Benzyl acetate; Exemption From the
Requirement of a Tolerance
Environmental Protection
Agency (EPA).
ACTION: Final rule.
AGENCY:
This regulation establishes an
exemption from the requirement of a
tolerance for residues of benzyl acetate
(CAS Reg. No. 140–11–4), when used as
an inert ingredient (solvent) in pesticide
formulations applied to growing crops
only under 40 CFR 180.920. Technology
Sciences Group, on behalf of the
Huntsman Corporation, submitted a
petition to EPA under the Federal Food,
Drug, and Cosmetic Act (FFDCA),
requesting establishment of an
exemption from the requirement of a
tolerance. This regulation eliminates the
need to establish a maximum
permissible level for residues of benzyl
acetate.
DATES: This regulation is effective
February 12, 2016. Objections and
requests for hearings must be received
on or before April 12, 2016, and must

II. Petition for Exemption
In the Federal Register of Wednesday,
March 4, 2015 (80 FR 11611) (FRL–
9922–68), EPA issued a document
pursuant to FFDCA section 408, 21
U.S.C. 346a, announcing the filing of a
pesticide petition ((PP) IN–10748) by
Technology Sciences Group (TSG) 1150
18th Street NW., Suite 1000,
Washington, DC 20036, on behalf of the
Huntsman Corporation, 8600 Gosling
Road, The Woodlands, TX 77381. The
petition requested that 40 CFR 180.920
be amended by establishing an
exemption from the requirement of a
tolerance for residues of benzyl acetate
(CAS Reg. No. 140–11–4) when used as
an inert ingredient (solvent) in pesticide
formulations applied to growing crops
only. That document referenced a
summary of the petition prepared by the
Huntsman Corporation, the petitioner,
which is available in the docket,
https://www.regulations.gov. There were
no comments received in response to
the notice of filing.
III. Inert Ingredient Definition
Inert ingredients are all ingredients
that are not active ingredients as defined
in 40 CFR 153.125 and include, but are
not limited to, the following types of
ingredients (except when they have a
pesticidal efficacy of their own):
Solvents such as alcohols and
hydrocarbons; surfactants such as
polyoxyethylene polymers and fatty
acids; carriers such as clay and
diatomaceous earth; thickeners such as
carrageenan and modified cellulose;
wetting, spreading, and dispersing
agents; propellants in aerosol
dispensers; microencapsulating agents;
and emulsifiers. The term ‘‘inert’’ is not
intended to imply nontoxicity; the
ingredient may or may not be
chemically active. Generally, EPA has
exempted inert ingredients from the
requirement of a tolerance based on the

IV. Aggregate Risk Assessment and
Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for 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. . . .’’
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be clearly
demonstrated that the risks from
aggregate exposure to pesticide
chemical residues under reasonably
foreseeable circumstances will pose no
appreciable risks to human health. In
order to determine the risks from
aggregate exposure to pesticide inert
ingredients, the Agency considers the
toxicity of the inert in conjunction with
possible exposure to residues of the
inert ingredient through food, drinking
water, and through other exposures that
occur as a result of pesticide use in
residential settings. If EPA is able to
determine that a finite tolerance is not
necessary to ensure that there is a
reasonable certainty that no harm will
result from aggregate exposure to the
inert ingredient, an exemption from the
requirement of a tolerance may be
established.
Consistent with FFDCA section
408(c)(2)(A), and the factors specified in
FFDCA section 408(c)(2)(B), 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 benzyl acetate
including exposure resulting from the
exemption established by this action.
EPA’s assessment of exposures and risks
associated with benzyl acetate follows.
VerDate Sep<11>2014
16:06 Feb 11, 2016
Jkt 238001
EPA has evaluated the available
toxicity data and considered their
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. Specific
information on the studies received and
the nature of the adverse effects caused
by benzyl acetate as well as the noobserved-adverse-effect-level (NOAEL)
and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies
are discussed in this unit.
Benzyl acetate exhibits low levels of
toxicity via the dermal route of exposure
in rabbits and inhalation and oral routes
of exposure in rats. It is mildly irritating
to the skin and minimally irritating to
the eyes in rabbits. It is not a skin
sensitizer in guinea pigs.
In a 13-week feeding study in the rat,
atrophic seminiferous tubules were
observed in male rats at dose levels of
12,500 parts per millions (ppm)
(equivalent to 900 milligrams/kilogram/
day (mg/kg/day)). The NOAEL was
identified as 6,250 ppm (460 mg/kg/
day). In mice, following 13 weeks of
exposure via the diet, decreased body
weight and food consumption were
observed at all doses. The LOAEL was
3,130 ppm (425 mg/kg/day). A NOAEL
was not established.
In a developmental toxicity study in
the rat, maternal and fetal toxicity were
observed at 1,000 mg/kg/day. Maternal
toxicity was manifested as decreased
body weight and fetal toxicity was
manifested as reduced body weights,
increased incidence of dilation of the
renal pelvis and skeletal variations.
Although qualitative fetal susceptibility
is observed, fetal effects occur in the
presence of maternal toxicity and a clear
NOAEL of 500 mg/kg/day was
established for maternal and
developmental toxicity.
The potential for benzyl acetate to be
genotoxic was evaluated in a battery of
in vivo mammalian genotoxicity studies.
It was negative in the Ames assay (with
and without metabolic activation), sister
chromatid exchange assay, Chinese
hamster ovary cell assay, mouse
micronucleus assay and in the dominant
lethal assay in Drosophila. However, it
gave a positive response in the mouse
lymphoma assay. Since other
chromosomal aberrations assays as well
as gene mutation assays and a dominant
lethal assay gave a negative response, it
is concluded that benzyl acetate is
unlikely to be mutagenic.

Evidence of neurotoxicity and
neuronal degeneration was identified in
the 13-week studies in rats and mice.
Signs of neurotoxicity included tremors
and ataxia that were associated with the
degeneration of the glial cells in the
cerebellum and hippocampus at the
doses ≥12,500 ppm (≥2,000 mg/kg/day).
Since these effects were induced at
doses above the limit dose (1,000 mg/
kg/day) and the established cRfD of 1.10
mg/kg/day, will be protective of these
effects, the concern is low for these
effects.
There is evidence that benzyl acetate
suppresses immune function in
mammalian systems in the rat however
this effect occurs only at a dose that is
lethal and well above the limit dose. In
the 13-week feeding study in the rat, a
decrease in the cellular components of
the bone marrow, thymus and lymphoid
follicles was observed at 50,000 ppm
(3,900 mg/kg/day for males and 4,500
mg/kg/day for females), the highest dose
tested and well above the limit dose.
The NOAEL for this study was 12,500
ppm (900 mg/kg/day). The potential for
immunotoxicity is not of concern
because the effects occur well above the
limit dose and the exposure to benzyl
acetate through the proposed use is
unlikely to occur at such a high dose.
The carcinogenicity of benzyl acetate
in F344/N rats, and B6C3F1 mice using
was evaluated using the gavage method
of administration and corn oil as a
vehicle. There were indications that
benzyl acetate increased the incidences
of pancreatic acinar cell adenomas in
male rats and the incidences of
hepatocellular adenomas and
forestomach neoplasms in male and
female mice. Because of the
confounding effects of corn oil on the
incidences of pancreatic neoplasm and
because of the controversy over the use
of the gavage route of administration,
the National Toxicology Program (NTP)
decided to re-study benzyl acetate using
the dosed feed route of administration.
In 1993, the NTP conducted a second
set of carcinogenicity studies in rats and
mice using the dose feed route of
administration. Benzyl acetate was
administered via the diet to rats and
mice at doses up to 12,000 ppm (510/
575 mg/kg/day, male/female). Toxicity
was not observed in rats at any dose. In
mice, males and females exhibited
reduced body weight throughout the
entire study at 345/375 mg/kg/day.
There was no evidence of
carcinogenicity in mice and rats. Since
the exposure to benzyl acetate is likely
to occur via the dietary route in humans
and there is some uncertainty about the
use of corn oil in the gavage study, it is
concluded that benzyl acetate is

unlikely to be carcinogenic to humans
via the dietary route of exposure.
In metabolism studies approximately
90% of benzyl acetate is excreted as
metabolites primarily in the urine after
oral or percutaneous administration.
None was detected in the adipose tissue,
blood, kidney, liver, lung, muscle, skin
or stomach. The major metabolite in the
urine was hippuric acid and 95 to 99%
of the excreted dose was in this form.
Less than 4% remained in the carcass.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
The point of departure for benzyl
acetate is 110 mg/kg/day from the NTP
2-year carcinogenicity study in mice
(dietary study) based on decreased in
body weights in both sexes at the
LOAEL of 345/375 mg/kg/day. There
was no NOAEL observed in a 90-day
toxicity study in mice based on the
effects on body weights seen at all doses
(lowest dose tested was 3,130 ppm;
equal to 425 mg/kg/day); however, in a
carcinogenicity study in mice no effects
on body weight were seen at 110 mg/kg/
day, therefore, the NOAEL for the
carcinogenicity study would be
protective of decreased body weights
seen in a 90-day study in mice.
Therefore, 90-day toxicity study in mice
was not selected. This endpoint was
VerDate Sep<11>2014
16:06 Feb 11, 2016
Jkt 238001
used for all exposure scenarios. The
dermal absorption and inhalation
factors were 100%. The Agency applied
an interspecies uncertainty factor (10X)
and an intraspecies uncertainty factor
(10X); the FQPA safety factor was
reduced to 1X.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to benzyl acetate, EPA
considered exposure under the
proposed exemption from the
requirement of a tolerance. EPA
assessed dietary exposures from benzyl
acetate in food as follows:
An acute dietary risk assessment was
not conducted because no endpoint of
concern following a single exposure was
identified in the available studies. A
chronic dietary exposure assessment
was completed and performed using the
Dietary Exposure Evaluation Model
DEEM–FCIDTM, Version 3.16, which
includes food consumption information
from the U.S. Department of
Agriculture’s National Health and
Nutrition Examination Survey, ‘‘What
We Eat In America’’, (NHANES/
WWEIA). This dietary survey was
conducted from 2003 to 2008. In the
absence of actual residue data, the inert
ingredient evaluation is based on a
highly conservative model that assumes
that the residue level of the inert
ingredient would be no higher than the
highest established tolerance for an
active ingredient on a given commodity.
Implicit in this assumption is that there
would be similar rates of degradation
between the active and inert ingredient
(if any) and that the concentration of
inert ingredient in the scenarios leading
to these highest of tolerances would be
no higher than the concentration of the
active ingredient. The model assumes
100 percent crop treated (PCT) for all
crops and that every food eaten by a
person each day has tolerance-level
residues. A complete description of the
general approach taken to assess inert
ingredient risks in the absence of
residue data is contained in the
memorandum entitled ‘‘Alkyl Amines
Polyalkoxylates (Cluster 4): Acute and
Chronic Aggregate (Food and Drinking
Water) Dietary Exposure and Risk
Assessments for the Inerts’’ (D361707, S.
Piper, 2/25/09) and can be found at
https://www.regulations.gov in docket ID
number EPA–HQ–OPP–2008–0738.
Nonpesticidal dietary exposure to
benzyl acetate (e.g., use as a food
additive (flavoring agent) were also
considered as part of aggregate chronic
dietary risk assessment.
2. Dietary exposure from drinking
water. For the purpose of the screening-
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
7475
level dietary risk assessment to support
this request for an exemption from the
requirement of a tolerance for benzyl
acetate, a conservative drinking water
concentration value of 100 ppb based on
screening level modeling was used to
assess the contribution to drinking
water for the chronic dietary risk
assessments for parent compound.
These values were directly entered into
the dietary exposure model.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., textiles (clothing and diapers),
carpets, swimming pools, and hard
surface disinfection on walls, floors,
tables).
Based upon the requested use of
benzyl acetate, the Agency does not
expect non-occupational, non-dietary
exposures. However, there is a potential
for residential exposure via nonpesticidal uses such as use in cosmetics
and other, pesticide uses, once it is
approved. The residential exposure
could occur via ingestion products
containing benzyl acetate, and via
dermal and inhalation routes of
exposure through use of products
containing benzyl acetate in residential
settings. These residential pesticide
exposures are considered short-term and
intermediate-term in nature. Residential
exposures to benzyl acetate as the result
of its use as a cosmetic ingredient may
be short-, intermediate- or long-term in
nature. The aggregate-short term
exposure assessment for benzyl acetate
considers exposures from the pesticidal
and nonpesticidal uses (i.e., flavoring
agent and cosmetic ingredient) and
would be protective of any potential
long-term exposure to benzyl acetate
resulting from its use in cosmetics as the
same toxicological point of departure is
used for all exposure durations and the
average daily exposure estimates for
cosmetic use is conservatively applied
to all exposure durations.
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 benzyl acetate to share a common
mechanism of toxicity with any other
substances, and benzyl acetate does not
appear to produce a toxic metabolite
produced by other substances. For the
purposes of this tolerance action,
therefore, EPA has assumed that benzyl
E:\FR\FM\12FER1.SGM
12FER1
7476
Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations
srobinson on DSK5SPTVN1PROD with RULES
acetate does not have a common
mechanism of toxicity with other
substances. For information regarding
EPA’s efforts to determine which
chemicals have a common mechanism
of toxicity and to evaluate the
cumulative effects of such chemicals,
see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity
Qualitative fetal susceptibility was
observed in the developmental study in
rats. Maternal (decrease in body weight)
and fetal (reduced body weights,
increased incidence of dilation of the
renal pelvis and skeletal variations)
toxicity were observed at 1,000 mg/kg/
day, the limit dose. Since fetal toxicity
occurs in the presence of maternal
toxicity and a clear NOAEL of 500 mg/
kg/day was established, the established
cRfD (1.10 mg/kg/day) will be protective
of these effects. The potential for
reproduction toxicity was observed in
the 13-week dietary study in rats.
Atrophy of seminiferous tubules was
observed in males at 12,500 ppm (900
mg/kg/day). However, the concern for
reproduction toxicity is low since
effects occurred at a high dose and a
clear NOAEL of 6,250 ppm (460 mg/kg/
day) was established. Therefore, the
established cRfD will be protective of
this effect. In addition, no female
reproductive parameters were affected
in the developmental toxicity study in
rats.
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 benzyl
acetate contains the following studies
that are adequate to evaluate the
potential toxicity of benzyl acetate for
infants and children: A thirteen week
VerDate Sep<11>2014
16:06 Feb 11, 2016
Jkt 238001
feeding study in the rat, a 13-week
feeding study in the mouse, a
developmental toxicity study in the rat,
several in vivo and in vitro mutagenicity
studies, and carcinogenicity studies in
mice and rats via gavage and dietary
studies.
ii. Evidence of neurotoxicity and
neuronal degeneration seen in a
thirteen-week study was determined not
to exceed levels of concern since the
effects occurred at doses that were well
above the limit dose (1,000 mg/kg/day).
The established cRfD is 1.10 mg/kg/day
therefore is protective of these effects.
iii. Qualitative fetal susceptibility was
observed in the developmental study in
rats. Maternal (decrease in body weight)
and fetal (reduced body weights,
increased incidence of dilation of the
renal pelvis and skeletal variations)
toxicity were observed at 1,000 mg/kg/
day, the limit dose. Since fetal toxicity
occurs in the presence of maternal
toxicity and a clear NOAEL of 500 mg/
kg/day was established, the established
cRfD (1.10 mg/kg/day) will be protective
of these effects. The potential for
reproduction toxicity was observed in
the 13-week dietary study in rats.
Atrophy of seminiferous tubules was
observed in males at 12,500 ppm (900
mg/kg/day). However, the concern for
reproductive toxicity is low since effects
occurred at a high dose and a clear
NOAEL of 6,250 ppm (460 mg/kg/day)
was established.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100% CT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to benzyl
acetate 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 benzyl acetate.
E. Aggregate Risks and Determination of
Safety Section
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.
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, benzyl acetate is not
expected to pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to benzyl acetate
from food and water will utilize 62.9%
of the cPAD for children ages 1 to 2, the
population group receiving the greatest
exposure.
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).
Benzyl acetate is likely to be used as
an inert ingredient in pesticide products
that are 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 benzyl acetate. Using the
exposure assumptions described in this
unit for screening-level short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 150 for children ages 1 to 2 and
260 for adults. Because EPA’s level of
concern for benzyl acetate is a MOE of
100 or below, these MOEs are not of
concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Because no intermediate-term adverse
effect was identified, benzyl acetate is
not expected to pose an intermediateterm risk.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in the
dietary carcinogenicity studies in mice
and rats, benzyl acetate is not expected
to pose a cancer risk to humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to benzyl
acetate residues.
V. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the

Federal Register / Vol. 81, No. 29 / Friday, February 12, 2016 / Rules and Regulations
Agency is establishing an exemption

VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.920 for benzyl
aceetate (CAS Reg. No. 140–11–4) when
used as an inert ingredient (solvent) in
pesticide formulations applied to
growing crops only.

VII. Statutory and Executive Order
Reviews
This action establishes an exemption
from the requirement of a tolerance
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 exemption 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
VerDate Sep<11>2014

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).
VIII. 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. Petition for Exemption
In the Federal Register of Wednesday, March 4, 2015 (80 FR 11611)
(FRL-9922-68), EPA issued a document pursuant to FFDCA section 408, 21
U.S.C. 346a, announcing the filing of a pesticide petition ((PP) IN-
10748) by Technology Sciences Group (TSG) 1150 18th Street NW., Suite
1000, Washington, DC 20036, on behalf of the Huntsman Corporation, 8600
Gosling Road, The Woodlands, TX 77381. The petition requested that 40
CFR 180.920 be amended by establishing an exemption from the
requirement of a tolerance for residues of benzyl acetate (CAS Reg. No.
140-11-4) when used as an inert ingredient (solvent) in pesticide
formulations applied to growing crops only. That document referenced a
summary of the petition prepared by the Huntsman Corporation, the
petitioner, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the
notice of filing.
III. Inert Ingredient Definition
Inert ingredients are all ingredients that are not active
ingredients as defined in 40 CFR 153.125 and include, but are not
limited to, the following types of ingredients (except when they have a
pesticidal efficacy of their own): Solvents such as alcohols and
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty
acids; carriers such as clay and diatomaceous earth; thickeners such as
carrageenan and modified cellulose; wetting, spreading, and dispersing
agents; propellants in aerosol dispensers; microencapsulating agents;
and emulsifiers. The term ``inert'' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active.
Generally, EPA has exempted inert ingredients from the requirement of a
tolerance based on the
[[Page 7474]]
low toxicity of the individual inert ingredients.
IV. Aggregate Risk Assessment and Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for 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. . . .''
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be clearly demonstrated that the risks from
aggregate exposure to pesticide chemical residues under reasonably
foreseeable circumstances will pose no appreciable risks to human
health. In order to determine the risks from aggregate exposure to
pesticide inert ingredients, the Agency considers the toxicity of the
inert in conjunction with possible exposure to residues of the inert
ingredient through food, drinking water, and through other exposures
that occur as a result of pesticide use in residential settings. If EPA
is able to determine that a finite tolerance is not necessary to ensure
that there is a reasonable certainty that no harm will result from
aggregate exposure to the inert ingredient, an exemption from the
requirement of a tolerance may be established.
Consistent with FFDCA section 408(c)(2)(A), and the factors
specified in FFDCA section 408(c)(2)(B), 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 benzyl acetate including
exposure resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with benzyl acetate
follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
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. Specific information on the studies received and the nature
of the adverse effects caused by benzyl acetate as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies are discussed in this
unit.
Benzyl acetate exhibits low levels of toxicity via the dermal route
of exposure in rabbits and inhalation and oral routes of exposure in
rats. It is mildly irritating to the skin and minimally irritating to
the eyes in rabbits. It is not a skin sensitizer in guinea pigs.
In a 13-week feeding study in the rat, atrophic seminiferous
tubules were observed in male rats at dose levels of 12,500 parts per
millions (ppm) (equivalent to 900 milligrams/kilogram/day (mg/kg/day)).
The NOAEL was identified as 6,250 ppm (460 mg/kg/day). In mice,
following 13 weeks of exposure via the diet, decreased body weight and
food consumption were observed at all doses. The LOAEL was 3,130 ppm
(425 mg/kg/day). A NOAEL was not established.
In a developmental toxicity study in the rat, maternal and fetal
toxicity were observed at 1,000 mg/kg/day. Maternal toxicity was
manifested as decreased body weight and fetal toxicity was manifested
as reduced body weights, increased incidence of dilation of the renal
pelvis and skeletal variations. Although qualitative fetal
susceptibility is observed, fetal effects occur in the presence of
maternal toxicity and a clear NOAEL of 500 mg/kg/day was established
for maternal and developmental toxicity.
The potential for benzyl acetate to be genotoxic was evaluated in a
battery of in vivo mammalian genotoxicity studies. It was negative in
the Ames assay (with and without metabolic activation), sister
chromatid exchange assay, Chinese hamster ovary cell assay, mouse
micronucleus assay and in the dominant lethal assay in Drosophila.
However, it gave a positive response in the mouse lymphoma assay. Since
other chromosomal aberrations assays as well as gene mutation assays
and a dominant lethal assay gave a negative response, it is concluded
that benzyl acetate is unlikely to be mutagenic.
Evidence of neurotoxicity and neuronal degeneration was identified
in the 13-week studies in rats and mice. Signs of neurotoxicity
included tremors and ataxia that were associated with the degeneration
of the glial cells in the cerebellum and hippocampus at the doses
>=12,500 ppm (>=2,000 mg/kg/day). Since these effects were induced at
doses above the limit dose (1,000 mg/kg/day) and the established cRfD
of 1.10 mg/kg/day, will be protective of these effects, the concern is
low for these effects.
There is evidence that benzyl acetate suppresses immune function in
mammalian systems in the rat however this effect occurs only at a dose
that is lethal and well above the limit dose. In the 13-week feeding
study in the rat, a decrease in the cellular components of the bone
marrow, thymus and lymphoid follicles was observed at 50,000 ppm (3,900
mg/kg/day for males and 4,500 mg/kg/day for females), the highest dose
tested and well above the limit dose. The NOAEL for this study was
12,500 ppm (900 mg/kg/day). The potential for immunotoxicity is not of
concern because the effects occur well above the limit dose and the
exposure to benzyl acetate through the proposed use is unlikely to
occur at such a high dose.
The carcinogenicity of benzyl acetate in F344/N rats,
and B6C3F1 mice using was evaluated using the gavage method
of administration and corn oil as a vehicle. There were indications
that benzyl acetate increased the incidences of pancreatic acinar cell
adenomas in male rats and the incidences of hepatocellular adenomas and
forestomach neoplasms in male and female mice. Because of the
confounding effects of corn oil on the incidences of pancreatic
neoplasm and because of the controversy over the use of the gavage
route of administration, the National Toxicology Program (NTP) decided
to re-study benzyl acetate using the dosed feed route of
administration. In 1993, the NTP conducted a second set of
carcinogenicity studies in rats and mice using the dose feed route of
administration. Benzyl acetate was administered via the diet to rats
and mice at doses up to 12,000 ppm (510/575 mg/kg/day, male/female).
Toxicity was not observed in rats at any dose. In mice, males and
females exhibited reduced body weight throughout the entire study at
345/375 mg/kg/day. There was no evidence of carcinogenicity in mice and
rats. Since the exposure to benzyl acetate is likely to occur via the
dietary route in humans and there is some uncertainty about the use of
corn oil in the gavage study, it is concluded that benzyl acetate is
[[Page 7475]]
unlikely to be carcinogenic to humans via the dietary route of
exposure.
In metabolism studies approximately 90% of benzyl acetate is
excreted as metabolites primarily in the urine after oral or
percutaneous administration. None was detected in the adipose tissue,
blood, kidney, liver, lung, muscle, skin or stomach. The major
metabolite in the urine was hippuric acid and 95 to 99% of the excreted
dose was in this form. Less than 4% remained in the carcass.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
The point of departure for benzyl acetate is 110 mg/kg/day from the
NTP 2-year carcinogenicity study in mice (dietary study) based on
decreased in body weights in both sexes at the LOAEL of 345/375 mg/kg/
day. There was no NOAEL observed in a 90-day toxicity study in mice
based on the effects on body weights seen at all doses (lowest dose
tested was 3,130 ppm; equal to 425 mg/kg/day); however, in a
carcinogenicity study in mice no effects on body weight were seen at
110 mg/kg/day, therefore, the NOAEL for the carcinogenicity study would
be protective of decreased body weights seen in a 90-day study in mice.
Therefore, 90-day toxicity study in mice was not selected. This
endpoint was used for all exposure scenarios. The dermal absorption and
inhalation factors were 100%. The Agency applied an interspecies
uncertainty factor (10X) and an intraspecies uncertainty factor (10X);
the FQPA safety factor was reduced to 1X.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to benzyl acetate, EPA considered exposure under the proposed
exemption from the requirement of a tolerance. EPA assessed dietary
exposures from benzyl acetate in food as follows:
An acute dietary risk assessment was not conducted because no
endpoint of concern following a single exposure was identified in the
available studies. A chronic dietary exposure assessment was completed
and performed using the Dietary Exposure Evaluation Model DEEM-
FCID\TM\, Version 3.16, which includes food consumption information
from the U.S. Department of Agriculture's National Health and Nutrition
Examination Survey, ``What We Eat In America'', (NHANES/WWEIA). This
dietary survey was conducted from 2003 to 2008. In the absence of
actual residue data, the inert ingredient evaluation is based on a
highly conservative model that assumes that the residue level of the
inert ingredient would be no higher than the highest established
tolerance for an active ingredient on a given commodity. Implicit in
this assumption is that there would be similar rates of degradation
between the active and inert ingredient (if any) and that the
concentration of inert ingredient in the scenarios leading to these
highest of tolerances would be no higher than the concentration of the
active ingredient. The model assumes 100 percent crop treated (PCT) for
all crops and that every food eaten by a person each day has tolerance-
level residues. A complete description of the general approach taken to
assess inert ingredient risks in the absence of residue data is
contained in the memorandum entitled ``Alkyl Amines Polyalkoxylates
(Cluster 4): Acute and Chronic Aggregate (Food and Drinking Water)
Dietary Exposure and Risk Assessments for the Inerts'' (D361707, S.
Piper, 2/25/09) and can be found at https://www.regulations.gov in
docket ID number EPA-HQ-OPP-2008-0738. Nonpesticidal dietary exposure
to benzyl acetate (e.g., use as a food additive (flavoring agent) were
also considered as part of aggregate chronic dietary risk assessment.
2. Dietary exposure from drinking water. For the purpose of the
screening-level dietary risk assessment to support this request for an
exemption from the requirement of a tolerance for benzyl acetate, a
conservative drinking water concentration value of 100 ppb based on
screening level modeling was used to assess the contribution to
drinking water for the chronic dietary risk assessments for parent
compound. These values were directly entered into the dietary exposure
model.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., textiles (clothing and diapers), carpets, swimming
pools, and hard surface disinfection on walls, floors, tables).
Based upon the requested use of benzyl acetate, the Agency does not
expect non-occupational, non-dietary exposures. However, there is a
potential for residential exposure via non-pesticidal uses such as use
in cosmetics and other, pesticide uses, once it is approved. The
residential exposure could occur via ingestion products containing
benzyl acetate, and via dermal and inhalation routes of exposure
through use of products containing benzyl acetate in residential
settings. These residential pesticide exposures are considered short-
term and intermediate-term in nature. Residential exposures to benzyl
acetate as the result of its use as a cosmetic ingredient may be short-
, intermediate- or long-term in nature. The aggregate-short term
exposure assessment for benzyl acetate considers exposures from the
pesticidal and nonpesticidal uses (i.e., flavoring agent and cosmetic
ingredient) and would be protective of any potential long-term exposure
to benzyl acetate resulting from its use in cosmetics as the same
toxicological point of departure is used for all exposure durations and
the average daily exposure estimates for cosmetic use is conservatively
applied to all exposure durations.
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 benzyl
acetate to share a common mechanism of toxicity with any other
substances, and benzyl acetate does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that benzyl
[[Page 7476]]
acetate does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity Qualitative fetal
susceptibility was observed in the developmental study in rats.
Maternal (decrease in body weight) and fetal (reduced body weights,
increased incidence of dilation of the renal pelvis and skeletal
variations) toxicity were observed at 1,000 mg/kg/day, the limit dose.
Since fetal toxicity occurs in the presence of maternal toxicity and a
clear NOAEL of 500 mg/kg/day was established, the established cRfD
(1.10 mg/kg/day) will be protective of these effects. The potential for
reproduction toxicity was observed in the 13-week dietary study in
rats. Atrophy of seminiferous tubules was observed in males at 12,500
ppm (900 mg/kg/day). However, the concern for reproduction toxicity is
low since effects occurred at a high dose and a clear NOAEL of 6,250
ppm (460 mg/kg/day) was established. Therefore, the established cRfD
will be protective of this effect. In addition, no female reproductive
parameters were affected in the developmental toxicity study in rats.
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 benzyl acetate contains the following
studies that are adequate to evaluate the potential toxicity of benzyl
acetate for infants and children: A thirteen week feeding study in the
rat, a 13-week feeding study in the mouse, a developmental toxicity
study in the rat, several in vivo and in vitro mutagenicity studies,
and carcinogenicity studies in mice and rats via gavage and dietary
studies.
ii. Evidence of neurotoxicity and neuronal degeneration seen in a
thirteen-week study was determined not to exceed levels of concern
since the effects occurred at doses that were well above the limit dose
(1,000 mg/kg/day). The established cRfD is 1.10 mg/kg/day therefore is
protective of these effects.
iii. Qualitative fetal susceptibility was observed in the
developmental study in rats. Maternal (decrease in body weight) and
fetal (reduced body weights, increased incidence of dilation of the
renal pelvis and skeletal variations) toxicity were observed at 1,000
mg/kg/day, the limit dose. Since fetal toxicity occurs in the presence
of maternal toxicity and a clear NOAEL of 500 mg/kg/day was
established, the established cRfD (1.10 mg/kg/day) will be protective
of these effects. The potential for reproduction toxicity was observed
in the 13-week dietary study in rats. Atrophy of seminiferous tubules
was observed in males at 12,500 ppm (900 mg/kg/day). However, the
concern for reproductive toxicity is low since effects occurred at a
high dose and a clear NOAEL of 6,250 ppm (460 mg/kg/day) was
established.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100% CT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to benzyl acetate 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
benzyl acetate.
E. Aggregate Risks and Determination of Safety Section
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime probability of acquiring cancer given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the appropriate PODs to ensure that an
adequate MOE exists.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effect resulting from a single oral exposure
was identified and no acute dietary endpoint was selected. Therefore,
benzyl acetate is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
benzyl acetate from food and water will utilize 62.9% of the cPAD for
children ages 1 to 2, the population group receiving the greatest
exposure.
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).
Benzyl acetate is likely to be used as an inert ingredient in
pesticide products that are 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 benzyl acetate. Using the
exposure assumptions described in this unit for screening-level short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 150 for children
ages 1 to 2 and 260 for adults. Because EPA's level of concern for
benzyl acetate is a MOE of 100 or below, these MOEs are not of concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Because no intermediate-term adverse effect was identified,
benzyl acetate is not expected to pose an intermediate-term risk.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in the dietary carcinogenicity studies in
mice and rats, benzyl acetate is not expected to pose a cancer risk to
humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to benzyl acetate residues.
V. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the
[[Page 7477]]
Agency is establishing an exemption from the requirement of a tolerance
without any numerical limitation.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.920 for benzyl aceetate (CAS Reg. No. 140-
11-4) when used as an inert ingredient (solvent) in pesticide
formulations applied to growing crops only.
VII. Statutory and Executive Order Reviews
This action establishes an exemption from the requirement of a
tolerance 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 exemption 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).
VIII. 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).
