2002
(

(

EPA
issued
a
notice
pursuant
to
section
408
of
FFDCA,
21
U.
S.
C.

the
registrant.
There
were
no
comments
received
in
response
to
the
notice
of
filing.
The
petition
requested
that
40
CFR
180.510
be
amended
by
establishing
a
tolerance
for
residues
of
the
insecticide,
pyriproxyfen,
2­[
1­
methyl­
2­(
4­
phenoxyphenoxy)
ethoxypyridine,
in
or
on
Brassica
leafy
vegetables
(
Crop
Group
5);
vegetable,
cucurbit
(
Crop
Group
9);
olive
and
olive,
oil
at
2.5,
0.1,
1.0,
and
3.0
parts
per
million
(
ppm)
respectively.
Based
on
the
residue
data
submitted,
EPA
has
determined
that
the
following
changes
to
the
requested
tolerances
listed
in
this
document
are
necessary.
A
lower
tolerance
of
2.0
ppm
is
required
for
olive,
oil.
Brassica
vegetables
are
devided
into
two
subgroups.
A
tolerance
of
0.70
is
required
for
Brassica,
head
and
stem,
subgroup
5A.
A
tolerance
of
2.0
ppm
is
required
for
Brassica,
leafy
greens,
subgroup
5B.
Section
408(
b)(
2)(
A)(
i)
of
the
FFDCA
allows
EPA
to
establish
a
tolerance
(
the
legal
limit
for
a
pesticide
chemical
residue
in
or
on
a
food)
only
if
EPA
determines
that
the
tolerance
is
``
safe.''
Section
408(
b)(
2)(
A)(
ii)
of
the
FFDCA
defines
``
safe''
to
mean
that
``
there
is
a
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
the
pesticide
chemical
residue,
including
all
anticipated
dietary
exposures
and
all
other
exposures
for
which
there
is
reliable
information.''
This
includes
exposure
through
drinking
water
and
in
residential
settings,
but
does
not
include
occupational
exposure.
Section
408(
b)(
2)(
C)
of
the
FFDCA
requires
EPA
to
give
special
consideration
to
exposure
of
infants
and
children
to
the
pesticide
chemical
residue
in
establishing
a
tolerance
and
to
``
ensure
that
there
is
a
reasonable
certainty
that
no
harm
will
result
to
infants
and
children
from
aggregate
exposure
to
the
pesticide
chemical
residue....''
EPA
performs
a
number
of
analyses
to
determine
the
risks
from
aggregate
exposure
to
pesticide
residues.
For
further
discussion
of
the
regulatory
requirements
of
section
408
of
the
FFDCA

of
the
risk

process,

III.
Aggregate
Risk
Assessment
and
Determination
of
Safety
Consistent
with
section
408(
b)(
2)(
D)
of
the
FFDCA,
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,
consistent
with
section
408(
b)(
2)
of
the
FFDCA,
for
a
tolerance
for
residues
of
pyriproxyfen
on
Brassica,
head
and
stem,
subgroup
5A;
Brassica,
leafy
greens,
subgroup
5B;
Vegetable,
cucurbit
(
Group
9);
olive
and
olive,
oil
at
0.70,
2.0,
0.10,
1.0,
and
2.0
ppm,
respectively.
EPA's
assessment
of
exposures
and
risks
associated
with
establishing
the
tolerance
follows.

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.
The
nature
of
the
toxic
effects
caused
by
pyriproxyfen
are
discussed
in
Table
1
of
this
unit
as
well
as
the
no­
observed­
adverse­
effect­
level
(
NOAEL)
and
the
lowest­
observedadverse
effect­
level
(
LOAEL)
from
the
toxicity
studies
reviewed.

Toxicological
Endpoints
The
dose
at
which
no
adverse
effects
are
observed
(
the
NOAEL)
from
the
toxicology
study
identified
as
appropriate
for
use
in
risk
assessment
is
used
to
estimate
the
toxicological
level
of
concern
(
LOC).
However,
the
lowest
dose
at
which
adverse
effects
of
concern
are
identified
(
the
LOAEL)
is
sometimes
used
for
risk
assessment
if
no
NOAEL
was
achieved
in
the
toxicology
study
selected.
An
uncertainty
factor
(
UF)
is
applied
to
reflect
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.
An
UF
of
100
is
routinely
used,
10X
to
account
for
interspecies
differences
and
10X
for
intra
species
differences.
For
dietary
risk
assessment
(
other
than
cancer)
the
Agency
uses
the
UF
to
calculate
an
acute
or
chronic
reference
dose
(
acute
RfD
or
chronic
RfD)
where
the
RfD
is
equal
to
the
NOAEL
divided
by
the
appropriate
UF
(
RfD
=
NOAEL/
UF).
Where
an
additional
safety
factors
(
SF)
is
retained
due
to
concerns
unique
to
the
FQPA,
this
additional
factor
is
applied
to
the
RfD
by
dividing
the
RfD
by
such
additional
factor.
The
acute
or
chronic
Population
Adjusted
Dose
(
aPAD
or
cPAD)
is
a
modification
of
the
RfD
to
accommodate
this
type
of
FQPA
SF.
For
non­
dietary
risk
assessments
(
other
than
cancer)
the
UF
is
used
to
determine
the
LOC.
For
example,
when
100
is
the
appropriate
UF
(
10X
to
account
for
interspecies
differences
and
10X
for
intraspecies
differences)
the
LOC
is
100.
To
estimate
risk,
a
ratio
of
the
NOAEL
to
exposures
(
margin
of
exposure
(
MOE)
=
NOAEL/
exposure)
is
calculated
and
compared
to
the
LOC.

the
toxicological
endpoints
for
pyriproxyfen
used

assessment

C.
Exposure
Assessment
1.
Dietary
exposure
from
food
and
feed
uses.
Tolerances
have
been
established
(
40
CFR
180.510)
for
the
residues
of
pyriproxyfen,
in
or
on
a
variety
of
raw
agricultural
commodities.
Risk
assessments
were
conducted
by
EPA
to
assess
dietary
exposures
from
pyriproxyfen
in
food
as
follows:
i.
Acute
exposure.
Acute
dietary
risk
assessments
are
performed
for
a
fooduse
pesticide
if
a
toxicological
study
has
indicated
the
possibility
of
an
effect
of
concern
occurring
as
a
result
of
a
1­
day
or
single
exposure.
An
aRfD
for
females
13
 
50
years
old
and
the
general
population,
including
infants
and
children,
was
not
selected
because
an
acute
oral
endpoint
attributed
to
a
single­
dose
exposure
could
not
be
identified
in
any
of
the
toxicology
data
base,
including
maternal
toxicity
in
the
developmental
toxicity
studies.
Thus,
the
risk
from
acute
exposure
is
considered
negligible.
ii.
Chronic
exposure.
In
conducting
this
chronic
dietary
risk
assessment
the
Dietary
Exposure
Evaluation
Model
software
with
the
Food
Commodity
Intake
Database
(
DEEM­
FCIDTM),
version
1.3
analysis
evaluated
the
individual
food
consumption
as
reported
by
respondents
in
the
United
States
Department
of
Agricluture
(
USDA)
1994
 
1996
and
1998
Nationwide
Continuing
Surveys
of
Food
Intake
by
Individuals
(
CSFII)
and
accumulated
exposure
to
the
chemical
for
each
commodity.
The
following
assumptions
were
made
for
the
chronic
exposure
assessments:
a.
A
tier
1
(
assumptions:
Tolerance
level
residues
and
100
percent
crop
treated
(
PCT)
was
conducted.
b.
The
established
tolerances
of
40
CFR
180.510
and
the
new
tolerances
established
in
this
document
were
included
in
the
analysis.
c.
Anticipated
residues
and
PCT
were
not
used
in
this
analysis.
d.
The
processing
factors
applied
were
the
DEEM
default
values.
For
chronic
dietary
risk,
EPA's
level
of
concern
is
>
100%
cPAD.
Dietary
exposure
estimates
for
representative
population
subgroups
are
presented
in
Table
3
of
this
unit.
The
results
of
the
chronic
analysis
indicate
that
the
estimated
chronic
dietary
risk
associated
with
the
existing
and
EPArecommended
uses
of
pyriproxyfen
is
below
EPA's
level
of
concern.

Cancer.
In
accordance
with
the
Agency's
1986
Guidelines
for
Carcinogenic
Risk
Assessment,
the
RfD/
Peer
Review
Committee
classified
pyriproxyfen
as
a
``
Group
E''
chemicalnegative
for
carcinogenicity
to
humans.
This
classification
is
based
on
the
lack
of
evidence
of
carcinogenicity
in
mice
and
rats.
iv.
Anticipated
residue
and
PCT
information.
Anticipated
residues
and
PCT
information
was
not
used
in
the
Agency's
assessment.
2.
Dietary
exposure
from
drinking
water.
The
Agency
lacks
sufficient
monitoring
exposure
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
physical
characteristics
of
pyriproxyfen.
The
Agency
uses
the
Generic
Estimated
Environmental
Concentration
(
GENEEC)
or
the
Pesticide
Root
Zone/
Exposure
Analysis
Modeling
System
(
PRZM/
EXAMS)
to
estimate
pesticide
concentrations
in
surface
water
and
SCIGROW
which
predicts
pesticide
concentrations
in
groundwater.
In
general,
EPA
will
use
GENEEC
(
a
tier
1
model)
before
using
PRZM/
EXAMS
(
a
tier
2
model)
for
a
screening­
level
assessment
for
surface
water.
The
GENEEC
model
is
a
subset
of
the
PRZM/
EXAMS
model
that
uses
a
specific
highend
runoff
scenario
for
pesticides.
GENEEC
incorporates
a
farm
pond
scenario,
while
PRZM/
EXAMS
incorporate
an
index
reservoir
environment
in
place
of
the
previous
pond
scenario.
The
PRZM/
EXAMS
model
includes
a
percent
crop
area
factor
as
an
adjustment
to
account
for
the
maximum
percent
crop
coverage
within
a
watershed
or
drainage
basin.
None
of
these
models
include
consideration
of
the
impact
processing
(
mixing,
dilution,
or
treatment)
of
raw
water
for
distribution
as
drinking
water
would
likely
have
on
the
removal
of
pesticides
from
the
source
water.
The
primary
use
of
these
models
by
the
Agency
at
this
stage
is
to
provide
a
coarse
screen
for
sorting
out
pesticides
for
which
it
is
highly
unlikely
that
drinking
water
concentrations
would
ever
exceed
human
health
levels
of
concern.
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
%
RfD
or
%
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.
Since
DWLOCs
address
total
aggregate
exposure
to
pyriproxyfen
they
are
further
discussed
in
the
aggregate
risk
in
Unit
III.
E.
Pyriproxyfen
is
relatively
long­
lived
in
soil
and
water,
with
variable
halflives
of
approximately
2
weeks
to
2
months.
Pyriproxyfen
is
immobile,
as
indicated
by
the
relative
mobility
scheme
in
Dragun
(
1998)
for
five
soils
and
one
sediment.
The
registrant
determined
the
half­
lives,
6.8
and
9
days,
respectively,
for
the
phenyl­
label
and
pyridyl­
label
portions
of
pyriproxyfen.
Since
there
is
only
one
value,
the
longest
half­
life
(
9
days)
was
multiplied
by
3
using
EFED
input
guidance.
Thus,
the
aerobic
soil
half­
life
in
the
modeling
assessment
was
27
days.
EPA
determined
that
the
residue
of
concern
in
water
is
pyriproxyfen
per
se.
Drinking
water
estimates
include
surface
water
EDWCs
based
on
the
linked
PRZM/
EXAMS
models
and
the
SCI­
GROW
groundwater
regression
model,
which
was
developed
from
studies
with
different
hydrology
and
study
conditions.
Both
models
assumed
a
maximum
seasonal
application
rate
of
0.11
lb
active
ingredient
(
ai)/
acre
(
A),
3
times
per
year
(
citrus
and
stone
fruit).
Based
on
the
PRZM/
EXAMS
model
the
EECs
of
pyriproxyfen
for
surface
water
was
estimated
to
be
2.15
parts
per
billion
(
ppb)
for
the
peak
concentration,
and
0.40
ppb
for
the
long
term
average.
Based
on
the
SCI­
GROW
model
the
EECs
of
pyriproxyfen
for
groundwater
was
estimated
to
be
0.006
ppb
for
both
the
acute
and
chronic
exposure.
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
currently
registered
for
use
on
the
following
residential
nondietary
sites:
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).
There
is
a
potential
for
short­
term
dermal
and
inhalation
exposures
to
pet
owners
and
homeowners
who
apply
products
containing
pyriproxyfen
(
handlers);
however,
EPA
did
not
select
short­
term
dermal
or
inhalation
endpoints.
Therefore,
due
to
the
lack
of
toxicity
observed
in
animal
testing,
no
residential
pet
owner/
homeowner
handler
risk
of
concern
is
expected.
Toddlers
could
potentially
be
exposed
to
pyriproxyfen
residues
on
treated
carpets,
floors,
furniture,
and
pets.
There
is
potential
for
exposure
expected
for
the
following
scenarios:
i.
Hand­
to­
mouth.
Short­,
intermediate­,
and
long­
term
hand­
tomouth
exposures
by
toddlers
from
treated
carpets,
flooring
(
note
the
efficacy
of
carpet
powders
is
approximately
365
days).
ii.
Hand­
to­
mouth.
Short­
and
intermediate­
term
hand­
to­
mouth
exposures
by
toddlers
from
petting
treated
animals
(
shampoos,
sprays,
spoton
treatments,
and
collars).
Long­
term
hand­
to­
mouth
exposures
by
toddlers
from
petting
treated
animals
(
pet
collars;
note
efficacy
of
pet
collars
up
to
395
days).
iii.
Dermal.
Long­
term
dermal
exposures
from
treated
carpets,
flooring,
and
pets
(
note
that
treated
furniture
is
included
in
the
carpet/
flooring
assessment).
Due
to
the
lack
of
toxicity
observed
in
animal
testing,
the
Agency
did
not
select
any
short­
or
intermediate­
term
dermal
endpoints
and
no
dermal
risk
of
concern
for
these
durations
is
expected.
A
long­
term
dermal
assessment
is
included,
since
EPA
selected
a
long­
term
dermal
endpoint.
iv.
Ingestion
of
granules
or
bait
by
toddlers
(
acute,
episodic
event).
For
the
granular
ingestion
scenario,
it
should
be
noted
that
the
Agency
believes
that
if
a
toddler
were
to
be
exposed
to
a
pellet/
granular
formulation
(
i.
e.,
ant
bait),
the
event
is
most
likely
to
be
``
episodic,''
that
is,
a
one­
time
occurrence
and
not
likely
to
be
repeated.
It
is
not
likely
that
a
toddler
would
repeatedly
locate
and
ingest
very
small,
sand
colored
granules.
For
pyriproxyfen,
EPA
did
not
select
an
acute
dietary
endpoint,
since
an
appropriate
endpoint
could
not
be
attributed
to
a
single­
oral
dose;
therefore,
no
acute
dietary
risk
of
concern
is
expected.
Exposure
and
risk
estimates
from
post­
application
exposure
to
indoor
crack
and
crevice
treatments
are
not
presented
in
this
assessment,
as
indoor
broadcast
treatments
(
i.
e.,
carpet
powders
and
sprays)
are
anticipated
to
have
a
higher
exposure
potential.
Additionally,
the
Agency
acknowledges
that
pet
owners
could
retreat
the
home
environment
and/
or
the
pet
near
the
end
of
the
efficacy
period
identified
on
the
product
labels.
However,
there
are
no
chemical­
specific
residue
data
for
pyriproxyfen
to
determine
the
dissipation
rate
of
residues
or
whether
residues
may
be
additive
upon
retreatment.
Therefore,
a
tier
1
assessment
was
performed
based
on
day
0
residues
without
accounting
for
daily
residue
dissipation.
EPA
anticipates
that
this
assessment
is
protective
as
pyriproxyfen
residues
would
be
expected
to
dissipate
from
day
0
residue
values.
4.
Cumulative
exposure
to
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.''
EPA
does
not
have,
at
this
time,
available
data
to
determine
whether
pyriproxyfen
has
a
common
mechanism
of
toxicity
with
other
substances
or
how
to
include
this
pesticide
in
a
cumulative
risk
assessment.
Unlike
other
pesticides
for
which
EPA
has
followed
a
cumulative
risk
approach
based
on
a
common
mechanism
of
toxicity,
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
the
final
rule
for
Bifenthrin
Pesticide
Tolerances
(
62
FR
62961,
November
26,
1997).

D.
Safety
Factor
for
Infants
and
Children
1.
In
general.
Section
408
of
the
FFDCA
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
data
base
on
toxicity
and
exposure
unless
EPA
determines
that
a
different
margin
of
safety
will
be
safe
for
infants
and
children.
Margins
of
safety
are
incorporated
into
EPA
risk
assessments
either
directly
through
use
of
a
MOE
analysis
or
through
using
uncertainty
(
safety)
factors
in
calculating
a
dose
level
that
poses
no
appreciable
risk
to
humans.

Based
on
the
available
data,
there
is
no
quantitative
and
qualitative
evidence
of
increased
susceptibility
observed
following
in

to

or

in

3.
Conclusion.
There
is
a
complete
toxicity
data
base
for
pyriproxyfen
and
exposure
data
are
complete
or
are
estimated
based
on
data
that
reasonably
accounts
for
potential
exposures.
EPA
determined
that
the
10X
safety
factor
to
protect
infants
and
children
should
be
reduced
to
1X
because
there
was
no
evidence
of
prenatal
or
postnatal
extra
sensitivity
or
increased
susceptibility
in
developmental
studies
in
rats
and
rabbits,
and
in
reproduction
studies
in
rats.
Likewise,
there
was
no
quantitative
or
qualitative
evidence
of
increased
susceptibility
to
rat
or
rabbit
fetuses
identified
in
the
guideline
prenatal
developmental
toxicity
studies
for
rats
and
rabbits.
Additionally,
in
the
two
non­
guideline
studies
that
evaluated
perinatal
and
prenatal
development,
there
was
no
evidence
of
quantitative
or
qualitative
increased
susceptibility.
In
one
study,
when
pregnant
rats
were
treated
from
gestation
day
17
to
lactation
day
20,
the
resulting
toxicity
was
comparable
between
adults
(
clinical
signs,
decreased
body
weight
gain
and
food
consumption)
and
offspring
(
decreased
body
weight
and
dilation
of
the
renal
pelvis)
at
the
same
dose.
In
the
other
study,
when
rats
were
exposed
to
pyriproxyfen
prior
to
and
in
the
early
stages
of
pregnancy,
no
developmental
toxicity
was
seen
at
the
limit
dose.
Lastly,
in
the
reproduction
toxicity
study,
offspring
toxicity
(
decreased
body
weight
on
pups
during
lactation
days
14
to
21)
occurred
only
in
the
presence
of
decreases
in
body
weight
in
parental
animals
at
the
same
dose
level
(
i.
e.,
comparable
toxicity
in
adults
and
offspring).
E.
Aggregate
Risks
and
Determination
of
Safety
To
estimate
total
aggregate
exposure
to
a
pesticide
from
food,
drinking
water,
and
residential
uses,
the
Agency
calculates
DWLOCs
which
are
used
as
a
point
of
comparison
against
the
model
estimates
of
a
pesticide's
estimated
environmental
concentration
in
water
(
EECs).
DWLOC
values
are
not
regulatory
standards
for
drinking
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
residential
uses.
In
calculating
a
DWLOC,
the
Agency
determines
how
much
of
the
acceptable
exposure
(
i.
e.,
the
PAD)
is
available
for
exposure
through
drinking
water
(
e.
g.,
allowable
chronic
water
exposure
(
mg/
kg/
day)
=
cPAD
­
(
average
food
+
residential
exposure)).
This
allowable
exposure
through
drinking
water
is
used
to
calculate
a
DWLOC.
A
DWLOC
will
vary
depending
on
the
toxic
endpoint,
drinking
water
consumption,
and
body
weights.
Default
body
weights
and
consumption
values
as
used
by
the
EPA
Office
of
Water
are
used
to
calculate
DWLOCs:
2
L/
70
kg
(
adult
male),
2
L/
60
kg
(
adult
female),
and
1
L/
10
kg
(
child).
Default
body
weights
and
drinking
water
consumption
values
vary
on
an
individual
basis.
This
variation
will
be
taken
into
account
in
more
refined
screening­
level
and
quantitative
drinking
water
exposure
assessments.
Different
populations
will
have
different
DWLOCs.
Generally,
a
DWLOC
is
calculated
for
each
type
of
risk
assessment
used:
Acute,
short­
term,
intermediate­
term,
chronic,
and
cancer.
When
EECs
for
surface
water
and
groundwater
are
less
than
the
calculated
DWLOCs,
OPP
concludes
with
reasonable
certainty
that
exposures
to
the
pesticide
in
drinking
water
(
when
considered
along
with
other
sources
of
exposure
for
which
OPP
has
reliable
data)
would
not
result
in
unacceptable
levels
of
aggregate
human
health
risk
at
this
time.
Because
OPP
considers
the
aggregate
risk
resulting
from
multiple
exposure
pathways
associated
with
a
pesticide's
uses,
levels
of
comparison
in
drinking
water
may
vary
as
those
uses
change.
If
new
uses
are
added
in
the
future,
OPP
will
reassess
the
potential
impacts
of
residues
of
the
pesticide
in
drinking
water
as
a
part
of
the
aggregate
risk
assessment
process.
1.
Acute
risk.
An
acute
dietary
RfD
for
females
13
 
49
and
the
general
U.
S.
population,
including
infants
and
children,
was
not
selected
because
an
acute
oral
endpoint
attributable
to
a
single­
dose
exposure
could
not
be
identified
in
the
toxicology
data
base,
including
maternal
toxicity
in
the
developmental
toxicity
studies.
No
acute
dietary
risk
is
expected.
2.
Chronic
risk.
Using
the
exposure
assumptions
described
in
this
unit
for
chronic
exposure,
EPA
has
concluded
that
exposure
to
pyriproxyfen
from
food
will
utilize
1.1%
of
the
cPAD
for
the
U.
S.
population,
2.0%
of
the
cPAD
for
all
infant,
s
and
3.9%
of
the
cPAD
for
children
1
 
2
years
old.
Pyriproxyfen
is
the
active
ingredient
in
many
registered
residential
products
for
flea
and
tick
control
on
pets
and
in
the
home
for
ant
and
roach
control
for
indoor
and
outdoor
applications.
Based
on
the
use
pattern,
the
residential
assessment
was
performed
for
toddlers
since
they
are
anticipated
to
have
the
higher
chronic
residential
exposure
to
residues
of
pyriproxyfen.
The
total
chronic
food
and
residential
aggregate
MOEs
range
from
850
to
13,000.
As
these
MOEs
are
greater
than
100,
the
chronic
aggregate
risk
does
not
exceed
EPA's
level
of
concern.
In
addition,
there
is
potential
for
chronic
dietary
exposure
to
pyriproxyfen
in
drinking
water.
After
calculating
DWLOCs
and
comparing
them
to
the
EECs
for
surface
and
ground
water,
EPA
does
not
expect
the
aggregate
exposure
to
exceed
100%
of
the
cPAD,

shown
in

Short­
term
risk.
Short­
term
aggregate
exposure
takes
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
residential
exposure
and
the
Agency
has
determined
that
it
is
appropriate
to
aggregate
chronic
food
and
water
and
short­
term
exposures
for
pyriproxyfen.
Using
the
exposure
assumptions
described
in
this
unit
for
short­
term
exposures,
EPA
has
concluded
that
food
and
residential
exposures
aggregated
result
in
aggregate
MOEs
of
26,000
for
the
U.
S.
population,
1,800
for
all
infants(<

and
1,600

These
aggregate
MOEs
do
not

the
Agency's
level
of

for
aggregate
exposure
to
food

residential
uses.
In

Intermediate­

exposure
takes
into

residential
exposure
plus
chronic
exposure
to
food
and
water
(
considered
to
be
a

level).
Pyriproxyfen
is
currently
registered
for
use(
s)
that
could
result
in
intermediate­
term
residential
exposure
and
the
Agency
has
determined
that
it
is
appropriate
to
aggregate
chronic
food
and
water
and
intermediate­
term
exposures
for
pyriproxyfen.
Using
the
exposure
assumptions
described
in
this
unit
for
intermediateterm
exposures,
EPA
has
concluded
that
food
and
residential
exposures
aggregated
result
in
aggregate
MOEs
of
9,200
for
the
U.
S.
population,
650
for
all
infants
(<

and
580
for

These
aggregate
MOEs
do
not
exceed
the
Agency's
level
of
concern
for
aggregate

Objections
and
Hearing
Requests
Under
section
408(
g)
of
the
FFDCA,
as
amended
by
the
FQPA,
any
person
may
file
an
objection
to
any
aspect
of
this
regulation
and
may
also
request
a
hearing
on
those
objections.
The
EPA
procedural
regulations
which
govern
the
submission
of
objections
and
requests
for
hearings
appear
in
40
CFR
part
178.
Although
the
procedures
in
those
regulations
require
some
modification
to
reflect
the
amendments
made
to
the
FFDCA
by
the
FQPA,
EPA
will
continue
to
use
those
procedures,
with
appropriate
adjustments,
until
the
necessary
modifications
can
be
made.
The
new
section
408(
g)
of
the
FFDCA
provides
essentially
the
same
process
for
persons
to
``
object''
to
a
regulation
for
an
exemption
from
the
requirement
of
a
tolerance
issued
by
EPA
under
new
section
408(
d)
of
FFDCA,
as
was
provided
in
the
old
sections
408
and
409
of
the
FFDCA.
However,
the
period
for
filing
objections
is
now
60
days,
rather
than
30
days.

VII.
Statutory
and
Executive
Order
Reviews
This
final
rule
establishes
a
tolerance
under
section
408(
d)
of
the
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
due
to
its
lack
of
significance,
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).
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.,
or
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).
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);
or
OMB
review
or
any
Agency
action
under
Executive
Order
13045,
entitled
Protection
of
Children
from
Environmental
Health
Risks
and
Safety
Risks
(
62
FR
19885,
April
23,
1997).
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).
Since
tolerances
and
exemptions
that
are
established
on
the
basis
of
a
petition
under
section
408(
d)
of
the
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.
In
addition,
the
Agency
has
determined
that
this
action
will
not
have
a
substantial
direct
effect
on
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government,
as
specified
in
Executive
Order
13132,
entitled
Federalism(
64
FR
43255,
August
10,
1999).
Executive
Order
13132
requires
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
State
and
local
officials
in
the
development
of
regulatory
policies
that
have
federalism
implications.''
``
Policies
that
have
federalism
implications''
is
defined
in
the
Executive
order
to
include
regulations
that
have
``
substantial
direct
effects
on
the
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government.''
This
final
rule
directly
regulates
growers,
food
processors,
food
handlers,
and
food
retailers,
not
States.
This
action
does
not
alter
the
relationships
or
distribution
of
power
and
responsibilities
established
by
Congress
in
the
preemption
provisions
of
section
408(
n)(
4)
of
the
FFDCA.
For
these
same
reasons,
the
Agency
has
determined
that
this
rule
does
not
have
any
``
tribal
implications''
as
described
in
Executive
Order
13175,
entitled
Consultation
and
Coordination
with
Indian
Tribal
Governments
(
65
FR
67249,
November
6,
2000).
Executive
Order
13175,
requires
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
tribal
officials
in
the
development
of
regulatory
policies
that
have
tribal
implications.''
``
Policies
that
have
tribal
implications''
is
defined
in
the
Executive
order
to
include
regulations
that
have
``
substantial
direct
effects
on
one
or
more
Indian
tribes,
on
the
relationship
between
the
Federal
Government
and
the
Indian
tribes,
or
on
the
distribution
of
power
and
responsibilities
between
the
Federal
Government
and
Indian
tribes.''
This
rule
will
not
have
substantial
direct
effects
on
Tribal
governments,
on
the
relationship
between
the
Federal
Government
and
Indian
tribes,
or
on
the
distribution
of
power
and
responsibilities
between
the
Federal
Government
and
Indian
Tribes,
as
specified
in
Executive
Order
13175.
Thus,
Executive
Order
13175
does
not
apply
to
this
rule.

VIII.
Congressional
Review
Act
The
Congressional
Review
Act,
5
U.
S.
C.
801
et
seq.,
as
added
by
the
Small
Business
Regulatory
Enforcement
Fairness
Act
of
1996,
generally
provides
that
before
a
rule
may
take
effect,
the
agency
promulgating
the
rule
must
submit
a
rule
report,
which
includes
a
copy
of
the
rule,
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).
