technical standards (e.g., specifications
of materials, performance, design, or
operation; test methods; sampling
procedures; and related management
systems practices) that are developed or
adopted by voluntary consensus
standards bodies.
This proposed rule does not use
technical standards. Therefore, we did
not consider the use of voluntary
consensus standards.
Environment
We have analyzed this proposed rule
under Commandant Instruction
M16475.lD, which guides the Coast
Guard in complying with the National
Environmental Policy Act of 1969
(NEPA) (42 U.S.C. 4321–4370f), and
have concluded that there are no factors
in this case that would limit the use of
a categorical exclusion under section
2.B.2 of the Instruction. Therefore, this
proposed rule is categorically excluded,
under figure 2–1, paragraph (32)(e) of
the Instruction, from further
environmental documentation.

4550 New Linden Hill Road, Suite 501,
Wilmington, Delaware 19808.
A. Residue Chemistry
1. Plant metabolism. Fenpyroximate
and the Z-isomer are the residues of
concern for tolerance setting purposes
in crops. The metabolism of
fenpyroximate and its Z-isomer has
been studied, and is adequately
understood.
2. Analytical method. An enforcement
method has been developed which
involves extraction of fenpyroximate
from crops with acetone, filtration,
partitioning and cleanup, and analysis
PO 00000
Frm 00010
Fmt 4702
Sfmt 4702
by gas chromatography using a nitrogen/
phosphorous detector. This method
allows detection of residues at or above
the proposed tolerances. The method
has undergone independent laboratory
validation as required by PR Notices 88–
5 and 96–1.
3. Magnitude of residues. The
magnitude of residues for
fenpyroximate, and the Z-isomer are
adequately understood for the requested
tolerances.
B. Toxicological Profile
An extensive battery of toxicology
studies has been conducted with
fenpyroximate. 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.
An assessment of toxic effects caused by
fenpyroximate, including the
toxicological endpoints of concern, is
discussed in Unit III.A. and Unit III.B.
of the fenpyroximate final rule
published in the June 10, 2004 issue of
the Federal Register (69 FR 32457)
(FRL–7362–9).
1. Animal metabolism. The qualitative
nature of the residues of fenpyroximate,
Z-isomer, and acid metabolite in
animals is adequately understood.
2. Metabolite toxicology. No
toxicologically significant metabolites
were detected in plant or animal
metabolism studies for citrus, hops,
mint, and tree nuts.
3. Endocrine disruption. Chronic,
lifespan, and multi-generational
bioassays in mammals and acute and
subchronic studies on aquatic organisms
and wildlife did not reveal any
endocrine effects for fenpyroximate.
Any endocrine related effects would
have been detected in this
comprehensive series of required tests.
The probability of any such effect due
to agricultural uses of fenpyroximate is
negligible.
C. Aggregate Exposure
1. Dietary exposure. Tolerances have
been established (40 CFR 180.566) for
the combined residues of fenpyroximate
and its metabolites, in or on a variety of
raw agricultural commodities. Acute
and chronic dietary risk analyses were
conducted to estimate the potential
fenpyroximate and Z-isomer residues in
or on the following crops: Citrus orange,
citrus lemon, citrus grapefruit, citrus oil,
mint oil, hops, almond, pecans, and
pistachio, using modeling based on
USDA survey data.
i. Food. The acute dietary exposure
was based on the following
assumptions: Residues at tolerance
levels, 100% crop treated, and default
E:\FR\FM\10AUP1.SGM
10AUP1
Federal Register / Vol. 70, No. 153 / Wednesday, August 10, 2005 / Proposed Rules
processing factors for all proposed
commodities (Tier 1, 95th percentile
consumption). The chronic dietary
exposure was based on the following
assumptions: Residues at tolerance
levels, 100% crop treated, using dietary
exposure modeling, based on USDA
survey data.
ii. Drinking water. The Agency does
not have comprehensive monitoring
data; therefore, drinking water
concentration estimates are made by
reliance on simulation or modeling
taking into account data on the physical
characteristics of fenpyroximate. The
Agency uses the Food Quality
Protection Act (FQPA) Index Reservoir
Screening Tool (FIRST) or the Pesticide
Root Zone Model/Exposure Analysis
Modeling System (PRZM/EXAMS) to
produce estimates of pesticide
concentrations in an index reservoir to
predict surface water concentrations.
The Screen Concentrations in
Groundwater (SCI–GROW) model is
used to predict pesticide concentrations
in shallow ground water.
Since the models used are considered
to be screening tools in the risk
assessment process, the Agency does
not use estimated environmental
concentrations (EECs) from these
models to quantify drinking water
exposure and risk as a reference dose
(%RfD) or population adjusted dose
(%PAD). Instead, drinking water levels
of comparison (DWLOCs) are calculated
and used as a point of comparison
against the model estimates of a
pesticide’s concentration in water.
DWLOCs are theoretical upper limits on
a pesticide’s concentration in drinking
water in light of total aggregate exposure
to a pesticide in food, and from
residential uses.
The residue of concern in drinking
water was determined to be
fenpyroximate. There are no established
maximum contaminant levels or health
advisory levels for residues of
fenpyroximate in drinking water.
Laboratory and field data have
demonstrated that fenpyroximate is
immobile in soil and will not leach into
ground water. Other data show that
fenpyroximate is virtually insoluble in
water. As a result, EPA concluded that
residues reaching surface waters from
field runoff will quickly absorb to
sediment particles and be partitioned
from the water column.
Estimates of the contribution of the
petitioned crops to water concentrations
were derived. The acute and chronic
EEC’s in surface water calculated by
PRZM/EXAMS, Version 3.12, were 1.5
parts per billion (ppb), and 0.13 ppb
respectively. In ground water, using Tier
VerDate jul<14>2003
15:14 Aug 09, 2005
Jkt 205001
I SCI–GROW (Version 2.3), the
estimated EEC was 0.006 ppb.
2. 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). Fenpyroximate is not
registered for use on any sites that
would result in residential exposure.
D. Cumulative Effects
A determination has not been made
that fenpyroximate has a common
mechanism of toxicity with other
substances. Fenpyroximate does not
appear to produce a common toxic
metabolite with other substances. A
cumulative risk assessment was not
performed for this analysis. Section
408(b)(2)(D)(v) of FFDCA requires that
when considering whether to establish,
modify, or revoke a tolerance the
Agency considers, ‘‘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
fenpyroximate and any other
substances. Fenpyroximate does not
appear to produce a toxic metabolite
produced by other substances. For the
purposes of this tolerance action, EPA
has not assumed that fenpyroximate 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 the policy statements
released by EPA’s Office of Pesticide
Programs (OPP) concerning common
mechanism determinations and
procedures for cumulating effects from
substances found to have a common
mechanism on EPA’s Web site at
https://www.epa.gov/pesticides/
cumulative/.
E. Safety Determination
1. U.S. population—i. Acute risk. The
acute dietary acute Population Adjusted
Dose (aPAD) was set at 0.05 milligrams/
kilogram/day (mg/kg/day) for females
ages 13–49 years old based on a
developmental toxicity study in rats that
had an oral no observed adverse effect
level (NOAEL) of 5.0 mg/kg/day. The
resulting food exposure estimate for this
population subgroup was less than 1%
of the aPAD. The petitioned crops in
PO 00000
Frm 00011
Fmt 4702
Sfmt 4702
46447
addition to the registered crop uses
accounted for less than 6% of the aPAD.
The addition of these new uses results
in a DWLOC of approximately 1,400
ppb. Surface water concentration
estimates increase from 1.5 ppb to 1.6
ppb with the added crops. The aggregate
exposure will not exceed 100% of the
aPAD.
ii. Chronic risk. The chronic dietary
chronic Population Adjusted Dose
(cPAD) was determined to be 0.01 mg/
kg/day for the general population based
on an oral NOAEL of 0.97 mg/kg/day in
the 2-year rat chronic/carcinogenicity
study. The Agency determined that
exposure from currently registered crops
utilize 8% of the cPAD. The additional
new uses will result in a utilization of
10% of the cPAD. Using the exposure
assumptions previously described, EPA
has concluded that exposure to
fenpyroximate from food, including the
additional new uses, will utilize 10% of
the cPAD for the U.S. population, 21%
of the cPAD for all infants (<1 year old),
and 33% of the cPAD for children (1–
2 years old).
In addition, there is potential for
chronic dietary exposure to
fenpyroximate in drinking water. The
DWLOC for the general population,
infants (<1 year old) and children (1–6
years old) were 320 ppb, 82 ppb, and 71
ppb, respectively. Average yearly
drinking water concentration in surface
water was estimated at 0.13 ppb, and
0.006 ppb in ground water for both
registered and petitioned uses. After
calculating the DWLOCs and comparing
them to the EECs for surface and ground
water, the aggregate exposure will not
exceed 100% of the cPAD.
2. Infants and children. The Agency
confirmed the endpoint selection for
fenpyroximate and evaluated the
potential for increased susceptibility of
infants and children from exposure to
fenpyroximate (July 2003). Based on
toxicological considerations, the special
FQPA safety factor was set at 1X when
assessing acute and chronic dietary
exposures.
3. Aggregate cancer risk for U.S.
population. Fenpyroximate is classified
as not likely to be carcinogenic to
humans; therefore, an aggregate cancer
risk assessment was not performed.
4. Determination of safety. Based on
these risk assessments, EPA concluded
that there is a reasonable certainty that
no harm will result to the general
population, and to infants and children
from aggregate exposure to
fenpyroximate residues.

ACTION: Notification to the Secretaries of
Agriculture and Health and Human
Services.
AGENCY:
SUMMARY: This document notifies the
public that the Administrator of EPA
has forwarded to the Secretaries of
Agriculture and Health and Human
Services a draft proposed rule under
sections 21 and 25(a) of the Federal
Insecticide, Fungicide, and Rodenticide
Act (FIFRA). The draft proposed rule
will formalize and clarify EPA’s policies
on the use of intentional human
exposure studies under FIFRA and the
Federal Food Drug and Cosmetic Act
(FFDCA). The proposed rule would
establish stringent ethical protections
for human subjects in certain types of
research conducted or sponsored by
entities other than the Federal
government (i.e., ‘‘third-parties’’). These
protections are consistent with
requirements currently in place under
the Federal Policy for the Protection of
Human Subjects of Research (the
‘‘Common Rule’’), which has been
adopted by 17 Federal agencies. The
draft proposed rule is not available to
the public until after it has been signed
by EPA.
ADDRESSES: EPA has established a

not fully evaluated the sufficiency of the submitted data at this time
or whether the data support granting of the petition. Additional data
may be needed before EPA rules on the petition. This notice includes a
summary of the petition that was prepared by Nichino America, Inc.,
4550 New Linden Hill Road, Suite 501, Wilmington, Delaware 19808.
A. Residue Chemistry
1. Plant metabolism. Fenpyroximate and the Z-isomer are the
residues of concern for tolerance setting purposes in crops. The
metabolism of fenpyroximate and its Z-isomer has been studied, and is
adequately understood.
2. Analytical method. An enforcement method has been developed
which involves extraction of fenpyroximate from crops with acetone,
filtration, partitioning and cleanup, and analysis by gas
chromatography using a nitrogen/phosphorous detector. This method
allows detection of residues at or above the proposed tolerances. The
method has undergone independent laboratory validation as required by
PR Notices 88-5 and 96-1.
3. Magnitude of residues. The magnitude of residues for
fenpyroximate, and the Z-isomer are adequately understood for the
requested tolerances.
B. Toxicological Profile
An extensive battery of toxicology studies has been conducted with
fenpyroximate. 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. An assessment
of toxic effects caused by fenpyroximate, including the toxicological
endpoints of concern, is discussed in Unit III.A. and Unit III.B. of
the fenpyroximate final rule published in the June 10, 2004 issue of
the Federal Register (69 FR 32457) (FRL-7362-9).
1. Animal metabolism. The qualitative nature of the residues of
fenpyroximate, Z-isomer, and acid metabolite in animals is adequately
understood.
2. Metabolite toxicology. No toxicologically significant
metabolites were detected in plant or animal metabolism studies for
citrus, hops, mint, and tree nuts.
3. Endocrine disruption. Chronic, lifespan, and multi-generational
bioassays in mammals and acute and subchronic studies on aquatic
organisms and wildlife did not reveal any endocrine effects for
fenpyroximate. Any endocrine related effects would have been detected
in this comprehensive series of required tests. The probability of any
such effect due to agricultural uses of fenpyroximate is negligible.
C. Aggregate Exposure
1. Dietary exposure. Tolerances have been established (40 CFR
180.566) for the combined residues of fenpyroximate and its
metabolites, in or on a variety of raw agricultural commodities. Acute
and chronic dietary risk analyses were conducted to estimate the
potential fenpyroximate and Z-isomer residues in or on the following
crops: Citrus orange, citrus lemon, citrus grapefruit, citrus oil, mint
oil, hops, almond, pecans, and pistachio, using modeling based on USDA
survey data.
i. Food. The acute dietary exposure was based on the following
assumptions: Residues at tolerance levels, 100% crop treated, and
default
[[Page 46447]]
processing factors for all proposed commodities (Tier 1, 95th
percentile consumption). The chronic dietary exposure was based on the
following assumptions: Residues at tolerance levels, 100% crop treated,
using dietary exposure modeling, based on USDA survey data.
ii. Drinking water. The Agency does not have comprehensive
monitoring data; therefore, drinking water concentration estimates are
made by reliance on simulation or modeling taking into account data on
the physical characteristics of fenpyroximate. The Agency uses the Food
Quality Protection Act (FQPA) Index Reservoir Screening Tool (FIRST) or
the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/
EXAMS) to produce estimates of pesticide concentrations in an index
reservoir to predict surface water concentrations. The Screen
Concentrations in Groundwater (SCI-GROW) model is used to predict
pesticide concentrations in shallow ground water.
Since the models used are considered to be screening tools in the
risk assessment process, the Agency does not use estimated
environmental concentrations (EECs) from these models to quantify
drinking water exposure and risk as a reference dose (%RfD) or
population adjusted dose (%PAD). Instead, drinking water levels of
comparison (DWLOCs) are calculated and used as a point of comparison
against the model estimates of a pesticide's concentration in water.
DWLOCs are theoretical upper limits on a pesticide's concentration in
drinking water in light of total aggregate exposure to a pesticide in
food, and from residential uses.
The residue of concern in drinking water was determined to be
fenpyroximate. There are no established maximum contaminant levels or
health advisory levels for residues of fenpyroximate in drinking water.
Laboratory and field data have demonstrated that fenpyroximate is
immobile in soil and will not leach into ground water. Other data show
that fenpyroximate is virtually insoluble in water. As a result, EPA
concluded that residues reaching surface waters from field runoff will
quickly absorb to sediment particles and be partitioned from the water
column.
Estimates of the contribution of the petitioned crops to water
concentrations were derived. The acute and chronic EEC's in surface
water calculated by PRZM/EXAMS, Version 3.12, were 1.5 parts per
billion (ppb), and 0.13 ppb respectively. In ground water, using Tier I
SCI-GROW (Version 2.3), the estimated EEC was 0.006 ppb.
2. 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). Fenpyroximate is not registered for
use on any sites that would result in residential exposure.
D. Cumulative Effects
A determination has not been made that fenpyroximate has a common
mechanism of toxicity with other substances. Fenpyroximate does not
appear to produce a common toxic metabolite with other substances. A
cumulative risk assessment was not performed for this analysis. Section
408(b)(2)(D)(v) of FFDCA requires that when considering whether to
establish, modify, or revoke a tolerance the Agency considers,
``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
fenpyroximate and any other substances. Fenpyroximate does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, EPA has not assumed that
fenpyroximate 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 the policy statements released by EPA's
Office of Pesticide Programs (OPP) concerning common mechanism
determinations and procedures for cumulating effects from substances
found to have a common mechanism on EPA's Web site at https://
www.epa.gov/pesticides/cumulative/.
E. Safety Determination
1. U.S. population--i. Acute risk. The acute dietary acute
Population Adjusted Dose (aPAD) was set at 0.05 milligrams/kilogram/day
(mg/kg/day) for females ages 13-49 years old based on a developmental
toxicity study in rats that had an oral no observed adverse effect
level (NOAEL) of 5.0 mg/kg/day. The resulting food exposure estimate
for this population subgroup was less than 1% of the aPAD. The
petitioned crops in addition to the registered crop uses accounted for
less than 6% of the aPAD.
The addition of these new uses results in a DWLOC of approximately
1,400 ppb. Surface water concentration estimates increase from 1.5 ppb
to 1.6 ppb with the added crops. The aggregate exposure will not exceed
100% of the aPAD.
ii. Chronic risk. The chronic dietary chronic Population Adjusted
Dose (cPAD) was determined to be 0.01 mg/kg/day for the general
population based on an oral NOAEL of 0.97 mg/kg/day in the 2-year rat
chronic/carcinogenicity study. The Agency determined that exposure from
currently registered crops utilize 8% of the cPAD. The additional new
uses will result in a utilization of 10% of the cPAD. Using the
exposure assumptions previously described, EPA has concluded that
exposure to fenpyroximate from food, including the additional new uses,
will utilize 10% of the cPAD for the U.S. population, 21% of the cPAD
for all infants (<1 year old), and 33% of the cPAD for children (1-2
years old).
In addition, there is potential for chronic dietary exposure to
fenpyroximate in drinking water. The DWLOC for the general population,
infants (<1 year old) and children (1-6 years old) were 320 ppb, 82
ppb, and 71 ppb, respectively. Average yearly drinking water
concentration in surface water was estimated at 0.13 ppb, and 0.006 ppb
in ground water for both registered and petitioned uses. After
calculating the DWLOCs and comparing them to the EECs for surface and
ground water, the aggregate exposure will not exceed 100% of the cPAD.
2. Infants and children. The Agency confirmed the endpoint
selection for fenpyroximate and evaluated the potential for increased
susceptibility of infants and children from exposure to fenpyroximate
(July 2003). Based on toxicological considerations, the special FQPA
safety factor was set at 1X when assessing acute and chronic dietary
exposures.
3. Aggregate cancer risk for U.S. population. Fenpyroximate is
classified as not likely to be carcinogenic to humans; therefore, an
aggregate cancer risk assessment was not performed.
4. Determination of safety. Based on these risk assessments, EPA
