II. Background and Statutory Findings
In the Federal Register of April 7,
2010 (75 FR 17715) (FRL–8810–7), EPA
issued a notice pursuant to section
408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide tolerance petition (PP 9G7656)
by Fine Agrochemicals, Ltd., c/o SciReg,
Inc., 12733 Director’s Loop,
Woodbridge, VA, 22192. The petition
requested that 40 CFR part 180 be
amended by establishing a temporary
exemption from the requirement of a
tolerance for residues of
prohydrojasmon, propyl-3-oxo-2pentylcyclo-pentylacetate, (PDJ), for its
use in accordance with the terms of
Experimental Use Permit (EUP) No.
62097-EUP-R. This notice referenced a
summary of the petition prepared by the
petitioner Fine Agrochemicals, Ltd., c/o
SciReg, Inc., 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 and to ‘‘ensure
that there is a reasonable certainty that
no harm will result to infants and
children from aggregate exposure to the
pesticide chemical residue....’’
Additionally, section 408(b)(2)(D) of
FFDCA requires that the Agency
consider ‘‘available information
concerning the cumulative effects of a
particular pesticide’s residues’’ and
‘‘other substances that have a common
mechanism of toxicity.’’
PO 00000
Frm 00079

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.
PDJ is a synthetically made plant
growth regulator which is both
structurally similar and functionally
identical to jasmonic acid (JA), a
naturally occurring plant regulator
present in all vascular (higher) plants.
The jasomates, of which JA is a member,
is a group of plant hormones involved
in multiple stages of plant development
and defense, including the ability to
stimulate fruit ripening (Creelman and
Mullet, et al., 1995). The highest levels
of naturally occurring JA are found in
actively growing plant tissues such as
leaves, flowers, and developing fruit
(Creelman and Mullet, et al., 1995;
Mason et al., 1992), thus JA has always
been a natural component of diets
containing plant materials. To date,
there have been no reported toxic effects
associated with the consumption of JA
in fruits and vegetables.
PDJ, a synthetic version of JA, is
expected to behave in the same manner
and have the same low toxicity profile
as JA since it is structurally similar and
functionally identical to naturally
occurring JA. Studies submitted by the
applicant and reviewed by EPA indicate
that PDJ is not acutely toxic. No toxic
endpoints were established, and no
significant toxicological effects were
observed in any of the acute toxicity
studies. In addition, studies submitted
indicate that PDJ is not genotoxic, has
no subchronic toxic effects, and is not
a developmental toxicant. Summaries of
the toxicological data submitted in
support of this temporary exemption
from the requirement of a tolerance
follow.
A. Acute Toxicity
Acute toxicity studies on the
technical grade active ingredient (TGAI)
for PDJ, containing 97.98% PDJ, confirm
E:\FR\FM\18AUR1.SGM
18AUR1
50924
Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Rules and Regulations
erowe on DSK5CLS3C1PROD with RULES
a low toxicity profile. The acute toxicity
data show virtual nontoxicity for all
routes of exposure and it can be
concluded that any dietary risks
associated with this plant regulator
would be negligible.
1. The acute oral median lethal dose
(LD50) in rats was greater than 5,000
milligrams per kilogram (mg/kg)
bodyweight. There were no observed
toxicological effects on the test subjects
in the acute oral study submitted (MRID
No. 47927825). PDJ is classified as
Toxicity Category IV for acute oral
toxicity.
2. The acute dermal LD50 in rats was
greater than 2,000 mg/kg bodyweight
(MRID 47927826). PDJ is classified as
Toxicity Category III for acute dermal
toxicity.
3. The acute inhalation median lethal
concentration (LC50) was greater than
2.8 milligrams per liter (mg/L) in rats
and showed no significant inhalation
toxicity (MRID 47927827). PDJ is
classified as Toxicity Category IV for
acute inhalation toxicity.
4. A primary eye irritation study on
rabbits indicates that PDJ is minimally
irritating to the eye (MRID 47927828).
PDJ is classified as Toxicity Category IV
for primary eye irritation.
5. A skin irritation study on rabbits
indicates that PDJ is not irritating to the
skin (MRID 47927829). PDJ is classified
as Toxicity Category IV for primary skin
irritation.
6. Data indicate that PDJ is not a
dermal sensitizer (MRID 47927830).
B. Mutagenicity
Two mutagenicity studies, using the
TGAI of PDJ (97.98% PDJ) as the test
substance, were performed. These
studies are sufficient to confirm that
there are no expected dietary or nonoccupational risks of mutagenicity with
regard to new food uses.
1. A Bacterial Reverse Gene Mutation
Test (MRID No. 47927833) investigating
doses of test substance up to those that
were cytotoxic, both with and without
metabolic S9 activation, found no
incidences of a 2-fold or greater increase
in the number of revertants compared to
the corresponding solvent control.
Therefore, PDJ is considered to be nonmutagenic under the conditions of this
assay.
2. An in vitro Mammalian Cell
Chromosome Aberration Test (MRID No.
47927834) tested PDJ genotoxicity on
Chinese hamster lung cells (CHL/IU) up
to the cytotoxic dose level (80
micrograms per milliliter [μg/mL], based
on reduced mitotic activity) without S9
activation, and up to the limit
concentration of 5,000 μg/mL with S9
activation. None of the test substance
VerDate Mar<15>2010
15:12 Aug 17, 2010
Jkt 220001
concentrations induced a significant
increase in the incidence of cells with
chromosomal abnormalities, either in
the absence or presence of S9 activation.
In both experiments, the fraction of cells
with chromosomal aberrations was
below 5%, indicating a negative
response of the test substance. There
was also no indication of a doseresponse effect either with or without
metabolic activation. All of the negative,
solvent, and positive controls gave
appropriate responses. Therefore, under
the conditions of this assay, PDJ is
considered to be non-mutagenic and
does not cause chromosome aberrations.
C. Subchronic Toxicity
In a subchronic toxicity study using
the TGAI of PDJ (97.98% PDJ) as the test
substance, no clinically or
toxicologically significant effects were
found in any treatment group (MRID
47927831). Therefore, the no observed
adverse effect level (NOAEL) for PDJ has
been established as the highest test
substance dose, 10,000 parts per million
(ppm) (equivalent to 566 mg/kg bw/day
for male test animals and 587 mg/kg bw/
day for female test animals). A lowest
observed adverse effect level (LOAEL)
was not established, suggesting that the
test animals could have tolerated a
higher dose. In sum, the data submitted
to the Agency indicate that PDJ has no
subchronic toxicological effect.
D. Developmental Toxicity
In a developmental toxicity study,
using the TGAI of PDJ (97.98% PDJ) as
the test substance (MRID 47927832),
there were no treatment-related effects
found at necropsy in maternal animals
nor were there effects on copra lutei,
number of implantations, sex ratio, fetal
body weight, or preimplantation
embryonic mortality. The Agency does
not consider the transient decrease in
body weight or food intake as adverse
and establishes the NOAEL for this
study as 500 mg/kg bw/day. A LOAEL
was not identified for maternal effects,
suggesting that the test animals could
have tolerated a higher dose. No
treatment-related developmental effects
were found on external examination of
the fetuses. Visceral examination
showed a slight increase in the
incidence of thymic remnants; however,
the increase was within the range of the
performing laboratories historical
control data. Therefore, the Agency does
not consider this a treatment-related
effect. There was also a slight increase
in the incidence of a 14th rib, a common
variation in this strain of rat and is
therefore not considered an adverse
effect. It was not accompanied by an
increased incidence of abnormal
PO 00000
Frm 00080
Fmt 4700
Sfmt 4700
embryos, either on external, skeletal, or
visceral examination, and did not
appear at a higher than normal rate.
Based on the study results, the
developmental effects NOAEL for the
study is the highest dose tested 500 mg/
kg bw/day. A LOAEL was not identified
for developmental effects, suggesting
that the test animals could have
tolerated a higher dose. In sum, the data
submitted to the Agency indicate that
PDJ is not a developmental toxicant.
IV. Aggregate Exposures
In examining aggregate exposure,
section 408 of FFDCA directs EPA to
consider available information
concerning exposures from the pesticide
residue in food and all other nonoccupational exposures, including
drinking water from ground water or
surface water and exposure through
pesticide use in gardens, lawns, or
buildings (residential and other indoor
uses).
A. Dietary Exposure
Dietary exposure to the residues of
PDJ is expected to be insignificant, even
in the event of exposure. Based on
subchronic toxicity data submitted in
support of this petition, the Agency has
calculated the possibility of dietary
exposure and concludes that in a worst
case scenario, such as no degradation,
PDJ residues consumed by a 70 kg
person are four orders of magnitude
below the NOAEL that was calculated
for this compound (EPA, 2010).
Moreover, based on the fate and
distribution data (absorption/
desorption, hydrolysis,
photodegredation in water, and aerobic
soil metabolism) submitted by the
applicant and reviewed by EPA, PDJ,
when applied to plant material such as
fruit and foliage, is expected to degrade
rapidly, with calculated environmental
concentrations ranging from 0.77 to 0.06
ppm on the day of application and
declining to 0.0 by two days post
application. In addition, these studies
indicate that PDJ is relatively unstable
in the environment with an aerobic soil
half-life of 1.6 – 2.3 hours, and upon
consumption breaks down under gastric
condition with a half-life of 0.8 days.
1. Food. PDJ is structurally similar to
the naturally occurring plant growth
regulator JA. JA is naturally present in
fruits and vegetables at various levels,
generally not exceeding 10uM (2ppm),
and has always been a component of
any diet containing plant materials
(Creelman and Mullet, 1995; Mason et
al., 1992). Dietary exposure to residues
of PDJ via exposure to treated fruit or
foliage (e.g. apples) is not expected to
exist above background levels of
E:\FR\FM\18AUR1.SGM
18AUR1
Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Rules and Regulations
erowe on DSK5CLS3C1PROD with RULES
naturally occurring JA. The maximum
application rate of PDJ will be 0.009
pounds of active ingredient per acre (lbs
ai/A) or 200 parts per million active
ingredient per acre (ppm ai/A). Using
the Terrestrial Exposure Model (T-REX;
USEPA), the Agency calculated that, in
a theoretical application at the
maximum rate, residue levels of PDJ on
grasses, broadleaf foliage, fruits, pods,
and seeds will range from 0.77 to 0.06
ppm on the day of application and
decline to 0.0 ppm by 2 days post
application (EPA, 2010). Given PDJ’s
expected short-lived presence on
vegetation, no significant pesticidal
residues are anticipated for harvested
foods. Furthermore, PDJ is relatively
unstable in the environment with an
aerobic soil half-life of 1.6 - 2.3 hours,
and upon consumption breaks down
under gastric condition with a half-life
of 0.8 days.
2. Drinking water exposure. Exposure
of humans to PDJ in drinking water is
unlikely since products are labeled for
application directly to terrestrial plants
and because data demonstrate a soil
half-life for this chemical from 1.6-2.3
hours, as well as rapid degradation in
water (EPA, 2010). Specifically, PDJ is
not to be applied directly to water or to
areas where surface water is present. In
addition, the Agency estimated
environmental concentrations to an
aquatic site from PDJ runoff (spray to
apple trees) using the GENeric
Estimated Environmental Concentration
model (GENEEC; EPA, 2001). The
expected concentrations in surface
water are well below (6 to 7 orders of
magnitude) the maximum doses used in
laboratory testing, where no toxic effects
were seen (e.g. Acute Oral Toxicity LD50
> 5,000 mg/kg; Developmental Toxicity
NOAEL > 500 mg/kg).
B. Other Non-Occupational Exposure
Non-occupational exposure is not
expected because PDJ is not approved
for residential uses. The active
ingredient is applied directly to
commodities and degrades rapidly.
1. Dermal exposure. Nonoccupational dermal exposures to PDJ
are expected to be negligible because of
its directed agricultural use as a plant
growth regulator applied to red apple
varieties pre-harvest. Any dermal
exposure associated with this
experimental use permit is expected to
be occupational in nature.
2. Inhalation exposure. Nonoccupational inhalation exposures are
not expected to result from the
agricultural uses of PDJ. Any inhalation
exposure associated with this
experimental use permit is expected to
be occupational in nature.
VerDate Mar<15>2010
15:12 Aug 17, 2010
Jkt 220001
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, 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 PDJ to share a
common mechanism of toxicity with
any other substances, and PDJ does not
appear to produce a toxic metabolite
produced by other substances. For the
purposes of this tolerance action,
therefore, EPA has assumed that PDJ
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 website at https://
www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S.
Population, Infants and Children
FFDCA section 408(b)(2)(C) provides
that EPA shall assess the available
information about consumption patterns
among infants and children, special
susceptibility of infants and children to
pesticide chemical residues, and the
cumulative effects on infants and
children of the residues and other
substances with a common mechanism
of toxicity. In addition, FFDCA section
408(b)(2)(C) provides that EPA shall
apply an additional tenfold margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database unless
EPA determines that a different margin
of safety will be safe for infants and
children. Margins of exposure (safety),
which are often referred to as
uncertainty factors, are incorporated
into EPA risk assessments either
directly or through the use of a margin
of exposure analysis, or by using
uncertainty (safety) factors in
calculating a dose level that poses no
appreciable risk.
The acute, subchronic, and
developmental toxicity data discussed
in Unit III.B. indicate that PDJ has
negligible toxicity. In addition, PDJ is
structurally similar to jasmonic acid,
which is ubiquitous in nature and
present in all fruits and vegetables and
for which there is no reported history of
toxicological incident. Furthermore,
based on subchronic toxicity data
submitted in support of this petition,
the Agency has calculated the
PO 00000
Frm 00081
Fmt 4700
Sfmt 4700
50925
possibility of dietary exposure and
concludes that in a worst case scenario,
such as no degradation, the PDJ residues
consumed by a 70 kg person are four
orders of magnitude below the NOAEL
that was calculated for this compound
(EPA, 2010). Therefore, EPA concludes
that there is a reasonable certainty that
no harm will result to the United States
population, including infants and
children, from aggregate exposure to the
residues of PDJ. This includes all
anticipated dietary exposures and all
other exposures for which there is
reliable information. The Agency has
arrived at this conclusion because the
data and information available on PDJ
do not demonstrate toxic potential to
mammals. Thus, there are no threshold
effects of concern and, as a result, an
additional margin of safety is not
necessary.
VII. Other Considerations
A. Analytical Enforcement Methodology
Through this action, the Agency
proposes a temporary exemption from
the requirement of a tolerance of PDJ
when used on red apple varieties
without any numerical limitations for
residues. The Agency has determined
that residues resulting from PDJ use as
a plant growth regulator are unlikely,
and that there are no significant toxicity
concerns even in the event that residues
of this active ingredient are present. As
a result, the Agency has concluded that
an analytical method is not required for
enforcement purposes for PDJ.
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 PDJ.

X. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled Regulatory
Planning and Review (58 FR 51735,
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order
12898, entitled Federal Actions to
Address Environmental Justice in
Minority Populations and Low-Income
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, such as
the 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.
VerDate Mar<15>2010
15:12 Aug 17, 2010
Jkt 220001
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
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).

II. Background and Statutory Findings
In the Federal Register of April 7, 2010 (75 FR 17715) (FRL-8810-
7), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance
petition (PP 9G7656) by Fine Agrochemicals, Ltd., c/o SciReg, Inc.,
12733 Director's Loop, Woodbridge, VA, 22192. The petition requested
that 40 CFR part 180 be amended by establishing a temporary exemption
from the requirement of a tolerance for residues of prohydrojasmon,
propyl-3-oxo-2-pentylcyclo-pentylacetate, (PDJ), for its use in
accordance with the terms of Experimental Use Permit (EUP) No. 62097-
EUP-R. This notice referenced a summary of the petition prepared by the
petitioner Fine Agrochemicals, Ltd., c/o SciReg, Inc., 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 and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical
residue....'' Additionally, section 408(b)(2)(D) of FFDCA requires that
the Agency consider ``available information concerning the cumulative
effects of a particular pesticide's residues'' and ``other substances
that have a common mechanism of toxicity.''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. First, 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.
PDJ is a synthetically made plant growth regulator which is both
structurally similar and functionally identical to jasmonic acid (JA),
a naturally occurring plant regulator present in all vascular (higher)
plants. The jasomates, of which JA is a member, is a group of plant
hormones involved in multiple stages of plant development and defense,
including the ability to stimulate fruit ripening (Creelman and Mullet,
et al., 1995). The highest levels of naturally occurring JA are found
in actively growing plant tissues such as leaves, flowers, and
developing fruit (Creelman and Mullet, et al., 1995; Mason et al.,
1992), thus JA has always been a natural component of diets containing
plant materials. To date, there have been no reported toxic effects
associated with the consumption of JA in fruits and vegetables.
PDJ, a synthetic version of JA, is expected to behave in the same
manner and have the same low toxicity profile as JA since it is
structurally similar and functionally identical to naturally occurring
JA. Studies submitted by the applicant and reviewed by EPA indicate
that PDJ is not acutely toxic. No toxic endpoints were established, and
no significant toxicological effects were observed in any of the acute
toxicity studies. In addition, studies submitted indicate that PDJ is
not genotoxic, has no subchronic toxic effects, and is not a
developmental toxicant. Summaries of the toxicological data submitted
in support of this temporary exemption from the requirement of a
tolerance follow.
A. Acute Toxicity
Acute toxicity studies on the technical grade active ingredient
(TGAI) for PDJ, containing 97.98% PDJ, confirm
[[Page 50924]]
a low toxicity profile. The acute toxicity data show virtual
nontoxicity for all routes of exposure and it can be concluded that any
dietary risks associated with this plant regulator would be negligible.
1. The acute oral median lethal dose (LD50) in rats was
greater than 5,000 milligrams per kilogram (mg/kg) bodyweight. There
were no observed toxicological effects on the test subjects in the
acute oral study submitted (MRID No. 47927825). PDJ is classified as
Toxicity Category IV for acute oral toxicity.
2. The acute dermal LD50 in rats was greater than 2,000
mg/kg bodyweight (MRID 47927826). PDJ is classified as Toxicity
Category III for acute dermal toxicity.
3. The acute inhalation median lethal concentration
(LC50) was greater than 2.8 milligrams per liter (mg/L) in
rats and showed no significant inhalation toxicity (MRID 47927827). PDJ
is classified as Toxicity Category IV for acute inhalation toxicity.
4. A primary eye irritation study on rabbits indicates that PDJ is
minimally irritating to the eye (MRID 47927828). PDJ is classified as
Toxicity Category IV for primary eye irritation.
5. A skin irritation study on rabbits indicates that PDJ is not
irritating to the skin (MRID 47927829). PDJ is classified as Toxicity
Category IV for primary skin irritation.
6. Data indicate that PDJ is not a dermal sensitizer (MRID
47927830).
B. Mutagenicity
Two mutagenicity studies, using the TGAI of PDJ (97.98% PDJ) as the
test substance, were performed. These studies are sufficient to confirm
that there are no expected dietary or non-occupational risks of
mutagenicity with regard to new food uses.
1. A Bacterial Reverse Gene Mutation Test (MRID No. 47927833)
investigating doses of test substance up to those that were cytotoxic,
both with and without metabolic S9 activation, found no incidences of a
2-fold or greater increase in the number of revertants compared to the
corresponding solvent control. Therefore, PDJ is considered to be non-
mutagenic under the conditions of this assay.
2. An in vitro Mammalian Cell Chromosome Aberration Test (MRID No.
47927834) tested PDJ genotoxicity on Chinese hamster lung cells (CHL/
IU) up to the cytotoxic dose level (80 micrograms per milliliter
[[micro]g/mL], based on reduced mitotic activity) without S9
activation, and up to the limit concentration of 5,000 [micro]g/mL with
S9 activation. None of the test substance concentrations induced a
significant increase in the incidence of cells with chromosomal
abnormalities, either in the absence or presence of S9 activation. In
both experiments, the fraction of cells with chromosomal aberrations
was below 5%, indicating a negative response of the test substance.
There was also no indication of a dose-response effect either with or
without metabolic activation. All of the negative, solvent, and
positive controls gave appropriate responses. Therefore, under the
conditions of this assay, PDJ is considered to be non-mutagenic and
does not cause chromosome aberrations.
C. Subchronic Toxicity
In a subchronic toxicity study using the TGAI of PDJ (97.98% PDJ)
as the test substance, no clinically or toxicologically significant
effects were found in any treatment group (MRID 47927831). Therefore,
the no observed adverse effect level (NOAEL) for PDJ has been
established as the highest test substance dose, 10,000 parts per
million (ppm) (equivalent to 566 mg/kg bw/day for male test animals and
587 mg/kg bw/day for female test animals). A lowest observed adverse
effect level (LOAEL) was not established, suggesting that the test
animals could have tolerated a higher dose. In sum, the data submitted
to the Agency indicate that PDJ has no subchronic toxicological effect.
D. Developmental Toxicity
In a developmental toxicity study, using the TGAI of PDJ (97.98%
PDJ) as the test substance (MRID 47927832), there were no treatment-
related effects found at necropsy in maternal animals nor were there
effects on copra lutei, number of implantations, sex ratio, fetal body
weight, or preimplantation embryonic mortality. The Agency does not
consider the transient decrease in body weight or food intake as
adverse and establishes the NOAEL for this study as 500 mg/kg bw/day. A
LOAEL was not identified for maternal effects, suggesting that the test
animals could have tolerated a higher dose. No treatment-related
developmental effects were found on external examination of the
fetuses. Visceral examination showed a slight increase in the incidence
of thymic remnants; however, the increase was within the range of the
performing laboratories historical control data. Therefore, the Agency
does not consider this a treatment-related effect. There was also a
slight increase in the incidence of a 14th rib, a common variation in
this strain of rat and is therefore not considered an adverse effect.
It was not accompanied by an increased incidence of abnormal embryos,
either on external, skeletal, or visceral examination, and did not
appear at a higher than normal rate. Based on the study results, the
developmental effects NOAEL for the study is the highest dose tested
500 mg/kg bw/day. A LOAEL was not identified for developmental effects,
suggesting that the test animals could have tolerated a higher dose. In
sum, the data submitted to the Agency indicate that PDJ is not a
developmental toxicant.
IV. Aggregate Exposures
In examining aggregate exposure, section 408 of FFDCA directs EPA
to consider available information concerning exposures from the
pesticide residue in food and all other non-occupational exposures,
including drinking water from ground water or surface water and
exposure through pesticide use in gardens, lawns, or buildings
(residential and other indoor uses).
A. Dietary Exposure
Dietary exposure to the residues of PDJ is expected to be
insignificant, even in the event of exposure. Based on subchronic
toxicity data submitted in support of this petition, the Agency has
calculated the possibility of dietary exposure and concludes that in a
worst case scenario, such as no degradation, PDJ residues consumed by a
70 kg person are four orders of magnitude below the NOAEL that was
calculated for this compound (EPA, 2010). Moreover, based on the fate
and distribution data (absorption/desorption, hydrolysis,
photodegredation in water, and aerobic soil metabolism) submitted by
the applicant and reviewed by EPA, PDJ, when applied to plant material
such as fruit and foliage, is expected to degrade rapidly, with
calculated environmental concentrations ranging from 0.77 to 0.06 ppm
on the day of application and declining to 0.0 by two days post
application. In addition, these studies indicate that PDJ is relatively
unstable in the environment with an aerobic soil half-life of 1.6 - 2.3
hours, and upon consumption breaks down under gastric condition with a
half-life of 0.8 days.
1. Food. PDJ is structurally similar to the naturally occurring
plant growth regulator JA. JA is naturally present in fruits and
vegetables at various levels, generally not exceeding 10uM (2ppm), and
has always been a component of any diet containing plant materials
(Creelman and Mullet, 1995; Mason et al., 1992). Dietary exposure to
residues of PDJ via exposure to treated fruit or foliage (e.g. apples)
is not expected to exist above background levels of
[[Page 50925]]
naturally occurring JA. The maximum application rate of PDJ will be
0.009 pounds of active ingredient per acre (lbs ai/A) or 200 parts per
million active ingredient per acre (ppm ai/A). Using the Terrestrial
Exposure Model (T-REX; USEPA), the Agency calculated that, in a
theoretical application at the maximum rate, residue levels of PDJ on
grasses, broadleaf foliage, fruits, pods, and seeds will range from
0.77 to 0.06 ppm on the day of application and decline to 0.0 ppm by 2
days post application (EPA, 2010). Given PDJ's expected short-lived
presence on vegetation, no significant pesticidal residues are
anticipated for harvested foods. Furthermore, PDJ is relatively
unstable in the environment with an aerobic soil half-life of 1.6 - 2.3
hours, and upon consumption breaks down under gastric condition with a
half-life of 0.8 days.
2. Drinking water exposure. Exposure of humans to PDJ in drinking
water is unlikely since products are labeled for application directly
to terrestrial plants and because data demonstrate a soil half-life for
this chemical from 1.6-2.3 hours, as well as rapid degradation in water
(EPA, 2010). Specifically, PDJ is not to be applied directly to water
or to areas where surface water is present. In addition, the Agency
estimated environmental concentrations to an aquatic site from PDJ
runoff (spray to apple trees) using the GENeric Estimated Environmental
Concentration model (GENEEC; EPA, 2001). The expected concentrations in
surface water are well below (6 to 7 orders of magnitude) the maximum
doses used in laboratory testing, where no toxic effects were seen
(e.g. Acute Oral Toxicity LD50 > 5,000 mg/kg; Developmental
Toxicity NOAEL > 500 mg/kg).
B. Other Non-Occupational Exposure
Non-occupational exposure is not expected because PDJ is not
approved for residential uses. The active ingredient is applied
directly to commodities and degrades rapidly.
1. Dermal exposure. Non-occupational dermal exposures to PDJ are
expected to be negligible because of its directed agricultural use as a
plant growth regulator applied to red apple varieties pre-harvest. Any
dermal exposure associated with this experimental use permit is
expected to be occupational in nature.
2. Inhalation exposure. Non-occupational inhalation exposures are
not expected to result from the agricultural uses of PDJ. Any
inhalation exposure associated with this experimental use permit is
expected to be occupational in nature.
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, 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 PDJ to share a common mechanism of toxicity with
any other substances, and PDJ does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that PDJ 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 website at https://www.epa.gov/pesticides/cumulative.
VI. Determination of Safety for U.S. Population, Infants and Children
FFDCA section 408(b)(2)(C) provides that EPA shall assess the
available information about consumption patterns among infants and
children, special susceptibility of infants and children to pesticide
chemical residues, and the cumulative effects on infants and children
of the residues and other substances with a common mechanism of
toxicity. In addition, FFDCA section 408(b)(2)(C) provides that EPA
shall apply an additional tenfold margin of safety for infants and
children in the case of threshold effects to account for prenatal and
postnatal toxicity and the completeness of the database unless EPA
determines that a different margin of safety will be safe for infants
and children. Margins of exposure (safety), which are often referred to
as uncertainty factors, are incorporated into EPA risk assessments
either directly or through the use of a margin of exposure analysis, or
by using uncertainty (safety) factors in calculating a dose level that
poses no appreciable risk.
The acute, subchronic, and developmental toxicity data discussed in
Unit III.B. indicate that PDJ has negligible toxicity. In addition, PDJ
is structurally similar to jasmonic acid, which is ubiquitous in nature
and present in all fruits and vegetables and for which there is no
reported history of toxicological incident. Furthermore, based on
subchronic toxicity data submitted in support of this petition, the
Agency has calculated the possibility of dietary exposure and concludes
that in a worst case scenario, such as no degradation, the PDJ residues
consumed by a 70 kg person are four orders of magnitude below the NOAEL
that was calculated for this compound (EPA, 2010). Therefore, EPA
concludes that there is a reasonable certainty that no harm will result
to the United States population, including infants and children, from
aggregate exposure to the residues of PDJ. This includes all
anticipated dietary exposures and all other exposures for which there
is reliable information. The Agency has arrived at this conclusion
because the data and information available on PDJ do not demonstrate
toxic potential to mammals. Thus, there are no threshold effects of
concern and, as a result, an additional margin of safety is not
necessary.
VII. Other Considerations
A. Analytical Enforcement Methodology
Through this action, the Agency proposes a temporary exemption
from the requirement of a tolerance of PDJ when used on red apple
varieties without any numerical limitations for residues. The Agency
has determined that residues resulting from PDJ use as a plant growth
regulator are unlikely, and that there are no significant toxicity
concerns even in the event that residues of this active ingredient are
present. As a result, the Agency has concluded that an analytical
method is not required for enforcement purposes for PDJ.
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 PDJ.

VIII. Conclusion
Therefore, a temporary exemption is established for residues of PDJ
when used on red apple varieties pre-harvest and in accordance with
good agricultural practices.

X. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
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).
