Although
REFS
identifies
this
product
as
a
technical,
the
Methyl
Bromide
Update
determined
that
this
product
is
actually
an
FI.

REGULATORY
BACKGROUND
The
Methyl
Bromide
Reregistration
Standard
issued
3/
28/
86
required
additional
product
chemistry
data
concerning
methyl
bromide.
The
Methyl
Bromide
Guidance
Document
dated
8/
86
required
that
all
new
product
chemistry
data
be
submitted
for
the
reregistration
of
methyl
bromide
because
new
requirements
had
been
introduced
and
previously
submitted
data
needed
to
be
updated.
Data
submitted
in
response
to
the
Guidance
Document
for
the
MPs
were
evaluated
in
Agency
reviews
and
in
the
Methyl
Bromide
Reregistration
Standard
Update
dated
6/
21/
91
with
regard
to
adequacy
in
fulfilling
product
chemistry
requirements.
Data
in
support
of
registration/
reregistration
have
been
submitted
by
the
Methyl
Bromide
Industry
Panel
(
MBIP)
which
consists
of
the
following
members:
Albemarle
Corporation,
Great
Lakes
Chemicals
Corporation,
Ameribrom,
Inc.,
and
Trical,
Inc.
The
Methyl
Bromide
Update
summarized
the
available
product
chemistry
database
and
required
additional
data
for
the
Ameribrom,
Albemarle,
and
Great
Lakes
Chemical
T/
TGAIs
and
formulation
intermediates
(
FIs).

As
a
safety
measure,
the
Guidance
Document
required
that
end­
use
products
with
methyl
bromide
as
the
active
ingredient,
which
will
be
used
for
any
purpose
other
than
the
fumigation
of
RACs
in
enclosed
chambers,
contain
0.25­
2.0%
chloropicrin
as
an
odor
warning
agent.
Chloropicrin
at
this
concentration
is
considered/
listed
as
an
inert
ingredient.

The
current
status
of
the
product
chemistry
data
requirements
for
the
methyl
bromide
T/
TGAIs
and
FIs
is
presented
in
the
attached
data
summary
tables.
Refer
to
these
tables
for
a
listing
of
the
outstanding
product
chemistry
data
requirements.

CONCLUSIONS
Most
pertinent
product
chemistry
requirements
data
have
been
satisfied
for
the
Ameribrom
100%
and
Albemarle
99.8%
T/
TGAIs,
and
for
the
Albemarle
98%
FI;
however,
additional
data
are
required
for
the
T/
TGAIs
concerning
oxidation/
reduction
and
UV/
vis
absorption
(
OPPTS
830.6314
and
7050)
and
for
the
Albemarle
98%
FI
concerning
oxidation/
reduction
(
OPPTS
830.6314).
All
pertinent
product
chemistry
data
requirements
have
been
satisfied
for
the
Great
Lakes
99.5%
FI.
Additional
data
are
required
for
the
remaining
Great
Lakes
MPs
as
follow:
(
i)
for
the
100%
T/
TGAI,
data
concerning
certified
limits,
oxidation/
reduction,
and
UV/
vis
absorption
(
OPPTS
830.1750,
6314,
and
7050);
(
ii)
for
the
98%
FI,
discussions/
data
concerning
formation
of
impurities,
certified
limits,
enforcement
methods,
and
oxidation/
reduction
(
OPPTS
830.1600,
1670,
1800,
and
6314);
and
(
iii)
for
the
67%
FI,
discussions/
data
concerning
formation
of
impurities,
enforcement
methods,
and
oxidation/
reduction
(
OPPTS
830.1670,
1800,
and
6314).
Provided
that
the
registrants
submit
the
data
required
in
the
attached
data
summary
tables
for
the
methyl
bromide
MPs,
and
either
certify
that
the
suppliers
of
beginning
materials
and
the
manufacturing
processes
have
not
changed
since
the
last
comprehensive
product
chemistry
reviews
or
submit
complete
updated
product
chemistry
data
packages,
the
Branch
has
no
objections
to
the
reregistration
of
methyl
bromide
with
respect
to

INTRODUCTION
Methyl
bromide
is
an
insecticide
and
antimicrobial
pesticide
registered
for
pre­
plant
soil
fumigation
and
post­
harvest
fumigation
of
numerous
raw
agricultural
commodities
and
processed
foods
and
feeds.
Methyl
bromide
is
registered
by
members
of
the
Methyl
Bromide
Industry
Panel
(
MBIP),
which
includes
Ameribrom,
Inc.,
Albemarle
Corp.,
Great
Lakes
Chemical
Co.,
and
Tri­
Cal,
Inc.
Pressurized
gas
(
PrG)
formulations
for
commodity
fumigation
are
marketed
under
the
trade
names
Meth­
O­
Gas
and
Metabrom.

REGULATORY
BACKGROUND
Methyl
bromide
is
a
List
A
reregistration
chemical.
It
was
the
subject
of
a
Registration
Standard
issued
3/
28/
86,
a
Guidance
Document
issued
8/
86,
and
a
Registration
Standard
Update
issued
6/
21/
91.
These
documents
summarized
the
regulatory
conclusions
on
the
available
residue
chemistry
data
and
specified
that
additional
data
were
required
for
reregistration
purposes.
Several
submissions
of
data
have
been
received
since
the
Registration
Standard
Update
was
issued.
The
information
contained
in
this
document
outlines
the
current
Residue
Chemistry
Science
Assessments
with
respect
to
the
reregistration
of
methyl
bromide.

Tolerances
for
residues
of
inorganic
bromides
in/
on
plant
raw
agricultural
commodities
(
RACs)
and
processed
foods
and
feeds
that
have
been
fumigated
with
methyl
bromide
have
been
established
under
40
CFR
§
180.123.
Tolerances
for
residues
of
inorganic
bromides
in/
on
plant
RACs
grown
in
soil
fumigated
with
combinations
of
chloropicrin,
methyl
bromide,
and
propargyl
bromide
have
been
established
under
40
CFR
§
180.199.

The
EPA
has
determined
that
soil
fumigation
uses
of
methyl
bromide
are
classified
as
non­
food
uses
(
S.
Irene,
1/
31/
97).
The
Agency
has
also
approved
the
replacement
of
inorganic
bromide
tolerances
with
tolerances
for
methyl
bromide
per
se,
as
supported
by
residue
chemistry
data
(
Letter
to
MBIP,
A.
Lindsay,
7/
7/
89).
Subsequently,
in
conjunction
with
acceptance
of
plant
metabolism
data,
HED
recommended
that
methyl
bromide
per
se
is
the
residue
to
be
regulated
(
DP
Barcode
D168913,
R.
Perfetti,
9/
24/
91).

The
Food
Quality
Protection
Act
(
FQPA)
of
1996
has
amended
and
strengthened
the
standard
for
establishing
tolerances
under
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA).
All
future
tolerance
petitions
as
well
as
reassessment
of
established
tolerances
must
meet
the
requirements
of
the
FFDCA
as
amended
by
the
FQPA.
OPP
may
require
additional
data
to
determine
if
the
terms
of
the
amended
statute
are
met.

regarding
the
reregistration
eligibility
of
methyl
bromide
food/
feed
uses
are
based
on
the
use
patterns
registered
by
members
of
the
MBIP.
When
end­
use
product
DCIs
are
developed
(
e.
g.,
at
issuance
of
the
RED),
RD
should
require
that
all
end­
use
product
labels
(
e.
g.,
MAI
labels,
SLNs,
and
products
subject
to
the
generic

exemption)
be
amended
such
that
they
are
consistent
with
the
basic
producers'
labels.

OPPTS

860.1300:
Nature
of
the
Residue
in
Plants
The
qualitative
nature
of
the
residue
in
plants
is
adequately
understood,
based
on
studies
in
which
the
commodities
maize,
potato,
alfalfa,
peanuts,
almonds,
oatmeal,
apples,
oranges,
and
wheat
were
fumigated
with
radioactive
methyl
bromide
at
a
rate
equivalent
to
~
2x
the
registered
rate.
Residues
consisted
of
methyl
bromide
and
naturally
occurring
compounds
such
as
methylated
amino
acids
and
nucleotides.
The
residue
of
concern
is
methyl
bromide
per
se.

HED
has
determined
that
the
pre­
plant
soil
fumigation
use
is
a
non­
food
use.
Treated
soil
must
3
be
fumigated
for
a
minimum
of
two
weeks
to
allow
sufficient
dissipation
of
residues;
excessive
residues
of
methyl
bromide
per
se
would
be
phytotoxic.
Minimal
methyl
bromide
residues
are
available
for
uptake
by
the
plant
at
the
end
of
the
soil
aeration
period.
Considering
the
highly
reactive
nature
of
methyl
bromide,
any
residues
taken
up
by
the
plant
would
be
converted
to
natural
constituents
by
the
time
of
plant
harvest.
Therefore,
tolerances
are
not
needed
to
support
the
pre­
plant
fumigation
use
of
methyl
bromide.

OPPTS
GLN
860.1300:
Nature
of
the
Residue
in
Livestock
Animal
metabolism
data
are
not
required
for
methyl
bromide.
Potential
feed
items
with
registered
post­
harvest
or
storage
fumigation
uses
include
stored
grain,
soybeans,
and
processed
animal
feeds.
The
maximum
tolerance
for
residues
in
any
of
these
is
10
ppm,
based
on
residues
24
hours
after
the
aeration
period
that
follows
fumigation.
The
transfer
of
detectable
residues
from
feed
items
to
meat,
milk
or
eggs,
is
not
expected,
and
is
a
Category

situation
under

§
180.6(

Analytical
Methods
The
head­
space
procedure
of
King
et
al.
for
determining
methyl
bromide
has
been
forwarded
to
FDA
for
inclusion
in
PAM
Vol.
II.
This
method
is
adequate
for
data
collection
and
would
be
suitable
for
tolerance
enforcement
on
plant
and
processed
food
commodities.
Analytical
methods
for
secondary
residues
of
methyl
bromide
in
livestock
commodities
are
not
required.

OPPTS

Multiresidue
Method
Testing
FDA
multiresidue
test
methods
are
not
applicable
to
methyl
bromide.
Protocols
A
and
B
are
not
applicable
to
monohalogenated
alkanes.
Although
methyl
bromide
would
be
detectable
in
protocol
C,
residues
would
like
not
be
recovered
through
any
of
the
extraction
techniques.

OPPTS

Storage
Stability
Data
Methyl
bromide
residues
decline
rapidly,
e.
g.,
30%
in
rice
stored
in
dry
ice
for
40
hours.
For
the
commodity
fumigation
residue
trials,
the
registrants
agreed
to
place
residue
samples
in
impermeable
containers
at
<
3.7
C
as
soon
as
possible.
HED
has
determined
that
storage
stability
data
are
not
required
unless
samples
are
or
have
been
stored
for
longer
than
12
hours.
Most
of
the
residue
data
used
to
reassess
tolerances
were
generated
from
samples
stored
for
12
hours
or
less.
For
some
samples
stored
for
longer
intervals,
results
were
compared
with
initial
analyses
obtained
after
shorter
periods;
the
results
were
comparable.
Therefore,
there
are
no
unresolved
storage
stability
issues
related
to
samples
used
for
tolerance
reassessment.

when
livestock
are
fed
raw

Therefore,

are
not

TOLERANCE
REASSESSMENT
SUMMARY
Tolerances
are
currently
established
for
residues
of
inorganic
bromides
(
calculated
as
Br)
in/
on
raw
and
processed
commodities
that
have
been
fumigated
with
the
antimicrobial
agent
and
insecticide
methyl
bromide
[
40
CFR
§
180.123].
The
Agency
has
approved
the
replacement
of
inorganic
bromide
tolerances
with
tolerances
for
methyl
bromide
per
se
as
supported
by
residue
chemistry
data
(
Letter
to
MBIP,
A.
Lindsay,
7/
7/
89).
In
conjunction
with
acceptance
of
plant
metabolism
data,
HED
subsequently
recommended
that
methyl
bromide
per
se
is
the
residue
to
be
regulated
(
DP
Barcode
D168913,
R.
Perfetti,
9/
24/
91).

The
reassessed
tolerances
under
40
CFR
§
180.123(
a)
should
be
defined
in
terms
of
residues
of
methyl
bromide
per
se
resulting
from
the
post­
harvest,
stored
commodity
fumigation
use
of
products
containing
methyl
bromide.
The
post­
harvest
designation
(
POST­
H)
following
each
commodity
listing
can
be
deleted.

Tolerances
have
also
been
established
for
residues
of
inorganic
bromides
(
calculated
as
Br)
in/
on
ginger
root
grown
in
soil
fumigated
with
methyl
bromide
[
40
CFR
§
180.123(
c)]
and
in
raw
agricultural
commodities
grown
in
soil
fumigated
with
chloropicrin,
methyl
bromide,
and
propargyl
bromide
[
40
CFR
§
180.199(
a­
c)].
The
Agency
has
determined
that
soil
fumigation
uses
are
classified
as
non­
food
uses
and
do
not
require
the
establishment
of
a
tolerance
or
exemption
from
a
tolerance
(
memorandum
to
S.
Johnson,
S.
Irene,
1/
31/
97).
Therefore,
the
tolerances
in
40
CFR
§
180.123(
c)
and
§
180.199(
a­
c)
should
be
revoked.

A
summary
of
the
methyl
bromide
tolerance
reassessment
for
the
above
commodities,
with
recommended
modifications
to
commodity
definitions,
is
presented
in
Table
C.

Tolerances
Listed
Under
40
CFR
§
180.123(
a)(
1):

Provided
that
the
requested
label
amendments
are
made,
sufficient
data
are
available
to
reassess
tolerances
for
residues
in/
on
all
commodities
with
uses
being
supported
by
the
MBIP.
The
available
commodity
fumigation
data
support
lowering
all
tolerance
levels,
with
the
exception
of
those
on
apples,
pears,
and
quinces.
The
available
data
indicate
that

DIETARY

ASSESSMENT
SUMMARY
For
reregistration
and
risk
assessment
purposes,
adequate
plant
metabolism
data
are
available.
Adequate
magnitude
of
the
residue
data
for
methyl
bromide
residues
are
also
available
for
all
the
registered
uses
the
MBIP
is
supporting.
Adequate
residue
data
are
also
available
for
all
processed
commodities.
Data
on
animal
metabolism
and
residues
in
animal
commodities
are
not
required.
A
reasonably
reliable
risk
assessment
for
the
uses
of
methyl
bromide
can
be
conducted
at
this
time
using
existing
and
reassessed
tolerances.

CODEX
HARMONIZATION
There
are
no
established
or
proposed
Codex
maximum
residue
limits
for
methyl
bromide;
therefore,
harmonization
of
U.
S.
tolerances
with
Codex
is
not
required.
