Introduction
National
emission
standards
for
hazardous
air
pollutants
(
NESHAP)
were
proposed
for
the
plywood
and
composite
wood
products
(
PCWP)
industry
on
January
9,
2003.1
The
proposed
NESHAP
contained
a
production­
based
compliance
option
(
PBCO)
(
formerly
referred
to
as
production­
based
emission
limits).
The
PBCO
was
developed
for
process
units
that
use
pollution
prevention
or
are
otherwise
inherently
low­
emitting.
The
PBCO
consists
of
separate
emission
limits
for
specific
process
units
types.
The
PBCO
limits
are
in
terms
of
mass
per
unit
production
such
as
pounds
per
oven
dried
ton
(
lb/
ODT)
or
pounds
per
thousand
square
feet
(
lb/
MSF),
of
"
total
HAP."
"
Total
HAP"
is
defined
in
the
PCWP
NESHAP
as
the
total
emissions
of
the
following
six
HAP:
acetaldehyde,
acrolein,
formaldehyde,
methanol,
phenol,
and
propionaldehyde.
The
methodology
used
to
develop
the
proposed
PBCO
is
presented
in
a
separate
memorandum.
2
This
memorandum
discusses
the
changes
made
to
the
PBCO
limits
in
response
to
the
public
comments,
including
changes
in
how
non­
detect
measurements
are
treated
(
discussed
in
Section
II)
and
changes
to
the
PBCO
limits
due
to
revised
distinctions
among
process
units
(
discussed
in
Section
III).
The
final
PBCO
limits
are
presented
in
Section
IV.

II.
Treatment
of
Non­
Detect
Measurements
The
commenters
stated
that
most
of
the
PBCO
limit
could
be
consumed
by
using
one­
half
of
the
method
detection
limit
(
MDL)
for
non­
detect
measurements,
as
required
by
the
proposed
rule.
They
suggested
excluding
non­
detect
measurements
from
the
PBCO
limit
calculation
instead
of
using
one­
half
of
the
MDL.
In
response
to
these
comments,
an
analysis
was
conducted
to
determine
the
validity
of
the
commenters'
concerns
(
see
Attachment
A).
Based
on
the
analysis
2
included
in
Attachment
A,
we
agree
that
most
of
the
PBCO
limit
would
be
reached
by
using
onehalf
of
the
MDL
for
non­
detect
measurements.
Therefore,
we
changed
the
rule:
(
1)
to
exclude
non­
detect
measurements
from
the
PBCO
limit
calculations
when
all
test
runs
are
non­
detect,
and
(
2)
to
ensure
that
the
development
of
the
PBCO
limits
is
consistent
with
excluding
non­
detect
measurements
by
recalculating
the
limits
using
zero
for
non­
detect
measurements
when
all
test
runs
were
non­
detect.

III.
Changes
in
Process
Unit
Distinctions
1.
Primary
and
secondary
tube
dryers
In
the
proposed
PCWP
NESHAP,
single­
stage
and
multi­
stage
tube
dryers
were
treated
as
one
process
unit,
"
tube
dryers."
Commenters
requested
that
stages
in
multistage
tube
dryers
be
considered
separate
tube
dryers
so
that
different
compliance
options
can
be
used
for
various
dryer
stages.
Single­
stage
tube
dryers
include
only
a
primary
tube
dryer.
Multi­
stage
tube
drying
systems
incorporate
two
stages
in
series,
a
primary
tube
dryer
and
a
secondary
tube
dryer,
which
are
separated
by
an
emission
point
(
e.
g.,
a
cyclonic
collector).
Each
stage
of
a
multi­
stage
tube
dryer
functions
as
an
individual
dryer,
and
the
existing
source
MACT
floor
for
both
primary
tube
dryer
and
secondary
tube
dryers
is
the
same
(
e.
g.,
incineration­
based
control).
To
allow
for
more
flexibility
in
application
of
pollution
prevention
or
controls
to
the
different
stages
of
tube
dryers,
the
final
PCWP
rule
defines
the
stages
of
multi­
stage
tube
dryers
separately
in
definitions
of
"
primary
tube
dryer"
and
"
secondary
tube
dryer."
Primary
tube
dryers
include
single­
stage
tube
dryers
and
the
first
stage
of
multi­
stage
tube
dryers.
Secondary
tube
dryers
include
the
second
stage
of
multi­
stage
tube
dryers.
3
In
the
final
PCWP
rule,
both
primary
and
secondary
tube
dryers
are
required
to
apply
MACT
controls
and
each
will
have
a
separate
PBCO
limit.

2.
Conveyor
strand
dryers
One
definition
of
"
strand
dryers"
was
included
in
the
proposed
PCWP
rule
because,
at
proposal,
MACT
for
both
rotary
and
conveyor
strand
dryers
was
the
same
(
i.
e,
MACT
was
represented
by
incineration­
based
control
of
100
percent
of
the
exhaust
from
both
types
of
dryers).
One
commenter
recommended
that
conveyor
strand
dryers
be
exempt
from
control
requirements
in
the
final
rule
because
they
are
low­
emitting
dryers.
Conveyor
strand
dryers
have
three
zones,
each
with
its
own
heat
and
exhaust
flow.
Following
proposal,
the
MACT
floor
for
conveyor
strand
dryers
was
revised
to
require
control
of
exhaust
from
zone
1
for
existing
dryers
and
zones
1
and
2
for
new
dryers.
3
No
conveyor
strand
dryer
emissions
data
are
available
for
all
six
of
the
HAP
that
comprise
"
total
HAP."
Therefore,
a
PBCO
limit
cannot
be
developed
for
conveyor
strand
dryers.

IV.
PBCO
Limits
for
the
Final
PCWP
NESHAP
The
same
approach
used
to
establish
the
PBCO
limits
for
the
proposed
PCWP
NESHAP
was
used
to
establish
the
limits
for
the
final
NESHAP
(
except
that
non­
detect
measurements
were
3
treated
as
zero
for
the
final
analysis).
The
available
"
total
HAP"
test
data
were
grouped
according
to
the
process
unit
groups
with
controlled
MACT
floors.
The
highest
"
total
HAP"
test
value
was
identified
for
each
process
unit
group,
and
the
PBCO
limit
for
the
process
unit
group
was
established
by
multiplying
the
highest
test
value
by
0.1
to
reflect
a
90­
percent
reduction
from
the
highest
test.
Attachment
B
presents
the
data
set
used
to
establish
the
PBCO
limits
for
each
process
unit
group.
The
"
total
HAP"
summations
presented
in
Attachment
B
were
developed
using
zero
when
all
test
runs
were
below
the
MDL.
Table
1
summarizes
the
PBCO
limits
recommended
for
the
final
PCWP
NESHAP.
The
differences
in
the
proposed
and
final
PBCO
limits
are:
(
1)
a
secondary
tube
dryer
PBCO
limit
has
been
added,
and
(
2)
the
reconstituted
wood
product
board
cooler
PBCO
limit
decreased
from
0.015
to
0.014
lb/
MSF
3/
4"
due
to
use
of
zero
when
all
test
runs
were
below
the
MDL.

PBCO
(
i.

(

WP­
99.01)
or
EPA
Method
320
(
Appendix
A
to
40
CFR
part
63)
is
1
part
per
million
(
ppm).
The
process
parameters
in
Table
A1
were
combined
with
one­
half
of
1
ppm
(
i.
e.,
0.5
ppm)
to
calculate
the
percentage
of
the
PBCO
limit
that
would
be
consumed
if
all
of
the
six
HAP
were
not
detected
and
one­
half
of
MDL
was
used
to
calculate
"
total
HAP."

Table
A2
presents
the
calculations
of
the
percent
of
the
PBCO
limit
consumed
by
nondetect
measurements.
For
five
process
units,
use
of
one­
half
the
MDL
for
all
six
HAP
consumed
all
of
the
PBCO
limit.
Because
formaldehyde,
methanol,
and
acetaldehyde
are
the
most
commonly
detected
HAP
from
PCWP
process
units,
these
pollutants
were
eliminated
from
the
analysis.
However,
using
one­
half
of
the
MDL
for
acrolein,
phenol,
and
propionaldehyde
still
resulted
in
consumption
of
the
entire
PBCO
limit
for
five
process
units.
Based
on
the
analysis
presented
in
Tables
A1
and
A2,
it
appears
to
be
reasonable
to
allow
facilities
to
assume
zero
for
non­
detect
measurements
when
determining
compliance
with
the
PBCO,
provided
that
the
MDL
is
not
set
at
an
unreasonably
high
level
such
that
pollutants
cannot
be
detected.

Used

Uncontrolled
emissions
tests
including
all
six
of
the
HAP
that
comprise
"
total
HAP"
were
used
in
developing
the
PBCO.
In
summing
emissions
of
the
six
HAP,
zero
was
used
for
pollutants
with
non­
detects
for
all
emission
test
runs.
Emissions
tests
for
process
units
with
control
devices
that
alter
HAP
emissions
(
e.
g.,
RTO,
RCO,
WESP,
etc)
were
not
used
in
development
of
the
PBCO
limits.
The
PBCO
limits
were
developed
based
on
a
90­
percent
reduction
from
the
highest
uncontrolled
emission
test
result.
