II. Summary of Petitioned-For
Tolerance
In the Federal Register of July 6, 2011
(76 FR 39358) (FRL–8875–6) and of July
20, 2011 (76 FR 43233) (FRL–8880–1),
EPA issued documents pursuant to
FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing the filing of
pesticide petitions (PP 1F7841) by
Valent U.S.A. Corporation, 1600 Riviera
Ave., Suite 200, Walnut Creek, CA
94596 and PP 1E7850 by IR–4, 500
College Road East, Suite 201W,
Princeton, NJ 08540. The petitions
requested that 40 CFR part 180 be
amended by establishing tolerances for
residues of the fungicide
fenpyrazamine, S-allyl 5-amino-2isopropyl-4-(2-methylphenyl)-3-oxo-2,3dihydropyrazole-1-carbothioate, in or
on: Almond at 0.02 parts per million
(ppm); almond, hulls at 1.5 ppm;
lettuce, head at 2.5 ppm; lettuce, leaf at
2.5 ppm; small fruit vine climbing
subgroup, except fuzzy kiwi fruit, crop
subgroup 13–07F at 3.5 ppm; grape,
juice at 7.0 ppm; grape, raisins at 4.5
ppm; low growing berry subgroup 13–
07G at 3.0 ppm (PP 1F7841); pistachio
at 0.02 ppm; Caneberry subgroup 13–
07A at 7.0 ppm; Bushberry subgroup
13–07B at 7.0 ppm; and ginseng at 0.80
ppm (PP 1E7850). Those documents
referenced a summary of the petitions
prepared by Valent U.S.A. Corporation,
the registrant, which are available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notices of filing.
Based upon review of the data
supporting the petition, EPA has
determined that the tolerances should
be based upon parent fenpyrazamine

III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue * * * .’’ Consistent
with FFDCA section 408(b)(2)(D), and
the factors specified in FFDCA section
408(b)(2)(D), EPA has reviewed the
available scientific data and other
relevant information in support of this
action. EPA has sufficient data to assess
the hazards of and to make a
determination on aggregate exposure for
fenpyrazamine including exposure
resulting from the tolerances established
by this action. EPA’s assessment of
exposures and risks associated with
fenpyrazamine follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its validity,
completeness, and reliability as well as
the relationship of the results of the
studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children.
The principal toxicological findings
for fenpyrazamine in repeated dose
studies in rodents, rabbits, and dogs
were reduced bodyweights/bodyweight
weight gains. In addition, thyroid
follicular cell hypertrophy was observed
in rats in the subchronic, chronic/
carcinogenicity and reproduction
toxicity (parental animals only) studies.
Although increased liver weights,
hepatocellular hypertrophy, and
alterations in hematology and clinical
chemistry parameters were observed in
several studies, they were not
considered to be toxicologically relevant
since the magnitude of the changes was
VerDate Mar<15>2010
13:26 Mar 05, 2013
Jkt 229001
within normal variability. The liver
alterations were therefore considered
adaptive rather than adverse effects.
There was no evidence of increased
susceptibility of developing organisms
after in utero or post-natal exposure to
fenpyrazamine in the developmental
toxicity studies (rats and rabbits) or the
multi-generation reproduction toxicity
study. In both the rat and rabbit
developmental studies, maternal effects
(decreased body weight) occurred at
doses lower than or equal to those
eliciting developmental effects
(decreased fetal weight, skeletal
variations in rats and late abortions and
premature deliveries in rabbits). Since
the late abortions and premature
deliveries occurred at doses higher than
the maternal LOAEL, this finding is not
considered to be indicative of
susceptibility. In the multi-generation
reproduction toxicity study, thyroid
toxicity was observed in parental
animals at the same dose eliciting
decreased body weights in the offspring.
Reproductive effects manifested as
decreases in implantations and
increases in postimplantation loss
occurred at a dose level approximately
4x higher than the parental and
offspring LOAELs.
The only potential sign of
neurotoxicity was a decrease in total
motor activity and total number of
rearings observed in the acute
neurotoxicity study in rats. However,
given that the liver is the target tissue,
these effects may be nonspecific effects
secondary to general toxicity. These
effects were not observed in the
subchronic neurotoxicity or any other
studies in the database.
In a 28-day dermal toxicity study, no
hazard was identified at the limit dose
1,000 milligrams/kilogram/day (mg/kg/
day). Similarly, an immunotoxicity
study in rats did not indicate that the
immune system is a target for
fenpyrazamine toxicity.
Although an increase in the incidence
of hepatocellular and thyroid follicular
carcinomas was noted in the chronic/
carcinogenicity study in rats, the
concern for these findings is low based
on the following weight of evidence
considerations:
1. The marginal increases occurred
only at the high dose;
2. There was no reduction in the
latency period (i.e., tumors were seen
only at the terminal sacrifice); and
3. The incidences were only slightly
outside the historical control range of
the testing laboratories.
In addition, no neoplastic lesions
attributable to treatment were observed
in the carcinogenicity study in mice and
PO 00000
Frm 00026
Fmt 4700
Sfmt 4700
no indication of mutagenicity was noted
in the mutagenicity battery. Based on
this evidence, in accordance with the
Agency’s 2005 Guidelines for Cancer
Risk Assessment, EPA classified
fenpyrazamine as ‘‘Not Likely to be
Carcinogenic to Humans’’.
Specific information on the studies
received and the nature of the adverse
effects caused by fenpyrazamine 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://

13–07B, Caneberry Subgroup 13–07A,
Ginseng, and Pistachio’’ in docket ID
number EPA–HQ–OPP–2011–0357.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/

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

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to fenpyrazamine, EPA
considered exposure under the
petitioned-for tolerances in 40 CFR 180.
EPA assessed dietary exposures from
fenpyrazamine in food as follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
are performed for a food-use pesticide,
if a toxicological study has indicated the
possibility of an effect of concern
occurring as a result of a 1-day or single
exposure. Such effects were identified
for fenpyrazamine. In estimating acute
dietary exposure, EPA used food
consumption information from the 2003
to 2008 United States Department of
Agriculture (USDA) National Health and
Nutrition Examination Survey, What We
Eat in America, (NHANES/WWEIA). For
residue levels in food, EPA assumed 100
percent crop treated (PCT) and tolerance
level residues of parent fenpyrazamine
plus the maximum residue of S–2188–
DC (expressed as parent fenpyrazamine)
observed in the crop field trials for the
proposed uses.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the 2003 to 2008 United States
Department of Agriculture (USDA)
National Health and Nutrition
Examination Survey, What We Eat in
America, (NHANES/WWEIA). For
residue levels in food, EPA assumed 100
PCT and tolerance level residues of
parent fenpyrazamine plus the
maximum residue of S–2188–DC
(expressed as parent fenpyrazamine)
observed in the crop field trials for the
proposed uses.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that fenpyrazamine does not
pose a cancer risk to humans. Therefore,
VerDate Mar<15>2010
13:26 Mar 05, 2013
Jkt 229001
a dietary exposure assessment for the
purpose of assessing cancer risk is
unnecessary.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue or PCT information
in the dietary assessment for
fenpyrazamine. Tolerance level residues
and 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 fenpyrazamine in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
fenpyrazamine. 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 Tier 1 FQPA Index
Reservoir Screening Tool (FIRST v.
1.1.1, released March 26, 2008) for
surface water and the Screening
Concentration in Ground Water (SCI–
GROW) model for ground water, the
estimated drinking water concentrations
(EDWCs) of fenpyrazamine for acute
exposures are estimated to be 213.5
parts per billion (ppb) for surface water
and 1.31 ppb for ground water. The
chronic exposures are estimated to be
72.5 ppb for surface water and 1.31 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 213.5 ppb was
used to assess the contribution to
drinking water. For chronic dietary risk
assessment, the water concentration of
value 72.5 ppb was used to assess the
contribution to drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700
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).
Fenpyrazamine 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 fenpyrazamine to share a
common mechanism of toxicity with
any other substances, and
fenpyrazamine does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that fenpyrazamine does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
E:\FR\FM\06MRR1.SGM
06MRR1
14464
Federal Register / Vol. 78, No. 44 / Wednesday, March 6, 2013 / Rules and Regulations
pmangrum on DSK3VPTVN1PROD with RULES
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no evidence of increased preand/or postnatal susceptibility based on
the results of the rat and rabbit prenatal
developmental toxicity studies, and the
rat 2-generation reproductive toxicity
study.
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
fenpyrazamine is complete.
ii. There is no evidence of increased
pre- and/or postnatal susceptibility for
fenpyrazamine.
iii. There is no residual uncertainty in
the exposure database for
fenpyrazamine with respect to dietary
(food and water) exposure. The dietary
food exposure assessments were
performed based on 100 PCT and
tolerance-level residues of parent
fenpyrazamine plus the maximum
reside of the metabolite S–2188–DC,
empirical concentration factors and
default processing factors. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to
fenpyrazamine in drinking water. These
assessments will not underestimate the
exposure and risks posed by
fenpyrazamine.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate exposure
estimates to the aPAD and chronic
population-adjusted dose (cPAD). For
linear cancer risks, EPA calculates the
lifetime probability of acquiring cancer
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
appropriate PODs to ensure that an
adequate MOE exists. Since there are no
residential uses proposed for
fenpyrazamine, the aggregate risks are
equal to the dietary and drinking water
assessments.
1. Acute risk. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
VerDate Mar<15>2010
13:26 Mar 05, 2013
Jkt 229001
fenpyrazamine will occupy 9.2% of the
aPAD for children 1–2 years old, the
population group receiving the greatest
exposure.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to fenpyrazamine
from food and water will utilize 7.3% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure.
3. Short-term and intermediate-term
risk. Short-term and intermediate-term
aggregate exposure takes into account
short-term or intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Fenpyrazamine is not registered for any
use patterns that would result in shortterm or intermediate-term residential
exposure. Short-term and intermediateterm risk is assessed based on shortterm or intermediate-term residential
exposure plus chronic dietary exposure.
Because there is no short-term or
intermediate-term residential exposure
and chronic dietary exposure has
already been assessed under the
appropriately protective cPAD (which is
at least as protective as the POD used to
assess short-term risk), no further
assessment of short-term or
intermediate-term risk is necessary, and
EPA relies on the chronic dietary risk
assessment for evaluating short-term
and intermediate-term risk for
fenpyrazamine.
4. Aggregate cancer risk for U.S.
population. Based on the results of two
adequate rodent carcinogenicity studies,
fenpyrazamine 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
fenpyrazamine residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Parent fenpyrazamine only is the
residue of concern for tolerance
enforcement purposes. Valent U.S.A.
Corporation has submitted the results of
an independent laboratory validation
(ILV) by liquid chromatography and
mass spectrometry (LC/MS/MS),
Method RM–45C–1, titled
‘‘Determination of S–2188 and S–2188–
DC in crops’’. The method is considered
adequate for enforcement of tolerances
in plant commodities.

B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
Fenpyrazamine is a new active

C. Revisions to Petitioned-For
Tolerances
The Agency established parent
fenpyrazamine only as the residue of
concern for tolerance enforcement in
plants and tolerances were
recommended accordingly. These differ
from the tolerances proposed by the
registrant, which are based on residues
of parent fenpyrazamine and the
metabolite S–2188–DC expressed as
fenpyrazamine. In addition, the
Organization for the Economical
Cooperation and Development (OECD)
calculation procedures were used to
estimate the tolerances and based on
these procedures, the Agency has
determined that the lettuce, head
tolerance should be lowered from 2.0 to
1.5 ppm; lettuce, leaf from 2.5 ppm to
2 ppm; Caneberry subgroup 13–07A
from 7.0 ppm to 5 ppm; Bushberry
subgroup 13–07B from 7.0 ppm to 5
ppm; small fruit vine climbing subgroup
except fuzzy kiwi fruit, subgroup 13–
07F from 3.5 ppm to 3 ppm; and grape,
juice from 7.0 ppm to 4 ppm. Finally,
the submitted grape processing data
indicate that residues of parent
fenpyrazamine only concentrate in
raisins at 1.1x. Therefore, the
concentration factor for raisin is not

V. Conclusion
Therefore, tolerances are established
for residues of fenpyrazamine, S-allyl 5amino-2-isopropyl-4-(2-methylphenyl)3-oxo-2,3-dihydropyrazole-1carbothioate, in or on Almond at 0.02
ppm; almond, hulls at 1.5 ppm;
pistachio at 0.02 ppm; lettuce, head at
1.5 ppm; lettuce, leaf at 2 ppm;
Caneberry subgroup 13–07A at 5 ppm;
Bushberry subgroup 13–07B at 5 ppm;
small fruit vine climbing subgroup
except fuzzy kiwi fruit, subgroup 13–
07F at 3 ppm; grape, juice at 4 ppm; low
growing berry subgroup 13–07G at 3
ppm; and ginseng at 0.7 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This final rule does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of FFDCA section 408(n)(4). As such,
VerDate Mar<15>2010
13:26 Mar 05, 2013
Jkt 229001
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

II. Summary of Petitioned-For Tolerance
In the Federal Register of July 6, 2011 (76 FR 39358) (FRL-8875-6)
and of July 20, 2011 (76 FR 43233) (FRL-8880-1), EPA issued documents
pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing
the filing of pesticide petitions (PP 1F7841) by Valent U.S.A.
Corporation, 1600 Riviera Ave., Suite 200, Walnut Creek, CA 94596 and
PP 1E7850 by IR-4, 500 College Road East, Suite 201W, Princeton, NJ
08540. The petitions requested that 40 CFR part 180 be amended by
establishing tolerances for residues of the fungicide fenpyrazamine, S-
allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-2,3-dihydropyrazole-
1-carbothioate, in or on: Almond at 0.02 parts per million (ppm);
almond, hulls at 1.5 ppm; lettuce, head at 2.5 ppm; lettuce, leaf at
2.5 ppm; small fruit vine climbing subgroup, except fuzzy kiwi fruit,
crop subgroup 13-07F at 3.5 ppm; grape, juice at 7.0 ppm; grape,
raisins at 4.5 ppm; low growing berry subgroup 13-07G at 3.0 ppm (PP
1F7841); pistachio at 0.02 ppm; Caneberry subgroup 13-07A at 7.0 ppm;
Bushberry subgroup 13-07B at 7.0 ppm; and ginseng at 0.80 ppm (PP
1E7850). Those documents referenced a summary of the petitions prepared
by Valent U.S.A. Corporation, the registrant, which are available in
the docket, https://www.regulations.gov. There were no comments received
in response to the notices of filing.
Based upon review of the data supporting the petition, EPA has
determined that the tolerances should be based upon parent
fenpyrazamine only, has revised the tolerance levels for several
commodities, and determined a tolerance is not needed for raisins. The
reason for these changes is explained in Unit IV.D.
[[Page 14462]]
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue * *
* .'' Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for fenpyrazamine including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with fenpyrazamine
follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children.
The principal toxicological findings for fenpyrazamine in repeated
dose studies in rodents, rabbits, and dogs were reduced bodyweights/
bodyweight weight gains. In addition, thyroid follicular cell
hypertrophy was observed in rats in the subchronic, chronic/
carcinogenicity and reproduction toxicity (parental animals only)
studies. Although increased liver weights, hepatocellular hypertrophy,
and alterations in hematology and clinical chemistry parameters were
observed in several studies, they were not considered to be
toxicologically relevant since the magnitude of the changes was within
normal variability. The liver alterations were therefore considered
adaptive rather than adverse effects.
There was no evidence of increased susceptibility of developing
organisms after in utero or post-natal exposure to fenpyrazamine in the
developmental toxicity studies (rats and rabbits) or the multi-
generation reproduction toxicity study. In both the rat and rabbit
developmental studies, maternal effects (decreased body weight)
occurred at doses lower than or equal to those eliciting developmental
effects (decreased fetal weight, skeletal variations in rats and late
abortions and premature deliveries in rabbits). Since the late
abortions and premature deliveries occurred at doses higher than the
maternal LOAEL, this finding is not considered to be indicative of
susceptibility. In the multi-generation reproduction toxicity study,
thyroid toxicity was observed in parental animals at the same dose
eliciting decreased body weights in the offspring. Reproductive effects
manifested as decreases in implantations and increases in
postimplantation loss occurred at a dose level approximately 4x higher
than the parental and offspring LOAELs.
The only potential sign of neurotoxicity was a decrease in total
motor activity and total number of rearings observed in the acute
neurotoxicity study in rats. However, given that the liver is the
target tissue, these effects may be nonspecific effects secondary to
general toxicity. These effects were not observed in the subchronic
neurotoxicity or any other studies in the database.
In a 28-day dermal toxicity study, no hazard was identified at the
limit dose 1,000 milligrams/kilogram/day (mg/kg/day). Similarly, an
immunotoxicity study in rats did not indicate that the immune system is
a target for fenpyrazamine toxicity.
Although an increase in the incidence of hepatocellular and thyroid
follicular carcinomas was noted in the chronic/carcinogenicity study in
rats, the concern for these findings is low based on the following
weight of evidence considerations:
1. The marginal increases occurred only at the high dose;
2. There was no reduction in the latency period (i.e., tumors were
seen only at the terminal sacrifice); and
3. The incidences were only slightly outside the historical control
range of the testing laboratories.
In addition, no neoplastic lesions attributable to treatment were
observed in the carcinogenicity study in mice and no indication of
mutagenicity was noted in the mutagenicity battery. Based on this
evidence, in accordance with the Agency's 2005 Guidelines for Cancer
Risk Assessment, EPA classified fenpyrazamine as ``Not Likely to be
Carcinogenic to Humans''.
Specific information on the studies received and the nature of the
adverse effects caused by fenpyrazamine 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 section 4.5.4 in the document ``Human Health
Risk Assessment for the Section 3 Registration and Establishment of
Tolerances on Almond, Small Fruit Climbing Subgroup 13-07F, Head and
Leaf Lettuce, and Low Growing Berry Subgroup 13-07G, Bushberry Subgroup
13-07B, Caneberry Subgroup 13-07A, Ginseng, and Pistachio'' in docket
ID number EPA-HQ-OPP-2011-0357.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for fenpyrazamine used for
human risk assessment is shown in the following Table.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fenpyrazamine, EPA considered exposure under the
petitioned-for tolerances in 40 CFR 180. EPA assessed dietary exposures
from fenpyrazamine in food as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure. Such effects were identified
for fenpyrazamine. In estimating acute dietary exposure, EPA used food
consumption information from the 2003 to 2008 United States Department
of Agriculture (USDA) National Health and Nutrition Examination Survey,
What We Eat in America, (NHANES/WWEIA). For residue levels in food, EPA
assumed 100 percent crop treated (PCT) and tolerance level residues of
parent fenpyrazamine plus the maximum residue of S-2188-DC (expressed
as parent fenpyrazamine) observed in the crop field trials for the
proposed uses.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the 2003 to 2008
United States Department of Agriculture (USDA) National Health and
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA).
For residue levels in food, EPA assumed 100 PCT and tolerance level
residues of parent fenpyrazamine plus the maximum residue of S-2188-DC
(expressed as parent fenpyrazamine) observed in the crop field trials
for the proposed uses.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that fenpyrazamine does not pose a cancer risk to humans.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue or PCT information in the dietary assessment for
fenpyrazamine. Tolerance level residues and 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 fenpyrazamine in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of fenpyrazamine. 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 Tier 1 FQPA Index Reservoir Screening Tool (FIRST v.
1.1.1, released March 26, 2008) for surface water and the Screening
Concentration in Ground Water (SCI-GROW) model for ground water, the
estimated drinking water concentrations (EDWCs) of fenpyrazamine for
acute exposures are estimated to be 213.5 parts per billion (ppb) for
surface water and 1.31 ppb for ground water. The chronic exposures are
estimated to be 72.5 ppb for surface water and 1.31 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 213.5 ppb was used to
assess the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 72.5 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). Fenpyrazamine 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
fenpyrazamine to share a common mechanism of toxicity with any other
substances, and fenpyrazamine does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that fenpyrazamine 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

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
[[Page 14464]]
and children. This additional margin of safety is commonly referred to
as the FQPA Safety Factor (SF). In applying this provision, EPA either
retains the default value of 10X, or uses a different additional safety
factor when reliable data available to EPA support the choice of a
different factor.
2. Prenatal and postnatal sensitivity. There is no evidence of
increased pre- and/or postnatal susceptibility based on the results of
the rat and rabbit prenatal developmental toxicity studies, and the rat
2-generation reproductive toxicity study.
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 fenpyrazamine is complete.
ii. There is no evidence of increased pre- and/or postnatal
susceptibility for fenpyrazamine.
iii. There is no residual uncertainty in the exposure database for
fenpyrazamine with respect to dietary (food and water) exposure. The
dietary food exposure assessments were performed based on 100 PCT and
tolerance-level residues of parent fenpyrazamine plus the maximum
reside of the metabolite S-2188-DC, empirical concentration factors and
default processing factors. EPA made conservative (protective)
assumptions in the ground and surface water modeling used to assess
exposure to fenpyrazamine in drinking water. These assessments will not
underestimate the exposure and risks posed by fenpyrazamine.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
aPAD and chronic population-adjusted dose (cPAD). For linear cancer
risks, EPA calculates the lifetime probability of acquiring cancer
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 appropriate PODs
to ensure that an adequate MOE exists. Since there are no residential
uses proposed for fenpyrazamine, the aggregate risks are equal to the
dietary and drinking water assessments.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to fenpyrazamine will occupy 9.2% of the aPAD for children 1-2 years
old, the population group receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
fenpyrazamine from food and water will utilize 7.3% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure.
3. Short-term and intermediate-term risk. Short-term and
intermediate-term aggregate exposure takes into account short-term or
intermediate-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Fenpyrazamine
is not registered for any use patterns that would result in short-term
or intermediate-term residential exposure. Short-term and intermediate-
term risk is assessed based on short-term or intermediate-term
residential exposure plus chronic dietary exposure. Because there is no
short-term or intermediate-term residential exposure and chronic
dietary exposure has already been assessed under the appropriately
protective cPAD (which is at least as protective as the POD used to
assess short-term risk), no further assessment of short-term or
intermediate-term risk is necessary, and EPA relies on the chronic
dietary risk assessment for evaluating short-term and intermediate-term
risk for fenpyrazamine.
4. Aggregate cancer risk for U.S. population. Based on the results
of two adequate rodent carcinogenicity studies, fenpyrazamine 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 fenpyrazamine residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Parent fenpyrazamine only is the residue of concern for tolerance
enforcement purposes. Valent U.S.A. Corporation has submitted the
results of an independent laboratory validation (ILV) by liquid
chromatography and mass spectrometry (LC/MS/MS), Method RM-45C-1,
titled ``Determination of S-2188 and S-2188-DC in crops''. The method
is considered adequate for enforcement of tolerances in plant
commodities.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
Fenpyrazamine is a new active ingredient and MRLs have not been
established by Codex, Canada, or Mexico for the commodities proposed
for registration in the US.
C. Revisions to Petitioned-For Tolerances
The Agency established parent fenpyrazamine only as the residue of
concern for tolerance enforcement in plants and tolerances were
recommended accordingly. These differ from the tolerances proposed by
the registrant, which are based on residues of parent fenpyrazamine and
the metabolite S-2188-DC expressed as fenpyrazamine. In addition, the
Organization for the Economical Cooperation and Development (OECD)
calculation procedures were used to estimate the tolerances and based
on these procedures, the Agency has determined that the lettuce, head
tolerance should be lowered from 2.0 to 1.5 ppm; lettuce, leaf from 2.5
ppm to 2 ppm; Caneberry subgroup 13-07A from 7.0 ppm to 5 ppm;
Bushberry subgroup 13-07B from 7.0 ppm to 5 ppm; small fruit vine
climbing subgroup except fuzzy kiwi fruit, subgroup 13-07F from 3.5 ppm
to 3 ppm; and grape, juice from 7.0 ppm to 4 ppm. Finally, the
submitted grape processing data indicate that residues of parent
fenpyrazamine only concentrate in raisins at 1.1x. Therefore, the
concentration factor for raisin is not
[[Page 14465]]
high enough to justify the need of a separate tolerance for raisins.
V. Conclusion
Therefore, tolerances are established for residues of
fenpyrazamine, S-allyl 5-amino-2-isopropyl-4-(2-methylphenyl)-3-oxo-
2,3-dihydropyrazole-1-carbothioate, in or on Almond at 0.02 ppm;
almond, hulls at 1.5 ppm; pistachio at 0.02 ppm; lettuce, head at 1.5
ppm; lettuce, leaf at 2 ppm; Caneberry subgroup 13-07A at 5 ppm;
Bushberry subgroup 13-07B at 5 ppm; small fruit vine climbing subgroup
except fuzzy kiwi fruit, subgroup 13-07F at 3 ppm; grape, juice at 4
ppm; low growing berry subgroup 13-07G at 3 ppm; and ginseng at 0.7
ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA section 408(d)
in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this final rule has
been exempted from review under Executive Order 12866, this final rule
is not subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This final rule does not contain
any information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
