6.4.1.1
Birmingham
Area
MSA
The
following
is
the
9
factor
analysis
for
Birmingham
MSA
and
surrounding
Counties.
Alabama's
submittal
in
February
2004,
recommended
Jefferson
County
be
designated
nonattainment
for
the
fine
particulate
matter
(
PM2.5),
based
on
2001
­
2003
monitoring
data.
Based
on
the
following
analysis
EPA
believes
that
Jefferson,
Shelby
and
Walker
Counties
should
be
included
in
the
PM2.5
nonattainment
area.
Jefferson
County
has
a
violating
monitor
and
the
State
recommended
it
as
nonattainment.
Shelby
County
is
within
the
MSA,
has
high
PM,
SOx,
NOx,
and
VOC
emissions,
approximately
52
percent
of
its
commuters
commute
to
Jefferson
County,
has
relatively
high
population
and
VMT,
and
has
a
power
plant
within
the
County.
Walker
County
has
high
SOx
and
NOx
emissions
from
a
power
plant.
We
have
included
in
our
recommended
nonattainment
area
Walker
County
that
is
contiguous
to
the
MSA
with
a
violating
monitor,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
or
facilities
(
e.
g.,
power
plants)
which
we
believe
contributes
to
the
nearby
nonattainment
problem.
We
have
included
this
County
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
County,
including
such
large
facilities,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
Walker
County,
encompassing
the
large
facility
or
facilities,
should
be
designated
nonattainment.
Based
on
the
following
analysis,
EPA
agrees
that
Blount,
St.
Clair,
Calhoun,
Talladega,
Tuscaloosa
and
Morgan
Counties
should
be
recommended
attainment/
unclassifiable
for
PM2.5.
Blount
County
has
no
major
sources,
has
relative
low
emissions
and
has
the
lowest
population
and
VMT
in
the
Birmingham
area.
St.
Clair
County
has
relatively
low
SOx
and
PM
emissions
and
has
a
small
population.
Calhoun
County
has
no
major
sources,
84
percent
of
its
commuters
commute
within
its
County
and
it
is
adjacent
to
the
MSA.
Talladega
County
has
a
small
population,
an
attaining
monitor
(
14.7
DV),
low
VMT
and
it
is
adjacent
to
the
MSA.
Tuscaloosa
County
has
no
major
sources,
89
percent
of
its
commuters
commute
within
its
County,
has
an
attaining
monitor
(
11.6
DV)
and
it
is
adjacent
to
the
MSA.
Morgan
County
has
an
attaining
monitor,
is
part
of
another
MSA,
72
percent
of
its
commuters
commute
within
its
County
and
is
several
Counties
away
from
Jefferson
County.

counties
all
have

Morgan

monitoring
site
(

began
operating
in

1999,
and
was
terminated
in

A

was
selected
in
the
Decatur
area
and
monitoring
begain
in
August
2001.
The
State
of
Alabama
requested
and
received
Region
4
concurrence
for
these
network
design
changes.
The
changes
were
approved
due
to
a
local
diesel
source
impacting
the
initial
monitoring
site.
The
data
from
the
initial
monitoring
site
was
left
in
the
Air

database
and
is
in

Data
sets
from
each
of

sites
are
incomplete
when
considered
individually.
When
the

demonstrate
the

to
be
below

Justifications
for
Changes
to

Recommendations
Contained
in
the
June

2004
Letters
to
States
Walker
County,
AL:

In
the
June
29,
2004,
letters
from
EPA
to
the
States
responding
to
their
designation
recommendations,
EPA
recommended
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
in
the
nonattainment
area.
Walker
County,
AL
is
one
of
those
counties.
Walker
County
has
low
population
(
70,655
compared
to
661,153
in
Jefferson
County
where
the
city
of
Birmingham
is
located),
low

(
851,000
compared
to
8,242,000
in
Jefferson
County
),
and
the
only
large
point
source
is
the
Gorgas
Steam
Plant.

A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.
The
State
of
Alabama
subsequently
submitted
two
partial
county
recommendations,
one
included
the
Gorgas
Steam
Plant
boundary
as
a
noncontiguous
area
and
the
other
was
contiguous
to
the
Birmingham
area.

After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifiers
(

portion
of
Walker
County
as
part
of
the
Birmingham
nonattainment
area.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
counties
as
nonattainment
for
the
Birmingham,
AL
area:
Jefferson,
Shelby,
and
Walker
(
Partial).

6.4.1.2
Columbus
Area
MSA
The
following
is
the
9
factor
analysis
for
Columbus
MSA
and
surrounding
Counties.
Alabama's
submittal
in
February
2004,
recommended
that
Russell
County
be
designated
nonattainment
for
the
fine
particulate
matter
(
PM2.5),
based
on
2001
­
2003
monitoring
data.
Georgia's
submittal
in
June
2004,
recommended
that
Harris,
Muscogee
and
Chattahoochee
Counties
be
designated
attainment
for
PM2.5.
Based
on
the
following
analysis
EPA
recommends
that
Lee
and
Russell
counties
in
Alabama,
and
Harris,
and
Muscogee
Counties
in
Georgia,
should
be
included
in
the
PM2.5
nonattainment
area.
Lee
County
is
adjacent
to
the
MSA,
has
high
VMT
and
a
large
population.
Russell
County
has
a
violating
monitor
and
the
State
recommended
it
as
nonattainment.
Harris
County
has
relatively
high
NOx
and
VOC
emissions
and
relatively
high
VMT.
Muscogee
County
has
high
NOx
and
VOC
emissions,
high
VMT
and
a
large
population.
Based
on
the
following
analysis,
EPA
agrees
with
the
recommendation
that
Barbour,
Chambers,
Montgomery,
Elmore
and
Tallapoosa
Counties
in
Alabama,
and
Chattahoochee,
Troup,
Stewart,
Meriwether,
Sumter
Counties
in
Georgia,
should
be
attainment/
unclassifiable
for
PM2.5
based
on
low
emissions,
low
VMT
and
low
population.

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
EPA's
initial
nonattainment
recommendations
on
June
29,
2004,
included
the
Lee
County,
Alabama,
and
Harris
County,
Georgia,
as
part
of
the
Columbus,
GA
nonattainment
area.
Upon
further
review
of
additional
information
provided
by
the
states,
EPA
is
revising
its
recommendation
and
is
designating
Lee
County,
AL
and
Harris
County,
GA
as
attainment/
unclassifiable.

Lee
County,
AL:

Lee
County,
Alabama,
is
being
designated
attainment/
unclassifiable
because
it
has
no
major
point
sources
of
precursor
emissions
with
40%
(
7,474
tons)
of
its
total
VOC
and
87%
(
5,125
tons)
of
its
total
NOx
emissions
coming
from
mobile
sources.
Lee
County
is
adjacent
to
the
MSA.
The
majority
of
the
commuting
population
remains
inside
Lee
County,
with
only
5
percent
commuting
to
Russell
County
where
the
violating
monitor
is
located.

We
considered
the
data
in
the
request
for
spatial
averaging
for
the
Columbus
area,
which
was
denied,
while
evaluating
the
other
factors
and
determined
that
Lee
County
is
not
contributing
to
the
violations.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
county
as
nonattainment
for
the
Columbus,
GA­
AL
area:
Russell.

6.4.1.3
Chattanooga
Area
The
Chattanooga
MSA
contains
the
following
Tennessee
counties:
Marion
and
Hamilton;
and
the
following
Georgia
Counties:
Dade,
Walker,
and
Catoosa.
Based
on
air
quality
data
for
2001­
2003,
the
monitor
with
the
highest
design
value
in
Hamilton
County
has
a
design
value
of
16.1
and
the
monitor
in
Walker
County
has
a
design
value
of
15.6.
No
other
counties
in
the
MSA
contain
ambient
air
monitors.
The
State
of
Tennessee
recommended
as
nonattainment
the
county
of
Hamilton
and
the
State
of
Georgia
recommended
as
nonattainment
the
county
of
Walker.
The
States
have
recommended
that
all
other
counties
be
designated
attainment.
The
State
of
Tennessee
submitted
some
justification
for
this
recommendation,
however,
they
indicated
that
the
detailed
emission
information
would
be
provided
at
a

EPA
is
modifying
the
State
6­
150
of
Tennessee's
recommendation
and
will
review
the
additional
information
during
the
120
day
period
following
the
notification
letter.

EPA
has
received
some
information
from
the
State
of
Tennessee
that
Marion
(
MSA)
County
should
be
designated
attainment
for
the
PM2.5
standard
and
no
justification
from
the
State
of
Georgia
indicating
that
any
other
counties
should
be
included
or
excluded
from
the
Chattanooga
PM2.5
nonattainment
area.
Adjacent
counties
with
significant
emissions
include
McMinn
and
Roane
Counties
which
are
attached
to
the
Knoxville
nonattainment
area
and
Floyd
County
which
is
a
separate
nonattainment
area.

Additionally
we
have
included
in
our
recommended
nonattainment
area
Jackson
County,
AL,
that
is
adjacent
to
the
Chattanooga
MSA,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
or
facilities
(
e.
g.,
power
plants)
which
we
believe
contribute
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
county,
including
such
large
facilities,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
this
adjacent
county,
encompassing
the
large
facility
or
facilities,
should
be
designated
nonattainment.
Therefore
EPA
is
modifying
the
States'
recommendations
to
include
all
of
the
counties
in
the
MSA
and
the
adjacent
county
of
Jackson,
Alabama.

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
Jackson
County,
AL:

In
the
June
29,
2004,
letters
from
EPA
to
the
States
responding
to
their
designation
recommendations,
EPA
recommended
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
in
the
nonattainment
area.
Jackson
County,
AL
is
one
of
those
counties.
Jackson
County
has
4,389
tons
of
PM,
4,333
tons
of
SO2
and
31,502
of
NOx
emissions,
with
the
majority
of
emissions
coming
from
the
Widows
Creek
Power
Plant.
The
commuting
patterns
show
that
68%
(
16,642)
of
the
working
population
in
the
county
actually
works
in
Jackson
County
with
8%
(
1,853)
working
in
Madison
County
and
another
8%
(
1,695)
working
in
Dekalb
County.
The
available
data
indicate
that
there
are
no
identifiable
commuting
patterns
between
Jackson
County
and
Chattanooga.

A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.
The
State
of
Alabama
subsequently
submitted
two
partial
county
recommendations,
one
included
the
Widows
Creek
Plant
boundary
as
a
contiguous
area
and
the
other
was
contiguous
to
the
nearest
county
recommended
as
nonattainment.
6­
156
After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifier
(
StateFIPs­
CoFIPs­
Tract#­
Block
Group#)
01­
071­

portion
of

as
described
in

June

letter,
and
review
of

information

analysis,
EPA
is

the
following
county
as
nonattainment
for
the
Chattanooga,

area:
Jackson

Counties
Based
on

alternative,
it
is
EPA's
position
that
DeKalb
and
Etowah
Counties
be
designated
as
unclassifiable.
These
two
counties
had
monitoring
data
for
2000­
2002
that
was
violating
and
have
incomplete
data
for

will
not

which
includes
the
adjacent
county
of
Hall,
plus
a
partial

recommendation
for
Heard
County
adjacent
to
the
Atlanta
MSA
which
contains
no
monitor,
but
a
power
plant
with
large
SO2

NOx
emissions.
The
State
also
recommended
that
Floyd
County
which
is
adjacent
to
the
Atlanta
MSA
and
has
a
violating
monitor
be
designated
as
a
separate
nonattainment

The
adjacent
counties
of
Hall,
Jasper
and
Putnam
have
significant
emissions
with
a
potential
to
contribute
to
the
violations
in
the
Atlanta
area.
Putnam
county
contains
a
power
plant
with
large
SO2
and
NOx
emissions.
We
have
included
in
our
recommended
nonattainment
area
Putnam
County
in
your
state
that
is
contiguous
to
this
CMSA
with
a
violating
monitor,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
or
facilities
(
e.
g.,
power
plants)
which
we
believe
contributes
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
county,
including
such
large
facilities,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
such
contiguous
county,
encompassing
the
large
facility
or
facilities,
should
be
designated
nonattainment.
Based
on
emission
levels

Based
on
the
emissions
analysis
the
adjacent
counties
of
Floyd,
Hall,
Heard,
Jasper,
and
Putnam
have
significant
emissions
indicating
potential
contribution
to
the
violations
in
the
area.
The
Agency
agrees
that
Floyd
can
be
designated
as
a
separate
PM2.5
nonattainment
area
and
with
the
partial
county
recommendation
for
Heard.
The
Agency
also
agrees
with
the
State
that
Pickens
is
not
contributing
based
on
the
low
emissions
levels.
It
was
not
included
in
the
ozone
nonattainment
area
based

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
EPA's
initial
nonattainment
recommendations
on
June
29,2004,
included
Jasper
County
as
part
of
the
Atlanta
nonattainment
area.
Upon
further
review
of
additional
information
provided
by
the
State,
EPA
is
revising
its
recommendation
and
is
designating
Jasper
County
as
attainment/
unclassifiable,
and
a
portion
of
Putnam
County
as
nonattainment.
The
remainder
of
Putnam
County
will
be
designated
attainment/
unclassifiable.

Jasper
County:

Jasper
County
emissions
in
tons
per
year
are:
PM
(
2,835),
NOx
(
28,144),
SO2
(
210),
VOC
(
2,453).
Jasper
County
was
added
to
the
Altanta
metropolitan
area
in
the
2003
OMB
definition,
has
no
monitor,
a
low
population
(
12,283),
and
a
low
population
density
(
33
people/
square
mile),
when
compared
to
the
Atlanta
MSA.
For
example,
Fulton
County,
which
contains
the
design
value
monitor,
has
a
population
of
(
825,431),
and
a
population
density
of
(
1,560
people/
square
mile).
The
county
has
low
emissions
when
compared
to
the
Atlanta
MSA.
The
majority
of
the
emissions
in
Jasper
County
come
from
a
Georgia
Pacific
facility
which
is
45
miles
from
the
nearest
violating
monitor.
Additionally,
Jasper
County
has
a
low
number
of
commuters
(
5,123)
and
only
667
of
those
commuters
commute
to
the
Atlanta
MSA.
The
2002
VMT
(
112,000)
for
Jasper
county
is
lower
than
any
county
in
the
Atlanta
MSA.

Putnam
County:

In
the
June
29,2004,
letters
from
EPA
to
the
State
responding
to
their
designation
recommendations,
EPA
proposed
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
to
include
it
in
the
nonattainment
area.
Putnam
County,
GA
is
one
of
those
counties.

Putnam
County
is
adjacent
to
Jasper
County
which
was
added
to
the
Altanta
metropolitan
area
in
the
2003
OMB
definition,
and
has
no
monitor.
Putnam
County
emissions
in
tons
per
year
and
percent
of
MSA
are:
PM
(
3,726),
SO2
(
65,560),
NOx
(
34,202),
and
VOC
(
1,175).
The
NOx
and
SO2
emissions
are
primarily
from
the
Harlee
Branch
power
plant
which
is
approximately
67
miles
from,
and
downwind
of,
the
nearest
violating
monitor.
Putnam
County
has
a
total
of
(
8,055)
commuters
of
which
only
(
388)
commute
to
the
Atlanta
MSA.
The
2002
VMT
(
179,000)
for
Putnam
County
is
lower
than
any
county
in
the
Atlanta
MSA.

A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
6­
168
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.

After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifier
(
StateFIPs­
CoFIPs­
Tract#­
Block
Group#)
13­
237­
9603­
1
portion
of
Putnam
County
as
part
of
the
Atlanta
nonattainment
area.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
counties
as
nonattainment
for
the
Atlanta,

area:
Barrow,
Bartow,

Macon
Area
MSA
The
Macon
MSA
contains
the
counties
of:
Bibb,
Houston,
Jones,
Peach,
and
Twiggs.

On
February

2004,
the
State
of
Georgia
submitted
to
EPA
their
PM
2.5
nonattainment
recommendations.
Georgia
recommended
only
counties
which
contained
a
monitored
violation
and
provided
no
further
justification.
On
June
17,
2004,
the
State
submitted
additional
information
and
revised
recommendations.
The
revision
recommended
that
Bibb
County
be
nonattainment
and
Monroe
County
as
a

area.
EPA

Based
on
this
analysis,
Monroe
County
has
significant
emissions
which
contribute
to
the
violations
at
the
Bibb
County
monitor.
Although
Jasper
and
Putnam
counties
also
have
significant
emissions,
EPA
believes
those
counties
should
be
included
in
the
Atlanta
nonattainment
area,
rather
than
the
Macon
nonattainment
area.
For
the
counties
in

there
is

break
in

weighted
emission
score
between
Bibb
and
the
remaining

Recommendations
Contained
in
the

29,
2004
Letters
to
States
EPA's
initial
nonattainment
recommendations
on
June
29,2004,
included
the
counties
of
Oconee
and
Madison
as
part
of
the
Athens
nonattainment
area.
Upon
further
review
of
additional
information
provided
by
the
State,
EPA
is
revising
its
recommendation
and
is
designating
Oconee
and
Madison

Oconee
County:

Oconee
County
emissions
in
tons
per
year
and
percent
of
MSA
emissions
are:
SO2
(
111

28%),
NOx
(
1,599/
25%),
PM
(
507/
35%)
and
VOC
(
2,047/

These
emissions
are
low
when
compared
to
Clarke
County
which
has
over
half
of
the
SO2,
NOx,
and
VOC
emissions
for
the

of
(
103,881/
66%)
and
a
high
population
density
(
859

Oconee
County
has
a
low
total
number
of
commuters
(
12,903)
of
which
6,696
commute
to
Clarke
County.
This
is
a
low
number
of
commuters
compared
to
Clarke
County's
(
48,241)
of
which
80
percent
(
39,009)
remain
in
Clarke
County.
Of
the
daily
VMT
in
the
MSA,
55
percent
occurs
in
Clarke
County.
Oconee
County
does
not
contain
a
monitor.

Madison
County:

Madison
County
emissions
in
tons
per
year
and
percent
of
MSA
are:
SO2
(
70/

NOx
(
1,449/
23%),
PM
(
543/

are
low
when
compared
to
Clarke
County
which
has
over
half
of
the

Madison
County
also
has
a
low
population
(
26,717/

and
a
low

Madison
County
has
a
low
total
number
of
commuters
(
12,257)
of
which
6,048
commute
to
Clarke
County.
This
is
a
low
number
of
commuters
compared
to
Clarke

(
48,241)
of
6­
178
which
80

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
county
as
nonattainment
for
the
Athens,
GA
area:
Clarke
6.4.2.4
Chattanooga
Area
The
Chattanooga
MSA
contains
the
following
Tennessee
counties:
Marion
and
Hamilton;
and
the
following
Georgia
Counties:
Dade,
Walker,
and
Catoosa.
Based
on
air
quality
data
for
2001­
2003,
the
monitor
with
the
highest
design
value
in
Hamilton
County
has
a
design
value
of
16.1
and
the
monitor
in
Walker
County
has
a
design
value
of
15.6.
No
other
counties
in
the
MSA
contain
ambient
air
monitors.
The
State
of
Tennessee
recommended
as
nonattainment
the
county
of
Hamilton
and
the
State
of
Georgia
recommended
as
nonattainment
the
county
of
Walker.
The
States
have
recommended
that
all
other
counties
be
designated
attainment.
The
State
of
Tennessee
submitted
some
justification
for
this
recommendation,
however,
they
indicated
that
the
detailed
emission
information
would
be
provided
at
a
later
date.
EPA
is
modifying
the
State
of
Tennessee's
recommendation
and
will
review
the
additional
information
during
the
120
day
period
following
the
notification
letter.

EPA
has
received
some
information
from
the
State
of
Tennessee
that
Marion
(
MSA)
County
should
be
designated
attainment
for
the
PM2.5
standard
and
no
justification
from
the
State
of
Georgia
indicating
that
any
other
counties
should
be
included
or
excluded
from
the
Chattanooga
PM2.5
nonattainment
area.
Adjacent
counties
with
significant
emissions
include
McMinn
and
Roane
Counties
which
are
attached
to
the
Knoxville
nonattainment
area
and
Floyd
County
which
is
a
separate
nonattainment
area.

Additionally
we
have
included
in
our
recommended
nonattainment
area
Jackson
County,
AL,
that
is
adjacent
to
the
Chattanooga
MSA,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
or
facilities
(
e.
g.,
power
plants)
which
we
believe
contribute
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
county,
including
such
large
facilities,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
this
adjacent
county,
encompassing
the
large
facility
or
facilities,
should
be
designated
nonattainment.
Therefore
EPA
is
modifying
the
States'
recommendations
to
include
all
of
the
counties
in
the
MSA
and
the
adjacent
county
of
Jackson,
Alabama.

States
EPA's
initial

Dade
County
as

of
the
Chattanooga
nonattainment

and
designating
Dade
County
as

Dade
County:

Dade
County
emissions
in
tons
per

NOx
(
2,415/

and
VOC
(
1,574/

These
are
the
lowest
emissions
of
any
county
in
the
MSA.
Dade
County
contains
no
major
point

has
the
lowest

EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of

6.4.2.5
Columbus
Area
MSA
The
following
is
the
9
factor
analysis
for
Columbus
MSA
and
surrounding
Counties.
Alabama's
submittal
in
February
2004,
recommended
that
Russell
County
be
designated
nonattainment
for
the
fine
particulate
matter
(
PM2.5),
based
on
2001
­
2003
monitoring
data.
Georgia's
submittal
in
June
2004,
recommended
that
Harris,
Muscogee
and
Chattahoochee
Counties
be
designated
attainment
for
PM2.5.
Based
on
the
following
analysis
EPA
recommends
that
Lee
and
Russell
counties
in
Alabama,
and
Harris,
and
Muscogee
Counties
in
Georgia,
should
be
included
in
the
PM2.5
nonattainment
area.
Lee
County
is
adjacent
to
the
MSA,
has
high
VMT
and
a
large
population.
Russell
County
has
a
violating
monitor
and
the
State
recommended
it
as
nonattainment.
Harris
County
has
relatively
high
NOx
and
VOC
emissions
and
relatively
high
VMT.
Muscogee
County
has
high
NOx
and
VOC
emissions,
high
VMT
and
a
large
population.
Based
on
the
following
analysis,
EPA
agrees
with
the
recommendation
that
Barbour,
Chambers,
Montgomery,
Elmore
and
Tallapoosa
Counties
in
Alabama,
and
Chattahoochee,
Troup,
Stewart,
6­

Justifications
for
Changes
to

Recommendations
Contained
in

June

Letters
to
States
EPA's
initial
nonattainment
recommendations
on
June
29,
2004,
included
the
Counties
of
Lee
in
Alabama
and
Harris
in
Georgia
as
part
of
the
Columbus,
GA
nonattainment
area.
Upon
further
review
of
additional
information
provided
by
the
states,
EPA
is
revising
its
recommendation
and
is
designating
Lee
County,
AL
and
Harris
County,
GA
as
attainment/
unclassifiable.

Harris
County:

Harris
County,
Georgia,
is
being
designated
attainment/
unclassifiable
because
it
has
low
population
in
the
MSA
which
is
only
9%
(
25,092)
as
compared
to
185,948
in
Muscogee
County,
the
most
populated
County.
Only
214
of
Harris
County
commuters
commute
into
Russell
County,
where
the
violating
monitor
is
located,
and
it
has
low
VMT
(
547,000)
as
compared
to
1,594,000
in
Muscogee.
Harris
County
has
no
major
point
sources
of
precursor
emissions
and
comparatively
low
emissions
of
590
tons
of
PM,
104
tons
of
SO2,
and
2,856
tons
of
NOx.

We
considered
the
data
in
the
request
for
spatial
averaging
for
the
Columbus
area,
which
was
denied,
while
evaluating
the
other
factors
and
determined
that
Harris
County
is
not
contributing
to
the
violations.

On
February

the

their
PM

nonattainment
recommendations.
Georgia
recommended
only
counties
which
contained
a

and
provided
no
further
justification.
On
June
15,
2004,
the
State
submitted
additional
information
and
revised
recommendations
for
the
Augusta
area.
The
revision
recommended
that
Richmond
County
be
unclassifiable.

Richmond
County
has
two
PM2.5
monitors
with
air
quality
data
for
2001­
2003.
The
data
for
one
monitor
demonstrates
attainment
and
the
other
monitor
has
incomplete
data
for
2001­
2003
that
was
violating.
EPA's
analysis
of
all
the
available
monitoring
data
indicates
that
the
area
should
be
designated
as
attainment/
unclassifiable.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,

letter,
and
review
of
additional

attainment/
classifiable
for
the
PM2.5
standard,
although
they
have
significant
emissions
due
to
power
plants.
These
counties
have
relatively
low
populations,
low
population
growth,
and
low
VMT
.
Further,
their
commuting
patterns
and
distance
from
the
violating
monitors
indicate
that
these
counties
do
not
contribute
to
the
violations
in
the
area.
The
other
adjacent
counties
do
not
contribute
and
therefore,
will
be
designated
as
attainment/
unclassifiable.

Based
on
the
analysis
for
this
factor
for
Kentucky
only,
Boone,

Based
on
the
analysis
for
this
factor,
the
populations
for
the
Kentucky
counties
are
much
smaller
than
those
in
the
Ohio
Counties
of
Hamilton,
Butler,
and
Montgomery.
The
Kentucky
Counties
of
Boone,
Kenton,
and
Campbell
have
population
values
of
some
significance
as
compared
to
the
much
smaller
MSA
Kentucky
Counties
of

A
notable
number
of
commuters
from
Kenton
and
Campbell
Counties
commute
into
violating
Hamilton
County.
Although
these
numbers
are
far
less
than
the
number
of
commuters
in
Hamilton
County,
in
conjunction
with
VMT
data
analyzed
below,
they
indicate
some
potential
for
contributing
to
the
mobile
source
emissions
in
the
area.

Although
47%
of
Boone's
44,507
workers
commute
into
other
counties
in
the
MSA,
a
relatively
small
number
commute
into
the
violating
counties.
In
Carroll
County,
78%
of
the
4,466
workers
commute
within
the
County.
Similarly,
in
Mason
County,
79%
of
the
7,560
workers
commute
within
the
County.
Thus,
onroad
mobile
source
emissions
from
commuting
patterns
for
Boone,
Carroll,
and
Mason
Counties
do
not
appear
to
be
contributing
to
violations
in
the
area.
This
factor
is
not
significant
for
the
remaining
Kentucky
counties
listed

have
the
highest
population
growth
rates
from

only
Boone
County's

(
third
highest

is
significant
enough
to
indicate
a

contribute
to
violations
in
the
area.
The
population
growth
rates
of
Carroll

thus,
do
not

Based
on
an
analysis
of
this

the
information
provided
is
not
sufficient
to
provide
a
compelling
argument
to
exclude

Based
on
an
analysis
of
this
factor,
there
are
no
significant
topographical
issues
associated
with
this
MSA.
For
the
adjacent
Carroll

Counties
in
Kentucky
with
significant

both
counties
are
two
counties

6.4.3.2
Louisville
Area
The
Louisville
MSA
contains
the
Kentucky
Counties
of
Jefferson,
Bullitt,
and
Oldham;
and
the
Indiana
Counties
of
Floyd,
Clark,
Harrison,
and
Scott.
Jefferson
County,
Kentucky
and
Clark
County,
Indiana
are
violating
the
PM2.5
standard.
The
adjacent
Kentucky
County
of
Carroll
has
relatively
high
emissions
for
the
area,
however,
it
was
evaluated
as
part
of
the
Cincinnati
area.

In
February
2004,
Kentucky
recommended
that
Jefferson
County
be
designated
nonattainment
and
that
Bullitt
and
Oldham
Counties
be
designated
attainment
for
the
PM2.5
standard
for
the
Louisville
MSA.

EPA
agrees
that
the
Kentucky
MSA
County
of
Oldham
be
designated
attainment/
unclassifiable
due
to
low
emissions
and
relatively
low
population.
EPA
agrees
that
Jefferson
County
be
designated
nonattainment
due
to
four
violating
monitors
in
the
County
and
is
modifying
Kentucky's
recommendation
to
include
Bullitt
County
in
the
Louisville
nonattainment
area
due
to
a
relatively
high
number
of
commuters
into
violating
Jefferson
County,
a
monitored
PM2.5
value
of
15.0
that
is
very
close
to
the
standard,
and
relatively
high
population
growth.

EPA
agrees
that
the
adjacent
counties
should
be
designated
as
attainment/
unclassifiable
due
to
low
population
growth,
a
low
percentage
of
workers
commuting
into
the
Louisville
MSA,
relatively
low
emissions,
and
large
distance
from
the
violating
monitors
in
the

is
approximately
6­

the
highest

is
approximately
twice

Although
Hardin
County's
population
is
the
third
largest
of
the
counties
analyzed
above,
its
population
growth
is
relatively
low.
Thus,
with
the
exception
of

6.4.3.3
Lexington
Area
The
Lexington
MSA
contains
the
Counties
of
Fayette,
Bourbon,
Clark,
Jessamine,
Madison,
Scott,
and
Woodford.
Fayette
County
is
violating
the
PM2.5
standard.

In
February
2004,
Kentucky
recommended
that
Fayette
County
be
designated
attainment
for
the
PM2.5
standard
for
the
Lexington,
KY
MSA,
and
the
remaining
MSA
counties
be
designated
attainment.
EPA
agrees
that
Fayette
County
should
be
designated
nonattainment
for
PM2.5
due
to
a
violating
monitor
(
South
Limestone).
EPA
is
modifying
Kentucky's
recommendation
to
6­
203
include
the
MSA
counties
of
Clark,
Madison
and
Woodford
and
the
adjacent
county
of
Mercer
in
the
Lexington
nonattainment
area.
Clark
and
Madison
Counties
are
included
significant
emissions.
Madison
County
also
has
relatively
high
population
and
population
growth,
and
relatively
high
VMT.
Woodford
County
as
nonattainment
due
to
the
level
of
emissions.
We
have
included
in
our
recommended
nonattainment
area
Mercer
County
that
is
adjacent
to
the
Lexington
MSA
with
a
violating
monitor,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
(
e.
g.,
power
plants)
which
we
believe
contributes
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
county,
including
such
a
large
facility,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
this
adjacent
county,
encompassing
the
large
facility,
should
be
designated
nonattainment.
EPA
agrees
that
the
remaining
MSA
Counties
of
Bourbon,
Jessamine,
and
Scott
in
Kentucky
be
designated
attainment/
unclassifiable
due
to
their
relatively
low
emissions,
low
populations,
low
VMT,
low
numbers
of
commuters
into
the
violating
counties,
and
small
point
sources.

EPA
agrees
that
the
adjacent
county
of
Pulaski
should
be
designated
attainment/
classifiable
for
the
PM2.5
standard,
although
it
has
significant
emissions
due
to
a
power
plant.
This
county
has
relatively
low
population,
low
population
growth,
and
low
VMT.
Further,
the
commuting
patterns
and
distance
from
the
violating
monitors
indicate
that
this
county
does
not
contribute
to
the
violations
in
the
area.
The
other
adjacent
counties
do
not
contribute
and
therefore,
will
be
designated
as
attainment/
unclassifiable.

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
EPA's
initial
nonattainment
recommendations
on
June
29,
2004,
include
the
MSA
counties
of
Clark,
Madison,
and
Woodford
and
the
adjacent
county
of
Mercer.
Upon
further
review
of
additional
information
provided
by
Kentucky,
EPA
is
revising
its
recommendations
and
designating
Clark,
Madison,
and
Woodford
Counties
as
attainment/
unclassifiable.
EPA
is
designating
a
portion
of
Mercer
County
as
nonattainment
and
the
remainder
of
the
county
as
attainment/
unclassifiable.

The
additional
analysis
provided
by
Kentucky
indicated
that
there
is
a
strong
localized
effect
on
the
violating
monitor
in
Fayette
County.
Fayette
County
has
two
monitors
located
in
Lexington,
Kentucky
which
are
1.9
miles
apart,
with
one
violating
at
a
design
value
of
15.6
and
one
attaining
at
a
design
value
of
14.9.
The
supplemental
submittals
from
Kentucky
provided
additional
data
and
analysis
to
demonstrate
that
the
monitor
located
on
the
University
of
Kentucky's
(
UK)
campus
is
violating
due
to
localized
impacts.
These
local
impacts
include:
emissions
from
112
UK
boilers
fueled
by
coal
and
natural
gas;
13
major
construction
projects
on
the
UK
campus
which
began
as
early
as
December
1999
and
have
just
been
completed
or
are
in
process;
and
several,
nearby
downtown
construction
projects
in
Lexington.
All
of
the
construction
projects
in
the
area
are
one
to
six
blocks
from
the
violating
monitor.

Clark
County,
KY:

Clark
County's
population
of
33,726
people
and
VMT
of
523,000
are
very
small
in
comparison
to
those
of
Fayette
County,
whose
population,
commuters,
and
VMT
are
substantially
higher
than
those
of
the
other
MSA
counties.
In
contrast,
Fayette
County,
with
one
violating
monitor,
has
a
population
of
263,618
and
VMT
of
2,764,000.
Clark
County
has
no
monitor.
Clark
County's
population
comprises
only
6.9%
of
the
total
MSA
population.
In
addition,
Clark
County
has
a
low
number
of
workers
(
4,777)
commuting
to
the
violating
MSA
County
of
Fayette
and
whose
15,487
workers
account
for
just
6.4%
of
the
total
number
of
MSA
workers.

Clark
County's
total
emissions
are,
in
tpy
(
and
%
of
the
MSA
emissions):
1,132
PM
(
19.4%),
9,647
SO2
(
53.1%),
6,622
NOx
(
18.1%),
and
2,374
VOC
(
6.8%).
Clark
County
does
contain
a
small
outlying
power
plant,
East
Kentucky
Power,
with
2001
emissions
of
6,846
tpy
of
SO2
and
6­
209
1,910
tpy
of
NOx.
These
factors
in
combination
with
Kentucky's
localized
impact
analysis
indicate
Clark
County's
emissions
are
not
contributing
to
the
PM2.5
violation
at
the
one
monitor
in
Fayette
County.

Madison
County,
KY:

Madison
County
has
no
large
point
sources
and
the
design
value
of
its
attaining
monitor
is
13.4.
The
County
has
a
relatively
small
population
of
73,334
and
a
low
number
of
VMT
of
944,000
in
comparison
to
Fayette,
the
violating
county,
whose
population
is
263,618
and
VMT
is
2,764,000.
Madison
County
workers
account
for
only
14.2%
of
the
total
number
of
commuters
in
the
MSA.
In
addition,
70%
of
the
County's
workers
commute
within
Madison
County.

Woodford
County,
KY:

Woodford
County
has
relatively
low
emissions
and
no
monitor.
Specifically,
County
emission
totals
are,
in
tpy
(
and
%
of
the
MSA
emissions):
559
tpy
PM
(
9.6%),
2,663
tpy
SO2
(
14.7%),
3,530
tpy
NOx
(
9.7%),
and
2,852
tpy
VOC
(
8.2%).
While
there
is
a
small
Kentucky
Utilities
power
plant,
the
highest
emissions
from
this
plant
are
only
1,117
tpy
NOx
and
2,087
tpy
SO2.
In
addition,
the
County
has
a
very
small
population
of
23,403
and
accounts
for
only
5.1%
of
all
the
commuters
in
the
MSA.
Only
5,020
workers
from
Woodford
County
commute
to
other
counties
in
the
MSA.
These
factors
in
combination
with
Kentucky's
localized
impact
analysis
indicate
Woodford
County's
emissions
are
not
contributing
to
the
PM2.5
violation
at
the
one
monitor
in
Fayette
County.

Mercer
County,
KY:

In
the
June
29,
2004,
letters
from
EPA
to
the
States
responding
to
their
designation
recommendations,
EPA
recommended
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
to
include
it
in
the
nonattainment
area.
Mercer
County
is
one
of
those
counties.

Mercer
County
has
low
population
(
21,047
compared
to
263,618
in
Fayette
County
where
the
city
of
Lexington
is
located),
low
population
density
(
84
people
per
square
mile
compared
to
925
in
Fayette
County),
low
VMT
(
224,000
compared
to
2,764,000
in
Fayette
County),
and
the
only
large
point
source
is
Kentucky
Utilities'
E.
W.
Brown
facility.
Mercer
County
has
no
monitor.

A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.
The
6­
210
Commonwealth
of
Kentucky
subsequently
submitted
a
partial
county
recommendation
that
included
the
E.
W.
Brown
facility.

After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifier
(
StateFIPs­
CoFIPs­
Tract#­
Block
Group#)
21­
167­
9605­

portion
of
Mercer
County
as
part
of
the
Lexington
nonattainment
area.

6.4.3.4
Huntington­
Ashland
Area
The
Huntington­
Ashland
MSA
contains
the
Kentucky
Counties
of
Boyd,
Carter,
and
Greenup;
the
West
Virginia
Counties
of
Cabell
and
Wayne;
and
Lawrence
County,
Ohio.
The
following
MSA
and
adjacent
counties
are
violating
the
PM2.5
standard:
Cabell
County,
West
Virginia
(
MSA)
and
Lawrence
(
MSA)
and
Scioto
(
adjacent)
Counties,
Ohio.

In
February
2004,
Kentucky
recommended
that
the
PM2.5
designation
for
Boyd
County
be
deferred
and
that
Greenup
and
Carter
Counties
be
designated
attainment
for
the
Huntington­
Ashland
MSA.
EPA
is
modifying
Kentucky's
recommendeation
to
include
Boyd
County
and
Lawrence
Counties
in
Kentucky
in
the
Huntington­
Ashland
nonattainment
area.
The
following
factors
played
a
significant
role
in
this
decision
for
Boyd
County:
attaining
monitor
reading
of
15.0,
at
the
standard;
significant
SOx,
NOx,
and
PM
emissions;
proximity
to
the
violating
MSA
counties;
controls
with
anticipated,
substantial
SOx,
NOx,
and
PM
emission
reductions
will
not
be
implemented
until
the
end
of
2005,
well
after
designations
are
made.
Lawrence
County,
Kentucky
is
included
due
to
significant
emissions
of
SOx
and
NOx
from
a
power
plant
and
its
close
proximity
to
the
violating
counties
in
the
MSA.
We
have
included
in
our
recommended
nonattainment
area
this
County
that
is
adjacent
to
the
Huntington­
Ashland
MSA
with
a
violating
monitor,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
(
e.
g.,
power
plant)
which
we
believe
contributes
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
this
county,
including
such
a
large
facility,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
this
adjacent
county,
encompassing
the
large
facility,
should
be
designated
nonattainment.

EPA
agrees
that
Greenup
and
Carter
Counties
in
Kentucky
should
be
designated
attainment/
unclassifiable
due
to
their
relatively
low
emissions,
low
populations,
low
VMT,
low
numbers
of
commuters
into
the
violating
counties,
and
small
point
sources.

The
recommendations
of
EPA
and
Kentucky
are

with
two
of
them
in

are
violating:
Cabell

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
Lawrence
County,
KY:

In
the
June
29,
2004,
letters
from
EPA
to
the
States
responding
to
their
designation
recommendations,
EPA
recommended
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
to
include
it
in
the
nonattainment
area.
Lawrence
County,
Kentucky,
is
one
of
those
counties.

Lawrence
County,
Kentucky,
has
low
population
(
15,784
compared
to
95,266
and
62,172
in
the
violating
MSA
counties
of
Cabell,
West
Virginia
and
Lawrence,
Ohio,
respectively),
low
population
density
(
38
people
per
square
mile
compared
to
338
in
Cabell,
West
Virginia
and
137
in
Lawrence,
Ohio),
low
VMT
(
163,000
compared
to
1,030,000
and
796,000
in
Cabell,
West
Virginia
and
Lawrence,
Ohio),
and
the
only
large
point
source
is
the
Big
Sandy
Power
Plant.
Lawrence
County,
Kentucky,
has
no
monitor.
6­
217
A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.
The
Commonwealth
of
Kentucky
subsequently
submitted
a
partial
county
recommendation
that
included
the
Big
Sandy
Power
Plant.

After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifier
(

there
appears
to
be
relatively
significant
population

to
indicate

However,
the

and
review
of
additional
information
received

6.4.3.5
Boyd
County
Area
Kentucky
anticipates
that
emissions
of
PM2.5,
SOx,
and
NOx
will
decrease
substantially
within
Boyd
County
over
the
next
two
years.
These
anticipated
emission
decreases
are
due
to
source
modernization
and
new
controls
being
implemented
at
two
major
sources
in
Boyd
County:
the
Marathon­
Ashland
Refinery
and
Calgon
Carbon
Corporation.

For
the
Marathon­
Ashland
Refinery,
the
facility
modifications
are
anticipated
to
be
completed
by
the
end
of
2005.
According
to
Kentucky,
based
on
2002
emissions
data,
this
would
mean
an
approximate
reduction
of
1,571
tons
per
year
of
SO2,
a
761
ton
per
year
reduction
in
NOx,
and
a
32
ton
per
year
reduction
in
particulate
matter.

For
Calgon
Carbon
Corporation,
the
May
2003
shutdown
of
two
of
their
activator
lines
resulted
in
SO2
emissions
being
reduced
from
this
facility
by
approximately
187
tons
in
2003.
Before
these
lines
can
be
reactivated,
scrubbers,
with
SO2
and
PM
control
efficiencies
of
90%
will
be
required
to
be
installed
on
these
units.
If
brought
back
into
operation,
these
units
will
have
controls
in
place
to
reduce
emissions
of
SO2
from
these
two
lines
to
approximately
32
tons
per
year.

Based
on
an
analysis
of
this
factor,
these
controls
will
not
be
implemented
in
a
timeframe
early
enough
to
influence
the
decision
for
Boyd
County
on
PM2.5
designations.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June

letter,
and

The
MSA
counties
of
Guilford,
Stokes,

EPA
agrees
that
Alamance,
Davie,
Yadkin,
Rowan,
Chatham,
Rockingham,
and
Iredell
Counties
be

Alamance
is
an

include
Charlotte,
the
Triad,
and
Hickory.

Wintertime:
More
northerly

generally
observed
prior
to

not
because
they
were

Counties
as
part
of
the
Greensboro

provided
by
the
State,
EPA
is
revising
its

and
is
designating
Forsyth,
Randolph

The
State
of
North
Carolina
has
taken
a
proactive
approach
to
solving
its
air
pollution
problems.
Several
programs
have
been
implemented
and
will
continue
to
be
implemented
to
control
PM2.5
precursors.
The
State
has
a
robust
PM2.5
monitoring
network.
The
Clean
Smokestacks
Act
requires
NOx
SIP
Call
controls
to
be
operated
year

and
requires
significant
emission
reductions
of
SO2
from
power
plants.
These
NOx
and
SO2
reductions
must
occur
within
the
boundaries
of
North

As
a
statewide

EPA
conducted
as
described
in
the
June

letter,
and
review
of
additional
information
received
after
our
initial

EPA
is
designating
the
following
counties
as

Hickory­
Morganton­

The
following
is
the
nine
factor
analysis
for
Hickory­
Morganton­
Lenoir,
NC.
The
Hickory­
Morganton­
Lenoir,
NC
Metropolitan
Statistical
Area
(
MSA)
contains
the
counties
of
Catawba,
Caldwell,
Burke,
and
Alexander.

In
February
2004,
North
Carolina
recommended
that
the
Unifour
Metropolitan
Planning
Organization's
(
MPO)
Planning
Boundary
in
Catawba
County,
be
designated
as
nonattainment.
The

for
the
Particulate

nonattainment
area
in
the
Hickory­
Morganton­
Lenoir
area.
EPA
is
modifying
the
recommendation
to
include
the
entire
county
of
Catawba
and
partial
county
boundaries
in
Burke
and
Caldwell
Counties.
Catawba
County
has
a
violating
PM
2.5
monitor.
The
partial
county
boundaries
in
Burke
and
Caldwell
Counties
follow
the
MPO
boundary
lines
which
were
the
boundaries
determined
in
the
8­
hour
ozone
designation
in
April
2004
for
the
two
counties.
Over
20
percent
of
the
commuters
from
Burke
and
Caldwell
counties
commute
to
Catawba
County
and
both
counties
contain
population
levels
that
indicate
contribution.
EPA
agrees
that
the
MSA
county
of
Alexander
and
the
adjacent
counties
of
Rutherford,
Iredell,
Cleveland,
and
Wilkes
be
designated
attainment/
unclassifiable.
These
counties
have
low
population,
and
are
low
commuting
into
Catawba
County,
distant
from
the
violating
monitor
in
Catawba
County.
The
remaining
adjacent
counties
all
have
low
emissions
and
low
population,
indicating
they
should
be
attainment/
unclassifiable.

area.

Factor
6:
Meteorology
The
following
meteorological
information
was
provided
by
North
Carolina.
This
summarizes
the
wind
directions
for
the
MSA
during
the
time
periods
when
PM2.5
values
are
the
highest.

Summertime:
southwesterly
winds
and
recirculating
patterns
dominate.
Main
urban
areas
of
influence
include
Charlotte,
the
Triad,
and
Hickory.

Wintertime:
More
northerly
and
stronger
northwesterly
winds
observed
that
during
the
summer.
High
PM2.5
is
generally
observed
prior
to
frontal
passages
when
high
pressure
is
in
control
or
during
strong
nocturnal
low­
level
temperature
inversions.
Year­
round
trajectories
indicate
influence
from
nearby
states.

The
information
provided
is
not
sufficient
to
provide
a
compelling
argument
to
exclude
counties
based
on
prevailing
winds.

Factor
7:
Geography/
topography
6­
231
There
are
no
significant
topographical
issues
associated
with
this
MSA.

Factor
8:
Jurisdictional
boundaries
The
8­
hour
nonattainment
boundary
designation
for
the
Hickory­
Morganton­
Lenoir
area
includes
the
entire
counties
of
Alexander
and
Catawba
and
partial
counties
of
Burke
and
Caldwell.
The
nonattainment
designation
in
Burke
and
Caldwell
counties
are
along
the
Unifour
Metropolitan
Planning
Organization
boundaries.
Catawba
County
is
located
geographically
between
Alexander
and
Lincoln
Counties,
which
both
have
monitors
violating
the
8­
hour
ozone
standard.

In
Catawba
County,
a
second
monitor
was
operated
approximately
10
miles
southwest
of
the
current
violating
Hickory
monitor.
This
monitor
was
further
removed
from
a
major
highway.
The
location
of
this
monitor
at
a
rescue
squad
and
was
not
able
to
continue
at
that
location.
While
in
existence
for
seven
quarters,
this
monitor
showed
an
average
of
1.89
µ
g/
m3
lower
than
the
current
violating
monitor.
Therefore,
the
state
believes
that
this
monitor
would
have
continued
to
show
attainment/
unclassifiable
if
it
remained
in
existence
to
collect
three
years
of
data.

However,
in
2004,
Duke
Power
began
installation
of
flue
gas
desulfurization
(
scrubber)
equipment.
This

EPA's
initial
nonattainment
recommendations
on
June
29,
2004,
included
a
portion
of
Burke
and
Caldwell
Counties.
Upon
further
review
of
additional
information
provided
by
the
State,
EPA
is
revising
its
recommendation
and
is
designating
Burke
and
Caldwell
Counties
as
attainment/
unclassifiable.

The
State
of
North
Carolina
has
taken
a
proactive
approach
to
solving
its
air
pollution
problems.
Several
programs
have
been
implemented
and
will
continue
to
be
implemented
to
control
PM2.5
pollution.
The
State
has
a
robust
PM2.5
monitoring
network.
The
Clean
Smokestacks
Act
requires
NOx
controls
to
be
operated
year
round
and
requires
substantial
SO2
reductions
from
6­
232
power
plants.
The
NOx
and
SO2
reductions
must
be
generated
within
the
State.
As
a
statewide
effort,
several
mobile
source
controls
have
been
implemented
including
I/
M
programs
in
Burke
and
Caldwell
Counties
beginning
July
1,
2005.
Burke
County
has
expected
decreases
in
NOx
of
1.29
tpd
and
VOC
of
0.23
tpd
while
Caldwell
County
has
expected
decreases
in
NOx
of
0.20
tpd
and
VOC
of
0.17
tpd.
Additionally,
Burke
and
Caldwell
Counties
are
in
the
Unifour
Early

Compact
and
this
area
shows
attainment
of
the
8­

Greenville­

In
February
2004,
South
Carolina
recommended
that
the
entire
state
be
designated
attainment.
Currently,
all
monitors
with
three
years
of
complete
data
are
attaining
the
Particulate
Matter
standard
of
15.0
micrograms
per
cubic
meter
(
µ
g/
m3).
However,
Greenville
County
has
a
monitor
that
has
not
been
in
operation
for
three
years,
but
is
indicating
potential
to
violate
the
PM
2.5
standard.
Anderson
and
Spartanburg
counties
have
emissions
and
population
levels
that
potentially
contribute
to
the
high
levels
at
the
Greenville
monitor
in
question.
Therefore,
EPA
is
modifying
the
State's
recommendation
to
designate
Anderson,
Greenville
and
Spartanburg
counties
as
unclassifiable.
Once
the
monitor
has
operated
for
three
full
years,
EPA
in
6­
233
conjunction
with
the
State
will
reassess
the
situation
and
revise
the
designation
based
on
three
years
of

which
are
attached
to
the

which
is

Additionally
we
have
included
in
our
recommended

AL,
that
is
adjacent

that
is
generally

and
that
contains
an

facility
or
facilities
(
e.

which
we
believe
contribute

We
have
included
this
county
in
our

in
order
to
ensure
that
a

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
6­
242
EPA's
initial
nonattainment
recommendation
on
June
29,
2004
included
Marion
County,
TN
as
part
of
the
Chattanooga
nonattainment
area.
Upon
further
analysis,
including
the
review
of
additional
material
submitted
by
the
state,
EPA
is
revising
its
recommendation
and
designating
Marion
County
as
attainment/
unclassifiable.

Marion
County,
TN
Marion
County
has
a
small
population
(
27,654)
and
population
density
(
55
people/
mile2).
There
are
no
large
point
sources
and
the
County
only
contributes
17.2
percent
of
the
total
MSA
PM2.5
emissions
(
679
tpy),
7.1
percent
of
the
total
SO2
emissions
(
477
tpy),
and
10.0
percent
of
the
total
NOx
emissions
(
3156
tpy).
In
addition,
the
topography
analysis
indicates
that
the
Lookout
Mountain
Ridge
(
2100
feet)
separates
the
Marion
County
emissions
from
the
violating
monitors.
The
County
is
located
to
the
west
of
the
ridge
while
the
violating
monitors
reside
to
the
east
of
the
ridge.

McMinn
County,

See

Section

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
county
as
nonattainment
for
the
Chattanooga,
TN­
GA
area:
Hamilton.

6.4.6.2
Knoxville
Area
The
Knoxville,
TN
MSA
contains
the
counties
of
Anderson,
Blount,
Knox,
Loudon,
Sevier
and
Union.
Based
on
air
quality
data
for
2001­
2003
the
following
MSA
counties
contain
PM2.5
ambient
air
monitors
(
Design
values
are
included
in
parenthesis):
Knox
County
(
16.8),
Blount
County
(
14.4),
and
Loudon
County
(
15.4).
Two
adjacent
Tennessee
counties
also
contain
PM2.5
monitors:
Roane
County
(
14.2),
and
McMinn
County
(
14.6).

In
a
February
12,
2004
letter,
the
State
recommended
that
Knox,
Roane,
and
McMinn
Counties
be
designated
nonattainment
based
on
2000­
2002
monitoring
data.
The
State
revised
its
recommendation
on
May
7,
2004,
to
recommend
that
McMinn
and
Roane
Counties
be
designated
attainment
due
to
2001­
2003
data.
Therefore,
the
State's
current
recommendation
for
the
Knoxville
MSA
PM2.5
nonattainment
area
only
includes
Knox
County
and
recommends
that
all
other
MSA
and
adjacent
counties
be
designated
attainment.
The
State
submitted
some
justification
for
this
recommendation,
however,
they
indicated
that
the
detailed
emission
information
would
be
provided
at
a
later
date.
Union
County
has
very
small
amounts
of
PM2.5
and
precursor
emissions,
indicating
no
contribution.
Therefore,
EPA
agrees
that
Union
County
should
be
designated
attainment/
unclassifiable.
Roane
and
McMinn,
counties
adjacent
to
the
MSA,
currently
contain
attaining
ambient
air
monitors,
however,
Roane
and
McMinn
counties
have
significant
SO2
and
NOx
emissions
which
contribute
to
the
violations.
EPA
is
modifying
the
State's
recommendation
and
will
review
the
additional
information
during
the
120
day
period
following
the
notification
letter.

We
have
included
in
our
recommended
nonattainment
area
Roane
County
that
is
adjacent
to
the
Knoxville
MSA
with
a
violating
monitor,
that
is
generally
rural
in
character,
and
that
contains
an
identifiable
large
emitting
facility
or
facilities
(
e.
g.,
power
plants)
which
we
believe
contributes
to
the
nearby
nonattainment
problem.
We
have
included
this
county
in
our
initial
recommendations
in
order
to
ensure
that
a
sufficient
portion
of
the
county,
including
such
large
facilities,
is
included
within
the
boundaries
of
the
nonattainment
area
as
part
of
the
final
designations.
We
invite
you
to
submit
to
us
a
recommendation
as
to
what
portion
of
this
adjacent
county,
encompassing
the
large
facility
or
facilities,
should
be
designated
nonattainment.

Based
on
EPA's
analysis
of
the
available
information,
EPA
is
modifying
the
recommended
nonattainment
area
to
include
all
of
the
MSA
counties,
except
Union,
and
the
adjacent
counties
of
Roane
and

Justifications
for
Changes
to
EPA
Recommendations
Contained
in
the
June
29,
2004
Letters
to
States
EPA's
initial
nonattainment
recommendation
on
June
29,
2004
included
McMinn,
Roane,
and
Sevier
Counties,
TN
as
part
of
the
Chattanooga
nonattainment
area.
Upon
further
analysis,
including
the
review
of
additional
material
submitted
by
the
state,
EPA
is
revising
its
recommendation
and
designating
McMinn
County
as
unclassifiable
and
Sevier
County
as
attainment/
unclassifiable.
EPA
is
designating
a
portion
of
Roane
County
that
encompasses
the
TVA
Kingston
power
plant
as
nonattainment.
The
remainder
of
Roane
County
will
be
designated
as
attainment/
unclassifiable.

McMinn
County,
TN
The
McMinn
County
emissions,
represented
in
the
table
below,
indicate
that
the
county
does
not
contribute
to
the
violations
in
Knoxville.
The
county
is
located
outside
of
the
Metropolitan
Statistical
Area,
has
a
small
population
(
50,051),
and
low
population
density
(
116
people/
mile2).
McMinn
County
and
the
State
of
Tennessee
submitted
additional
information,
correcting
the
emissions
for
Bowater
Newsprint
and
for
McMinn
County.
The
corrected
emissions
data
for
McMinn

emissions
are
represented
in

Based
on
incomplete
monitoring
data
and
data
substitution
not
being
a
viable
alternative,
EPA
has
changed
its
June
2004
recommendation
of
nonattainment
and
is
designating
McMinn
County
unclassifiable.
The
county
had
monitoring
data
for
2000­
2002
that
was
violating
and
has
incomplete
data
for
2001­
2003.
Applying
the
data
substitution
policy
will
not
confirm
attainment.

Sevier
County,
TN
Sevier
County
has
low
emissions.
The
data
indicate
that
the
county
only
contributes
7.0
percent
of
the
total
MSA
PM2.5
emissions
(
711
tpy),
0.8
percent
of
the
total
SO2
emissions
(
433
tpy),
and
4.6
percent
of
the
total
NOx
emissions
(
2838
tpy).
The
County
is
located
within
the
Metropolitan
Statistical
Area,
however
it
has
a
small
population
(
74,456),
10.6
percent
of
the
MSA
population.
Additionally,
the
County
has
a
population
density
of
126
people/

which
is
low
compared
to
Knox
County
that
has
a
population
density
of
765
people/

Roane
County,
TN
In
the
June
29,
2004,
letters
from
EPA
to
the
States
responding
to
their
designation
recommendations,
EPA
recommended
the
designation
of
a
number
of
counties
primarily
because
of
high
pollutant
emissions
from
power
plants.
Most
of
these
plants
were
located
in
nearby
counties
adjacent
to
the
metropolitan
area
(
as
defined
either
by
the
1999
or
2003
OMB
metropolitan
area
definitions).
EPA
suggested
that
a
State
could
provide
a
partial
county
boundary
that
would
encompass
the
relevant
power
plant
to
include
it
in
the
nonattainment
area.
Roane
County,
Tennessee
is
one
of
those
counties.
Roane
County
has
low
population
(
52,316
compared
to
389,327
in
Knox
County,
the
predominant
county
in
the
Knoxville
MSA),
low
population
density
(
145
people
per
square
mile
compared
to
765
in
Knox
County),
low
VMT
(
784,000
miles
compared
to
5,135,000
in
Knox
County
),
and
the
only
large
point
source
is
the
Kingston
Fossil
Plant.
Additionally,
Roane
County
has
a
monitor
that
is
indicating
attainment
with
a
design
value
of
14.2
(
2001­
2003).

A
number
of
states
responded
to
this
suggestion
with
a
series
of
connected
townships
or
other
unique
boundaries.
Some
states
also
suggested
an
alternative
approach
in
which
partial
county
areas
for
power
plants
in
some
cases
could
be
small
"
free­
standing"
boundaries
that
are
considered
part
of
the
nearby
nonattainment
area.
In
this
way,
it
would
not
be
necessary
to
include
additional
townships
or
other
minor
civil
divisions
comprising
an
odd­
shaped
"
land
connector"
extending
from
the
main
part
of
the
nonattainment
area
to
the
power
plant.
The
State
of
Tennessee
subsequently
submitted
a
partial
county
recommendation
that
included
the
Kingston
Fossil
Plant.

After
considering
these
comments
from
the
States,
EPA
agrees
that
such
an
approach
is
preferable
in
cases
where
a
partial
county
nonattainment
boundary
has
not
already
been
established
for
that
source
(
e.
g.
partial
county
boundaries
recently
established
for
8­
hour
ozone
nonattainment
areas).
For
purposes
of
consistency,
EPA
has
decided
that
free­
standing
portions
of
nonattainment
areas
should
be
based
on
a
pre­
existing
boundary
for
a
minor
civil
division
(
such
as
a
township
or
tax
district)
or
other
boundary
defined
for
governmental
use
(
such
as
a
census
block
group
or
census
tract).
Accordingly,
this
kind
of
partial
county
boundary
should
not
6­
250
be
defined
simply
as
the
boundary
of
the
facility.
Therefore,
EPA
is
designating
the
census
block
group
identifier
(
StateFIPs­
CoFIPs­
Tract#­
Block
Group#)
47­
145­
0307­
2
portion
of
Roane
County
as
part
of
the
Knoxville
nonattainment
area.

Based
on
the
analysis
EPA
conducted
as
described
in
the
June
29,
2004
letter,
and
review
of
additional
information
received
after
our
initial
analysis,
EPA
is
designating
the
following
counties
as
nonattainment
for
the
Knoxville,
TN
area:
Anderson,
Blount,
Knox,
Loudon,
and
Roane
(
