requested that 40 CFR 180.586 be

Bayer CropScience requested
tolerances for residues of clothianidin to
support seed treatment uses, whereas
Valent U.S.A. Corporation and IR-4
requested tolerances to support foliar

applications. Typically, foliar
applications will result in higher
residues than seed treatment uses. In
cases where both use patterns were
requested for the use of clothianidin on
the same commodity, tolerance levels
are being established at the higher level
proposed; however, based upon review
of the data supporting the petitions,
EPA has revised the proposed foliar
application tolerance levels for leafy
vegetable, except brassica, crop group 4;
brassica leafy vegetable, crop group 5;
fruiting vegetable, crop group 8; and
cucurbit vegetable, crop group 9. The
Agency is also revising tolerances for
several other proposed individual and
group commodities.
EPA has determined that the
proposed tolerance in or on bulb onion
group 3 should be established on bulb
onion, group 3-07. The Agency has also
determined that tolerances are not
required for several petitioned-for
commodities. EPA is establishing
tolerances on several commodities that
were not proposed and is deleting
several existing tolerances. Finally, the
Agency is amending an established
tolerance on potato granules/flakes that
was not proposed. The reasons for these
changes are explained in Unit IV.C.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
Consistent with 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

at 3.0 ppm; root vegetable except sugar
beet, subgroup 1B at 0.8 ppm; and
tuberous and corm vegetable, subgroup
1C at 0.3 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,
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.
EPA considered the toxicity of
clothianidin as well as several
metabolites and degradates in
conducting this risk assessment.
Metabolites/degradates of concern in
plants include parent and TMG for leafy
and root and tuber vegetables; parentonly for other crops; and parent, TZNG
and MNG for rotational crops. For
livestock commodities, the metabolites/
degradates of concern include: Parent
and TZU, TZG, TZNG and ATMGpyruvate for ruminants; and parent and
TZU, TZG, TZNG, and ATG-acetate for
poultry. Acute toxicity and genotoxicity
data are available for several
metabolites/degradates of clothianidin.
Given that the points of departure (POD)
used for risk assessment are well below
the lethal dose LD50 levels observed in
the acute toxicology studies and that
clothianidin and its metabolites/
degradates of toxicological concern are
similar in structure, EPA is assuming
that these compounds are
toxicologically equivalent to
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
clothianidin with respect to the
endpoints being used for risk
assessment.
Clothianidin and its metabolites and
degradates have relatively low acute
toxicity via oral, dermal and inhalation
routes of exposure; however, acute oral
administration of clothianidin in mice
and the TMG metabolite in rats showed
evidence of increased relative toxicity.
There is no evidence of dermal
sensitization or eye irritation with the
exception of the clothianidin-triazan
intermediate, which is a dermal
sensitizer. The available data indicate
that there are no consistent target organs
in mammals; however, some effects
noted in the liver, hematopoietic system
and kidney are similar to effects from
other neonicotinoid insecticides.
In subchronic oral studies, the dog
seemed to be more sensitive to
clothianidin than the rat. In addition to
decreases in body weight and body
weight gains observed in both animals,
dogs also displayed decreased white
blood cells, albumin and total protein,
as well as some anemia. Long-term
dietary administration of clothianidin
did not result in a wider spectrum of
effects in the dog; in contrast, the
chronic feeding studies in rats showed
additional effects in the liver, ovaries
and kidneys. In the mouse chronic oral
study, increases in vocalization and
decreases in body weight and body
weight gain were noted.
Based on the lack of significant tumor
increases in two adequate rodent
carcinogenicity studies, EPA has
classified clothianidin as ‘‘not likely to
be carcinogenic to humans.’’ A bone
marrow micronucleus assay in mice
showed that clothianidin is neither
clastogenic nor aneugenic up to a toxic
oral dose. Additionally, a study on the
livers of Wistar male mice showed no
induction of unscheduled DNA
synthesis up to the limit dose; therefore,
mutagenicity is not of concern.
Clinical signs of neurotoxicity were
exhibited in both rats (decreased
arousal, motor activity and locomotor
activity) and mice (decreased
spontaneous motor activity, tremors and
deep respirations) in acute neurotoxicity
studies following exposure by gavage;
however, no indications of
neurotoxicity were observed following
dietary exposure in the subchronic
neurotoxicity study in rats.
There was no evidence of increased
quantitative or qualitative susceptibility
of rat or rabbit fetuses following in utero
exposure to clothianidin in
developmental studies; however,
increased quantitative susceptibility of
rat pups was seen in both the
reproduction and developmental
PO 00000
Frm 00027
Fmt 4700

65023
neurotoxicity studies. In the rat
reproduction study, offspring toxicity
(decreased body weight gains and
absolute thymus weights in pups,
delayed sexual maturation and an
increase in stillbirths) was observed in
the absence of maternal effects. In the
developmental neurotoxicity study in
rats, offspring effects (decreased body
weights, body weight gains, motor
activity and acoustic startle response
amplitude) were noted at doses lower
than those resulting in maternal
toxicity.
Decreased absolute and relative
thymus and spleen weights were
observed in multiple studies; these
studies showed possible evidence of
effects on the immune system. In
addition, juvenile rats in the rat
reproduction study appeared to be more
susceptible to these effects. However, a
guideline immunotoxicity study showed
no evidence of clothianidin-mediated
immunotoxicity in adult rats and a
developmental immunotoxicity study
demonstrated no increased
susceptibility for offspring with regard
to immunotoxicity.
Specific information on the studies
received and the nature of the adverse
effects caused by clothianidin 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://

docket ID number EPA–HQ–OPP–2008–

B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, a toxicological 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
E:\FR\FM\09DER1.SGM
09DER1
65024
Federal Register / Vol. 74, No. 235 / Wednesday, December 9, 2009 / Rules and Regulations
WReier-Aviles on DSKGBLS3C1PROD with RULES
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-, intermediate-, 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.

endpoints for clothianidin used for
human risk assessment can be found at

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to clothianidin, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing clothianidin tolerances in 40
CFR 180.586. EPA assessed dietary
exposures from clothianidin 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.
In estimating acute dietary exposure,
EPA used food consumption
information from the U.S. Department of
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
Agriculture (USDA) 1994–1996 and
1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). As
to residue levels in food, EPA used
tolerance-level residues, empirical
processing factors and assumed 100
percent crop treated (PCT) for all
commodities. Clothianidin is a major
metabolite of thiamethoxam, and there
are a number of crops for which uses of
both clothianidin and thiamethoxam
have been registered. The labels for the
various end-use products containing
these active ingredients prohibit the
application of both active ingredients to
the same crop during a growing cycle.
Due to that restriction and the
assumption of 100 PCT, a single value
reflecting the greatest clothianidin
residue from either active ingredient has
been used for crops listed for use with
both active ingredients (versus
combined estimates from clothianidin
and from thiamethoxam). Generally, this
assessment uses the established or
recommended clothianidin tolerance for
crops having tolerances for both
compounds (the exception being lowgrowing berry, subgroup 13-07G, which
is based on observed clothianidin
residues in thiamethoxam strawberry
field trials). For foods with
thiamethoxam tolerances but without
clothianidin tolerances, maximum
residues of clothianidin observed in
thiamethoxam field trials have been
used in these assessments. These
include meats, meat by-products,
artichoke, tropical fruits, coffee, hop,
mint, rice, and strawberry. The
metabolism of clothianidin is complex,
with a few major (> 10% of the total
radioactive residues) and numerous
minor metabolites. Metabolites/
degradates of concern in plants include
clothianidin and TMG for leafy, root
and tuber vegetables; parent-only for
other crops; and parent, TZNG and
MNG for rotational crops. For livestock
commodities, the metabolites of concern
include: parent and TZU, TZG, TZNG,
and ATMG-pyruvate for ruminants; and
parent and TZU, TZG, TZNG, and ATGacetate for poultry. For leafy vegetables
the EPA required analysis for residues
of TMG along with parent in field trial
samples. Residues of TMG were shown
to occur in leafy vegetables at levels
approximately tenfold below those of
clothianidin. EPA has not included
these metabolites in the tolerance
expression for plant or animal
commodities because the metabolites
are only found in certain commodities,
including the metabolites would create
tolerance harmonization issues with
Canada, and monitoring residues of
clothianidin based on parent only
PO 00000
Frm 00028
Fmt 4700
Sfmt 4700
would be representative of total
clothianidin residues and thus adequate
for enforcement. Because the
metabolites are not included in the
tolerance expressions, an adjustment
factor of 1.1 has been incorporated into
the assessment for leafy vegetables to
account for the presence of the
metabolite TMG, and an adjustment
factor of 1.5 has been incorporated for
livestock-derived commodities (milk) to
account for the presence of metabolites
TZU, TZG, TZNG, ATMG-pyruvate and
ATG-acetate. The 1.1 adjustment factor
is based on field trial data showing TMG
does not exceed 10% of the parent
compound residue level in leafy
vegetables and the 1.5 factor was based
on metabolism data.
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
assessed chronic dietary exposure using
the same residue information and
assumptions regarding metabolites/
degradates as in the acute exposure
analysis.
iii. Cancer. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
EPA has classified clothianidin as ‘‘not
likely to be carcinogenic to humans.’’
Therefore, a quantitative exposure
assessment to evaluate cancer risk is
unnecessary.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue and/or PCT
information in the dietary assessment
for clothianidin. 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 clothianidin in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
clothianidin. 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) and Screening
Concentration in Ground Water (SCIGROW) models, the estimated drinking
water concentrations (EDWCs) of
clothianidin for surface water are
estimated to be 7.29 parts per billion
(ppb) for acute exposures and 1.35 ppb
for chronic exposures. For ground
water, the EDWC is estimated to be 5.88
ppb.

Federal Register / Vol. 74, No. 235 / Wednesday, December 9, 2009 / Rules and Regulations
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. The
water concentration value of 7.29 ppb
was used to assess the contribution to
drinking water for the acute dietary
assessment. For chronic dietary risk
assessment, the water concentration of
value 5.88 ppb was used.
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).
Clothianidin is currently registered
for use on turf. Residential handler
exposure is not expected from the
currently registered or proposed uses of
clothianidin since these products are to
be applied by commercial applicators.
Adult short- and intermediate-term
postapplication exposures were
assessed for dermal exposures from
commercial applications (via granular
push-type spreaders), dermal postapplication contact and golfer
postapplication contact. For toddlers,
short- and intermediate-term
postapplication incidental oral (hand-tomouth and soil ingestion) and dermal
risks were assessed for exposure to
treated turf.
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.’’
Clothianidin is a member of the
neonicotinoid class of pesticides and is
a metabolite of another neonicotinoid,
thiamethoxam. Structural similarities or
common effects do not constitute a
common mechanism of toxicity.
Evidence is needed to establish that the
chemicals operate by the same, or
essentially the same sequence of major
biochemical events (EPA, 2002).
Although clothianidin and
thiamethoxam bind selectively to insect
nicotinic acetylcholine receptors
(nAChR), the specific binding site(s)/
receptor(s) for clothianidin,
thiamethoxam, and the other
neonicotinoids are unknown at this
time. Additionally, the commonality of
the binding activity itself is uncertain,
as preliminary evidence suggests that
clothianidin operates by direct
competitive inhibition, while
thiamethoxam is a non competitive
inhibitor. Furthermore, even if future
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
research shows that neonicotinoids
share a common binding activity to a
specific site on insect nicotinic
acetylcholine receptors, there is not
necessarily a relationship between this
pesticidal action and a mechanism of
toxicity in mammals. Structural
variations between the insect and
mammalian nAChRs produce
quantitative differences in the binding
affinity of the neonicotinoids towards
these receptors, which, in turn, confers
the notably greater selective toxicity of
this class towards insects, including
aphids and leafhoppers, compared to
mammals. While the insecticidal action
of the neonicotinoids is neurotoxic, the
most sensitive regulatory endpoint for
clothianidin is based on unrelated
effects in mammals, including changes
in body and thymus weights, delays in
sexual maturation, and still births.
Additionally, the most sensitive
toxicological effect in mammals differs
across the neonicotinoids (e.g.,
testicular tubular atrophy with
thiamethoxam; mineralized particles in
thyroid colloid with imidaclopid). Thus,
there is currently no evidence to
indicate that neonicotinoids share
common mechanisms of toxicity, and
EPA is not following a cumulative risk
approach based on a common
mechanism of toxicity for the
neonicotinoids. 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 the policy statements
concerning common mechanism
determinations and procedures for
cumulating effects from substances
found to have a common mechanism
released by EPA’s Office of Pesticide
Programs on 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
Food Quality Protection Act (FQPA)
safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional SF when reliable data
available to EPA support the choice of
a different factor.

2. Prenatal and postnatal sensitivity.
The toxicology data for clothianidin
provide no indication of increased
quantitative or qualitative susceptibility,
as compared to adults, of rat and rabbit
fetuses to in utero exposure in
developmental studies. However,
increased quantitative susceptibility
was observed in both the developmental
neurotoxicity and rat multi–generation
reproduction studies. In the
developmental neurotoxicity study,
offspring toxicity (decreased body
weight gains, motor activity and
acoustic startle response) was seen at a
lower dose than that which caused
maternal toxicity. In the 2–generation
rat reproduction study, offspring
toxicity (decreased body weight gains,
delayed sexual maturation in males,
decreased absolute thymus weights in
F1 pups of both sexes and an increase
in stillbirths in both generations) was
seen at a dose lower than that which
caused parental toxicity.
3. Conclusion. In the final rule
published in the Federal Register of
February 6, 2008 (73 FR 6851) (FRL–
8346–9), EPA had previously
determined that the FQPA SF for
clothianidin should be retained at 10X
because EPA had required the
submission of a developmental
immunotoxicity study to address the
combination of evidence of decreased
absolute and adjusted organ weights of
the thymus and spleen in multiple
studies in the clothianidin data base,
and evidence showing that juvenile rats
in the 2–generation reproduction study
appear to be more susceptible to these
potential immunotoxic effects. In the
absence of a developmental
immunotoxicity study EPA concluded
that there was sufficient uncertainty
regarding immunotoxic effects in the
young that the 10X FQPA factor should
be retained as a database uncertainty
factor. Since that determination, EPA
has received and reviewed an
acceptable/guideline developmental
immunotoxicity study, which
demonstrated no treatment-related
effects. Taking the results of this study
into account as well as the rest of the
data on clothianidin, EPA has
determined that reliable data show the
safety of infants and children would be
adequately protected if the FQPA SF for
clothianidin were reduced to 1X. That
decision is based on the following
findings:
i. The toxicity database for
clothianidin is complete. As noted, the
prior data gap concerning
developmental immunotoxicity has
been addressed by the submission of an
acceptable developmental
immunotoxicity study.

ii. A rat developmental neurotoxicity
study is available and shows evidence
of increased quantitative susceptibility
of offspring. However, EPA considers
the degree of concern for the
developmental neurotoxicity study to be
low for prenatal and postnatal toxicity
because the NOAEL and LOAEL were
well characterized, and the doses and
endpoints selected for risk assessment
are protective of the observed
susceptibility; therefore, there are no
residual concerns regarding effects in
the young.
iii. While the rat multi-generation
reproduction study showed evidence of
increased quantitative susceptibility of
offspring compared to adults, the degree
of concern is low because the study
NOAEL and LOAEL have been selected
for risk assessment purposes for relevant
exposure routes and durations. In
addition, the potential immunotoxic
effects observed in the study have been
further characterized with the
submission of a developmental
immunotoxicity study that showed no
evidence of susceptibility. As a result,
there are no concerns or residual
uncertainties for prenatal and postnatal
toxicity after establishing toxicity
endpoints and traditional UFs to be
used in the risk assessment for
clothianidin.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on assumptions
that were judged to be highly
conservative and health-protective for
all durations and population subgroups,
including tolerance-level residues,
adjustment factors from metabolite data,
empirical processing factors, and 100
PCT for all commodities. Additionally,
EPA made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to clothianidin in drinking water. EPA
used similarly conservative assumptions
to assess postapplication exposure of
children and adults as well as incidental
oral exposure of toddlers. These
assessments will not underestimate the
exposure and risks posed by
clothianidin.
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
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
additional cancer cases 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 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 clothianidin will
occupy 23% of the aPAD for children 1
to 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 clothianidin
from food and water will utilize 19% of
the cPAD for children 1 to 2 years old,
the population group receiving the
greatest exposure. Based on the
explanation in Unit III.C.3., regarding
residential use patterns, chronic
residential exposure to residues of
clothianidin is not expected.
3. Short- and intermediate-term risk.
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).
Clothianidin is currently registered
for use on turf that could result in shortand intermediate-term residential
exposure and the Agency has
determined that it is appropriate to
aggregate chronic exposure through food
and water with short- and intermediateterm residential exposures to
clothianidin. Using the exposure
assumptions described in this unit for
short- and intermediate-term exposures,
EPA has concluded the combined shortand intermediate-term food, water, and
residential exposures aggregated result
in aggregate MOEs of greater than 380
for all population subgroups. As the
aggregate MOEs are greater than 100 (the
LOC) for all population subgroups,
including infants and children, shortand intermediate-term aggregate
exposures to clothianidin are not of
concern to EPA.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in mice and
rats at doses that were judged to be
adequate to assess the carcinogenic
potential, clothianidin was classified as
‘‘not likely to be carcinogenic to
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
humans,’’ and 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 clothianidin
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate liquid chromatography/
mass spectrometry/mass spectrometry
(LC/MS/MS) enforcement methodology
is available to enforce the tolerance
expression for both plant and animal
commodities and has been forwarded to
the Food and Drug Administration for
inclusion in the Pesticide Analytical
Manual (PAM), Volume II. The method
may be requested from: Chief,
Analytical Chemistry Branch,
Environmental Science Center, 701
Mapes Rd., Ft. Meade, MD 20755–5350;
telephone number: (410) 305–2905; email address: residuemethods@epa.gov.
B. International Residue Limits
In order to harmonize with Canadian
maximum residue limits (MRLs) on
potato tubers at 0.3 ppm; potato chips
at 0.6 ppm and potato granules/flakes at
1.5 ppm, EPA has recommended the
following tolerances: Vegetable,
tuberous and corm, subgroup 1C (which
includes potato) at 0.3 ppm; potato,
chips at 0.6 ppm; and potato granules/
flakes at 1.5 ppm. Additionally, Canada
is currently reviewing a petition to
establish a tolerance in or on the stone
fruit (including peaches) crop group at
0.8 ppm. A tolerance on peach at 0.80
ppm is being recommended by EPA to
harmonize with Canada’s recommended
stone fruit MRL. There are currently no
Canadian MRLs established for residues
of clothianidin in or on other
commodities associated with these
petitions. There are currently no Codex
or Mexican MRLs established for
residues of clothianidin in or on
commodities associated with these
petitions.
C. Revisions to Petitioned-For
Tolerances
EPA has revised the proposed
tolerance levels for foliar applications of
clothianidin on the following
commodities: Leafy vegetable, crop
group 4 from 3.5 ppm to 3.0 ppm;
brassica vegetable, crop group 5 from
3.0 ppm to 1.9 ppm; fruiting vegetable,
crop group 8 from 0.25 to 0.20 ppm; and
cucurbit vegetable, crop group 9 from
0.05 to 0.06 ppm. EPA has also revised
the proposed tolerance levels in or on
E:\FR\FM\09DER1.SGM

WReier-Aviles on DSKGBLS3C1PROD with RULES
Federal Register / Vol. 74, No. 235 / Wednesday, December 9, 2009 / Rules and Regulations
soybean, seed from 0.03 ppm to 0.02
ppm; root vegetable, except sugar beet,
subgroup 1B from 0.60 ppm to 0.8 ppm;
bulb vegetable group 3-07 from 0.2 ppm
to 0.45 ppm; and wheat, straw from 0.04
ppm to 0.05 ppm; and has revised the
proposed tolerance amendment for
cotton, undelinted seed (the preferred
commodity definition for cotton, seed)
from 0.25 to 0.20. EPA revised the
tolerance levels based on analysis of the
residue field trial data using the
Agency’s Tolerance Spreadsheet in
accordance with the Agency’s Guidance
for Setting Pesticide Tolerances Based
on Field Trial Data.
The Agency has also revised
tolerances in order to harmonize U.S.
MRLs with currently established or
pending Canadian MRLs for peach from
0.7 ppm to 0.80 ppm; and for tuberous
and corm vegetable, group 1C (based on
the a seed piece treatment which results
in the highest residue) from 0.2 ppm to
0.3 ppm. Additionally, the Agency has
established a tolerance in or on potato,
chips at 0.6 ppm; and has increased a
currently-established tolerance in or on
potato, granules/flakes from 0.08 to 1.5
ppm to harmonize with Canadian MRLs
on the commodities.
EPA has also determined that
individual tolerances are not necessary
for several petitioned-for commodities.
A request to increase an existing potato
tolerance from 0.05 ppm to 0.6 ppm is
not necessary because potato is
superseded by inclusion in the tuberous
and corm subgroup 1C; thus, the
existing potato tolerance is being
deleted. A proposed tolerance on
vegetable, leafy greens, except brassica,
subgroup 4A at 1.1 ppm is not
necessary, as the subgroup tolerance is
superseded by inclusion in the leafy
vegetable except brassica, group 4.
Separate tolerances in or on soybean,
hulls; soybean, meal; and soybean, oil
are not required because adequate
soybean processing data indicate that
quantifiable residues are unlikely to
occur in soybean processed fractions;
thus, only a soybean seed tolerance is
being established. Separate tolerances in
or on cotton, meal; cotton, hulls; and
cotton, refined oil are not required
because residues were reduced in these
commodities; therefore, the existing
cotton, undelinted seed (the preferred
commodity term for cotton, seed) and
cotton, gin byproducts (the preferred
commodity term for cotton, gin trash)
tolerances are being amended to reflect
increased tolerances of 0.20 and 4.5
ppm, respectively. Finally, adequate
processing data indicate that separate
tolerances in or on tomato, paste at 0.08
ppm and tomato, puree at 0.07 ppm are
not necessary; therefore, only a fruiting
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
vegetable group 8 (including tomato)
tolerance is required.
EPA has reviewed the available
wheat, corn and sorghum data and has
determined that sufficient data are
available to establish the following
group tolerances: Grain, cereal, forage,
fodder and straw, group 16, except rice,
forage at 0.35 ppm; grain, cereal, forage,
fodder and straw, group 16, except rice,
hay at 0.07 ppm; grain, cereal, forage,
fodder and straw, group 16, except rice,
stover at 0.1 ppm; grain, cereal, forage,
fodder and straw, group 16, except rice,
straw at 0.05 ppm. The registrant
petitioned for a crop group tolerance on
the Cereal Grains Group (Crop Group
15) but only petitioned for individual
tolerances in or on wheat, forage (at 0.35
ppm); wheat, hay (at 0.07 ppm); and
wheat, straw (at 0.04); and not
tolerances on the crop group covering
Forage, Fodder, and Straw of the Cereal
Grains (Crop Group 16). However, EPA
has determined that tolerances for group
16 are appropriate because the
petitioned-for wheat feed item
tolerances when considered in
conjunction with the existing feed item
tolerances for corn and sorghum
satisfied the requirements for
establishment of Crop Group 16
tolerances. The Crop Group 16
tolerances are being limited like the
Crop Group 15 tolerance to exclude rice.
Additionally, the following established
tolerances are being deleted because
they are superseded by inclusion in
group 16: corn, field, forage at 0.10 ppm;
corn, field, stover at 0.10 ppm; corn,
pop, stover at 0.10 ppm; corn, sweet,
forage at 0.10 ppm; corn, sweet, stover
at 0.10; sorghum, forage and stover at
0.01 ppm; and grain, cereal, forage,
fodder and straw, group 16 at 0.02 ppm
(a tolerance resulting from indirect/
inadvertent residues of clothianidin).
Finally, tolerances of clothianidin in or
on corn, field grain at 0.01 ppm; corn,
pop, grain at 0.01 ppm; corn, sweet,
kernel plus cob with husk removed at
0.01 ppm; and sorghum, grain at 0.01
ppm are being deleted because they are
being superseded by inclusion in the
grain, cereal, group 15.
Additionally, a final rule published in
the Federal Register of December 7,
2007 (72 FR 69150) (FRL–8343–1) that
amended the existing bulb vegetable
group 3 by adding several commodities;
the updated group was renamed the
bulb vegetable group 3-07. This rule, as
well as the earlier May 23, 2007
proposed rule (72 FR 28920) (FRL–
8126–1) stated that, for existing
petitions for which a Notice of Filing
had been published, the Agency would
attempt to conform these petitions to the
rule. Therefore, consistent with this
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
65027
rule, EPA has assessed for and is
establishing a tolerance for group 3-07
instead of the proposed bulb vegetable
group 3.
Finally, EPA has revised the tolerance
expression to clarify (1) that, as
provided in FFDCA section 408(a)(3),
the tolerance covers metabolites and
degradates of clothianidin not
specifically mentioned; and (2) that
compliance with the specified tolerance
levels is to be determined by measuring
only the specific compounds mentioned
in the tolerance expression.
V. Conclusion
Therefore, tolerances are established
for residues of clothianidin, (E)-1-(2chloro-1,3-thiazol-5-ylmethyl)-3-methyl2-nitroguanidine, in or on almond, hulls
at 1.5 ppm; berry, low-growing,
subgroup 13-07H, except strawberry at
0.01 ppm; fig at 0.05; grain, cereal,
forage, fodder and straw, group 16,
except rice, forage at 0.35 ppm; grain,
cereal, forage, fodder and straw, group
16, except rice, hay at 0.07 ppm; grain,
cereal, forage, fodder and straw, group
16, except rice, stover at 0.1 ppm; grain,
cereal, forage, fodder and straw, group
16, except rice, straw at 0.05 ppm; grain,
cereal, group 15, except rice at 0.01
ppm; nut, tree, group 14 at 0.01 ppm;
peach at 0.80 ppm; pomegranate at 0.20
ppm; potato, chips at 0.6 ppm; soybean,
seed at 0.02 ppm; vegetable, brassica,
leafy, group 5 at 1.9 ppm; vegetable,
bulb, group 3-07 at 0.45 ppm; vegetable,
cucurbit, group 9 at 0.06 ppm;
vegetable, fruiting, group 8 at 0.20 ppm;
vegetable, leafy, except brassica, group 4
at 3.0 ppm; vegetable, root, except sugar
beet, subgroup 1B at 0.8 ppm; and
vegetable, tuberous and corm, subgroup
1C at 0.3 ppm. Additionally, tolerances
are amended for residues of clothianidin
in or on cotton, gin byproducts from
0.01 ppm to 4.5 ppm; cotton, undelinted
seed from 0.01 ppm to 0.20 ppm; and
potato, granules/flakes from 0.08 to 1.5
ppm. This regulation deletes a tolerance
in or on potato at 0.05 ppm; corn, field,
forage at 0.10 ppm; corn, field, grain at
0.01 ppm; corn, field, stover at 0.10
ppm; corn, pop, grain at 0.01 ppm; corn,
pop, stover at 0.10 ppm; corn, sweet,
forage at 0.10 ppm; corn, sweet, kernel
plus cob with husk removed at 0.01
ppm; corn, sweet, stover at 0.10 ppm;
and sorghum, forage, grain, stover at
0.01 ppm. Finally, this regulation
deletes a tolerance for indirect/
inadvertent residues of clothianidin in
or on grain, cereal, forage, fodder and
straw, group 16 at 0.02 ppm. Also, the
introductory text in 40 CFR 180.586(a),
(b) and (d), which includes the tolerance
expression, are revised.

VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
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
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
VerDate Nov<24>2008
14:53 Dec 08, 2009
Jkt 220001
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).

to the notice of filing.
In the Federal Register of May 6, 2009 (74 FR 20947) (FRL-8412-7),
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 9F7530)
by Valent U.S.A. Corporation, P.O. Box 8025, Walnut Creek, CA 94596.
The petition requested that 40 CFR 180.586 be amended by establishing
tolerances for residues of the insecticide clothianidin, (E)-1-(2-
chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-nitroguanidine, in or on fig
at 0.05 ppm and pomegranate at 0.2 ppm. That notice referenced a
summary of the petition prepared by Valent, U.S.A. Corporation, the
registrant, which is available to the public in the docket, https://www.regulations.gov. This petition was assigned Docket No. OPP-2009-
0262. There were no comments received in response to the notice of
filing.
Bayer CropScience requested tolerances for residues of clothianidin
to support seed treatment uses, whereas Valent U.S.A. Corporation and
IR-4 requested tolerances to support foliar applications. Typically,
foliar applications will result in higher residues than seed treatment
uses. In cases where both use patterns were requested for the use of
clothianidin on the same commodity, tolerance levels are being
established at the higher level proposed; however, based upon review of
the data supporting the petitions, EPA has revised the proposed foliar
application tolerance levels for leafy vegetable, except brassica, crop
group 4; brassica leafy vegetable, crop group 5; fruiting vegetable,
crop group 8; and cucurbit vegetable, crop group 9. The Agency is also
revising tolerances for several other proposed individual and group
commodities.
EPA has determined that the proposed tolerance in or on bulb onion
group 3 should be established on bulb onion, group 3-07. The Agency has
also determined that tolerances are not required for several
petitioned-for commodities. EPA is establishing tolerances on several
commodities that were not proposed and is deleting several existing
tolerances. Finally, the Agency is amending an established tolerance on
potato granules/flakes that was not proposed. The reasons for these
changes are explained in Unit IV.C.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.''
Consistent with 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

and tuberous and corm vegetable, subgroup 1C at 0.3 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, 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.
EPA considered the toxicity of clothianidin as well as several
metabolites and degradates in conducting this risk assessment.
Metabolites/degradates of concern in plants include parent and TMG for
leafy and root and tuber vegetables; parent-only for other crops; and
parent, TZNG and MNG for rotational crops. For livestock commodities,
the metabolites/degradates of concern include: Parent and TZU, TZG,
TZNG and ATMG-pyruvate for ruminants; and parent and TZU, TZG, TZNG,
and ATG-acetate for poultry. Acute toxicity and genotoxicity data are
available for several metabolites/degradates of clothianidin. Given
that the points of departure (POD) used for risk assessment are well
below the lethal dose LD50 levels observed in the acute
toxicology studies and that clothianidin and its metabolites/degradates
of toxicological concern are similar in structure, EPA is assuming that
these compounds are toxicologically equivalent to clothianidin with
respect to the endpoints being used for risk assessment.
Clothianidin and its metabolites and degradates have relatively low
acute toxicity via oral, dermal and inhalation routes of exposure;
however, acute oral administration of clothianidin in mice and the TMG
metabolite in rats showed evidence of increased relative toxicity.
There is no evidence of dermal sensitization or eye irritation with the
exception of the clothianidin-triazan intermediate, which is a dermal
sensitizer. The available data indicate that there are no consistent
target organs in mammals; however, some effects noted in the liver,
hematopoietic system and kidney are similar to effects from other
neonicotinoid insecticides.
In subchronic oral studies, the dog seemed to be more sensitive to
clothianidin than the rat. In addition to decreases in body weight and
body weight gains observed in both animals, dogs also displayed
decreased white blood cells, albumin and total protein, as well as some
anemia. Long-term dietary administration of clothianidin did not result
in a wider spectrum of effects in the dog; in contrast, the chronic
feeding studies in rats showed additional effects in the liver, ovaries
and kidneys. In the mouse chronic oral study, increases in vocalization
and decreases in body weight and body weight gain were noted.
Based on the lack of significant tumor increases in two adequate
rodent carcinogenicity studies, EPA has classified clothianidin as
``not likely to be carcinogenic to humans.'' A bone marrow micronucleus
assay in mice showed that clothianidin is neither clastogenic nor
aneugenic up to a toxic oral dose. Additionally, a study on the livers
of Wistar male mice showed no induction of unscheduled DNA synthesis up
to the limit dose; therefore, mutagenicity is not of concern.
Clinical signs of neurotoxicity were exhibited in both rats
(decreased arousal, motor activity and locomotor activity) and mice
(decreased spontaneous motor activity, tremors and deep respirations)
in acute neurotoxicity studies following exposure by gavage; however,
no indications of neurotoxicity were observed following dietary
exposure in the subchronic neurotoxicity study in rats.
There was no evidence of increased quantitative or qualitative
susceptibility of rat or rabbit fetuses following in utero exposure to
clothianidin in developmental studies; however, increased quantitative
susceptibility of rat pups was seen in both the reproduction and
developmental neurotoxicity studies. In the rat reproduction study,
offspring toxicity (decreased body weight gains and absolute thymus
weights in pups, delayed sexual maturation and an increase in
stillbirths) was observed in the absence of maternal effects. In the
developmental neurotoxicity study in rats, offspring effects (decreased
body weights, body weight gains, motor activity and acoustic startle
response amplitude) were noted at doses lower than those resulting in
maternal toxicity.
Decreased absolute and relative thymus and spleen weights were
observed in multiple studies; these studies showed possible evidence of
effects on the immune system. In addition, juvenile rats in the rat
reproduction study appeared to be more susceptible to these effects.
However, a guideline immunotoxicity study showed no evidence of
clothianidin-mediated immunotoxicity in adult rats and a developmental
immunotoxicity study demonstrated no increased susceptibility for
offspring with regard to immunotoxicity.
Specific information on the studies received and the nature of the
adverse effects caused by clothianidin 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 the document ``Clothianidin: Human Health Risk
Assessment for Proposed Uses on Berries (Group 13-07H), Brassica
Vegetables (Group 5), Cotton, Cucurbit Vegetables (Group 9), Fig,
Fruiting Vegetables (Group 8), Leafy Green Vegetables (Group 4A),
Peach, Pomegranate, Soybean, Tree Nuts (Group 14), and Tuberous and
Corm Vegetables (Group 1C),'' pages 46-54 in docket ID number EPA-HQ-
OPP-2008-0945.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, a toxicological 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
[[Page 65024]]
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-, intermediate-, 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.

human risk assessment can be found at https://www.regulations.gov in the

Nuts (Group 14), and Tuberous and Corm Vegetables (Group 1C),'' page 23
in docket ID number EPA-HQ-OPP-2008-0945.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to clothianidin, EPA considered exposure under the petitioned-
for tolerances as well as all existing clothianidin tolerances in 40
CFR 180.586. EPA assessed dietary exposures from clothianidin 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.
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 used tolerance-level
residues, empirical processing factors and assumed 100 percent crop
treated (PCT) for all commodities. Clothianidin is a major metabolite
of thiamethoxam, and there are a number of crops for which uses of both
clothianidin and thiamethoxam have been registered. The labels for the
various end-use products containing these active ingredients prohibit
the application of both active ingredients to the same crop during a
growing cycle. Due to that restriction and the assumption of 100 PCT, a
single value reflecting the greatest clothianidin residue from either
active ingredient has been used for crops listed for use with both
active ingredients (versus combined estimates from clothianidin and
from thiamethoxam). Generally, this assessment uses the established or
recommended clothianidin tolerance for crops having tolerances for both
compounds (the exception being low-growing berry, subgroup 13-07G,
which is based on observed clothianidin residues in thiamethoxam
strawberry field trials). For foods with thiamethoxam tolerances but
without clothianidin tolerances, maximum residues of clothianidin
observed in thiamethoxam field trials have been used in these
assessments. These include meats, meat by-products, artichoke, tropical
fruits, coffee, hop, mint, rice, and strawberry. The metabolism of
clothianidin is complex, with a few major (> 10% of the total
radioactive residues) and numerous minor metabolites. Metabolites/
degradates of concern in plants include clothianidin and TMG for leafy,
root and tuber vegetables; parent-only for other crops; and parent,
TZNG and MNG for rotational crops. For livestock commodities, the
metabolites of concern include: parent and TZU, TZG, TZNG, and ATMG-
pyruvate for ruminants; and parent and TZU, TZG, TZNG, and ATG-acetate
for poultry. For leafy vegetables the EPA required analysis for
residues of TMG along with parent in field trial samples. Residues of
TMG were shown to occur in leafy vegetables at levels approximately
tenfold below those of clothianidin. EPA has not included these
metabolites in the tolerance expression for plant or animal commodities
because the metabolites are only found in certain commodities,
including the metabolites would create tolerance harmonization issues
with Canada, and monitoring residues of clothianidin based on parent
only would be representative of total clothianidin residues and thus
adequate for enforcement. Because the metabolites are not included in
the tolerance expressions, an adjustment factor of 1.1 has been
incorporated into the assessment for leafy vegetables to account for
the presence of the metabolite TMG, and an adjustment factor of 1.5 has
been incorporated for livestock-derived commodities (milk) to account
for the presence of metabolites TZU, TZG, TZNG, ATMG-pyruvate and ATG-
acetate. The 1.1 adjustment factor is based on field trial data showing
TMG does not exceed 10% of the parent compound residue level in leafy
vegetables and the 1.5 factor was based on metabolism data.
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 assessed chronic
dietary exposure using the same residue information and assumptions
regarding metabolites/degradates as in the acute exposure analysis.
iii. Cancer. Based on the lack of evidence of carcinogenicity in
two adequate rodent carcinogenicity studies, EPA has classified
clothianidin as ``not likely to be carcinogenic to humans.'' Therefore,
a quantitative exposure assessment to evaluate cancer risk is
unnecessary.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue and/or PCT information in the dietary assessment
for clothianidin. 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 clothianidin in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of clothianidin. 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) and
Screening Concentration in Ground Water (SCI-GROW) models, the
estimated drinking water concentrations (EDWCs) of clothianidin for
surface water are estimated to be 7.29 parts per billion (ppb) for
acute exposures and 1.35 ppb for chronic exposures. For ground water,
the EDWC is estimated to be 5.88 ppb.
[[Page 65025]]
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. The water concentration value
of 7.29 ppb was used to assess the contribution to drinking water for
the acute dietary assessment. For chronic dietary risk assessment, the
water concentration of value 5.88 ppb was used.
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).
Clothianidin is currently registered for use on turf. Residential
handler exposure is not expected from the currently registered or
proposed uses of clothianidin since these products are to be applied by
commercial applicators. Adult short- and intermediate-term
postapplication exposures were assessed for dermal exposures from
commercial applications (via granular push-type spreaders), dermal
post-application contact and golfer postapplication contact. For
toddlers, short- and intermediate-term postapplication incidental oral
(hand-to-mouth and soil ingestion) and dermal risks were assessed for
exposure to treated turf.
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.''
Clothianidin is a member of the neonicotinoid class of pesticides
and is a metabolite of another neonicotinoid, thiamethoxam. Structural
similarities or common effects do not constitute a common mechanism of
toxicity. Evidence is needed to establish that the chemicals operate by
the same, or essentially the same sequence of major biochemical events
(EPA, 2002). Although clothianidin and thiamethoxam bind selectively to
insect nicotinic acetylcholine receptors (nAChR), the specific binding
site(s)/receptor(s) for clothianidin, thiamethoxam, and the other
neonicotinoids are unknown at this time. Additionally, the commonality
of the binding activity itself is uncertain, as preliminary evidence
suggests that clothianidin operates by direct competitive inhibition,
while thiamethoxam is a non competitive inhibitor. Furthermore, even if
future research shows that neonicotinoids share a common binding
activity to a specific site on insect nicotinic acetylcholine
receptors, there is not necessarily a relationship between this
pesticidal action and a mechanism of toxicity in mammals. Structural
variations between the insect and mammalian nAChRs produce quantitative
differences in the binding affinity of the neonicotinoids towards these
receptors, which, in turn, confers the notably greater selective
toxicity of this class towards insects, including aphids and
leafhoppers, compared to mammals. While the insecticidal action of the
neonicotinoids is neurotoxic, the most sensitive regulatory endpoint
for clothianidin is based on unrelated effects in mammals, including
changes in body and thymus weights, delays in sexual maturation, and
still births. Additionally, the most sensitive toxicological effect in
mammals differs across the neonicotinoids (e.g., testicular tubular
atrophy with thiamethoxam; mineralized particles in thyroid colloid
with imidaclopid). Thus, there is currently no evidence to indicate
that neonicotinoids share common mechanisms of toxicity, and EPA is not
following a cumulative risk approach based on a common mechanism of
toxicity for the neonicotinoids. 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
the policy statements concerning common mechanism determinations and
procedures for cumulating effects from substances found to have a
common mechanism released by EPA's Office of Pesticide Programs on
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 Food Quality
Protection Act (FQPA) safety factor (SF). In applying this provision,
EPA either retains the default value of 10X, or uses a different
additional SF when reliable data available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity. The toxicology data for
clothianidin provide no indication of increased quantitative or
qualitative susceptibility, as compared to adults, of rat and rabbit
fetuses to in utero exposure in developmental studies. However,
increased quantitative susceptibility was observed in both the
developmental neurotoxicity and rat multi-generation reproduction
studies. In the developmental neurotoxicity study, offspring toxicity
(decreased body weight gains, motor activity and acoustic startle
response) was seen at a lower dose than that which caused maternal
toxicity. In the 2-generation rat reproduction study, offspring
toxicity (decreased body weight gains, delayed sexual maturation in
males, decreased absolute thymus weights in F1 pups of both sexes and
an increase in stillbirths in both generations) was seen at a dose
lower than that which caused parental toxicity.
3. Conclusion. In the final rule published in the Federal Register
of February 6, 2008 (73 FR 6851) (FRL-8346-9), EPA had previously
determined that the FQPA SF for clothianidin should be retained at 10X
because EPA had required the submission of a developmental
immunotoxicity study to address the combination of evidence of
decreased absolute and adjusted organ weights of the thymus and spleen
in multiple studies in the clothianidin data base, and evidence showing
that juvenile rats in the 2-generation reproduction study appear to be
more susceptible to these potential immunotoxic effects. In the absence
of a developmental immunotoxicity study EPA concluded that there was
sufficient uncertainty regarding immunotoxic effects in the young that
the 10X FQPA factor should be retained as a database uncertainty
factor. Since that determination, EPA has received and reviewed an
acceptable/guideline developmental immunotoxicity study, which
demonstrated no treatment-related effects. Taking the results of this
study into account as well as the rest of the data on clothianidin, EPA
has determined that reliable data show the safety of infants and
children would be adequately protected if the FQPA SF for clothianidin
were reduced to 1X. That decision is based on the following findings:
i. The toxicity database for clothianidin is complete. As noted,
the prior data gap concerning developmental immunotoxicity has been
addressed by the submission of an acceptable developmental
immunotoxicity study.
[[Page 65026]]
ii. A rat developmental neurotoxicity study is available and shows
evidence of increased quantitative susceptibility of offspring.
However, EPA considers the degree of concern for the developmental
neurotoxicity study to be low for prenatal and postnatal toxicity
because the NOAEL and LOAEL were well characterized, and the doses and
endpoints selected for risk assessment are protective of the observed
susceptibility; therefore, there are no residual concerns regarding
effects in the young.
iii. While the rat multi-generation reproduction study showed
evidence of increased quantitative susceptibility of offspring compared
to adults, the degree of concern is low because the study NOAEL and
LOAEL have been selected for risk assessment purposes for relevant
exposure routes and durations. In addition, the potential immunotoxic
effects observed in the study have been further characterized with the
submission of a developmental immunotoxicity study that showed no
evidence of susceptibility. As a result, there are no concerns or
residual uncertainties for prenatal and postnatal toxicity after
establishing toxicity endpoints and traditional UFs to be used in the
risk assessment for clothianidin.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on assumptions that were judged to be highly conservative and health-
protective for all durations and population subgroups, including
tolerance-level residues, adjustment factors from metabolite data,
empirical processing factors, and 100 PCT for all commodities.
Additionally, EPA made conservative (protective) assumptions in the
ground and surface water modeling used to assess exposure to
clothianidin in drinking water. EPA used similarly conservative
assumptions to assess postapplication exposure of children and adults
as well as incidental oral exposure of toddlers. These assessments will
not underestimate the exposure and risks posed by clothianidin.
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-, intermediate-, 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
clothianidin will occupy 23% of the aPAD for children 1 to 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
clothianidin from food and water will utilize 19% of the cPAD for
children 1 to 2 years old, the population group receiving the greatest
exposure. Based on the explanation in Unit III.C.3., regarding
residential use patterns, chronic residential exposure to residues of
clothianidin is not expected.
3. Short- and intermediate-term risk. 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).
Clothianidin is currently registered for use on turf that could
result in short- and intermediate-term residential exposure and the
Agency has determined that it is appropriate to aggregate chronic
exposure through food and water with short- and intermediate-term
residential exposures to clothianidin. Using the exposure assumptions
described in this unit for short- and intermediate-term exposures, EPA
has concluded the combined short- and intermediate-term food, water,
and residential exposures aggregated result in aggregate MOEs of
greater than 380 for all population subgroups. As the aggregate MOEs
are greater than 100 (the LOC) for all population subgroups, including
infants and children, short- and intermediate-term aggregate exposures
to clothianidin are not of concern to EPA.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in mice and rats at doses that were judged
to be adequate to assess the carcinogenic potential, clothianidin was
classified as ``not likely to be carcinogenic to humans,'' and 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 clothianidin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate liquid chromatography/mass spectrometry/mass spectrometry
(LC/MS/MS) enforcement methodology is available to enforce the
tolerance expression for both plant and animal commodities and has been
forwarded to the Food and Drug Administration for inclusion in the
Pesticide Analytical Manual (PAM), Volume II. 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
In order to harmonize with Canadian maximum residue limits (MRLs)
on potato tubers at 0.3 ppm; potato chips at 0.6 ppm and potato
granules/flakes at 1.5 ppm, EPA has recommended the following
tolerances: Vegetable, tuberous and corm, subgroup 1C (which includes
potato) at 0.3 ppm; potato, chips at 0.6 ppm; and potato granules/
flakes at 1.5 ppm. Additionally, Canada is currently reviewing a
petition to establish a tolerance in or on the stone fruit (including
peaches) crop group at 0.8 ppm. A tolerance on peach at 0.80 ppm is
being recommended by EPA to harmonize with Canada's recommended stone
fruit MRL. There are currently no Canadian MRLs established for
residues of clothianidin in or on other commodities associated with
these petitions. There are currently no Codex or Mexican MRLs
established for residues of clothianidin in or on commodities
associated with these petitions.
C. Revisions to Petitioned-For Tolerances
EPA has revised the proposed tolerance levels for foliar
applications of clothianidin on the following commodities: Leafy
vegetable, crop group 4 from 3.5 ppm to 3.0 ppm; brassica vegetable,
crop group 5 from 3.0 ppm to 1.9 ppm; fruiting vegetable, crop group 8
from 0.25 to 0.20 ppm; and cucurbit vegetable, crop group 9 from 0.05
to 0.06 ppm. EPA has also revised the proposed tolerance levels in or
on
[[Page 65027]]
soybean, seed from 0.03 ppm to 0.02 ppm; root vegetable, except sugar
beet, subgroup 1B from 0.60 ppm to 0.8 ppm; bulb vegetable group 3-07
from 0.2 ppm to 0.45 ppm; and wheat, straw from 0.04 ppm to 0.05 ppm;
and has revised the proposed tolerance amendment for cotton, undelinted
seed (the preferred commodity definition for cotton, seed) from 0.25 to
0.20. EPA revised the tolerance levels based on analysis of the residue
field trial data using the Agency's Tolerance Spreadsheet in accordance
with the Agency's Guidance for Setting Pesticide Tolerances Based on
Field Trial Data.
The Agency has also revised tolerances in order to harmonize U.S.
MRLs with currently established or pending Canadian MRLs for peach from
0.7 ppm to 0.80 ppm; and for tuberous and corm vegetable, group 1C
(based on the a seed piece treatment which results in the highest
residue) from 0.2 ppm to 0.3 ppm. Additionally, the Agency has
established a tolerance in or on potato, chips at 0.6 ppm; and has
increased a currently-established tolerance in or on potato, granules/
flakes from 0.08 to 1.5 ppm to harmonize with Canadian MRLs on the
commodities.
EPA has also determined that individual tolerances are not
necessary for several petitioned-for commodities. A request to increase
an existing potato tolerance from 0.05 ppm to 0.6 ppm is not necessary
because potato is superseded by inclusion in the tuberous and corm
subgroup 1C; thus, the existing potato tolerance is being deleted. A
proposed tolerance on vegetable, leafy greens, except brassica,
subgroup 4A at 1.1 ppm is not necessary, as the subgroup tolerance is
superseded by inclusion in the leafy vegetable except brassica, group
4. Separate tolerances in or on soybean, hulls; soybean, meal; and
soybean, oil are not required because adequate soybean processing data
indicate that quantifiable residues are unlikely to occur in soybean
processed fractions; thus, only a soybean seed tolerance is being
established. Separate tolerances in or on cotton, meal; cotton, hulls;
and cotton, refined oil are not required because residues were reduced
in these commodities; therefore, the existing cotton, undelinted seed
(the preferred commodity term for cotton, seed) and cotton, gin
byproducts (the preferred commodity term for cotton, gin trash)
tolerances are being amended to reflect increased tolerances of 0.20
and 4.5 ppm, respectively. Finally, adequate processing data indicate
that separate tolerances in or on tomato, paste at 0.08 ppm and tomato,
puree at 0.07 ppm are not necessary; therefore, only a fruiting
vegetable group 8 (including tomato) tolerance is required.
EPA has reviewed the available wheat, corn and sorghum data and has
determined that sufficient data are available to establish the
following group tolerances: Grain, cereal, forage, fodder and straw,
group 16, except rice, forage at 0.35 ppm; grain, cereal, forage,
fodder and straw, group 16, except rice, hay at 0.07 ppm; grain,
cereal, forage, fodder and straw, group 16, except rice, stover at 0.1
ppm; grain, cereal, forage, fodder and straw, group 16, except rice,
straw at 0.05 ppm. The registrant petitioned for a crop group tolerance
on the Cereal Grains Group (Crop Group 15) but only petitioned for
individual tolerances in or on wheat, forage (at 0.35 ppm); wheat, hay
(at 0.07 ppm); and wheat, straw (at 0.04); and not tolerances on the
crop group covering Forage, Fodder, and Straw of the Cereal Grains
(Crop Group 16). However, EPA has determined that tolerances for group
16 are appropriate because the petitioned-for wheat feed item
tolerances when considered in conjunction with the existing feed item
tolerances for corn and sorghum satisfied the requirements for
establishment of Crop Group 16 tolerances. The Crop Group 16 tolerances
are being limited like the Crop Group 15 tolerance to exclude rice.
Additionally, the following established tolerances are being deleted
because they are superseded by inclusion in group 16: corn, field,
forage at 0.10 ppm; corn, field, stover at 0.10 ppm; corn, pop, stover
at 0.10 ppm; corn, sweet, forage at 0.10 ppm; corn, sweet, stover at
0.10; sorghum, forage and stover at 0.01 ppm; and grain, cereal,
forage, fodder and straw, group 16 at 0.02 ppm (a tolerance resulting
from indirect/inadvertent residues of clothianidin). Finally,
tolerances of clothianidin in or on corn, field grain at 0.01 ppm;
corn, pop, grain at 0.01 ppm; corn, sweet, kernel plus cob with husk
removed at 0.01 ppm; and sorghum, grain at 0.01 ppm are being deleted
because they are being superseded by inclusion in the grain, cereal,
group 15.
Additionally, a final rule published in the Federal Register of
December 7, 2007 (72 FR 69150) (FRL-8343-1) that amended the existing
bulb vegetable group 3 by adding several commodities; the updated group
was renamed the bulb vegetable group 3-07. This rule, as well as the
earlier May 23, 2007 proposed rule (72 FR 28920) (FRL-8126-1) stated
that, for existing petitions for which a Notice of Filing had been
published, the Agency would attempt to conform these petitions to the
rule. Therefore, consistent with this rule, EPA has assessed for and is
establishing a tolerance for group 3-07 instead of the proposed bulb
vegetable group 3.
Finally, EPA has revised the tolerance expression to clarify (1)
that, as provided in FFDCA section 408(a)(3), the tolerance covers
metabolites and degradates of clothianidin not specifically mentioned;
and (2) that compliance with the specified tolerance levels is to be
determined by measuring only the specific compounds mentioned in the
tolerance expression.
V. Conclusion
Therefore, tolerances are established for residues of clothianidin,
(E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-nitroguanidine, in
or on almond, hulls at 1.5 ppm; berry, low-growing, subgroup 13-07H,
except strawberry at 0.01 ppm; fig at 0.05; grain, cereal, forage,
fodder and straw, group 16, except rice, forage at 0.35 ppm; grain,
cereal, forage, fodder and straw, group 16, except rice, hay at 0.07
ppm; grain, cereal, forage, fodder and straw, group 16, except rice,
stover at 0.1 ppm; grain, cereal, forage, fodder and straw, group 16,
except rice, straw at 0.05 ppm; grain, cereal, group 15, except rice at
0.01 ppm; nut, tree, group 14 at 0.01 ppm; peach at 0.80 ppm;
pomegranate at 0.20 ppm; potato, chips at 0.6 ppm; soybean, seed at
0.02 ppm; vegetable, brassica, leafy, group 5 at 1.9 ppm; vegetable,
bulb, group 3-07 at 0.45 ppm; vegetable, cucurbit, group 9 at 0.06 ppm;
vegetable, fruiting, group 8 at 0.20 ppm; vegetable, leafy, except
brassica, group 4 at 3.0 ppm; vegetable, root, except sugar beet,
subgroup 1B at 0.8 ppm; and vegetable, tuberous and corm, subgroup 1C
at 0.3 ppm. Additionally, tolerances are amended for residues of
clothianidin in or on cotton, gin byproducts from 0.01 ppm to 4.5 ppm;
cotton, undelinted seed from 0.01 ppm to 0.20 ppm; and potato,
granules/flakes from 0.08 to 1.5 ppm. This regulation deletes a
tolerance in or on potato at 0.05 ppm; corn, field, forage at 0.10 ppm;
corn, field, grain at 0.01 ppm; corn, field, stover at 0.10 ppm; corn,
pop, grain at 0.01 ppm; corn, pop, stover at 0.10 ppm; corn, sweet,
forage at 0.10 ppm; corn, sweet, kernel plus cob with husk removed at
0.01 ppm; corn, sweet, stover at 0.10 ppm; and sorghum, forage, grain,
stover at 0.01 ppm. Finally, this regulation deletes a tolerance for
indirect/inadvertent residues of clothianidin in or on grain, cereal,
forage, fodder and straw, group 16 at 0.02 ppm. Also, the introductory
text in 40 CFR 180.586(a), (b) and (d), which includes the tolerance
expression, are revised.

VI. Statutory and Executive Order Reviews
This final rule establishes tolerances 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 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).
