AGENCY:
Environmental
Protection
Agency
(
EPA).
ACTION:
Final
rule.

SUMMARY:
This
action
promulgates
national
emission
standards
for
hazardous
air
pollutants
(
NESHAP)
for
new
and
existing
refractory
products
manufacturing
facilities
and
implements
section
112(
d)
of
the
Clean
Air
Act
(
CAA)
by
requiring
all
major
sources
to
meet
HAP
emission
standards
reflecting
the
application
of
maximum
achievable
control
technology
(
MACT).
The
final
rule
will
protect
air
quality
and
promote
the
public
health
by
reducing
emissions
of
several
of
the
HAP
listed
in
section
112(
b)(
1)
of
the
CAA,
including
ethylene
glycol,
formaldehyde,
hydrogen
fluoride
(
HF),
hydrochloric
acid
(
HCl),
methanol,
phenol,
and
polycyclic
organic
matter
(
POM).
Exposure
to
these
substances
has
been
demonstrated
to
cause
adverse
health
effects
such
as
irritation
of
the
lung,
skin,
and
mucous
membranes,
effects
on
the
central
nervous
system,
and
damage
to
the
liver,
kidneys,
and
skeleton.
The
EPA
has
classified
the
HAP
formaldehyde
and
POM
as
probable
human
carcinogens.
The
final
rule
will
reduce
nationwide
emissions
of
HAP
from
these
facilities
by
an
estimated
124
megagrams
per
year
(
Mg/
yr)
(
137
tons
per
year
(
tpy)).

Background

What
is
the
Source
of
Authority
for
Development
of
NESHAP?
Section
112
of
the
CAA
requires
us
to
list
categories
and
subcategories
of
major
sources
and
area
sources
of
HAP
and
to
establish
NESHAP
for
the
listed
source
categories
and
subcategories.
Major
sources
of
HAP
are
those
that
have
the
potential
to
emit
greater
than
10
tpy
of
any
one
HAP
or
25
tpy
of
any
combination
of
HAP.
The
category
of
major
sources
covered
by
the
final
rule
was
listed
as
Chromium
Refractories
Production
on
July
16,
1992
(
57
FR
31576).
Section
112(
c)
of
the
CAA
allows
EPA
to
revise
the
source
category
list
at
any
time.
After
obtaining
information
from
chromium
refractories
manufacturing
plants
that
indicated
that
some
facilities
were
major
sources
due
to
HAP
emissions
from
the
manufacturing
of
nonchromium
refractories,
we
decided
to
expand
the
scope
of
the
source
category
to
include
most
manufacturers
of
refractory
products.
On
November
18,
1999,
we
revised
the
source
category
name
from
Chromium
Refractories
Production
to
Refractories
Manufacturing
(
64
FR
63025)
to
reflect
the
broadened
scope
of
the
source
category.
At
proposal
(
67
FR
42108,
June
20,
2002),
we
changed
the
source
category
name
from
Refractories
Manufacturing
to
Refractory
Products
Manufacturing
to
further
clarify
the
source
category.

B.
What
Criteria
Are
Used
in
the
Development
of
NESHAP?
Section
112
of
the
CAA
requires
that
we
establish
NESHAP
for
the
control
of
HAP
from
both
new
and
existing
major
sources.
The
CAA
requires
the
NESHAP
to
reflect
the
maximum
degree
of
reduction
in
emissions
of
HAP
that
is
achievable.
This
level
of
control
is
commonly
referred
to
as
MACT.
The
MACT
floor
is
the
minimum
control
level
allowed
for
NESHAP
and
is
defined
under
section
112(
d)(
3)
of
the
CAA.
In
essence,
the
MACT
floor
ensures
that
the
standards
are
set
at
a
level
that
assures
that
all
major
sources
achieve
the
level
of
control
at
least
as
stringent
as
that
already
achieved
by
the
better­
controlled
and
lower­
emitting
sources
in
each
source
category
or
subcategory.
For
new
sources,
the
MACT
floor
cannot
be
less
stringent
than
the
emission
control
that
is
achieved
in
practice
by
the
bestcontrolled
similar
source.
The
MACT
standards
for
existing
sources
can
be
less
stringent
than
standards
for
new
sources,
but
they
cannot
be
less
stringent
than
the
average
emission
limitation
achieved
by
the
bestperforming
12
percent
of
existing
sources
in
the
category
or
subcategory
(
or
the
best­
performing
five
sources
for
categories
or
subcategories
with
fewer
than
30
sources).
In
developing
MACT,
we
also
consider
control
options
that
are
more
stringent
than
the
floor.
We
may
establish
standards
more
stringent
than
the
floor
based
on
the
consideration
of
the
cost
of
achieving
the
emissions
reductions,
any
non­
air
quality
health
and
environmental
impacts,
and
energy
requirements.

C.
How
Was
the
Rule
Developed?
We
proposed
the
standards
for
refractory
products
manufacturing
on
June
20,
2002
(
67
FR
42108).
The
public
comment
period
lasted
from
June
20,
2002
to
August
19,
2002.
Industry
representatives,
regulatory
agencies,
environmental
groups,
and
the
general
public
were
given
the
opportunity
to
comment
on
the
proposed
rule
and
to
provide
additional
information
during
the
public
comment
period.
We
offered
at
proposal
the
opportunity
for
oral
presentation
of
data,
views,
or
arguments
concerning
the
proposed
rule
at
a
public
hearing.
One
organization
requested
a
public
hearing,
but
it
later
withdrew
the
request,
and
a
hearing
was
not
held.
We
received
a
total
of
eight
public
comments
on
the
proposed
rule.
Comments
were
submitted
by
three
industry
trade
associations,
two
refractory
products
manufacturing
companies,
and
two
other
companies.
One
trade
association
submitted
two
sets
of
comments.
The
final
rule
reflects
our
full
consideration
of
all
of
the
comments
received.
Major
public
comments
on
the
proposed
rule,
along
with
our
responses
to
those
comments,
are
summarized
in
this
preamble.

II.
Summary
of
the
Final
Rule
A.
What
Source
Category
Is
Affected
by
the
Final

clay
refractory
products
kilns.
Facilities
that
operate
thermal
process
sources
that
emit
organic
HAP
have
the
option
of
meeting
a
total
hydrocarbon
(
THC)
concentration
limit
of
20
parts
per
million
by
volume,
dry
basis
(
ppmvd),
corrected
to
18
percent
oxygen,
or
reducing
THC
mass
emissions
by
at
least
95
percent.
The
sources
that
will
be
subject
to
these
organic
HAP
emission
limits
include
new
and
existing
shape
dryers,
curing
ovens,
kilns,
coking
ovens,
and
defumers.
In
addition,
new
shape
preheaters
will
be
subject
to
these
same
emission
limits.
For
continuous
process
sources
of
organic
HAP,
the
format
of
the
emission
limits
is
a
3­
hour
block
average.
For
batch
process
sources,
the
format
of
the
standard
is
the
average
of
the
3­
hour
peak
THC
emissions
periods
for
two
test
runs.
For
affected
new
clay
refractory
products
kilns,
the
final
rule
includes
separate
emission
limits
for
HF
and
HCl.
For
affected
continuous
kilns,
you
will
have
to
meet
an
HF
emission
limit
of
0.019
kilograms
per
megagram
(
kg/
Mg)
(
0.038
pounds
per
ton
(
lb/
ton))
of
uncalcined
clay
processed
or
reduce
HF
mass
emissions
by
at
least
90
percent.
You
will
also
be
required
to
meet
an
HCl
emission
limit
of
0.091
kg/
Mg
(
0.18
lb/
ton)
of
product
or
reduce
uncontrolled
HCl
emissions
by
at
least
30
percent.
If
you
own
or
operate
a
new
affected
periodic
(
batch
process)
clay
refractory
products
kiln,
you
will
be
required
to
reduce
HF
emissions
by
at
least
90
percent
and
HCl
emissions
by
at
least
30
percent.

D.
What
Are
the
Operating
Limits?
Operating
limits
are
limits
on
operating
parameters
of
process
equipment
or
control
devices.
Today's
final
rule
specifies
process
and
control
device
operating
limits
for
thermal
process
sources
that
emit
organic
HAP
and
for
clay
refractory
kilns.
For
each
of
these
operating
limits,
you
will
be
required
to
measure
the
appropriate
operating
parameters
during
the
performance
test
and
establish
limits
on
the
operating
parameters
based
on
those
measurements.
Following
the
performance
test,
you
will
be
required
to
monitor
those
parameters
and
ensure
that
the
established
limits
are
not
exceeded.
For
affected
thermal
process
sources
that
emit
organic
HAP,
we
are
requiring
operating
limits
on
the
organic
HAP
processing
rate
and
the
operating
temperatures
of
your
control
devices.
The
operating
limit
on
the
organic
HAP
processing
rate
requires
you
to
maintain
the
rate
at
which
organic
HAP
are
processed
in
an
affected
process
unit
at
or
below
the
rate
measured
during
the
most
recent
performance
test.
For
sources
that
are
controlled
with
a
thermal
oxidizer,
you
will
be
required
to
establish
the
operating
limit
for
the
combustion
chamber
temperature.
For
affected
sources
that
are
controlled
with
a
catalytic
oxidizer,
you
will
be
required
to
establish
the
operating
limit
for
the
temperature
at
the
inlet
of
the
catalyst
bed.
Also,
you
must
check
the
activity
level
of
the
catalyst
at
least
every
12
months.
If
you
have
a
new
clay
refractory
products
kiln
that
is
controlled
with
a
dry
limestone
adsorber
(
DLA),
you
will
be
required
to
monitor
continuously
the
pressure
drop
across
the
DLA
and
check
the
limestone
feed
hopper
and
feeder
setting
at
least
daily
to
ensure
that
the
limestone
is
free
flowing.
You
will
also
be
required
to
document
the
source
of
the
limestone
used
during
the
most
recent
performance
test
and
maintain
records
that
demonstrate
that
the
source
of
limestone
has
not
changed.
If
you
own
or
operate
a
new
clay
refractory
products
kiln
that
is
controlled
with
dry
lime
injection
fabric
filters
(
DIFF)
or
dry
lime
scrubber/
fabric
filters
(
DLS/
FF),
you
will
be
required
to
install
a
bag
leak
detection
system,
initiate
corrective
action
within
1
hour
of
a
bag
leak
detection
system
alarm,
and
complete
corrective
actions
according
to
your
operation,
maintenance,
and
monitoring
(
OM&
M)
plan.
You
will
also
be
required
to
verify
at
least
once
every
8
hours
that
lime
is
free
flowing
and
record
the
lime
feeder
setting
daily
to
confirm
that
the
feeder
setting
is
at
or
above
the
level
established
during
the
most
recent
performance
test.
If
you
use
a
wet
scrubber,
you
will
be
required
to
establish
operating
limits
for
the
pressure
drop
across
the
scrubber,
liquid
pH,
liquid
flow
rate,
and
chemical
feed
rate
(
if
applicable).
If
you
use
a
control
device
or
technique
listed
in
today's
final
rule,
you
may
establish
operating
limits
for
alternative
operating
parameters
subject
to
prior
written
approval
by
the
Administrator
on
a
case­
by­
case
basis.
You
will
be
required
to
submit
the
application
for
approval
of
alternative
operating
parameters
no
later
than
the
notification
of
the
performance
test.
You
will
have
to
install,
operate,
and
maintain
the
alternative
parameter
monitoring
systems
in
accordance
with
the
application
approved
by
the
Administrator.

E.
What
Are
the
Work
Practice
Standards?
Today's
final
rule
establishes
work
practice
standards
for
existing
shape
preheaters
that
are
used
to
produce
pitch­
impregnated
refractory
products,
existing
and
new
pitch
working
tanks
that
are
used
to
produce
pitchimpregnated
refractory
products,
existing
and
new
chromium
refractory
products
kilns,
and
existing
clay
refractory
products
kilns.
If
you
operate
an
affected
existing
shape
preheater,
you
will
be
required
to
control
emissions
of
POM
from
the
shape
preheater
by
cleaning
the
residual
pitch
from
the
surfaces
of
the
baskets
or
containers
that
are
used
for
holding
refractory
shapes
in
a
shape
preheater
and
autoclave
at
least
every
ten
impregnation
cycles,
or
by
ducting
the
exhaust
from
the
shape
preheater
to
a
control
device
that
meets
the
applicable
emission
limits
for
thermal
process
sources
of
organic
HAP.
If
you
choose
to
clean
the
basket
surfaces,
you
may
remove
residual
pitch
by
abrasive
blasting
or
subject
the
baskets
to
a
thermal
process
cycle
that
matches
or
exceeds
the
temperature
and
cycle
time
of
the

is
ducted
to
a
thermal
or
catalytic
oxidizer
that
is
comparable
to
the
control
device
for
your
defumer
or
coking
oven.
If
you
choose
to
duct
shape
preheater
emissions
to
a
control
device,
you
may
duct
the
emissions
to
the
coking
oven
control
device,
defumer
control
device,
or
to
another
thermal
or
catalytic
oxidizer
that
is
comparable

F.
What
Are
the
Testing
and
Initial
Compliance
Requirements
for
Sources
Subject
to
Emission
Limits?
Under
today's
final
rule,
you
must
conduct
an
initial
performance
test
on
each
affected
source
to
demonstrate
initial
compliance
with
the
emission
limits.
In
accordance
with
40
CFR
63.7(
a)(
2),
you
are
required
to
conduct
the
test
within
180
days
after
the
compliance
date
using
specified
test
methods.
If
you
have
an
affected
existing
or
new
shape
dryer,
curing
oven,
kiln,
coking
oven,
or
defumer,
or
a
new
shape
preheater,
and
you
choose
to
comply
with
the
THC
concentration
limit
of
20
ppmvd
corrected
to
18
percent
oxygen,
you
must
measure
emissions
of
THC
in
stack
gases
exhausted
to
the
atmosphere
using
EPA
Method
25A
of
40
CFR
part
60,
appendix
A,
Determination
of
Total
Gaseous
Organic
Concentration
Using
a
Flame
Ionization
Analyzer.
You
must
also
measure
the
oxygen
concentration
of
the
stack
gas
using
EPA
Method
3A
of
40
CFR
part
60,
appendix
A,
Determination
of
Oxygen
and
Carbon
Dioxide
Concentrations
in
Emissions
From
Stationary
Sources
(
Instrumental
Analyzer
Procedure).
If
you
decide
to
comply
with
the
95
percent
THC
reduction
limit,
you
must
measure
THC
mass
emissions
at
the
inlet
and
outlet
of
the
control
device
using
EPA
Method
25A.
For
continuous
process
sources,
you
must
conduct
a
minimum
of
three
1­
hour
test
runs.
For
batch
process
sources,
you
must
conduct
at
least
two
test
runs.
Each
batch
process
test
run
must
be
conducted
over
a
separate
batch
cycle,
unless
you
manufacture
the
product
associated
with
the
maximum
organic
HAP
processing
rate
infrequently
and
it
will
disrupt
production
to
perform
the
compliance
test
over
multiple
process
cycles.
In
such
cases,
you
may
conduct
both
runs
of
the
performance
test
simultaneously
over
a
single
batch
process
cycle
using
paired
sampling
trains.
Today's
final
rule
requires
affected
batch
process
sources
to
be
tested
throughout
two
complete
batch
cycles
unless
you
develop
an
emissions
profile
or
meet
certain
conditions
for
terminating
a
performance
test
run
before
the
completion
of
the
batch
cycle.
If
you
choose
to
develop
an
emissions
profile,
you
must
sample
THC
emissions
throughout
a
complete
batch
cycle,
determine
the
average
THC
mass
emissions
rate
for
each
hour
of
the
batch
cycle,
and
identify
the
3­
hour
period
of
peak
THC
emissions.
During
any
subsequent
test
runs,
you
are
not
required
to
sample
emissions
outside
that
3­
hour
period
of
peak
THC
emissions.
During
subsequent
performance
tests,
you
will
have
to
complete
at
least
two
test
runs,
but
you
will
only
have
to
test
during
the
3­
hour
peak
emissions
period
for
each
run.
If
you
choose
not
to
develop
an
emissions
profile,
you
may
terminate
testing
before
the
completion
of
a
batch
cycle
if
you
meet
certain
conditions.
For
each
of
two
test
runs,
you
will
have
to
begin
testing
at
the
start
of
the
batch
cycle
and
continue
testing
for
at
least
3
hours
beyond
the
precise
time
when
the
process
reaches
peak
operating
temperature.
You
may
stop
the
test
run
at
that
time
if
you
can
show
that
the
following
conditions
are
met:
(
1)
THC
concentrations
are
not
increasing
over
the
3­
hour
period
since
the
process
peak
temperature
was
reached;
(
2)
at
least
1
hour
has
passed
since
any
reduction
in
the
operating
temperature
of
the
control
device
(
thermal
or
catalytic
oxidizer);
and
(
3)
either
the
average
THC
concentration
at
the
inlet
to
the
control
device
for
the
previous
hour
has
not
exceeded
20
ppmvd,
corrected
to
18
percent
oxygen,
or
your
source
met
the
applicable
emission
limit
at
the
control
device
outlet
during
each
of
the
previous
3
hours
after
the
process
reached
peak
temperature.
For
both
continuous
process
and
batch
process
performance
tests,
you
must
conduct
performance
tests
on
affected
thermal
process
sources
under
the
conditions
that
will
result
in
the
highest
levels
of
organic
HAP
emissions
expected
to
occur
for
that
affected
source.
You
determine
these
``
worstcase
conditions
by
taking
into
account
the
organic
HAP
processing
rate,
the
process
operating
temperatures,
and
the
processing
times.
The
organic
HAP
processing
rate
is
the
rate
at
which
the
mass
of
organic
HAP
materials
contained
in
refractory
shapes
are
processed
in
an
affected
thermal
process
source.
If
you
decide
to
start
production
of
a
refractory
product
that
is
likely
to
have
an
organic
HAP
processing
rate
that
is
more
than
10
percent
greater
than
the
rate
established
during
the
most
recent
performance
test,
you
will
be
required
to
conduct
a
new
performance
test
for
that
product
and
establish
a
new
operating
limit
for
the
organic
HAP
processing
rate.
You
will
also
have
to
conduct
a
new
performance
test
on
an
affected
uncontrolled
kiln
following
any
process
changes
that
are
likely
to
increase
kiln
emissions
of
organic
HAP.
If
the
source
is
a
batch
process
source
and
is
controlled
with
a
thermal
or
catalytic
oxidizer,
you
may
reduce
the
operating
temperature
of
the
control
device
or
shut
the
control
device
off
if
you
satisfy
all
of
the
following
conditions:
(
1)
You
do
not
use
an
emissions
profile
and
limit
testing
to
the
3­
hour
peak
emissions
period;
(
2)
at
least
3
hours
have
passed
since
the
process
unit
reached
its
maximum
temperature;
(
3)
the
applicable
emission
limit
(
THC
concentration
or
THC
percentage
reduction)
has
been
met
during
each
of
the
three
1­
hour
periods
since
the
process
reached
peak
temperature;
(
4)
mass
emissions
of
THC
have
not
increased
during
the
3­
hour
period
since
maximum
process
temperature
was
reached;
and
(
5)
either
the
average
THC
concentration
at
the
inlet
to
the
oxidizer
has
not
exceeded
20
ppmvd,
corrected
to
18
percent
oxygen,
for
at
least
1
hour,
or
the
applicable
emission
limit
has
been
met
during
each
of
the
four
15­
minute
periods
immediately
following
the
oxidizer
temperature
reduction.
If
you
elect
to
shut
off
or
reduce
the
temperature
of
a
thermal
or
catalytic
oxidizer
by
satisfying
these
conditions,
you
may
use
the
results
from
the
performance
test
to
establish
the
time
at
which
the
oxidizer
for
that
specific
source
can
be
shut
off
(
or
temperature
reduced)
during
the
production
of
other
refractory
products
that
use
organic
HAP.
For
any
such
product,
you
must
operate
the
oxidizer
at
a
temperature
at
least
as
high
as
that
established
during
the
performance
test,
minus
16
°
C
(
25
°
F),
from
the
start
of
the
batch
cycle
until
3
hours
have
passed
since
the
process
reached
its
peak
temperature.
You
will
have
to
maintain
that
oxidizer
temperature
for
the
same
length
of
time
beyond
the
process
peak
temperature
as
during
the
performance
test.
For
each
new
kiln
that
manufactures
clay
refractory
products,
you
must
measure
emissions
of
HF
and
HCl
using
one
of
three
methods:

of
production
for
each
test
run
using
the
mass
emission
rates
of
HF
and
HCl
and
the
rate
at
which
uncalcined
clay
is
processed
(
on
a
fired­
product
basis),
as
measured
during
your
performance
test.
To
determine
initial
compliance
with
any
of
the
percentage
reduction
emission
limits,
you
must
measure
mass
emissions
of
the
specific
HAP
(
HF
or
HCl)
at
the
inlet
and
outlet
of
the
control
device
for
each
test
run.
If
you
have
an
affected
batch
process
clay
refractory
kiln,
you
must
comply
with
the
percentage
reduction
limit.
You
will
be
required
to
test
throughout
two
complete
batch
cycles
unless
you
develop
an
emissions
profile.
If
you
choose
to
develop
an
emissions
profile,
you
must
sample
HF
and
HCl
emissions
throughout
one
complete
batch
cycle.
For
both
continuous
and
batch
process
kilns,
you
must
measure
and
record
the
average
uncalcined
clay
processing
rate
for
each
test
run.
If
you
own
or
operate
an
affected
new
clay
refractory
products
kiln
that
is
controlled
with
a
DLA,
and
you
decide
to
change
the
source
of
limestone,
you
must
repeat
the
performance
test
on
the
kiln
within
60
days
of
the
date
when
you
begin
using
limestone
from
the
new
limestone
source.
In
addition
to
the
procedures
previously
described,
you
will
be
required
to
follow
the
procedures
specified
in
EPA
Methods
1
to
4
of
appendix
A
of
40
CFR
part
60,
where
applicable.
You
must
perform

to
select
the
locations
of
sampling
points
and
the
number
of
traverse
points.
You
must
perform
EPA
Method
2,
Determination
of

molecular
weight.
You
must
perform
EPA
Method
4,
Determination
of
Moisture
Content
in
Stack
Gases,
to
measure
the
moisture

Prior
to
the
initial
performance
test,
you
must
install
any
continuous
parameter
monitoring
systems
(
CPMS)
that
are
required
for
demonstrating
continuous
compliance.
During
the
performance
test,
you
must
use
those
CPMS
to
establish
the
applicable
operating

temperature).

G.
What
Are
the
Initial
Compliance
Requirements
for
Sources
Subject
to
a
Work
Practice
Standard?
If
you
own
or
operate
an
affected
existing
shape
preheater,
an
existing
pitch
working
tank,
or
a
new
pitch
working
tank,
you
must
select
a
method
for
complying
with
the
applicable
work
practice
standard
and
provide
a
description
of
that
method
as
part
of
your
initial
notification,
as
required
by
40
CFR
63.9(
b)(
2).
For
affected
shape
preheaters,
if
you
choose
to
comply
with
the
work
practice
standard
by
cleaning
pitch
from
basket
or
container
surfaces,
you
must
describe
in
your
initial
notification
the
cleaning
method.
If
you
choose
to
comply
by
capturing
and
ducting
emissions
from
the
shape
preheater
to
a
control
device,
you
must
describe
the
design
(
e.
g.,
thermal
oxidizer
combustion
chamber
temperature
and
residence
time)
and
operation
of
that
control
device.
For
affected
existing
or
new
pitch
working
tanks,
you
must
describe,
in
your
initial
notification,
the
design
and
operation
of
the
control
device
to
which
the
emissions
from
the
working
tank
are
exhausted.
You
also
must
verify
that
the
performance
of
the
control
device
is
the
same
as,
or
is
equivalent
to,
the
control
device
that
is
used
to
control
organic
HAP
emissions
from
an
affected
defumer
or
coking
oven.
For
affected
new
or
existing
chromium
refractory
products
kilns
and
for
existing
clay
refractory
products
kilns,
you
must
indicate,
in
your
initial
notification,
the
type
of
fuel
used
in
those
kilns.

H.
What
Are
the
Continuous
Compliance
Requirements
for
Sources
Subject
to
Emission
Limits?
Today's
final
rule
requires
owners
and
operators
of
affected
sources
to
demonstrate
continuous
compliance
with
each
emission
limitation.
You
must
follow
the
requirements
in
your
OM&
M
plan
and
in
your
startup,
shutdown,
and
malfunction
plan
(
SSMP)
and
document
conformance
with
both
plans.
For
each
affected
source
equipped
with
an
add­
on
air
pollution
control
device
(
APCD),
you
must
inspect
each
system
at
least
once
each
calendar
year
and
record
the
results
of
each
inspection.
You
must
install,
operate,
and
maintain
each
required
CPMS
to
monitor
the
operating
parameters
established
during
your
initial
performance
test.
You
must
collect
all
data
while
the
process
is
operational.
You
will
have
to
operate
the
CPMS
at
all
times
when
the
process
is
operating.
You
must
also
conduct
proper
maintenance
of
the
CPMS,
including
inspections,
calibrations,
and
validation
checks.
You
must
repeat
any
required
performance
tests
at
least
every
5
years.
For
each
affected
source,
you
must
monitor
and
maintain
the
organic
HAP
processing
rate
below
the
level
established
during
the
most
recent
performance
test.
You
must
also
record
the
process
operating
temperature
hourly.
For
batch
process
sources,
you
must
record
the
cycle
time
for
each
batch
cycle.
If
you
decide
to
start
production
of
a
refractory
product
that
is
likely
to
have
an
organic
HAP
processing
rate
that
is
more
than
10
percent
greater
than
the
maximum
organic
HAP
processing
rate
established
during
the
most
recent
performance
test,
you
will
have
to
conduct
a
new
performance
test
for
that
product
and
establish
a
new
operating
limit
for
the
maximum
organic
HAP
processing
rate.
For
affected
continuous
sources
that
are
controlled
with
a
thermal
oxidizer,
you
must
maintain
the
3­
hour
block
average
combustion
chamber
temperature
at
or
above
the
combustion
chamber
temperature
operating
limit
established
during
the
most
recent
performance
test.
For
affected
continuous
sources
that
are
controlled
with
a
catalytic
oxidizer,
you
must
maintain
the
3­
hour
block
average
temperature
at
the
inlet
of
the
catalyst
bed
at
or
above
the
corresponding
temperature
operating
limit
established
during
the
most
recent
performance
test.
For
affected
batch
process
sources
that
are
controlled
with
a
thermal
oxidizer,
you
must
maintain
the
average
hourly
combustion
chamber
temperature
at
or
above
the
combustion
chamber
temperature
operating
limit
established
during
the
most
recent
performance
test.
To
document
compliance
with
these
operating
limits
for
thermal
or
catalytic
oxidizers,
you
must
measure
and
record
the
specified
average
hourly
temperatures.
You
must
also
report
any
average
hourly
control
device
operating
temperature
below
the
operating
limit

from
an
affected
source
using
process
modifications
or
an
add­
on
control
device
other
than
a
thermal
or

you
must
demonstrate
continuous
compliance
by
operating
a
THC
continuous
emission
monitoring
system
(
CEMS)
in
accordance
with
Procedure
1
of
40
CFR
part
60,
appendix
F.
For
new
clay
refractory
kilns
that
are
controlled
with
a
DLA,
you
must
monitor
continuously
the
pressure
drop
across
the
DLA.
You
also
must
check
the
limestone
feed
hopper
and
limestone
feeder
setting
daily
to
ensure
that
there
is
limestone
in
the
hopper,
the
limestone
is
free
flowing,
and
the
feed
rate
has
not
changed.
In
addition,
you
must
continue
using
the
same
source
of
limestone
as
was
used
during
the
most
recent
performance
test
and
maintain
records
that
demonstrate
that
the
source
of
limestone
has
not
changed.
For
new
clay
refractory
kilns
that
are
controlled
with
a
DIFF
or
DLS/
FF,
you
must
maintain
free­
flowing
lime
in
the
feed
hopper
or
silo
at
all
times.
You
also
must
maintain
the
lime
feeder
setting
at
or
above
the
level
established
during
the
most
recent
performance
test
and
record
the
feeder
setting
once
each
day.
You
must
initiate
corrective
action
within
1
hour
of
a
bag
leak
detection
system
alarm
and
complete
corrective
actions
according
to
your
OM&
M
plan.
For
kilns
that
are
controlled
with
a
wet
scrubber,
you
must
continuously
maintain
the
3­
hour
block
average
scrubber
pressure
drop,
scrubber
liquid
pH,
scrubber
liquid
flow
rate,
and
chemical
addition
rate
(
if
applicable)
at
or
above
the
corresponding
operating
limits
established
during
the
most
recent
performance
test.
Finally,
you
must
record
the
uncalcined
clay
processing
rate
for
all
affected
kilns.
If
you
operate
an
affected
continuous
kiln,
you
may
bypass
the
control
device
and
continue
operating
the
kiln
during
periods
of
scheduled
maintenance
on
the
kiln
control
device,
upon
approval
of
the
permitting
authority.
However,
you
must
request
prior
approval
from
the
permitting
authority
before
taking
the
control
device
offline.
You
must
minimize
HAP
emissions
during
the
period
when
the
control
device
is
offline.
You
must
also
minimize
the
time
period
when
the
control
device
is
offline.
Unlike
scheduled
maintenance,
a
malfunction
of
a
control

Summary
of
Major
Changes
Since
Proposal
A.
Emission
Limits
and
Work
Practice
Standards
For
thermal
process
sources
of
organic
HAP,
we
replaced
the
proposed
combustion
efficiency
limit
with
a
95
percent
THC
reduction
limit.
We
believe
that
the
95
percent
THC
reduction
limit
will
result
in
organic
HAP
emissions
reductions
that
are
comparable
to
the
reductions
that
would
have
been
achieved
through
the
proposed
99.8
percent
combustion
efficiency
limit.
Furthermore,
percentage
reduction
provides
a
better
measure
of
the
performance
of
a
control
device
in
reducing
organic
emissions
than
does
combustion
efficiency,
because
percentage
reduction
is
a
direct
measure
of
reductions
in
THC
emissions
across
the
control
device.
In
addition,
the
combination
of
the
proposed
THC
concentration
and
the
percentage
reduction
limits
allows
considerable
flexibility
in
how

and
operators

Rules
and
Regulations
choose
to
comply
with
today's
final
rule.
The
available
emission
data
for
the
refractory
products
manufacturing
industry
indicate
that
sources
that
are
controlled
to
levels
above
the
MACT
floor
(
i.
e.,
more
stringent
than
the
MACT
floor
control
level)
achieve
THC
emissions
reductions
of
at
least
95
percent,
and
sources
that
are
controlled
to
levels
below
the
MACT
floor
achieve
THC
emissions
reductions
that
are
less
than
95
percent.
Based
on
our
analysis
of
the
data,
we
concluded
that
a
95
percent
THC
reduction
represents
the
level
of
emissions
control
that
is
achieved
by
a
thermal
process
source
of
organic
HAP
that
is
controlled
to
the
MACT
floor
level.
Additional
information
on
our
analysis
of
the
available
THC
emission
reduction
data
is
provided
in
Docket
No.
OAR
 
2002
 
0088.
We
did
not
propose
a
percentage
THC
reduction
because
we
believed
that
testing
the
inlets
of
the
control
devices
used
on
thermal
process
sources
of
organic
HAP
was
not
feasible
for
most
sources.
However,
based
on
the
public
comments
received
on
the
proposed
rule,
we
believe
that
refractory
products
manufacturers
can
measure
THC
at
the
inlets
and
outlets
of
most
affected
sources.
Furthermore,
those
facilities
that
cannot
obtain
inlet
and
outlet
measurements
still
have
the
option
of
complying
with
the
20
ppmvd
THC
emission
limit.
For
the
proposed
rule,
we
developed
HF
and
HCl
emission
limits
based
on
the
emission
levels
that
could
be
achieved
by
the
best­
controlled
kiln
in
the
brick
and
structural
clay
products
industry.
Since
proposal,
we
have
obtained
additional
information
on
the
types
of
emission
controls
used
in
the
brick
and
structural
clay
products
industry
to
reduce
emissions
of
HF
and
HCl
from
kilns.
Based
on
that
information,
we
have
concluded
that
the
best­
controlled
similar
source
for
clay
refractory
products
kilns
is
a
small
brick
kiln
that
is
controlled
with
a
DLA.
A
small
brick
kiln
is
a
kiln
with
a
production
capacity
of
less
than
9.1
Mg
per
hour
(
Mg/
hr)
(
10
tons
per
hour
(
tons/
hr)).
The
data
indicate
that
a
DLA
can
achieve
HF
emissions
reductions
of
90
percent
and
HCl
emissions
reductions
of
30
percent.
We
used
those
emissions
reductions
to
develop
the
HF
and
HCl
emission
limits
specified
in
the
final
rule.
The
revised
emission
limits
for
HF
are
a
90
percent
reduction
or
0.019
kg/
Mg
(
0.038
lb/
ton)
of
uncalcined
clay
processed.
For
HCl,
the
revised
emission
limits
are
a
30
percent
reduction
or
0.091
kg/
Mg
(
0.18
lb/
ton)
of
uncalcined
clay
processed.
For
proposal,
we
based
the
HF
and
HCl
emission
limits
for
new
clay
refractory
products
kilns
on
emission
data
for
a
brick
kiln
that
was
controlled
with
a
DLS/
FF.
When
we
developed
those
proposed
emission
limits,
we
made
no
distinction
between
kiln
size
and
control
options.
However,
a
review
of
the
emission
data
for
controlled
brick
kilns
indicates
that
kiln
size
must
be
considered
when
determining
feasible
control
options
for
reducing
emissions
of
HF
and
HCl.
For
brick
kilns
with
production
capacities
of
9.1
Mg/
hr
(
10
tons/
hr)
or
greater
(
i.
e.,
large
kilns),
several
control
devices
have
been
demonstrated
to
be
highly
effective
in
reducing
HF
and
HCl
emissions.
Those
controls
include
DLS/
FF,
DIFF,
and
wet
scrubbers.
However,
for
brick
kilns
that
are
designed
with
production
capacities
below
9.1
Mg/
hr
(
10
tons/
hr),
only
the
DLA
has
been
demonstrated
to
be
a
feasible
control
option
for
HF
and
HCl.
With
DLS/
FF,
DIFF,
and
wet
scrubbers,
it
is
necessary
to
maintain
minimum
exhaust
gas
flow
rates
for
effective
HF
and
HCl
removal,
and
those
minimum
exhaust
flow
rates
are
significantly
greater
than
the
flow
rates
characteristic
of
small
brick
kilns.
On
the
other
hand,
the
performance
of
the
DLA
is
unaffected
by
exhaust
gas
flow
rates
through
the
system,
and
DLA
have
been
used
on
small
brick
kilns.
Consequently,
we
have
concluded
that
the
bestcontrolled
small
brick
kiln
is
equipped
with
a
DLA.
We
have
also
concluded
that
clay
refractory
products
kilns
are
similar
to
small
brick
kilns
because
90
percent
of
the
clay
refractory
products
tunnel
kilns
currently
in
use
were
designed
to
operate
at
4.5
Mg/
hr
(
5
tons/
hr)
or
less,
and
there
are
no
clay
refractory
products
kilns
that
operate
with
production
rates
greater
than
8.2
Mg/
hr
(
9
tons/
hr).
For
existing
clay
and
chromium
refractory
products
kilns,
we
are
still
requiring
limits
on
the
types
of
fuels
that
can
be
used
in
affected
kilns.
However,
we
have
also
included
a
provision
for
the
affected
facilities
to
use
alternative
fuels
during
specified
times
of
natural
gas
curtailment
and
during
other
times
when
natural
gas
is
unavailable.
To
comply
with
this
provision,
owners
or
operators
of
affected
kilns
must
notify
the
permitting
authority
within
48
hours
following
the
declaration
of
such
an
emergency
or
the
interruption
of
the
natural
gas
supply.
In
addition,
within
10
working
days
after
the
facility
terminates
the
use
of
the
alternative
fuel,
the
final
rule
requires
submittal
of
a
report
that
details
the
dates
of
alternative
fuel
usage
and
the
amount
of
alternative
fuel
used.
B.
Compliance
Testing
For
batch
process
sources,
we
have
reduced
the
minimum
number
of
compliance
test
runs
from
three
to
two.
We
believe
that
two
test
runs
are
adequate
for
characterizing
emissions
from
batch
process
sources.
Although
we
are
still
requiring
a
minimum
of
three
1­
hour
test
runs
for
continuous
sources,
we
believe
that
it
is
unnecessary
to
test
batch
process
sources
for
three
runs.
Under
the
final
rule,
each
test
run
on
a
batch
process
source
will
last
at
least
3
hours,
and
in
most
cases
a
test
run
will
last
considerably
longer
(
i.
e.,
in
excess
of
10
hours).
Thus,
even
with
the
reduced
number
of
test
runs,
an
emission
test
on
a
batch
process
source
will
still
require
a
much
longer
test
period
than
a
test
on
a
continuous
process
source.
Because
of
the
extensive
duration
of
each
test
run,
we
believe
that
a
second
test
run
is
adequate
for
corroborating
the
results
of
the
initial
test
run,
and
a
third
test
run
is
unnecessary.
Many
batch
process
refractory
products
are
specialty
items
that
are
produced
infrequently.
Because
we
are
requiring
each
test
run
to
be
conducted
over
a
separate
batch
process
cycle,
it
may
not
be
practical,
and
it
may
disrupt
production
of
other
products,
to
require
testing
over
separate
cycles.
In
some
cases,
conducting
the
compliance
test
over
multiple
process
cycles
could
require
a
testing
period
of
weeks
or
months,
thereby
preventing
the
use
of
the
batch
process
source
for
manufacturing
other
refractory
products.
For
this
same
reason,
we
have
included
in
today's
final
rule
a
provision
for
allowing
owners
and
operators
to
conduct
both
test
runs
simultaneously
over
a
single
batch
process
cycle
using
paired
sampling
trains,
under
certain
conditions.
Rather
than
basing
compliance
on
a
rolling
3­
hour
average,
today's
final
rule
requires
compliance
for
batch
process
sources
to
be
based
on
emissions
over
the
3­
hour
peak
emissions
period.
For
situations
in
which
a
facility
begins
production
of
a
new
product
that
constitutes
a
slight
increase
in
the
maximum
organic
HAP
processing
rate,
we
are
no
longer
requiring
a
repeat
performance
test.
Specifically,
if
the
organic
HAP
processing
rate
for
the
new
product
is
no
more
than
10
percent
greater
than
the
organic
HAP
processing
rate
established
during
the
most
recent
compliance
test,
a
repeat
performance
test
is
not
required.
We
believe
this
change
is
appropriate
for
several
reasons.
The
HAP
content
of
some
raw
materials
used
in
refractory
products
manufacturing
can
vary
slightly
from
shipment
to
shipment,
and
those

variations
may
be
beyond
the
control
of
the
user.
The
net
increase
in
controlled
emissions
from
a
source
that
uses
a
material
with
a
slightly
higher
HAP
content
would
most
likely
be
within
the
measurement
error
of
the
test
method.
On
the
other
hand,
if
the
organic
HAP
processing
rate
for
the
new
product
is
more
than
10
percent
greater
than
the
operating
limit
for
the
maximum
organic
HAP
processing
rate,
a
new
compliance
test
must
be
performed.

C.
Control
Device
Monitoring
and
Operation
In
the
final
rule,
we
have
added
the
requirement
that
owners
or
operators
of
affected
sources
that
are
controlled
with
a
catalytic
oxidizer
must
have
the
catalyst
activity
level
checked
at
least
every
12
months
and
take
any
necessary
corrective
action,
such
as
replacing
the
catalyst,
to
ensure
that
the
catalyst
is
performing
as
designed.
We
continue
to
require
catalyst
bed
inlet
temperature
monitoring.
However,
we
believe
this
additional
requirement
is
needed
because,
unlike
thermal
oxidizers,
catalytic
oxidizer
performance
cannot
be
ensured
simply
by
monitoring
the
operating
temperature.
Catalyst
beds
can
become
poisoned
and
rendered
ineffective
without
any
apparent
change
in
operation.
Requiring
an
annual
check
of
catalyst
activity
will
help
to
identify
catalyst
poisoning
and
other
potential
performance
problems
before
they
become
serious.
An
activity
level
check
can
consist
of
passing
an
organic
compound
of
known
concentration
through
a
sample
of
the
catalyst,
measuring
the
percentage
reduction
of
the
compound
across
the
catalyst
sample,
and
comparing
that
percentage
reduction
to
the
percentage
reduction
for
a
fresh
sample
of
the
same
type
of
catalyst.
We
have
made
several
changes
to
the
monitoring
requirements
for
new
clay
refractory
products
kilns.
We
have
added
monitoring
requirements
for
kilns
controlled
with
a
DLA.
Specifically,
owners
or
operators
of
affected
kilns
are
required
to
monitor
continuously
the
pressure
drop
across
the
DLA,
check
the
limestone
feed
hopper
daily
to
ensure
that
limestone
is
free
flowing,
check
the
limestone
feeder
setting
daily,
use
the
same
source
of
limestone
as
was
used
during
the
most
recent
performance
test,
and
maintain
records
that
demonstrate
that
the
source
of
limestone
has
not
changed.
We
have
eliminated
the
requirement
to
monitor
the
fabric
filter
inlet
temperature
for
affected
clay
refractory
kilns
that
are
controlled
with
a
DIFF
or
a
DLS/
FF.
Finally,
we
have
eliminated
the
requirement
to
monitor
the
water
injection
rate
for
kilns
that
are
controlled
with
a
DLS/
FF.
We
have
also
included
in
the
final
rule
a
provision
to
allow
owners
and
operators
of
affected
continuous
process
kilns
to
bypass
the
control
device
and
continue
operating
the
kilns
during
periods
when
the
control
device
is
offline
for
scheduled
maintenance.
However,
the
owner
or
operator
must
request
approval
from
the
permitting
authority
before
taking
the
control
device
out
of
service.
The
owner
or
operator
must
minimize
the
time
periods
during
which
the
control
device
is
offline
and
must
also
minimize
HAP
emissions
from
the
affected
sources
during
these
periods.
The
owner
or
operator
must
also
maintain
records
of
all
maintenance
activities
and
the
time
when
the
control
device
was
offline.
In
addition,
procedures
for
minimizing
HAP
emissions
during
periods
when
the
control
device
is
offline
must
be
incorporated
into
the
OM&
M
plan
for
the
kiln.

D.

We
have
modified
the
definitions
of

and
have
added

Summary
of
Responses
to
Major
Comments
A.
MACT
Floors
Comment:
One
commenter
pointed
out
that
more
than
30
refractory
products
manufacturing
plants
have
closed
permanently
over
the
past
3
years.
The
commenter
stated
that
the
MACT
floors
used
to
develop
the
proposed
rule
are
based
on
data
that
no
longer
reflect
the
current
status
of
the
industry.
The
commenter
believes
that
it
is
improper
for
us
to
use
the
old
data
while
the
industry
is
in
the
process
of
realignment.
In
response
to
a
request
by
us,
the
same
commenter
provided
a
list
of
35
plants
that
have
closed
recently.
Response:
We
have
reviewed
the
list
of
35
recently
closed
plants
provided
by
the
commenter
and
among
those
plants,
we
considered
only
one,
the
North
American
Refractories
plant
in
Womelsdorf,
PA,
to
be
a
major
or
synthetic
area
source
of
organic
HAP.
However,
we
were
aware
of
the
impending
closure
of
that
particular
facility
before
we
determined
the
MACT
floors
for
the
proposed
rule,
and
we
did
not
include
affected
sources
at
that
plant
in
our
MACT
floor
analyses.
Because
we
based
our
determination
of
the
MACT
floors
for
sources
of
organic
HAP
emissions
only
on
major
and
synthetic
area
sources
and
none
of
those
plants
has
closed,
the
closing
of
the
35
plants
has
no
impact
on
the
MACT
floor
analyses
used
to
develop
the
proposed
or
final
NESHAP.

B.
Emission
Limits
Comment:
One
commenter
stated
that
the
proposed
combustion
efficiency
limit
has
no
relationship
to
the
MACT
floors
for
thermal
process
sources
of
organic
HAP.
He
believes
that
the
proposed
combustion
efficiency
limit
is
an
arbitrary
limit
based
on
theoretical
calculations
and
is
not
supported
by
the
data.
The
commenter
also
stated
that
we
cannot
identify
any
plants
that
have
met
a
99.8
percent
combustion
efficiency.
He
believes
that
the
proposed
combustion
efficiency
limit
cannot
be
met
by
existing
sources;
consequently,
the
stringency
of
the
99.8
percent
combustion
efficiency
limit
will
force
all
affected
facilities
to
meet
the
alternative
proposed
limit
on
THC.
The
same
commenter
stated
that
he
has
been
informed
by
control
device
vendors
that
sources
would
have
to
operate
well
above
the
MACT
floor
level
of
control
to
meet
a
99.8
percent
combustion
efficiency
limit.
Another
commenter
agreed
that
the
combustion
efficiency
limit
will
force
the
industry
to
meet
the
alternative
THC
limit.
Both
commenters
also
stated
that
most
of
the
thermal
oxidizers
currently
used
in
the
refractory
products
manufacturing
industry
would
not
be
able
to
meet
the
outlet
exhaust
gas
limitation
of
3
percent
carbon
dioxide
that
is
a
prerequisite
for
choosing
the
combustion
efficiency
limit
compliance
option.
One
commenter
added
that
sources
controlled
with
catalytic
oxidizers
would
be
unable
to
meet
the
99.8
percent
combustion
efficiency
limit.
The
same
two
commenters
also
commented
on
the
appropriateness
of
a
combustion
efficiency
limit.
One
of
the
commenters
stated
that
he
contacted
thermal
oxidizer
vendors
and
a
trade
association
that
represents
control
device
manufacturers
and
vendors,
all
of
whom
stated
that
they
were
unfamiliar
with
combustion
efficiency.
They
indicated
that
thermal
oxidizer
performance
guarantees
invariably
are
written
in
terms
of
destruction
and
removal
efficiency
(
DRE).
The
other
commenter
concurred
that
vendors
offer
performance
guarantees
in
terms
of
DRE
and
not
in
terms
of
combustion

efficiency.
The
commenter
stated
that
he
believes
that
there
is
no
known
correlation
between
combustion
efficiency
and
DRE,
and
he
noted
that
we
also
have
made
that
point
on
several
occasions.
Finally,
the
same
commenter
stated
that
the
Pennsylvania
Department
of
Environmental
Resources
informed
him
that
they
do
not
incorporate
emission
limits
for
combustion
efficiency
in
their
operating
permits.
Response:
After
reviewing
these
comments,
we
have
decided
not
to
include
the
combustion
efficiency
limit
in
the
final
rule.
Although
we
still
maintain
that
the
proposed
combustion
efficiency
limit
could
be
achieved
by
refractory
products
manufacturing
sources
that
are
controlled
to
the
MACT
floor
level,
we
acknowledge
that
refractory
products
manufacturing
industry
personnel,
vendors,
emission
testing
contractors,
and
permitting
agency
personnel
may
not
be
familiar
with
the
concept
of
using
combustion
efficiency
as
a
measure
of
the
control
of
organic
pollutants.
In
addition,
combustion
efficiency
is
essentially
an
indicator
of
control
device
performance
rather
than
a
direct
measure
of
emissions
reductions
or
control.
There
are
alternatives
to
a
combustion
efficiency
limit
that
provide
reliable
measures
of
control
device
performance
and
emissions
reductions,
and
we
have
included
one
such
alternative,
a
percentage
THC
reduction,
in
the
final
rule.
We
believe
that
a
THC
percentage
reduction
is
a
more
appropriate
format
for
an
emission
limit
than
is
combustion
efficiency
because
percentage
reduction
is
a
measure
of
emissions
reductions
and
can
be
related
directly
to
the
MACT
floor
for
thermal
process
sources
of
organic
HAP.
Comment:
Two
commenters
recommended
that
we
consider
a
limit
on
DRE
instead
of
a
combustion
efficiency
limit.
One
of
the
commenters
stated
that
control
device
vendors
typically
offer
performance
guarantees
in
terms
of
a
DRE
limit,
coupled
with
an
outlet
concentration
limit
for
lowemitting
sources.
The
other
commenter
stated
that
an
alternative
limit
of
95
percent
DRE
for
THC
would
be
appropriate
for
the
refractory
products
manufacturing
industry.
One
of
the
commenters
evaluated
two
catalytic
oxidizers
used
at
his
facility.
He
concluded
that
the
oxidizers
would
be
unable
to
meet
a
99.8
percent
combustion
efficiency
limit
or
the
proposed
THC
limit
of
20
ppmvd,
corrected
to
18
percent
oxygen.
However,
he
believes
that
both
of
the
catalytic
oxidizers
he
evaluated
could
achieve
a
DRE
of
approximately
95
percent.
The
same
commenter
also
disagreed
with
our
statement
that
a
DRE
limit
would
be
problematic
due
to
the
lack
of
access
to
control
device
inlets
for
emission
testing
on
most
affected
sources.
He
stated
that
facilities
can
retrofit
existing
sources
to
allow
for
control
device
inlet
testing.
Response:
We
agree
with
the
commenters
that
a
DRE
limit,
which
generally
is
referred
to
as
a
percentage
reduction
limit
in
NESHAP,
would
be
appropriate
for
the
refractory
products
manufacturing
industry.
Consequently,
we
have
decided
to
incorporate
an
emission
limit
of
95
percent
THC
reduction
in
today's
final
rule
as
an
alternative
to
the
THC
emission
concentration
limit.
We
believe
that
percentage
reduction
provides
the
best
measure
of
the
performance
of
a
control
device
in
reducing
organic
emissions.
Because
percentage
reduction
is
a
direct
measure
of
emissions
reductions,
we
also
believe
it
is
more
consistent
with
the
MACT
floor
concept
than
is
the
proposed
combustion
efficiency
limit.
Unlike
combustion
efficiency,
we
have
THC
percentage
reduction
data
for
several
refractory
products
manufacturing
sources.
By
comparing
those
data
to
the
MACT
floor
levels
established
by
today's
rule
(
see
Docket
No.
OAR
 
2002
 
0088),
we
were
able
to
conclude
that
the
95
percent
THC
reduction
limit
that
we
have
incorporated
into
the
final
rule
is
representative
of
the
emissions
reductions
that
sources
controlled
to
the
MACT
floor
level
should
be
able
to
achieve
on
a
consistent
basis.
Comment:
One
commenter
commented
on
the
fact
that
the
same
combustion
efficiency
limit
was
proposed
for
several
different
types
of
thermal
process
sources,
such
as
periodic
kilns,
tunnel
kilns,
dryers,
and
coking
ovens.
He
believes
that
differences
in
the
operation
of
these
various
types
of
sources
warrant
different
emission
limits.
Response:
We
considered
establishing
separate
emission
limits
for
each
type
of
thermal
process
source
of
organic
HAP.
However,
the
MACT
floors
for
both
existing
and
new
sources
are
based
on
thermal
oxidizer
control,
and
the
MACT
floor
level
thermal
oxidizer
operating
temperatures
and
residence
times
are
similar
for
the
various
types
of
thermal
process
sources.
These
thermal
oxidizers
represent
relatively
high
levels
of
control,
and
based
on
their
design
and
operating
parameters,
we
would
not
expect
there
to
be
significant
differences
in
performance
levels
among
them.
Furthermore,
when
the
theoretical
performance
levels
of
these
thermal
oxidizers
are
compared,
the
Arrhenius
equation
predicts
that
all
of
them
would
achieve
essentially
complete
control
of
organic
emissions.
The
available
valid
emission
test
data
on
organic
emissions
from
controlled
thermal
process
sources
of
organic
HAP
also
do
not
support
making
such
distinctions
in
emission
limits.
Consequently,
we
decided
to
establish
the
same
emission
limits
for
all
types
of
thermal
process
sources
of
organic
HAP
subject
to
today's
final
rule.
Comment:
Two
commenters
stated
that
the
available
emission
data
do
not
support
the
proposed
THC
limit
of
20
ppmvd.
The
commenters
believe
that
the
data
support
an
emission
limit
of
30
ppmvd
THC,
based
on
the
average
THC
emission
concentration
for
the
available
test
data
on
controlled
kilns.
Response:
To
determine
the
MACT
floors
and
the
corresponding
emission
limits
for
existing
sources,
we
first
must
consider
the
number
of
sources
in
operation
at
major
and
synthetic
area
source
facilities.
In
the
case
of
kilns
that
are
used
to
fire
refractory
products
that
contain
organic
HAP,
there
are
fewer
than
30
kilns
that
can
be
considered
in
establishing
the
MACT
floor.
Under
section
112(
d)(
3)
of
the
CAA,
we
must
select
the
average
or
median
of
the
bestperforming
five
sources.
In
this
case,
the
MACT
floor
for
kilns
corresponds
to
the
third­
best
performing
kiln.
To
rank
kilns
in
terms
of
their
performance
in
controlling
organic
HAP
emissions,
we
needed
emissions
data
for
each
of
the
best­
performing
kilns.
However,
we
did
not
have
data
on
emissions
of
organic
HAP
(
or
THC
as
a
surrogate
for
organic
HAP)
for
any
of
the
best­
controlled
kilns.
The
specific
kilns
referenced
by
the
commenters
are
not
among
the
best­
performing
kilns
in
operation
at
major
or
synthetic
area
source
facilities,
so
it
would
be
contrary
to
the
requirements
of
the
CAA
to
average
emission
data
for
those
kilns,
as
the
commenters
suggest,
because
such
an
average
would
include
data
from
sources
that
are
clearly
not
among
the
top
five
best­
performing
kilns
located
at
major
or
synthetic
area
source
facilities.
An
alternative
approach
to
determining
MACT
floors
by
ranking
sources
according
to
demonstrated
emissions
reductions
is
to
rank
the
sources
based
on
the
likely
performance
level
of
the
control
devices
in
place.
We
used
this
alternative
approach
to
determine
the
MACT
floors
for
organic
HAP
emissions
from
thermal
process
sources.
Using
the
Arrhenius
equation,
we
ranked
all
of
the
controlled
kilns
located
at
major
or
synthetic
area
source
facilities
and
selected
the
third­
best
kiln
as
the
MACT
floor.
However,
to
develop
the
20
ppmvd
THC
emission
limit,
we
did
consider
all
of
the
available
data,

After
considering
the

of
the

for
those

and
the
likely
variations
in
emission

we
concluded
that

support
a

Comment:
One
commenter
stated
that
Congress
intended
MACT
standards
to
be
industry­
specific,
and
he
objected
to
the
use
of
data
for
the
brick
and
structural
clay
products
industry
to
establish
emission
limits
for
HF
and
HCl
from
clay
refractory
products
kilns.
The
commenter
stated
that
it
is
inappropriate
to
use
data
from
another
industry
to
develop
emission
limits
for
the
refractory
products
manufacturing
industry.
Response:
Section
112(
d)
of
the
CAA
requires
us
to
establish
emission
limits
for
new
sources
based
on
the
performance
of
the
best­
controlled
similar
source.
The
CAA
does
not
specify
that
the
similar
source
must
be
within
the
same
source
category.
To
the
contrary,
our
interpretation
of
section
112(
d)
is
that
we
are
obligated
to
consider
similar
sources
from
other
source
categories
in
determining
the
best­
controlled
similar
source
for
establishing
MACT
for
new
sources.
For
clay
refractory
products
kilns,
we
concluded
that
the
best­
controlled
similar
sources
are
found
in
the
brick
and
structural
clay
products
industry.
We
believe
that
brick
kilns
are
similar
to
clay
refractory
products
kilns
for
several
reasons:
(
1)
Most
clay
refractory
products
are
fired
in
tunnel
kilns,
as
is
the
case
for
brick
manufacturing;
(
2)
in
both
industries,
tunnel
kilns
are
designed
to
have
three
temperature
zones,
a
preheating
or
drying
zone,
a
firing
zone,
and
a
cooling
zone;
(
3)
in
both
industries,
unfired
shapes
(
bricks
or
refractories)
are
loaded
onto
rail
cars
and
transported
through
each
successive
temperature
zone
through
a
series
of
timed
pushes;
(
4)
both
clay
refractory
kilns
and
brick
kilns
typically
operate
at
peak
temperatures
of
approximately
2000
°
F;
(
5)
firing
times
in
clay
refractory
and
brick
kilns
are
similar;
(
6)
the
raw
materials
used
in
producing
bricks
(
primarily
common
clay
and
shale,
but
also
fire
clay)
and
clay
refractories
(
primarily
fire
clay)
are
similar;
and
(
7)
at
least
one
refractory
products
manufacturer
fires
both
clay
refractory
products
and
brick
and
structural
clay
products
in
the
same
kilns.
The
HF
and
HCl
controls
currently
used
in
the
brick
and
structural
clay
products
industry
are
a
function
of
kiln
size
(
i.
e.,
production
rate).
Kilns
with
production
capacities
of
less
than
9.1
Mg/
hr
(
10
tons/
hr)
are
classified
as
small
kilns,
and
those
with
production
capacities
of
at
least
9.1
Mg/
hr
(
10
tons/
hr)
are
classified
as
large
kilns.
For
small
brick
kilns,
the
best­
performing
source
is
a
kiln
controlled
with
a
DLA.
For
large
kilns,
the
best­
performing
sources
are
those
controlled
with
either
a
DIFF,
DLS/
FF,
or
wet
scrubber.
Although
DIFF,
DLS/
FF,
and
wet
scrubbers
generally
are
more
effective
than
DLA
in
reducing
emissions
of
HF
and
HCl,
large
kiln
controls
require
minimum
exhaust
gas
flow
rates
that
are
significantly
higher
than
the
flow
rates
characteristic
of
small
kilns.
Consequently,
the
DLA
is
the
only
device
that
has
been
demonstrated
to
be
feasible
for
controlling
HF
and
HCl
emissions
from
small
brick
kilns.
Using
the
same
size
classification
system,
the
clay
refractory
products
kilns
currently
in
operation
would
all
be
classified
as
small
kilns.
All
operate
at
less
than
9.1
Mg/
hr
(
10
tons/
hr),
and
90
percent
operate
at
no
more
than
4.5
Mg/
hr
(
5
tons/
hr).
Because
of
the
similarities
in
design
and
operation
discussed
in
the
previous
paragraph,
and
taking
into
account
kiln
size,
we
have
concluded
that
small
brick
kilns
and
clay
refractory
products
kilns
are
similar
sources.
In
the
final
rule,
we
are
incorporating
HF
and
HCl
emission
limits
based
on
the
performance
of
DLA­
controlled
brick
kilns.
Comment:
One
commenter
expressed
concern
with
how
we
used
data
for
the
brick
and
structural
clay
products
industry
to
develop
emission
limits
for
new
clay
refractory
products
kilns.
He
stated
that
we
used
the
same
data
to
propose
more
stringent
HF
and
HCl
limits
for
new
clay
refractory
products
kilns
than
were
proposed
for
new
brick
and
structural
clay
products
kilns
under
the
proposed
Brick
and
Structural
Clay
Products
NESHAP
(
67
FR
47894,
July
22,
2002).
The
proposed
HF
emission
limit
for
new
brick
and
structural
clay
products
kilns
is
0.014
kg/
Mg
(
0.027
lb/
ton),
whereas
the
proposed
HF
limit
for
new
clay
refractory
products
kilns
is
0.001
kg/
Mg
(
0.002
lb/
ton).
In
addition,
the
proposed
HCl
emission
limit
for
new
brick
and
structural
clay
products
kilns
is
0.019
kg/
Mg
(
0.037
lb/
ton),
whereas
the
proposed
HCl
limit
for
new
clay
refractory
products
kilns
is
0.0025
kg/
Mg
(
0.005
lb/
ton).
Response:
In
selecting
the
proposed
HF
and
HCl
emission
limits
for
new
clay
refractory
products
kilns,
we
reviewed
the
available
emission
data
from
the
brick
and
structural
clay
products
industry
and
selected
the
single
best­
performing
similar
source,
which
was
an
individual
brick
kiln
controlled
with
a
DLS/
FF.
To
select
the
HF
and
HCl
emission
limits
for
brick
kilns
in
the
proposed
Brick
and
Structural
Clay
Products
NESHAP,
we
used
a
different
approach
based
on
the
overall
performance
of
the
available
control
technologies.
We
reviewed
the
available
data
and
concluded
that
the
three
best­
performing
control
technologies
(
DLS/
FF,
DIFF,
and
wet
scrubbers)
are
essentially
comparable
in
terms
of
reducing
HF
and
HCl
emissions.
We
also
considered
the
variability
in
the
data
and
selected
the
percentage
reductions
that
we
believe
all
three
technologies
can
achieve
on
a
continuous
basis
according
to
the
available
test
data.
We
used
those
percentage
reductions,
which
were
95
percent
for
HF
and
90
percent
for
HCl,
to
derive
the
proposed
production­
based
emission
limits
from
the
emission
factors
for
uncontrolled
HF
and
HCl
from
brick
kilns.
Those
productionbased
emission
limits
were
0.014
kg/
Mg
(
0.027
lb/
ton)
for
HF
and
0.019
kg/
Mg
(
0.037
lb/
ton)
for
HCl.
After
reconsidering
both
approaches
for
selecting
emission
limits,
we
have
concluded
that
the
technology­
based
approach
that
we
used
to
develop
the
emission
limits
for
the
proposed
Brick
and
Structural
Clay
Products
NESHAP
is
the
appropriate
method
for
establishing
HF
and
HCl
emission
limits
for
new
clay
refractory
products
kilns.
In
the
proposed
Brick
and
Structural
Clay
Products
NESHAP,
we
also
subcategorized
according
to
kiln
size
by
differentiating
between
large
kilns
(
i.
e.,
those
with
production
capacities
of
9.1
Mg/
hr
(
10
tons/
hr)
or
greater)
and
small
kilns
(
i.
e.,
those
with
production
capacities
that
are
less
than
9.1
Mg/
hr
(
10
tons/
hr)).
For
today's
final
rule,
we
have
incorporated
this
same
size
classification
system
into
our
determination
of
the
emission
limits
for
new
clay
refractory
products
kilns.
We
have
concluded
that
small
brick
kilns
are
similar
to
clay
refractory
products
kilns
and
that
the
best­
controlled
similar
source
for
clay
refractory
products
kilns
is
a
small
brick
kiln
controlled
with
a
DLA.
Although
there
are
other
technologies
that
perform
well
in
controlling
HF
and
HCl
emissions
from
brick
kilns
(
i.
e.,
DLS/
FF,
DIFF,
and
wet
scrubbers),
those
control
devices
have
been
used
only
on
large
brick
kilns.
On
the
other
hand,
DLA
are
currently
in
use
on
both
large
and
small
brick
kilns.
The
available
data
indicates
that
a
DLA
can
achieve
emissions
reductions
of
90
percent
HF
and
30
percent
HCl
on
a
consistent
basis.
We
have
applied
these
emissions
reductions
to
HF
and
HCl
data
from
uncontrolled
clay
refractory
products
kilns
and
are
incorporating
into
today's
final
rule

questioned
the
need

He
stated
that
chromium
compounds
should
be

of

He
noted
that
the

decreased
significantly
in

and
that

He
also
pointed

down.
Response:
As
noted

oxide,
is
a
principal
ingredient
in
the
formulation
of
many
refractory
products
and
is
emitted
from
kilns
that
fire
chromium
refractory
products.
Some
of
the
chromium
is
emitted
in
the
hexavalent
form,
which
is
a
known
human
carcinogen.
Under
section
112(
d)
of
the
CAA,
we
are
required
to
establish
emission
standards
that
are
at
least
as
stringent
as
the
MACT
floor
for
all
listed
HAP
that
are
emitted
from
major
sources.
Consequently,
regardless
of
the
trend
in
chromium
refractory
production,
we
are
required
to
establish
emission
limits
based
on
the
MACT
floor
level
of
control,
which
for
chromium
refractory
products
kilns
is
the
work
practice
of
firing
kilns
with
natural
gas
or
the
equivalent.
Comment:
One
commenter
opposed
the
provision
in
the
proposed
rule
that
limits
the
types
of
fuels
used
to
fire
clay
and
chromium
refractory
products
kilns.
He
stated
that
many
refractory
products
manufacturing
industry
kilns
are
designed
to
use
fuels
other
than
natural
gas,
such
as
fuel
oil,
propane,
and
pulverized
coal.
The
need
to
use
these
alternative
fuels
is
of
particular
importance
during
natural
gas
shortages
or
price
increases.
He
pointed
out
that
during
natural
gas
shortages,
residential
users
receive
priority
over
industrial
users
of
natural
gas.
He
believes
that
prohibiting
the
use
of
these
alternative
fuels
could
adversely
impact
the
viability
of
some
refractory
products
manufacturing
operations.
Response:
We
agree
with
the
commenter
that
the
Refractory
Products
Manufacturing
NESHAP
should
include
appropriate
provisions
for
the
use
of
alternative
fuels
during
specified
times
of
natural
gas
curtailment
and
other
situations
when
natural
gas
is
unavailable.
We
consider
such
situations
analogous
to
malfunctions,
which
are
addressed
in
40
CFR
63.6.
Just
as
an
exceedance
of
emission
limits
during
a
malfunction
is
not
considered
a
violation,
as
indicated
in
40
CFR
63.6(
f)(
1)
and
(
h)(
1),
we
believe
that
using
other
fuels
during
periods
when
natural
gas
is
unavailable
should
also
not
be
considered
a
violation
of
the
work
practice
standard
for
clay
and
chromium
refractory
products
kilns.
We
also
note
that
operating
permits
for
existing
refractory
products
manufacturing
facilities
generally
allow
the
use
of
fuel
oil
and
other
substitutes
for
natural
gas
in
some
situations.
Thus,
the
MACT
floor
for
existing
clay
and
chromium
refractory
products
kilns
is
the
use
of
natural
gas
or
equivalent
fuel
except
during
periods
when
natural
gas
is
unavailable.
In
the
final
rule,
we
are
allowing
owners
and
operators
of
affected
chromium
and
clay
refractory
products
kilns
to
use
alternative
fuels
during
periods
when
natural
gas
in
unavailable
due
to
a
supply
curtailment
or
other
factors.
However,
we
do
not
believe
that
natural
gas
price
increases
constitute
such
a
situation,
and
the
final
rule
makes
it
clear
that
natural
gas
prices
cannot
be
considered
the
basis
for
a
MACT
floor
that
requires
using
an
alternative
fuel.
The
final
rule
also
requires
owners
or
operators
to
notify
the
regulatory
authority
within
48
hours
after
the
declaration
of
natural
gas
curtailment
or
the
interruption
of
natural
gas
supply.
In
addition,
the
owner
or
operator
must
submit
a
report
that
details
the
dates
of
alternative
fuel
usage
and
the
amount
of
alternative
fuel
used
within
10
working
days
after
the
facility
terminates
the
use
of
the
alternative
fuel.

C.
Compliance
Testing
and
Monitoring
Comment:
One
commenter
stated
that
the
requirement
to
test
batch
process
sources
during
three
separate
process
cycles
is
redundant,
unnecessary,
and
burdensome.
He
believes
that
it
would
be
adequate
to
test
one
process
cycle.
He
pointed
out
that
there
are
significant
variations
in
product
mixes
and
raw
materials
from
cycle
to
cycle,
and
that
while
it
could
be
argued
that
testing
one
cycle
is
adequate,
it
could
also
be
argued
that
testing
ten
cycles
is
inadequate
for
characterizing
emissions.
He
noted
that
testing
during
cool­
down
periods,
in
particular,
is
unnecessary.
Response:
We
agree
with
the
commenter
that
testing
batch
process
sources
for
three
cycles
of
a
``
worstcase
batch
may
be
unnecessary
to
characterize
emissions
and
control
device
performance.
Under
the
final
rule,
we
are
requiring
owners
and
operators
of
affected
batch
process
sources
to
perform
at
least
two
test
runs
on
each
of
two
separate
process
cycles.
We
believe
that
a
second
test
run
is
necessary
to
corroborate
the
results
of
the
initial
test
run.
However,
we
also
note
that
each
test
run
on
a
batch
process
source
must
be
a
minimum
of
3
hours
in
duration,
and
for
many
batch
process
sources,
the
minimum
test
run
duration
is
likely
to
be
in
excess
of
10
hours.
Thus,
even
requiring
only
two
test
runs
will
necessitate
at
least
20
hours
of
testing
for
such
sources,
and
we
consider
a
test
of
that
duration
to
be
adequate
for
demonstrating
compliance
with
emission
limits.
We
also
note
that
other
NESHAP,
such
as
subparts
U,
JJJ,
OOO,
and
UUUU
to
40
CFR
part
63,
do
not
require
batch
process
sources
to
be
tested
for
three
test
runs.
We
are
also
including
in
the
final
rule
a
separate
batch
process
testing
provision
for
refractory
products
that
are
produced
infrequently.
In
such
cases,
we
are
allowing
owners
and
operators
of
affected
batch
process
sources
to
test
a
single
batch
process
cycle
using
two
separate
sampling
trains
simultaneously,
rather
than
requiring
them
to
conduct
test
runs
over
two
separate
batch
cycles.
Many
refractory
products
that
are
produced
in
batch
process
sources
are
specialty
items
that
may
only
be
manufactured
a
few
times
per
year.
When
such
products
represent
the
``
worst­
case''
in
terms
of
organic
HAP
emissions,
requiring
multiple
test
runs
over
separate
process
cycles
could
extend
the
test
period
over
several
weeks
or
months.
Production
of
other
refractory
products
could
inadvertently
be
disrupted
while
the
facility
attempts
to
complete
its
compliance
demonstration.
We
also
point
out
that
requiring
performance
tests
on
batch
process
sources
to
be
conducted
over
no
more
than
a
single
process
cycle
is
not
without
precedent;
at
least
four
other
NESHAP
(
subparts
U,
JJJ,
OOO,
and
UUUU
to
40
CFR
part
63)
require
batch
process
sources
to
be
tested
over
only
a
single
process
cycle.
To
satisfy
this
provision
of
today's
final
rule,
owners
or
operators
will
be
required
to
include
in
the
Notification
of
Performance
Test
an
explanation
for
why
testing
two
separate
batch
cycles
is
impractical.
Comment:
Two
commenters
expressed
concern
with
the
requirement
that
the
compliance
test
on
an
affected
source
would
have
to
be
repeated
before

Rules
and
Regulations
the
facility
began
manufacturing
a
new
product
that
represents
the
``
worst­
case''
in
terms
of
organic
HAP
emissions
(
i.
e.,
the
organic
HAP
processing
rate
for
the
new
product
would
exceed
the
maximum
organic
HAP
processing
rate
established
during
the
most
recent
performance
test).
One
commenter
stated
that
this
requirement
would
be
costly,
time­
consuming,
and
could
result
in
disruptions
in
production.
Another
commenter
further
elaborated
that
production
delays
could
result
while
the
facility
tries
to
schedule
a
performance
test.
Both
commenters
requested
that
we
specify
a
level
for
the
allowable
changes
in
the
HAP
content
of
raw
materials
and
not
require
a
new
compliance
test
when
the
changes
in
HAP
content
are
below
that
level.
One
of
the
commenters
stated
that
a
level
of
10
percent
would
be
appropriate.
Response:
We
agree
with
the
commenters
that
a
new
compliance
test
should
not
be
required
when
a
facility
begins
producing
a
new
product
that
constitutes
a
slight
increase
in
the
maximum
organic
HAP
processing
rate
established
during
the
most
recent
performance
test.
We
have
written
this
provision
in
the
final
rule
to
allow
increases
in
the
maximum
organic
HAP
processing
rate
up
to
10
percent
without
triggering
a
new
performance
test.
We
believe
this
is
appropriate
for
two
reasons.
The
HAP
content
of
some
raw
materials
(
e.
g.,
resins
or
binders)
used
in
refractory
products
manufacturing
can
vary
slightly
from
shipment
to
shipment,
and
those
variations
may
be
beyond
the
control
of
the
user.
Even
if
the
HAP
content
of
the
resin
or
binder
is
10
percent
more
than
the
HAP
content
of
the
same
material
that
was
processed
during
the
compliance
test,
the
net
increase
in
controlled
emissions
would
most
likely
be
within
the
measurement
error
of
the
test
method.
Therefore,
we
believe
it
is
reasonable
to
allow
increases
of
up
to
10
percent
in
the
organic
HAP
processing
rate
without
requiring
a
new
compliance
test.
Comment:
Two
commenters
questioned
the
requirement
for
monitoring
catalytic
oxidizer
temperatures
at
the
inlet
to
the
catalyst
bed.
Both
commenters
stated
that
monitoring
the
catalyst
bed
outlet
temperatures
would
be
a
much
better
indicator
of
performance.
Response:
We
disagree
with
the
commenters
that
monitoring
catalyst
bed
outlet
temperatures
would
provide
a
better
indication
of
catalyst
oxidizer
performance
than
monitoring
catalyst
bed
inlet
temperatures.
Monitoring
catalyst
bed
inlet
temperatures
ensures
that
the
inlet
gas
stream
is
heated
to
the
minimum
temperature
at
which
catalytic
oxidation
will
occur.
Above
this
minimum
temperature,
as
temperature
increases
through
catalytic
oxidization,
control
(
destruction)
efficiency
increases.
We
also
note
that
the
monitoring
of
inlet
temperature
must
be
performed
at
the
inlet
to
the
catalyst
bed
and
not
at
the
inlet
to
the
oxidizer
itself.
After
passing
through
the
inlet
to
the
oxidizer,
the
waste
gases
pass
through
a
preheat
zone,
which
raises
the
temperature
to
the
minimum
required
for
catalytic
oxidization.
Monitoring
must
take
place
between
this
preheat
zone
and
the
inlet
to
the
catalyst
bed.
We
do
not
believe
that
monitoring
catalyst
bed
outlet
temperatures
would
be
appropriate
for
two
reasons:
(
1)
Catalyst
bed
outlet
temperature
is
more
of
an
indicator
of
the
concentration
of
organics
in
the
inlet
gas
stream;
the
higher
the
organic
concentration
at
the
inlet,
the
higher
the
bed
outlet
temperature;
and
(
2)
some
catalytic
oxidizers
are
equipped
with
heat
recovery
units
that
are
located
at
the
outlet
of
the
catalyst
bed
and
can
interfere
with
bed
outlet
temperature
monitoring.
Consequently,
we
have
concluded
that
monitoring
the
bed
inlet
temperature
is
a
better
indicator
of
the
performance
of
catalytic
oxidizers
than
bed
outlet
temperature
monitoring.
We
continue
to
require
catalyst
bed
inlet
temperature
monitoring
in
the
final
rule.
In
addition,
we
are
requiring
owners
or
operators
of
affected
sources
that
are
controlled
with
catalytic
oxidizers
to
measure
the
activity
of
the
catalyst
bed
at
least
every
12
months
and
take
whatever
corrective
action
is
needed,
such
as
replacing
the
catalyst,
to
ensure
that
the
catalyst
is
performing
as
designed.

Economic
and
Environmental
Impacts
Comment:
Two
commenters
disagreed
with
our
estimates
of
the
annual
increase
in
energy
costs
that
would
be
associated
with
the
proposed
NESHAP.
One
of
the
commenters
stated
that,
based
on
our
estimated
annual
energy
costs
of
$
569,800
and
estimated
annual
natural
gas
consumption
of
644
million
cubic
feet
(
644
×
106
ft3),
the
unit
price
for
natural
gas
would
be
$
0.89
per
thousand
standard
cubic
feet
(
scf)
($/
1,000
scf)
without
accounting
for
electricity
costs.
If
the
cost
of
electricity
is
considered,
the
resulting
unit
price
for
natural
gas
would
be
even
lower.
He
pointed
out
that
current
unit
prices
for
natural
gas
are
considerably
higher.
The
average
natural
gas
unit
prices
in
four
States
(
Kentucky,
Missouri,
Indiana,
and
Pennsylvania)
for
the
years
2000
to
2002
ranged
from
$
6.34
to
$
6.97/
1,000
scf
and
averaged
$
6.37/
1,000
scf
for
the
four
States.
Based
on
data
from
the
Department
of
Energy's
Energy
Information
Administration
(
DOE­
EIA),
one
of
the
commenters
stated
that
the
average
unit
price
for
natural
gas
in
2001
was
$
4.56/
1,000
scf.
The
commenter
believes
that,
regardless
of
which
of
these
current
unit
prices
are
used,
the
estimated
annual
energy
costs
should
have
been
several
times
greater.
Response:
After
reviewing
our
estimated
annual
energy
costs,
we
discovered
an
error
in
our
estimate
that
an
additional
644
×
106
ft3
of
natural
gas
would
be
consumed
annually
under
the
proposed
NESHAP.
That
estimate
was
based
on
the
inclusion
of
several
sources
that
would
not
have
been
subject
to
the
final
rule.
However,
we
did
not
use
that
figure
(
644
×
106
ft3)
to
estimate
annual
energy
costs.
Our
estimated
annual
energy
costs
were
based
on
the
assumption
that
annual
natural
gas
consumption
would
increase
by
158
×
106
ft3.
That
figure
was
derived
from
the
models
used
to
estimate
annual
control
costs,
and
we
believe
that
figure
is
accurate.
Using
a
consumption
of
158
×
106
ft3
of
natural
gas
per
year
and
a
natural
gas
unit
price
of
$
3.30/
1,000
scf,
we
estimated
the
cost
of
natural
gas
to
be
$
520,200/
yr.
The
difference
between
this
cost
and
the
total
energy
costs
presented
in
the
preamble
to
the
proposed
rule
($
569,800)
is
the
cost
of
electricity,
which
we
estimated
to
be
approximately
$
49,600/
yr.
We
agree
with
the
commenters
that
current
natural
gas
unit
prices
are
considerably
higher
than
the
unit
price
($
3.30/
1,000
scf)
that
we
used
to
estimate
energy
costs
for
the
proposed
rule.
However,
according
to
DOE
 
EIA,
natural
gas
prices
are
projected
to
drop
back
to
their
pre­
1999
levels
within
a
year
and
remain
below
$
4.00/
1,000
scf
until
the
year
2020.
Natural
gas
unit
prices
are
projected
to
average
$
3.45/
1,000
scf
for
the
years
2006
to
2009,
which
represent
the
first
3
years
in
which
facilities
will
be
required
to
comply
with
the
Refractory
Products
Manufacturing
NESHAP.
This
average
unit
price
is
only
slightly
higher
than
the
unit
price
of
$
3.30/
1,000
scf
that
we
used
to
estimate
energy
costs
for
the
proposed
rule.
Furthermore,
electricity
prices
are
projected
by
DOE­
EIA
to
average
$
0.043
per
kilowatt­
hour
(
kwhr
for
the
same
3­
year
period,
whereas
our
estimated
energy
costs
were
based
on
electricity
unit
prices
of
$
0.059/
kwhr
Using
those
projected
unit
prices
for
natural
gas
and
electricity,
our
energy
costs
for
the
proposed
rule
would
have
been
$
580,000,
as
compared
to
the
figure
of
$
569,800
reported
in
the
preamble
to
the
proposed
rule.

Comment:
Two
commenters
stated
that
the
proposed
Refractory
Products
Manufacturing
NESHAP
does
not
account
for
the
current
economic
status
of
the
refractory
products
manufacturing
industry.
One
of
the
commenters
noted
that
approximately
40
percent
of
the
domestic
steel
industry
is
in
bankruptcy,
and
the
steel
industry
accounts
for
about
60
percent
of
the
domestic
refractory
products
market.
He
also
pointed
out
that
three
major
refractory
products
manufacturing
companies
are
in
bankruptcy,
more
than
30
plants
have
permanently
closed
in
recent
years,
and
pressure
from
foreign
competition
in
the
refractory
products
market
is
increasing.
The
other
commenter
reiterated
the
statements
of
the
first
commenter
regarding
bankruptcies
among
major
domestic
refractory
producers
and
the
increase
in
foreign
competition.
Response:
During
the
early
stages
of
regulatory
development,
we
issued
an
information
collection
request
(
ICR)
to
the
refractory
products
manufacturing
industry.
Our
economic
impact
analysis
(
EIA)
makes
use
of
detailed
facility­
level
data
on
production
for
the
year
1997
obtained
from
the
industry's
responses
to
the
ICR.
This
information,
along
with
publically
available
data
(
i.
e.,
U.
S.
Census
Bureau),
was
used
at
proposal
to
construct
a
model
of
the
markets
for
refractory
products
that
is
consistent
with
market,
facility,
and
company
conditions
in
1997.
Because
the
ICR
provided
data
only
for
1997,
we
are
limited
in
our
ability
to
update
the
model
completely
to
reflect
conditions
in
later
years.
However,
for
the
final
rule
we
have,
to
the
extent
practicable,
updated
the
economic
model
to
reflect
current
market
conditions,
including:
(
1)
The
exclusion
of
refractory
manufacturing
facilities
known
to
have
closed
since
the
base
year
of
1997;
(
2)
the
assumption
that
producers
will
absorb
the
full
cost
of
the
rule;
with
only
six
out
of
147
producers
affected
by
the
rule
and
the
financial
stress
on
the
industry,
we
assume
producers
will
be
unable
to
increase
market
prices
to
recover
some
of
their
increase
in
production
costs;
and
(
3)
the
incorporation
of
parameters
from
a
recent
update
of
an
iron
and
steel
model
to
inform
the
estimated
demand
for
refractories
(
i.
e.,
the
demand
elasticity,
or
the
sensitivity
of
demand
from
the
steel
market
based
on
market
conditions
in
the
iron
and
steel
industry).
The
iron
and
steel
model
was
specifically
revised
to
address
current
conditions
in
the
steel
industry.
We
also
acknowledged
in
the
EIA
at
proposal
that
both
steel
and
refractory
manufacturing
companies
are
currently
under
financial
stress.
In
the
EIA,
we
discussed
several
trends
that
have
placed
considerable
pressure
on
refractory
manufacturers,
including
reduced
production
by
integrated
domestic
steelmakers,
improved
quality
of
refractories
(
thus
requiring
less
frequent
replacement),
and
increased
imports
of
refractory
products.
We
note
that
the
vast
majority
of
facilities
in
the
industry
(
both
foreign
and
domestic
producers)
are
unaffected
by
the
rule.
The
regulatory
costs
of
the
rule
are
approximately
$
2
million
per
year,
which
represents
a
small
share
of
total
industry
production
costs
of
approximately
$
2,300
million
per
year.
In
the
model
for
the
final
rule,
prices
are
not
predicted
to
change,
and
the
quantities
of
refractories
produced
are
projected
to
decrease
by
3,792
tons.
It
is
assumed
that
the
loss
in
domestic
production
will
be
absorbed
by
foreign
imports.
Our
analysis
concludes
these
six
facilities
incurring
regulatory
costs
will
absorb
the
majority
of
the
costs
and
burden
of
the
rule,
with
one
facility
projected
to
close
as
a
result
of
the
rule.
At
the
parent
company
level,
the
costs
uniformly
are
less
than
1
percent
of
baseline
corporate
sales.
Overall,
we
have
adjusted
the
economic
model
to
address
the
issues
raised
by
the
commenters,
and
we
believe
that
the
final
rule
will
have
a
limited
impact
on
the
refractory
products
manufacturing
industry.

E.
Definitions
Comment:
Two
commenters
commented
on
how
the
term
refractory
product
is
defined
in
the
proposed
rule.
Both
commenters
stated
that,
based
on
this
definition,
some
graphite
manufacturing
sources
could
be
confused
with
certain
refractory
products
manufacturing
sources
that
would
be
affected
by
the
final
rule.
It
is
their
understanding
that
we
intend
to
develop
a
separate
NESHAP
for
the
graphite
manufacturing
industry,
and
graphite
manufacturing
sources,
although
similar
to
some
refractory
products
manufacturing
sources,
would
not
be
subject
to
the
Refractory
Products
Manufacturing
NESHAP.
The
commenters
suggested
adding
the
phrase,
``.
.
.
containing
less
than
50
percent
carbon''
to
the
definition
of
refractory
product.
Response:
We
agree
with
the
commenters
that
the
definition
of
refractory
product
in
the
proposed
rule
could
inadvertently
affect
certain
graphite
manufacturing
sources.
Consequently,
we
have
written
the
definition
as
requested
by
the
commenters.
In
addition,
we
are
including
a
definition
for
pitch­
bonded
refractory
products
in
the
final
rule.
We
believe
that
definition
will
help
to
preclude
graphite
baking
ovens,
which
are
not
subject
to
today's
final
rule,
from
being
classified
as
pitch­
bonded
curing
ovens,
which
are
regulated
under
today's
final
rule.
Comment:
One
commenter
commented
on
how
the
term
research
and
development
process
unit
is
defined
in
the
proposed
rule.
The
commenter
stated
that
the
proposed
definition
is
inconsistent
with
the
definition
of
research
and
development
facilities
specified
in
section
112(
c)(
7)
of
the
CAA,
40
CFR
63.41,
and
several
other
NESHAP
published
in
40
CFR
part
63.
The
difference
between
those
definitions
and
the
proposed
definition
specified
in
the
Refractory
Products
Manufacturing
NESHAP
is
the
exclusion
of
the
phrase
``
in
a
de
minimis
manner''
from
the
proposed
rule.
Response:
We
agree
with
the
commenter
that
the
definition
of
research
and
development
process
unit
in
the
Refractory
Products
Manufacturing
NESHAP
should
be
consistent
with
the
definition
of
research
facilities
in
the
CAA
and
in
other
rules.
We
have
written
the
definition
of
research
and
development
process
unit
as
suggested
by
the
commenter.

V.
Summary
of
Impacts
A.
What
Are
the
Health
Impacts?

The
HAP
that
will
be
controlled
by
today's
final
rule
are
associated
with
a
variety
of
adverse
health
effects.
These
adverse
health
effects
include
chronic
health
disorders
(
e.
g.,
irritation
of
the
lung,
skin,
and
mucous
membranes,
gastrointestinal
effects,
and
damage
to
the
kidneys
and
liver)
and
acute
health
disorders
(
e.
g.,
respiratory
irritation
and
central
nervous
system
effects
such
as
drowsiness,
headache,
and
nausea).
The
EPA
has
classified
two
of
the
HAP
(
formaldehyde
and
POM)
as
probable
human
carcinogens.
The
EPA
does
not
have
the
type
of
current
detailed
data
on
each
of
the
facilities
and
the
people
living
around
the
facilities
covered
by
today's
final
rule
for
this
source
category
that
would
be
necessary
to
conduct
an
analysis
to
determine
the
actual
population
exposures
to
the
HAP
emitted
from
these
facilities
and
the
potential
for
resultant
health
effects.
Therefore,
EPA
does
not
know
the
extent
to
which
the
adverse
health
effects
described
above
occur
in
the
populations
surrounding

Rules
and
Regulations
these
facilities.
However,
to
the
extent
the
adverse
effects
do
occur,
and
today's
final
rule
reduces
emissions,
subsequent
exposures
will
be
reduced.
Following
is
a
discussion
of
the
health
effects
of
seven
HAP:
ethylene
glycol,
formaldehyde,
HF,
HCl,
methanol,
phenol,
and
POM.
Although
today's
rule
will
reduce
emissions
of
HF
and
HCl
from
any
new
clay
refractory
product
kilns
that
emit
these
HAP,
it
will
not
reduce
emissions
of
these
HAP
from
existing
kilns.
We
estimate
that
emissions
of
methanol
from
affected
existing
thermal
process
sources
of
organic
HAP
(
i.
e.,
shape
dryers,
curing
ovens,
and
kilns)
also
will
not
be
reduced
by
today's
final
rule.
However,
methanol
is
a
constituent
of
some
resins
used
in
resin­
bonded
refractory
production,
and
today's
final
rule
will
regulate
methanol
emissions
from
any
affected
source
that
produces
refractory
products
made
with
resins
that
contain
methanol.

Ethylene
Glycol
Acute
(
short­
term)
exposure
of
humans
to
ethylene
glycol
by
ingesting
large
quantities
causes
central
nervous
system
depression
(
including
drowsiness
and
respiratory
failure),
gastrointestinal
upset,
cardiopulmonary
effects,
and
renal
damage.
The
only
effects
noted
in
the
one
available
study
of
humans
acutely
exposed
to
low
levels
of
ethylene
glycol
by
inhalation
were
throat
and
upper
respiratory
tract
irritation.
Rats
and
mice
exposed
chronically
(
long­
term)
to
ethylene
glycol
in
their
diet
exhibited
signs
of
kidney
toxicity
and
liver
effects.
No
information
is
available
on
the
reproductive
or
developmental
effects
of
ethylene
glycol
in
humans,
but
several
studies
of
rodents
have
shown
ethylene
glycol
to
be
fetotoxic.
The
EPA
has
not
classified
ethylene
glycol
for
carcinogenicity.

Formaldehyde
Both
acute
and
chronic
exposure
to
formaldehyde
irritates
the
eyes,
nose,
and
throat,
and
may
cause
coughing,
chest
pains,
and
bronchitis.
Reproductive
effects,
such
as
menstrual
disorders
and
pregnancy
problems,
have
been
reported
in
female
workers
exposed
to
formaldehyde.
Limited
human
studies
have
reported
an
association
between
formaldehyde
exposure
and
lung
and
nasopharyngeal
cancer.
Animal
inhalation
studies
have
reported
an
increased
incidence
of
nasal
squamous
cell
cancer.
The
EPA
considers
formaldehyde
a
probable
human
carcinogen
(
Group
B2).
Hydrogen
Fluoride
Acute
inhalation
exposure
to
gaseous
HF
can
cause
severe
respiratory
damage
in
humans,
including
severe
irritation
and
pulmonary
edema.
Chronic
exposure
to
fluoride
at
low
levels
has
a
beneficial
effect
of
dental
cavity
prevention
and
may
also
be
useful
for
the
treatment
of
osteoporosis.
Exposure
to
higher
levels
of
fluoride
may
cause
dental
fluorosis
or
mottling,
while
very
high
exposures
through
drinking
water
or
air
can
result
in
crippling
skeletal
fluorosis.
One
study
reported
menstrual
irregularities
in
women
occupationally
exposed
to
fluoride.
The
EPA
has
not
classified
HF
for
carcinogenicity.

Hydrogen
Chloride
Hydrogen
chloride,
also
called
hydrochloric
acid,
is
corrosive
to
the
eyes,
skin,
and
mucous
membranes.
Acute
inhalation
exposure
may
cause
eye,
nose,
and
respiratory
tract
irritation
and
inflammation
and
pulmonary
edema
in
humans.
Chronic
occupational
exposure
to
HCl
has
been
reported
to
cause
gastritis,
bronchitis,
and
dermatitis
in
workers.
Prolonged
exposure
to
low
concentrations
may
also
cause
dental
discoloration
and
erosion.
No
information
is
available
on
the
reproductive
or
developmental
effects
of
HCl
in
humans.
In
rats
exposed
to
HCl
by
inhalation,
altered
estrus
cycles
have
been
reported
in
females,
and
increased
fetal
mortality
and
decreased
fetal
weight
have
been
reported
in
offspring.
The
EPA
has
not
classified
HCl
for
carcinogenicity.

Methanol
Acute
or
chronic
exposure
of
humans
to
methanol
by
inhalation
or
ingestion
may
result
in
blurred
vision,
headache,
dizziness,
and
nausea.
No
information
is
available
on
the
reproductive,
developmental,
or
carcinogenic
effects
of
methanol
in
humans.
Birth
defects
have
been
observed
in
the
offspring
of
rats
and
mice
exposed
to
methanol
by
inhalation.
A
methanol
inhalation
study
using
rhesus
monkeys
reported
a
decrease
in
the
length
of
pregnancy
and
limited
evidence
of
impaired
learning
ability
in
offspring.
The
EPA
has
not
classified
methanol
with
respect
to
carcinogenicity.

Phenol
Acute
inhalation
and
dermal
exposure
to
phenol
is
highly
irritating
to
the
skin,
eyes,
and
mucous
membranes
in
humans.
Oral
exposure
to
small
amounts
of
phenol
may
cause
irregular
breathing,
muscular
weakness
and
tremors,
coma,
and
respiratory
arrest
at
lethal
concentrations.
Anorexia,
progressive
weight
loss,
diarrhea,
vertigo,
salivation,
and
a
dark
coloration
of
the
urine
have
been
reported
in
chronically
exposed
humans.
Gastrointestinal
irritation
and
blood
and
liver
effects
have
also
been
reported.
No
studies
of
developmental
or
reproductive
effects
of
phenol
in
humans
are
available,
but
animal
studies
have
reported
reduced
fetal
body
weights,
growth
retardation,
and
abnormal
development
in
the
offspring
of
animals
exposed
to
phenol
by
the
oral
route.
The
EPA
has
classified
phenol
in
Group
D,
not
classifiable
as
to
human
carcinogenicity.

Polycyclic
Organic
Matter
The
term
polycyclic
organic
matter
defines
a
broad
class
of
compounds
that
includes
the
polycyclic
aromatic
hydrocarbon
(
PAH)
compounds,
of
which
benzo[
a]
pyrene
is
a
member.
Dermal
exposures
to
mixtures
of
PAH
cause
skin
disorders
in
humans
and
animals.
No
information
is
available
on
the
reproductive
or
developmental
effects
of
POM
in
humans,
but
animal
studies
have
reported
that
oral
exposure
to
benzo[
a]
pyrene
causes
reproductive
and
developmental
effects.
Human
studies
have
reported
an
increase
in
lung
cancer
in
humans
exposed
to
POMbearing
mixtures
including
coke
oven
emissions,
roofing
tar
emissions,
and
cigarette
smoke.
Animal
studies
have
reported
respiratory
tract
tumors
from
inhalation
exposure
to
benzo[
a]
pyrene
and
forestomach
tumors,
leukemia,
and
lung
tumors
from
oral
exposure
to
benzo[
a]
pyrene.
The
EPA
has
classified
seven
PAH
compounds
(
benzo[
a]
pyrene,
benz[
a]
anthracene,
chrysene,
benzo[
b]
fluoranthene,
benzo[
k]
fluoranthene,
dibenz[
a,
h]
anthracene,
and
indeno[
1,2,3­
cd]
pyrene)
as
Group
B2,
probable
human
carcinogens.

B.
What
Are
the
Air
Emission
Reduction
Impacts?
At
the
current
level
of
control
and
1996
production
levels,
we
estimate
nationwide
emissions
of
HAP
from
the
refractory
products
manufacturing
industry
to
be
about
246
Mg/
yr
(
271
tpy).
For
the
eight
refractory
products
facilities
that
we
estimate
to
be
major
sources,
baseline
annual
HAP
emissions
are
about
153
Mg/
yr
(
169
tpy).
We
estimate
that
today's
final
rule
will
reduce
nationwide
HAP
emissions
by
about
124
Mg/
yr
(
137
tpy).
Among
the
major
sources,
POM
emissions
account
for
approximately
60
percent
of
the
total
annual
HAP
emissions.
Phenol,
HF,
HCl,
and
ethylene
glycol
account
for
13
percent,
10
percent,
7
percent,
and
7
percent
of
total
annual
HAP
emissions,

respectively.
Formaldehyde
and
chromium
compounds
each
account
for
less
than
1
percent
of
total
baseline
annual
HAP
emissions.
Today's
final
rule
will
reduce
annual
POM
emissions
by
as
much
as
90
Mg/
yr
(
99
tpy).
Emissions
of
phenol
and
ethylene
glycol
will
be
reduced
by
approximately
19
Mg/
yr
(
21
tons/
year)
and
11
Mg/
yr
(
12
tpy),
respectively.
Implementing
today's
rule
will
also
reduce
volatile
organic
compound
(
VOC)
and
carbon
monoxide
(
CO)
emissions
by
166
Mg/
yr
(
182
tpy)
and
71
Mg/
yr
(
78
tpy),
respectively.
The
final
rule
will
result
in
an
increase
in
annual
nitrogen
oxides
(
NOX)
emissions
of
about
79
Mg/
yr
(
87
tpy)
due
to
the
operation
of
additional
thermal
oxidizers
to
control
organic
HAP
emissions.
Indirect
or
secondary
air
impacts
of
today's
final
rule
result
from
increased
electricity
usage
associated
with
operation
of
control
devices
required
by
the
rule.
Assuming
that
affected
plants
will
purchase
electricity
from
a
power
plant,
we
estimate
that
the
final
rule
will
result
in
increases
of
secondary
emissions
of
criteria
pollutants,
including
particulate
matter
less
than
10
micrometers
in
aerodynamic
diameter
(
PM
 
10),
sulfur
dioxide
(
SO2),
NOX,
and
CO
from
power
plants.
Under
today's
final
rule,
secondary
PM
 
10
emissions
will
increase
by
0.22
Mg/
yr
(
0.24
tpy);
secondary
SO2
emissions
will
increase
by
about
8.9
Mg/
yr
(
9.8
tpy);
secondary
NOX
emissions
will
increase
about
4.5
Mg/
yr
(
4.9
tpy);
and
secondary
CO
emissions
will
increase
by
about
0.15
Mg/
yr
(
0.16
tpy).
We
estimate
that
there
will
be
no
new
sources
within
the
refractory
products
manufacturing
industry
within
the
next
3
years.
Therefore,
we
are
not
projecting
air
impacts
for
new
sources
under
today's
final
rule.

C.
What
Are
the
Cost
Impacts?
The
estimated
total
capital
costs
of
today's
final
rule
are
$
4.6
million.
These
capital
costs
apply
to
existing
sources
and
include
the
costs
to
purchase
and
install
thermal
oxidizers
on
affected
sources
that
are
not
currently
controlled.
The
estimated
annualized
cost
of
today's
final
rule
is
$
2.3
million.
The
annualized
costs
account
for
the
annualized
capital
costs
of
the
control
and
monitoring
equipment,
operation
and
maintenance
expenses,
performance
testing,
and
recordkeeping
and
reporting
costs.

D.
What
Are
the
Economic
Impacts?
Given
the
estimated
costs
to
comply
with
the
regulation,
we
prepared
an
economic
analysis
to
evaluate
how
these
costs
would
impact
producers
and
consumers
of
refractories,
and
society
as
a
whole.
The
refractory
products
manufacturing
industry
currently
consists
of
147
establishments.
There
are
eight
major
sources
in
the
industry
affected
by
the
rule,
six
of
which
will
incur
costs
to
reduce
emissions
and
report
compliance,
and
two
of
which
only
incur
minor
recordkeeping
and
reporting
costs.
In
recent
years,
the
industry
has
experienced
substantial
financial
stress
that
coincides
with
the
decline
in
the
steel
industry,
which
is
a
major
consumer
of
refractory
products.
Since
our
analysis
at
proposal,
the
number
of
facilities
in
operation
has
decreased
by
14
due
to
bankruptcies
or
closures.
The
industry
consists
of
three
market
sectors,
including:
bricks
and
shapes,
monolithics,
and
RCF.
In
1997,
the
industry
produced
about
two
million
tons
of
bricks
and
shapes,
870,000
tons
of
monolithics,
and
about
34,000
tons
of
RCF
for
a
total
market
value
of
approximately
two
billion
dollars.
The
total
annualized
regulatory
compliance
cost
of
the
rule
is
$
2.3
million
(
in
1998
dollars),
which
represents
0.001
percent
of
total
market
value.
Because
foreign
competition
currently
has
a
strong
influence
on
this
industry,
and
only
six
out
of
147
producers
are
affected
by
the
rule,
our
analysis
of
the
final
rule
assumes
that
producers
of
bricks
and
shapes
will
not
be
able
to
increase
prices
to
recover
a
portion
of
the
compliance
costs.
Thus,
these
producers
are
assumed
to
absorb
the
full
cost
of
the
regulation,
which
represents
the
maximum
potential
impact
on
producers.
If
prices
happen
to
rise
as
a
result
of
the
regulation,
impacts
on
producers
will
be
lower
than
reported
here.
Our
analysis
predicts
that
domestic
production
of
bricks
and
shapes
will
decrease
by
approximately
4,000
tons
(
or
2/
10ths
of
one
percent).
Foreign
imports
are
assumed
to
absorb
this
loss
in
domestic
production,
which
represents
approximately
two
percent
of
total
foreign
imports.
The
monolithics
and
RCF
sectors
of
the
market
are
not
subject
to
the
rule
and
thus
no
price
or
production
level
changes
are
predicted.
After
accounting
for
the
changes
in
the
market
for
refractories
and
the
increase
in
foreign
imports,
the
total
cost
of
the
regulation
on
society
as
a
whole
is
approximately
$
2
million.
Of
the
eight
plants
affected
by
the
rule,
one
facility
may
close
due
to
regulatory
costs.
The
estimated
regulatory
cost
to
this
facility
assumes
the
use
of
add­
on
controls,
which
would
exceed
the
total
revenues
of
this
facility,
hence
our
model
estimates
that
it
would
close.
However,
we
recognize
that
this
facility,
as
well
as
the
other
affected
facilities,
have
several
options
to
change
input
materials,
or
attributes
of
their
production
process
such
that
they
could
substantially
reduce
the
cost
associated
with
add­
on
control
technology.
Without
explicit
knowledge
of
decisions
to
be
made
by
this
and
other
facilities
in
response
to
the
regulation,
our
analysis
assumes
that
only
add­
on
control
technology
will
be
installed.

E.
What
Are
the
Non­
Air
Quality
Environmental
and
Energy
Impacts?

To
comply
with
today's
final
rule,
we
expect
that
affected
facilities
will
control
organic
HAP
emissions
by
installing
and
operating
thermal
oxidizers.
Therefore,
we
project
that
today's
rule
will
have
no
water
or
solid
waste
impacts.
Energy
impacts
consist
of
the
electricity
and
fuel
needed
to
operate
control
devices
and
other
equipment
that
are
required
under
the
final
rule.
Assuming
that
affected
facilities
comply
with
the
final
rule
by
installing
and
operating
thermal
oxidizers,
we
project
that
today's
final
rule
will
increase
overall
energy
demand
(
i.
e.,
electricity
and
natural
gas)
by
about
280
thousand
gigajoules
per
year
(
265
billion
British
thermal
units
per
year).
Electricity
requirements
are
expected
to
increase
by
about
1,570
megawatt­
hours
per
year
under
today's
rule.
Natural
gas
requirements
are
expected
to
increase
by
about
7
million
cubic
meters
per
year
(
250
million
cubic
feet
per
year)
under
today's
final
rule.

VI.
Statutory
and
Executive
Order
Reviews
A.
Executive
Order
12866:
Regulatory
Planning
and
Review
Under
Executive
Order
12866
(
58
FR
51735,
October
4,
1993),
EPA
must
determine
whether
the
regulatory
action
is
``
significant''
and,
therefore,
subject
to
review
by
the
Office
of
Management
and
Budget
(
OMB)
and
the
requirements
of
the
Executive
Order.
The
Executive
Order
defines
``
significant
regulatory
action''
as
one
that
is
likely
to
result
in
a
rule
that
may:
(
1)
Have
an
annual
effect
on
the
economy
of
$
100
million
or
more
or
adversely
affect
in
a
material
way
the
economy,
a
sector
of
the
economy,
productivity,
competition,
jobs,
the
environment,
public
health
or
safety,
or
State,
local,
or
tribal
governments
or
communities;
(
2)
Create
a
serious
inconsistency
or
otherwise
interfere
with
an
action
taken
or
planned
by
another
agency;
(
3)
Materially
alter
the
budgetary
impact
of

it
has
been
determined
that
this

The
information
requirements
are
not
enforceable
until
OMB
approves
them.
The
information
requirements
are
based
on
notification,
recordkeeping,
and
reporting
requirements
in
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
which
are
mandatory
for
all
operators
subject
to
national
emission
standards.
These
recordkeeping
and
reporting
requirements
are
specifically
authorized
by
section
114
of
the
CAA
(
42
U.
S.
C.
7414).
All
information
submitted
to
EPA
pursuant
to
the
recordkeeping
and
reporting
requirements
for
which
a
claim
of
confidentiality
is
made
is
safeguarded
according
to
EPA's
policies
set
forth
in
40
CFR
part
2,
subpart
B.
With
two
exceptions,
the
final
rule
will
not
require
any
notifications,
reports,
or
recordkeeping
beyond
those
required
by
the
NESHAP
General
Provisions.
The
first
exception
applies
to
facilities
that
operate
sources
that
are
subject
to
limits
on
the
type
of
fuel
used.
In
such
cases,
the
owner
or
operator
may
use
an
alternative
fuel
under
certain
conditions
but
must
submit
a
notification
before
using
the
alternative
fuel,
must
report
on
alternative
fuel
use
after
terminating
use
of
the
alternative
fuel,
and
must
maintain
records
of
alternative
fuel
use.
The
second
exception
pertains
to
continuous
kilns;
the
final
rule
requires
reporting
and
recordkeeping
whenever
the
control
device
used
on
a
continuous
kiln
is
taken
offline
for
scheduled
maintenance.
The
annual
monitoring,
reporting,
and
recordkeeping
burden
for
this
collection
of
information
(
averaged
over
the
first
3
years
after
the
effective
date
of
the
rule)
is
estimated
to
be
726
labor
hours
per
year
at
a
total
annual
cost
of
$
31,460.
This
burden
estimate
includes
time
for
acquisition,
installation,
and
use
of
monitoring
technology
and
systems;
preparation
and
a
one­
time
submission
of
an
SSMP,
with
immediate
reports
for
any
event
when
the
procedures
in
the
plan
were
not
followed;
preparation
of
an
OM&
M
plan;
one­
time
notifications;
semiannual
compliance
reports;
and
recordkeeping.
Total
annualized
capital/
startup
costs
associated
with
the
monitoring
requirements
(
e.
g.,
costs
for
hiring
performance
test
contractors
and
purchase
of
monitoring
and
file
storage
equipment)
over
the
3­
year
period
of
the
ICR
are
estimated
at
$
45,390,
with
operation
and
maintenance
costs
of
$
910/
yr.
Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
persons
to
generate,
maintain,
retain,
or
disclose
or
provide
information
to
or
for
a
Federal
agency.
This
includes
the
time
needed
to
review
instructions;
develop,
acquire,
install,
and
utilize
technology
and
systems
for
the
purposes
of
collecting,
validating,
and
verifying
information,
processing
and
maintaining
information,
and
disclosing
and
providing
information;
adjust
the
existing
ways
to
comply
with
any
previously
applicable
instructions
and
requirements;
train
personnel
to
be
able
to
respond
to
a
collection
of
information;
search
data
sources;
complete
and
review
the
collection
of
information;
and
transmit
or
otherwise
disclose
the
information.
An
Agency
may
not
conduct
or
sponsor,
and
a
person
is
not
required
to
respond
to,
a
collection
of
information
unless
it
displays
a
current
valid
OMB
control
number.
The
OMB
control
numbers
for
EPA's

in
40
CFR
part
9
and
48
CFR
chapter
15.

C.
Regulatory
Flexibility
Act
(
RFA)
The
EPA
has
determined
that
it
is
not
necessary
to
prepare
a
regulatory
flexibility
analysis
in
connection
with
the
final
rule.
The
EPA
has
also
determined
that
the
rule
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
For
purposes
of
assessing
the
impact
of
today's
rule
on
small
entities,
small
entities
are
defined
as:
(
1)
A
small
business
whose
parent
company
has
fewer
than
500
employees,
according
to
Small
Business
Administration
size
standards
established
under
the
NAICS
for
the
industries
affected
by
today's
rule;
(
2)
a
small
governmental
jurisdiction
that
is
a
government
or
a
city,
county,
town,
school
district
or
special
district
with
a
population
of
less
than
50,000;
or
(
3)
a
small
organization
that
is
any
not­
for­
profit
enterprise
that
is
independently
owned
and
operated
and
is
not
dominant
in
its
field.
After
considering
the
economic
impacts
of
today's
final
rule
on
small
entities,
EPA
has
concluded
that
this
action
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
We
have
determined
that
of
the
six
facilities
affected
by
the
rule,
there
is
one
facility
owned
by
a
small
company
that
will
experience
an
impact
of
less
than
onehalf
of
one
percent
(<
0.50
percent)
of
company
sales.
Although
the
final
rule
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities,
EPA
nonetheless
has
tried
to
reduce
the
impact
of
the
rule
on
small
entities.
However,
we
were
unable
to
identify
any
specific
requirements
of
the
final
rule
that
we
could
relax
to
reduce
the
burden
of
today's
rule
on
small
entities.
If
the
final
rule
had
established
emission
limits
more
stringent
than
the
MACT
floor,
we
could
have
reduced
the
stringency
of
the
emission
limits
for
small
entities.
However,
the
emission
limits
established
by
today's
rule
are
based
on
the
MACT
floor,
which
is
the
minimum
level
of
stringency
allowed
under
section
112
of
the
CAA.
Today's
rule
does
provide
two
options
for
owners
and
operators
of
affected
thermal
process
sources
of
organic
HAP.
Thus,
the
one
small
entity
that
is
affected
by
today's
rule
can
choose
to
comply
with
either
of
two
organic
HAP
emission
limits.
Having
the
choice
between
compliance
options
will
provide
small
business
with
some
measure
of
flexibility
in
how
it
chooses
to
comply
with
the
final
rule.
Today's
rule
requires
continuous
parameter
monitoring
rather
than
continuous
emission
monitoring.
We
believe
that
the
parameter
monitoring
requirements
we
have
incorporated
in
the
final
rule
satisfy
the
requirements
of
section
114(
a)(
3)
of
the
CAA
for
enhanced
monitoring
without
the
additional
expense
that
would
have
been
associated
with
continuous
emission
monitoring.
Finally,
the
reporting
and
recordkeeping
requirements
of
today's
rule
are
consistent
with
the
requirements
of
the
General
Provisions
to
40
CFR
part
63.
For
these
reasons,
we
believe
that
today's
rule
satisfies
the
requirements

D.
Unfunded
Mandates
Reform
Act
Title
II
of
the
Unfunded
Mandates
Reform
Act
of
1995
(
UMRA),
Public
Law
No.
104
 
4,
establishes
requirements
for
Federal
agencies
to
assess
the
effects
of
their
regulatory
actions
on
State,
local,
and
tribal
governments
and
the
private
sector.
Under
section
202
of
the
UMRA,
EPA
generally
must
prepare
a
written
statement,
including
a
cost­
benefit
analysis,
for
proposed
and
final
rules
with
``
Federal
mandates''
that
may
result
in
expenditures
by
State,
local,
and
tribal
governments,
in
the
aggregate,
or
by
the
private
sector,
of
$
100
million
or
more
in
any
1
year.
Before
promulgating
an
EPA
rule
for
which
a
written
statement
is
needed,
section
205
of
the
UMRA
generally
requires
EPA
to
identify
and
consider
a
reasonable
number
of
regulatory
alternatives
and
adopt
the
least
costly,
most
costeffective
or
least
burdensome
alternative
that
achieves
the
objectives
of
the
rule.
The
provisions
of
section
205
do
not
apply
when
they
are
inconsistent
with
applicable
law.
Moreover,
section
205
allows
EPA
to
adopt
an
alternative
other
than
the
least
costly,
most
cost­
effective,
or
least
burdensome
alternative
if
the
Administrator
publishes
with
the
final
rule
an
explanation
why
that
alternative
was
not
adopted.
Before
EPA
establishes
any
regulatory
requirements
that
may
significantly
or
uniquely
affect
small
governments,
including
tribal
governments,
it
must
have
developed
under
section
203
of
the
UMRA
a
small
government
agency
plan.
The
plan
must
provide
for
notifying
potentially
affected
small
governments,
enabling
officials
of
affected
small
governments
to
have
meaningful
and
timely
input
in
the
development
of
EPA's
regulatory
proposals
with
significant
Federal
intergovernmental
mandates,
and
informing,
educating,
and
advising
small
governments
on
compliance
with
the
regulatory
requirements.
The
EPA
has
determined
that
today's
final
rule
does
not
contain
a
Federal
mandate
that
may
result
in
expenditures
of
$
100
million
or
more
for
State,
local,
and
tribal
governments,
in
the
aggregate,
or
the
private
sector
in
any
1
year.
The
maximum
total
annual
cost
of
today's
final
rule
for
any
year
has
been
estimated
to
be
approximately
$
2.3
million.
Thus,
this
final
rule
is
not
subject
to
the
requirements
of
sections
202
and
205
of
the
UMRA.
In
addition,
EPA
has
determined
that
this
final
rule
contains
no
regulatory
requirements
that
might
significantly
or
uniquely
affect
small
governments
because
it
contains
no
requirements
that
apply
to
such
governments
or
impose
obligations
upon
them.
Therefore,
today's
final
rule
is
not
subject
to
the
requirements
of
section
203
of
the
UMRA.

E.
Executive
Order
13132:
Federalism
Executive
Order
13132,
entitled
``
Federalism''
(
64
FR
43255,
August
10,
1999),
requires
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
State
and
local
officials
in
the
development
of
regulatory
policies
that
have
federalism
implications.''
``
Policies
that
have
federalism
implications''
is
defined
in
the
Executive
Order
to
include
regulations
that
have
``
substantial
direct
effects
on
the
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government.''
The
final
rule
does
not
have
federalism
implications.
It
will
not
have
substantial
direct
effects
on
the
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government,
as
specified
in
Executive
Order
13132.
None
of
the
affected
facilities
is
owned
or
operated
by
State
governments,
and
the
rule
requirements
will
not
supercede
State
regulations
that
are
more
stringent.
Thus,
Executive
Order
13132
does
not
apply
to
the
rule.

F.
Executive
Order
13175:
Consultation
and
Coordination
With
Indian
Tribal
Governments
Executive
Order
13175,
entitled
``
Consultation
and
Coordination
with
Indian
Tribal
Governments''
(
65
FR
67249,
November
9,
2000),
requires
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
tribal
officials
in
the
development
of
regulatory
policies
that
have
tribal
implications.''
The
final
rule
does
not
have
tribal
implications,
as
specified
in
Executive
Order
13175.
It
will
not
have
substantial
direct
effects
on
tribal
governments,
on
the
relationship
between
the
Federal
government
and
Indian
tribes,
or
on
the
distribution
of
power
and
responsibilities
between
the
Federal
government
and
Indian
tribes,
as
specified
in
Executive
Order
13175.
No
tribal
governments
own
or
operate
refractory
products
manufacturing
facilities.
Thus,
Executive
Order
13175
does
not
apply
to
the
final
rule.
G.
Executive
Order
13045:
Protection
of
Children
From
Environmental
Health
Risks
and
Safety
Risks
Executive
Order
13045
(
62
FR
19885,
April
23,
1997)
applies
to
any
rule
that:
(
1)
Is
determined
to
be
``
economically
significant''
as
defined
under
Executive
Order
12866,
and
(
2)
concerns
an
environmental
health
or
safety
risk
that
EPA
has
reason
to
believe
may
have
a
disproportionate
effect
on
children.
If
the
regulatory
action
meets
both
criteria,
EPA
must
evaluate
the
environmental
health
or
safety
effects
of
the
planned
rule
on
children,
and
explain
why
the
planned
rule
is
preferable
to
other
potentially
effective
and
reasonably
feasible
alternatives
that
EPA
considered.
The
EPA
interprets
Executive
Order
13045
as
applying
only
to
those
regulatory
actions
that
are
based
on
health
or
safety
risks,
such
that
the
analysis
required
under
section
5
 
501
of
the
Executive
Order
has
the
potential
to
influence
the
regulation.
Today's
final
rule
is
not
subject
to
Executive
Order
13045
because
it
is
based
on
technology
performance
and
not
on
health
or
safety
risks.
No
children's
risk
analysis
was
performed
because
no
alternative
technologies
exist
that
would
provide
greater
stringency
at
a
reasonable
cost.
Furthermore,
the
final
rule
has
been
determined
not
to
be
``
economically
significant''
as
defined
under
Executive
Order
12866.

H.
Executive
Order
13211:
Actions
Concerning
Regulations
That
Significantly
Affect
Energy
Supply,
Distribution,
or
Use
Today's
final
rule
is
not
subject
to
Executive
Order
13211
(
66
FR
28355,
May
22,
2001)
because
it
is
not
a
significant
regulatory
action
under
Executive
Order
12866.

directs
the

Rules
and
Regulations
use
available
and
applicable
voluntary
consensus
standards.
Today's
final
rule
involves
technical
standards.
The
EPA
cites
the
following
standards:
EPA
Methods
1,
1A,
2,
2A,
2C,
2D,
2F,
2G,
3,
3A,
3B,
4,
25A,
26,
26A,
311,
and
320.
Consistent
with
the
NTTAA,
EPA
conducted
searches
to
identify
voluntary
consensus
standards
in
addition
to
these
EPA
method/
performance
specifications.
No
applicable
voluntary
consensus
standards
were
identified
for
EPA
Methods
1A,
2A,
2D,
2F,
2G,
and
311.
The
search
and
review
results
have
been
documented
and
can
be
found
in
Docket
No.
OAR
 
2002
 
0088.
The
voluntary
consensus
standard
ASME
PTC
19
 
10
 
1981
 
Part
10,
``
Flue
and
Exhaust
Gas
Analyses,''
is
cited
in
the
rule
for
its
manual
methods
for
measuring
the
oxygen,
carbon
dioxide,
and
carbon
monoxide
content
of
exhaust
gas.
This
part
of
ASME
PTC
19
 
10
 
1981
 
Part
10
is
an
acceptable
alternative
to
Method
3B.
Also,
five
voluntary
consensus
standards:
ASTM
D1979
 
91,
ASTM
D3432
 
89,
ASTM
D4747
 
87,
ASTM
D4827
 
93,
and
ASTM
PS9
 
94
are
incorporated
by
reference
in
EPA
Method
311.
In
addition
to
the
voluntary
consensus
standards
EPA
cites
in
the
rule,
the
search
for
emissions
measurement
procedures
identified
13
other
voluntary
consensus
standards.
The
EPA
determined
that
ten
of
the
13
standards
identified
for
measuring
emissions
of
the
HAP
or
surrogates
subject
to
emission
standards
in
the
rule
were
impractical
alternatives
to
EPA
test
methods
for
the
purposes
of
the
rule.
Therefore,
EPA
does
not
intend
to
adopt
these
standards
for
this
purpose.
The
reasons
for
this
determination
for
the
ten
methods
are
discussed
in
the
docket.
Two
of
the
12
voluntary
consensus
standards
identified
in
this
search
were
not
available
at
the
time
the
review
was
conducted
for
the
purposes
of
the
rule
because
they
are
under
development
by
a
voluntary
consensus
body:
ASME/
BSR
MFC
13M,
``
Flow
Measurement
by
Velocity
Traverse,''
for
EPA
Method
2
(
and
possibly
1);
and
ASME/
BSR
MFC
12M,
``
Flow
in
Closed
Conduits
Using
Multiport
Averaging
Pitot
Primary
Flowmeters,''
for
EPA
Method
2.
The
voluntary
consensus
standard
ASTM
D6348
 
98,
``
Determination
of
Gaseous
Compounds
by
Extractive
Direct
Interface
Fourier
Transform
(
FTIR)
Spectroscopy,''
has
been
reviewed
by
the
EPA
as
a
potential
alternative
to
EPA
Method
320.
Suggested
revisions
to
ASTM
D6348
 
98
were
sent
to
ASTM
by
the
EPA
that
would
allow
the
EPA
to
accept
ASTM
D6348
 
98
as
an
acceptable
alternative.
The
ASTM
Subcommittee
D22
 
03
is
currently
undertaking
a
revision
of
ASTM
D6348
 
98.
Because
of
this,
we
are
not
citing
this
standard
as
a
acceptable
alternative
for
EPA
Method
320
in
the
rule
today.
However,
upon
successful
ASTM
balloting
and
demonstration
of
technical
equivalency
with
the
EPA
FTIR
methods,
the
revised
ASTM
standard
could
be
incorporated
by
reference
for
EPA
regulatory
applicability.
In
the
interim,
facilities
have
the
option
to
request
ASTM
D6348
 
98
as
an
alternative
test
method
under
40
CFR
63.7(
f)
and
63.8(

on
a
case­

Covers
§
63.9780
What
is
the
purpose
of
this
subpart?
This
subpart
establishes
national
emission
standards
for
hazardous
air
pollutants
(
NESHAP)
for
refractory
products
manufacturing
facilities.
This
subpart
also
establishes
requirements
to
demonstrate
initial
and
continuous
compliance
with
the
emission
limitations.

§
63.9782
Am
I
subject
to
this
subpart?
You
are
subject
to
this
subpart
if
you
own
or
operate
a
refractory
products
manufacturing
facility
that
is,
is
located
at,
or
is
part
of,
a
major
source
of
hazardous
air
pollutant
(
HAP)
emissions
according
to
the
criteria
in
paragraphs
(
a)
and
(
b)
of
this
section.
(
a)
A
refractory
products
manufacturing
facility
is
a
plant
site
that
manufactures
refractory
products
(
refractory
bricks,
refractory
shapes,
monolithics,
kiln
furniture,
crucibles,
and
other
materials
used
for
lining
furnaces
and
other
high
temperature
process
units),
as
defined
in
§
63.9824.
Refractory
products
manufacturing
facilities
typically
process
raw
material
by
crushing,
grinding,
and
screening;
mixing
the
processed
raw
materials
with
binders
and
other
additives;
forming
the
refractory
mix
into
shapes;
and
drying
and
firing
the
shapes.
(
b)
A
major
source
of
HAP
is
a
plant
site
that
emits
or
has
the
potential
to
emit
any
single
HAP
at
a
rate
of
9.07
megagrams
(
10
tons)
or
more
per
year
or
any
combination
of
HAP
at
a
rate
of
22.68
megagrams
(
25
tons)
or
more

Continuous
Compliance
Requirements
§
63.9808
How
do
I
monitor
and
collect
data
to
demonstrate
continuous
compliance?
(
a)
You
must
monitor
and
collect
data
according
to
this
section.
(
b)
At
all
times,
you
must
maintain
your
monitoring
systems
including,
but
not
limited
to,
maintaining
necessary
parts
for
routine
repairs
of
the
monitoring
equipment.
(
c)
Except
for,
as
applicable,
monitoring
system
malfunctions,
associated
repairs,
and
required
quality
assurance
or
quality
control
activities,
you
must
monitor
continuously
whenever
your
affected
process
unit
is
operating.
For
purposes
of
calculating
data
averages,
you
must
not
use
data
recorded
during
monitoring
system
malfunctions,
associated
repairs,
and
required
quality
assurance
or
quality
control
activities.
You
must
use
all
the
data
collected
during
all
other
periods
in
assessing
compliance.
A
monitoring
system
malfunction
is
any
sudden,
infrequent,
not
reasonably
preventable
failure
of
the
monitoring
system
to
provide
valid
data.
Monitoring
system
malfunctions
include
out
of
control
continuous
monitoring
systems
(
CMS),
such
as
a
CPMS.
Any
averaging
period
for
which
you
do
not
have
valid
monitoring
data
as
a
result
of
a
monitoring
system
malfunction
and
for
which
such
data
are
required
constitutes
a
deviation,
and
you
must
notify
the
Administrator
in
accordance
with
§
63.9814(
e).
Monitoring
system
failures
are
different
from
monitoring
system
malfunctions
in
that
they
are
caused
in
part
by
poor
maintenance
or
careless
operation.
Any
period
for
which
there
is
a
monitoring
system
failure
and
data
are
not
available
for
required
calculations
constitutes
a
deviation
and
you
must
notify
the
Administrator
in
accordance
with
§
63.9814(
e).

§
63.9810
How
do
I
demonstrate
continuous
compliance
with
the
emission
limits,
operating
limits,
and
work
practice
standards?
