Federal Register / Vol. 83, No. 121 / Friday, June 22, 2018 / Rules and Regulations
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This 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
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).

II. Summary of Petitioned-For
Tolerance
In the Federal Register of July 26,
2017 (82 FR 34664) (FRL–9963–50),
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 6F8542) by
Syngenta Crop Protection, LLC, P.O.
Box 18300, Greensboro, NC 27419. The
petition requested that 40 CFR 180.686
be amended by establishing tolerances
for residues of the fungicide
benzovindiflupyr (N-[9(dichloromethylene)-1,2,3,4-tetrahydro1,4-methanonaphthalen-5-yl]-3(difluoromethyl)-1-methyl-1H-pyrazole4-carboxamide), in or on grasses grown
for seed, forage at .15 parts per million
(ppm); grasses grown for seed, hay at 7
ppm; and grasses grown for seed, straw
at 6 ppm. That document referenced a
summary of the petition prepared by
Syngenta Crop Protection, LLC, the
registrant, which is available in the
docket, https://www.regulations.gov.
Although one commenter requested that
this petition be denied, no basis or
information was provided to support a
denial of this petition.

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 benzovindiflupyr
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with benzovindiflupyr
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 rat is the most sensitive species
tested, and the target organs of
benzovindiflupyr are the liver, thyroid,
and kidneys in rats. Hepatotoxicity was
manifested as changes in liver weights,
liver hypertrophy, and decreased
triglycerides. The kidney effects were
tubular cell pigment deposits, changes
in the tubular basophilia, and increased
urea. Enlargement and focal c-cell
hyperplasia of the thyroid were
observed. An increased incidence of cell
hypertrophy in the pituitary pars
distalis was noted in the F1 generation
males and females in the 2-generation

reproductive toxicity rat study. Mouse
studies revealed distended large
intestines, soft feces and hyperplasia of
the colon and caecum. Indications of
general malaise including decreased
body weight and food consumption,
decreased activity, decreased grip
strength, piloerection, decreased
response to stimulus, hunched posture,
gait changes and/or ataxia were reported
in the rat and mouse studies. In several
studies, females tended to be more
sensitive than males, and effects were
generally seen at lower doses with
gavage dosing than with dietary dosing.
There are no concerns for
developmental or reproductive toxicity
following benzovindiflupyr exposure.
Decreased fetal weight and ossification
in the rat developmental toxicity studies
occurred at maternally toxic doses.
There were no maternal or fetal adverse
effects in the rabbit developmental
study. In rat reproduction studies,
offspring effects (decreased body
weight, liver and pituitary effects)
occurred at doses higher than those
causing parental effects, thus there was
no quantitative increase in sensitivity in
rat pups. There were no single-dose
developmental effects identified in the
developmental toxicity studies in rats or
rabbits. Although decreases in growing
follicle counts were noted in the 2generation reproduction toxicity study,
this effect did not result in reduced
fertility in the rat. Furthermore, the
antral follicle counts at a later stage in
development were not decreased, so the
decreased growing follicle count effect
is not considered adverse.
No evidence of specific neurotoxicity
was observed in the acute oral (gavage)
and sub-chronic oral (dietary)
neurotoxicity (ACN and SCN) studies in
rats, conducted on the benzovindiflupyr
technical product. Although
benzovindiflupyr caused decreased
activity and decreased grip strength in
the neurotoxicity studies, there was no
supportive neuro-histopathology in any
study to indicate a specific neurotoxic
effect.
The mouse immunotoxicity study was
negative by the T-cell Dependent
Antigen Response (TDAR) assay in the
mouse.
No systemic effects were noted at the
limit dose of 1000 mg/kg/day in the 28day dermal rat study.
The Agency classified
benzovindiflupyr as showing
‘‘Suggestive Evidence of Carcinogenic
Potential’’ based on the presence of
granular cell tumors of the brain in male
rats only at the highest dose tested. The
Agency concluded that a non-genotoxic
mode of action for thyroid tumors
observed in male rats has been
VerDate Sep<11>2014
16:09 Jun 21, 2018
Jkt 244001
established as a result of upregulation of
uridine diphosphate
glucuronyltransferase (UDPGT),
increased clearance of T3 and T4
hormones, and increased TSH levels,
resulting in increased thyroid cell
proliferation, which progress to form
thyroid tumors. There was no evidence
of carcinogenicity in female rats or in
male or female mice. In addition, there
is no concern for mutagenicity. The
Agency has determined that using a
non-linear approach (i.e., RfD; reference
dose) will adequately account for all
chronic toxicity, including
carcinogenicity, that could result from
exposure to benzovindiflupyr.
Specific information on the studies
received and the nature of the adverse
effects caused by benzovindiflupyr as
well as the no-observed-adverse-effectlevel (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://
www.regulations.gov in the document
titled Benzovindiflupyr. Human Health
Risk Assessment for the Proposed Use
on Grasses Grown for Seeds on pages
30–36 in docket ID number EPA–HQ–
OPP–2017–0167.
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://

A summary of the toxicological
endpoints for benzovindiflupyr used for
human risk assessment is discussed in
Unit III.B. of the final rule published in
the Federal Register of November 14,
2017 (82 FR 52669) (FRL–9967–33).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to benzovindiflupyr, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing benzovindiflupyr tolerances in
40 CFR 180.686. EPA assessed dietary
exposures from benzovindiflupyr 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
benzovindiflupyr. In estimating acute
dietary exposure, EPA used 2003–2008
food consumption information 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 100
percent crop treated (PCT) and
tolerance-level residues.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used 2003–2008 food consumption
data from the USDA’s NHANES/
WWEIA. As to residue levels in food,
EPA assumed 100 PCT and tolerancelevel residues.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that a non-linear approach
(i.e., RfD) adequately accounts for all
chronic toxicity, including
carcinogenicity, that could result from
exposure to benzovindiflupyr. A
separate cancer assessment was not
performed.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue or PCT information
in the dietary assessment for
benzovindiflupyr. Tolerance level
residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for benzovindiflupyr in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
benzovindiflupyr. Further information
regarding EPA drinking water models

pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide.
Based on the Surface Water
Concentration Calculator (SWCC) model
and the Pesticide Root Zone Model
Ground Water (PRZM–GW) model, the
estimated drinking water concentrations
(EDWCs) of benzovindiflupyr for acute
exposures are estimated to be 8.41 parts
per billion (ppb) for surface water and
0.14 ppb for ground water and for
chronic exposures for non-cancer
assessments are estimated to be 5.41
ppb for surface water and 0.14 ppb for
ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
acute dietary risk assessment, the water
concentration value of 8.41 ppb was
used to assess the contribution to
drinking water. For chronic dietary risk
assessment, the water concentration of
value 5.41 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).
Benzovindiflupyr is currently
registered for the following uses that
could result in residential exposures:
Turf and ornamentals. EPA assessed
residential exposure using the following
assumptions: The residential uses of
benzovindiflupyr will result in shortterm residential handler and postapplication exposure in residential
settings. Only residential handler
inhalation and post-application
incidental oral exposure scenarios have
been quantitatively assessed since no
dermal hazard was identified.
Residential handler short-term
inhalation MOEs are well above the
LOC of 100 for all scenarios assessed
and are not of concern (inhalation MOEs
are ≥180,000). Residential postapplication (incidental oral) MOEs for
children ranged from 8,000 to 3,600,000
on the day of application, using default
input values, and are not of concern.
The residential scenarios for the
benzovindiflupyr aggregate assessments
are as follows: Adults: Inhalation
exposures from treating ornamentals
with a manually pressurized hand-wand
or backpack sprayer; children 1 to <2
years old: Post-application hand-tomouth exposures from treated turf.
These scenarios resulted in the highest
residential exposures and are
considered protective of other exposure
scenarios.

standard assumptions and generic
inputs for residential exposures may be
found at https://www2.epa.gov/pesticidescience-and-assessing-pesticide-risks/
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 benzovindiflupyr
to share a common mechanism of
toxicity with any other substances, and
benzovindiflupyr does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that benzovindiflupyr does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
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 was no evidence of quantitative
or qualitative susceptibility in fetuses or
offspring in the rat and rabbit
developmental studies or in the 2generation rat reproduction study.
Benzovindiflupyr produced effects in
rat fetuses (i.e., decreased fetal weight
and ossification) in developmental
toxicity studies at maternally toxic
doses. In the rabbit developmental
study, there were no adverse effects in
PO 00000
Frm 00060
Fmt 4700
Sfmt 4700
either the does or the fetuses at the
highest dose tested. In reproduction
studies, offspring effects occurred at
doses higher than those causing parental
effects; thus, there was no quantitative
increase in sensitivity in rat pups. The
LOAELs and NOAELs for the rat
developmental and rat reproduction
studies were clearly defined.
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
benzovindiflupyr is complete.
ii. There is no indication that
benzovindiflupyr is a neurotoxic
chemical and there is no need for a
developmental neurotoxicity study or
additional uncertainty factors (UFs) to
account for neurotoxicity.
iii. There is no evidence that
benzovindiflupyr 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
benzovindiflupyr 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 benzovindiflupyr.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate food and
water 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. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
benzovindiflupyr will occupy 43% of
the aPAD for children 1–2 years old, the

22JNR1
daltland on DSKBBV9HB2PROD with RULES
Federal Register / Vol. 83, No. 121 / Friday, June 22, 2018 / Rules and Regulations
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
benzovindiflupyr from food and water
will utilize 19% 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 benzovindiflupyr 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). Benzovindiflupyr 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 benzovindiflupyr.
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 2100 for adults and 510 for
children. Because EPA’s LOC for
benzovindiflupyr is an 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).
An intermediate-term adverse effect
was identified; however,
benzovindiflupyr is not registered for
any use patterns that would result in
intermediate-term residential exposure.
Intermediate-term risk is assessed based
on intermediate-term residential
exposure plus chronic dietary exposure.
Because there is no intermediate-term
residential exposure and chronic dietary
exposure has already been assessed
under the appropriately protective
cPAD (which is at least as protective as
the POD used to assess intermediateterm risk), no further assessment of
intermediate-term risk is necessary, and
EPA relies on the chronic dietary risk
assessment for evaluating intermediateterm risk for benzovindiflupyr.
5. Aggregate cancer risk for U.S.
population. Based on the discussion in
Unit III.A., EPA considers the chronic
aggregate risk assessment to be
protective of any aggregate cancer risk.
Based on the results of the chronic risk
assessment, which accounts for all
VerDate Sep<11>2014
16:09 Jun 21, 2018
Jkt 244001
chronic toxicity, including
carcinogenicity, EPA does not expect
any cancer risk to the U.S. population
from aggregate exposure to
benzovindiflupyr.
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
benzovindiflupyr residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An adequate analytical method is
available to enforce the proposed
tolerances for benzovindiflupyr in the
specified grass commodities. A Quick,
Easy, Cheap, Effective, Rugged, and Safe
(QuEChERS) multi-residue method
(EN15662:2009) was developed for the
determination of residues of
benzovindiflupyr via liquid
chromatography-mass spectrometry/
mass spectrometry (LC–MS/MS)
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 benzovindiflupyr.
C. Revisions to Petitioned-For
Tolerances
The registrant petitioned for the use of
benzovindiflupyr in or on grasses grown
for seed, forage at 0.15 parts per million
(ppm), grasses grown for seed, hay at 7
ppm and grasses grown for seed, straw

Frm 00061

at 6 ppm. The Agency has not
established a crop group for ‘‘grasses
grown for seed’’ or otherwise defined
what commodities are included in the
category of ‘‘grasses grown for seed’’.
The closest group tolerance to the
commodity category requested is a crop
group tolerance on grasses (i.e., ‘‘grass,
forage, fodder and hay, group 17’’),
although this group includes all grasses,
whether grown for seed or not.
Sufficient representative commodity
residue data were not submitted to
support establishing a crop group 17
tolerances; therefore, the Agency is
establishing tolerances for the
individual grasses for which residue
data were submitted: Bluegrass,
bromegrass, fescue, orchardgrass, and
ryegrass.
V. Conclusion
Therefore, tolerances are established
for residues of benzovindiflupyr,
including its metabolites and
degradates, in or on bluegrass, forage at
0.15 ppm, bluegrass, hay at 7.0 ppm,
bluegrass, straw at 6.0 ppm, bromegrass,
forage at 0.15 ppm, bromegrass, hay at
7.0 ppm, bromegrass, straw at 6.0 ppm,
fescue, forage at 0.15 ppm, fescue, hay
at 7.0 ppm, fescue, straw at 6.0 ppm,
orchardgrass, forage at 0.15 ppm,
orchardgrass, hay at 7.0 ppm,
orchardgrass, straw at 6.0 ppm, and
ryegrass, forage at 0.15 ppm, ryegrass,
hay at 7.0 ppm, and ryegrass, straw at
6.0 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); Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997); or Executive Order
13771, entitled ‘‘Reducing Regulations
and Controlling Regulatory Costs’’ (82
FR 9339, February 3, 2017). 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

Federal Register / Vol. 83, No. 121 / Friday, June 22, 2018 / Rules and Regulations
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 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
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).

II. Summary of Petitioned-For Tolerance
In the Federal Register of July 26, 2017 (82 FR 34664) (FRL-9963-
50), 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
6F8542) by Syngenta Crop Protection, LLC, P.O. Box 18300, Greensboro,
NC 27419. The petition requested that 40 CFR 180.686 be amended by
establishing tolerances for residues of the fungicide benzovindiflupyr
(N-[9-(dichloromethylene)-1,2,3,4-tetrahydro-1,4-methanonaphthalen-5-
yl]-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide), in or on
grasses grown for seed, forage at .15 parts per million (ppm); grasses
grown for seed, hay at 7 ppm; and grasses grown for seed, straw at 6
ppm. That document referenced a summary of the petition prepared by
Syngenta Crop Protection, LLC, the registrant, which is available in
the docket, https://www.regulations.gov. Although one commenter
requested that this petition be denied, no basis or information was
provided to support a denial of this petition.
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 benzovindiflupyr including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with
benzovindiflupyr 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 rat is the most sensitive species tested, and the target organs
of benzovindiflupyr are the liver, thyroid, and kidneys in rats.
Hepatotoxicity was manifested as changes in liver weights, liver
hypertrophy, and decreased triglycerides. The kidney effects were
tubular cell pigment deposits, changes in the tubular basophilia, and
increased urea. Enlargement and focal c-cell hyperplasia of the thyroid
were observed. An increased incidence of cell hypertrophy in the
pituitary pars distalis was noted in the F1 generation males and
females in the 2-generation
[[Page 29035]]
reproductive toxicity rat study. Mouse studies revealed distended large
intestines, soft feces and hyperplasia of the colon and caecum.
Indications of general malaise including decreased body weight and food
consumption, decreased activity, decreased grip strength, piloerection,
decreased response to stimulus, hunched posture, gait changes and/or
ataxia were reported in the rat and mouse studies. In several studies,
females tended to be more sensitive than males, and effects were
generally seen at lower doses with gavage dosing than with dietary
dosing.
There are no concerns for developmental or reproductive toxicity
following benzovindiflupyr exposure. Decreased fetal weight and
ossification in the rat developmental toxicity studies occurred at
maternally toxic doses. There were no maternal or fetal adverse effects
in the rabbit developmental study. In rat reproduction studies,
offspring effects (decreased body weight, liver and pituitary effects)
occurred at doses higher than those causing parental effects, thus
there was no quantitative increase in sensitivity in rat pups. There
were no single-dose developmental effects identified in the
developmental toxicity studies in rats or rabbits. Although decreases
in growing follicle counts were noted in the 2-generation reproduction
toxicity study, this effect did not result in reduced fertility in the
rat. Furthermore, the antral follicle counts at a later stage in
development were not decreased, so the decreased growing follicle count
effect is not considered adverse.
No evidence of specific neurotoxicity was observed in the acute
oral (gavage) and sub-chronic oral (dietary) neurotoxicity (ACN and
SCN) studies in rats, conducted on the benzovindiflupyr technical
product. Although benzovindiflupyr caused decreased activity and
decreased grip strength in the neurotoxicity studies, there was no
supportive neuro-histopathology in any study to indicate a specific
neurotoxic effect.
The mouse immunotoxicity study was negative by the T-cell Dependent
Antigen Response (TDAR) assay in the mouse.
No systemic effects were noted at the limit dose of 1000 mg/kg/day
in the 28-day dermal rat study.
The Agency classified benzovindiflupyr as showing ``Suggestive
Evidence of Carcinogenic Potential'' based on the presence of granular
cell tumors of the brain in male rats only at the highest dose tested.
The Agency concluded that a non-genotoxic mode of action for thyroid
tumors observed in male rats has been established as a result of
upregulation of uridine diphosphate glucuronyltransferase (UDPGT),
increased clearance of T3 and T4 hormones, and increased TSH levels,
resulting in increased thyroid cell proliferation, which progress to
form thyroid tumors. There was no evidence of carcinogenicity in female
rats or in male or female mice. In addition, there is no concern for
mutagenicity. The Agency has determined that using a non-linear
approach (i.e., RfD; reference dose) will adequately account for all
chronic toxicity, including carcinogenicity, that could result from
exposure to benzovindiflupyr.
Specific information on the studies received and the nature of the
adverse effects caused by benzovindiflupyr as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in the document titled Benzovindiflupyr. Human
Health Risk Assessment for the Proposed Use on Grasses Grown for Seeds
on pages 30-36 in docket ID number EPA-HQ-OPP-2017-0167.
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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
A summary of the toxicological endpoints for benzovindiflupyr used
for human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of November 14, 2017 (82 FR 52669)
(FRL-9967-33).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to benzovindiflupyr, EPA considered exposure under the
petitioned-for tolerances as well as all existing benzovindiflupyr
tolerances in 40 CFR 180.686. EPA assessed dietary exposures from
benzovindiflupyr 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 benzovindiflupyr. In estimating
acute dietary exposure, EPA used 2003-2008 food consumption information
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 100 percent crop treated
(PCT) and tolerance-level residues.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used 2003-2008 food consumption data from the USDA's
NHANES/WWEIA. As to residue levels in food, EPA assumed 100 PCT and
tolerance-level residues.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that a non-linear approach (i.e., RfD) adequately accounts
for all chronic toxicity, including carcinogenicity, that could result
from exposure to benzovindiflupyr. A separate cancer assessment was not
performed.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue or PCT information in the dietary assessment for
benzovindiflupyr. Tolerance level residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for benzovindiflupyr in drinking water. These simulation
models take into account data on the physical, chemical, and fate/
transport characteristics of benzovindiflupyr. Further information
regarding EPA drinking water models used in pesticide exposure
assessment
[[Page 29036]]
can be found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Surface Water Concentration Calculator (SWCC) model
and the Pesticide Root Zone Model Ground Water (PRZM-GW) model, the
estimated drinking water concentrations (EDWCs) of benzovindiflupyr for
acute exposures are estimated to be 8.41 parts per billion (ppb) for
surface water and 0.14 ppb for ground water and for chronic exposures
for non-cancer assessments are estimated to be 5.41 ppb for surface
water and 0.14 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 8.41 ppb was used to
assess the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 5.41 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).
Benzovindiflupyr is currently registered for the following uses
that could result in residential exposures: Turf and ornamentals. EPA
assessed residential exposure using the following assumptions: The
residential uses of benzovindiflupyr will result in short-term
residential handler and post-application exposure in residential
settings. Only residential handler inhalation and post-application
incidental oral exposure scenarios have been quantitatively assessed
since no dermal hazard was identified. Residential handler short-term
inhalation MOEs are well above the LOC of 100 for all scenarios
assessed and are not of concern (inhalation MOEs are >=180,000).
Residential post-application (incidental oral) MOEs for children ranged
from 8,000 to 3,600,000 on the day of application, using default input
values, and are not of concern.
The residential scenarios for the benzovindiflupyr aggregate
assessments are as follows: Adults: Inhalation exposures from treating
ornamentals with a manually pressurized hand-wand or backpack sprayer;
children 1 to <2 years old: Post-application hand-to-mouth exposures
from treated turf. These scenarios resulted in the highest residential
exposures and are considered protective of other exposure scenarios.
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 benzovindiflupyr to share a common mechanism of
toxicity with any other substances, and benzovindiflupyr does not
appear to produce a toxic metabolite produced by other substances. For
the purposes of this tolerance action, therefore, EPA has assumed that
benzovindiflupyr does not have a common mechanism of toxicity with
other substances. For information regarding EPA's efforts to determine
which chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's website at https://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 was no evidence of
quantitative or qualitative susceptibility in fetuses or offspring in
the rat and rabbit developmental studies or in the 2-generation rat
reproduction study. Benzovindiflupyr produced effects in rat fetuses
(i.e., decreased fetal weight and ossification) in developmental
toxicity studies at maternally toxic doses. In the rabbit developmental
study, there were no adverse effects in either the does or the fetuses
at the highest dose tested. In reproduction studies, offspring effects
occurred at doses higher than those causing parental effects; thus,
there was no quantitative increase in sensitivity in rat pups. The
LOAELs and NOAELs for the rat developmental and rat reproduction
studies were clearly defined.
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 benzovindiflupyr is complete.
ii. There is no indication that benzovindiflupyr is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional uncertainty factors (UFs) to account for neurotoxicity.
iii. There is no evidence that benzovindiflupyr 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 benzovindiflupyr 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
benzovindiflupyr.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate food and water 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. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to benzovindiflupyr will occupy 43% of the aPAD for children 1-2 years
old, the
[[Page 29037]]
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
benzovindiflupyr from food and water will utilize 19% 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
benzovindiflupyr 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).
Benzovindiflupyr 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 benzovindiflupyr.
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 2100 for adults
and 510 for children. Because EPA's LOC for benzovindiflupyr is an 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).
An intermediate-term adverse effect was identified; however,
benzovindiflupyr is not registered for any use patterns that would
result in intermediate-term residential exposure. Intermediate-term
risk is assessed based on intermediate-term residential exposure plus
chronic dietary exposure. Because there is no intermediate-term
residential exposure and chronic dietary exposure has already been
assessed under the appropriately protective cPAD (which is at least as
protective as the POD used to assess intermediate-term risk), no
further assessment of intermediate-term risk is necessary, and EPA
relies on the chronic dietary risk assessment for evaluating
intermediate-term risk for benzovindiflupyr.
5. Aggregate cancer risk for U.S. population. Based on the
discussion in Unit III.A., EPA considers the chronic aggregate risk
assessment to be protective of any aggregate cancer risk. Based on the
results of the chronic risk assessment, which accounts for all chronic
toxicity, including carcinogenicity, EPA does not expect any cancer
risk to the U.S. population from aggregate exposure to
benzovindiflupyr.
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 benzovindiflupyr residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An adequate analytical method is available to enforce the proposed
tolerances for benzovindiflupyr in the specified grass commodities. A
Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) multi-
residue method (EN15662:2009) was developed for the determination of
residues of benzovindiflupyr via liquid chromatography-mass
spectrometry/mass spectrometry (LC-MS/MS)
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:
[email protected].
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 benzovindiflupyr.
C. Revisions to Petitioned-For Tolerances
The registrant petitioned for the use of benzovindiflupyr in or on
grasses grown for seed, forage at 0.15 parts per million (ppm), grasses
grown for seed, hay at 7 ppm and grasses grown for seed, straw at 6
ppm. The Agency has not established a crop group for ``grasses grown
for seed'' or otherwise defined what commodities are included in the
category of ``grasses grown for seed''. The closest group tolerance to
the commodity category requested is a crop group tolerance on grasses
(i.e., ``grass, forage, fodder and hay, group 17''), although this
group includes all grasses, whether grown for seed or not. Sufficient
representative commodity residue data were not submitted to support
establishing a crop group 17 tolerances; therefore, the Agency is
establishing tolerances for the individual grasses for which residue
data were submitted: Bluegrass, bromegrass, fescue, orchardgrass, and
ryegrass.
V. Conclusion
Therefore, tolerances are established for residues of
benzovindiflupyr, including its metabolites and degradates, in or on
bluegrass, forage at 0.15 ppm, bluegrass, hay at 7.0 ppm, bluegrass,
straw at 6.0 ppm, bromegrass, forage at 0.15 ppm, bromegrass, hay at
7.0 ppm, bromegrass, straw at 6.0 ppm, fescue, forage at 0.15 ppm,
fescue, hay at 7.0 ppm, fescue, straw at 6.0 ppm, orchardgrass, forage
at 0.15 ppm, orchardgrass, hay at 7.0 ppm, orchardgrass, straw at 6.0
ppm, and ryegrass, forage at 0.15 ppm, ryegrass, hay at 7.0 ppm, and
ryegrass, straw at 6.0 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); Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997); or Executive Order 13771,
entitled ``Reducing Regulations and Controlling Regulatory Costs'' (82
FR 9339, February 3, 2017). 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
[[Page 29038]]
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 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 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).
