II. Petition for Tolerance
In the Federal Register of November
22, 2006 (71 FR 67571) (FRL–8102–2),
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 petition (PP 6E7003) by IR-4,
500 College Road East, Suite 201 W,
Princeton, NJ 08540. The petition
requested that 40 CFR 180.510 be
amended by establishing tolerances for
residues of the insecticide,
pyriproxyfen, 2-1-methyl-2-(4phenoxyphenoxy)ethoxypyridine, in or
on vegetable, root and tuber, group 1 at
0.15 part per million (ppm); vegetable,
leaves of root and tuber, group 2 at 2.0
ppm; vegetable, bulb, group 3, except
onion, dry bulb at 0.70 ppm; vegetable,
leafy, except brassica, group 4 at 2.0
ppm; vegetable, legume, group 6 at 0.2
ppm; vegetable, foliage of legume, group
7 at 2.0 ppm; caneberry, subgroup 13A
at 1.0 ppm; grain, cereal, group 15 at 1.1
ppm; grain, cereal, forage, fodder and
straw, group 16 at 1.1 ppm; animal feed,
nongrass, group 18 at 0.7 ppm for
forage, 2.0 for seed, and 1.1 for hay;
asparagus at 2.0 ppm; banana and
plantain at 0.2 ppm; cacao bean at 0.02
ppm; canola, seed at 0.20 ppm; coffee at
0.02 ppm; cranberry at 1.0 ppm; date at

sesame, seed at 0.02 ppm; sugarcane at
1.1 ppm; tea at 0.02 ppm; watercress at
2.0 ppm; and artichoke, globe at 2.0
ppm. That notice referenced a summary
of the petition prepared by Valent USA
Corporation, the registrant, which is
available to the public in the docket,
https://www.regulations.gov. One
comment was received on the notice of
filing. EPA’s response to comment is
discussed in Unit IV.C.
Based upon review of the data
supporting the petition, EPA has
determined that proposed tolerances for
vegetable, leaves of root, and tuber,
group 2; vegetable, leafy, except,
Brassica, group 4; vegetable, legume,
group 6; vegetable, foliage of legume,
group 7; artichoke, globe; asparagus;
kiwifruit; and watercress will not be
established at this time. Further, the
Agency is establishing the following
additional tolerances in conjunction
with the tolerances that were requested:
Beet, sugar, dried, pulp; potato,
granules/flakes; potato, chips; potato,
wet peel; rice, hulls; coffee, instant; and

0.15 ppm. EPA’s assessment of
exposures and risks associated with
establishing the tolerances follow.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of the FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide pyriproxyfen
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of the FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide pyriproxyfen 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 the FFDCA requires EPA
to give special consideration to
exposure of infants and children to the
pesticide pyriproxyfen 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 pyriproxyfen residue....’’
These provisions were added to the
FFDCA by the Food Quality Protection
Act (FQPA) of 1996.
Consistent with FFDCA section
408(b)(2)(D), and the factors specified in
section 408(b)(2)(D), 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
the petitioned-for tolerances for residues
of pyriproxyfen on animal feed,
nongrass, group 18, forage at 0.70 ppm;
animal feed, nongrass, group 18, hay at
1.1 ppm; animal feed, nongrass, group

A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its 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 pyriproxyfen as well as the noobserved-adverse-effect-level (NOAEL)
and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies
can be found at https://www.epa.gov/
fedrgstr/EPA-PEST/2003/May/Day-14/

B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, the toxicological level of concern
(LOC) is derived from the highest dose
at which no adverse effects are observed
(the NOAEL) in the toxicology study
identified as appropriate for use in risk
assessment. However, if a NOAEL
cannot be determined, the lowest dose
at which adverse effects of concern are
identified (the LOAEL) is sometimes
used for risk assessment. Uncertainty/
safety factors (UF) are used in
conjunction with the LOC to take into
account uncertainties inherent in the
extrapolation from laboratory animal
data to humans and in the variations in
sensitivity among members of the
human population as well as other
unknowns. Safety is assessed for acute
and chronic risks by comparing
aggregate exposure to the pesticide to
the acute population adjusted dose
(‘‘aPAD’’) and chronic population
adjusted dose (‘‘cPAD’’). The aPAD and
cPAD are calculated by dividing the
LOC by all applicable uncertainty/safety
factors. Short-, intermediate, and longterm risks are evaluated by comparing
aggregate exposure to the LOC to ensure
that the margin of exposure (‘‘MOE’’)
called for by the product of all
applicable uncertainty/safety factors is
not exceeded.
For non-threshold risks, the Agency
assumes that any amount of exposure
will lead to some degree of risk and
estimates risk in terms of the probability
of occurrence of additional adverse
cases. Generally, cancer risks are
considered non-threshold. For more

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to pyriproxyfen, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing pyriproxyfen tolerances in (40
CFR 180.510). EPA assessed dietary
exposures from pyriproxyfen in food as
follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
are performed for a food-use pesticide,
if a toxicological study has indicated the
possibility of an effect of concern
occurring as a result of a one-day or
single exposure. No such effects were
identified in the toxicological studies
for pyriproxyfen; therefore, a
quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the 1994–1996 and 1998
Nationwide Continuing Surveys of Food
Intake by Individuals (CSFII). As to
residue levels in food, EPA performed a
Tier 1 chronic analysis which assumed
100% crop treated (CT), default
processing factors, and tolerance level
residues for all commodities.
iii. Cancer. A cancer dietary risk
assessment was not performed because
no evidence of carcinogenicity has been
found for pyriproxyfen.
2. Dietary exposure from drinking
water. The Agency lacks sufficient
monitoring data to complete a
comprehensive dietary exposure
analysis and risk assessment for
pyriproxyfen in drinking water. Because
the Agency does not have
comprehensive monitoring data,
drinking water concentration estimates
are made by reliance on simulation or
modeling taking into account data on
the environmental fate characteristics of
pyriproxyfen. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www.epa.gov/
oppefed1/models/water/index.htm.

Based on EPA’s Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening
Concentration in Groundwater (SCIGROW) models, the estimated
environmental concentrations (EECs) of
pyriproxyfen for acute and chronic
exposures for surface water are
estimated to be 2.15 parts per billion
(ppb), and 0.40 ppb, respectively. The
EEC for chronic exposure is estimated to
be 0.006 ppb for groundwater. Both
models assumed a maximum seasonal
application rate of 0.11 lb ai/A, 3 times
per year (citrus and stone fruit).
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 0.40 ppb
was used to access the contribution to
drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Pyriproxyfen is the active ingredient
in many registered residential products
for flea and tick control (home
environment and pet treatments) as well
as products for ant and roach control
(indoor and outdoor applications).
Formulations include carpet powders,
foggers, aerosol sprays, liquids
(shampoos, sprays and pipettes for pet
treatments), granules, bait (indoor and
outdoor), and impregnated materials
(pet collars). Only a post-application
residential assessment was conducted as
the Agency did not select any short-term
dermal or inhalation endpoints.
Toddlers are anticipated to have the
highest exposures from treated home
environments and pets due to typical
hand-to-mouth behavior. EPA assessed
residential exposure using the following
assumptions:
• Short-term, intermediate-term, and
long-term toddler hand-to-mouth
exposures (consisting of petting treated
animals and touching treated carpets/
flooring).
• Long-term dermal exposures for
products with anticipated efficacy more
than 6 months (carpet powders and pet
collars).
• Combined treatment toddler
exposure scenarios as a result of
treatments to the home environment
and the pet in the same period (such as
carpet powder and pet shampoo
treatments). Episodic ingestion of
granules by toddlers is anticipated, but
an assessment for this scenario is not
included, since an acute dietary
endpoint was not selected.

4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of the FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
pyriproxyfen and any other substances
and pyriproxyfen does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that pyriproxyfen has 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.
D. Safety Factor for Infants and
Children
1. In general. Section 408 of FFDCA
provides that EPA shall apply an
additional (‘‘10X’’) 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 data base 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. In applying
this provision, EPA either retains the
default value of 10X when reliable data
do not support the choice of a different
factor, or, if reliable data are available,
EPA uses a different additional FQPA
safety factor value based on the use of
traditional uncertainty/safety factors
and/or special FQPA safety factors, as
appropriate.
2. Prenatal and postnatal sensitivity.
Based on the available data, there is no
quantitative and qualitative evidence of
increased susceptibility observed
following in utero pyriproxyfen
exposure to rats and rabbits or following
prenatal/postnatal exposure in the 2–
generation reproduction study.
3. Conclusion. EPA has determined
that reliable data show that it would be
safe for infants and children to reduce
the FQPA safety factor to 1X. That
decision is based on the following
findings:
E:\FR\FM\22AUR1.SGM
22AUR1
Federal Register / Vol. 72, No. 162 / Wednesday, August 22, 2007 / Rules and Regulations
yshivers on PROD1PC62 with RULES
i. The toxicity database for
pyriproxyfen is complete.
ii. There is no indication that
pyriproxyfen is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional uncertainty factors to account
for neurotoxicity.
iii. There is no evidence that
pyriproxyfen results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2–generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100% CT and
tolerance-level residues. Conservative
ground water and surface water
modeling estimates were used. Similarly
conservative Residential Standard
Operating Procedues (SOPs) were used
to assess post-application exposure to
children as well as incidental oral
exposure of toddlers. These assessments
will not underestimate the exposure and
risks posed by pyriproxyfen.
E. Aggregate Risks and Determination of
Safety
Safety is assessed for acute and
chronic risks by comparing aggregate
exposure to the pesticide to the aPAD
and cPAD. The aPAD and cPAD are
calculated by dividing the LOC by all
applicable uncertainty/safety factors.
For linear cancer risks, EPA calculates
the probability of additional cancer
cases given aggregate exposure. Shortterm, intermediate-term, and long-term
risks are evaluated by comparing
aggregate exposure to the LOC to ensure
that the MOE called for by the product
of all applicable uncertainty/safety
factors is not exceeded.
1. Acute risk. No such effects were
identified in the toxicological studies
for pyriproxyfen; therefore, a
quantitative acute risk assessment is
unnecessary.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that exposure to pyriproxyfen from food
and water will utilize 10% of the cPAD
for the population group children 1-2
years old. A long-term post-application
residential assessment was performed
for toddlers only since they are
anticipated to have the higher exposures
than adults from treated home
environments and pets due to their
behavior patterns. The total chronic
dietary and residential aggregate MOEs
range from 570 to 4,700.
3. Short-term and intermediate-term
risk. Short and intermediate-term
aggregate exposures take into account
VerDate Aug<31>2005
15:19 Aug 21, 2007
Jkt 211001
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Pyriproxyfen is currently registered for
use that could result in short-term and
intermediate-term residential exposures
and the Agency has determined that it
is appropriate to aggregate chronic food
and water for short-term and
intermediate-term exposures for
pyriproxyfen.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded that
food, water, and residential exposures
aggregated result in aggregate MOEs
range from 1,200 to 14,000 for children
1-2 years old, and females 13-49 years
old, respectively.
Using the exposure assumptions
described in this unit for intermediateterm exposures, EPA has concluded that
food, water, and residential exposures
aggregated result in aggregate MOEs
range from 430 to 4,700 for children 12 years old, and females 13-49 years old,
respectively.
4. Aggregate cancer risk for U.S.
population. Pyriproxyfen is classified as
a ‘‘Group E’’ chemical (negative for
carcinogenicity to humans). This
classification is based on the lack of
evidence of carcinogenicity in mice and
rats. EPA does not expect pyriproxyfen
to pose a cancer risk.
5. 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 pyriproxyfen
residues.
IV. Other Considerations

have a common mechanism of toxicity.’’
In this case, EPA did not assume that
this chemical has a common mechanism
of toxicity with other substances as the
chemical does not generate metabolites
produced also by other chemicals. For
specific information regarding EPA’s
approach to the use of common
mechanism of toxicity to evaluate the
cumulative effects of chemicals, please
refer to EPA’s website at https://
www.epa.gov/pesticides/cumulative/ to
see policy statements.
V. Conclusion
Following review of the residue data
submitted with the petition, EPA has
made several revisions to the petition’s
request for the establishment of
tolerances. First, due to absence of
confirmatory data, the Agency is not
establishing in this regulation the
tolerances proposed for vegetable,
leaves of root, and tuber, group 2;
vegetable, leafy, except, Brassica, group
4; vegetable, legume, group 6; vegetable,
foliage of legume, group 7; artichoke,
globe; asparagus; kiwifruit; and
watercress at this time. Second, EPA
determined that proposed tolerances for
various raw agricultural commodities
(beets, potatoes, rice, coffee, pineapples)
did not appropriately address residue
levels that could occur in foods
processed from those raw commodities.
Accordingly, relying on the theoretical
processing factors or processing factors
from the Agency’s pyriproxyfen
database, EPA is establishing tolerances
for the processed commodities of beet,
dry pulp; potato granules/flakes, chips,
and wet peel; rice, hulls; coffee, instant;
and pineapple processed residue.
Therefore, tolerances are established
for residues of pyriproxyfen, 2-[1methyl-2-(4phenoxyphenoxy)ethoxypyridine, in or
on the commodities listed in Unit III.
paragraph 2.
VI. 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 rule has
been exempted from review under
Executive Order 12866, this rule is not
subject to Executive Order 13211,
Actions Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,

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 6, 2000) do not apply
to this rule. In addition, This 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).
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
VII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of this final rule in the
Federal Register. This final rule is not
a ‘‘major rule’’ as defined by 5 U.S.C.
804(2).

II. Petition for Tolerance
In the Federal Register of November 22, 2006 (71 FR 67571) (FRL-
8102-2), 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 petition (PP
6E7003) by IR-4, 500 College Road East, Suite 201 W, Princeton, NJ
08540. The petition requested that 40 CFR 180.510 be amended by
establishing tolerances for residues of the insecticide, pyriproxyfen,
2-1-methyl-2-(4-phenoxyphenoxy)ethoxypyridine, in or on vegetable, root
and tuber, group 1 at 0.15 part per million (ppm); vegetable, leaves of
root and tuber, group 2 at 2.0 ppm; vegetable, bulb, group 3, except
onion, dry bulb at 0.70 ppm; vegetable, leafy, except brassica, group 4
at 2.0 ppm; vegetable, legume, group 6 at 0.2 ppm; vegetable, foliage
of legume, group 7 at 2.0 ppm; caneberry, subgroup 13A at 1.0 ppm;
grain, cereal, group 15 at 1.1 ppm; grain, cereal, forage, fodder and
straw, group 16 at 1.1 ppm; animal feed, nongrass, group 18 at 0.7 ppm
for forage, 2.0 for seed, and 1.1 for hay; asparagus at 2.0 ppm; banana
and plantain at 0.2 ppm; cacao bean at 0.02 ppm; canola, seed at 0.20
ppm; coffee at 0.02 ppm; cranberry at 1.0 ppm; date at 0.3 ppm; grass,
forage at 0.5 ppm; grass, hay at 1.0 ppm; kiwifruit at 0.1 ppm; pawpaw
at 1.0 ppm; peanut at 0.2 ppm; pineapple at 0.3 ppm; pomegranate at
0.20 ppm; safflower, seed at 0.2 ppm; sesame, seed at 0.02 ppm;
sugarcane at 1.1 ppm; tea at 0.02 ppm; watercress at 2.0 ppm; and
artichoke, globe at 2.0 ppm. That notice referenced a summary of the
petition prepared by Valent USA Corporation, the registrant, which is
available to the public in the docket, https://www.regulations.gov. One
comment was received on the notice of filing. EPA's response to comment
is discussed in Unit IV.C.
Based upon review of the data supporting the petition, EPA has
determined that proposed tolerances for vegetable, leaves of root, and
tuber, group 2; vegetable, leafy, except, Brassica, group 4; vegetable,
legume, group 6; vegetable, foliage of legume, group 7; artichoke,
globe; asparagus; kiwifruit; and watercress will not be established at
this time. Further, the Agency is establishing the following additional
tolerances in conjunction with the tolerances that were requested:
Beet, sugar, dried, pulp; potato, granules/flakes; potato, chips;
potato, wet peel; rice, hulls; coffee, instant; and pineapple, process
residue. The reason for these changes is explained in Unit IV.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide pyriproxyfen residue in or
on a food) only if EPA determines that the tolerance is ``safe.''
Section 408(b)(2)(A)(ii) of the FFDCA defines ``safe'' to mean that
``there is a reasonable certainty that no harm will result from
aggregate exposure to the pesticide pyriproxyfen 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 the FFDCA requires EPA to give
special consideration to exposure of infants and children to the
pesticide pyriproxyfen 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
pyriproxyfen residue....'' These provisions were added to the FFDCA by
the Food Quality Protection Act (FQPA) of 1996.
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in section 408(b)(2)(D), 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 the petitioned-for tolerances
for residues of pyriproxyfen on animal feed, nongrass, group 18, forage
at 0.70 ppm; animal feed, nongrass, group 18, hay at 1.1 ppm; animal
feed, nongrass, group 18, seed at 2.0 ppm; banana at 0.20 ppm; beet,
sugar, dried pulp at 3.0 ppm; cacao bean, dried at 0.02 ppm; caneberry,
subgroup 13-A at 1.0 ppm; canola, seed at 0.20 ppm; coffee, instant at
0.10 ppm; coffee, green bean at 0.02 ppm; cranberry at 1.0 ppm; date at
0.30 ppm; grain, cereal, group 15 at 1.1 ppm; grain, cereal, forage,
fodder and straw, group 16 at 1.1 ppm; pawpaw at 1.0 ppm; peanut at
0.20 ppm; pineapple at 0.30 ppm; pineapple, process residue at 1.1 ppm;
pomegranate at 0.20 ppm; potato, chips at 0.75 ppm; potato, granules/
flakes at 0.75 ppm; potato, wet peel at 0.75 ppm; rice, hulls at 5.5
ppm; safflower, seed at 0.20 ppm; sesame, seed at 0.02 ppm; sugarcane
at 1.1 ppm; tea at 0.02 ppm; vegetable, bulb, group 3, except onion,
bulb at 0.70 ppm; and vegetable, root and tuber, group 1 at 0.15 ppm.
EPA's assessment of exposures and risks associated with establishing
the tolerances follow.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
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 pyriproxyfen as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies can be found at https://
www.epa.gov/fedrgstr/EPA-PEST/2003/May/Day-14/p12022.htm in Federal
Register of May 14, 2003 (68 FR 25831) (FRL-7305-9).
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the toxicological level of concern (LOC) is derived
from the highest dose at which no adverse effects are observed (the
NOAEL) in the toxicology study identified as appropriate for use in
risk assessment. However, if a NOAEL cannot be determined, the lowest
dose at which adverse effects of concern are identified (the LOAEL) is
sometimes used for risk assessment. Uncertainty/safety factors (UF) are
used in conjunction with the LOC to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
risks by comparing aggregate exposure to the pesticide to the acute
population adjusted dose (``aPAD'') and chronic population adjusted
dose (``cPAD''). The aPAD and cPAD are calculated by dividing the LOC
by all applicable uncertainty/safety factors. Short-, intermediate, and
long-term risks are evaluated by comparing aggregate exposure to the
LOC to ensure that the margin of exposure (``MOE'') called for by the
product of all applicable uncertainty/safety factors is not exceeded.
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk and estimates risk in terms
of the probability of occurrence of additional adverse cases.
Generally, cancer risks are considered non-threshold. For more
information on the general principles

risk assessment process, see https://www.epa.gov/fedrgstr/EPA-PEST/1997/

IR-4 Tolerance Plan (Reduced Data Set Translations) on pages 9-10 in
Docket ID EPA-HQ-OPP-2006-0889.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to pyriproxyfen, EPA considered exposure under the petitioned-
for tolerances as well as all existing pyriproxyfen tolerances in (40
CFR 180.510). EPA assessed dietary exposures from pyriproxyfen in food
as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a one-day or single exposure. No such effects were
identified in the toxicological studies for pyriproxyfen; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the 1994-1996 and
1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII). As to residue levels in food, EPA performed a Tier 1 chronic
analysis which assumed 100% crop treated (CT), default processing
factors, and tolerance level residues for all commodities.
iii. Cancer. A cancer dietary risk assessment was not performed
because no evidence of carcinogenicity has been found for pyriproxyfen.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring data to complete a comprehensive dietary exposure
analysis and risk assessment for pyriproxyfen in drinking water.
Because the Agency does not have comprehensive monitoring data,
drinking water concentration estimates are made by reliance on
simulation or modeling taking into account data on the environmental
fate characteristics of pyriproxyfen. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on EPA's Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentration in Groundwater (SCI-
GROW) models, the estimated environmental concentrations (EECs) of
pyriproxyfen for acute and chronic exposures for surface water are
estimated to be 2.15 parts per billion (ppb), and 0.40 ppb,
respectively. The EEC for chronic exposure is estimated to be 0.006 ppb
for groundwater. Both models assumed a maximum seasonal application
rate of 0.11 lb ai/A, 3 times per year (citrus and stone fruit).
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 0.40 ppb was used to
access the contribution to drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
Pyriproxyfen is the active ingredient in many registered
residential products for flea and tick control (home environment and
pet treatments) as well as products for ant and roach control (indoor
and outdoor applications). Formulations include carpet powders,
foggers, aerosol sprays, liquids (shampoos, sprays and pipettes for pet
treatments), granules, bait (indoor and outdoor), and impregnated
materials (pet collars). Only a post-application residential assessment
was conducted as the Agency did not select any short-term dermal or
inhalation endpoints. Toddlers are anticipated to have the highest
exposures from treated home environments and pets due to typical hand-
to-mouth behavior. EPA assessed residential exposure using the
following assumptions:
Short-term, intermediate-term, and long-term toddler hand-
to-mouth exposures (consisting of petting treated animals and touching
treated carpets/flooring).
Long-term dermal exposures for products with anticipated
efficacy more than 6 months (carpet powders and pet collars).
Combined treatment toddler exposure scenarios as a result
of treatments to the home environment and the pet in the same period
(such as carpet powder and pet shampoo treatments). Episodic ingestion
of granules by toddlers is anticipated, but an assessment for this
scenario is not included, since an acute dietary endpoint was not
selected.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to pyriproxyfen and any other
substances and pyriproxyfen does not appear to produce a toxic
metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that pyriproxyfen has
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.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional (``10X'') 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 data base 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. In applying this provision, EPA either retains the default
value of 10X when reliable data do not support the choice of a
different factor, or, if reliable data are available, EPA uses a
different additional FQPA safety factor value based on the use of
traditional uncertainty/safety factors and/or special FQPA safety
factors, as appropriate.
2. Prenatal and postnatal sensitivity. Based on the available data,
there is no quantitative and qualitative evidence of increased
susceptibility observed following in utero pyriproxyfen exposure to
rats and rabbits or following prenatal/postnatal exposure in the 2-
generation reproduction study.
3. Conclusion. EPA has determined that reliable data show that it
would be safe for infants and children to reduce the FQPA safety factor
to 1X. That decision is based on the following findings:
[[Page 46917]]
i. The toxicity database for pyriproxyfen is complete.
ii. There is no indication that pyriproxyfen is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional uncertainty factors to account for neurotoxicity.
iii. There is no evidence that pyriproxyfen results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100% CT and tolerance-level residues. Conservative ground water and
surface water modeling estimates were used. Similarly conservative
Residential Standard Operating Procedues (SOPs) were used to assess
post-application exposure to children as well as incidental oral
exposure of toddlers. These assessments will not underestimate the
exposure and risks posed by pyriproxyfen.
E. Aggregate Risks and Determination of Safety
Safety is assessed for acute and chronic risks by comparing
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and
cPAD are calculated by dividing the LOC by all applicable uncertainty/
safety factors. For linear cancer risks, EPA calculates the probability
of additional cancer cases given aggregate exposure. Short-term,
intermediate-term, and long-term risks are evaluated by comparing
aggregate exposure to the LOC to ensure that the MOE called for by the
product of all applicable uncertainty/safety factors is not exceeded.
1. Acute risk. No such effects were identified in the toxicological
studies for pyriproxyfen; therefore, a quantitative acute risk
assessment is unnecessary.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
pyriproxyfen from food and water will utilize 10% of the cPAD for the
population group children 1-2 years old. A long-term post-application
residential assessment was performed for toddlers only since they are
anticipated to have the higher exposures than adults from treated home
environments and pets due to their behavior patterns. The total chronic
dietary and residential aggregate MOEs range from 570 to 4,700.
3. Short-term and intermediate-term risk. Short and intermediate-
term aggregate exposures take into account residential exposure plus
chronic exposure to food and water (considered to be a background
exposure level). Pyriproxyfen is currently registered for use that
could result in short-term and intermediate-term residential exposures
and the Agency has determined that it is appropriate to aggregate
chronic food and water for short-term and intermediate-term exposures
for pyriproxyfen.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded that food, water, and residential
exposures aggregated result in aggregate MOEs range from 1,200 to
14,000 for children 1-2 years old, and females 13-49 years old,
respectively.
Using the exposure assumptions described in this unit for
intermediate-term exposures, EPA has concluded that food, water, and
residential exposures aggregated result in aggregate MOEs range from
430 to 4,700 for children 1-2 years old, and females 13-49 years old,
respectively.
4. Aggregate cancer risk for U.S. population. Pyriproxyfen is
classified as a ``Group E'' chemical (negative for carcinogenicity to
humans). This classification is based on the lack of evidence of
carcinogenicity in mice and rats. EPA does not expect pyriproxyfen to
pose a cancer risk.
5. 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 pyriproxyfen residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography/nitrogen-
phosphorous detector (GC/NPD)) is available to enforce the tolerance
expression. The method may be requested from: Chief, Analytical
Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
There are currently no established Codex maximum residue limits
(MRLs) for pyriproxyfen.
C. Response to Comments
One comment was received by the Agency from a private citizen. The
comment applies to the use of ``available data'' concerning the
cumulative effects of the pesticide's residues and ``other substances
that have a common mechanism of toxicity.'' In this case, EPA did not
assume that this chemical has a common mechanism of toxicity with other
substances as the chemical does not generate metabolites produced also
by other chemicals. For specific information regarding EPA's approach
to the use of common mechanism of toxicity to evaluate the cumulative
effects of chemicals, please refer to EPA's website at https://
www.epa.gov/pesticides/cumulative/ to see policy statements.
V. Conclusion
Following review of the residue data submitted with the petition,
EPA has made several revisions to the petition's request for the
establishment of tolerances. First, due to absence of confirmatory
data, the Agency is not establishing in this regulation the tolerances
proposed for vegetable, leaves of root, and tuber, group 2; vegetable,
leafy, except, Brassica, group 4; vegetable, legume, group 6;
vegetable, foliage of legume, group 7; artichoke, globe; asparagus;
kiwifruit; and watercress at this time. Second, EPA determined that
proposed tolerances for various raw agricultural commodities (beets,
potatoes, rice, coffee, pineapples) did not appropriately address
residue levels that could occur in foods processed from those raw
commodities. Accordingly, relying on the theoretical processing factors
or processing factors from the Agency's pyriproxyfen database, EPA is
establishing tolerances for the processed commodities of beet, dry
pulp; potato granules/flakes, chips, and wet peel; rice, hulls; coffee,
instant; and pineapple processed residue.
Therefore, tolerances are established for residues of pyriproxyfen,
2-[1-methyl-2-(4-phenoxyphenoxy)ethoxypyridine, in or on the
commodities listed in Unit III. paragraph 2.
VI. 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 rule has been
exempted from review under Executive Order 12866, this rule is not
subject to Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355,
May 22, 2001) or Executive Order 13045,
[[Page 46918]]
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 6,
2000) do not apply to this rule. In addition, This rule does not impose
any enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law
104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
