Under
FIFRA,
as
amended
in
1988,
EPA
is
conducting
an
accelerated
reregistration
program
to
reevaluate
existing
pesticides
to
make
sure
they
meet
current
scientific
and
regulatory
standards.
The
data
base
to
support
the
reregistration
of
diazinon
is
substantially
complete.
Taking
into
account
both
the
risks
and
benefits
of
diazinon
uses,
the
Agency
has
determined
that
with
the
adoption
of
all
the
mitigation
measures
recommended
in
the
IRED,
use
of
diazinon
will
not
pose
unreasonable
adverse
risks
to
people
or
the
environment
when
used
according
to
its
currently
approved
labeling.
Please
note
that
this
is
only
an
interim
decision.
Upon
the
Agency's
completion
of
its
assessment
of
the
cumulative
risk
posed
by
the
organophosphates
as
a
class,
EPA
will
issue
a
final
reregistration
eligibility
decision
on
pesticides
containing
diaizinon.
All
registrants
of
pesticide
products
containing
diazinon
will
be
sent
the
appropriate
REDs,
labeling
requirements
and
product
specific
data
requirements
pending
OMB
approval
of
the
diazinon
Data
Call­
In.
The
reregistration
program
is
being
conducted
under
Congressionally
mandated
time
frames,
and
EPA
recognizes
both
the
need
to
make
timely
reregistration
decisions
and
to
involve
the
public.
Therefore,
EPA
is
issuing
this
IRED
with
a
60­
day
comment
period.
The
comment
period
is
intended
to
provide
an
opportunity
for
public
input
and
a
mechanism
for
initiating
any
necessary
amendment
to
the
IRED.
EPA
invites
comment
specifically
on
the
use
of
the
diazinon
benefit
assessments
which
can
be
found
with
the
diazinon
documents
on
the
EPA's
website
at
http://

gov/
pesticides/
reregistration/
status.
htm.
All
comments
will
be
carefully
considered
by
the
Agency.
If
any
comment
significantly
affects
this
IRED,
EPA
will
amend
the
IRED
by
publishing
the
amendment
in
the
Federal
Register.

B.
What
is
the
Agency's
Authority
for
Taking
this
Action?

The
legal
authority
for
this
IRED
falls
under
FIFRA,
as
amended
in
1988
and
1996.
Section
4(
g)(

A)
of
FIFRA
directs
that,
after
submission
of
all
data
concerning
a
pesticide
active
ingredient,
``
the
Administrator
shall
determine
whether
pesticides
containing
such
active
ingredient
are
eligible
for
reregistration,
''
before
calling
in
product
specific
data
on
individual
end­
use
products,
and

product,
when
exposed
to
air,
decomposes
and
releases
gaseous
ammonia.
Ammonia
is
a

The
ammonia
released
from
the

2.
Magnitude
of
residue
at
the
time
of
harvest
and
method
used
to
determine
the
residue.
The
end
use
product
contains
4
grams
of
ammonium
bicarbonate
bound
in
a
polymer.
The
polymer
is
attached
to
a
cellulose
card
material
which
is
approximately
19
centimeters
(cm)
by
20
cm
in
size.
The
card
is
suspended
from
olive
tree
limbs
at
a
rate
of
42
cards
per
acre
of
olive
orchard
resulting
in
168
grams
(0.37
pounds)
of
ammonium
bicarbonate
per
acre
of
orchard.
Being
contained
in
the
polymer
and
attached
to
the
cellulose
card
there
is
little
opportunity
for
the
ammonium
bicarbonate
to
come
in
contact
with
either
the
fruit
or
the
soil.
Upon
application
the
end
use
product
will
be
constantly
exposed
to
sunlight
and
elevated
temperatures
which
will
continually
release
very
small
amounts
of
gaseous
ammonia.
Ammonia
is
a
naturally
occurring
compound
which
is
a
key
intermediate
in
the
nitrogen
cycle.
Under
normal
conditions,
ammonia
is
essential
for
many
biological
processes.
Ammonia
may
be
released
to
the
atmosphere
by
volatilization
from
numerous
sources
including:
Decaying
organic
matter,
animal
livestock
excreta,
fertilization
of
soil,
and
burning
of
coal,
wood,
and
other
natural
products.
Because
of
its
significance
in
natural
cycles,
ammonia
is
found
at
a
local
concentration
in
most
environmental
media.
The
half­
life
of
atmospheric
ammonia
is
estimated
to
be
only
a
few
days.
In
olive
orchards
atmospheric
concentrations
of
ammonia
will
be
present
from
the
decay
of
organic
matter
and
from
the
application
of
fertilizer
to
soil
as
ammonia,
ammonium
compounds
or
ammonia
precursors
(such
as
urea).
Because
ammonia,
as
ammonium
ion,
is
the
nutrient
of
choice
for
many
plants,
uptake
of
soil
ammonia
by
living
plants
is
an
important
fate
process.
The
rate
of
uptake
by
plants
varies
with
the
growing
season.
At
normal
environmental
concentrations,
ammonia
does
not
have
a
very
long
soil
half­
life.
It
is
either
rapidly
taken
up
by
plants,
bioconverted
by
the
microbial
population,
or
volatilized
to
the
atmosphere.
Under
the
conditions
of
use
proposed
and
given
the
natural
background
levels
of
ammonia
in
the
atmosphere
and
in
the
soil,
no
residues
of
ammonia
or
of
ammonium
bicarbonate
are
expected
to
occur
in
olive
fruit
from
the
use
of
the
olive
fly
attract
and
kill
(A&
K)
target
device.
3.
Residues
in
olive
fruit
are
not
expected
from
the
use
of
the
olive
fly
attract
and
kill
target
device;
therefore,
an
analytical
method
is
not
needed.

C.
Mammalian
Toxicological
Profile
Because
toxicity
studies
in
the
scientific
literature
are
limited
for
ammonium
bicarbonate,
data
on
the
related
ammonium
salt,
ammonium
chloride,
and
on
the
carbonate
salt,
sodium
bicarbonate,
are
discussed.
The
single
dose
LD50
of
ammonium
chloride
in
the
mouse
and
the
rat,
administered
orally,
is
reported
in
scientific
literature
as
1,300
milligrams/
kilogram
(mg/
kg)
and
1,650
mg/
kg,
respectively.
The
single
dose
LD50
of
sodium
bicarbonate
in
the
mouse
and
rat,
administered
orally,
is
reported
in
scientific
literature
as
5,650
mg/
kg
and
3,400
mg/
kg,
respectively.
For
ammonia,
the
acute
inhalation
LC50
in
the
rat
exposed
for
a
single
period
of
15
minutes,
was
reported
in
scientific
literature
as
17,401
parts
per
million
(ppm).
The
acute
inhalation
LC50
in
the
mouse
exposed
for
a
single
period
of
30
minutes
was
reported
as
21,430
ppm.
D.
Aggregate
Exposure
1.
Dietary
exposureÑ
i.
Food.
Ammonium
bicarbonate
as
used
in
the
olive
fly
attract
and
kill
target
device
will
not
come
into
direct
contact
with
olives.
Therefore,
no
residues
of
this
compound
are
expected
to
occur
in
olives.
Ammonium
bicarbonate
is
listed
by
the
U.
S.
Food
and
Drug
Administration
as
a
direct
food
additive
and
is
commonly
used
as
a
leavening
agent
in
baked
goods.
There
is
some
potential
for
the
decomposition
product
ammonia
gas
to
come
into
contact
with
growing
olives.
However,
it
is
expected
that
levels
of
gaseous
ammonia
would
be
well
below
the
normal
background
levels
of
atmospheric
ammonia
present
in
an
area
of
crop
production.
ii.
Drinking
water.
Given
the
mode
of
application
whereby
the
ammonium
bicarbonate
is
bound
in
a
polymer
matrix
attached
to
a
cellulose
card
which
is
suspended
from
olive
tree
branches,
there
is
little
likelihood
that
residues
of
ammonium
bicarbonate
would
occur
in
drinking
water
from
this
use.
2.
Non­
dietary
exposure.
When
exposed
to
air,
sun
and
elevated
temperatures
in
an
olive
orchard,
the
ammonium
bicarbonate
will
slowly
decompose
to
ammonia,
carbon
dioxide,
and
water
vapor.
The
total
amount
of
ammonium
bicarbonate
applied
per
acre
in
the
olive
fly
attract
and
kill
target
devices
is
168
grams.
Assuming
the
complete
consumption
of
the
ammonium
bicarbonate
during
the
growing
season,
the
theoretical
yield
of
ammonia
would
be
equal
to
approximately
36.1
grams.
Assuming
that
this
amount
of
ammonia
is
distributed
over
an
acre
of
olive
orchard
to
a
height
of
15
feet
at
a
single
point
in
time,
this
is
equal
to
a
theoretical
concentration
of
3
parts
per
billion
(ppb)
of
ammonia.
But
a
more
realistic
scenario
would
take
into
account
that
the
release
of
ammonia
would
occur
over
the
4Ð
5
month
period
after
application
in
the
orchard
resulting
in
a
daily
concentration
that
is
approximately
one
hundred
times
less,
i.
e.
0.025
ppb.
This
concentration
of
ammonia
would
be
well
below
the
worldwide
atmospheric
background
concentration
of
ammonia
that
has
been
estimated
in
scientific
literature
at
approximately
1Ð
3
ppb.
Also
by
comparison,
farmers
can
be
exposed
to
ammonia
when
applying
fertilizer.
The
ammonia
concentration
over
a
field
during
the
application
of
gaseous
anhydrous
ammonia
fertilizer
was
reported
in
scientific
literature
as
high
as
213
microgram/
cubic
meter
(ug/
m
3
)

ppb.
This
is
ten
thousand
fold
higher
than
the
theoretical
exposure
from
the
olive
fly
attract
and
kill
target
device.

E.
Cumulative
Exposure
Because
of
the
method
of
application
and
the
low
use
rates
of
ammonium
bicarbonate,
little
to
no
exposure
is
expected.
Since
ammonium
bicarbonate
is
approved
as
a
direct
food
additive
and
is
listed
as
``
Generally
Recognized
as
Safe''
by
the
U.
S.
Food
and
Drug
Administration,
there
is
no
concern
regarding
the
potential
for
cumulative
effects
of
ammonium
bicarbonate
from
the
proposed
use
with
other
substances
due
to
a
common
mechanism
of
action.

F.
Safety
Determination
1.
U.
S.
population.
Evidence
of
ammonium
bicarbonate's
low
toxicity
is
demonstrated
in
the
data
reported
for
the
related
salts,
ammonium
chloride
and
sodium
bicarbonate.
The
U.
S.
Food
and
Drug
Administration
has
placed
the
following
limitations
on
the
maximum
allowable
levels
of
ammonium
bicarbonate
in
processed
foods:
up
to
3.2%
in
baked
goods,
grain,
snack
foods
and
reconstituted
vegetables.
This
is
the
equivalent
of
32,000
ppm
of
ammonium
bicarbonate
concentration
in
these
foods.
Ammonium
bicarbonate
is
exempt
from
the
requirement
of
a
tolerance
under
40
CFR
180.1001(
c)
when
it
is
used
as
a
surfactant,
suspending
agent
or
dispensing
agent
in
pesticide
formulations
applied
to
growing
crops
or
to
raw
agricultural
commodities
after
harvest.
The
amount
of
ammonium
bicarbonate
used
in
a
pesticide
formulation
is
not
restricted
by
40
CFR
180.1001(
c).
Therefore,
any
level
of
residue
of
ammonium
bicarbonate
in
or
on
olives
is
currently
acceptable
when
used
for
these
purposes.
Given
the
method
of
application
of
ammonium
bicarbonate
where
it
is
bound
in
a
polymer
within
a
discrete
target
device
it
is
extremely
unlikely
for
this
compound
to
come
into
contact
with
and
result
in
residues
in
or
on
olive
fruit.
Thus,
aggregate
exposure
to
ammonium
bicarbonate
from
use
in
the
olive
fly
attract
and
kill
target
device
and
any
risk
to
human
health
will
be
negligible.
2.
Infants
and
children.
Given
the
low
toxicity
of
the
related
salts
ammonium
chloride
and
sodium
bicarbonate
and
the
allowable
levels
of
ammonium
bicarbonate
in
processed
foods,
there
is
a
reasonable
certainty
of
no
harm
to
children
and
infants
from
the
use
of
the
olive
fly
attract
and
kill
target
device
in
olive
orchards.
G.
Effects
on
the
Immune
and
Endocrine
Systems
Certis
USA
has
no
information
to
suggest
that
ammonium
bicarbonate
will
adversely
affect
the
immune
or
endocrine
systems.

H.
Existing
Tolerances
Ammonium
bicarbonate
is
exempt
from
the
requirement
of
a
tolerance
under
40
CFR
180.1001(
c)
when
used
as
an
inert
ingredient
in
pesticide
formulations
applied
to
growing
crops
or
to
raw
agricultural
commodities
after
harvest.
Ammonia
is
exempt
from
the
requirement
of
a
tolerance
under
40
CFR
180.1003
when
used
as
a
fungicide
applied
to
grapefruit,
lemons,
oranges,
and
corn
grain.

I.
International
Tolerances
There
is
no
Codex
maximum
residue
level
(MRL)
for
ammonium
bicarbonate.
Canada
has
established
permitted
residue
levels
of
ammonium
bicarbonate
in
cocoa
products
and
in
unstandardized
food
products.
