undertaken
to
accommodate
switching
from
the
use
of
one
ozone
depleting

CFR
part
82,
subpart
A,
appendices
A
and
B.

(
2)
Calculate
the
replaced
ODP­
weighted
amount

multiplying
the
baseline
actual
usage
(
using
the
annualized
average
of
any
24
consecutive
months
of
usage
within
the
past
10
years)
by
the
ODP
of
the
replaced
ODS.
102
(

Calculate
the
projected
ODP­
weighted
amount
by
multiplying
the
projected
future
annual
usage
of
the
new
substance
by
its
ODP.

(

G.
Applicability
procedures.

1.
To
determine
whether
a
project
constitutes
a
major
modification,
the
reviewing
authority
shall
apply
the
principles
set
out
below
in
paragraphs
IV.
G.
1(
i)
through
(
vi)
of
this
Ruling.

(
i)
Except
as
otherwise
provided
in
paragraphs
IV.
G.
2
and
3
of
this
Ruling,
and
consistent
with
the
definition
of
major
modification
contained
in
paragraph
II.
A.
5
of
this
Ruling,
a
project
is
a
major
modification
for
a
regulated
NSR
pollutant
if
it
causes
two
types
of
emissions
increases
 
a
significant
emissions
increase
(
as
defined
in
paragraph
II.
A.
24
of
this
Ruling),
and
a
significant
net
emissions
increase
(
as
defined
in
paragraphs
II.
A.
6
and
10
of
this
Ruling).
The
project
is
not
a
major
modification
if
it
does
not
cause
a
significant
emissions
increase.
If
the
project
causes
a
significant
emissions
increase,
then
the
project
is
a
major
modification
only
if
it
also
results
in
a
significant
net
emissions
increase.

The
procedure
for
calculating
(
before
beginning
actual
construction)
whether
a
significant
emissions
increase
(
i.
e.,
the
first
step
of
the
process)
will
occur
depends
upon
the
type
of
emissions
units
being
modified,

according
to
paragraphs
IV.
G.

of
this
Ruling.
The
procedure
for
calculating
(
before
beginning
actual
construction)
whether
a
significant
net
emissions
increase
will
occur
at
the
major
stationary
source
(
i.
e.,

the
second
step
of
the
process)
is
contained
in
the
definition
in
paragraph
II.
A.
6
of
this
Ruling.
Regardless
of
any
such
preconstruction
projections,
a
major
modification
results
if
the
project
causes
a
significant
emissions
increase
and
a
significant
net
emissions
increase.

(
iii)
Actual­

actual
applicability
test
for
projects
that
only
involve

A
significant
emissions
increase
of
a
regulated
NSR
pollutant
is
projected
to
occur
if
the
sum
of
the
difference
between
the
projected
actual
emissions
(
as
defined
in
paragraph
II.
A.
25
of
this
Ruling)
and
the

of
this
Ruling,
as
applicable),
for
each
existing
emissions

equals
or
exceeds
the
significant
amount
for
that
pollutant
(

for
projects
that
only
involve
construction
of
a
new
emissions
unit(

A
significant
emissions
increase
of
a
regulated
NSR
pollutant
115
is
projected
to
occur
if
the
sum
of
the
difference
between
the
potential
to
emit
(
as
defined
in
paragraph
II.
A.
3
of
this
Ruling)
from
each
new
emissions
unit
following
completion
of
the
project
and
the
baseline
actual
emissions
(
as
defined
in
paragraph
II.
A.
32(

of
this
Ruling)
of
these
units
before
the
project
equals
or
exceeds
the
significant

(
v)
Emission
test
for
projects
that
involve
Clean
Units.
For
a
project
that
will
be
constructed
and
operated
at
a
Clean
Unit
without
causing
the
emissions
unit
to
lose
its
Clean
Unit
designation,
no
emissions
increase
is
deemed
to
occur.

(
vi)
Hybrid
test
for
projects
that
involve
multiple
types
of
emissions
units.
A
significant
emissions
increase
of
a
regulated
NSR
pollutant
is
projected
to
occur
if
the
sum
of
the
emissions
increases
for
each
emissions
unit,

using
the
method
specified
in
paragraphs
IV.
G.
1(
iii)
through
(
v)
of
this
Ruling
as
applicable
with
respect
to
each
emissions
unit,
for
each
type
of
emissions
unit
equals
or
exceeds
the
significant
amount
for
that
pollutant
(
as
defined
in
paragraph
II.
A.
10
of
this
Ruling).
For
example,

if
a
project
involves
both
an
existing
emissions
unit
and
a
Clean
Unit,
the
projected
increase
is
determined
by
summing
the
values
determined
using
the
method
specified
in
paragraph
IV.

designation
applies
individually
for
each
pollutant
emitted
by
the
emissions
unit.

(
i)
Permitting
requirement.
The
emissions
unit
must
have
received
a
major
NSR
permit
within
the
past
10
years.

The
owner
or
operator
must
maintain
and
be
able
to
provide
information
that
would
demonstrate
that
this
permitting
requirement
is
met.

(
ii)
Qualifying
air
pollution
control
technologies.

Air
pollutant
emissions
from
the
emissions
unit
must
be
reduced
through
the
use
of
an
air
pollution
control
technology
(
which
includes
pollution
prevention
as
defined
under
paragraph
II.
A.
23
of
this
Ruling
or
work
practices)

that
meets
both
the
following
requirements
in
paragraphs
IV.
I.
3(
ii)(
a)
and
(
b)
of
this
Ruling.

(
a)
The
control
technology
achieves
the
LAER
level
of
emissions
reductions
as
determined
through
issuance
of
a
123
major
NSR
permit
within
the
past
10
years.
However,
the
emissions
unit
is
not
eligible
for
Clean
Unit
designation
if
the
LAER
determination
resulted
in
no
requirement
to
reduce
emissions
below
the
level
of
a
standard,
uncontrolled,
new
emissions
unit
of
the
same
type.

(
b)
The
owner
or
operator
made
an
investment
to
install
the
control
technology.
For
the
purpose
of
this
determination,
an
investment
includes
expenses
to
research
the
application
of
a
pollution
prevention
technique
to
the
emissions
unit
or
expenses
to
apply
a
pollution
prevention
technique
to
an
emissions
unit.

(
iii)
Re­
qualifying

7.
Maintaining
the
Clean
Unit
designation.
To
maintain
the
Clean
Unit
designation,
the
owner
or
operator
must
conform
to
all
the
restrictions
listed
in
paragraphs
IV.
I.
7(
i)
through
(
iii)
of
this
Ruling.
This
paragraph
IV.
I.
7
applies
independently
to
each
pollutant
for
which
the
emissions
unit
has
the
Clean
Unit
designation.
That
is,

failing
to
conform
to
the
restrictions
for
one
pollutant
affects
Clean
Unit
designation
only
for
that
pollutant.

(
i)
The
Clean
Unit
must
comply
with
the
emission
limitation(
s)
and/
or
work
practice
requirements
adopted
in
conjunction
with
the
LAER
that
is
recorded
in
the
major
NSR
permit,
and
subsequently
reflected
in
the
title
V
permit.

(
a)
The
owner
or
operator
may
not
make
a
physical
change
in
or
change
in
the
method
of
operation
of
the
Clean
Unit
that
causes
the
emissions
unit
to
function
in
a
manner
that
is
inconsistent
with
the
physical
or
operational
characteristics
that
formed
the
basis
for
the
LAER
determination
(
e.
g.,
possibly
the
emissions
unit's
capacity
or
throughput).

(
b)
The
Clean
Unit
may
not
emit
above
a
level
that
has
been
offset.

(
ii)
The
Clean
Unit
must
comply
with
any
terms
and
128
conditions
in
the
title
V
permit
related
to
the
unit's
Clean
Unit
designation.

(
iii)
The
Clean
Unit
must
continue
to
control
emissions
using
the
specific
air
pollution
control
technology
that
was
the
basis
for
its
Clean
Unit
designation.
If
the
emissions
unit
or
control
technology
is
replaced,
then
the
Clean
Unit
designation
ends.

8.
Offsets
and
netting
at
Clean
Units.
Emissions
changes
that
occur
at
a
Clean
Unit
must
not
be
included
in
calculating
a
significant
net
emissions
increase
(
that
is,

must
not
be
used
in
a
"
netting
analysis"),
or
be
used
for
generating
offsets
unless
such
use
occurs
before
the
effective
date
of
the
Clean
Unit
designation,
or
after
the
Clean
Unit
designation
expires;
or,
unless
the
emissions
unit
reduces
emissions
below
the
level
that
qualified
the
unit
as
a
Clean
Unit.
However,
if
the
Clean
Unit
reduces
emissions
below
the
level
that
qualified
the
unit
as
a
Clean
Unit,
then,
the
owner
or
operator
may
generate
a
credit
for
the
difference
between
the
level
that
qualified
the
unit
as
a
Clean
Unit
and
the
new
emission
limitation
if
such
reductions
are
surplus,
quantifiable,
and
permanent.
For
purposes
of
generating
offsets,
the
reductions
must
also
be
federally
enforceable.
For
purposes
of
determining
creditable
net
emissions
increases
and
decreases,
the
reductions
must
also
be
enforceable
as
a
practical
matter.

9.
Effect
of
redesignation
on
the
Clean
Unit
129
designation.
The
Clean
Unit
designation
of
an
emissions
unit
is
not
affected
by
redesignation
of
the
attainment
status
of
the
area
in
which
it
is
located.
That
is,
if
a
Clean
Unit
is
located
in
an
attainment
area
and
the
area
is
redesignated
to
nonattainment,
its
Clean
Unit
designation
is
not
affected.
Similarly,
redesignation
from
nonattainment
to
attainment
does
not
affect
the
Clean
Unit
designation.

However,
if
an
existing
Clean
Unit
designation
expires,
it
must
re­
qualify
under
the
requirements
that
are
currently
applicable
in
the
area.

J.
Clean
Unit

The
owner
or
operator
of
a
major
stationary
source
has
the
option
of
using
the
Clean
Unit
Test
to
determine
whether
emissions
increases
at
a
Clean
Unit
are
part
of
a
project
that
is
a

required).

(
b)
The
owner
or
operator
made
an
investment
to
install
the
control
technology.
For
the
purpose
of
this
determination,
an
investment
includes
expenses
to
research
the
application
of
a
pollution
prevention
technique
to
the
emissions
unit
or
to
retool
the
unit
to
apply
a
pollution
prevention
technique.
133
(
ii)
Impact
of
emissions
from
the
unit.
The
reviewing
authority
must
determine
that
the
allowable
emissions
from
the
emissions
unit
will
not
cause
or
contribute
to
a
violation
of
any
national
ambient
air
quality
standard
or
PSD
increment,
or
adversely
impact
an
air
quality
related
value
(
such
as
visibility)
that
has
been
identified
for
a
Federal
Class
I
area
by
a
Federal
Land
Manager
and
for
which
information
is
available
to
the
general
public.

(
iii)
Date
of
installation.
An
emissions
unit
may
qualify
as
a
Clean
Unit
even
if
the
control
technology,
on
which
the
Clean
Unit
designation
is
based,
was
installed
before
the
effective
date
of
the
requirements
of
this
paragraph
IV.
J.
3.
in
the
area
where
the
unit
is
located
but
no
sooner
than
June
15,
2004.
However,
for
such
emissions
units,
the
owner
or
operator
must
apply
for
the
Clean
Unit
designation
by
June
15,
2006.
For
technologies
installed
after
June
15,
2004,
the
owner
or
operator
must
apply
for
the
Clean
Unit
designation
at
the
time
the
control
technology
is
installed.

(
iv)
Re­
qualifying
as
a
Clean
Unit.
The
emissions
unit
must
obtain
a
new
permit
(
pursuant
to
requirements
in
paragraphs
IV.
J.
7
and
8
of
this
Ruling)
that
demonstrates
that
the
emissions
unit's
control
technology
is
achieving
a
level
of
emission
control
comparable
to
current­
day
LAER,

and
the
emissions
unit
must
meet
the
requirements
in
paragraphs
IV.
J.

Demonstrating
control
effectiveness
comparable
to
LAER.
The
owner
or
operator
may
demonstrate
that
the
emissions
unit's
control
technology
is
comparable
to
LAER
for
purposes
of
paragraph
IV.
J.
3(
i)
of
this
Ruling
according
to
either
paragraph
IV.
J.
4(
i)
or
(
ii)
of
this
Ruling.

Paragraph
IV.
J.
4(
iii)
of
this
Ruling
specifies
the
time
for
making
this
comparison.

(
i)
Comparison
to
previous
LAER
determinations.
The
Administrator
maintains
an
on­
line
data
base
of
previous
determinations
of
RACT,
BACT,
and
LAER
in
the
RACT/
BACT/
LAER
Clearinghouse
(
RBLC).
The
emissions
unit's
control
technology
is
presumed
to
be
comparable
to
LAER
if
it
achieves
an
emission
limitation
that
is
at
least
as
stringent
as
any
one
of
the
five
best­
performing
similar
sources
for
which
a
LAER
determination
has
been
made
within
the
preceding
5
years,
and
for
which
information
has
been
entered
into
the
RBLC.
The
reviewing
authority
shall
also
compare
this
presumption
to
any
additional
LAER
determinations
of
which
it
is
aware,
and
shall
consider
any
information
on
achieved­
in­
practice
pollution
control
technologies
provided
during
the
public
comment
period,
to
determine
whether
any
presumptive
determination
that
the
control
technology
is
comparable
to
LAER
is
correct.

(
ii)
The
substantially­
as­
effective
test.
The
owner
or
operator
may
demonstrate
that
the
emissions
unit's
control
technology
is
substantially
as
effective
as
LAER.
135
In
addition,
any
other
person
may
present
evidence
related
to
whether
the
control
technology
is
substantially
as
effective
as
LAER
during
the
public
participation
process
required
under
paragraph
IV.
J.
7
of
this
Ruling.
The
reviewing
authority
shall
consider
such
evidence
on
a
caseby
case
basis
and
determine
whether
the
emissions
unit's
air
pollution
control
technology
is
substantially
as
effective
as
LAER.

(
iii)
Time
of
comparison.

(
a)
Emissions
units
with
control
technologies
that
are
installed
before
effective
date
of
requirements
in
this
paragraph.
The
owner
or
operator
of
an
emissions
unit
whose
control
technology
is
installed
before
the
effective
date
of
the
requirements
of
this
paragraph
K.
4.(
iii)(
a)
in
the
area
where
the
unit
is
located,
but
no
later
than
June
15,
2004
may,
at
its
option,
either
demonstrate
that
the
emission
limitation
achieved
by
the
emissions
unit's
control
technology
is
comparable
to
the
LAER
requirements
that
applied
at
the
time
the
control
technology
was
installed,
or
demonstrate
that
the
emission
limitation
achieved
by
the
emissions
unit's
control
technology
is
comparable
to
current­
day
LAER
requirements.
The
expiration
date
of
the
Clean
Unit
designation
will
depend
on
which
option
the
owner
or
operator
uses,
as
specified
in
paragraph
IV.
J.
6
of
this
Ruling.

(
b)
Emissions
units
with
control
technologies
that
are
136
installed
after
June
15,
2004.
The
owner
or

must
demonstrate
that
the
emission
limitation
achieved
by
the
emissions
unit's
control
technology
is
comparable
to
current­
day
LAER
requirements.

5.
Effective
date
of
the
Clean
Unit
designation.
The
effective
date
of
an
emissions
unit's
Clean
Unit
designation
(
that
is,
the
date
on
which
the
owner
or
operator
may
begin
to
use
the
Clean
Unit
Test
to
determine
whether
a
project
involving
the
emissions
unit
is
a
major
modification)
is
the
date
that
the
permit
required
by
paragraph
IV.
J.
7
of
this
Ruling
is
issued
or
the
date
that
the
emissions
unit's
air
pollution
control
technology
is
placed
into
service,

whichever
is
later.

6.
Clean
Unit
expiration.
If
the
owner
or
operator
demonstrates
that
the
emission
limitation
achieved
by
the
emissions
unit's
control
technology
is
comparable
to
the
LAER
requirements
that
applied
at
the
time
the
control
technology
was
installed,
then
the
Clean
Unit
designation
expires
10
years
from
the
date
that
the
control
technology
was
installed.
For
all
other
emissions
units,
the
Clean
Unit
designation
expires
10
years
from
the
effective
date
of
the
Clean
Unit
designation,
as
determined
according
to
paragraph
IV.
J.
5
of
this
Ruling.
In
addition,
for
all
emissions
units,
the
Clean
Unit
designation
expires
any
time
the
owner
or
operator
fails
to
comply
with
the
provisions
for
maintaining
the
Clean
Unit
designation
in
paragraph
137
IV.
J.
9
of
this
Ruling.

7.
Procedures
for
designating
emissions
units
as
Clean
Units.
The
reviewing
authority
shall
designate
an
emissions
unit
a
Clean
Unit
only
by
issuing
a
permit
through
a
permitting
program
that
has
been
approved
by
the
Administrator
and
that
conforms
with
the
requirements
of
§
§
51.160
through
51.164
of
this
chapter
including
requirements
for
public
notice
of
the
proposed
Clean
Unit
designation
and
opportunity
for
public
comment.
Such
permit
must
also
meet
the
requirements
in
paragraph
IV.
J.
8.

8.
Required
permit
content.
The
permit
required
by
paragraph
IV.
J.
7
of
this
Ruling
shall
include
the
terms
and
conditions
set
forth
in
paragraphs
IV.
J.
8(
i)
through
(
vi)
of
this
Ruling.
Such
terms
and
conditions
shall
be
incorporated
into
the
major
stationary
source's
title
V
permit
in
accordance
with
the
provisions
of
the
applicable
title
V
permit
program
under
part
70
or
part
71
of
this
chapter,
but
no
later
than
when
the
title
V
permit
is
renewed.

(
i)
A
statement
indicating
that
the
emissions
unit
qualifies
as
a
Clean
Unit
and
identifying
the
pollutant(
s)

for
which
this
designation
applies.

(
ii)
The
effective
date
of
the
Clean
Unit
designation.

If
this
date
is
not
known
when
the
reviewing
authority
issues
the
permit
(
e.
g.,
because
the
air
pollution
control
technology
is
not
yet
in
service),
then
the
permit
must
138
describe
the
event
that
will
determine
the
effective
date
(
e.
g.,
the
date
the
control
technology
is
placed
into
service).
Once
the
effective
date
is
known,
then
the
owner
or
operator
must
notify
the
reviewing
authority
of
the
exact
date.
This
specific
effective
date
must
be
added
to
the
source's
title
V
permit
at
the
first
opportunity,
such
as
a
modification,
revision,
reopening,
or
renewal
of
the
title
V
permit
for
any
reason,
whichever
comes
first,
but
in
no
case
later
than
the
next
renewal.

(
iii)
The
expiration
date
of
the
Clean
Unit
designation.
If
this
date
is
not
known
when
the
reviewing
authority
issues
the
permit
(
e.
g.,
because
the
air
pollution
control
technology
is
not
yet
in
service),
then
the
permit
must
describe
the
event
that
will
determine
the
expiration
date
(
e.
g.,
the
date
the
control
technology
is
placed
into
service).
Once
the
expiration
date
is
known,
then
the
owner
or
operator
must
notify
the
reviewing
authority
of
the
exact
date.
The
expiration
date
must
be
added
to
the
source's
title
V
permit
at
the
first
opportunity,
such
as
a
modification,
revision,
reopening,
or
renewal
of
the
title
V
permit
for
any
reason,
whichever
comes
first,
but
in
no
case
later
than
the
next
renewal.

(
iv)
All
emission
limitations
and
work
practice
requirements
adopted
in
conjunction
with
emission
limitations
necessary
to
assure
that
the
control
technology
continues
to
achieve
an
emission
limitation
comparable
to
139
LAER,
and
any
physical
or
operational
characteristics
that
formed
the
basis
for
determining
that
the
emissions
unit's
control
technology
achieves
a
level
of
emissions
control
comparable
to
LAER
(
e.
g.,
possibly
the
emissions
unit's
capacity
or
throughput).

(
v)
Monitoring,
recordkeeping,
and
reporting
requirements
as
necessary
to
demonstrate
that
the
emissions
unit
continues
to
meet
the
criteria
for
maintaining
its
Clean
Unit
designation.
(
See
paragraph
IV.
J.
9
of
this
Ruling.)

(
vi)
Terms
reflecting
the
owner
or
operator's
duties
to
maintain
the
Clean
Unit
designation
and
the
consequences
of
failing
to
do
so,
as
presented
in
paragraph
IV.
J.
9
of
this
Ruling.

9.
Maintaining
Clean
Unit
designation.
To
maintain
Clean
Unit
designation,
the
owner
or
operator
must
conform
to
all
the
restrictions
listed
in
paragraphs
IV.
J.
9(
i)

through
(
v)
of
this
Ruling.
This
paragraph
IV.
J.
9
applies
independently
to
each
pollutant
for
which
the
reviewing
authority
has
designated
the
emissions
unit
a
Clean
Unit.

That
is,
failing
to
conform
to
the
restrictions
for
one
pollutant
affects
the
Clean
Unit
designation
only
for
that
pollutant.

(
i)
The
Clean
Unit
must
comply
with
the
emission
limitation(
s)
and/
or
work
practice
requirements
adopted
to
ensure
that
the
control
technology
continues
to
achieve
140
emission
control
comparable
to
LAER.

(
ii)
The
owner
or
operator
may
not
make
a
physical
change
in
or
change
in
the
method
of
operation
of
the
Clean
Unit
that
causes
the
emissions
unit
to
function
in
a
manner
that
is
inconsistent
with
the
physical
or
operational
characteristics
that
formed
the
basis
for
the
determination
that
the
control
technology
is
achieving
a
level
of
emission
control
that
is
comparable
to
LAER
(
e.
g.,
possibly
the
emissions
unit's
capacity
or
throughput).

(
iii)
The
Clean
Unit
may
not
emit
above
a
level
that
has
been
offset.

(
iv)
The
Clean
Unit
must
comply
with
any
terms
and
conditions
in
the
title
V
permit
related
to
the
unit's
Clean
Unit
designation.

(
v)
The
Clean
Unit
must
continue
to
control
emissions
using
the
specific
air
pollution
control
technology
that
was
the
basis
for
its
Clean
Unit
designation.
If
the
emissions
unit
or
control
technology
is
replaced,
then
the
Clean
Unit
designation
ends.

10.
Offsets
and
Netting
at
Clean
Units.
Emissions
changes
that
occur
at
a
Clean
Unit
must
not
be
included
in
calculating
a
significant
net
emissions
increase
(
that
is,

must
not
be
used
in
a
"
netting
analysis"),
or
be
used
for
generating
offsets
unless
such
use
occurs
before
June15,

2004
or
after
the
Clean
Unit
designation
expires;
or,
unless
the
emissions
unit
reduces
emissions
below
the
level
that
141
qualified
the
unit
as
a
Clean
Unit.
However,
if
the
Clean
Unit
reduces
emissions
below
the
level
that
qualified
the
unit
as
a
Clean
Unit,
then
the
owner
or
operator
may
generate
a
credit
for
the
difference
between
the
level
that
qualified
the
unit
as
a
Clean
Unit
and
the
emissions
unit's
new
emission
limitation
if
such
reductions
are
surplus,

quantifiable,
and
permanent.
For
purposes
of
generating
offsets,
the
reductions
must
also
be
federally
enforceable.

For
purposes
of
determining
creditable
net
emissions
increases
and
decreases,
the
reductions
must
also
be
enforceable
as
a
practical
matter.

11.
Effect
of
redesignation
on
the
Clean
Unit
designation.
The
Clean
Unit
designation
of
an
emissions
unit
is
not
affected
by
redesignation
of
the
attainment
status
of
the
area
in
which
it
is
located.
That
is,
if
a
Clean
Unit
is
located
in
an
attainment
area
and
the
area
is
redesignated
to
nonattainment,
its
Clean
Unit
designation
is
not
affected.
Similarly,
redesignation
from
nonattainment
to
attainment
does
not
affect
the
Clean
Unit
designation.

However,
if
a
Clean
Unit's
designation
expires
or
is
lost
pursuant
to
paragraphs
IV.
I.
2(
iii)
and
IV.

Environmentally
beneficial
analysis.
The
environmental
benefit
from
the

used
shall
be
presumed
to

further
reduces
emissions
after
qualifying
for
the
PCP
exclusion
(
e.
g.,
taking
an
operational
restriction
on
the
hours
of
operation).
The
owner
or
operator
may
generate
a
credit
for
the
difference
between
the
level
of
reduction
which
was
used
to
qualify
for
the

(
a)
The
PAL
shall
impose
an
annual
emission
limitation
in
tons
per
year,
that
is
enforceable
as
a
practical
matter,

for
the
entire
major
stationary
source.
For
each
month
during

after
the
first
12
months
of
establishing
a
PAL,
the
major
stationary
source
owner
or
operator
shall
show
that
the
sum
of
the
monthly
emissions
from
each
emissions
unit
under
the

months
is
less
than
the
PAL
(
a
12­
month
average,

rolled
monthly).
For
each
month
during
the
first
11
months
from
the
PAL
effective
date,
the
major
stationary
source
owner
or
operator
shall
show
that
the
sum
of
the
preceding
monthly
emissions
from
the
PAL
effective
date
for
each
emissions
unit
under
the
PAL
is
less
than
the
PAL.

(
b)
The
PAL
shall
be
established
in
a
PAL
permit
that
meets
the
public
participation
requirements
in
paragraph

quantifiable,
from
all
emissions
units
that
emit
or
have
the
potential
to
emit
the
PAL
pollutant
at
the
major
stationary
source.

(
e)
Each
PAL
shall
regulate
emissions
of
only
one
pollutant.

(
f)
Each
PAL
shall
have
a
PAL
effective
period
of
10

(
ii)
At
no
time
(
during
or
after
the
PAL
effective
period)
are
emissions
reductions
of
a
PAL
pollutant,
which
occur
during
the
PAL
effective
period,
creditable
as
decreases
for
purposes
of
offsets
under
paragraph
IV.
C
of
this
Ruling
unless
the
level
of
the
PAL
is
reduced
by
the

6.
Setting
the
10­
year
actuals
PAL
level.
The
actuals
PAL
level
for
a
major
stationary
source
shall
be
established
as
the
sum
of
the
baseline
actual
emissions
(
as
defined
in
paragraph
II.
A.
32
of
this
Ruling)
of
the
PAL
pollutant
for
154
each
emissions
unit
at
the
source;
plus
an
amount
equal
to
the
applicable
significant
level
for
the
PAL
pollutant
under
paragraph
II.
A.
10
of
this
Ruling
or
under
the
Act,
whichever

lower.
When
establishing
the
actuals
PAL
level,
for
a
PAL
pollutant,
only
one
consecutive
24­
month
period
must
be
used
to
determine
the
baseline
actual
emissions
for
all
existing
emissions
units.
However,
a
different
consecutive
24­
month
period
may
be
used
for
each
different
PAL
pollutant.
Emissions
associated
with
units
that
were
permanently
shutdown
after
this
24­
month
period
must
be
subtracted
from
the
PAL
level.
Emissions
from
units
on
which
actual
construction
began
after
the
24­
month
period
must
be
added
to
the
PAL
level
in
an
amount
equal
to
the
potential
to
emit
of
the
units.
The
reviewing
authority
shall
specify
a
reduced
PAL
level(
s)
(
in
tons/
yr)
in
the
PAL
permit
to
become
effective
on
the
future
compliance
date(
s)

of
any
applicable
Federal
or
State
regulatory
requirement(
s)

that
the
reviewing
authority
is
aware
of
prior
to
issuance
of
the
PAL
permit.
For
instance,
if
the
source
owner
or
operator
will
be
required
to
reduce
emissions
from
industrial
boilers
in
half
from
baseline
emissions
of
60
ppm
NOx
to
a
new
rule
limit
of
30
ppm,
then
the
permit
shall
contain
a
future
effective
PAL
level
that
is
equal
to
the
current
PAL
level
reduced
by
half
of
the
original
baseline
emissions
of
such
unit(

stationary
source
is
less
than
the
PAL,
the
reviewing
authority
shall
adjust
the
PAL
to
a
level
no
greater
than
the
potential
to
emit
of
the
source;
and
(

The
reviewing
authority
shall
not
approve
a
renewed
PAL
level
higher
than
the
current
PAL,
unless
the
major
stationary
source
has
complied
with
the
provisions
of
paragraph

If
the
compliance
date
for
a
State
or
Federal
requirement
that
applies
to
the
PAL
source
occurs
during
the
PAL
effective
period,
and
if
the
reviewing
authority
has
not
already
adjusted
for
such
requirement,
the
PAL
shall
be
adjusted
at
the
time
of

permit
renewal,
whichever
occurs
first.

11.
Increasing
a
PAL
during
the
PAL
effective
period.

(
i)
The
reviewing
authority
may
increase
a
PAL
emission
limitation
only
if
the
major
stationary
source
complies
with
the
provisions
in
paragraphs
IV.
L.
11(
i)(
a)

through
(
d)
of
this
Ruling.

(
a)
The
owner
or
operator
of
the
major
stationary
source
shall
submit
a
complete
application
to
request
an
increase
in
the
PAL
limit
for
a
PAL
major
modification.

Such
application
shall
identify
the
emissions
unit(
s)

contributing
to
the
increase
in
emissions
so
as
to
cause
the
major
stationary
source's
emissions
to
equal
or
exceed
its
PAL.
163
(
b)
As
part
of
this
application,
the
major
stationary
source
owner
or
operator
shall
demonstrate
that
the
sum
of
the
baseline
actual
emissions
of
the
small
emissions
units,

plus
the
sum
of
the
baseline
actual
emissions
of
the
significant
and
major
emissions
units
assuming
application
of
BACT
equivalent
controls,
plus
the
sum
of
the
allowable
emissions
of
the
new
or
modified
emissions
unit(
s)
exceeds
the
PAL.
The
level
of
control
that
would
result
from
BACT
equivalent
controls
on
each
significant
or
major
emissions
unit
shall
be
determined
by
conducting
a
new
BACT
analysis
at
the
time
the
application
is
submitted,
unless
the
emissions
unit
is
currently
required
to
comply
with
a
BACT
or
LAER
requirement
that
was
established
within
the
preceding
10
years.
In
such
a
case,
the
assumed
control
level
for
that
emissions
unit
shall
be
equal
to
the
level
of
BACT
or
LAER
with
which
that
emissions
unit
must
currently
comply.

(
c)
The
owner
or
operator
obtains
a
major
NSR
permit
for
all
emissions
unit(
s)
identified
in
paragraph
IV.
L.
11(
i)(
a)
of
this
Ruling,
regardless
of
the
magnitude
of
the
emissions
increase
resulting
from
them
(
that
is,
no
significant
levels
apply).
These
emissions
unit(
s)
shall
comply
with
any
emissions
requirements
resulting
from
the
nonattainment
major
NSR
program
process
(
for
example,
LAER),

even
though
they
have
also
become
subject
to
the
PAL
or
continue
to
be
subject
to
the
PAL.
164
(
d)
The
PAL
permit
shall
require
that
the
increased
PAL
level
shall
be
effective
on
the
day
any
emissions
unit
that
is
part
of
the
PAL
major
modification
becomes
operational
and
begins
to
emit
the
PAL
pollutant.

(
ii)
The
reviewing
authority
shall
calculate
the
new
PAL
as
the
sum
of
the
allowable
emissions
for
each
modified
or
new
emissions
unit,
plus
the
sum
of
the
baseline
actual
emissions
of
the
significant
and
major
emissions
units
(
assuming
application
of
BACT
equivalent
controls
as
determined
in
accordance
with
paragraph
IV.
L.
11(
i)(
b)),
plus
the
sum
of
the
baseline
actual
emissions
of
the
small
emissions
units.

(
iii)
The
PAL
permit
shall
be
revised
to
reflect
the
increased
PAL
level
pursuant
to
the
public
notice
requirements
of
paragraph
IV.
L.
5
of
this
Ruling.

for
PALs.

(
i)
General
Requirements.

(
a)
Each
PAL
permit
must
contain
enforceable
requirements
for
the
monitoring
system
that
accurately
determines
plantwide
emissions
of
the
PAL
pollutant
in
terms
of
mass
per
unit
of
time.
Any
monitoring
system
authorized
for
use
in
the
PAL
permit
must
be
based
on
sound
science
and
meet
generally
acceptable
scientific
procedures
for
data
quality
and
manipulation.
Additionally,
the
information
generated
by
such
system
must
meet
minimum
legal
requirements
for
admissibility
in
a
judicial
proceeding
to
165
enforce
the
PAL
permit.

(
b)
The
PAL
monitoring
system
must
employ
one
or
more
of
the
four
general
monitoring
approaches
meeting
the
minimum
requirements
set
forth
in
paragraphs
IV.
L.
12(

for
any
national
ambient
air
quality
standard,

the
restrictions
in
paragraphs
(
a)
and
(

of
this
section
shall
apply
to
any
major
stationary
source
or
major

that
would
be
major
for
the
pollutant
(
or
precursors,
where
applicable)
for
which
the
area
is
designated
nonattainment
or
a
transport
region,
if
the
stationary
source
or
major
modification
would
be
constructed
anywhere
in

designated
nonattainment
area
or

region.
A
major
stationary
source
or
major
modification
that
is
major
for
volatile
organic
compounds
is
also
major
for
ozone.
A
major
stationary

At
such
time
that
a
particular
source
or
modification
becomes
a
major
stationary

solely
by
virtue
of
a
relaxation
in
any

which
was
established
after
August
7,

1980,
on
the
capacity
of
the
source
or
modification
otherwise
to
emit
a
pollutant,
such
as
a
restriction
on
hours
of
operation,
then:

(
1)
If
the
construction
moratorium
imposed
pursuant
to
this
section
is
still
in
effect
for
the
nonattainment
area
178
or
transport
region
in
which
the
source
or
modification
is
located,
then
the
permit
may
not
be
so
revised;
or
(
2)
If
the
construction
moratorium
is
no
longer
in
effect
in
that
area,
then
the
requirements
of
§
51.165
of
this
chapter
shall
apply
to
the
source
or
modification
as
though
construction
had
not
yet
commenced
on
the
source
or
modification.

does
not
apply
to
major
stationary
sources
or
major
modifications
locating
in
a
clearly
defined
part
of
a
nonattainment
area
or
transport
region
(
such
as
a
political
subdivision
of
a
State),
where
the
EPA
finds
that
a
plan
which
meets
the
requirements
of
part
D
of
title
I
of
the

is
in

and
is
being
