Electronically.
If
you
submit
an
electronic
comment
as
prescribed
in
this
unit,
EPA
recommends
that
you
include
your
name,
mailing
address,
and
an
email
address
or
other
contact
information
in
the
body
of
your
comment.
Also
include
this

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

as
part
of
the
comment
that
is

public
docket,
and
made
available
in
EPA's

docket.
If
EPA
cannot
read
your
comment
due
to
technical
difficulties
and
cannot
contact
you
for
clarification,
EPA
may
not
be
able
to

This
is
a
revised
notice
of
filing
to

a
previous
notice
of
filing
published
in
the

of
August

to
propose
permanent
tolerances,
instead
of
the
current
timelimited
tolerances
for
prosulfuron.

A.
Residue
Chemistry
1.
Plant
metabolism.
The
nature
of
the
residue
of
prosulfuron
in
corn
is
adequately
understood.
Significant
pathways
involve
oxidation
of
the
phenyl
ring
to
give
5
 
hydroxy
prosulfuron,
which
is
followed
by
sugar
conjugation.
Hydrolytic
cleavage
of
the
sulfonylurea
bridge
occurs
for
both
prosulfuron
and
5
 
hydroxy
prosulfuron,
yielding
the
corresponding
sulfonamide
and
triazine
amine
moieties.
The
sulfonamide
metabolites
are
subsequently
conjugated
with
sugars.
Demethylation
of
the
triazine
amine
results
in
the
formation
of
the
corresponding
hydroxy
triazine,
which
is
further
hydrolyzed
at
the
amino
group
to
form
the
dihydroxy
triazine.
2.
Analytical
method.
Adequate
analytical
methods
exist
for
the
detection
and
measurement
of
residue
levels
of
prosulfuron
in
or
on
raw
and
processed
commodities
of
cereal
grains,
and
for
meat,
milk
and
eggs.
The
limit
of
quantitation
(
LOQ)
is
0.01
ppm
for
crop
commodities,
processed
fractions
and
milk,
and
0.05
ppm
for
meat
and
eggs.
The
method
is
based
on
commodity­
specific
cleanup
procedures
followed
by
determination
by
high
performance
liquid
chromatography
with
ultraviolet
(
UV)
detection.
3.
Magnitude
of
residues.
Complete,
full
geography
residue
programs,
including
processing,
have
been
conducted
on
corn,
wheat
and
grain
sorghum.
A
three­
level
dairy
animal
feeding
study
to
determine
the
transfer
of
residues
of
prosulfuron
from
animal
feed
commodities
to
meat
and
milk
has
also
been
conducted.

B.
Toxicological
Profile
1.
Acute
toxicity.
EPA
has
set
an
acute
reference
dose
of
0.1
milligram/
kilogram/
day
(
mg/
kg/
day)
based
upon
a
no
observed
adverse
effect
level
(
NOAEL)
of
10
mg/
kg/
day
from
the
rat
acute
neurotoxicity
study
(
lowest
observed
adverse
effect
level
(
LOAEL)
of
250
mg/
kg/
day
due
to
reduced
motor
activity
and
body
temperature
in
males
and
impaired
righting
reflex
in
females)
and
a
100
 
fold
uncertainty
factor
(
UF).
2.
Genotoxicty.
Prosulfuron
was
negative
for
mutagenic/
genotoxic
effects
when
tested
in
a
bacterial
reverse
gene
mutation
assay
with
and
without
metabolic
activation
using
different
S.
typhimurium
and
E.
coli
stains;
in
a
mammalian
gene
mutation
study
using
V79
cells;
in
an
in
vitro
mammalian
cytogenetic
test
using
Chinese
hamster
ovary
(
CHO)
cells
with
and
without
metabolic
activation;
in
a
micronucleus
test
in
mice;
and
in
a
DNA­
repair
using
freshly
isolated
rat
liver
hepatocytes.
3.
Reproductive
and
developmental
toxicity.
The
data
base
on
prosulfuron
relative
to
prenatal
and
postnatal
effects
for
children
is
considered
to
be
essentially
complete
with
no
data
gaps.
The
developmental
and
reproductive
toxicity
data
do
not
indicate
increase
susceptibility
of
rats
or
rabbits
to
in
utero
and/
or
postnatal

prosulfuron.
In
a
rat
teratology
study,
evidence
of
maternal
toxicity
(
decreased
body
weight
gain
and
reduced
food
consumption)
and
developmental
toxicity
(
increased
incidence
of
skeletal
variations
that
was
not
significantly
different
from
the
historical
control)
was
found
at
the
maximum
tolerated
dose
of
400
mg/
kg.
There
was
no
evidence
of
teratogenicity
at
any
dose,
and
the
maternal
and
developmental
NOAELs
were
established
at
200
mg/
kg.
In
a
rabbit
teratology
study,
maternal
toxicity
(
decreased
body
weight
gain
and
reduced
food
consumption)
was
observed
in
the
100
mg/
kg
dose
group.
There
was
no
evidence
of
teratogenicity
at
any
dose.
Since
a
range­
finding
rabbit
teratology
study
had
seen
additional
clinical
findings
and
fetotoxicity
at
maternally
toxic
doses
( 
150
mg/
kg)
but
not
in
the
definitive
study
at
up
to
100
mg/
kg,
a
second
rabbit
teratology
study
was
conducted
at
doses
of
0,
20,
100,
and
200
mg/
kg/
day.
Maternal
toxicity
was
observed
at
200
mg/
kg.
The
developmental
NOAEL
was
100
mg/
kg
and
the
maternal
NOAEL
was
20
mg/
kg
in
this
study.
There
was
no
evidence
of
teratogenicity
at
any
dose.
A
rat
multigenerational
reproduction
study
indicated
reproductive
and
systemic
NOAELs
of
13.3
mg/
kg/
day
based
on
decreased
mean
body
weights
and
body
weight
gain
observed
at
136
mg/
kg/
day
for
both
pups
and
parental
animals.
No
treatment­
related
effects
on
reproductive
performance
(
i.
e.,

produce,
deliver
or
raise
litters),
litter
sizes,
viability
of
pups,
and
necropsy
findings
in
parental
animals
and
offspring
were
noted
up
to
the
highest
dose
level.
4.
Subchronic
toxicity.
The
liver
was
identified
as
a
target
organ
at
high
doses
in
the
rat,
mouse,
and
dog
as
indicated
by
slightly
increased
liver
enzymes
and
liver
weights.
No
histomorphologic
correlates
of
liver
damage
was
noted
in
the
90
 
day
studies
except
in
the
mouse
study
where
centrilobular
hypertrophy
was
found
in
males
at
feeding
levels
 
1,750
ppm
and
in
females
at
levels
 
3,500
ppm.
In
general,
NOAELs
for
target
organ
effects
were
established
at
doses
that
were
much
higher
than
overall
study
NOAELs,
which
were
based
on
other
indicators
of
toxicity
such
body
weight
gain.
5.
Chronic
toxicity.
In
the
1
 
year
dog
chronic
dosing
study,
the
NOAEL
was
1.84
mg/
kg/
day
based
on
hematologic
and
clinical
chemistry
effects
and
incidence
of
lipofuscin
accumulation
in
the
liver
at
18.6
mg/
kg/
day.
In
the
18
 
month
mouse
carcinogenicity
study,
there
was
no
evidence
of
carcinogenic
effects
up
to
the
highest
dose
tested
(
HDT)
of
1,062
mg/
kg/
day.
The
NOAEL
was
1.71
mg/
kg/
day
in
males,
and
100
mg/
kg/
day
in
females
based
on
increased
incidence/
severity
of
centrilobular
hepatocellular
hypertrophy.
A
2
 
year
chronic
feeding/
carcinogenicity
study
in
rats
indicated
systemic
NOAEL
of
7.9
mg/
kg/
day
was
based
on
decreased
body
weight
and
body
weight
gain,
hematopoietic
effects
(
males),
and
possibly
increased
serum
GGT
and
decreased
liver,
kidney,
and
adrenal
weights
(
females)
at
79.9
mg/
kg/
day.
There
was
uncertain
evidence
of
carcinogenicity
with
slight
increases
in
the
incidence
of
mammary
gland
adenocarcinomas
in
females
at
95.7
and
205.8
mg/
kg/
day,
slight
increase
in
incidence
of
benign
testicular
interstitial
cell
tumors
at
79.9
and
160.9
mg/
kg/
day
(
significant
trend
only).
Considering
the
weight
of
the
evidence,
the
EPA
Reference
Dose
Committee
previously
concluded
that
the
chemical
should
be
classified
as
a
Group
D
carcinogen
(
inadequate
evidence),
not
classifiable
as
to
human
carcinogenicity.
The
HIARC
(
meeting
December
2,
1999)
accepted
the
previous
conclusions
and
updated
the
cancer
classification
to
the
new
classification:
``
data
are
inadeqate,''
with
no
new
studies
required.
EPA
has
set
a
chronic
reference
dose
of
0.02
mg/
kg
based
on
a
NOAEL
of
1.84
mg/
kg
in
a
dog
feeding
study
and
a
100
 
fold
UF.
6.
Animal
metabolism.
The
metabolic
pathways
in
the
rat,
goat,
and
hen
are
similar
and
are
adequately
understood.
Prosulfuron
is
rapidly
absorbed
from
the
gastrointestinal
(
GI)
tract
of
rats
and
is
rapidly
excreted.
Approximately
90%
of
the
administered
dose
is
excreted
during
the
first
48
hours,
predominately
via
urine.
Tissue
residues
are
low.
Prosulfuron
is
metabolized
primarily
via
hydroxylation
at
side
chain
and
phenyl
ring
positions
and
O­
demethylation
of
the
triazyl
methoxy
group.
Minor
pathways
include
unsaturation
of
the
trifluoropropyl
side
chain,
hydrolysis
of
the
phenylsulfonylurea
bridge
and
oxidative/
hydrolytic
cleavage
of
the
triazine
ring
system.
In
the
goat,
the
orally
administered
prosulfuron
is
quickly
eliminated
primarily
via
the
urine
as
prosulfuron.
The
metabolism
of
prosulfuron
in
the
goat
follows
a
similar
pathway
as
observed
in
the
rat
although
not
as
extensive.
The
majority
of
the
residues
were
accounted
for
as
prosulfuron,
the
triazine
amine,
which
results
from
bridge
hydrolysis
(
CGA
 
150829)
and
the
triazinyl
hydroxymethyl
metabolite
(
CGA
 
273437).
In
the
hen,
metabolism
is
similar
to
that
observed
in
the
rat
and
goat.
The
major
residues
found
in
edible
tissues
and
eggs
were
prosulfuron,
the
triazine
amine
(
CGA
 
150829),
and
the
sulfonamide
(
CGA
 
159902)
which
results
from
hydrolysis
of
the
sulfonylurea
bridge.
7.
Metabolite
toxicology.
Metabolic
pathways
of
prosulfuron
in
plants
and
animals
are
comparable
and
no
detectable
residues
are
found
in
or
on
crops.
All
relevant
plant
metabolites
are
observed
in
the
animals
and
are
thus
toxicologically
covered.
The
remaining
plant
metabolites
are
toxicologically
insignificant.
Therefore,
parent
prosulfuron
is
the
appropriate
compound
for
the
tolerance
expression
and
analytical
monitoring.
8.
Endocrine
disruption.
Prosulfuron
does
not
belong
to
a
class
of
chemicals
known
for
having
significant
adverse
effects
on
the
endocrine
system.
Developmental
toxicity
studies
in
rats
and
rabbits
and
reproduction
study
in
rats
gave
no
indication
that
prosulfuron
might
have
any
effects
on
endocrine
function
related
to
development
and
reproduction.
The
subchronic
and
chronic
studies
also
showed
no
evidence
of
a
long­
term
effect
related
to
the
endocrine
system.

C.
Aggregate
Exposure
1.
Dietary
exposure.
Acute
and
chronic
dietary
exposure
assessments
were
conducted
for
prosulfuron
using
tolerance
values
published
in
40
CFR
180.481.
In
both
assessments
it
was
assumed
that
100%
of
all
corn
and
cereal
grains
were
treated
with
prosulfuron
(
100%
market
share).
The
exposure
analyses
was
conducted
using
food
consumption
data
from
USDA's
1994
 
1996

i.
Food.
Chronic
exposure
was
compared
to
a
RfD
of
0.02
mg/
kg
based
on
a
NOAEL
of
1.84
mg/
kg
in
a
dog
feeding
study
and
a
100
 
fold
UF.
This
exposure
analysis
showed
that
the
U.
S.
population
had
an
exposure
of
less
than
1%
of
the
chronic
RfD.
The
most
sensitive
subpopulation
was
children
(
1
 
6
years
old)
with
a
chronic
exposure
of
2.4%.
Acute
exposure
was
compared
to
an
acute
RfD
of
0.1
mg/
kg,
which
was
based
on
a
NOAEL
of
10
mg/
kg
from
an
acute
neurotoxicity
study
in
the
rat
and
a
100
 
fold
UF.
The
most
sensitive
subpopulation
was
all
infants
with
an
exposure
of
2.2%
of
the
acute
RfD.
The
U.
S.
population
showed
an
exposure
of
1.5%
of
the
RfD.
These

estimate,
1.86
parts
per
billion
(
ppb),
was
used
in
the
acute
exposure
analysis
and
the
corrected
56
 
day
drinking
water
concentration
of
0.4667
ppb
was
used
in
the
chronic
exposure
analysis.
The
SCIGROW
estimated
ground
water
concentration
for
the
prosulfuron
uses
of
0.406585
ppb
contributed
little
to
the
overall
exposure.
The
acute
drinking
water
levels
of
concern
(
DWLOC)
for
prosulfuron
were
based
on
the
acute
RfD,
a
margin
of
exposure
(
MOE),
the
99.9th
percentile
of
the
acute
dietary
exposure
for
U.
S.
population
subgroups
and
the
body
weight
­
daily
water
consumption
of
each
respective
subgroup.
The
calculated
acute
DWLOC
values
for
the
population
subgroups
ranged
from
978
 
3447
ppb.
The
estimated
ground
water
concentration
(
0.406585
ppb)
and
the
peak
day
 
0
surface
water
concentration
(
1.86
ppb)
of
prosulfuron
did
not
exceed
the
acute
DWLOC
values.
The
chronic
(
noncancer
DWLOC
for
prosulfuron
were
based
on
the
chronic
RfD,
any
estimated
residential
exposure,
the
chronic
dietary
exposure
for
select
U.
S.
population
subgroups
and
the
body
weight
­
daily
water
consumption
of
each
respective
subgroup.
The
calculated
chronic
DWLOC
values
for
the
population
subgroups
ranged
from
197
 
694.
The
estimated
ground
water
concentration
(
0.406585
ppb)
and
the
corrected
average
56
 
day
surface
water
concentration
(
0.4667
ppb)
of
prosulfuron
did
not
exceed
the
chronic
DWLOC
values.
Therefore,
there
is
reasonable
certainty
that
the
residues
of
prosulfuron
in
the
drinking
water
would
not
result
in
unacceptable
levels
of
acute
or
chronic
aggregate
human
health
risk,
and
that
such
exposure
would
not
exceed
the
exposure
allowable
by
the
risk
cup.
Nondietary
exposure.
Nondietary
exposure
to
prosulfuron
is
considered
negligible
as
the
chemical
is
registered
for
agricultural
use
only.
For
workers
handling
this
chemical,
acceptable
MOE
(
in
the
range
of
thousands)
have
been
obtained
for
both
acute
and
chronic
scenarios.

D.
Cumulative
Effects
Consideration
of
a
common
mechanism
of
toxicity
is
not
appropriate
at
this
time
since
there
is
no
information
to
indicate
that
toxic
effects
produced
by
prosulfuron
would
be
cumulative
with
those
of
any
other
types
of
chemicals.

E.
Safety
Determination
1.
U.
S.
population.
The
calculation
shows
that
less
than
1%
of
the
RfD
will
be
utilized
for
the
U.
S.
population
based
on
chronic
toxicity
endpoints.
EPA
generally
has
no
concern
for
exposures
below
100%
of
the
RfD
because
the
RfD
represents
the
level
at
or
below
which
daily
aggregate
dietary
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
It
is
concluded
that
there
is
a
reasonable
certainty
that
no
harm
will
result
from
aggregate
exposure
to
prosulfuron
residue.
2.
Infants
and
children.
The
calculated
percent
of
the
RfD
that
will
be
utilized
by
aggregate
exposure
to
residues
of
prosulfuron
is
only
2.4%
for
children
(
1
to
6
years
old),
the
most
impacted
subpopulation.
There
were
no
adverse
reproductive
or
developmental
effects
indicated
in
the
prosulfuron
toxicity
data
base,
which
is
considered
to
be
essentially
complete
with
no
data
gaps.
It
is
concluded
that
there
is
a
reasonable
certainty
that
no
harm
will
result
to
infants
and
children
from
aggregate
exposure
to
prosulfuron
residues.

F.
International
Tolerances
