Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
VII. 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

II. Background and Statutory Findings
In the Federal Register of August 8,
2007 (72 FR 44521) (FRL–8139–7), EPA
issued a notice pursuant to section
408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide tolerance petition (PP 7F7186)
by Falcon Lab, LLC, 1103 Norbee Drive,
Wilmington, DE 19803. The petition
requested that 40 CFR part 180 be
amended by establishing an exemption
from the requirement of a tolerance for
residues of ammonium soap salts of
higher fatty acids (C8–C18 saturated and
C8–C12 unsaturated). This notice failed
to include a summary of the petition
prepared by the petitioner Falcon Lab,
LLC, nor was a summary of the petition
provided in the docket for this action.
Therefore, EPA republished notice of
receipt of this petition in the Federal
Register of April 16, 2008 (73 FR 20631)
(FRL–8360–1), and posted the summary
of the petition in the docket for this
action. There were no comments
received in response to the notice of
filing.
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 exemption is ‘‘safe.’’
Section 408(c)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Pursuant to
section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an
exemption from the requirement of a
tolerance, EPA must take into account
the factors set forth in section
408(b)(2)(C) of FFDCA, which require
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.... ’’
Additionally, section 408(b)(2)(D) of
FFDCA requires that 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 performs a number of analyses to
determine the risks from aggregate
exposure to pesticide residues. First,

39266
Federal Register / Vol. 73, No. 132 / Wednesday, July 9, 2008 / Rules and Regulations
dwashington3 on PRODPC61 with RULES
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. Toxicological Profile
Consistent with section 408(b)(2)(D)
of 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.
Ammonium soap salts of fatty acids
are one class of salts of fatty acids.
Soaps are mineral salts of naturally
occurring fatty acids. The fatty acids are
a significant part of the normal daily
diet, for they occur in dietary lipids
which usually constitute about 90 grams
in a day’s diet. As discussed in this
Unit, as part of the reregistration
process, the Agency has already
conducted a risk assessment for soap
salts of fatty acids for their potential
effects to human health and the
environment and determined that all
registered pesticide products containing
the active ingredient Soap Salts are not
likely to cause unreasonable adverse
effects in people or the environment and
were eligible for reregistration.
The Agency issued a Reregistration
Eligibility Document (RED) in
September 1992 for potassium salts of
fatty acids (C12–C18 saturated and C18
unsaturated, including potassium
laureate, potassium myristate,
potassium oleate, and potassium
ricinoleate (CAS No. 10124–65–9) and
ammonium salts of fatty acids (C8–C18
saturated and C18 unsaturated, including
ammonium oleate (CAS No. 84776–33–
0). While the RED does not specifically
identify the active ingredient
ammonium nonanoate (also called
pelargonic acid) by name, the Agency
believes the conclusions of the RED are
applicable to ammonium nonanoate
because the RED defines the soap salts
of fatty acids that were assessed to be
(C8–C18) and ammonium nonanoate
(pelargonic acid) is an ammonium salt
of C9 fatty acid. All soap salts with fatty
acids having aliphatic carbon chains
lengths in the range between C8 and C18
saturated and C8–C12 unsaturated are
virtually identical in regard to chemistry
and toxicology.
In support of the RED, the Agency
conducted a risk assessment for soap
salts for their potential effects (if any) to
VerDate Aug<31>2005
15:16 Jul 08, 2008
Jkt 214001
human health. The Agency determined
that soap salts of fatty acids are
metabolized, forming simple
compounds that serve as energy sources
and structural compounds used in all
living cells, and have low acute toxicity
by the oral route of exposure. The RED
notes that soap salts of potassium salts
of coco fatty acid and sodium salts of
caprylic acid, when administered to lab
animals at high doses cause
reproductive and mutagenic effects.
However, based on the low toxicity of
ammonium nonanoate and data/
information reviewed in support of the
tolerance exemption for pelargonic acid
(ammonium nonanoate acid) which
demonstrated that pelargonic acid did
not cause developmental or mutagenic
effects, the Agency believes that there
would likely not be any reproductive or
mutagenic effects for this active
ingredient when used in the manner as
described in this rule. Further the
pesticidal concentration of ammonium
nonanoate will be exceedingly lower in
comparison to those high doses which
were administered in the studies using
potassium salts of coco fatty acids.
The active ingredient ammonium
soap salts of fatty acids, is used as a
contact, non-selective, broad spectrum,
foliar-applied herbicides. This active
ingredient was federally registered in
2006 as a non-food use pesticide for the
suppression and control of a wide
variety of undesirable grasses and
weeds. In addition, ammonium salts of
fatty acids have been registered for other
non-food uses, including repelling
rabbits and deer from forage and grain
crops, vegetables and field crops, in
orchards, and on nursery stock,
ornamentals, flower, lawns, turfs, vines,
shrubs and trees.
As part of this rulemaking, EPA
reviewed the Soap Salts of Fatty Acid
RED, the Pelargonic Acid Tolerance
Exemption (40 CFR 180.1159), the data
and/or information submitted by the
petitioner and has concluded that
ammonium nonanoate, a C9 ammonium
salt fatty acid (also called pelargonic
acid) and other ammonium soap salts of
higher fatty acids (C8–C18 saturated;
C8–C12 unsaturated) do not pose an
unreasonable adverse effect to the
environment, when used in accordance
with approved labeling. While this
pesticide is not intended to be sprayed
directly on food or feed crops, the
Agency has determined that there may
be a potential for exposure from
residues of ammonium soap salts on
food and feed as a result of
unintentional spray or drift.
In lieu of submitting new Tier I
toxicity studies for ammonium
nonanoate, the registrant relied on data
PO 00000
Frm 00054
Fmt 4700
Sfmt 4700
previously submitted in support of the
Soap Salts Registration Eligibility
Document (RED). The RED concluded
that fatty acids such as oleic acids and
related C12–C18 fatty acids are generally
considered to be low toxicity by the oral
route of exposure and gives a category
IV for both oral and dermal route of
exposure. This conclusion can be
extended to all ammonium salts of fatty
acids (C8–C18 saturated; C8–C12
unsaturated) because of the virtual
identical chemistry and toxicology of
these fatty acids.
In addition to relying on the RED, the
petitioner submitted requests for waiver
of additional studies in support of its
petition for a tolerance exemption.
1. Acute inhalation toxicity:
Ammonium salts of fatty acids do not
form aerosol particulates, have a vapor
pressure near that of water and do not
readily vaporize. ‘‘In a study in which
10 rats were exposed for 8 hours to
saturated vapors of mixed isomers of
decanoic acid (C10) no deaths were
observed.’’ MRID 43843503 reported
that the LC50 was > 1.244 milligrams/
liter (mg/L) for nonanoic acid (C9).
2. Subchronic oral toxicity: MRID
43843507 reported that no significant
effects were demonstrated in a 14–day
range finding study in rats given
nonanoic acid at doses up to 1,834 mg/
kilogram (kg)/day. ‘‘The agency
concluded that a 90–day oral toxicity
study was not necessary for a dietary
risk assessment’’ of nonanoic acid due
to the following:
i. Lack of effects at extremely high
doses in the range finding study;
ii. Nature of nonanoic acid (a fatty
acid) and its ubiquity in nature;
iii. The results from acute mammalian
toxicology studies; and
iv. The unlikelihood of prolonged
human exposure via the oral route due
to the proposed use patterns.
Dietary exposure would be minimized
via plant metabolism of ammonium
nonanoic acid through oxidative
pathways common for fatty acids. The
same rationale can be applied to
ammonium salts of fatty acids because
they share a chemical identity with
ammonium nonanoic acid.
3. Teratogenicity: MRID 43843508, a
developmental toxicity study of
nonanoic acid (C9 fatty acid), reported
that the treatment had no adverse effects
on clinical signs, body weight, or food/
water consumption. No fetal toxicity
was observed. The mean number of
viable fetuses, early or late resorptions,
implantation sites, corpora lutea, preand post-implantation losses, sex ratios
and fetal body weight were comparable
to those of the control group. The no
observed adverse effect level (NOAEL)
E:\FR\FM\09JYR1.SGM
09JYR1
Federal Register / Vol. 73, No. 132 / Wednesday, July 9, 2008 / Rules and Regulations
for maternal and developmental toxicity
was 1,500 mg/kg/day and the lowest
observed adverse effect level (LOAEL)
was > 1,500 mg/kg/day. The
developmental toxicity study for
ammonium nonanoic acid showed no
effects at dose levels above the limit
dose (1,000 mg/kg/day). Therefore, the
tier 1 data requirement for food use for
this biochemical pesticide is satisfied.
The same rationale can be applied to
ammonium salts of fatty acids because
they share a chemical identity with
ammonium nonanoic acid.
4. Immune response: This study is
conditionally required when there is a
requirement for a sub-chronic oral,
dermal, or inhalation study, depending
on the most likely routes of exposure.
The registrant requested waivers based
on the factors given for the waiver
request of the 90–day oral toxicity
study.
dwashington3 on PRODPC61 with RULES
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of FFDCA directs EPA to
consider available information
concerning exposures from the pesticide
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).
Aggregate exposure to ammonium
salts may occur via oral and dermal
routes. Since the acute oral toxicity of
soap salts is low (Toxicity Category IV),
the risks anticipated from oral
exposures are considered minimal. The
acute dermal toxicity is also low
(Toxicity Category IV). Longer dermal
exposures can produce mild to
moderate irritation, but soap salts are
not skin sensitizers. As a result, the
anticipated risks from dermal exposure
are considered minimal. Since the
inhalation route is not a likely exposure
pathway the anticipated risk from
inhalation exposure are also considered
minimal.
A. Dietary Exposure
1. Food. Pesticides containing
ammonium soap salts of fatty acids are
likely to be used as contact, nonselective, broad spectrum, foliar-applied
herbicides or as repellents. As such they
are likely not to be applied directly to
any food plants. Moreover, ammonium
salts of fatty acids are expected to be
rapidly metabolized by soil
microorganisms, with a half-life of
perhaps less than one day, therefore
residues of ammonium salts of fatty
acids when used in accordance with
approved labeling will not persist in the
VerDate Aug<31>2005
15:16 Jul 08, 2008
Jkt 214001
environment. The lack of direct
application to food plants coupled with
the rapid metabolization of ammonium
salts when used as pesticides will result
in low exposures to ammonium soap
salts of fatty acids. However, if the
exposures to ammonium soap salts to
humans from food commodities that
have been indirectly sprayed with
residues of ammonium salts occur, the
Agency does not expect exposures to be
unsafe due the low acute toxicity and
likely low exposure of these soap salts.
2. Drinking water exposure. No
significant exposure to drinking water is
expected from an accumulation of soap
salts in the aquatic environment when
it is used in accordance with approved
labeling. Ammonium salts of fatty acids
are not to be applied directly to water.
B. Other Non-Occupational Exposure
Non-occupational dermal exposure to
ammonium salts of fatty acids will be
expected since the use of this pesticide
will be in the residential settings.
However, the Agency believes that any
hazard related to exposure to residential
users from this pesticide will likely be
insignificant. This belief is based on the
fact that the toxicity data demonstrated
no toxic endpoints upon which to base
a risk characterization at or below 1,000
mg/kg of body weight/day (the limit
dose).
Non-occupational inhalation exposure
is not expected because ammonium
salts of fatty acids do not form aerosol
particulates, have a vapor pressure near
that of water, and do not readily
vaporize.
V. Cumulative Effects
Section 408(b)(2)(D)(v) of the FFDCA
requires the Agency to consider the
cumulative effect of exposure to
residues that have a common
mechanism of toxicity. These
considerations include the possible
cumulative effects of such residues on
infants and children. Except for ocular
exposure, ammonium nonanoate is of
low toxicity, and it is not anticipated
that there would be cumulative effects
from common mechanisms of toxicity.
Studies of fatty acids and fatty acid
salts previously submitted to the
Agency, indicate that the half-life of
fatty acids is less than one (1) day
(MRID 00157476). As can be expected,
there is very rapid microbial
degradation of fatty acids in soil. Fatty
acids and their salts are excellent
substrates for microbial growth, serving
both as carbon sources and energy
sources. The active ingredient cannot
totally dissipate from soil, because there
is a natural content of fatty acids in soil
resulting from plant metabolism and by
PO 00000
Frm 00055
Fmt 4700
Sfmt 4700

formation of microbial organisms. Fatty
acids constitute a significant portion of
the normal daily diet of mammals
(including humans, birds, and
invertebrates since they are found in
large amounts in the form of lipids in all
living tissues (including seeds).
Microbial metabolism of fatty acids has
the effect of either converting the
degradates to CO2 and ester (if used as
an energy source) or converting the
carbon content of the fatty acid to any
of the thousands of naturally occurring
organic substances produced by the soil
microflora (if used as a carbon source).
Based on these known facts of the role
of fatty acids in the environment and in
food and feed, there should be no
concern for cumulative effects of
ammonium salts of fatty acids used as
pesticides.
VI. Determination of Safety for U.S.
Population, Infants and Children
There is a reasonable certainty that no
harm to the U.S. population, including
infants and children , will result from
aggregate exposure to residues of
ammonium salts of fatty acids (C8–C18
saturated; C8–C12 unsaturated) due to
their use as a pesticide. This includes
all anticipated dietary exposures and all
other exposures for which there is
reliable information. As discussed in
Unit III, ammonium salts of fatty acids
(C8–C18 saturated; C8–C12 unsaturated)
have low toxicity. Moreover, many soap
salts of fatty acids are part of the human
diet and pesticide exposures are not
expected to exceed the levels of
naturally occurring fatty acids in
commonly eaten foods. Accordingly,
exempting ammonium salts of fatty
acids (C8–C18 saturated; C8–C12
unsaturated) from the requirement of a
tolerance is considered safe.
FFDCA section 408 provides that EPA
shall apply an additional tenfold margin
of exposure MOE (safety) for infants and
children in the case of threshold effects
to account for prenatal and postnatal
toxicity and the completeness of the
data base unless EPA determines that a
different margin of exposure (safety)
will be safe for infants and children.
Margins of exposure are often referred to
as uncertainty or safety factors. In this
instance, based on all available
information, the Agency concludes that
ammonium salts of fatty acids are
practically non-toxic to mammals
including infants and children. Because
there are no threshold effects of concern
to infants, children, and adults when
ammonium salt is used as labeled, the
provision requiring an additional
margin of safety does not apply. Further,
the provisions of consumption patterns,
special susceptibility, and cumulative
E:\FR\FM\09JYR1.SGM

39268
Federal Register / Vol. 73, No. 132 / Wednesday, July 9, 2008 / Rules and Regulations
effects do not apply. As a result, EPA
has not used a MOE approach to assess
the safety of ammonium salts of fatty
acids (C8–C18 saturated; C8–C12
unsaturated).
VII. Other Considerations
A. Endocrine Disruptors
EPA is required under the FFDCA, as
amended by FQPA, to develop a
screening program to determine whether
certain substances (including all
pesticide active and other ingredients)
‘‘may have an effect in humans that is
similar to an effect produced by a
naturally-occurring estrogen, or other
such endocrine effects as the
Administrator may designate’’.
Ammonium salts of fatty acids (C8–C18
saturated; C8–C12 unsaturated) are not
known endocrine disruptors nor are
they related to any class of known
endocrine disruptors.
B. Analytical Method(s)
There have been no analytical
procedures conducted to ascertain
residuals of ammonium salts of fatty
acids (C8–C18 saturated; C8–C12
unsaturated) on food crops that have
been exposed to pesticides containing
such ammonium salts of fatty acids.
Naturally occurring fatty acids
constitute a significant part of the
normal daily diet and are of low toxicity
when taken orally and pose no known
health risks. Further, based on data and/
or information already reviewed by the
Agency in support of the reregistration
of soap salts of fatty acids, the residues
of these salts of fatty acids from
pesticide use are not likely to exceed
and are likely to be indistinguishable
from levels of naturally occurring fatty
acids in commonly eaten foods.
dwashington3 on PRODPC61 with RULES
C. Codex Maximum Residue Level
There are currently no established
Codex, Canadian, or Mexican MRLs for
ammonium salts of fatty acids in/on
plants or livestock commodities.
Therefore, no compatibility issues exist
with regard to the proposed U.S.
exemption from the requirement of a
tolerance.
VIII. Conclusions
There is currently no tolerance or
tolerance exemption for ammonium
salts of fatty acids. A proposed rule was
published on May 1, 1996 (61 FR 19233)
(FRL–5362–9), to exempt ammonium
oleate and related C8–C18 fatty acids
ammonium salts from the requirement
of a tolerance for residues in or on all
raw agricultural commodities when
used in accordance with good
agricultural practice; however, the
proposed rule was never finalized by
VerDate Aug<31>2005
15:16 Jul 08, 2008
Jkt 214001
the Agency. This action will formalize
food use approval for ammonium salts
of fatty acids as stated in the 1992 RED:
Soap Salts, by exempting ammonium
salts of higher fatty acids from the
requirement of a tolerance.
The Agency has determined that there
is a reasonable certainty that no harm
will result to the U.S. population,
including infants and children from
aggregate exposures to residues of
ammonium salts of fatty acids (C8–C18
saturated; C8–C12 unsaturated). This
conclusion is based on the
demonstrated, very low acute oral and
dermal toxicity of these ammonium
salts and because the Agency anticipates
that actual exposures in food will be
low due to the uses of ammonium soap
salts of fatty acids.
IX. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled Regulatory
Planning and Review (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
Actions Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order
12898, entitled Federal Actions to
Address Environmental Justice in
Minority Populations and Low-Income
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
PO 00000
Frm 00056
Fmt 4700
Sfmt 4700
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) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
X. 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).

Ammonium Soap Salts of Higher Fatty Acids
(C8-C18 saturated; C8-C12)
unsaturated; Exemption from the Requirement of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of the ammonium soap salts of higher fatty
acids (C8-C18 saturated;
C8-C12 unsaturated) in or on all food commodities
when applied for the suppression and control of a wide variety of
grasses and weeds. Falcon Lab, LLC 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 ammonium
soap salts of higher fatty acids (C8-C18
saturated; C8-C12 unsaturated).
DATES: This regulation is effective July 9, 2008. Objections and
requests for hearings must be received on or before September 8, 2008,
and must be filed in accordance with the instructions provided in 40
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings
In the Federal Register of August 8, 2007 (72 FR 44521) (FRL-8139-
7), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 7F7186) by Falcon Lab, LLC, 1103 Norbee Drive, Wilmington,
DE 19803. The petition requested that 40 CFR part 180 be amended by
establishing an exemption from the requirement of a tolerance for
residues of ammonium soap salts of higher fatty acids
(C8-C18 saturated and
C8-C12 unsaturated). This notice failed to
include a summary of the petition prepared by the petitioner Falcon
Lab, LLC, nor was a summary of the petition provided in the docket for
this action. Therefore, EPA republished notice of receipt of this
petition in the Federal Register of April 16, 2008 (73 FR 20631) (FRL-
8360-1), and posted the summary of the petition in the docket for this
action. There were no comments received in response to the notice of
filing.
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 exemption is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines
``safe'' to mean that ``there is a reasonable certainty that no harm
will result from aggregate exposure to the pesticide chemical residue,
including all anticipated dietary exposures and all other exposures for
which there is reliable information.'' This includes exposure through
drinking water and in residential settings, but does not include
occupational exposure. Pursuant to section 408(c)(2)(B) of FFDCA, in
establishing or maintaining in effect an exemption from the requirement
of a tolerance, EPA must take into account the factors set forth in
section 408(b)(2)(C) of FFDCA, which require 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....
'' Additionally, section 408(b)(2)(D) of FFDCA requires that 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 performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First,
[[Page 39266]]
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. Toxicological Profile
Consistent with section 408(b)(2)(D) of 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.
Ammonium soap salts of fatty acids are one class of salts of fatty
acids. Soaps are mineral salts of naturally occurring fatty acids. The
fatty acids are a significant part of the normal daily diet, for they
occur in dietary lipids which usually constitute about 90 grams in a
day's diet. As discussed in this Unit, as part of the reregistration
process, the Agency has already conducted a risk assessment for soap
salts of fatty acids for their potential effects to human health and
the environment and determined that all registered pesticide products
containing the active ingredient Soap Salts are not likely to cause
unreasonable adverse effects in people or the environment and were
eligible for reregistration.
The Agency issued a Reregistration Eligibility Document (RED) in
September 1992 for potassium salts of fatty acids
(C12-C18 saturated and C18
unsaturated, including potassium laureate, potassium myristate,
potassium oleate, and potassium ricinoleate (CAS No. 10124-65-9) and
ammonium salts of fatty acids (C8-C18 saturated
and C18 unsaturated, including ammonium oleate (CAS No.
84776-33-0). While the RED does not specifically identify the active
ingredient ammonium nonanoate (also called pelargonic acid) by name,
the Agency believes the conclusions of the RED are applicable to
ammonium nonanoate because the RED defines the soap salts of fatty
acids that were assessed to be (C8-C18) and
ammonium nonanoate (pelargonic acid) is an ammonium salt of
C9 fatty acid. All soap salts with fatty acids having
aliphatic carbon chains lengths in the range between C8 and
C18 saturated and C8-C12 unsaturated
are virtually identical in regard to chemistry and toxicology.
In support of the RED, the Agency conducted a risk assessment for
soap salts for their potential effects (if any) to human health. The
Agency determined that soap salts of fatty acids are metabolized,
forming simple compounds that serve as energy sources and structural
compounds used in all living cells, and have low acute toxicity by the
oral route of exposure. The RED notes that soap salts of potassium
salts of coco fatty acid and sodium salts of caprylic acid, when
administered to lab animals at high doses cause reproductive and
mutagenic effects. However, based on the low toxicity of ammonium
nonanoate and data/information reviewed in support of the tolerance
exemption for pelargonic acid (ammonium nonanoate acid) which
demonstrated that pelargonic acid did not cause developmental or
mutagenic effects, the Agency believes that there would likely not be
any reproductive or mutagenic effects for this active ingredient when
used in the manner as described in this rule. Further the pesticidal
concentration of ammonium nonanoate will be exceedingly lower in
comparison to those high doses which were administered in the studies
using potassium salts of coco fatty acids.
The active ingredient ammonium soap salts of fatty acids, is used
as a contact, non-selective, broad spectrum, foliar-applied herbicides.
This active ingredient was federally registered in 2006 as a non-food
use pesticide for the suppression and control of a wide variety of
undesirable grasses and weeds. In addition, ammonium salts of fatty
acids have been registered for other non-food uses, including repelling
rabbits and deer from forage and grain crops, vegetables and field
crops, in orchards, and on nursery stock, ornamentals, flower, lawns,
turfs, vines, shrubs and trees.
As part of this rulemaking, EPA reviewed the Soap Salts of Fatty
Acid RED, the Pelargonic Acid Tolerance Exemption (40 CFR 180.1159),
the data and/or information submitted by the petitioner and has
concluded that ammonium nonanoate, a C9 ammonium salt fatty
acid (also called pelargonic acid) and other ammonium soap salts of
higher fatty acids (C8-C18 saturated;
C8-C12 unsaturated) do not pose an unreasonable
adverse effect to the environment, when used in accordance with
approved labeling. While this pesticide is not intended to be sprayed
directly on food or feed crops, the Agency has determined that there
may be a potential for exposure from residues of ammonium soap salts on
food and feed as a result of unintentional spray or drift.
In lieu of submitting new Tier I toxicity studies for ammonium
nonanoate, the registrant relied on data previously submitted in
support of the Soap Salts Registration Eligibility Document (RED). The
RED concluded that fatty acids such as oleic acids and related
C12-C18 fatty acids are generally considered to
be low toxicity by the oral route of exposure and gives a category IV
for both oral and dermal route of exposure. This conclusion can be
extended to all ammonium salts of fatty acids
(C8-C18 saturated; C8-C12
unsaturated) because of the virtual identical chemistry and toxicology
of these fatty acids.
In addition to relying on the RED, the petitioner submitted
requests for waiver of additional studies in support of its petition
for a tolerance exemption.
1. Acute inhalation toxicity: Ammonium salts of fatty acids do not
form aerosol particulates, have a vapor pressure near that of water and
do not readily vaporize. ``In a study in which 10 rats were exposed for
8 hours to saturated vapors of mixed isomers of decanoic acid
(C10) no deaths were observed.'' MRID 43843503 reported that
the LC50 was > 1.244 milligrams/liter (mg/L) for nonanoic
acid (C9).
2. Subchronic oral toxicity: MRID 43843507 reported that no
significant effects were demonstrated in a 14-day range finding study
in rats given nonanoic acid at doses up to 1,834 mg/kilogram (kg)/day.
``The agency concluded that a 90-day oral toxicity study was not
necessary for a dietary risk assessment'' of nonanoic acid due to the
following:
i. Lack of effects at extremely high doses in the range finding
study;
ii. Nature of nonanoic acid (a fatty acid) and its ubiquity in
nature;
iii. The results from acute mammalian toxicology studies; and
iv. The unlikelihood of prolonged human exposure via the oral route
due to the proposed use patterns.
Dietary exposure would be minimized via plant metabolism of
ammonium nonanoic acid through oxidative pathways common for fatty
acids. The same rationale can be applied to ammonium salts of fatty
acids because they share a chemical identity with ammonium nonanoic
acid.
3. Teratogenicity: MRID 43843508, a developmental toxicity study of
nonanoic acid (C9 fatty acid), reported that the treatment
had no adverse effects on clinical signs, body weight, or food/water
consumption. No fetal toxicity was observed. The mean number of viable
fetuses, early or late resorptions, implantation sites, corpora lutea,
pre- and post-implantation losses, sex ratios and fetal body weight
were comparable to those of the control group. The no observed adverse
effect level (NOAEL)
[[Page 39267]]
for maternal and developmental toxicity was 1,500 mg/kg/day and the
lowest observed adverse effect level (LOAEL) was > 1,500 mg/kg/day. The
developmental toxicity study for ammonium nonanoic acid showed no
effects at dose levels above the limit dose (1,000 mg/kg/day).
Therefore, the tier 1 data requirement for food use for this
biochemical pesticide is satisfied. The same rationale can be applied
to ammonium salts of fatty acids because they share a chemical identity
with ammonium nonanoic acid.
4. Immune response: This study is conditionally required when there
is a requirement for a sub-chronic oral, dermal, or inhalation study,
depending on the most likely routes of exposure. The registrant
requested waivers based on the factors given for the waiver request of
the 90-day oral toxicity study.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of FFDCA directs EPA
to consider available information concerning exposures from the
pesticide 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).
Aggregate exposure to ammonium salts may occur via oral and dermal
routes. Since the acute oral toxicity of soap salts is low (Toxicity
Category IV), the risks anticipated from oral exposures are considered
minimal. The acute dermal toxicity is also low (Toxicity Category IV).
Longer dermal exposures can produce mild to moderate irritation, but
soap salts are not skin sensitizers. As a result, the anticipated risks
from dermal exposure are considered minimal. Since the inhalation route
is not a likely exposure pathway the anticipated risk from inhalation
exposure are also considered minimal.
A. Dietary Exposure
1. Food. Pesticides containing ammonium soap salts of fatty acids
are likely to be used as contact, non-selective, broad spectrum,
foliar-applied herbicides or as repellents. As such they are likely not
to be applied directly to any food plants. Moreover, ammonium salts of
fatty acids are expected to be rapidly metabolized by soil
microorganisms, with a half-life of perhaps less than one day,
therefore residues of ammonium salts of fatty acids when used in
accordance with approved labeling will not persist in the environment.
The lack of direct application to food plants coupled with the rapid
metabolization of ammonium salts when used as pesticides will result in
low exposures to ammonium soap salts of fatty acids. However, if the
exposures to ammonium soap salts to humans from food commodities that
have been indirectly sprayed with residues of ammonium salts occur, the
Agency does not expect exposures to be unsafe due the low acute
toxicity and likely low exposure of these soap salts.
2. Drinking water exposure. No significant exposure to drinking
water is expected from an accumulation of soap salts in the aquatic
environment when it is used in accordance with approved labeling.
Ammonium salts of fatty acids are not to be applied directly to water.
B. Other Non-Occupational Exposure
Non-occupational dermal exposure to ammonium salts of fatty acids
will be expected since the use of this pesticide will be in the
residential settings. However, the Agency believes that any hazard
related to exposure to residential users from this pesticide will
likely be insignificant. This belief is based on the fact that the
toxicity data demonstrated no toxic endpoints upon which to base a risk
characterization at or below 1,000 mg/kg of body weight/day (the limit
dose).
Non-occupational inhalation exposure is not expected because
ammonium salts of fatty acids do not form aerosol particulates, have a
vapor pressure near that of water, and do not readily vaporize.
V. Cumulative Effects
Section 408(b)(2)(D)(v) of the FFDCA requires the Agency to
consider the cumulative effect of exposure to residues that have a
common mechanism of toxicity. These considerations include the possible
cumulative effects of such residues on infants and children. Except for
ocular exposure, ammonium nonanoate is of low toxicity, and it is not
anticipated that there would be cumulative effects from common
mechanisms of toxicity.
Studies of fatty acids and fatty acid salts previously submitted to
the Agency, indicate that the half-life of fatty acids is less than one
(1) day (MRID 00157476). As can be expected, there is very rapid
microbial degradation of fatty acids in soil. Fatty acids and their
salts are excellent substrates for microbial growth, serving both as
carbon sources and energy sources. The active ingredient cannot totally
dissipate from soil, because there is a natural content of fatty acids
in soil resulting from plant metabolism and by formation of microbial
organisms. Fatty acids constitute a significant portion of the normal
daily diet of mammals (including humans, birds, and invertebrates since
they are found in large amounts in the form of lipids in all living
tissues (including seeds). Microbial metabolism of fatty acids has the
effect of either converting the degradates to CO2 and ester
(if used as an energy source) or converting the carbon content of the
fatty acid to any of the thousands of naturally occurring organic
substances produced by the soil microflora (if used as a carbon
source). Based on these known facts of the role of fatty acids in the
environment and in food and feed, there should be no concern for
cumulative effects of ammonium salts of fatty acids used as pesticides.
VI. Determination of Safety for U.S. Population, Infants and Children
There is a reasonable certainty that no harm to the U.S.
population, including infants and children , will result from aggregate
exposure to residues of ammonium salts of fatty acids
(C8-C18 saturated; C8-C12
unsaturated) due to their use as a pesticide. This includes all
anticipated dietary exposures and all other exposures for which there
is reliable information. As discussed in Unit III, ammonium salts of
fatty acids (C8-C18 saturated;
C8-C12 unsaturated) have low toxicity. Moreover,
many soap salts of fatty acids are part of the human diet and pesticide
exposures are not expected to exceed the levels of naturally occurring
fatty acids in commonly eaten foods. Accordingly, exempting ammonium
salts of fatty acids (C8-C18 saturated;
C8-C12 unsaturated) from the requirement of a
tolerance is considered safe.
FFDCA section 408 provides that EPA shall apply an additional
tenfold margin of exposure MOE (safety) for infants and children in the
case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the data base unless EPA determines
that a different margin of exposure (safety) will be safe for infants
and children. Margins of exposure are often referred to as uncertainty
or safety factors. In this instance, based on all available
information, the Agency concludes that ammonium salts of fatty acids
are practically non-toxic to mammals including infants and children.
Because there are no threshold effects of concern to infants, children,
and adults when ammonium salt is used as labeled, the provision
requiring an additional margin of safety does not apply. Further, the
provisions of consumption patterns, special susceptibility, and
cumulative
[[Page 39268]]
effects do not apply. As a result, EPA has not used a MOE approach to
assess the safety of ammonium salts of fatty acids
(C8-C18 saturated; C8-C12
unsaturated).
VII. Other Considerations
A. Endocrine Disruptors
EPA is required under the FFDCA, as amended by FQPA, to develop a
screening program to determine whether certain substances (including
all pesticide active and other ingredients) ``may have an effect in
humans that is similar to an effect produced by a naturally-occurring
estrogen, or other such endocrine effects as the Administrator may
designate''. Ammonium salts of fatty acids
(C8-C18 saturated; C8-C12
unsaturated) are not known endocrine disruptors nor are they related to
any class of known endocrine disruptors.
B. Analytical Method(s)
There have been no analytical procedures conducted to ascertain
residuals of ammonium salts of fatty acids
(C8-C18 saturated; C8-C12
unsaturated) on food crops that have been exposed to pesticides
containing such ammonium salts of fatty acids. Naturally occurring
fatty acids constitute a significant part of the normal daily diet and
are of low toxicity when taken orally and pose no known health risks.
Further, based on data and/or information already reviewed by the
Agency in support of the reregistration of soap salts of fatty acids,
the residues of these salts of fatty acids from pesticide use are not
likely to exceed and are likely to be indistinguishable from levels of
naturally occurring fatty acids in commonly eaten foods.
C. Codex Maximum Residue Level
There are currently no established Codex, Canadian, or Mexican MRLs
for ammonium salts of fatty acids in/on plants or livestock
commodities. Therefore, no compatibility issues exist with regard to
the proposed U.S. exemption from the requirement of a tolerance.
VIII. Conclusions
There is currently no tolerance or tolerance exemption for ammonium
salts of fatty acids. A proposed rule was published on May 1, 1996 (61
FR 19233) (FRL-5362-9), to exempt ammonium oleate and related
C8-C18 fatty acids ammonium salts from the
requirement of a tolerance for residues in or on all raw agricultural
commodities when used in accordance with good agricultural practice;
however, the proposed rule was never finalized by the Agency. This
action will formalize food use approval for ammonium salts of fatty
acids as stated in the 1992 RED: Soap Salts, by exempting ammonium
salts of higher fatty acids from the requirement of a tolerance.
The Agency has determined that there is a reasonable certainty that
no harm will result to the U.S. population, including infants and
children from aggregate exposures to residues of ammonium salts of
fatty acids (C8-C18 saturated;
C8-C12 unsaturated). This conclusion is based on
the demonstrated, very low acute oral and dermal toxicity of these
ammonium salts and because the Agency anticipates that actual exposures
in food will be low due to the uses of ammonium soap salts of fatty
acids.
IX. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, Actions Concerning Regulations
That Significantly Affect Energy Supply, Distribution, or Use (66 FR
28355, May 22, 2001) or Executive Order 13045, entitled Protection of
Children from Environmental Health Risks and Safety Risks (62 FR 19885,
April 23, 1997). This final rule does not contain any information
collections subject to OMB approval under the Paperwork Reduction Act
(PRA), 44 U.S.C. 3501 et seq., nor does it require any special
considerations under Executive Order 12898, entitled Federal Actions to
Address Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
X. 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).
