I. General Information
This regulation establishes an
exemption from the requirement of a
tolerance for residues of n-octyl alcohol
(CAS Reg. No. 111–87–5); and n-decyl
alcohol (CAS Reg. No. 112–30–1) when
used as an inert ingredient (solvent or
co-solvent) in pesticide formulations
applied to growing crops or to raw
agricultural commodities after harvest
under EPA regulations. Technology
Sciences Group Inc., on behalf of
AMVAC, Chemical Corporation,
submitted a petition to EPA under the
Federal Food, Drug, and Cosmetic Act
(FFDCA), requesting establishment of an
exemption from the requirement of a
tolerance. This regulation eliminates the
need to establish a maximum
permissible level for residues of n-octyl
alcohol and n-decyl alcohol.

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
VerDate Mar<15>2010
14:40 Feb 03, 2011
Jkt 223001
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 n-octyl alcohol
and n-decyl alcohol including exposure
resulting from the exemption
established by this action. EPA’s
assessment of exposures and risks
associated with n-octyl alcohol and ndecyl alcohol follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered their
validity, completeness, and reliability as
well as the relationship of the results of
the studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children. Specific
information on the studies received and
the nature of the adverse effects caused
by n-octyl alcohol and n-decyl alcohol
as well as the no-observed-adverseeffect-level (NOAEL) and the lowestobserved-adverse-effect-level (LOAEL)
from the toxicity studies are discussed
in this unit.
The following provides a brief
summary for the risk assessment and
conclusions for the Agency’s review for
the aliphatic alcohols, which include noctyl alcohol and n-decyl alcohol. The
Agency’s full decision document for this
action is available in the Agency’s
electronic docket (regulations.gov)
under the docket number EPA–HQ–
OPP–2010–0181. Details regarding the
Agency’s findings with regards to
human health and environmental fate

chemical properties, toxicological
effects, and exposure profile of n-octyl
and n-decyl alcohols can be found on
the 2006 Agency’s reassessment
decision document for tolerance
exemption at https://www.epa.gov/
opprd001/inerts/octyldecyl.pdf.
Briefly, the available acute toxicity
studies indicate the aliphatic alcohols
are of low acute toxicity. Acute oral
toxicity for n-octyl alcohol was 4,135
milligrams/kilogram (mg/kg) and for ndecyl alcohol was 9,800 mg/kg. Acute
inhalation studies with the rat resulted
in LC50 estimates above the limit
concentration of 2 milligrams per Liter
(mg/L). Eye irritation studies with
undiluted test compound resulted in
severe and sometimes non-reversible
eye damage. Dermal irritation studies
revealed slight to moderate irritation in
rabbits. The aliphatic alcohols generally
did not produce sensitization in guinea
pigs.
A 90-day dermal toxicity study in rats
with fatty alcohol blend (56.7%
decanol, 42.7% octanol) at dose levels
of 0, 100, 300, or 1,000 mg/kg resulted
in severe irritation at the application
site. Severe irritation including fissuring
of the skin occurred in 40% of the
animals at 100 mg/kg/day and 80% of
the animals at the limit dose. Slight
changes in hematology, clinical
chemistry, and organ weights were
noted at the limit dose of 1,000 mg/kg/
day. The systemic toxicity NOAEL in
the 90-day dermal study was 300 mg/kg/
day based on changes in clinical
chemistry and hematological
parameters, and organ weight changes
seen at the LOAEL of 1,000 mg/kg/day.
No systemic or developmental toxicity
was observed in the developmental
toxicity studies in rats via the inhalation
with n-decyl alcohol at the maximum
attainable vapor concentration (100 mg/
cubic meter (m3)) approximately
equivalent to 30 mg/kg/day. Similarly,
no maternal or developmental toxicity
was seen in an oral (gavage)
developmental toxicity study in rats
with fatty alcohol blend at doses up to
1,000 mg/kg/day. Aliphatic alcohols
gave a negative response for
mutagenicity in the available studies.
No long term studies or carcinogenicity
studies are available in the database via
oral routes of exposure. However, as a
class, the straight chain aliphatic
alcohols are not considered
carcinogenic. In addition, the Agency
used a qualitative structure activity
relationship (QSAR) database,
DEREK11, to determine if there were
structural alerts suggestive of
carcinogenicity. No structural alerts for
carcinogenicity were identified.

B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to n-octyl and n-decyl alcohol,
EPA considered exposure under the
proposed exemption from the
requirement of a tolerance. EPA
assessed dietary exposures from n-octy
and n-decyl alcohol in food as follows:
i. Acute exposure. No adverse effects
attributable to a single exposure of noctyl alcohol and n-dectyl alcohol were
seen in the available toxicity studies.
Therefore, an acute dietary risk
assessment for n-octyl and n-decyl
alcohol was not conducted.
ii. Chronic exposure. In conducting
the chronic dietary exposure
assessment, EPA used food
consumption information from the U.S.
Department of Agriculture (USDA)
1994–1996 and 1998 Nationwide
Continuing Surveys of Food Intake by
Individuals (CSFII). As to residue levels
in food, no residue data were submitted
for n-octyl and n-decyl alcohol. In the
absence of specific residue data, EPA
has developed an approach which uses
surrogate information to derive upper
bound exposure estimates for the
subject inert ingredients. Upper bound
exposure estimates are based on the
highest tolerance for a given commodity
from a list of high-use insecticides,
herbicides, and fungicides. A complete
description of the general approach
taken to assess inert ingredient risks in
the absence of residue data is contained
in the memorandum entitled ‘‘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.
In the dietary exposure assessment,
the Agency assumed that the residue
level of the inert ingredient would be no
higher than the highest tolerance for a
given commodity. Implicit in this
assumption is that there would be
similar rates of degradation (if any)
between the active and inert ingredient
and that the concentration of inert
ingredient in the scenarios leading to
these highest of tolerances would be no
higher than the concentration of the
active ingredient.
VerDate Mar<15>2010
14:40 Feb 03, 2011
Jkt 223001
The Agency believes the assumptions
used to estimate dietary exposures lead
to an extremely conservative assessment
of dietary risk due to a series of
compounded conservatisms. First,
assuming that the level of residue for an
inert ingredient is equal to the level of
residue for the active ingredient will
overstate exposure. The concentration of
active ingredient in agricultural
products is generally at least 50 percent
of the product and often can be much
higher. Further, pesticide products
rarely have a single inert ingredient;
rather, there is generally a combination
of different inert ingredients used which
additionally reduces the concentration
of any single inert ingredient in the
pesticide product in relation to that of
the active ingredient.
Second, the conservatism of this
methodology is compounded by EPA’s
decision to assume that, for each
commodity, the active ingredient which
will serve as a guide to the potential
level of inert ingredient residues is the
active ingredient with the highest
tolerance level. This assumption
overstates residue values because it
would be highly unlikely, given the
high number of inert ingredients, that a
single inert ingredient or class of
ingredients would be present at the
level of the active ingredient in the
highest tolerance for every commodity.
Finally, a third compounding
conservatism is EPA’s assumption that
all foods contain the inert ingredient at
the highest tolerance level. In other
words, EPA assumed 100 percent of all
foods are treated with the inert
ingredient at the rate and manner
necessary to produce the highest residue
legally possible for an active ingredient.
In summary, EPA chose a very
conservative method for estimating
what level of inert residue could be on
food, and then used this methodology to
choose the highest possible residue that
could be found on food and assumed
that all food contained this residue. No
consideration was given to potential
degradation between harvest and
consumption even though monitoring
data shows that tolerance level residues
are typically 1 to 2 orders of magnitude
higher than actual residues in food
when distributed in commerce.
Accordingly, although sufficient
information to quantify actual residue
levels in food is not available, the
compounding of these conservative
assumptions will lead to a significant
exaggeration of actual exposures. EPA
does not believe that this approach
underestimates exposure in the absence
of residue data.
iii. Cancer. The Agency used a
qualitative structure activity
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
relationship (QSAR) database,
DEREK11, to determine if there were
structural alerts suggestive of
carcinogenicity. No structural alerts for
carcinogenicity were identified.
Therefore, a quantitative dietary
exposure assessment was not conducted
for the purpose of evaluating cancer
risk.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue and or PCT
information in the dietary assessment
for n-octyl and n-decyl alcohol.
Tolerance level residues and/or 100 PCT
were assumed for all food commodities.
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, a
conservative drinking water
concentration value of 100 parts per
billion (ppb) based on screening level
modeling was used to assess the
contribution to drinking water for the
chronic dietary risk assessments for
parent compound. These values were
directly entered into the dietary
exposure model.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., textiles (clothing and diapers),
carpets, swimming pools, and hard
surface disinfection on walls, floors,
tables). Due to the low hazard profile
and lack of endpoint selection for the
dermal route of exposure, no post
application dermal risk was assessed.
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 n-octyl and ndecyl alcohols to share a common
mechanism of toxicity with any other
substances, and does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that n-octyl and n-decyl
alcohol do not have a common
mechanism of toxicity with other
substances. For information regarding
EPA’s efforts to determine which
chemicals have a common mechanism
of toxicity and to evaluate the
cumulative effects of such chemicals,
see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.

C. Safety Factor for Infants and Children
Section 408(b)(2)(C) of FFDCA
provides that EPA shall apply an
additional tenfold (10X) margin of safety
for infants and children in the case of
threshold effects to account for prenatal
and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines,
based on reliable data, that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act Safety
Factor (FQPA 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. EPA has determind
that reliable data show the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1X. The decision is
based on the following findings:
1. The database on n-octyl alcohol
and n-decyl alcohol is considered
adequate for FQPA assessment. The
database includes two developmental
toxicity studies in rats via oral route of
exposure, one developmental toxicity
study in rats via inhalation routes and
one Organization of Economic
Development (OECD) 422 study
(reproductive and developmental
screening study) in rats. In addition,
there are a 90-day dermal toxicity study
in rats and several mutagenicity studies.
2. There is no evidence of increased
susceptibility of infants and children
from exposure to low chain aliphatic
alcohols. In developmental toxicity
studies in rats via the oral route, no
developmental toxicity was seen at
doses 1,000 mg/kg/day and above. No
developmental or systemic toxicity was
seen in the developmental toxicity
study in rats via the inhalation route of
exposure. No evidence of fetal or
systemic toxicity was seen at doses up
to 2,000 mg/kg/day in the OECD 422
study in rats.
3. There is no indication in the
database that n-octyl and n-decyl
alcohols are neurotoxic chemicals
except when administered in high bolus
doses. Therefore, there is no need for a
developmental neurotoxicity study.
There is no indication of
immunotoxicity in the available
database; therefore, an immunotoxicity
study is not required.
4. There are no long-term studies in
the database but there are no concerns
for the lack of such data because the
available studies indicate that no
systemic toxicity was seen at the limit
dose or above except in one
VerDate Mar<15>2010
14:40 Feb 03, 2011
Jkt 223001
developmental gavage study in rats in
which the salivation was seen at the
high dose of 1,000 mg/kg/day. This
effect is considered to be due to bolus
gavage dosing. This study and endpoint
was used for the chronic reference dose
(RfD), therefore, providing conservative
estimates.
5. There are no residual uncertainties
identified in the exposure databases.
The food and drinking water assessment
is not likely to underestimate exposure
to any subpopulation, including those
comprised of infants and children. The
dietary exposure assessments are
considered to be highly conservative as
they are based on the use of the highest
tolerance level from the surrogate
pesticides for every food and 100% crop
treated is assumed for all crops. EPA
also made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to n-octyl alcohol and n-decyl alcohol in
drinking water. These assessments will
not underestimate the exposure and
risks posed by both alcohols. Based on
the above considerations; EPA has
reduced the FQPA factor to 1X.
D. 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 population
adjusted dose (aPAD) and chronic
population adjusted dose (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
point of departures (PODs) to ensure
that an adequate margin of exposure
(MOE) exists.
1. Acute aggregate (food and drinking
water) risk. No adverse effect resulting
from a single oral exposure was
identified and no acute dietary endpoint
was selected. Therefore, n-octyl alcohol
and n-decyl alcohol are not expected to
pose an acute risk.
2. Chronic aggregate (food and
drinking water) risk. A chronic aggregate
risk assessment takes into account
exposure estimates from chronic dietary
consumption of food and drinking
water. Using the exposure assumptions
discussed in this unit for chronic
exposure, the chronic dietary exposure
from food and water to n-octyl alcohol
and n-decyl alcohol is 5.1% of the cPAD
for the U.S. population and 16.6% of the
cPAD for children 1–2 years old, the
most highly exposed population
subgroup. The chronic dietary exposure
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
6345
estimates for food and drinking water
are below the Agency’s level of concern
(<100% cPAD) for the U.S. population
and all population subgroups.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water
(considered to be a background
exposure level). Short- term quantitative
aggregate risk assessment was not
conducted because there is low hazard
via the oral, dermal and inhalation
routes of exposure. The endpoint of
concern for the chronic RfD was based
on the conservative NOAEL of 375 mg/
kg/day. This NOAEL was based on
salivation seen at the LOAEL of 1,000
mg/kg/day in a developmental toxicity
study in rats. The dietary exposure from
food and water is estimated to be 5.1%
of the cPAD. The short-term residential
exposure is not expected to be 95% of
the cPAD because dermal and
inhalation exposures are not likely to be
significant since the alcohols will be
readily volatized and dissipated in the
environment. Therefore, aggregate shortterm exposure does not pose a risk
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).
Intermediate-term quantitative aggregate
risk assessment was not conducted
because there is low hazard via the oral,
dermal and inhalation routes of
exposure. The endpoint of concern for
the chronic RfD was based on the
conservative NOAEL of 375 mg/kg/day.
This NOAEL was based on salivation
seen at the LOAEL of 1,000 mg/kg/day
in a developmental toxicity study in
rats. The dietary exposure from food
and water is estimated to be 5.1% of the
cPAD. The intermediate-term residential
exposure is not expected to be 95% of
the cPAD because dermal and
inhalation exposure are not likely to be
significant since the alcohols will be
readily volatized and dissipated in the
environment. Therefore quantitative
short-term residential exposure
assessment was not conducted.
5. Aggregate cancer risk for U.S.
population. The Agency has not
identified any concerns for
carcinogenicity relating to n-octyl
alcohol and n-decyl alcohol.
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 n-octyl
alcohol and n-decyl alcohol 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 residue of n-octyl alcohol
and n-decyl alcohol in or any food
commodities.
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 n-octyl and n-decyl alcohol.
VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.910 for of n-octyl
alcohol (CAS Reg. No. 111–87–5); and
n-decyl alcohol (CAS Reg. No. 112–30–
1) when used as an inert ingredient
(solvent or co-solvent) in pesticide
formulations applied to growing crops
or to raw agricultural commodities after
harvest under 40 CFR 180.910.
VII. Statutory and Executive Order
Reviews
This final rule establishes an
exemption from the requirement of 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 exemptions 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
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) (Pub. L. 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).

[[Page 6343]]
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 n-octyl alcohol and n-decyl
alcohol including exposure resulting from the exemption established by
this action. EPA's assessment of exposures and risks associated with n-
octyl alcohol and n-decyl alcohol follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. Specific information on the studies received and the nature
of the adverse effects caused by n-octyl alcohol and n-decyl alcohol as
well as the no-observed-adverse-effect-level (NOAEL) and the lowest-
observed-adverse-effect-level (LOAEL) from the toxicity studies are
discussed in this unit.
The following provides a brief summary for the risk assessment and
conclusions for the Agency's review for the aliphatic alcohols, which
include n-octyl alcohol and n-decyl alcohol. The Agency's full decision
document for this action is available in the Agency's electronic docket
(regulations.gov) under the docket number EPA-HQ-OPP-2010-0181. Details
regarding the Agency's findings with regards to human health and
environmental fate and effects, are found in: ``Aliphatic Alcohols:
Human Health Chapter of the Reregistration Eligibility Decision (RED)
Document Reregistration Case Number 4004 (June 30, 2006). DP Barcode:
325712; PC Codes: 079029, 079038, 079059'' (June 30, 2006), and
``Ecological Risk Assessment Aliphatic Alcohols Considered in
Registration Case 4004''. These documents are available on the Agency's
Web site in the EPA Docket at: https://www.regulations.gov (Docket ID
EPA-HQ-2007-0134). Additional information on the use, physical/chemical
properties, toxicological effects, and exposure profile of n-octyl and
n-decyl alcohols can be found on the 2006 Agency's reassessment
decision document for tolerance exemption at https://www.epa.gov/opprd001/inerts/octyldecyl.pdf.
Briefly, the available acute toxicity studies indicate the
aliphatic alcohols are of low acute toxicity. Acute oral toxicity for
n-octyl alcohol was 4,135 milligrams/kilogram (mg/kg) and for n-decyl
alcohol was 9,800 mg/kg. Acute inhalation studies with the rat resulted
in LC50 estimates above the limit concentration of 2
milligrams per Liter (mg/L). Eye irritation studies with undiluted test
compound resulted in severe and sometimes non-reversible eye damage.
Dermal irritation studies revealed slight to moderate irritation in
rabbits. The aliphatic alcohols generally did not produce sensitization
in guinea pigs.
A 90-day dermal toxicity study in rats with fatty alcohol blend
(56.7% decanol, 42.7% octanol) at dose levels of 0, 100, 300, or 1,000
mg/kg resulted in severe irritation at the application site. Severe
irritation including fissuring of the skin occurred in 40% of the
animals at 100 mg/kg/day and 80% of the animals at the limit dose.
Slight changes in hematology, clinical chemistry, and organ weights
were noted at the limit dose of 1,000 mg/kg/day. The systemic toxicity
NOAEL in the 90-day dermal study was 300 mg/kg/day based on changes in
clinical chemistry and hematological parameters, and organ weight
changes seen at the LOAEL of 1,000 mg/kg/day. No systemic or
developmental toxicity was observed in the developmental toxicity
studies in rats via the inhalation with n-decyl alcohol at the maximum
attainable vapor concentration (100 mg/cubic meter (m\3\))
approximately equivalent to 30 mg/kg/day. Similarly, no maternal or
developmental toxicity was seen in an oral (gavage) developmental
toxicity study in rats with fatty alcohol blend at doses up to 1,000
mg/kg/day. Aliphatic alcohols gave a negative response for mutagenicity
in the available studies. No long term studies or carcinogenicity
studies are available in the database via oral routes of exposure.
However, as a class, the straight chain aliphatic alcohols are not
considered carcinogenic. In addition, the Agency used a qualitative
structure activity relationship (QSAR) database, DEREK11, to determine
if there were structural alerts suggestive of carcinogenicity. No
structural alerts for carcinogenicity were identified.
[[Page 6344]]
No neurotoxicity studies are available in the database. The
clinical signs suggestive of neurotoxicity were observed following a
single high bolus dose and/or repeated high bolus doses. These signs
were transient and considered due to bolus dosing.
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to n-octyl and n-decyl alcohol, EPA considered exposure under
the proposed exemption from the requirement of a tolerance. EPA
assessed dietary exposures from n-octy and n-decyl alcohol in food as
follows:
i. Acute exposure. No adverse effects attributable to a single
exposure of n-octyl alcohol and n-dectyl alcohol were seen in the
available toxicity studies. Therefore, an acute dietary risk assessment
for n-octyl and n-decyl alcohol was not conducted.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment, EPA used food consumption information from the U.S.
Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII). As to residue
levels in food, no residue data were submitted for n-octyl and n-decyl
alcohol. In the absence of specific residue data, EPA has developed an
approach which uses surrogate information to derive upper bound
exposure estimates for the subject inert ingredients. Upper bound
exposure estimates are based on the highest tolerance for a given
commodity from a list of high-use insecticides, herbicides, and
fungicides. A complete description of the general approach taken to
assess inert ingredient risks in the absence of residue data is
contained in the memorandum entitled ``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.
In the dietary exposure assessment, the Agency assumed that the
residue level of the inert ingredient would be no higher than the
highest tolerance for a given commodity. Implicit in this assumption is
that there would be similar rates of degradation (if any) between the
active and inert ingredient and that the concentration of inert
ingredient in the scenarios leading to these highest of tolerances
would be no higher than the concentration of the active ingredient.
The Agency believes the assumptions used to estimate dietary
exposures lead to an extremely conservative assessment of dietary risk
due to a series of compounded conservatisms. First, assuming that the
level of residue for an inert ingredient is equal to the level of
residue for the active ingredient will overstate exposure. The
concentration of active ingredient in agricultural products is
generally at least 50 percent of the product and often can be much
higher. Further, pesticide products rarely have a single inert
ingredient; rather, there is generally a combination of different inert
ingredients used which additionally reduces the concentration of any
single inert ingredient in the pesticide product in relation to that of
the active ingredient.
Second, the conservatism of this methodology is compounded by EPA's
decision to assume that, for each commodity, the active ingredient
which will serve as a guide to the potential level of inert ingredient
residues is the active ingredient with the highest tolerance level.
This assumption overstates residue values because it would be highly
unlikely, given the high number of inert ingredients, that a single
inert ingredient or class of ingredients would be present at the level
of the active ingredient in the highest tolerance for every commodity.
Finally, a third compounding conservatism is EPA's assumption that all
foods contain the inert ingredient at the highest tolerance level. In
other words, EPA assumed 100 percent of all foods are treated with the
inert ingredient at the rate and manner necessary to produce the
highest residue legally possible for an active ingredient. In summary,
EPA chose a very conservative method for estimating what level of inert
residue could be on food, and then used this methodology to choose the
highest possible residue that could be found on food and assumed that
all food contained this residue. No consideration was given to
potential degradation between harvest and consumption even though
monitoring data shows that tolerance level residues are typically 1 to
2 orders of magnitude higher than actual residues in food when
distributed in commerce.
Accordingly, although sufficient information to quantify actual
residue levels in food is not available, the compounding of these
conservative assumptions will lead to a significant exaggeration of
actual exposures. EPA does not believe that this approach
underestimates exposure in the absence of residue data.
iii. Cancer. The Agency used a qualitative structure activity
relationship (QSAR) database, DEREK11, to determine if there were
structural alerts suggestive of carcinogenicity. No structural alerts
for carcinogenicity were identified. Therefore, a quantitative dietary
exposure assessment was not conducted for the purpose of evaluating
cancer risk.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue and or PCT information in the dietary assessment
for n-octyl and n-decyl alcohol. Tolerance level residues and/or 100
PCT were assumed for all food commodities.
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, a conservative
drinking water concentration value of 100 parts per billion (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). Due to
the low hazard profile and lack of endpoint selection for the dermal
route of exposure, no post application dermal risk was assessed.
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 n-octyl and n-decyl alcohols to share a common
mechanism of toxicity with any other substances, and does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that n-
octyl and n-decyl alcohol do not have a common mechanism of toxicity
with other substances. For information regarding EPA's efforts to
determine which chemicals have a common mechanism of toxicity and to
evaluate the cumulative effects of such chemicals, see EPA's Web site
at https://www.epa.gov/pesticides/cumulative.
[[Page 6345]]
C. Safety Factor for Infants and Children
Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an
additional tenfold (10X) margin of safety for infants and children in
the case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the database on toxicity and exposure
unless EPA determines, based on reliable data, that a different margin
of safety will be safe for infants and children. This additional margin
of safety is commonly referred to as the Food Quality Protection Act
Safety Factor (FQPA 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. EPA has determind that reliable data show the safety of infants
and children would be adequately protected if the FQPA SF were reduced
to 1X. The decision is based on the following findings:
1. The database on n-octyl alcohol and n-decyl alcohol is
considered adequate for FQPA assessment. The database includes two
developmental toxicity studies in rats via oral route of exposure, one
developmental toxicity study in rats via inhalation routes and one
Organization of Economic Development (OECD) 422 study (reproductive and
developmental screening study) in rats. In addition, there are a 90-day
dermal toxicity study in rats and several mutagenicity studies.
2. There is no evidence of increased susceptibility of infants and
children from exposure to low chain aliphatic alcohols. In
developmental toxicity studies in rats via the oral route, no
developmental toxicity was seen at doses 1,000 mg/kg/day and above. No
developmental or systemic toxicity was seen in the developmental
toxicity study in rats via the inhalation route of exposure. No
evidence of fetal or systemic toxicity was seen at doses up to 2,000
mg/kg/day in the OECD 422 study in rats.
3. There is no indication in the database that n-octyl and n-decyl
alcohols are neurotoxic chemicals except when administered in high
bolus doses. Therefore, there is no need for a developmental
neurotoxicity study. There is no indication of immunotoxicity in the
available database; therefore, an immunotoxicity study is not required.
4. There are no long-term studies in the database but there are no
concerns for the lack of such data because the available studies
indicate that no systemic toxicity was seen at the limit dose or above
except in one developmental gavage study in rats in which the
salivation was seen at the high dose of 1,000 mg/kg/day. This effect is
considered to be due to bolus gavage dosing. This study and endpoint
was used for the chronic reference dose (RfD), therefore, providing
conservative estimates.
5. There are no residual uncertainties identified in the exposure
databases. The food and drinking water assessment is not likely to
underestimate exposure to any subpopulation, including those comprised
of infants and children. The dietary exposure assessments are
considered to be highly conservative as they are based on the use of
the highest tolerance level from the surrogate pesticides for every
food and 100% crop treated is assumed for all crops. EPA also made
conservative (protective) assumptions in the ground and surface water
modeling used to assess exposure to n-octyl alcohol and n-decyl alcohol
in drinking water. These assessments will not underestimate the
exposure and risks posed by both alcohols. Based on the above
considerations; EPA has reduced the FQPA factor to 1X.
D. 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 population adjusted dose (aPAD) and chronic population adjusted
dose (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 point of departures (PODs) to ensure that an
adequate margin of exposure (MOE) exists.
1. Acute aggregate (food and drinking water) risk. No adverse
effect resulting from a single oral exposure was identified and no
acute dietary endpoint was selected. Therefore, n-octyl alcohol and n-
decyl alcohol are not expected to pose an acute risk.
2. Chronic aggregate (food and drinking water) risk. A chronic
aggregate risk assessment takes into account exposure estimates from
chronic dietary consumption of food and drinking water. Using the
exposure assumptions discussed in this unit for chronic exposure, the
chronic dietary exposure from food and water to n-octyl alcohol and n-
decyl alcohol is 5.1% of the cPAD for the U.S. population and 16.6% of
the cPAD for children 1-2 years old, the most highly exposed population
subgroup. The chronic dietary exposure estimates for food and drinking
water are below the Agency's level of concern (<100% cPAD) for the U.S.
population and all population subgroups.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Short- term
quantitative aggregate risk assessment was not conducted because there
is low hazard via the oral, dermal and inhalation routes of exposure.
The endpoint of concern for the chronic RfD was based on the
conservative NOAEL of 375 mg/kg/day. This NOAEL was based on salivation
seen at the LOAEL of 1,000 mg/kg/day in a developmental toxicity study
in rats. The dietary exposure from food and water is estimated to be
5.1% of the cPAD. The short-term residential exposure is not expected
to be 95% of the cPAD because dermal and inhalation exposures are not
likely to be significant since the alcohols will be readily volatized
and dissipated in the environment. Therefore, aggregate short-term
exposure does not pose a risk 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). Intermediate-term quantitative aggregate risk assessment was
not conducted because there is low hazard via the oral, dermal and
inhalation routes of exposure. The endpoint of concern for the chronic
RfD was based on the conservative NOAEL of 375 mg/kg/day. This NOAEL
was based on salivation seen at the LOAEL of 1,000 mg/kg/day in a
developmental toxicity study in rats. The dietary exposure from food
and water is estimated to be 5.1% of the cPAD. The intermediate-term
residential exposure is not expected to be 95% of the cPAD because
dermal and inhalation exposure are not likely to be significant since
the alcohols will be readily volatized and dissipated in the
environment. Therefore quantitative short-term residential exposure
assessment was not conducted.
5. Aggregate cancer risk for U.S. population. The Agency has not
identified any concerns for carcinogenicity relating to n-octyl alcohol
and n-decyl alcohol.
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 n-octyl alcohol and n-decyl alcohol residues.
[[Page 6346]]
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 residue of n-
octyl alcohol and n-decyl alcohol in or any food commodities.
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 n-octyl and n-decyl
alcohol.
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.910 for of n-octyl alcohol (CAS Reg. No.
111-87-5); and n-decyl alcohol (CAS Reg. No. 112-30-1) when used as an
inert ingredient (solvent or co-solvent) in pesticide formulations
applied to growing crops or to raw agricultural commodities after
harvest under 40 CFR 180.910.
VII. Statutory and Executive Order Reviews
This final rule establishes an exemption from the requirement of 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 exemptions 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
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) (Pub. L. 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).
