SUPPLEMENTARY INFORMATION: VA
published a proposed rule in the
Federal Register on May 26, 2011 (76
FR 30598), which, among other things,
revised 38 CFR 17.1005. These revisions
eliminated certain exclusions from
emergency care payment or
reimbursement, and defined the
payment limitations for those qualifying
for payment or reimbursement under
the law as amended by Public Law 111–
137, enacted on February 1, 2010. In the
proposed rule we stated that § 17.1005
would be amended by adding new
paragraphs (c) and (d). However, before
VA published a final rule based on that
proposed rule, on December 21, 2011
(76 FR 79071), VA published an entirely
separate final rule that added new
paragraphs (c) and (d) to § 17.1005.
Then, VA published a final rule on
April 20, 2012 (77 FR 23615), where we
acknowledged that VA had already
added new paragraphs (c) and (d) to
§ 17.1005 (in the December 21, 2011,
final rule) and, accordingly, renumbered
the proposed § 17.1005(c) as new
§ 17.1005(e). However, in the final rule
published on April 20, 2012, VA
inadvertently failed to correct a crossreference in the newly renumbered
§ 17.1005(e)(3), from (c)(2) (in the
proposed rule) to the new (e)(2) (which
should have been cited in the final rule).
This document corrects that error by
removing (c)(2) from § 17.1005(e)(3) and
adding, in its place, (e)(2).

notice of filing.
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 fenpyroximate
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with fenpyroximate follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered their
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.
Fenpyroximate was classified as
having moderate acute oral and
inhalation toxicity in rats. It exhibited
low dermal acute toxicity and was
neither a skin nor eye irritant.
Fenpyroximate was a slight to moderate
sensitizer by the maximization test
method. Subchronic and chronic oral
exposures to fenpyroximate resulted in
overall systemic toxicity (no specific
target organ/tissue was identified). The
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
most sensitive species tested was the
dog. The effects reported in the dog
included slight bradycardia, deficits in
food consumption, body weight, bodyweight gain, and an increased incidence
of emesis and diarrhea. Emaciation and
torpor (sluggish inactivity) were
reported in female dogs at lower dose
levels than males. The highest dose
tested in the dog resulted in first- and
second-degree heart block, increased
urea concentration, decreased glucose,
and altered plasma electrolyte levels
among other signs of toxicity. In
subchronic and chronic studies with
rats, the primary effect was decreased
body-weight gain in both sexes with
hematological changes (e.g., higher
counts of red blood cells) at higher
doses.
In a rat prenatal developmental
toxicity study, a fenpyroximate dose
level that marginally affected maternal
body weight and food consumption also
resulted in an increased litter incidence
of increased thoracic ribs, indicating
increased prenatal (qualitative)
susceptibility. In the rabbits, there were
no developmental effects reported at
any of the dose levels tested. In the rat
2-generation reproductive toxicity
study, there was no indication of
increased prenatal or postnatal
susceptibility; maternal toxicity
(decreased body weight) and offspring
toxicity (decreased lactational weight
gain in both generations) occurred at the
same dose. Reproductive parameters
were not affected. Acute and subchronic
neurotoxicity studies in the rat show no
evidence that fenpyroximate specifically
targets the nervous system. In the acute
neurotoxicity study, neurotoxicity signs
such as decreases in motor activity
occurred in the presence of other effects
including decreases in body weight and
food consumption, and in the absence of
neuropathology. Similar results were
noted in a delayed acute neurotoxicity
study in the hen where no effects
(neurotoxic or otherwise) were reported.
The results of the rat subchronic
neurotoxicity study did not indicate any
neurotoxicity-specific effects; deficits in
body weight and food consumption
were the main effects reported. Effects
reported in a rat immunotoxicity study
were limited to decreased body-weight
gain, indicating the fenpyroximate does
not directly target the immune system.
There is no evidence of carcinogenic
potential for fenpyroximate based on the
results of carcinogenicity studies via the
oral route in either the rats or mice
resulting in the carcinogenicity
classification of ‘‘not likely’’ to be
carcinogenic to humans. Genotoxicity
studies including mutagenicity did not

demonstrate any genotoxic potential
resulting from fenpyroximate exposure.
Specific information on the studies
received and the nature of the adverse
effects caused by fenpyroximate 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://

at Appendix A’’, p. 30 in docket ID
number EPA–HQ–OPP–2012–0716–
0003.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
A summary of the toxicological
endpoints for fenpyroximate used for
human risk assessment is discussed in
Unit III. of the final rule published in
the Federal Register of Wednesday,
December 12, 2012 (77 FR 73945) (FRL–
9360–3).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
VerDate Mar<15>2010
18:01 Jun 14, 2013
Jkt 229001
exposure to fenpyroximate, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing fenpyroximate tolerances in 40
CFR 180.566. EPA assessed dietary
exposures from fenpyroximate 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. Such effects were identified
for fenpyroximate. In estimating acute
dietary exposure, EPA used the Dietary
Exposure Evaluation Model—Food
Consumption Intake Database (DEEM–
FCID, ver. 3.16), which incorporates
consumption information from the U.S.
Department of Agriculture (USDA)
National Health and Nutrition
Examination Survey, What We Eat in
America (NHANES/WWEIA); 2003–
2008. As to residue levels in food, EPA
assumed 100 percent crop treated (PCT),
tolerance-level residues for all
commodities, DEEM (ver. 7.81) default
processing factors for all commodities
except for apple, pear, and grape juice;
grape, raisin; orange, grapefruit,
tangerine, lemon and lime juice; tomato
paste and puree; and peppermint and
spearmint oil. Chemical-specific data
were used to calculate empirical
processing factors for these
commodities.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 2003–2008 NHANES/
WWEIA. As to residue levels in food,
EPA assumed 100 PCT, tolerance-level
residues for all commodities, DEEM
(ver. 7.81) default processing factors for
all commodities except for apple, pear,
and grape juice; grape, raisin; orange,
grapefruit, tangerine, lemon and lime
juice; tomato paste and puree; and
peppermint and spearmint oil.
Chemical-specific data were used to
calculate empirical processing factors
for these commodities.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that fenpyroximate 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. EPA did not use
anticipated residue or PCT information
in the dietary assessment for
fenpyroximate. Tolerance-level residues
and/or 100 PCT were assumed for all
food commodities.
2. Dietary exposure from drinking
water. The Agency used screening-level
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
36095
water exposure models in the dietary
exposure analysis and risk assessment
for fenpyroximate in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
fenpyroximate. 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 First Index Reservoir
Screening Tool (FIRST) model, the
Screening Concentration in Ground
Water (SCI–GROW) model, and a
Provisional Cranberry Model, the
Agency calculated conservative
estimated drinking water concentrations
(EDWCs) of fenpyroximate. Tier 1,
EDWCs reflect exposure in drinking
water to the residues of fenpyroximate
and its isomer/degradate, its cis isomer
M–1, and its carboxylic acid M–3, all of
which are assumed to have similar
toxicity.
For acute exposures, EDWCs are
estimated to be 43 parts per billion
(ppb) for surface water and 0.27 ppb for
ground water.
For chronic exposures, EDWCs are
estimated to be 8.6 ppb for surface water
and 0.27 ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
acute dietary risk assessment, the water
concentration value of 43 ppb was used
to assess the contribution to drinking
water. For chronic dietary risk
assessment, the water concentration of
value 8.6 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, termiticide, and flea
and tick control on pets).
Fenpyroximate is not registered for any
specific use patterns that would result
in residential exposure.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found fenpyroximate to
share a common mechanism of toxicity
with any other substances, and
fenpyroximate does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
E:\FR\FM\17JNR1.SGM

this tolerance action, therefore, EPA has
assumed that fenpyroximate 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 evidence of increased prenatal
(qualitative) susceptibility in a rat
prenatal developmental toxicity study.
A dose level that marginally affected
maternal body weight and food
consumption also resulted in an
increased litter incidence of increased
thoracic ribs. However, concern for
prenatal and postnatal toxicity to
fenpyroximate is low because:
i. There was a clear NOAEL in the rat
prenatal developmental toxicity study;
ii. The NOAEL for this developmental
study is being used as POD for the acute
dietary risk assessment for the
population of concern-females 13–49
years old;
iii. In the rabbit, there were no
developmental effects reported at the
levels tested; and
iv. In the rat 2-generation
reproductive toxicity study, there was
no indication of increased prenatal or
postnatal susceptibility.
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 for all exposure
scenarios. That decision is based on the
following findings:
i. The toxicity database for
fenpyroximate is complete.
ii. There is no indication that
fenpyroximate is a neurotoxic chemical
and there is no need for a
VerDate Mar<15>2010
18:01 Jun 14, 2013
Jkt 229001
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is evidence that
fenpyroximate results in increased
susceptibility in utero rats or rabbits in
the prenatal developmental studies or in
young rats in the 2-generation
reproduction study. Increased
(qualitative) prenatal susceptibility was
seen following oral exposures in the rat
developmental toxicity study, but the
concern for these effects is low, for the
reasons noted in Unit III.D.2. Therefore,
a 10X FQPA safety factor is not
necessary to account for this increased
susceptibility of infants and children.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessment
utilizes tolerance-level residues
(established or recommended) and 100
PCT for all proposed/established
commodities. By using these
assumptions, the acute and chronic
exposures/risks will not be
underestimated. The dietary drinking
water assessment utilizes water
concentration values generated by
models and associated modeling
parameters, which are designed to
provide conservative, health-protective,
high-end estimates of water
concentrations that will not likely be
exceeded. There are no registered or
proposed residential uses. These
assessments will not underestimate the
exposure and risks posed by
fenpyroximate.
from food and water will utilize 15% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. There are no residential uses
for fenpyroximate.
3. Short- and intermediate-term risks.
Short-, and intermediate-term aggregate
exposure takes into account short-, and
intermediate-term residential exposure
plus chronic exposure to food and water
(considered to be a background
exposure level). Short-, and
intermediate-term adverse effects were
identified; however, fenpyroximate is
not registered for any use patterns that
would result in short-, and
intermediate-term residential exposures.
Therefore, no further assessment of
short-, and intermediate-term risks is
necessary. EPA relies on the chronic
dietary risk assessment for evaluating
short-, and intermediate-term risks for
fenpyroximate.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
fenpyroximate is not expected to pose a
cancer risk to humans.
5. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population or to infants and children
from aggregate exposure to
fenpyroximate residues.
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. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
fenpyroximate will occupy 13% of the
aPAD for females 13–49 years old and
6.2% of the aPAD for children 1–2 years
old, the population group receiving the
greatest exposure.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to fenpyroximate
Adequate enforcement methodology
(gas chromatography method with
nitrogen/phosphorus detection (GC/

enforce the tolerance expression.
Method S19 has passed an Agency
validation and has a limit of

combined residues of fenpyroximate
and M–1 in snap beans and avocados.

IV. Other Considerations
A. Analytical Enforcement Methodology
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
E:\FR\FM\17JNR1.SGM
17JNR1
36097
Federal Register / Vol. 78, No. 116 / Monday, June 17, 2013 / Rules and Regulations
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.
Codex MRLs are established for
residues of fenpyroximate per se in
grapes (fresh and dried). Harmonization
with the Codex MRLs is not possible
because the U.S. tolerance expression
includes an additional isomer and the
U.S. use pattern requires a higher
numerical value.

C. Revisions to Petitioned-For
Tolerances
As EPA explained in its latest crop
group rulemaking (77 FR 50617, August
22, 2012), EPA will attempt to conform
petitions seeking tolerances for crop
groups to the newer established crop
groups, rather than establish new
tolerances under the pre-existing 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 requested
tolerances for ‘‘Fruit, stone, group 12’’,
EPA evaluated and is establishing
tolerances for the crop group ‘‘Fruit,
stone, group 12–12.’’
Lastly, the Agency is removing the
entry for ‘‘grape’’ from the table at 40
CFR 180.566 (a)(1) since the tolerance
for ‘‘Fruit, small, vine climbing, except
fuzzy kiwifruit, subgroup 13–07F’’ at 1.0
ppm established by this action will
subsume the existing tolerance.
V. Conclusion
Therefore, tolerances are established
for residues the insecticide
fenpyroximate, including its metabolites
and degradates, in or on the
commodities Fruit, small, vine
climbing, except fuzzy kiwifruit,
subgroup 13–07F at 1.0 ppm; Fruit,
stone, group 12–12 at 2.0; and
Vegetable, tuberous and corm, subgroup
1C at 0.10 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

Jkt 229001
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 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 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
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

(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

II. Summary of Petitioned-For Tolerance
In the Federal Register of Wednesday, November 7, 2012 (77 FR
66781) (FRL-9367-5), 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 2E8072) by Interregional Research Project Number 4 (IR-4),
500 College Road East, Suite 201W, Princeton, NJ 08540. The petition
requested that 40 CFR 180.566 be amended by establishing tolerances for
residues of the insecticide fenpyroximate, (E)-1,1-dimethylethyl 4-
[[[[(1,3-dimethyl-5-phenoxy-1H-pyrazol-4-
yl)methylene]amino]oxy]methyl]benzoate and its Z-isomer, (Z)-1,1-
dimethylethyl 4-[[[[(1,3-dimethyl-5-phenoxy-1H-pyrazol-4-
yl)methylene]amino]oxy]methyl]benzoate in or on fruit, stone, group 12-
12 at 2.0 ppm; fruit, small, vine climbing, except fuzzy kiwifruit,
subgroup 13-07F at 1.0 ppm; and vegetable, tuberous and corm, subgroup
1C at 0.1 ppm. That document referenced a summary of the petition
prepared by Nichino America, Inc., 4550 New Linden Hill Rd.,
Wilmington, DE 19808, the registrant, which is available in the docket,
https://www.regulations.gov. There were no comments received in response
to the notice of filing.
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 fenpyroximate including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with fenpyroximate
follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
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.
Fenpyroximate was classified as having moderate acute oral and
inhalation toxicity in rats. It exhibited low dermal acute toxicity and
was neither a skin nor eye irritant. Fenpyroximate was a slight to
moderate sensitizer by the maximization test method. Subchronic and
chronic oral exposures to fenpyroximate resulted in overall systemic
toxicity (no specific target organ/tissue was identified). The most
sensitive species tested was the dog. The effects reported in the dog
included slight bradycardia, deficits in food consumption, body weight,
body-weight gain, and an increased incidence of emesis and diarrhea.
Emaciation and torpor (sluggish inactivity) were reported in female
dogs at lower dose levels than males. The highest dose tested in the
dog resulted in first- and second-degree heart block, increased urea
concentration, decreased glucose, and altered plasma electrolyte levels
among other signs of toxicity. In subchronic and chronic studies with
rats, the primary effect was decreased body-weight gain in both sexes
with hematological changes (e.g., higher counts of red blood cells) at
higher doses.
In a rat prenatal developmental toxicity study, a fenpyroximate
dose level that marginally affected maternal body weight and food
consumption also resulted in an increased litter incidence of increased
thoracic ribs, indicating increased prenatal (qualitative)
susceptibility. In the rabbits, there were no developmental effects
reported at any of the dose levels tested. In the rat 2-generation
reproductive toxicity study, there was no indication of increased
prenatal or postnatal susceptibility; maternal toxicity (decreased body
weight) and offspring toxicity (decreased lactational weight gain in
both generations) occurred at the same dose. Reproductive parameters
were not affected. Acute and subchronic neurotoxicity studies in the
rat show no evidence that fenpyroximate specifically targets the
nervous system. In the acute neurotoxicity study, neurotoxicity signs
such as decreases in motor activity occurred in the presence of other
effects including decreases in body weight and food consumption, and in
the absence of neuropathology. Similar results were noted in a delayed
acute neurotoxicity study in the hen where no effects (neurotoxic or
otherwise) were reported. The results of the rat subchronic
neurotoxicity study did not indicate any neurotoxicity-specific
effects; deficits in body weight and food consumption were the main
effects reported. Effects reported in a rat immunotoxicity study were
limited to decreased body-weight gain, indicating the fenpyroximate
does not directly target the immune system. There is no evidence of
carcinogenic potential for fenpyroximate based on the results of
carcinogenicity studies via the oral route in either the rats or mice
resulting in the carcinogenicity classification of ``not likely'' to be
carcinogenic to humans. Genotoxicity studies including mutagenicity did
not
[[Page 36095]]
demonstrate any genotoxic potential resulting from fenpyroximate
exposure.
Specific information on the studies received and the nature of the
adverse effects caused by fenpyroximate 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: ``Fenpyroximate. Human-Health Risk
Assessment for Proposed Section 3 Uses on Stone Fruits (Group 12-12),
Tuberous and Corm Vegetables (Subgroup 1C), and Small Vine Climbing
Fruits Except Kiwifruit (Subgroup 13-07F), dated May 8, 2013 at
Appendix A'', p. 30 in docket ID number EPA-HQ-OPP-2012-0716-0003.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for fenpyroximate used for
human risk assessment is discussed in Unit III. of the final rule
published in the Federal Register of Wednesday, December 12, 2012 (77
FR 73945) (FRL-9360-3).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fenpyroximate, EPA considered exposure under the
petitioned-for tolerances as well as all existing fenpyroximate
tolerances in 40 CFR 180.566. EPA assessed dietary exposures from
fenpyroximate 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. Such effects were identified
for fenpyroximate. In estimating acute dietary exposure, EPA used the
Dietary Exposure Evaluation Model--Food Consumption Intake Database
(DEEM-FCID, ver. 3.16), which incorporates consumption information from
the U.S. Department of Agriculture (USDA) National Health and Nutrition
Examination Survey, What We Eat in America (NHANES/WWEIA); 2003-2008.
As to residue levels in food, EPA assumed 100 percent crop treated
(PCT), tolerance-level residues for all commodities, DEEM (ver. 7.81)
default processing factors for all commodities except for apple, pear,
and grape juice; grape, raisin; orange, grapefruit, tangerine, lemon
and lime juice; tomato paste and puree; and peppermint and spearmint
oil. Chemical-specific data were used to calculate empirical processing
factors for these commodities.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 2003-2008
NHANES/WWEIA. As to residue levels in food, EPA assumed 100 PCT,
tolerance-level residues for all commodities, DEEM (ver. 7.81) default
processing factors for all commodities except for apple, pear, and
grape juice; grape, raisin; orange, grapefruit, tangerine, lemon and
lime juice; tomato paste and puree; and peppermint and spearmint oil.
Chemical-specific data were used to calculate empirical processing
factors for these commodities.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that fenpyroximate 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. EPA did not use
anticipated residue or PCT information in the dietary assessment for
fenpyroximate. 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 fenpyroximate in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of fenpyroximate. 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 First Index Reservoir Screening Tool (FIRST) model,
the Screening Concentration in Ground Water (SCI-GROW) model, and a
Provisional Cranberry Model, the Agency calculated conservative
estimated drinking water concentrations (EDWCs) of fenpyroximate. Tier
1, EDWCs reflect exposure in drinking water to the residues of
fenpyroximate and its isomer/degradate, its cis isomer M-1, and its
carboxylic acid M-3, all of which are assumed to have similar toxicity.
For acute exposures, EDWCs are estimated to be 43 parts per billion
(ppb) for surface water and 0.27 ppb for ground water.
For chronic exposures, EDWCs are estimated to be 8.6 ppb for
surface water and 0.27 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 43 ppb was used to assess
the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 8.6 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,
termiticide, and flea and tick control on pets). Fenpyroximate is not
registered for any specific use patterns that would result in
residential exposure.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found fenpyroximate to share a common mechanism of
toxicity with any other substances, and fenpyroximate does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of
[[Page 36096]]
this tolerance action, therefore, EPA has assumed that fenpyroximate
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 evidence of
increased prenatal (qualitative) susceptibility in a rat prenatal
developmental toxicity study. A dose level that marginally affected
maternal body weight and food consumption also resulted in an increased
litter incidence of increased thoracic ribs. However, concern for
prenatal and postnatal toxicity to fenpyroximate is low because:
i. There was a clear NOAEL in the rat prenatal developmental
toxicity study;
ii. The NOAEL for this developmental study is being used as POD for
the acute dietary risk assessment for the population of concern-females
13-49 years old;
iii. In the rabbit, there were no developmental effects reported at
the levels tested; and
iv. In the rat 2-generation reproductive toxicity study, there was
no indication of increased prenatal or postnatal susceptibility.
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 for all exposure scenarios. That decision is
based on the following findings:
i. The toxicity database for fenpyroximate is complete.
ii. There is no indication that fenpyroximate is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is evidence that fenpyroximate results in increased
susceptibility in utero rats or rabbits in the prenatal developmental
studies or in young rats in the 2-generation reproduction study.
Increased (qualitative) prenatal susceptibility was seen following oral
exposures in the rat developmental toxicity study, but the concern for
these effects is low, for the reasons noted in Unit III.D.2. Therefore,
a 10X FQPA safety factor is not necessary to account for this increased
susceptibility of infants and children.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessment utilizes tolerance-
level residues (established or recommended) and 100 PCT for all
proposed/established commodities. By using these assumptions, the acute
and chronic exposures/risks will not be underestimated. The dietary
drinking water assessment utilizes water concentration values generated
by models and associated modeling parameters, which are designed to
provide conservative, health-protective, high-end estimates of water
concentrations that will not likely be exceeded. There are no
registered or proposed residential uses. These assessments will not
underestimate the exposure and risks posed by fenpyroximate.
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. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to fenpyroximate will occupy 13% of the aPAD for females 13-49 years
old and 6.2% of the aPAD for children 1-2 years old, the population
group receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
fenpyroximate from food and water will utilize 15% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure. There are no residential uses for fenpyroximate.
3. Short- and intermediate-term risks. Short-, and intermediate-
term aggregate exposure takes into account short-, and intermediate-
term residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). Short-, and
intermediate-term adverse effects were identified; however,
fenpyroximate is not registered for any use patterns that would result
in short-, and intermediate-term residential exposures. Therefore, no
further assessment of short-, and intermediate-term risks is necessary.
EPA relies on the chronic dietary risk assessment for evaluating short-
, and intermediate-term risks for fenpyroximate.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, fenpyroximate is not expected to pose a cancer risk to humans.
5. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population or to infants and children from aggregate
exposure to fenpyroximate residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography method with
nitrogen/phosphorus detection (GC/NPD), Method S19) is available to
enforce the tolerance expression. Method S19 has passed an Agency
validation and has a limit of quantitation (LOQ) of 0.05 ppm for the
combined residues of fenpyroximate and M-1 in snap beans and avocados.
A data-gathering liquid chromatography/mass spectroscopy/mass
spectroscopy (LC/MS/MS) method is also available.
These 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
[[Page 36097]]
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.
Codex MRLs are established for residues of fenpyroximate per se in
grapes (fresh and dried). Harmonization with the Codex MRLs is not
possible because the U.S. tolerance expression includes an additional
isomer and the U.S. use pattern requires a higher numerical value.
C. Revisions to Petitioned-For Tolerances
As EPA explained in its latest crop group rulemaking (77 FR 50617,
August 22, 2012), EPA will attempt to conform petitions seeking
tolerances for crop groups to the newer established crop groups, rather
than establish new tolerances under the pre-existing 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 requested tolerances for
``Fruit, stone, group 12'', EPA evaluated and is establishing
tolerances for the crop group ``Fruit, stone, group 12-12.''
Lastly, the Agency is removing the entry for ``grape'' from the
table at 40 CFR 180.566 (a)(1) since the tolerance for ``Fruit, small,
vine climbing, except fuzzy kiwifruit, subgroup 13-07F'' at 1.0 ppm
established by this action will subsume the existing tolerance.
V. Conclusion
Therefore, tolerances are established for residues the insecticide
fenpyroximate, including its metabolites and degradates, in or on the
commodities Fruit, small, vine climbing, except fuzzy kiwifruit,
subgroup 13-07F at 1.0 ppm; Fruit, stone, group 12-12 at 2.0; and
Vegetable, tuberous and corm, subgroup 1C at 0.10 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 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 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 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).
