Benzyl Alcohol; 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 alcohol
(CAS Reg. No. 100–51–6) when used as
an inert ingredient (adjuvant) in
pesticide formulations applied to crops
and raw agricultural commodities preand post-harvest, limited to no more
than 60% by weight in the pesticide
formulation. Landis International, Inc.,
on behalf of CJB Applied Technologies,
LLC, 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
alcohol when used in accordance with
the terms of the exemption.
DATES: This regulation is effective May
19, 2023. Objections and requests for
hearings must be received on or before
July 18, 2023, and must be filed in
accordance with the instructions
provided in 40 CFR part 178 (see also
Unit I.C. of the SUPPLEMENTARY
INFORMATION).

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):
E:\FR\FM\19MYR1.SGM
19MYR1
32134
Federal Register / Vol. 88, No. 97 / Friday, May 19, 2023 / Rules and Regulations
ddrumheller on DSK120RN23PROD with RULES1
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
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(c)(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 or exemption 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
harm 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 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 to benzyl alcohol,
including exposure resulting from the
exemption established by this action.
EPA’s assessment of exposures and risks
associated with benzyl alcohol 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 alcohol 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 alcohol exhibits low acute oral
and inhalation toxicity, while acute
dermal toxicity is moderate. Benzyl
alcohol shows none to weakly irritating
properties to the skin, but it is not a skin
sensitizer.
Based on the available repeated-dose
toxicity data on benzyl alcohol, the
central nervous system is a major target
organ in rats and mice. In rats,
mortality, staggering, labored breathing,
lethargy, and necrosis of the denta gyrus
of the hippocampus are seen at 800 mg/
kg/day following dosing in a 13-week
oral toxicity study via gavage. In mice,
lethargy is seen at 500 mg/kg/day and
staggering at 800 mg/kg/day following
dosing in a 16-day and 13-week oral
toxicity study via gavage, respectively.
Maternal (mortality, reduced body
weights, clinical signs of neurotoxicity)
and offspring (reduced bodyweight)
toxicity are seen in mice at 750 mg/kg/
day in a developmental toxicity study.
No adverse effects are seen in rats at 750
mg/kg/day in a developmental toxicity
study. Due to the neurotoxic effects seen
following dosing in the 13-week oral
toxicity studies in rats and mice at 800
mg/kg/day, the highest doses tested in
the chronic/carcinogenicity studies
were 400 and 200 mg/kg/day for rats
and mice, respectively. No systemic
toxicity or treatment related tumors
were seen in rats or mice at these doses.
Neurotoxicity studies are not
available for review. However, signs of
PO 00000
Frm 00052
Fmt 4700
Sfmt 4700
neurotoxicity are seen in mice (lethargy)
at 500 mg/kg/day following dosing in a
16-day oral toxicity study and in rats
(staggering, labored breathing, lethargy,
necrosis of the denta gyrus of the
hippocampus) and mice (staggering) at
800 mg/kg/day in a 13-week oral
toxicity study via gavage. However,
clear NOAELs were established for these
effects and the acute population
adjusted dose (aPAD) of 4 mg/kg/day
and the chronic population adjusted
dose (cPAD) of 2 mg/kg/day are
protective of the neurotoxic effects
observed at 500 mg/kg/day and 800 mg/
kg/day in the rat and mouse,
respectively. Therefore, there is no
concern for neurotoxicity.
Immunotoxicity studies are not
available for review. Thymic congestion,
hemorrhage, and atrophy were observed
at 800 mg/kg/day in rats in a 13-week
oral toxicity study via gavage. However,
a clear NOAEL was established for these
effects and the cPAD (2 mg/kg/day) is
protective of the immunotoxic effects
observed at 800 mg/kg/day. Therefore,
there is no concern for immunotoxicity.
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://

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to benzyl alcohol, EPA
considered exposure that may occur
from the existing and proposed uses of
benzyl alcohol. EPA assessed dietary
exposures from benzyl alcohol 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 after a single exposure. Such
effects were identified for benzyl
alcohol. Acute dietary (food only)
exposure and risk assessments were
conducted using the Dietary Exposure
Evaluation Model software with the
Food Commodity Intake Database
(DEEM–FCID) Version 4.02. This
software uses 2005–2010 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). The
current assessment includes every
commodity available in DEEM.
VerDate Sep<11>2014
16:30 May 18, 2023
Jkt 259001
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
using DEEM–FCID, Version 4.02, EPA
used food consumption information
from USDA’s 2005–2010 NHANES/
WWEIA. As to residue levels in food, no
residue data were submitted for benzyl
alcohol. In the absence of specific
residue data, EPA has developed an
approach which uses surrogate
information to derive upper bound
exposure estimates for the subject inert
ingredient. Upper bound exposure
estimates are based on the highest
tolerance for a given commodity from a
list of high use insecticides, herbicides,
and fungicides. 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 ‘‘Update to
D361707: Dietary Exposure and Risk
Assessments for the Inerts.’’ (12/21/
2021) and can be found at https://
www.regulations.gov in docket ID
number EPA–HQ–OPP–2018–0090.
In the dietary exposure assessment,
the Agency assumed that the residue
level of the inert ingredient would be no
higher than the highest tolerance for a
given commodity. Implicit in this
PO 00000
Frm 00053
Fmt 4700
Sfmt 4700
assumption is that there would be
similar rates of degradation (if any)
between the active and inert ingredient
and that the concentration of inert
ingredient in the scenarios leading to
these highest levels of tolerances would
be no higher than the concentration of
the active ingredient. However, to
account for the proposed uses of benzyl
alcohol up to 60% by weight in
pesticide formulations, EPA assumed a
60% concentration of benzyl alcohol in
the dietary exposure assessment.
The Agency believes the assumptions
used to estimate dietary exposures lead
to an extremely conservative assessment
of dietary risk due to a series of
compounded conservatisms. First,
assuming that the level of residue for an
inert ingredient is equal to the level of
residue for the active ingredient will
overstate exposure. The concentrations
of active ingredient in agricultural
products are generally at least 50
percent of the product and often can be
much higher. Further, pesticide
products rarely have a single inert
ingredient; rather there is generally a
combination of different inert
ingredients used which additionally
reduces the concentration of any single
E:\FR\FM\19MYR1.SGM
19MYR1
ddrumheller on DSK120RN23PROD with RULES1
32136
Federal Register / Vol. 88, No. 97 / Friday, May 19, 2023 / Rules and Regulations
inert ingredient in the pesticide product
in relation to that of the active
ingredient. Second, the conservatism of
this methodology is compounded by
EPA’s decision to assume that, for each
commodity, the active ingredient which
will serve as a guide to the potential
level of inert ingredient residues is the
active ingredient with the highest
tolerance level. This assumption
overstates residue values because it
would be highly unlikely, given the
high number of inert ingredients, that a
single inert ingredient or class of
ingredients would be present at the
level of the active ingredient in the
highest tolerance for every commodity.
Finally, a third compounding
conservatism is EPA’s assumption that
all foods contain the inert ingredient at
the highest tolerance level. In other
words, EPA assumed 100 percent of all
foods are treated with the inert
ingredient at the rate and manner
necessary to produce the highest residue
legally possible for an active ingredient.
In summary, EPA chose a very
conservative method for estimating
what level of inert residue could be on
food, then used this methodology to
choose the highest possible residue that
could be found on food and assumed
that all food contained this residue. No
consideration was given to potential
degradation between harvest and
consumption even though monitoring
data shows that tolerance level residues
are typically one to two orders of
magnitude higher than actual residues
in food when distributed in commerce.
Accordingly, although sufficient
information to quantify actual residue
levels in food is not available, the
compounding of these conservative
assumptions will lead to a significant
exaggeration of actual exposures. EPA
does not believe that this approach
underestimates exposure in the absence
of residue data.
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
alcohol, 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, for lawn and
garden pest control, indoor pest control,
VerDate Sep<11>2014
16:30 May 18, 2023
Jkt 259001
termiticides, flea and tick control on
pets and hard surface disinfection on
walls, floors, tables).
Benzyl alcohol is currently approved
for use as an inert ingredient in
antimicrobial pesticides and nonfood
use pesticides (e.g., pet spot-on
treatments; products used on lawn, turf,
or gardens) that could result in shortterm residential exposure. Although
benzyl alcohol is approved as an active
ingredient, currently there are no active
registrations for its use as an active
ingredient. Short-term residential
exposure for adults combines high-end
dermal and inhalation handler exposure
from indoor hard surface, aerosol sprays
with high-end post-application dermal
exposure from contact with treated
lawns and results in an MOE of 161.
Short-term residential exposure for
children includes total exposures
associated with contact with treated
lawns (dermal and hand-to-mouth
exposures) and results in an MOE of
540. Because EPA’s level of concern
(LOC) for benzyl alcohol is an MOE
below 100, these MOEs are not of
concern.
Intermediate-term residential
exposure for adults includes high-end
post-application dermal exposure from
contact with treated lawns and results
in an MOE of 3800. Intermediate-term
residential exposure for children
includes total exposures associated with
contact with treated lawns (dermal and
hand-to-mouth exposures) and results in
an MOE of 2,000. Because EPA’s LOC
for benzyl alcohol is an MOE below 100,
these MOEs are not of concern.
Benzyl alcohol is also used in
products such as cosmetics and
personal care products that could result
in short-, intermediate- and long-term
exposures. The International Fragrance
Association calculated a dermal
exposure of 0.042 mg/kg/day using the
reported 97.5th percentile concentration
based on the levels of the same
fragrance ingredient in ten of the most
frequently used personal care and
cosmetic products (i.e., anti-perspirant,
bath products, body lotion, eau de
toilette, face cream, fragrance cream,
hair spray, shampoo, shower gel, and
toilet soap). An inhalation exposure
level of 0.0026 mg/kg/day was
calculated based on the combined (fine
fragrances, hair sprays, antiperspirants/
deodorants, candles, aerosol air
fresheners, and reed diffusers/heated oil
plug-ins) result calculated using the
Research Institute for Fragrance
Material, Inc. (RIFM) 2-Box/MPPD in
silico models, based on the International
Fragrance Association (IFRA) survey
results for the 97.5th percentile use in
hydro alcoholics for a 60 kg individual.
PO 00000
Frm 00054
Fmt 4700
Sfmt 4700
Total systemic exposure due to use in
cosmetics and personal care products is
0.0446 mg/kg/day. The MOE is 5605.
Because EPA’s LOC for benzyl alcohol
is an MOE below 100, this MOE is not
of concern.
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 alcohol to
share a common mechanism of toxicity
with any other substances, and benzyl
alcohol 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 alcohol does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.
D. Safety Factor for Infants and
Children
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
Food Quality Protection Act safety
factor. 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.
The Agency has concluded that there
is reliable data to determine that infants
and children will be safe if the FQPA SF
of 10x is reduced to 1X for the following
reasons. The toxicity database for benzyl
alcohol is adequate, it contains
developmental toxicity studies in the
mouse and a four-generation
reproduction toxicity study in the rat.
No fetal susceptibility or reproduction
toxicity is observed in these studies.
Lethargy is observed in mice at 500 mg/

kg/day following dosing in a 16-day oral
toxicity study. In a 13-week oral toxicity
study, staggering, labored breathing,
lethargy, and necrosis of the denta gyrus
of the hippocampus were observed in
rats, and staggering was observed in
mice at 800 mg/kg/day. Thymic
congestion, hemorrhage, and atrophy
were observed in rats at 800 mg/kg/day
in a 13-week oral toxicity study.
However, clear NOAELs were
established for these effects and the
selected points of departure (PODs) are
based on the neurological effects
observed at 500 mg/kg/day and are
protective of the immunological effects
observed at 800 mg/kg/day. Therefore,
there is no concern for potential
neurotoxicity or immunotoxicity. Based
on the adequacy of the toxicity database,
the conservative nature of the exposure
assessment and the lack of concern for
prenatal and postnatal sensitivity, the
Agency has concluded that there is
reliable data to determine that infants
and children will be safe if the FQPA SF
of 10x is reduced to 1x.

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 benzyl
alcohol will occupy 74% of the aPAD
for children 1 to 2 years old, the
population group receiving the greatest
exposure.
2. Chronic risk. A chronic aggregate
risk assessment takes into account
chronic exposure estimates from dietary
consumption of food and drinking
water. Using the exposure assumptions
described in this unit for chronic
exposure, EPA has concluded that
chronic exposure to benzyl alcohol from
food and water will utilize 61% of the
cPAD for children 1 to 2 years old, 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 alcohol may 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 alcohol.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded that the
combined short-term aggregated food,
water, and residential pesticide and
non-pesticide exposures result in an
aggregate MOE of 112 for adults. Adult
residential pesticide exposure combines
high-end dermal and inhalation handler
exposure from indoor hard surface
aerosol spray with high-end postapplication dermal exposure from
contact with treated lawns. EPA has
concluded the combined short-term
aggregated food, water, and residential
pesticide and non-pesticide exposures
result in an aggregate MOE of 123 for
children. Children’s residential
pesticide exposure includes total
exposures associated with contact with
treated lawns (dermal and hand-tomouth exposures). Because EPA’s LOC
for benzyl alcohol is an MOE below 100,
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).
Benzyl alcohol may be used as an
inert ingredient in pesticide products
that are registered for uses that could
result in intermediate-term residential
exposure, and the Agency has
determined that it is appropriate to
aggregate chronic exposure through food
and water with intermediate-term
residential exposures to benzyl alcohol.
Using the exposure assumptions
described in this unit for intermediateterm exposures, EPA has concluded that
the intermediate-term aggregated food,
water, and residential exposures result
in an aggregate MOE of 337 for adults.
Adult residential pesticide exposure
combines high-end dermal and
inhalation handler exposure from
indoor hard surface aerosol spray with
a high-end post-application dermal
exposure from contact with treated
lawns. EPA has concluded the
combined intermediate-term aggregated
food, water, and residential pesticide
and non-pesticide exposures result in an
aggregate MOE of 147 for children.
Children’s residential exposure includes
total exposures associated with contact

with treated lawns (dermal and hand-tomouth exposures). Because EPA’s LOC
for benzyl alcohol is an MOE below 100,
these MOEs are not of concern.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in adequate
rodent carcinogenicity studies, benzyl
alcohol is not expected to pose a cancer
risk to humans.
6. Determination of safety. Based on
the risk assessments and information
described above, 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
alcohol residues. More detailed
information on this action can be found
in the document titled ‘‘Benzyl Alcohol
Human Health Risk Assessment and
Ecological Effects Assessment to
Support an Exemption from the
Requirement of a Tolerance When Used
as an Inert Ingredient in Pesticide
Formulations’’ in docket ID EPA–HQ–
OPP–2021–0173.
V. Other Considerations
Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is not establishing a numerical
tolerance for residues of benzyl alcohol
in or on any food commodities. EPA is
establishing a limitation on the amount
of benzyl alcohol that may be used in
pesticide formulations. This limitation
will be enforced through the pesticide
registration process under the Federal
Insecticide, Fungicide, and Rodenticide
Act (‘‘FIFRA’’), 7 U.S.C. 136 et seq. EPA
will not register any pesticide
formulation for food use that exceeds
60% benzyl alcohol in the final
pesticide formulation.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
for residues of benzyl alcohol (CAS Reg.
No. 100–51–6) when used as an inert
ingredient (adjuvant) in pesticide
formulations applied to crops and raw
agricultural commodities pre- and postharvest under 40 CFR 180.910, limited
to no more than 60% by weight in the
pesticide formulation.
VII. Statutory and Executive Order
Reviews
This action establishes a tolerance
exemption 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
E:\FR\FM\19MYR1.SGM
19MYR1
32138
Federal Register / Vol. 88, No. 97 / Friday, May 19, 2023 / Rules and Regulations
‘‘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 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).

Benzyl Alcohol; Exemption From the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of benzyl alcohol (CAS Reg. No. 100-51-6)
when used as an inert ingredient (adjuvant) in pesticide formulations
applied to crops and raw agricultural commodities pre- and post-
harvest, limited to no more than 60% by weight in the pesticide
formulation. Landis International, Inc., on behalf of CJB Applied
Technologies, LLC, 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 alcohol when used in accordance with the terms of
the exemption.
DATES: This regulation is effective May 19, 2023. Objections and
requests for hearings must be received on or before July 18, 2023, and
must be filed in accordance with the instructions provided in 40 CFR
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

harvest, limited to no more than 60% by weight in the pesticide
formulation. That document referenced a summary of the petition
prepared by Landis International, Inc., on behalf of CJB Applied
Technologies, LLC, 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):
[[Page 32134]]
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 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(c)(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 or exemption 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 harm 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 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 to benzyl alcohol, including
exposure resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with benzyl alcohol
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 alcohol 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 alcohol exhibits low acute oral and inhalation toxicity,
while acute dermal toxicity is moderate. Benzyl alcohol shows none to
weakly irritating properties to the skin, but it is not a skin
sensitizer.
Based on the available repeated-dose toxicity data on benzyl
alcohol, the central nervous system is a major target organ in rats and
mice. In rats, mortality, staggering, labored breathing, lethargy, and
necrosis of the denta gyrus of the hippocampus are seen at 800 mg/kg/
day following dosing in a 13-week oral toxicity study via gavage. In
mice, lethargy is seen at 500 mg/kg/day and staggering at 800 mg/kg/day
following dosing in a 16-day and 13-week oral toxicity study via
gavage, respectively. Maternal (mortality, reduced body weights,
clinical signs of neurotoxicity) and offspring (reduced bodyweight)
toxicity are seen in mice at 750 mg/kg/day in a developmental toxicity
study. No adverse effects are seen in rats at 750 mg/kg/day in a
developmental toxicity study. Due to the neurotoxic effects seen
following dosing in the 13-week oral toxicity studies in rats and mice
at 800 mg/kg/day, the highest doses tested in the chronic/
carcinogenicity studies were 400 and 200 mg/kg/day for rats and mice,
respectively. No systemic toxicity or treatment related tumors were
seen in rats or mice at these doses.
Neurotoxicity studies are not available for review. However, signs
of neurotoxicity are seen in mice (lethargy) at 500 mg/kg/day following
dosing in a 16-day oral toxicity study and in rats (staggering, labored
breathing, lethargy, necrosis of the denta gyrus of the hippocampus)
and mice (staggering) at 800 mg/kg/day in a 13-week oral toxicity study
via gavage. However, clear NOAELs were established for these effects
and the acute population adjusted dose (aPAD) of 4 mg/kg/day and the
chronic population adjusted dose (cPAD) of 2 mg/kg/day are protective
of the neurotoxic effects observed at 500 mg/kg/day and 800 mg/kg/day
in the rat and mouse, respectively. Therefore, there is no concern for
neurotoxicity.
Immunotoxicity studies are not available for review. Thymic
congestion, hemorrhage, and atrophy were observed at 800 mg/kg/day in
rats in a 13-week oral toxicity study via gavage. However, a clear
NOAEL was established for these effects and the cPAD (2 mg/kg/day) is
protective of the immunotoxic effects observed at 800 mg/kg/day.
Therefore, there is no concern for immunotoxicity.
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/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to benzyl alcohol, EPA considered exposure that may occur from
the existing and proposed uses of benzyl alcohol. EPA assessed dietary
exposures from benzyl alcohol 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
after a single exposure. Such effects were identified for benzyl
alcohol. Acute dietary (food only) exposure and risk assessments were
conducted using the Dietary Exposure Evaluation Model software with the
Food Commodity Intake Database (DEEM-FCID) Version 4.02. This software
uses 2005-2010 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). The current assessment
includes every commodity available in DEEM.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment using DEEM-FCID, Version 4.02, EPA used food consumption
information from USDA's 2005-2010 NHANES/WWEIA. As to residue levels in
food, no residue data were submitted for benzyl alcohol. In the absence
of specific residue data, EPA has developed an approach which uses
surrogate information to derive upper bound exposure estimates for the
subject inert ingredient. Upper bound exposure estimates are based on
the highest tolerance for a given commodity from a list of high use
insecticides, herbicides, and fungicides. 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 ``Update to
D361707: Dietary Exposure and Risk Assessments for the Inerts.'' (12/
21/2021) and can be found at https://www.regulations.gov in docket ID
number EPA-HQ-OPP-2018-0090.
In the dietary exposure assessment, the Agency assumed that the
residue level of the inert ingredient would be no higher than the
highest tolerance for a given commodity. Implicit in this assumption is
that there would be similar rates of degradation (if any) between the
active and inert ingredient and that the concentration of inert
ingredient in the scenarios leading to these highest levels of
tolerances would be no higher than the concentration of the active
ingredient. However, to account for the proposed uses of benzyl alcohol
up to 60% by weight in pesticide formulations, EPA assumed a 60%
concentration of benzyl alcohol in the dietary exposure assessment.
The Agency believes the assumptions used to estimate dietary
exposures lead to an extremely conservative assessment of dietary risk
due to a series of compounded conservatisms. First, assuming that the
level of residue for an inert ingredient is equal to the level of
residue for the active ingredient will overstate exposure. The
concentrations of active ingredient in agricultural products are
generally at least 50 percent of the product and often can be much
higher. Further, pesticide products rarely have a single inert
ingredient; rather there is generally a combination of different inert
ingredients used which additionally reduces the concentration of any
single
[[Page 32136]]
inert ingredient in the pesticide product in relation to that of the
active ingredient. Second, the conservatism of this methodology is
compounded by EPA's decision to assume that, for each commodity, the
active ingredient which will serve as a guide to the potential level of
inert ingredient residues is the active ingredient with the highest
tolerance level. This assumption overstates residue values because it
would be highly unlikely, given the high number of inert ingredients,
that a single inert ingredient or class of ingredients would be present
at the level of the active ingredient in the highest tolerance for
every commodity. Finally, a third compounding conservatism is EPA's
assumption that all foods contain the inert ingredient at the highest
tolerance level. In other words, EPA assumed 100 percent of all foods
are treated with the inert ingredient at the rate and manner necessary
to produce the highest residue legally possible for an active
ingredient. In summary, EPA chose a very conservative method for
estimating what level of inert residue could be on food, then used this
methodology to choose the highest possible residue that could be found
on food and assumed that all food contained this residue. No
consideration was given to potential degradation between harvest and
consumption even though monitoring data shows that tolerance level
residues are typically one to two orders of magnitude higher than
actual residues in food when distributed in commerce.
Accordingly, although sufficient information to quantify actual
residue levels in food is not available, the compounding of these
conservative assumptions will lead to a significant exaggeration of
actual exposures. EPA does not believe that this approach
underestimates exposure in the absence of residue data.
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 alcohol, 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, for lawn and garden pest control, indoor pest control,
termiticides, flea and tick control on pets and hard surface
disinfection on walls, floors, tables).
Benzyl alcohol is currently approved for use as an inert ingredient
in antimicrobial pesticides and nonfood use pesticides (e.g., pet spot-
on treatments; products used on lawn, turf, or gardens) that could
result in short-term residential exposure. Although benzyl alcohol is
approved as an active ingredient, currently there are no active
registrations for its use as an active ingredient. Short-term
residential exposure for adults combines high-end dermal and inhalation
handler exposure from indoor hard surface, aerosol sprays with high-end
post-application dermal exposure from contact with treated lawns and
results in an MOE of 161. Short-term residential exposure for children
includes total exposures associated with contact with treated lawns
(dermal and hand-to-mouth exposures) and results in an MOE of 540.
Because EPA's level of concern (LOC) for benzyl alcohol is an MOE below
100, these MOEs are not of concern.
Intermediate-term residential exposure for adults includes high-end
post-application dermal exposure from contact with treated lawns and
results in an MOE of 3800. Intermediate-term residential exposure for
children includes total exposures associated with contact with treated
lawns (dermal and hand-to-mouth exposures) and results in an MOE of
2,000. Because EPA's LOC for benzyl alcohol is an MOE below 100, these
MOEs are not of concern.
Benzyl alcohol is also used in products such as cosmetics and
personal care products that could result in short-, intermediate- and
long-term exposures. The International Fragrance Association calculated
a dermal exposure of 0.042 mg/kg/day using the reported 97.5th
percentile concentration based on the levels of the same fragrance
ingredient in ten of the most frequently used personal care and
cosmetic products (i.e., anti-perspirant, bath products, body lotion,
eau de toilette, face cream, fragrance cream, hair spray, shampoo,
shower gel, and toilet soap). An inhalation exposure level of 0.0026
mg/kg/day was calculated based on the combined (fine fragrances, hair
sprays, antiperspirants/deodorants, candles, aerosol air fresheners,
and reed diffusers/heated oil plug-ins) result calculated using the
Research Institute for Fragrance Material, Inc. (RIFM) 2-Box/MPPD in
silico models, based on the International Fragrance Association (IFRA)
survey results for the 97.5th percentile use in hydro alcoholics for a
60 kg individual. Total systemic exposure due to use in cosmetics and
personal care products is 0.0446 mg/kg/day. The MOE is 5605. Because
EPA's LOC for benzyl alcohol is an MOE below 100, this MOE is not of
concern.
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 alcohol to share a common mechanism of
toxicity with any other substances, and benzyl alcohol 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 alcohol does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's website at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
D. Safety Factor for Infants and Children
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 Food Quality Protection
Act safety factor. 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.
The Agency has concluded that there is reliable data to determine
that infants and children will be safe if the FQPA SF of 10x is reduced
to 1X for the following reasons. The toxicity database for benzyl
alcohol is adequate, it contains developmental toxicity studies in the
mouse and a four-generation reproduction toxicity study in the rat. No
fetal susceptibility or reproduction toxicity is observed in these
studies. Lethargy is observed in mice at 500 mg/
[[Page 32137]]
kg/day following dosing in a 16-day oral toxicity study. In a 13-week
oral toxicity study, staggering, labored breathing, lethargy, and
necrosis of the denta gyrus of the hippocampus were observed in rats,
and staggering was observed in mice at 800 mg/kg/day. Thymic
congestion, hemorrhage, and atrophy were observed in rats at 800 mg/kg/
day in a 13-week oral toxicity study. However, clear NOAELs were
established for these effects and the selected points of departure
(PODs) are based on the neurological effects observed at 500 mg/kg/day
and are protective of the immunological effects observed at 800 mg/kg/
day. Therefore, there is no concern for potential neurotoxicity or
immunotoxicity. Based on the adequacy of the toxicity database, the
conservative nature of the exposure assessment and the lack of concern
for prenatal and postnatal sensitivity, the Agency has concluded that
there is reliable data to determine that infants and children will be
safe if the FQPA SF of 10x is reduced to 1x.
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 benzyl alcohol will occupy 74% of the aPAD for children 1 to 2 years
old, the population group receiving the greatest exposure.
2. Chronic risk. A chronic aggregate risk assessment takes into
account chronic exposure estimates from dietary consumption of food and
drinking water. Using the exposure assumptions described in this unit
for chronic exposure, EPA has concluded that chronic exposure to benzyl
alcohol from food and water will utilize 61% of the cPAD for children 1
to 2 years old, 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 alcohol may 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 alcohol.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded that the combined short-term
aggregated food, water, and residential pesticide and non-pesticide
exposures result in an aggregate MOE of 112 for adults. Adult
residential pesticide exposure combines high-end dermal and inhalation
handler exposure from indoor hard surface aerosol spray with high-end
post-application dermal exposure from contact with treated lawns. EPA
has concluded the combined short-term aggregated food, water, and
residential pesticide and non-pesticide exposures result in an
aggregate MOE of 123 for children. Children's residential pesticide
exposure includes total exposures associated with contact with treated
lawns (dermal and hand-to-mouth exposures). Because EPA's LOC for
benzyl alcohol is an MOE below 100, 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).
Benzyl alcohol may be used as an inert ingredient in pesticide
products that are registered for uses that could result in
intermediate-term residential exposure, and the Agency has determined
that it is appropriate to aggregate chronic exposure through food and
water with intermediate-term residential exposures to benzyl alcohol.
Using the exposure assumptions described in this unit for
intermediate-term exposures, EPA has concluded that the intermediate-
term aggregated food, water, and residential exposures result in an
aggregate MOE of 337 for adults. Adult residential pesticide exposure
combines high-end dermal and inhalation handler exposure from indoor
hard surface aerosol spray with a high-end post-application dermal
exposure from contact with treated lawns. EPA has concluded the
combined intermediate-term aggregated food, water, and residential
pesticide and non-pesticide exposures result in an aggregate MOE of 147
for children. Children's residential exposure includes total exposures
associated with contact with treated lawns (dermal and hand-to-mouth
exposures). Because EPA's LOC for benzyl alcohol is an MOE below 100,
these MOEs are not of concern.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in adequate rodent carcinogenicity studies,
benzyl alcohol is not expected to pose a cancer risk to humans.
6. Determination of safety. Based on the risk assessments and
information described above, 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 alcohol
residues. More detailed information on this action can be found in the
document titled ``Benzyl Alcohol Human Health Risk Assessment and
Ecological Effects Assessment to Support an Exemption from the
Requirement of a Tolerance When Used as an Inert Ingredient in
Pesticide Formulations'' in docket ID EPA-HQ-OPP-2021-0173.
V. Other Considerations
Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is not establishing a numerical tolerance for residues of
benzyl alcohol in or on any food commodities. EPA is establishing a
limitation on the amount of benzyl alcohol that may be used in
pesticide formulations. This limitation will be enforced through the
pesticide registration process under the Federal Insecticide,
Fungicide, and Rodenticide Act (``FIFRA''), 7 U.S.C. 136 et seq. EPA
will not register any pesticide formulation for food use that exceeds
60% benzyl alcohol in the final pesticide formulation.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established for residues of benzyl alcohol (CAS Reg. No. 100-51-6) when
used as an inert ingredient (adjuvant) in pesticide formulations
applied to crops and raw agricultural commodities pre- and post-harvest
under 40 CFR 180.910, limited to no more than 60% by weight in the
pesticide formulation.
VII. Statutory and Executive Order Reviews
This action establishes a tolerance exemption 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
[[Page 32138]]
``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
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).
