1-Octanamine, N, N-dimethyl-, N-oxide;
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 1-octanamine,
N,N-dimethyl-, N-oxide (CAS Reg. No.
2605–78–9) when used as an inert
ingredient (surfactant) in pesticide
formulations applied to growing crops
and raw agricultural commodities after
harvest, at a concentration of not more
than 15% by weight in pesticide
formulations. The Spring Trading
Company, on behalf of Oxiteno USA,
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 1octanamine, N,N-dimethyl-, N-oxide
when used in accordance with the terms
of the exemption.
DATES: This regulation is effective
September 16, 2020. Objections and
requests for hearings must be received
on or before November 16, 2020 and
must be filed in accordance with the
instructions provided in 40 CFR part
178 (see also Unit I.C. of the

II. Petition for Exemption
In the Federal Register of September
15, 2017 (82 FR 43352) (FRL–9965–43),
EPA issued a document pursuant to
FFDCA section 408, 21 U.S.C. 346a,
announcing the filing of a pesticide
petition (PP IN–11046) by the Spring
Trading Company on behalf of Oxiteno
USA, LLC, 9801 Bay Area Blvd.,
Pasadena, TX 77507. The petition
requested that 40 CFR 180.910 be
amended by establishing an exemption
from the requirement of a tolerance for
residues of 1-octanamine, N,Ndimethyl-, N-oxide (CAS Reg. No. 2605–
78–9) when used as an inert ingredient
(surfactant) in pesticide formulations
applied to growing crops and raw
agricultural commodities after harvest.
That document referenced a summary of
the petition prepared by the Spring
Trading Company on behalf of Oxiteno
USA, LLC, the petitioner, which is
available in the docket, https://
www.regulations.gov. Comments were
received on the notice of filing. EPA’s

16SER1
Federal Register / Vol. 85, No. 180 / Wednesday, September 16, 2020 / Rules and Regulations
response to these comments is
discussed in Unit V.C.
Based upon review of the data
supporting the petition, EPA is
establishing the requested exemption
but with a limitation that the end-use
product not contain 1-octanamine, N,Ndimethyl-, N-oxide in a concentration
that exceeds 15% by weight. The
reasons for this limitation are explained
in the Agency’s risk assessment which
can be found at https://
www.regulations.gov in document ‘‘IN–
11046; 1-Octanamine, N,N-dimethyl-, Noxide—Human Health Risk and
Ecological Effects Assessment of
Request for Food Use Inert Ingredient in
docket ID number EPA–HQ–OPP–2017–
0312.’’
jbell on DSKJLSW7X2PROD with RULES
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
VerDate Sep<11>2014
16:31 Sep 15, 2020
Jkt 250001
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be clearly
demonstrated that the risks from
aggregate exposure to pesticide
chemical residues under reasonably
foreseeable circumstances will pose no
appreciable risks to human health. In
order to determine the risks from
aggregate exposure to pesticide inert
ingredients, the Agency considers the
toxicity of the inert in conjunction with
possible exposure to residues of the
inert ingredient through food, drinking
water, and through other exposures that
occur as a result of pesticide use in
residential settings. If EPA is able to
determine that a finite tolerance is not
necessary to ensure that there is a
reasonable certainty that no harm will
result from aggregate exposure to the
inert ingredient, an exemption from the
requirement of a tolerance may be
established.
Consistent with FFDCA section
408(c)(2)(A), and the factors specified in
FFDCA section 408(c)(2)(B), EPA has
reviewed the available scientific data
and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure for 1-octanamine,
N,N-dimethyl-, N-oxide including
exposure resulting from the exemption
established by this action. EPA’s
assessment of exposures and risks
associated with 1-octanamine, N,Ndimethyl-, N-oxide 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 1-octanamine, N,Ndimethyl-, N-oxide as well as the noobserved-adverse-effect-level (NOAEL)
and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies
can be found at https://
www.regulations.gov in the document
entitled ‘‘IN–11046; 1-Octanamine, N,Ndimethyl-, N-oxide—Human Health
Risk and Ecological Effects Assessment

Ingredient’’ at pages 3–5 in docket ID
number EPA–HQ–OPP–2017–0312.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
The toxicity endpoint selected for use
in risk assessment is taken from the 28day, repeat-dose toxicity study of 1octanamine, N,N-dimethyl-, N-oxide in
which a NOAEL was established at 150
mg/kg/day based on decreases in body
weight, food consumption, mortality,
clinical signs of toxicity, decreased
motor activity, histopathology of the
kidney and spleen, and effects on
hematology and clinical chemistry
parameters seen at 750 mg/kg/day. The
uncertainty factors include 10X for
interspecies extrapolation, 10X for
intraspecies variation, and a 1X for the
FQPA Safety Factor, bringing the
combined uncertainty factor to 100. The
resultant chronic Population Adjusted
Dose (cPAD) is 1.5 mg/kg/day.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to 1-octanamine, N,Ndimethyl-, N-oxide, EPA considered
exposure under the proposed exemption
from the requirement of a tolerance.
EPA assessed dietary exposures from 1-
E:\FR\FM\16SER1.SGM
16SER1
jbell on DSKJLSW7X2PROD with RULES
57752
Federal Register / Vol. 85, No. 180 / Wednesday, September 16, 2020 / Rules and Regulations
octanamine, N,N-dimethyl-, N-oxide in
food as follows:
Because no acute endpoint of concern
was identified, a quantitative acute
dietary exposure assessment is
unnecessary. In conducting the chronic
dietary exposure assessment using the
Dietary Exposure Evaluation Model
(DEEM)—FCIDTM, Version 3.16, EPA
used food consumption information
from the U.S. Department of
Agriculture’s National Health and
Nutrition Examination Survey, What We
Eat in America, (NHANES/WWEIA).
This dietary survey was conducted from
2003 to 2008. Dietary exposure is
estimated using the Agency’s Dietary
Exposure Estimate Model (DEEM). The
Inert Dietary Exposure Evaluation
Model (I–DEEM) is a highly
conservative model with the assumption
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 between the active and
inert ingredient (if any) and that the
concentration of inert ingredient in the
scenarios leading to these highest of
tolerances would be no higher than the
concentration of the active ingredient.
The model assumes 100 percent crop
treated (PCT) for all crops and that every
food eaten by a person each day has
tolerance-level residues. In the case of1octanamine, N,N-dimethyl-, N-oxide, a
15% by weight limitation in formulation
was incorporated into the model.
A complete description of the general
approach taken to assess inert
ingredient risks in the absence of
residue data is contained in the
memorandum entitled ‘‘Alkyl Amines
Polyalkoxylates (Cluster 4): Acute and
Chronic Aggregate (Food and Drinking
Water) Dietary Exposure and Risk
Assessments for the Inerts,’’ (D361707,
S. Piper, 2/25/09) and can be found at
https://www.regulations.gov in docket ID
number EPA–HQ–OPP–2008–0738.
2. Dietary exposure from drinking
water. For the purpose of the screeninglevel dietary risk assessment to support
this request for an exemption from the
requirement of a tolerance for 1octanamine, N,N-dimethyl-, N-oxide, 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
VerDate Sep<11>2014
16:31 Sep 15, 2020
Jkt 250001
(e.g., textiles (clothing and diapers),
carpets, swimming pools, and hard
surface disinfection on walls, floors,
tables).
1-Octanamine, N,N-dimethyl-, Noxide may be used as an inert ingredient
in pesticide products that are registered
for specific uses that may result in
residential exposure, such as pesticides
used in and around the home, and in
non-pesticide products such as
household products, personal care
products and cosmetics. In a
conservative effort to assess residential
exposure, EPA has conducted a
screening-level assessment using highend residential exposure scenarios, such
as pesticides used on lawns/turn, as
antimicrobial cleaning products and in
pet spot on applications.
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 1-octanamine,
N,N-dimethyl-, N-oxide to share a
common mechanism of toxicity with
any other substances, and 1-octanamine,
N,N-dimethyl-, N-oxide does do not
appear to produce a toxic metabolite
produced by other substances. For the
purposes of this tolerance action,
therefore, EPA has assumed that 1octanamine, N,N-dimethyl-, N-oxide
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
1. In general. FFDCA Section
408(b)(2)(c) provides that EPA shall
apply an additional tenfold (10X)
margin of safety for infants and children
in the case of threshold effects to
account for prenatal and postnatal
toxicity and the completeness of the
database on toxicity and exposure
unless EPA determines based on reliable
data that a different margin of safety
will be safe for infants and children.
This additional margin of safety is
commonly referred to as the FQPA
safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional safety factor when reliable
PO 00000
Frm 00088
Fmt 4700
Sfmt 4700
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
No evidence of increased quantitative or
qualitative susceptibility was seen in
developmental toxicity studies in rats
and rabbits with 1-octanamine, N,Ndimethyl-, N-oxide. No adverse effects
on reproductive parameters were
observed in a 2-generation rat
reproductive study.
3. Conclusion. EPA has determined
that reliable data show the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1X. That decision is
based on the following findings:
i. The database for 1-octanamine, N,Ndimethyl-, N-oxide is considered
adequate for FQPA assessment.
ii. A combined repeated dose toxicity
study with a reproduction/
developmental toxicity screening test
showed no effect on reproductive
parameters of fertility in the absence of
maternal toxicity.
iii. Although no neurotoxicity studies
are available, no clinical signs of
neurotoxicity were observed. Therefore,
there is no need for a developmental
neurotoxicity study or additional UFs to
account for neurotoxicity.
iv. Immunotoxicity studies were not
available. However, there were no testitem related signs of immunotoxicity
noted in the repeat-dose study.
v. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100% CT and
incorporated a limitation of 15% by
weight in pesticide formulation. EPA
made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to 1-octanamine, N,N-dimethyl-, Noxide in drinking water. EPA used
similarly conservative assumptions to
assess post-application exposure of
children. These assessments will not
underestimate the exposure and risks
posed by 1-octanamine, N,N-dimethyl-,
N-oxide.
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
E:\FR\FM\16SER1.SGM
16SER1
jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 85, No. 180 / Wednesday, September 16, 2020 / Rules and Regulations
PODs to ensure that an adequate MOE
exists.
1. Acute risk. Using the exposure
assumptions discussed in this unit for
acute exposure, no adverse effects were
attributed to a single exposure of the
acute dietary exposure from food and
water to -octanamine, N,N-dimethyl-, Noxide. Therefore, 1-octanamine, N,Ndimethyl-, N-oxide is not expected to
pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to 1-octanamine,
N,N-dimethyl-, N-oxide, from food and
water will utilize 14.1% of the cPAD for
all infants less than 1 year old, the
population group receiving the greatest
exposure. Based on the explanation in
Unit III.C.3., regarding residential use
patterns, chronic residential exposure to
residues of 1-octanamine, N,Ndimethyl-, N-oxide is not expected.
3. Short-term risk. Short-term
aggregate exposure considers short-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level). 1Octanamine, N,N-dimethyl-, N-oxide is
currently registered for uses that could
result in short-term residential
exposure, and the Agency has
determined that it is appropriate to
aggregate chronic exposure through food
and water with short-term residential
exposures to 1-octanamine, N,Ndimethyl-, N-oxide.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 1978 for adults and 589 for
children. Because EPA’s level of
concern for 1-octanamine, N,Ndimethyl-, N-oxide is an MOE of 100 or
below, these MOEs are not of concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level
exposure. Because there is no
intermediate-term residential exposure
and chronic dietary exposure has
already been assessed under the
appropriately protective cPAD (which is
at least as protective as the POD used to
assess intermediate-term risk), no
further assessment of intermediate-term
risk is necessary, and EPA relies on the
chronic dietary risk assessment for
evaluating intermediate-term risk for 1octanamine, N,N-dimethyl-, N-oxide.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in a rodent
VerDate Sep<11>2014
16:31 Sep 15, 2020
Jkt 250001
carcinogenicity study, 1-octanamine,
N,N-dimethyl-, N-oxide is not expected
to pose a cancer risk to humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to 1octanamine, N,N-dimethyl-, N-oxide
residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is not establishing a numerical
tolerance for residues of 1-octanamine,
N,N-dimethyl-, N-oxide in or on any
food commodities. EPA is establishing
limitations on the amount of 1octanamine, N,N-dimethyl-, N-oxide
that may be used in pesticide
formulations applied pre- and postharvest. These limitations 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
15% by weight of 1-octanamine, N,Ndimethyl-, N-oxide in the final pesticide
formulation.
B. Response to Comments
Two comments were received
concerning the safety and impact of
pesticides on food and human health.
Although the Agency recognizes that
some individuals believe that no residue
of pesticides should be allowed in or on
food, the existing legal framework
provided by section 408 of the Federal
Food, Drug and Cosmetic Act (FFDCA)
authorizes the establishment of
pesticide tolerances or exemptions
where the Agency determines that
tolerance or exemption meets the safety
standard imposed by the statute. EPA
has sufficient data to support a safety
determination for the exemption from
the requirement of a tolerance for 1octanamine, N,N-dimethyl-, N-oxide.
The commenters have provided no
additional information supporting a
determination that the exemption is not
safe.
C. Revisions to Petitioned-For
Tolerances
Based upon an evaluation of the data
included in the petition, EPA is
establishing an exemption from the
requirement of a tolerance for residues
of 1-octanamine, N,N-dimethyl-, Noxide when used in pesticide
formulations as an inert ingredient
PO 00000
Frm 00089
Fmt 4700
Sfmt 4700
57753
(surfactant), not to exceed 15% by
weight of the formulation, instead of the
unlimited use requested. Because
unlimited use of 1-Octanamine, N,Ndimethyl-, N-oxide resulted in aggregate
risks of concern, EPA is establishing a
15% limitation in formulation to
support the safety finding of these
tolerance exemptions. The concern for
unlimited use of theses inert ingredients
is documented on page 4 of the
Agency’s risk assessment documents
‘‘IN–11046; 1-Octanamine, N,Ndimethyl-, N-oxide—Human Health
Risk and Ecological Effects Assessment
of Request for Food Use Inert
Ingredient’’ which can be found at
https://www.regulations.gov in docket ID
number EPA–HQ–OPP–2017–0312.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.910 for 1-octanamine,
N,N-dimethyl-, N-oxide when used as
an inert ingredient (surfactant) limited
to 15% by weight in pesticide
formulations applied to growing crops
or raw agricultural commodities after
harvest.
VII. Statutory and Executive Order
Reviews
This action establishes an exemption
from the requirement of a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types

Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or Tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or Tribal Governments, on the
relationship between the National
Government and the States or Tribal
Governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
Tribes. Thus, the Agency has
determined that Executive Order 13132,
entitled ‘‘Federalism’’ (64 FR 43255,
August 10, 1999) and Executive Order
13175, entitled ‘‘Consultation and
Coordination with Indian Tribal
Governments’’ (65 FR 67249, November
9, 2000) do not apply to this action. In
addition, this action does not impose
any enforceable duty or contain any
unfunded mandate as described under
Title II of the Unfunded Mandates
Reform Act (UMRA) (2 U.S.C. 1501 et
seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
VIII. Congressional Review Act (CRA)
Pursuant to the CRA (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

1-Octanamine, N, N-dimethyl-, N-oxide; 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 1-octanamine, N,N-dimethyl-, N-oxide
(CAS Reg. No. 2605-78-9) when used as an inert ingredient (surfactant)
in pesticide formulations applied to growing crops and raw agricultural
commodities after harvest, at a concentration of not more than 15% by
weight in pesticide formulations. The Spring Trading Company, on behalf
of Oxiteno USA, 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 1-octanamine, N,N-dimethyl-, N-oxide when used in
accordance with the terms of the exemption.
DATES: This regulation is effective September 16, 2020. Objections and
requests for hearings must be received on or before November 16, 2020
and must be filed in accordance with the instructions provided in 40

II. Petition for Exemption
In the Federal Register of September 15, 2017 (82 FR 43352) (FRL-
9965-43), EPA issued a document pursuant to FFDCA section 408, 21
U.S.C. 346a, announcing the filing of a pesticide petition (PP IN-
11046) by the Spring Trading Company on behalf of Oxiteno USA, LLC,
9801 Bay Area Blvd., Pasadena, TX 77507. The petition requested that 40
CFR 180.910 be amended by establishing an exemption from the
requirement of a tolerance for residues of 1-octanamine, N,N-dimethyl-,
N-oxide (CAS Reg. No. 2605-78-9) when used as an inert ingredient
(surfactant) in pesticide formulations applied to growing crops and raw
agricultural commodities after harvest. That document referenced a
summary of the petition prepared by the Spring Trading Company on
behalf of Oxiteno USA, LLC, the petitioner, which is available in the
docket, https://www.regulations.gov. Comments were received on the
notice of filing. EPA's
[[Page 57751]]
response to these comments is discussed in Unit V.C.
Based upon review of the data supporting the petition, EPA is
establishing the requested exemption but with a limitation that the
end-use product not contain 1-octanamine, N,N- dimethyl-, N-oxide in a
concentration that exceeds 15% by weight. The reasons for this
limitation are explained in the Agency's risk assessment which can be
found at https://www.regulations.gov in document ``IN-11046; 1-
Octanamine, N,N-dimethyl-, N-oxide--Human Health Risk and Ecological
Effects Assessment of Request for Food Use Inert Ingredient in docket
ID number EPA-HQ-OPP-2017-0312.''
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 FFDCA section 408(c)(2)(A), and the factors
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for 1-octanamine, N,N-dimethyl-, N-
oxide including exposure resulting from the exemption established by
this action. EPA's assessment of exposures and risks associated with 1-
octanamine, N,N-dimethyl-, N-oxide 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 1-octanamine, N,N-dimethyl-, N-oxide as well
as the no-observed-adverse-effect-level (NOAEL) and the lowest-
observed-adverse-effect-level (LOAEL) from the toxicity studies can be
found at https://www.regulations.gov in the document entitled ``IN-
11046; 1-Octanamine, N,N-dimethyl-, N-oxide--Human Health Risk and
Ecological Effects Assessment of Request for Food Use Inert
Ingredient'' at pages 3-5 in docket ID number EPA-HQ-OPP-2017-0312.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
The toxicity endpoint selected for use in risk assessment is taken
from the 28-day, repeat-dose toxicity study of 1-octanamine, N,N-
dimethyl-, N-oxide in which a NOAEL was established at 150 mg/kg/day
based on decreases in body weight, food consumption, mortality,
clinical signs of toxicity, decreased motor activity, histopathology of
the kidney and spleen, and effects on hematology and clinical chemistry
parameters seen at 750 mg/kg/day. The uncertainty factors include 10X
for interspecies extrapolation, 10X for intraspecies variation, and a
1X for the FQPA Safety Factor, bringing the combined uncertainty factor
to 100. The resultant chronic Population Adjusted Dose (cPAD) is 1.5
mg/kg/day.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to 1-octanamine, N,N-dimethyl-, N-oxide, EPA considered
exposure under the proposed exemption from the requirement of a
tolerance. EPA assessed dietary exposures from 1-
[[Page 57752]]
octanamine, N,N-dimethyl-, N-oxide in food as follows:
Because no acute endpoint of concern was identified, a quantitative
acute dietary exposure assessment is unnecessary. In conducting the
chronic dietary exposure assessment using the Dietary Exposure
Evaluation Model (DEEM)--FCID\TM\, Version 3.16, EPA used food
consumption information from the U.S. Department of Agriculture's
National Health and Nutrition Examination Survey, What We Eat in
America, (NHANES/WWEIA). This dietary survey was conducted from 2003 to
2008. Dietary exposure is estimated using the Agency's Dietary Exposure
Estimate Model (DEEM). The Inert Dietary Exposure Evaluation Model (I-
DEEM) is a highly conservative model with the assumption 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 between the active and
inert ingredient (if any) and that the concentration of inert
ingredient in the scenarios leading to these highest of tolerances
would be no higher than the concentration of the active ingredient. The
model assumes 100 percent crop treated (PCT) for all crops and that
every food eaten by a person each day has tolerance-level residues. In
the case of1-octanamine, N,N-dimethyl-, N-oxide, a 15% by weight
limitation in formulation was incorporated into the model.
A complete description of the general approach taken to assess
inert ingredient risks in the absence of residue data is contained in
the memorandum entitled ``Alkyl Amines Polyalkoxylates (Cluster 4):
Acute and Chronic Aggregate (Food and Drinking Water) Dietary Exposure
and Risk Assessments for the Inerts,'' (D361707, S. Piper, 2/25/09) and
can be found at https://www.regulations.gov in docket ID number EPA-HQ-
OPP-2008-0738.
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 1-octanamine, N,N-
dimethyl-, N-oxide, a conservative drinking water concentration value
of 100 ppb based on screening-level modeling was used to assess the
contribution to drinking water for the chronic dietary risk assessments
for parent compound. These values were directly entered into the
dietary exposure model.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., textiles (clothing and diapers), carpets, swimming
pools, and hard surface disinfection on walls, floors, tables).
1-Octanamine, N,N-dimethyl-, N-oxide may be used as an inert
ingredient in pesticide products that are registered for specific uses
that may result in residential exposure, such as pesticides used in and
around the home, and in non-pesticide products such as household
products, personal care products and cosmetics. In a conservative
effort to assess residential exposure, EPA has conducted a screening-
level assessment using high-end residential exposure scenarios, such as
pesticides used on lawns/turn, as antimicrobial cleaning products and
in pet spot on applications.
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 1-octanamine, N,N-dimethyl-, N-oxide to share a
common mechanism of toxicity with any other substances, and 1-
octanamine, N,N-dimethyl-, N-oxide does do not appear to produce a
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that 1-octanamine, N,N-
dimethyl-, N-oxide 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
1. In general. FFDCA Section 408(b)(2)(c) provides that EPA shall
apply an additional tenfold (10X) margin of safety for infants and
children in the case of threshold effects to account for prenatal and
postnatal toxicity and the completeness of the database on toxicity and
exposure unless EPA determines based on reliable data that a different
margin of safety will be safe for infants and children. This additional
margin of safety is commonly referred to as the FQPA safety factor
(SF). In applying this provision, EPA either retains the default value
of 10X, or uses a different additional safety factor when reliable data
available to EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. No evidence of increased
quantitative or qualitative susceptibility was seen in developmental
toxicity studies in rats and rabbits with 1-octanamine, N,N-dimethyl-,
N-oxide. No adverse effects on reproductive parameters were observed in
a 2-generation rat reproductive study.
3. Conclusion. EPA has determined that reliable data show the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1X. That decision is based on the following
findings:
i. The database for 1-octanamine, N,N-dimethyl-, N-oxide is
considered adequate for FQPA assessment.
ii. A combined repeated dose toxicity study with a reproduction/
developmental toxicity screening test showed no effect on reproductive
parameters of fertility in the absence of maternal toxicity.
iii. Although no neurotoxicity studies are available, no clinical
signs of neurotoxicity were observed. Therefore, there is no need for a
developmental neurotoxicity study or additional UFs to account for
neurotoxicity.
iv. Immunotoxicity studies were not available. However, there were
no test-item related signs of immunotoxicity noted in the repeat-dose
study.
v. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100% CT and incorporated a limitation of 15% by weight in pesticide
formulation. EPA made conservative (protective) assumptions in the
ground and surface water modeling used to assess exposure to 1-
octanamine, N,N-dimethyl-, N-oxide in drinking water. EPA used
similarly conservative assumptions to assess post-application exposure
of children. These assessments will not underestimate the exposure and
risks posed by 1-octanamine, N,N-dimethyl-, N-oxide.
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
[[Page 57753]]
PODs to ensure that an adequate MOE exists.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, no adverse effects were attributed to a single
exposure of the acute dietary exposure from food and water to -
octanamine, N,N-dimethyl-, N-oxide. Therefore, 1-octanamine, N,N-
dimethyl-, N-oxide is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
1-octanamine, N,N-dimethyl-, N-oxide, from food and water will utilize
14.1% of the cPAD for all infants less than 1 year old, the population
group receiving the greatest exposure. Based on the explanation in Unit
III.C.3., regarding residential use patterns, chronic residential
exposure to residues of 1-octanamine, N,N-dimethyl-, N-oxide is not
expected.
3. Short-term risk. Short-term aggregate exposure considers short-
term residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). 1-Octanamine, N,N-
dimethyl-, N-oxide is currently registered for uses that could result
in short-term residential exposure, and the Agency has determined that
it is appropriate to aggregate chronic exposure through food and water
with short-term residential exposures to 1-octanamine, N,N-dimethyl-,
N-oxide.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 1978 for adults
and 589 for children. Because EPA's level of concern for 1-octanamine,
N,N-dimethyl-, N-oxide is an MOE of 100 or below, these MOEs are not of
concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level exposure. Because there is no intermediate-term residential
exposure and chronic dietary exposure has already been assessed under
the appropriately protective cPAD (which is at least as protective as
the POD used to assess intermediate-term risk), no further assessment
of intermediate-term risk is necessary, and EPA relies on the chronic
dietary risk assessment for evaluating intermediate-term risk for 1-
octanamine, N,N-dimethyl-, N-oxide.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in a rodent carcinogenicity study, 1-
octanamine, N,N-dimethyl-, N-oxide is not expected to pose a cancer
risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to 1-octanamine, N,N-dimethyl-, N-oxide residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is not establishing a numerical tolerance for residues of 1-
octanamine, N,N-dimethyl-, N-oxide in or on any food commodities. EPA
is establishing limitations on the amount of 1-octanamine, N,N-
dimethyl-, N-oxide that may be used in pesticide formulations applied
pre- and post- harvest. These limitations 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
15% by weight of 1-octanamine, N,N-dimethyl-, N-oxide in the final
pesticide formulation.
B. Response to Comments
Two comments were received concerning the safety and impact of
pesticides on food and human health. Although the Agency recognizes
that some individuals believe that no residue of pesticides should be
allowed in or on food, the existing legal framework provided by section
408 of the Federal Food, Drug and Cosmetic Act (FFDCA) authorizes the
establishment of pesticide tolerances or exemptions where the Agency
determines that tolerance or exemption meets the safety standard
imposed by the statute. EPA has sufficient data to support a safety
determination for the exemption from the requirement of a tolerance for
1-octanamine, N,N-dimethyl-, N-oxide. The commenters have provided no
additional information supporting a determination that the exemption is
not safe.
C. Revisions to Petitioned-For Tolerances
Based upon an evaluation of the data included in the petition, EPA
is establishing an exemption from the requirement of a tolerance for
residues of 1-octanamine, N,N-dimethyl-, N-oxide when used in pesticide
formulations as an inert ingredient (surfactant), not to exceed 15% by
weight of the formulation, instead of the unlimited use requested.
Because unlimited use of 1-Octanamine, N,N-dimethyl-, N-oxide resulted
in aggregate risks of concern, EPA is establishing a 15% limitation in
formulation to support the safety finding of these tolerance
exemptions. The concern for unlimited use of theses inert ingredients
is documented on page 4 of the Agency's risk assessment documents ``IN-
11046; 1-Octanamine, N,N-dimethyl-, N-oxide--Human Health Risk and
Ecological Effects Assessment of Request for Food Use Inert
Ingredient'' which can be found at https://www.regulations.gov in docket
ID number EPA-HQ-OPP-2017-0312.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.910 for 1-octanamine, N,N-dimethyl-, N-
oxide when used as an inert ingredient (surfactant) limited to 15% by
weight in pesticide formulations applied to growing crops or raw
agricultural commodities after harvest.
VII. Statutory and Executive Order Reviews
This action establishes an exemption from the requirement of a
tolerance under FFDCA section 408(d) in response to a petition
submitted to the Agency. The Office of Management and Budget (OMB) has
exempted these types of actions from review under Executive Order
12866, entitled ``Regulatory Planning and Review'' (58 FR 51735,
October 4, 1993). Because this action has been exempted from review
under Executive Order 12866, this action is not subject to Executive
Order 13211, entitled ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR
28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of
Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), nor is it considered a regulatory action under
Executive Order 13771, entitled ``Reducing Regulations and Controlling
Regulatory Costs'' (82 FR 9339, February 3, 2017). This action does not
contain any information collections subject to OMB approval under the
Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it
require any special considerations under Executive Order 12898,
entitled ``Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations'' (59 FR 7629, February 16,
1994).
[[Page 57754]]
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or Tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
Tribal Governments, on the relationship between the National Government
and the States or Tribal Governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian Tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VIII. Congressional Review Act (CRA)
Pursuant to the CRA (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).
