Notices
In
reviewing
delegation
requests,
EPA's
role
is
to
approve
state
capabilities,
provided
that
they
meet
the
criteria
of
the
Clean
Air
Act.
In
this
context,
in
the
absence
of
a
prior
existing
requirement
for
the
State
to
use
voluntary
consensus
standards
(
VCS),
EPA
has
no
authority
to
disapprove
a
delegation
request
for
failure
to
use
VCS.
It
would
thus
be
inconsistent
with
applicable
law
for
EPA,
when
it
reviews
a
delegation
request,
to
use
VCS
in
place
of
a
delegation
request
that
otherwise
satisfies
the
provisions
of
the
Clean
Air
Act.
Thus,
the
requirements
of
section
12(
d)
of
the
National
Technology
Transfer
and
Advancement
Act
of
1995
(
15
U.
S.
C.

note)
do
not
apply.
This
rule
does
not
impose
an
information
collection
burden
under
the
provisions
of
the
Paperwork
Reduction
Act
of
1995
(
44
U.
S.
C.

et
seq.).

A.
Residue
Chemistry
1.
Plant
metabolism.
The
metabolic
profile
of
buprofezin
has
been
elucidated
in
a
wide
range
of
crops,
including
tomatoes,
lettuce,
cotton,
and
citrus.
In
tomatoes,
lettuce,
and
cotton
unchanged
buprofezin
was
the
only
significant
residue.
In
citrus,
besides
buprofezin,
the
principal
polar
residue
is
a
hexose
conjugate
of
BF4
(
buprofezin
hydroxylated
in
the
t­
butyl
group),
which
was
resistant
to
enzyme
hydrolysis.
With
acid
hydrolysis
of
the
polar
fraction,
BF26
was
released,
with
minor
amounts
of
BF9
and
BF12.
The
same
compounds
were
observed
following
acid
hydrolysis
of
a
standard
of
BF4,
which
clearly
indicates
that
BF4
is
the
conjugated
metabolite
existing
in
citrus.
Although
only
limited
metabolism
was
observed
in
lettuce
and
cotton,
trace
levels
of
BF4/
BF26,
BF9,
and
BF12
were
observed
indicating
that
the
metabolic
pathway
does
not
differ
with
plant
species.
2.
Analytical
method.
Metabolism
studies
on
lettuce
and
tomatoes
have
shown
that
the
only
significant
residue
in
these
crops
is
buprofezin.
Development
of
the
analytical
method
took
place
in
parallel
with
the
metabolism
studies
and
the
method
was
designed
to
quantify
two
metabolites
(
BF9
and
BF12)
in
addition
to
the
parent
compound.
This
method
was
used
for
analysis
of
samples
from
the
field
trials
on
all
crops
except
citrus,
but
for
tolerance
enforcement
only
the
parent
compound
is
considered.
3.
Magnitude
of
residues.
The
magnitude
of
residues
is
adequately
understood
and
supports
the
proposed
tolerances.

B.
Toxicological
Profile
1.
Acute
toxicity.
An
assessment
of
toxic
effects
caused
by
buprofezin
is
discussed
in
Unit
III.
A.
and
Unit
III.
B.
of
the
Federal
Register
dated
September
5,
2001
(
66
FR
46382)
(
FRL
 
6796
 
6).
2.
Animal
metabolism.
The
metabolism
of
buprofezin
has
been
extensively
studied
in
various
species
of
animals
and
fish.
Buprofezin
has
several
groups
that
can
metabolize
in
a
variety
of
ways
thus
potentially
producing
a
very
large
number
of
metabolites.
Indeed
extensive
metabolism
to
many
minor
metabolites
was
observed
in
all
the
animal
species.
Metabolism
in
fish
was,
however,
much
more
limited
and
clearly
defined.
Although
not
all
metabolic
intermediates
have
been
detected
in
all
the
species,
the
major
routes
of
metabolism
have
been
identified
in
animals
and
fish
and
a
consistent
pattern
is
observed
throughout
these
species.
The
proposed
metabolic
pathway
was
provided
in
the
tolerance
petition,
PP
0F6087.
For
convenience,
degradates
are
referred
to
by
an
internal
code:
BF
1
through
13.
Corresponding
chemical
structures
were
provided
in
the
tolerance
petition,
PP
0F6087.
3.
Endocrine
disruption.
No
special
studies
have
been
conducted
to
investigate
the
potential
of
buprofezin
to
induce
estrogenic
or
other
endocrine
effects.
The
standard
battery
of
required
toxicity
studies
has
been
completed.
These
studies
include
an
evaluation
of
the
potential
effects
on
reproduction
and
development
and
an
evaluation
of
the
pathology
of
the
endocrine
organs
following
repeated
or
long­
term
exposure.
These
studies
are
generally
considered
to
be
sufficient
to
detect
any
endocrine
effects.
The
only
effect
noted
on
endocrine
organs
was
an
increased
incidence
of
follicular
cell
hypertrophy
and
C­
cell
hyperplasia
of
the
thyroid
gland
in
rats
administered
buprofezin
at
dietary
concentrations
of
2,000
ppm
for
24
months.
Buprofezin
also
caused
mild
to
moderate
hepatotoxic
effects
at
this
dietary
concentration.
Nichino
America,
Inc.
believes
that
the
effect
on
the
thyroid
most
likely
resulted
from
increased
turnover
of
T3/
T4
in
the
liver
with
a
resultant
rise
in
TSH
secretion
(
due
to
the
hepatotoxicity).
The
rat
is
known
to
be
much
more
susceptible
than
humans
to
these
effects
due
to
the
very
rapid
turnover
of
thyroxine
in
the
blood
in
rats
(
12
hours
versus
about
5
to
9
days
in
humans).
Therefore,
the
thyroid
pathological
changes
which
have
been
noted
following
administration
of
high
doses
of
buprofezin
are
considered
to
be
of
minimal
relevance
to
human
risk
assessment,
particularly
considering
the
low
levels
of
buprofezin
to
which
humans
are
likely
to
be
exposed.

C.
Aggregate
Exposure
1.
Dietary
exposure
 
i.
Food.
Chronic
dietary
exposure
was
estimated
using
Dietary
Exposure
Evaluation
Model
(
DEEMTM)
tolerance
levels,
and
100%
crop
treated,
except
for
tomatoes
with
40%
of
the
crop
treated.
The
chronic
dietary
exposure
to
the
U.
S.
population
(
total)
was
estimated
as
0.001229
milligrams/
kilogram/
body
weight/
day
(
mg/
kg
bwt/
day),
and
was
37%
of
the
estimated
reference
dose
(
RfD).
Exposure
to
children
ages
1
to
6,
the
highest
exposed
population
subgroup,
was
0.002393
mg/
kg
bwt/
day
(
73%
of
the
estimated
RfD).
ii.
Drinking
water.
The
residue
of
concern
in
drinking
water
was
determined
to
be
buprofezin.
The
potential
exposure
of
buprofezin
in
drinking
water
abstracted
from
surface
water
was
assessed
using
a
Tier
2,
modeling
approach.
EPA's
Pesticide
Root
Zone
Model
(
PRZM)
was
used
to
generate
potential
runoff
loads
from
a
standardized
agricultural
field
(
10
 
hectare
(
ha))
to
a
standardized
aquatic
system
(
1
 
ha
2
 
meters
(
m)
deep
pond)
following
application
of
buprofezin
to
citrus
(
the
maximum
proposed
use
rate
for
all
crops).
Exposure
Analysis
Modeling
Systems
(
EXAMS)
was
used
to
estimate
the
exposure
concentration
in
surface
water.
The
``
once­
in­
10
 
year''
exceedance
probability
corresponded
to
a
concentration
at
0.52
part
per
billion
(
ppb).
This
value
refers
to
the
56
 
day
average
estimated
concentration
in
a
farm
pond
draining
agricultural
land
and
must
be
considered
a
gross
overestimate
of
concentrations
of
buprofezin

2.
Non­
dietary
exposure.
Food
uses
described
in
these
petitions
are
strictly
agricultural
and
will
not
add
to
any
residential
non­
dietary
exposure
that
may
exist.

D.
Cumulative
Effects
Section
408(
b)(
2)(
D)(
v)
requires
that
the
Agency
must
consider
``
available
information''
concerning
the
cumulative
effects
of
a
particular
pesticide's
residue
and
``
other
substances
that
have
a
common
mechanism
of
toxicity.''
Available
information
in
this
context
include
not
only
toxicity,
chemistry,
and
exposure
data,
but
also
scientific
policies
and
methodologies
for
understanding
common
mechanisms
of
toxicity
and
conducting
cumulative
risk
assessments.
For
most
pesticides,
although
the
Agency
has
some
information
in
its
files
that
may
turn
out
to
be
helpful
in
eventually
determining
whether
a
pesticide
shares
a
common
mechanism
of
toxicity
with
any
other
substances,
EPA
does
not
at
this
time
have
the
methodologies
to
resolve
the
complex
scientific
issues
concerning
common
mechanism
of
toxicity
in
a
meaningful
way.
At
the
present
time,
there
are
insufficient
data
available
to
allow
Nichino
America,
Inc.
to
properly
evaluate
the
potential
for
cumulative
effects
with
other
pesticides
to
which
an
individual
may
be
exposed.
For
the
purposes
of
this
assessment,
therefore,
Nichino
America,
Inc.
has
assumed
that
buprofezin
does
not
have
a
common
mechanism
of
toxicity
with
any
other
registered
pesticides.
Therefore,
only
exposure
from
buprofezin
is
being
addressed
at
this
time.

E.
Safety
Determination
1.
U.
S.
population
 
i.
Acute
risk.
To
estimate
acute
aggregate
exposure
risk,
the
Agency
combined
the
high­
end
value
from
food
and
water
and
compared
it
to
the
acute
population
adjusted
dose
(
aPAD).
Using
the
exposure
assumptions
discussed
in
this
unit
for
acute
exposure,
the
acute
dietary
exposure
from
food
to
buprofezin
will
occupy
4%
of
the
aPAD
for
females
13
years
and
older
(
no
endpoint
was
identified
for
the
general
population
including
infants
and
children).
In
addition,
there
is
potential
for
acute
dietary
exposure
to
buprofezin
in
drinking
water.
After
calculating
drinking
water
levels
of
concern
(
DWLOCs)
and
comparing
them
to
the
estimated
environmental
concentrations
(
EECs)
for
surface
water
and
ground
water,
EPA
does
not
expect
the
aggregate
exposure
to
exceed
100%
of
the
aPAD.
ii.
Chronic
risk.
Based
on
the
toxicology
data
base
and
available
information
on
anticipated
residues,
chronic
dietary
exposure
to
the
U.
S.
population
(
total)
was
37%
of
the
RfD.
Exposure
to
potential
residues
in
drinking
water
is
expected
to
be
negligible,
as
DWLOCs
are
substantially
higher
than
modeled
acute
and
longterm
EECs.
The
margin
of
exposure
(
MOE)
from
the
limited
potential
for
short­
term
exposure
from
residential
uses
was
>
1,000.
Based
on
these
assessments,
it
can
be
concluded
that
there
is
reasonable
certainty
of
no
harm
to
the
U.
S.
population
or
any
population
subgroup
from
exposure
to
buprofezin.
iii.
Aggregate
cancer
risk
for
the
U.
S.
population.
In
accordance
with
EPA
Guidelines
for
Carcinogen
Risk
Assessment
(
proposed
July
1999),
the
Agency's
Cancer
Assessment
Review
Committee
has
classified
buprofezin
as
having
suggestive
evidence
of
carcinogenicity,
but
not
sufficient
to
assess
human
carcinogenic
potential,
and
further
recommended
that
no
quantification
of
cancer
risk
is
required.
2.
Infants
and
children.
The
chronic
dietary
exposure
was
29%
of
the
RfD
for
infants
and
72%
of
the
RfD
for
children
ages
1
to
6.
Exposure
to
potential
residues
in
drinking
water
is
expected
to
be
negligible,
as
DWLOCs
are
substantially
higher
than
modeled
acute
and
long­
term
EECs.
The
MOE
from
the
limited
potential
for
short­
term
exposure
from
residential
uses
was
>
1,000.
Based
on
these
assessments,
it
can
be
concluded
that
there
is
reasonable
certainty
of
no
harm
to
infants
and
children
from
exposure
to
buprofezin.
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
buprofezin
residues.
