9-Octadecenoic Acid (9Z)-, Sulfonated,
Oxidized and its Potassium and
Sodium Salts; Exemption From the
Requirement of a Tolerance
Environmental Protection
Agency (EPA).
ACTION: Final rule.
AGENCY:
This regulation establishes an
exemption from the requirement of a
tolerance for residues of 9-octadecenoic
acid (9Z)-, sulfonated, oxidized; 9octadecenoic acid (9Z)-, sulfonated,
oxidized, potassium salts; and 9octadecenoic acid (9Z)-, sulfonated,
oxidized, sodium salts, when used as an
inert ingredient in antimicrobial
pesticide formulations used on food
contact surfaces in public eating places,
dairy processing equipment and food
processing equipment and utensils at a
maximum end-use concentration not to
exceed 250 parts per million (ppm).
Ecolab submitted a petition to EPA
under the Federal Food, Drug, and
Cosmetic Act (FFDCA), requesting
establishment of an exemption from the
requirement of a tolerance. This
regulation eliminates the need to
establish a maximum permissible level
for residues of 9-octadecenoic acid
(9Z)-, sulfonated, oxidized and its
potassium and sodium salts.
DATES: This regulation is effective
March 4, 2015. Objections and requests
for hearings must be received on or

III. Inert Ingredient Definition
Inert ingredients are all ingredients
that are not active ingredients as defined
in 40 CFR 153.125 and include, but are
not limited to, the following types of
ingredients (except when they have a
pesticidal efficacy of their own):
Solvents such as alcohols and
hydrocarbons; surfactants such as
polyoxyethylene polymers and fatty
acids; carriers such as clay and
diatomaceous earth; thickeners such as
carrageenan and modified cellulose;
wetting, spreading, and dispersing
agents; propellants in aerosol
dispensers; microencapsulating agents;
and emulsifiers. The term ‘‘inert’’ is not
intended to imply nontoxicity; the
ingredient may or may not be
chemically active. Generally, EPA has
exempted inert ingredients from the
requirement of a tolerance based on the
low toxicity of the individual inert
ingredients.
IV. Aggregate Risk Assessment and
Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be clearly
demonstrated that the risks from
aggregate exposure to pesticide
chemical residues under reasonably
foreseeable circumstances will pose no
appreciable risks to human health. In
order to determine the risks from
aggregate exposure to pesticide inert
ingredients, the Agency considers the
toxicity of the inert in conjunction with
possible exposure to residues of the
VerDate Sep<11>2014
22:23 Mar 03, 2015
Jkt 235001
inert ingredient through food, drinking
water, and through other exposures that
occur as a result of pesticide use in
residential settings. If EPA is able to
determine that a finite tolerance is not
necessary to ensure that there is a
reasonable certainty that no harm will
result from aggregate exposure to the
inert ingredient, an exemption from the
requirement of a tolerance may be
established.
Consistent with FFDCA section
408(c)(2)(A), and the factors specified in
FFDCA section 408(c)(2)(B), EPA has
reviewed the available scientific data
and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure for 9-octadecenoic
acid (9Z)-, sulfonated, oxidized and its
potassium and sodium salts including
exposure resulting from the exemption
established by this action. EPA’s
assessment of exposures and risks
associated with 9-octadecenoic acid
(9Z)-, sulfonated, oxidized and its
potassium and sodium salts follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered their
validity, completeness, and reliability as
well as the relationship of the results of
the studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children. Specific
information on the studies received and
the nature of the adverse effects caused
by 9-octadecenoic acid (9Z)-, sulfonated,
oxidized and its potassium and sodium
salt (also referred to as peroxy
sulfonated oleic acid (PSOA)) as well as
the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies discussed in this unit.
Peroxy sulfonated oleic acid is acutely
toxic via the oral route and is highly
corrosive via the dermal and inhalation
routes of exposure. In a 28-day oral
toxicity study (OECD Guideline 407),
rats were administered PSOA via gavage
at dose levels of 15 milligrams/
kilogram/day (mg/kg/day) and 50 mg/
kg/day. No observable adverse effects
were seen at either dose level but since
no systemic effects were observed, the
dosing was considered by the Agency to
not be adequate.
In a developmental toxicity (OECD
Guideline 414) study with PSOA, the
parental NOAEL for systemic effects
was 50 mg/kg bw/day, the highest dose
tested. The NOAEL for embryotoxic,
fetotoxic and developmental effects was
PO 00000
Frm 00056
Fmt 4700
Sfmt 4700
also 50 mg/kg bw/day, the highest dose
tested.
The dosing in the 28-day gavage study
and the developmental toxicity studies
was considered inadequate because
animals were not challenged at higher
doses. The applicant suggested that the
higher doses were not utilized because
of the corrosive nature of the chemical.
Since there was no evidence of
corrosivity in the study, a 14-day oral
toxicity study was conducted at dose
levels of 100 mg/kg/day, 300 mg/kg/day
and 1,000 mg/kg/day. The study results
confirmed that higher doses would have
been corrosive.
In a series of genotoxicity studies
PSOA is negative for inducing
mutations in bacterial and mammalian
cells, with and without metabolic
activation. In the in vitro chromosome
aberration study using human
lymphocytes, PSOA was positive with
and without metabolic activation.
However, the in vivo micronucleus
assay in rats was negative.
A neurotoxicity study was not
conducted with PSOA. However,
detailed functional observations were
made among the parameters measured
in the 28-day subchronic oral feeding
study. There were no PSOA related
changes in any of the parameters
measured, including functional
observations battery (FOB). No evidence
of neurotoxicity was observed. An
immunotoxicity study was not
conducted with PSOA. However,
minimal hemorrhage in the thymus was
observed after the recovery period in the
14-day oral toxicity study with rats.
Since, this effect is a common
background lesion it is not considered
indicative of potential immunotoxicity.
There are no known chronic toxicity
studies with PSOA and no available
PSOA mammalian metabolism studies.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
E:\FR\FM\04MRR1.SGM
04MRR1
Federal Register / Vol. 80, No. 42 / Wednesday, March 4, 2015 / Rules and Regulations
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to PSOA, EPA considered
exposure under the proposed exemption
from the requirement of a tolerance.
EPA assessed dietary exposures from
peroxy sulfonated oleic acids in food as
follows:
In the absence of actual dietary
exposure data resulting from this use,
EPA has utilized a conservative, healthprotective method of estimating dietary
intake that is based upon conservative
assumptions related to the amount of
residues that can be transferred to foods
as a result of the proposed use of 9octadecenoic acid (9Z)-, sulfonated,
oxidized and its potassium and sodium
salts in food contact sanitizing pesticide
products. This same methodology has
been utilized by EPA in estimating
dietary exposures to antimicrobial
pesticides used in food-handling
settings. A complete description of the
approach used to assess dietary
exposures resulting from food contact
sanitizing solution uses of nitric acid
can be found at https://
www.regulations.gov in document
‘‘Peroxy Sulfonated Oleic Acids; Human
Health Risk Assessment and Ecological
Effects Assessment to Support Proposed
Exemption from the Requirement of a
Tolerance When Used as Inert
Ingredients in Pesticide Formulations,’’
pp. 14–15 in docket ID number EPA–
HQ–OPP–2013–0601. EPA assessed
dietary exposures from 9-octadecenoic
acid (9Z)-, sulfonated, oxidized and its
potassium and sodium salts in food as
follows:
VerDate Sep<11>2014
22:23 Mar 03, 2015
Jkt 235001
i. Acute exposure. No adverse effects
attributable to a single exposure of
PSOA were seen in the toxicity
databases. Therefore, an acute dietary
exposure assessment for 9-octadecenoic
acid (9Z)-, sulfonated, oxidized and its
potassium and sodium salts is not
necessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure
assessment, the Agency believes the
assumptions used to estimate chronic
dietary exposures lead to an extremely
conservative assessment of chronic
dietary risk due to a series of
compounded conservative assumptions.
First, when a surface is treated with a
disinfectant, a quantity of the
disinfectant remains on the surface
(residual solution). In the absence of any
other data, EPA has used an estimated
worst-case concentration of 1 mg of
residual solution per square centimeter
(cm) of treated surface area for this
quantity. Second, the conservatism of
this methodology is compounded by
EPA’s decision to assume a worst case
scenario that all food that an individual
consumers will come into contact with
4,000 cm2 of sanitized non-porous food
contact surfaces. This contact area
represents all the surface area from
silverware, china, and glass used by a
person who regularly eats three meals
per day at an institutional or public
facility. Third, EPA assumes that 100%
of the material present on food contact
surfaces will migrate to food.
2. Dietary exposure from drinking
water. Due to the proposed use pattern,
the Agency believes PSOA will not
enter surface water or ground water as
PO 00000
Frm 00057
Fmt 4700
Sfmt 4700
a result of the proposed use. Therefore
a dietary exposure assessment for
drinking water is not necessary.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure.
Peroxy sulfonated oleic acids are not
used as an inert ingredient in pesticide
products that are registered for specific
uses that may result in both indoor and
outdoor residential exposures.
Therefore, a residential exposure and
risk assessment was not conducted for
PSOA.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found peroxy sulfonated
oleic acids to share a common
mechanism of toxicity with any other
substances, and peroxy sulfonated oleic
acids do not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that peroxy sulfonated oleic
acids do not have a common mechanism
of toxicity with other substances. For
information regarding EPA’s efforts to
determine which chemicals have a
common mechanism of toxicity and to
evaluate the cumulative effects of such

chemicals, see EPA’s Web site at https://
www.epa.gov/pesticides/cumulative.
assessment will not underestimate the
exposure and risks posed by PSOA.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no concern for fetal
susceptibility. There were no treatment
related effects observed in a
developmental toxicity study in rats up
to the maximum dose tested (50 mg/kg/
day). Based on the corrosive nature of
PSOA toxicity testing at doses greater
than 100 mg/kg/day results in local
effects (i.e., severe gastrointestinal
irritation) with other observed systemic
effects being secondary to the irritation
effects. Therefore, based on the available
data, there are no concerns for residual
uncertainties concerning prenatal and
postnatal toxicity.
3. Conclusion. EPA has determined
that reliable data show the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1X. That decision is
based on the following findings:
i. The NOAEL used for risk
assessment is based on the corrosive
effects of PSOA which occur at dose
levels below which any systemic
toxicity is observed and is therefore
protective of potential developmental
and reproductive effects.
ii. There is no indication that PSOA
is a neurotoxic chemical and there is no
need for a developmental neurotoxicity
study or additional UFs to account for
neurotoxicity.
iii. There is no indication that PSOA
is an immunotoxic chemical and there
is no need for additional UFs to account
for immunotoxicity.
iv. There is no evidence that PSOA
results in increased susceptibility in in
utero rodents.
v. There are no residual uncertainties
identified in the exposure databases.
EPA made conservative (healthprotective) assumptions regarding
dietary exposure to PSOA. This
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic pesticide exposures are safe by
comparing aggregate exposure estimates
to the acute PAD (aPAD) and chronic
PAD (cPAD). The aPAD and cPAD
represent the highest safe exposures,
taking into account all appropriate SFs.
EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs.
For linear cancer risks, EPA calculates
the probability of additional cancer
cases given the estimated aggregate
exposure. Short-, intermediate-, and
chronic-term risks are evaluated by
comparing the estimated aggregate food,
water, and residential exposure to the
POD to ensure that the MOE called for
by the product of all applicable UFs is
not exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, peroxy sulfonated
oleic acids are not expected to pose an
acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to peroxy
sulfonated oleic acids from food and
water will utilize 18% of the cPAD for
children 1–2 years old, the population
group receiving the highest exposure.
There are no residential uses for peroxy
sulfonated oleic acids. Based on the
explanation in Unit IIIC.3 residential
use patterns, chronic residential
exposure to residues of peroxy
sulfonated oleic acids is not expected.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water
(considered to be a background
exposure level). Because there are no
residential uses, short-term residential
exposures are not likely to occur, and no
short-term adverse effect was identified
therefore peroxy sulfonated oleic acids
are not expected to pose a short-term
aggregate risk.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Because there are no residential uses,
intermediate-term residential exposures
are not likely to occur, and peroxy

Sfmt 4700
sulfonated oleic acids are not expected
to pose an intermediate-term aggregate
risk.
5. Aggregate cancer risk for U.S.
population. Based upon negative
response for mutagenicity in a battery of
genotoxicity tests, and lack of any
structural alerts for carcinogenicity,
peroxy sulfonated oleic acids are not
expected to pose a cancer risk to
humans.
6. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to peroxy
sulfonated oleic acids residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is not establishing a numerical
tolerance for residues of peroxy
sulfonated oleic acids of in or on any
food commodities. EPA is establishing a
limitation on the amount of peroxy
sulfonated oleic acids that may be used
in pesticide formulations. That
limitation will be enforced through the
pesticide registration process under the
Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA), 7 U.S.C. 136
et seq. EPA will not register any
pesticide for sale or distribution for
which the final end use concentration of
peroxy sulfonated oleic acids in
antimicrobial food contact surface
sanitizing solutions would exceed 250
ppm.
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nation Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing

VI. Conclusions
Therefore, an exemption from the
requirement of a tolerance is established
under 40 CFR 180.940(a) for residues of
9-octadecenoic acid (9Z)-, sulfonated,
oxidized (CAS Reg. No. 1315321–93–7);
9-octadecenoic acid (9Z)-, sulfonated,
oxidized, potassium salts (CAS Reg. No.
1315321–94–8); and 9-octadecenoic acid
(9Z)-, sulfonated, oxidized, sodium
salts, (CAS No. 1315321–95–9) when
used as an inert ingredient in
antimicrobial pesticide formulations
used on food contact surfaces in public
eating places, dairy processing
equipment and food processing
equipment and utensils at a maximum
end-use concentration not to exceed 250
ppm.
VII. Statutory and Executive Order
Reviews
This action establishes a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
Tribes. Thus, the Agency has
determined that Executive Order 13132,
entitled ‘‘Federalism’’ (64 FR 43255,
August 10, 1999) and Executive Order
13175, entitled ‘‘Consultation and
Coordination with Indian Tribal
Governments’’ (65 FR 67249, November
9, 2000) do not apply to this action. In
addition, this action does not impose
any enforceable duty or contain any
unfunded mandate as described under
Title II of the Unfunded Mandates
Reform Act (UMRA) (2 U.S.C. 1501 et
seq.).
This action does not involve any
technical standards that would require

Synopsis
As required by the Paperwork
Reduction Act of 1995 (44 U.S.C. 3507),
the FCC is notifying the public that it
received OMB approval on January 29,
2015, for the information collection
requirements contained in 64.2103,
64.2105, and 64.2107 of the
Commission’s Rules and the
information collection in paragraph 67
of the Order.
Under 5 CFR part 1320, an agency
may not conduct or sponsor a collection
of information unless it displays a
current, valid OMB Control Number.
No person shall be subject to any
penalty for failing to comply with a
collection of information subject to the
Paperwork Reduction Act that does not
display a current, valid OMB Control
Number. The OMB Control Number is
3060–1186.
The foregoing notice is required by
the Paperwork Reduction Act of 1995,
Public Law 104–13, October 1, 1995,
and 44 U.S.C. 3507.
The total annual reporting burdens
and costs for the respondents are as
follows:
OMB Control Number: 3060–1186.
OMB Approval Date: January 29,
2015.
OMB Expiration Date: January 31,

offered because this information
collection does not require the
collection of personally identifiable
information from individuals. If the FCC
requests that respondents submit
information which respondents believe
is confidential, respondents may request
confidential treatment of such
information pursuant to Section 0.459 of
the FCC’s rules, 47 CFR 0.459.
Needs and Uses: On October 28, 2013,
the Wireline Competition Bureau
(Bureau) of the Federal Communications
Commission adopted a Report and
Order (Order), in WC Docket No. 13–39;
FCC 13–135, 78 FR 76218, Rural Call
Completion. Under the rules adopted by
the Order, submission of Form 480 is
mandatory for a ‘‘covered provider’’ as
defined in 47 CFR 64.2101(c). A covered
provider failing to file Form 480 in a
timely fashion may be subject to
penalties under the Communications
Act, including sections 502 and 503(b).
In the Order the Commission improves
its ability to monitor problems with
completing calls to rural areas, and
enforce restrictions against blocking,
choking, reducing, or restricting calls.
The Order applies the new rules to
‘‘covered providers,’’ meaning providers
of long-distance voice service that make
the initial long-distance call path choice
for more than 100,000 domestic retail
subscriber lines, counting the total of all
business and residential fixed
subscriber lines and mobile phones and
aggregated over all of the providers’
affiliates. In most cases, this is the
calling party’s long-distance provider.
Covered providers include LECs,
interexchange carriers (IXCs),
commercial mobile radio service
(CMRS) providers, and VoIP service
providers. These rules do not apply to
intermediate providers. Covered
providers must file quarterly reports and
retain the call detail records for at least
six calendar months. Long-distance
voice service providers that have more
than 100,000 domestic retail subscriber
lines but that, for reasons set forth in
paragraph 67 of the Order, are not
required to file quarterly reports are
required to file a one-time letter in WC
Docket No. 13–39 explaining that they
do not make the initial long-distance
call path choice for more than 100,000
long-distance voice service subscriber
lines and identifying the long-distance
provider or providers to which they
hand off their end-user customers’ calls.
The Order also allows qualifying
providers to certify that they meet the
conditions for a Safe Harbor that would
reduce reporting and retention
obligations. In addition, the
Commission has delegated to the

9-Octadecenoic Acid (9Z)-, Sulfonated, Oxidized and its Potassium
and Sodium Salts; 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 9-octadecenoic acid (9Z)-, sulfonated,
oxidized; 9-octadecenoic acid (9Z)-, sulfonated, oxidized, potassium
salts; and 9-octadecenoic acid (9Z)-, sulfonated, oxidized, sodium
salts, when used as an inert ingredient in antimicrobial pesticide
formulations used on food contact surfaces in public eating places,
dairy processing equipment and food processing equipment and utensils
at a maximum end-use concentration not to exceed 250 parts per million
(ppm). Ecolab submitted a petition to EPA under the Federal Food, Drug,
and Cosmetic Act (FFDCA), requesting establishment of an exemption from
the requirement of a tolerance. This regulation eliminates the need to
establish a maximum permissible level for residues of 9-octadecenoic
acid (9Z)-, sulfonated, oxidized and its potassium and sodium salts.
DATES: This regulation is effective March 4, 2015. Objections and
requests for hearings must be received on or before May 4, 2015, and
must be filed in accordance with the instructions provided in 40 CFR
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

346a, announcing the filing of a pesticide petition (PP IN-10549) by
Ecolab, Inc. 370 N. Wabasha Street, St. Paul, MN 55102. The petition
requested that 40 CFR 180.940(a) be amended by establishing an
exemption from the requirement of a tolerance for residues of 9-
octadecenoic acid (9Z)-, sulfonated, oxidized (CAS Reg. No. 1315321-93-
7); 9-octadecenoic acid (9Z)-, sulfonated, oxidized, potassium salts
(CAS Reg. No. 1315321-94-8); and 9-octadecenoic acid (9Z)-, sulfonated,
oxidized, sodium salts, (CAS No. 1315321-95-9) when used as an inert
ingredient in antimicrobial pesticide formulations used on food contact
surfaces in public eating places, dairy processing equipment, and food
processing equipment and utensils at a maximum end-use concentration
not to exceed 250 ppm. That document referenced a summary of the
petition prepared by Ecolab Inc, the petitioner, which is available in
the docket, https://www.regulations.gov. There were no
[[Page 11590]]
comments received in response to the notice of filing.
III. Inert Ingredient Definition
Inert ingredients are all ingredients that are not active
ingredients as defined in 40 CFR 153.125 and include, but are not
limited to, the following types of ingredients (except when they have a
pesticidal efficacy of their own): Solvents such as alcohols and
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty
acids; carriers such as clay and diatomaceous earth; thickeners such as
carrageenan and modified cellulose; wetting, spreading, and dispersing
agents; propellants in aerosol dispensers; microencapsulating agents;
and emulsifiers. The term ``inert'' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active.
Generally, EPA has exempted inert ingredients from the requirement of a
tolerance based on the low toxicity of the individual inert
ingredients.
IV. Aggregate Risk Assessment and Determination of Safety
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for a tolerance (the legal limit for a
pesticide chemical residue in or on a food) only if EPA determines that
the tolerance is ``safe.'' Section 408(b)(2)(A)(ii) of FFDCA defines
``safe'' to mean that ``there is a reasonable certainty that no harm
will result from aggregate exposure to the pesticide chemical residue,
including all anticipated dietary exposures and all other exposures for
which there is reliable information.'' This includes exposure through
drinking water and in residential settings, but does not include
occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure of infants and children to the
pesticide chemical residue in establishing a tolerance and to ``ensure
that there is a reasonable certainty that no harm will result to
infants and children from aggregate exposure to the pesticide chemical
residue. . . .''
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be clearly demonstrated that the risks from
aggregate exposure to pesticide chemical residues under reasonably
foreseeable circumstances will pose no appreciable risks to human
health. In order to determine the risks from aggregate exposure to
pesticide inert ingredients, the Agency considers the toxicity of the
inert in conjunction with possible exposure to residues of the inert
ingredient through food, drinking water, and through other exposures
that occur as a result of pesticide use in residential settings. If EPA
is able to determine that a finite tolerance is not necessary to ensure
that there is a reasonable certainty that no harm will result from
aggregate exposure to the inert ingredient, an exemption from the
requirement of a tolerance may be established.
Consistent with FFDCA section 408(c)(2)(A), and the factors
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for 9-octadecenoic acid (9Z)-,
sulfonated, oxidized and its potassium and sodium salts including
exposure resulting from the exemption established by this action. EPA's
assessment of exposures and risks associated with 9-octadecenoic acid
(9Z)-, sulfonated, oxidized and its potassium and sodium salts follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. Specific information on the studies received and the nature
of the adverse effects caused by 9-octadecenoic acid (9Z)-, sulfonated,
oxidized and its potassium and sodium salt (also referred to as peroxy
sulfonated oleic acid (PSOA)) as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies discussed in this unit.
Peroxy sulfonated oleic acid is acutely toxic via the oral route
and is highly corrosive via the dermal and inhalation routes of
exposure. In a 28-day oral toxicity study (OECD Guideline 407), rats
were administered PSOA via gavage at dose levels of 15 milligrams/
kilogram/day (mg/kg/day) and 50 mg/kg/day. No observable adverse
effects were seen at either dose level but since no systemic effects
were observed, the dosing was considered by the Agency to not be
adequate.
In a developmental toxicity (OECD Guideline 414) study with PSOA,
the parental NOAEL for systemic effects was 50 mg/kg bw/day, the
highest dose tested. The NOAEL for embryotoxic, fetotoxic and
developmental effects was also 50 mg/kg bw/day, the highest dose
tested.
The dosing in the 28-day gavage study and the developmental
toxicity studies was considered inadequate because animals were not
challenged at higher doses. The applicant suggested that the higher
doses were not utilized because of the corrosive nature of the
chemical. Since there was no evidence of corrosivity in the study, a
14-day oral toxicity study was conducted at dose levels of 100 mg/kg/
day, 300 mg/kg/day and 1,000 mg/kg/day. The study results confirmed
that higher doses would have been corrosive.
In a series of genotoxicity studies PSOA is negative for inducing
mutations in bacterial and mammalian cells, with and without metabolic
activation. In the in vitro chromosome aberration study using human
lymphocytes, PSOA was positive with and without metabolic activation.
However, the in vivo micronucleus assay in rats was negative.
A neurotoxicity study was not conducted with PSOA. However,
detailed functional observations were made among the parameters
measured in the 28-day subchronic oral feeding study. There were no
PSOA related changes in any of the parameters measured, including
functional observations battery (FOB). No evidence of neurotoxicity was
observed. An immunotoxicity study was not conducted with PSOA. However,
minimal hemorrhage in the thymus was observed after the recovery period
in the 14-day oral toxicity study with rats. Since, this effect is a
common background lesion it is not considered indicative of potential
immunotoxicity. There are no known chronic toxicity studies with PSOA
and no available PSOA mammalian metabolism studies.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe
[[Page 11591]]
exposure level--generally referred to as a population-adjusted dose
(PAD) or a reference dose (RfD)--and a safe margin of exposure (MOE).
For non-threshold risks, the Agency assumes that any amount of exposure
will lead to some degree of risk. Thus, the Agency estimates risk in
terms of the probability of an occurrence of the adverse effect
expected in a lifetime. For more information on the general principles
EPA uses in risk characterization and a complete description of the
risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.

C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to PSOA, EPA considered exposure under the proposed exemption
from the requirement of a tolerance. EPA assessed dietary exposures
from peroxy sulfonated oleic acids in food as follows:
In the absence of actual dietary exposure data resulting from this
use, EPA has utilized a conservative, health-protective method of
estimating dietary intake that is based upon conservative assumptions
related to the amount of residues that can be transferred to foods as a
result of the proposed use of 9-octadecenoic acid (9Z)-, sulfonated,
oxidized and its potassium and sodium salts in food contact sanitizing
pesticide products. This same methodology has been utilized by EPA in
estimating dietary exposures to antimicrobial pesticides used in food-
handling settings. A complete description of the approach used to
assess dietary exposures resulting from food contact sanitizing
solution uses of nitric acid can be found at https://www.regulations.gov
in document ``Peroxy Sulfonated Oleic Acids; Human Health Risk
Assessment and Ecological Effects Assessment to Support Proposed
Exemption from the Requirement of a Tolerance When Used as Inert
Ingredients in Pesticide Formulations,'' pp. 14-15 in docket ID number
EPA-HQ-OPP-2013-0601. EPA assessed dietary exposures from 9-
octadecenoic acid (9Z)-, sulfonated, oxidized and its potassium and
sodium salts in food as follows:
i. Acute exposure. No adverse effects attributable to a single
exposure of PSOA were seen in the toxicity databases. Therefore, an
acute dietary exposure assessment for 9-octadecenoic acid (9Z)-,
sulfonated, oxidized and its potassium and sodium salts is not
necessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment, the Agency believes the assumptions used to estimate
chronic dietary exposures lead to an extremely conservative assessment
of chronic dietary risk due to a series of compounded conservative
assumptions. First, when a surface is treated with a disinfectant, a
quantity of the disinfectant remains on the surface (residual
solution). In the absence of any other data, EPA has used an estimated
worst-case concentration of 1 mg of residual solution per square
centimeter (cm) of treated surface area for this quantity. Second, the
conservatism of this methodology is compounded by EPA's decision to
assume a worst case scenario that all food that an individual consumers
will come into contact with 4,000 cm\2\ of sanitized non-porous food
contact surfaces. This contact area represents all the surface area
from silverware, china, and glass used by a person who regularly eats
three meals per day at an institutional or public facility. Third, EPA
assumes that 100% of the material present on food contact surfaces will
migrate to food.
2. Dietary exposure from drinking water. Due to the proposed use
pattern, the Agency believes PSOA will not enter surface water or
ground water as a result of the proposed use. Therefore a dietary
exposure assessment for drinking water is not necessary.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure. Peroxy sulfonated oleic acids are not used as an inert
ingredient in pesticide products that are registered for specific uses
that may result in both indoor and outdoor residential exposures.
Therefore, a residential exposure and risk assessment was not conducted
for PSOA.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found peroxy sulfonated oleic acids to share a common
mechanism of toxicity with any other substances, and peroxy sulfonated
oleic acids do not appear to produce a toxic metabolite produced by
other substances. For the purposes of this tolerance action, therefore,
EPA has assumed that peroxy sulfonated oleic acids do not have a common
mechanism of toxicity with other substances. For information regarding
EPA's efforts to determine which chemicals have a common mechanism of
toxicity and to evaluate the cumulative effects of such
[[Page 11592]]
chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no concern for
fetal susceptibility. There were no treatment related effects observed
in a developmental toxicity study in rats up to the maximum dose tested
(50 mg/kg/day). Based on the corrosive nature of PSOA toxicity testing
at doses greater than 100 mg/kg/day results in local effects (i.e.,
severe gastrointestinal irritation) with other observed systemic
effects being secondary to the irritation effects. Therefore, based on
the available data, there are no concerns for residual uncertainties
concerning prenatal and postnatal toxicity.
3. Conclusion. EPA has determined that reliable data show the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1X. That decision is based on the following
findings:
i. The NOAEL used for risk assessment is based on the corrosive
effects of PSOA which occur at dose levels below which any systemic
toxicity is observed and is therefore protective of potential
developmental and reproductive effects.
ii. There is no indication that PSOA is a neurotoxic chemical and
there is no need for a developmental neurotoxicity study or additional
UFs to account for neurotoxicity.
iii. There is no indication that PSOA is an immunotoxic chemical
and there is no need for additional UFs to account for immunotoxicity.
iv. There is no evidence that PSOA results in increased
susceptibility in in utero rodents.
v. There are no residual uncertainties identified in the exposure
databases. EPA made conservative (health-protective) assumptions
regarding dietary exposure to PSOA. This assessment will not
underestimate the exposure and risks posed by PSOA.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic pesticide exposures are
safe by comparing aggregate exposure estimates to the acute PAD (aPAD)
and chronic PAD (cPAD). The aPAD and cPAD represent the highest safe
exposures, taking into account all appropriate SFs. EPA calculates the
aPAD and cPAD by dividing the POD by all applicable UFs. For linear
cancer risks, EPA calculates the probability of additional cancer cases
given the estimated aggregate exposure. Short-, intermediate-, and
chronic-term risks are evaluated by comparing the estimated aggregate
food, water, and residential exposure to the POD to ensure that the MOE
called for by the product of all applicable UFs is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effect resulting from a single oral exposure
was identified and no acute dietary endpoint was selected. Therefore,
peroxy sulfonated oleic acids are not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
peroxy sulfonated oleic acids from food and water will utilize 18% of
the cPAD for children 1-2 years old, the population group receiving the
highest exposure. There are no residential uses for peroxy sulfonated
oleic acids. Based on the explanation in Unit IIIC.3 residential use
patterns, chronic residential exposure to residues of peroxy sulfonated
oleic acids is not expected.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Because there
are no residential uses, short-term residential exposures are not
likely to occur, and no short-term adverse effect was identified
therefore peroxy sulfonated oleic acids are not expected to pose a
short-term aggregate risk.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Because there are no residential uses, intermediate-term
residential exposures are not likely to occur, and peroxy sulfonated
oleic acids are not expected to pose an intermediate-term aggregate
risk.
5. Aggregate cancer risk for U.S. population. Based upon negative
response for mutagenicity in a battery of genotoxicity tests, and lack
of any structural alerts for carcinogenicity, peroxy sulfonated oleic
acids are not expected to pose a cancer risk to humans.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to peroxy sulfonated oleic acids residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is not establishing a numerical tolerance for residues of
peroxy sulfonated oleic acids of in or on any food commodities. EPA is
establishing a limitation on the amount of peroxy sulfonated oleic
acids that may be used in pesticide formulations. That limitation will
be enforced through the pesticide registration process under the
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), 7 U.S.C.
136 et seq. EPA will not register any pesticide for sale or
distribution for which the final end use concentration of peroxy
sulfonated oleic acids in antimicrobial food contact surface sanitizing
solutions would exceed 250 ppm.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nation Food
and Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for peroxy sulfonated oleic
acids.
[[Page 11593]]
VI. Conclusions
Therefore, an exemption from the requirement of a tolerance is
established under 40 CFR 180.940(a) for residues of 9-octadecenoic acid
(9Z)-, sulfonated, oxidized (CAS Reg. No. 1315321-93-7); 9-octadecenoic
acid (9Z)-, sulfonated, oxidized, potassium salts (CAS Reg. No.
1315321-94-8); and 9-octadecenoic acid (9Z)-, sulfonated, oxidized,
sodium salts, (CAS No. 1315321-95-9) when used as an inert ingredient
in antimicrobial pesticide formulations used on food contact surfaces
in public eating places, dairy processing equipment and food processing
equipment and utensils at a maximum end-use concentration not to exceed
250 ppm.
VII. Statutory and Executive Order Reviews
This action establishes a tolerance under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian Tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VIII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
