Abstract
This
document
presents
EPA's
decision
regarding
the
Food
Quality
Protection
Act
(
FQPA)
tolerance
reassessment
for
methyl
bromide
(
MeBr)
and
reregistration
eligibility
of
the
commodity
uses
of
the
active
ingredient
methyl
bromide.
The
Agency
has
conducted
human
health
and
environmental
fate
and
effects
risk
assessments
for
methyl
bromide
and
has
made
tolerance
reassessment
decisions
for
140
tolerances
related
to
all
registered
methyl
bromide
uses.
The
Agency
has
determined
that,
with
label
amendments
and
changes
as
specified
in
this
document,
there
is
a
reasonable
certainty
that
no
harm
will
result
to
the
general
U.
S.
population,
infants,
children,
or
other
population
subgroups,
from
methyl
bromide's
food
commodity
uses.

Generally,
registered
methyl
bromide
application/
fumigation
uses
fall
into
four
basic
categories
that
include:
(
1)
pre­
plant
soil
fumigations;
(
2)
structural,
industrial,
and
residential
uses;
(
3)
post­
harvest
food
commodity
uses;
and
(
4)
other
specialized
fumigations.
This
decision
document
covers
methyl
bromide
uses
that
have
accompanying
food
residue
tolerances
for
postharvest
fumigation
of
food
commodities
in
chambers
at
ports
or
specialized
structural
fumigations
at
food
processing
facilities.
Although
some
methyl
bromide
uses
such
as
fumigation
of
timber,
wood
products,
and
industrial
equipment
do
not
require
a
food
residue
tolerance,
the
Agency
has
included
them
in
this
reregistration
decision
since
they
are
performed
in
similar
facilities
and
were
assessed
with
a
similar
risk
assessment
methodology.
Hereafter,
these
methyl
bromide
uses
will
be
referred
to
as
"
methyl
bromide's
commodity
uses."

EPA
is
currently
assessing
risks
and
will
be
developing
risk
management
decisions
for
five
soil
fumigant
pesticides:
chloropicrin,
dazomet,
metam
sodium,
methyl
bromide,
and
a
new
active
ingredient,
iodomethane.
Risks
of
a
sixth
soil
fumigant,
1,3­
D
(
Telone),
are
also
being
analyzed
along
with
the
5
soil
fumigants
for
comparative
purposes
(
see
website
link
below);
its
risk
management
decision
was
completed
in
1998.
The
Agency
is
evaluating
these
soil
fumigants
concurrently
to
ensure
that
human
health
risk
assessment
approaches
are
consistent,
and
that
risk
tradeoffs
and
economic
outcomes
can
be
considered
appropriately
in
reaching
risk
management
decisions.
This
review
is
part
of
EPA's
program
to
ensure
that
all
pesticides
meet
current
health
and
safety
standards.
A
decision
on
the
reregistration
of
methyl
bromide's
non­
commodity
uses
that
do
not
have
food
tolerances
(
e.
g.,
structural
and
pre­
plant
soil
uses)
is
scheduled
to
be
completed
in
2007
with
the
other
soil
fumigants.
For
further
details
on
the
reregistration
of
the
soil
fumigants
see
http://
www.
epa.
gov/
oppsrrd1/
reregistration/
soil_
fumigants/.

The
completion
of
the
methyl
bromide
RED
for
food
commodity
uses
results
in
the
reassessment
of
128
existing
tolerances.
As
of
April
26,
2006,
the
Agency
considered
the
existing
12
tolerances
from
soil
fumigation
reassessed
(
see
April
26,
2006,
memo,
"
Completion
of
Tolerance
Reassessment
for
Inorganic
Bromides
Resulting
from
Soil
Treatment,"
from
D.
Edwards,
Special
Review
and
Reregistration
Division
Director
to
J.
Jones,
Office
of
Pesticides
Program
Director).
The
Agency's
reregistration
decision
on
methyl
bromide's
soil
uses
will
not
impact
this
RED
since
soil
uses
no
longer
have
related
food
tolerances
and
have
a
negligible
contribution
to
drinking
water
risks.

EPA
has
identified
potential
human
health
risks
of
concern
associated
with
the
currently
registered
commodity
uses
of
MeBr
from
acute
inhalation
exposure
to
workers
and
bystanders.
In
this
document
the
term
"
worker"
refers
to
persons
involved
in
applications
of
methyl
bromide.
Since
methyl
bromide
is
a
restricted­
use
pesticide
(
RUP),
fumigation
workers
must
be
certified
applicators,
or
be
working
under
the
direct
supervision
of
a
certified
applicator.
The
term
"
bystander"
in
this
document
refers
to
any
other
person
who
lives
or
works
in
the
vicinity
of
a
fumigation
site.
To
reduce
these
exposures
and
to
address
subsequent
risks
of
concern,
EPA
is
requiring
a
number
of
mitigation
measures
such
as
site­
specific
fumigant
management
plans
(
FMPs),
respiratory
protection,
buffer
zones,
posting
and
notification.
The
focus
of
the
Agency's
mitigation
measures
is
on
direct
acute
exposure
to
methyl
bromide
from
commodity
uses.
However,
the
Agency
has
concluded
that
many
of
these
measures,
combined
with
the
MeBr
phase­
out
mandated
by
the
Montreal
Protocol,
will
further
reduce
the
potential
health
effects
from
ozone
depletion
that
may
be
attributed
to
methyl
bromide's
commodity
uses,
such
as
skin
cancer.
The
Agency
has
determined
that
MeBr's
commodity
uses
are
eligible
for
reregistration
provided
that
the
risk
mitigation
measures
outlined
in
this
document
are
adopted
and
label
amendments
are
made
to
reflect
these
measures.

The
Agency
is
issuing
this
decision
document
for
MeBr,
as
announced
in
a
Notice
of
Availability
published
in
the
Federal
Register.
There
will
be
a
60­
day
public
comment
period
for
this
document
to
allow
stakeholders
the
opportunity
to
review
and
provide
comments
on
this
decision.

I.
Introduction
The
Federal
Insecticide,
Fungicide,
and
Rodenticide
Act
(
FIFRA)
was
amended
in
1988
to
accelerate
the
reregistration
of
products
with
active
ingredients
registered
prior
to
November
1,
1984.
The
amended
Act
calls
for
the
development
and
submission
of
data
to
support
the
reregistration
of
an
active
ingredient,
as
well
as
a
review
of
all
data
submitted
to
the
Environmental
Protection
Agency
(
hereafter
referred
to
as
EPA
or
the
Agency).
Reregistration
involves
a
thorough
review
of
the
scientific
database
underlying
a
pesticide's
registration.
The
purpose
of
the
Agency's
review
is
to
reassess
the
potential
risks
arising
from
the
currently
registered
uses
of
each
pesticide
chemical.
This
document
presents
EPA's
assessment
and
risk
management
decisions
for
methyl
bromide's
uses
in
enclosures,
chambers
and
structural
food
processing/
storage
facilities
(
hereafter
referred
to
as
commodity
uses)
to
determine
the
need
for
additional
data
on
health
and
environmental
effects,
and
to
determine
whether
or
not
these
uses
of
the
pesticide
meet
the
"
no
unreasonable
adverse
effects"
criteria
of
FIFRA
and
the
"
reasonable
certainty
of
no
harm"
criteria
of
the
Food
Quality
Protection
Act
(
FQPA).
Risks
summarized
in
this
document
are
those
that
result
only
from
the
commodity
uses
of
methyl
bromide.
However,
EPA
has
considered
potential
dietary
(
food
+
drinking
water)
risks
associated
with
all
methyl
bromide
uses,
including
pre­
plant
soil
uses.
As
a
result
of
this
review,
the
Agency
has
determined
that
all
products
registered
for
commodity
uses
containing
the
active
ingredient
methyl
bromide
are
eligible
for
reregistration
provided
that
the
risk
mitigation
measures
indicated
in
this
document
are
adopted.
10
The
completion
of
the
methyl
bromide
RED
for
commodity
uses
results
in
the
reassessment
of
all
140
existing
tolerances
(
i.
e.,
128
post­
harvest
uses
+
12
tolerances
from
preplant
soil
applications
that
were
already
re­
assessed
by
the
Agency).
A
decision
on
the
reregistration
of
methyl
bromide's
pre­
plant
soil
uses
will
be
completed
in
2007
with
the
other
soil
fumigants.
For
further
details
on
the
reregistration
of
the
soil
fumigants
see
http://
www.
epa.
gov/
oppsrrd1/
reregistration/
soil_
fumigants/.
The
Agency's
reregistration
decision
on
methyl
bromide's
soil
uses
will
not
impact
this
TRED/
RED
since
soil
uses
no
longer
have
related
food
tolerances
and
have
a
negligible
contribution
to
drinking
water.

The
Food
Quality
Protection
Act
(
FQPA)
requires
that,
when
considering
whether
to
establish,
modify,
or
revoke
a
tolerance,
the
Agency
consider
available
information
concerning
the
cumulative
effects
of
a
particular
pesticide's
residues
and
other
substances
that
have
a
common
mechanism
of
toxicity.
Unlike
other
pesticides
for
which
EPA
has
followed
a
cumulative
risk
approach
based
on
a
common
mechanism
of
toxicity,
EPA
has
not
made
a
common
mechanism
of
toxicity
finding
as
to
methyl
bromide,
and
methyl
bromide
does
not
appear
to
produce
a
toxic
metabolite
produced
by
other
substances.
Therefore,
for
the
purposes
of
reregistration,
EPA
has
not
assumed
that
methyl
bromide
shares
a
common
mechanism
of
toxicity
with
other
compounds.
For
information
regarding
EPA's
efforts
to
determine
which
chemicals
have
a
common
mechanism
of
toxicity,
see
the
policy
statements
released
by
EPA's
Office
of
Pesticide
Programs
concerning
common
mechanism
determinations
and

B.
Use
and
Usage
Profile
Pesticide
Type:
Methyl
bromide
is
a
broad­
spectrum
fumigant
chemical
that
can
be
used
as
an
acaricide,
antimicrobial,
fungicide,
herbicide,
insecticide,
nematicide,
and
vertebrate
control
agent.

Target
pests:
A
wide
range
of
pests
including
spiders,
mites,
fungi,
plants,
insects,
nematodes,
rodents,
and
snakes.

Use
patterns:
The
most
prevalent
use
pattern
is
as
a
soil
fumigant;
however,
it
is
also
used
as
a
structural
fumigant
and
for
post
harvest
treatment
of
commodities.

Formulations:
Pressurized
gas
(
PrG)
formulations
for
commodity
fumigation
are
marketed
under
the
trade
names
Meth­
O­
Gas
and
Metabrom.
All
methyl
bromide
products
are
classified
as
restricted
use
pesticides
(
RUP).
The
"
Restricted
Use"
classification
restricts
a
product,
or
its
uses,
to
use
by
certified
pesticide
applicators
or
those
working
under
the
direct
supervision
of
a
certified
applicator.

Methods
of
Application:
MeBr
gas
is
injected
into
an
enclosure,
chamber,
structure,
or
under
a
tarp
remotely
using
flexible
tubing
connected
to
PrG
tanks.

Application
Rates:
Application
rates
for
commodity
fumigations
can
range
from
1
to
20
lb
ai/
1000
ft3,
but
most
perishable
goods
with
established
food
tolerances
under
40
CFR
have
application
rates
in
the
range
of
1
to
4
lb
ai/
1000
ft3
(
e.
g.,
grapes).
Likewise,
structural
fumigation
application
rates
are
in
the
1
to
9
lb
ai/
1000
ft3
range.
12
Annual
Usage
in
the
U.
S.:
There
were
a
total
of
23
million
pounds
of
methyl
bromide
used
in
the
U.
S.
in
2004
with
3
million
pounds
used
on
commodities,
food
processing
facilities,
and
for
food
quarantine
uses,
and
20
million
pounds
used
on
all
other
sites.

There
are
currently
140
tolerances
related
to
registered
methyl
bromide
uses
in

Methyl
bromide's
commodity
uses
encompass
a
wide
range
of
enclosure
types
(
tarps,
vacuum
chambers,
tractor
trailers,
sea
vans,
drop­
down
enclosures,
flour
mills,
etc.),
enclosure
volumes
(
less
than
1,000
ft3
to
more
than
1,000,000
ft3),
and
locations
(
urban,
rural,
and
industrial).
Most
flour
mills
and
other
food
processing
plants
are
fumigated
no
more
than
once
per
year,
while
other
facilities
perform
fumigations
with
methyl
bromide
on
a
daily
basis
(

does
not
conduct
ecological

assessments
for
most
indoor
uses,
such
as
an
enclosed
container
or

treated
with
MeBr.
EPA
has
assessed
risks
associated
with
the
outdoor
soil
uses
of
MeBr
which
are
expected
to
result
in
higher
environmental
exposures.

Risk
Management,
Reregistration,
and
Tolerance
Reassessment
Decision
A.
Determination
of
Reregistration
Eligibility
Section
4(
g)(
2)(
A)
of
FIFRA
calls
for
the
Agency
to
determine,
after
submission
of
relevant
data
concerning
an
active
ingredient,
whether
or
not
products
containing
the
active
ingredient
are
eligible
for
reregistration.
The
Agency
has
previously
identified
and
required
the
submission
of
the
generic
(
i.
e.,
active
ingredient­
specific)
data
required
to
support
reregistration
of
products
for
commodity
fumigation
containing
methyl
bromide
as
an
active
ingredient.
The
Agency
has
completed
its
review
of
these
generic
data,
and
has
determined
that
the
data
are
sufficient
to
support
reregistration
of
products
containing
methyl
bromide
registered
for
commodity
uses
provided
the
label
changes
detailed
below
are
implemented.
Additional
data
are
required
to
confirm
this
determination.

The
Agency
has
completed
its
review
of
submitted
data
and
its
assessment
of
the
dietary,
residential,
and
occupational
risks
associated
with
the
commodity
uses
of
pesticide
products
containing
the
active
ingredient
methyl
bromide.
Based
on
these
data,
the
Agency
has
sufficient
information
on
the
human
health
and
ecological
effects
of
methyl
bromide
to
make
its
decision
as
part
of
the
reregistration
process
under
FIFRA,
as
amended
by
FQPA.
The
Agency
has
determined
that
products
containing
methyl
bromide
registered
for
commodity
fumigation
will
be
eligible
for
reregistration
provided
that
(
i)
required
product
specific
data
are
submitted,
(
ii)
the
14
risk
mitigation
measures
outlined
in
this
document
are
adopted,
and
(
iii)
label
amendments
are
made
to
reflect
these
measures.
Needed
label
changes
and
language
are
listed
in
Section
V.
Appendix
A
is
a
detailed
table
listing
all
methyl
bromide
uses
that
are
eligible
for
reregistration.
Appendix
B
identifies
generic
data
requirements
that
the
Agency
reviewed
as
part
of
its
determination
of
the
reregistration
eligibility
of
methyl
bromide's
commodity
uses,
and
lists
the
submitted
studies
the
Agency
found
acceptable.
Data
gaps
are
identified
as
either
outstanding
generic
data
requirements
that
have
not
been
satisfied
with
acceptable
data
or
additional
data
necessary
to
confirm
the
decision
presented
here.

Based
on
its
evaluation
of
methyl
bromide,
the
Agency
has
determined
that
methyl
bromide
products
for
commodity
fumigation,
unless
labeled
and
used
as
specified
in
this
document,
would
present
risks
inconsistent
with
FIFRA
and
FFDCA.
Accordingly,
should
a
registrant
fail
to
implement
any
of
the
risk
mitigation
measures
identified
in
this
document,
the
Agency
may
take
regulatory
action
to
address
the
risk
concerns
from
the
use
of
methyl
bromide.
If
all
changes
outlined
in
this
document
are
incorporated
into
the
product
labels,
then
all
current
risks
for
commodity
uses
of
methyl
bromide
commodity
fumigation
will
be
adequately
mitigated
for
the
purposes
of
this
determination
under
FIFRA.

B.
Public
Comments
and
Responses
Through
the
Agency's
use
of
a
6­
phase
public
participation
process,
EPA
worked
extensively
with
stakeholders
and
the
public
to
reach
the
regulatory
decisions
for
methyl
bromide's
commodity
uses.
The
6­
phase
process
included
two
60­
day
comment
periods.

the
first
comment
period
(
Phase
3),
the
Agency
solicited
and
received
comments

C.
Regulatory
Position
1.
Food
Quality
Protection
Act
Findings
a.
"
Risk
Cup"
Determination
As
part
of
the
FQPA
tolerance
reassessment
process,
EPA
assessed
the
risks
associated
with
methyl
bromide's
commodity
uses.
EPA
has
determined
that
risk
from
dietary
(
food
+
drinking
water)
exposure
is
within
its
own
"
risk
cup."
EPA
considered
aggregate
risks
for
methyl
bromide's
commodity
uses
for
exposures
through
dietary
and
residential
sources.
In
the
case
of
MeBr,
these
residential
exposures
are
to
any
person
who
lives
or
works
in
the
vicinity
of
a
fumigation
site.
The
Agency
has
determined
that
the
human
health
risks
from
these
combined
exposures
are
within
acceptable
levels
provided
the
mitigation
measures
outlined
in
this
document
are
adopted.
In
other
words,
EPA
has
concluded
that
the
tolerances
for
methyl
bromide
meet
FQPA
safety
standards
provided
the
mitigation
measures
outlined
in
this
document
are
adopted.
In
reaching
this
determination,
EPA
has
considered
the
available
information
on
the
special
sensitivity
of
infants
and
children,
as
well
as
aggregate
exposure
from
dietary
(
food
+
drinking
water)
and
residential
sources.

b.
Determination
of
Safety
to
U.
S.
Population
The
Agency
has
determined
that
the
140
established
tolerances
for
methyl
bromide,
with
amendments
and
changes
as
specified
in
this
document,
meet
the
safety
standards
under
the
FQPA
amendments
to
Section
408(
b)(
2)(
D)
of
the
FFDCA,
as
amended
by
FQPA,
and
that
there
is
a
reasonable
certainty
no
harm
will
result
to
the
general
population
or
any
subgroup
from
the
commodity
uses
of
methyl
bromide.
In
reaching
this
conclusion,
the
Agency
has
considered
all
available
information
on
the
toxicity,
use
practices,
and
the
environmental
behavior
of
methyl
bromide.
The
risks
from
food,
drinking
water,
and
residential
exposures
related
commodity
uses
do
not
exceed
the
Agency's
levels
of
concern,
with
the
risk
mitigation
specified
in
this
document.

2.
Endocrine
Disruptor
Effects
EPA
is
required
under
the
FFDCA,
as
amended
by
FQPA,
to
develop
a
screening
program
to
determine
whether
certain
substances
(
including
all
pesticide
active
and
other
ingredients)
"
may
have
an
effect
in
humans
that
is
similar
to
an
effect
produced
by
a
naturally
occurring
estrogen,
or
other
endocrine
effects
as
the
Administrator
may
designate."
Following
recommendations
of
its
Endocrine
Disruptor
Screening
and
Testing
Advisory
Committee
(
EDSTAC),
EPA
determined
that
there
was
a
scientific
basis
for
including,
as
part
of
the
program,
the
androgen
and
thyroid
hormone
systems,
in
addition
to
the
estrogen
hormone
16
system.
EPA
also
adopted
EDSTAC's
recommendation
that
EPA
include
evaluations
of
potential
effects
in
wildlife.
For
pesticides,
EPA
will
use
FIFRA
and,
to
the
extent
that
effects
in
wildlife
may
help
determine
whether
a
substance
may
have
an
effect
in
humans,
FFDCA
authority
to
require
the
wildlife
evaluations.
As
the
science
develops
and
resources
allow,
screening
for
additional
hormone
systems
may
be
added
to
the
Endocrine
Disruptor
Screening
Program
(
EDSP).

In
the
available
toxicity
studies
on
methyl
bromide,
there
was
no
evidence
of
endocrine
disruption
effects.
When
additional
appropriate
screening
and/
or
testing
protocols
being
considered
under
the
Agency's
EDSP
have
been
developed,
methyl
bromide
may
be
subjected
to
further
screening
and/
or
testing
to
better
characterize
effects
related
to
endocrine
disruption.

3.
Cumulative
Risks
Unlike
other
pesticides
for
which
EPA
has
followed
a
cumulative
risk
approach
based
on
a
common
mechanism
of
toxicity,
EPA
has
not
made
a
common
mechanism
of
toxicity
finding
as
to
methyl
bromide,
or
its
metabolites,
and
any
other
substances.
For
the
purposes
of
this
reregistration
decision,
therefore,
EPA
has
not
assumed
that
methyl
bromide
has
a
common
mechanism
of
toxicity
with
any
other
substances.

Pre­
Plant
Soil
Uses
There
are
12
tolerances
currently
established
for
residues
of
inorganic
bromide
resulting
from
methyl
bromide
soil
fumigation
(
40
CFR
180.199).
However,
EPA
has
classified
methyl
bromide
as
a
non­
food
use
pesticide
with
regard
to
its
soil
fumigant
uses
and
has
proposed
to
revoke
tolerances
for
soil
fumigation
related
inorganic
bromide.
The
Agency
stated
that
although
methyl
bromide
is
used
as
an
agricultural
pesticide,
it
is
considered
a
non­
food
use
chemical
for
soil
fumigation
uses
since
it
is
quickly
degraded
or
metabolized
in
the
soil,
and
subsequently
incorporated
into
natural
plant
constituents.
Methyl
bromide
is
also
emitted
to
the
atmosphere.
Residues
of
the
parent
compound
are
not
likely
to
be
found
in
foods
as
a
result
of
prior
treatment
of
fields.
While
residues
of
inorganic
bromide
may
be
present,
these
residues
are
indistinguishable
from
background
levels
of
inorganic
bromide
because
of
its
ubiquity
in
the
environment.
Therefore,
tolerances
are
not
required
for
soil
fumigant
uses
of
methyl
bromide,
and
tolerances
currently
established
for
residues
of
inorganic
bromide
resulting
from
methyl
bromide
soil
fumigation
have
been
proposed
for
revocation
by
the
Agency.
On
May
31,
2006,
EPA
issued
a
proposed
rule
to
revoke
the
twelve
tolerances
for
residues
of
inorganic
bromide
from
pre­
plant
soil
uses
(
71
FR
30845)
and
accepted
comments
for
60
days.
The
Agency
anticipates
issuing
a
final
rule
that
revokes
the
12
tolerances
in
August
2006,
after
the
Agency
has
completed
its
review
of
any
comments
received.

The
rationale
for
why
tolerances
are
not
needed
for
pre­
plant
soil
uses
is
provided
in
the
Agency's
February
8,
2006,
memo,
"

food
+
drinking
water)
Risk
The
Agency's
assessment
of
dietary
risk
from
food
plus
drinking
water
exposure
does
not
exceed
the
Agency's
level
of
concern.
Based
on
conservative
estimates
of
exposure
through
food
and
drinking
water,
dietary
risks
are
below
EPA's
level
of
concern
for
the
general
population
and
all
population
sub­
groups.
The
following
sections
describe
the
details
of
the
Agency's
food
and
water
exposure
estimates.

a.
Food
For
all
included
commodities,
the
acute
and
chronic
risks
do
not
exceed
the
Agency's
level
of
concern
for
the
general
U.
S.
population
and
all
population
subgroups.
The
acute
dietary
food
exposure
estimate
for
females
13­
49
years
old,
the
population
subgroup
with
the
highest
acute
risk,
is
at
2.4%
of
the
aPAD.
The
chronic
dietary
food
exposure
estimate
for
children
(
3
to
5
years
old),
the
most
highly
exposed
population
subgroup,
is
10%
of
the
cPAD.
The
acute
and
chronic
exposure
estimates
are
considered
to
be
very
conservative
since
it
was
assumed
that
100%
of
the
crops
were
treated
with
methyl
bromide.
This
is
likely
to
be
an
overestimate
of
the
percent
that
is
treated.
Therefore,
no
mitigation
is
necessary
to
address
the
risks
associated
with
food.

b.
Drinking
Water
The
Agency
typically
does
not
estimate
transport
of
pesticides
from
indoor
uses
such
as
methyl
bromide's
commodity
uses
to
surface
or
ground
water.
However
estimated
drinking
water
concentrations
(
EDWCs)
for
methyl
bromide's
soil
uses
were
developed
for
surface
and
ground
water
and
were
determined
to
be
below
EPA's
level
of
concern.

For
pre­
plant
soil
uses,
Florida
strawberries
resulted
in
the
highest
modeled
surface
water
concentration
of
357
µ
g/
L
for
acute
exposure,
and
1.0
µ
g/
L
for
the
chronic
exposure.
The
surface
water
EDWCs
are
considered
conservative,
upper­
bound
estimates
of
potential
concentrations
of
methyl
bromide
in
drinking
water,
and
EPA
believes
actual
concentrations
are
likely
to
be
much
lower.
This
is
due
to
several
factors
which
including:

 
Methyl
bromide
is
a
highly
volatile
compound
and
rapid
volatilization
from
soil
and
surface
water
is
expected
to
significantly
reduce
the
potential
concentrations
of
methyl
bromide
in
drinking
water.
24
 
Modeled
EDWCs
represent
potential
methyl
bromide
concentrations
in
raw
(
i.
e.,
untreated)
drinking
water.
EPA
expects
additional
volatilization
and
degradation
to
occur
between
the
reservoir
and
the
point
of
consumption.
 
The
EDWCs
are
based
on
applications
to
the
most
sensitive
surface
water/
crop
scenario
(
Florida
strawberries)
at
the
maximum
application
rate.
Further,
the
assessment
assumes
that
87%
of
a
watershed
is
planted
in
strawberries,
and
all
strawberries
in
the
watershed
are
treated
with
methyl
bromide
at
the
same
time.
 
The
PRZM/
EXAMS
models
have
limited
capability
to
capture
the
effect
of
using
tarps
to
contain
methyl
bromide,
which
is
the
standard
application
method
for
strawberries
in
Florida.
 
The
EDWCs
are
1­
in­
10
year
maximum
concentrations.

Groundwater
concentrations
were
not
estimated
for
methyl
bromide
because
the
model
used
for
estimating
groundwater
concentration,
SCIGROW,
has
limited
capability
to
model
vapor
phase
transport
of
methyl
bromide
to
groundwater.
Therefore,
EPA
used
monitoring
data
to
estimate
potential
exposure
to
MeBr
in
ground
water.
Based
on
a
database
of
pesticides
in
groundwater,
two
wells
in
California
(
out
of
20,429
wells
monitored
in
Florida,
California,
and
Hawaii)
had
detections
of
methyl
bromide
at
levels
from
2.5
­
6.4
µ
g/
L.
Given
the
concentrations
detected,
that
two
of
the
three
states
monitored
account
for
the
vast
majority
of
MeBr
use
in
the
U.
S.,
and
the
number
high
of
samples
with
non­
detects,
the
Agency
has
concluded
that
the
potential
exposure
to
methyl
bromide
in
ground
water
is
negligible.

The
Agency
has
determined
that
the
drinking
water
risk
from
methyl
bromide
from
commodity
uses
is
much
lower
than
for
soil
uses
and
the
potential
for
MeBr
exposure
through
drinking
water
is
negligible
since
essentially
all
of
the
methyl
bromide
applied
during
commodity
fumigation
is
emitted
to
the
atmosphere
and
does
not
readily
transport
to
drinking
water
sources.
For
further
details
on
the
Agency's
drinking
water
exposure
analysis,

the
June
6,
2005,
document
"
Environmental
Fate
and
Ecological
Risk
Assessment
for
the
Reregistration
of
Methyl
Bromide."

2.
Residential
Risks
The
human
health
risk
assessment
indicates
that
acute
inhalation
exposures
to
methyl
bromide
concentrations
of
1
ppm
or
greater
for
an
8­
hour
time
weighted
average
(
TWA)
pose
risks
of
concern
for
residential
bystanders.
The
1
ppm
8­
hour
TWA
is
based
on
the
8­
hour
TWA
human
equivalent
concentration
(
HEC)
of
30
ppm
from
a
developmental
rabbit
inhalation
study
where
the
fetal
effects
are
presumed
to
occur
after
one
exposure
and
an
uncertainty
factor
(
UF)
of
30
with
a
3x
for
interspecies
extrapolation
and
10x
for
intraspecies
variation
(
i.
e.
30
ppm/
30
UF
=
1
ppm).
For
further
details
on
the
HEC
and
UF,
see
the
Agency's
March
10,
2006,
memo,
"
Methyl
Bromide:
Phase
5
Health
Effects
Division
(
HED)
Human
Health
Risk
Assessment
for
Commodity
Uses.
PC
Code:
053201,
DP
Barcode:
D304623."
In
the
case
of
MeBr,
these
residential
bystander
exposures
are
to
any
person
who
lives
or
works
in
the
vicinity
of
a
fumigation
site.
The
mitigation
measures
described
below
are
expected
to
ensure
that
acute
exposures
do
not
exceed
this
level.
The
Agency
has
concluded
that
measures
to
ensure
that
25
acute
risks
are
below
EPA's
level
of
concern
will
also
mitigate
risks
for
other
exposure
durations
(
i.
e.
short­
term,
intermediate­
term,
and
chronic)
to
levels
below
EPA's
level
of
concern.
In
addition,
many
of
the
mitigation
measures
are
expected
to
indirectly
reduce
the
amount
of
methyl
bromide
used
or
emitted
into
the
atmosphere
and
therefore
will
reduce
the
potential
risks
associated
with
stratospheric
ozone
depletion
resulting
from
methyl
bromide
commodity
uses.

The
Agency
believes
that
a
comprehensive
approach
that
requires
mitigation
measures
such
as
fumigation
management
plans
(
FMPs),
buffer
zones,
air
monitoring,
posting
and
notification,
and
record
keeping,
will
ensure
that
acute
risks
from
inhalation
exposure
to
both
workers
involved
in
the
fumigation
process
and
bystanders
in
areas
around
enclosures
do
not
exceed
EPA's
level
of
concern.
California
established
permit
conditions
for
methyl
bromide
commodity
fumigations
in
1994
that
included
the
use
of
buffer
zones
and
other
measures
that
are
similar
to
what
EPA
is
now
requiring.
A
recent
analysis
conducted
by
the
California
Department
of
Pesticide
Regulation
(
CDPR)
indicates
a
major
reduction
of
injury
and
illnesses
associated
with
methyl
bromide
commodity
fumigations
since
permits
were
required.
CDPR
attributes
this
reduction
in
large
part
to
the
conditions
under
which
permits
are
granted.
Further
details
regarding
California's
permit
conditions
for
MeBr
commodity
fumigations
are
available
on
CDPR's
website
(

cdpr.
ca.

htm).

Quarantine
fumigations
supervised
by
USDA's
Animal
and
Plant
Health
Inspection
Service
(
APHIS)
account
for
a
large
percentage
of
the
total
commodity
fumigations
performed
in
the
US.
The
EPA
has
worked
closely
with
APHIS
in
the
development
of
the
Agency's
risk
assessment
and
mitigation
measures.
Many
of
the
fundamental
elements
(
e.
g.,
FMPs,
buffer
zones,
air
monitoring,
record
keeping,
etc.)
of
the
mitigation
measures
that
are
being
required
by
this
decision
document
for
commodity
fumigations
are
already
required
and
enforced
by
on­
site
APHIS
Plant
Protection
and
Quarantine
Officers
(
PPQOs).

The
mitigation
measures
detailed
below
will
require
the
applicator/
fumigator
to
develop
a
fumigation
management
plan
(
FMP),
or
ensure
one
exists
for
each
specific
site
that
will
be
fumigated
with
methyl
bromide.
Required
elements
of
the
FMP
are
listed
below
in
Section
E.
In
developing
this
plan,
the
fumigator
will
determine
the
distance,
called
a
buffer
zone,
which
will
protect
workers
and
bystanders
from
exposure
to
methyl
bromide
that
could
exceed
the
Agency's
level
of
concern.
The
Agency
will
provide
guidance
in
the
form
of
buffer
zone
lookup
tables
to
enable
fumigators
to
protect
workers
and
bystanders.
These
tables
will
be
available
on
the
Agency
internet
website
along
with
an
Agency
methyl
bromide
commodity
fumigation
reference
manual.
If,
based
on
the
current
site
conditions
(
e.
g.,
local
exhaust
ventilation
systems,
enclosure/
chamber/
structure
retention
rates,
size
of
treatment
area,
etc.),
the
size
of
the
buffer
zone
listed
in
the
Agency's
look­
up­
tables
is
not
feasible
due
to
encroachment
of
occupied
areas/
structures,
the
fumigator
can
opt
to
modify
the
fumigation
parameters
or
alter
the
site
conditions
so
that
a
smaller
buffer
zone
can
be
used.
Examples
of
alternative
approaches
include
but
are
not
limited
to:

 
Reducing
application
rates
26
 
Extending
treatment
time
and
allowing
methyl
bromide
concentrations
to
slowly
decline
before
starting
active
aeration
(
e.
g.,
in
California,
large
mills
are
extending
treatment
time
from
24
to
48
hours
to
attain
smaller
buffer
zones)
 
Subdividing
treatment
areas
 
Installing
or
modifying
local
exhaust
ventilation
systems
(
e.
g.,
location/
height
of
exhaust
outlet)
 
Improving
the
tightness
or
retention
capacity
of
the
enclosure/
chamber/
structure
 
Empirically
deriving
retention
or
loss
rates
of
the
enclosure/
chamber/
structure
(
e.
g.,
CDPR
uses
a
one­
time
procedure
where
the
low
rate
of
1
lb
ai/
1000
ft3
rate
is
used
with
an
empty
chamber
to
determine
loss
rate)
 
Installing
capture
recovery
or
destructive
systems
(
e.
g.,
scrubbers)

If
these
options
do
not
result
in
feasible
buffer
zones
for
the
site,
there
are
additional
alternatives
detailed
below
that
will
give
fumigators
more
flexibility
but
still
ensure
that
methyl
bromide
levels
do
not
exceed
the
Agency's
level
of
concern
(
e.
g.,
buffers
based
on
site­
specific
modeling
and
air
monitoring,
with
limited
exceptions
for
traffic
and
other
areas
provided
certain
conditions
are
met).
Although
the
Agency
believes
the
approach
outlined
here
offers
substantial
flexibility
for
site­
specific
solutions
that
are
protective
of
workers
and
bystanders,
it
also
recognizes
that
there
will
likely
be
some
commodity
fumigation
sites
where
MeBr
will
no
longer
be
practical
to
use.
The
mitigation
measures
that
the
Agency
is
requiring
to
protect
bystanders
are
described
further
in
Section
E
below.

3.
Aggregate
Risk
a.
Acute
For
methyl
bromide,
acute
dietary
risks
are
well
below
EPA's
level
of
concern
for
the
general
U.
S.
population
and
all
population
subgroups
based
on
conservative
data
and
assumptions
as
described
above
in
the
dietary
risk
section
of
this
document.

Because
the
acute
dietary
and
acute
inhalation
endpoints
for
methyl
bromide
are
based
on
a
common
effect,
it
would
be
appropriate
to
aggregate
dietary
exposures
(
using
average,
or
"
chronic",
dietary
exposure
values)
with
acute
inhalation
exposures.
However,
because
the
dietary
contribution
to
acute
aggregate
risk
is
negligible,
EPA
has
determined
that
the
mitigation
measures
EPA
is
requiring
to
protect
residential
bystanders
will
ensure
that
acute
aggregate
risks
do
not
exceed
EPA's
level
of
concern.
Therefore
no
additional
mitigation
is
necessary
to
address
acute
aggregate
risk.

b.
Short­,
Intermediate­
Term,
and
Chronic
Aggregate
Risk
EPA
did
not
aggregate
short­,
intermediate­
term,
or
chronic
dietary
and
inhalation
exposures
to
methyl
bromide
because
endpoints
for
dietary
and
inhalation
exposures
for
these
durations
are
not
based
on
common
toxicological
effects.
27
4.
Worker
Risks
The
human
health
risk
assessment
indicates
that
acute
inhalation
exposures
to
methyl
bromide
concentrations
of
1
ppm
or
greater
for
an
8­
hour
time
weighted
average
(
TWA)
pose
risks
of
concern
for
workers.
The
mitigation
measures
described
below
in
Section
E
are
designed
to
ensure
that
acute
exposures
for
workers
do
not
exceed
this
level.
These
measures
include
requiring
respiratory
protection
for
methyl
bromide
air
concentration
levels
of
greater
than
1
ppm
for
an
8­
hr
TWA
and
establishing
procedures
for
determining
when
the
use
of
respiratory
protection
may
be
discontinued.
The
mitigation
measures
also
specify
air
monitoring
requirements
to
document
the
measurement
of
worker's
potential
methyl
bromide
inhalation
exposure
throughout
the
fumigation
process.
The
Agency
is
also
requiring
that
fumigators
ensure
that
site­
specific
management
plans
that
include
the
elements
described
in
detail
in
Section
E
below
are
in
place
before
initiating
fumigation.
EPA
has
determined
that
these
requirements
will
protect
fumigation
workers
as
well
as
other
onsite
workers
(
e.
g.,
forklift
operators
and
other
occupational
bystanders).

5.
Stratospheric
Ozone
Depletion
Risks
The
focus
of
the
Agency's
mitigation
measures
as
specified
in
section
E
below
is
to
ensure
protection
from
direct
acute
exposure
to
methyl
bromide
from
commodity
uses.
The
Agency
concludes
that
many
of
these
measures
(
e.
g.,
those
that
reduce
the
total
amount
used
or
use
MeBr
capture/
destruction
systems)
combined
with
the
methyl
bromide
phase­
out
under
the
Montreal
Protocol
(
i.
e.
all
commodity
uses
except
for
pre­
shipment
and
quarantine
uses
which
are
exempt)
will
further
reduce
the
potential
health
effects
from
ozone
depletion,
such
as
skin
cancer,
which
may
result
from
methyl
bromide's
commodity
uses.

6.
Ecological
Risk
The
Agency
does
not
perform
ecological
risk
assessments
for
most
indoor
uses,
such
as
an
enclosed
container
or
perimeter
treated
with
MeBr.
Ecological
risks
from
outdoor
soil
fumigation
uses
of
MeBr
will
be
addressed
in
the
reregistration
decisions
for
those
uses
in
2007.

E.
Residential
Bystander
and
Occupational
Risk
Mitigation
The
following
describes
the
rationale
for
the
risk
management
decisions
for
bystander
and
worker
risks
associated
with
methyl
bromide's
commodity
uses.
Public
comments
and
input
from
key
stakeholders
were
considered
in
making
these
decisions.
Where
labeling
revisions
are
warranted,
specific
language
is
set
forth
in
summary
tables
of
Section
V
of
this
document.
It
is
the
Agency's
goal
to
ensure
exposures
are
below
the
Agency's
level
of
concern
but
allow
flexibility
for
local,
site­
specific
approaches,
where
feasible.

1.
Site­
Specific
Fumigation
Management
Plan
(
FMP)
28
Prior
to
fumigating
commodities,
a
site­
specific
FMP
must
be
developed
and
followed.
The
purpose
of
the
FMP
is
to
ensure
the
safety
of
the
fumigators,
other
on­
site
employees,
the
surrounding
community,
and
the
environment.
It
is
also
designed
to
ensure
an
effective
fumigation
that
complies
with
label
requirements.
The
responsible
party
(
i.
e.,
the
person
supervising
the
fumigation)
is
responsible
for
ensuring
FMPs
are
up­
to­
date
and
accurately
reflect
the
site
and
current
circumstances
for
fumigation
before
it
takes
place,
and
that
the
FMPs
are
followed.
The
Agency
will
provide
detailed
guidance
for
FMPs
including
a
list
of
minimum
elements
that
site­
specific
plans
must
address.
This
guidance
will
be
incorporated
in
a
methyl
bromide
commodity
fumigation
reference
manual
that
will
be
available
on
the
Agency's
internet
website.
Product
labels
will
require
FMPs
be
developed
based
on
the
Agency
manual.
Elements
that
are
not
applicable
to
a
given
site
may
be
so
noted
in
the
site­
specific
plans.
The
following
are
elements
that
must
be
included
in
all
FMPs
unless
not
relevant
to
a
specific
site:

The
use
of
a
comprehensive
FMP
will
result
in
careful
planning
of
all
aspects
of
the
fumigation
process.
While
FMPs
alone
will
not
eliminate
risk,
they
constitute
a
written
record
that
provides
specific
logistical,
performance,
and
contact
information
to
help
characterize
the
site
and
the
fumigation
process.

The
responsible
party
(
i.
e.
the
person
supervising
the
fumigation)
must
certify
in
writing
that
he/
she
has
reviewed
the
FMP
and
that
it
addresses
all
elements
required
by
product
labels
and
the
Agency
methyl
bromide
commodity
fumigation
reference
manual,
and
that
all
decisions
on
the
treatment/
aeration
processes,
buffer
zones,
and
PPE
are
appropriate
and
protective.
States
or
local
governments
may
opt
to
require
third­
party
certification
(
e.
g.,
county
agricultural
commissioners,
state
pesticide
enforcement
officials,
certified
industrial
hygienists,
or
certified
safety
professionals).
In
that
case,
where
fumigations
are
supervised
by
a
federal
authority
such
as
APHIS,
the
federal
agency
may
certify
the
FMP.
The
responsible
party
must
contact
the
applicable
State
lead
agency
to
determine
the
certification
requirements
for
that
state.

For
emergency
fumigations
that
must
be
performed
with
limited
advance
notice,
(
e.
g.,
quarantine
fumigation
of
a
ship
or
other
container)
generic
plans
that
are
not­
site
specific
may
be
developed,
completed,
and
certified
as
needed.

a.
Buffer
Zones
This
decision
requires
that
fumigators
establish
a
buffer
zone
during
the
treatment
and
aeration
periods
which
the
responsible
party
has
determined
will
protect
bystanders
and
workers
from
risks
posed
by
MeBr.
EPA
is
preparing
guidance
to
assist
fumigators
in
making
these
decisions.
Only
persons
supervising
or
performing
fumigation
activities
are
permitted
within
the
buffer
zones.
All
other
people
including
workers,
nearby
residents,
and
other
bystanders
must
be
excluded
from
this
zone
except
for
as
provided
below.
The
buffer
zone
established
for
the
treatment
period
must
be
maintained
from
the
time
MeBr
is
introduced
until
the
aeration
period
begins.
An
aeration
buffer
zone
must
then
be
established
and
maintained
until
the
methyl
bromide
concentration
being
exhausted
from
the
enclosure
is
less
than
5
ppm
(
see
below
for
minimum
aeration
times).
This
5
ppm
level
for
aeration
is
currently
required
by
the
product
label.
It
should
be
noted
that
the
buffer
zone
during
the
aeration
period
in
most
fumigations
will
last
only
a
portion
of
the
aeration
period
(
e.
g.,
the
air
being
exhausted
from
the
treated
area
is
less
than
5
ppm
but
aeration
is
still
being
done
until
air
concentration
within
commodity
reaches
5
ppm
or
less).

The
Agency's
risk
assessment
provides
modeled
distances
for
treatment
and
aeration
periods
for
a
wide
range
of
sites
at
which
acute
exposures
have
the
potential
to
exceed
the
Agency's
level
of
concern
of
1
ppm
for
an
8­
hour
TWA
if
bystanders
are
present.
The
Agency
modeled
potential
acute
bystander
exposure
to
methyl
bromide
with
a
distributional
approach
using
PERFUM.
The
PERFUM
model
(
V2.1.2)
is
available
at
30
http://
www.
sciences.
com/
perfum/
index.
html
and
will
eventually
be
placed
on
the
Agency's
website
at
http://
www.
epa.
gov/
opphed01/
models/
fumigant/.
The
PERFUM
modeling
framework
was
subjected
to
a
Scientific
Advisory
Panel
(
SAP)
review
in
2004.
Please
refer
to
the
SAP
background
documents
and
the
SAP
report
(
http://
www.
epa.
gov/
scipoly/
sap/
2004/
index.
htm).
Additional
characterization
of
the
Agency's
use
of
PERFUM
in
estimating
acute
bystander
exposure
to
methyl
bromide
is
also
included
in
section
6.2
of
the
Agency
risk
assessment
document.

The
PERFUM
model
provides
two
types
of
results
that
include
the
maximum
buffer
distance
and
the
whole
field
buffer
distance.
Each
is
reported
as
a
distribution
of
distances.
The
whole
field
distance
outputs
represent
the
entire
range
of
potential
exposures,
whereas
maximum
buffer
distance
outputs
represent
a
subset
of
the
highest
daily
exposure
levels
that
were
calculated.
This
approach
provides
more
resolution
at
the
highest
levels
of
exposures.
In
other
words,
a
given
percentile
of
the
whole
field
distance
results
is
essentially
equivalent
to
a
corresponding
percentile
of
maximum
buffer
distance
results
(
i.
e.,
`
x'
percentile
whole
field
distance
results
=
`
y'
percentile
maximum
buffer
distance
results).
The
Agency
considered
which
PERFUM
output
results
would
adequately
ensure
bystander's
acute
exposures
do
not
exceed
1
ppm
for
an
8­
hour
TWA.

The
Agency
is
basing
its
buffer
zone
distances
for
MeBr's
commodity
uses
on
99th
percentile
whole
field
distance
outputs
from
PERFUM
model
results.
These
results
represent
the
distances
within
which
all
bystanders
must
be
excluded
to
ensure
that
their
acute
exposure
to
methyl
bromide
does
not
exceed
the
Agency's
level
of
concern.
EPA
believes
that
requiring
buffers
at
these
distances
combined
with
other
mitigation
measures
described
in
this
document
will
ensure
that
exposures
will
not
exceed
the
Agency's
level
of
concern.
Furthermore,
an
analysis
by
the
Agency
has
determined
that
the
distances
for
scenarios
modeled
using
the
99th
percentile
whole
field
distance
outputs
are
in
many
cases
is
similar
to
the
distances
currently
required
by
California's
permit
conditions
for
MeBr
commodity
fumigations.
As
previously
noted
above,
the
EPA
believes
that
establishing
buffers
zones
along
with
other
elements
of
California's
permitting
system
have
been
very
effective
in
reducing
methyl
bromide
exposures.

It
should
be
noted
that
the
Agency
has
modeled
ground
level
local
exhaust
ventilation
(
i.
e.,
the
PPQ
method),
while
CDPR
prohibits
this
practice.
The
Agency
will
allow
the
use
of
this
method
in
states
that
do
not
prohibit
it
provided
all
mitigation
measures
described
in
this
document
and
on
product
labels
are
followed.
The
discharge
location
of
the
ground
level
exhaust
ventilation
must
be
at
least
25
feet
from
the
enclosure
(
and
any
building
that
houses
the
enclosure).

1)
Buffer
Zones
Based
on
Agency
Look­
Up­
Tables
The
Agency
will
provide
information
in
the
form
of
look­
up
tables
for
commodity
fumigators
to
follow
to
ensure
that
workers
and
bystanders
are
protected.
These
tables
will
be
available
on
the
Agency's
internet
website
along
with
a
methyl
bromide
commodity
fumigation
reference
manual
for
a
full
range
of
application
rates,
loss
rates,
local
ventilation
systems,
and
31
enclosure/
chamber/
structure
volumes
which
can
be
determined
and
which
must
be
established
for
each
site.
Distinct
buffer
zones
will
be
required
during
the
treatment
and
aeration
periods
and
once
the
aeration
period
is
completed
the
buffer
zones
may
be
discontinued.
The
Agency
has
determined
that
establishment
of
these
buffers
will
ensure
that
bystander
exposure
to
methyl
bromide
will
not
exceed
the
Agency's
level
of
concern.
Only
authorized
persons
with
respiratory
protection
(
as
specified
in
respiratory
protection
section
below)
may
be
permitted
within
the
buffer
zones.

2)
Buffer
Zones
Based
on
Alternate
Methods
Buffer
zones
that
are
more
or
less
than
those
listed
in
the
Agency's
look­
up
tables
may
be
established
based
on
site­
specific
modeling
(
using
site­
specific
data
such
as
weather,
flux
rates,
empirically
derived
or
measured
retention
rates,
etc.).
The
Agency
recognizes
that
it
is
not
practical
or
feasible
to
capture
every
possible
site
scenario
in
look­
up
tables.
Therefore
buffer
zones
based
on
site­
specific
enclosure/
chamber/
structural
volumes
or
local
exhaust
ventilation
(
LEV)
system
parameters
may
also
be
modeled
for
individual
sites.
Only
models
specified
in
the
Agency's
methyl
bromide
commodity
fumigation
reference
manual
may
be
used
to
determine
buffer
zones.

Since
the
number
of
samples
needed
to
adequately
measure
maximum
downwind
concentration
is
possible
but
impractical,
air­
monitoring
data
alone
will
likely
not
be
sufficient
to
reduce
required
buffer
zones.
However,
the
Agency
will
allow
buffer
zone
distances
to
be
determined
based
on
site­
specific
air
monitoring
that
is
done
in
accordance
with
criteria
that
will
be
specified
in
the
Agency
methyl
bromide
commodity
fumigation
manual.

Air
monitoring
and
modeling
for
methyl
bromide
destruction
or
capturing
devices
such
as
scrubbers
may
also
be
used
to
determine
the
use
of
smaller
buffer
zones
than
those
listed
in
the
Agency's
look­
up
tables.
While
this
mitigation
method
may
not
yet
be
currently
economically
feasible
for
larger
sites,
it
is
one
of
the
few
options
that
directly
reduce
the
total
methyl
bromide
released
and
potential
ozone
depletion.

3)
Minimum
Buffer
Zones
While
modeling
results
predict
no
risk
concern
for
locations
immediately
adjacent
to
the
discharge
location
for
some
scenarios,
the
Agency
believes
that
best
management
practices
warrant
a
minimum
buffer
for
all
sites.
Therefore,
the
responsible
party
must
determine
an
appropriate
minimum
buffer
zone
based
on
site­
specific
conditions.
For
example,
APHIS
may
decide
to
maintain
their
currently
required
buffers
of
30
ft
and
200
ft
buffers
for
treatment
and
aeration
periods,
respectively,
as
a
minimum
buffer
zone.
However,
EPA
believes
the
minimum
buffers
during
treatment
and
aeration
periods
should
never
be
less
than
10
feet
during
treatment
and
aeration
periods.
These
minimum
distances
are
based
on
the
current
requirements
used
by
California
for
commodity
fumigation.

4)
Exceptions
32
Occupied
Structures
Exceptions
from
buffer
zones
for
occupied
structures
that
are
within
the
buffer
zones
may
be
made
in
a
FMP
if
air
monitoring
of
methyl
bromide
concentrations
within
the
occupied
structure
and
around
the
perimeter
of
the
fumigated
enclosure
during
treatment
and
aeration
periods
are
less
than
a
ceiling
limit
of
5
ppm
or
an
8­
hour
TWA
of
1
ppm.
The
Agency's
methyl
bromide
commodity
fumigation
reference
manual
will
provide
guidance
regarding
air
monitoring
methods
for
these
exceptions.
Exemptions
may
not
be
used
for
sensitive
sites
(
such
as
homes,
schools,
hospitals,
employee
housing
centers)
or
buildings
that
share
a
wall
with
an
enclosure
being
fumigated.
FMPs
must
establish
emergency
procedures
to
be
followed
in
the
event
air
concentrations
exceed
a
ceiling
limit
of
5
ppm
or
an
8­
hour
TWA
of
1
ppm
at
these
locations
(
e.
g.,
immediate
evacuation
or
use
of
respirators
for
workers).
The
specified
buffer
zone
will
be
required
for
all
other
areas.
Prior
to
conducting
fumigations,
the
responsible
party
must
obtain
written
acknowledgement
from
occupants
of
any
structures
that
are
exempted
from
buffer
zones
that
the
occupants
have
received
information
on
the
hazards
of
methyl
bromide
and
understand
the
emergency
procedures
specified
in
the
FMP.

Non­
Occupied
Structures
Exceptions
from
buffer
zones
for
structures
that
have
been
evacuated
that
are
within
the
buffer
zone
may
be
made
in
the
FMP.
Steps
must
be
specified
that
will
ensure
that
occupants
do
not
reenter
the
structure
until
treatment
and
aeration
periods
are
completed
and
that
air
concentrations
within
the
structure
do
not
exceed
1
ppm
for
an
8­
hour
TWA
when
occupants
reenter
the
structure.

Transit
Limited
transit
(
e.
g.,
use
of
roads)
for
brief
durations
within
the
buffer
zone
may
occur
be
if
unavoidable.

b.
Posting
and
Notification
Workers
who
handle
treated
commodities
after
they
are
transported
from
fumigation
sites
have
a
right­
to­
know
the
potential
risks
related
to
the
handling
of
the
treated
commodities.
This
is
especially
a
concern
for
workers
who
handle
treated
commodities
from
which
the
methyl
bromide
desorption
rate
is
slow
(
e.
g.,
walnuts
and
timber).
The
fumigator
must
provide
these
workers
access
to
the
material
safety
data
sheet
(
MSDS)
for
the
methyl
bromide
end­
use
product
before
workers
come
in
contact
with
the
treated
commodities.
In
addition,
the
exterior
of
containers/
packaging
of
all
treated
commodities
must
be
clearly
identified
as
having
been
fumigated
with
methyl
bromide
and
aerated
in
accordance
with
EPA
labels
before
leaving
fumigation
facilities.
Fumigators
must
also
comply
with
applicable
Department
of
Transportation
and
any
other
federal,
state,
and
local
requirements
for
placarding
vehicles
leaving
fumigation
sites.
33
The
community
living
or
working
in
close
proximity
to
commodity
fumigation
sites
must
have
accesses
to
information
on
the
nature
of
applications
taking
place
and
potential
hazrads
that
nearby
fumigations
may
pose.
Specifically,
fumigators
must
ensure
that
all
residents
and
businesses
that
own
or
occupy
properties
adjacent
to
sites
where
commodity
fumigations
with
MeBr
are
taking
place
(
and
those
located
adjacent
to
buffer
zones
specified
in
the
FMP)
have
been
notified
and
provided
with
information
on
how
the
community
can
access
FMPs
for
that
site.
Once
an
initial
notification
is
completed,
notification
must
occur
annually,
or
within
30
days
after
a
change
in
the
FMP.
Notification
may
done
via
mail,
newspaper,
radio,
television,
posting
at
public
sites
(
e.
g.,
library,
court
house,
post
office)
or
other
methods
which
the
responsible
party
has
determined
is
likely
to
ensure
adjacent
residents
and
businesses
have
access
to
the
required
information.

The
posting
and
notification
requirements
for
the
community
and
workers
will
help
ensure
compliance
with
mitigation
measures
required
by
this
decision
and
the
product
label.
Furthermore,
EPA
believes
that
when
workers
and
members
of
the
community
are
well
informed,
compliance
with
mitigation
measures
is
more
likely
to
be
successful
and
protective.

c.
Record
Keeping
1)
Fumigation
Sites
All
monitoring
results,
application
dates,
and
current
FMPs
must
be
kept
on­
site
and
be
made
readily
available
to
local/
state/
federal
enforcement
personnel
and
all
workers,
and
be
provided
upon
request
to
any
interested
party
in
the
community.
FMPs
must
be
kept
and
be
available
for
at
least
2
years
from
the
date
of
fumigations.
Mobile
or
non­
fixed
sites
(
e.
g.,
ship
holds
or
sites
with
no
fixed
buildings
or
structures
after
fumigation
is
completed)
are
required
to
keep
records
on­
site
only
during
the
entire
fumigation
process
(
i.
e.,
pre­
treatment,
treatment,
and
aeration
periods).
Site
records
may
be
maintained
and
made
available
to
the
public
using
the
Internet
or
other
methods.
On­
sites
records
will
be
used
by
local,
state,
and
federal
enforcement
staff
to
verify
compliance
with
EPA
labels.

2)
Fumigators
Responsible
parties
supervising
fumigations
must
also
maintain
records
of
monitoring
results
and
application
dates
for
all
sites
where
they
have
conducted
fumigations
for
at
least
two
years
from
the
date
of
fumigations.
In
addition,
they
must
also
maintain
FMPs
for
each
site
fumigated
for
at
least
two
years
from
the
date
of
fumigations.
Fumigators
must
also
comply
with
any
local
or
State
record
keeping
requirements.

2.
Respiratory
Protection
for
Fumigation
Workers
and
Other
On­
site
Workers
Respiratory
protection
will
be
required
for
anyone
entering
any
area
where
methyl
bromide
concentrations
are
greater
than
1
ppm
for
an
8­
hour

The
EPA
has
decided
that
the
use
of
3M
air
purifying
respirators
(
APRs)
equipped
with
3M
Model
60928
Organic
Vapor/
Acid
Gas/
P100
cartridges
may
be
used
for
concentrations
up
to
5
ppm,
and
not
for
more
than
one
work
shift
per
day
(
and
any
MSHA­
NIOSH
certified
cartridge
for
MeBr
that
becomes
available).
Respirator
APR­
cartridge
combinations
for
other
manufacturers
will
also
be
considered
by
the
Agency
provided
written
certification
of
their
efficiency
against
methyl
bromide
is
provided.
CDPR
currently
allows
the
use
of
the
3M
60928
Cartridge/
Filter
for
methyl
bromide
concentrations
up
to
5
ppm
for
commodity
fumigations.
The
current
requirement
that
aeration
of
all
treated
commodities
continue
until
methyl
bromide
concentrations
(
within
the
treated
commodity)
are
5
ppm
or
less
will
not
be
changed.
For
methyl
bromide
air
concentrations
greater
than
5
ppm,
supplied
air
(
SA)
respirators
or
self
contained
breathing
apparatus
(
SCBA)
must
be
worn
by
all
fumigation
workers
and
other
on­
site
personnel.

Manufacturers
of
direct­
read
instruments
commonly
used
during
fumigations
specify
a
limit
of
detection
as
low
as
0.2
ppm
(
e.
g.,
Drager
Methyl
Bromide
Tube,
Model
#
0.2/
a
8103391).
However,
fumigators
and
other
industry
stakeholders
report
that
direct­
read
instruments
allow
reliable
measurement
only
as
low
as
2
ppm.
The
Agency
has
determined
that
the
use
of
respiratory
protection
can
be
discontinued
within
buffer
zones
specified
above
based
on
either
of
the
following
two
procedures:

 
Procedure
1:
Daily
exposure
to
MeBr
without
a
respirator
is
less
than
240
minutes.
If
four
consecutive
air
samples
are
taken
at
least
15
minutes
apart
within
the
treated
area
using
direct
read
devices
show
that
air
concentrations
of
2
ppm
or
less,
then
use
of
respiratory
protection
may
be
discontinued.
At
least
two
additional
samples
must
then
be
taken
at
least
30
minutes
apart.
If
either
of
these
samples
is
greater
than
2
ppm,
the
use
of
respiratory
protection
must
be
resumed,
and
can
only
be
discontinued
again
if
two
sample
readings
taken
at
least
15
minutes
apart
are
less
than
2
ppm.

 
Procedure
2:
Daily
exposure
to
MeBr
without
a
respirator
is
less
than
160
minutes.
If
four
consecutive
air
samples
are
taken
at
least
15
minutes
apart
within
the
treated
area
using
direct
read
devices
show
air
concentrations
of
3
ppm
or
less,
then
use
of
respiratory
protection
may
be
discontinued.
At
least
two
additional
35
samples
must
then
be
taken
at
least
30
minutes
apart.
If
either
of
these
samples
is
greater
than
3
ppm,
the
use
of
respiratory
protection
must
be
resumed,
and
can
only
be
discontinued
again
if
two
sample
readings
taken
at
least
15
minutes
apart
are
less
than
3
ppm.

Under
both
procedures,
air
samples
must
be
collected
at
least
hourly
throughout
the
workday
(
if
workers
are
present)
after
respiratory
protection
is
discontinued
to
ensure
concentrations
do
not
exceed
1
ppm
for
an
8
hour
TWA.
Records
of
sampling
must
be
kept
(
see
record
keeping
requirements
above).
The
Agency
has
determined
that
these
measures
will
ensure
that
worker
exposures
will
not
exceed
1
ppm
for
an
8­
hour
TWA.

3.
Storage
Areas
The
Agency
has
concerns
for
when
commodities
are
treated,
aerated
to
5
ppm
and
then
moved
to
storage
areas
where
air
exchange
rates
may
not
be
sufficient
to
allow
for
adequate
dissipation
of
methyl
bromide.
This
is
especially
a
concern
for
commodities
for
which
the
desorption
rate
of
methyl
bromide
is
slow
(
e.
g.,
walnuts,
timber,
etc.).
Air
monitoring
of
all
storage
areas
where
fumigated
commodities
are
located
must
be
conducted
before
workers
without
respiratory
protection
are
allowed
to
enter.
The
procedures
described
in
the
previous
section
must
be
followed
to
determine
when
worker
respiratory
protection
use
is
required
and
when
its
use
may
be
discontinued.

4.
Minimum
Aeration
Times
a.
Mechanical
and
Passive
Aeration
Enclosures
(
i.
e.,
areas
fumigated)
must
be
aerated
for
a
minimum
of
4
hours
if
mechanically
ventilated
using
fans,
or
12
hours
if
passively
ventilated.
At
the
end
of
the
aeration
process,
the
concentration
within
the
treated
commodity
(
or
space
for
structural
fumigations)
must
be
no
greater
than
5
ppm.
The
commodity
may
not
be
moved
from
the
enclosure
during
the
aeration
period,
except
where
noted
below.
For
some
commodities
and
enclosure
types,
aeration
times
of
longer
than
12
hours
may
be
needed
to
achieve
concentrations
of
5
ppm
or
less.

b.
Exceptions
Exceptions
for
these
minimum
aeration
times
are
allowed
under
the
following
conditions:

 
Vacuum
Chambers
­
Vacuum
chambers
that
provide
at
least
4
air
changes
per
hour.

 
Aeration
Outside
of
Fumigation
Enclosure
­
Fumigated
commodity
may
be
removed
from
the
fumigation
enclosure
as
soon
as
the
concentration
of
methyl
bromide
in
the
air
spaces
between
the
stacked
commodities
is
less
than
5
ppm
and
at
least
ten
air
changes
have
been
completed.
However,
the
minimum
aeration
36
time
(
4
or
12
hours)
must
be
provided
before
anyone
is
permitted
to
handle
(
process,
package)
the
treated
commodity.
In
other
words,
the
minimum
aeration
time
must
be
provided
before
people
can
handle
the
treated
commodity.
The
aeration
can
occur
within
the
enclosure,
a
storage
area,
or
some
other
holding
area.
The
length
of
time
for
which
aeration
is
required
can
be
prorated
between
the
time
inside
the
enclosure
and
outside
the
enclosure
if
the
method
of
aeration
is
changed.
For
example,
if
two
hours
of
mechanical
aeration
are
completed
before
the
commodity
is
removed
from
the
enclosure,
one­
half
of
the
required
aeration
has
been
achieved.
Therefore,
six
hours
of
passive
aeration
outside
of
the
enclosure
is
still
required
(
the
second
half
of
the
required
aeration).

 
Air
Monitoring
­
Various
types
of
monitoring
may
indicate
that
the
minimum
aeration
times
can
be
reduced.
This
may
involve
testing
the
rate
of
desorption
for
a
specific
commodity
or
monitoring
workers
with
charcoal
tubes,
Summa
canisters,
long­
path
infrared
spectrometer,
or
some
other
sensitive
method.
This
type
of
monitoring
cannot
be
done
with
colorimetric
detector
tubes.
Air
monitoring
must
be
done
with
devices
that
have
a
limit
of
detection
(
LOD)
of
0.5
ppm
or
lower.
Additional
guidance
regarding
monitoring
requirements
will
be
provided
in
the
Agency
methyl
bromide
commodity
fumigation
reference
manual.

The
facts
that
support
using
any
of
these
exceptions
must
be
clearly
explained
in
the
site's
FMP.

V.
What
Registrants
Need
to
Do
The
Agency
has
determined
that
with
the
mitigation
measures
identified
in
this
document,
use
of
methyl
bromide
to
fumigate
commodities
is
eligible
for
reregistration;
however,
additional
data
are
required
to
confirm
this
decision.
In
the
near
future,
the
Agency
intends
to
issue
Data
Call­
In
Notices
(
DCIs)
requiring
product
specific
data
and
generic
(
technical

confirmatory
data.
Generally,
registrants
will
have
90
days
from
receipt
of
a
DCI
to
complete
and
submit
response
forms
or
request
time
extension
and/
or
waiver
requests
with
a
full
written
justification.
For
product
specific
data,
the
registrant
will
have
8
months
to
submit
data
and
amended

that
will
take
place.
The
time
of
the
aeration
period
must

included
in
the
site­

fumigation
management
plan.

Except
as
provided
below,
enclosures
where
methyl
bromide
fumigation
took
place
must
be
aerated
for
a
minimum
of:

­­
4
hours
if
mechanically
ventilated
using
fans,
or
­­
12
hours
if
passively
ventilated
using
windows
or
doors
only.

The
minimum
aeration
time
is
measured
starting
at
the
end
of
the
fumigation
period
and
the
beginning
of
aeration
through
mechanical
or
passive
means.
At
the
end
of
the
aeration
period,
the
methyl
bromide
air
concentration
level
within
the
treated
commodity
or
within
the
space
for
structural
fumigation
must
be
measured.
Until
the
air
concentration
level
is
measured
to
be
5
ppm
or
less,
the
commodity
cannot
be
moved
from
the
fumigation
enclosure.

Exceptions
to
minimum
aeration
times:
Enclosures
where
methyl
bromide
fumigation
took
place
need
not
be
aerated
for
the
minimum
aeration
times
listed
here,
provided:

­­
a
vacuum
chamber
is
used
that
provides
at
least
4
air
exchanges
per
hour.
The
minimum
aeration
time
for
such
a
vacuum
chamber
is
the
time
from
the
start
of
aeration
until
10
air
exchanges
have
been
completed.
If
this
exception
to
the
minimum
aeration
period
is
used,
the
site­
specific
fumigant

plan
must
explain
the
basis
for

Moving
Fumigated
Commodities
from
the
Fumigation
Enclosure
"
MOVING
FUMIGATED
COMMODITIES
TO
SEPARATE
STORAGE
AREAS
Fumigated
commodities
may
be
moved
from
the
fumigation
enclosure
to
storage
areas,
provided
­­
the
concentration
of
methyl
bromide
in
the
air
spaces
among
the
stacked
commodities
is
measured
to
be
5
ppm
or
less,
and
­­
at
least
ten
air
exchanges
have
been
completed
in
the
fumigation
enclosure.

However,
the
minimum
aeration
time
must
be
completed
in
the
storage
area
before
workers
are
permitted
to
process,
package,
or
otherwise
handle
the
treated
commodity.
The
total
aeration
time
is
measured
from
the
start
of
aeration
in
the
fumigation
enclosure
and
includes
aeration
time
in
the
fumigation
enclosure
plus
any
aeration
that
occurs
in
a
holding
area
and
aeration
that
occurs
in
the
storage
area.
If
a
combination
of
aeration
techniques
are
used,
the
effective
aeration
time
can
be
prorated
to
reflect
the
techniques
used.
For
example,
if
two
hours
of
mechanical
ventilation
occur
in
the
fumigation
enclosure
before
the
commodity
is
moved
to
a
storage
area,
then
that
constitutes
one­
half
of
the
required
minimum
aeration
time
(
2
hours
out
of
4
hours
for
mechanical
ventilation).
If
the
storage
area
uses
passive
ventilation,
then
the
storage
area
would
have
to
be
passively
ventilated
for
at
least
6
hours
(
one
half
of
the
12
hours
for
passive
ventilation)
before
workers
would
be
permitted
to
handle
the
treated
commodity."
