Electronically.
If
you
submit
an

prescribed
in
this

EPA
recommends
that
you
include
your
name,
mailing
address,
and
an
email
address
or
other
contact
information
in
the
body
of
your

outside
of
any
disk
or
CD
ROM
you
submit,
and
in
any
cover
letter
accompanying
the
disk
or
CD
ROM.
This
ensures
that
you
can
be
identified
as
the
submitter
of
the
comment
and
allows
EPA
to
contact
you
in
case
EPA
cannot
read
your
comment
due
to
technical
difficulties
or
needs
further
information
on
the
substance
of
your
comment.
EPA's
policy
is
that
EPA
will
not
edit
your
comment,
and
any
identifying
or
contact
information
provided
in
the
body
of
a

of
the
comment
that

A.
Residue
Chemistry
1.
Plant
metabolism.
The
qualitative
nature
of
methoxyfenozide
residues
in
plants
and
animals
is
adequately
understood
and
was
previously
published
in
the
Federal
Register
of
July
5,
2000
(

FR
41355)
(
FRL

2.
Analytical
method.
Adequate
enforcement
methods
are
available
for
determination
of
methoxyfenozide
residues
in
plant
commodities.
The
available
Analytical
Enforcement
Methodology
was
previously
reviewed
in
the
Federal
Register
of
(
September
20,
2002

FR

3.
Magnitude
of
residues.
Complete
residue
data
for
methoxyfenozide
on
okra;
turnip
greens;
cucurbit
vegetables;
pea,
blackeyed;
and
pea,
southern
have
been
submitted.
The
requested
tolerances
are
adequately
supported.
B.
Toxicological
profile
The
toxicological
profile
and
endpoints
for
methoxyfenozide
which
supports
this
petition
to
establish
tolerances
were
previously
published
in
the
Federal
Register
of
September
20,
2002
(

(

C.
Aggregate
Exposure
1.
Dietary
exposure.
Assessments
were
conducted
to
evaluate
potential
risks
due
to
chronic
and
acute
dietary
exposure
of
the
U.
S.
population
subgroups
to
residues
of
methoxyfenozide.
These
analysis
cover
all
registered
crops,
as
well
as,
uses
pending
with
the
Agency,
active
and
proposed
section
18
uses,
and
proposed
IR­
4
minor
uses.
There
are
no
registered
residential
nonfood
uses
of
methoxyfenozide.
i.
Food
 
a.
Acute
exposure.
No
appropriate
toxicological
endpoint
attributable
to
a
single
exposure
was
identified
in
the
available
toxicology
studies
on
methoxyfenozide
including
the
acute
neurotoxicity
study
in
rats,
the
developmental
toxicity
study
in
rats
and
the
developmental
toxicity
study
in
rabbits.
Since
no
acute
toxicological
endpoints
were
established,
Dow
AgroSciences
considers
acute
aggregate
risk
to
be
negligible.
b.
Chronic
exposure.
Dow
AgroSciences
assumed
100%
of
crops
would
be
treated
and
contain
methoxyfenozide
residues
at
the
tolerance
level.
Dow
AgroSciences
used
the
Dietary
Exposure
Evaluation
Model
(
DEEMTM,
Novigen
Sciences,
Washington,
DC)
software
for
conducting
a
chronic
dietary
(
food)
risk
analysis.
DEEMTM
is
a
dietary
exposure
analysis
system
that
is
used
to
estimate
exposure
to
a
pesticide
chemical
in
foods
comprising
the
diets
of
the
U.
S.
population,
including
population
subgroups.
DEEMTM
contains
food
consumption
data
as
reported
by
respondents
in
the
Department
of
Agriculture
(
USDA)
continuing
surveys
of
food
intake
by
individuals
conducted
in
1994
 
1996.
ii.
Drinking
water
 
Acute
exposure.
Because
no
acute
dietary
endpoint
was
determined,
Dow
AgroSciences
concludes
that
there
is
a
reasonable
certainty
of
no
harm
from
acute
exposure
from
drinking
water.

The

2.
Non­
dietary
exposure.
Methoxyfenozide
is
not
currently
registered
for
use
on
any
residential
non­
food
sites.
Therefore,
there
is
no
non­
dietary
acute,
chronic,
short­
term
or
intermediate­
term
exposure.

D.
Cumulative
Effects
Section
(
408)(
b)(
2)(
D)(
v)
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
methoxyfenozide
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,
methoxyfenozide
does
not
appear
to
produce
a
toxic
metabolite
produced
by
other
substances.
For
the
purposes
of
this
tolerance
action,
therefore,
it
is
assumed
that
methoxyfenozide
does
not
have
a
common
mechanism
of
toxicity
with
other
substances.

E.
Safety
Determination
1.
U.
S.
population.
Using
the
DEEMTM
exposure
assumptions
described
in
this
unit,
Dow
AgroSciences
has
concluded
that
aggregate
exposure
to
methoxyfenozide
from
the
proposed
new
tolerances
will
utilize
18.9%
of
the
chronic
pollution
adjusted
dose
(
cPAD)
for
the
U.
S.
population.
The
major
identifiable
subgroup
with
the
highest
aggregate
exposure
is
children
1
 
6
years
old
at
37.6%
of
the
cPAD
and
is
discussed
below.
EPA
generally
has
no
concern
for
exposures
below
100%
of
the
cPAD
because
the
cPAD
represents
the
level
at
or
below
which
daily
aggregate
dietary
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
Despite
the
potential
for
exposure
to
methoxyfenozide
in
drinking
water,
the
aggregate
exposure
is
not
expected
to
exceed
100%
of
the
cPAD.
Dow
AgroSciences
concludes
that
there
is
a
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
methoxyfenozide
residues.
2.
Infants
and
children.
FFDCA
section
408
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
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
margin
of
exposure
(
MOE)
analysis
or
through
using
uncertainty
(
safety)
factors
in
calculating
a
dose
level
that
poses
no
appreciable
risk
to
humans.
EPA
believes
that
reliable
data
support
using
the
standard
uncertainty
factor
(
UF)
usually
100
for
combine
inter­
species
and
intra­
species
variability
and
not
the
additional
tenfold
MOE/
UF
when
EPA
has
a
complete
data
base
under
existing
guidelines
and
when
the
severity
of
the
effect
in
infants
or
children
or
the
potency
or
unusual
toxic
properties
of
a
compound
do
not
raise
concerns
regarding
the
adequacy
of
the
standard
MOE/
safety
factor.
The
toxicology
data
base
for
methoxyfenozide
included
acceptable
developmental
toxicity
studies
in
both
rats
and
rabbits
as
well
as
a
2­
generation
reproductive
toxicity
study
in
rats.
The
data
provided
no
indication
of
increased
sensitivity
of
rats
or
rabbits
to
in
utero
and/
or
postnatal
exposure
to
methoxyfenozide.
There
is
a
complete
toxicity
data
base
for
methoxyfenozide
and
exposure
data
are
complete
or
are
estimated
based
on
data
that
reasonably
accounts
for
potential
exposures.
Based
on
the
completeness
of
the
data
base
and
the
lack
of
prenatal
and
postnatal
toxicity,
EPA
determined
that
an
additional
safety
factor
was
not
needed
for
the
protection
of
infants
and
children.
Since
no
toxicological
endpoints
were
established,
acute
aggregate
risk
is
considered
to
be
negligible.
Using
the
exposure
assumptions
described
in
this
unit,
Dow
AgroSciences
has
concluded
that
aggregate
exposure
to
methoxyfenozide
from
the
proposed
new
tolerances
will
utilize
37.6%
of
the
cPAD
for
infants
and
children.
EPA
generally
has
no
concern
for
exposures
below
100%
of
the
cPAD
because
the
cPAD
represents
the
level
at
or
below
which
daily
aggregate
dietary
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
Drinking
water.
The
back­
calculated
drinking
water
levels
of
concern
(
DWLOCs)
for
assessing
chronic
aggregate
dietary
risk
range
from
624
ppb
for
the
most
highly
exposed
population
subgroup
children
(
1
to
6)
years
old
to
2,839
ppb
for
the
U.
S.
population
(
48
contiguous
States)
(
all
seasons).
Despite
the
potential
for
exposure
to
methoxyfenozide
in
drinking
water,
Dow
AgroSciences
does
not
expect
the
aggregate
exposure
to
exceed
100%
of
the
cPAD.
Short­
term
and
intermediate­
term
risks
are
judged
to
be
negligible
due
to
the
lack
of
significant
toxicological
effects
observed.
Based
on
these
risk
assessments,
Dow
AgroSciences
concludes
that
there
is
a
reasonable
certainty
that
no
harm
will
result
to
infants
and
children
from
aggregate
exposure
to
methoxyfenozide
residues.

F.
International
Tolerances
There
are
no
Codex
or
Canadian
maximum
residue
levels
(
MRL's)
established
for
residues
of
methoxyfenozide.
Mexican
MRL's
are
established
for
residues
of
methoxyfenozide
in
cottonseed
0.05
ppm
and
maize
0.01
ppm.
The
U.
S.
tolerances
on
these
commodities
are
2.0
ppm
and
0.05
ppm,
respectively.
Based
on
the
current
use
patterns,
the
U.
S.
tolerance
levels
cannot
be
reduced
to
harmonize
with
the
Mexican
MRL's,
so
incompatibility
will
exist.
