[EPA-HQ-OPP-2008-0652; FRL-8809-6]

 
Ammonium Salts of Fatty Acids (C8-C18 
Saturated); 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 ammonium salts of fatty acids 
(C8-C18 saturated) applied pre- and post-harvest 
on all raw agricultural commodities when applied/used as a surfactant. 
Falcon Lab, LLC. submitted a petition to EPA under the Federal Food, 
Drug, and Cosmetic Act (FFDCA), requesting an exemption from the 
requirement of a tolerance. This regulation eliminates the need to 
establish a maximum permissible level for residues of ammonium salts of 
fatty acids (C8-C18 saturated).

DATES: This regulation is effective March 24, 2010. Objections and 
requests for hearings must be received on or before May 24, 2010, 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 September 5, 2008 (73 FR 51817) (FRL-
8380-4), EPA issued a notice pursuant to section 408 of FFDCA, 21 
U.S.C. 346a, as amended by the Food Quality Protection ACT (FQPA) 
(Public Law 104-170), announcing the filing of a pesticide petition (PP 
8E7402) by Falcon Lab, LLC, 1103 Norbee Drive, Wilmington, DE 19803. 
The petition requested that 40 CFR 180.910 be amended by establishing 
an exemption from the requirement of a tolerance for residues of 
ammonium salts of fatty acids (C8-C18 saturated) 
when used as an inert ingredient in pesticide formulations applied pre- 
and post-harvest. A request for a tolerance exemption under 40 CFR 
180.950 was withdrawn by the company. That notice included a summary of 
the petition prepared by the petitioner. There were no comments 
received in response to the notice of filing.
    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish an 
exemption from the requirement for a tolerance (the legal limit for a 
pesticide chemical residue in or on a food) only if EPA determines that 
the tolerance is ``safe.'' Section 408(b)(2)(A)(ii) of FFDCA defines 
``safe'' to mean that ``there is a reasonable certainty that no harm 
will result from aggregate exposure to the pesticide chemical residue, 
including all anticipated dietary exposures and all other exposures for 
which there is reliable information.'' This includes exposure through 
drinking water and in residential settings, but does not include 
occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to 
give special consideration to exposure of infants and children to the 
pesticide chemical residue in establishing a tolerance and to ``ensure 
that there is a reasonable certainty that no harm will result to 
infants and children from aggregate exposure to the pesticide chemical 
residue. . . .''
    EPA 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 ingredients (except when they have a 
pesticidal efficacy of their own): Solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene ploymers 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 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 
ammonium salts of fatty acids (C8-C18 saturated) 
are discussed in this unit. The following provides a brief summary of 
the risk assessment and conclusions for the Agency's review of ammonium 
salts of fatty acids (C8-C18 saturated). The 
Agency's full decision document for this action is available in the 
Agency's electronic docket (regulations.gov) under the docket ID number 
EPA-HQ-OPP-2008-0652.

[[Page 14084]]

    Ammonium salts of fatty acids are mineral salts of naturally 
occurring fatty acids found in the environment. Fatty acids play a 
significant role in the normal diet of humans, animals, and plants and 
currently have Food and Drug Administration and EPA approved uses in 
food products. They are naturally present in commonly eaten fats and 
oils, accounting for approximately 30 to 40% of the caloric intake in 
the U.S. diet (~ 90 grams/day). They are also found in cosmetics and 
household cleaning products.
    Ammonium salts of fatty acids have shown to be of low toxicity via 
the oral and dermal routes of exposure, Toxicity category IV and III, 
respectively (40 CFR 156.62). When applied for long periods of time, 
they have the potential to be dermal irritants. In addition, ammonium 
salts of fatty acids are eye irritants and have the potential to cause 
permanent eye injury. Limited data are available regarding the 
inhalation toxicity of soap salts; however, they are anticipated to be 
irritating via the inhalation route of exposure.
    A subchronic range finding study did not see any significant 
systemic toxicity from nonanoic acid (C9 saturated) given to 
rats at doses up to 1,834 milligrams/kilograms/day (mg/kg/day). 
Ammonium salts of fatty acids are not believed to be mutagenic or 
carcinogenic. When used at very high doses, potassium salts of fatty 
acids (a chemical belonging to the same chemical group) caused 
reproductive effects (post-implantation mortality at 6,000 mg/kg/day (6 
times the limit dose of 1,000 mg/kg/day) on days 2 to 13 of pregnancy 
and musculo-skeletal abnormalities observed at 600 mg/kg/day); however, 
studies on ammonium salts of fatty acids did not show developmental or 
mutagenic effects in rats at doses up to 1,500 mg/kg/day. In addition, 
no signs of neurotoxicity or carcinogencity were observed. Although 
reproductive/developmental effects were seen at very high doses in a 
study on a structurally similar chemical, these effects were not 
observed in studies on the actual inert ingredient at doses up to 1,500 
mg/kg/day. Based on the available evidence the Agency does not believe 
that ammonium salt of fatty acids (C8-C18 
saturated) when used as an inert ingredient in pesticide products will 
cause reproductive or developmental effects. Due to the low toxicity of 
ammonium soap salts and the natural occurrence of fatty acids in the 
environment and food products, a chronic study was not required.

V. 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).
    EPA establishes exemptions from the requirement of a tolerance only 
in those cases where it can be clearly demonstrated that the risks from 
aggregate exposure to pesticide chemical residues under reasonably 
foreseeable circumstances will pose no appreciable risks to human 
health. In order to determine the risks from aggregate exposure to 
pesticide inert ingredients, the Agency considers the toxicity of the 
inert in conjunction with possible exposure to residues of the inert 
ingredient through food, drinking water, and through other exposures 
that occur as a result of pesticide use in residential settings. If EPA 
is able to determine that a finite tolerance is not necessary to ensure 
that there is a reasonable certainty that no harm will result from 
aggregate exposure to the inert ingredient, an exemption from the 
requirement of a tolerance may be established.
    Fatty acids are an essential component of the mammalian diet and 
the body is able to metabolize these soap salts and use them as an 
energy source. Due to the self-limiting nature of these chemicals (e.g. 
unpleasant taste and odor, herbicidal properties), their natural 
occurrence in the environment, their rapid environmental degradation 
and low toxicity, and their presence in commonly eaten foods (both 
naturally and intentionally added), a quantitative exposure assessment 
was not performed. The anticipated exposure from the use of ammonium 
salts of fatty acids as inert ingredients in pesticide products is 
expected to be minimal and is not anticipated to significantly increase 
the overall exposure to all populations including infants and children.
    Because of their strong soil adsorption and the rapid degradation 
of ammonium salts of fatty acids they are not expected to reach surface 
water via runoff nor are they expected to leach into ground water. 
Based on the physical/chemical properties, volatilization from soils 
and water is not expected. There is no expected translocation into 
plants. Ammonium salts of fatty acid are not likely to persist in the 
environment and are expected to be indistinguishable from naturally 
occurring ammonium ions and fatty acids already present in the 
environment as a result of plant metabolism and formation by soil 
microbes.

VI. Cumulative Effects

    Section 408(b)(2)(D)(v) of FFDCA requires that, when considering 
whether to establish, modify, or revoke a tolerance, the Agency 
consider ``available information'' concerning the cumulative effects of 
a particular pesticide's residues and ``other substances that have a 
common mechanism of toxicity.''
    Unlike other pesticides 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 ammonium salts of fatty 
acids (C8-C18 saturated) and any other 
substances, and these chemicals 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 these chemicals 
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 concerning common mechanism determinations and 
procedures for cumulating effects from substances found to have a 
common mechanism of toxicity on EPA's website at http://ww.epa.gov/
pesticides/cumulative/.

VII. Additional Safety Factor for the Protection of Infants and 
Children.

    Section 408 of the FFDCA provides that EPA shall apply an 
additional tenfold margin of exposure (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. There was no evidence of systemic toxicity or 
developmental toxicity in rats at doses up to 1,500 mg/kg/day in a 
developmental toxicity study (Master Record Identification Number 
43843508) on pelargonic acid (nonanoate acid). The study showed no 
adverse effect of treatment on clinical signs, body weights, weight 
gain, or food/water consumption. No fetal toxicity attributed to the 
effects of treatment was observed between the

[[Page 14085]]

treated (1,500 mg/kg/day) or the untreated controls. Similarly, no 
systemic toxicity was observed at doses up to and including 1,837 mg/
kg/day in a 14-day toxicity study in rats. No clinical signs of 
neurotoxicity were seen in any of the repeat dose studies. Since there 
was no hazard identified to adults and developing fetuses EPA did not 
use a safety factor analysis in assessing risks to ammonium salts of 
fatty acids (C8-C18 saturated). For similar 
reasons, EPA determined that an additional safety factor to protect 
infants and children is not needed.

VIII. Determination of Safety for U.S. Population

    As noted in Unit IV, ammonium salts of fatty acids are not expected 
to pose an acute risk. Because of the low oral and dermal toxicity, the 
rapid degradation of the chemical, and the natural presence of fatty 
acids in the environment, the Agency concluded that aggregate exposure 
will result in minimal risk to all subpopulations, including infants 
and children. Since the inhalation route is not a likely exposure 
pathway the anticipated risk from inhalation exposure is also 
considered minimal.
    Taking into consideration all available information on ammonium 
salts of fatty acids (C8-C18 saturated), it has 
been determined that there is a reasonable certainty that no harm to 
any population subgroup, including infants and children, will result 
from aggregate exposure to this chemical. Therefore, the exemption from 
the requirement of a tolerance for residues of ammonium salts of fatty 
acids (C8-C18 saturated) (CAS Reg. No. 5972-76-9, 
63718-65-0, 16530-70-4, 32582-95-9, 2437-23-2, 191799-95-8, 16530-71-5, 
93917-76-1, 5297-93-8, 94266-36-1, 1002-89-7), when used as inert 
ingredient in pre- and post-harvest applications, under 40 CFR 180.910 
can be considered safe under section 408(q) of the FFDCA.

IX. Other Considerations

A. Analytical Method

    An analytical method is not required for enforcement purposes since 
the Agency is establishing an exemption from the requirement of a 
tolerance without any numerical limitation.

B. Existing Exemptions

    Ammonium stearate (C18 saturated; CAS Reg. No. 1002-89-
7), one of the soap salts, has been approved as an inert ingredient 
under 40 CFR 180.910. In addition, 40 CFR 180.1284 established an 
exemption from the requirement of a tolerance for residues of the 
active ingredient ammonium 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.

C. International Tolerances

    The Agency is not aware of any country requiring a tolerance for 
ammonium salts of fatty acids (C8-C18 saturated) 
nor have any CODEX Maximum Residue Levels (MRLs) been established for 
any food crops at this time.

X. Conclusions

    Therefore, a tolerance exemption is established for Ammonium salts 
of fatty acids (C8-C18 saturated) (CAS Reg. No. 
5972-76-9, 63718-65-0, 16530-70-4, 32582-95-9, 2437-23-2, 191799-95-8, 
16530-71-5, 93917-76-1, 5297-93-8, 94266-36-1, 1002-89-7) when used as 
inert ingredient in pesticide formulations applied to pre- and post-
harvest crops only.

XI. Statutory and Executive Order Reviews

    This final rule establishes a tolerance under section 408(d) of 
FFDCA in response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993). Because this final rule has been 
exempted from review under Executive Order 12866, this final rule is 
not subject to Executive Order 13211, entitled Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
Protection of Children from Environmental Health Risks and Safety Risks 
(62 FR 19885, April 23, 1997). This final rule does not contain any 
information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any 
special considerations under Executive Order 12898, entitled Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under section 408(d) of FFDCA, such as the 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.
    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).

XII. 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).
