Pesticide
Tolerances
AGENCY:
Environmental
Protection
Agency
(
EPA).

ACTION:
Final
rule.

SUMMARY:
This
regulation
establishes
tolerances
for
combined
residues
of
bifenazate
and
diazinecarboxylic
acid,
2­(
4­
methoxy­[
1,1'­
biphenyl]­
3­

1­
methylethyl
ester
(
expressed
as
bifenazate)
in
or
on
almond,
hulls;
nut,
tree,
group
14;
okra;
peppermint,
tops;
pistachio;
spearmint,
tops;
vegetable,
cucurbit,
group
9;
and,
vegetable,
fruiting,
group
8;
and
increases
the
established
tolerances
for
combined
residues
of
bifenazate;
diazinecarboxylic
acid,
2­(
4­
methoxy­[
1,1'­
biphenyl]­
3­
yl),
1­
methylethyl
ester
(
expressed
as
bifenazate);
1,1'­
biphenyl,
4­
ol;
and
1,1'­
biphenyl,
4­
oxysulfonic
acid
(
expressed
as
1,1'­
biphenyl,
4­
ol)
in
meat
and
meat
byproducts
of
cattle,
goat,
hog,
horse,
and
sheep
and
milk.
EPA
is
also
deleting
the
bifenazate
time­
limited
tolerance
for
tomato,
which
is
established
in
connection
with
a
section
18
emergency
exemption.
Tomato
is
included
in
the
tolerance
established
by
this
action
for
vegetable,
fruiting
group
8.
The
Interregional
Research
Project
Number
4
(
IR­
4)
requested
these
tolerances
under
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA),
as
amended
by
the
Food
Quality
Protection
Act
of
1996
(
FQPA).

EPA
issued
a
notice
pursuant
to
section
408
of
FFDCA,
21
U.
S.
C.
346a,
as
amended
by
FQPA
(
Public

prepared
by
Crompton
Manufacturing
Company,
Inc.
(
formerly
Uniroyal
Chemical
Company),
Middlebury,
CT
06749,
the
registrant.
The

be
amended
by
establishing
tolerances
for
combined
residues
of
the
miticide,
bifenazate,
(

There
were
no
comments
received
on
these
petitions.
EPA
has
received
objections
to
tolerances
it
established
for
residues
of
bifenazate
on
a
variety
of
food
commodities
in
a
final
rule
published
in
the
Federal
Register
of
February
1,
2002
(
67
FR
4913)
(
FRL
 
6818
 
3).
The
objections
were
filed
by
the
Natural
Resources
Defense
Council
(
NRDC)
and
raised
several
issues
regarding
aggregate
exposure
estimates
and
the
additional
safety
factor
for
the
protection
of
infants
and
children.
NRDC's
objections
raise
complex
legal,
scientific,
policy,
and
factual
matters
and
EPA
has
initiated
a
public
comment
period
on
them
in
the
Federal
Register
of
June
19,
2002
(
67
FR
41628)
(
FRL
 
7167
 
7),
which
ended
on
October
16,
2002.
Although
that
proceeding
remains
ongoing,
prior
to
acting
on
this
current
tolerance
action,
EPA
reviewed
the
bifenazate­
specific
objections
raised
by
NRDC
and
has
addressed
them
at
relevant
points
throughout
this
preamble.
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

408
of
the
FFDCA

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
bifenazate
are
discussed
in
Table
1
of
this

adverse­
effect­
level
(
NOAEL)
and
the
lowest­
observedadverse

and
in

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

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
linear
default
risk
methodology
(
Q*)
is
the
primary
method
currently
used
by
the
Agency
to
quantify
carcinogenic
risk.
The
Q*
approach
assumes
that
any
amount
of
exposure
will
lead
to
some
degree
of
cancer
risk.
A
Q*
is
calculated
and
used
to
estimate
risk
which
represents
a
probability
of
occurrence
of
additional
cancer
cases
(
e.
g.,
risk
is
expressed
as
1
x
10­
6
or
one
in
a
million).
Under
certain
specific
circumstances,
MOE
calculations
will
be
used
for
the
carcinogenic
risk
assessment.
In
this
non­
linear
approach,
a
``
point
of
departure''
is
identified
below
which
carcinogenic
effects
are
not
expected.
The
point
of
departure
is
typically
a
NOAEL
based
on
an
endpoint
related
to
cancer
effects
though
it
may
be
a
different
value
derived
from
the
dose
response
curve.
To
estimate
risk,
a
ratio
of
the
point
of
departure
to
exposure
(
MOEcancer
=
point
of
departure/
exposures)
is
calculated.

the

ii.
Chronic
exposure.
In
conducting
this
chronic
dietary
risk
assessment
EPA
used
the
Dietary
Exposure
Evaluation
Model
software
with
the
Food
Commodity
Intake
Database
(
DEEMFCIDTM
which
incorporates
food
consumption
data
as
reported
by
respondents
in
the
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
was
made
for
the
chronic
exposure
assessment:
The
chronic
dietary
exposure
analysis
assumed
tolerance
level
residues
and
100%
crop
treated
for
all
registered
and
proposed
crops
excluding
tomato
where
average
field
trial
residues
were
used.
DEEM
(
ver
7.73)
default
processing
factors
were
assumed
for
all
commodities
excluding
apple
juice,
grape
juice,
wine/
sherry,
tomato
paste,
and
tomato
puree.
The
processing
factors
for
these
commodities
were
reduced
to
0.23,
0.17,
0.17,
5.0,
and
5.0,
respectively,
based
on
data
from
processing
studies.
In
its
objections
to
the
earlier
bifenazate
tolerance
action,
NRDC
claims
that
EPA
relied
upon
unsupported
and
apparently
arbitrary
processing
factors
to
reduce
estimates
of
dietary
exposure
to
bifenazate
on
apples
and
grapes.
NRDC
was
incorrect
to
assert
that
the
processing
factors
for
apples
and
grapes
were
unsupported
and
arbitrary.
The
DEEM
processing
factors
for
apple
juice
and
grape
juice
used
for
this
action
and
the
earlier
bifenazate
tolerance
action
are
based
on
data
from
processing
studies.
In
this
action,
the
Agency
used
DEEM
(
ver
7.73)
default
processing
factors
when
processing
studies
were
not
available.
These
default
factors
are
worst
case
assumptions
regarding
pesticide
partitioning
into
component
commodity
fractions.
DEEM
(
ver
7.73)
default
processing
factors
assume
that
100
percent
of
the
pesticide
that
was
originally
present
in
the
commodity
is
present
in
the
processed
fractions.
This
is
a
worst
case
theoretical
concentration
factor
since
it
assumes
that
processing
does
not
result
in
any
reduction
in
pesticide
content.
iii.
Cancer.
EPA
has
classified
bifenazate
as
a
not
likely
human
carcinogen.
Therefore,
a
quantitative
cancer
dietary
exposure
and
risk
assessment
was
not
performed.
2.
Dietary
exposure
from
drinking
water.
The
Agency
lacks
sufficient
monitoring
exposure
data
to
complete
a
comprehensive
dietary
exposure
analysis
and
risk
assessment
for
bifenazate
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
bifenazate.
The
Agency
uses
the
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.
The
SCI­
GROW
model
is
used
to
predict
pesticide
concentrations
in
shallow
groundwater.
For
a
screeninglevel
assessment
for
surface
water
EPA
will
use
FIRST
(
a
tier
1
model)
before
using
PRZM/
EXAMS
(
a
tier
2
model).
The
FIRST
model
is
a
subset
of
the
PRZM/
EXAMS
model
that
uses
a
specific
high­
end
runoff
scenario
for
pesticides.
FIRST
and
PRZM/
EXAMS
incorporate
an
index
reservoir
environment,
and
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
screen
for
sorting
out
pesticides
for
which
it
is
unlikely
that
drinking
water
concentrations
would
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
bifenazate
they
are
further
discussed
in
the
aggregate
risks
in
Unit

E.
Parent
bifenazate
degrades
rapidly
in
aerobic
soil
conditions
with
a
half­
life
of
approximately
30
minutes.
The
first
degradate
formed
(
D3598
(
diazinecarboxylic
acid,
2­(
4­
methoxy­
1,1'­
biphenyl­
3­
yl)
(
half­
life
of
7
hours))
was
reported
in
a
concentration
of
95%
of
the
applied
radioactivity.
D3598
degrades
to
D1989
(
4­
methylethylester)
(
reported
at
a
maximum
of
26%
of
the
applied
radioactivity),
which
is
moderately
persistent
with
an
EPAcalculated
half­
life
of
approximately
96
days.
Photodegradation
and
other
routes
of
dissipation
of
parent
bifenazate
do
not
appear
to
be
significant.
The
Agency
concluded
that
the
residue
of
concern
in
drinking
water
is
D1989.
Parent
and
D3598
were
not
included
as
a
residue
of
concern
in
drinking
water
due
to
the
short
halflives
of
these
compounds
and
the
lack
of
an
acute
dietary
endpoint
(
toxicity
of
D3598
is
assumed
to
be
equivalent
to
bifenazate).
Since
ground
or
surface
water
monitoring
data
to
calculate
a
quantitative
aggregate
exposure
are
not
available,
EPA
provided
Tier
I
ground
(
SCI­
GROW)
and
surface
water
(
FIRST)
EECs
for
D1989.
Both
models
were
conducted
using
the
strawberry
application
scenario
(
one
application
at
0.75
lbs
ai/
acre;
highest
registered/
proposed
application
rate).
The
resulting
ground
and
surface
water
chronic
EECs
are
<
0.001
ppb
and
6.4
ppb,
respectively.
In
its
objections
to
a
separate
bifenazate
tolerance
action,
NRDC
asserts
that
EPA
failed
to
complete
an
assessment
of
drinking
water
exposure
to
bifenazate
degradates.
As
stated
in
the
Federal
Register
final
rule
of
February
1,
2002,
and
restated
in
this
document,
EPA
considered
the
environmental
persistence
of
bifenazate
and
its
two
major
metabolites
D3598
and
D1989.
Aqueous
photolysis
and
soil
metabolism
studies
demonstrated
that
the
parent
bifenazate
and
the
D3598
degradate
quickly
metabolize
under
aerobic
soil
conditions.
Noting
the
lack
of
persistence
of
these
two
compounds
and
the
absence
of
any
acute
dietary
endpoint,
EPA
focused
its
drinking
water
exposure
assessment
for
bifenazate
on
the
degradate
(
D1989)
that
had
a
possibility
of
being
present
in
drinking
water.
Accordingly,
NRDC
is
incorrect
to
assert
that
potential
exposure
to
bifenazate
degredates
in
drinking
water
was
not
assessed
by
EPA.
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).
In
its
objections
to
a
separate
bifenazate
tolerance
action,
NRDC
asserts
that
EPA
failed
to
assess
and
incorporate
residential
uses
as
a
source
of
aggregate
exposure.
In
the
current
risk
assessment,
EPA
calculated
short­
term
residential
risks
to
homeowner
applicators.

However,
the
Agency
concluded
that
no
significant
post­
application
exposure
is
aniticipated
from
landscape
ornamentals;
therefore,
no
residential
post­
application
assessment
was
conducted.
Bifenazate
is
currently
registered
for
use
on
the
following
residential
nondietary
sites:
Commercial
application
to
ornamental
plants
(
including
bedding
plants,
flowering
plants,
foliage
plants,
bulb
crops,
perennials,
trees
and
shrubs;
not
turf)
and
all
fruit
trees
which
will
not
bear
fruit
for
a
minimum
of
12
months.
The
registrant
has
proposed
an
amendment
to
the
Floramite
(
EPA
Reg.
No.

508)
label
to
permit
application
to
home
ornamental
plants
and
fruit
trees
that
will
not
bear
fruit
within
12
months
by
residents/
homeowners.
The
risk
assessment
was
conducted
using
the
following
residential
exposure
assumptions:
EPA
anticipates
only
short­
term
dermal
and
short­
term
inhalation
exposure
for
the
residential
handler
(
applicator).
The
proposed
formulation
is
appropriate
for
application
via
pump
up
sprayers,
garden
hose­
end
sprayers
or
similar
homeowner
pesticide
devices.
A
larger
area
per
day
may
be
treated
with
a
hoseend
sprayer
than
with
a
pump
up
compressed
air
sprayer,
which
in
turn
results
in
possibly
greater
contact
with
the
active
ingredient
per
day.
Therefore,
exposure
from
a
hose­
end
sprayer
is
assessed
rather
than
that
of
a
compressed
air
sprayer.
For
the
treatment
of
shrubs
and
ornamentals,
EPA
assume
100
gallons
of
finish
spray
are
applied
per
day.
The
unit
exposure

for
a

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.
EPA
does
not
have,
at
this
time,
available
data
to
determine
whether
bifenazate
has
a
common
mechanism
of
toxicity
with
other
substances.
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
bifenazate
and
any
other
substances
and
bifenazate
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
bifenazate
has
a
common
mechanism
of
toxicity
with
other
substances.

EPA's

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.
2.
Prenatal
and
postnatal
sensitivity.
There
is
no
indication
of
qualitative
or
quantitative
increased
susceptibility
of
rats
and
rabbits
during
in
utero
exposure
or
post­
natal
exposure
based
on
developmental
toxicity
and
reproductive
toxicity
studies
performed
with
bifenazate.
3.
Conclusion.
There
is
a
complete
toxicity
data
base
for
bifenazate
and
exposure
data
are
complete
or
are
estimated
based
on
data
that
reasonably
accounts
for
potential
exposures.
EPA
determined
that
the
10X
SF
to
protect
infants
and
children
should
be
reduced
to
1X
for
the
following
reasons:
Acceptable
developmental
toxicity
studies
in
the
rat
and
the
rabbit
are
available,
as
is
an
acceptable
2­
generation
reproduction
study
in
the
rat
and
there
is
no
indication
of
qualitative
or
quantitative
increased
susceptibility
of
rats
and
rabbits
to
in
utero
or
postnatal
exposure.
A
developmental
neurotoxicity
study
is
not
required
for
bifenazate.
The
dietary
(
food
and
water)
and
non­
dietary
(
residential)
exposure
assessments
are
not
expected
to
underestimate
the
potential
exposures
for
infants
and
children
from
the
use
of
bifenazate.

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
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
USEPA
Office
of
Water
are
used
to
calculate
DWLOCs:
2

70
kg
(
adult
male),
2L/
60
kg
(
adult

and

Default
body
weights
and
drinking
water
consumption
values
vary
on
an
individual
basis.

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
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
one
day
or
single
exposure.
Bifenazate
is
not
expected
to
pose
an
acute
risk
to
humans.
2.
Chronic
risk.
Using
the
exposure
assumptions
described
in
this
unit
for
chronic
exposure,
EPA
has
concluded
that
exposure
to
bifenazate
from
food
will
utilize
24%
of
the
cPAD
for
the
U.
S.
population,
59%
of
the
cPAD
for
all
infants
<
1
year
old,
85%
of
the
cPAD
for
children
1
 
2
years
old
(
the
most
highly
exposed
population
subgroup),
and
17%
of
the
cPAD
for
females
13
 
49
years
old.
Based
on
the
use
pattern,
chronic
residential
exposure
to
residues
of
bifenazate
is
not
expected.
In
addition,
there
is
potential
for
chronic
dietary
exposure
to
bifenazate
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,
as
shown
in

3

3.
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).
In
its
objections
to
a
separate
bifenazate
tolerance
action,
NRDC
claims
that
residential
short­
and
intermediate­
term
risk
assessments
are
data
gaps
for
bifenazate.
In
the
current
risk
assessment,
EPA
calculated
short­
term
residential
risks
to
homeowner
applicators.
However,
the
Agency
concluded
that
no
significant
postapplication
exposure
is
aniticipated
from
landscape
ornamentals;
therefore,
no
residential
post­
application
assessment
was
conducted.
In
addition,
intermediate­
term
aggregate
exposure
(
30
days
to
6
months)
is
not
expected
since
homeowner
exposure
is
not
expected
to
exceed
1
to
30
days.
Bifenazate
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
bifenazate.
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
2,069
for
the
U.
S.
population;
2,418
for
youth
13
 
19
years
old;
2,429
for
adults
20
 
49
years
old;
2,467
for
females
13
 
49
years
old;
and
2,377
for
adults
50+
years
old.
These
aggregate
MOEs
do
not
exceed
the
Agency's
level
of
concern
for
aggregate
exposure
to
food
and
residential
uses.
In
addition,
short­
term
DWLOCs
were
calculated
and
compared
to
the
EECs
for
chronic
exposure
of
bifenazate
in
ground
and
surface
water.
After
calculating
DWLOCs
and
comparing
them
to
the
EECs
for
surface
and
ground
water,
EPA
does
not
expect
short­
term
aggregate
exposure
to
exceed
the
Agency's
level
of
concern,
as
shown
in

4.
Aggregate
cancer
risk
for
U.
S.
population.
Bifenazate
is
classified
as
not
likely
to
be
a
human
carcinogen.
The
Agency
concludes
that
bifenazate
is
not
expected
to
pose
a
cancer
risk
to
humans.
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,
and
to
infants
and
children
from
aggregate
exposure
to
bifenazate
residues.

IV.
Other
Considerations
A.
Analytical
Enforcement
Methodology
1.
Plant.
The
enforcement
method
for
plant
tolerances
associated
with
these
petitions
is
method
UCC
 
D2341,
which
uses
high
pressure
liquid
chromatography
with
an
oxidative
coulometric
electrochemical
detector.
2.
Livestock.
The
enforcement
method
for
animal
products
utilizes
high
pressure
liquid
chomatography
with
oxidative
coulometric
electrochemical
detection.
3.
Multiresidue
method.
Multiresidue
Enforcement
Method
Protocol
C
has
been
shown
to
be
adequate
for
enforcing
these
tolerances.
These
methods
may
be
requested
from:
Chief,
Analytical
Chemistry
Branch,
Environmental
Science
Center,
701
Mapes
Rd.,
Ft.
Meade,
MD

5350;
telephone
number:
(

305
 
2905;
e­
mail
address:
residuemethods@
epa.
gov.

B.
International
Residue
Limits
Canada,
Codex,
and
Mexico
do
not
have
maximum
residue
limits
(
MRLs)
for
residues
of
bifenazate
in/
on
the
proposed
crops.
Therefore,
harmonization
is
not
an
issue.

V.
Conclusion
Therefore,
tolerances
are
established
for
combined
residues
of
bifenazate,
and
diazinecarboxylic
acid;
2­(
4­
methoxy­
[
1,1'­
biphenyl]­
3­

VI.
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.

B.
When
Will
the
Agency
Grant
a
Request
for
a
Hearing?
A
request
for
a
hearing
will
be
granted
if
the
Administrator
determines
that
the
material
submitted
shows
the
following:
There
is
a
genuine
and
substantial
issue
of
fact;
there
is
a
reasonable
possibility
that
available
evidence
identified
by
the
requestor
would,
if
established
resolve
one
or
more
of
such
issues
in
favor
of
the
requestor,
taking
into
account
uncontested
claims
or
facts
to
the
contrary;
and
resolution
of
the
factual
issues(
s)
in
the
manner
sought
by
the
requestor
would
be
adequate
to
justify
the
action
requested
(
40
CFR
178.32).

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
tolerances
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

as
added
by

generally
provides
that
before

take
effect,
the
agency
promulgating
the
rule
must
submit
a
rule
report,
which
includes
a

to
each
House
of
the
Congress
and
to
the

of
the
