Dear Mr. Johns-on:
Dynegy offers this letter to clarify a misunderstanding surrounding language in the July 26,2007
Opinion
and
Order
of
the
Illinois Pollution
Control Board
in
R06-26,
Proposed New
Clean
Air
Interstate
Rules (CAIR), S02, NOx Annual and NOx
Season Trading Programs,
35
ILL.
ADM.
CODE
225, Subparts
A,
C, D,
E,
and
F. In the Joint Motion to Amend the Proposed
Rulemaking
filed
on
March
13,2007
Dynegy and lEPA agreed that
D
ynegy's pending
Motion to
Dismiss would be withdrawn if the Board included the offered amended language in the Board's
First Notice,
On
page 6 of the PCB, Opinion
and
Order of the
Board,
in
the paragraph
labeled "Motion lo
Dismiss
and
Amend"
the Board correctly states that "on March
13,2007,
IEPA
and Uynegy filed
a joint
motion to
amend
Section
225.465(b)
(4)
(B) of
the
proposed
rule
to
address
Dynegy's
concerns regarding the manner in which the Clean
Air
Set
Aside (CASA)
provisions
penalized
sources with
consent decrees
relative
to
their baghouse projects."
The Board
also correctly
states
that Dynegy
requested
that the Board
stay action on the
motion
to dismiss and that Dynegy and
the
IEPA
agreed that
if
the
Board included the offered amendatory language of the Joint Motion
in the
Board's First
Notice of the Illinois Clean Air Interstate Rule,
Dynegy
would withdraw its
Matian
to
Dismiss.
However, the
Board
incorrectly
states
rhat its
April 19,2007
First-Notice Opinion and Order
incorporated the amendatory language offered by
Dynegy/lEPA
in the Joint Motion and that
Dynegy had Fdiled
to
file the
promised
withdrawal ofthe Motion to Dismiss.
In
fact a
comparison
of
the amendatory language offered
by
DyncgyiIEPA
in
the
Joint Motion,
the
First-
Notice Opinion and Order, and the Second-Notice Opinion and Order clearly illustrates that at
First-Notice
rule
at Section
225.465
(b) (4) (B) in the very last line it uses the term "heat ratio"
instead of
the term "heat rate", the term used
in
offered amendatory language and
upon Second-
Notice. This First-Woticc error, while appearing
to
be a
typog~aphical error,
significantly

The Honorable Thomas

Johnson

changed
the
meaning
of
the
provision. It
was
one of many
changes
that were corrected
or
requested
between
First
and Second
Notice.
Since
the lang~tage
uscd
by
the
Roard
in
its
First Notice differed in a significant
manner
from the
offered amendatory
language
of the
Joint Motion, Dynegy
was
not
in
a
position
to withdraw the
Motion
to
Dismiss, nor
was
it
required
to
do
so
under
its agreement with XEPA,
Upon Second-
Notice, when
he
actual language change was
made, the
Board,
upon
its own
motion, struck
Dynegy's Motion
ta
Dismiss making
it
impossible for Dynegy to withdraw the
Motion
to
Dismiss. Had the
change
been made at First-Notice
or
were the Motion
to
Dismiss
still
alive
following Second Notice, Dynegy would
have promptly
filed
the promised withdraw
of
the
Motion
to
Dismiss.
Hopefully,
this
letter provides
some
clarity as to
the
actions
of
Dynegy
in this regard. We have
arranged for
a
copy
of
this
letter
to
be
placed
in the
nrlernaking
docket for PCB Docket No.

26.
Please
advi
se
should
you have any conirnerlts
or concerns.
