Rules
and
Regulations
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.

The
Congressional
Review
Act,

U.
S.
C.
801et
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

prior
to
publication
of

Background
and
Statutory
Findings
In
the
Federal
Register
of
October
6,
1999
(
64
FR
Page
54300
 
54303)
(
FRL
 
6029
 
9),
EPA
issued
a
notice
pursuant
to
section
408
of
FFDCA,
21
U.
S.
C.
346a,
as
amended
by
FQPA
(
Public
Law
104
 
170),
announcing
the
filing
of
a
pesticide
petition
(
PP
2F02609)
by
BASF
Corporation,
26
Davis
Drive,
P.
O.
Box
13528,
Research
Triangle
Park,
NC
27709
 
3528.
That
notice
included
a
summary
of
the
petition
prepared
by
BASF
Corporation,
the
registrant.
There
were
no
comments
received
in
response
to
the
notice
of
filing.
The
petition
requested
that
40
CFR
180.395
be
amended
by
establishing
a
tolerance
for
residues
of
the
insecticide
Hydramethylnon
in
or
on
pineapple
at
0.05
parts
per
million
(
ppm).
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
and
a
complete
description
of
the
risk
assessment
process,
see
the
final
rule

Tolerances

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
hydramethylnon
on
pineapple
at
0.05
ppm.
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
hydramethylnon
are
discussed
in
Table
1
of
this
unit
as
well
as
the
no­
observed­
adverse­
effectlevel
(
NOAEL)
and
the
lowest­
observedadverse
effect­
level
(
LOAEL)
from
the
toxicity
studies
reviewed.

B.
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
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.

summary
of
the
toxicological
endpoints
for
hydramethylnon
used
for
human
risk
assessment
is

The
Agency's
Cancer

determined
that
hydramethylnon
should
be
classified
as
a
Group

and
recommended
that,
for
the

approach
should
be

The
Cancer

report
was
issued
on

dose
endpoint
was
established
for
the
general
U.
S.
population
and
infants
and
children.
The
acute
dietary
exposure
estimates
are
well
below
the
Agency's
level
of
concern
(<
100%
aPAD)
at
the
95th
exposure
percentile
for
females
13
 
49
years
old
(<
1%
of
the
aPAD).
ii.
Chronic
exposure.
In
conducting
this
chronic
dietary
risk
assessment
the
Dietary
Exposure
Evaluation
Model
(
DEEM
 
)
analysis
evaluated
the
individual
food
consumption
as
reported
by
respondents
in
the
USDA
1994
 
1996/
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
Tier
1
(
conservative,
deterministic
assessment
using
tolerance­
level
residues,
and
100%
crop
treated
(
CT)
for
the
proposed
commodity;
and
DEEMFCID
 
ver.
1.30,
processing
factors
set
to
(
1)
a
chronic
dietary
exposure
assessment
was
conducted
for
the
general
U.
S.
population
and
various
population
subgroups.
The
chronic
dietary
exposure
estimates
are
well
below
the
Agency's
level
of
concern
(<
100%
cPAD)
for
the
general
U.
S.
population
(<
1%
of
the
cPAD)
and
all
population
subgroups.
iii.
Cancer.
In
a
chronic
feeding/
carcinogenicity
study
in
Charles
River
CD
rats,
no
compound­
related
clinical
signs
were
observed
and
survival
was
not
affected
by
treatment.
The
LOAEL
was
based
on
small,
soft
testes,
decreased
testicular
weights
(
27%),
and
testicular
atrophy
in
males;
and
decreased
body
weight
gain
in
females
(
22%).
Statistically
significant
findings
of
neoplasia
were
found
in
the
uterus
(
adenomatous
polyps)
and
adrenals
(
medullary
adenomas),
but
these
were
not
considered
toxicologically
significant
because
they
were
seen
at
doses
above
the
MTD.
In
an
18
month
carcinogenicity
feeding
study
in
Charles
River
CD­
1
mice,
survival
decreased
as
the
dose
increased,
but
not
enough
to
jeopardize
the
study.
The
LOAEL
was
based
on
testicular
degeneration
(
hypospermia,
interstitial
cell
hyperplasia
of
Leydig
cells,
and
germinal
cell
degeneration)
in
males,
and
combined
lung
adenomas
and
carcinomas
in
females.
Findings
of
hyperplasia
and
neoplasia
in
the
lungs
of
males
were
not
considered
toxicologically
significant
because
they
were
seen
at
doses
above
the
MTD.
Findings
in
females
of
statistically
significant
increases
in
lung
adenomas
and
combined
lung
adenomas/
carcinomas
were,
however,
considered
toxicologically
significant.
The
Agency's
Cancer
Peer
Review
Committee
classified
hydramethylnon
as
a
Group
C­
possible
human
carcinogen,
and
recommended
that,
for
the
purpose
of
risk
characterization,
the
Reference
Dose
approach
should
be
used
for
quantification
of
human
risk.
This
classification
was
based
upon
statistically
significant
increases
in
lung
adenomas
and
combined
lung
adenomas/
carcinomas
in
female
mice.
Dietary
risk
concerns
due
to
long­
term
consumption
of
hydramethylnon
residues
are
adequately
addressed
by
the
chronic
exposure
analysis
using
the
RfD.
iv.
Anticipated
residue
and
percent
crop
treated
(
PCT)
information.
Section
408(
b)(
2)(
F)
of
the
FFDCA
states
that
the
Agency
may
use
data
on
the
actual
percent
of
food
treated
for
assessing
chronic
dietary
risk
only
if
the
Agency
can
make
the
following
findings:
Condition
1,
that
the
data
used
are
reliable
and
provide
a
valid
basis
to
show
what
percentage
of
the
food
derived
from
such
crop
is
likely
to
contain
such
pesticide
residue;
Condition
2,
that
the
exposure
estimate
does
not
underestimate
exposure
for
any
significant
subpopulation
group;
and
Condition
3,
if
data
are
available
on
pesticide
use
and
food
consumption
in
a
particular
area,
the
exposure
estimate
does
not
understate
exposure
for
the
population
in
such
area.
In
addition,
the
Agency
must
provide
for
periodic
evaluation
of
any
estimates
used.
To
provide
for
the
periodic
evaluation
of
the
estimate
of
PCT
as
required
by
section
408(
b)(
2)(
F)
of
the
FFDCA,
EPA
may
require
registrants
to
submit
data
on
PCT.
A
routine
chronic
dietary
exposure
analysis
for
pineapple
was
based
on
100%
of
pineapple
crop
treated,
and
100%
of
grasses,
forage
(
pasture
and
rangeland)
treated
with
hydramethylnon.
The
Agency
believes
that
the
three
conditions
previously
discussed
have
been
met.
With
respect
to
Condition
1,
EPA
used
a
conservative,
model
assessment
as
outlined
in
Unit
III.
C.
1.
ii.
above,
using
tolerance­
level
residues
and
100%
CT
for
the
proposed
commodity
pineapple,
and
existing
commodities.
As
to
Conditions
2
and
3,
regional
consumption
information
and
consumption
information
for
significant
subpopulations
is
taken
into
account
through
EPA's
computer­
based
model
for
evaluating
the
exposure
of
significant
subpopulations
including
several
regional
groups.
Use
of
this
consumption
information
in
EPA's
risk
assessment
process
ensures
that
EPA's
exposure
estimate
does
not
understate
exposure
for
any
significant
subpopulation
group
and
allows
the
Agency
to
be
reasonably
certain
that
no
regional
population
is
exposed
to
residue
levels
higher
than
those
estimated
by
the
Agency.
Other
than
the
data
available
through
national
food
consumption
surveys,
EPA
does
not
have
available
information
on
the
regional
consumption
of
food
to
which
hydramethylnon
may
be
applied
in
a
particular
area.
2.
Dietary
exposure
from
drinking
water.
The
Agency
lacks
sufficient
monitoring
exposure
data
to
complete
a
comprehensive
dietary
exposure
analysis
and
risk
assessment
for
hydramethylnon
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
use
pattern,
physical
characteristics
and
environmental
fate
of
hydramethylnon.
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
screening
concentation
in
ground
water
(
SCI­
GROW)
model
is
used
to
predict
pesticide
concentrations
in
shallow
groundwater.
For
a
screening­
level
assessment
for
surface
water
EPA
will
use

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
and
an
index
reservoir
with
the
percent
crop
area
adjustment.
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
and
transformation
of
pesticides
from
the
source
water.
The
primary
use
of
these
models
by
the
Agency
at
this
stage
is
to
provide
an
initial
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
percent
of
reference
dose
or
percent
of
population
adusted
dose
(%
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
hydramethylnon
they
are
further
discussed
in
the
aggregate
risk
sections
in
Unit
III.
E.
Based
on
the
FIRST
and
SCI­
GROW
models
the
EECs
of
hydramethylnon
for
acute
exposures
are
estimated
to
be
76.09
parts
per
billion
(
ppb)
for
surface
water
and
0.035
ppb
for
ground
water.
The
EECs
for
chronic
exposures
are
estimated
to
be
1.45
ppb
for
surface
water
and
0.035
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).
Hydramethylnon
is
currently
registered
for
use
on
the
following
residential
non­
dietary
sites:
Hydramethylnon
is
used
as
a
bait
in
child
resistant
packaging
(
CRP)
and
as
a
gel
bait
to
control
ants
and
roaches
indoors,
and
as
a
granular
formulation
to
control
ants
in
yards
and
on
lawns.
It
is
also
applied
by
pest
control
operators
(
PCOs)
in
the
same
forms
for
indoor
and
outdoor
pest
control.
The
risk
assessment
was
conducted
using
the
following
residential
exposure
assumptions:
The
Agency
has
completed
a
non­
dietary
exposure
and
risk
assessment
for
hydramethylnon
including
the
following
uses:
residential
consumers
applying
granular
and
gel
formulations;
children
and
adults
contacting
recreational
turf
or
residential
lawns
treated
with
hydramethylnon;
and
toddlers'
incidental
nondietary
ingestion
of
products
applied
around
the
home.
Non­
occupational
handler
exposures
from
the
granular
formulations
applied
to
outdoor
residential
sites
are
assumed
to
be
short­
term
in
duration,
based
on
rapid
dissipation
and
insect
foraging.
No
chemical­
specific
data
were
submitted
for
the
registration
of
hydramethylnon
uses.
Per
an
Agency
policy,
non­
occupational
handler
assessments
are
based
on
surrogate
unit
exposures
from
the
draft
Standard
Operating
Procedures
(
SOPs)
for
Residential
Exposure
Assessments
(
12/
18/
97)
and
recommended
approaches
by
the
Agency's
Exposure
Science
Advisory
Committee
(
ExpoSAC).
Updates
to
the
Residential
SOPs
(
02/
01)
alter
the
residential
postapplication
scenario
assumptions.
These
updated
assumptions
are
expected
to
better
represent
residential
exposure
and
are
still
considered
to
be
high­
end,
screening
level
assumptions.
The
nonoccupational
handler
assessments
for
push
type
granular
spreaders
were
based
on
surrogate
unit
exposures
from
two
Outdoor
Residential
Exposure
Task
Force
(
ORETF)
studies.
The
ant
bait
stations
containing
hydramethylnon
are
in
child­
resistant
packaging
(
CRP).
The
bait
stations
are
supposed
to
be
placed
in
less
accessible
locations
such
as
in
or
under
kitchen
counters.
However,
handling
or
mouthing
of
the
bait
stations
is
the
most
commonly
reported
incidental
``
exposure''
to
hydramethylnon.
Such
exposures
involve,
at
most,
children
mouthing
the
bait
container
with
little
or
no
contact
with
the
actual
bait.
In
the
absence
of
an
applicable
acute
dietary
endpoint,
and
with
the
vast
majority
of
incident
data
resulting
in
little
or
no
health
effects,
no
quantitative
assessment
of
accidental
exposure
to
the
internal
contents
of
bait
stations
was
conducted.
The
gel
product
containing
hydramethylnon
is
supposed
to
be
applied
in
dime­
sized
portions
in
locations
inaccessible
to
children.
Accidental
ingestion
of
gel
from
such
application
is
considered
unlikely
and
was
therefore
not
assessed.
Adult
consumer
exposures
when
installing
and
removing
bait
stations
are
expected
to
be
minimal.
Consumer
exposure
when
applying
the
gel
compound
from
a
syringe
is
considered
negligible.
Limited
accessibility
(
i.
e.,
crack,
crevice,
behind
appliances,
in
crawl
spaces)
of
the
gel
and
granular
formulations
when
used
by
professional
applicators
in
the
home
make
it
unlikely
that
residents
would
be
exposed
to
these
formulations
indoors.
For
the
proposed
application
of
granules
to
outdoor
residential
sites,
dermal
MOEs
calculated
for
non­
occupational
handlers
were
10,000
or
greater.
Dermal
postapplication
exposure
from
lawns
treated
with
hydramethylnon
granules
at
the
maximum
application
rate
of
2.2
lb
product
per
acre
(
0.022
lb
ai/
A)
were
estimated
using
standard
assumptions,
as
no
chemical­
specific
residue
data
were
available.
For
adults
and
children
playing
actively
for
two
hours
on
a
just­
treated
lawn,
the
estimated
MOEs
were
41,000
and
24,000,
respectively.
The
aggregate
(
dermal,
hand­
mouth
and
object­
mouth)
MOE
for
a
15
kg
child
playing
on
a
lawn
was
4,000.
The
MOE
for
incidental
ingestion
of
3
mg
of
1%
hydramethylnon
granules
found
on
the
surface
of
the
lawn
was
850.
The
hydramethylnon
granules
are
formulated
as
small
granules
to
allow
for
ant
removal,
and
are
therefore
not
easily
noticed
by
a
child,
and
ingestion
is
unlikely.
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
hydramethylnon
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,
hydramethylnon
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
hydramethylnon
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

the
cumulative
effects
of
such
chemicals,

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.
The
Agency
has
concluded
that
there
is
no
concern
for
pre­
and/
or
postnatal
toxicity
resulting
from
exposure
to
hydramethylnon.
3.
Conclusion.
There
is
a
complete
toxicity
data
base
for
hydramethylnon
and
exposure
data
are
complete
or
are
estimated
based
on
data
that
reasonably
accounts
for
potential
exposures.
The
Agency
determined
that
no
special
FQPA
Safety
Factor
is
needed
(
1x)
for
hydramethylnon.
The
exposure
databases
(
dietary
food,
drinking
water,
and
residential)
are
complete
and
the
risk
assessment
for
each
potential
exposure
scenario
includes
all
metabolites
and/
or
degradates
of
concern
and
does
not
underestimate
the
potential
risk
for
infants
and
children.
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
liter
(
L)/
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
groundwater
are
less
than
the
calculated
DWLOCs,
EPA
concludes
with
reasonable
certainty
that
exposures
to
the
pesticide
in
drinking
water
(
when
considered
along
with
other
sources
of
exposure
for
which
EPA
has
reliable
data)
would
not
result
in
unacceptable
levels
of
aggregate
human
health
risk
at
this
time.
Because
EPA
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,
EPA
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
hydramethylnon
will
occupy
<
1%
of
the
aPAD
for
females
13
years
and
older.
In
addition,
there
is
potential
for
acute
dietary
exposure
to
hydramethylnon
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,
as
shown
in
the
following
Table
3:

2.
Chronic
risk.
Using
the
exposure
assumptions
described
in
this
unit
for
chronic
exposure,
EPA
has
concluded
that
exposure
to
hydramethylnon
from
food
will
utilize
<
1%
of
the
cPAD
for
the
U.
S.
population,
and
<
1%
(
0.02%)
of
the
cPAD
for
children
1
 
2
years
old.
Based
on
the
use
pattern,
chronic
residential
exposure
to
residues
of
hydramethylnon
is
not
expected.
In
addition,
there
is
potential
for
chronic
dietary
exposure
to
hydramethylnon
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,

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).
Hydramethylnon
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
hydramethylnon.
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
exposures
for
both
adults
(
MOE
=
8,000;
handler
and
post­
application)
and
children
(
MOE
=
680;
post­
application).
Therefore,
the
turf­
treatment
exposure
estimates
were
aggregated
with
the
chronic
dietary
(
food)
to
provide
a
worst­
case
estimate
of
short­
term
aggregate
risk
for
the
U.
S.
population
and
children
1
 
2
years
old
(
the
child
population
subgroup
with
the
highest
estimated
average
(
chronic)
dietary
food
exposure).
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
hydramethylnon
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
the
following

5:

4.
Intermediate­

risk.
Intermediate­
term
aggregate
exposure
takes
into
account
residential
exposure
plus
chronic
exposure
to
food
and
water
(
considered
to
be
a
background
exposure
level).
Though
residential
exposure
could
occur
with
the
use
of
hydramethylnon,
an
intermediate­
term
aggregate
risk
assessment
was
not
performed
because
it
is
based
on
the
same
toxic
endpoint
and
dose
as
the
short­
term,
and
the
higher
exposure
used
in
the
short­
term
assessment
represents
a
worse
case.
5.
Aggregate
cancer
risk
for
U.
S.
population.
A
separate
cancer
aggregate
risk
assessment
was
not
performed
because
the
Reference
Dose
approach
was
recommended
for
quantification
of
human
risk.
Cancer
risks
are
adequately
addressed
by
the
chronic
aggregate
and
assessment
which
used
the
chronic
reference
dose
(
cRfD).
6.
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
hydramethylnon
residues.

IV.
Other
Considerations
A.
Analytical
Enforcement
Methodology
The
method
presented
by
BASF
Corporation
and
designated
M
2458,
is
the
predecessor
to
method
M
2458.01
for
which
BASF
Corporation
has
submitted
as
an
independent
method
validation.
The
updated
method
corrects
some
typographical
errors
and
clarifies
some
of
the
fractionation
steps.
Adequate
enforcement
methodology
(
example
 
gas
chromatography)
is
available
to
enforce
the
tolerance
expression.
The
method
may
be
requested
from:

B.
International
Residue
Limits
No
maximum
residue
limits
for
hydramethylnon
in/
on
pineapple
have
been
established
or
proposed
by
Codex,
Canada,
or
Mexico
for
any
agricultural
commodity;
therefore,
no
compatibility
concerns
exist
with
respect
to
U.
S.
tolerances.

C.
Conditions
The
following
studies
are
required
to
further
characterize
the
environmental
effects
of
hydramethylnon:
Estuarine/
marine
fish
LC50
(
72
 
1),
Estuarine/
marine
invertebrate
EC50
(
72
 
2),
and
Sediment
Toxicity
Testing
(
Harmonized
guidelines
850.1735
and
850.1740).
In
addition,
the
following
studies
are
required
for
any
future
expansion
of
hydramethylnon
uses:
Aquatic
Photodegradation
(
161
 
2),
Aerobic
Aquatic
Metabolism
(
162
 
4),
and
Terrestrial
Field
Dissipation
(

Recommendation
for
Tolerances
The
residue
chemistry
and
toxicological
databases
support
the
requested
tolerance
of
0.05
ppm
for
hydramethylnon
on
pineapple.
The
Agency
has
also
previously
recommended
that
the
grass
(
pasture
and
rangeland)
tolerance
be
increased
to
2.0
ppm
and
the
grass
hay
(
pasture
and
rangeland)
tolerance
be
increased
to
0.1
ppm
(
Hydramethylnon
RED,
EPA
738
 
R
 
98
 
023,
12/
98).

V.
Conclusion
Therefore,
the
tolerance
is
established
for
residues
of
hydramethylnon,
in
or
on
pineapple
at
0.05
ppm.,
and
revised
for
grass
(
pasture
and
rangeland)
at
2.0
ppm,
and
grass
hay
(
pasture
and
rangeland)
at
0.1
ppm
respectively.

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.

seq.,

any

Rules
and
Regulations
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.

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

containing
this
rule
and
other
required
information
to
the
U.

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).
