Rules
and
Regulations
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
FFDCA
section
408(
n)(
4).
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.

generally
provides
that
before
a
rule
may
take
effect,
the

promulgating
the
rule
must
submit
a
rule
report,
which
includes

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)
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)
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.

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
clopyralid
are
discussed
in
the
following
Table
1
and
Table
2
as
well
as
the
no
observed
adverse
effect
level
(NOAEL)
and
the
lowest
observed
adverse
effect
level
(LOAEL)
from
the
toxicity
studies
reviewed.

Toxicological
Endpoints
The
dose
at
which
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
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
factor
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
Safety
Factor.
For
non­
dietary
risk
assessments
(other
than
cancer)
the

is

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.

Exposure
Assessment
1.
Dietary
exposure
from
food
and
feed
uses.
Tolerances
have
been
established
(40
CFR
180.431)
for
the
residues
of
clopyralid,
in
or
on
a
variety
of
raw
agricultural
commodities.
Established,
proposed
and
increased
tolerances
for
clopyralid
are
adequate
for
any
expected
secondary
residues
in
meat,
milk,
poultry
and/
or
eggs.
Risk
assessments
were
conducted
by
EPA
to
assess
dietary
exposures
from
clopyralid
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
one
day
or
single
exposure.
In
conducting
this
acute
dietary
risk
assessment
the
Dietary
Exposure
Evaluation
Model
(DEEM
TM
)
analysis
evaluated
the
individual
food
consumption
as
reported
by
respondents
in
the
USDA
1989–
1992
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
acute
exposure
assessments.
Residue
levels
are
at
the
recommended
tolerances
with
the
exception
of
sugar
beets.
The
empirical
processing
factor
of
0.1x
was
used
for
sugar­
beet
representing
the
10–
fold
reduction
in
residues
for
refined
sugar.
One
hundred
percent
of
all
of
the
crops
are
treated
with
clopyralid.

Cancer.

and

studies
show
no
evidence
of

Clopyralid
is
classified
as
not
likely
to
be
a
human
carcinogen.
2.
Dietary
exposure
from
drinking
water.
The
Agency
lacks
sufficient
monitoring
exposure
data
to
complete
a
comprehensive
dietary
exposure
analysis
and
risk
assessment
for
clopyralid
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
clopyralid.
The
Agency
uses
the
Generic
Estimated
Environmental
Concentration
(GENEEC)
or
the
Pesticide
Root
Zone
Model/
Exposure
Analysis
Modeling
System
(PRZM/
EXAMS)
to
estimate
pesticide
concentrations
in
surface
water
and
SCI­
GROW,
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
high­
end
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
clopyralid
they
are
further
discussed
in
the
aggregate
risk
sections
in
Unit
III.
E
of
this
document.
Based
on
the
FIRST
and
SCI­
GROW
models
the
estimated
environmental
concentrations
(EECs)
of
clopyralid
for
acute
exposures
are
estimated
to
be
46
parts
per
billion
(ppb)
for
surface
water
and
9.7
ppb
for
ground
water.
The
EECs
for
chronic
exposures
are
estimated
to
be
18
ppb
in
surface
water
and
9.7
ppb
for
ground
water.
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).
Clopyralid
is
currently
registered
for
use
on
the
following
residential
nondietary
sites:
Turf
and
ornamentals
(including
golf
courses).
The
risk
assessment
was
conducted
using
the
following
residential
exposure
assumptions:
the
75
mg/
kg/
day
NOAEL
was
used
in
the
short­
term
inhalation,
hand­
to­
mouth,
and
episodic
granular
ingestion
risk
assessments
of
the
residential
exposure.
The
intermediateterm
assessment
for
children's
hand­
tomouth
exposure
was
based
on
the
15
mg/
kg/
day
NOAEL
chosen
for
incidental
oral
exposure.
As
no
dermal
endpoint
was
selected,
a
dermal
risk
assessment
was
not
required
for
residential
exposure.
For
residential
oral
and
inhalation
risk
assessments,
the
target
margin
of
exposure
(MOE)
was
100
which
incorporates
the
removal
of
the
FQPA
Safety
Factor.
MOEs
calculated
for
residential
handler's
inhalation
exposure
and
children's
oral
exposures
were
well
above
the
target
of
100;
and
therefore,
do
not
exceed
the
Agency's
level
of
concern.
4.
Cumulative
exposure
to
substances
with
a
common
mechanism
of
toxicity.
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
``

that
have
a
common

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

Safety
Factor
for
Infants
and
Children
1.
In
general.
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
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.
No
increased
quantitative
or
qualitative
susceptibility
was
seen
following
pre­
and/
or
post­
natal
exposures.
In
the
developmental
study
with
rats,
no
developmental
toxicity
was
seen
at
the
HDT
(250
mg/
kg/
day)
even
in
the
presence
of
severe
maternal
toxicity
which
manifested
as
deaths,
reduced
body
weight
gain
and
decreased
food
consumption.
In
the
two

reproduction
study,

toxicity,
characterized
as
decreased
pup
weight
and
increased

occurred
only
at
the

(1,500
mg/

which
is
higher
than
the
Limit
Dose
(1,000
mg/

parental
toxicity
(decreased

and
slight
focal
hyper

of
the
gastric
mucosa).
In
the
developmental
rabbit
study,
hydrocephalus
was
seen
in
eight
fetuses
(3/
15
litters)
only
at
the
highest
dose
tested
(250
mg/
kg/
day)
in
the
presence
of
severe
maternal
toxicity
that
manifested
as
death,
decreases
in
mean
body
weight
and
lesions
of
the
gastric
mucosa;
the
developmental
NOAEL
was
110
mg/
kg/
day.
The
available
data
indicate
that
a
developmental
neurotoxicity
study
would
have
to
be
tested
at
dose
levels
higher
than
250
mg/
kg/
day
because
no
developmental
toxicity
was
observed
in
rats
at
250
mg/
kg/
day.
In
addition,
the
offspring
NOAEL
in
the
two
generation
reproduction
study
was
500
mg/
kg/
day
with
a
LOAEL
of
1,500
mg/
kg/
day.
Therefore,
it
is
anticipated
that
in
order
to
elicit
any
fetal
nervous
system
abnormalities
in
a
developmental
neurotoxicity
study,
the
selected
dose
levels
would
have
to
be
higher
than
500
mg/
kg/
day.
Since
the
dose
level
selections
for
the
developmental
neurotoxicity
study
will
be
greater
than
500
mg/
kg/
day,
the
resultant
NOAEL
will
be
either
comparable
to,
or
higher
than
the
doses
currently
used
in
the
risk
assessment.
The
NOAEL
of
75
mg/
kg/
day
selected
for
the
acute
RfD
is
seven
times
lower
than
the
offspring
NOAEL
in
the
reproduction
study.
The
NOAEL
of
15
mg/
kg/
day
selected
for
the
chronic
RfD
and
the
residential
exposure
risk
assessments
is
thirty
three
times
lower
than
the
offspring
NOAEL
in
the
reproduction
study.
Therefore,
a
developmental
neurotoxicity
study
would
not
likely
change
the
regulatory
doses
used
for
overall
risk
assessments.
3.
Conclusion.
EPA
determined
that
an
additional
factor
to
protect
infants
and
children
was
not
appropriate.
Several
factors
influenced
this
decision
not
to
require
a
development
neurotoxicity
(DNT)
study:
i.
Although
hydrocephalus
was
observed
at
the
high
dose
in
the
developmental
rabbit
study,
it
was
seen
in
the
presence
of
severe
maternal
toxicity;
ii.
No
alterations
to
the
fetal
nervous
system
were
seen
in
the
developmental
rat
study
at
the
same
dose
(250
mg/
kg/
day);
iii.
There
was
no
quantitative
or
qualitative
evidence
of
increased
susceptibility
in
the
two
generation
reproduction
study;
iv.
There
is
no
concern
nor
are
there
residual
uncertainties
for
pre
and/
or
post
natal
toxicity;
and
v.
Although
there
are
no
acute
or
subchronic
neurotoxicity
studies,
there
is
no
evidence
of
neurotoxicity
or
neuropathology
in
adult
animals
in
any
of
the
studies.
EPA
decided
that
the
FQPA
safety
factor
should
be
reduced
to
1
rather
than
the
statutory
default
factor
of
10
because
the
existing
toxicology
database,
which
is
complete,
revealed
no
quantitative
or
qualitative
evidence
of
increased
susceptibility
following
in
utero
exposure
to
rats
and
rabbits
and/
or
following
prenatal/
postnatal
exposure
to
rats;
and
dietary
(food
and
drinking
water)
and
residential
exposure
assessments
will
not
underestimate
the
potential
exposures
for
infants,
children,
and/
or
women
of
childbearing
age
from
the
use
of
clopyralid.

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:
2L/
70
kg
(adult
male),
2L/
60
kg
(adult
female),
and
1L/
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
ground
water
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.
Using
the
exposure
assumptions
discussed
in
this
unit
for
acute
exposure,
the
acute
dietary
exposure
from
food
to
clopyralid
will
occupy
4%
of
the
aPAD
for
the
U.
S.
population,
2%
of
the
aPAD
for
females
13
years
and
older,
4%
of
the
aPAD
for
all
infants
(
1
year)
and
7%
of
the
aPAD
for
children
1–
6
years.
In
addition,
there
is
potential
for
acute
dietary
exposure
to
clopyralid
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
aPAD,

2.
Chronic
risk.
Using
the
exposure
assumptions
described
in
this
unit
for
chronic
exposure,
EPA
has
concluded
that
exposure
to
clopyralid
from
food
will
utilize
7%
of
the
cPAD
for
the
U.
S.
population,
7%
of
the
cPAD
for
all
infants
(
1
year)
and
17%
of
the
cPAD
for
children
1–

years.
Based
on
the
use
pattern,
chronic
residential
exposure
to
residues
of
clopyralid
is
not
expected.
In
addition,
there
is
potential
for
chronic
dietary
exposure
to
clopyralid
in
drinking
water.
After
calculating
DWLOCs
and
comparing
them
to
the
EECs
for
surface

EPA
does
not

Short­

Short­

aggregate
exposure
takes
into
account
residential
exposure
plus
chronic
exposure
to
food
and
water
(considered
to
be
a
background
exposure
level).
Clopyralid
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
clopyralid.
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
7,000
(U.
S.
population,
food
and
residential),
9,600
(females
13–

food
and
residential)
and
2,200
(children

These
aggregate
MOEs
do
not
exceed
the
Agency's
level
of
concern
for
aggregate
exposure
to
food
and
residential
uses.
In
addition,
shortterm
DWLOCs
were
calculated
and
compared
to
the

for
chronic
exposure
of
clopyralid
in

(considered

Clopyralid
is
currently

result
in
an
aggregate
MOE
of
530
(children

EPA
concludes
that
there

to
the
general

and
to
infants
and

Other
Considerations
A.
Analytical
Enforcement
Methodology
An
adequate
residue
analytical
method
is
available
for
enforcement
of
the
proposed
tolerances.
This
method,
ACR
75.6,
determines
clopyralid
as
the
methyl
ester
by
gas
chromatography
using
electron
capture
detection.
This
method
has
been
successfully
validated
by
EPA
and
has
been
published
in
FDA's
Pesticide
Analytical
Manual,
VolII
(PAM
II).
An
adequate
residue
analytical
method
is
also
available
for
the
enforcement
of
the
proposed
tolerance
on
animal
commodities.
This
method,
ACR
86.1,
determines
clopyralid
as
the
methyl
ester
by
gas
chromatography
using
electron
capture
detection.
This
method
has
been
successfully
validated
by
EPA
and
has
been
published
in
FDA's

B.
International
Residue
Limits
There
are
no
Codex
or
Mexican
maximum
residue
limits
(MRLs).
Canada
has
set
maximum
residue
limits
of
2.0
ppm
for
barley,
oats,
and
wheat,
7.0
ppm
for
the
milled
fractions
of
barley,
oats,
and
wheat
(excluding
flour),
1.0
ppm
for
strawberries
and
0.2
ppm
for
flax.

V.

Therefore,
tolerances
are
established
for
residues
of
clopyralid
on
strawberry
at
1.0
ppm;
hop,
dried

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
of
1996,
EPA
will
continue
to
use
those
procedures,
with
appropriate
adjustments,
until
the
necessary
modifications
can
be
made.
The
new
section
408(
g)
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),
as
was
provided
in
the
old
FFDCA
sections
408
and
409.
However,
the
period
for
filing
objections
is
now
60
days,
rather
than
30
days.

A.

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.
Regulatory
Assessment
Requirements
This
final
rule
establishes
a
tolerance
under
FFDCA
section
408(
d)
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
FFDCA
section
408(
d),
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
FFDCA
section
408(
n)(
4).
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.
Submission
to
Congress
and
the
Comptroller
General
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).

ACTION:
Notice
of
final

on
the
State
of

SUMMARY:
The
State
of
Hawaii
has
applied
for
approval
of
its
Underground
Storage
Tank
Program
for
petroleum
and
hazardous
substances
under
Subtitle
I
of
the
Resource
Conservation
and
Recovery
Act
(RCRA).
The
Environmental
Protection
Agency
(EPA)
has
reviewed
Hawaii's
application
and
has
reached
a
final
determination
that
Hawaii's
Underground
Storage
Tank
Program
for
petroleum
and
hazardous
substances
satisfies
all
of
the
requirements
necessary
to
qualify
for
approval.
Thus,
the
EPA
is
granting
final
approval
to
the
State
of
Hawaii
to
operate
its
Underground
Storage
Tank
Program
for
petroleum
and
hazardous
substances.

EFFECTIVE
DATE:
Final
approval
for
the
State
of
Hawaii's
Underground
Storage

shall
be
effective
on
September

SUPPLEMENTARY
INFORMATION:

A.
Background
Section
9004
of
the
Resource
Conservation
and
Recovery
Act
(RCRA)
authorizes
the
Environmental
Protection
Agency
(EPA)
to
approve
state
Underground
Storage
Tank
Programs
to
operate
in
the
State
in
lieu
of
the
Federal
Underground
Storage
Tank
(UST)
Program.
To
qualify
for
final
authorization,
a
state's
Program
must:
(1)
Be
``
no
less
stringent''
than
the
Federal
Program
for
the
seven
elements
set
forth
at
RCRA
Section
9004(
a)(
1)
through
(7);
and
(2)
provide
for
adequate
enforcement
of
compliance
with
the
UST
standards
of
RCRA
Section
9004(
a).
Note
that
RCRA
Sections
9005
(on
information­
gathering)
and
9006
(on
Federal
enforcement)
by
their
terms
apply
even
in
states
with
Programs
approved
by
the
EPA
under
RCRA
Section
9004.
Thus,
the
Agency
retains
its
authority
under
RCRA
Sections
9005
and
9006,
42
U.
S.
C.
6991d
and
6991e,
and
other
applicable
statutory
and
regulatory
provisions
to
undertake
inspections
and
enforcement
actions
in
approved
states.
With
respect
to
such
an
enforcement
action,
the
Agency
will
rely
on
Federal
sanctions,
Federal
inspection
authorities,
and
Federal
procedures
rather
than
the
state
authorized
analogues
to
these
provisions.
Moreover,
authorization
of
a
state
Program
is
a
prospective
action
only
and
an
authorized
state
Program
only
operates
in
lieu
of
the
Federal
Program
as
of
the
effective
date
of
the
authorization.
The
Agency
may
undertake
enforcement
of
the
Federal
requirements
for
violations
of
those
Federal
requirements
which
occurred
prior
to
the
effective
date
of
authorization
of
the
state's
Program.
In
this
case,
authorization
of
the
Hawaii
UST
Program
will
be
effective
on
September
30,
2002.
On
May
23,
2001,
the
State
of
Hawaii
submitted
an
official
application
to
obtain
final
program
approval
to
administer
the
Underground
Storage
Tank
Program
for
petroleum
and
hazardous
substances.
On
October
5,
2001,
the
EPA
published
a
tentative
decision
announcing
its
intent
to
grant
Hawaii
final
approval.
Further
background
on
the
tentative
decision
to
grant
approval
appears
at
66
FR
50963–
50966,
October
5,
2001.
Along
with
the
tentative
determination,
the
EPA
announced
the
availability
of
the
application
for
public
comment
and
the
date
of
a
public
hearing
on
the
application.
The
EPA
requested
advance
notice
for
testimony
and
reserved
the
right
to
cancel
the
public
hearing
for
lack
of
public
interest.
The
hearing
was
held
at
Kawananakoa
Middle
School
in
Honolulu,
Hawaii
on
November
13,
2001.
