II. Petition for Exemption
In the Federal Register of May 19,
2010 (75 FR 28009)(FRL–9153–1), EPA
issued a notice pursuant to section 408
of FFDCA, 21 U.S.C. 346a, announcing
the filing of a pesticide petition (PP
0E7686)(75 FR 28012) by Dow
AgroSciences, LLC, 9330 Zionsville
Road, Indianapolis, IN, 46268. The
petition requested that 40 CFR 180.920
be amended by establishing an
exemption from the requirement of a
tolerance for residues of choline
hydroxide (CAS Reg. No. 123–41–1)
when used as an inert ingredient (a
neutralizer) in acidic herbicide
formulations applied preharvest. That
notice referenced a summary of the
petition prepared by Dow AgroSciences,
the petitioner, which is available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
Based upon review of the data
supporting the petition, EPA has
modified the exemption requested to
pesticide formulations rather than
herbicide formulations.
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
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
VerDate Mar<15>2010
18:02 Aug 31, 2010
Jkt 220001
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 section 408(c)(2)(A)
of FFDCA, 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 choline
hydroxide including exposure resulting
from the exemption established by this
action. EPA’s assessment of exposures
and risks associated with choline
hydroxide 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
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
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 choline hydroxide 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.
No toxicity data are available for
choline hydroxide. Upon contact with
water, choline hydroxide is expected to
dissociate into the cationic form
(choline) and the anionic form
(hydroxide ions). Choline hydroxide
added to an acidic herbicide, forms an
herbicide-choline salt product which
will be sold in concentrate form. When
the concentrate is mixed with water
prior to application, the salt dissociates
to the cationic form (choline). Choline
cation therefore, is the moiety of
interest. Since no toxicological studies
are available in the literature, studies on
choline chloride and other salts were
used for evaluating the risk from
exposure to choline hydroxide.
According to the Organisation for
Economic Co-operation and
Development (OECD) due to its caustic
nature (pH 14), acute toxicity testing of
choline hydroxide would not be
appropriate (OECD Guidelines for the
Testing of Chemicals, Procedure 404
(2002); OECD Guideline for testing of
Chemicals, Procedure, 405, 2002).
Choline hydroxide is known as a skin,
eye and respiratory irritant. It should be
noted here that there will be essentially
no contact with choline hydroxide in an
end-use product.
As was discussed above, the hydroxy
moiety dissociates and essentially
ceases to exist upon mixing with water
in preparation for application and in the
body. The choline cation is what is left
to be considered. The Agency has
extensively assessed the effects of
choline upon human systems and the
environment. A summary of the
Agency’s findings are recorded in: Final
Rule, Choline Chloride; Exemption from
the Requirement of a Tolerance, EPA–
HQ–OPP–2008–0671; FRL–8802–4 (75

Agency’s assessment are found in:

the human diet and acts as a precursor
to acetylcholine, phospholipids, and the
methyl donor betaine. It is important for
the structural integrity of cell
membranes, cholinergic

neurotransmission, transmembrane
signaling, methyl metabolism, and lipid
and cholesterol transport and
metabolism.
Choline was officially made an
‘‘essential nutrient’’ in 1998 and
adequate intake (AI) levels were
established (women - 425 milligrams/
day (mg/day), pregnant women - 450
mg/day, men and lactating women - 550
mg/day). The Daily Upper Intake Level
for choline is 3.5 grams (g) for adults.
Research indicates that many
individuals are not getting enough
choline, with daily intake levels far
below the AI.
One study in mice evaluated the
impact of 200 milligram/kilogram/day
(mg/kg/day) choline chloride given
orally or intranasally for 28 days. No
adverse effects were observed with
regards to body weight, food and water
consumption, hematology, clinical
biochemistry, or histopathology of
various organs (lung, heart, liver,
spleen, and kidney). Results from
intranasal exposure to choline chloride
were comparable with their respective
controls and to other treatment groups.
The no-observed-adverse-effect-level
(NOAEL) for oral and intranasally
administered choline chloride is ≥ 200
mg/kg/day.
A 72–week feeding study was
conducted in rats administered 500 mg/
kg/day of choline chloride; the animals
were observed for 30 weeks post
exposure. There were no significant
differences between the control and
treated group in relation to body
weights, relative liver weight, survival
rates, and the number of neoplastic liver
nodules, hepatocellular carcinomas,
lung tumors, leukemia, or other tumors.
This study resulted in a NOAEL of 500
mg/kg/day (the highest dose tested).
Choline is a precursor to the vital
neurotransmitter acetylcholine. Studies
show that choline has beneficial effects
on the nervous system and memory.
Choline is necessary to promote proper
development in the fetus and infant and
prevent cognitive problems. Choline
chloride is not expected to cause
neurotoxicity and it is not a known
endocrine disruptor nor are its
metabolites related to any class of
known endocrine disruptors. Based on
the results of the in vitro and in vivo
studies the Agency concluded that
choline chloride is not expected to be
carcinogenic or mutagenic.
Since the 1930’s choline chloride has
been used as a widespread nutrient in
animal feed without adverse effects
reported on fertility or teratogenicity.
The Food and Drug Administration
(FDA) requires choline be added to nonmilk based infant formulas at a
VerDate Mar<15>2010
18:02 Aug 31, 2010
Jkt 220001
minimum concentration of 7 mg for
every 100 kilocalories (21 CFR 107.100).
Although one study did show
developmental effects, they were only
seen at very high doses (≥ 4,160 mg/kg/
day) and only in the presence of
maternal toxicity. There were no
observed adverse effects for both
mothers and pups exposed to 1,250 mg/
kg/day. Based on this information the
Agency concluded that choline
chloride, when used as an inert
ingredient, will not cause reproductive
or developmental toxicity and therefore,
does not anticipate an increased risk to
infants and children.
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 the NOAEL and the
LOAEL of concern are identified.
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 nonthreshold 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.
No toxicological endpoints have been
identified in the available toxicological
database. Considering the low toxicity
of choline chloride, its natural
occurrence, the body’s ability to
synthesize the nutrient, and the
relatively small amount in the
formulation, it is not necessary to
conduct a quantitative risk assessment.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to choline hydroxide, EPA
considered exposure under the
proposed exemption from the
requirement of a tolerance. EPA
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
53579
assessed dietary exposures from choline
hydroxide in food as follows:
Choline is a natural component of a
variety of commonly consumed foods
(e.g. (per 100 g food) - eggs (251 mg),
wheat germ (152 mg), bacon (125 mg),
dried soybeans (116 mg), pork (103 mg),
cod (83 mg), beef (80 mg), chicken (70
mg), and salmon (65 mg)) United States
Department of Agriculture (USDA,
2004). It has been added as a
supplement to infant formula in the
United States for decades (Politizer
Shronts, 1997). In addition to dietary
consumption, choline is made
endogenously in the human body.
Humans are currently exposed to
choline on a daily basis through
commonly eaten foods (both naturally
occurring and when added as a nutrient)
and through the bodies natural ability to
synthesize the nutrient. It is unlikely
that the exposure from choline chloride,
when used as an inert ingredient
applied preharvest to food commodities,
will significantly increase the natural
concentration of choline present in
foods. Because of its high water
solubility it is expected that most of the
inert will be washed from the plant
prior to consumption. Once in water, it
will be broken into in a quaternary
hydroxyl alkylammonium ion and a
chloride ion.
2. Dietary exposure from drinking
water. A quantitative drinking water
assessment was not performed because
it is expected that upon contact with
water choline chloride will be broken
into a quaternary hydroxyl
alkylammonium ion and a chloride ion.
Therefore, direct contact with choline
hydroxide is not expected through
drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., textiles (clothing and diapers),
carpets, swimming pools, and hard
surface disinfection on walls, floors,
tables).
Occupational exposure to choline
chloride is expected via dermal and
inhalation routes of exposure. Since an
endpoint for risk assessment was not
identified, a quantitative occupational
and residential exposure assessment for
choline hydroxide was not conducted.
Residential (dermal and inhalation)
exposures from home garden uses are
possible.
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
E:\FR\FM\01SER1.SGM
01SER1
53580
Federal Register / Vol. 75, No. 169 / Wednesday, September 1, 2010 / Rules and Regulations
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found choline hydroxide
to share a common mechanism of
toxicity with any other substances, and
choline hydroxide does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that choline hydroxide 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/pesticides/cumulative.

D. Safety Factor for Infants and
Children
There is no evidence of increased
susceptibility in the available
developmental toxicity study in mice.
Choline is a natural component of a
variety of commonly consumed foods. It
has been added as a supplement to
infant formula in the United States for
decades. In addition to dietary
consumption of choline, choline is
made endogenously in the human body.
Choline is a precursor to the vital
neurotransmitter acetylcholine. Studies
show that choline has beneficial effects
on the nervous system and memory.
Choline is necessary to promote proper
development in the fetus and infant and
prevent cognitive problems. Choline
hydroxide is not expected to cause
neurotoxicity. Exposure to choline
hydroxide is not expected to
significantly increase the pre-existing
levels found in commonly eaten foods.
Due to the negligible anticipated crop
residues and subsequent exposure, the
low toxicity of the chemical and its
metabolites, and the body’s need for
choline from a dietary source, EPA has
determined that a quantitative risk
assessment using safety factors is
unnecessary. For the same reason, no
additional safety factor for the
protection of infants and children is
needed.
E. Aggregate Risks and Determination of
Safety
Taking into consideration all available
information on choline hydroxide, EPA
has determined that there is a
reasonable certainty that no harm to any
population subgroup will result from
aggregate exposure to choline hydroxide
under reasonably foreseeable
circumstances.
In addition to its low toxicity,
exposure to choline hydroxide will be
VerDate Mar<15>2010
18:02 Aug 31, 2010
Jkt 220001
limited. The expected exposure
pathway is via the oral and the dermal
routes. Humans are currently exposed to
choline on a daily basis through
commonly eaten foods (both naturally
occurring and when added as a nutrient)
and through the bodies natural ability to
synthesize the nutrient. It is unlikely
that the exposure from choline
hydroxide, when used as an inert
ingredient applied preharvest to food
commodities, will significantly increase
the natural concentration of choline and
chloride in foods. Choline is also found
naturally in the environment.
Taking into consideration all available
information on choline hydroxide, it has
been determined that there is a
reasonable certainty that no harm to any
population subgroup, including infants
and children, will result from aggregate
exposure to this chemical. Therefore,
the establishment of an exemption from
tolerance under 40 CFR 180.920 for
residues of choline hydroxide when
used as an inert ingredient in pesticide
formulations applied to preharvest
applications of pesticides, is safe under
FFDCA section 408.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is establishing an exemption
from the requirement of a tolerance
without any numerical limitation.
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint U.N.
Food and Agriculture Organization/
World Health Organization food
standards program, and it is recognized
as an international food safety
standards-setting organization in trade
agreements to which the United States
is a party. EPA may establish a tolerance
that is different from a Codex MRL;
however, FFDCA section 408(b)(4)
requires that EPA explain the reasons
for departing from the Codex level.
The Codex has not established a MRL
for choline hydroxide.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.920 for choline

hydroxide (CAS Reg. No. 123–41–1)
when used as an inert ingredient (in
acidic herbicides to act as a neutralizer])
in pesticide formulations applied to
preharvest applications.
VII. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled Regulatory
Planning and Review (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order
12898, entitled Federal Actions to
Address Environmental Justice in
Minority Populations and Low-Income
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. 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

to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary

VIII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of this final rule in the
Federal Register. This final rule is not
a ‘‘major rule’’ as defined by 5 U.S.C.
804(2).

II. Petition for Exemption
In the Federal Register of May 19, 2010 (75 FR 28009)(FRL-9153-1),
EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a,
announcing the filing of a pesticide petition (PP 0E7686)(75 FR 28012)
by Dow AgroSciences, LLC, 9330 Zionsville Road, Indianapolis, IN,
46268. The petition requested that 40 CFR 180.920 be amended by
establishing an exemption from the requirement of a tolerance for
residues of choline hydroxide (CAS Reg. No. 123-41-1) when used as an
inert ingredient (a neutralizer) in acidic herbicide formulations
applied preharvest. That notice referenced a summary of the petition
prepared by Dow AgroSciences, the petitioner, which is available in the
docket, https://www.regulations.gov. There were no comments received in
response to the notice of filing.
Based upon review of the data supporting the petition, EPA has
modified the exemption requested to pesticide formulations rather than
herbicide formulations.
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 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 section 408(c)(2)(A) of FFDCA, 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 choline hydroxide including
exposure resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with choline hydroxide
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 choline hydroxide 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.
No toxicity data are available for choline hydroxide. Upon contact
with water, choline hydroxide is expected to dissociate into the
cationic form (choline) and the anionic form (hydroxide ions). Choline
hydroxide added to an acidic herbicide, forms an herbicide-choline salt
product which will be sold in concentrate form. When the concentrate is
mixed with water prior to application, the salt dissociates to the
cationic form (choline). Choline cation therefore, is the moiety of
interest. Since no toxicological studies are available in the
literature, studies on choline chloride and other salts were used for
evaluating the risk from exposure to choline hydroxide.
According to the Organisation for Economic Co-operation and
Development (OECD) due to its caustic nature (pH 14), acute toxicity
testing of choline hydroxide would not be appropriate (OECD Guidelines
for the Testing of Chemicals, Procedure 404 (2002); OECD Guideline for
testing of Chemicals, Procedure, 405, 2002). Choline hydroxide is known
as a skin, eye and respiratory irritant. It should be noted here that
there will be essentially no contact with choline hydroxide in an end-
use product.
As was discussed above, the hydroxy moiety dissociates and
essentially ceases to exist upon mixing with water in preparation for
application and in the body. The choline cation is what is left to be
considered. The Agency has extensively assessed the effects of choline
upon human systems and the environment. A summary of the Agency's
findings are recorded in: Final Rule, Choline Chloride; Exemption from
the Requirement of a Tolerance, EPA-HQ-OPP-2008-0671; FRL-8802-4 (75 FR
760, January 6, 2010). Details of the Agency's assessment are found in:
Decision Document for Petition Number 8E7387; Choline Chloride, CAS
Reg. No 67-48-1; Memorandum, D. Sunderland, RD/OPP, 16 OCT 2009.
Choline is an essential component of the human diet and acts as a
precursor to acetylcholine, phospholipids, and the methyl donor
betaine. It is important for the structural integrity of cell
membranes, cholinergic
[[Page 53579]]
neurotransmission, transmembrane signaling, methyl metabolism, and
lipid and cholesterol transport and metabolism.
Choline was officially made an ``essential nutrient'' in 1998 and
adequate intake (AI) levels were established (women - 425 milligrams/
day (mg/day), pregnant women - 450 mg/day, men and lactating women -
550 mg/day). The Daily Upper Intake Level for choline is 3.5 grams (g)
for adults. Research indicates that many individuals are not getting
enough choline, with daily intake levels far below the AI.
One study in mice evaluated the impact of 200 milligram/kilogram/
day (mg/kg/day) choline chloride given orally or intranasally for 28
days. No adverse effects were observed with regards to body weight,
food and water consumption, hematology, clinical biochemistry, or
histopathology of various organs (lung, heart, liver, spleen, and
kidney). Results from intranasal exposure to choline chloride were
comparable with their respective controls and to other treatment
groups. The no-observed-adverse-effect-level (NOAEL) for oral and
intranasally administered choline chloride is >= 200 mg/kg/day.
A 72-week feeding study was conducted in rats administered 500 mg/
kg/day of choline chloride; the animals were observed for 30 weeks post
exposure. There were no significant differences between the control and
treated group in relation to body weights, relative liver weight,
survival rates, and the number of neoplastic liver nodules,
hepatocellular carcinomas, lung tumors, leukemia, or other tumors. This
study resulted in a NOAEL of 500 mg/kg/day (the highest dose tested).
Choline is a precursor to the vital neurotransmitter acetylcholine.
Studies show that choline has beneficial effects on the nervous system
and memory. Choline is necessary to promote proper development in the
fetus and infant and prevent cognitive problems. Choline chloride is
not expected to cause neurotoxicity and it is not a known endocrine
disruptor nor are its metabolites related to any class of known
endocrine disruptors. Based on the results of the in vitro and in vivo
studies the Agency concluded that choline chloride is not expected to
be carcinogenic or mutagenic.
Since the 1930's choline chloride has been used as a widespread
nutrient in animal feed without adverse effects reported on fertility
or teratogenicity. The Food and Drug Administration (FDA) requires
choline be added to non-milk based infant formulas at a minimum
concentration of 7 mg for every 100 kilocalories (21 CFR 107.100).
Although one study did show developmental effects, they were only seen
at very high doses (>= 4,160 mg/kg/day) and only in the presence of
maternal toxicity. There were no observed adverse effects for both
mothers and pups exposed to 1,250 mg/kg/day. Based on this information
the Agency concluded that choline chloride, when used as an inert
ingredient, will not cause reproductive or developmental toxicity and
therefore, does not anticipate an increased risk to infants and
children.
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 the NOAEL and the LOAEL of concern are
identified. 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.
No toxicological endpoints have been identified in the available
toxicological database. Considering the low toxicity of choline
chloride, its natural occurrence, the body's ability to synthesize the
nutrient, and the relatively small amount in the formulation, it is not
necessary to conduct a quantitative risk assessment.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to choline hydroxide, EPA considered exposure under the
proposed exemption from the requirement of a tolerance. EPA assessed
dietary exposures from choline hydroxide in food as follows:
Choline is a natural component of a variety of commonly consumed
foods (e.g. (per 100 g food) - eggs (251 mg), wheat germ (152 mg),
bacon (125 mg), dried soybeans (116 mg), pork (103 mg), cod (83 mg),
beef (80 mg), chicken (70 mg), and salmon (65 mg)) United States
Department of Agriculture (USDA, 2004). It has been added as a
supplement to infant formula in the United States for decades
(Politizer Shronts, 1997). In addition to dietary consumption, choline
is made endogenously in the human body.
Humans are currently exposed to choline on a daily basis through
commonly eaten foods (both naturally occurring and when added as a
nutrient) and through the bodies natural ability to synthesize the
nutrient. It is unlikely that the exposure from choline chloride, when
used as an inert ingredient applied preharvest to food commodities,
will significantly increase the natural concentration of choline
present in foods. Because of its high water solubility it is expected
that most of the inert will be washed from the plant prior to
consumption. Once in water, it will be broken into in a quaternary
hydroxyl alkylammonium ion and a chloride ion.
2. Dietary exposure from drinking water. A quantitative drinking
water assessment was not performed because it is expected that upon
contact with water choline chloride will be broken into a quaternary
hydroxyl alkylammonium ion and a chloride ion. Therefore, direct
contact with choline hydroxide is not expected through drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., textiles (clothing and diapers), carpets, swimming
pools, and hard surface disinfection on walls, floors, tables).
Occupational exposure to choline chloride is expected via dermal
and inhalation routes of exposure. Since an endpoint for risk
assessment was not identified, a quantitative occupational and
residential exposure assessment for choline hydroxide was not
conducted. Residential (dermal and inhalation) exposures from home
garden uses are possible.
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
[[Page 53580]]
cumulative effects of a particular pesticide's residues and ``other
substances that have a common mechanism of toxicity.''
EPA has not found choline hydroxide to share a common mechanism of
toxicity with any other substances, and choline hydroxide does not
appear to produce a toxic metabolite produced by other substances. For
the purposes of this tolerance action, therefore, EPA has assumed that
choline hydroxide 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/pesticides/cumulative.
D. Safety Factor for Infants and Children
There is no evidence of increased susceptibility in the available
developmental toxicity study in mice. Choline is a natural component of
a variety of commonly consumed foods. It has been added as a supplement
to infant formula in the United States for decades. In addition to
dietary consumption of choline, choline is made endogenously in the
human body. Choline is a precursor to the vital neurotransmitter
acetylcholine. Studies show that choline has beneficial effects on the
nervous system and memory. Choline is necessary to promote proper
development in the fetus and infant and prevent cognitive problems.
Choline hydroxide is not expected to cause neurotoxicity. Exposure to
choline hydroxide is not expected to significantly increase the pre-
existing levels found in commonly eaten foods. Due to the negligible
anticipated crop residues and subsequent exposure, the low toxicity of
the chemical and its metabolites, and the body's need for choline from
a dietary source, EPA has determined that a quantitative risk
assessment using safety factors is unnecessary. For the same reason, no
additional safety factor for the protection of infants and children is
needed.
E. Aggregate Risks and Determination of Safety
Taking into consideration all available information on choline
hydroxide, EPA has determined that there is a reasonable certainty that
no harm to any population subgroup will result from aggregate exposure
to choline hydroxide under reasonably foreseeable circumstances.
In addition to its low toxicity, exposure to choline hydroxide will
be limited. The expected exposure pathway is via the oral and the
dermal routes. Humans are currently exposed to choline on a daily basis
through commonly eaten foods (both naturally occurring and when added
as a nutrient) and through the bodies natural ability to synthesize the
nutrient. It is unlikely that the exposure from choline hydroxide, when
used as an inert ingredient applied preharvest to food commodities,
will significantly increase the natural concentration of choline and
chloride in foods. Choline is also found naturally in the environment.
Taking into consideration all available information on choline
hydroxide, it has been determined that there is a reasonable certainty
that no harm to any population subgroup, including infants and
children, will result from aggregate exposure to this chemical.
Therefore, the establishment of an exemption from tolerance under 40
CFR 180.920 for residues of choline hydroxide when used as an inert
ingredient in pesticide formulations applied to preharvest applications
of pesticides, is safe under FFDCA section 408.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and
Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for choline hydroxide.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.920 for choline hydroxide (CAS Reg. No.
123-41-1) when used as an inert ingredient (in acidic herbicides to act
as a neutralizer]) in pesticide formulations applied to preharvest
applications.
VII. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. 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
[[Page 53581]]
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
