less
than
12.5%
of
the
cPAD
for
the
total
U.
S.
population
and
all
the
subpopulations.
The
greatest
exposure
occurred
in
infants
and
children.
Exposure
estimates
for
the
acute
dietary
assessment
were
well
under
100%
of
the
acute
population
adjusted
dose
(
aPAD)
at
the
99th
percentile.
The
overall
U.
S.
population
and
the
highest
exposed
subpopulation
(
infants
<
1
year)
utilized
only
5.3%
and
less
than
21%,
respectively.
ii.
Drinking
water.
There
are
no
established
maximum
contaminant
levels
or
health
advisory
levels
for
residues
of
BAS
670
H
or
its
metabolites
in
drinking
water.
A
tier

modeling
assessment
for
BAS
670
H
using
the
FIRST
model
(
for
surface

and
SCI­

(
for
ground
water)
produced
estimated
maximum
concentrations
of
0.22
parts
per

(
ppb)
(
chronic)
for
surface
water
and
0.20
ppb
for
ground
water.
These
estimated
concentrations
are
less
than
a
worst
case
calculated
acceptable
level
of
3.95
ppb
children
chronic
drinking
water
levels
of
concern
(
DWLOC)
for
residues
in
drinking
water
based
on
chronic
aggregate
exposure.
Therefore,
taking
into
account
all
uses
and
exposures
one
concludes,
with
reasonable
certainty
that
residues
of
BAS
670
H
in
drinking
water
will
not
result
in
unacceptable
levels
of
aggregate
human
health
risk
at
this
time.

Non­
dietary
exposure.
There
are
no
registered
or
proposed
residential
uses
for
BAS
670
H.

D.
Cumulative
Effects
At
this
time,
there
is
no
available
information
to
indicate
that
BAS
670
H
or
its
metabolites
have
a
common
mechanism
of
toxicity
with
other
substances.
Therefore,
there
is
no
reason
to
include
this
pesticide
or
its
metabolites
in
a
cumulative
risk
assessment.
For
the
purposes
of
this
tolerance
action,
EPA
has
not
assumed
that
BAS
670
H
and
its
metabolites
have
a
common
mechanism
of
toxicity
with
other
substances.

E.
Safety
Determination
1.
U.
S.
population.
Aggregate
exposure
to
the
overall
U.
S.
population
utilized
only
8.7%
of
the
aPAD
and
12.7%
of
the
cPAD,
respectively.
Therefore,
no
harm
to
the
overall
U.
S.
population
would
result
from
the
use
of
BAS
670
H
on
field,
sweet,
or
pop
corn.
2.
Infants
and
children.
There
is
a
complete
toxicity
base
for
BAS
670
H
and
exposure
data
are
complete
or
are
estimated
based
on
data
that
reasonably
accounts
for
potential
exposures.
Taking
into
account
the
completeness
of
the
data
base,
BASF
Corporation
concludes
that
the
FQPA
safety
factor
should
be
retained
but
reduced
to
3X.
This
is
based
on
the
occurrence
of
kidney
malformations
in
rabbits
and
skeletal
variations
in
rabbits
and
rats,
all
occurring
at
doses,
which
caused
either
maternal
tyrosine
elevations
or
other
evidence
of
maternal
toxicity.
The
full
toxicological
data
base
that
has
been
developed
for
BAS
670
H
includes
many
additional
mechanistic
studies,
revealing
consistency
and
the
mode
of
action
of
these
effects.
The
kidney
was
a
target
organ
in
all
repeated
dose
studies
and
these
effects
were
caused
by
elevated
tyrosine
levels
due
to
inhibition
of
the
HPPD
enzyme.
Using
the
standard
worst
case
exposure
assumptions
(
residues
at
tolerance
level
and
100%
crop
treated),
aggregate
exposure
to
BAS
670
H
from
food
and
water
will
utilize
33%
and
less
than
24%
of
the
aPAD
and
cPAD,
respectively
for
infants
and
children.
EPA
generally
has
no
concern
for
exposures
below
100%
of
the
PAD
because
it
represents
the
level
at
or
below
which
daily
aggregate
exposure
over
a
lifetime
will
not
pose
appreciable
risks
to
human
health.
BASF
Corporation
concludes
that
there
is
a
reasonable
certainty
that
no
harm
will
result
to
infants
or
children
from
aggregate
exposure
to
BAS
670
H
residues
with
the
approval
of
this
tolerance
petition.

F.
International
Tolerances
No
maximum
residue
levels

have
been
established
for
BAS
670
H
by
the
CODEX

Commission
or

EPA
has
received
a
pesticide
petition
(
3F6516)
from
Eastman
Chemical
Company,
P.
O.
Box
511,
Kingsport,
TN
37662
proposing,
pursuant
to
section
408(
d)
of
the
FFDCA,
21
U.
S.
C.
346a(
d),
to
amend
40
CFR
part
180
to
establish
an
exemption
from
the
requirement
of
a
tolerance
for
the
biochemical
pesticide
acetic
acid.
Pursuant
to
section
408(
d)(
2)(
A)(
i)
of
the
FFDCA
as
amended,
Eastman
Chemical
Company
has
submitted
the
following
summary
of
information,
data,
and
arguments
in
support
of
their
pesticide
petition.
The
summary
of
the
petition
was
prepared
by
the
petitioner
and
represent
the
view
of
the
petitioner.
The
petition
summary
announces
the
availability
of
a
description
of
the
analytical
methods
available
to
EPA
for
the
detection
and
measurement
of
the
pesticide
chemical
residues
or
an
explanation
of
why
no
such
method
is
needed.
It
is
the
purpose
of
this
petition
to
reestablish
an
exemption
from
the
requirement
of
a
tolerance
for
acetic
acid
when
used
as
a
grain
and
hay
preservative
on
agricultural
commodities
such
as
alfalfa,
barley
grain,
Bermuda
grass,
bluegrass,
brome
grass,
clover,
corn
grain,
cowpea
hay,
fescue,
lespedeza,
lupines,
oat
grain,
orchard
grass,
peanut
grass,
Timothy,
vetch,
and
wheat
grain,
or
commodities
described
as
grain
or
hay.
Acetic
acid
is
currently
exempt
from
the
requirement
of
a
tolerance
when
used
as
a
catalyst
under
40
CFR
180.1001(
c).
Previously,
acetic
acid
was
exempt
from
the
requirement
of
a
tolerance
(
40
CFR
180.1029),
when
used
as
a
preservative
on
the
abovementioned
commodities.
This
exemption
was
canceled,
but
only
because
the
registrants
at
that
time,
did
not
wish
to
maintain
the
registration.
Subsequent
to
the
cancellation
of
the
registrations,
the
tolerance
exemption
was
revoked.

A.
Residue
Chemistry
There
have
been
no
analytical
procedures
conducted
to
ascertain
residual
acetic
acid
on
treated
commodities.
The
application
rate
for
the
preservation
of
grain
and
hay
as
per
instructions,
will
result
in
concentrations
of
about
1%
on
hay
and
about
1.5%
on
grain.
Additionally,
acetic
acid
is
generally
recognized
as
safe
(
GRAS)
under
the
Food
and
Drug
Administration
(
FDA),
40
CFR
184.1005,
for
use
in
food
when
used
in
accordance
with
good
manufacturing
or
feeding
practice.
Since
this
request
is
for
an
exemption
from
the
requirement
of
a
tolerance,
residual
acetic
acid
on
hay
and
grain
will
not
pose
a
problem
of
exposure
to
humans
or
the
environment
especially
since
acetic
acid
is
in
the
food
chain
and
is
naturally
occurring
in
nature.
Residuals
at
this
low
level
are
less
than
is
found
in
vinegar
used
on
foods.

B.

2.
Genotoxicity.
Acetic
acid
and
the
sodium
salt
of
acetic
acid,
provided
negative
results
for
mutagenicity
assays
in
strains
of
Salmonella
typhimurium.
3.
Reproductive
and
developmental
toxicity.
In
a
teratogenicity
study
by
the
Food
and
Drug
Research
Laboratories,
5%
acetic
acid
(
apple
cider
vinegar),
the
administration
of
up
to
1,600
mg/
kg
bwt,
to
pregnant
mice
for
10
consecutive
days
had
no
clear
discernible
effect
on
nidation
or
on
maternal
or
fetal
survival.
Additionally,
similar
acids
to
acetic
acid,
such
as
fumaric
acid
and
citric
acid,
illicit
no
teratogenic
or
reproductive
toxicity
in
rats
or
chick
embryos.
This
is
also
true
for
propionic
acid
(
or
salts
thereof)
which
is
used
in
the
same
manner
as
proposed
for
acetic
acid.

4.
Subchronic
toxicity.
Waivers
have
been
requested
for
the
90
 
day
feeding,
dermal
and
inhalation
studies.
The
conditions
of
potential
exposure
requiring
these
studies
are
not
triggered.
Acetic
acid
is
a
food
acid
and
is
naturally
occurring.
Acetic
acid
is
absorbed
from
the
gastrointestinal
tract
and
through
the
lungs
and
is
readily,
although
not
completely,
oxidized
in
the
organism.
Acetic
acid
is
proposed
to
be
used
as
a
hay
and
grain
preservative
at
low
concentrations,
and
for
animal
food
only,
and
these
low
concentrations
are
lower
than
is
found
in
commercially
available
vinegar
(
5%
to
7%).
Therefore,
there
would
be
no
expected
subchronic
effects
from
the
limited
exposure
expected
to
acetic
acid,
and
the
waivers
should
be
granted.
5.
Chronic
toxicity.
Waivers
have
been
requested
for
chronic
toxicity
requirements
for
acetic
acid.
However,
the
results
of
two
Russian
studies
reported
the
induction
of
hyperplasia
in
rats
at
60
mg/
kg
bwt.
This
result
is
similar
to
induction
of
hyperplasia
in
rats
by
propionic
acid
in
a
2
 
year
study.
6.
Animal
metabolism.
Acetic
acid
is
a
food
acid
and
is
naturally
occurring.
Acetic
acid
is
utilized
as
an
energy
source
in
the
body
by
combining
first
with
Co­
enzyme
A
to
form
Acetyl­
CoA
which
then
enters
the
Kreb's
citric
acid
cycle
by
combining
with
oxaloacetate
to
yield
citrate.
This
process
is
active
in
all
animals
and
higher
plants
and
is
carried
out
in
the
mitochondria.
Acetic
acid
is
proposed
to
be
used
as
a
hay
and
grain
preservative
at
low
concentrations,
and
for
animal
food
only.
There
are
no
expected
adverse
effects.
7.
Metabolite
toxicity.
Acetic
acid
is
a
food
acid
and
is
naturally
occurring
in
the
environment
as
well
as
in
plants
and
animals.
Acetic
acid
is
utilized
as
an
energy
source
in
the
body
by
combining
first
with
Co­
enzyme
A
to
form
Acetyl­
CoA
which
then
enters
the
Kreb's
citric
acid
cycle
by
combining
with
oxaloacetate
to
yield
citrate.
This
process
is
active
in
all
animals
and
higher
plants
and
is
carried
out
in
the
mitochondria.

C.
Aggregate
Exposure
1.
Dietary
exposure.
Acetic
acid
is
a
food
acid
and
is
naturally
occurring
in
plants
and
animals.
Acetic
acid
is
utilized
as
an
energy
source
in
the
body
by
combining
first
with
Co­
enzyme
A
to
form
Acetyl­
CoA
which
then
enters
the
Kreb's
citric
acid
cycle
by
combining
with
oxaloacetate
to
yield
citrate.
This
process
is
active
in
all
animals
and
higher
plants
and
is
carried
out
in
the
mitochondria.
Acetic
acid
is
most
commonly
encountered
by
the
human
population
in
the
form
of
vinegar,
varying
in
concentration
of
acetic
acid,
from
4
 
7%.
Acetic
acid
is
considered
generally
recognized
as
safe
(
GRAS)
by
FDA
when
directly
added
to
foods
(
20
CFR
184.1005).
There
are
no
reports
in
the
literature
of
contact
sensitization
to
vinegar.
Used
in
accord
with
instructions
for
the
preservation
of
grain
and
hay,
the
concentration
of
acetic
acid
on
the
commodities
used
for
animal
food,
will
be
less
than
2%.
Dietary
exposure
to
acetic
acid
used
in
this
application
will
therefore
pose
no
threat
to
humans
or
the
environment.
2.
Non­
dietary
exposure.
The
only
non­
dietary
exposure
to
acetic
acid
is
the
occupational
exposure.
Acetic
acid
end­
use
products
are
sprayed
on
grains
and
hay
at
application
rates
in
ranges
of
less
than
3%
on
the
commodity,
depending
on
the
moisture
content
of
the
treated
crop.
Based
on
the
use
patterns,
the
potential
for
exposure
of
applicators
and
workers
in
the
field
being
treated
with
acetic
acid
could
be
significant.
However,
applicators
are
generally
confined
in
the
cab
of
the
tractor
pulling
the
collecting
systems
to
which
the
applicating
sprays
are
attached.
The
hay
or
grain
collected
would
contain
less
than
3%
of
the
acetic
acid
and
therefore
subsequent
exposure
to
the
crop
would
cause
no
significant
exposure
to
the
acetic
acid.
Certain
protective
clothing
is
recommended
for
acetic
acid
users
due
to
eye
and
skin
hazards
associated
with
the
handling
of
concentrated
acetic
acid
and
the
use
of
such
clothing
and
protective
equipment
is
presented
on
the
label.

D.
Cumulative
Effects
Acetic
acid
is
used
similarly
as
propionic
acid,
for
the
preservation
of
hay
and
grains.
Under
an
aerobic
conditions
propionic
acid
acts
as
a
carbon
source
for
various
microbes
and
is
metabolized
to
acetic
acid,
methane,
carbon
dioxide,
and
water.
For
propionic
acid,
the
metabolite
of
acetic
acid
poses
no
problems
because
acetic
acid
is
also
found
in
the
food
chain,
is
naturally
occurring,
and
is
applied
in
the
same
manner
as
propionic
acid
as
a
pesticide.
For
propionic
acid
all
environmental
fate
data
requirements
are
waived
for
the
uses
this
petition
requests
for
acetic
acid.
There
should
be
no
concern
for
cumulative
effects
for
acetic
acid
as
well.

E.
Safety
Determination
Human
health
assessment
 
i.
U.
S.
population.
Acetic
acid
is
a
normal
component
of
metabolism
in
the
human
body
and
humans
ordinarily
consume
acetic
acid
as
vinegar,
as
a
natural
component
of
common
foods,
and
as
an
added
ingredient.
Dietary
exposure
from
pesticidal
use
would
be
very
low.
ii.
Infants
and
children.
As
noted
above
acetic
acid
is
produced
by
the
human
body.
Humans
include
infants
and
children
as
well
as
adults.
For
the
same
reasons
as
above,
dietary
exposure
from
pesticidal
use
would
be
of
minimal
concern.

F.
Tolerance
Exemptions
for
the
Proposed
Uses
The
petitioner
proposes
that
the
use
of
acetic
acid
as
a
grain
and
hay
preservative
be
granted
an
exemption
from
the
requirement
of
a
tolerance,
as
proposed
below:
1.
Post­
harvest
application
of
acetic
acid,
when
used
as
a
fungicide
or
preservative
is
exempted
from
the
requirement
of
a
tolerance
for
residues
in
or
on
the
following
raw
agricultural
commodities:
Alfalfa,
barley
grain,
Bermuda
grass,
bluegrass,
brome
grass,
clover,
corn
grain,
cowpea
hay,
fescue,
lespedeza,
lupines,
oat
grain,
orchard
grass,
peanut
hay,
peavine
hay,
rye
grass,
sorghum
grain,
soybean
hay,
sudan
grass,
Timothy,
vetch,
and
wheat
grain,
or
commodities
described
as
grain
or
hay.
2.
Acetic
acid
is
exempt
from
the
requirement
of
a
tolerance
for
residues
in
or
on
meat,
and
meat
by­
products:
Cattle,
sheep,
hogs,
goats,
horses,
and
poultry,
milk,
and
eggs
when
applied
as
a
bactericide/
fungicide
to
livestock
drinking
water,
poultry
litter,
and
storage
areas
for
silage
and
grain.
3.
Post­
harvest
application
of
acetic
acid
when
used
as
a
fungicide/
preservative
is
exempted
from
the
requirement
of
a
tolerance
for
residues
in
or
on
the
following
raw
agricultural
commodities:
Cottonseed,
peanuts,
rice
grain,
and
soybeans.
Noticeably,
this
tolerance
exemption
request
re­
establishes
the
same
exemption
criteria
as
was
previously
granted
for
acetic
acid
for
this
use.

G.
International
Tolerances
There
are
no
known
international
tolerances
for
residues
of
acetic
acid
in
food
or
animal
feed.
