Æ Also, changed the note to paragraph
(b): To replace ‘‘Material Safety Data
Sheets’’ with ‘‘Safety Data Sheets
(SDS);’’ and
• § 68.67 Process hazard analysis—
revised to require that the PHA must
now address the findings from all
incident investigations required under
§ 68.81, as well as any other potential
failure scenarios.
The only major rule provision that
would be affected by this rule (because
its March 14, 2018 compliance date is
before the delayed effective date of this
rule) is the emergency response
coordination provision, which has an
estimated annualized cost of $16 M.22 23
Therefore, based on the costs of the
provisions that would be affected by
this action, EPA has concluded that this
action is not a ‘‘major rule’’ as defined
by 5 U.S.C. 804(2).

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
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
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 spirotetramat
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with spirotetramat 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 target organs of toxicity following
subchronic and chronic oral exposures
to spirotetramat were different in rats
and dogs. The thyroid and thymus
glands were the target organs identified
in subchronic and chronic toxicity
studies in dogs while the testes were the
target organs identified in rats. The dog
was the most sensitive species, and in
both rats and dogs, males were more
sensitive than females. The thyroid
effects in the dog consisted of lower
circulating levels of thyroid hormones
(T3 and/or T4) along with a reduction
in follicle size, a possible indication of
reduced amount of colloid. In all dog
studies, thymus effects were observed
(reduced size, atrophy). In the one-year
study, this was described
microscopically as involution.
In rats, reported testicular effects
consisted of abnormal spermatozoa and
hypospermia in the epididymis,
decreased testicular weights, and
testicular degenerative vacuolation. An
investigative subchronic study where
rats were dosed with a primary enol
metabolite of spirotetramat reproduced
the same testicular effects as the parent
chemical, suggesting that this metabolite
is, at minimum, a primary contributor to
the observed male reproductive toxicity.
Consistent with this notion, orally
administered spirotetramat was
PO 00000
Frm 00041
Fmt 4700
Sfmt 4700
27145
demonstrated in rats to be extensively
metabolized, and males were noted to
achieve much higher systemic
exposures than their female
counterparts, which helps explain the
higher sensitivity of males. Other effects
reported in a rat chronic toxicity study
were associated with kidney effects
consisting of decreased organ weight
and tubular dilatation.
In one- and two-generation rat
reproductive toxicity studies, male
reproductive toxicity (abnormal sperm
cells and reproductive performance)
similar to that reported in subchronic
toxicity studies with adult rats was
reported in the first generation (F1)
males at relatively high dose levels. In
all cases, a well-defined no-observed
adverse-effect level (NOAEL) was
established.
There was evidence of increased
qualitative susceptibility in the rat
developmental study with reduced fetal
weight and increased incidences of
malformations and skeletal deviations
observed at the limit dose, while
maternal effects at this dose consisted of
only body-weight decrements. There
was no evidence of increased
quantitative or qualitative susceptibility
to offspring following pre- or post-natal
exposure to spirotetramat in the rabbit
developmental or two-generation
reproduction studies.
The only evidence of neurotoxicity in
the rat acute neurotoxicity study was
based on decreased motor and
locomotor activity, which occurred only
at relatively high dose levels. The rat
subchronic neurotoxicity (SCN) study
does not indicate a concern for
neurotoxicity, even at relatively high
dose levels. The results of an
immunotoxicity study in rats do not
indicate any functional deficits in
immune function.
There is no evidence of
carcinogenicity in chronic toxicity/
carcinogenicity studies performed in
rats and mice. Spirotetramat has been
classified as ‘‘not likely to be
carcinogenic to humans’’ based on lack
of evidence for carcinogenicity in rodent
studies. Spirotetramat was also negative
for mutagenicity and clastogenicity in in
vivo and in vitro assays.
Specific information on the studies
received and the nature of the adverse
effects caused by spirotetramat as well
as the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://

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-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides.
A summary of the toxicological
endpoints for spirotetramat used for
human risk assessment is discussed in

Departure/Levels of Concern of the final
rule published in the Federal Register
of Tuesday, October 25, 2016 (81 FR
73342) (FRL–89951–80).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to spirotetramat, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing spirotetramat tolerances in 40
CFR 180.641. EPA assessed dietary
exposures from spirotetramat 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 spirotetramat.
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
In estimating acute dietary exposure,
EPA used food consumption data from
the U.S. Department of Agriculture’s
(USDA’s) National Health and Nutrition
Examination Survey, What We Eat in
America (NHANES/WWEIA) from 2003
through 2008. As to residue levels in
food, EPA assumed tolerance-level
residues, 100 percent crop treated (PCT)
information for all commodities and
Dietary Exposure Evaluation Model
(DEEM) 7.81 default processing factors
where available.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA’s 2003–2008 NHANES/
WWEIA. As to residue levels in food,
EPA used 100 PCT, average field trial
residues for some commodities, and
tolerance-level residues for the
remaining commodities.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that spirotetramat 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.
The Agency did not use percent crop
treated estimates.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for spirotetramat in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
spirotetramat. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www2.epa.gov/
pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide.

Water (PRZM GW), the estimated
drinking water concentrations (EDWCs)
of spirotetramat and its metabolites and
degradates of concern for acute
exposures are estimated to be 395 parts
per billion (ppb) for surface water and
7.99 ppb for ground water.
Chronic exposures for non-cancer
assessments are estimated to be 395 ppb
for surface water and 5.36 ppb for
ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
both acute and chronic dietary risk
assessment, the water concentration
value of 395 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).
Spirotetramat is currently registered
for the following uses that could result
in residential exposures: Citrus trees
grown in residential areas and turf grass
including sod farm and golf course turf
only. There is the potential for postapplication dermal exposure from both
residential citrus tree and golf course
uses. The golf course use could result in
potential post-application dermal
exposure; however, there is no dermal
hazard and therefore, quantification of
dermal risk is not necessary. For the
residential citrus tree use, because the
product is sold in bulk packaging for
agricultural uses and the label requires
that handlers wear specific clothing
(e.g., long-sleeve shirt/long pants) and
the use of personal-protective
equipment (e.g., gloves), based on
current Agency policy, EPA has made
the assumption that this product is not
meant for homeowner use, and
therefore, there is no need to conduct a
quantitative residential handler
assessment.
Further information regarding EPA
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.’’

mstockstill on DSK30JT082PROD with RULES
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
spirotetramat and any other substances
and spirotetramat does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that spirotetramat has a
common mechanism of toxicity with
other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s Web site at: https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no evidence of quantitative
susceptibility of offspring following preor postnatal exposure to spirotetramat.
There is evidence of qualitative
susceptibility in the rat developmental
study, where developmental effects,
including reduced fetal weight and
increased incidences of malformations
and skeletal deviations, were observed
in the presence of body weight
decrements in maternal animals.
However, concern is low since effects
were only seen at the limit dose and
selected endpoints are protective of the
observed effects.
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
spirotetramat is complete.
ii. Although spirotetramat was shown
to elicit neurotoxic response in the
acute neurotoxicity study; however,
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
concern is low since the effects are wellcharacterized with clearly established
NOAEL/LOAEL values, the selected
endpoints are protective of the observed
neurotoxic effect, there are no
neurotoxic effects seen in the
subchronic neurotoxicity study, and the
existing toxicological database indicates
that spirotetramat is not a neurotoxic
chemical.
iii. There is no evidence of
quantitative susceptibility of offspring
following pre- or postnatal exposure.
There is evidence of qualitative
susceptibility in the rat developmental
study; however, there is no residual
uncertainty concerning these effects due
to the clear NOAEL/LOAELs in the
study for these effects. Moreover,
concern for these effects is low since
effects were only seen at the limit dose,
effects were seen in the presence of
maternal toxicity, and selected
endpoints are protective of the observed
effects.
iv. There are no residual uncertainties
identified in the exposure databases.
The acute dietary food and drinking
water exposure assessment utilizes
tolerance-level residues and 100 PCT
information for all commodities. The
chronic dietary food and drinking water
exposure assessment utilizes average
field trial residues for some
commodities, tolerance-level residues
for the remaining commodities, and 100
PCT. The chronic assessment is
somewhat refined; however, since it is
based on reliable data, it will not
underestimate exposure and risk. There
are no quantifiable potential exposure/
risks from residential citrus tree and golf
course uses. The drinking water
assessments provide conservative,
health-protective, high-end estimates of
water concentrations that will not likely
be exceeded. These assessments will not
underestimate the exposure and risks
posed by spirotetramat.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate exposure
estimates to the acute PAD (aPAD) and
chronic PAD (cPAD). For linear cancer
risks, EPA calculates the lifetime
probability of acquiring cancer given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the appropriate
PODs to ensure that an adequate MOE
exists.
1. Acute risk. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
27147
exposure from food and water to
spirotetramat will occupy 16% of the
aPAD for children 1–2 years old, the
population group receiving the greatest
exposure.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to spirotetramat
from food and water will utilize 77% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure.
3. Short- and Intermediate-term risks.
Short- and intermediate-term aggregate
exposures take into account short- and
intermediate-term residential exposures
plus chronic exposure to food and water
(considered to be a background
exposure level). A short- and
intermediate-term inhalation adverse
effect was identified; however,
spirotetramat is not registered for any
use patterns that would result in either
short- or intermediate-term inhalation
residential exposure. In a dermal
toxicity study, no evidence of dermal
hazard was found; therefore, dermal risk
was not included in the aggregate
assessment. Short- and intermediateterm aggregate risks are assessed based
on short- and intermediate-term
residential exposures plus chronic
dietary exposure. Because there is no
short- or intermediate-term residential
exposure and chronic dietary exposure
has already been assessed under the
appropriately protective cPAD (which is
at least as protective as the POD used to
assess short-term risk), no further
assessment of short- or intermediateterm risk is necessary, and EPA relies on
the chronic dietary risk assessment for
evaluating short- and intermediate-term
risks for spirotetramat.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
spirotetramat is not expected to pose a
cancer risk to humans.
5. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to spirotetramat
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(high-performance liquid
chromatography with tandem mass
spectrometry (HPLC–MS/MS)) is
available to enforce the tolerance
expression.

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 spirotetramat.
C. Response to Comments
One comment was received from an
anonymous source requesting that the
Agency deny IR–4’s petition for use of
spirotetramat on all food items claiming
it is a toxic chemical and its use would
result in harm to humans.
The Agency’s Response: The Agency
recognizes that some individuals believe
that certain pesticides are ‘‘toxic
chemicals’’ that should not be permitted
in our food; however, the commenter
provided no information demonstrating
toxicity of spirotetramat or that EPA
could use to evaluate the safety of the
pesticide. The existing legal framework
provided by section 408 of the Federal
Food, Drug and Cosmetic Act (FFDCA)
states that tolerances may be set when
persons seeking such tolerances or
exemptions have demonstrated that the
pesticide meets the safety standard
imposed by that statute. When new or
amended tolerances are requested for
residues of a pesticide in food or feed,
the Agency, as is required by Section
408 of the Federal Food, Drug and
Cosmetic Act (FFDCA), estimates the
risk of the potential exposure to these
residues. The Agency has concluded
after this risk assessment, which
includes the consideration of long-term
animal studies with spirotetramat, that
there is a reasonable certainty that no
VerDate Sep<11>2014
16:55 Jun 13, 2017
Jkt 241001
harm will result from aggregate human
exposure to spirotetramat and that,
accordingly, the use of spirotetramat on
petitioned-for food commodities is
‘‘safe.’’
D. Revisions to Petitioned-For
Tolerances
Based on available residue data, EPA
is establishing tolerance level on sugar
beet molasses at 0.30 ppm instead of
0.20 ppm, to cover anticipated residues.
In addition, EPA corrected the
commodity terminology for ‘‘sugar beet
root’’ and ‘‘sugar beet molasses’’ to
‘‘beet, sugar, roots’’ and ‘‘beet, sugar,
molasses,’’ respectively, in order to
conform to terms used in the Agency’s
Food and Feed Commodity Vocabulary.
V. Conclusion
Therefore, tolerances are established
for residues of spirotetramat, (cis-3-(2,5dimethylphenyl)-8-methoxy-2-oxo-1azaspiro[4.5]dec-3-en-4-yl-ethyl
carbonate) and its metabolites cis-3-(2,5dimethylphenyl)-4-hydroxy-8-methoxy1-azaspiro[4.5]dec-3-en-2-one, cis-3(2,5-dimethylphenyl)-3-hydroxy-8methoxy-1-azaspiro[4.5]decane-2,4dione, cis-3-(2,5-dimethylphenyl)-8methoxy-2-oxo-1-azaspiro[4.5]dec-3-en4-yl beta-D-glucopyranoside, and cis-3(2,5-dimethylphenyl)-4-hydroxy-8methoxy-1-azaspiro[4.5]decan-2-one,
calculated as the stoichiometric
equivalent of spirotetramat, in or on
beet, sugar, molasses at 0.30 ppm; beet,
sugar, roots at 0.15 ppm; carrot, roots at
0.15 ppm; fruit, stone, group 12–12 at
4.5 ppm; and nut, tree, group 14–12 at
0.25 ppm. In addition, EPA is revoking
the existing tolerances for fruit, stone,
group 12 and nut, tree, group 14 as they
are superseded by the new tolerances
for groups 12–12 and 14–12 established
under this final rule.
VI. Statutory and Executive Order
Reviews
This action establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the 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).

EPA issued documents pursuant to FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3),
[[Page 27145]]
announcing the filing of pesticide petitions (PPs) by IR-4 (PP 6E8467);
and Bayer CropScience (PP 6F8461). These petitions request that 40 CFR
180.641 be amended by establishing tolerances for residues of the
insecticide spirotetramat, (cis-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-
1-azaspiro[4.5]dec-3-en-4-yl-ethyl carbonate) and its metabolites cis-

(2,5-dimethylphenyl)-4-hydroxy-8-methoxy-1-azaspiro[4.5]decan-2-one,
calculated as the stoichiometric equivalent of spirotetramat, in or on
several commodities as follows:
Pesticide petition 6E8467 submitted by IR-4 Project Headquarters,
500 College Road East, Suite 201 W., Princeton, NJ 08540 requests
tolerances for carrot, roots at 0.15 parts per million (ppm); fruit,
stone, group 12-12 at 4.5 ppm; and nut, tree, group 14-12 at 0.25 ppm.
Pesticide petition 6F8461 submitted by Bayer CropScience, P.O. Box
12014, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709
requests tolerances on sugar beet, molasses at 0.20 ppm and sugar beet,
root at 0.15 ppm.
Summaries of the petitions prepared by the registrant, Bayer
CropScience, are available in the docket, https://www.regulations.gov
under document ID EPA-HQ-OPP-2016-0255. One comment was received in
response to the notices of filings. EPA's response to the comment is
discussed in Unit IV.C.
Based upon review of the data supporting the petitions, EPA has
revised the tolerance levels for several proposed commodities and
corrected several commodity listings. The reason for these changes are
explained in Unit IV.D.
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 spirotetramat including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with spirotetramat
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 target organs of toxicity following subchronic and chronic oral
exposures to spirotetramat were different in rats and dogs. The thyroid
and thymus glands were the target organs identified in subchronic and
chronic toxicity studies in dogs while the testes were the target
organs identified in rats. The dog was the most sensitive species, and
in both rats and dogs, males were more sensitive than females. The
thyroid effects in the dog consisted of lower circulating levels of
thyroid hormones (T3 and/or T4) along with a reduction in follicle
size, a possible indication of reduced amount of colloid. In all dog
studies, thymus effects were observed (reduced size, atrophy). In the
one-year study, this was described microscopically as involution.
In rats, reported testicular effects consisted of abnormal
spermatozoa and hypospermia in the epididymis, decreased testicular
weights, and testicular degenerative vacuolation. An investigative
subchronic study where rats were dosed with a primary enol metabolite
of spirotetramat reproduced the same testicular effects as the parent
chemical, suggesting that this metabolite is, at minimum, a primary
contributor to the observed male reproductive toxicity. Consistent with
this notion, orally administered spirotetramat was demonstrated in rats
to be extensively metabolized, and males were noted to achieve much
higher systemic exposures than their female counterparts, which helps
explain the higher sensitivity of males. Other effects reported in a
rat chronic toxicity study were associated with kidney effects
consisting of decreased organ weight and tubular dilatation.
In one- and two-generation rat reproductive toxicity studies, male
reproductive toxicity (abnormal sperm cells and reproductive
performance) similar to that reported in subchronic toxicity studies
with adult rats was reported in the first generation (F1)
males at relatively high dose levels. In all cases, a well-defined no-
observed adverse-effect level (NOAEL) was established.
There was evidence of increased qualitative susceptibility in the
rat developmental study with reduced fetal weight and increased
incidences of malformations and skeletal deviations observed at the
limit dose, while maternal effects at this dose consisted of only body-
weight decrements. There was no evidence of increased quantitative or
qualitative susceptibility to offspring following pre- or post-natal
exposure to spirotetramat in the rabbit developmental or two-generation
reproduction studies.
The only evidence of neurotoxicity in the rat acute neurotoxicity
study was based on decreased motor and locomotor activity, which
occurred only at relatively high dose levels. The rat subchronic
neurotoxicity (SCN) study does not indicate a concern for
neurotoxicity, even at relatively high dose levels. The results of an
immunotoxicity study in rats do not indicate any functional deficits in
immune function.
There is no evidence of carcinogenicity in chronic toxicity/
carcinogenicity studies performed in rats and mice. Spirotetramat has
been classified as ``not likely to be carcinogenic to humans'' based on
lack of evidence for carcinogenicity in rodent studies. Spirotetramat
was also negative for mutagenicity and clastogenicity in in vivo and in
vitro assays.
Specific information on the studies received and the nature of the
adverse effects caused by spirotetramat 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 document: ``Spirotetramat. Human Health Risk
Assessment for the Tolerance Petition for Residues in/on Sugar Beet and

docket ID number EPA-HQ-OPP-2016-0255.
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 spirotetramat used for
human risk assessment is discussed in Unit III. B. Toxicological Points
of Departure/Levels of Concern of the final rule published in the
Federal Register of Tuesday, October 25, 2016 (81 FR 73342) (FRL-89951-
80).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to spirotetramat, EPA considered exposure under the
petitioned-for tolerances as well as all existing spirotetramat
tolerances in 40 CFR 180.641. EPA assessed dietary exposures from
spirotetramat 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 spirotetramat.
In estimating acute dietary exposure, EPA used food consumption
data from the U.S. Department of Agriculture's (USDA's) National Health
and Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA)
from 2003 through 2008. As to residue levels in food, EPA assumed
tolerance-level residues, 100 percent crop treated (PCT) information
for all commodities and Dietary Exposure Evaluation Model (DEEM) 7.81
default processing factors where available.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA's 2003-2008
NHANES/WWEIA. As to residue levels in food, EPA used 100 PCT, average
field trial residues for some commodities, and tolerance-level residues
for the remaining commodities.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that spirotetramat 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.
The Agency did not use percent crop treated estimates.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for spirotetramat in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of spirotetramat. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Tier 1 Rice Model and Pesticide Root Zone Model Ground
Water (PRZM GW), the estimated drinking water concentrations (EDWCs) of
spirotetramat and its metabolites and degradates of concern for acute
exposures are estimated to be 395 parts per billion (ppb) for surface
water and 7.99 ppb for ground water.
Chronic exposures for non-cancer assessments are estimated to be
395 ppb for surface water and 5.36 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For both acute and chronic
dietary risk assessment, the water concentration value of 395 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).
Spirotetramat is currently registered for the following uses that
could result in residential exposures: Citrus trees grown in
residential areas and turf grass including sod farm and golf course
turf only. There is the potential for post-application dermal exposure
from both residential citrus tree and golf course uses. The golf course
use could result in potential post-application dermal exposure;
however, there is no dermal hazard and therefore, quantification of
dermal risk is not necessary. For the residential citrus tree use,
because the product is sold in bulk packaging for agricultural uses and
the label requires that handlers wear specific clothing (e.g., long-
sleeve shirt/long pants) and the use of personal-protective equipment
(e.g., gloves), based on current Agency policy, EPA has made the
assumption that this product is not meant for homeowner use, and
therefore, there is no need to conduct a quantitative residential
handler assessment.
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.''
[[Page 27147]]
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to spirotetramat and any
other substances and spirotetramat does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that spirotetramat has
a common mechanism of toxicity with other substances. For information
regarding EPA's efforts to determine which chemicals have a common
mechanism of toxicity and to evaluate the cumulative effects of such
chemicals, see EPA's Web site at: https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no evidence of
quantitative susceptibility of offspring following pre- or postnatal
exposure to spirotetramat. There is evidence of qualitative
susceptibility in the rat developmental study, where developmental
effects, including reduced fetal weight and increased incidences of
malformations and skeletal deviations, were observed in the presence of
body weight decrements in maternal animals. However, concern is low
since effects were only seen at the limit dose and selected endpoints
are protective of the observed effects.
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 spirotetramat is complete.
ii. Although spirotetramat was shown to elicit neurotoxic response
in the acute neurotoxicity study; however, concern is low since the
effects are well-characterized with clearly established NOAEL/LOAEL
values, the selected endpoints are protective of the observed
neurotoxic effect, there are no neurotoxic effects seen in the
subchronic neurotoxicity study, and the existing toxicological database
indicates that spirotetramat is not a neurotoxic chemical.
iii. There is no evidence of quantitative susceptibility of
offspring following pre- or postnatal exposure. There is evidence of
qualitative susceptibility in the rat developmental study; however,
there is no residual uncertainty concerning these effects due to the
clear NOAEL/LOAELs in the study for these effects. Moreover, concern
for these effects is low since effects were only seen at the limit
dose, effects were seen in the presence of maternal toxicity, and
selected endpoints are protective of the observed effects.
iv. There are no residual uncertainties identified in the exposure
databases. The acute dietary food and drinking water exposure
assessment utilizes tolerance-level residues and 100 PCT information
for all commodities. The chronic dietary food and drinking water
exposure assessment utilizes average field trial residues for some
commodities, tolerance-level residues for the remaining commodities,
and 100 PCT. The chronic assessment is somewhat refined; however, since
it is based on reliable data, it will not underestimate exposure and
risk. There are no quantifiable potential exposure/risks from
residential citrus tree and golf course uses. The drinking water
assessments provide conservative, health-protective, high-end estimates
of water concentrations that will not likely be exceeded. These
assessments will not underestimate the exposure and risks posed by
spirotetramat.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime probability of acquiring cancer given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the appropriate PODs to ensure that an
adequate MOE exists.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to spirotetramat will occupy 16% of the aPAD for children 1-2 years
old, the population group receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
spirotetramat from food and water will utilize 77% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure.
3. Short- and Intermediate-term risks. Short- and intermediate-term
aggregate exposures take into account short- and intermediate-term
residential exposures plus chronic exposure to food and water
(considered to be a background exposure level). A short- and
intermediate-term inhalation adverse effect was identified; however,
spirotetramat is not registered for any use patterns that would result
in either short- or intermediate-term inhalation residential exposure.
In a dermal toxicity study, no evidence of dermal hazard was found;
therefore, dermal risk was not included in the aggregate assessment.
Short- and intermediate-term aggregate risks are assessed based on
short- and intermediate-term residential exposures plus chronic dietary
exposure. Because there is no short- or intermediate-term residential
exposure and chronic dietary exposure has already been assessed under
the appropriately protective cPAD (which is at least as protective as
the POD used to assess short-term risk), no further assessment of
short- or intermediate-term risk is necessary, and EPA relies on the
chronic dietary risk assessment for evaluating short- and intermediate-
term risks for spirotetramat.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, spirotetramat is not expected to pose a cancer risk to humans.
5. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to spirotetramat residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (high-performance liquid
chromatography with tandem mass spectrometry (HPLC-MS/MS)) is available
to enforce the tolerance expression.
[[Page 27148]]
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 spirotetramat.
C. Response to Comments
One comment was received from an anonymous source requesting that
the Agency deny IR-4's petition for use of spirotetramat on all food
items claiming it is a toxic chemical and its use would result in harm
to humans.
The Agency's Response: The Agency recognizes that some individuals
believe that certain pesticides are ``toxic chemicals'' that should not
be permitted in our food; however, the commenter provided no
information demonstrating toxicity of spirotetramat or that EPA could
use to evaluate the safety of the pesticide. The existing legal
framework provided by section 408 of the Federal Food, Drug and
Cosmetic Act (FFDCA) states that tolerances may be set when persons
seeking such tolerances or exemptions have demonstrated that the
pesticide meets the safety standard imposed by that statute. When new
or amended tolerances are requested for residues of a pesticide in food
or feed, the Agency, as is required by Section 408 of the Federal Food,
Drug and Cosmetic Act (FFDCA), estimates the risk of the potential
exposure to these residues. The Agency has concluded after this risk
assessment, which includes the consideration of long-term animal
studies with spirotetramat, that there is a reasonable certainty that
no harm will result from aggregate human exposure to spirotetramat and
that, accordingly, the use of spirotetramat on petitioned-for food
commodities is ``safe.''
D. Revisions to Petitioned-For Tolerances
Based on available residue data, EPA is establishing tolerance
level on sugar beet molasses at 0.30 ppm instead of 0.20 ppm, to cover
anticipated residues. In addition, EPA corrected the commodity
terminology for ``sugar beet root'' and ``sugar beet molasses'' to
``beet, sugar, roots'' and ``beet, sugar, molasses,'' respectively, in
order to conform to terms used in the Agency's Food and Feed Commodity
Vocabulary.
V. Conclusion
Therefore, tolerances are established for residues of
spirotetramat, (cis-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-1-
azaspiro[4.5]dec-3-en-4-yl-ethyl carbonate) and its metabolites cis-3-
(2,5-dimethylphenyl)-4-hydroxy-8-methoxy-1-azaspiro[4.5]dec-3-en-2-one,
cis-3-(2,5-dimethylphenyl)-3-hydroxy-8-methoxy-1-azaspiro[4.5]decane-
2,4-dione, cis-3-(2,5-dimethylphenyl)-8-methoxy-2-oxo-1-
azaspiro[4.5]dec-3-en-4-yl beta-D-glucopyranoside, and cis-3-(2,5-
dimethylphenyl)-4-hydroxy-8-methoxy-1-azaspiro[4.5]decan-2-one,
calculated as the stoichiometric equivalent of spirotetramat, in or on
beet, sugar, molasses at 0.30 ppm; beet, sugar, roots at 0.15 ppm;
carrot, roots at 0.15 ppm; fruit, stone, group 12-12 at 4.5 ppm; and
nut, tree, group 14-12 at 0.25 ppm. In addition, EPA is revoking the
existing tolerances for fruit, stone, group 12 and nut, tree, group 14
as they are superseded by the new tolerances for groups 12-12 and 14-12
established under this final rule.
VI. Statutory and Executive Order Reviews
This action establishes tolerances under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the 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).
