BACKGROUND
On
June
17,
2002,
MeadWestvaco
petitioned
for
approval
of
a
Pavilion
Technologies
Software
CEM
NO
x
and
O

PEMS,
which
is
a
neural
network
based
computer
software
system
that
utilizes
turbine
sensor
inputs
to
produce
NO
x
and
O
2
outputs.
The
PEMS
is
installed
on
a
25
MW
GE
Frame

Model
MS5001P
combustion
turbine
at
the
Mahrt
Paper
Mill
in
Cottonton,
Alabama.
The
Mahrt
Paper
Mill
is
owned
and
operated
by
Mead
Coated

(
MeadWestvaco).
The
PEMS
was
installed
on
the
turbine
in
June
1998
to
comply
with
New
Source
Performance
Standards,
subpart
GG.

The
turbine
was
installed
in
1998
and
is
designed
to
cogenerate
steam
and
electricity
for
the
mill.
Natural

is
equipped
with
duct
burners
rated
at
170
mmBtu/

EPA'S
DETERMINATION
Under
Subpart
E,
the
owner
or
operator
of
a
unit
applying
to
the
Administrator
for
approval
of
an
AMS
must
demonstrate
that
the
AMS
has
the
same
or
better
precision,
reliability,
accessibility,
and
timeliness
(
PRAT)
as
provided
by
a
CEMS.
The
demonstration
must
be
made
by
comparing
the
AMS
to
a
contemporaneously
operating,
fully
certified
CEMS.
Sections
75.41
through
75.46
discuss
the
criteria
for
evaluating
PRAT,
daily
quality
assurance,
and
missing
data
substitution
for
the
AMS.
Section
75.48
details
the
information
that
must
be
included
in
the
application
in
order
to
demonstrate
that
the
criteria
in
§
§
75.41­
46
are
met.

The
following
paragraphs
describe
how
MeadWestvaco
meets
the
requirements
of
a
Subpart
E
AMS
petition.
As
detailed
below,
EPA's
approval
applies
only
to
the
Unit
X022
Mahrt
turbine
when
firing
natural
gas,
with
no
duct
burner
operation,
and
for
certain
PEMS
outputs,
i.
e.,
lb
NO
x/
mmBtu,
NO
x
(
ppm,
dry),
and
O
2
(%,
dry).
If
a
PEMS
input
parameter
value
goes
below
certain
minimum
or
above
certain
maximum
values,
MeadWestvaco
shall
report
the
maximum
potential
NO
x
emission
rate
(
MER).
During
startups,
shutdowns,
and
lean/
lean
turbine
operation,
oil­
fired
operation,
or
if
the
PEMS
alarms,
MeadWestvaco
must
report
the
NO
x
MER.
When
the
combustion
turbine
and
duct
burners
fire
natural
gas,
a
conservative
NO
x
alternative
substitute
data
value
shall
be
used.

1.
Precision
Under
§
75.41,
for
the
normal
unit
operating
level,
MeadWestvaco
must
provide
paired
AMS
and
fully
certified
CEMS
hourly
data
for
at
least
90
percent
of
the
hours
during
720
unit
operating
hours
for
the
primary
fuel
supply
and
for
at
least
24
successive
unit
operating
hours
for
all
alternative
fuel
supplies
that
have
significantly
different
sulfur
content.
MeadWestvaco
must
not
use
missing
data
substitution
procedures
to
provide
sample
data.
MeadWestvaco
may
also
demonstrate,
and
adjust
the
data
to
account
for,
any
lognormality
and
time
dependency
autocorrelation.
MeadWestvaco
must
pass
three
statistical
tests,
i.
e.,
a
linear
correlation
coefficient
(
r)
>
0.8,
an
Ftest
and
a
one­
tailed
t­
test
for
bias
described
in
appendix
A
to
part
75.
Further,
MeadWestvaco
must
provide
two
separate
time
series
plots
for
AMS
and
CEMS
data.
Each
data
plot
must
have
a
horizontal
axis
representing
the
clock
hour
and
calendar
date
of
the
readings
and
must
contain
a
separate
data
point
for
every
hour
for
the
duration
of
the
test.
One
data
plot
must
show
percentage
difference
vs.
time,
and
the
other
data
plot
must
show
AMS
and
CEMS
readings
vs.
time.
Finally,
a
plot
of
the
paired
AMS
(
on
the
vertical
axis)
and
CEMS
(
on
the
horizontal
axis)
concentrations
must
be
provided.

MeadWestvaco
provided
889
unit
operating
hours
of
paired
CEMS
vs
PEMS
data
when
the

Under
§
75.41(
b),
in
preparation
for
conducting
the
required
statistical
tests,
the
data
may
be
screened
for
lognormality
and
time
dependency
autocorrelation.
If
either
is
detected,
certain
calculation
adjustments
are
required.
MeadWestvaco
detected
neither
lognormality
nor
autocorrelation.
Therefore,
consistent
with
75.41(
b),
no
calculation
adjustments
were
made
to
the
data.
turbine
was
firing
natural
gas,
with
no
duct
burner
operation.
Since
duct
burners
operated
approximately
600
hours
during
the
almost
1500
hour
test
period,
only
about
60%
of
the
unit
operating
hours
during
the
test
period
were
utilized.
MeadWestvaco
did
not
technically
meet
the
requirement
of
using
at
least
90%
of
720
consecutive
unit
operating
hours,
required
by
§
75.41(
a)(
6).
However,
889
unit
operating
hours
of
valid
paired
data
(
more
than
90%
of
720
hours
or
648
hours)
were
submitted,
and
unit
operation
and
testing
were
continuous.
Therefore,
the
intent
of
the
90%
requirement
was
met.

The
table

shows
the
results
of
the
statistical

because
MeadWestvaco
uses

to
generate
the

EPA
finds
that
the
PEMS
NO

output
passed
each
of
the
three
statistical
tests.

The
PEMS
O

output
passed
the
T­
test
and
F­
test,
but
failed
the
r

However,
the
PEMS
O

concentration
was
always
within
0.5%
O

of
the
reference
method,
except
for
one
hourly
value
that
was
0.8%
O

different.
Because
this
hourly
value
was
the
second
data
point
collected
and
was
more
than
11
standard
deviations
below
the
mean
of
the
PEMS

EPA
considers
the

Under
these
circumstances,
EPA
finds
that
the
PEMS
O
2
output
was
within
the
error
allowed
by
part
75
for
a
CEMS
and
is
acceptable.

Further,
MeadWestvaco
supplied
the
appropriate
data
plots
concerning
the
paired
AMS
and
CEMS
data
under
§
§
75.41(
a)(
9)
and
(
c)(
2)(
i).

2.
Reliability
Under
§
75.42,
MeadWestvaco
must
demonstrate
that
the
PEMS
is
capable
of
providing
valid
1­
hr
averages
for
95.0
percent
or
more
of
unit
operating
hours
over
a
1­
yr
period
and
that
the
system
meets
the
applicable
requirements
of
appendix
B
of
part
75.
MeadWestvaco
complied
with
the
reliability
requirements
by
submitting
four
quarters
of
excess
emissions
reports
with
monitor
equipment
malfunction
times
indicating
greater
than
95.0%
PEMS
availability.
By
meeting
the
QA/
QC
requirements
described
in
this
letter,
MeadWestvaco
will
also
meet
the
applicable
appendix
B
quality
assurance
and
quality
control
(
QA/
QC)
requirements.

3.
Accessibility
and
Timeliness
Under
§
§
75.43
and
75.44,
MeadWestvaco
must
demonstrate
that
the
PEMS
meets
the
recordkeeping
and
reporting
requirements
of
subparts
F
and
G
of
part
75.
According
to
MeadWestvaco,
the
PEMS
meets
the
subpart
F
and
G
requirements.
For
example,
the
PEMS
"
will
provide
a
continuous,
quality
assured
permanent
record
of
certified
emissions
data
on
an
hourly
basis,"
and,
coupled
with
the
selected
recordkeeping
and
reporting
system,
"
will
be
capable
of
issuing
a
record
of
data
for
the
previous
day
within
24
hours."

4.
Quality
Assurance
Under
§
75.45,
MeadWestvaco
must
demonstrate
either
that
daily
tests
equivalent
to
those
in
appendix
B
of
part
75
can
be
performed
on
the
PEMS
or
that
such
tests
are
unnecessary
for
providing
quality­
assured
data.
Sections
75.48(
a)(
8)­(
11)
require
MeadWestvaco
to
submit:
a
detailed
description
of
the
process
used
to
collect
data,
including
location
and
method
of
ensuring
an
accurate
assessment
of
operating
hourly
conditions
on
a
real­
time
basis;
a
detailed
description
of
the
operation,
maintenance,
and
quality
assurance
procedures
for
the
AMS
as
required
in
part
75,
appendix
B;
a
description
of
methods
used
to
calculate
diluent
gas
concentration;
and
results
of
tests
and
measurements
necessary
to
substantiate
the
equivalency
of
the
AMS
to
a
fully
certified
CEMS.
EPA
finds
that
the
PEMS
will
meet
these
requirements
by
meeting
the
following:

(
a)
The
PEMS
uses
the
following
input
parameters:
splitter
valve
position,
gas
flow,
load,
inlet
air
temperature,
exhaust
gas
temperature,
and
burner
mode.
The
PEMS
input
parameters
must
stay
within
the
minimum
and
maximum
values
(
inclusive)
in
the
below
table
(
referred
to
as
"
the
PEMS
operating
envelope"),
unless
the
PEMS
is
retrained
according
to
paragraph
(
g)
below,
in
which
case,
the
new
training
values
will
supercede
the
values
in
the
5
below
table.
Except
for
burner
mode
parameter,
if
any
PEMS
input
parameter
value
goes
below
the
minimum
or
above
the
maximum
table
values
by
5
percent
or
more,
the
PEMS
shall
be
considered
out­
of­
control,
and
the
NO
x
MER
shall
be
used,
calculated
according
to
paragraph
(
i),
starting
with
the
hour
after
the
sensor
value
goes
outside
of
the
PEMS
operating
envelope
and
ending
with
the
hour
after
the
sensor
value
is
back
within
the
PEMS
operating
envelope.
Data
from
each
PEMS
input
parameter
shall
be
maintained
on
site
in
a
form
suitable
for
inspection
for
at
least
three
(
3)
years
from
the
date
of
each
record.
If
the
burner
mode
is
not
steady

The
sensors
for

parameters
must
be
maintained
in
accordance
with
the
manufacturer's
recommendations.
Further,
the
PEMS'
Sensor
Validation
System
identifies
and
reconciles
failed
sensors
by:
comparing
each
sensor
to
several
other
sensors;
determining,
based
on
the
comparison,
if
a
sensor
has
failed;
and
calculating
a
value
for
any
failed
sensor.
MeadWestvaco
must
check,
and
demonstrate,
that
the
Sensor
Validation
System:
validates
sensor
data
in
this
way
every
minute
of
PEMS
operation;
and
computes
hourly
averages
using
at
least
one
valid
data
point
in
each
fifteen
minute
quadrant
of
an
hour
(
producing
at
least
four
valid
data
points
per
hour),
where
the
unit
combusted
fuel
during
that
quadrant
of
an
hour,
to
comply
with
§
75.10(
d)(
1).

(
c)
MeadWestvaco
shall
implement
a
sensor
validation
alarm
system
to
inform
the
operator
when
sensors
need
repair
and
to
indicate
that
the
PEMS
is
out­
of­
control.
In
setting
up
the
alarm
system,
a
demonstration
shall
be
performed
at
a
minimum
of
four
different
PEMS
training
conditions,
which
must
be
representative
of
the
entire
range
of
expected
boiler
operations.
For
each
of
the
four
or
more
training
conditions,
the
demonstration
shall
consist
of
the
following:

(
1)
For
all
of
the
sensors
used
in
the
PEMS
model,
input
a
set
of
reference
sensor
values
that
were
recorded
either
during
the
training
of
the
PEMS
or
during
a
RATA
of
the
6
PEMS
(
these
values
will
all
be
within
the
PEMS
operating
envelope).
Verify
that
these
reference
inputs
produce
the
expected
PEMS
output,
i.
e.,
the
expected
NO
x
emission
rate;

(
2)
Perform
one­
sensor
failure
analysis,
as
follows.
Artificially
fail
one
of
the
sensors
and
then,
using
the
calculated
replacement
value
for
that
sensor
(
see
paragraph
(
b),
above),
assess
the
effect
on
the
accuracy
of
the
PEMS.
Calculate
the
percent
difference
between
the
reference
NO
x
emission
rate
from
step
(
1)
and
the
PEMS
output.
Repeat
this
procedure
for
each
sensor,
individually;

(
3)
Identify
the
sensor
failure
in
step
(
2)
that
results
in
the
worst
accuracy.
If
the
highest
percent
deviation
exceeds
+
10.0%,
then
set
up
the
PEMS
to
alarm
when
any
single
sensor
fails.
If
none
of
the
percent
difference
values
exceeds
10.0%,
proceed
to
step
(
4);

(
4)
Perform
two­
sensor
failure
analysis,
as
follows:
Artificially
fail
the
sensor
from
step
(
3)
that
produced
the
worst
accuracy
and
also
fail
one
of
the
other
sensors.
Then,
using
the
calculated
replacement
values
for
both
sensors,
assess
the
accuracy
of
the
PEMS
hourly
average
output,
as
in
step
(
2).
Repeat
this
procedure,
evaluating
each
sensor
in
turn
with
the
sensor
from
step
(
3);

(
5)
Identify
the
combination
of
dual
sensor
failures
that
results
in
the
worst
accuracy.
If
the
highest
percent
deviation
exceeds
+
10.0%,
then
set
up
the
PEMS
to
alarm
when
any
two
sensors
fail.
If
none
of
the
percent
difference
values
exceeds
10.0%,
then
set
up
the
PEMS
to
alarm
with
three
sensor
failures.

The
results
of
this
demonstration
shall
be
reported
in
the
Subpart

requirements
that
are
similar
to
the
checks
in

Based
on
the
results
of

the
following
modifications
to
ASTM
D6522­
00
are
required
to
make
the
method
more
practical
without
sacrificing
accuracy:
(
a)
NO

analyzers
must
provide
readings
to
0.1
ppm
to
improve
the
likelihood
of
passing
the
performance
specifications
for
sources
with
low
NO
x
levels;
(
b)
an
alternative
performance
specification
(
e.
g.,
+
1
ppm
difference
from
reference
value)
will
be
applied
to
take
account
of
sources
with
low
concentrations
of
NO
x;
and
(
c)
the
measurement
system
must
be
purged
with
ambient
air
between
gas
injections
during
the
stability
check,
to
reduce
degradation
of
electrochemical
cell
performance
(
see
footnote
6,

be
performed
in
the
following
order:
(
1)
Ensure
that
the

(
3)
Ensure
that
the

are
met.
(
4)
Perform
a
RATA,
following
the
procedures
in
section

except
use
three
different
operating
levels
(
low,
mid

as
defined
in
section
6.5.2.1
of
Part

Appendix
A.
However,
because
the
PEMS
is
only
approved
for

Missing
Data
Substitution
12
Under
§
75.46,
MeadWestvaco
must
demonstrate
that
all
missing
data
can
be
accounted
for
in
a
manner
consistent
with
the
applicable
missing
data
procedures
in
subpart
D.
MeadWestvaco
stated
that
the
PEMS
meets
the
subpart
D
requirements,
including
the
initial
missing
data
procedures,
determination
of
monitor
data
availability,
standard
missing
data
procedures,
and
either
the
PEMS
or
data
acquisition
and
handling
system
meet
the
appendix
D,
§
2.4
requirements
for
determining
missing
data
for
heat
input.
According
to
MeadWestvaco,
the
PEMS
can
determine
monitor
data
availability,
assess
the
operating
times
for
which
data
must
be
substituted,
and
recover
historical
data
from
the
PI
data
historian.
The
elapsed
out­
of­
control
time
of
the
PEMS
will
be
monitored,
allowing
the
PEMS
to
retrieve
the
data
necessary
to
perform
the
substitution.
Once
the
data
has
been
retrieved,
the
required
calculations
will
be
performed.
To
assist
in
analyzing
missing
data,
the
software
will
provide
data
managing
reports
that
will
allow
the
user
to
monitor
the
out­
ofcontrol
time
(
or
monitor
data
availability),
data
gap
analysis,
recovered
data
queries,
substituted
data
usage,
and
the
standard
reporting
requirements.

6.
Additional
Requirements
A
monitoring
plan
is
due
45
days
prior
to
the
initial
certification
tests
(
§
75.62)
described
in
paragraph
(
f)
above.
MeadWestvaco
shall
submit
the
operating

the
Alabama
Department
of
Environmental
Management
and

EDR
REPORTING
[
PREDICTIVE
EMISSIONS
MONITORING
SYSTEMS
(
PEMS)]

I.
Introduction
Table
A­
15,
below
includes
the
essential
EDR
record
types
for
units
that
have
received
approval
under
Subpart
E
of
Part
75
to
use
predictive
emissions
monitoring
systems
(
PEMS)
to
report
NO
x
emissions.
The
scope
of
Table
A­
15
is
limited
to
affected
oil
and
gas­
fired
units
(
i.
e.,
boilers
and
combustion
turbines)
that:


Have
a
single
unit­
single
stack
exhaust
configuration;
and

Use
Appendix
D
methodology
to
quantify
unit
heat
input;
and

Use
Appendices
D
and
G
to
account
for
SO
2
and
CO
2
mass
emissions
(
if
the
units
are
in
the
Acid
Rain
Program);
and

Do
not
co­
fire
oil
and
gas.

For
PEMS
reporting,
EDR
version
2.2
must
be
used,
since
fuel­
specific
missing
data
substitution
for
NO
x
emission
rate
is
required.
For
hourly
NO
x
emission
rate
reporting,
RT
320
is
used.
Hourly
200­
level
records
are
not
reported
for
either
NO
x
concentration
or
diluent
gas
(
O
2
or
CO
2)
concentration.

For
units
that
burn
more
than
one
fuel
type,
separate
PEMS
are
required
for
each
fuel.
Each
PEMS
should
be
reported
as
a
separate
monitoring
system
with
a
unique
monitoring
system
ID
in
RT
510.
Each
PEMS
will
require
its
own
set
of
certification,
recertification,
and
quality
assurance
tests.

II.
Interpreting
Table
A­
15
In
Table
A­
15,
the
first
column
identifies
the
record
type.
The
second
column
gives
a
brief
description
of
the
record
type.
The
third,
fourth,
and
fifth
columns
indicate
whether
the
record
type
must
be
reported
for
a
particular
type
of
submittal.
The
third
column
header,
"
MP,"
refers
to
monitoring
plan
submittals.
The
fourth
column
header,
"
CT,"
stands
for
certification
or
recertification
applications.
The
fifth
column
header,
"
QT,"
refers
to
electronic
data
report
submittals.
The
letter
codes
in
columns
3
through
5
are
defined
as
follows:

Y
This
record
type
is
required
for
this
type
of
submittal
(
monitoring
plan,
certification/
recertification
application
or
electronic

report)

N
This
record
type
is
not
appropriate
for
this
type
of
submittal.

O
This
record
type
is
appropriate,
but
optional
for
this
type
of
submittal.

A
This
record
type
may
be
required
for
this
submittal.
If
any
doubt
exists
as
to
the
need
to
submit
this
record
type,
consult
the
appropriate
EDR
instructions.

T
This
record
type
is
required
each
time
a
quality
assurance
test
(
e.
g.,
a
RATA)
is
performed.
