METHYL
BROMIDE
USE
This
sector
includes
rice
mills,
flour
mills,
pet
food
manufacturing
facilities,
and
a
few
bakeries.
Primarily
this

that
contain
electronic
components
and
have
machinery
with
copper
and
copper
alloy
parts.
These
facilities
are
under
intense
pressure
from
many
insect
pests.
The
flour
millers
and
the
bakeries
in
this
sector
do
not
target
any
of
their
commodities
to
be
fumigated
with
methyl

BRIEF
SUMMARY
OF
THE
NEED
FOR
METHYL
BROMIDE
AS
A
CRITICAL
USE
The
U.
S.
nomination
is
only
for
those
facilities
where
the
use
of
alternatives
is
not
suitable.
In
U.
S.
food
processing
plants
there
are
several
factors
that
make
the
potential
alternatives
to
methyl
bromide
unsuitable.
These
include:
­
Pest
control
efficacy
of
alternatives:
the
efficacy
of
alternatives
may
not
be
comparable
to
methyl
bromide,
making
these
alternatives
technically
and/
or
economically
infeasible.
­
Geographic
distribution
of
the
facilities:
some
facilities
are
situated
in
areas
where
key
pests
usually
occur
at
lower
levels,
such
as
those
located
in
the
northern
part
of
the
U.
S.
In
such
cases,
the
U.
S.
is
only
nominating
a
CUE
for
facilities
where
the
key
pest
pressure
is
moderate
to
high.
­
Age
and
type
of
facility:
older
food
processing
facilities,
especially
those
constructed
of
wood,
experience
more
frequent
and
severe
pest
infestations
that
must
be
controlled
by
fumigation.
­
Constraints
of
the
alternatives:
some
types
of
commodities
(
e.
g.,
those
containing
high
levels
of
fats
and
oils)
prevent
the
use
of
heat
as
an
alternative
because
of
its
effect
on
the
final
product
(
e.
g.,
rancidity).
Further,
the
corrosive
nature
of
phosphine
on
certain
metals
Page
6
prevents
its
use
in
mechanical
and
electrical
areas
of
the
facilities.
Additionally,
both
phosphine
and
sulfuryl
fluoride
are
temperature
sensitive.
­
Transition
to
newly
available
alternatives:
Sulfuryl
fluoride
recently
received
a
Federal
registration
for
portions
of
this
sector.
California,
New
York
and
Alaska
have
not
registered
sulfuryl
fluoride
at
the
time
of
this
analysis.
Further,
it
will
take
some
time
for
applicators
to
be
trained
in
the
use
of
this
chemical
and
for
its
incorporation
into
a
pest
control
program.
A
registration
decision
concerning
the
establishment
of
sulfuryl
fluoride
tolerances
on
other
processed
food
ingredients
in
a
treated
facility
is
still
pending.
­
Delay
in
plant
operations:
e.
g.,
the
use
of
some
methyl
bromide
alternatives
can
add
a
delay
to
production
by
requiring
additional
time
to
complete
the
fumigation
process.
Production
delays
can
result
in
significant
economic
impacts
to
the
processors.

Over
the
last
decade,
food
processing
facilities
in
the
United
States
have
reduced
the
number
of
methyl
bromide
fumigations
by
incorporating
many
of
the
alternatives
identified
by
MBTOC.
The
most
critical
alternative
implemented
is
IPM
strategies,
especially
sanitation,
in
all
areas
of
a
facility.
Plants
are
now
being
monitored
for
pest
populations,
using
visual
inspections,
pheromone
traps,
light
traps
and
electrocution
traps.
When
insect
pests
are
found,
plants
will
attempt
to
contain
the
infestation
with
treatments
of
low
volatility
pesticides
applied
to
both
surfaces
and
cracks
and
crevices.
These
techniques
do
not
disinfest
a
facility
but
are
critical
in
monitoring
and
managing
pests.
However,
when
all
these
methods
fail
to
control
a
pest
problem,
facilities
will
resort
to
phosphine,
heat,
and
if
all
else
fails,
to
methyl
bromide.

Many
facilities
in
the
United
States
also
are
using
both
phosphine
and
heat
treatments
to
disinfest
at
least
portions
of
their
plants.
Phosphine,
alone
and
in
combination
with
carbon
dioxide,
is
often
used
to
treat
both
incoming
grains
and
finished
products.
Unfortunately,
phosphine
is
corrosive
to
copper,
silver,
gold
and
their
alloys.
These
metals
are
critical
components
of
both
the
computers
that
run
the
machines
as
well
as
some
of
the
machines
themselves.
Therefore,
phosphine
is
not
feasible
in
all
areas
of
food
processing
facilities.
Additionally,
phosphine
requires
more
time
to
kill
insect
pests
than
does
methyl
bromide,
so
plants
need
to
be
shut
down
longer
to
achieve
mortality,
resulting
in
economic
losses.
There
are
also
reports
of
stored
product
pests
becoming
resistant
to
phosphine
(
Taylor,
1989;
Bell,
2000;
Mueller,
2002).

Heat
treatments
have
a
number
of
problems
in
this
industry.
Not
all
areas
of
a
plant
can
be
efficiently
treated
with
heat.
Some
food
substances,
for
instance
oils
and
butters
will
become
rancid
with
heat
treatments.
Not
all
finished
food
products
can
be
heated
for
the
length
of
time
heat
is
required
for
efficient
kill
of
pests.
In
addition,
geography
of
the
United
States
plays
a
crucial
role
in
the
use
of
heat
treatments.
Food
processing
plants
in
the
northern
United
States
will
experience
winters
with
several
weeks
of
sustaining
temperatures
of
­
32
°
to
­
35
°
C
(­
30
°
to
­
25
°
F).
In
these
areas
plants
have
heaters
and
the
power
plants
have
the
capacity
to
supply
excess
power
as
needed.
However,
the
southern
and
parts
of
the
western
zones
of
the
United
States
are
geographically
quite
different.
Winter
temperatures
there
seldom
reach
 
1.2
°
C
(
30
°
F)
and
when
temperatures
should
fall
that
low,
it
is
typically
for
only
a
few
hours
one
night.
For
many
winters,
these
areas
of
the
U.
S.
don't
freeze
at
all.
Subsequently,
these
facilities
do
not
have
heaters,
nor
do
the
power
plants
have
enough
power
to
allow
them
to
heat
such
large
areas
and
sustain
the
temperatures
necessary
for
an
effective
kill
of
pest
populations.
Still,
many
Page
7
southern
and
western
facilities
use
heat
treatments
as
a
spot
treatment
whereas
the
northern
facilities
can
use
heat
treatments
more
extensively.

Sulfuryl
fluoride
was
registered
in
the
U.
S.
in
January
of
2004
for
rice
mills
and
flour
mills.
There
are
some
constraints
with
this
new
fumigant:
it
has
not
been
registered
in
California
or
New
York;
it
is
temperature
dependent;
and
it
requires
extensive
training
of
the
applicators
to
proficiently
use
the
computerized
fumigation
guide.
Several
mills
used
sulfuryl
fluoride
this
summer
to
fumigate
their
facilities.
The
industry
is
trying
to
incorporate
this
new
fumigant
into
their
best
management
practices.

LIST
ALTERNATIVE
TECHNIQUES
THAT
ARE
BEING
USED
TO
CONTROL
KEY
TARGET
PEST
SPECIES
IN
THIS
SECTOR
Many
of
the
MBTOC
not
in
kind
alternatives
to
methyl
bromide
are
critical
to
monitoring
pest
populations
and
managing
those
populations,
but
they
do
not
disinfest
food
processing.
The
most
critical
of
these
alternatives
are
sanitation
and
IPM
strategies.
Sanitation
is
important
and
constantly
addressed
in
management
programs
(
Arthur
and
Phillips
2003).
Cleaning
and
hygiene
practices
alone
do
not
reduce
pest
populations,
but
reportedly
improve
the
efficacy
of
insecticides
or
diatomaceous
earth
(
Arthur
and
Phillips
2003).
The
principles
of
IPM
are
to
utilize
all
available
chemical,
cultural,
biological,
and
mechanical
pest
control
practices.
These
include
pheromone
traps,
electrocution
traps,
and
light
traps
to
monitor
pest
populations.
If
pests
are
found
in
traps,
then
contact
insecticides
and
low
volatility
pesticides
are
applied
in
spot
treatments
for
surfaces,
cracks
and
crevices,
or
anywhere
the
pests
may
be
hiding.
These
applications
are
intended
to
restrict
pests
from
spreading
throughout
the
facility
to
try
to
avoid
a
plant
fumigation
(
Arthur
and
Phillips
2003).
However,
IPM
is
not
designed
to
completely
eliminate
pests
from
any
given
facility
or
to
ensure
that
a
facility
remains
free
from
infestation.
Although
FDA
allows
minimal
contamination
of
food
products,
U.
S.
consumers
have
a
zero
tolerance
for
visible
insect
contamination
in
their
food
products.
While
sanitation
and
IPM
strategies
are
used
to
manage
pest
populations
and
extend
the
time
between
methyl
bromide
fumigations,
neither
is
an
acceptable
alternative
to
methyl
bromide
under
high
pest
pressure.

Many
food
processing
facilities
in
the
United
States
also
use
heat
treatments
to
reduce
insect
populations.
However,
some
areas
(
electronics
and
electrical
portions)
of
facilities
are
sensitive
to
heat.
Heat
also
causes
rancidity
in
butters
and
oils
and
denatures
proteins
that
may
be
used
in
the
ingredients,
plus,
not
all
manufactured
products
can
be
heated
to
the
temperature
or
for
the
time
required
in
order
to
get
an
effective
kill
of
insect
pests.
Some
facilities,
due
to
construction,
are
unable
to
use
heat.
There
have
been
reports
of
structural
damage
resulting
from
heat
treatments.
Facilities
in
the
southern
and
western
parts
of
the
United
States
do
not
have
heat
Page
12
sources
on
the
premises
thereby
making
heat
fumigations
impractical
without
costly
investments
that
are
not
economically
feasible.

Phosphine,
alone
and
in
combination
with
carbon
dioxide,
is
used
to
fumigate
portions
of
food
processing
facilities.
Many
facilities
treat
incoming
raw
ingredients
and
their
storage
facilities
with
phosphine,
but
the
corrosive
nature
of
phosphine
limits
its
use
throughout
the
entire
plant,
especially
in
areas
with
electronic
components.
In
the
United
States
it
is
specifically
against
the
label
(
illegal)
to
fumigate
in
areas
with
susceptible
metals
(
at:
http://
oaspub.
epa.
gov/
pestlabl/
ppls).
Phosphine
is
also
problematic
in
that
some
stored
product
pests
are
developing
resistance
to
this
chemical
(
Taylor,
1989,
Bell,
2000,
Mueller,
2002).

Food
processing
facilities
in
the
United
States
have
incorporated
sanitation,
IPM
strategies,
heat
and
phosphine
and
yet,
on
occasion,
insect
pest
populations
will
still
become
too
high
and
a
facility
will
need
to
fumigate
with
methyl
bromide.
However,
by
employing
these
alternatives,
this
sector
has
been
able
to
lengthen
times
between
methyl
bromide
applications,
thereby
reducing
the
total
amount
of
methyl
bromide.
However,
in
some
areas
of
the
country,
information
suggests
that
some
processors
may
employ
a
marginal
strategy
without
major
economic
dislocation
if
given
a
reasonable
time
frame
for
the
transition.
The
assessment
of
need
was
adjusted
to
account
for
this.

HOW
HAS
THIS
SECTOR
REDUCED
THE
USE
AND
EMISSIONS
OF
METHYL
BROMIDE
IN
THE
SITUATION
OF
THE
NOMINATION?

By
using
sanitation
and
IPM
the
industry
has
been
able
to
reduce
methyl
bromide
use
by
extending
the
time
between
fumigations.
According
to
the
applicants,
10­
12
years
ago,
plants
in
the
southern
United
States
used
to
fumigate
with
methyl
bromide
as
much
as
4­
6
times
a
year.
Currently,
most
southern
facilities
have
reduced
the
number
of
methyl
bromide
fumigations
to
twice
a
year.
These
fumigations
are
typically
at
the
beginning
of
the
summer
when
pest
pressure
is
significantly
increasing
and
at
the
end
of
the
summer.

In
the
northern
regions
of
the
United
States,
IPM
strategies
and
sanitation
methods
have
enabled
some
of
these
facilities
to
fumigate
with
methyl
bromide
once
every
3
years,
and
a
few
facilities
have
gone
without
a
methyl
bromide
fumigation
for
almost
5
years.
The
facilities
in
the
northern
United
States
have
been
able
to
exploit
heat
treatments
more
extensively
than
their
southern
counterparts,
as
well
as
opening
up
facilities
during
extremely
cold
weather
for
extensive
cleaning
coupled
with
low
volatility
pesticides
(
organophosphates,
pyrethroids,
insect
growth
regulators,
botanicals)
at
the
perimeters.

Heat
Treatment
For
food
processing
facilities
which
are
able
to
convert
to
heat
treatment,
economic
losses
are
from
additional
production
downtimes
due
to
longer
fumigation
time
and
from
capital
expenditures
required
to
adopt
an
alternative.
There
are
other
food
processing
facilities
in
areas
of
United
States
where
heat
treatment
is
not
feasible.
Economic
losses
due
to
downtime
with
heat
treatment
are
persistent.

Potential
economic
losses
were
estimated
for
the
food­
processing
facilities
that
have
not
been
converted
to
heat
treatment.
This
analysis
only
covers
cases
where
heat
treatment
may
potentially
be
technically
feasible,
and
does
not
cover
situations
where
heat
would
degrade
the
commodity
being
processed
(
those
with
fats
and
edible
oils).
Economic
costs
in
the
post­
harvest
uses
of
the
food­
processing
sector
can
be
characterized
as
arising
from
three
contributing
factors.
First,
the
direct
pest
control
costs
are
increased
in
most
cases
because
heat
treatment
is
more
expensive,
and
labor
is
increased
because
of
longer
treatment
time
and
increased
number
of
treatments.
For
food­
processing
facilities
that
are
not
already
using
heat,
capital
expenditure
is
also
required
to
retrofit
them
suitable
for
heat
treatment.
Moreover,
additional
production
downtimes
for
the
use
of
alternatives
are
unavoidable.
Many
facilities
operate
at
or
near
full
production
capacity
and
alternatives
that
take
longer
than
methyl
bromide
or
require
more
Page
18
frequent
application
can
result
in
manufacturing
slowdowns,
shutdowns,
and
shipping
delays.
Slowing
down
production
would
result
in
additional
costs
to
the
methyl
bromide
users.
Economic
cost
per
1000
m3
was
calculated
as
the
additional
costs
of
methyl
bromide
if
methyl
bromide
users
had
to
replace
methyl
bromide
with
heat
treatment.
Implementations
of
heat
treatment
likely
have
substantial
cost
implications
to
the
facilities
that
have
not
been
converted
to
heat
in
the
food­
processing
sector.

The
four
economic
measures
in
Table
E.
1
through
E.
4
were
used
to
quantify
the
economic
impacts
to
post­
harvesting
uses
for
food­
processing.
The
four
economic
measures
are
not
independent
of
each
other
since
they
can
be
calculated
from
the
same
financial
data.
The
measures
do,
however,
complement
each
other
in
evaluating
the
CUE
applicant's
economic
viability.
These
measures
represent
different
ways
to
assess
the
economic
feasibility
of
methyl
bromide
alternatives
for
methyl
bromide
users.

Net
revenue
is
calculated
as
gross
revenue
minus
operating
costs.
This
is
a
good
measure
as
to
the
direct
losses
of
income
that
may
be
suffered
by
the
users.
It
should
be
noted
that
net
revenue
does
not
represent
net
income
to
the
users.
Net
income,
which
indicates
profitability
of
an
operation
of
an
enterprise,
is
gross
revenue
minus
the
sum
of
operating
and
fixed
costs.
Net
income
should
be
smaller
than
the
net
revenue
measured
in
this
analysis.
We
did
not
include
fixed
costs
because
it
is
often
difficult
to
measure
and
verify.

Production
downtime
is
estimated
at
almost
two
additional
days
per
heat
treatment.
Potential
economic
losses
associated
with
the
use
of
heat
treatment
also
include
the
cost
of
capital
investment.
The
estimated
economic
losses
are
shown
in
Tables
E.
1
through
E.
4.
The
estimated
economic
loss
as
a
percentage
of
net
revenue
are
over
50%
for
all
the
CUE
applicants
in
the
food­
processing
sector
and
over
100%
for
the
rice
millers
resulting
in
negative
net
revenues.

The
costs
of
using
sulfuryl
fluoride
were
also
estimated
in
Tables
14.1,
E.
1,
and
E.
4
for
rice
and
flour
millers.
For
purposes
of
this
analysis,
current
prices
of
sulfuryl
fluoride
and
equal
efficacy
with
methyl
bromide
were
assumed.
However,
if
methyl
bromide
were
not
available,
the
price
of
sulfuryl
fluoride
could
rise
in
the
future.

The
industries
that
use
methyl
bromide
for
commodity
fumigation
are,
in
general,
subject
to
limited
pricing
power,
changing
market
conditions,
and
government
regulations.
Companies
within
these
industries
operate
in
a
highly
competitive
global
marketplace
characterized
by
high
sales
volume,
low
profit
margins,
and
rapid
turnover
of
inventories.
The
results
suggest
that
heat
treatment
is
not
economically
viable
as
an
alternative
for
methyl
bromide
in
existing
facilities
that
still
use
methyl
bromide.

17.1.
Research
The
number
of
available
insecticides
that
can
be
used
in
and
around
food
plants,
processing
mills,
and
food
warehouses
in
the
U.
S.
has
declined
in
recent
years.
The
research
and
development
of
chemical
alternatives
to
be
used
by
this
sector
is
a
critical
need
in
the
U.
S.
The
post­
harvest
food­
processing
sector
has
invested
substantial
time
and
funding
into
research
and
development
of
technically
and
economically
feasible
alternatives
to
methyl
bromide.
Past
and
current
research
focuses
on
the
biology
and
ecology
of
the
pests,
primarily
insect
pests.
To
implement
non­
chemical
controls
and
reduce
methyl
bromide
use
requires
a
thorough
understanding
of
the
pests
in
order
to
exploit
their
weaknesses.
Some
of
these
investigations
have
studied
the
effects
of
temperature
and
humidity
on
the
fecundity,
development,
and
longevity
of
a
specific
species.
Other
studies
have
been
to
determine
the
structural
preferences
and
microhabitat
requirements
of
a
species.
Studies
of
factors
affecting
population
growth
(
interactions
within
and
among
species)
have
been
conducted.
However,
there
is
still
much
research
that
needs
to
be
done.

IPM
and
sanitation
methods
are
also
under
investigation.
Studies
have
focused
on
food
plant
design,
engineering
modifications
for
pest
exclusion,
and
insect­
resistant
packaging.
New
research
is
demonstrating
a
potential
to
incorporate
chemical
repellents
into
packaging
materials
(
Arthur
and
Phillips
2003).
Further
studies
with
pheromones
and
trapping
strategies
are
helping
to
improve
IPM
in
food
processing
plants.

The
USDA
is
continuing
to
fund
research
projects
for
post­
harvest/
food
processing
plants.
Such
activities
include:

Biology

chemicals
combined
with
nonchemical
methodologies
which
will
yield
integrated

programs;
and
develop
methods
to

The
rice
milling
industry
has
spent
over
U.
S.$
500,000
on
research
to
develop
alternatives
since
1992,
and
plans
to
use
additional
pesticides,
such
as
carbonyl
sulfide,
carbon
dioxide,
phosphine,
magnesium
phosphide
(
magtoxin),
and
dichlorvos
(
vapona)
over
the
next
few
years.
Nonchemical
methods
used
by
this
sub­
sector,
to
reduce
methyl
bromide
use,
include
heat
and
cold
treatments,
and
many
individual
companies
are
involved
in
further
research
and
testing
of
alternatives.
Industry
experts
have
been
trying
to
determine
how
best
to
incorporate
sulfuryl
fluoride
into
their
IPM
programs
since
its
recent
registration.

The
bakery
sector
is
implementing
heat
as
an
alternative
at
those
facilities
where
heat
is
technically
feasible.
Currently,
heat
is
being
implemented
at
several
facilities
nationwide,
but
further
trials
are
needed
to
determine
the
effects
of
heat
on
a
long­
term
basis.
However,
older
facilities
with
hardwood
floors
and
plant
electrical
wiring
systems
are
unsuitable
for
heat
treatments.
Other
methods
being
used
to
reduce
reliance
on
methyl
bromide
are:
exclusion,
cleaning,
early
detection,
improved
design
of
equipment,
trapping,
and
other
integrated
pest
management
(
IPM)
approaches.
Phosphine
continues
to
be
tested.

The
flour
milling
industry
is
committed
to
IPM
techniques
in
order
to
minimize
reliance
on
any
one
tool.
Many
plants
have
reduced
the
amount
of
annual
fumigations
from
4­
5
per
year
to
2­
3
per
year.
Some
of
these
facilities
combine
methyl
bromide
with
carbon
dioxide.
Further,
these
applicants
have
authored
three
manuals
on
fumigation
best
practices,
which
are
widely
utilized
throughout
the
industry.
The
industry
continues
to
test
high
heat,
phosphine,
alone
and
in
combination;
and
the
combination
of
heat,
phosphine,
and
carbon
dioxide.
In
addition,
industry
experts
have
been
trying
to
determine
how
best
to
incorporate
sulfuryl
fluoride
into
their
IPM
programs
since
its
recent
registration.

The
Pet
Food
Institute
has
invested
hundreds
of
thousands
of
dollars
in
research
on
a
variety
of
alternatives
to
methyl
bromide,
including
heat
treatments.
Sulfuryl
fluoride
was
tested
in
an
inactive
pet
food
facility
last
year
as
well.
They
have
made
improvements
in
worker
training,
pest
monitoring,
and
sanitation
to
greatly
reduce
the
necessity
for
fumigations
with
methyl
bromide,
or
any
other
fumigant.

Registration
Since
1997,
the
U.
S.
EPA
has
made
the
registration
of
alternatives
to
methyl
bromide
a
high
registration
priority.
Because
the
U.
S.
EPA
currently
has
more
applications
pending
in
its
registration
review
queue
than
the
resources
to
evaluate
them,
U.
S.
EPA
prioritizes
the
applications.
By
virtue
of
being
a
top
registration
priority,
methyl
bromide
alternatives
enter
the
science
review
process
as
soon
as
U.
S.
EPA
receives
the
application
and
supporting
data
rather
than
waiting
in
turn
for
the
U.
S.
EPA
to
initiate
its
review.

As
one
incentive
for
the
pesticide
industry
to
develop
alternatives
to
methyl
bromide,
the
Agency
has
worked
to
reduce
the
burdens
on
data
generation,
to
the
extent
feasible
while
still
ensuring
that
the
Agency's
registration
decisions
meet
the
Federal
statutory
safety
standards.
Where
appropriate
from
a
scientific
standpoint,
the
Agency
has
refined
the
data
requirements
for
a
given
pesticide
application,
allowing
a
shortening
of
the
research
and
development
process
for
the
methyl
bromide
alternative.
Furthermore,
Agency
scientists
routinely
meet
with
prospective
methyl
bromide
alternative
applicants,
counseling
them
through
the
preregistration
process
to
increase
the
probability
that
the
data
is
done
right
the
first
time
and
rework
delays
are
minimized
The
U.
S.
EPA
has
also
co­
chaired
the
USDA/
EPA
Methyl
Bromide
Alternatives
Work
Group
since
1993
to
help
coordinate
research,
development
and
the
registration
of
viable
alternatives.
This
coordination
has
resulted
in
key
registration
issues
(
such
as
worker
and
bystander
exposure
through
volatilization,
township
caps
and
drinking
water
concerns)
being
directly
addressed
through
USDA's
Agricultural
Research
Service's
U.
S.$
15
million
per
year
research
program
conducted
at
more
than
20
field
evaluation
facilities
across
the
country.
Also
U.
S.
EPA's
participation
in
the
evaluation
of
research
grant
proposals
each
year
for
USDA's
U.
S.$
2.5
million
per
year
methyl
bromide
alternatives
research
has
further
ensured
close
coordination
between
the
U.
S.
government
and
the
research
community.

Since
1997,
the
U.
S.
EPA
has
registered
the
following
chemical/
use
combinations
as
part
of
its
commitment
to
expedite
the
review
of
methyl
bromide
alternatives:

 
2000:
Phosphine
in
combination
to
control
stored
product
insect
pests
 
2001:
Indianmeal
Moth
Granulosis
Virus
to
control
Indianmeal
moth
in
stored
grains
 
2004:
Sulfuryl
fluoride
as
a
post­
harvest
fumigant
for
stored
commodities
and
some
mills
(
see
below).

17.2.1.
Sulfuryl
Fluoride
On
January
23,
2004,
U.
S.
EPA
registered
sulfuryl
fluoride
as
a
post­
harvest
fumigant
for
grains
and
flour
mills.
While
registration
for
these
uses
will
provide
opportunities
to
reduce
methyl
bromide
use,
it
must
be
emphasized
that
such
replacement,
if
feasible,
will
only
occur
gradually
over
time.

Alternatives
must
be
tested
by
users
and
found
technically
and
economically
feasible
before
widespread
adoption
will
occur.
As
noted
by
TEAP,
a
specific
alternative,
once
available
may
Page
24
take
up
to
5
fumigation
cycles
of
use
before
efficacy
can
be
determined
in
the
specific
circumstance
of
the
user.
The
registrant
is
requiring
that
applicators
be
trained
by
them
before
using
sulfuryl
fluoride
(
there
is
a
3­
tiered
certification
system).
Several
fumigation
companies
have
teams
trained
by
the
registrant.
Mills
have
begun
testing
sulfuryl
fluoride
in
specific
circumstances.

There
are
additional
pesticide
registration
issues,
however,
that
must
be
resolved
before
sulfuryl
fluoride
can
be
used
in
sectors
for
which
the
U.
S.
is
nominating
methyl
bromide
CUEs.
Sulfuryl
fluoride
is
being
registered
only
for
cereal
and
small
grains
and
mills
that
contain
and/
or
process
these
grains.
Many
mills
also
produce
partial
recipe
products
that
contain
such
ingredients
as
sugar,
leavening
agents,
hydrogenated
oils,
etc.
The
registration
of
sulfuryl
fluoride
does
not
include
tolerances
for
these
ingredients
and
therefore
would
not
be
allowed
in
these
facilities.
It
is
most
likely
that
adoption
of
sulfuryl
fluoride
for
some
of
these
mills
will
be
delayed
until
tolerances
for
these
ingredients
are
sought
by
the
registrant,
reviewed
by
U.
S.
EPA,
and
granted
(
if
they
meet
eligibility
criteria).

States
must
also
register
sulfuryl
fluoride.
All
states
except
California,
New
York,
and
Alaska
have
registered
sulfuryl
fluoride
for
these
post
harvest
uses.

U.
S.
EPA
currently
has
limited
data
on
sulfuryl
fluoride's
performance
relative
to
methyl
bromide.
We
have
little
product
performance
data
(
direct
comparisons
to
methyl
bromide),
no
experience
in
how
well
it
performs
in
different
facilities
and
climates
over
multiple
years,
and
no
information
on
what
costs
might
be
associated
with
adopting
sulfuryl
fluoride.
Based
on
the
limited
data
currently
available,
U.
S.
EPA
believes
that
within
4
years
sulfuryl
fluoride
may
be
able
to
replace
methyl
bromide
in
up
to
75%
of
the
rice
and
flour
mills.
U.
S.
EPA
is
committed
to
monitoring
sulfuryl
fluoride
use
during
the
next
few
years
to
amend
future
CUE
nominations.

ADDITIONAL
COMMENTS
Pheromone
Traps
"
One
misconception
about
pheromone
traps
is
that
a
pest
population
can
be
controlled
by
deploying
these
traps
 
that
is
not
true
for
most
situations.
Traps
usually
attract
only
a
small
percentage
of
the
population
that
is
within
the
effective
range
of
the
trap.
Also,
female­
produced
sex
pheromones
attract
only
males;
the
females
that
lay
eggs
and
perpetuate
the
infestation
are
not
affected.
Since
males
of
the
many
insect
species
will
mate
with
multiple
females,
any
males
that
are
not
trapped
can
easily
contribute
to
the
production
of
a
subsequent
generation
of
pests.
New
methods
are
being
researched
for
using
pheromones
in
pest
suppression,
but
current
uses
of
pheromone
traps
are
best
used
only
for
monitoring
purposes."

and
Phillips

Sulfuryl
Fluoride
There
are
some
industry
concerns
regarding
sulfuryl
fluoride.
Primarily
that
it
is
temperature
dependent
and
that
large
concentrations
are
necessary
to
kill
eggs.
There
is
concern
regarding
mixing
of
bulk
flour
at
a
10:
1
ratio
to
meet
tolerances.
The
post
harvest
industry
is
aware
that
sulfuryl
fluoride,
as
Vikane
®
,
is
very
expensive
and
they
are
very
concerned
that
the
price
of
Page
25
sulfuryl
fluoride
as
Profume
®
may
be
prohibitive
to
use
at
the
concentrations
required
to
control
pests.

There
have
been
a
few
reported
problems
with
sulfuryl
fluoride
fumigations.
One
facility
(
ca
28,317
m3
or1
million
ft3)
was
treated
at
a
"
less
than
all
life
stages"
level,
which
did
not
control
the
insect
infestation.
Additionally,
that
particular
mill
is
typically
fumigated
with
817
kg
(
1,800
lb)
methyl
bromide,
but
the
May
fumigation
required
1,506
kg
(
3,321
lb)
sulfuryl
fluoride.
This
mill
needed
to
be
fumigated
with
methyl
bromide
about
8
weeks
later.
In
this
same
facility,
the
calculated
amount
of
sulfuryl
fluoride
was
2,371
kg
(
5,226
lb)
for
"
complete
kill",
at
30
º
C
(
86
º
F).
A
facility
of
similar
size
intended
to
fumigate
at
Thanksgiving,
but
the
temperature
would
require
5,897
kg
(
13,000
lb)
sulfuryl
fluoride
for
"
complete
kill."
That
facility
decided
to
go
with
a
methyl
bromide
fumigation
based
on
volumes.

On
page
6
of
the
sulfuryl
fluoride
label:
" 
bulk 
wheat
flour
not
removed
from
the
fumigation
area
must
be
blended
at
a
ratio
of
at
least
10:
1
or
discarded
to
ensure
wheat
flour
offered
to
consumers
does
not
exceed
commodity
tolerances."
Many
of
the
millers
do
not
have
the
capacity
to
mix
the
fumigated
bulk
flour
and
are
therefore
finding
this
requirement
to
be
a
very
difficult
one
to
achieve.

APPENDIX
D.
2006
Methyl
Bromide
Reconsideration
for
Rice
Mills
Overview
of
the
U.
S.
Nomination
The
U.
S.
requested
505.982
metric
tons
of
methyl
bromide
for
use
in
mills
and
food
processing
facilities
for
2006.
The
request
was
distributed
as
follows:
114.305
metric
tons
for
rice
mills,
14.742
metric
tons
for
bakeries,
48.081
metric
tons
for
pet
food
facilities,
and
328.854
metric
tons
for
flour
mills.
This
is
a
request
at
the
national
level.

The
U.
S.
nomination
is
only
for
those
facilities
where
the
use
of
alternatives
is
not
suitable.
In
U.
S.
food
processing
plants
there
are
several
factors
that
make
the
potential
alternatives
to
methyl
bromide
unsuitable.
These
include:
­
Pest
control
efficacy
of
alternatives:
the
efficacy
of
alternatives
may
not
be
comparable
to
methyl
bromide,
making
these
alternatives
technically
and/
or
economically
infeasible.
­
Geographic
distribution
of
the
facilities:
some
facilities
are
situated
in
areas
where
key
pests
may
occur
at
low
levels,
such
as
those
located
in
the
northern
part
of
the
U.
S.
In
such
cases,
the
U.
S.
is
only
nominating
a
CUE
for
facilities
where
the
key
pest
pressure
is
moderate
to
high.
­
Age
and
type
of
facility:
older
food
processing
facilities,
especially
those
constructed
of
wood,
experience
more
frequent
and
severe
pest
infestations
that
must
be
controlled
by
fumigation.
­
Constraints
of
the
alternatives:
some
types
of
commodities
(
e.
g.,
those
containing
high
levels
of
fats
and
oils)
prevent
the
use
of
heat
as
an
alternative
because
of
its
effect
on
the
final
product
(
e.
g.,
rancidity).
Further,
the
corrosive
nature
of
phosphine
on
certain
metals
prevents
its
use
in
mechanical
and
electrical
areas
of
the
facilities.

Transition
to
newly
available
alternatives:
Sulfuryl
fluoride
recently
received
a
Federal
registration
for
small
grains
such
as
flour,
rice,
oats,
etc.
State
registrations
have
not
yet
been
issued
for
all
states.
Further,
it
will
take
some
time
for
applicators
to
be
trained
in
the
use
of
this
chemical
and
for
its
incorporation
into
a
pest
control
program.
A
registration
decision
concerning
the
establishment
of
sulfuryl
fluoride
tolerances
on
other
processed
food
ingredients
in
a
treated
facility
is
still
pending.
­
Delay
in
plant
operations:
e.
g.,
the
use
of
some
methyl
bromide
alternatives
can
add
a
delay
to
production
by
requiring
additional
time
to
complete
the
fumigation
process.
Production
delays
can
result
in
significant
economic
impacts
to
the
processors.

MBTOC
recommended
a
total
of
394.843
metric
tons
of
methyl
bromide
for
this
sector
distributed
as
follows:
73.745
metric
tons
for
rice
mills,
14.742
metric
tons
for
bakery
uses,
43.273
for
dry
pet
food
premises,
and
263.083
for
flour
mills.
The
total
recommendation
was
for
394.843
metric
tons
of
methyl
for
these
uses
in
2006.

MBTOC
stated
that
proper
sealing
should
allow
rice
mills
to
reduce
their
use
rate
from
31g/
m
3
to
20
g/
m3.
Although
there
is
no
evidence
that
proper
sealing
procedures
are
not
followed
and
that
is
the
reason
for
the
higher
use
rate
than
is
common
for
the
remainder
of
the
sector,
USG
agrees
that
in
general,
a
use
rate
of
20g/
m3
should
allow
for
adequate
control
of
pests
but
reserves
the
right
to
re­
visit
this
issue
should
we
become
aware
of
data
demonstrating
that
this
level
is
not
adequate
to
control
pests
in
the
specific
circumstances
of
the
nomination
when
Page
37
appropriate
practices
(
eg
careful
sealing
of
the
building/
container
and
other
`
best
practices')
are
followed.
This
reduction
results
in
an
amended
U.
S.
request
of
73.745
metric
tons
of
methyl
bromide
for
this
portion
of
the
sector
as
recommended
by
MBTOC.

MBTOC
appears
to
believe
that
better
sealing
in
rice
facilities
is
necessary
because
they
believe
that
facilities
are
treated
five
times
per
year.
In
this
industry,
the
majority
of
the
milling
facilities
are
old
and
located
in
the
southern
US1
(
close
to
where
rice
is
produced
in
Florida,
Texas,
Louisiana,
Arkansas
and
California)
where
pest
pressures
are
high
and
where
insects
are
able
to
survive
easily
when
driven
outdoors
by
fumigation.
In
addition,
bringing
new
batches
of
rice
into
the
facilities
can
result
in
a
re­
infestation.
USG
does
not
think
that
there
is
further
scope
for
reduction
in
rice
mills.

MBTOC
recommended
that
the
use
rate
for
pet
food
facilities
be
reduced
from
22
to
20
g/
m3.
USG
agrees
that
in
general,
a
use
rate
of
20g/
m3
should
allow
for
adequate
control
of
pests
but

This

results
in
an
amended
U.
S.
request
of
44.417
metric
tons
of
methyl
bromide
for
this
portion
of
the
sector,
an
increase
of
1.144
metric
tons
over
the
MBTOC
recommended
amount
of
43.273
metric
tons
MBTOC
further
recommended
that
the
request
for
methyl
bromide
used
in
pet
food
facilities
be
reduced
by
10%
"
to
allow
progressive
adoption
of
fumigant
alternatives
such
as
sulfuryl
fluoride
(
recently
registered
for
flour
mills
(
sic)
2,
continuing
adoption
of
heat
technologies,
improved
sealing
of
buildings,
and
increased
optimization
of
IPM
techniques."

Sulfuryl
fluoride
is
not
registered
for
use
on
dry
pet
food.
There
is
at
present
a
legal
question
as
to
whether
a
registration
is
required
(
authorizing
statute
refers
to
"
foods
for
human
and
other
animals")
or
not
required.
Until
this
issue
is
clarified
sulfuryl
fluoride
cannot
be
used
on
pet
foods.

MBTOC
has
recommended
a
further
reduction
of
10%
in
the
amount
of
methyl
bromide
that
can
be
used
to
fumigate
flour
mills,
citing
increased
adoption
of
sulfuryl
fluoride
in
particular,
and
adoption
of
other
alternatives
more
generally.

Addressing
first
the
issue
of
sulfuryl
fluoride;
as
already
noted,
sulfuryl
fluoride
is
not
registered
in
all
States,
nor
is
it
registered
on
the
additional
components
that
transform
flour
into
bread,
cake,
pancake
and
other
mixes.
It
cannot,
therefore,
be
used
at
all
in
some
jurisdictions
nor
can
it
be
used
in
many
areas
of
`
combined'
processing
facilities.

1
Location
of
the
facilities
is
dictated
by
close
proximity
to
the
raw
ingredients
and
to
major
markets.
For
example,
the
22
rice
mills
are
located
primarily
in
Gulf
Coast
states
and
California.
2
There
is
a
Federal
registration
for
sulfuryl
fluoride
use
in
flour
mills,
rice
mills,
and
other
small
grain
mills,
however,
many
states
have
registration
requirements
in
addition
to
the
Federal
requirements
and
until
a
pesticide
has
obtained
a
state
`
label'
it
cannot
be
used.
At
present
Sulfuryl
Fluoride
is
registered
in
neither
California
nor
New
York
and
so
cannot
be
use
in
those
states.

The
Montreal
Protocol
calls
for
a
critical
use
nomination
being
granted
when
there
are
no
alternatives
that
are
both
technically
and
economically
feasible,
There
are
companies
that
have
committed
themselves
to
using
alternatives
to
methyl
bromide
regardless
of
the
cost
differences
as
long
as
they
can
continue
to
meet
necessary
sanitary
standards.
One
such
company
shared
their
experience
with
sulfuryl
fluoride
with
us3
A
nine
story
flour
mill
(
1.2
million
cubic
feet4)
was
fumigated
with
sulfuryl
fluoride.
The
fumigation
took
place
from
October
1st
to
October
3rd.
When
this
facility
has
been
fumigated
with
methyl
bromide
the
typical
amount
used
has
been
between
1200
and
1500
lbs5.
The
fumigation
with
sulfuryl
fluoride
used
5250
lbs.
at
a
temperature
of
826
F
over
a
36
hour
rather
than
a
24
hour
period.
Although
fumigation
with
sulfuryl
fluoride
requires
that
the
material
be
left
in
place
for
a
longer
period
than
is
required
for
methyl
bromide,
this
component
does
not
add
to
the
cost
of
the
alternative
in
this
instance
as
it
is
the
practice
of
this
company
to
conduct
fumigations
over
a
three
day
period
to
allow
adequate
time
for
preparation
and
for
the
gas
to
dissipate
at
the
conclusion
of
the
fumigation.

The
cost
of
a
methyl
bromide
fumigation
is
approximately
$
18,500
of
which
approximately
30­
40%
is
the
cost
of
the
chemical.
The
remaining
costs
are
preparing
and
sealing
the
building,
monitoring,
and
unsealing
at
the
conclusion
of
the
fumigation.
The
cost
of
the
sulfuryl
fluoride
fumigation
was
$
48,000,
nearly
three
times
the
cost
of
the
methyl
bromide
fumigation.
The
ancillary
costs
(
prepping,
sealing,
monitoring,
unsealing,
etc.)
are
the
same
for
both
treatments,
the
cost
difference
is
due
to
the
difference
in
the
price
and
amount
used
of
the
sulfuryl
fluoride.

At
present
the
company
that
produces
sulfuryl
fluoride
is
offering
sulfuryl
fluoride
at
a
price
per
pound
that
is
equal
to
or
below
the
price
of
methyl
bromide.
What
is
not
known
is
whether
this
practice
will
continue
when
methyl
bromide
is
no
longer
available.
There
is
currently
a
sulfuryl
fluoride
product
(
Vikane
®
)
that
is
registered
for
non­
food
uses7.
The
market
price
is
$
10/
lb.
Although
we
expect
that
the
food
use
sulfuryl
fluoride
(
Profume
®
)
to
be
less
expensive,
it
is
currently
impossible
to
determine
the
market
price.
This
compares
to
a
methyl
bromide
cost
of
approximately
$
1.5
to
$
3.0
per
pound.

Over
the
last
decade,
food
processing
facilities
in
the
United
States
have
reduced
the
number
of
methyl
bromide
fumigations
by
incorporating
many
of
the
alternatives
identified
by
MBTOC.
The
most
critical
alternative
implemented
is
IPM
strategies,
especially
sanitation,
in
all
areas
of
a
facility.
Plants
are
now
being
monitored
for
pest
populations,
using
visual
inspections,
pheromone
traps,
light
traps
and
electrocution
traps.
When
insect
pests
are
found,
plants
will
attempt
to
contain
the
infestation
with
treatments
of
low
volatility
pesticides
applied
to
both
surfaces
and
cracks
and
crevices.
These
techniques
do
not
disinfest
a
facility
but
are
critical
in

The
company
has
requested
confidentiality.
There
is
great
concern
within
the
industry
that
the
perception
that
food
facilities
are
infested
with
pests
not
become
widespread.
There
was
great
fear
on
the
part
of
company
officials
that
if
the
company
is
identified
with
a
pest
management
issue
the
public
will
boycott
its
products,
feeling
them
(
wrongly)
to
be
unsanitary.
The
discussion
was
arranged
under
the
auspices
of
the
North
American
Millers
Association
and
took
place
in
Arlington
Virginia
in
November
of
2004.

monitoring
and
managing
pests.
However,
when
all
these
methods
fail
to
control
a
pest
problem,
facilities
will
resort
to
phosphine,
heat,
and
if
all
else
fails,
to
methyl
bromide.

Many
facilities
in
the
United
States
also
are
using
both
phosphine
and
heat
treatments
to
disinfest
at
least
portions
of
their
plants.
Phosphine,
alone
and
in
combination
with
carbon
dioxide,
is
often
used
to
treat
both
incoming
grains
and
finished
products.
Unfortunately,
phosphine
is
corrosive
to
copper,
silver,
gold
and
their
alloys.
These
metals
are
critical
components
of
both
the
computers
that
run
the
machines
as
well
as
some
of
the
machines
themselves.
In
the
United
States
it
is
specifically
against
the
label
(
illegal)
to
fumigate
in
areas
with
susceptible
metals
(
at:
http://
oaspub.
epa.
gov/
pestlabl/
ppls).
Therefore,
phosphine
is
not
feasible
in
all
areas
of
food
processing
facilities.
Additionally,
phosphine
requires
more
time
to
kill
insect
pests
than
does
methyl
bromide,
so
plants
need
to
be
shut
down
longer
to
achieve
mortality,
resulting
in
economic
losses.
There
are
also
reports
of
stored
product
pests
becoming
resist
to
phosphine
(
Taylor,
1989;
Bell,
2000;
Mueller,
2002).

Heat
treatments
have
a
number
of
problems
in
this
industry.
Not
all
areas
of
a
plant
can
be
efficiently
treated
with
heat.
Some
food
substances,
for
instance
oils
and
butters
will
become
rancid
with
heat
treatments.
Not
all
finished
food
products
can
be
heated
for
the
length
of
time
heat
is
required
for
efficient
kill
of
pests.
In
addition,
geography
of
the
United
States
plays
a
crucial
role
in
the
use
of
heat
treatments.
Food
processing
plants
in
the
northern
United
States
will
experience
winters
with
several
weeks
of
sustaining
temperatures
of
­
32
°
to
­
35
°
C
(­
30
°
to
­
25
°
F).
In
these
areas
plants
have
heaters
and
the
power
plants
have
the
capacity
to
supply
excess
power
as
needed.
However,
the
southern
and
parts
of
the
western
zones
of
the
United
States
are
geographically
quite
different.
Winter
temperatures
there
seldom
reach
 
1.2
°
C
(
30
°
F)
and
when
temperatures
should
fall
that
low,
it
is
typically
for
only
a
few
hours
one
night.
For
many
winters,
these
areas
of
the
U.
S.
don't
freeze
at
all.
Subsequently,
these
facilities
do
not
have
heaters,
nor
do
the
power
plants
have
enough
power
to
allow
them
to
heat
such
large
areas
and
sustain
the
temperatures
necessary
for
an
effective
kill
of
pest
populations.
Additionally,
escaping
insects
can
survive
these
outdoor
temperatures
and
re­
enter
the
facility
after
treatment,
even
when
low
volatility
pesticides
are
used
to
treat
the
surfaces
exiting
the
plant.
Still,
many
southern
and
western
facilities
use
heat
treatments
as
a
spot
treatment
whereas
the
northern
facilities
can
use
heat
treatments
more
extensively.

Potential
economic
losses
were
estimated
for
the
food­
processing
facilities
that
have
not
been
converted
to
heat
treatment.
This
analysis
only
covers
cases
where
heat
treatment
may
potentially
be
technically
feasible,
and
does
not
cover
situations
where
heat
would
degrade
the
commodity
being
processed
(
those
with
fats
and
edible
oils).
Economic
costs
in
the
post­
harvest
uses
of
the
food­
processing
sector
can
be
characterized
as
arising
from
three
contributing
factors.
First,
the
direct
pest
control
costs
are
increased
in
most
cases
because
heat
treatment
is
more
expensive,
and
labor
is
increased
because
of
longer
treatment
time
and
increased
number
of
treatments.
For
food­
processing
facilities
that
are
not
already
using
heat,
capital
expenditure
is
also
required
to
retrofit
them
suitable
for
heat
treatment.
Moreover,
additional
production
downtimes
for
the
use
of
alternatives
are
unavoidable.
Many
facilities
operate
at
or
near
full
production
capacity
and
alternatives
that
take
longer
than
methyl
bromide
or
require
more
frequent
application
can
result
in
manufacturing
slowdowns,
shutdowns,
and
shipping
delays.
Slowing
down
production
would
result
in
additional
costs
to
the
methyl
bromide
users.
Page

Economic
cost
per
1000
m3
was
calculated
as
the
additional
costs
of
methyl
bromide
if
methyl
bromide
users
had
to
replace
methyl
bromide
with
heat
treatment.
Implementations
of
heat
treatment
likely
have
substantial
cost
implications
to
the
facilities
that
have
not
been
converted
to
heat
in
the
food­
processing
sector.

Production
downtime
was
estimated
at
two
more
days
per
fumigation
with
heat
and
total
capital
expenditures
for
heat
treatment
was
assumed
to
be
$
1,076
per
1000
m3
with
10­
years
lifespan
with
10%
interest
rate
from
the
data
provided
by
the
CUE
applicants
for
post­
harvesting
uses.
The
potential
economic
losses
associated
with
the
use
of
heat
treatment
mainly
originate
from
the
cost
of
capital
investment.
The
estimated
economic
loss
per
1000
m3
ranges
from
$
2,023
for
rice
milling
to
$
12,439
for
flour/
grain
milling.
The
estimated
economic
losses
as
a
percentage
of
gross
revenue
ranges
from
3%
to
18%
and
the
estimated
economic
loss
as
a
percentage
of
net
revenue
are
over
45%
for
all
the
CUE
applicants
in
the
food­
processing
sector.
The
industries
that
use
methyl
bromide
for
commodity
fumigation
are,
in
general,
subject
to
limited
pricing
power,
changing
market
conditions,
and
government
regulations.
Companies
within
these
industries
operate
in
a
highly
competitive
global
marketplace
characterized
by
high
sales
volume,
low
profit
margins,
and
rapid
turnover
of
inventories.
The
results
suggest
that
heat
treatment
is
not
economically
viable
as
an
alternative
for
methyl
bromide
in
existing
facilities
that
still
use
methyl
bromide.

For
these
reasons,
both
technical
and
economic,
USG
does
not
believe
it
is
appropriate
to
assume
that
alternatives
that
are
both
technically
and
economically
feasible
will
be
available
to
substitute
for
currently
used
methyl
bromide
in
flour
mills
and
is
requesting
that
the
full
request
of
328.854
metric
tons
of
methyl
bromide,
which
is
an
additional
65.771
metric
tons
of
methyl
bromide
over
the
MBTOC
recommended
amount
of
263.083
metric
tons.

of
MBTOC/
TEAP
Report.

We
have
not
been
provided
by
MBTOC
with
information
on
the
technical
assessment
of
the
performance
of
alternatives,
or
the
economic
assessment
on
the
impact
of
converting
to
alternatives.
To
support
the
MBTOC's
recommended
change
in
the
U.
S.
request
citations
of
the
research
references
and
economic
assessments
that
led
to
the
MBTOC
conclusions
are
needed
so
we
can
understand
the
justification.
The
technical
references
should
describe
the
species
tested,
pest
numbers,
concentrations,
times,
and
commodity
volumes.
Economic
references
should
describe
the
costs
of
converting
from
methyl
bromide
to
alternatives,
and
the
economic
feasibility
of
sulfuryl
fluoride
if
it
must
be
used
at
a
higher
rate
than
methyl
bromide.

U.
S.
2006
nomination
The
USG
is
requesting
an
additional
66.915
metric
tons
of
methyl
bromide
for
2006
over
the
MBTOC
recommended
amount
of
394.843
metric
tons
for
use
in
flour
mills.
This
represents
an
amended
request
of
461.758
metric
tons
rather
than
the
505.982
metric
tons
of
methyl
bromide
originally
requested.
