1­
hour
test
runs
either
the
temperature
at
the
inlet
to
each
catalyst
bed
or
the
temperature
in
the
combustion
chamber.
For
regenerative
catalytic
oxidizers,
you
must
calculate
the
average
of
the
temperature
measurements
from
each
catalyst
bed
inlet
or
within
the
combustion
chamber
prior
to
reducing
the
25
temperature
data
to
15­
minute
averages
for
purposes
of
establishing
your
minimum
catalytic
oxidizer
temperature.

The
minimum
catalytic
oxidizer
temperature
must
then
be
established
as
the
average
of
the
three
minimum
15­
minute
temperatures
monitored
during
the
three
test
runs.
Multiple
three­
run
performance
tests
may
be
conducted
to

bed
temperature,
you
may
use
multiple
thermocouples
in
representative
locations
throughout
the
biofilter
bed
and
calculate
the
average
biofilter
bed
temperature
across
these
thermocouples
prior
to
reducing
the
temperature
data
to
15­

minute
averages
for
purposes
of
establishing
biofilter
bed
26
temperature
limits.
The
biofilter
bed
temperature
range
must
be
established
as
the
minimum
and
maximum
15­
minute
biofilter
bed
temperatures
monitored
during

tests
provided
that
the
data
used
to
establish
the
temperature
ranges
have
been
obtained
using
the

Alternative
Procedure
to
Determine
Capture
Efficiency
from
Enclosures
Around
Hot
Presses
in
the
Plywood
and
Composite
Wood
Products
Industry
Using
Sulfur
Hexafluoride
Tracer
Gas
1.0
Scope
and
Application.

This
procedure
has
been
developed
specifically
for
the
rule
for
the
plywood
and
composite
wood
products
(
PCWP)
industry
and
is
used
to
determine
the
capture
efficiency
of
a
partial
hot
press
enclosure
in
that
industry.
This
procedure
is
applicable
for
the
determination
of
capture
efficiency
for
enclosures
around
hot
presses
and
is
an
alternative
to
the
construction
of
temporary
total
enclosures
(
TTEs).
Sulfur
hexafluoride
(
SF6)
is
used
as
a
tracer
gas
(
other
tracer
gases
may
be
used
if
approved
by
the
Administrator).
This
gas
is
not
indigenous
to
the
ambient
atmosphere
and
is
nonreactive.

This
procedure
uses
infrared
spectrometry
(
IR)
as
the
analytical
technique.
When
the
infrared
spectrometer
used
is
a
Fourier­
Transform
Infrared
spectrometer
(
FTIR),
an
92
alternate
instrument
calibration
procedure
may
be
used;
the
alternate
calibration
procedure
is
the
calibration
transfer
standard
(
CTS)
procedure
of
EPA
Method
320.
Other
analytical
techniques
which
are
capable
of
equivalent
Method
Performance
(
Section
13.0)
also
may
be
used.
Specifically,
gas
chromatography
with
electron
capture
detection
(
GC/
ECD)
is
an
applicable
technique
for
analysis
of
SF6.

2.0
Summary
of
Method.

A
constant
mass
flow
rate
of
SF6
tracer
gas
is
released
through
manifolds
at
multiple
locations
within
the
enclosure
to
mimic
the
release
of
HAP
during
the
press
process.
This
test
method
requires
a
minimum
of
three
SF6
injection
points
(
two
at
the
press
unloader
and
one
at
the
press)
and
provides
details
about
considerations
for
locating
the
injection
points.
An
infrared
spectrometer
(
or
GC/
ECD)
is
used
to
measure
the
concentration
of
SF6
at
the
inlet
duct
to
the
control
device
(
outlet
duct
from
enclosure).
Simultaneously,
EPA
Method
2
is
used
to
measure
the
flow
rate
at
the
inlet
duct
to
the
control
device.
The
concentration
and
flow
rate
measurements
are
used
to
calculate
the
mass
emission
rate
of
SF6
at
the
control
device
inlet.
Through
calculation
of
the
mass
of
SF6
released
through
the
manifolds
and
the
mass
of
SF6
measured
at
the
inlet
to
the
control
device,
the
capture
efficiency
of
the
enclosure
is
calculated.

In
addition,
optional
samples
of
the
ambient
air
may
be
taken
at
locations
around
the
perimeter
of
the
enclosure
to
quantify
the
ambient
concentration
of
SF6
and
to
identify
those
areas
of
the
enclosure
that
may
be
performing
less
efficiently;
these
samples
would
be
taken
using
disposable
syringes
and
would
be
analyzed
using
a
GC/
ECD.

Finally,
in
addition
to
the
requirements
specified
in
this
procedure,
the
data
quality
objectives
(
DQO)
or
lower
confidence
limit
(
LCL)
criteria
specified
in
Appendix
A

Data
Quality
Objective
and
Lower

Protocols
and
Test
Methods,
must
also
be
satisfied.
A
minimum
of
three
test
runs
are
required
for
this
procedure;
however,
additional
test
runs
may
be
required
based
on
the
results
of
the
DQO
or
LCL
analysis.

3.0
Definitions.

3.1
Capture
efficiency
(
CE).
The
weight
per
unit
time
of
SF6
entering
the
control
device
divided
by
the
weight
per
unit
time
of
SF6
released
through
manifolds
at
multiple
93
locations
within
the
enclosure.

3.2
Control
device
(
CD).
The
equipment
used
to
reduce,
by
destruction
or
removal,
press
exhaust
air
pollutants
prior
to
discharge
to
the
ambient
air.

3.3
Control/
destruction
efficiency
(
DE).
The
volatile
organic
compound
or
HAP
removal
efficiency
of
the
control
device.

3.4
Data
Quality
Objective
(
DQO)
Approach.
A
statistical
procedure
to
determine
the
precision
of
the
data
from
a
test
series
and
to
qualify
the
data
in
the
determination
of
capture
efficiency
for
compliance
purposes.
If
the
results
of
the
DQO
analysis
of
the
initial
three
test
runs
do
not
satisfy
the
DQO
criterion,
the
LCL
approach
can
be
used
or
additional
test
runs
must
be
conducted.
If
additional
test
runs
are
conducted,
then
the
DQO
or
LCL
analysis
is
conducted
using
the
data
from
both
the
initial
test
runs
and
all
additional
test
runs.

3.5
Lower
Confidence
Limit
(
LCL)
Approach.
An
alternative
statistical
procedure
that
can
be
used
to
qualify
data
in
the
determination
of
capture
efficiency
for
compliance
purposes.
If
the
results
of
the
LCL
approach
produce
a
CE
that
is
too
low
for
demonstrating
compliance,
then
additional
test
runs
must
be
conducted
until
the
LCL
or
DQO
is
met.
As
with
the
DQO,
data
from
all
valid
test
runs
must
be
used
in
the
calculation.

3.6
Minimum
Measurement
Level
(
MML).
The
minimum
tracer
gas
concentration
expected
to
be
measured
during
the
test
series.
This
value
is
selected
by
the
tester
based
on
the
capabilities
of
the
IR
spectrometer
(
or
GC/
ECD)
and
the
other
known
or
measured
parameters
of
the
hot
press
enclosure
to
be
tested.
The
selected
MML
must
be
above
the
low­

calibration
standard
and
preferably
below
the
mid­
level
calibration
standard.

Safety.

Sulfur
hexafluoride
is
a
colorless,
odorless,
nonflammable
liquefied
gas.
It
is
stable
and
nonreactive
and,
because
it
is
noncorrosive,
most
structural
materials
are
compatible
with
it.
The
Occupational
Safety
and
Health
Administration
PEL­
TWA
and
TLV­
TWA
concentrations
are
1,000
parts
per
million.
Sulfur
hexafluoride
is
an
asphyxiant.
Exposure
to
an
oxygen­
deficient
atmosphere
(
less
than
19.5
percent
oxygen)
may
cause
dizziness,
drowsiness,
nausea,
vomiting,
excess
salivation,
diminished
mental
alertness,
loss
of
consciousness,
and
death.
Exposure
to
atmospheres
containing
less
than

will
bring
about
unconsciousness
without
warning
and
so
quickly
that
the
individuals
cannot
help
themselves.
Contact
with
liquid
or
cold
vapor
may
cause
frostbite.
Avoid
breathing
sulfur
hexafluoride
gas.

control
meter
can
be
used
for
this
method.
The
meter
must
be
accurate
to
within
±
5
percent
at
the
flow
rate
used.
This
means
that
the
flow
meter
must
be
calibrated
against
a
primary
standard
for
flow
measurement
at
the
appropriate
flow
rate.

6.2
Measurement
of
Tracer
Gas
Concentration.

6.2.1
Sampling
Probes.
Use
Pyrex
or
stainless
steel
sampling
probes
of
sufficient
length
to
reach
the
traverse
points
calculated
according
to
EPA
Method

pump
capable
of
extracting
sufficient
sample
from
the
duct
and
transporting
to
the
analytical
instrument.

6.2.4
Sample
Conditioning
System.
Use
a
particulate
filter
sufficient
to
protect
the
sampling
pump
and
analytical
instrument.
At
the
discretion
of
the
tester
and
depending
on
the
equipment
used
and
the
moisture
content
of
the
exhaust
gas,
it
may
be
necessary
to
further
condition
the
sample
by
removing
moisture
using
a
condenser.

6.2.5
Analytical
Instrument.
Use
one
of
the
following
analytical
instruments.

6.2.1.1
Spectrometer.
Use
an
infrared
spectrometer
designed
to
measuring
SF6
tracer
gas
and
capable
of
meeting
or
exceeding
the
specifications
of
this
procedure.
An
FTIR
meeting
the
specifications
of
Method
320
may
be
used.

6.2.1.2
GC/
ECD.
Use
a
GC/
ECD
designed
to
measure
SF6
tracer
gas
and
capable
of
meeting
or
exceeding
the
specifications
of
this
procedure.

6.2.6
Recorder.
At
a
minimum,
use
a
recorder
with
96
linear
strip
chart.
An
automated
data
acquisition
system
(
DAS)
is
recommended.

6.3
Exhaust
Gas
Flow
Rate
Measurement.
Use
equipment
specified
for
EPA
Methods
2,
3,
and
4
for
measuring
flow
rate
of
exhaust
gas
at
the
inlet
to
the
control
device.

7.0
Reagents
and
Standards.

7.1
Tracer
Gas.
Use
SF6
as
the
tracer
gas.
The
manufacturer
of
the
SF6
tracer
gas
should
provide
a
recommended
shelf
life
for
the
tracer
gas
cylinder
over
which
the
concentration
does
not
change
more
than
±
2
percent
from
the
certified
value.
A
gas
mixture
of
SF6
diluted
with
nitrogen
should
be
used;
based
on
experience
and
calculations,
pure
SF6
gas
is
not
necessary
to
conduct
tracer
gas
testing.
Select
a
concentration
and
flow
rate
that
is
appropriate
for
the
analytical
instrument's
detection
limit,
the
minimum
measurement
level
(
MML),
and
the
exhaust
gas
flow
rate
from
the
enclosure
(
see
section
8.1.1).
You
may
use
a
tracer
gas
other
than
SF6
with
the
prior
approval
of
the
Administrator.
If
you
use
an
approved
tracer
gas
other
than
SF6,
all
references
to
SF6
in
this
protocol
instead
refer
to
the
approved
tracer
gas.

7.2
Calibration
Gases.
The
SF6
calibration
gases
required
will
be
dependent
on
the
selected
MML
and
the
appropriate
span
selected
for
the
test.
Commercial
cylinder
gases
certified
by
the
manufacturer
to
be
accurate
to
within
1
percent
of
the
certified
label
value
are
preferable,
although
cylinder
gases
certified
by
the
manufacturer
to
2
percent
accuracy
are
allowed.
Additionally,
the
manufacturer
of
the
SF6
calibration
gases
should
provide
a
recommended
shelf
life
for
each
calibration
gas
cylinder
over
which
the
concentration
does
not
change
more
than
±
2
percent
from
the
certified
value.
Another
option
allowed
by
this
method
is
for
the
tester
to
obtain
high
concentration
certified
cylinder
gases
and
then
use
a
dilution
system
meeting
the
requirements
of
EPA
Method
205,
40
CFR
part
51,
Appendix
M,
to
make
multi­
level
calibration
gas
standards.
Low­
level,
mid­
level,
and
high­
level
calibration
gases
will
be
required.
The
MML
must
be
above
the
low­
level
standard,
the
high­
level
standard
must
be
no
more
than
four
times
the
low­
level
standard,
and
the
mid­
level
standard
must
be
approximately
halfway
between
the
high­
and
low­
level
standards.
See
section
12.1
for
an
example
calculation
of
this
procedure.
Note:
If
using
an
FTIR
as
the
analytical
instrument,
the
tester
has
the
option
of
following
the
CTS
procedures
of
Method
320;
the
calibration
standards
(
and
procedures)
specified
in
Method
320
may
be
used
in
lieu
of
the
97
calibration
standards
and
procedures
in
this
protocol.

7.2.1
Zero
Gas.
High
purity
nitrogen.

7.2.2
Low­
Level
Calibration
Gas.
An
SF6
calibration
gas
in
nitrogen
with
a
concentration
equivalent
to
20
to
30
percent
of
the
applicable
span
value.

7.2.3
Mid­
Level
Calibration
Gas.
An
SF6
calibration
gas
in
nitrogen
with
a
concentration
equivalent
to
45
to
55
percent
of
the
applicable
span
value.

7.2.4
High­
Level
Calibration
Gas.
An
SF6
calibration
gas
in
nitrogen
with
a
concentration
equivalent
to
80
to
90
percent
of
the
applicable
span
value.

Sample
Collection,
Preservation,
Storage,
and
Transport.

8.1
Test
Design.

8.1.1
Determination
of
Minimum
Tracer
Gas
Flow
Rate.

8.1.1.1
Determine
(
via
design
calculations
or
measurements)
the
approximate
flow
rate
of
the
exhaust
gas
through
the
enclosure
(
acfm).

8.1.1.2
Calculate
the
minimum
tracer
gas
injection
rate
necessary
to
assure
a
detectable
SF6
concentration
at
the
exhaust
gas
measurement
point
(
see
section
12.1
for
calculation).

8.1.1.3
Select
a
flow
meter
for
the
injection
system
with
an
operating
range
appropriate
for
the
injection
rate
selected.

8.1.2
Determination
of
the
Approximate
Time
to
Reach
Equilibrium.

8.1.2.1
Determine
the
volume
of
the
enclosure.

8.1.2.2
Calculate
the
air
changes
per
minute
of
the
enclosure
by
dividing
the
approximate
exhaust
flow
rate
(
8.1.1.1
above)
by
the
enclosed
volume
(
8.1.2.1
above).

8.1.2.3
Calculate
the
time
at
which
the
tracer
concentration
in
the
enclosure
will
achieve
approximate
equilibrium.
Divide
3
by
the
air
changes
per
minute
(
8.1.2.2
above)
to
establish
this
time.
This
is
the
approximate
length
of
time
for
the
system
to
come
to
equilibrium.
Concentration
equilibrium
occurs
when
the
tracer
concentration
in
the
enclosure
stops
changing
as
a
function
of
time
for
a
constant
tracer
release
rate.
Because
the
press
is
continuously
cycling,
equilibrium
may
be
exhibited
by
a
repeating,
but
stable,
cyclic
pattern
rather
than
a
single
constant
concentration
value.
Assure
98
sufficient
tracer
gas
is
available
to
allow
the
system
to
come
to
equilibrium,
and
to
sample
for
a
minimum
of
20
minutes
and
repeat
the
procedure
for
a
minimum
of
three
test
runs.
Additional
test
runs
may
be
required
based
on
the
results
of
the
DQO
and
LCL
analyses
described
in
40
CFR
part
63,
subpart
KK,
Appendix
A.

8.1.3
Location
of
Injection
Points.
This
method
requires
a
minimum
of
three
tracer
gas
injection
points.
The
injection
points
should
be
located
within
leak
prone,
VOC/
HAP­
producing
areas
around

horizontally
within
12
inches
of
the

equipment.
One
potential
configuration
of

The
effect
of
wind,
exfiltration
through
the
building
envelope,
and
air
flowing
through
open
building
doors
should
be
considered
when
locating
tracer
gas
injection
points
within
the
enclosure.
The
injection
points
should
also
be
located
at
a
vertical
elevation
equal
to
the
VOC/
HAP
generating
zones.
The
injection
points
should
not
be
located
beneath
obstructions
that
would
prevent
a
natural
dispersion
of
the
gas.

selected
injection
points

8.1.4
Location
of
Flow
Measurement
and
Tracer
Sampling.
Accurate
CD
inlet
gas
flow
rate
measurements
are
critical
to
the
success
of
this
procedure.
Select
a
measurement
location
meeting
the
criteria
of
EPA
Method
1
(
40
CFR
part
60,
Appendix
A),
Sampling
and
Velocity
Traverses
for
Stationary
Sources.
Also,
when
selecting
the
measurement
location,
consider
whether
stratification
of
the
tracer
gas
is
likely
at
the
location
(
e.
g.,
do
not
select
a
location
immediately
after
a
point
of
air
in­
leakage
to
the
duct).

8.2
Tracer
Gas
Release.
Release
the
tracer
gas
at
a
calculated
flow
rate
(
see
section
12.1
for
calculation)
through
a
minimum
of
three
injection
manifolds
located
as
described
above
in
8.1.3.
The
tracer
gas
delivery
lines
must
be
routed
into
the
enclosure
and
attached
to
the
manifolds
without
violating
the
integrity
of
the
enclosure.

8.3
Pretest
Measurements.

8.3.1
Location
of
Sampling
Point(
s).
If
stratification
is
not
suspected
at
the
measurement
location,
select
a
single
sample
point
located
at
the
centroid
of
the
CD
inlet
duct
or
at
a
point
no
closer
to
the
CD
inlet
duct
walls
than
1
meter.
If
stratification
is
suspected,
establish
a
"
measurement
line"
that
passes
through
the
centroidal
area
and
in
the
direction
of
any
expected
stratification.
Locate
three
traverse
points
at
16.7,
50.0
and
83.3
percent
of
the
measurement
line
and
sample
from
99
each
of
these
three
points
during
each
run,
or
follow
the
procedure
in
section
8.3.2
to
verify
whether
stratification
does
or
does
not
exist.

8.3.2
Stratification
Verification.
The
presence
or
absence
of
stratification
can
be
verified
by
using
the
following
procedure.
While
the
facility
is
operating
normally,
initiate
tracer
gas
release
into
the
enclosure.
For
rectangular
ducts,
locate
at
least
nine
sample
points
in
the
cross
section
such
that
the
sample
points
are
the
centroids
of
similarly­
shaped,
equal
area
divisions
of
the
cross
section.
Measure
the
tracer
gas
concentration
at
each
point.
Calculate
the
mean
value
for
all
sample
points.
For
circular
ducts,
conduct
a
12­
point
traverse
(
i.
e.,
six
points
on
each
of
the
two
perpendicular
diameters)
locating
the
sample
points
as
described
in
40
CFR
part
60,
Appendix
A,
Method
1.
Perform
the
measurements
and
calculations
as
described
above.
Determine
if
the
mean
pollutant
concentration
is
more
than
10
percent
different
from
any
single
point.
If
so,
the
cross
section
is
considered
to
be
stratified,
and
the
tester
may
not
use
a
single
sample
point
location,
but
must
use
the
three
traverse
points
at
16.7,
50.0,
and
83.3
percent
of
the
entire
measurement
line.
Other
traverse
points
may
be
selected,
provided
that
they
can
be
shown
to
the
satisfaction
of
the
Administrator
to
provide
a
representative
sample
over
the
stack
or
duct
cross
section.

8.4
CD
Inlet
Gas
Flow
Rate
Measurements.
The
procedures
of
EPA
Methods
1­
4
(
40
CFR
part
60,
Appendix
A)
are
used
to
determine
the
CD
inlet
gas
flow
rate.
Molecular
weight
(
Method
3)
and
moisture
(
Method
4)
determinations
are
only
required
once
for
each
test
series.
However,
if
the
test
series
is
not
completed
within
24
hours,
then
the
molecular
weight
and
moisture
measurements
should
be
repeated
daily.
As
a
minimum,
velocity
measurements
are
conducted
according
to
the
procedures
of
Methods
1
and
2
before
and
after
each
test
run,
as
close
to
the
start
and
end
of
the
run
as
practicable.
A
velocity
measurement
between
two
runs
satisfies
both
the
criterion
of
"
after"
the
run
just
completed
and
"
before"
the
run
to
be
initiated.
Accurate
exhaust
gas
flow
rate
measurements
are
critical
to
the
success
of
this
procedure.
If
significant
temporal
variations
of
flow
rate
are
anticipated
during
the
test
run
under
normal
process
operating
conditions,
take
appropriate
steps
to
accurately
measure
the
flow
rate
during
the
test.
Examples
of
steps
that
might
be
taken
include:
1)
conducting
additional
velocity
traverses
during
the
test
run;
or
2)
continuously
monitoring
a
single
point
of
average
velocity
during
the
run
and
using
these
data,
in
conjunction
with
the
pre­
and
post­
test
traverses,
to
calculate
an
average
100
velocity
for
the
test
run.

8.5
Tracer
Gas
Measurement
Procedure.

8.5.1
Calibration
Error
Test.
Immediately
prior
to
the
emission
test
(
within
2
hours
of
the
start
of
the
test),
introduce
zero
gas
and
high­
level
calibration
gas
at
the
calibration
valve
assembly.
Zero
and
calibrate
the
analyzer
according
to
the
manufacturer's
procedures
using,
respectively,
nitrogen
and
the
calibration
gases.
Calculate
the
predicted
response
for
the
low­
level
and
mid­
level
gases
based
on
a
linear
response
line
between
the
zero
and
highlevel
response.
Then
introduce
the
low­
level
and
mid­
level
calibration
gases
successively
to
the
measurement
system.
Record
the
analyzer
responses
for
the
low­
level
and
midlevel
calibration
gases
and
determine
the
differences
between
the
measurement
system
responses
and
the
predicted
responses
using
the
equation
in
section
12.3.
These
differences
must
be
less
than
5
percent
of
the
respective
calibration
gas
value.
If
not,
the
measurement
system
must
be
replaced
or
repaired
prior
to
testing.
No
adjustments
to
the
measurement
system
shall
be
conducted
after
the
calibration
and
before
the
drift
determination
(
section
8.5.4).
If
adjustments
are
necessary
before
the
completion
of
the
test
series,
perform
the
drift
checks
prior
to
the
required
adjustments
and
repeat
the
calibration
following
the
adjustments.
If
multiple
electronic
ranges
are
to
be
used,
each
additional
range
must
be
checked
with
a
mid­
level
calibration
gas
to
verify
the
multiplication
factor.
Note:
If
using
an
FTIR
for
the
analytical
instrument,
you
may
choose
to
follow
the
pretest
preparation,
evaluation,
and
calibration
procedures
of
Method
320
(
section
8.0)
(
40
CFR
part
63,
Appendix
A)
in
lieu
of
the
above
procedure.

8.5.2
Response
Time
Test.
Conduct
this
test
once
prior
to
each
test
series.
Introduce
zero
gas
into
the
measurement
system
at
the
calibration
valve
assembly.
When
the
system
output
has
stabilized,
switch
quickly
to
the
high­
level
calibration
gas.
Record
the
time
from
the
concentration
change
to
the
measurement
system
response
equivalent
to
95
percent
of
the
step
change.
Repeat
the
test
three
times
and
average
the
results.

8.5.3
SF6
Measurement.
Sampling
of
the
enclosure
exhaust
gas
at
the
inlet
to
the
CD
should
begin
at
the
onset
of
tracer
gas
release.
If
necessary,
adjust
the
tracer
gas
injection
rate
such
that
the
measured
tracer
gas
concentration
at
the
CD
inlet
is
within
the
spectrometer's
calibration
range
(
i.
e.,
between
the
MML
and
the
span
value).
Once
the
tracer
gas
concentration
reaches
101
equilibrium,
the
SF6
concentration
should
be
measured
using
the
infrared
spectrometer
continuously
for
at
least
20
minutes
per
run.
Continuously
record
(
i.
e.,
record
at
least
once
per
minute)
the
concentration.
Conduct
at
least
three
test
runs.
On
the
recording
chart,
in
the
data
acquisition
system,
or
in
a
log
book,
make
a
note
of
periods
of
process
interruption
or
cyclic
operation
such
as
the
cycles
of
the
hot
press
operation.
Table
1
summarizes
the
physical
measurements
required
for
the
enclosure
testing.

Note:
If
a
GC/
ECD
is
used
as
the
analytical
instrument,
a
continuous
record
(
at
least
once
per
minute)
likely
will
not
be
possible;
make
a
minimum
of
five
injections
during
each
test
run.
Also,
the
minimum
test
run
duration
criterion
of
20
minutes
applies.

8.5.4
Drift
Determination.
Immediately
following
the
completion
of
the
test
run,
reintroduce
the
zero
and
mid­
level
calibration
gases,
one
at
a
time,
to
the
measurement
system
at
the
calibration
valve
assembly.
(
Make
no
adjustments
to
the
measurement
system
until
both
the
zero
and
calibration
drift
checks
are
made.)
Record
the
analyzer
responses
for
the
zero
and
mid­
level
calibration
gases
and
determine
the
difference
between
the
instrument
responses
for
each
gas
prior
to
and
after
the
emission
test
run
using
the
equation
in
section
12.4.
If
the
drift
values
exceed
the
specified
limits
(
section
13),
invalidate
the
test
results
preceding
the
check
and
repeat
the
test
following
corrections
to
the
measurement
system.
Alternatively,
recalibrate
the
test
measurement
system
as
in
section
8.5.1
and
report
the
results
using
both
sets
of
calibration
data
(
i.
e.,
data
determined
prior
to
the
test
period
and
data
determined
following
the
test
period).
Note:
If
using
an
FTIR
for
the
analytical
instrument,
you
may
choose
to
follow
the
post­
test
calibration
procedures
of
Method
320
(
section
8.11.2)
in
lieu
of
the
above
procedures.

8.6
Ambient
Air
Sampling
(
Optional).
Sampling
the
ambient
air
surrounding
the
enclosure
is
optional.
However,
taking
these
samples
during
the
capture
efficiency
testing
will
identify
those
areas
of
the
enclosure
that
may
be
performing
less
efficiently.

8.6.1
Location
of
Ambient
Samples
Outside
the
Enclosure
(
Optional).
In
selecting
the
sampling
locations
for
collecting
samples
of
the
ambient
air
surrounding
the
enclosure,
consider
potential
leak
points,
the
direction
of
the
release,
and
laminar
flow
characteristics
in
the
area
surrounding
the
enclosure.
Samples
should
be
collected
from
all
sides
of
the
enclosure,
downstream
in
the
prevailing
room
air
flow,
and
in
the
operating
personnel
occupancy
102
areas.

8.6.2
Collection
of
Ambient
Samples
(
Optional).
During
the
tracer
gas
release,
collect
ambient
samples
from
the
area
surrounding
the
enclosure
perimeter
at
predetermined
location
using
disposable
syringes
or
some
other
type
of
containers
that
are
non­
absorbent,
inert,
and
that
have
low
permeability
(
i.
e.,
polyvinyl
fluoride
film
or
polyester
film
sample
bags
or
polyethylene,
polypropylene,
nylon
or
glass
bottles).
The
use
of
disposable
syringes
allows
samples
to
be
injected
directly
into
a
gas
chromatograph.
Concentration
measurements
taken
around
the
perimeter
of
the
enclosure
provide
evidence
of
capture
performance
and
will
assist
in
the
identification
of
those
areas
of
the
enclosure
that
are
performing
less
efficiently.

8.6.3
Analysis
and
Storage
of
Ambient
Samples
(
Optional).
Analyze
the
ambient
samples
using
an
analytical
instrument
calibrated
and
operated
according
to
the
procedures
of
this
appendix
or
ASTM
E
260
and
ASTM
E
697.
Samples
may
be
analyzed
immediately
after
a
sample
is
taken,
or
they
may
be
stored
for
future
analysis.
Experience
has
shown
no
degradation
of
concentration
in
polypropylene
syringes
when
stored
for
several
months
as
long
as
the
needle
or
syringe
is
plugged.
Polypropylene
syringes
should
be
discarded
after
one
use
to
eliminate
the
possibility
of
cross
contamination
of
samples.

12.1
Estimate
MML
and
Span.
The
MML
is
the
minimum
measurement
level.
The
selection
of
this
level
is
at
the
discretion
of
the
tester.
However,
the
MML
must
be
higher
than
the
low­
level
calibration
standard,
and
the
tester
must
be
able
to
measure
at
this
level
with
a
precision
of

10
percent.
As
an
example,
select
the
MML
as
10
times
the
instrument's
published
detection
limit.
The
detection
limit
104
of
one
instrument
is
0.01
parts
per
million
by
volume
(
ppmv).
Therefore,
the
MML
would
be
0.10
ppmv.
Select
the
low­
level
calibration
standard
as
0.08
ppmv.
The
high­
level
standard
would
be
four
times
the
low­
level
standard
or
0.32
ppmv.
A
reasonable
mid­
level
standard
would
then
be
0.20
ppmv
(
halfway
between
the
low­
level
standard
and
the
highlevel
standard).
Finally,
the
span
value
would
be
approximately
0.40
ppmv
(
the
high­
level
value
is
80
percent
of
the
span).
In
this
example,
the
following
MML,
calibration
standards,
and
span
values
would
apply:
MML
=
0.10
ppmv
Low­
level
standard
=
0.08
ppmv
Mid­

standard
=
0.20
ppmv
High­

=
0.32
ppmv
Span
value
=
0.40

Estimate
Tracer

Injection
Rate
for
the
Given
Span.
To
estimate
the
minimum
and
maximum
tracer
gas
injection
rate,
assume
a
worst
case
capture
efficiency
of
80
percent,
and
calculate
the
tracer
gas
flow
rate
based
on
known
or
measured
parameters.
To
estimate
the
minimum
tracer

injection
rate,
assume
that
the
MML
concentration
(
10
times
the
IR
detection
limit
in
this
example)
is
desired
at
the
measurement

The
equation
to
calculate
enclosure
capture
efficiency
is
provided
below:

CE
=
(
SF6­
CD
÷
SF6­
INJ)
x
100
Where:
CE
=
capture
efficiency
SF6­
CD
=
mass
of

measured
at
the
inlet
to
the
CD
SF6­
INJ
=
mass
of
SF6
injected
from
the
tracer
source
into
the
enclosure
Calculate
the
CE
for
each
of
the
initial
three
test
runs.
Then
follow
the
procedures
outlined
in
section
12.6
to
calculate
the
overall
capture
efficiency.

12.6
Calculate
Overall
Capture
Efficiency.
After
calculating
the
capture
efficiency
for
each
of
the
initial
three
test
runs,
follow
the
procedures
in
40
CFR
part
63,
subpart
KK,
Appendix
A
to
determine
if
the
results
of
the
testing
can
be
used
in
determining
compliance
with
the
requirements
of
the
rule.
There
are
two
methods
that
can
be
used:
the
DQO
and
LCL
methods.
The
DQO
method
is
described
in
section
3
of
40
CFR
part
63,
subpart
KK,
Appendix
A
and
provides
a
measure
of
the
precision
of
the
capture
efficiency
testing
conducted.
Section
3
of
40
CFR
part
63,
subpart
KK,
Appendix
A
provides
an
example
calculation
using
results
from
a
facility.
If
the
DQO
criteria
are
met
using
the
first
set
of
three
test
runs,
then
the
facility
can
use
the
average
capture
efficiency
of
these
test
results
to
determine
the
capture
efficiency
of
the
enclosure.
If
the
DQO
criteria
are
not
met,
then
the
facility
can
conduct
another
set
of
three
runs
and
run
the
DQO
analysis
again
using
the
results
from
the
six
runs
OR
the
facility
can
elect
to
use
the
LCL
approach.

The
LCL
method
is
described
in
section
4
of
40
CFR
part
63,
subpart
KK,
Appendix
A
and
provides
sources
that
may
be
performing
much
better
than
their
regulatory
requirement,
a
screening
option
by
which
they
can
demonstrate
compliance.
The
LCL
approach
compares
the
80
percent
lower
confidence
limit
for
the
mean
measured
CE
value
to
the
applicable
regulatory
requirement.
If
the
LCL
capture
efficiency
is
107
higher
than
the
applicable
limit,
then
the
facility
is
in
initial
compliance
and
would
use
the
LCL
capture
efficiency
as
the
capture
efficiency
to
determine
compliance.
If
the
LCL
capture
efficiency
is
lower
than
the
applicable
limit,
then
the
facility
must
perform
additional
test
runs
and
rerun
the
DQO
or
LCL
analysis.
