potential. As noted in this Unit there are
no chronic risks of concern.
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 hexythiazox
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
The existing enforcement method
(high performance liquid
chromatography using ultraviolet
detection (HPLC/UV)) published in the
Pesticide Analytical Manual (PAM) II is
adequate to enforce the tolerance
expression. The method may be
requested from: Chief, Analytical
Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
There are no Codex, Canadian or
Mexican MRLs (maximum residue
levels) for residues of hexythiazox on
potatoes.
erowe on DSK5CLS3C1PROD with RULES
V. Conclusion
Therefore, a tolerance is established
for combined residues of hexythiazox,
(trans-5-(4-chlorophenyl)-N-cyclohexyl4-methyl-2-oxothiazolidine-3carboxamide) and its metabolites
containing the (4-chlorophenyl)-4methyl-2-oxo-3-thiazolidine moiety, in
or on potato at 0.02 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA 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
VerDate Nov<24>2008
12:48 Dec 01, 2009
Jkt 220001
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 section 408(d) of FFDCA, 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 section 408(n)(4) of FFDCA. 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) (Public Law 104–4).
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), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
VII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. 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 this final rule in the
Federal Register. This final rule is not
a ‘‘major rule’’ as defined by 5 U.S.C.
804(2).

amended by establishing tolerances for
combined residues of the insecticide
fenpyroximate, (E)-1,1-dimethylethyl 4[[[[(1,3-dimethyl-5-phenoxy-1H-pyrazol4-yl)methylene]amino]oxy]methyl]

Nichino America, Inc., the registrant,
which is available to the public 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 section 408(b)(2)(D)
of FFDCA, and the factors specified in
section 408(b)(2)(D) of FFDCA, 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 the petitioned-for
tolerance for combined residues of
fenpyroximate and its Z-isomer in or on
berry, low growing, subgroup 13–07G, at
1.0 ppm. EPA’s assessment of exposures
and risks associated with establishing
tolerances follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its validity,
E:\FR\FM\02DER1.SGM
02DER1
erowe on DSK5CLS3C1PROD with RULES
63076
Federal Register / Vol. 74, No. 230 / Wednesday, December 2, 2009 / Rules and Regulations
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 has moderate oral and
inhalation toxicity. It has low dermal
toxicity and is not an eye or skin
irritant. Fenpyroximate is a slight to
moderate skin sensitizer.
Subchronic oral toxicity studies in the
rat show the primary effects included
decreased body weight and weight gain
at the lowest observed adverse effect
level (LOAEL) while there were
hematological effects at higher doses. In
the 21–day dermal toxicity study in rats,
there were clinical signs in the females
(including red nose/mouth/nasal
discharge); decreased body weights,
body weight gains, and food
consumption in males and females; and
increased liver weights and
hepatocellular necrosis in the females.
In the subchronic oral dog study, there
was bradycardia observed at the LOAEL.
This effect was present at 6 weeks (first
time point measured) and did not
appear to increase in severity with time.
Also observed at this dose level were
diarrhea, decreased body weight, body
weight gain, and food consumption. At
higher doses, there was also emesis
(vomiting). The highest dose resulted in
first- and second-degree heart block,
increased urea concentration, decreased
glucose and altered plasma electrolyte
levels among other signs of toxicity.
In the chronic oral rat and mouse
studies, signs of toxicity were similar to
those in the oral subchronic rat study.
The chronic dog study also revealed
signs of toxicity including bradycardia,
diarrhea, decreased body weight gain,
and food consumption.
The 2–generation reproductive
toxicity study indicated that maternal
(decreased body weight) and offspring
toxicity (decreased lactational weight
gain) occurred at the same dose,
suggesting no evidence of sensitivity or
susceptibility. Reproductive parameters
were not affected in this 2–generation
reproduction study. The rat and rabbit
developmental toxicity studies were
tested at doses that produced minimal
or no maternal or offspring toxicity.
There are no neurotoxicity studies
other than a negative delayed acute
neurotoxicity study in the hen. There
was no indication of neurotoxicity
present in any of the existing
subchronic or chronic toxicity studies.
There was no concern for mutagenic
activity in several studies including:
Salmonella, E. Coli, in vitro mammalian
VerDate Nov<24>2008
12:48 Dec 01, 2009
Jkt 220001
cell gene mutation assay at the
Hypoxanthine guanine phophoribosyl
transferase (HGPRT) locus, mammalian
cell chromosome aberration assay, in
vivo mouse bone marrow micronucleus
assay, DNA repair disk diffusion assay,
and an unscheduled DNA synthesis
assay.
There was no evidence of
carcinogenic potential in either the rat
or mouse study. Therefore,
fenpyroximate is classified as ‘‘not
likely to be carcinogenic to humans’’ by
all relevant routes of 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 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 Berry, Low growing Subgroup 13–
07G,’’ pages 10–13, in docket ID number
EPA–HQ–OPP–2008–0556.
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, a toxicological point of departure
(POD) is identified as the basis for
derivation of reference values for risk
assessment. The POD may be defined as
the highest dose at which no adverse
effects are observed (the NOAEL) in the
toxicology study identified as
appropriate for use in risk assessment.
However, if a NOAEL cannot be
determined, the lowest dose at which
adverse effects of concern are identified
(the LOAEL) or a Benchmark Dose
(BMD) approach is sometimes used for
risk assessment. Uncertainty/safety
factors (UFs) are used in conjunction
with the POD to take into account
uncertainties inherent in the
extrapolation from laboratory animal
data to humans and in the variations in
sensitivity among members of the
human population as well as other
unknowns. Safety is assessed for acute
and chronic dietary risks by comparing
aggregate food and water exposure to
the pesticide to the acute population
adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The
aPAD and cPAD are calculated by
dividing the POD by all applicable UFs.
Aggregate short-term, intermediate-term,
and chronic-term risks are evaluated by
comparing food, water, and residential
exposure to the POD to ensure that the
margin of exposure (MOE) called for by
the product of all applicable UFs is not
exceeded. This latter value is referred to
as the Level of Concern (LOC).
For non-threshold risks, the Agency
assumes that any amount of exposure
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
will lead to some degree of risk. Thus,
the Agency estimates risk in terms of the
probability of an occurrence of the
adverse effect greater than that 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 can be found at
https://www.regulations.gov in document
‘‘Fenpyroximate. Human-Health Risk
Assessment for Proposed Section 3 Uses
on Berry, Low growing Subgroup 13–
07G,’’ page 5, in docket ID number
EPA–HQ–OPP–2008–0556.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to fenpyroximate, EPA
considered exposure under the
petitioned-for tolerance, 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. An acute dietary exposure
assessment was conducted for females
13–49 years old. Since an effect of
concern attributable to a single dose in
toxicity studies was not identified for
the general U.S. population, an acute
dietary exposure assessment was not
performed for subgroups other than
females 13–49 years old.
In estimating acute dietary exposure,
EPA used food consumption
information from the U.S. Department of
Agriculture (USDA) 1994–1996 and
1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). As
to residue levels in food, EPA
conducted acute dietary analysis for
fenpyroximate assuming 100% crop
treated (CT) and existing and proposed
tolerance-level residues for all
commodities. Dietary Exposure
Evaluation Model (DEEM(TM)) (ver. 7.81)
default processing factors were assumed
for all commodities excluding apple,
pear, and grape juice (0.11X); grape,
raisin (2.7X); orange, grapefruit,
tangerine, lemon and lime juice (0.06X);
tomato paste and puree (1.0X); and
peppermint and spearmint oil (0.08X).
The petitioner submitted adequate
tomato processing data indicating that
residues of fenpyroximate per se did not
concentrate in tomato paste or puree as
E:\FR\FM\02DER1.SGM
02DER1
erowe on DSK5CLS3C1PROD with RULES
Federal Register / Vol. 74, No. 230 / Wednesday, December 2, 2009 / Rules and Regulations
all processing factors were <1.0X.
Residues of the Z-isomer did not
concentrate in tomato puree; however,
residues of Z-isomer concentrated
slightly in tomato paste. When residues
are combined, the average processing
factors were <0.89X for tomato paste
and <0.57X for tomato puree. Default
processing factor of 1.0X was assumed
for both tomato paste and tomato puree.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 1994–1996 and 1998
CSFII. As to residue levels in food, EPA
assumed 100% CT and existing and
proposed tolerance-level residues for all
commodities. DEEM(TM) (ver.7.81)
default processing factors were assumed
with the exceptions listed in Unit
III.C.1.
iii. Cancer. Fenpyroximate is
classified as ‘‘not likely to be a human
carcinogen.’’ There was no evidence of
carcinogenicity in mouse studies or in
combined chronic/carcinogenicity
studies in the rat. In addition, bacterial
reverse mutation and in vitro
mammalian cell gene mutation studies
showed no mutagenic effects. Therefore,
a dietary exposure assessment to
evaluate cancer risk was not performed.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue or PCT
information in the dietary assessment
for fenpyroximate. Tolerance level
residues and/or 100% CT 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 proposed application rates
and the environmental fate properties of
fenpyroximate, some surface and
ground water contamination may occur.
However, the risk of water
contamination from parent compound is
relatively low, based on its high
sorption potential. Unlike its parent
compound, the sorption of the M-3
metabolite is much less, and it may
move into water resources more readily.
Environmental fate data indicate that
parent and its Z-isomer are stable to
photolysis in soil and immobile in soil.
Major degradates formed in the aqueous
layer were M-3 (50%), M-8 (36%), M-16
(4-hydroxymethylbenzoic acid, 58%)
VerDate Nov<24>2008
12:48 Dec 01, 2009
Jkt 220001
and M-11 (25 to 30%), and M-3 (>10%),
M-11 (25 to 30%) and M8 (16 to 19%)
in the soil. However, data from a field
dissipation study showed M3 (32%)
being the only significant degradate
found in the field.
Based on the First Index Reservoir
Screening Tool (FIRST) and Screening
Concentration in Ground Water (SCIGROW) models, the estimated drinking
water concentrations (EDWC) of
fenpyroximate, and its degradates, M1
and M3, for acute exposures are
estimated to be 8.74 parts per billion
(ppb) for surface water and 0.001 ppb
for ground water. For chronic exposures
for non-cancer assessments the EDWCs
are estimated to be 0.51 ppb for surface
water and 0.001 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 8.74 ppb was
used to assess the contribution to
drinking water. For chronic dietary risk
assessment, the water concentration
value of 0.51 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).
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
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 website at https://
www.epa.gov/pesticides/cumulative.

D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no concern for prenatal and/or
postnatal toxicity resulting from
exposure to fenpyroximate. There is no
evidence (qualitative or quantitative) of
increased susceptibility following
prenatal and postnatal exposure in
adequate developmental toxicity studies
in the rat and rabbit and a 2–generation
reproduction study in the rat.
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
fenpyroximate is adequate to
characterize potential prenatal and
postnatal risk for infants and children.
Acceptable/guideline studies for
developmental toxicity in rats and
rabbits and reproduction toxicity in rats
are available for FQPA assessment.
EPA began requiring functional
immunotoxicity testing of all food and
non-food use pesticides on December
26, 2007. Since this requirement went
into effect relatively recently, these
studies are not yet available for
fenpyroximate. In the absence of an
immunotoxicity study, EPA evaluated
the available fenpyroximate toxicity
data to determine whether an additional
database uncertainty factor (UF) is
needed to account for potential toxicity.
No evidence of immunotoxicity was
found in studies conducted with
fenpyroximate. Due to the lack of
evidence of immunotoxicity for
fenpyroximate, EPA does not believe
that conducting an immunotoxicity
study with fenpyroximate will result in
a NOAEL less than the chronic
Reference dose (cRfD) NOAEL of 0.97
milligram/kilogram/day (mg/kg/day)
already established for fenpyroximate,
and an additional database UF is not

Federal Register / Vol. 74, No. 230 / Wednesday, December 2, 2009 / Rules and Regulations
erowe on DSK5CLS3C1PROD with RULES
needed to account for potential
immunotoxicity.
Acute and subchronic neurotoxicity
testing in rats is also required as a result
of the changes to the pesticide data
requirements in December of 2007 (40
CFR part 158). Although neurotoxicity
studies in rats have not yet been
submitted, there is no evidence of
neurotoxicity in any study in the
toxicity database for fenpyroximate.
Therefore, EPA has concluded that an
additional UF is not needed to account
for the lack of these data.
ii. There is no indication that
fenpyroximate is a neurotoxic chemical
in available studies, and there is no
need for a developmental neurotoxicity
study or additional UFs to account for
neurotoxicity.
iii. There is no evidence that
fenpyroximate 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 acute and chronic dietary exposure
assessments were performed based on
100% CT and tolerance-level residues
for existing and proposed uses. EPA
made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to fenpyroximate in drinking water.
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 pesticide exposures are safe by
comparing aggregate exposure estimates
to the aPAD and cPAD. The aPAD and
cPAD represent the highest safe
exposures, taking into account all
appropriate SFs. EPA calculates the
aPAD and cPAD by dividing the POD by
all applicable UFs. For linear cancer
risks, EPA calculates the probability of
additional cancer cases given the
estimated aggregate exposure. Shortterm, intermediate-term, and chronicterm risks are evaluated by comparing
the estimated aggregate food, water, and
residential exposure to the POD to
ensure that the MOE called for by the
product of all applicable UFs is not
exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account exposure
estimates from acute dietary
consumption of food and drinking
water. Using the exposure assumptions
discussed in this unit for acute
exposure, the acute dietary exposure
from food and water to fenpyroximate
VerDate Nov<24>2008
12:48 Dec 01, 2009
Jkt 220001
will occupy 7.6% of the aPAD for
females 13–49 years old, the only
population subgroup of interest.
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 42% of
the cPAD for children 1–2 years old, the
population subgroup receiving the
greatest exposure. There are no
residential uses for fenpyroximate.
3. Short-term and intermediate-term
risk. Short-term aggregate exposure
takes into account short-term residential
exposure plus chronic exposure to food
and water (considered to be a
background exposure level). Similarly,
intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Fenpyroximate is not registered for any
use patterns that would result in
residential exposure. Therefore, the
short- and intermediate-term aggregate
risk is the sum of risk from exposure to
fenpyroximate through food and
drinking water and will not be greater
than the chronic aggregate risk.
4. Aggregate cancer risk for U.S.
population. There was no evidence of
carcinogenicity in mouse studies or in
combined chronic/carcinogenicity
studies in the rat. In addition, bacterial
reverse mutation and in vitro
mammalian cell gene mutation studies
showed no mutagenic effects. Therefore,
fenpyroximate is not expected to pose a
cancer risk.
5. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to
fenpyroximate residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An acceptable enforcement method,
gas chromatography with nitrogenphosphorus detector (GC/NPD) method
DFG S19, is available for enforcement of
tolerances for residues in or on plant
commodities. This method has
undergone a petition method validation
and is listed in the U.S. EPA Index of
Residue Analytical Methods under
fenpyroximate, Method ID 2000_109M,
‘‘Quantification of Fenpyroximate
Residues in Raw Agricultural and
Processed Commodities.’’ Method S19
has a limit of quantitation of 0.02 ppm
for the combined residues of
fenpyroximate and its Z-isomer in
strawberries.

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
Codex and Mexican maximum
residue limits (MRLs) are established for
residues of fenpyroximate per se in or
on several crop commodities but not for
the crops requested. Harmonization
with the other Codex and Mexican
MRLs is not possible because the U.S.
tolerance expressions include additional
metabolites/isomers. There are currently
no established Canadian MRLs.
V. Conclusion
Therefore, a tolerance is established
for combined residues of the insecticide
fenpyroximate parent and its Z-isomer,
(E)-1,1-dimethylethyl 4-[[[[(1,3dimethyl-5-phenoxy-1H-pyrazol-4yl)methylene]amino]oxy]methyl]
benzoate, and its Z-isomer, (Z)-1,1dimethylethyl 4-[[[[(1,3-dimethyl-5phenoxy-1H-pyrazol-4yl)methylene]amino]oxy]methyl]
benzoate, in or on berry, low growing,
subgroup 13–07G at 1.0 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA 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 section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
E:\FR\FM\02DER1.SGM
02DER1
Federal Register / Vol. 74, No. 230 / Wednesday, December 2, 2009 / Rules and Regulations
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 section 408(n)(4) of FFDCA. 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) (Public Law 104–4).
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), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).

VII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. 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

II. Petition for Tolerance
In the Federal Register of April 8, 2009 (74 FR 15971) (FRL-8407-
4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
9F7520) by Nichino America, Inc., 4550 New Linden Hill Road, Suite 501,
Wilmington, DE, 19808. The petition requested that 40 CFR 180.566 be
amended by establishing tolerances for combined 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 berry, low
growing, subgroup 13-07G, at 1.0 part per million (ppm). That notice
referenced a summary of the petition prepared by Nichino America, Inc.,
the registrant, which is available to the public 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 section 408(b)(2)(D) of FFDCA, and the factors
specified in section 408(b)(2)(D) of FFDCA, 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 the petitioned-for
tolerance for combined residues of fenpyroximate and its Z-isomer in or
on berry, low growing, subgroup 13-07G, at 1.0 ppm. EPA's assessment of
exposures and risks associated with establishing tolerances follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity,
[[Page 63076]]
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 has moderate oral and inhalation toxicity. It has low
dermal toxicity and is not an eye or skin irritant. Fenpyroximate is a
slight to moderate skin sensitizer.
Subchronic oral toxicity studies in the rat show the primary
effects included decreased body weight and weight gain at the lowest
observed adverse effect level (LOAEL) while there were hematological
effects at higher doses. In the 21-day dermal toxicity study in rats,
there were clinical signs in the females (including red nose/mouth/
nasal discharge); decreased body weights, body weight gains, and food
consumption in males and females; and increased liver weights and
hepatocellular necrosis in the females. In the subchronic oral dog
study, there was bradycardia observed at the LOAEL. This effect was
present at 6 weeks (first time point measured) and did not appear to
increase in severity with time. Also observed at this dose level were
diarrhea, decreased body weight, body weight gain, and food
consumption. At higher doses, there was also emesis (vomiting). The
highest dose resulted in first- and second-degree heart block,
increased urea concentration, decreased glucose and altered plasma
electrolyte levels among other signs of toxicity.
In the chronic oral rat and mouse studies, signs of toxicity were
similar to those in the oral subchronic rat study. The chronic dog
study also revealed signs of toxicity including bradycardia, diarrhea,
decreased body weight gain, and food consumption.
The 2-generation reproductive toxicity study indicated that
maternal (decreased body weight) and offspring toxicity (decreased
lactational weight gain) occurred at the same dose, suggesting no
evidence of sensitivity or susceptibility. Reproductive parameters were
not affected in this 2-generation reproduction study. The rat and
rabbit developmental toxicity studies were tested at doses that
produced minimal or no maternal or offspring toxicity.
There are no neurotoxicity studies other than a negative delayed
acute neurotoxicity study in the hen. There was no indication of
neurotoxicity present in any of the existing subchronic or chronic
toxicity studies.
There was no concern for mutagenic activity in several studies
including: Salmonella, E. Coli, in vitro mammalian cell gene mutation
assay at the Hypoxanthine guanine phophoribosyl transferase (HGPRT)
locus, mammalian cell chromosome aberration assay, in vivo mouse bone
marrow micronucleus assay, DNA repair disk diffusion assay, and an
unscheduled DNA synthesis assay.
There was no evidence of carcinogenic potential in either the rat
or mouse study. Therefore, fenpyroximate is classified as ``not likely
to be carcinogenic to humans'' by all relevant routes of 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 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 Berry, Low
growing Subgroup 13-07G,'' pages 10-13, in docket ID number EPA-HQ-OPP-
2008-0556.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, a toxicological point of departure (POD) is
identified as the basis for derivation of reference values for risk
assessment. The POD may be defined as the highest dose at which no
adverse effects are observed (the NOAEL) in the toxicology study
identified as appropriate for use in risk assessment. However, if a
NOAEL cannot be determined, the lowest dose at which adverse effects of
concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach
is sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the POD to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
dietary risks by comparing aggregate food and water exposure to the
pesticide to the acute population adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The aPAD and cPAD are calculated by
dividing the POD by all applicable UFs. Aggregate short-term,
intermediate-term, and chronic-term risks are evaluated by comparing
food, water, and residential exposure to the POD to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded. This latter value is referred to as the Level of
Concern (LOC).
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
greater than that 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 can be found at https://www.regulations.gov in
document ``Fenpyroximate. Human-Health Risk Assessment for Proposed
Section 3 Uses on Berry, Low growing Subgroup 13-07G,'' page 5, in
docket ID number EPA-HQ-OPP-2008-0556.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fenpyroximate, EPA considered exposure under the
petitioned-for tolerance, 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. An acute dietary exposure
assessment was conducted for females 13-49 years old. Since an effect
of concern attributable to a single dose in toxicity studies was not
identified for the general U.S. population, an acute dietary exposure
assessment was not performed for subgroups other than females 13-49
years old.
In estimating acute dietary exposure, EPA used food consumption
information from the U.S. Department of Agriculture (USDA) 1994-1996
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII). As to residue levels in food, EPA conducted acute dietary
analysis for fenpyroximate assuming 100% crop treated (CT) and existing
and proposed tolerance-level residues for all commodities. Dietary
Exposure Evaluation Model (DEEM\(TM)\) (ver. 7.81) default processing
factors were assumed for all commodities excluding apple, pear, and
grape juice (0.11X); grape, raisin (2.7X); orange, grapefruit,
tangerine, lemon and lime juice (0.06X); tomato paste and puree (1.0X);
and peppermint and spearmint oil (0.08X). The petitioner submitted
adequate tomato processing data indicating that residues of
fenpyroximate per se did not concentrate in tomato paste or puree as
[[Page 63077]]
all processing factors were <1.0X. Residues of the Z-isomer did not
concentrate in tomato puree; however, residues of Z-isomer concentrated
slightly in tomato paste. When residues are combined, the average
processing factors were <0.89X for tomato paste and <0.57X for tomato
puree. Default processing factor of 1.0X was assumed for both tomato
paste and tomato puree.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 CSFII. As to residue levels in food, EPA assumed 100% CT and
existing and proposed tolerance-level residues for all commodities.
DEEM(\TM\) (ver.7.81) default processing factors were assumed with the
exceptions listed in Unit III.C.1.
iii. Cancer. Fenpyroximate is classified as ``not likely to be a
human carcinogen.'' There was no evidence of carcinogenicity in mouse
studies or in combined chronic/carcinogenicity studies in the rat. In
addition, bacterial reverse mutation and in vitro mammalian cell gene
mutation studies showed no mutagenic effects. Therefore, a dietary
exposure assessment to evaluate cancer risk was not performed.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue or PCT information in the dietary
assessment for fenpyroximate. Tolerance level residues and/or 100% CT
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 proposed application rates and the environmental fate
properties of fenpyroximate, some surface and ground water
contamination may occur. However, the risk of water contamination from
parent compound is relatively low, based on its high sorption
potential. Unlike its parent compound, the sorption of the M-3
metabolite is much less, and it may move into water resources more
readily. Environmental fate data indicate that parent and its Z-isomer
are stable to photolysis in soil and immobile in soil. Major degradates
formed in the aqueous layer were M-3 (50%), M-8 (36%), M-16 (4-
hydroxymethylbenzoic acid, 58%) and M-11 (25 to 30%), and M-3 (>10%),
M-11 (25 to 30%) and M8 (16 to 19%) in the soil. However, data from a
field dissipation study showed M3 (32%) being the only significant
degradate found in the field.
Based on the First Index Reservoir Screening Tool (FIRST) and
Screening Concentration in Ground Water (SCI-GROW) models, the
estimated drinking water concentrations (EDWC) of fenpyroximate, and
its degradates, M1 and M3, for acute exposures are estimated to be 8.74
parts per billion (ppb) for surface water and 0.001 ppb for ground
water. For chronic exposures for non-cancer assessments the EDWCs are
estimated to be 0.51 ppb for surface water and 0.001 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 8.74 ppb was used to
assess the contribution to drinking water. For chronic dietary risk
assessment, the water concentration value of 0.51 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). 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 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 website at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA safety
factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no concern for
prenatal and/or postnatal toxicity resulting from exposure to
fenpyroximate. There is no evidence (qualitative or quantitative) of
increased susceptibility following prenatal and postnatal exposure in
adequate developmental toxicity studies in the rat and rabbit and a 2-
generation reproduction study in the rat.
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 fenpyroximate is adequate to
characterize potential prenatal and postnatal risk for infants and
children. Acceptable/guideline studies for developmental toxicity in
rats and rabbits and reproduction toxicity in rats are available for
FQPA assessment.
EPA began requiring functional immunotoxicity testing of all food
and non-food use pesticides on December 26, 2007. Since this
requirement went into effect relatively recently, these studies are not
yet available for fenpyroximate. In the absence of an immunotoxicity
study, EPA evaluated the available fenpyroximate toxicity data to
determine whether an additional database uncertainty factor (UF) is
needed to account for potential toxicity. No evidence of immunotoxicity
was found in studies conducted with fenpyroximate. Due to the lack of
evidence of immunotoxicity for fenpyroximate, EPA does not believe that
conducting an immunotoxicity study with fenpyroximate will result in a
NOAEL less than the chronic Reference dose (cRfD) NOAEL of 0.97
milligram/kilogram/day (mg/kg/day) already established for
fenpyroximate, and an additional database UF is not
[[Page 63078]]
needed to account for potential immunotoxicity.
Acute and subchronic neurotoxicity testing in rats is also required
as a result of the changes to the pesticide data requirements in
December of 2007 (40 CFR part 158). Although neurotoxicity studies in
rats have not yet been submitted, there is no evidence of neurotoxicity
in any study in the toxicity database for fenpyroximate. Therefore, EPA
has concluded that an additional UF is not needed to account for the
lack of these data.
ii. There is no indication that fenpyroximate is a neurotoxic
chemical in available studies, and there is no need for a developmental
neurotoxicity study or additional UFs to account for neurotoxicity.
iii. There is no evidence that fenpyroximate 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 acute and chronic dietary exposure assessments were
performed based on 100% CT and tolerance-level residues for existing
and proposed uses. EPA made conservative (protective) assumptions in
the ground and surface water modeling used to assess exposure to
fenpyroximate in drinking water. 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 pesticide exposures are
safe by comparing aggregate exposure estimates to the aPAD and cPAD.
The aPAD and cPAD represent the highest safe exposures, taking into
account all appropriate SFs. EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs. For linear cancer risks, EPA
calculates the probability of additional cancer cases given the
estimated aggregate exposure. Short-term, intermediate-term, and
chronic-term risks are evaluated by comparing the estimated aggregate
food, water, and residential exposure to the POD to ensure that the MOE
called for by the product of all applicable UFs is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute dietary consumption of food and
drinking water. Using the exposure assumptions discussed in this unit
for acute exposure, the acute dietary exposure from food and water to
fenpyroximate will occupy 7.6% of the aPAD for females 13-49 years old,
the only population subgroup of interest.
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 42% of the cPAD for
children 1-2 years old, the population subgroup receiving the greatest
exposure. There are no residential uses for fenpyroximate.
3. Short-term and intermediate-term risk. Short-term aggregate
exposure takes into account short-term residential exposure plus
chronic exposure to food and water (considered to be a background
exposure level). Similarly, intermediate-term aggregate exposure takes
into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Fenpyroximate is not registered for any use patterns that would
result in residential exposure. Therefore, the short- and intermediate-
term aggregate risk is the sum of risk from exposure to fenpyroximate
through food and drinking water and will not be greater than the
chronic aggregate risk.
4. Aggregate cancer risk for U.S. population. There was no evidence
of carcinogenicity in mouse studies or in combined chronic/
carcinogenicity studies in the rat. In addition, bacterial reverse
mutation and in vitro mammalian cell gene mutation studies showed no
mutagenic effects. Therefore, fenpyroximate is not expected to pose a
cancer risk.
5. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to fenpyroximate residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An acceptable enforcement method, gas chromatography with nitrogen-
phosphorus detector (GC/NPD) method DFG S19, is available for
enforcement of tolerances for residues in or on plant commodities. This
method has undergone a petition method validation and is listed in the
U.S. EPA Index of Residue Analytical Methods under fenpyroximate,
Method ID 2000--109M, ``Quantification of Fenpyroximate Residues in Raw
Agricultural and Processed Commodities.'' Method S19 has a limit of
quantitation of 0.02 ppm for the combined residues of fenpyroximate and
its Z-isomer in strawberries.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
Codex and Mexican maximum residue limits (MRLs) are established for
residues of fenpyroximate per se in or on several crop commodities but
not for the crops requested. Harmonization with the other Codex and
Mexican MRLs is not possible because the U.S. tolerance expressions
include additional metabolites/isomers. There are currently no
established Canadian MRLs.
V. Conclusion
Therefore, a tolerance is established for combined residues of the
insecticide fenpyroximate parent and its Z-isomer, (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 berry, low growing,
subgroup 13-07G at 1.0 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA 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 section 408(d) of FFDCA, such as the tolerance in
this final rule, do not
[[Page 63079]]
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 section 408(n)(4) of FFDCA. 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) (Public Law 104-4).
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), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. 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 this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
