Further information
• In the case that Solstice® FS is inhaled, person(s) should be
immediately removed and exposed to fresh air; if breathing is difficult, person(s) should seek medical attention;
• Eye wash and quick drench facilities should be available. In
case of ocular exposure, person(s) should immediately flush the
eyes, including under the eyelids, with water for 15 minutes; should
frostbite occur, affected areas should be rinsed with lukewarm
water, and medical attention should be sought if irritation develops
or persists;
• In the case of dermal exposure, the SDS recommends that person(s) should immediately wash the affected area with water and remove all contaminated clothing to avoid irritation; should frostbite
occur, bathe (do not rub) the affected area with lukewarm, no hot,
water. If water is not available, cover the affected area with a clean
soft cloth; and medical attention should be sought if irritation develops or persists.
• Although unlikely, in case of ingestion of Solstice® FS, the person(s) should drink a cup of water, if fully conscious, and consult a
physician immediately;
• Manufacturing space should be equipped with engineering controls, specifically an adequate exhaust ventilation system, to effectively mitigate potential occupational exposure;
• Employees responsible for chemical processing should wear
the appropriate personal protective equipment (PPE), such as protective gloves, tightly sealed goggles, protective work clothing, and
suitable respiratory protection in case of accidental release or insufficient ventilation;
• All spills should be cleaned up immediately in accordance with
good industrial hygiene practices;\
• Training for safe handling procedures should be provided to all
employees that would be likely to handle containers of the agent or
extinguishing units filled with the agent;

II. Summary of Petitioned-for
Tolerances
In the Federal Register of December
17, 2014 (79 FR 75107) (FRL–9918–90),
EPA issued a document pursuant to
FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide petition (PP 3F8224) by Valent
U.S.A., Corporation,1600 Riviera Ave.,
Suite 200, Walnut Creek, California,
94596. The petition requested that 40
CFR 180 be amended by establishing
tolerances for residues of the fungicide
mandestrobin, (2-[(2,5dimethylphenoxy)methyl]-a-methoxyN-methyl-benzeneacetamide), in or on
small fruit vine climbing except fuzzy
kiwifruit crop subgroup 13–07F, fruit at
5 parts per million (ppm), juice at 7
ppm, and dried fruit at 10 ppm; low
growing berry subgroup 13–07G, fruit at
3 ppm; and rapeseed crop subgroup
20A, seed at 0.6 ppm. That document
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. There were no
comments received in response to the
notice of filing.
Based upon review of the data
supporting the petition, EPA lowered
the requested tolerance levels for grape,
raisin. Tolerances for juice and dried
fruit are not required. At this time, EPA
is not granting a tolerance for rapeseed
crop group 20A. The reason for these
changes is 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
PO 00000
Frm 00041
Fmt 4700
Sfmt 4700
70039
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 mandestrobin
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with mandestrobin as
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 main target organs for
mandestrobin toxicity in all mammalian
species tested are the liver and gall
bladder with effects ranging from
hepatocyte hypertrophy and increased
liver weight (usually considered not
adverse in the absence of corroborative
hepatic enzyme changes or
histopathology) to centrilobular
degeneration, hepatocyte and bile duct
pigmentation, periductular
inflammation and gall stones. Dogs were
more sensitive to the adverse liver
effects than rats; mice showed only nonadverse liver effects.
Thyroid effects were observed in rats
(increased weight, follicular cell
hypertrophy, decreased serum hormone
levels) at higher doses than early signs
of liver effects suggesting that effects in
the thyroid may be secondary to liver
effects.
Gonadal effects were observed at
higher doses than the liver effects, and
were more evident in dogs (immature
prostate and/or testes, low sperm count,
immature ovaries, decrease uterus
weight) but equivocal and/or not
adverse in rats. Gonadal effects did not
affect the reproductive capacity of rats.
No developmental effects were
observed in rats or rabbits, and no
adverse reproductive, immunotoxic, or
neurotoxic effects were observed in any
of the studies. No adverse effects were
E:\FR\FM\11OCR1.SGM

seen in a route-specific dermal toxicity
study. Mutagenicity studies were
negative. There is no evidence of
carcinogenicity because there was no
increase in tumor incidence in rat and
mouse long-term studies. The Agency
classified mandestrobin as ‘‘not likely to
be a human carcinogen’’.
Specific information on the studies
received and the nature of the toxic
effects caused by mandestrobin 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://

EPA–HQ–OPP–2014–0285.
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 mandestrobin used for

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to mandestrobin, EPA
considered exposure from the
petitioned-for tolerances only as there
are no existing mandestrobin tolerances.
EPA assessed dietary exposures from
mandestrobin in food as follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
VerDate Sep<11>2014
14:37 Oct 07, 2016
Jkt 241001
are performed for a food-use pesticide,
if a toxicological study has indicated the
possibility of an effect of concern
occurring as a result of a 1-day or single
exposure. No such effects were
identified in the toxicological studies
for mandestrobin; therefore, a
quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
PO 00000
Frm 00042
Fmt 4700
Sfmt 4700
from the U.S. Department of
Agriculture’s (USDA’s) National Health
and Nutrition Examination Survey,
What We Eat in America, (NHANES/
WWEIA). As to residue levels in food,
EPA assumed tolerance-level residues,
100 percent crops treated (PCT), and
default processing factors for all
proposed commodities.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that mandestrobin does not
E:\FR\FM\11OCR1.SGM
11OCR1
ehiers on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 81, No. 196 / Tuesday, October 11, 2016 / Rules and Regulations
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
mandestrobin. 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 mandestrobin in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
mandestrobin. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www2.epa.gov/
pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide.
Based on the First Index Reservoir
Screening Tool (FIRST) and Pesticide
Root Zone Model Ground Water (PRZM
GW), the estimated drinking water
concentrations (EDWCs) of
mandestrobin for chronic exposures for
non-cancer assessments are estimated to
be 38 parts per billion (ppb) for surface
water and 3.9 ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 38 ppb was
used to assess the contribution to
drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Mandestrobin is currently proposed for
use on turf at golf courses, sod farms,
recreational/athletic fields, and
residential/commercial lawns. EPA
assessed residential exposure using the
following scenarios. For residential
handlers, the worst-case scenario was
determined to be short-term inhalation
exposures to adults from mixing,
loading, and applying mandestrobin to
turf. For post-application exposures, the
worst-case scenario was determined to
be short-term post-application
incidental oral exposure to children
from hand-to-mouth activities on turf.

standard assumptions and generic
inputs for residential exposures may be

standard-operating-proceduresresidential-pesticide.
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 mandestrobin to
share a common mechanism of toxicity
with any other substances, and
mandestrobin does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that mandestrobin 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://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no evidence of sensitivity/
susceptibility in the offspring following
mandestrobin exposure, including
developmental toxicity studies in rats
and rabbits, and a 2-generation
reproductive study in rats. Although
pup weights were decreased in the rat
reproductive study, this change was
observed at the same dose as maternal
liver effects, which included periportal/
bile duct pigment, periductular
inflammatory cell infiltration, and bile
duct proliferation.
3. Conclusion. EPA has determined
that reliable data show the safety of
infants and children would be
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
70041
adequately protected if the FQPA SF
were reduced to 1X. That decision is
based on the following findings:
i. The toxicity database for the
mandestrobin tolerances being
established is complete.
ii. There is no indication that
mandestrobin is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is no evidence that
mandestrobin results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2-generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100 PCT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to mandestrobin
in drinking water. EPA used similarly
conservative assumptions to assess postapplication exposure of children as well
as incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by mandestrobin.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate exposure
estimates to the acute PAD (aPAD) and
chronic PAD (cPAD). For linear cancer
risks, EPA calculates the lifetime
probability of acquiring cancer given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the appropriate
PODs to ensure that an adequate MOE
exists.
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, mandestrobin is not
expected to pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to mandestrobin
from food and water will utilize 2.6% of
the cPAD for children 1–2 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
E:\FR\FM\11OCR1.SGM
11OCR1
70042
Federal Register / Vol. 81, No. 196 / Tuesday, October 11, 2016 / Rules and Regulations
residues of mandestrobin is not
expected.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water
(considered to be a background
exposure level). Mandestrobin could
result in short-term residential
exposure, and the Agency has
determined that it is appropriate to
aggregate chronic exposure through food
and water with short-term residential
exposures to mandestrobin.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 19,000 for adults and 2,900 for
children 1–2 years old. Because EPA’s
level of concern for mandestrobin is a
MOE of 100 or below, these MOEs are
not of concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Since the short-and intermediate-term
PODs are the same and short-term
exposure estimates are greater than their
intermediate-term counterparts, the
short-term aggregate risk assessment is
protective of the intermediate-term
aggregate exposure. Therefore a separate
intermediate-term aggregate assessment
is not necessary.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
mandestrobin is not expected to pose a
cancer risk to humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to
mandestrobin residues.

seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has not established a MRL
for mandestrobin.
C. Revisions to Petitioned-for Tolerances
Based on an analysis of residue levels
from crop field trials, EPA is
establishing a tolerance for grape, raisin
at 7 ppm, rather than the requested level
of 10 ppm. The highest average field
trial (HAFT) for grape and the
processing factor for raisins supports a
7 ppm tolerance.
The petitioner requested tolerances
for juice and dried fruit covered under
crop subgroup 13–07F, small fruit. The
available processing data for grape, the
representative commodity for subgroup
13–07F, indicates that residues in juice
will be covered by the tolerance being
established for subgroup 13–07F. At this
time, the Agency is not aware of any
dried commodities derived from crops
in subgroup 13–07F other than raisin,
for which the Agency is establishing a
separate tolerance, as indicated in the
paragraph above.
After the petitioner submitted its
petition for tolerances on subgroup 13–
07G, it withdrew its request to include
cranberry; therefore, the Agency is only
establishing tolerances for subgroup 13–
07G, except cranberry.
At this time, EPA is not establishing
a tolerance for rapeseed subgroup 20A.
The full three year freezer storage
stability data (OPPTS guideline number
860.1380) for crop field trial data are
needed to support tolerances. These
data are required since samples from
crop field trials are often stored for a
number of years prior to analysis.
Therefore, it is a requirement to ensure
that the residues that are found multiple
years later are actually representative of
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
the residues that would be found on the
day of harvest. This ensures that the
Agency has set a tolerance high enough
to cover residues expected in/on the
commodity of interest. Accordingly,
EPA has not made a determination with
regard to this petitioned-for tolerance at
this time.
V. Conclusion
Therefore, tolerances are established
for residues of mandestrobin, 2-[(2,5dimethylphenoxy)methyl]-a-methoxyN-methylbenzeneacetamide, in or on
berry, low growing, subgroup 13–07G,
except cranberry at 3.0 ppm; fruit, small
vine climbing, except fuzzy kiwifruit,
subgroup 13–07F at 5.0 ppm; grape,
raisin at 7.0 ppm.
VI. Statutory and Executive Order
Reviews
This action establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerances in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
E:\FR\FM\11OCR1.SGM
11OCR1
Federal Register / Vol. 81, No. 196 / Tuesday, October 11, 2016 / Rules and Regulations
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

Executive Summary
This document contains: (1) A final
rule to remove Solidago albopilosa from
the Federal List of Endangered and
Threatened Plants at 50 CFR 17.12(h);
and (2) a notice of availability of a final
PDM plan.
Species addressed—Solidago
albopilosa (white-haired goldenrod) is
an upright, herbaceous plant with soft,
white hairs covering its leaves and
stems (Andreasen and Eshbaugh 1973,
p. 123). The species produces clusters of
small, fragrant, yellow flowers from
September to November. S. albopilosa is
restricted to sandstone rock shelters or
rocky ledges of a highly dissected region
known as the Red River Gorge in
Menifee, Powell, and Wolfe Counties,
KY.
The Service listed Solidago albopilosa
as a threatened species under the
Endangered Species Act of 1973, as
amended (Act; 16 U.S.C. 1531 et seq.),
primarily because of its limited range
and threats associated with ground
disturbance and trampling caused by
unlawful archaeological activities and
recreational activities such as camping,
hiking, and rock climbing (53 FR 11612,
April 7, 1988). Other identified threats
included the inadequacy of regulatory
mechanisms and minor vegetational
changes in the surrounding forest.
When the recovery plan for S.
albopilosa (white-haired goldenrod)
(Recovery Plan) was completed in 1993,
the Service knew of 90 extant
occurrences of S. albopilosa (Service
1993, p. 2), containing an estimated
45,000 stems (each individual plant can

II. Summary of Petitioned-for Tolerances
In the Federal Register of December 17, 2014 (79 FR 75107) (FRL-
9918-90), EPA issued a document pursuant to FFDCA section 408(d)(3), 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
3F8224) by Valent U.S.A., Corporation,1600 Riviera Ave., Suite 200,
Walnut Creek, California, 94596. The petition requested that 40 CFR 180
be amended by establishing tolerances for residues of the fungicide
mandestrobin, (2-[(2,5-dimethylphenoxy)methyl]-[alpha]-methoxy-N-
methyl-benzeneacetamide), in or on small fruit vine climbing except
fuzzy kiwifruit crop subgroup 13-07F, fruit at 5 parts per million
(ppm), juice at 7 ppm, and dried fruit at 10 ppm; low growing berry
subgroup 13-07G, fruit at 3 ppm; and rapeseed crop subgroup 20A, seed
at 0.6 ppm. That document 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. There were no
comments received in response to the notice of filing.
Based upon review of the data supporting the petition, EPA lowered
the requested tolerance levels for grape, raisin. Tolerances for juice
and dried fruit are not required. At this time, EPA is not granting a
tolerance for rapeseed crop group 20A. The reason for these changes is
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 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 mandestrobin including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with mandestrobin as
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 main target organs for mandestrobin toxicity in all mammalian
species tested are the liver and gall bladder with effects ranging from
hepatocyte hypertrophy and increased liver weight (usually considered
not adverse in the absence of corroborative hepatic enzyme changes or
histopathology) to centrilobular degeneration, hepatocyte and bile duct
pigmentation, periductular inflammation and gall stones. Dogs were more
sensitive to the adverse liver effects than rats; mice showed only non-
adverse liver effects.
Thyroid effects were observed in rats (increased weight, follicular
cell hypertrophy, decreased serum hormone levels) at higher doses than
early signs of liver effects suggesting that effects in the thyroid may
be secondary to liver effects.
Gonadal effects were observed at higher doses than the liver
effects, and were more evident in dogs (immature prostate and/or
testes, low sperm count, immature ovaries, decrease uterus weight) but
equivocal and/or not adverse in rats. Gonadal effects did not affect
the reproductive capacity of rats.
No developmental effects were observed in rats or rabbits, and no
adverse reproductive, immunotoxic, or neurotoxic effects were observed
in any of the studies. No adverse effects were
[[Page 70040]]
seen in a route-specific dermal toxicity study. Mutagenicity studies
were negative. There is no evidence of carcinogenicity because there
was no increase in tumor incidence in rat and mouse long-term studies.
The Agency classified mandestrobin as ``not likely to be a human
carcinogen''.
Specific information on the studies received and the nature of the
toxic effects caused by mandestrobin 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: Mandestrobin. Human Health Risk Assessment for

Sweet), Sorghum Grain (Milo), and Legume Vegetables (Crop Group 6C)
(Except Cowpea and Field Pea) at page 18 in docket ID number EPA-HQ-
OPP-2014-0285.
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 mandestrobin used for
human risk assessment is shown in Table 1.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to mandestrobin, EPA considered exposure from the petitioned-
for tolerances only as there are no existing mandestrobin tolerances.
EPA assessed dietary exposures from mandestrobin in food as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure. No such effects were
identified in the toxicological studies for mandestrobin; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the U.S. Department
of Agriculture's (USDA's) National Health and Nutrition Examination
Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in
food, EPA assumed tolerance-level residues, 100 percent crops treated
(PCT), and default processing factors for all proposed commodities.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that mandestrobin does not
[[Page 70041]]
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
mandestrobin. 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 mandestrobin in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of mandestrobin. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the First Index Reservoir Screening Tool (FIRST) and
Pesticide Root Zone Model Ground Water (PRZM GW), the estimated
drinking water concentrations (EDWCs) of mandestrobin for chronic
exposures for non-cancer assessments are estimated to be 38 parts per
billion (ppb) for surface water and 3.9 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 38 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). Mandestrobin is
currently proposed for use on turf at golf courses, sod farms,
recreational/athletic fields, and residential/commercial lawns. EPA
assessed residential exposure using the following scenarios. For
residential handlers, the worst-case scenario was determined to be
short-term inhalation exposures to adults from mixing, loading, and
applying mandestrobin to turf. For post-application exposures, the
worst-case scenario was determined to be short-term post-application
incidental oral exposure to children from hand-to-mouth activities on
turf. Further information regarding EPA standard assumptions and
generic inputs for residential exposures may be found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
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 mandestrobin to share a common mechanism of
toxicity with any other substances, and mandestrobin does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
mandestrobin 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no evidence of
sensitivity/susceptibility in the offspring following mandestrobin
exposure, including developmental toxicity studies in rats and rabbits,
and a 2-generation reproductive study in rats. Although pup weights
were decreased in the rat reproductive study, this change was observed
at the same dose as maternal liver effects, which included periportal/
bile duct pigment, periductular inflammatory cell infiltration, and
bile duct proliferation.
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 the mandestrobin tolerances being
established is complete.
ii. There is no indication that mandestrobin is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is no evidence that mandestrobin results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to mandestrobin in drinking water. EPA used
similarly conservative assumptions to assess post-application exposure
of children as well as incidental oral exposure of toddlers. These
assessments will not underestimate the exposure and risks posed by
mandestrobin.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime probability of acquiring cancer given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the appropriate PODs to ensure that an
adequate MOE exists.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effect resulting from a single oral exposure
was identified and no acute dietary endpoint was selected. Therefore,
mandestrobin is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
mandestrobin from food and water will utilize 2.6% of the cPAD for
children 1-2 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
[[Page 70042]]
residues of mandestrobin is not expected.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Mandestrobin
could result in short-term residential exposure, and the Agency has
determined that it is appropriate to aggregate chronic exposure through
food and water with short-term residential exposures to mandestrobin.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 19,000 for adults
and 2,900 for children 1-2 years old. Because EPA's level of concern
for mandestrobin is a MOE of 100 or below, these MOEs are not of
concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Since the short-and intermediate-term PODs are the same and
short-term exposure estimates are greater than their intermediate-term
counterparts, the short-term aggregate risk assessment is protective of
the intermediate-term aggregate exposure. Therefore a separate
intermediate-term aggregate assessment is not necessary.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, mandestrobin is not expected to pose a cancer risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to mandestrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (RM-48C-2A, which uses high
performance liquid chromatography with tandem mass spectrometry (HPLC/
MS-MS)) is available to enforce the tolerance expression.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for mandestrobin.
C. Revisions to Petitioned-for Tolerances
Based on an analysis of residue levels from crop field trials, EPA
is establishing a tolerance for grape, raisin at 7 ppm, rather than the
requested level of 10 ppm. The highest average field trial (HAFT) for
grape and the processing factor for raisins supports a 7 ppm tolerance.
The petitioner requested tolerances for juice and dried fruit
covered under crop subgroup 13-07F, small fruit. The available
processing data for grape, the representative commodity for subgroup
13-07F, indicates that residues in juice will be covered by the
tolerance being established for subgroup 13-07F. At this time, the
Agency is not aware of any dried commodities derived from crops in
subgroup 13-07F other than raisin, for which the Agency is establishing
a separate tolerance, as indicated in the paragraph above.
After the petitioner submitted its petition for tolerances on
subgroup 13-07G, it withdrew its request to include cranberry;
therefore, the Agency is only establishing tolerances for subgroup 13-
07G, except cranberry.
At this time, EPA is not establishing a tolerance for rapeseed
subgroup 20A. The full three year freezer storage stability data (OPPTS
guideline number 860.1380) for crop field trial data are needed to
support tolerances. These data are required since samples from crop
field trials are often stored for a number of years prior to analysis.
Therefore, it is a requirement to ensure that the residues that are
found multiple years later are actually representative of the residues
that would be found on the day of harvest. This ensures that the Agency
has set a tolerance high enough to cover residues expected in/on the
commodity of interest. Accordingly, EPA has not made a determination
with regard to this petitioned-for tolerance at this time.
V. Conclusion
Therefore, tolerances are established for residues of mandestrobin,
2-[(2,5-dimethylphenoxy)methyl]-[alpha]-methoxy-N-
methylbenzeneacetamide, in or on berry, low growing, subgroup 13-07G,
except cranberry at 3.0 ppm; fruit, small vine climbing, except fuzzy
kiwifruit, subgroup 13-07F at 5.0 ppm; grape, raisin at 7.0 ppm.
VI. Statutory and Executive Order Reviews
This action establishes tolerances under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency
[[Page 70043]]
has determined that this action will not have a substantial direct
effect on States or tribal governments, on the relationship between the
national government and the States or tribal governments, or on the
distribution of power and responsibilities among the various levels of
government or between the Federal Government and Indian tribes. Thus,
the Agency has determined that Executive Order 13132, entitled
``Federalism'' (64 FR 43255, August 10, 1999) and Executive Order
13175, entitled ``Consultation and Coordination with Indian Tribal
Governments'' (65 FR 67249, November 9, 2000) do not apply to this
action. In addition, this action does not impose any enforceable duty
or contain any unfunded mandate as described under Title II of the
Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
