John,

The
following
is
in
reference
to
the
RACT/
NOx
SIP
call/
CAIR
discussion
in
the
draft
Response
to
Comments
document:

CAMD
has
reviewed
the
8
units
in
Illinois
and
Indiana
identified
in
Doug
Grano's
list
of
uncontrolled
units,
which
is
based
on
the
2010
base
case
spreadsheet
that
was
the
basis
for
the
analysis
described
in
the
draft
Response
to
Comments.
The
draft
RTC
discussion
says
8
of
the
units
identified
as
uncontrolled
in
2010
are
located
in
the
Chicago
area,
so
it
appears
that
these
would
be
the
same
units.

CAMD's
review
indicates
that:

­
Four
of
those
IL
units
have
documented
low­
NOx
burner
controls
(
2
at
Wood
River
plant
based
on
EIA
data;
2
at
Will
County
plant
based
on
2005
data
reported
to
EPA).

­
One
IN
unit,
Stateline,
appears
to
have
LNB
based
on
the
emission
rate.

­
The
Dean
Mitchell
plant
in
IN,
which
has
2
units
identified
as
uncontrolled,
has
not
operated
for
a
year
and
a
half
and
may
be
permanently
shut
down
according
to
press
reports
(
though
CAMD
has
not
verified
that
report).

So,
of
the
8
EGUs
in
the
Chicago
area
that
originally
were
identified
as
uncontrolled,
5
have
low
NOx
burners,
1
may
be
uncontrolled,
and
2
have
been
shut
down
for
a
year
and
a
half.
