Subject:
Changes
to
Alabama's
Particulate
Monitoring
Network
Plan
Dear
Mr.
Neeley:

In
July
2004,
Alabama
and
Georgia
jointly
submitted
a
request
to
revise
our
respective
Particulate
Monitoring
Plans
to
use
spatial
averaging
in
the
Columbus,
Georgia,
Metropolitan
Statistical
Area
(
MSA).
In
your
November
23,
2004
letter,
you
conveyed
to
us
that
EPA
had
determined
that
the
case
for
spatial
averaging
was
not
made
in
our
July
2004
submittal
due
to
concerns
with
emission
sources
in
the
area
not
similarly
impacting
all
three
monitors.
Enclosed
is
a
revised
plan
to
spatially
average
two
monitors,
one
in
Phenix
City,
Alabama,
and
one
in
Columbus,
Georgia,
at
the
health
department.
We
believe
your
concerns
with
our
previous
monitoring
plan
revision
regarding
the
impact
from
emission
sources
are
resolved
by
spatially
averaging
these
two
monitors.
The
Air
Quality
System
(
AQS)
site
identification
number
for
our
monitor
is
011130001.
Georgia's
PM2.5
monitor
AQS
site
identification
number
is
132150001.
The
attached
document
includes
the
data
that
supports
this
proposal
and
detailed
information
which
describes
the
new
monitoring
planning
area.

Further,
in
accordance
with
the
spatial
averaging
rules,
ADEM
is
requesting
that
the
designation
of
the
Russell
County
monitor
be
changed
from
SLAMS
to
Core­
SLAMS.
This
monitor
is
being
operated
in
accordance
with
the
requirements
for
Core­
SLAMS
sites.

We
therefore
request
that
EPA
approve
this
revision
to
our
Particulate
Monitoring
Network
Plan.
We
would
appreciate
your
expedited
review
and
approval
of
this
revised
plan
in
light
of
the
deadlines
in
the
recent
PM2.5
designation
rule
signed
by
the
Administrator.
