Peroxyacetic Acid; Amendment to an
Exemption From the Requirement of a
Tolerance
Environmental Protection
Agency (EPA).
ACTION: Final rule.
AGENCY:
This regulation amends the
existing tolerance exemption for
peroxyacetic acid by establishing an
exemption from the requirement of a
tolerance for residues of the biochemical
pesticide peroxyacetic acid (PAA) and
its metabolites and degradates,
including hydrogen peroxide (HP) and
acetic acid (AA), in or on all food
commodities, when PAA is used as a
biochemical pesticide in accordance
with good agricultural practices. BioSafe
Systems, LLC submitted a petition to
EPA under the Federal Food, Drug, and
Cosmetic Act (FFDCA), requesting that
EPA amend the existing PAA tolerance
exemption. This regulation eliminates
the need to establish a maximum
permissible level for residues of PAA
under the FFDCA.
DATES: This regulation is effective
March 4, 2011. Objections and requests
for hearings must be received on or
before May 3, 2011, 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 February
13, 2008 (73 FR 8311) (FRL–8349–5),
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 7F7262)
by BioSafe Systems, LLC, 22 Meadow
Street, East Hartford, CT 06108. The
petition proposed to establish an
exemption from the requirement of a
tolerance for residues of the biochemical
pesticide, peroxyacetic acid in or on all
agricultural commodities when used as
a biochemical pesticide. This notice
referenced a summary of the petition
prepared by the petitioner, BioSafe
Systems, LLC, which is available in the
docket, https://www.regulations.gov.
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
VerDate Mar<15>2010
13:26 Mar 03, 2011
Jkt 223001
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 exemption 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 EPA
consider ‘‘available information
concerning the cumulative effects of [a
particular pesticide’s] residues and
other substances that have a common
mechanism of toxicity.’’
Section 408(a)(3) of FFDCA states that
residues of metabolites or degradates of
pesticide chemicals ‘‘shall not be
considered to be unsafe * * * despite
the lack of a tolerance or exemption
from the need for a tolerance for such
residue in or on such food’’ if three
conditions are met. First, the Agency
must not have determined that the
degradation product ‘‘is likely to pose
any potential health risk from dietary
exposure that is of a different type than,
or of a greater significance than, any risk
posed by dietary exposure to the
precursor substance’’. Second, for
purposes of this action, an exemption
exists for residues of the precursor
substance. Third, again for purposes of
this action, the exemption for residues
of the precursor substance does not
expressly exclude residues of the
metabolites or degradates.
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
PO 00000
Frm 00030
Fmt 4700
Sfmt 4700
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.
A. Overview
The purpose of this rulemaking is to
amend the existing tolerance exemption
for PAA to allow for residues of PAA
and its metabolites and degradates,
including HP and AA in or on all food
commodities, when such residues result
from its use as a biochemical pesticide
in accordance with good agricultural
practices. At high concentrations, PAA
is a highly corrosive, colorless, organic
compound that is formed, and only
exists in equilibrium, with hydrogen
peroxide and acetic acid. The current
exemptions for residues of PAA allow
application of PAA, after dilution to
specific concentrations in parts per
million (ppm), as an antimicrobial
treatment to fruits, vegetables, tree nuts,
cereal grains, herbs, spices, and as a
sanitizing solution to tableware,
utensils, dishes, pipelines, tanks, vats,
fillers, evaporators, pasteurizers, aseptic
equipment, milking equipment, and
food processing equipment in food
handling establishments. (40 CFR
180.1196).
B. Toxicity of PAA
1. Acute toxicity. Acute toxicity data
and information submitted to support
the exemption from the requirement of
a tolerance for peroxyacetic acid were
conducted on the technical blend of
peroxyacetic acid, acetic acid and
hydrogen peroxide. PAA is always sold
in solution with AA and HP to maintain
stability of the chemical. Further, all
three active ingredients have an
identical mode of action as strong
oxidizing agents that disrupt cell
membranes because of the low ph. This
information confirms the toxicity profile
of peroxyacetic acid, acetic acid and
hydrogen peroxide. The results of the
toxicology studies as conducted on the
technical blend are reported in the table
of Unit III.B.1.

TABLE—TOXICOLOGY STUDIES RESULTS
Study type
Study results
Acute oral toxicity ............................
The acute oral median LD50 = 3,622 milligrams/kilograms (mg/kg) for male and female rats given a solution
containing 5.6% PAA, 26.9% H2O2, and 7.6% HOAc. This technical blend is Toxicity category III for
acute oral toxicity. (Master Record Identification Number [MRID No.] 47237802, Ref. 1). (ECETOC, Ref.
2).
The acute dermal LD50 = 1,040 mg/kg (Tox category II) for female rabbits after a 24-hr semi-occlusive exposure to a solution containing 4.89% PAA, 19.72% H2O2, and 10% HOAc. (Ref. 1 and 2).
The acute inhalation median LC50 > 5.35 mg/L for male and female rats exposed for 4 hr to aerosol of solution containing 4.5% PAA, 27% H2O2, and 16.7% HOAc. (Ref. 1 and 2).
Due to pH of 0.82 for 2.0% solution and pH 0.82 for 5.0% solution, PAA is assumed to be a severe irritant;
≥ 0.2% PAA was severely irritating or corrosive to the eye, 0.15% was mildly irritating to the rabbit eye,
and 0.034% caused very slight irritation. (Ref. 1 and 2).
Due to pH of 0.82 for 2.0% solution and pH 0.82 for 5.0% solution, PAA is assumed to be a severe irritant.

2. Subchronic toxicity. Based on its
acute toxicity profile, use pattern and
biodegradation properties, rapid
degradation half lives for degradates,
residues of PAA and its degradates,
including AA and HP, are not expected
to result in significant dietary exposure
beyond the levels expected in
background dietary exposures.
Nonetheless, information from the open
scientific literature to address the
subchronic oral, dermal and inhalation
toxicity guidelines testing, satisfied the
data requirements for subchronic
toxicity and indicated that PAA and its
degradates have no subchronic
toxicological effect.
C. Degradates of PAA
PAA degrades rapidly to AA and HP,
and HP further degrades to water and
oxygen; therefore, the final degradation
products of PAA are AA, water, and
oxygen. As stated in Unit II., section
408(a)(3) allows degradates of precursor
substances to be covered by the
exemption for the precursor substance
as long as, inter alia, the Administrator
has not determined that the degradation
product ‘‘is likely to pose any potential
health risk from dietary exposure that is
of a different type than, or of a greater
significance than, any risk posed by
dietary exposure to the precursor
substance’’. For PAA and its degradates
AA and HP, EPA has made no such
determination. The following discussion
summarizes the Agency’s previous
assessments of AA and HP.
1. Acetic acid. AA is a substance
found in most plants and animals,
including primates and humans, and is
naturally produced during the
fermentation process in a wide range of
foods. Furthermore, AA has a long
history of use as a food additive, is the
main acid in vinegar, and is found in
wine, beer, and similarly brewed
beverages and fermented food items
(e.g., sauerkraut). The Food and Drug
Administration (FDA) classifies AA as
VerDate Mar<15>2010
13:26 Mar 03, 2011
Jkt 223001
Generally Recognized as Safe (GRAS) as
a direct food substance (21 CFR
184.1005) and as a general purpose food
additive (21 CFR 582.1005).
Furthermore, information from the open
literature indicates that AA has little or
no toxicity from an acute oral
perspective (toxicity category III;
median lethal dose (LD50) = 3,310 mg/
kg). Data also indicate that AA has no
subchronic, developmental, or
mutagenic toxicological effects. (Ref. 3).
2. Hydrogen peroxide. Previously,
EPA assessed HP for potential risks to
the U.S. population, including infants
and children, and concluded that, since
HP itself degrades rapidly into oxygen
and water, residues of a solution that
contains 1% HP are not expected to
remain in or on food. Hydrogen
peroxide is listed by the FDA as GRAS.
Additionally, hydrogen peroxide is used
to treat food at a maximum level of
0.05% in milk used in cheesemaking,
0.04% in whey, 0.15% in starch and
corn syrup, and 1.25% in emulsifiers
containing fatty acid esters as bleaching
agents (21 CFR 184.1366). As a GRAS
substance, hydrogen peroxide may be
used in washing or to assist in the lye
peeling of fruits and vegetables (21 CFR
173.315). The information from open
literature demonstrated that solutions
containing 6% hydrogen peroxide have
an acute oral LD50 >/= 5,000 mg/kg in
rats (toxicity category III), an acute
dermal LD50 >/= 10,000 mg/kg in rabbits
(toxicity category IV), and an inhalation
LC50 of 4 milligram/liter (mg/L) (toxicity
category IV). The 6% hydrogen peroxide
solutions are mild irritants to rabbit skin
and cause severe irreversible corneal
injury in half of the exposed rabbits
(toxicity category I). Toxicology
information from open literature
demonstrated that solutions which
contained 50% hydrogen peroxide have
an acute oral LD50 < 500 mg/kg in rats
(toxicity category II), and an acute
dermal LD50 < 1,000 mg/kg in rabbits
PO 00000
Frm 00031
Fmt 4700
Sfmt 4700
(toxicity category II). No deaths resulted
after an 8-hour exposure of rats to
saturated vapors of 90% hydrogen
peroxide, LC50 = 4 mg/L (2,000 ppm).
Solutions which contain 50% hydrogen
peroxide also are extremely irritating
(corrosive) to rabbit eyes (toxicity
category I). EPA has concluded that for
food use at an application rate of 1%,
hydrogen peroxide has no apparent
acute toxicity and subchronic toxicity
end points exist to suggest a significant
toxicity. An RfD (chronic toxicity) for
hydrogen peroxide has not been
estimated because of its short half-life in
the environment and lack of any
residues of toxicological concern. (Ref.
4).
IV. Aggregate Exposure
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).
A. Dietary Exposure
Dietary exposure to residues of PAA
and its degradate components, AA and
HP, are expected to be virtually
nonexistent at the time of consumption.
Even in the event of unlikely exposure,
the information supporting this
tolerance exemption demonstrates that
any dietary risks would be negligible.
1. Food. When used as a soil
treatment, the Agency does not expect
there to be any residues of PAA or its
degradates because PAA breaks down
rapidly on contact with soil, which
precludes uptake of PAA by plants. The
rate of degradation can be affected by
the concentration of PAA in a solution
and environmental conditions (e.g.,
temperature and pH of the environment
E:\FR\FM\04MRR1.SGM
04MRR1
11968
Federal Register / Vol. 76, No. 43 / Friday, March 4, 2011 / Rules and Regulations
in which the PAA is applied), but the
Agency expects that PAA, when used as
a biochemical pesticide for applications
to soil or foliage or greenhouse
structures, will likely degrade within 24
hours following application. This is
because good agricultural practices
generally require a soil pH of 5 to 7, at
which level PAA degrades in less than
24 hours. Regardless of the time
required for PAA to break down, the use
of this biochemical pesticide as a preplant soil treatment would occur before
any food crops would be present, and
degradation would prevent uptake by
plants; thus, no residues are expected
from use as a soil treatment to sterilize
the soil and kill pathogens in soils.
When used to treat plants directly, the
Agency anticipates that PAA will be
applied to the plant at concentrations
that will not cause damage to the plant.
At such concentrations, the Agency
expects PAA to degrade within 24 hours
into AA, oxygen, and water because
PAA begins to degrade immediately
upon contact with organic matter.
Therefore, the Agency has determined
that there will be little to no exposure
to PAA from direct treatment of plants.
2. Drinking water exposure. The
Agency expects there to be little to no
exposure of humans to PAA and its
degradates in drinking water since PAA
degrades quickly in water, i.e., within
24 hours, especially water bodies with
neutral or alkaline pH levels, into AA,
oxygen, and water. In the event that
residues of the degradates are present,
the levels of the degradates do not
present a risk concern based on the
foreseeable rates at which PAA is likely
to be applied.
jdjones on DSK8KYBLC1PROD with RULES2
B. Other Non-Occupational Exposure
Non-occupational exposure is not
expected since PAA rapidly degrades
and is non-persistent in the
environment.
V. 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, EPA 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 peroxyacetic acid
to share a common mechanism of
toxicity with any other substances, and
peroxyacetic acid does not appear to
produce a toxic metabolite as its mode
of action against the target pests. For the
purposes of this tolerance action,
therefore, EPA has assumed that
peroxyacetic acid does not have a
VerDate Mar<15>2010
13:26 Mar 03, 2011
Jkt 223001
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.
VI. Determination of Safety for U.S.
Population, Infants and Children
1. U.S. population. Based on the lack
of exposure to much, if any, PAA and
its metabolites and degradates,
including HP and AA, the Agency has
concluded that there is reasonable
certainty that no harm will result to the
general U.S. population, including
infants and children, from aggregate
exposure to PAA and its metabolites
and degradates, including HP and AA.
This includes all anticipated dietary
exposures and all other exposures for
which there is reliable information.
2. Infants and children. FFDCA
section 408(b)(2)(C) provides that EPA
shall apply an additional tenfold margin
of exposure (MOE) for infants and
children in the case of threshold effects
to account for prenatal and postnatal
toxicity and the completeness of the
data base on toxicity and exposure,
unless EPA determines that a different
MOE will be safe for children. MOEs,
which are often referred to as
uncertainty (safety) factors, are
incorporated into EPA risk assessments
either directly, or through the use of a
MOE analysis or by using uncertainty
factors in calculating a dose level that
poses no appreciable risk. Because there
are no threshold effects of concern to
infants, children, and adults from PAA
and its metabolites or degradates,
including HP and AA, the Agency
concludes that the additional MOE is
not necessary to protect infants and
children and that removing the FQPA
safety factor will be safe for infants and
children.
VII. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since EPA is
establishing an exemption from the
requirement of a tolerance without any
numerical limitation.
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
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint U.N.
Food and Agriculture Organization/
World Health Organization food
standards program, and it is recognized
as an international food safety
standards-setting organization in trade
agreements to which the United States
is a party. EPA may establish a tolerance
that is different from a Codex MRL;
however, FFDCA section 408(b)(4)
requires that EPA explain the reasons
for departing from the Codex level.
The Codex has not established a MRL
for peroxyacetic acid.
VIII. Conclusions
EPA concludes that there is a
reasonable certainty that no harm will
result to the U.S. population, including
infants and children, from aggregate
exposure to residues of peroxyacetic
acid and its metabolites and degradates,
including AA and HP. Therefore, the
existing tolerance exemption for PAA is
amended to establish a tolerance
exemption for residues of the
biochemical pesticide, peroxyacetic
acid, in or on all food commodities,
when used in accordance with good
agricultural practices.

X. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
exemption under section 408(d) of
FFDCA in response to a petition
submitted to EPA. 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

jdjones on DSK8KYBLC1PROD with RULES2
Federal Register / Vol. 76, No. 43 / Friday, March 4, 2011 / Rules and Regulations
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 tolerance 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.
As a result, this action does not alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
EPA 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, EPA has determined that
Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999), and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 9, 2000), do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Pub. L. 104–4).
This action does not involve any
technical standards that would require
EPA 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).

Peroxyacetic Acid; Amendment to an Exemption From the Requirement
of a Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation amends the existing tolerance exemption for
peroxyacetic acid by establishing an exemption from the requirement of
a tolerance for residues of the biochemical pesticide peroxyacetic acid
(PAA) and its metabolites and degradates, including hydrogen peroxide
(HP) and acetic acid (AA), in or on all food commodities, when PAA is
used as a biochemical pesticide in accordance with good agricultural
practices. BioSafe Systems, LLC submitted a petition to EPA under the
Federal Food, Drug, and Cosmetic Act (FFDCA), requesting that EPA amend
the existing PAA tolerance exemption. This regulation eliminates the
need to establish a maximum permissible level for residues of PAA under
the FFDCA.
DATES: This regulation is effective March 4, 2011. Objections and
requests for hearings must be received on or before May 3, 2011, 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 February 13, 2008 (73 FR 8311) (FRL-
8349-5), 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 7F7262) by BioSafe Systems, LLC, 22 Meadow Street, East
Hartford, CT 06108. The petition proposed to establish an exemption
from the requirement of a tolerance for residues of the biochemical
pesticide, peroxyacetic acid in or on all agricultural commodities when
used as a biochemical pesticide. This notice referenced a summary of
the petition prepared by the petitioner, BioSafe Systems, LLC, which is
available in the docket, https://www.regulations.gov. 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 exemption 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 EPA consider ``available information concerning the cumulative
effects of [a particular pesticide's] residues and other substances
that have a common mechanism of toxicity.''
Section 408(a)(3) of FFDCA states that residues of metabolites or
degradates of pesticide chemicals ``shall not be considered to be
unsafe * * * despite the lack of a tolerance or exemption from the need
for a tolerance for such residue in or on such food'' if three
conditions are met. First, the Agency must not have determined that the
degradation product ``is likely to pose any potential health risk from
dietary exposure that is of a different type than, or of a greater
significance than, any risk posed by dietary exposure to the precursor
substance''. Second, for purposes of this action, an exemption exists
for residues of the precursor substance. Third, again for purposes of
this action, the exemption for residues of the precursor substance does
not expressly exclude residues of the metabolites or degradates.
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. 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.
A. Overview
The purpose of this rulemaking is to amend the existing tolerance
exemption for PAA to allow for residues of PAA and its metabolites and
degradates, including HP and AA in or on all food commodities, when
such residues result from its use as a biochemical pesticide in
accordance with good agricultural practices. At high concentrations,
PAA is a highly corrosive, colorless, organic compound that is formed,
and only exists in equilibrium, with hydrogen peroxide and acetic acid.
The current exemptions for residues of PAA allow application of PAA,
after dilution to specific concentrations in parts per million (ppm),
as an antimicrobial treatment to fruits, vegetables, tree nuts, cereal
grains, herbs, spices, and as a sanitizing solution to tableware,
utensils, dishes, pipelines, tanks, vats, fillers, evaporators,
pasteurizers, aseptic equipment, milking equipment, and food processing
equipment in food handling establishments. (40 CFR 180.1196).
B. Toxicity of PAA
1. Acute toxicity. Acute toxicity data and information submitted to
support the exemption from the requirement of a tolerance for
peroxyacetic acid were conducted on the technical blend of peroxyacetic
acid, acetic acid and hydrogen peroxide. PAA is always sold in solution
with AA and HP to maintain stability of the chemical. Further, all
three active ingredients have an identical mode of action as strong
oxidizing agents that disrupt cell membranes because of the low ph.
This information confirms the toxicity profile of peroxyacetic acid,
acetic acid and hydrogen peroxide. The results of the toxicology
studies as conducted on the technical blend are reported in the table
of Unit III.B.1.
[[Page 11967]]
Table--Toxicology Studies Results
------------------------------------------------------------------------
Study type Study results
------------------------------------------------------------------------
Acute oral toxicity............... The acute oral median LD50 = 3,622
milligrams/kilograms (mg/kg) for
male and female rats given a
solution containing 5.6% PAA, 26.9%
H2O2, and 7.6% HOAc. This technical
blend is Toxicity category III for
acute oral toxicity. (Master Record
Identification Number [MRID No.]
47237802, Ref. 1). (ECETOC, Ref.
2).
Acute dermal toxicity............. The acute dermal LD50 = 1,040 mg/kg
(Tox category II) for female
rabbits after a 24-hr semi-
occlusive exposure to a solution
containing 4.89% PAA, 19.72% H2O2,
and 10% HOAc. (Ref. 1 and 2).
Acute inhalation toxicity......... The acute inhalation median LC50 >
5.35 mg/L for male and female rats
exposed for 4 hr to aerosol of
solution containing 4.5% PAA, 27%
H2O2, and 16.7% HOAc. (Ref. 1 and
2).
Primary eye irritation............ Due to pH of 0.82 for 2.0% solution
and pH 0.82 for 5.0% solution, PAA
is assumed to be a severe irritant;
>= 0.2% PAA was severely irritating
or corrosive to the eye, 0.15% was
mildly irritating to the rabbit
eye, and 0.034% caused very slight
irritation. (Ref. 1 and 2).
Primary dermal irritation......... Due to pH of 0.82 for 2.0% solution
and pH 0.82 for 5.0% solution, PAA
is assumed to be a severe irritant.
(Ref. 1 and 2).
------------------------------------------------------------------------
2. Subchronic toxicity. Based on its acute toxicity profile, use
pattern and biodegradation properties, rapid degradation half lives for
degradates, residues of PAA and its degradates, including AA and HP,
are not expected to result in significant dietary exposure beyond the
levels expected in background dietary exposures. Nonetheless,
information from the open scientific literature to address the
subchronic oral, dermal and inhalation toxicity guidelines testing,
satisfied the data requirements for subchronic toxicity and indicated
that PAA and its degradates have no subchronic toxicological effect.
C. Degradates of PAA
PAA degrades rapidly to AA and HP, and HP further degrades to water
and oxygen; therefore, the final degradation products of PAA are AA,
water, and oxygen. As stated in Unit II., section 408(a)(3) allows
degradates of precursor substances to be covered by the exemption for
the precursor substance as long as, inter alia, the Administrator has
not determined that the degradation product ``is likely to pose any
potential health risk from dietary exposure that is of a different type
than, or of a greater significance than, any risk posed by dietary
exposure to the precursor substance''. For PAA and its degradates AA
and HP, EPA has made no such determination. The following discussion
summarizes the Agency's previous assessments of AA and HP.
1. Acetic acid. AA is a substance found in most plants and animals,
including primates and humans, and is naturally produced during the
fermentation process in a wide range of foods. Furthermore, AA has a
long history of use as a food additive, is the main acid in vinegar,
and is found in wine, beer, and similarly brewed beverages and
fermented food items (e.g., sauerkraut). The Food and Drug
Administration (FDA) classifies AA as Generally Recognized as Safe
(GRAS) as a direct food substance (21 CFR 184.1005) and as a general
purpose food additive (21 CFR 582.1005). Furthermore, information from
the open literature indicates that AA has little or no toxicity from an
acute oral perspective (toxicity category III; median lethal dose
(LD50) = 3,310 mg/kg). Data also indicate that AA has no
subchronic, developmental, or mutagenic toxicological effects. (Ref.
3).
2. Hydrogen peroxide. Previously, EPA assessed HP for potential
risks to the U.S. population, including infants and children, and
concluded that, since HP itself degrades rapidly into oxygen and water,
residues of a solution that contains 1% HP are not expected to remain
in or on food. Hydrogen peroxide is listed by the FDA as GRAS.
Additionally, hydrogen peroxide is used to treat food at a maximum
level of 0.05% in milk used in cheesemaking, 0.04% in whey, 0.15% in
starch and corn syrup, and 1.25% in emulsifiers containing fatty acid
esters as bleaching agents (21 CFR 184.1366). As a GRAS substance,
hydrogen peroxide may be used in washing or to assist in the lye
peeling of fruits and vegetables (21 CFR 173.315). The information from
open literature demonstrated that solutions containing 6% hydrogen
peroxide have an acute oral LD50 >/= 5,000 mg/kg in rats
(toxicity category III), an acute dermal LD50 >/= 10,000 mg/
kg in rabbits (toxicity category IV), and an inhalation LC50
of 4 milligram/liter (mg/L) (toxicity category IV). The 6% hydrogen
peroxide solutions are mild irritants to rabbit skin and cause severe
irreversible corneal injury in half of the exposed rabbits (toxicity
category I). Toxicology information from open literature demonstrated
that solutions which contained 50% hydrogen peroxide have an acute oral
LD50 < 500 mg/kg in rats (toxicity category II), and an
acute dermal LD50 < 1,000 mg/kg in rabbits (toxicity
category II). No deaths resulted after an 8-hour exposure of rats to
saturated vapors of 90% hydrogen peroxide, LC50 = 4 mg/L
(2,000 ppm). Solutions which contain 50% hydrogen peroxide also are
extremely irritating (corrosive) to rabbit eyes (toxicity category I).
EPA has concluded that for food use at an application rate of 1%,
hydrogen peroxide has no apparent acute toxicity and subchronic
toxicity end points exist to suggest a significant toxicity. An RfD
(chronic toxicity) for hydrogen peroxide has not been estimated because
of its short half-life in the environment and lack of any residues of
toxicological concern. (Ref. 4).
IV. Aggregate Exposure
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).
A. Dietary Exposure
Dietary exposure to residues of PAA and its degradate components,
AA and HP, are expected to be virtually nonexistent at the time of
consumption. Even in the event of unlikely exposure, the information
supporting this tolerance exemption demonstrates that any dietary risks
would be negligible.
1. Food. When used as a soil treatment, the Agency does not expect
there to be any residues of PAA or its degradates because PAA breaks
down rapidly on contact with soil, which precludes uptake of PAA by
plants. The rate of degradation can be affected by the concentration of
PAA in a solution and environmental conditions (e.g., temperature and
pH of the environment
[[Page 11968]]
in which the PAA is applied), but the Agency expects that PAA, when
used as a biochemical pesticide for applications to soil or foliage or
greenhouse structures, will likely degrade within 24 hours following
application. This is because good agricultural practices generally
require a soil pH of 5 to 7, at which level PAA degrades in less than
24 hours. Regardless of the time required for PAA to break down, the
use of this biochemical pesticide as a pre-plant soil treatment would
occur before any food crops would be present, and degradation would
prevent uptake by plants; thus, no residues are expected from use as a
soil treatment to sterilize the soil and kill pathogens in soils.
When used to treat plants directly, the Agency anticipates that PAA
will be applied to the plant at concentrations that will not cause
damage to the plant. At such concentrations, the Agency expects PAA to
degrade within 24 hours into AA, oxygen, and water because PAA begins
to degrade immediately upon contact with organic matter. Therefore, the
Agency has determined that there will be little to no exposure to PAA
from direct treatment of plants.
2. Drinking water exposure. The Agency expects there to be little
to no exposure of humans to PAA and its degradates in drinking water
since PAA degrades quickly in water, i.e., within 24 hours, especially
water bodies with neutral or alkaline pH levels, into AA, oxygen, and
water. In the event that residues of the degradates are present, the
levels of the degradates do not present a risk concern based on the
foreseeable rates at which PAA is likely to be applied.
B. Other Non-Occupational Exposure
Non-occupational exposure is not expected since PAA rapidly
degrades and is non-persistent in the environment.
V. 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, EPA 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 peroxyacetic acid to share a common mechanism of
toxicity with any other substances, and peroxyacetic acid does not
appear to produce a toxic metabolite as its mode of action against the
target pests. For the purposes of this tolerance action, therefore, EPA
has assumed that peroxyacetic acid does 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.
VI. Determination of Safety for U.S. Population, Infants and Children
1. U.S. population. Based on the lack of exposure to much, if any,
PAA and its metabolites and degradates, including HP and AA, the Agency
has concluded that there is reasonable certainty that no harm will
result to the general U.S. population, including infants and children,
from aggregate exposure to PAA and its metabolites and degradates,
including HP and AA. This includes all anticipated dietary exposures
and all other exposures for which there is reliable information.
2. Infants and children. FFDCA section 408(b)(2)(C) provides that
EPA shall apply an additional tenfold margin of exposure (MOE) for
infants and children in the case of threshold effects to account for
prenatal and postnatal toxicity and the completeness of the data base
on toxicity and exposure, unless EPA determines that a different MOE
will be safe for children. MOEs, which are often referred to as
uncertainty (safety) factors, are incorporated into EPA risk
assessments either directly, or through the use of a MOE analysis or by
using uncertainty factors in calculating a dose level that poses no
appreciable risk. Because there are no threshold effects of concern to
infants, children, and adults from PAA and its metabolites or
degradates, including HP and AA, the Agency concludes that the
additional MOE is not necessary to protect infants and children and
that removing the FQPA safety factor will be safe for infants and
children.
VII. Other Considerations
A. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
EPA is establishing an exemption from the requirement of a tolerance
without any numerical limitation.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and
Agriculture Organization/World Health Organization food standards
program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established a MRL for peroxyacetic acid.
VIII. Conclusions
EPA concludes that there is a reasonable certainty that no harm
will result to the U.S. population, including infants and children,
from aggregate exposure to residues of peroxyacetic acid and its
metabolites and degradates, including AA and HP. Therefore, the
existing tolerance exemption for PAA is amended to establish a
tolerance exemption for residues of the biochemical pesticide,
peroxyacetic acid, in or on all food commodities, when used in
accordance with good agricultural practices.

X. Statutory and Executive Order Reviews
This final rule establishes a tolerance exemption under section
408(d) of FFDCA in response to a petition submitted to EPA. 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
[[Page 11969]]
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 tolerance
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. As a result, this
action does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, EPA 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, EPA has determined that
Executive Order 13132, entitled Federalism (64 FR 43255, August 10,
1999), and Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 9,
2000), do not apply to this final rule. In addition, this final rule
does not impose any enforceable duty or contain any unfunded mandate as
described under Title II of the Unfunded Mandates Reform Act of 1995
(UMRA) (Pub. L. 104-4).
This action does not involve any technical standards that would
require EPA 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).
XI. 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).
