indicated in Section 18 Emergency
Exemption requests for use of novaluron on sorghum or sweet corn. All
information currently available has been considered for novaluron use
on sorghum and sweet corn, and it is the opinion of EPA that it is
unlikely that actual PCT for novaluron will exceed the estimated PCT
for new uses during the next five years.
The Agency believes that the three conditions discussed in Unit
III.C.1.iv. have been met. With respect to Condition a, PCT estimates
are derived from Federal and private market survey data, which are
reliable and have a valid basis. The Agency is reasonably certain that
the percentage of the food treated is not likely to be an
underestimation. As to Conditions b and c, regional consumption
information and consumption information for significant subpopulations
is taken into account through EPA's computer-based model for evaluating
the exposure of significant subpopulations including several regional
groups. Use of this consumption information in EPA's risk assessment
process ensures that EPA's exposure estimate does not understate
exposure for any significant subpopulation group and allows the Agency
to be reasonably certain that no regional population is exposed to
residue levels higher than those estimated by the Agency. Other than
the data available through national food consumption surveys, EPA does
not have available reliable information on the regional consumption of
food to which novaluron may be applied in a particular area.
2. Dietary exposure from drinking water. The residues of concern in
drinking water for risk assessment purposes are novaluron, the
chlorophenyl urea degradate, and the chloroaniline degradates. The
estimated drinking water concentrations (EDWCs) for each of these was
calculated using a molecular weight conversion and then combined for
each modeled scenario. The degradates are assumed to have equal
toxicity to the parent. The Agency used screening level water exposure
models in the dietary exposure analysis and risk assessment for
novaluron and its degradates in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of novaluron and its degradates. 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), the Screening Concentration in Ground Water (SCI-
GROW), and Pesticide Root Zone Model Ground Water (PRZM GW) models, the
combined EDWCs of novaluron, chlorophenyl urea, and chloroaniline for
chronic exposures are estimated to be 16.7 ppb for surface water and
77.8 ppb for groundwater.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 77.8 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).
Novaluron is currently registered for the following uses that could
result in residential exposures: Indoor and outdoor crack and crevice
or perimeter applications in residential areas and their immediate
surroundings, including homes and apartment buildings; on modes of
transportation; and as a spot-on use for pets. EPA assessed residential
exposure using the following assumptions:
Adult handlers were assessed for potential short-term inhalation
exposures from mixing, loading, and
[[Page 43333]]
applying novaluron via manually-pressurized hand wand and from liquid
applications of novaluron to turf. Adults were also assessed for
potential short-term post-application inhalation exposures to novaluron
from indoor uses. For children 1 to <2 years old, short-term post-
application inhalation and incidental oral exposures were assessed
resulting from hand-to-mouth contact with treated residential areas,
turf, and from contact with treated pets. There is also the potential
for intermediate-term and long-term post-application hand-to-mouth
exposures to children 1 to <2 years old from the registered pet spot-on
use of novaluron. Inhalation exposures are considered negligible for
this exposure scenario; therefore, the intermediate- and long-term
aggregate risk estimates do not include inhalation exposures. For
adults, inhalation exposure is expected to be negligible for
intermediate- and long-term durations and was not included in the
aggregate assessment. Additionally, a dermal endpoint has not been
selected for novaluron, so dermal exposures to adults or children were
not assessed.
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 novaluron to share a common mechanism of toxicity
with any other substances, and novaluron does not appear to produce a
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that novaluron 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. The prenatal and postnatal
toxicology database for novaluron includes rat and rabbit prenatal
developmental toxicity studies and a two-generation reproduction
toxicity study in rats. There was no evidence of increased quantitative
or qualitative susceptibility following in utero exposure to rats or
rabbits in the developmental toxicity studies and no evidence of
increased quantitative or qualitative susceptibility of offspring in
the reproduction study. Neither maternal nor developmental toxicity was
seen in the developmental studies up to the limit doses (1,000 mg/kg/
day). In the 2-generation reproductive study in rats, offspring and
parental toxicity (increased absolute and relative spleen weights) were
similar and occurred at the same dose (74.2 mg/kg/day). Additionally,
reproductive effects (decreases in epididymal sperm counts and
increased age at preputial separation in the F1 generation) occurred at
a higher dose than that which resulted in parental toxicity.
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 novaluron is complete.
ii. Acute and subchronic rat neurotoxicity studies were performed
for novaluron. The clinical signs of neurotoxicity, changes in FOB
parameters, and neuropathology were seen in the acute neurotoxicity
study at the limit dose (2,000 mg/kg/day) only and were not reproduced
at similar, repeated doses in the subchronic neurotoxicity study. In
addition, no evidence of neuropathology was observed in subchronic and
chronic toxicity studies in rats, mice, or dogs. Therefore, novaluron
is not considered a neurotoxic chemical and there is no need for a
developmental neurotoxicity study or additional UFs to account for
neurotoxicity.
iii. There is no evidence that novaluron results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The chronic dietary food exposure assessment was performed
using average field trial residues, anticipated residues for livestock
commodities, average PCT and PCTn data for some commodities, and
empirical and default processing factors. For the remaining food
commodities, 100 PCT was assumed. The registered food handling use was
also incorporated into the dietary assessment. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to novaluron in drinking water. EPA used similarly
conservative assumptions to assess postapplication exposure of children
as well as incidental oral exposure of toddlers. These assessments will
not underestimate the exposure and risks posed by novaluron.
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,
novaluron 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
novaluron from food and water will utilize 73% of the cPAD for children
1 to 2 years old, the population group receiving the greatest exposure.
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). Novaluron is
currently
[[Page 43334]]
registered for uses that could result in short-term residential
exposure, and the Agency has determined that it is appropriate to
aggregate chronic exposure through food and water with short-term
residential exposures to novaluron.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 1,560 for adults
and 350 for children 1 to <2 years old. Because EPA's level of concern
for novaluron is a MOE of 100 or below, these MOEs are not of concern.
4. Intermediate- and long-term risk. Intermediate- and long-term
aggregate exposure takes into account intermediate- and long-term
residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). Novaluron is currently
registered for uses that could result in intermediate- and long-term
residential exposure, and the Agency has determined that it is
appropriate to aggregate chronic exposure through food and water with
intermediate- and long-term residential exposures to novaluron.
Using the exposure assumptions described in this unit for
intermediate- and long-term exposures, EPA has concluded that the
combined intermediate- and long-term food, water, and residential
exposures result in an aggregate MOE of 530 for children 1 to <2 years
old. For adults, since there is no dermal endpoint and inhalation
exposure is expected to be negligible, the average dietary consumption
(food and drinking water) exposure estimate is representative of
intermediate- and long-term aggregate risk, and results in an MOE of
1640. Because EPA's level of concern for novaluron is a MOE of 100 or
below, these MOEs are not of concern.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, novaluron is not expected to pose a cancer risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to novaluron residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies, gas chromatography/electron-
capture detection (GC/ECD) and high-performance liquid chromatography/
ultraviolet (HPLC/UV), are available to enforce the tolerance
expression.
The methods 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 established MRLs for novaluron in or on common beans
(pods and/or immature seeds) at 0.7 ppm; pome fruit at 3 ppm; cucurbit
vegetables at 0.2 ppm; and prunes at 3.0 ppm. EPA is establishing
tolerances in or on succulent bean at 0.70 ppm; pome fruit crop group
11-10 at 3.0 ppm; cucurbit vegetable crop group 9 at 0.20 ppm; and
dried prune at 3.0 ppm in order to harmonize with Codex. The Codex has
additionally established a tolerance in or on fruiting vegetables other
than cucurbits at 0.7 ppm and stone fruits at 7 ppm. Because EPA is
recommending a tolerance in or on fruiting vegetables crop group 8-10
(1.0 ppm) that is higher than Codex, EPA cannot harmonize this
tolerance. Residue data for greenhouse tomatoes supports the 1.0 ppm
tolerance for the group 8-10 tolerance.
The data supporting the EPA petition result in stone fruit
tolerances that are either higher (cherry subgroup 12-12A at 8.0 ppm)
or much lower (peach subgroup 12-12B and plum subgroup 12-12C at 1.9
ppm) than the established Codex MRL for stone fruit at 7 ppm. EPA notes
that the stone fruit tolerances are not harmonized with associated
Codex MRLs on these commodities because it has been determined that the
major export market for these commodities is Canada. Therefore, in
order to maintain harmonization of U.S. tolerances and Canadian MRLs
for these commodities, the EPA is establishing these subgroup
tolerances at the levels that align with the Canadian MRLs. No Codex
MRLs have been established for residues of novaluron in or on avocado
or carrot.
C. Response to Comments
One comment was received to the batched Notice of Filing that
provided brief and general concerns about toxins and potential impacts
to bees, but the commenter did not cite a specific petition within the
Notice. The Agency has received similar comments from this commenter on
numerous previous occasions. Refer to Federal Register 70 FR 37686
(June 30, 2005), 70 FR 1354 (January 7, 2005), 69 FR 63096-63098
(October 29, 2004) for the Agency's response to these objections.
D. Revisions to Petitioned-For Tolerances
The Agency was petitioned to establish a tolerance of novaluron in
or on plum subgroup 12-12C. As a part of that request, the Agency
reviewed the existing tolerance on dried prune, and determined that the
tolerance should be amended from 2.6 ppm to 3.0 ppm in order to
harmonize with Codex. Data were also submitted and reviewed by EPA to
allow the use of novaluron in or on greenhouse-grown cucumbers. During
review, the Agency determined that the existing tolerance in or on
cucurbit vegetable group 9 (which includes cucumber) should be amended
from 0.15 ppm to 0.20 ppm in order to harmonize with Codex.
EPA was also petitioned to establish a tolerance in or on bean at
0.60 ppm and to remove the existing tolerance in or on dry bean seed at
0.30 ppm upon approval of the proposed bean tolerance. However, the
Agency determined that separate tolerances should be established in or
on succulent bean and dry bean seed. Therefore, this action will not
remove the existing tolerance for the use of novaluron in or on dry
bean seed at 0.30 ppm, and the Agency determined that a tolerance in or
on succulent bean at 0.70 ppm is appropriate in order to harmonize with
the established Codex tolerance on beans. Finally, EPA revised the
proposed pome fruit crop group 11-10 tolerance from 2.0 ppm to 3.0 ppm
in order to harmonize with the established Codex MRL.
V. Conclusion
Therefore, tolerances are established for residues of novaluron,
(N-[[[3-
[[Page 43335]]
chloro-4-[1,1,2-trifluoro-2-
(trifluoromethoxy)ethoxy]phenyl]amino]carbonyl]-2,6-difluorobenzamide),
in or on avocado at 0.60 ppm; bean, succulent at 0.70 ppm; carrot at
0.05 ppm; cherry subgroup 12-12A at 8.0 ppm; fruit, pome, group 11-10
at 3.0 ppm; peach subgroup 12-12B at 1.9 ppm; plum subgroup 12-12C at
1.9 ppm; and vegetable, fruiting, group 8-10 at 1.0 ppm. This
regulation additionally revises the existing tolerances in or on
vegetable, cucurbit, group 9 from 0.15 ppm to 0.20 ppm; and plum,
prune, dried from 2.6 ppm to 3.0 ppm. Finally, this regulation removes
established tolerances in or on bean, snap, succulent; cherry; cocona;
fruit, pome, group 11; fruit, stone, group 12, except cherry; eggplant,
African; eggplant, pea; eggplant, scarlet; goji berry; huckleberry,
garden; martynia; naranjilla; okra; roselle; sunberry; tomato, bush;
tomato, currant; tomato, tree; and vegetable, fruiting, group 8.
VI. Statutory and Executive Order Reviews
This action establishes tolerances under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
