National
Emissions
Standards
for
Hazardous
Air
Pollutants:
Reinforced
Plastic
Composites
Production
AGENCY:
Environmental
Protection
Agency
(
EPA).
ACTION:
Final
rule.

SUMMARY:
This
action
promulgates
national
emissions
standards
for
hazardous
air
pollutants
(
NESHAP)
for
new
and
existing
reinforced
plastic
composites
production
facilities.
The
NESHAP
regulate
production
and
ancillary
processes
used
to
manufacture
products
with
thermoset
resins
and
gel
coats.
Reinforced
plastic
composites
production
facilities
emit
hazardous
air
pollutants
(
HAP),
such
as
styrene,
methyl
methacrylate
(
MMA),
and
methylene
chloride
(
dichloromethane).
These
HAP
have
adverse
health
effects
including
headache,
fatigue,
depression,
irritation
of
skin,
eyes,
and
mucous
membranes.
Methylene
chloride
has
been
classified
as
a
probable
human
carcinogen.
The
NESHAP
will
implement
section
112(
d)
of
the
Clean
Air
Act
(
CAA)
by
requiring
all
major
sources
in
this
category
to
meet
HAP
emissions
standards
reflecting
the
application
of
the
maximum
achievable
control
technology
(
MACT).
We
estimate
the
final
NESHAP
will
reduce
nationwide
emissions
of
HAP
from
these
facilities
by
approximately
7,682
tons
per
year
(
tpy)
(
43
percent).

SUPPLEMENTARY
INFORMATION:
Docket.
We
have
established
an
official
public
docket
for
this
action
under
Docket
ID
No.

and
locate
documents
so
that
they
can
effectively
participate
in
the
rulemaking
process.
Along
with
the
proposed
and
promulgated
standards
and
their
preambles,
the

Introduction
A.
What
Is
the
Purpose
of
NESHAP?

The
purpose
of
the
final
NESHAP
is
to
protect
the
public
health
by
reducing
emissions
of
HAP
from
Reinforced
Plastic
Composite
Manufacturing
facilities.

B.
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.
Reinforced
Plastic
Composites
Production
was
included
on
the
initial
list
of
source
categories
published
on
July
16,
1992
(
57
FR
31576).
Major
sources
of
HAP
are
those
that
have
the
potential
to
emit
10
tpy
or
more
of
any
one
HAP
or
25
tpy
or
more
of
any
combination
of
HAP.
The
CAA
requires
NESHAP
to
reflect
the
maximum
degree
of
reduction
in
emissions
of
HAP
that
is
achievable.
This
level
of
control
is
commonly
referred
to
as
the
MACT.
The
MACT
floor
is
the
minimum
control
level
allowed
for
NESHAP.
This
concept
appears
in
section
112(
d)(
3)
of
the
CAA.
For
new
sources,
the
MACT
floor
cannot
be
less
stringent
than
the
HAP
emissions
control
that
is
achieved
in
practice
by
the
best­
controlled
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
HAP
emissions
limitation
achieved
by
the
best­
performing
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
cost
of
achieving
the
HAP
emissions
reductions,
any
non­
air
quality
health
and
environmental
impacts,
and
energy
requirements.

C.
What
Processes
and
Operations
Are
Included
in
the
Reinforced
Plastic
Composites
Production
Source
Category?
The
Reinforced
Plastic
Composites
Production
source
category
involves
the
production
of
plastic
products
from
cross­
linking
resins,
usually
in
combination
with
reinforcing
materials
and
inorganic
fillers.
These
products
may
have
an
outer
surface
produced
with
a
styrene­
containing
gel
coat.
The
production
of
products
that
do
not
contain
reinforcing
materials
is
also
included
in
this
category,
as
well
as
the
production
of
intermediate
compounds
that
are
later
used
to
make
the
final
plastic
products.
These
non­
reinforced
products
were
included
because
they
are
produced
using
the
same
types
of
resins,
have
similar
HAP
emissions
characteristics,
and
would
use
similar
HAP
emissions
controls.
This
source
category
is
limited
to
those
resins
and
gel
coats
which
contain
styrene,
either
by
itself
or
with
a
combination
of
other
monomers
or
solvents.
There
are
a
wide
variety
of
operations
that
use
styrene­
containing
resins
to
make
thermoset
plastics.
Such
manufacturing
operations
include
manual
resin
application,
mechanical
resin
application,
filament
application,
gel
coat
application,
compression/
injection
molding,
resin
transfer
molding,
centrifugal
casting,
continuous
lamination/
casting,
polymer
casting,
pultrusion,
bulk
molding
compound
(
BMC)
manufacturing,
and
sheet
molding
compound
(
SMC)
manufacturing.
There
are
also
ancillary
operations
such
as
cleaning,
mixing,
repair,
and
HAP­
containing
materials
storage,
that
occur
in
conjunction
with
these
manufacturing
operations.
Many
facilities
will
use
multiple
operations
in
manufacturing
their
products.
This
source
category
also
includes
some
repair
operations
that
take
place
at
a
manufacturing
facility,
such
as
repairs
of
parts
or
products
that
are
manufactured
at
the
same
facility
that
must
be
repaired
due
to
defects
or
damage
that
occur
during
manufacturing,
or
repairs
of
parts
that
were
originally
manufactured
at
that
location
and
have
been
returned
for
repair
due
to
defects
in
the
original
manufacture
or
damage
in
shipment.
No
other
types
of
repair
operations
are
included
in
this
source
category.
Facilities
that
perform
non­
routine
manufacture
of
reinforced
plastic
composites
parts
solely
to
replace
parts
of
a
reinforced
plastic
composite
product
that
has
been
in
use
are
not
considered
to
be
manufacturing
facilities,
and
repair
operations
at
these
types
of
facilities
are
not
part
of
this
source
category.
See
§
63.5935
of
the
final
rule
for
the
definition
of
nonroutine
manufacture.
We
believe
that
repair
operations
that
are
collocated
with
manufacturing
operations
that
originally
produce
the
reinforced
plastic
composites
being
repaired
use
the
same
materials
as
the
manufacturing
processes.
Repair
operations
that
are
not
collocated
may
use
different
materials
and
application
techniques.

Summary
of
the
Final
NESHAP
A.
What
Source
Categories
and
Subcategories
Are
Affected
by
the
Final
NESHAP?

Today's
final
rule
applies
to
the
Reinforced
Plastic
Composites
Production
source
category.
We
developed
subcategories
based
on
size
(
i.
e.,
tpy
of
HAP
emitted)
in
defining
the
new
source
MACT
floors.
These
subcategories
are
sources
that
emit
100
tpy
or
more
from
open
molding,
pultrusion,
centrifugal
casting,
continuous
lamination/
casting,
SMC
and
BMC
manufacturing,
and
mixing
operations;
and
all
other
new
sources.
The
new
source
MACT
floors
incorporate
add­
on
controls
for
sources
in
the
first
subcategory,
except
for
facilities
producing
large
parts,
and
pollution
prevention
for
other
new
sources.
The
floors
for
existing
sources
are
mainly
based
on
pollution
prevention,
not
add­
on
controls.
Where
floors
are
based
mainly
on
pollution­
prevention
control
techniques,
we
did
not
subcategorize
by
size.
However,
we
did
segregate
existing
sources
by
resin
application
technique,
resin
type,
and
final
products,
and
developed
separate
floors
for
each
process/
product
grouping.

B.
What
Are
the
Primary
Sources
of
HAP
Emissions
and
What
Are
the
Emissions?

The
primary
source
of
HAP
emissions
from
the
Reinforced
Plastic
Composites
Production
source
category
is
the
evaporation
of
styrene
and
other
organic
liquid
HAP
contained
in
the
resin
during
the
application
and/
or
curing
of
the
resin.
Since
styrene
participates
in
the
curing
reaction,
not
all
of
it
is
emitted.
Organic
HAP
emissions
also
occur
during
ancillary
operations
such
as
cleaning,
mixing,
repair,
and
HAP
containing
materials
storage.
Although
some
gel
coats
or
resins
may
contain
inorganic
HAP,
such
as
lead,
in
resin
solids
or
pigments,
we
have
no
data

Rules
and
Regulations
indicate
the
inorganic
HAP
are
emitted
from
the
production
process.
Therefore,
only
organic
HAP
are
addressed
by
the
final
NESHAP.
Total
baseline
HAP
emissions
from
the
Reinforced
Plastic
Composites
Production
source
category
are
approximately
18,000
tpy.
The
HAP
emissions
from
spray
lay­
up
and
gel
coating
constitute
approximately
52
percent
and
23
percent
of
the
total
baseline
HAP
emissions,
respectively.
The
remaining
HAP
emissions
are
primarily
from
hand
lay­
up/
bucket
and
tool
application,
compression
molding/
injection
molding,
filament
application,
SMC
manufacturing,
and
centrifugal
casting.

C.
What
Is
the
Affected
Source?
The
affected
source
is
the
combination
of
all
operations
regulated
under
these
standards
at
a
reinforced
plastic
composites
production
facility.
The
following
regulated
operations
are
typically
performed
at
reinforced
plastic
composites
production
facilities
and
are
part
of
the
affected
source:
open
molding,
closed
molding,
centrifugal
casting,
continuous
lamination/
casting,
polymer
casting,
pultrusion,
SMC
manufacturing,
equipment
cleaning,
mixing,
BMC
manufacturing,
repair,
and
storage
of
HAP­
containing
materials.
Repair
operations
are
also
included
as
part
of
the
affected
source
if
the
repair
is
made
to
a
part
manufactured
at
that
location.

D.
What
Are
the
HAP
Emissions
Limits,
Operating
Limits,
and
Other
Standards?
We
are
promulgating
the
requirements
of
the
final
NESHAP
in
the
form
of
HAP
emissions
limits
(
i.
e.,
HAP
emissions
factors,
mass
rate,
or
percent
reduction),
operating
limits,
and
work
practice
standards.
Work
practice
standards
include
design,
equipment,
work
practices,
and
operational
standards.
The
final
NESHAP
contain
a
HAP
emissions
threshold
that
distinguishes
between
sources
that
typically
can
meet
the
HAP
emissions
limits
using
pollution
prevention,
and
those
that
must
use
add­
on
controls.
This
threshold
is
called
the
``
100
tpy
threshold.''
For
existing
sources,
you
determine
if
you
are
below,
above,
or
equal
to
the
100
tpy
threshold
by
summing
all
HAP
emissions
from
centrifugal
casting
and
continuous
lamination/
casting
operations
at
the
source.
In
determining
HAP
emissions
from
centrifugal
casting
operations,
only
HAP
emissions
from
venting
of
the
centrifugal
casting
mold
during
spinning
and/
or
curing
are
considered.
The
HAP
emissions
that
occur
from
application
of
resin
or
gel
coat
to
an
open
centrifugal
casting
mold
are
considered
to
be
open
molding
HAP
emissions.
The
HAP
emissions
from
other
operations
or
processes
are
not
included
because
the
100
tpy
threshold
does
not
apply
to
other
operations
or
processes.
For
new
sources,
you
determine
if
you
are
below,
above,
or
equal
to
the
100
tpy
threshold
by
summing
all
HAP
emissions
from
open
molding,
pultrusion,
SMC
and
BMC
manufacturing,
centrifugal
casting,
continuous
lamination/
casting,
and
mixing
operations
at
the
source.
The
HAP
emissions
from
closed
molding,
cleaning,
repair
and
HAP­
containing
materials
storage
are
not
used
in
threshold
determinations.
In
determining
HAP
emissions
from
centrifugal
casting
operations,
only
HAP
emissions
from
venting
of
the
centrifugal
casting
mold
are
included.
The
HAP
emissions
that
occur
from
application
of
resin
or
gel
coat
to
an
open
centrifugal
casting
mold
are
considered
to
be
open
molding
HAP
emissions.
The
requirements
for
new
and
existing
sources
that
are
below
the
100
tpy
threshold
are
based
on
the
MACT
floor
level
of
control.
These
requirements
are

resin).
For
polymer
casting
mixing
operations,
containers
with
a
surface
area
of
500
square
inches
or
less
may
be
open
while
active
mixing
is
taking
place.

For
existing
sources
that
are
equal
to
or
above
the
100
tpy
HAP
emissions
threshold,
centrifugal
casting
and
continuous
lamination/
casting
operations
meet
an
above­
the­
floor
requirement
based
on
95
percent
control
of
HAP
emissions.
The
requirements
for
new
sources
that
are
equal
to
or
above
the
100
tpy
HAP
emissions
threshold
are
also
based
on
the
floor
level
of
control.
The
floor
level
of
control
for
these
sources
is
a
95
percent
reduction
of
HAP
emissions
for
open
molding,
pultrusion,
SMC
and
BMC
manufacturing,
centrifugal
casting,
continuous
lamination/
casting,
and
mixing
operations
with
one
exception.
For
open
molding
and
pultrusion
operations
at
new
sources
that
produce
large
parts,
the
floor
level
of
control
is
the
same
as
existing
sources
shown
in
the
previous
table.
All
other
operations
meet
the
requirements
shown
in
the
previous
table.
In
developing
final
requirements
for
reinforced
plastic
composites
affected
sources,
we
have
provided
an
alternative
format
where
possible.
For
example,
a
facility
meeting
a
95
percent
HAP
emissions
reduction
requirement
for
open
molding
processes
can
alternatively
meet
a
HAP
emissions
limit.
We
have
also
provided
alternatives
for
meeting
the
limits
for
continuous
lamination/
casting
and
SMC
manufacturing
operations.

E.
What
Are
the
HAP
Emissions
Factor
Equations
in
Table
1
to
Subpart
WWWW
of
Part
63,
and
How
Are
They
Used
in
the
Final
NESHAP?

Table
1
to
subpart
WWWW
of
part
63
presents
a
series
of
HAP
emissions
factor
equations
for
open
molding
and
centrifugal
casting
operations.
These
equations
are
specific
to
the
type
of
resin
and
gel
application
and
HAP
emissions
reduction
technique
used.
These
equations
allow
you
to
calculate
HAP
emissions
factors
based
on
HAP
content
and
application
method
for
each
material
that
you
use.
These
HAP
emissions
factors
are
then
averaged
and
compared
to
limits
in
the
final
standards
to
determine
if
your
open
molding
and
centrifugal
casting
operations
are
in
compliance.
The
HAP
emissions
factor
equations
for
open
molding
are
identical
to
HAP
emissions
equations
developed
by
the
composites
industry
called
the
Unified
Emissions
Factors
(
UEF)
as
they
existed
at
the
time
of
final
rule
development.
These
equations
can
also
be
combined
with
resin
and
gel
coat
use
to
determine
HAP
emissions
rates.
It
should
be
noted
that
although
the
equations
are
identical
to
the
UEF
at
the
time
the
rule
is
finalized,
for
purposes
of
compliance,
only
the
equations
actually
contained
in
Table
1
to
subpart
WWWW
of
part
63
may
be
used.

F.
When
Would
I
Need
To
Comply
With
the
Final
NESHAP?

We
are
requiring
that
all
existing
sources
comply
by
April
21,
2006.
Any
source
that
commenced
construction
after
August
2,
2001,
at
a
site
where
there
were
no
existing
reinforced
plastic
composite
operations
is
a
new
source.
New
affected
sources
that
are
now
in
operation
must
be
in
compliance
on
April
21,
2003.
New
affected
sources
that
startup
after
April
21,
2003
must
comply
upon
startup.
Existing
area
sources
that
increase
their
HAP
emissions
or
their
potential
to
emit
such
that
they
become
a
major
source
of
HAP
must
be
in
compliance
within
3
years
of
the
date
they
become
a
major
source.
New
area
sources
that
become
major
sources
of
HAP
must
comply
upon
becoming
a
major
source.
All
open
molding
and
centrifugal
casting
operations
that
comply
by
meeting
a
specified
HAP
emissions
limit
on
a
12­
month
rolling
average
will
have
1
year
from
the
compliance
date
to
demonstrate
compliance.
We
are
allowing
new
and
existing
facilities
3
years
to
comply
from
the
time
their
HAP
emissions
reach
or
exceed
the
applicability
thresholds
which
require
the
installation
of
add­
on
controls,
if
these
HAP
emissions
increases
occur
after
their
initial
compliance
date.
In
addition,
we
have
added
a
one­
time
exemption
for
facilities
that
exceed
the
100
tpy
threshold
due
to
unusual
circumstances.
Facilities
that
apply
for
this
exemption
and
subsequently
exceed
the
threshold
the
next
year,
must
comply
within
3
years
from
the
time
their
HAP
emissions
first
exceeded
the
threshold.
Because
this
is
a
one­
time
exemption,
an
exceedance
in
any
future
years
would
result
in
a
requirement
for
compliance
within
3
years
of
the
subsequent
exceedance.
G.
What
Are
the
Options
for
Demonstrating
Compliance?
Today's
final
NESHAP
provide
several
options
for
compliance
for
certain
operations.
We
are
providing
these
options
to
afford
industry
the
flexibility
to
decide
which
method
is
best
suited
for
each
particular
situation.
Operations
not
listed
in
this
section
have
only
one
option
for
demonstrating
compliance.
For
open
molding
and
centrifugal
casting
operations,
you
determine
compliance
with
the
HAP
emissions
limits
by
determining
HAP
emissions
factors
for
the
operations
at
your
facility,
and
comparing
your
HAP
emissions
factors
to
the
appropriate
HAP
emission
limits
for
each
open
molding
and
centrifugal
casting
operation.
To
determine
your
HAP
emissions
factor
you
may
use
the
HAP
emissions
factor
equations
in
Table
1
to
subpart
WWWW,
or
HAP
emissions
factors
based
on
facility
HAP
emissions
testing.
For
open
molding
operations
at
existing
and
new
sources,
the
final
rule
allows
you
to
choose
to
comply
by
meeting
the
individual
HAP
emissions
limits
shown
in
Table
3
to
subpart
WWWW
of
part
63
for
each
operation
at
your
affected
source,
or
by
meeting
the
weighted
average
HAP
emissions
limit
for
all
open
molding
operations
at
your
affected
source.
In
addition,
if
you
produce
parts
with
any
combination
of
manual
resin
application,
mechanical
resin
application,
filament
application,
or
centrifugal
casting
operations
at
your
affected
source,
you
can
comply
using
the
an
alternative
method
shown
in
Table
7
to
subpart
WWWW
of
part
63.
You
determine
the
highest
allowable
HAP
resin
for
each
individual
operation
from
Table
3
to
subpart
WWWW
of
part
63.
This
same
resin
can
then
be
used
in
all
open
molding
and
centrifugal
casting
operations
as
shown
in
Table
7
to
subpart
WWWW
of
part
63.
For
open
molding
and
centrifugal
casting
operations
where
the
rule
would
require
you
to
meet
a
percent
reduction,
you
could
use
an
add­
on
control
device
to
achieve
the
required
reduction,
or
you
may
choose
to
meet
a
HAP
emissions
limit
that
corresponds
to
that
particular
operation's
percent
reduction.
For
continuous
lamination/
casting
operations
at
existing
and
new
sources,
we
are
allowing
you
to
demonstrate
that
each
continuous
casting
line

or
§
63.5805(

or
(

of
the

Alternatively,
you
can
average
all
your
continuous
casting
and
continuous
lamination
lines
together
and
demonstrate
that
they
meet
the
appropriate
standard.
An
additional
alternative
for
sources
that
emit
less
than
the
100
tpy
threshold
would
be
to
capture
your
HAP
emissions
from
your
wet­
out
area
in
a
permanent
total
enclosure
that
meets
EPA's
criteria,
as
specified
in
Method
204
of
appendix
M
of
40
CFR
part
51,
and
vent
the
captured
wet­
out
HAP
emissions
through
a
closed
vent
system
to
a
control
device
achieving
95
percent
reduction
of
HAP
emissions.
Under
the
final
rule,
these
alternatives
can
be
used
in
combination
to
demonstrate
compliance.
The
standards
for
continuous
lamination/
casting
operations
are
expressed
as
a
percent
reduction
of
HAP
emissions.
As
an
alternative,
facilities
can
elect
to
meet
a
HAP
emissions
limit.
For
existing
and
new
pultrusion
operations,
you
can
capture
and
vent
your
HAP
emissions
to
a
control
device
that
achieves
the
required
percent
reduction
of
HAP
emissions.
For
all
existing
sources
and
for
new
sources
that
emit
less
than
the
100
tpy
threshold,
you
may
use
a
wet­
area
enclosure
with
a
resin
drip
collection
system,
direct
die
injection
or
preform
injection
systems
that
meet
the
criteria
specified
in
§
63.5830
of
the
final
rule
to
meet
the
60
percent
HAP
emissions
reduction
requirement.
For
pultrusion
machines
that
produce
parts
with
1000
or
more
reinforcements
and
a
cross
sectional
area
of
60
inches
or
more,
you
must
implement
the
work
practice
standards
in
Table
4
to
subpart
WWWW
of
part
63.
For
SMC
manufacturing
operations
at
new
sources
that
exceed
the
100
tpy

we
allow
facilities
to
meet
a
95

or
the
HAP

limit
specified
in
Table

H.
What
Are
the
Testing
and
Initial
Compliance
Requirements?
We
are
requiring
you
to
conduct
an
initial
performance
test
using
specified
EPA
test
methods
on
all
affected
sources
which
use
a
control
device
to
achieve
compliance.
You
must
test
at
the
inlet
and
outlet
of
the
control
device
and
using
these
results,
calculate
a
percent
reduction.
We
are
also
requiring
you
to
conduct
a
design
evaluation,
as
specified
by
EPA
Method
204
of
appendix
M
of
40
CFR
part
51,
if
you
use
permanent
total
enclosures
to
capture
HAP
emissions.
If
your
enclosure
does
not
meet
the
requirements
for
a
permanent
total
enclosure,
you
must
test
the
enclosure
to
determine
the
capture
efficiency
by
EPA
Methods
204B
through
E
of
appendix
M
of
40
CFR
part
51
or
an
alternative
method
that
meets
the
data
quality
objectives
and
lower
confidence
limit
approaches
contained
in
40
CFR
part
63,
subpart
KK.
Test
runs
for
EPA
Methods
204B
through
E
or
alternative
test
methods
must
be
at
least
3
hours.
Prior
to
the
initial
performance
test,
owners
and
operators
of
affected
sources
would
be
required
to
install
the
parameter
monitoring
equipment
to
be
used
to
demonstrate
compliance
with
the
operating
limits.
During
the
initial
performance
test,
the
owners
and
operators
would
use
the
parameter
monitoring
equipment
to
establish
operating
parameter
limits.

I.
What
Are
the
Continuous
Compliance
Requirements?
If
you
use
an
add­
on
control
device,
we
are
requiring
that
you
monitor
and
record
the
operating
parameters
established
during
the
initial
performance
test,
and
calculate
average
operating
parameter
values
averaged
over
the
period
of
time
specified
in
the
final
NESHAP
to
demonstrate
continuous
compliance
with
the
operating
limits.
If
you
use
the
HAP
emissions
equations
in
Table
1
to
subpart
WWWW
of
part
63
to
demonstrate
that
you
are
maintaining
a
HAP
emissions
factor
less
than
or
equal
to
the
appropriate
HAP
emissions
limit
listed
in
the
final
NESHAP,
we
are
requiring
that
you
calculate
the
HAP
emissions
factor
one
time
if
the
resins
or
gel
coats
used
in
the
operation
remain
the
same,
or
if
all
the
resins
and
gel
coats
used
individually
meet
the
applicable
HAP
emissions
limit.
You
are
required
to
calculate
HAP
emissions
factors
on
a
12­
month
rolling
average
each
month
if
the
resin
or
gel
coat
varies
between
operations
or
varies
over
time,
and
not
all
resins
or
gel
coats
taken
individually
meet
the
required
HAP
emissions
limit.
If
you
are
complying
with
work
practice
standards,
we
are
requiring
that
you
demonstrate
compliance
with
the
work
practice
standards
in
the
final
NESHAP
by
performing
the
necessary
work
practices
and
by
keeping
a
record
certifying
that
you
are
in
compliance
with
the
work
practices.

J.
What
Are
the
Notification,
Reporting,
and
Recordkeeping
Requirements?
We
are
requiring
that
you
submit
Initial
Notification,
Notification
of
Performance
Tests,
and
Notification
of
Compliance
Status
reports
by
the
specified
dates
in
the
final
NESHAP,
which
may
vary
depending
on
whether
the
affected
source
is
new
or
existing.
You
are
also
required
to
submit
semiannual
compliance
reports.
If
you
take
action
that
is
inconsistent
with
your
approved
startup,
shutdown,
and
malfunction
(
SSM)
plan,
then
you
would
need
to
submit
SSM
reports
within
2
days
of
starting
such
action,
and
within
7
days
of
ending
such
action.
We
are
requiring
that
you
keep
a
copy
of
each
notification
and
report,
along
with
supporting
documentation
for
5
years.
Of
this
time,
the
2
most
recent
years
must
be
on­
site.
You
must
keep
records
related
to
SSM,
records
of
performance
tests,
and
records
for
each
continuous
parameter
monitoring
system.
Under
the
final
rule,
if
you
must
comply
with
the
work
practice
standards,
you
also
need
to
keep
records
certifying
that
you
are
in
compliance
with
the
work
practices
for
5
years.
If
you
use
the
HAP
emissions
factor
equations
to
demonstrate
compliance,
you
must
keep
all
data,
assumptions,
and
calculations
used
to
determine
your
HAP
emissions
factors.
For
new
and
existing
continuous
lamination/
casting
operations,
you
also
must
keep
the
following
records
when
complying
with
the
percent
reduction
or
pound
per
ton
requirements:
All
data,
assumptions,
and
calculations
used
to
determine
the
percent
reduction
or
pounds
per
ton,
as
applicable;
a
brief
description
of
the
rationale
for
the
assignment
of
an
equation
or
factor
to
each
formula;
all
data,
assumptions,
and
calculations
used
to
derive
facility­
specific
HAP
emissions
estimations
and
factors;
identification
and
rationale
for
the
worst­
case
scenario;
and
documentation
that
the
appropriate
regulatory
agency
has
approved
all
HAP
emissions
estimation
equations
and
factors.

Summary
of
Environmental,
Energy,
and
Economic
Impacts
A.
What
Facilities
Are
Affected
by
the
Final
NESHAP?

There
are
approximately
435
existing
facilities
manufacturing
reinforced
plastic
composites
that
are
major
sources
and
subject
to
the
final
NESHAP.
The
rate
of
growth
for
the
reinforced
plastic
composites
industry
is
estimated
to
be
84
new
facilities
over
the
next
5
years.

B.
What
Are
the
Air
Quality
Impacts?

The
1997
baseline
HAP
emissions
from
the
reinforced
plastic
composites
industry
are
approximately
18,000
tpy.
The
final
NESHAP
will
reduce

Rules
and
Regulations
from
existing
sources
by
7,682
tpy,
a
reduction
of
43
percent.
The
final
NESHAP
will
result
in
small
increases
in
other
air
pollution
emissions
from
combustion
devices
that
will
be
installed
in
the
next
5
years
to
comply
with
today's
final
rule.
These
increases
result
both
from
the
combustion
device
directly,
and
from
the
electrical
generating
plants
used
to
generate
the
electricity
necessary
to
operate
the
add­
on
controls
and
associated
air
handling
equipment.
These
emissions
are
estimated
to
be
2.3
tpy
of
sulfur
oxides
(
SOx),
3.0
tpy
of
nitrogen
oxides
(
NOX),
4.9
tpy
of
carbon
monoxide
(
CO),
and
0.1
tpy
of
particulate
matter
(
PM)
emissions.

C.
What
Are
the
Water
Quality
Impacts?
We
estimate
that
the
final
NESHAP
will
have
no
adverse
water
quality
impacts.
We
do
not
expect
anyone
to
comply
by
using
add­
on
control
devices
or
process
modifications
that
would
generate
wastewater.

D.
What
Are
the
Solid
and
Hazardous
Waste
Impacts?
We
estimate
that
the
final
NESHAP
will
decrease
the
amount
of
solid
waste
generated
by
the
reinforced
plastic
composites
industry
by
approximately
2,650
tpy.
The
decrease
in
solid
waste
is
directly
related
to
switching
to
nonatomized
resin
application
equipment
(
i.
e.,
flowcoaters
and
resin
rollers).
Switching
to
nonatomized
resin
application
equipment
results
in
a
decrease
in
overspray
because
of
a
greater
transfer
efficiency
of
resin
to
the
part
being
manufactured.
A
decrease
in
resin
overspray
consequently
reduces
the
amount
of
waste
from
disposable
floor
coverings,
cured
resin
waste,
and
personal
protective
equipment
(
PPE)
for
workers.
Disposable
floor
coverings
are
replaced
on
a
periodic
basis
to
prevent
resin
buildup
on
the
floor.
We
estimate
that
solid
waste
generation
of
floor
coverings
will
decrease
by
approximately
620
tpy,
and
that
cured
resin
solid
waste
will
decrease
by
approximately
2,030
tpy.
We
project
that
the
decreased
overspray
from
nonatomized
resin
application
equipment
will
result
in
a
decreased
usage
of
PPE,
which
also
consequently
reduces
the
amount
of
solid
waste.
When
using
nonatomized
resin
application
equipment,
workers
typically
wear
less
PPE
than
when
using
atomized
spray
guns
because
of
the
reduced
presence
of
resin
aerosols
and
lower
styrene
levels
in
the
workplace.
Because
we
did
not
have
information
on
the
many
different
types
of
PPE
currently
used,
we
did
not
estimate
this
decrease
in
solid
waste.
Some
facilities
that
switch
from
atomized
to
nonatomized
spray
guns
may
have
a
small
increase
of
hazardous
waste
from
the
used
nonatomized
spray
gun
cleaning
solvents.
However,
most
facilities
would
not
see
an
increase
under
the
final
rule,
and
the
overall
impact
on
the
industry
will
be
small
relative
to
the
solid
waste
reductions.
Nearly
all
nonatomized
spray
guns
require
resin
and
catalyst
to
be
mixed
inside
the
gun
(
internal­
mix)
and
must
be
flushed
when
work
is
stopped
for
more
than
a
few
minutes.
External­
mix
spray
guns
do
not
need
to
be
flushed
because
resin
is
mixed
with
catalyst
outside
the
gun.
Facilities
that
switch
from
external­
mix
to
nonatomized
spray
guns
will
use
more
solvent.
Solvent
usage
should
not
change
at
facilities
switching
from
internal­
mix
spray
guns
to
nonatomized
spray
guns.
The
most
common
flushing
solvents
are
acetone
and
water­
based
emulsifiers.
Only
a
couple
of
ounces
of
solvent
are
typically
needed
to
flush
the
mixing
chamber
and
nozzle
of
internal­
mix
spray
guns.
We
do
not
have
adequate
data
to
predict
the
potential
solvent
waste
impact
from
switching
to
nonatomized
spray
guns.
The
magnitude
of
the
impact
depends
on
the
type
of
gun
currently
used
(
internal­
or
externalmix
the
frequency
of
flushing,
and
the
type
of
solvent
used.
However,
because
of
the
small
amount
of
solvent
used,
and
since
most
is
allowed
to
evaporate,
we
believe
the
overall
solvent
waste
increase
will
be
small
compared
to
the
solid
waste
reductions.

E.
What
Are
the
Energy
Impacts?
Energy
impacts
result
from
the
final
NESHAP
because
some
facilities
will
be
required
to
install
add­
on
controls
to
meet
certain
HAP
emissions
limits
or
percent
reduction
requirements.
We
anticipate
that
these
controls
will
be
concentrator/
oxidizer
systems
or
thermal
oxidizers.
These
controls
increase
energy
requirements
in
two
ways.
First,
all
reinforced
plastic
composites
facilities
must
ventilate
work
areas
to
maintain
worker
styrene
exposure
within
acceptable
limits.
The
ventilation
systems
typically
exhaust
air
directly
to
the
atmosphere.
When
an
add­
on
control
device
is
added
to
control
HAP
emissions,
it
creates
an
additional
pressure
drop
for
the
ventilation
system
which,
in
turn,
means
that
more
electricity
is
required
to
operate
system
fans
and
to
operate
the
control
device
itself.
Second,
fuel
(
usually
natural
gas)
is
required
to
supplement
the
oxidizer
combustion
process.
We
determined
that
the
overall
energy
demand
for
operations
in
the
Reinforced
Plastic
Composites
Production
source
category
could
increase
by
10
million
standard
cubic
feet
per
year
of
natural
gas,
and
0.6
million
kilowatt
hours
of
electricity
per
year
as
a
result
of
the
final
rule.
We
determined
this
net
increase
based
on
the
additional
energy
demand
for
control
devices
installed
to
meet
the
final
standards.
No
information
for
comparison
is
available
on
the
baseline
energy
consumption
for
this
source
category.

F.
What
Are
the
Cost
Impacts?
We
have
estimated
the
industrywide
capital
costs
for
HAP
emissions
control
equipment,
including
equipment
such
as
open
container
covers,
resin
bath
enclosures,
capture
systems,
and
control
devices
as
$
12.6
million
for
the
435
existing
sources
and
$
22.8
million
for
the
84
new
sources.
The
capital
costs
include
the
costs
to
purchase
and
install
the
control
equipment.
We
have
estimated
the
industrywide
annual
costs
of
the
final
rule
are
$
21.5
million
per
year
for
the
435
existing
sources
and
$
7.7
million
for
the
84
new
sources.
Annual
costs
include
fixed
annual
costs,
such
as
reporting,
recordkeeping
and
capital
amortization,
and
variable
annual
costs
such
as
natural
gas.
The
estimated
average
cost
of
the
final
rule
is
$
2,800
per
ton
of
HAP
emissions
reductions
for
existing
sources
and
$
5,560
per
ton
of
HAP
emissions
reductions
for
new
sources.

G.
What
Are
the
Economic
Impacts?
We
conducted
a
detailed
economic
impact
analysis
to
determine
the
market­
and
industry­
level
impacts
associated
with
the
final
rule.
We
expect
the
aggregate
price
increase
for
reinforced
plastic
composites
would
be
only
0.7
percent,
or
$
0.03
per
pound,
as
a
result
of
the
final
rule.
We
project
that
directly
affected
producers
would
reduce
total
production
by
1.7
percent,
while
producers
not
directly
affected
would
increase
their
production
by
0.7
percent.
Markets
for
reinforced
plastic
composites
used
in
corrosion­
resistant
products
are
expected
to
be
more
heavily
impacted
with
price
increases
of
roughly
1.6
percent
and
reductions
in
directly
affected
domestic
production
of
almost
5
percent.
The
reason
for
more
significant
impacts
in
the
corrosionresistant
market
is
that
facilities
in
this
market
have
higher
average
per­
unit
variable
compliance
costs.
Corrosionresistant
product
variable
compliance
costs
are
$
0.13
per
pound
of
product
versus
an
industry
average
of
$
0.06
per
pound.
In
terms
of
industry
impacts,
we
analyzed
impacts
for
captive
producers
and
merchant
producers.

and
Regulations
producers
make
composites
for
use
by
another
part
of
their
company
in
a
larger
product.
Merchant
producers
sell
their
products
on
the
open
market,
either
to
consumers
or
other
businesses.
In
our
analysis,
captive
producers
of
reinforced
plastic
composites
are
expected
to
fully
absorb
their
compliance
costs,
which
is
a
conservative
approach.
We
assess
impacts
as
if
captive
producers
are
viewed
as
a
profit
center
like
a
merchant
producer
but
unable
to
pass
on
costs.
This
is
done
in
lieu
of
an
analysis
attempting
to
estimate
cost­
pass
through
for
the
myriad
of
final
products
that
use
reinforced
plastics.
We
assume
merchant
producers
will
attempt
to
pass
through
costs
to
their
customers.
Through
the
market
impacts
described
above,
the
final
NESHAP
create
both
gainers
and
losers
within
the
merchant
segment.
Some
merchant
facilities
are
projected
to
experience
profit
increases
with
the
final
rule;
however,
the
majority
that
continue
operating
are
projected
to
lose
profits.
The
economic
impact
analysis
indicates
that
36
out
of
301
merchant
facilities
(
12
percent)
and
89
out
of
466
product
lines
(
19
percent)
at
these
facilities
are
at
risk
of
closure
because
of
the
final
NESHAP.
These
facilities
are
believed
to
be
small
businesses.
Note
that
this
number
is
slightly
higher
than
the
estimate
of
facility
closure
at
proposal,
which
was
10
percent.
This
change
is
not
due
to
any
change
in
stringency
of
the
final
rule
as
applied
to
small
businesses.
It
is
due
the
reduction
in
stringency
of
the
final
rule
for
large
sources.
More
information
on
the
measures
we
have
taken
to
minimize
the
small
business
impacts
may
be
found
in
the
Regulatory
Flexibility
Act
discussion
in
this
preamble.
Furthermore,
the
analysis
indicates
that
ten
of
the
133
captive
facilities
(
7.5
percent)
may
be
at
risk
of
closure
if
unable
to
pass
on
costs
to
their
customers.
Based
on
the
market
analysis,
the
annual
social
costs
of
the
final
rule
are
projected
to
be
$
19.9
million.
The
social
costs
are
slightly
less
than
the
engineering
cost
estimate
of
$
21.5
million
because
producers
pass
on
a
portion
of
these
costs
to
consumers
through
price
increases
in
an
effort
to
reduce
their
regulatory
burden.
These
costs
are
distributed
across
the
many
consumers
and
producers
of
reinforced
plastic
composites.
Directly
affected
producers,
in
aggregate,
are
expected
to
lose
$
6.2
million
annually
in
profits,
with
those
not
subject
to
the
final
NESHAP
gaining
$
18
million.
The
consumers
of
reinforced
plastic
composites
are
expected
to
lose
$
31.7
million
due
to
higher
prices
and
lower
consumption
levels
associated
with
the
final
NESHAP.

IV.
Summary
of
Changes
Since
Proposal
A.
Above­
the­
Floor
Capture
and
Control
Requirements
for
Existing
Sources
In
the
proposed
rule,
existing
facilities
that
are
a
small
business
as
defined
by
the
Small
Business
Administration
(
SBA)
regulations
at
13
CFR
121.201,
and
that
emitted
250
tpy
or
more
of
HAP,
or
existing
facilities
that
are
not
a
small
business
and
emitted
100
tpy
or
more
of
HAP,
from
the
combination
of
all
open
molding,
centrifugal
casting,
continuous
lamination/
casting,
pultrusion,
SMC
manufacturing,
mixing,
and
BMC
manufacturing
operations,
were
required
to
reduce
the
total
HAP
emissions
from
these
operations
by
at
least
95
percent
by
weight.
In
the
final
rule,
this
requirement
now
only
applies
to
centrifugal
casting
and
continuous
lamination/
casting
operations,
and
the
threshold
has
been
changed
to
100
tpy
for
both
large
and
small
businesses.
This
reduced
the
number
of
facilities
we
estimated
would
have
to
meet
an
abovethe
floor
requirement
from
34
to
3,
reduced
the
industry
annualized
costs
of
the
final
NESHAP
from
$
26.0
million
per
year
to
$
21.5
million
per
year,
and
reduced
the
HAP
emissions
reduction
estimate
from
14,500
to
7,700
tpy.
In
addition,
for
centrifugal
casting,
the
percent
reduction
requirement
only
applies
to
HAP
emissions
that
are
vented
from
the
closed
centrifugal
casting
mold.
It
does
not
apply
to
HAP
emissions
that
occur
from
other
operations
such
as
pouring
or
spraying
resin
into
a
centrifugal
casting
mold
while
it
is
open.

B.
Replacing
the
Point
Value
Equations
With
HAP
Emissions
Factor
Equations
Based
on
the
Unified
Emissions
Factors,
and
Changes
to
Centrifugal
Casting
HAP
Emissions
Factors
In
the
proposed
rule,
we
used
a
group
of
equations
called
point
value
equations
to
determine
surrogate
HAP
emissions
factors.
These
factors
were
then
used
to
rank
existing
facilities
to
determine
existing
source
MACT
floors
for
open
molding
operations.
However,
we
specified
that
the
point
value
equations
were
not
considered
HAP
emissions
factors
and,
therefore,
should
not
be
used
for
HAP
emissions
reporting.
This
resulted
in
the
potential
for
facilities
to
have
to
use
two
different
sets
of
equations
for
HAP
emissions
reporting
and
MACT
compliance
determinations.
In
the
final
rule,
we
have
eliminated
the
point
value
equations
and
replaced
them
with
HAP
emissions
factor
equations
that
are
identical
to
HAP
emissions
factor
equations
that
are
being
used
in
this
industry
for
HAP
emissions
calculations,
called
the
Unified
Emissions
Factors.
Therefore,
facilities
now
will
have
the
same
equations
for
MACT
compliance
determinations
and
HAP
emissions
calculations
for
HAP
emissions
reports.
For
centrifugal
casting,
we
have
retained
the
HAP
emissions
factor
equation
in
the
proposed
rule
for
sources
that
blow
heated
air
through
the
mold
during
spinning
and
curing.
For
other
centrifugal
casters,
we
have
created
a
new
HAP
emissions
factor
equation
based
on
more
recent
information.
This
new
HAP
emissions
factor
significantly
changes
the
numerical
value
of
the
floor
(
pounds
of
HAP
emissions
per
ton
of
resin
used)
from
the
value
in
the
proposed
rule.
However,
it
did
not
change
the
floor
facility
or
the
level
of
control
a
facility
would
need
to
meet
the
floor.
These
new
HAP
emissions
factor
equations
were
also
used
to
re­
rank
existing
facilities
to
establish
the
floor
level
of
control
for
existing
sources.
Though
this
change
did
result
in
different
floor
values
in
lb/
ton,
it
did
not
change
the
level
of
control
actually
required
to
meet
the
floor.
However,
as
discussed
below,
our
reanalysis
did
result
in
changes
to
some
floors
for
other
reasons.

C.
MACT
Floors
for
Existing
Sources
There
are
several
changes
to
the
MACT
floors
for
existing
sources,
and
for
new
sources
that
emit
less
than
100
tpy
for
the
combination
of
all
open
molding,
centrifugal
casting,
pultrusion,
SMC
and
BMC
manufacturing,
mixing,
and
continuous
lamination/
casting
operations.
These
changes
were
a
result
of
facilities
submitting
additional
data
that
indicated
our
original
analysis
of
their
facility
HAP
emissions
factors
were
in
error,
or
out
of
date.
For
noncorrosion­
resistant
resins
applied
using
mechanical
application,
the
proposed
rule
had
different
floors
for
filled
and
unfilled
resins.
The
reason
for
separating
filled
and
unfilled
resins
was
that
at
the
time
of
proposal,
nonatomized
resin
application
techniques
were
not
available
for
filled
resins.
Since
proposal,
filled
resins
now
can
be
applied
using
nonatomized
spray.
Therefore,
we
now
have
combined
the
two
process/
product
groupings
into
one.
Also,

facilities

this

grouping
provided
revised
data.
As
a
result,
the
floor
level
of
control
for
noncorrosion­
resistant
resins
using
mechanical
application
is
a
HAP
emissions
limit
of
87
lb/
ton.
This
limit
requires
a
resin
with
no
more
than
38.4
percent
HAP
applied
using
nonatomized
mechanical
resin
application
techniques.
At
proposal,
facilities
could
use
a
42.8
percent
resin
(
filled)
or
a
38
percent
HAP
(
unfilled)
resin
and
nonatomized
mechanical
resin
application.
For
mechanical
corrosion­
resistant
resin
application,
the
revised
floor
is
a
HAP
emissions
limit
of
112
lb/
ton.
This
limit
requires
a
resin
with
no
more
that
46.2
percent
HAP
and
nonatomized
mechanical
resin
application.
At
proposal,
a
resin
HAP
content
of
up
to
48.3
percent
was
allowed
if
nonatomized
mechanical
resin
application
was
used.
For
manual
application
of
tooling
resin,
the
revised
floor
is
157
lb/
ton.
This
allows
a
resin
HAP
content
of
45.9
percent
or
less.
At
proposal,
the
maximum
allowable
HAP
content
was
39.9
percent.
For
tooling
gel
coat
the
revised
floor
is
437
lb/
ton.
This
limits
gel
coat
HAP
content
to
40
percent
of
less.
At
proposal,
the
limit
was
38
percent
or
less.
For
SMC
manufacturing,
the
work
practices
required
in
the
proposed
rule
were
use
of
nylon
film,
folding
the
edges
of
the
film,
and
covering
the
doctor
box.
In
the
final
rule,
the
requirements
are
a
covered
resin
transport
system
to
the
doctor
box
and
the
use
of
nylon­
containing
film.
For
pultrusion
operations
producing
parts
with
1000
or
more
reinforcements
and
a
cross
sectional
area
of
60
inches
or
more,
we
have
changed
the
floor
from
60
percent
HAP
emissions
reduction
to
a
work
practice
of
air
flow
management.
In
addition,
we
established
three
new
floors
for
speciality
resins
and
gel
coats.
These
are
shrinkage­
controlled
resins,
fire
retardant
gel
coats,
and
high
performance
gel
coats.
These
speciality
products
were
identified
from
comments
received
on
the
proposed
rule.
The
new
floors
are
shown
in
Table
3
to
subpart
WWWW
of
part
63.

D.
Cleaning
In
the
proposed
rule,
we
required
that
cleaning
materials
contain
no
HAP
unless
cleaning
cured
resin
from
application
equipment.
In
the
final
rule,
we
have
modified
that
requirement
to
allow
HAP­
containing
cleaners
to
be
used
in
closed
systems
such
as
closed
tanks,
and
resin
and
gel
coat
delivery
systems.
E.
Compression/
Injection
Molding
In
the
proposed
rule,
we
required
that
only
one
resin
charge
be
uncovered
at
a
time.
We
have
clarified
this
requirement
for
the
final
rule
to
reflect
that
one
charge
may
actually
have
to
fill
multiple
molds.
Also,
we
added
a
provision
to
allow
the
use
of
automated
loaders
and
slitters.
We
also
clarified
that
paste
added
to
the
mold
and
inmold
surface
coatings
are
considered
part
of
the
closed
molding
operation.

F.
Averaging
Provisions
In
the
proposed
rule,
we
allowed
facilities
to
average
across
all
open
molding
operations
and
all
centrifugal
casting
operations.
The
average
was
based
on
a
12­
month
rolling
average
calculated
monthly.
In
determining
compliance,
the
average
for
each
month
was
calculated
and
then
the
monthly
averages
were
averaged
over
a
12­
month
period.
In
the
final
rule,
the
12­
month
average
is
based
on
a
weighted
HAP
emissions
factor
calculated
from
total
resin
and
gel
coat
use
over
the
12­
month
period.
This
method
will
provide
a
more
accurate
value
for
the
actual
HAP
emissions,
in
lb/
ton,
that
the
facility
produced
in
the
previous
12
months.
In
the
proposed
rule,
we
did
not
allow
pultrusion
lines
to
average;
each
pultrusion
machine
had
to
meet
the
60
percent
reduction
requirement
for
existing
sources.
In
the
final
rule,
we
allow
facilities
to
over
control
some
lines,
and
under
control
(
or
leave
uncontrolled)
others,
as
long
as
the
average
reduction
for
all
lines
combined
is
60
percent
weighted
by
resin
use.
Also,
we
are
allowing
facilities
to
average
the
time
that
wet
area
enclosure
covers
are
open
across
lines.

G.
Pultrusion
Compliance
Options
In
the
proposed
rule,
we
allowed
pultrusion
operations
to
use
direct
die
injection
as
a
compliance
alternative
to
meet
the
95
percent
capture
and
control
requirement.
In
the
final
rule,
we
are
removing
direct
die
injection
as
a
compliance
alternative
because,
based
on
industry
data,
it
does
not
achieve
95
percent
HAP
emissions
reduction.
We
still
allow
direct
die
injection
as
a
compliance
option
to
meet
the
60
percent
HAP
emissions
reduction
requirement.
We
have
also
added
another
compliance
option,
preform
injection,
to
meet
a
60
percent
HAP
emissions
reduction.
We
have
also
added
another
compliance
option,
airflow
management
work
practices,
for
pultrusion
machines
that
produce
large
parts
as
set
forth
in
Table
4
to
subpart
WWWW
of
part
63.
H.
Applicability
We
made
a
number
of
changes
dealing
with
rule
applicability.
First,
we
expanded
the
list
of
specific
operations
that
are
part
of
the
source
category,
but
are
not
subject
to
any
control,
reporting,
or
recordkeeping
requirements.
These
operations
include
application
of
mold
sealing
and
release
agents,
mold
stripping
and
cleaning,
repair
of
previously
manufactured
parts
that
is
unrelated
to
collocated
manufacturing
operations,
personal
activities
that
are
not
part
of
the
manufacturing
operations
(
such
as
hobby
shops
on
military
bases),
prepreg
materials
as
defined
in
§
63.5935
of
the
final
rule,
non­
gel
coat
surface
coatings,
repair
or
production
materials
that
do
not
contain
resin
or
gel
coat,
and
research
and
development
(
R&
D)
operations
as
defined
in
section
112(
c)(
7)
of
the
CAA.
In
addition,
we
exempted
any
facility
that
uses
less
than
1.2
tpy
of
resin
and
gel
coat,
and
R&
D
facilities
and
operations
at
manufacturing
facilities.
The
rationale
for
these
changes
is
discussed
in
the
responses
to
major
comments
section.

I.
Potential
Overlap
With
the
Boat
Manufacturing
NESHAP
(
40
CFR
Part
63,
Subpart
VVVV)

In
the
proposed
rule,
we
were
silent
concerning
situations
where
a
facility
could
be
subject
to
both
the
Boat
Manufacturing
NESHAP,
40
CFR
part
63,
subpart
VVVV,
and
the
Reinforced
Plastic
Composites
NESHAP.
In
today's
final
rule,
we
have
added
§
63.5787
to
clarify
which
subpart
applies.
In
general,
if
your
facility
makes
boat
hulls
and
decks,
or
molds
for
boat
hulls
and
decks,
then
40
CFR
part
63,
subpart
VVVV,
applies
to
you.
If
40
CFR
part
63,
subpart
VVVV,
does
not
apply
to
you,
and
you
meet
the
applicability
criteria
in
§
63.5785
of
the
final
rule,
then
the
Reinforced
Plastics
Composites
NESHAP
apply.
If
you
are
subject
to
40
CFR
part
63,
subpart
VVVV,
and
also
make
reinforced
plastic
composite
parts
that
are
not
used
in
boat
manufacture,
then
both
40
CFR
part
63,
subpart
VVVV,
and
the
Reinforced
Plastic
Composites
NESHAP
may
apply.
See
§
63.5787
in
the
final
NESHAP
for
more
detail.

J.
Determination
of
Resin
and
Gel
Coat
HAP
Content
In
the
proposed
rule,
we
stated
that
facilities
could
determine
resin
and
gel
coat
HAP
content
using
material
safety
data
sheets
(
MSDS)
or
resin
specification
sheets.
In
the
final
rule,
we
have
included
§
63.5797,
which
describes
in
more
detail
how
to
determine
resin
and
gel
coat
HAP

content.
This
new
section
also
clarifies
that
only
organic
HAP
are
included
in
determining
HAP
content.
The
reason
is
that
we
have
no
data
to
indicate
that
any
other
HAP,
such
as
inorganic
HAP
potentially
present
in
pigments
or
resin
solids,
are
emitted
from
the
production
process.
We
also
now
include
a
provision
to
account
for
normal
manufacturing
tolerances
that
occur
in
resin
and
gel
coat
manufacture.

K.
New
Source
MACT
Floors
In
the
proposed
rule,
the
MACT
floor
for
all
open
molding
and
pultrusion
operations
located
at
new
sources
above
a
100
tpy
HAP
emission
threshold
was
a
95
percent
weight
reduction
in
HAP
emissions.
In
the
final
rule,
we
have
subcategorized
open
molding
and
pultrusion
operations
by
part
size.
For
open
molding
and
pultrusion
operations
that
produce
large
parts
the
floor
level
of
control
is
now
the
same
as
for
existing
sources.
Large
parts
are
defined
in
§
63.5805
(
d)(
2).
All
other
new
source
MACT
floors
are
unchanged.

V.
Summary
of
Responses
to
Major
Comments
This
section
presents
a
summary
of
significant
public
comments
and
responses.
A
summary
of
all
the
public
comments
that
were
received
and
our
responses
to
those
comments
can
be
found
in
Docket
ID
No.
OAR
 
2003
 
0003
(
formerly
Docket

Comment:
We
received
numerous
comments
on
the
above­
the­
floor
requirements
for
existing
sources.
First,
commenters
stated
that
EPA
had
significantly
underestimated
the
costs
of
add­
on
controls.
They
stated
that
industry
estimates
were,
in
some
cases,
ten
times
higher
than
our
estimates.
They
stated
that
we
had
overestimated
the
HAP
concentrations
in
the
exhaust
streams,
underestimated
the
exhaust
flows,
and
omitted
costs
for
continuous
monitors.
Second,
the
commenters
claimed
that
we
had
not
established
that
95
percent
capture
and
control
was
technically
feasible
for
this
diverse
industry,
and
that
only
two
facilities
out
of
433
actually
had
achieved
the
100
percent
capture
that
is
required
to
meet
an
overall
capture
and
control
level
of
95
percent.
They
also
stated
that
these
two
facilities
were
atypical
of
the
industry
as
a
whole
because
they
also
had
collocated
coating
operations
that
were
also
routed
to
the
same
control
device.
They
further
stated
that
the
criteria
of
EPA
Method
204
of
appendix
M
of
40
CFR
part
51
are
not
feasible
for
most
facilities
in
this
industry.
For
these
reasons,
the
commenters
recommended
that
the
above­
the­
floor
requirement
be
removed.
Response:
As
a
result
of
these
comments,
we
reviewed
the
costing
methodology
for
the
above­
the­
floor
requirements
in
the
proposed
rule
and
made
changes
to
our
costing
methodology
for
add­
on
controls.
Some
of
the
major
changes
were
lowering
the
default
inlet
concentration
to
the
control
device
from
100
parts
per
million
volume
(
ppmv)
to
50
ppmv,
revising
the
fan
power
equation,
and
using
2,000
operating
hours
per
year,
rather
than
6,000
hours
per
year,
as
a
default
value
in
the
absence
of
actual
yearly
operating
information.
Based
on
these
new
costs,
the
cost
per
ton
of
HAP
emissions
reduction
of
the
above­
the­
floor
requirement
significantly
increased
for
most
process/
product
groupings.
As
a
result,
we
have
removed
the
above­
the­
floor
control
requirements
for
all
process/
product
groupings
except
centrifugal
casting
and
continuous
lamination/
casting.
It
should
be
noted
that
the
comments
discussed
above
were
based
on
open
molding
operations.
We
received
no
comments
specifically
on
the
above­
thefloor
requirements
as
applied
to
centrifugal
casting
and
continuous
lamination/
casting.
Comment:
One
commenter
opposed
allowing
control
requirements
for
new
sources
emitting
less
than
100
tpy
to
be
the
same
as
those
for
existing
sources
because
a
new
site
has
the
opportunity
to
design
and
incorporate
pollution
prevention
and
control
strategies
that
would
be
cost­
prohibitive
for
existing
sources
to
implement.
The
commenter
recommended
that
EPA
consider
more
stringent
requirements
for
new
sources,
including
smaller
sources,
through
generally
available
control
technology
or
other
approaches
that
would
not
be
overly
burdensome.
Another
commenter
adds
that
EPA's
analysis
indicates
that
the
best
controlled
facilities
have
reduced
HAP
by
only
95
percent,
and
95
percent
is
most
likely
the
maximum
extent
of
historic
regulatory
requirements.
The
commenter
notes
that
EPA
looked
at
the
experience
of
existing
facilities
to
achieve
greater
than
95
percent
control
through
add­
on
control
in
conjunction
with
pollution
prevention
and
did
not
find
facilities
achieving
greater
control
than
that.
While
the
assessment
may
be
correct
for
what
EPA
looked
at,
the
commenter
states
that
examining
past
experience
that
lacks
regulatory
drivers
for
greater
control
is
not
the
same
as
examining
the
present
and
future
potential
for
control
opportunities.
The
commenter
believes
that
the
proposal
dismisses
the
potential
for
these
two
control
techniques
(
add­
on
control
and
pollution
prevention)
to
be
applied
to
new
sources.
Response:
We
agree
that
new
facilities
can
more
easily
incorporate
pollution
prevention
and
add­
on
controls.
This
is
the
reason
we
set
the
new
source
floor
at
95
percent
control
for
most
new
sources
that
emit
over
100
tpy,
and
not
at
the
same
level
as
existing
source
floors.
Facilities
that
have
incorporated
addon
controls
tend
to
be
larger
facilities.
New
facilities
in
this
industry
can
be
small
operations
that
operate
a
limited
number
of
hours
and
still
be
major
sources.
These
small
sources
cannot
reliably
meet
95
percent
capture
and
control
given
their
limited
operating
schedules
and
their
potential
lack
of
onsite
technical
expertise.
Therefore,
we
are
not
requiring
a
source
emitting
less
than
100
tpy
to
meet
the
95
percent
capture
and
control
level.
We
examined
whether
or
not
we
could
specify
some
other
level
of
control
for
small
sources,
but
we
could
not
determine
what
would
be
an
appropriate
level
of
capture
and
control
below
95
percent.
We
also
considered
basing
new
source
MACT
floors
for
facilities
that
emit
less
then
100
tpy
on
the
single
best
facility
that
incorporated
pollution
prevention.
However,
as
discussed
in
the
preamble
of
the
proposed
rule,
we
believed
that
using
one
facility
that
had
the
lowest
HAP
content
resins
and
gel
coats
was
unworkable,
unless
we
could
show
that
all
new
plants
would
build
the
same
products
as
the
plants
that
had
the
lowest
HAP
content
resins
and
gel
coats.
Given
this,
we
had
to
determine
a
threshold
value
above
which
95
percent
capture
and
control
is
feasible
for
all
new
plants,
given
the
diversity
of
this
industry.
We
selected
100
tpy
of
actual
HAP
emissions
because
above
this
level
facilities
tend
to
operate
more
hours
per
year
and
are
better
equipped
to
maintain
capture
and
control
systems.
Also,
at
the
time
we
proposed
the
rule,
the
smallest
facility
in
the
open
molding
process/
product
grouping
that
was
permitted
at
95
percent
capture
and
control
emitted
approximately
100
tpy.
Therefore,
we
chose
this
number
as
the
threshold
at
which
95
percent
capture
and
control
is
required.
This
was
not
the
only
approach
we
could
have
taken
to
subcategorize
new
sources,
nor
is
100
tpy
the
only
threshold
we
could
have
chosen.
For
example,
we
could
have
subcategorized
by
annual
hours
of
operation.
However,
depending
on
the
threshold
we
set,
this
could
result
in
large,
new
HAP
emissions
sources
avoiding
the
95
percent
capture
and
control

requirements
simply
by
building
a
larger
facility
and
reducing
hours
of
operation.
By
tying
the
requirement
directly
to
HAP
emissions,
we
believe
we
have
taken
the
most
logical
approach
from
an
environmental
standpoint
and
an
enforcement
standpoint.
Also,
the
100
tpy
threshold
is
a
reasonable
choice
that
means
that
all
new
large
facilities
in
most
of

to
meet
the
most
stringent
HAP

levels.
Comment:
We
received
numerous
comments
on
the
new
source
MACT
floor
for
facilities
with
open
molding,
pultrusion,
SMC
manufacturing,
mixing,
and
BMC
manufacturing
that
emit
100
tpy
or
more
of
HAP
from
these
operations.
The
commenters
stated
that
the
95
percent
capture
and
control
requirements
of
the
floor
were
technically
infeasible
and
too
costly.
They
also
stated
that
95
percent
capture
and
control
does
not
represent
the
best
HAP
emissions
control
approach
when
all
environmental
impacts,
such
as
increases
in
emissions
of
criteria
pollutant
and
greenhouse
gases,
are
considered.
The
commenters
note
that
the
CAA
states
that
the
best
controlled
similar
source
must
be
the
basis
of
the
new
source
MACT
floor;
therefore,
EPA
is
only
authorized
to
apply
the
95
percent
capture
and
control
requirements
to
facilities
that
are
similar.
The
sources
cited
by
EPA
make
uniformly­
sized
parts
in
high
volume,
employ
mechanical
resin
application,
and
operate
three
shifts
a
day.
However,
they
differ
from
other
facilities
in
the
industry.
One
of
the
sources
is
primarily
a
metal
fabrication
operation
and
sends
significant
amounts
of
emissions
from
a
painting
operation
to
the
control
device,
making
an
unusually
rich
combustion
stream.
They
also
claimed
that
the
facility
had
not
been
proven
to
meet
the
requirements
of
EPA
Method
204
of
appendix

The
other
facility
employs
an
unusual
molding
operation,
and
the
ability
of
this
facility
to
actually
meet
the
95
percent
capture
and
control
requirement
is
open
to
question.
Neither
of
these
sources
are
similar
to
any
other
composites
open
molding
operation.
Response:
Our
available
information
continues
to
support
that
the
appropriate
new
source
floor
for
facilities
that
emit
100
tpy
or
more
of
combined
HAP
from
their
open
molding,
pultrusion,
SMC
manufacturing,
BMC
manufacturing,
mixing,
centrifugal
casting,
continuous
lamination,
and
continuous
casting
operations
is
95
percent
capture
and
control
for
several
reasons.
First,
the
term
``
best
control''
means
best
control
of
HAP
emissions.
The
only
other
control
techniques
mentioned
by
the
commenters
were
the
pollutionprevention
techniques
that
make
up
the
existing
source
floors.
The
commenters
claim
that
when
other
environmental
impacts
of
add­
on
controls
are
considered,
pollution­
prevention
control
techniques
are
actually
superior.
They
provided
examples
that
showed
HAP
emissions
reductions
from
pollution­
prevention
techniques
for
some
facilities
of
up
to
approximately
70
percent;
however,
the
actual
HAP
emissions
reductions
a
facility
will
achieve
based
on
pollution­
prevention
techniques
will
be
highly
site
specific.
Also,
the
highest
pollution­
prevention
HAP
emissions
reduction
examples
assume
facilities
could
reduce
HAP
emissions
by
enhanced
process
monitoring,
which
would
reduce
materials
used.
The
HAP
emissions
reductions
based
on
materials­
use
reductions
assumes
facilities
are
not
currently
using
materials
as
efficiently
as
they
could.
There
are
no
data
to
support
this
assumption,
and
the
potential
for
HAP
emissions
reduction
of
this
type
could
vary
widely.
The
second
example
presented
by
one
commenter
assumes
facilities
would
use
nonatomized
gel
coat
application.
However,
the
same
commenter
has
stated
emphatically
that
nonatomized
gel
coat
application
cannot
be
used
at
every
facility.
Therefore,
this
example
cannot
be
considered
to
fairly
represent
the
HAP
emissions
reductions
achievable
for
the
industry
as
a
whole.
Our
overall
estimate
of
the
HAP
emissions
reduction
that
would
occur
with
only
pollution­
prevention
techniques
is
approximately
41
percent
for
open
molding,
compared
to
the
significantly
higher
95
percent
HAP
emissions
reductions
possible
with
capture
and
control.
The
CAA
indicates
that
``
best
control''
in
the
context
of
setting
floors
is
the
control
that
achieves
the
best
HAP
emissions
reduction.
Based
on
this,
95
percent
capture
and
control
represents
best
control
for
this
industry.
Even
if
we
were
to
consider
other
environmental
impacts
of
capture
and
control,
95
percent
control
would
still
be
considered
best
control.
Calculations
provided
by
one
commenter
indicates
that
a
total
of
only
0.15
tons
of
criteria
pollutants
are
generated
per
ton
of
styrene
reduction;
however,
this
number
appears
to
be
based
on
one
of
the
three
actual
operating
facilities
using
add­
on
controls
shown
in
the
commenter's
example.
Data
from
another
facility
using
a
concentrator/
oxidizer
system
in
the
same
report
showed
criteria
pollutant
emissions
of
0.06
tons
per
ton
of
styrene
emissions
reduction.
Our
estimate
at
proposal
was
that,
on
average,
this
figure
is
closer
to
0.04
tons
of
criteria
pollutants
per
ton
of
HAP
emissions
reduction.
Regardless
of
which
number
is
used,
the
amount
of
HAP
emissions
reduction
is
significantly
higher
than
any
resulting
criteria
pollutant
emissions.
The
commenters
also
cite
greenhouse
gas
effects.
They
state
that
30
tons
of
greenhouse
gases
are
produced
for
every
ton
of
styrene
emissions
reduction.
We
reviewed
the
information
that
formed
the
basis
of
the
estimate
of
greenhouse
gas
estimates.
Based
on
our
analysis,
we
believe
that
the
estimate
of
30
tons
of
greenhouse
gases
are
produced
for
every
ton
of
styrene
emissions
reduction
is
an
overestimate
because
it
is
based
on
examples
where
the
HAP
emissions
reduction
varies
between
77
to
84
percent.
The
final
rule
will
require
95
percent
HAP
emissions
reduction.
Also,
we
believe
the
air
flows
used
in
the
examples
provided
by
the
commenter
are
higher
than
will
be
required
for
new
facilities.
Higher
air
flows
result
in
increased
use
of
natural
gas
and
higher
greenhouse
gas
emissions.
We
believe
a
more
accurate
number
would
be
approximately
20
tons
of
greenhouse
gases
produced
for
every
ton
of
styrene
emissions
reduction.
Second,
regardless
of
which
number
is
the
most
accurate,
any
contribution
of
the
final
rule
to
global
greenhouse
gas
emissions
is
insignificant.
The
total
greenhouse
gas
emissions
in
the
United
States
exceed
6
trillion
tons
from
fossil
fuel
combustion
alone.
However,
the
difference
between
emissions
of
styrene
from
a
facility
controlled
to
the
95
percent
level
and
one
controlled
using
only
pollution
prevention
is
significant
to
the
populations
living
near
an
affected
facility.
The
commenters
also
stated
that
the
facilities
that
formed
the
basis
of
the
new
source
floor
are
not
``
similar
sources.''
We
disagree
because
there
are
actually
three
sources
within
this
source
category
that
meet
the
criteria
to
set
a
95
percent
capture
and
control
floor.
The
commenters
point
out
that
three
is
a
small
number
compared
to
the
433
facilities
in
the
database
at
proposal.
However,
the
CAA
requires
the
new
source
floor
to
be
based
on
the
single
best
performing
similar
source.
Therefore,
only
one
source
is
sufficient
to
set
a
new
source
floor
as
long
as
we
determine
it
is
similar.
The
commenters
stated
that
the
source
setting
the
floors
operates
three
shifts
(
they
shut
down
on
weekends).
However,
we
subcategorized
new
sources
by
annual
HAP
emissions.
The
reason
was
that
larger
sources
are
more
likely
to
operate
more
than
one
shift.
Also,
since
this
floor
only

Rules
and
Regulations
to
new
sources,
the
facility
can
be
designed
to
meet
the
necessary
production
rate
with
three
shift
operation
if
the
operator
desires
to
minimize
control
device
startups
and
shutdowns.
The
commenters
stated
that
in
two
cases,
the
floor
facilities
have
collocated
surface
coating
operations.
Our
evaluation
of
these
facilities
was
based
only
on
the
reinforced
plastic
composites
portion
of
the
facility.
During
site
visits
to
these
facilities,
we
determined
that
these
facilities
were
required
to
apply
95
percent
capture
and
control
to
all
major
processes
due
to
State
regulations.
That
requirement
would
apply
regardless
of
whether
or
not
the
facility
had
collocated
surface
coating
operations.
Also,
the
presence
of
the
surface
coating
operations
does
not
result
in
a
more
concentrated
exhaust
stream
compared
to
facilities
without
surface
coating
operations.
Thus,
there
is
no
technical
basis
to
say
these
facilities
are
not
similar
based
on
the
presence
of
surface
coating
operations.
We
also
reviewed
the
commenters
claim
that
the
facilities
that
set
the
new
source
floor
do
not
actually
meet
the
requirements
of
EPA
Method
204
of
appendix
M
of
40
CFR
part
51.
Part
of
that
claim
was
based
on
the
fact
that
the
floor
facilities
had
doors
in
the
PTE
that
were
opened
to
move
parts
and
materials
in
and
out
of
the
PTE.
One
criteria
of
EPA
Method
204
of
appendix
M
of
40
CFR
part
51
is
as
follows:
``
All
access
doors
and
windows
that
are
not
treated
as
natural
draft
openings
shall
be
closed
during
routine
operation
of
the
process''.
This
criteria
is
not
intended
to
require
that
these
doors
be
closed
at
all
times.
It
means
that
doors
must
be
closed
any
time
that
you
are
not
actually
moving
parts
or
equipment
through
them.
Therefore,
the
fact
that
the
floor
facilities
open
doors
to
move
parts
in
and
out
of
the
PTE
does
not
mean
they
do
not
meet
the
requirements
of
EPA
Method
204.
In
addition,
we
reviewed
the
compliance
determinations
for
two
of
the
floor
facilities.
Our
review
did
not
reveal
any
conditions
that
would
indicate
that
the
requirements
of
EPA
Method
204
of
appendix
M
of
40
CFR
part
51
are
not
being
met.
Comment:
The
commenters
stated
that
the
facilities
that
manufacture
large
parts
using
open
molding
or
pultrusion
are
not
similar
to
the
floor
facilities
that
are
the
basis
of
the
capture
and
control
requirements
for
the
new
source
floors.
They
stated
that
the
facilities
used
to
set
the
95
percent
capture
and
control
requirement
only
manufacture
small
parts
and,
therefore,
should
not
be
used
to
set
a
capture
and
control
floor
requirement
for
facilities
making
large
parts.
They
also
stated
that
achieving
100
percent
capture
is
not
feasible
for
large
parts
sources
in
these
process
groups.
Though
EPA
had
cited
facilities
that
coated
large
parts
in
permanent
total
enclosures
(
PTE),
coating
operations
cannot
be
considered
similar
to
the
manufacture
of
reinforced
plastic
composites.
They
suggested
that
any
part
with
any
dimension
that
exceeds
12
feet
be
considered
a
large
part
and
be
exempt
from
capture
and
control
requirements.
Response:
After
reviewing
the
comments
and
available
data,
we
have
determined
that
the
facilities
currently
achieving
95
percent
capture
and
control
are
not
similar
to
sources
producing
large
parts.
At
proposal,
we
noted
that
we
had
not
identified
any
facilities
in
the
reinforced
plastic
composites
industry
where
processes
producing
large
parts,
such
as
storage
tanks
and
swimming
pools,
have
applied
100
percent
efficient
capture
systems,
but
stated
our
belief
that
such
PTE
were
technically
feasible
based
on
large
PTE
in
other
industries.
We
reviewed
available
data
on
the
facilities
in
our
database
and
found
that
facilities
producing
parts
over
a
certain
size
presented
different
technical
issues
from
facilities
that
have
successfully
incorporated
95
percent
capture
and
control.
As
noted
in
the
preamble
to
the
proposed
rule,
one
of
these
facilities
has
a
PTE
large
enough
to
produce
large
parts.
However,
the
air
flows
and
HAP
concentrations
exiting
the
PTE
at
this
facility
are
not
the
same
as
would
be
expected
from
a
facility
using
a
similar
sized
PTE
to
capture
and
control
emissions
from
large
parts
production.
We
also
noted
in
the
preamble
to
the
proposed
rule
that
surface
coating
operations
for
very
large
parts
(
as
large
as
ocean
going
ships)
had
successfully
applied
PTE.
However,
we
agree
that
coating
operations
and
reinforced
plastic
composites
operations
are
not
similar
sources.
Reinforced
plastic
composites
production
typically
requires
more
workers
per
part
due
to
the
necessity
to
both
apply
and
roll­
out
the
resin.
Also,
large
parts
are
continuously
laminated
until
completion
rather
than
coated
in
sections.
This
difference
in
sources,
while
applicable
to
evaluating
floors
based
on
capture
and
control,
does
not
exist
in
the
case
of
floors
based
on
pollutionprevention
technologies
such
as
the
use
of
low­
HAP
materials
and
nonatomized
resin
application.
For
that
reason,
we
did
not
differentiate
between
large
and
small
parts
when
setting
floors
based
on
pollution­
prevention
control
techniques
for
either
new
or
existing
sources.
Because
we
determined
that
capture
and
control
was
not
the
appropriate
floor
for
large
parts
manufacture,
the
floors
for
these
specific
operations
are
now
the
same
as
the
floors
for
existing
operation,
which
are
emission
limits
based
on
the
use
of
low­
HAP
materials
and
nonatomized
resin
application.
However,
we
do
not
agree
with
the
commenter's
suggested
definition
of
large
parts,
because
it
would
exempt
parts
from
capture
and
control
requirements
where
those
requirements
have
already
been
demonstrated.
The
largest
part
produced
at
a
facility
where
95
percent
capture
and
control
is
demonstrated
has
a
volume
of
250
cubic
feet.
If
this
part
were
placed
in
a
rectangular
six­
sided
box,
the
largest
side
of
the
box
would
be
50
square
feet.
Therefore
we
chose
these
criteria
as
the
definition
of
a
large
part
for
open
molding.
For
pultrusion,
the
largest
part
produced
by
a
facility
with
95
percent
capture
and
control
was
2
inches
high,
10
inches
wide,
and
had
approximately
350
reinforcements.
Therefore,
we
choose
these
criteria
as
the
definition
for
large
pultruded
parts.
Comment:
Several
commenters
stated
that
capture
and
control
requirements
would
make
it
difficult
for
facilities
to
meet
Occupational
Safety
and
Health
Administration
(
OSHA)
worker
health
and
safety
requirements.
Process
enclosures
at
current
facilities
are
designed
and
operated
to
provide
safe
and
efficient
production
of
composite
products.
The
primary
purpose
of
enclosures
in
this
industry
is
to
remove
contaminated
air
from
the
workplace
to
achieve
OSHA
requirements
for
limiting
occupational
exposures.
Enclosures
must
also
allow
enough
cool
air
to
enter
the
workplace
so
that
workers
are
not
subject
to
excessive
heat
stress.
One
commenter
provided
a
study
that
stated
that
if
process
enclosure
exhaust
flows
were
reduced
to
increase
exhaust
concentrations
being
routed
to
the
control
device,
worker
exposure
to
contaminants
and
heat
would
be
increased
to
unacceptable
levels.
Response:
The
use
of
PTE
for
capture
of
HAP
emissions
should
not
result
in
increased
worker
exposure
to
contaminants
or
heat
stress
if
appropriate
precautions
are
taken.
As
previously
noted,
one
solution
is
to
design
the
spray
enclosures
based
on
meeting
worker
exposure
requirements,
and
then
enclosing
the
entire
lamination
area
in
a
PTE.
The
facilities
currently
using
PTE
do
not
exceed
OSHA
exposure
guidelines.
Experience
in
the
printing
and
publishing
industry
shows
that
use
of
PTE,
in
many
cases,

Comment:
Five
commenters
stated
that
the
limit
of
tooling
gel
coats
(
38
percent
HAP)
is
not
achievable.
One
commenter
claimed
that
we
set
this
limit
based
on
one
infrequently
used
product
that
is
not
representative
of
the
industry
as
a
whole.
The
commenter's
products
represent
70
percent
of
the
tooling
gel
coat
market
and
the
maximum
HAP
contents
range
from
42
to
50
percent
HAP.
Their
lower
HAP
gel
coat
has
not
gained
a
significant
market
acceptance.
They
have
performed
2
years
of
research
and
development
efforts
aimed
at
developing
a
lower­
HAP
gel
coat
that
would
meet
the
requirements
of
the
proposed
rule
and
have
been
unsuccessful.
They
stated
we
had
not
independently
tested
the
product
on
which
the
standard
is
based,
so
there
has
been
no
demonstration
of
the
product's
quality
or
suitability
for
broad
use
in
the
industry.
The
commenter
also
stated
that
setting
the
standard
at
38
percent
would
have
the
effect
of
encouraging
manufacturers
of
tooling
gel
coats
to
use
para
methyl
styrene,
which
is
not
regulated
as
a
HAP,
as
a
substitute.
Also,
lower­
HAP
gel
coats
may
be
less
durable
than
products
currently
on
the
market,
which
would
result
in
reduced
mold
life.
Therefore,
more
molds
would
have
to
be
built
to
produce
the
same
amount
of
product.
This
would
result
in
the
standard
actually
causing
a
HAP
emissions
increase.
This
commenter
requested
a
tooling
gel
coat
HAP
limit
of
52
percent
HAP
for
clear
gel
coats
and
49
percent
for
pigmented
gel
coats.
A
second
commenter
asked
that
EPA
consider
tooling
gel
coats
as
speciality
gel
coats
exempt
from
HAP
limits
similar
to
the
speciality
coating
exemption
contained
in
the
Aerospace
Coating
MACT
standards
(
40
CFR
part
63,
subpart
GG).
This
commenter
stated
there
is
a
strong
possibility
they
will
discontinue
manufacturing
tooling
gel
coats
if
the
standard
is
not
changed.
Another
commenter
stated
that
we
must
allow
higher
HAP
limits
for
tooling
applications
in
vacuum
resin
infusion,
compression,
and
resin
transfer
molding
composite
tool
applications,
where
high
exotherms
and
heated
tools
are
required.
Durability
of
the
mold
surface
is
essential
to
the
longevity
of
the
mold.
Thermal
stability
is
a
key
element
that
requires
higher­
HAP
content.
Repeated
high
exotherms
during
the
cure
cycles
can
greatly
reduce
the
life
of
low­
HAP
gel
coats.
Greater
porosity
found
in
the
low­
HAP
materials
can
also
create
mold
surface
problems.
Ironically,
these
are
closed
molding
processes,
which
result
in
much
lower
HAP
emissions
and
employee
exposures
than
open
molding
processes.
Closed
molding
facilities
will
not
be
able
to
offset
the
small
amounts
of
high­
HAP
tooling
gel
coat
used
in
tool
production
with
large
amounts
of
low­
HAP
general
purpose
open
molding
resins
using
facility
averaging.
The
commenter
recommends
that
the
final
MACT
standards
allow
up
to
48
percent
HAP
content
for
pigmented
tooling
gel
coats.
Response:
We
have
received
additional
data
since
proposal.
Based
on
these
data,
we
increased
the
floor
for
tooling
gel
coats
to
40
percent.
We
obtained
very
little
data
from
industry
on
tooling
gel
coats
in
the
original
data
requests
and
in
additional
efforts
to
obtain
additional
tooling
gel
coat
data.
To
supplement
the
limited
data,
we
looked
at
the
tooling
gel
coat
data
used
in
developing
the
Boat
Manufacturing
MACT
(
40
CFR
part
63,
subpart
VVVV).
This
is
a
reasonable
approach
because
gel
coat
manufacturers
stated
that
they
sold
the
same
tooling
gel
coats
in
both
the
reinforced
plastic
composites
and
boat
manufacturing
industries.
The
revised
HAP
content
limit
of
40
percent
is
the
same
as
the
Boat
Manufacturing
NESHAP
HAP
content
limit
for
tooling
gel
coats.
We
considered
the
issue
raised
by
the
commenters
that
a
low
limit
in
tooling
gel
coats
would
actually
increase
HAP
emissions.
While
we
agree
that
more
frequent
replacement
of
inferior
molds
would
lead
to
increased
HAP
emissions,
the
factual
data
do
not
indicate
that
a
40
percent
HAP
content
limit
results
in
inferior
molds.
Facilities
in
the
field
(
both
reinforced
plastic
composite
manufacturers
and
boat
manufacturers)
are
building
molds
with
40
percent
HAP
tooling
gel
coat.
We
have
no
data
to
indicate
that
these
facilities
are
producing
lower
quality
molds
than
average,
and
none
of
the
commenters
has
been
able
to
provide
objective
data
to
substantiate
that
reduced
mold
life
is
inevitable
with
low­
HAP
gel
coats.
The
information
provided
was
based
on
assumed
reduction
in
mold
life.
Also,
the
fact
that
one
of
the
commenters
covers
70
percent
of
the
market
is
irrelevant,
because
MACT
floors
are
set
based
on
best
control,
not
market
share.
In
the
absence
of
objective
data
that
the
facilities
that
use
low­
HAP
tooling
gel
coats
produce
inferior
molds
with
shorter
mold
lives
compared
to
the
rest
of
the
industry,
the
MACT
floor
must
be
set
based
on
the
best
performing
facilities.
In
this
case,
that
results
in
a
floor
of
40
percent
HAP.
Comment:
One
commenter
stated
that
although
clear
cultured
marble
gel
coats
have
been
formulated
with
HAP
levels
as
low
as
40
percent,
the
tolerance
for
thermal
shock
and
water
resistance
are
lowered
with
lower­
HAP
levels.
According
to
the
commenter,
48
percent
HAP
clear
coat
is
required
for
manufacturers
to
maintain
current
warranties
and
many
have
switched
back
to
the
high­
HAP
clear
gel
coats
due
to
the
poor
performance
of
the
lower­
HAP
clear
gel
coats.
The
commenter
suggests
that
``
clear
gel
coats
for
cultured
marble''
should
be
defined
as
``
those
used
for
products
subject
to
ANSI
Z124
testing''
and
the
rule
should
limit
the
HAP
content
of
these
materials
to
48
percent.
A
second
commenter
also
stated
that
a
48
percent
HAP
content
is
necessary
to
meet
desired
gel
coat
performance.
The
commenter
claims
that
the
proposed
limit
of
44
percent
does
not
take
into
account
the
entire
spectrum
of
uses
and
does
not
satisfy
the
requirements
of
their
applications.
Response:
We
are
bound
by
the
statutory
requirements
of
the
CAA
to
set
MACT
floors
based
on
the
average
of
the
best
performing
sources
as
illustrated
in
the
available
data.
In
the
absence
of
specific
data
to
support
the
request,
we
have
no
basis
to
change
the
floor.
In
developing
different
process
product
grouping
for
gel
coats,
we
did
consider
the
different
performance
characteristics
of
different
types
of
gel
coat.
These
types
were
tooling
gel
coat,
clear
gel
coat,
pigmented
gel
coat
(
white/
off
white),
pigmented
gel
coat
(
all
colors
except
white/
off
white),
fire
retardant
gel
coat,
and
corrosion
resistant/
high
strength
gel
coat.
Based
on
information
provided
by
industry,
we
determined
that
these
different
gel
coat
types
had
sufficiently
different
characteristics
that
they
should
be
considered
separately
for
floor
determinations.
However,
we
do
not
have
data
to
demonstrate
that
it
would
be
appropriate
to
further
subcategorize
clear
gel
coats
based
on
each
gel
coat's
performance
characteristics.
Comment:
One
commenter
states
that
only
the
white/
off­
white
and
some
pastels
can
meet
a
floor
of
30
percent
HAP
because
of
the
titanium
dioxide
and
inert
filler
loading.
Most
solid
colors
require
a
HAP
content
of
38
to
40
percent.
Higher
performance
pigmented
gel
coats
that
require
high
molecular
weights
would,
therefore,
need
a
higher
monomer
content
to
achieve
workable
viscosities
and
would
probably
no
longer
be
available
to
the
market
place.
Response:
White/
off­
white
gel
coats
will
be
defined
as

As
proposed,
these
gel
coats
will
be
subject
to
a
HAP
limit
of
30
percent
by
weight,
and
all
other
pigmented
gel
coats
will
be
subject
to
a
HAP
limit
of
37
percent
by
weight.
At
the
time
we
developed
the
proposed
rule,
we
had
no
data
on
pigmented
gel
coats
other
than
white/
off­
white
and
some
reds.
Based
on
industry
comments,
we
split
pigmented
gel
coat
into
two
groupings,
white/
offwhite
and
other
colors
due
to
the
fact
that
white/
off­
white
gel
coats
contain
titanium
dioxide,
which
is
a
heavy
pigment,
while
other
colors
do
not.
At
the
time
we
created
this
new
grouping,
we
requested
data
from
the
industry
concerning
the
HAP
contents
of
pigmented
gel
coats.
The
industry
representatives
indicated
that
these
gel
coats
typically
have
37
percent
HAP.
Because
non­
white
pigmented
gel
coats
comprise
a
very
small
part
of
the
total
industry,
we
elected
to
accept
the
37
percent
number
rather
than
attempt
to
gather
additional
data.
The
commenter
provided
no
data
to
support
their
request.
In
the
absence
of
new
data,
we
have
no
basis
to
change
this
floor.
Comment:
Two
commenters
request
that
the
category
of
fire
retardant
gel
coats
be
exempt
from
HAP
limits.
Both
commenters
note
that
fire
retardant
gel
coats
are
used
in
manufacturing
transportation
parts,
building
products,
trains,
airplane
parts,
and
theaters.
One
commenter
stated
that
these
are
all
critical
areas
of
applications
and
require
various
Underwriter
Laboratory
(
UL),
American
Society
for
Testing
and
Materials
(
ASTM),
and
Fire
Rating
Certifications.
It
was
suggested
that
fire
retardant
gel
coats
be
defined
as
``
those
used
for
products
for
which
low­
flame/
low­
smoke
resin
is
used.''
Response:
We
have
added
a
process/
product
grouping
for
fire
retardant
gel
coats.
These
gel
coats
are
defined
as
gel
coats
used
in
low­
flame
spread/
lowsmoke
product
applications.
We
have
established
a
HAP
emissions
limit
of
854
lb/
ton
which
is
equivalent
to
gel
coats
with
a
maximum
HAP
content
of
60
percent
using
atomized
application.
Comment:
Four
commenters
stated
that
we
need
to
establish
a
separate
process/
product
grouping
for
corrosionresistant
gel
coats.
The
commenters
stated
that
gel
coats
used
in
specific
corrosion
protection
applications
must
meet
the
same
requirements
as
corrosion­
resistant
resin.
One
commenter
added
that
gel
coats
requiring
chemical
resistance
to
a
wide
range
of
chemicals
including
acids,
bases,
and
solvents
are
often
based
on
the
resins
similar
to
those
that
make
up
the
structural
part
of
the
composite
and
provide
the
necessary
corrosion
resistance.
For
this
reason,
the
commenters
believe
that
the
HAP
limitation
for
corrosion­
resistant
gel
coats
should
be
48
percent,
the
same
as
it
was
in
the
proposed
rule
for
lamination
resins
used
to
make
corrosion­
resistant
composites.
It
was
suggested
that
``
corrosion­
resistant
gel
coats''
be
defined
as
``
those
used
for
products
made
with
corrosion­
resistant
resin''
and
that
the
rule
limit
the
HAP
content
of
these
materials
to
48
percent.
Response:
We
agree
that
there
are
technical
limitations
for
corrosionresistant
applications
that
warrant
a
separate
limit
for
corrosion­
resistant
gel
coats,
similar
to
the
separate
limits
established
for
other
specialty
resins
and
coatings.
In
the
final
rule,
we
established
a
separate
HAP
content
limit
of
48
percent
for
corrosion­
resistant
gel
coats
and
defined
them
as
``
those
gel
coats
used
to
manufacture
products
made
from
corrosion­
resistant
resin.''
We
believe
48
percent
HAP
is
the
appropriate
number
because
the
highest
HAP
content
level
allowed
in
all
the
corrosion­
resistant
resin
process/
product
groupings
is
48
percent.
Comment:
Several
commenters
stated
that
we
need
an
additional
process/
product
grouping
for
low­
shrink
resins.
These
resins
have
special
shrinkage
control
properties
that
are
unique
and
cannot
be
obtained
in
any
other
way.
These
resins
were
not
identified
when
EPA
surveyed
the
industry.
One
commenter
stated
that
a
specialty
process
group
is
needed
for
high
molecular
weight,
low­
shrink
resins
used
in
wind
turbine
blade
manufacturing.
The
resin
currently
in
use
is
42
percent
HAP
unfilled.
The
facility
would
be
unable
to
gain
any
relief
by
facility
averaging
because
the
facility
predominantly
uses
zero­
HAP
epoxy
resin,
rather
than
a
low­
HAP
production
resin.
Commenters
requested
that
EPA
create
a
subcategory
for
these
resins
with
a
maximum
HAP
level
of
48
to
52
percent.
Response:
Our
understanding
is
that
these
low­
shrink
resins
are
highly
filled
resins
with
special
chemistry
that
allows
them
to
cure
at
room
temperature
with
significantly
less
shrinkage
than
a
typical
resin.
Given
the
unique
properties
of
this
resin,
we
agree
that
a
separate
process/
product
grouping
is
appropriate.
The
resin
manufacturer
indicated
that
the
maximum
HAP
content
of
the
resin
is
50
percent.
Therefore,
we
have
set
HAP
emissions
limits
for
shrinkage­
controlled
resins
that
allow
up
to
50
percent
HAP.
This
specialty
resin
costs
significantly
more
than
other
resins,
which
provides
a
deterrent
for
facilities
using
the
resin
where
its
special
properties
are
not
necessary.
Comment:
One
commenter
believes
higher
HAP
limits
are
needed
for
the
filament
application
of
corrosionresistant
products.
The
commenter
claims
that
the
rule,
as
proposed,
will
eliminate
use
of
certain
types
of
corrosion­
resistant
resins
that
impart
required
properties
to
certain
applications.
The
commenter
noted
that
the
proposed
limit
for
corrosionresistant
filament
application
resins
was
lower
than
for
noncorrosion­
resistant
filament
application
resins.
The
commenter
believes
that
the
HAP
emissions
limit
for
all
categories
of
filament
application
should
be
178
lb/
ton,
and
stated
that
this
change
will
have
insignificant
impact
on
EPA's
total
HAP
emissions
reductions
target,
with
the
difference
in
HAP
emissions
reductions
being
3
tpy.
Another
commenter
states
that
the
proposed
MACT
of
42
percent
HAP
cannot
be
met
with
an
isophthalic
resin
without
some
compromise
to
the
physical
properties
of
the
cured
resin.
The
commenter
requested
EPA
to
consider
the
48
percent
HAP
limit
found
in
South
Coast
Air
Quality
Management
District
(
SCAQMD)
Rule
1162.
Response:
While
we
acknowledge
the
commenters
concerns,
we
developed
the
floor
for
this
process/
product
grouping
in
the
same
manner
as
floors
for
other
process/
product
groupings
in
open
molding.
We
gathered
data
from
industry
and
ranked
the
performance
of
the
facilities
in
the
corrosion­
resistant
process
group
and
set
the
MACT
floor
based
on
the
average
of
the
best
12
percent,
as
required
by
law.
Though
we
are
not
changing
the
floor
for
filament
application,
we
are
retaining
a
provision
included
in
the
proposed
rule
that
allows
facilities
to
use
the
same
resin
in
multiple
processes.
The
rationale
for
this
provision
is,
while
our
floor
development
ranking
procedure
is
correct,
we
also
realize
it
does
not
account
for
the
fact
that
some
facilities
use
multiple
operations
to
produce
components
of
the
final
product,
and
the
resins
used
in
the
subcomponents
must
be
compatible.
This
provision
will
allow
most
facilities
the
flexibility
to
use
the
necessary
level
of
HAP
in
corrosion­
resistant
applications
because
mechanical
operations
have
a
higher­
HAP
content
limit.
Comment:
One
commenter
recommended
that
the
model
point
value
for
corrosion­
resistant

application
be

to

in

resin
application.
The
commenter
notes
that
the
facility
that
sets
the
floor
using
a
40
percent
HAP
resin
is
not
typical
of
a
true
corrosion­
resistant
(
CR)
company
because
that
facility
uses
only
manual
application,
while
true
CR
companies
use
both
manual
and
mechanical
application
techniques.
A
second
commenter
requested
that
the
MACT
floor
for
manual
corrosion­
resistant
resin
be
changed
so
that
it
is
the
same
as
the
floor
for
mechanical
corrosionresistant
resin.
Response:
As
discussed
in
the
previous
response,
the
floor
is
based
on
the
data
available
for
this
process/
product
grouping.
However,
as
with
filament
application,
the
provision
allowing
facilities
to
use
the
same
resin
in
multiple
operations
should
allow
enough
flexibility
for
facilities
to
meet
rule
requirements,
but
still
produce
products
with
the
necessary
properties.
Therefore,
facilities
that
produce
corrosion­
resistant
and
noncorrosionresistant
products
using
both
manual
and
mechanical
resin
application
will
be
able
to
use
the
same
resin
in
both
operations.
Comment:
One
commenter
stated
that
the
proposed
MACT
of
35.5
percent
HAP
for
noncorrosion­
resistant
centrifugal
casting
would
result
in
a
resin
too
high
in
viscosity,
which
may
create
air
release
problems.
The
commenter
states
that
lower
molecular
weight
resins
would
cause
some
limitations
in
physical
property
requirements.
Response:
We
received
new
data
that
changed
the
floor
for
centrifugal
casting
to
37.5
percent
HAP.
With
less
than
30
facilities
in
the
process
group
for
which
we
have
data,
the
MACT
floor
must
represent
the
average
performance
of
the
top
five
facilities.
We
have
no
data
to
support
raising
the
floor
any
further.
Comment:
One
commenter
stated
that
they
believe
that
new
operations
should
be
subject
to
new
source
MACT
even
if
they
are
added
to
an
existing
source.
The
commenter
understands
that
there
are
cases
in
which
the
new
equipment
may
be
incorporated
within
an
existing
manufacturing
line,
making
it
difficult
to
employ
separate
controls
(
e.
g.,
if
all
the
equipment
is
controlled
at
a
later
end
point).
The
commenter
suggests,
however,
that
separate
and
more
specific
provisions
can
be
included
in
the
rule
to
govern
such
cases.
Response:
This
comment
is
only
applicable
to
new
source
MACT
for
specified
processes
that
emit
over
100
tpy,
because
below
that
level,
new
source
and
existing
source
MACT
are
the
same.
We
believe
that,
for
this
particular
industry,
the
ability
of
a
facility
to
incorporate
the
capture
and
control
requirements
of
new
source
MACT
for
larger
facilities
is
closely
related
to
the
structure
housing
the
process,
because
the
size
and
shape
of
the
existing
building
affects
the
layout
of
the
production
line.
Even
if
there
are
significant
process
changes,
this
by
itself
would
not
indicate
that
the
building
housing
the
process
has
been
changed,
thereby
making
retrofit
of
capture
and
control
systems
unfairly
difficult
compared
to
a
new
greenfield
facility.
We
believe
that
attempting
to
develop
a
detailed
set
of
requirements
that
could
cover
every
situation
would
be
unrealistic.
We
agree
that
this
provision
may
result
in
small
facilities
being
able
to
grow
significantly
without
becoming
new
sources.
However,
it
should
be
noted
that
in
the
final
rule,
we
have
overridden
the
portion
of
the
general
provisions
in
40
CFR
part
63
which
states
that
facilities
that
move
are
still
considered
existing.
Because
we
believe
the
cost
and
technical
feasibility
of
capture
and
control
are
closely
related
to
the
building
housing
the
process,
we
believe
that
a
facility
that
moves
should
be
considered
a
new
source
because
they
can
plan
for
capture
and
control
prior
to
erecting
or
selecting
a
new
building.
Therefore,
facilities
that
would
be
considered
existing
sources
under
the
general
provisions
will
be
considered
to
be
new
sources
under
the
final
rule.
Therefore,
in
this
aspect,
the
final
NESHAP
are
more
stringent.
Comment:
Several
commenters
requested
clarification
in
this
rule
on
which
operations
at
a
reinforced
plastics
composites
facility
and
which
operations
at
a
boat
building
facility
will
be
covered
by
this
rule
and
which
will
be
covered
by
40
CFR
part
63,
subpart
VVVV
(
Boat
Manufacturing
NESHAP).
It
was
noted
that
neither
the
preamble
nor
the
proposed
rule
explicitly
states
whether
this
rule
applies
to
manufacturing
of
boats
or
boat
components
and
requested
that
language
be
added
to
the
final
rule
clarifying
that
this
rule
does
not
apply
to
any
processes
or
operations
subject
to
40
CFR
part
63,
subpart
VVVV.
One
commenter
stated
that
boat
building
plants
routinely
produce
non­
boat
parts
and
presumed
that
such
facilities
will
be
required
to
meet
the
composites
rule
when
producing
composite
parts
that
are
not
associated
with
the
manufacture
of
boats.
The
commenter
also
points
out
that
some
composite
plants
produce
boat
parts
that
are
then
used
to
build
boats,
such
as
when
producing
barge
covers
that
are
related
to
the
manufacture
of
river
barges.
Response:
We
have
added
§
63.5787
to
the
final
rule
to
specifically
address
this
issue.
A
facility
must
produce
boat
hulls
and
decks,
or
molds
for
boat
hulls
and
decks,
to
be
covered
by
the
Boat
Manufacturing
NESHAP
(
40
CFR
part
63,
subpart
VVVV).
If
it
produces
reinforced
plastic
composites,
as
defined
in
the
final
rule,
and
is
not
covered
by
the
Boat
Manufacturing
NESHAP,
then
it
is
covered
by
the
Reinforced
Plastic
Composites
NESHAP,
regardless
of
the
final
use
of
the
parts.
In
the
case
where
a
facility
is
subject
to
the
Boat
Manufacturing
NESHAP
(
40
CFR
part
63,
subpart
VVVV),
but
the
facility
also
makes
parts
that
are
not
a
component
of
their
boats,
then
the
nonboat
parts
are
covered
by
the
Reinforced
Plastic
Composites
NESHAP.
However,
only
resins
and
gel
coats
actually
used
to
make
parts
covered
by
the
Reinforced
Plastic
Composites
NESHAP
are
considered
in
determining
compliance.
In
addition,
in
order
to
simplify
compliance,
we
are
allowing
facilities
that
are
subject
to
the
Boat
Manufacturing
NESHAP
(
40
CFR
part
63,
subpart
VVVV)
and
that
also
make
parts
subject
to
the
Reinforced
Plastic
Composites
NESHAP,
to
elect
to
make
all
their
manufacturing
operations
subject
to
the
Boat
Manufacturing
NESHAP
if
they
can
demonstrate,
through
the
appropriate
HAP
emissions
calculations,
that
this
will
not
result
in
any
HAP
emissions
increases
over
what
would
occur
if
they
complied
with
the
Reinforced
Plastic
Composites
NESHAP
for
non­
boat
part
production.
We
also
clarify
that
HAP
emissions
from
activities
covered
by
the
Boat
Manufacturing
NESHAP
are
not
considered
when
calculating
HAP
emissions
thresholds
to
determine
the
applicability
of
add­
on
controls.
Comment:
One
commenter
requested
that
the
rule
explain
what
happens
in
instances
where
the
100
tpy
threshold
is
exceeded
even
by
a
little,
temporarily.
Does
this
require
that
add­
on
controls
be
installed?
Response:
It
is
our
intent
that
unusual
circumstances
result
in
a
facility
having
to
add
and
operate
add­
on
controls.
We
have
included
clarifying
language
in
the
final
rule
that
allows
a
one­
time
exemption
to
the
95
percent
capture
and
control
requirements
for
facilities
that
were
below
the
100
tpy
threshold
and
exceed
the
threshold
due
to
unusual
circumstances.
This
exemption
allows
facilities
to
average
annual
HAP
emissions
over
3
years
to
determine
if
they
exceed
the
threshold.
However,
facilities
are
also
required
to
document
the
unusual
circumstances
that
caused
the
exceedance,
and
why
they
expect
to
remain
below
the
threshold

If
they

a

is

95

Comment:
Two
commenters
requested
clarification
of
several
issues
related
to
repair
work.
They
are
assuming
the
proposed
rule
is
intended
to
cover
manufacturing
operations
only.
Repair
processes
conducted
in
a
manufacturing
facility
are
also
covered
because
they
are
likely
to
use
the
same
materials.
If
the
processes
conducted
are
remanufacturing
refurbishment,
repair,
or
maintenance,
it
will
be
considered
repair
for
the
final
NESHAP.
The
exception
would
be
if
the
repair
is
a
part
which
frequently
needs
replacement
and
is
made
in
an
assembly­
line
type
process.
They
also
asked
that
since
there
is
no
de­
minimums
level,
if
any
manufacturing
is
done,
would
it
be
covered?
They
noted
that
at
some
of
the
commenter's
facilities,
some
minor
manufacturing
may
occur.
The
repair
work
that
may
also
be
done
at
the
same
facility
is
not
related
to
the
manufacturing
processes
(
and
would
be
using
different
resin
and
reinforcing
materials.)
The
commenter
believes
that
as
the
rule
is
currently
written,
both
the
manufacturing
and
repair
operations
would
be
covered.
The
commenter
does
not
believe
that
is
EPA's
intent
and
asked
if
we
could
develop
language
to
correct
that.
One
commenter
stated
that
definitions
of
repair
and
manufacturing
should
be
added
to
clarify
the
types
of
repair
and
manufacturing
covered
by
the
rule.
The
preamble
and
rule
should
be
consistent
in
stating
that
the
facilities
that
only
repair
composites
are
not
affected.
The
commenter
also
feels
that
repair
operations
collocated
with
unrelated
manufacturing
operations
should
not
be
covered
either.
In
a
related
comment,
several
commenters
asked
that
a
lowuse
cutoff
be
established
so
that
facilities
that
use
small
amounts
of
resin
and
gel
coat
are
not
subject
to
the
rule,
especially
since
those
uses
may
be
incidental
to
a
completely
different
manufacturing
operation.
Response:
The
final
rule
has
been
written
to
make
explicit
what
repair
operations
are
and
are
not
covered.
Specifically,
facilities
at
which
only
repair
occurs
are
not
covered
by
the
final
rule.
In
addition,
repair
of
previously
manufactured
reinforced
plastic
composites
unrelated
to
the
reinforced
plastic
composites
manufactured
at
the
facility
are
also
not
covered
by
the
final
rule.
Repair
processes
on
parts
that
are
manufactured
at
the
same
location
are
covered
by
the
final
rule.
In
addition,
we
have
added
a
low­
use
cutoff
exemption
to
the
final
rule.
We
reviewed
our
entire
database
and
determined
that
we
had
no
data
for
facilities
that
use
less
than
1.2
tpy
of
resin
and
gel
coat
combined.
Therefore,
we
believe
that,
in
the
absence
of
any
available
data,
facilities
that
use
less
than
1.2
tpy
of
resin
and
gel
coat
to
produce
reinforced
plastic
composite
products
or
components
should
be
exempt
from
the
final
rule.
Comment:
Many
commenters
requested
that
the
rule
incorporate
an
exemption
for
R&
D
facilities,
and
for
R&
D
operations
collocated
with
manufacturing
operations.
The
materials
used
in
R&
D
operation
may
be
significantly
different
from
those
used
in
manufacturing.
Response:
We
have
written
the
final
rule
to
exempt
R&
D
facilities
and
R&
D
operations.
The
definition
of
R&
D
is
the
same
as
contained
in
section
112(
c)(
7)
of
the
CAA.
Comment:
Several
commenters
stated
that
they
believe
the
EPA
cannot
set
different
standards
for
small
and
large
businesses
based
on
the
size
of
the
business,
rather
than
the
size
of
the
source.
They
believe
that
because
the
CAA
clearly
identifies
``
major
source''
by
the
level
of
HAP
emissions,
MACT
floors
must
depend
on
the
average
HAP
emissions
reductions
by
the
best
sources
without
regard
to
cost
factors
of
business
size.
They
stated
that
this
distinction
was
unfair
because
two
facilities
that
emit
the
same
amount
of
HAP
would
potentially
have
different
requirements
solely
on
the
basis
of
their
ownership.
The
commenter
also
believes
that
EPA
did
not
adequately
support
the
determination
that
large
businesses
have
better
access
to
capital
than
small
businesses.
They
stated
that
this
is
not
necessarily
true.
Response:
Based
on
the
revised
cost
analysis,
we
have
determined
that
it
is
no
longer
necessary
to
distinguish
between
small
and
large
businesses.
However,
we
still
believe
the
use
of
different
thresholds
in
the
proposed
rule
was
appropriate
because
this
distinction
only
applied
to
the
above­
the­
floor
regulatory
option.
The
CAA
specifically
states
that
when
we
go
above
the
floor,
we
must
consider
costs.
Comment:
One
commenter
states
that
the
small
business
threshold
of
250
tpy
should
apply
to
both
existing
and
new
sources.
New
capital
funding
to
build
a
new
facility
would
require
due
diligence
on
the
part
of
the
lending
institution.
The
new
facility
would
have
to
generate
enough
cash
flow
to
meet
the
added
debt
load.
Adding
a
capture
and
control
system
to
the
debt
load
would
significantly
reduce
the
cash
flow
available
to
pay
back
the
lender's
note
on
a
new
facility
because
the
capture
and
control
system
is
a
nonvalue
added
asset.
The
lending
institution
would
discern
this
and
deny
the
loan.
Response:
For
new
sources,
the
proposed
(
and
final
standard)
is
the
MACT
floor,
not
an
above­
the­
floor
option.
We
do
not
have
the
flexibility
to
create
small
and
large
business
distinctions
when
the
standard
is
set
at
the
MACT
floor.
Therefore,
the
final
rule
for
new
sources
does
not
incorporate
a
small
and
large
business
distinction.
Comment:
Several
commenters
stated
that
a
method
to
establish
percent
reduction
and
HAP
emissions
factors
is
needed
to
foster
the
development
of
new
products
and
equipment
to
serve
the
affected
industry.
They
recommended
that
EPA
establish
a
protocol
to
allow
the
smooth
introduction
of
equipment,
products,
and
other
technologies
into
the
final
rule.
Response:
Allowing
facilities
to
use
site­
specific
HAP
emissions
factors,
and
the
procedure
in
the
general
provisions
in
40
CFR
part
63,
subpart
A,
that
allows
facilities
to
demonstrate
equivalent
HAP
emissions
reductions,
adequately
address
the
incorporation
of
new
HAP
emissions
reduction
technologies.
However,
we
have
added
§
63.5798
to
the
final
rule
that
discusses
how
to
obtain
approval
for
new
technologies.
Comment:
Two
commenters
requested
that
EPA
change
the
averaging
provisions
to
allow
a
facility
that
changes
some
processes
to
non­
styrene
containing
resins
to
average
these
resins
with
the
styrene­
containing
resins
to
demonstrate
compliance.
Response:
We
do
not
believe
it
would
be
appropriate
to
allow
the
use
of
nonstyrene
containing
resins
and
gel
coats
to
be
included
in
the
calculation
of
compliance.
The
MACT
floors
were
developed
only
considering
resins
and
gel
coats
that
contain
styrene
(
and
other
organic
HAP,
such
as
MMA)
used
at
the
facilities
in
our
database.
We
did
not
consider
non­
styrene
resins
and
gel
coats
used
at
our
database
facilities.
Given
the
basis
for
developing
the
standards,
it
is
inconsistent
to
allow
non­
styrene
containing
resins
and
gel
coats
to
be
used
in
the
compliance
calculations.
Therefore,
we
have
not
added
this
request
to
the
final
rule.

table.
The
composites
industry
is
already
using
these
HAP
emissions
factors
to
calculate
annual
HAP
emissions.
It
would
simplify
reporting
and
recordkeeping
if
one
set
of
HAP
emissions
factor
equations
were
used.
Another
commenter
stated
that
if
EPA
uses
the
UEF,
all
HAP
should
be
treated
as
styrene
because
this
is
how
EPA
developed
the
MACT
floors.
They
noted
that
these
factors
are
used
by
industry
for
toxic
release
inventory
reporting
and
obtaining
permits.
According
to
the
commenters,
use
of
these
factors
for
MACT
will
reduce
the
paperwork
burden
for
small
manufacturers.
Response:
We
reviewed
the
UEF
and
the
basis
for
their
development.
Based
on
this
review,
we
believe
that
these
equations
are
acceptable
for
estimating
both
HAP
emissions
factors
for
compliance
purposes
and
HAP
emissions.
As
a
result,
in
the
final
rule
we
have
written
the
HAP
emissions
factor
equations
in
Table
1
to
subpart
WWWW
of
part
63
to
be
identical
to
their
equivalent
UEF
equations.
Therefore,
facilities
will
have
one
set
of
identical
factors
for
both
compliance
and
HAP
emissions
estimation
purposes.
Because
of
this
change,
it
was
necessary
to
recalculate
the
floor
values
by
recalculating
HAP
emissions
factors
using
the
new
HAP
emissions
factor
equations
for
the
facilities
in
our
database
and
reranking
the
facilities
based
on
the
new
calculations.
Therefore,
both
the
numerical
values
of
the
floors
(
lb/
ton)
and
the
equations
used
to
calculate
compliance
changed.
Note
the
floors
themselves
did
not
change
significantly
because
when
we
reranked
facilities
using
the
new
HAP
emissions
factors,
the
ranking
order
did
not
change
with
two
exceptions.
In
those
cases,
the
new
equations
caused
two
facilities
to
switch
places
and
changed
the
floor
slightly.
However,
these
changes
were
minor
compared
to
the
changes
that
resulted
from
other
comments
we
received
and
additional
data
we
gathered.
In
addition,
we
have
added
to
the
final
rule
equations
for
the
nonatomized
gel
coat
application
and
for
the
mechanical
atomized
controlled
spraying
of
resins.
We
have
incorporated
the
latter
UEF
equation
in
the
final
rule
so
that
it
is
applicable
only
where
the
controlled
spray
is
achieved
through
automated
or
robotic,
not
manual,
spraying.
Finally,
we
are
incorporating
only
the
UEF
equations
developed
for
styrene
and
not
those
developed
for
MMA.
We
are
doing
this
because
the
data
analysis
forming
the
basis
of
the
standards
assumed
all
organic
HAP
to
be
styrene.
This
is
a
reasonable
assumption
as
the
amount
of
MMA
used
is
a
very
small
percentage
of
the
total
HAP
monomer
used.
Comment:
One
commenter
noted
that
the
proposed
rule
does
not
provide
for
manual
application
of
gel
coats.
Many
gel
coats
are
applied
manually
as
exterior
coatings
when
the
major
component
part
is
made.
The
rule
should
require
that
for
HAP
emissions
calculations
from
manual
application,
gel
coat
should
be
considered
as
a
resin
with
the
stated
HAP
content
and
the
appropriate
point
value
equation
should
be
used.
Companies
where
manual
gel
coat
application
is
less
than
2
percent
of
the
total
gel
coat
usage
should
be
exempt
from
maintaining
records
of
manual
application.
Response:
We
agree
with
the
commenter
that
the
proposed
rule
did
not
provide
an
equation
to
estimate
HAP
emissions
from
the
manual
application
of
gel
coats
and
that
the
rule
needs
to
address
this.
In
the
final
rule,
we
have
addressed
this
issue
by
allowing
two
options.
First,
the
facility
may
elect
to
simply
include
manuallyapplied
gel
coat
with
spray
gel
coat
application
for
compliance
and
HAP
emissions
estimation
purposes.
Alternatively,
they
can
elect
to
treat
the
gel
coat
as
spray
for
compliance
purposes,
but
use
the
manual
resin
application
HAP
emissions
factor
to
estimate
HAP
emissions.
We
believe
the
changes
discussed
above
are
sufficient
to
simplify
reporting
and
recordkeeping
for
manual
gel
coat
application.
Therefore,
we
have
not
added
an
exemption
for
maintaining
records
for
manual
gel
coat
application.
Comment:
Several
commenters
requested
that
sources
be
allowed
to
use
HAP
emissions
factors
in
approved
title
V
permits
to
estimate
HAP
emissions.
It
was
noted
that
the
use
of
such
factors
will
reduce
the
administrative
burden
for
sources
and
regulators
and
will
likely
improve
HAP
emissions
estimates.
One
commenter
suggested
that
such
factors
also
be
allowed
to
be
used
for
compliance
determinations.
Response:
We
agree
with
this
comment
and
believe
that
§
63.5798(
a)(
1)
and
(
2)
of
the
final
rule
already
allow
for
the
use
of
facilityspecific
HAP
emissions
factors.
Section
63.5798(
a)(
1)
states,
in
part,
that
``
you
may
use
any
organic
HAP
emissions
factor
approved
by
us
such
as
factors
from
the
Compilation
of
Air
Pollutant
Emissions
Factors,
Volume
I:
Stationary
Point
and
Area
Sources
(
AP
 
42).''
Section
63.5798(
a)(
1)
was
not
intended
to
limit
organic
HAP
emissions
factors
only
to
the
AP
 
42.
Paragraph
(
a)(
2)
of
§
63.5789
allows
the
development
of
facility­
specific
organic
HAP
emissions
factors
through
performance
testing.
If
a
facility
has
facility­
specific
factors
that
have
been
approved
for
use
in
title
V
operating
permits,
then
those
factors
can
be
used
to
determine
whether
or
not
the
facility
is
a
major
source
under
section
112
of
the
CAA.
In
addition,
a
facility
can
use
facility­
specific
factors
for
comparison
against
applicable
HAP
emissions
limits.
We
have
written
the
language
in
§
63.5798
of
the
final
rule
to
clarify
the
use
of
such
facility­
specific
factors
and
have
added
the
provision
that
such
factors
must
be
supported
by
test
data.
Comment:
One
commenter
notes
that
the
alternative
point
values
in
Table
5
to
subpart
WWWW
of
part
63
do
not
provide
a
realistic
alternative
to
95
percent
capture
and
control.
In
an
example
calculation
for
35
percent
styrene
resin
in
open
molding,
the
point
value
calculation
is
equivalent
to
96
percent
control,
which
is
more
stringent
than
the
add­
on
control
requirement.
Response:
While
the
values
may
not
appear
realistic
for
some
facilities,
Table
5
to
subpart
WWWW
of
part
63
does
present
the
opportunity
to
meet
the
final
standards
using
alternative
means.
We
believe
that
the
values
in
Table
5
to
subpart
WWWW
of
part
63
provide
incentive
to
continue
to
pursue
lower­
HAP
resins
and
gel
coats
and
other
pollution­
prevention
opportunities
and
that
even
if
only
one
facility
can
use
the
values,
then
their
inclusion
is
worthwhile.
For
these
reasons,
we
have
retained
Table
5
to
subpart
WWWW
of
part
63.
However,
we
have
made
minor
modifications
to
this
table.
For
process/
product
groupings
where
there
is
an
operating
facility
that
currently
meets
the
95
percent
control
requirement,
we
changed
the
value
in
Table
5
to
subpart
WWWW
of
part
63
to
reflect
the
highest
actual
calculated
HAP
emissions
factors
for
operating
facilities.
Comment:
One
commenter
stated
that
the
weighted
average
point
values
should
be
calculated
as
a
weighted
average
of
resin
used.
The
commenter
pointed
out
that
the
equation
in
the
current
proposal
gives
equal
weight
to
each
month
instead
of
each
quantity
of
resin
or
gel
coat
processed.
Another
commenter
asked
for
clarification
on
how
the
``
weighted
average
floor''
is
calculated.
Response:
We
agree
with
the
commenter
that
12­
month
rolling
average
point
values
should
be
calculated
using
a
weighted
average
based
on
the
amount
of
resins,
rather
than
using
an
average
based
on
monthly
values,
as
was
proposed.
Therefore,
the
final
rule
incorporates
the
commenters'
suggestion.
Also,
we
have
changed

We
now
use
the
term
``

when
discussing
values
calculated
using
actual
resin
and
gel
coat
HAP
contents,
and
``

This

Comment:
Several
commenters
asked
that
EPA
include
a
test
method
to
determine
the
effectiveness
of
vapor
suppressants.
They
suggested
that
the
CFA­
developed
vapor
suppressant
test
method
be
used.
Response:
We
agree
with
the
commenter
that
the
final
rule
should
incorporate
a
test
method
applicable
to
vapor
suppressants,
which
are
effective
at
reducing
HAP
emissions
for
many
resin
applications.
The
effectiveness
of
vapor
suppressants
varies
depending
on
the
resin
and
the
application
technique
used.
Thus,
a
single
effectiveness
value
cannot
be
assigned.
The
final
rule,
therefore,
incorporates
a
test
method
to
determine
the
effectiveness
of
vapor
suppressants
for
facility­
specific
applications.
This
test
method
is
being
published
as
appendix
A
to
subpart
WWWW
of
40
CFR
part
63.
Comment:
One
commenter
states
that
the
proposed
rule
is
vague
or
silent
on
key
issues
including
continuous
monitoring
of
the
preconcentrator
control
performance.
The
commenter
states
that
the
question
of
the
practical
long­
term
efficiency
of
the
preconcentrator
system
is
particularly
disturbing
because
the
proposed
rule
is
silent
on
the
issue
of
compliance
assurance.
Unfortunately,
compliance
assurance
will
present
three
problems:
no
available
parametric
measure
will
work
to
monitor
absorber
efficiency;
continuous
or
semi­
continuous
flame
ionization
detectors
(
FID)
are
the
only
practical
alternative,
but
are
unreliable;
and
automated
FID
equipment
is
very
expensive
and
prone
to
periods
of
malfunction.
The
commenter
also
states
that
the
only
feasible
available
continuous
emissions
monitor
(
CEM)
system
that
can
measure
styrene
is
an
automated
sampling
device
based
on
an
equivalent
FID
sensor
as
described
in
EPA
Method
25A
of
appendix
A
 
7
to
40
CFR
part
60
that
has
an
annual
cost
of
$
78,200
per
year.
The
additional
cost
of
this
necessary
compliance
monitoring
equipment
was
not
included
in
the
EPA
cost
analysis.
Response:
We
have
reviewed
the
information
on
those
facilities
using
add­
on
control
devices
with
carbon
adsorbers
within
the
reinforced
plastic
composites
industry
and
have
found
none
that
are
using
FID.
These
facilities
are
able
to
demonstrate
compliance
with
95
percent
reduction.
Therefore,
we
do
not
believe
it
is
necessary
to
require
use
of
FID
under
the
final
rule
and
have
not
included
the
cost
of
such
devices
in
our
cost
analysis.
Comment:
One
commenter
notes
that
the
requirements
for
sources
to
determine
the
HAP
content
should
be
the
same
as
those
in
the
Boat
Manufacturing
NESHAP
(
40
CFR
part
63,
subpart
VVVV).
The
commenter
points
out
that
the
boat
rule
allows
sources
to
use
information
from
the
supplier
or
manufacturer
and
requires
the
use
of
the
upper
limit
of
a
range
if
a
range
is
provided
and
allows
use
of
supplier
information
as
long
as
a
measured
value
does
not
exceed
the
provided
value
by
more
than
2
percentage
points.
The
commenter
notes
that
suppliers
provide
many
of
the
same
resins
and
gel
coats
to
boat
manufacturers
and
composites
manufacturers.
Response:
We
agree
with
the
commenter
and
the
final
rule
has
been
written
in
line
with
the
HAP
content
determination
provisions
found
in
the
Boat
Manufacturing
NESHAP,
which
in
part
allow
up
to
a
plus
or
minus
2
percent
allowance.
Comment:
One
commenter
stated
that
the
rule
should
allow
composites
manufacturers
to
change
compliance
options
and
should
provide
guidance
on
notification
and
record
keeping
requirements
if
affected
sources
need
to
switch
compliance
options.
Response:
We
agree
with
the
commenter
and
have
included
language
in
the
final
rule
making
it
clear
that
changes
in
the
selected
compliance
option
are
allowed.
Comment:
One
commenter
opposed
capture
and
control
for
pultrusion
sources
based
on
worker
safety.
The
commenter
notes
that
the
EPA
analysis
assumes
an
inlet
concentration
of
100
ppmv,
but
their
measured
concentrations
are
about
12
ppmv.
At
that
concentration,
according
to
the
commenter,
capture
and
control
is
not
viable.
The
commenter
claims
that
efforts
to
increase
the
inlet
concentration
lead
to
OSHA
and
industrial
hygiene
concerns
and
that
any
changes
increasing
the
concentration
to
over
20
ppmv
would
exceed
American
Congress
of
Governmental
Industrial
Hygienists
recommended
maximums.
Further,
the
commenter
states
that
levels
approaching
50
ppmv
require
installation
of
engineering
controls
(
ventilation
or
HAP
prevention)
and
exposure
to
these
levels
would
meet
with
serious
union
objections.
The
commenter
notes
that
these
considerations
result
in
higher
capture
and
control
costs.
The
commenter
requests
that
health
related
issues
be
fully
addressed
before
the
proposed
above­
the­
floor
capture
and
control
is
implemented.
Another
commenter
stated
that
pultrusion
products
requiring
constant
attention
would
have
to
have
an
enclosure
large
enough
for
the
operator
to
be
inside,
and
this
would
increase
health
risks
due
to
styrene
exposures.
Response:
As
noted
in
previous
responses,
the
above­
the­
floor
requirement
for
95
percent
HAP
emissions
reduction
is
no
longer
required
for
pultrusion
operations
at
existing
sources
and,
therefore,
capture
and
control
is
no
longer
an
issue
for
existing
facilities.
We
also
note
that
our
revised
cost
analysis
now
uses
a
target
maximum
inlet
concentration
of
50
ppmv
rather
than
100
ppmv.
The
50
ppmv
target
is
the
same
as
the
current
OSHA
8­
hour
time
weighted
average
limit
for
styrene.
We
have
not
changed
our
position
on
capture
and
control
for
new
sources,
except,
as
discussed
above,
with
respect
to
large
parts
made
by
pultrusion
(
and
open
molding)
sources.
New
facilities
can
be
designed
with
the
appropriate
measures
in
place
to
avoid
worker
exposure
in
excess
of
OSHA
requirements.
As
previously
discussed,
facilities
that
have
incorporated
capture
and
control
meet
current
OSHA
requirements
for
worker
safety.
Comment:
Several
commenters
requested
that
preform
injection,
a
technique
that
applies
resin
to
the
reinforcements
in
a
closed
box,
be
an
allowed
control
technology
because
it
is
a
more
viable
and
readily
attainable
control
technology
than
either
add­
on
control
or
direct­
die
injection.
One
commenter
stated
that
preform
injection
should
qualify
for
a
90
percent
HAP
emissions
reduction,
and
the
CFA
proposed
definition
and
requirements
should
be
used
as
the
criteria
for
preform
injection.
A
second
commenter
stated
that
although
it
falls
short
of
95
percent
reduction,
reduction
rates
of
90
percent
are
attainable
and
an
excellent
trade
off
given
the
applicability,
capital
requirements,
and
operating
costs
associated
with
preform
injection.
Response:
We
agree
with
the
commenters
that
preform
injection
is
a
viable
control
technology
for
reducing
HAP
emissions
from
pultrusion
operations.
Preform
injection
is
included
in
the
final
rule
as
an
option
for
meeting
the
60
percent
HAP
emissions
reduction
requirement
for
existing
pultrusion
sources.
However,

stated
by
the
commenters,

Rules
and
Regulations
not
meet
the
95
percent
HAP
emissions
reduction
requirement,
which
is
the
new
source
MACT
floor.
The
CAA
does
not
allow
us
to
be
less
stringent
than
the
floor.
Therefore,
we
cannot
allow
preform
injection,
or
direct
die
injection,
to
be
a
compliance
option
to
meet
the
95
percent
HAP
emissions
reduction
requirement.
We
also
included
a
definition
for
preform
injection
in
the
final
rule
that
is
based
on
the
commenter's
suggested
language.
Comment:
Several
commenters
requested
a
12­
month
averaging
period
for
compliance
for
pultrusion.
The
commenters
stated
that
pultruders
should
be
able
to
use
a
combination
of
preform
injection,
wet
area
enclosures,
direct
die
injection,
and
``
no
control''
to
meet
the
60
percent
HAP
emissions
reduction
requirement
for
existing
sources.
The
commenters
pointed
out
that
HAP
emissions
credits
could
be
earned
to
offset
the
processing
of
products
with
an
open
bath
and
``
no
control.''
According
to
the
commenters,
without
averaging,
facilities
will
be
forced
to
discontinue
manufacturing
products
that
require
constant
open
access
(
for
example,
certain
complex
profiles)
or
to
shut
down
any
processing
line
when
there
is
an
extended
period
of
processing
adjustments
(
which
require
open
access
to
the
line).
Response:
We
agree
that
averaging
will
add
some
flexibility
for
you
to
comply
with
the
final
rule
without
increasing
HAP
emissions.
Therefore,
for
existing
sources
we
have
included
an
averaging
option.
For
purposes
of
averaging,
we
have
assigned
wet
area
enclosures
a
60
percent
HAP
emissions
reduction,
and
direct
die
injection
and
preform
injection
a
90
percent
HAP
emissions
reduction.
Comment:
Several
commenters
requested
that
the
60
percent
emission
reduction
requirement
for
existing
sources,
which
is
based
in
the
use
of
a
wet
area
enclosure,
be
replaced
with
a
work
practice
standard
of
air
flow
management.
They
stated
it
was
impossible
to
apply
wet
area
enclosures
to
these
large
parts
because
of
accessibility
concerns.
Large
parts
require
almost
constant
access
because
they
are
extremely
complex.
The
other
control
options
for
existing
sources,
preform
injection
and
direct
die
injection,
have
also
not
been
demonstrated
on
these
large
parts.
They
suggested
a
definition
for
large
parts,
which
was
parts
with
1,000
or
more
reinforcements
and
at
least
a
60
square
inch
cross
sectional
area.
Response:
We
agree
that
wet
area
enclosures,
which
form
the
basis
of
the
existing
source
floor,
are
not
feasible
for
large
parts
as
defined
in
the
comment.
Therefore,
we
developed
a
separate
existing
source
MACT
floor
for
large
pultruded
parts.
A
review
of
the
available
data
indicates
air
flow
management
(
as
described
in
more
detail
in
Table
4
to
subpart
WWWW
of
part
63)
has
been
used
to
control
emissions
from
this
process
group.
Therefore,
the
existing
source
MACT
floor
is
air
flow
management.
The
final
rule
has
been
written
to
reflect
the
new
floor.
Comment:
Many
commenters
requested
that
the
limit
on
wet
enclosure
open
times
of
30
minutes
per
shift
be
changed
to
90
minutes
per
day
to
allow
for
necessary
repairs,
start­
ups,
and
shutdowns.
Response:
We
evaluated
the
commenters'
request.
The
facilities
that
actually
set
the
floor
for
pultrusion
are
limited
to
30
minutes
per
8
hour
shift
or
45
minutes
per
12
hour
shift.
In
addition,
the
facility
may
average
over
all
pultrusion
lines.
We
have
included
averaging
provisions
across
lines
in
the
final
rule.
We
have
also
allowed
a
facility
to
have
the
doors
and
covers
open
90
minutes
per
day
providing
the
machine
is
operated
three
8­
hour
shifts
or
two
12­
hour
shifts.
Comment:
Three
commenters
claimed
that
the
height
restriction
on
wet
area
enclosures
is
not
practical
because
it
does
not
allow
room
above
the
highest
part
to
make
adjustments
to
the
process
or
equipment.
According
to
the
commenters,
the
actual
height
of
the
wet
area
enclosure
has
no
impact
on
HAP
emissions
because
the
puller
window
is
the
controlling
factor,
and
styrene
emissions
will
remain
near
the
bath
without
air
flow.
The
commenters,
therefore,
requested
that
the
restriction
be
removed.
Response:
We
have
no
data
to
suggest
that
limiting
the
height
of
the
enclosure
affects
the
amount
of
HAP
emissions
reduction.
Therefore,
we
did
not
include
the
height
restrictions
on
the
wet
area
enclosures
in
the
final
rule.
Comment:
Commenters
requested
that
capture
and
control
not
be
required
for
sources
engaged
in
SMC
manufacturing.
The
commenter
stated
that
EPA's
proposal
for
control
is
based
on
one
source
and,
according
to
the
commenter,
that
source
has
found
that
they
cannot
operate
the
SMC
operation
and
comply
with
EPA
Method
204
of
appendix
M
of
40
CFR
part
51.
A
second
commenter
stated
that
their
SMC
operation
is
permitted
by
Ohio
EPA
as
a
PTE
with
all
HAP
emissions
vented
to
a
thermal
oxidizer.
They
have
found
it
expensive
to
maintain
the
PTE
and
control
device
and
may
be
required
to
install
additional
monitors
at
great
expense.
Response:
For
existing
sources,
the
final
rule
does
not
require
capture
and
control
for
SMC
manufacturing.
For
new
sources,
however,
the
floor
is
95
percent
reduction
and
we
do
not
have
the
flexibility
to
change
the
floor.
Most
of
the
comments
raised
by
the
commenters
relate
to
the
cost
of
PTE
and
thermal
oxidizers.
However,
costs
may
not
be
considered
in
setting
the
floor.
Additionally,
the
problems
with
compliance
noted
by
one
commenter
do
not,
in
themselves,
indicate
that
new
sources
cannot
be
designed
and
operated
to
meet
the
95
percent
control
requirement.
For
example,
the
facility
states
that
they
must
open
a
large
overhead
door
to
operate
their
second
SMC
machine.
In
a
new
facility,
the
plant
layout
can
be
designed
where
large
doors
are
not
required
to
be
continually
open.
Therefore,
the
final
rule
retains
the
requirement
of
95
percent
capture
and
control
for
SMC
manufacturing
at
new
sources
that
exceed
the
100
tpy
of
HAP
emissions
threshold.
Comment:
One
commenter
noted
that
an
alternative
to
meeting
the
95
percent
HAP
emissions
reduction
requirement
is
provided
for
some
operations
and
requests
that
an
alternate
HAP
emissions
limit
be
provided
for
SMC
manufacturing.
An
alternative
HAP
emissions
limit
allows
SMC
manufacturers
to
utilize
pollutionprevention
efforts
that
have
already
been
implemented
and
encourages
the
use
of
future
pollution­
prevention
efforts.
Response:
For
SMC
manufacturing,
we
have
incorporated
a
HAP
emissions
limit
of
2.4
lb/
ton
as
a
compliance
alternative
to
the
95
percent
control
requirement
in
the
final
rule.
Comment:
A
number
of
commenters
expressed
concerns
about
the
floor
level
of
control
for
SMC
manufacturing
that
is
based
on
several
work
practices.
They
stated
that
the
requirement
to
cover
doctor
boxes
should
be
deleted
because
the
boxes
have
to
be
open
for
machine
operators
to
monitor
paste
levels.
They
also
mentioned
that
folding
the
edges
of
the
SMC
had
proved
to
create
problems
for
some
facilities
that
had
tried
the
practice.
Finally,
they
stated
that
the
requirement
to
enclose
the
SMC
in
nylon
film
should
actually
say
nyloncontaining
film.
Response:
We
evaluated
the
basis
for
the
MACT
floor
by
reviewing
all
of
the
data
available
prior
to
proposal
and
contained
in
the
public
comment
letters.
On
the
basis
of
this
review,
we
discovered
that
the
MACT
floor
at
proposal
did
not
accurately
reflect
the
actual
work
practices
currently
being
used.
Therefore,
we
changed
the
floor

Rules
and
Regulations
for
both
new
and
existing
sources
to
cover
or
enclose
the
resin
transport
system
up
to
the
doctor
box
and
use
nylon­
containing
film
to
enclose
the
SMC.
Based
on
the
practices
at
the
best
controlled
similar
source,
these
work
practices
also
apply
to
new

that
are
above
the
100
tpy
threshold.
Comment:
Several
commenters
requested
that
the
requirement
for
``
no
visible
gaps
in
mixer
covers''
be
revised
to
allow
reasonable
and
necessary
openings.
In
general,
they
stated
that
mixing
vessels
must
have
some
opening
or
vents
to
allow
air
to
enter
or
leave
the
vessel
when
materials
are
added
or
removed,
or
when
the
contained
material
expands
or
contracts
due
to
changes
in
temperature.
Commenters
also
noted
necessary
clearance
for
mixing
shafts
and
other
instrumentation
are
essential
and
suggested
allowing
a
gap
of
one
inch.
An
additional
commenter
stated
that
they
have
several
holding
tanks
that
are
continuously
agitated
to
prevent
settling.
They
requested
that
we
add
clarifying
language
to
the
definition
of
mixers
to
exclude
tanks
that
are
only
agitated
to
prevent
settling.
Response:
Based
on
our
review
of
the
available
data
on
the
current
industry
control
on
mixing
tanks,
we
found
that
the
proposed
rule
is
more
stringent
than
the
floor
and
that
to
allow
some
visible
gaps
around
shafts,
etc.,
is
consistent
with
the
data
available
to
set
the
floor.
Therefore,
we
have
written
the
final
rule
to
allow
no
more
than
one
inch
of
visible
gap
around
mixing
shafts
and
any
required
instrumentation.
With
regard
to
the
request
to
exempt
tanks
that
are
agitated
only
to
prevent
settling,
concern
was
that
the
mixing
shafts
required
clearance.
Because
we
have
added
a
provision
to
allow
up
to
a
one
inch
clearance
around
the
agitator
shafts,
this
concern
has
been
addressed
and
the
suggested
exemption
for
these
specific
types
of
mixers
is
not
warranted.
Therefore,
the
final
rule
does
not
include
an
exemption
for
tanks
that
agitate
only
to
prevent
settling.
Comment:
Several
commenters
requested
that
the
rule
allow
active
venting
under
three
conditions:
when
adding
filler;
when
using
nitrogen
blanketing;
and
prior
to
opening
a
mixer.
Several
commenters
stated
that
when
powders
are
added
to
mixing
tanks,
vent
gases
are
directed
to
a
dust
collector
to
protect
employees.
One
commenter
stated
that
you
cannot
capture
dust
without
actively
venting.
The
commenter
suggests
that
the
proposed
rule
allow
active
venting
as
part
of
the
material
addition
process.
Two
commenters
actively
vent
covered
mixers
at
very
low
flow
through
a
dust
collector.
The
active
flow
results
from
nitrogen
flowing
through
the
air
space
for
safety
reasons
(
to
prevent
vapor
buildup).
Based
on
stack
test
results,
HAP
emissions
under
these
conditions
were
found
to
be
very
low
(
0.000292
lb
styrene/
lb
styrene
available).
For
these
reasons,
active
venting
for
safety
reasons,
using
an
inert
gas
purge,
and
at
low
flow,
should
be
allowed
for
covered
mixers.
Another
commenter
stated
that
some
mixing
operations
use
nitrogen
blanketing
for
safety
(
to
prevent
formation
of
flammable
atmospheres).
These
sources
have
an
incentive
to
limit
use
of
nitrogen
blanketing
because
of
cost;
so,
HAP
emissions
will
be
negligible.
Two
commenters
also
requested
that
the
rule
allow
venting
just
before
adding
materials
to
clear
out
vapors
prior
to
opening
covers
and
to
allow
venting
just
after
adding
powders
to
capture
residual
dust
in
the
vapor
space.
One
commenter
also
asked
that
the
term
``
active
venting''
be
defined
in
the
rule.
Response:
We
believe
that
most
HAP
emissions
that
result
from
mixing
operations
occur
when
active
mixing
is
taking
place.
Also,
based
on
the
data
used
to
set
the
MACT
floor,
the
facilities
that
responded
that
mixers
have
no
active
venting
meant
that
the
mixer
was
covered
and
not
vented
during
mixing.
As
a
result,
we
have
written
the
rule
requirement
to
read
``
close
any
mixer
vents
when
actual
mixing
is
occurring,
except
that
venting
is
allowed
during
addition
of
materials,
or
as
necessary
prior
to
adding
materials
or
opening
the
cover
for
safety.''
Because
we
have
removed
the
term
``
active
venting,''
no
definition
of
this
term
is
required.
Comment:
One
commenter
believes
that
covers
should
be
required
instead
of
add­
on
control
for
larger
mixing
operations.
According
to
the
commenter,
covers
can
reduce
HAP
emissions
by
84.8
percent
to
96
percent.
The
commenter
then
maintains
that
the
incremental
HAP
emissions
reduction
from
oxidation
cannot
justify
the
cost
and
energy
use
of
control
when
compared
to
covers.
The
commenter
notes
that
there
are
some
facilities
in
EPA's
database
that
use
add­
on
controls
for
mixing.
However,
according
to
the
commenter,
the
control
in
all
cases
is
incidental
to
the
use
of
the
add­
on
control
for
other
operations
in
the
facility.
Therefore,
the
commenter
believes
that
add­
on
control
is
not
the
best
control
for
mixing,
and
the
final
rule
should
require
covers
instead
of
add­
on
controls
for
all
mixing
operations.
Response:
The
reasons
for
why
HAP
emissions
are
being
controlled
is
usually
not
considered
in
the
setting
of
MACT
standards.
Further,
we
disagree
with
the
commenter's
characterization
of
the
control
of
mixing
HAP
emissions
as
``
incidental.''
We
do
not
agree
that
the
data
provided
support
the
claim
of
85
to
96
percent
control
using
covers.
Therefore,
we
have
not
written
the
rule
as
requested
by
the
commenter.
New
sources
that
exceed
the
100
tpy
HAP
emissions
threshold
will
still
have
to
cover
the
mixing
tanks
and
control
their
HAP
emissions
from
mixing
by
95
percent,
which
is
the
new
source
floor
level
of
control.
Comment:
Two
commenters
suggested
that
the
definition
of
compression
molding
be
changed
to
include
a
process
where
resin
paste
is
added
to
the
reinforcement
at
the
press
and
to
include
the
use
of
in­
mold
coating
(
IMC).
According
to
the
commenters,
the
resin
paste
process
is
similar
to
the
use
of
SMC
and
BMC
because
there
is
no
exposure
of
HAP­
containing
material,
except
where
the
charge
is
being
prepared
and
placed
in
the
mold.
The
controls
for
this
process
are
the
same
as
those
available
for
SMC
and
BMC
(
i.
e.
limiting
the
quantity
of
exposed
materials
to
that
which
is
required
for
one
press
cycle).
In­
mold
coating
is
a
process
where
HAPcontaining
materials
are
mixed
with
catalyst
and
then
injected
into
the
mold
cavity
after
the
molding
cycle
has
started.
The
IMC
reduces
the
need
for
post­
mold
coating
(
painting)
operations.
The
controls
available
for
IMC
are
the
same
as
those
generally
available
for
mixing
operations.
Response:
We
have
modified
the
definition
of
closed
molding
to
include
these
processes.
Comment:
Several
commenters
requested
that
the
work
practice
standard
requiring
closed
molding
operations
to
uncover,
unwrap,
or
expose
only
one
charge
per
mold
cycle
per
machine
be
revised
so
that
a
charge
is
defined
as
the
amount
of
materials
required
to
charge
the
mold(
s)
for
each
machine
cycle.
Some
machines
have
more
than
one
mold,
and
limiting
the
amount
of
material
would
cause
a
bottleneck
in
production
capacity.
One
commenter
added
that
the
rule
should
allow
multiple
charges
to
be
loaded
into
the
hopper,
provided
the
hopper
is
kept
covered
between
loading
operations
and
that
the
unlimited
use
of
slitting
machines
to
unwrap,
cut,
and
prepare
charges
should
be
permitted,
provided
that
the
charges
are
then
covered
or
placed
in
a
closed
container
prior
to
use
at
the
press.
Response:
We
agree
that
where
multiple
charges
are
required
for
a
single
mold
cycle,
the
rule
should
allow
them
to
be
prepared
at
the
same
time

Therefore,
we
have

the
final

to

per
the
commenter's
suggestion
and
to
require
that
multiple

as

Comment:
Many
commenters
noted
in
the
proposed
rule
that
polymer
casting
mixing
operations
in
containers
of
21
gallons
or
less
may
be
open
while
active
mixing
occurs
and
requested
that
this
exemption
be
increased.
The
commenters
note
that
many
are
using
350
lb
containers,
which
is
equivalent
to
21.6
gallons.
According
to
the
commenters,
the
mixing
process
uses
an
electric
mixer
and
requires
frequent
manual
scraping
of
the
sides,
and
a
requirement
to
cover
the
mixer
would
present
a
productivity
disadvantage.
Response:
Changing
the
volume
exemption
from
21
to
21.6
gallons
would
be
consistent
with
the
intent
of
the
proposed
exemption.
The
surface
area
of
exempt
mixers
is
a
more
important
parameter
because
it
is
directly
related
to
the
amount
of
HAP
emissions
that
would
occur.
Therefore,
we
have
included
this
exemption
in
the
final
rule
but
have
changed
the
exemption
parameter
to
500
square
inches
of
surface
area.
This
change
should
allow
the
21.6
gallon
mixers,
commonly
used
in
this
industry,
to
be
exempt
from
the
requirement
to
cover
the
mixer.
Comment:
One
commenter
noted
that
worker
safety,
fire
prevention,
and
product
quality
requirements
necessitate
limited
active
venting
of
HAP­
containing
materials
storage
vessels,
covered
mixers,
and
material
conveyance
enclosures.
Some
facilities
store
resins
in
bulk
tanks
with
passive
atmospheric
venting.
Problems
arise
from
resin
contact
with
the
water
vapor
in
the
atmosphere.
Polymerization
occurs
on
side
walls,
vents,
and
transfer
pipes.
Vents,
especially
conservation
vents,
can
plug,
threatening
the
tank's
structural
integrity.
Nitrogen
blanketing
is
used
by
some
facilities
to
solve
these
problems.
Nitrogen
blanketing
is
also
used
to
inert
the
head
space
in
bulk
HAP­
containing
materials
storage
tanks
for
fire
prevention.
Another
commenter
requested
clarifying
language
to
allow
passive
vents
for
bulk
HAP­
containing
materials
storage
tanks.
The
vents
are
small
to
allow
for
breathing
of
the
tanks
as
they
are
filled
and
emptied.
These
vents
are
required
under
OSHA
to
prevent
pressure
build­
up
and
to
reduce
the
chances
of
explosions
and
major
leaks
or
spills.
The
annual
breathing
losses
from
all
eight
of
this
commenter's
tanks
are
less
than
1
tpy.
A
third
commenter
suggested
that
the
rule
be
changed
to
allow
venting
from
HAP­
containing
materials
storage
vessels.
Response:
We
did
not
intend
to
prohibit
bulk
HAP­
containing
materials
storage
tanks
from
venting
to
the
atmosphere
for
safety.
The
final
rule
has
been
written
to
clarify
this.
However,
it
is
not
our
intent
to
allow
venting
from
all
HAP­
containing
materials
storage
vessels
because
the
safety
concerns
commenters
raised
are
limited
to
bulk
HAP­
containing
materials
storage
vessels.
Thus,
the
final
rule
prohibits
venting
from
HAP­
containing
materials
storage
vessels
other
than
bulk
storage
tanks.
Comment:
One
commenter
noted
that
the
proposed
rule
would
require
that
HAP­
containing
materials
storage
containers
be
kept
closed
or
covered,
except
when
adding
or
removing
materials.
The
commenter
claims
this
provision
is
not
workable.
Response:
We
believe
that
covering
HAP­
containing
materials
storage
containers
is
a
simple
and
cost­
effective
way
to
reduce
styrene
evaporation.
We
also
note
that
over
200
facilities
that
reported
information
on
storage
stated
that
HAP­
containing
materials
storage
containers
are
covered
or
closed.
This
provision
has
been
written
in
the
final
rule.
Comment:
Several
commenters
requested
that
HAP
cleaners
be
allowed
when
used
in
a
closed
system
or
covered
tank.
The
reasons
were
that
aggressive
cleaners
were
necessary
due
to
the
presence
of
cured
resin
on
some
surfaces,
and
that
it
was
important
to
use
a
cleaner
that
would
not
cause
contamination
problems.
They
stated
that
HAP
emissions
from
these
closed
systems
were
minimal,
and
in
many
cases,
the
styrene
used
for
cleaning
was
recycled
to
the
process
as
a
raw
material.
Response:
The
proposed
rule
allowed
the
use
of
HAP
cleaners
to
remove
cured
resin
from
application
equipment
because
of
the
difficulty
associated
with
removing
the
cured
resin.
One
commenter
in
particular
identified
other
equipment
used
in
the
process
on
which
cured
resin
may
occur.
We
note,
as
the
commenters
have,
that
styrene
is
the
main
HAP
used
in
the
reinforced
plastic
composites
industry
and
can
be
reused
in
the
process
without
contaminating
the
end
products.
Therefore,
we
believe
that
the
commenters'
requests
are
reasonable
and
have
written
the
final
rule
to
expand
the
definition
of
``
application
equipment''
and
to
allow
the
use
of
HAP­
containing
cleaners
in
closed
systems
(
including
covered
tanks).

If
you
use
an
add­

to
control
HAP

you
will
need
to
comply
with
certain
provisions
in

subpart
SS,
for
add­
on

The
standards
in

cited
by
the
final

NESHAP,
are
applicable
to
most
sources
using
an
add­

The

cite
these

B.
NESHAP
for
Boat
Manufacturing
(
40
CFR
Part
63,
Subpart
VVVV)

The
final
NESHAP
for
Boat
Manufacturing
were
published
on
August
22,
2001
(
66
FR
44218).
There
is
a
potential
overlap
between
facilities
that
produce
reinforced
plastic
composites
if
they
also
produce
boat
hulls,
boat
decks,
or
molds
for
boat
hulls
and
decks.
We
have
included
provisions
in
the
Reinforced
Plastic
Composites
NESHAP
to
clarify
where
the
Reinforced
Plastic
Composites
NESHAP
apply,
and
where
the
Boat
Manufacturing
NESHAP
(
40
CFR
part
63,
subpart
VVVV)
apply.

C.
NESHAP
for
Plastic
Parts
and
Products
(
Surface
Coating)

There
are
currently
NESHAP
under
development
for
proposal
that
will
regulate
coating
of
plastic
parts
and
products.
The
Small
Business
Advocacy
Review
Panel,
convened
for
the
Reinforced
Plastic
Composites
NESHAP,
recommended
that
we
consider
the
interaction
of
the
Reinforced
Plastic
Composites
NESHAP
and
the
Plastic
Parts
and
Products
NESHAP.
The
Plastic
Parts
and
Products
NESHAP
may
potentially
affect
facilities
that
produce
reinforced
plastic
parts
and
then
apply
a
coating
to
the
finished
parts.
We
have
coordinated
with
this
project
and
have
determined
that
there
should
be
no
overlap
(
i.
e.,
specific
operations
covered
by
today's
final
NESHAP
should
not
also
be
covered
in
the
Plastic
Parts
and
Products
NESHAP).
We
have
not
determined
any
requirements
of
today's
final
NESHAP
that
would
overlap,
conflict,
or
cause
a
duplication
of
effort.

Operating
Permit
Program
Under
the
operating
permit
program
codified
at
40
CFR
part
70
and
40
CFR
part
71,
all
major
sources
subject
to
standards
under
section
111
or
112
of
the
CAA
must
obtain
an
operating
permit
(
See
§
§
70.3(
a)(
1)
and
71.3(
a)(
1)).
Therefore,
all
major
sources
subject
to
the
final
NESHAP
must
obtain
an
operating
permit.
Some
reinforced
plastic
composites
production
facilities
may
be
major
sources
based
solely
on
their
potential
to
emit,
even
though
their
actual
HAP
emissions
are
below
the
major
source
level.
These
facilities
may
choose
to
obtain
a
federally
enforceable
limit
on
their
potential
to
emit
so
that
they
are
no
longer
considered
major
sources
subject
to
the
final
NESHAP.
Sources
that
opt
to
limit
their
potential
to
emit
(
e.
g.,
limits
on
operating
hours
or
amount
of
material
used)
are
referred
to
by
the
EPA
as
``
synthetic
area''
sources.
To
become
a
synthetic
area
source,
you
must
contact
your
local
permitting
authority
to
obtain
an
operating
permit
with
the
appropriate
operating
limits.
These
limits
must
be
obtained
prior
to
the
compliance
date
for
existing
sources,
which
is
April
21,
2006.
These
operating
limits
will
then
be
federally
enforceable
under
40
CFR
70.6(
b).

VII.
Statutory
and
Executive
Order
Reviews
A.
Executive
Order
12866,
Regulatory
Planning
and
Review
Under
Executive
Order
12866
(
58
FR
51735,
October
4,
1993),
we
must
determine
whether
this
regulatory
action
is
``
significant''
and
therefore
subject
to
Office
of
Management
and
Budget
(
OMB)
review
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
entitlements,
grants,
user
fees,
or
loan
programs
or
the
rights
and
obligations
of
recipients
thereof;
or
(
4)
Raise
novel
legal
or
policy
issues
arising
out
of
legal
mandates,
the
President's
priorities,
or
the
principles
set
forth
in
the
Executive
Order.
Pursuant
to
the
terms
of
Executive
Order
12866,
OMB
notified
EPA
at
proposal
that
it
considered
this
rulemaking
a
``
significant
regulatory
action''
within
the
meaning
of
the
Executive
Order.
The
EPA
submitted
the
proposed
rule
to
OMB
for
review.
Changes
made
in
response
to
suggestions
or
recommendations
from
OMB
are
documented
and
included
in
the
public
record.
The
OMB
has
informed
EPA
that
it
no
longer
considers
this
action
significant.
Therefore,
it
is
not
subject
to
further
OMB
review.
The
OMB
did
request
a
copy
of
the
final
regulation
and
preamble
prior
to
publication.
However,
they
did
not
request
any
changes
in
the
final
rule.

B.

44
U.

The
information
requirements
are
not
enforceable
until
OMB
approves
them.
The
final
rule
contains
monitoring,
reporting,
and
recordkeeping
requirements.
These
notices
and
reports
are
the
minimum
needed
by
us
to
determine
if
you
are
subject
to
the
NESHAP
and
whether
you
are
in
compliance.
These
recordkeeping
requirements
are
the
minimum
necessary
to
determine
initial
and
ongoing
compliance.
Based
on
reported
information,
we
would
decide
which
reinforced
plastic
composites
facilities
and
what
records
or
processes
should
be
inspected.
The
recordkeeping
and
reporting
requirements
are
consistent
with
the
General
Provisions
of
40
CFR
part
63.
These
recordkeeping
and
reporting
requirements
are
specifically
authorized
by
section
114
of
the
CAA
(
42
U.
S.
C.
7414).
All
information
submitted
to
us
for
which
a
claim
of
confidentiality
is
made
will
be
safeguarded
according
to
our
policies
in
40
CFR
part
2,
subpart
B.
We
expect
the
final
rule
to
affect
a
total
of
approximately
488
facilities
over
the
first
3
years.
This
includes
435
existing
facilities,
and
53
new
reinforced
plastic
composites
facilities
that
will
become
subject
to
the
final
NESHAP
during
the
first
3
years.
The
estimated
average
annual
burden
for
the
first
3
years
after
promulgation
of
the
final
NESHAP
for
industry
and

Regulatory
Flexibility
Analysis
The
EPA
has
prepared
a
Final
Regulatory
Flexibility
Analysis
(
FRFA)
in
connection
with
the
final
rule.
For
purposes
of
assessing
the
impacts
of
today's
final
rule
on
small
entities,
small
entity
is
defined
as:
(
1)
A
small
business
ranging
from
500
to
1,000
employees
as
defined
by
the
Small
Business
Administration's
size
standards;
(
2)
a
small
governmental
jurisdiction
that
is
a
government
of
a
city,
county,
town,
school
district
or
special
district
with
a
population
of
less
than
50,000;
and
(
3)
a
small
organization
that
is
any
not­
for­
profit
enterprise
which
is
independently
owned
and
operated
and
is
not
dominant
in
its
field.

In
accordance
with
section
603
of
the
RFA,
EPA
prepared
an
initial
regulatory
flexibility
analysis
(
IRFA)
for
the
proposed
rule
and
convened
a
Small
Business
Advocacy
Review
Panel
to
obtain
advice
and
recommendations
of
representatives
of
the
regulated
small
entities
in
accordance
with
section
609(
b)
of
the
RFA
(
see
66
FR
40324).
A
detailed
discussion
of
the
Panel's
advice
and
recommendations
is
found
in
Docket
ID
No.
OAR
 
2003
 
0003
(
formerly
Docket
No.
A
 
94
 
52).
A
summary
of
the
panel's
recommendations
is
presented
below.
We
have
also
prepared
a
FRFA
for
today's
rule.
The
FRFA
addresses
the
issues
raised
by
public
comments
on
the
IRFA.
The
FRFA
is
available
in
the
docket
and
is
summarized
below.
Section
112
of
the
CAA
requires
us
to
list
categories
and
subcategories
of
major
sources
and,
in
some
cases,
area
sources
of
HAP
and
to
establish
NESHAP
for
the
listed
source
categories
and
subcategories.
The
Reinforced
Plastic
Composites
Production
source
category
(
major
sources
only)
was
included
on
the
initial
list
of
source
categories
published
on
July
16,
1992
(
57
FR
31576).
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
objective
of
the
final
rule
is
to
apply
standards
based
on
MACT
to
all
major
sources
in
this
source
category.
The
criteria
used
to
establish
MACT
are
contained
in
section
112(
d)
of
the
CAA.
We
received
several
comments
on
the
economic
analysis
for
the
proposed
rule.
However,
these
comments
related
to
the
general
analysis
methodology
and
were
mainly
focused
on
the
above­
the­
floor
requirements.
These
requirements
did
not
impact
any
small
businesses
in
our
analysis.
We
had
no
comments
specifically
in
the
IRFA.
Based
on
SBA
size
definitions
and
reported
sales
and
employment
data,
we
identified
279
of
the
357
companies
owning
reinforced
plastic
composites
facilities
as
small
businesses.
Although
small
businesses
represent
almost
80
percent
of
the
companies
within
the
source
category,
they
are
expected
to
incur
53
percent
of
the
total
industry
compliance
costs
of
$
21.5
million.
The
average
total
annual
compliance
cost
is
projected
to
be
$
40,000
per
small
company,
compared
to
the
industry
average
of
$
60,000
per
company.
Under
the
final
standards,
the
mean
annual
compliance
cost,
as
a
share
of
sales,
for
small
businesses
is
0.8
percent,
and
the
median
is
0.5
percent,
with
a
range
of
0.01
to
9.6
percent.
We
estimate
that
24
percent
of
small
businesses
(
or
67
firms)
may
experience
an
impact
greater
than
1
percent
of
sales,
and
5
percent
of
small
businesses
(
or
14
firms)
may
experience
an
impact
greater
than
3
percent
of
sales.
We
also
performed
an
economic
impact
analysis
(
EIA)
that
accounted
for
firm
behavior
to
provide
an
estimate
of
the
facility
and
market
impacts
of
the
final
rule.
This
industry
is
characterized
by
profit
margins
of
3
to
4
percent.
Small
businesses
were
found
to
have
higher
per­
unit
production
costs
under
baseline
conditions
and
incur
slightly
higher
per­
unit
compliance
costs.
As
a
result
of
these
factors,
the
economic
analysis
indicates
that
12
percent
of
facilities
owned
by
small
business
are
at
risk
of
closure
because
of
the
final
rule.
Note
that
this
number
is
slightly
higher
then
the
estimate
at
proposal,
which
was
10
percent.
This
change
is
not
due
to
any
change
in
stringency
of
the
rule
as
applied
to
small
businesses.
It
is
due
to
the
reduction
in
stringency
of
the
rule
for
large
businesses.
Although
any
facility
closures
are
cause
for
concern,
the
number
of
facilities
at
risk
for
closure
would
be
the
same
if
the
final
rule
required
only
the
MACT
floor
level
of
control
for
all
facilities.
The
MACT
floor
is
the
least
stringent
level
allowed
by
statute.

Rules
and
Regulations
The
proposed
rule
contained
significant
accommodations
for
small
businesses
where
requirements
were
more
stringent
then
the
MACT
floor
for
existing
sources.
Since
these
above­
thefloor
requirements
for
existing
sources
have
been
eliminated
in
the
final
rule
for
all
process/
product
groupings
except
centrifugal
casting
and
continuous
lamination/
casting,
these
accommodations
for
small
business
are
no
longer
necessary.
Other
accommodations
originally
included
to
aid
small
businesses
were
extended
to
all
businesses
at
proposal
and
have
been
retained
in
the
final
NESHAP.
In
the
proposed
rule,
there
were
different
HAP
emissions
thresholds
above
which
an
existing
facility
had
to
comply
with
more
stringent
above­
thefloor
requirements
of
95
percent
capture
and
control.
This
threshold
was
250
tpy
of
HAP
emissions
for
small
businesses
and
100
tpy
for
large
businesses.
In
the
final
rule,
we
have
removed
the
abovethe
floor
capture
and
control
requirements
for
existing
sources,
except
for
those
with
centrifugal
casting
or
continuous
lamination/
casting,
and
we
have
established
a
single
threshold
of
100
tpy
for
these
existing
sources,
whether
they
are
small
or
large
businesses.
Based
on
our
analysis,
setting
the
threshold
at
100
tpy
for
these
sources,
rather
than
retaining
the
proposed
100
tpy
for
large
businesses
and
250
tpy
for
small
businesses,
does
not
result
in
any
additional
impacts
on
small
businesses.
This
is
because
we
have
no
facilities
that
emit
over
100
tpy,
but
less
than
250
tpy,
of
HAP
from
centrifugal
casting
or
continuous
lamination/
casting
processes,
and
are
small
businesses.
The
reporting
and
recordkeeping
requirements
for
these
small
businesses
include
initial
notifications,
startup
notifications
and
compliance
reports.
These
requirements
were
discussed
in
more
detail
under
the
discussion
of
the
Paperwork
Reduction
Act
above.
We
estimate
that
301
existing
facilities
owned
by
small
businesses
will
be
impacted
by
these
requirements,
and
53
new
facilities
owned
by
small
businesses
will
be
impacted
in
the
first
3
years.
The
professional
skills
required
to
complete
these
reports
include
the
ability
to
calculate
HAP
emissions
and
resin
use
and
read
and
follow
report
format
guidance.
All
facilities
impacted
by
the
final
rule
are
predicted
to
have
personnel
with
the
necessary
skills
because
they
would
need
these
skills
to
comply
with
other
regulatory
requirements,
such
as
Toxic
Release
Inventory
(
TRI)
reporting.
Provisions
to
minimize
the
reporting
and
recordkeeping
requirements
on
small
business
have
been
incorporated
into
the
final
rule.
These
provisions
include
allowing
the
facility
to
substantiate
resin
and
gel
coat
HAP
contents
using
MSDS
rather
than
requiring
testing
of
each
resin
and
gel
coat;
use
of
resin
purchase
records
to
determine
resin
use;
and
exemption
of
facilities
that
can
demonstrate
that
all
their
resin
and
gel
coats
comply
with
the
required
HAP
content
limits
from
the
requirement
to
keep
records
of
resin
use
and
calculate
HAP
emissions
factor
averages.
These
provisions
have
also
been
extended
to
all
companies
subject
to
today's
final
NESHAP.
These
facilities
may
also
be
subject
to
the
NESHAP
being
developed
for
plastic
parts
and
products.
There
should
be
no
duplication
of
effort
as
a
result
of
the
Reinforced
Plastic
Composites
NESHAP
and
the
Plastic
Parts
and
Products
NESHAP
being
developed
because
the
Reinforced
Plastic
Composites
NESHAP
will
cover
different
operations.
Facilities
subject
to
the
final
rule
are
also
subject
to
HAP
emissions
estimate
reporting
under
the
TRI
requirements.
In
the
final
rule,
we
could
determine
no
ways
to
combine
TRI
and
the
reporting
requirements
of
the
NESHAP
because
the
objectives
and
statutory
authorities
of
these
requirements
are
different.
As
indicated
above,
we
have
incorporated
significant
alternatives
into
the
final
rule
to
minimize
the
impact
on
small
businesses
but
still
meet
the
objectives
of
the
CAA.
As
required
by
section
609(
b)
of
the
RFA,
EPA
conducted
outreach
to
small
entities
and
convened
a
SBAR
panel
to
review
advice
and
recommendations
from
representatives
of
the
small
entities
that
potentially
would
be
subject
to
the
proposed
rule
requirements.
Consistent
with
RFA/
SBREFA
requirements,
the
panel
evaluated
the
assembled
materials
and
small­
entity
comments
on
issues
related
to
the
elements
of
the
IRFA.
A
copy
of
the
panel
report
is
included
in
the
docket.
The
panel
considered
numerous
regulatory
flexibility
options
in
response
to
concerns
raised
by
the
small
entity
representatives.
The
major
concerns
included
the
affordability
and
technical
feasibility
of
add­
on
controls,
the
resin
and
gel
coat
HAP
contents
required
to
meet
some
of
the
MACT
floors,
and
the
regulatory
treatment
of
specialty
products.
These
are
the
major
panel
recommendations
and
EPA's
response
in
today's
final
rule:
 
Recommend
setting
higher
thresholds
for
small
businesses
than
EPA
had
initially
considered
for
requirements
to
use
add­
on
controls.
Response:
In
today's
action,
EPA
has
removed
the
requirements
for
add­
on
controls
for
open
molding,
pultrusion,
SMC
and
BMC
manufacturing,
and
mixing
operations
at
existing
sources.
We
are
retaining
this
above­
the­
floor
requirement
for
centrifugal
casting
and
continuous
lamination/
casting
operations
at
existing
sources
and
setting
a
single
threshold
of
100
tpy
applicable
to
both
small
and
large
businesses.
Setting
a
common
threshold
at
100
tpy
does
not
increase
the
impacts
on
any
small
business
because
we
identified
no
small­
business
owned
sources
that
are
impacted
as
the
result
of
the
decision
to
set
a
single
threshold.
Also,
the
original
reason
for
setting
different
existing
source
thresholds
for
small
versus
large
businesses
were
the
impacts
of
the
capital
cost
of
add­
on
controls
for
open
molding,
pultrusion,
SMC
and
BMC
manufacturing,
and
mixing.
Because
existing
sources
that
have
these
operations
are
no
longer
subject
to
any
above­
the­
floor
add­
on
control
requirements,
the
original
reason
for
having
the
different
thresholds
no
longer
exists.
The
following
recommendations
were
developed
for
small
businesses,
but
were
extended
to
both
large
and
small
business
in
the
proposed
rule
and
in
the
final
rule.
 
Recommend
setting
the
new
source
floor
for
small­
owned
sources
at
the
level
of
the
existing
source
floor.
Response:
Today's
final
rule
includes
this
provision.
 
Recommend
establishing
separate
floors
for
specialty
products.
Response:
Today's
final
rule
includes
provisions
for
special
products.
 
Explore
pollution­
prevention
alternatives
to
add­
on
controls.
Response:
The
EPA
did
explore
this
possibility
with
industry
sources.
We
could
not
devise
a
workable
pollutionprevention
alternative
to
include
in
the
proposed
rule
and
requested
comment.
The
only
comments
received
on
a
pollution­
prevention
alternative
were
for
the
pultrusion
process/
product
grouping.
In
the
final
rule,
we
have
incorporated
a
new
pollutionprevention
technology
recommended
in
the
comments
as
a
compliance
alternative
for
pultrusion
operations.
 
Recommend
allowing
individual
facilities
to
use
the
same
resin
in
all
resin
application
processes.
Response:
Today's
final
rule
includes
this
provision.
 
Reconsider
the
resin
HAP
content
requirement
for
tooling
resins.
Response:
We
requested
additional
information
on
tooling
resins

and
made
significant
revisions
to
the
cost
estimates.
As
a

D.
Unfunded
Mandates
Reform
Act
Title
II
of
the
Unfunded
Mandates
Reform
Act
of
1995
(
UMRA),
Pub.
L.
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
to
State,
local,
and
tribal
governments,
in
the
aggregate,
or
to
the
private
sector,
of
$
100
million
or
more
in
any
1
year.
Before
promulgating
a
rule
for
which
a
written
statement
is
needed,
section
205
of
the
UMRA
generally
requires
us
to
identify
and
consider
a
reasonable
number
of
regulatory
alternatives
and
adopt
the
least
costly,
most
cost­
effective,
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
us
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
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
the
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
total
cost
to
the
private
sector
is
approximately
$
21.5
million
per
year
for
existing
sources
and
$
7.7
million
per
year
for
new
sources.
The
final
rule
contains
no
mandates
affecting
State,
local,
or
Tribal
governments.
Thus,
today's
final
rule
is
not
subject
to
the
requirements
of
sections
202
and
205
of
the
UMRA.
In
adopting
the
final
rule,
we
have
chosen
regulatory
alternatives
that
are
the
minimum
mandated
by
the
CAA
with
one
exception.
For
existing
centrifugal
casting
and
continuous
lamination/
casting
operations
that
emit
over
100
tpy
from
these
operations,
we
have
chosen
a
regulatory
alternative
of
95
percent
capture
and
control,
rather
than
the
minimum
level
of
control
required
under
the
CAA.
We
choose
this
alternative
because
it
results
in
additional
HAP
emissions
reductions
from
these
processes
with
a
cost
per
ton
of
HAP
reductions
we
consider
to
be
reasonable.
We
have
determined
that
the
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.

13132,
entitled
``

No
reinforced

Furthermore,
the

an
environmental
health

risk
that
we
have
reason
to
believe
may
have
a
disproportionate
effect
on
children.
If
the
regulatory
action
meets
both
criteria,
the
Agency
must
evaluate
the
environmental
health
or
safety
effects
of
the
planned
rule
on
children,
and
explain
why
the
planned
regulation
is
preferable
to
other
potentially
effective
and
reasonably
feasible
alternatives
considered
by
the
Agency.

such
that
the

required
under

the
potential

Actions
That
Significantly
Affect
Energy
Supply,

This
rule
is
not
a
``
significant
energy

as
defined
in
Executive
Order
13211,
``

That
Significantly
Affect

(

because
it
is
not

We
determined

I.
National
Technology
Transfer

Act
Section

of
the
National
Technology

(
NTTAA)
of
1995
(
Pub.
L.
No.

U.
S.
C.

note)
directs
EPA
to
use
voluntary
consensus
standards
in
their
regulatory
and
procurement
activities
unless
to
do
so
would
be
inconsistent
with
applicable
law
or
otherwise
impractical.
Voluntary
consensus
standards
are
technical
standards
(
e.
g.,
materials
specifications,
test
methods,
sampling
procedures,
business
practices)
developed
or
adopted
by
one
or
more
voluntary
consensus
bodies.
The
NTTAA
directs
EPA
to
provide
Congress,
through
annual
reports
to
the
OMB,
with
explanations
when
an
agency
does
not
use
available
and
applicable
voluntary
consensus
standards.
This
rulemaking
involves
technical
standards.
The
EPA
cites
in
this
rule
the
EPA

Consistent
with
the
NTTAA,
EPA
conducted
searches
to
identify
voluntary
consensus
standards
in
addition
to
these
EPA
methods.
No
applicable
voluntary
consensus
standards
were
identified
for
EPA
Methods
1A,
2A,
2D,
2F,
2G,
204,

The
search
and

results
have
been
documented
and
are
placed
in
Docket
ID
No.
OAR
 
2003
 
0003
(
formerly
Docket
No.
A
 
94
 
52).
Three
voluntary
consensus
standards
were
identified
as
acceptable
alternatives
to
EPA
test
methods
for
the
purposes
of
this
rule.
The
voluntary
consensus
standard
ASME
PTC
19.10
 
1981
 
Part
10,
``
Flue
and
Exhaust
Gas
Analyses,''
is
cited
in
this
rule
for
its
manual
method
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.
The
voluntary
consensus
standard,
ASTM
D6420
 
99,
``
Standard
Test
Method
for
Determination
of
Gaseous
Organic
Compounds
by
Direct
Interface
Gas
Chromatography­
Mass
Spectrometry
(
GC/
MS),''
is
appropriate
in
the
cases
described
below
for
inclusion
in
the
final
rule,
in
addition
to
the
currently
available
EPA
Method
18,
codified
at
40
CFR
part
60,
appendix
A.
Similar
to
EPA's
performance­
based
Method
18,
ASTM
D6420
 
99
is
also
a
performance­
based
method
for
measurement
of
gaseous
organic
compounds.
However,
ASTM
D6420
 
99
was
written
to
support
the
specific
use
of
highly
portable
and
automated
GC/
MS.
While
offering
advantages
over
the
traditional
Method
18,
the
ASTM
method
does
allow
some
less
stringent
criteria
for
accepting
GC/
MS
results
than
required
by
Method
18.
Therefore,
ASTM
D6420
 
99
is
a
suitable
alternative
to
Method
18
only
where
the
target
compound(
s)
are
those
listed
in
Section
1.1
of
ASTM
D6420
 
99,
and
the
target
concentration
is
between
150
parts
per
billion
volume
and
100
ppmv.
For
target
compound(
s)
not
listed
in
Section
1.1
of
ASTM
D6420
 
99,
but
potentially
detected
by
mass
spectrometry,
the
regulation
specifies
that
the
additional
system
continuing
calibration
check
after
each
run,
as
detailed
in
Section
10.5.3
of
the
ASTM
method,
must
be
followed,
met,
documented,
and
submitted
with
the
data
report
even
if
there
is
no
moisture
condenser
used
or
the
compound
is
not
considered
water
soluble.
For
target
compound(
s)
not
listed
in
Section
1.1
of
ASTM
D6420
 
99,
and
not
amenable
to
detection
by
mass
spectrometry,
ASTM
D6420
 
99
does
not
apply.
As
a
result,
EPA
is
citing
ASTM
D6420
 
99
in
subpart
WWWW
of
part
63.
The
EPA
will
also
cite
Method
18
as
a
gas
chromatography
(
GC)
option
in
addition
to
ASTM
D6420
 
99.
This
will
allow
the
continued
use
of
GC
configurations
other
than
GC/
MS.
The
EPA
requested
comments
on
proposed
compliance
demonstration
requirements
in
the
proposed
rule,
and
specifically
invited
the
public
to
identify
potentially
applicable
voluntary
consensus
standards.
The
only
comment
we
received
on
voluntary
consensus
standards
was
that
we
should
allow
the
use
of
the
vapor
suppressant
effectiveness
test
protocol
developed
by
the
CFA
to
determine
vapor
suppressant
effectiveness.
We
have
reviewed
the
information
supplied
by
the
commenter
and
have
incorporated
this
test
method,
``
Vapor
Suppressant
Effectiveness
Test
Protocol,''
into
the
final
rule
as
appendix
A
to
subpart
WWWW
of
40
CFR
part
63.
The
search
for
emissions
measurement
procedures
identified
13
additional
voluntary
consensus
standards
potentially
applicable
to
the
final
rule.
The
EPA
determined
that
11
of
these
13
standards
were
impractical
alternatives
to
EPA
test
methods
for
the
purposes
of
this
rulemaking.
Therefore,
EPA
will
not
adopt
these
standards
today.
The
reasons
for
this
determination
for
the
11
methods
are
in
the
docket.
The
following
two
voluntary
consensus
standards
identified
in
this
search
were
not
available
at
the
time
the
review
was
conducted
for
the
purposes
of
this
rulemaking
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

MFC
12M,
``

§
63.5796
What
are
the
organic
HAP
emissions
factor
equations
in
Table
1
to
this
subpart,
and
how
are
they
used
in
this
subpart?

Emissions
factors
are
used
in
this
subpart
to
determine
compliance
with
certain
organic
HAP
emissions
limits
in
Tables
3
and
5
to
this
subpart.
You
may
use
the
equations
in
Table
1
to
this
subpart
to
calculate
your
emissions
factors.
Equations
are
available
for
each
open
molding
operation
and
centrifugal
casting
operation
and
have
units
of
pounds
of
organic
HAP
emitted
per
ton
(
lb/

of
resin
or
gel
coat
applied.
These
equations
are
intended
to
provide
a
method
for
you
to
demonstrate
compliance
without
the
need
to
conduct
for
a
HAP
emissions
test.
In

How
do
I
determine
the
organic
HAP
content
of
my
resins
and
gel
coats?
In
order
to
determine
the
organic
HAP
content
of
resins
and
gel
coats,
you
may
rely
on
information
provided
by
the
material
manufacturer,
such
as
manufacturer's
formulation
data
and
material
safety
data
sheets
(
MSDS),
using
the
procedures
specified
in
paragraphs
(
a)
through
(
c)
of
this
section,
as
applicable.
(
a)
Include
in
the
organic
HAP
total
each
organic
HAP
that
is
present
at
0.1
percent
by
mass
or
more
for
Occupational
Safety
and
Health
Administration­
defined
carcinogens,
as
specified
in
29
CFR
1910.1200(
d)(
4)
and
at
1.0
percent
by
mass
or
more
for
other
organic
HAP
compounds.
(
b)
If
the
organic
HAP
content
is
provided
by
the
material
supplier
or
manufacturer
as
a
range,
you
must
use
the
upper
limit
of
the
range
for
determining
compliance.
If
a
separate
measurement
of
the
total
organic
HAP
content,
such
as
an
analysis
of
the
material
by
EPA
Method
311
of
appendix
A
to
40
CFR
part
63,
exceeds
the
upper
limit
of
the
range
of
the
total
organic
HAP
content
provided
by
the
material
supplier
or
manufacturer,
then
you
must
use
the
measured
organic
HAP
content
to
determine
compliance.
(
c)
If
the
organic
HAP
content
is
provided
as
a
single
value,
you
may
use
that
value
to
determine
compliance.
If
a
separate
measurement
of
the
total
organic
HAP
content
is
made
and
is
less
than
2
percentage
points
higher
than
the
value
for

organic
HAP
content
provided
by
the
material
supplier
or

then
you
still
may
use
the
provided
value
to
demonstrate
compliance.
If
the
measured
total
organic
HAP
content
exceeds
the
provided
value
by
2
percentage

or
more,
then
you
must
use
the
measured
organic
HAP
content
to
determine
compliance.

technology
(
new
or
existing)
whose
organic
HAP
emissions
characteristics
are
not
represented
by
the

to
this
subpart?
If
you
wish
to
use
a

application
technology
(
new
or
existing),
whose
emission
characteristics
are
not
represented
by

to
this
subpart,
you
may
use
the
procedures
in
paragraphs
(
a)
or
(
b)
of
this
section
to
establish
an
organic
HAP
emissions
factor.
This
organic
HAP
emissions
factor
may
then
be
used
to
determine
compliance
with
the
emission
limits
in
this
subpart,
and
to
calculate
facility
organic
HAP
emissions.
(
a)
Perform
a
organic
HAP
emissions
test
to
determine
a
site­
specific
organic
HAP
emissions
factor
using
the
test
procedures
in
§
63.5850.
(
b)
Submit
a
petition
to
the
Administrator
for
administrative
review
of
this
subpart.
This
petition
must
contain
a
description
of
the
resin
or
gel
coat
application
technology
and
supporting
organic
HAP
emissions
test
data
obtained
using
EPA
test
methods
or
their
equivalent.
The
emission
test
data
should
be
obtained
using
a
range
of

or
gel
coat
HAP
contents
to
demonstrate
the
effectiveness
of
the
technology
under
the
different
conditions,
and
to
demonstrate
that
the
technology
will
be
effective
at
different
sites.
We
will

organic
HAP
emissions
in
tpy
for
purposes
of
determining
which
paragraphs
in
§
63.5805
apply
to
you,
you
must
use
the
procedures
in
either
paragraph
(
a)
of

for
new
facilities
prior
to
startup,
or
paragraph
(
b)
of
this

of
these
calculations
is
discussed
in
paragraph
(
c)
of
this
section.
(
a)
For
new
facilities
prior
to
startup,
calculate
a
weighted
average
organic
HAP
emissions
factor
for
the
operations
specified
in
§
63.5805(
b)
and
(
d)
on
a
lbs/

of
resin
and
gel
coat
basis.
Base
the
weighted
average
on
your
projected
operation
for
the
12
months
subsequent
to
facility
startup.
Multiply
the
weighted
average
organic
HAP
emissions
factor
by
projected
resin
use
over
the
same
period.
You
may
calculate
your
organic
HAP
emissions
factor
based
on
the
factors
in
Table
1
to
this
subpart,
or
you
may
use
any
HAP
emissions
factor
approved
by
us,
such
as
factors
from
the
Compilation
of
Air
Pollutant
Emissions
Factors,
Volume
I:
Stationary
Point
and
Area
Sources
(
AP
 
42),
or
organic
HAP
emissions
test
data
from
similar
facilities.
(
b)
For
existing
facilities
and
new
facilities
after
startup,
you
may
use
the
procedures
in
either
paragraph
(
b)(
1)
or
(
2)
of
this
section.
If
the
emission
factors
for
an
existing
facility
have
changed
over
the
period
of
time
prior
to
their
initial
compliance
date
due
to
incorporation
of
pollution­
prevention
control
techniques,
existing
facilities
may
base
the
average
emission
factor
on
their
operations
as
they
exist
on
the
compliance
date.
If
an
existing
facility
has
accepted
an
enforceable
permit
limit
of
less
than
100
tons
per
year
of
HAP,
and
can
demonstrate
that
they
will
operate
at
that
level
subsequent
to
the

date,
the
they
can
be
deemed
to
be
below
the
100

You
may
switch
between
the
compliance
options
in
paragraphs
(

through
(
d)
of
this
section.
When
you
change
to
an
option
based
on
a
12­

you
must
base
the
average
on
the

option
you
are
currently
using
unless
you

In
this
case,
you
must

Meet
the
individual
organic

Demonstrate
that
you
meet
the
individual
organic
HAP

operation
and
for
each
centrifugal
casting
operation
type
in
Tables
3,
or
5
to
this
subpart
that
apply
to
you.
This
is
done
in
two
steps.
First,
determine
an
organic
HAP
factor
for
each
individual
resin
and
gel
coat,
application
method,
and
control
method
you
use
in
a
particular
operation.
Second,
calculate,
for
each
particular
operation
type,
a
weighted
average
of
those
organic
HAP
emissions
factors
based
on
resin
and
gel
coat
use.
Your
calculated
organic
HAP
emissions
factor
must
either
be
at
or
below
the
applicable
organic
HAP
emissions
limit
in
Tables
3
or
5
to
this
subpart
based
on
a
12­
month
rolling
average.
Use
the
procedures
described
in
paragraphs
(
a)(
1)
through
(
3)
of
this
section
to
calculate
average
organic
HAP
emissions
factors
for
each
of
your
operations.
(
1)
Calculate
your
actual
organic
HAP
emissions
factor
for
each
different
process
stream
within
each
operation
type.
A
process
stream
is
defined
as
each
individual
combination
of
resin
or
gel
coat,
application
technique,
and
control
technique.
Process
streams
within
operations
types
are
considered
different
from
each
other
if
any
of
the
following
three
characteristics
vary:
The
neat
resin
plus
or
neat
gel
coat
plus
organic
HAP
content,
the
application
technique,
or
the
control
technique.
You
must
calculate
organic
HAP
emissions
factors
for
each
different
process
stream
by
using
the
appropriate
equations
in
Table
1
to
this
subpart
for
open
molding
and
for
centrifugal
casting,
or
sitespecific
organic
HAP
emissions
factors
discussed
in
§
63.5796.
If
you
want
to
use
vapor
suppressants
to
meet
the
organic
HAP
emissions
limit
for
open
molding,
you
must
determine
the
vapor
suppressant
effectiveness
by
conducting
testing
according
to
the
procedures
specified
of
appendix
A
to
subpart
WWWW
of
40
CFR
part
63.
If
you
want
to
use
an
add­
on
control
device
to
meet
the
organic
HAP
emissions
limit,
you
must
determine
the
add­
on
control
factor
by
conducting
capture
and
control
efficiency
testing,
using
the
procedures
specified
in
§
63.5850.
The
organic
HAP
emissions
factor
calculated
from
the
equations
in
Table
1
to
this
subpart,
or
site­
specific
emissions
factors,
is
multiplied
by
the
add­
on
control

to
calculate
the
organic
HAP

after
control.
Use
Equation

type
by
calculating
the
weighted
average
of
the
individual

factors
within
each
respective
operation.
To
do
this,
sum
the

(
2)
Use
Method
2,
2A,
2C,
2D,
2F
or
2G
of
appendix
A
to
40
CFR
part
60,
as

How
do
I
calculate
annual
uncontrolled

controlled
organic
HAP
emissions
from
my
wet­
out
area(
s)
and
from
my
oven(
s)
for

operations?

To
calculate
your
annual
uncontrolled
and
controlled
organic
HAP
emissions
from
your
wet­
out
areas
and
from
your
ovens,
you
must
develop
uncontrolled
and
controlled
wet­
out
area
and
uncontrolled
and
controlled
oven
organic
HAP
emissions
estimation
equations
or
factors
to
apply
to
each
formula
applied
on
each
line,
determine
how
much
of
each
formula
for
each
end
product
is
applied
each
year
on
each
line,
and
assign
uncontrolled
and
controlled
wet­
out
area
and
uncontrolled
and
controlled
oven
organic
HAP
emissions
estimation
equations
or
factors
to
each
formula.
You
must
determine
the
overall
capture
efficiency
using
the
procedures
in
§
63.5850
to
this
subpart.
(
a)
To
develop
uncontrolled
and
controlled
organic
HAP
emissions
estimation
equations
and
factors,
you
must,
at
a
minimum,
do
the
following,
as
specified
in
paragraphs
(
a)(
1)
through
(
6)
of
this
section:
(
1)
Identify
each
end
product
and
the
thickness
of
each
end
product
produced
on
the
line.
Separate
end
products
into
the
following
end
product
groupings,
as
applicable:
corrosion­
resistant
gel
coated
end
products,
noncorrosionresistant
gel
coated
end
products,
corrosion­
resistant
nongel
coated
end
products,
and
noncorrosion­
resistant
nongel
coated
end
products.
This
step
creates
end
product/
thickness
combinations.
(
2)
Identify
each
formula
used
on
the
line
to
produce
each
end
product/
thickness
combination.
Identify
the
amount
of
each
such
formula
applied
per
year.
Rank
each
formula
used
to
produce
each
end
product/
thickness
combination
according
to
usage
within
each
end
product/
thickness
combination.
(
3)
For
each
end
product/
thickness
combination
being
produced,
select
the
formula
with
the
highest
usage
rate
for
testing.
(
4)
If
not
already
selected,
also
select
the
worst­
case
formula
(
likely
to
be
associated
with
the
formula
with
the
highest
organic
HAP
content,
type
of
HAP,
application
of
gel
coat,
thin
product,
low
line
speed,
higher
resin
table
temperature)
amongst
all
formulae.
(
You
may
use
the
results
of
the
worstcase
formula
test
for
all
formulae
if
desired
to
limit
the
amount
of
testing
required.)
(
5)
For
each
formula
selected
for
testing,
conduct
at
least
one
test
(
consisting
of
three
runs).
During
the
test,
track
information
on
organic
HAP
content
and
type
of
HAP,
end
product
thickness,
line
speed,
and
resin
temperature
on
the
wet­
out
area
table.
(
6)
Using
the
test
results,
develop
uncontrolled
and
controlled
organic
HAP
emissions
estimation
equations
(
or
factors)
or
series
of
equations
(
or
factors)
that
best
fit
the
results
for
estimating
uncontrolled
and
controlled
organic
HAP
emissions,
taking
into
account
the
organic
HAP
content
and
type
of
HAP,
end
product
thickness,
line
speed,
and
resin
temperature
on
the
wet­
out
area
table.
(
b)
In
lieu
of
using
the
method
specified
in
paragraph
(
a)
of
this
section
for
developing
uncontrolled
and
controlled
organic
HAP
emissions
estimation
equations
and
factors,
you
may
either
method
specified
in
paragraphs
(
b)(
1)
and
(
2)
of
this
section,
as
applicable.
(
1)
For
either
uncontrolled
or
controlled
organic
HAP
emissions
estimates,
you
may
use
previously
established,
facility­
specific
organic
HAP
emissions
equations
or
factors,
provided
they
allow
estimation
of
both
wet­
out
area
and
oven
organic
HAP
emissions,
where
necessary,
and
have
been
approved
by
your
permitting
authority.
If
a
previously
established
equation
or
factor
is
specific
to
the
wetout
area
only,
or
to
the
oven
only,
then
you
must
develop
the
corresponding
uncontrolled
or
controlled
equation
or
factor
for
the
other
organic
HAP
emissions
source.
(
2)
For
uncontrolled
(
controlled)
organic
HAP
emissions
estimates,
you
may
use
controlled
(
uncontrolled)
organic
HAP
emissions
estimates
and
control
device
destruction
efficiency
to
calculate
your
uncontrolled
(
controlled)
organic
HAP
emissions
provided
the
control
device
destruction
efficiency
was
calculated
at
the
same
time
you
collected
the
data
to
develop
your
facility's
controlled
(
uncontrolled)
organic
HAP
emissions
estimation
equations
and
factors.
(
c)
Assign
to
each
formula
an
uncontrolled
organic
HAP
emissions
estimation
equation
or
factor
based
on
the
end
product/
thickness
combination
for
which
that
formula
is
used.
(
d)(
1)
To
calculate
your
annual
uncontrolled
organic
HAP
emissions
from
wet­
out
areas
that
do
not
have
any
capture
and
control
and
from
wet­
out
areas
that
are
captured
by
an
enclosure
but
are
vented
to
the
atmosphere
and
not
to
a
control
device,
multiply
each
formula's
annual
usage
by
its
appropriate
organic
HAP
emissions
estimation
equation
or
factor
and
sum
the
individual
results.
(
2)
To
calculate
your
annual
uncontrolled
organic
HAP
emissions
that
escape
from
the
enclosure
on
the
wet­
out
area,
multiply
each
formula's
annual
usage
by
its
appropriate
uncontrolled
organic
HAP
emissions
estimation
equation
or
factor,
sum
the
individual
results,
and
multiply
the
summation
by
1
minus
the
percent
capture
(
expressed
as
a
fraction).
(
3)
To
calculate
your
annual
uncontrolled
oven
organic
HAP
emissions,
multiply
each
formula's
annual
usage
by
its
appropriate
uncontrolled
organic
HAP
emissions
estimation
equation
or
factor
and
sum
the
individual
results.
(
4)
To
calculate
your
annual
controlled
organic
HAP
emissions,
multiply
each
formula's
annual
usage
by
its
appropriate
organic
HAP
emissions
estimation
equation
or
factor
and
sum
the
individual
results
to
obtain
total
annual
controlled
organic
HAP
emissions.
(
e)
Where
a
facility
is
calculating
both
uncontrolled
and
controlled
organic
HAP
emissions
estimation
equations
and
factors,
you
must
test
the
same
formulae.
In
addition,
you
must
develop
both
sets
of
equations
and
factors
from
the
same
tests.

§

Continuous
Compliance
Requirements
§
63.5895
How
do
I
monitor
and
collect
data
to
demonstrate
continuous
compliance?

(
a)
During
production,
you
must
collect
and
keep
a
record
of
data
as
indicated
in
40
CFR
part
63,
subpart
SS,
if
you
are
using
an
add­
on
control
device.
(
b)
You
must
monitor
and
collect
data
as
specified
in
paragraphs
(
b)(
1)
through
(
4)
of
this
section.
(
1)
Except
for
monitoring
malfunctions,
associated
repairs,
and
required
quality
assurance
or
control
activities
(
including,
as
applicable,
calibration
checks
and
required
zero
and
span
adjustments),
you
must
conduct
all
monitoring
in
continuous
operation
(
or
collect
data
at
all
required
intervals)
at
all
times
that
the
affected
source
is
operating.
(
2)
You
may
not
use
data
recorded
during
monitoring
malfunctions,
associated
repairs,
and
required
quality
assurance
or
control
activities
for
purposes
to
this
subpart,
including
data
averages
and
calculations,
or
fulfilling
a
minimum
data
availability
requirement,
if
applicable.
You
must
use
all
the
data
collected
during
all
other
periods
in
assessing
the
operation
of
the
control
device
and
associated
control
system.
(
3)
At
all
times,
you
must
maintain
necessary
parts
for
routine
repairs
of
the
monitoring
equipment.
(
4)
A
monitoring
malfunction
is
any
sudden,
infrequent,
not
reasonably
preventable
failure
of
the
monitoring
equipment
to
provide
valid
data.
Monitoring
failures
that
are
caused
in
part
by
poor
maintenance
or
careless
operation
are
not
malfunctions.
(
c)
You
must
collect
and
keep
records
of
resin
and
gel
coat
use,
organic
HAP
content,
and
operation
where
the
resin
is
used
if
you
are
meeting
any
organic
HAP
emissions
limits
based
on
an
organic
HAP
emissions
limit
in
Tables
3
or
5
to
this
subpart.
You
must
collect
and
keep
records
of
resin
and
gel
coat
use,
organic
HAP
content,
and
operation
where
the
resin
is
used
if
you
are
meeting
any
organic
HAP
content
limits
in
Table
7
to
this
subpart
if
you
are
averaging
organic
HAP
contents.
Resin
use
records
may
be
based
on
purchase
records
if
you
can
reasonably
estimate
how
the
resin
is
applied.
The
organic
HAP
content
records
may
be
based
on
MSDS
or
on
resin
specifications
supplied
by
the
resin
supplier.
(
d)
If
you
initially
demonstrate
that
all
resins
and
gel
coats
individually
meet
the
applicable
organic
HAP
emissions
limits,
or
organic
HAP
content
limits,
then
resin
and
gel
coat
use
records
are
not
required.
However,
you
must
include
a
statement
in
each
compliance
report
that
all
resins
and
gel
coats
still
meet
the
organic
HAP
limits
for
compliant
resins
and
gel
coats
shown
in
Tables
3
or
7
to
this
subpart.
If
after
this
initial
demonstration,
you
change
to
a
higher
organic
HAP
resin
or
gel
coat,
or
increase
the
resin
or
gel
coat
organic
HAP
content,
or
change
to
a
higheremitting
resin
or
gel
coat
application
method,
then
you
must
either
again
demonstrate
that
all
resins
and
gel
coats
still
meet
the
applicable
organic
HAP
emissions
limits,
or
begin
collecting
resin
and
gel
coat
use
records
and
calculate
compliance
on
a
12­
month
rolling
average.
(
e)
For
each
of
your
pultrusion
machines,
you
must
record
all
times
that
wet
area
enclosures
doors
or
covers
are
open
and
there
is
resin
present
in
the
resin
bath.

To

for
an
operation
with

device
multiply
the
EF
above
by
the
add­
on
control
factor
calculated
using
Equation
1
of
§
63.5810.
The
organic
HAP
emissions
factors
have
units
of
lbs
of
organic
HAP
per
ton
of
resin
or
gel
coat
applied.
2
Percent
HAP
means
total
weight
percent
of
organic
HAP
(
styrene,
methyl
methacrylate,
and
any
other
organic
HAP)
in
the
resin
or
gel
coat
prior
to
the
addition
of
fillers,
catalyst,
and
promoters.
Input
the
percent
HAP
as
a
decimal,
i.
e.
33
percent
HAP
should
be
input
as
0.33,
not
33.

The
VSE
factor
means
the
percent
reduction
in
organic
HAP
emissions
expressed
as
a
decimal
measured
by
the
VSE
test
method
of
appendix
A
to
this
subpart.

This
equation
is
based
on
a
organic
HAP
emissions
factor
equation
developed
for
mechanical
atomized
controlled
spray.
It
may
only
be
used
for
automated
or
robotic
spray
systems
with
atomized
spray.
All
spray
operations
using
hand
held
spray
guns
must
use
the
appropriate
mechanical
atomized
or
mechanical
nonatomized
organic
HAP
emissions
factor
equation.
Automated
or
robotic
spray
systems
using
nonatomized
spray
should
use
the
appropriate
nonatomized
mechanical
resin
application
equation.
5
Applies
only
to
filament
application
using
an
open
resin
bath.
If
resin
is
applied
manually
or
with
a
spray
gun,
use
the
appropriate
manual
or
mechanical
application
organic
HAP
emissions
factor
equation.
6
Do
not
use
this
equation
for
determining
compliance
with
emission
limits
in
Tables
3
or
5
to
this
subpart.
To
determine
compliance
with
emission
limits
you
must
treat
all
gel
coat
as
if
it
were
applied
as
part
of
your
gel
coat
spray
application
operations.
If
you
apply
gel
coat
by
manual
techniques
only,
you
must
treat
the
gel
coat
as
if
it
were
applied
with
atomized
spray
and
use
Equation
1.
f.
to
determine
compliance
with
the
appropriate
emission
limits
in
Tables
3
or
5
to
this
subpart.
To
estimate
emissions
from
manually
applied
gel
coat,
you
may
either
include
the
gel
coat
quantities
you
apply
manually
with
the
quantities
applied
using
spray,
or
use
this
equation
to
estimate
emissions
from
the
manually
applied
portion
of
your
gel
coat.
7
These
equations
are
for
centrifugal
casting
operations
where
the
mold
is
vented
during
spinning.
Centrifugal
casting
operations
where
the
mold
is
completely
sealed
after
resin
injection
are
considered
to
be
closed
molding
operations.

If

to
apply
resin
to
an
open
centrifugal

Appendix
A
to
Subpart
WWWW
 
Test
Method
for
Determining
Vapor
Suppressant
Effectiveness
1.
Scope
and
Application
1.1
Applicability.
If
a
facility
is
using
vapor
suppressants
to
reduce
hazardous
air
pollutant
(
HAP)
emissions,
the
organic
HAP
emission
factor
equations
in
Table
1
to
this
subpart
require
that
the
vapor
suppressant
effectiveness
factor
be
determined.
The
vapor
suppressant
effectiveness
factor
is
then
used
as
one
of
the
inputs
into
the
appropriate
organic
HAP
emission
factor
equation.
The
vapor
suppressant
effectiveness
factor
test
is
not
intended
to
quantify
overall
volatile
emissions
from
a
resin,
nor
to
be
used
as
a
stand­
alone
test
for
emissions
determination.
This
test
is
designed
to
evaluate
the
performance
of
film
forming
vapor
suppressant
resin
additives.
The
results
of
this
test
are
used
only
in
combination
with
the
organic
HAP
emissions
factor
equations
in
Table
1
to
this
subpart
to
generate
emission
factors.
1.1.1
The
open
molding
process
consists
of
application
of
resin
and
reinforcements
to
the
mold
surface,
followed
by
a
manual
rollout
process
to
consolidate
the
laminate,
and
the
curing
stage
where
the
laminate
surface
is
not
disturbed.
Emission
studies
have
shown
that
approximately
50
percent
to
55
percent
of
the
emissions
occur
while
the
resin
is
being
applied
to
the
mold.
Vapor
suppressants
have
little
effect
during
this
portion
of
the
lamination
process,
but
can
have
a
significant
effect
during
the
curing
stage.
Therefore,
if
a
suppressant
is
100
percent
effective,
the
overall
emissions
from
the
process
would
be
reduced
by
45
percent
to
50
percent,
representing
the
emissions
generated
during
the
curing
stage.
In
actual
practice,
vapor
suppressant
effectiveness
will
be
less
than
100
percent
and
the
test
results
determine
the
specific
effectiveness
in
terms
of
the
vapor
suppressant
effectiveness
factor.
This
factor
represents
the
effectiveness
of
a
specific
combination
of
suppressant
additive
and
resin
formulation.
1.1.2
A
resin
manufacturer
may
supply
a
molder
with
a
vapor­
suppressed
resin,
and
employ
this
test
to
provide
the
molder
with
the
vapor
suppressant
effectiveness
factor
for
that
combination
of
resin
and
vapor
suppressant.
The
factor
qualifies
the
effectiveness
of
the
vapor
suppressant
when
the
resin
is
tested
in
the
specific
formulation
supplied
to
the
molder.
The
addition
of
fillers
or
other
diluents
by
the
molder
may
impact
the
effectiveness
of
the
vapor
suppressant.
The
formulation,
including
resin/
glass
ratio
and
filler
content,
used
in
the
test
should
be
similar
to
the
formulation
to
be
used
in
production.
The
premise
of
this
method
is
to
compare
laminate
samples
made
with
vapor
suppressant
additive
and
made
without
the
additive.
The
difference
in
emissions
between
the
two
yields
the
vapor
suppressant
effectiveness
factor.
1.1.3
The
method
uses
a
mass
balance
determination
to
establish
the
relative
loss
of
the
volatile
component
from
unsaturated
polyester
or
vinyl
ester
resins,
with
and
without
vapor
suppressant
additives.
The
effectiveness
of
a
specific
vapor
suppressant
and
resin
mixture
is
determined
by
comparing
the
relative
volatile
weight
losses
from
vapor
suppressed
and
non­
suppressed
resins.
The
volatile
species
are
not
separately
analyzed.
While
the
species
contained
in
the
volatile
component
are
not
determined,
an
extended
listing
of
potential
monomer
that
may
be
contained
in
unsaturated
polyester
or
vinyl
ester
resins
is
provided
in
Table
1.1.
However,
most
polyester
and
vinyl
ester
resin
formulations
presently
used
by
the
composites
industry
only
contain
styrene
monomer.

Summary
of
Method
2.1
Differences
in
specific
resin
and
suppressant
additive
chemistry
affect
the
performance
of
a
vapor
suppressant.
The
purpose
of
this
method
is
to
quantify
the
effectiveness
of
a
specific
combination
of
vapor
suppressant
and
unsaturated
polyester
or
vinyl
ester
resin
as
they
are
to
be
used
in
production.
This
comparative
test
quantifies
the
loss
of
volatiles
from
a
fiberglass
reinforced
laminate
during
the
roll­
out
and
curing
emission
phases,
for
resins
formulated
with
and
without
a
suppressant
additive.
A
criterion
for
this
method
is
the
testing
of
a
non­
vapor
suppressed
resin
system
and
testing
the
same
resin
with
a
vapor
suppressant.
The
two
resins
are
as
identical
as
possible
with
the
exception
of
the
addition
of
the
suppressant
to
one.
The
exact
formulation
used
for
the
test
will
be
determined
by
the
in­
use
production
requirements.
Each
formulation
of
resin,
glass,
fillers,
and
additives
is
developed
to
meet
particular
customer
and
or
performance
specifications.
2.2
The
result
of
this
test
is
used
as
an
input
factor
in
the
organic
HAP
emissions
factor
equations
in
Table
1
to
this
subpart,
which
allows
these
equations
to
predict
emissions
from
a
specific
combination
of
resin
and
suppressant.
This
test
does
not
provide
an
emission
rate
for
the
entire
lamination
process.

Test
Procedure
11.1
Test
Set­
up.
11.1.1
The
laboratory
balance
is
located
in
an
enclosure
to
prevent
fluctuations
in
balance
readings
due
to
localized
air
movement.
The
front
of
enclosure
is
open
to
permit
work
activity,
but
positioned
so
that
local
airflow
will
not
effect
balance
readings.
The
ambient
temperature
is
determined
by
suspending
the
thermometer
at
a
point
inside
the
enclosure.
11.1.2
The
bottom
of
the
aluminum
pan
is
covered
with
the
Mylar
film.
The
film
is
held
in
position
with
tape
or
by
friction
between
the
pan
and
the
film.
11.1.3
The
resin
and
pan
are
brought
to
room
temperature.
This
test
temperature
must
be
between
70
°
F
and
80
°
F.
The
testing
temperature
cannot
vary
more
than
±
2
°
F
during
the
measurement
of
test
runs.
Temperature
shall
be
recorded
at
the
same
time
weight

recorded
on
suppressed
and
non­
suppressed
test
data
sheets,
shown
in
Table
17.1.
11.1.4
The
relative
humidity
may
not
change
more
than
±
15
percent
during
the
test
runs.
This
is
determined
by
recording
the
relative
humidity
in
the
vicinity
of
the

Resin
Gel
Time/
Initiator
Percentage
11.2.1
Previous
testing
has
indicated
that
resin
gel
time
influences
the
emissions
from
composite
production.
The
testing
indicated
that
longer
the
gel
times
led
to
higher
emissions.
There
are
a
number
of
factors
that
influence
gel
time
including
initiator
type,
initiator
brand,
initiator
level,
temperature
and
resin
additives.
Under
actual
usage
conditions
a
molder
will
adjust
the
initiator
to
meet
a
gel
time
requirement.
In
this
test
procedure,
the
vapor
suppressed
and
nonvapor
suppressed
resin
systems
will
be
adjusted
to
the
same
gel
time
by
selecting
the
appropriate
initiator
level
for
each.
11.2.2
All
test
runs
within
a
test
will
be
processed
in
a
manner
that
produces
the
same
resin
gel
time
±
2
minutes.
To
facilitate
the
resin
mixing
procedure,
master
batches
of
resin
and
resin
plus
vapor
suppressant
of
resin
are
prepared.
These
resin
master
batches
will
have
all
of
the
required
ingredients
except
initiator;
this
includes
filler
for
filled
systems.
The
gel
times
for
the
tests
are
conducted
using
the
master
batch
and
adjustments
to
meet
gel
time
requirements
shall
be
made
to
the
master
batch
before
emission
testing
is
conducted.
Test
temperatures
must
be
maintained
within
the
required
range,
during
gel
time
testing.
Further
gel
time
testing
is
not
required
after
the
non­
vapor
suppressed
and
vapor
suppressed
master
batches
are
established
with
gel
times
within
±
2
minutes.
A
sufficient
quantity
of
each
resin
should
be
prepared
to
allow
for
additional
test
specimens
in
the
event
one
or
more
test
fails
to
meet
the
data
acceptance
criteria
discussed
in
Section
11.5
and
shown
in
Table
17.2.
11.2.3
The
specific
brand
of
initiator
and
the
nominal
percentage
level
recommended
by
the
resin
manufacturer
will
be
indicated
on
the
resin
certificate
of
analysis
15;
or,
if
a
unique
gel
time
is
required
in
a
production
laminate,
initiator
brand
and
percentage
will
be
determined
by
that
specific
requirement.
11.2.4
Examples:
11.2.4.1
The
resin
for
a
test
run
is
specified
as
having
a
15­
minute
cup
gel
time
at
77
°
F
using
Brand
X
initiator
at
1.5
percent
by
weight.
The
non­
suppressed
control
resin
has
a
15­
minute
gel
time.
The
suppressed
resin
has
a
gel
time
of
17­
minutes.
An
initiator
level
of
1.5
percent
would
be
selected
for
the
both
the
non­
suppressed
and
the
suppressed
test
samples.
11.2.4.2
Based
on
a
specific
production
requirement,
a
resin
is
processed
in
production
using
2.25
percent
of
Brand
Y
initiator,
which
produces
a
20­
minute
gel
time.
This
initiator
at
level
of
2.25
percent
produces
a
20
minute
gel
time
for
the
nonsuppressed
control
resin,
but
yields
a
25­
minute
gel
time
for
the
suppressed
resin
sample.
The
suppressed
resin
is
retested
at
2.50
percent
initiator
and
produces
a
21­
minute
gel
time.
The
initiator
levels
of
2.25
percent
and
2.50
percent
respectively
would
yield
gel
times
within
±
2
minutes.

with
the
aluminum
pan,
Mylar
film,
glass
mat,
and
resin
application
roller
on
the
balance
pan.
11.3.8
Resin
is
weighed
into
a
beaker,
as
calculated,
using
the
second
balance.
The
mixing
stick
should
be
tared
with
the
beaker
weight.
11.3.9
Initiator
is
weighed
into
the
resin,
as
calculated,
using
an
eyedropper
or
a
pipette,
and
the
combination
is
mixed.
11.3.10
Initiated
resin
is
poured
on
chopped
strand
mat
in
a
pe­
determined
pattern
(
see
Figure
11.6).
11.3.11
A
stopwatch
is
started
from
zero.
11.3.12
The
initial
laminate
weight
is
recorded.
11.3.13
The
plate
is
removed
from
balance
to
enable
roll­
out
of
the
laminate.
11.3.14
The
wet
laminate
is
rolled
with
the
resin
application
roller
to
completely
distribute
the
resin,
saturate
the
chopped
strand
mat,
and
eliminate
air
voids.
Roll­
out
time
should
be
in
the
range
of
2
to
316
minutes
and
vary
less
than
±
10
percent
of
the
average
time
required
for
the
complete
set
of
six
suppressed
and
six
non­
suppressed
runs.
11.3.15
Record
the
rollout
end
time
(
time
from
start
to
completion
of
rollout).
11.3.16
Place
the
resin
application
roller
on
the
edge
of
the
plate
when
rollout
is
completed.
11.3.17
Place
the
plate
back
on
the
balance
pan.
Immediately
record
the
weight.
11.3.18
For
the
first
test
in
a
series
of
six
tests,
weight
is
recorded
every
5­
minute
interval
(
suppressed
and
non­
suppressed).
The
end
of
the
test
occurs
when
three
consecutive
equal
weights
are
recorded
or
a
weight
gain
is
observed
(
the
last
weight
before
the
increased
weight
is
the
end
of
test
weight).
For
the
remaining
five
tests
in
the
series,
after
the
initial
weights
are
taken,
the
next
weight
is
recorded
30
minutes
before
the
end
of
the
test,
as
suggested
by
the
results
from
the
first
test.
It
is
likely
that
the
time
to
reach
the
end
point
of
a
suppressed
resin
test
will
be
shorter
than
the
time
required
to
complete
a
non­
suppressed
test.
Therefore,
the
time
to
start
taking
data
manually
may
be
different
for
suppressed
and
non­
suppressed
resins.

will
be
shorter
than
the
time
required
to
complete
a
non­
suppressed
test.
Therefore,
the
time
to
start
taking
data
manually
may
be
different
for
suppressed
and
non­
suppressed
resins.
11.5
Data
Acceptance
Criteria:
11.5.1
A
test
set
is
designed
as
twelve
individual
test
runs
using
the
same
resin,
initiator,
and
gel
time,
six
of
the
test
runs
use
the
resin
non­
vapor
suppressed
and
the
other
six
use
it
vapor
suppressed.
11.5.2
If
a
test
run
falls
outside
any
of
the
time,
temperature,
weight
or
humidity
variation
requirements,
it
must
be
discarded
and
run
again.
11.5.3
The
laminate
roll
out
time
for
each
individual
test
run
must
vary
less
than
±
10
percent
of
the
average
time
required
for
the
complete
set
of
six
suppressed
and
six
nonsuppressed
runs.
11.5.4
Test
temperature
for
each
test
run
must
be
maintained
within
±
2
°
F
and
the
average
must
be
between
70
°
and
80
°
F.
Refer
to
11.1.3.
11.5.5
The
difference
in
the
amount
of
resin
for
each
run
must
be
within
±
10
percent
of
the
average
weight
for
the
complete
set
of
six
suppressed
and
six
non­
suppressed
runs.
11.5.6
The
relative
humidity
from
each
test
run
must
be
within
±
15
percent
of
the
average
humidity
for
the
complete
set
of
six
suppressed
and
six
non­
suppressed
tests.
Refer
to
11.1.4
11.5.7
The
glass
content
for
each
test
set
must
be
within
±
10
percent
of
the
average
resin­
to­/
glass
ratio
for
the
complete
set
of
six
suppressed
and
six
non­
suppressed
runs.
Refer
to
12.2).
11.5.8
The
filler
content
for
each
test
of
a
test
set
must
be
within
±
5
percent
of
the
average
filler
content
for
the
complete
set
of
six
suppressed
and
six
non­
suppressed
runs.
Refer
to
12.2.
11.6
Resin
Application
Pour
Pattern:
11.6.1
To
facilitate
the
distribution
of
resin
across
the
chopped
strand
mat,
and
to
provide
consistency
from
test
to
test,
a
uniform
pour
pattern
should
be
used.
A
typical
pour
pattern
is
shown
below:

11.6.2
The
resin
is
to
be
evenly
distributed
across
the
entire
surface
of
the
chopped
strand
mat
using
the
resin
application
roller
to
achieve
a
wet
look
across
the
surface
of
the
laminate.
Pushing
excess
resin
off
the
reinforcement
and
onto
the
Mylar
sheet
should
be
avoided.
No
resin
is
to
be
pushed
more
than
1 
2
inch
beyond
the
edge
of
the
glass
mat.
If
excess
resin
is
pushed
further
from
the
glass
mat,
it
will
void
the
test
run.
As
part
of
this
process,
typical
visible
air
voids
are
to
be
eliminated
by
the
rollout
process.
If
the
pour
pattern
is
different
from
the
above,
it
must
be
recorded
and
attached
to
test
data
sheet
17.1.

Precision
Testing
13.2.1
Subsequent
to
the
initial
development
of
this
test
protocol
by
the
Composites
Fabricators
Association,
a
series
of
tests
were
conducted
in
three
different
laboratory
facilities.
The
purpose
of
this
round
robin
testing
was
to
verify
the
precision
of
the
test
method
in
various
laboratories.
Each
laboratory
received
a
sample
of
an
orthophthalic
polyester
resin
from
the
same
production
batch,
containing
48
per
cent
styrene
by
weight.
Each
testing
site
was
also
provided
with
the
same
vapor
suppressant
additive.
The
suppressant
manufacturer
specified
the
percentage
level
of
suppressant
additive.
The
resin
manufacturer
specified
the
type
and
level
of
initiator
required
to
produce
a
20
minute
gel
time.
The
target
glass
content
was
30
percent
by
weight.
13.2.2
Each
laboratory
independently
conducted
the
VSE
test
according
to
this
method.

of
the
results

Balance
Enclosure
 
The
purpose
of
the
balance
enclosure
is
to
prevent
localized
airflow
from
adversely
affecting
the
laboratory
balance.
The
enclosure
may
be
a
simple
three­
sided
box
with
a
top
and
an
open
face.
The
configuration
of
the
enclosure
is
secondary
to
the
purpose
of
providing
a
stable
and
steady
balance
reading,
free
from
the
effects
of
airflow,
for
accurate
measurements.
The
enclosure
can
be
fabricated
locally.
A
typical
enclosure
is
shown
in

Certificate
of
Analysis:
Resin
gel
time,
as
recorded
on
the
resin
certificate
of
analysis,
is
measured
using
a
laboratory
standard
gel
time
procedure.
This
procedure
typically
uses
a
100
gram
cup
sample
at
77
°
F
(
25
°
C),
a
specific
type
of
initiator
and
a
specified
percentage.
16
Roll­
out
times
may
vary
with
resin
viscosity
or
resin
additive.
The
important
aspect
of
this
step
is
to
produce
the
same
roll­
out
time
for
both
the
suppressed
and
non­
suppressed
samples.
17
While
this
test
can
be
used
with
filled
resin
systems,
the
test
is
not
designed
to
determine
the
effect
of
the
filler
on
emissions,
but
rather
to
measure
the
effect
of
the
suppressant
additive
in
the
resin
system.
When
evaluating
a
filled
system
both
the
non­
vapor
suppressed
and
vapor
suppressed
samples
should
be
formulated
with
the
same
type
and
level
of
filler.
