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 trifloxystrobin
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with trifloxystrobin 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.
Trifloxystrobin exhibits very low
toxicity following single oral, dermal
and inhalation exposures. It is a strong
dermal sensitizer. In repeated dose tests
in rats, the liver is the target organ for
trifloxystrobin; toxicity is induced
following oral and dermal exposure for
28 days. There is no evidence of
increased susceptibility following
prenatal exposure to rats and rabbits
and postnatal exposures to rats.
Trifloxystrobin was determined not to
be carcinogenic in mice or rats
following long-term dietary
VerDate Mar<15>2010

Jkt 226001
administration. Trifloxystrobin is
positive for mutagenicity in Chinese
Hamster V79 cells, albeit at cytotoxic
dose levels. However, trifloxystrobin is
negative in the remaining mutagenicity
studies. Specific information on the
studies received and the nature of the
adverse effects caused by trifloxystrobin
as well as the no-observed-adverseeffect-level (NOAEL) and the lowestobserved-adverse-effect-level (LOAEL)
from the toxicity studies are discussed
in the final rule published in the
Federal Register of June 11, 2010 (75 FR
33190) (FRL–8829–2), and at https://
www.regulations.gov in the document
‘‘Trifloxystrobin. Human Health Risk
Assessment for a Section 3 Petition
Proposing Increased Tolerances for
Residues in/on Field, Sweet and Pop
Corn,’’ pp. 17–21 in docket ID number
EPA–HQ–OPP–2009–0278.
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 trifloxystrobin used for
human risk assessment is discussed in
Unit III.B. of the final rule published in
the Federal Register of June 11, 2010.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to trifloxystrobin, EPA
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
42655
considered exposure under the
petitioned-for tolerances as well as all
existing trifloxystrobin tolerances in 40
CFR 180.555. EPA assessed dietary
exposures from trifloxystrobin 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 trifloxystrobin. In estimating acute
dietary exposure for females 13–49
years old, EPA conducted an analysis
using the Dietary Exposure Evaluation
Model (DEEM\TM\ 7.81), which used
food consumption information from the
United States Department of Agriculture
(USDA) 1994–1996 and 1998
Nationwide Continuing Surveys of Food
Intake by Individuals (CSFII). As to
residue levels in food, EPA used
tolerance level residues. EPA assumed
all commodities with established or
proposed tolerances were treated with
trifloxystrobin.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 1994–1996 and 1998
CSFII. As to residue levels in food, EPA
used tolerance level residues for all
commodities with the exception of
apples, oranges and grapes. For these
commodities EPA used anticipated
residues from field residue trials. EPA
assumed all commodities with
established or proposed tolerances were
treated with trifloxystrobin.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that trifloxystrobin 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 percent
crop treated (PCT) information. Section
408(b)(2)(E) of FFDCA authorizes EPA
to use available data and information on
the anticipated residue levels of
pesticide residues in food and the actual
levels of pesticide residues that have
been measured in food. If EPA relies on
such information, EPA must require
pursuant to FFDCA section 408(f)(1)
that data be provided 5 years after the
tolerance is established, modified, or
left in effect, demonstrating that the
levels in food are not above the levels
anticipated. For the present action, EPA
will issue such data call-ins as are
required by FFDCA section 408(b)(2)(E)
and authorized under FFDCA section
408(f)(1). Data will be required to be
submitted no later than 5 years from the
date of issuance of these tolerances.

2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for trifloxystrobin in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
trifloxystrobin. 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 Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS), and Screening
Concentration in Ground Water (SCI–
GROW) models, the estimated drinking
water concentrations (EDWCs) of
trifloxystrobin plus its major
degradation product, CGA–321113 for
the proposed artichoke, globe use are
estimated to be 47.98 parts per billion
(ppb) and 47.31 ppb for surface water
for acute and chronic exposures,
respectively. Modeled estimates of
drinking water concentrations were
directly entered into the dietary
exposure model.
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).
Trifloxystrobin is currently registered
for the following uses that could result
in residential exposures: Ornamentals
and turfgrass. EPA assessed residential
exposure under the following exposure
scenarios: Adult post-application
dermal exposure; and children’s postapplication dermal and/or hand to
mouth exposure. Further information
regarding EPA standard assumptions
and generic inputs for residential
exposures may be found at https://www.
epa.gov/pesticides/trac/science/
trac6a05.
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 trifloxystrobin to
share a common mechanism of toxicity
with any other substances, and
trifloxystrobin does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that trifloxystrobin does not
VerDate Mar<15>2010
16:01 Jul 19, 2012
Jkt 226001
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s Web site at
https://www.epa.gov/pesticides/
cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no indication of increased
susceptibility of rat or rabbits to
trifloxystrobin. In the prenatal
developmental study in rats, there was
no developmental toxicity at the limit
dose. In the prenatal developmental
study in rabbits, developmental toxicity
was seen at a dose that was higher than
the dose that caused maternal toxicity.
In the 2-generation reproduction study,
there was no offspring toxicity at the
highest dose tested.
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 database is complete except for
an immunotoxicity study and an
inhalation study. Although an
immunotoxicity study is needed, the
entire trifloxystrobin toxicity database
was examined and there was no
indication that this chemical directly
targets the immune system. EPA does
not believe that conducting an
immunotoxicity study will result in a
dose less than the points of departure
already used in this risk assessment and
an additional database uncertainty
factor (UF) for potential immunotoxicity
does not need to be applied. Regarding
the requirement for an inhalation
toxicity study, the Agency has increased
its focus on the uncertainties associated
with route-to-route extrapolation (i.e.,
the use of oral toxicity studies for
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
inhalation risk assessment) and is
presently requiring inhalation toxicity
studies more frequently. Although an
inhalation toxicity study is now
required for trifloxystrobin based on
OPP’s current weight of the evidence
(WOE) approach, residential inhalation
exposure is not anticipated; therefore,
there are no uncertainties with respect
to residential inhalation exposures to
trifloxystrobin and no need to retain an
additional database uncertainty factor
for this safety finding.
ii. There is no indication that
trifloxystrobin is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity. A waiver for a subchronic
neurotoxicity study has been granted.
There is no evidence of neurotoxicity in
subchronic and chronic toxicity studies
(rats, dogs, mice), in developmental
toxicity studies (rats, rabbits), or in a
reproductive toxicity study (rats). There
is no concern for neurotoxicity for
trifloxystrobin based on the available
database, limited findings in an acute
neurotoxicity study, and lack of
neurotoxicity in other fungicides of the
strobilurin class.
iii. There is no evidence that
trifloxystrobin results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2-generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The acute dietary exposure assessment
was unrefined, and the chronic dietary
exposure assessment was partially
refined, assuming 100 PCT and
tolerance-level residues for all
commodities except for apples, grapes,
and oranges where the average field trial
residues were used. By using these
screening-level assessments with minor
refinement, actual exposures/risks from
residues in food will not be
underestimated. EPA made conservative
(protective) assumptions in the ground
and surface water modeling used to
assess exposure to trifloxystrobin 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 trifloxystrobin.
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
E:\FR\FM\20JYR1.SGM
20JYR1
tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 140 / Friday, July 20, 2012 / Rules and Regulations
risks, EPA calculates the lifetime
probability of acquiring cancer given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the appropriate
PODs to ensure that an adequate MOE
exists.
1. Acute risk. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
trifloxystrobin will occupy 1.9% of the
aPAD for females 13–49 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 trifloxystrobin
from food and water will utilize 64% 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
residues of trifloxystrobin 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).
Trifloxystrobin is currently registered
for uses that 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 trifloxystrobin. 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 1,100 for
adults (dermal residential + dietary food
and drinking water exposures); 650 for
children 1–2 years (dermal residential +
dietary food and drinking water
exposures); and 130 for children 1–2
years (incidental oral residential +
dietary food and drinking water
exposures). Because EPA’s level of
concern for trifloxystrobin is a MOE of
100 or less, 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).
Trifloxystrobin is not expected to pose
an intermediate-term risk based on a
short soil half-life (approximately 2
days).

5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
chemical name 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
trifloxystrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(gas chromatography with nitrogen
phosphorus detection (GC/NPD),
Method AG–659A and liquid
chromatography with tandem mass
spectrometry detection (LC/MS/MS),
Method No. 200177) 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 trifloxystrobin on artichoke, globe.
Therefore, international harmonization
is not an issue.
V. Conclusion
Therefore, a tolerance is established
for residues of trifloxystrobin,
[benzeneacetic acid, (E,E)-a(methoxyimino)-2-[[[[1-[3(trifluoromethyl)phenyl]ethylidene]
amino]oxy]methyl]-methyl ester], in or
on artichoke, globe at 1.0 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

ACTION: Final rule.
AGENCY:
This final rule establishes
data collection standards necessary to
implement aspects of section 1302 of
the Patient Protection and Affordable
Care Act (Affordable Care Act), which
directs the Secretary of Health and
Human Services to define essential
health benefits. This final rule outlines
the data on applicable plans to be
collected from certain issuers to support
the definition of essential health
benefits. This final rule also establishes
a process for the recognition of
accrediting entities for purposes of
certification of qualified health plans.
DATES: Effective Date: These regulations
are effective on August 20, 2012.
FOR FURTHER INFORMATION CONTACT:

SUPPLEMENTARY INFORMATION:
SUMMARY:
Executive Summary
Beginning in 2014, all nongrandfathered health plans in the
individual and small group market, and
other plans will cover the essential
health benefits (EHB), as defined by the
Secretary of Health and Human Services
(the Secretary). The Affordable Care Act
directs that the EHB reflect the scope of
benefits covered by a typical employer
plan and cover at least the following 10
general categories of items and services:
Ambulatory patient services; emergency
services; hospitalization; maternity and
newborn care; mental health and
substance use disorder services,
including behavioral health treatment;
prescription drugs; rehabilitative and
habilitative services and devices;
laboratory services; preventive and
wellness services and chronic disease
management; and pediatric services,
including oral and vision care. EHB will
promote predictability for consumers
PO 00000
Frm 00038
Fmt 4700
Sfmt 4700
who purchase coverage in these
markets, facilitate comparison across
health plans, and ensure that individual
and small group subscribers have the
same access to the same scope of
benefits provided under a typical
employer plan.
This final rule includes data reporting
standards for health plans that represent
potential State-specific benchmark
plans. Specifically, the final rule
establishes that issuers of the largest
three small group market products in
each state report information on covered
benefits.
In addition, this rule establishes the
first phase of a two-phased approach for
recognizing accrediting entities to
implement the standards established
under the Affordable Care Act for
qualified health plans (QHPs) to be
accredited on the basis of local
performance by an accrediting entity
recognized by the Secretary on a
timeline established by the Exchange
and addresses some data sharing and
performance requirements of the
recognized accrediting entities. In phase
one, the National Committee for Quality
Assurance (NCQA) and URAC are
recognized as accrediting entities on an
interim basis. In phase two, a criteriabased review process will be adopted
through future rulemaking.
I. Background
Section 2707 of the Public Health
Service Act, as added by section 1201 of
the Affordable Care Act, directs that, for
plan years beginning on or after January
1, 2014, health insurance issuers
offering non-grandfathered plans in the
individual or small group market ensure
such coverage includes EHB as
described in section 1302(a) of the
Affordable Care Act. Section 1302 of the
Affordable Care Act provides for the
establishment of EHB, to be defined by
the Secretary. The law also directs that
EHB reflect the scope of benefits
covered by a typical employer plan and
cover at least the 10 general categories
of items and services previously listed.
Section 1302(b)(4) of the Affordable
Care Act further establishes that the
Secretary define EHB such that it:
• Sets an appropriate balance among
the 10 general categories;
• Does not discriminate based on age,
disability, or expected length of life;
• Takes into account the health care
needs of diverse segments of the
population; and
• Does not allow denials of essential
benefits based on age, life expectancy,
disability, or degree of medical
dependency and quality of life.
Section 1302(b)(4) of the Affordable
Care Act further directs the Secretary to

II. Summary of Petitioned-For Tolerance
In the Federal Register of April 4, 2012 (77 FR 20334) (FRL-9340-
4), EPA issued a notice pursuant to FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing the filing of a pesticide petition (PP 1F7845)
by Bayer CropScience, 2 TW Alexander Dr., Research Triangle Park, NC
27709. The petition requested that 40 CFR 180.555 be amended by
establishing tolerances for residues of the fungicide trifloxystrobin,
[benzeneacetic acid, (E,E)-[alpha]-(methoxyimino)-2-[[[[1-[3-
(trifluoromethyl)phenyl]ethylidene] amino]oxy]methyl]-methyl ester], in
or on artichoke, globe at 1.0 parts per million (ppm). That notice
referenced a summary of the petition prepared by Bayer CropScience, the
registrant, which is available in the docket, https://www.regulations.gov.
[[Page 42655]]
There were no comments received in response to the notice of
filing.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue * *
*.''
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for trifloxystrobin including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with trifloxystrobin
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.
Trifloxystrobin exhibits very low toxicity following single oral,
dermal and inhalation exposures. It is a strong dermal sensitizer. In
repeated dose tests in rats, the liver is the target organ for
trifloxystrobin; toxicity is induced following oral and dermal exposure
for 28 days. There is no evidence of increased susceptibility following
prenatal exposure to rats and rabbits and postnatal exposures to rats.
Trifloxystrobin was determined not to be carcinogenic in mice or rats
following long-term dietary administration. Trifloxystrobin is positive
for mutagenicity in Chinese Hamster V79 cells, albeit at cytotoxic dose
levels. However, trifloxystrobin is negative in the remaining
mutagenicity studies. Specific information on the studies received and
the nature of the adverse effects caused by trifloxystrobin as well as
the no-observed-adverse-effect-level (NOAEL) and the lowest-observed-
adverse-effect-level (LOAEL) from the toxicity studies are discussed in
the final rule published in the Federal Register of June 11, 2010 (75
FR 33190) (FRL-8829-2), and at https://www.regulations.gov in the
document ``Trifloxystrobin. Human Health Risk Assessment for a Section
3 Petition Proposing Increased Tolerances for Residues in/on Field,
Sweet and Pop Corn,'' pp. 17-21 in docket ID number EPA-HQ-OPP-2009-
0278.
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 trifloxystrobin used for human risk assessment is
discussed in Unit III.B. of the final rule published in the Federal
Register of June 11, 2010.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to trifloxystrobin, EPA considered exposure under the
petitioned-for tolerances as well as all existing trifloxystrobin
tolerances in 40 CFR 180.555. EPA assessed dietary exposures from
trifloxystrobin 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 trifloxystrobin. In estimating acute dietary exposure for females
13-49 years old, EPA conducted an analysis using the Dietary Exposure
Evaluation Model (DEEM\TM\ 7.81), which used food consumption
information from the United States Department of Agriculture (USDA)
1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by
Individuals (CSFII). As to residue levels in food, EPA used tolerance
level residues. EPA assumed all commodities with established or
proposed tolerances were treated with trifloxystrobin.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 CSFII. As to residue levels in food, EPA used tolerance level
residues for all commodities with the exception of apples, oranges and
grapes. For these commodities EPA used anticipated residues from field
residue trials. EPA assumed all commodities with established or
proposed tolerances were treated with trifloxystrobin.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that trifloxystrobin 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 percent crop treated (PCT) information.
Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and
information on the anticipated residue levels of pesticide residues in
food and the actual levels of pesticide residues that have been
measured in food. If EPA relies on such information, EPA must require
pursuant to FFDCA section 408(f)(1) that data be provided 5 years after
the tolerance is established, modified, or left in effect,
demonstrating that the levels in food are not above the levels
anticipated. For the present action, EPA will issue such data call-ins
as are required by FFDCA section 408(b)(2)(E) and authorized under
FFDCA section 408(f)(1). Data will be required to be submitted no later
than 5 years from the date of issuance of these tolerances.
[[Page 42656]]
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for trifloxystrobin in drinking water. These simulation
models take into account data on the physical, chemical, and fate/
transport characteristics of trifloxystrobin. 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 Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS), and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated drinking water concentrations (EDWCs) of
trifloxystrobin plus its major degradation product, CGA-321113 for the
proposed artichoke, globe use are estimated to be 47.98 parts per
billion (ppb) and 47.31 ppb for surface water for acute and chronic
exposures, respectively. Modeled estimates of drinking water
concentrations were directly entered into the dietary exposure model.
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).
Trifloxystrobin is currently registered for the following uses that
could result in residential exposures: Ornamentals and turfgrass. EPA
assessed residential exposure under the following exposure scenarios:
Adult post-application dermal exposure; and children's post-application
dermal and/or hand to mouth exposure. Further information regarding EPA
standard assumptions and generic inputs for residential exposures may
be found at https://www.epa.gov/pesticides/trac/science/trac6a05.
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 trifloxystrobin to share a common mechanism of
toxicity with any other substances, and trifloxystrobin does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
trifloxystrobin does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no indication of
increased susceptibility of rat or rabbits to trifloxystrobin. In the
prenatal developmental study in rats, there was no developmental
toxicity at the limit dose. In the prenatal developmental study in
rabbits, developmental toxicity was seen at a dose that was higher than
the dose that caused maternal toxicity. In the 2-generation
reproduction study, there was no offspring toxicity at the highest dose
tested.
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 database is complete except for an immunotoxicity study and
an inhalation study. Although an immunotoxicity study is needed, the
entire trifloxystrobin toxicity database was examined and there was no
indication that this chemical directly targets the immune system. EPA
does not believe that conducting an immunotoxicity study will result in
a dose less than the points of departure already used in this risk
assessment and an additional database uncertainty factor (UF) for
potential immunotoxicity does not need to be applied. Regarding the
requirement for an inhalation toxicity study, the Agency has increased
its focus on the uncertainties associated with route-to-route
extrapolation (i.e., the use of oral toxicity studies for inhalation
risk assessment) and is presently requiring inhalation toxicity studies
more frequently. Although an inhalation toxicity study is now required
for trifloxystrobin based on OPP's current weight of the evidence (WOE)
approach, residential inhalation exposure is not anticipated;
therefore, there are no uncertainties with respect to residential
inhalation exposures to trifloxystrobin and no need to retain an
additional database uncertainty factor for this safety finding.
ii. There is no indication that trifloxystrobin is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity. A waiver for a
subchronic neurotoxicity study has been granted. There is no evidence
of neurotoxicity in subchronic and chronic toxicity studies (rats,
dogs, mice), in developmental toxicity studies (rats, rabbits), or in a
reproductive toxicity study (rats). There is no concern for
neurotoxicity for trifloxystrobin based on the available database,
limited findings in an acute neurotoxicity study, and lack of
neurotoxicity in other fungicides of the strobilurin class.
iii. There is no evidence that trifloxystrobin results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The acute dietary exposure assessment was unrefined, and the
chronic dietary exposure assessment was partially refined, assuming 100
PCT and tolerance-level residues for all commodities except for apples,
grapes, and oranges where the average field trial residues were used.
By using these screening-level assessments with minor refinement,
actual exposures/risks from residues in food will not be
underestimated. EPA made conservative (protective) assumptions in the
ground and surface water modeling used to assess exposure to
trifloxystrobin 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 trifloxystrobin.
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
[[Page 42657]]
risks, EPA calculates the lifetime probability of acquiring cancer
given the estimated aggregate exposure. Short-, intermediate-, and
chronic-term risks are evaluated by comparing the estimated aggregate
food, water, and residential exposure to the appropriate PODs to ensure
that an adequate MOE exists.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to trifloxystrobin will occupy 1.9% of the aPAD for females 13-49 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
trifloxystrobin from food and water will utilize 64% 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 residues of
trifloxystrobin 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).
Trifloxystrobin is currently registered for uses that 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 trifloxystrobin. 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 1,100 for adults (dermal
residential + dietary food and drinking water exposures); 650 for
children 1-2 years (dermal residential + dietary food and drinking
water exposures); and 130 for children 1-2 years (incidental oral
residential + dietary food and drinking water exposures). Because EPA's
level of concern for trifloxystrobin is a MOE of 100 or less, 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). Trifloxystrobin is not expected to pose an intermediate-term
risk based on a short soil half-life (approximately 2 days).
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, chemical name 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 trifloxystrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography with nitrogen
phosphorus detection (GC/NPD), Method AG-659A and liquid chromatography
with tandem mass spectrometry detection (LC/MS/MS), Method No. 200177)
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 trifloxystrobin on
artichoke, globe. Therefore, international harmonization is not an
issue.
V. Conclusion
Therefore, a tolerance is established for residues of
trifloxystrobin, [benzeneacetic acid, (E,E)-[alpha]-(methoxyimino)-2-
[[[[1-[3-(trifluoromethyl)phenyl]ethylidene] amino]oxy]methyl]-methyl
ester], in or on artichoke, globe at 1.0 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
[[Page 42658]]
Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
