I. General Information
A. Does this Action Apply to Me?
SUMMARY: This regulation establishes
exemptions from the requirement of a
tolerance for residues of N,Ndimethyloctanamide or octanamide,
N,N-dimethyl (CAS Reg. No. 1118–92–
9), and N,N-dimethyldecanamide or
decanamide, N,N-dimethyl (CAS Reg.
No. 14433–76–2) when used as inert
ingredients (emulsifier, solvent, and
cosolvent) in pesticide formulations
applied only to growing crops. The C.P.
Hall Company, now doing business as
CPH Services, submitted a petition to
EPA under the Federal Food, Drug, and
Cosmetic Act (FFDCA), as amended by
the Food Quality Protection Act of 1996
(FQPA), requesting an exemption from
the requirement of a tolerance. This
regulation eliminates the need to
establish a maximum permissible level
for residues of N,N-dimethyloctanamide
and N,N-dimethyldecanamide.
DATES: This regulation is effective
February 16, 2005. Objections and
requests for hearings must be received
on or before April 18, 2005.
ADDRESSES: To submit a written
objection or hearing request follow the

II. Background and Statutory Findings
In the Federal Register of November
15, 2001 (66 FR 57450) (FRL–6808–6),
EPA issued a notice pursuant to section
408 of the FFDCA, 21 U.S.C. 346a, as
amended by the FQPA (Public Law 104–
170), announcing the filing of a
pesticide petition (PP 1E6257) by The
C.P. Hall Company, 311 S. Wacker,
Suite 4700, Chicago, IL 60606, now
doing business as CPH Services. The
petition requested that 40 CFR part 180
be amended by establishing exemptions
from the requirement of a tolerance for
PO 00000
Frm 00057
Fmt 4700
Sfmt 4700
7895
residues of N,N-dimethyloctanamide
(CAS Reg. No. 1118–92–9) and N,Ndimethyldecanamide (CAS Reg. No.
14433–76–2) when used as inert
ingredients as an emulsifier, solvent,
and cosolvent in pesticide formulations
applied only to growing crops at less
than 15% of the total formulation by
weight. That notice included a summary
of the petition prepared by the
petitioner.
In 2003, EPA received an amendment
to the pending PP 1E6257. Subsequent
to the publication of that notice of filing,
the petitioner requested to amend the
pending pesticide petition to remove the
15% limitation on the percentage of
N,N-dimethyloctanamide and N,Ndimethyldecanamide used in
formulated products. There were no
other changes to the information
presented by the petitioner in the 2001
notice. The amended notice was
published in the Federal Register of
November 19, 2003 (68 FR 65279) (FRL–
7332–6). There were no comments
received in response to either of the
notices of filing.
Section 408(b)(2)(A)(i) of the 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 the 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 the 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 performs a number of analyses to
determine the risks from aggregate
exposure to pesticide residues. First,
EPA determines the toxicity of
pesticides. Second, EPA examines
exposure to the pesticide through food,
drinking water, and through other
exposures that occur as a result of
pesticide use in residential settings.
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
E:\FR\FM\16FER1.SGM
16FER1
7896
Federal Register / Vol. 70, No. 31 / Wednesday, February 16, 2005 / Rules and Regulations
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. Toxicological Profile
Consistent with section 408(b)(2)(D)
of the FFDCA, EPA has reviewed the
available scientific data and other
relevant information in support of this
action and considered its validity,
completeness and reliability and the
relationship of this information 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. The
nature of the toxic effects caused by
N,N-dimethyloctanamide and N,Ndimethyldecanamide are discussed in
this unit.
A. Submitted Studies
The petitioner has also submitted
information to the Agency as part of the
High Production Volume Challenge
Program. According to that information,
N,N-dimethyldecanamide (CAS No.
14433–76–2) is produced commercially
in a purified form (98%) as Hallcomid
M–10. N,N-dimethyloctanamide (CAS
No. 1118–92–9) and N,Ndimethyldecanamide are produced as a
commercial mixture, Hallcomid M–8–
10, containing 50–65% N,Ndimethyloctanamide, 37–50% of N,Ndimethyldecanamide, 0–5% N,Ndimethylhexanamide, and 0–2% N,Ndimethyldodecanamide.
The test substance for all of the
studies reviewed by the Agency was
identified as Hallcomid M–8–10. Thus,
both the N,N-dimethyloctanamide and
N,N-dimethyldecanamide were present
in the test substance. Given that the
octanamide and decanamide differ only
in the carbon length (C8 versus C10) of
the alkyl chain, the two chemicals can
be considered as surrogates for each
other.
The acute toxicity profile is presented

B. Structure Activity Relationship (SAR)
Assessment
labeling and the use of protective
equipment.
Toxicity for N,N-dimethyloctanamide
and several structurally-related analogs
was assessed, in part, by a process
called SAR. In this process, the
chemical’s structural similarity to other
chemicals (for which data are available)
is used to determine toxicity. For
human health, this process, can be used
to assess absorption and metabolism,
mutagenicity, carcinogenicity,
developmental and reproductive effects,
neurotoxicity, systemic effects,
immunotoxicity, and sensitization and
irritation. This is a qualitative
assessment using terms such as good,
not likely, poor, moderate, or high.
Since N,N-dimethyldecanamide is of a
chain length intermediate between N,Ndimethyloctanamide and the analogs
assessed, the SAR conclusions also
apply to N,N-dimethyloctanamide.
The SAR conclusions were as follows:
Absorption would be poor via all routes
of exposure. Thus, no significant effects
are expected. The SAR did indicate
concerns that one of the analogs might
be an irritant. These concerns can be
appropriately addressed through
C. Conclusions
The acute toxicity data indicated that
N,N-dimethyloctanamide and N,Ndimethyldecanamide are eye and
dermal irritants.
Subchronic toxicity studies revealed
no significant treatment related effects
for N,N-dimethyloctanamide and N,Ndimethyldecanamide. In the 6-week oral
gavage study in dogs, there were no
significant differences between treated
and control groups. During a 90-day oral
toxicity study in rats, N,Ndimethyloctanamide and N,Ndimethyldecanamide did not produce
any significant effects on mortality,
clinical signs, food consumption,
hematology, or gross pathology. In the 5day inhalation study, test animals
exhibited signs of respiratory tract
irritation. However, this respiratory
irritant effect occurred only at high
inhalation doses.
N,N-dimethyloctanamide and N,Ndimethyldecanamide showed no
evidence of mutagenicity, or
chromosome aberration, and did not
show any signs of developmental

toxicity in the study in rabbits at dose
levels up to 1,000 mg/kg/day. In a rat
developmental toxicity study there was
a decrease in weight gain in the high
dose group, which could possibly be
explained by a decrease in food
consumption. It is noted that the SAR
did not identify any developmental or
reproductive concerns.
There is a consistent pattern of
NOAELs of 100 mg/kg/day or greater in
both subchronic toxicity studies and the
maternal NOAELs in the developmental
toxicity studies. But, the effects noted
were not clinically or toxicologically
relevant especially when compared to
the control groups. These effects were
mainly decreased weight gain in all
species tested, but this occurred in such
a small number of animals that it was
not even statistically significant. Also,
there was a corresponding decrease in
food consumption. Additionally, it is
noted that the spacing between the
NOAELs and LOAELs is large.
V. Aggregate Exposures
In examining aggregate exposure,
section 408 of the FFDCA directs EPA
to consider available information
concerning exposures from the pesticide
E:\FR\FM\16FER1.SGM
16FER1
7898
Federal Register / Vol. 70, No. 31 / Wednesday, February 16, 2005 / Rules and Regulations
residue in food and all other nonoccupational exposures, including
drinking water from ground water or
surface water and exposure through
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses).
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be 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.
Both N,N-dimethyloctanamide and
N,N-dimethyldecanamide are sponsored
under the High Production Volume
Challenge Program. This is indicative of
over 1 million pounds of N,Ndimethyloctanamide and N,Ndimethyldecanamide either produced or
imported per year. Information indicates
that N,N-dimethyloctanamide and N,Ndimethyldecanamide are used in
personal care products and in paints.
The Agency has used various
screening-level models to estimate some
of the existing levels of exposure and
those that could occur as a result of
establishing this tolerance exemption.
To assure protectiveness, the estimates
in Table 4. below are deliberately
intended to over-estimate exposure.
TABLE 4.—EXPOSURE ESTIMATES FOR N,N-DIMETHYLOCTANAMIDE AND N,N-DIMETHYLDECANAMIDE
Type of Exposure
Exposure Level
Dietary - Food (as a result of application to crops)
Acute exposure: All population subgroups less than 1 mg/kg/day at 95th percentile
Chronic exposure: All population subgroups less than 1 mg/kg/day
Dietary - Drinking Water
Acute exposure: 0.0038 (child) and 0.0011 (adult) mg/kg/day
Chronic exposure: 0.00062 (child) and 0.00018 (adult) mg/kg/day
Residential (as a result of using a spray paint
product)
Acute inhalation exposure: 0.054 to 0.424 mg/kg/day
Residential (as a result of using a personal care
product)
Chronic dermal exposure: 0.00032 mg/kg/day
VI. Cumulative Effects
Section 408 (b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance or tolerance exemption, the
Agency consider ‘‘available
information’’ concerning the cumulative
effects of a particular chemical’s
residues and ‘‘other substances that
have a common mechanism of toxicity.’’
Unlike other pesticide chemicals for
which EPA has followed a cumulative
risk approach based on a common
mechanism of toxicity, EPA has not
made a common mechanism of toxicity
finding as to N,N-dimethyloctanamide
and N,N-dimethyldecanamide and any
other substances. N,Ndimethyloctanamide and N,Ndimethyldecanamide do not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that N,Ndimethyloctanamide and N,Ndimethyldecanamide 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,

determinations and procedures for
cumulating effects from substances

EPA’s website at https://www.epa.gov/
pesticides/cumulative/.
VII. Safety Factor for Infants and
Children
FFDCA section 408 provides that EPA
shall apply an additional tenfold 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 data unless EPA
concludes that a different margin of
safety will be safe for infants and
children. The Agency has reviewed the
results of two developmental toxicity
studies conducted using N,Ndimethyloctanamide and N,Ndimethyldecanamide. Based on the
observed insignificant clinical toxic
effects such as decreased weight gain
due to decreased food intake, and the
fact that developmental signs were
observed only at very high doses, EPA
has not used a safety factor analysis to
assess the risk. For the same reasons a
tenfold safety factor is unnecessary.
VIII. Determination of Safety for U.S.
Population, Infants, and Children
The Agency has reviewed and
evaluated a toxicity database of 15
PO 00000
Frm 00060
Fmt 4700
Sfmt 4700
studies conducted using N,Ndimethyloctanamide and N,Ndimethyldecanamide. Studies indicate
that N,N-dimethyloctanamide and N,Ndimethyldecanamide have a low
systemic toxicity via oral exposure and
are not mutagenic. Developmental
effects were observed only at very high
doses. The SAR assessments did not
indicate any concerns for
carcinogenicity, developmental, or
reproductive effects. Based on the
available information on toxicity and
exposure, EPA finds that exempting
N,N-dimethyloctanamide and N,Ndimethyldecanamide from the
requirement of a tolerance will be safe
for the general population including
infants and children.
IX. Other Considerations
A. Endocrine Disruptors
FQPA requires EPA to develop a
screening program to determine whether
certain substances, including all
pesticide chemicals (both inert and
active ingredients), ‘‘may have an effect
in humans that is similar to an effect
produced by a naturally occurring
estrogen, or such other endocrine effect.
. .’’ EPA has been working with
interested stakeholders to develop a
screening and testing program as well as
a priority setting scheme. As the Agency
E:\FR\FM\16FER1.SGM
16FER1
Federal Register / Vol. 70, No. 31 / Wednesday, February 16, 2005 / Rules and Regulations
proceeds with implementation of this
program, further testing of products
containing N,N-dimethyloctanamide
and N,N-dimethyldecanamide for
endocrine effects may be required.
B. Analytical Method(s)
An analytical method is not required
for enforcement purposes since the
Agency is establishing an exemption
from the requirement of a tolerance
without any numerical limitation.
C. Existing Exemptions
There are no existing tolerances or
tolerance exemptions for N,Ndimethyloctanamide and N,Ndimethyldecanamide.
D. International Tolerances
The Agency is not aware of any
country requiring a tolerance for N,Ndimethyloctanamide and N,Ndimethyldecanamide nor have any
CODEX Maximum Residue Levels
(MRLs) been established for any food
crops at this time.
X. Conclusions
Based on the information in this
preamble, EPA concludes that there is a
reasonable certainty of no harm from
aggregate exposure to residues of N,Ndimethyloctanamide or octanamide,
N,N-dimethyl (CAS Reg. No. 1118–92–
9), and N,N-dimethyldecanamide or
decanamide, N,N-dimethyl (CAS Reg.
No. 14433–76–2). Accordingly, EPA
finds that exempting octanamide, N,Ndimethyl (CAS Reg. No. 1118–92–9) and
decanamide, N,N-dimethyl (CAS Reg.
No. 14433–76–2) from the requirement
of a tolerance will be safe.
XI. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as
amended by the FQPA, any person may
file an objection to any aspect of this
regulation and may also request a
hearing on those objections. The EPA
procedural regulations which govern the
submission of objections and requests
for hearings appear in 40 CFR part 178.
Although the procedures in those
regulations require some modification to
reflect the amendments made to the
FFDCA by the FQPA, EPA will continue
to use those procedures, with
appropriate adjustments, until the
necessary modifications can be made.
The new section 408(g) of the FFDCA
provides essentially the same process
for persons to ‘‘object’’ to a regulation
for an exemption from the requirement
of a tolerance issued by EPA under new
section 408(d) of the FFDCA, as was
provided in the old FFDCA sections 408
and 409 of the FFDCA. However, the
VerDate jul<14>2003

Jkt 205001
period for filing objections is now 60
days, rather than 30 days.

B. When Will the Agency Grant a
Request for a Hearing?
A request for a hearing will be granted
if the Administrator determines that the
material submitted shows the following:
There is a genuine and substantial issue
of fact; there is a reasonable possibility
that available evidence identified by the
requestor would, if established resolve
one or more of such issues in favor of
the requestor, taking into account
uncontested claims or facts to the
contrary; and resolution of the factual
issues(s) in the manner sought by the
requestor would be adequate to justify
the action requested (40 CFR 178.32).
XII. Statutory and Executive Order
Reviews
This final rule establishes an
exemption from the tolerance
requirement under section 408(d) of the
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 rule has been exempted
from review under Executive Order
12866 due to its lack of significance,
this rule is not subject to Executive
Order 13211, Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66
FR 28355, May 22, 2001). 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., or impose
any enforceable duty or contain any
unfunded mandate as described under
Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public
Law 104–4). 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); or OMB review or any Agency
action under Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety

7900
Federal Register / Vol. 70, No. 31 / Wednesday, February 16, 2005 / Rules and Regulations
Risks (62 FR 19885, April 23, 1997).
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). Since
tolerances and exemptions that are
established on the basis of a petition
under section 408(d) of the FFDCA,
such as the exemption in this final rule,
do not require the issuance of a
proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply. In
addition, the Agency has determined
that this action will not have a
substantial direct effect on States, on the
relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires
EPA to develop an accountable process
to ensure ‘‘meaningful and timely input
by State and local officials in the
development of regulatory policies that
have federalism implications.’’ ‘‘Policies
that have federalism implications’’ is
defined in the Executive order to
include regulations that have
‘‘substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.’’ This final rule
directly regulates growers, food
processors, food handlers and food
retailers, not States. This action does not
alter the relationships or distribution of
power and responsibilities established
by Congress in the preemption
provisions of section 408(n)(4) of the
FFDCA. For these same reasons, the
Agency has determined that this rule
does not have any ‘‘tribal implications’’
as described in Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive
Order 13175, requires EPA to develop
an accountable process to ensure
‘‘meaningful and timely input by tribal
officials in the development of
regulatory policies that have tribal
implications.’’ ‘‘Policies that have tribal
implications’’ is defined in the
Executive order to include regulations
that have ‘‘substantial direct effects on
one or more Indian tribes, on the
relationship between the Federal
Government and the Indian tribes, or on
VerDate jul<14>2003
10:50 Feb 15, 2005
Jkt 205001
the distribution of power and
responsibilities between the Federal
Government and Indian tribes.’’ This
rule will not have substantial direct
effects on tribal governments, on the
relationship between the Federal
Government and Indian tribes, or on the
distribution of power and
responsibilities between the Federal
Government and Indian tribes, as
specified in Executive Order 13175.
Thus, Executive Order 13175 does not
apply to this rule.
XIII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, 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).

[OPP-2005-0031; FRL-7698-3]
Octanamide, N,N-dimethyl and Decanamide, N,N-dimethyl; Exemptions
from the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes exemptions from the requirement of
a tolerance for residues of N,N-dimethyloctanamide or octanamide, N,N-
dimethyl (CAS Reg. No. 1118-92-9), and N,N-dimethyldecanamide or
decanamide, N,N-dimethyl (CAS Reg. No. 14433-76-2) when used as inert
ingredients (emulsifier, solvent, and cosolvent) in pesticide
formulations applied only to growing crops. The C.P. Hall Company, now
doing business as CPH Services, submitted a petition to EPA under the
Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food
Quality Protection Act of 1996 (FQPA), requesting an exemption from the
requirement of a tolerance. This regulation eliminates the need to
establish a maximum permissible level for residues of N,N-
dimethyloctanamide and N,N-dimethyldecanamide.
DATES: This regulation is effective February 16, 2005. Objections and
requests for hearings must be received on or before April 18, 2005.
ADDRESSES: To submit a written objection or hearing request follow the

II. Background and Statutory Findings
In the Federal Register of November 15, 2001 (66 FR 57450) (FRL-
6808-6), EPA issued a notice pursuant to section 408 of the FFDCA, 21
U.S.C. 346a, as amended by the FQPA (Public Law 104-170), announcing
the filing of a pesticide petition (PP 1E6257) by The C.P. Hall
Company, 311 S. Wacker, Suite 4700, Chicago, IL 60606, now doing
business as CPH Services. The petition requested that 40 CFR part 180
be amended by establishing exemptions from the requirement of a
tolerance for residues of N,N-dimethyloctanamide (CAS Reg. No. 1118-92-
9) and N,N-dimethyldecanamide (CAS Reg. No. 14433-76-2) when used as
inert ingredients as an emulsifier, solvent, and cosolvent in pesticide
formulations applied only to growing crops at less than 15% of the
total formulation by weight. That notice included a summary of the
petition prepared by the petitioner.
In 2003, EPA received an amendment to the pending PP 1E6257.
Subsequent to the publication of that notice of filing, the petitioner
requested to amend the pending pesticide petition to remove the 15%
limitation on the percentage of N,N-dimethyloctanamide and N,N-
dimethyldecanamide used in formulated products. There were no other
changes to the information presented by the petitioner in the 2001
notice. The amended notice was published in the Federal Register of
November 19, 2003 (68 FR 65279) (FRL-7332-6). There were no comments
received in response to either of the notices of filing.
Section 408(b)(2)(A)(i) of the 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 the 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 the 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 performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First, EPA determines the
toxicity of pesticides. Second, EPA examines exposure to the pesticide
through food, drinking water, and through other exposures that occur as
a result of pesticide use in residential settings.
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
[[Page 7896]]
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. Toxicological Profile
Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed
the available scientific data and other relevant information in support
of this action and considered its validity, completeness and
reliability and the relationship of this information 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. The nature of the toxic effects caused
by N,N-dimethyloctanamide and N,N-dimethyldecanamide are discussed in
this unit.
A. Submitted Studies
The petitioner has also submitted information to the Agency as part
of the High Production Volume Challenge Program. According to that
information, N,N-dimethyldecanamide (CAS No. 14433-76-2) is produced
commercially in a purified form (98%) as Hallcomid M-10. N,N-
dimethyloctanamide (CAS No. 1118-92-9) and N,N-dimethyldecanamide are
produced as a commercial mixture, Hallcomid M-8-10, containing 50-65%
N,N-dimethyloctanamide, 37-50% of N,N-dimethyldecanamide, 0-5% N,N-
dimethylhexanamide, and 0-2% N,N-dimethyldodecanamide.
The test substance for all of the studies reviewed by the Agency
was identified as Hallcomid M-8-10. Thus, both the N,N-
dimethyloctanamide and N,N-dimethyldecanamide were present in the test
substance. Given that the octanamide and decanamide differ only in the
carbon length (C8 versus C10) of the alkyl chain, the two chemicals can
be considered as surrogates for each other.
The acute toxicity profile is presented in Table 1. below:

B. Structure Activity Relationship (SAR) Assessment
Toxicity for N,N-dimethyloctanamide and several structurally-
related analogs was assessed, in part, by a process called SAR. In this
process, the chemical's structural similarity to other chemicals (for
which data are available) is used to determine toxicity. For human
health, this process, can be used to assess absorption and metabolism,
mutagenicity, carcinogenicity, developmental and reproductive effects,
neurotoxicity, systemic effects, immunotoxicity, and sensitization and
irritation. This is a qualitative assessment using terms such as good,
not likely, poor, moderate, or high. Since N,N-dimethyldecanamide is of
a chain length intermediate between N,N-dimethyloctanamide and the
analogs assessed, the SAR conclusions also apply to N,N-
dimethyloctanamide.
The SAR conclusions were as follows: Absorption would be poor via
all routes of exposure. Thus, no significant effects are expected. The
SAR did indicate concerns that one of the analogs might be an irritant.
These concerns can be appropriately addressed through labeling and the
use of protective equipment.
C. Conclusions
The acute toxicity data indicated that N,N-dimethyloctanamide and
N,N-dimethyldecanamide are eye and dermal irritants.
Subchronic toxicity studies revealed no significant treatment
related effects for N,N-dimethyloctanamide and N,N-dimethyldecanamide.
In the 6-week oral gavage study in dogs, there were no significant
differences between treated and control groups. During a 90-day oral
toxicity study in rats, N,N- dimethyloctanamide and N,N-
dimethyldecanamide did not produce any significant effects on
mortality, clinical signs, food consumption, hematology, or gross
pathology. In the 5-day inhalation study, test animals exhibited signs
of respiratory tract irritation. However, this respiratory irritant
effect occurred only at high inhalation doses.
N,N-dimethyloctanamide and N,N-dimethyldecanamide showed no
evidence of mutagenicity, or chromosome aberration, and did not show
any signs of developmental toxicity in the study in rabbits at dose
levels up to 1,000 mg/kg/day. In a rat developmental toxicity study
there was a decrease in weight gain in the high dose group, which could
possibly be explained by a decrease in food consumption. It is noted
that the SAR did not identify any developmental or reproductive
concerns.
There is a consistent pattern of NOAELs of 100 mg/kg/day or greater
in both subchronic toxicity studies and the maternal NOAELs in the
developmental toxicity studies. But, the effects noted were not
clinically or toxicologically relevant especially when compared to the
control groups. These effects were mainly decreased weight gain in all
species tested, but this occurred in such a small number of animals
that it was not even statistically significant. Also, there was a
corresponding decrease in food consumption. Additionally, it is noted
that the spacing between the NOAELs and LOAELs is large.
V. Aggregate Exposures
In examining aggregate exposure, section 408 of the FFDCA directs
EPA to consider available information concerning exposures from the
pesticide
[[Page 7898]]
residue in food and all other non-occupational exposures, including
drinking water from ground water or surface water and exposure through
pesticide use in gardens, lawns, or buildings (residential and other
indoor uses).
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be 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.
Both N,N-dimethyloctanamide and N,N-dimethyldecanamide are
sponsored under the High Production Volume Challenge Program. This is
indicative of over 1 million pounds of N,N-dimethyloctanamide and N,N-
dimethyldecanamide either produced or imported per year. Information
indicates that N,N-dimethyloctanamide and N,N-dimethyldecanamide are
used in personal care products and in paints.
The Agency has used various screening-level models to estimate some
of the existing levels of exposure and those that could occur as a
result of establishing this tolerance exemption. To assure
protectiveness, the estimates in Table 4. below are deliberately
intended to over-estimate exposure.

dimethyldecanamide

Chronic exposure: All population

------------------------------------------------------------------------
-------------------------------------===================================
------------------------------------------------------------------------
VI. Cumulative Effects
Section 408 (b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance or tolerance
exemption, the Agency consider ``available information'' concerning the
cumulative effects of a particular chemical's residues and ``other
substances that have a common mechanism of toxicity.''
Unlike other pesticide chemicals for which EPA has followed a
cumulative risk approach based on a common mechanism of toxicity, EPA
has not made a common mechanism of toxicity finding as to N,N-
dimethyloctanamide and N,N-dimethyldecanamide and any other substances.
N,N-dimethyloctanamide and N,N-dimethyldecanamide do not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has not assumed that
N,N-dimethyloctanamide and N,N-dimethyldecanamide 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
the policy statements released by EPA's Office of Pesticide Programs
(OPP) concerning common mechanism determinations and procedures for
cumulating effects from substances found to have a common mechanism on
EPA's website at https://www.epa.gov/pesticides/cumulative/.
VII. Safety Factor for Infants and Children
FFDCA section 408 provides that EPA shall apply an additional
tenfold 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 data unless EPA concludes that a different
margin of safety will be safe for infants and children. The Agency has
reviewed the results of two developmental toxicity studies conducted
using N,N-dimethyloctanamide and N,N-dimethyldecanamide. Based on the
observed insignificant clinical toxic effects such as decreased weight
gain due to decreased food intake, and the fact that developmental
signs were observed only at very high doses, EPA has not used a safety
factor analysis to assess the risk. For the same reasons a tenfold
safety factor is unnecessary.
VIII. Determination of Safety for U.S. Population, Infants, and
Children
The Agency has reviewed and evaluated a toxicity database of 15
studies conducted using N,N-dimethyloctanamide and N,N-
dimethyldecanamide. Studies indicate that N,N-dimethyloctanamide and
N,N-dimethyldecanamide have a low systemic toxicity via oral exposure
and are not mutagenic. Developmental effects were observed only at very
high doses. The SAR assessments did not indicate any concerns for
carcinogenicity, developmental, or reproductive effects. Based on the
available information on toxicity and exposure, EPA finds that
exempting N,N-dimethyloctanamide and N,N-dimethyldecanamide from the
requirement of a tolerance will be safe for the general population
including infants and children.
IX. Other Considerations
A. Endocrine Disruptors
FQPA requires EPA to develop a screening program to determine
whether certain substances, including all pesticide chemicals (both
inert and active ingredients), ``may have an effect in humans that is
similar to an effect produced by a naturally occurring estrogen, or
such other endocrine effect. . .'' EPA has been working with interested
stakeholders to develop a screening and testing program as well as a
priority setting scheme. As the Agency
[[Page 7899]]
proceeds with implementation of this program, further testing of
products containing N,N-dimethyloctanamide and N,N-dimethyldecanamide
for endocrine effects may be required.
B. Analytical Method(s)
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
C. Existing Exemptions
There are no existing tolerances or tolerance exemptions for N,N-
dimethyloctanamide and N,N-dimethyldecanamide.
D. International Tolerances
The Agency is not aware of any country requiring a tolerance for
N,N-dimethyloctanamide and N,N-dimethyldecanamide nor have any CODEX
Maximum Residue Levels (MRLs) been established for any food crops at
this time.
X. Conclusions
Based on the information in this preamble, EPA concludes that there
is a reasonable certainty of no harm from aggregate exposure to
residues of N,N-dimethyloctanamide or octanamide, N,N-dimethyl (CAS
Reg. No. 1118-92-9), and N,N-dimethyldecanamide or decanamide, N,N-
dimethyl (CAS Reg. No. 14433-76-2). Accordingly, EPA finds that
exempting octanamide, N,N-dimethyl (CAS Reg. No. 1118-92-9) and
decanamide, N,N-dimethyl (CAS Reg. No. 14433-76-2) from the requirement
of a tolerance will be safe.
XI. Objections and Hearing Requests
Under section 408(g) of the FFDCA, as amended by the FQPA, any
person may file an objection to any aspect of this regulation and may
also request a hearing on those objections. The EPA procedural
regulations which govern the submission of objections and requests for
hearings appear in 40 CFR part 178. Although the procedures in those
regulations require some modification to reflect the amendments made to
the FFDCA by the FQPA, EPA will continue to use those procedures, with
appropriate adjustments, until the necessary modifications can be made.
The new section 408(g) of the FFDCA provides essentially the same
process for persons to ``object'' to a regulation for an exemption from
the requirement of a tolerance issued by EPA under new section 408(d)
of the FFDCA, as was provided in the old FFDCA sections 408 and 409 of
the FFDCA. However, the period for filing objections is now 60 days,
rather than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must
identify docket ID number OPP-2005-0031 in the subject line on the
first page of your submission. All requests must be in writing, and
must be mailed or delivered to the Hearing Clerk on or before April 18,
2005.
1. Filing the request. Your objection must specify the specific
provisions in the regulation that you object to, and the grounds for
the objections (40 CFR 178.25). If a hearing is requested, the
objections must include a statement of the factual issues(s) on which a
hearing is requested, the requestor's contentions on such issues, and a
summary of any evidence relied upon by the objector (40 CFR 178.27).
Information submitted in connection with an objection or hearing
request may be claimed confidential by marking any part or all of that
information as CBI. Information so marked will not be disclosed except
in accordance with procedures set forth in 40 CFR part 2. A copy of the
information that does not contain CBI must be submitted for inclusion
in the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice.
Mail your written request to: Office of the Hearing Clerk (1900L),
Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. You may also deliver your request to the
Office of the Hearing Clerk in Suite 350, 1099 14\th\ St., NW.,
Washington, DC 20005. The Office of the Hearing Clerk is open from 8
a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The
telephone number for the Office of the Hearing Clerk is (202) 564-6255.
2. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit XI.A., you
should also send a copy of your request to the PIRIB for its inclusion
in the official record that is described in ADDRESSES. Mail your
copies, identified by docket ID number OPP-2005-0031, to: Public
Information and Records Integrity Branch, Information Resources and
Services Division (7502C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001. In person or by courier, bring a copy to the location of the
PIRIB described in ADDRESSES. You may also send an electronic copy of
your request via e-mail to: opp-docket@epa.gov. Please use an ASCII
file format and avoid the use of special characters and any form of
encryption. Copies of electronic objections and hearing requests will
also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format.
Do not include any CBI in your electronic copy. You may also submit an
electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).
XII. Statutory and Executive Order Reviews
This final rule establishes an exemption from the tolerance
requirement under section 408(d) of the 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 rule has been exempted from review under Executive
Order 12866 due to its lack of significance, this rule is not subject
to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001). 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., or impose any enforceable duty or
contain any unfunded mandate as described under Title II of the
Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). 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);
or OMB review or any Agency action under Executive Order 13045,
entitled Protection of Children from Environmental Health Risks and
Safety
[[Page 7900]]
Risks (62 FR 19885, April 23, 1997). 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). Since tolerances and
exemptions that are established on the basis of a petition under
section 408(d) of the FFDCA, such as the exemption in this final rule,
do not require the issuance of a proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply.
In addition, the Agency has determined that this action will not have a
substantial direct effect on States, on the relationship between the
national government and the States, or on the distribution of power and
responsibilities among the various levels of government, as specified
in Executive Order 13132, entitled Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires EPA to develop an accountable
process to ensure ``meaningful and timely input by State and local
officials in the development of regulatory policies that have
federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency
has determined that this rule does not have any ``tribal implications''
as described in Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000). Executive Order 13175, requires EPA to develop an accountable
process to ensure ``meaningful and timely input by tribal officials in
the development of regulatory policies that have tribal implications.''
``Policies that have tribal implications'' is defined in the Executive
order to include regulations that have ``substantial direct effects on
one or more Indian tribes, on the relationship between the Federal
Government and the Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.''
This rule will not have substantial direct effects on tribal
governments, on the relationship between the Federal Government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes, as specified in
Executive Order 13175. Thus, Executive Order 13175 does not apply to
this rule.
XIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
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).
