ORDER
OF
THE
BOARD
(by Mr. Dumelle):
Commonwealth Edison filed a Motion for Stay of the October
4,
1973 Order.
The Motion for Stay was received on November
9,
1973.
Edison requests that payment
of the $31,000 penalty be stayed until
the Illinois Supreme Court decides whether the Board’s discretionary
authority to impose monetary penalties violates the Illinois
Constitution in City of Waukegan v.
EPA.
The Board has been
granting
stays orthe payment of all penalties, when requested
to
do so, pending final resolution of this question.
Edison further

placed in service,
in order
to verify the effects
of such operation
on ambient air quality in the Waukegan area; modify the restric-
tions on the operation of the Waukegan station imposed by Section
2(b)
of the Order to
allow Edison to operate Waukegan units
at those
minimal units loadings not requiring the use of No.
2 distillate
fuel
oil which minimum loadings were not included
in the record of
the proceedings;
and modify the schedule for shutdown of the
Sabrooke Units
3
and
2
(and correct the scheduling date for the
shutdown of Unit
1)
for conversion to oil-firing to reflect the
delays that Edison has experienced in the availability of equipment.
Because
of
the
potential
for
major
health
risks
demonstrated
in
the
record,
the
Board
feels
that
Powerton
Units
1-4 should be
operated before Waukegan above
a minimal value.
The Board notes
that at
a minimum, Powerton Units
1-4
would
be
operated
at
a
level
to
insure
first
contingency
protection
and
prevent
icing
on
trans-
mission lines
during the six-month
period that the Waukegan variance
is
in effect.
The Board therefore retains the Order of Operation
which required Edison
to operate Powerton Units
1-4 ahead of Waukegan
above a minimal level contained
in Section
2(b)
of the Order in
PCB 73-40 with one exception.
Edison will operate all available
coal-fired units before placing peaking units
in operation.
This modi-
fication is
in light
of the critical supply of No.
2 fuel oil and
natural
gas
which Edison uses
as peaking fuel.
Edison has taken steps
to comply with Section 2(b)
of the
Order which required them to install ambient air monitoring equip-
ment.
Edison seeks
to modify the operating restrictions placed on
the Waukegan Station in order to allow it to operate Waukegan
Station
at
full
load once the ambient air monitoring
installations
have been placed in service,
in order to verify the effects of such
operation on ambient air quality
in the Waukegan area.
The Board,
therefore modifies the operating restrictions
found in Section 2(b)
in
order
to
allow
Edison
to
conduct
such
ambient
air
monitoring
tests.
If, short term particulate and SO7 primary air quality standards
are
violated, Edison shall immediately notify the Agency and take
such steps
as
is necessary to protect the citizens of Waukegan.
Edison has presented the Board, through an Affidavit of
Mr.
Gilliom, Superintendent of the Waukegan Station, information
which shows
the
minimum loading which may be maintained by all coal
operation.
The 315 megawatt operating restriction is hereby amended
to read 355 megawatts which
is
the minimum net operational level
which may be maintained
by coal-firing alone.
To maintain the
315 megawatt restriction,
Edison would need to use between 650 to
2,000 gallons
of
No.
2 oil per hour to insure that the flame
in
each unit
is stabilized
in order to prevent boiler explosions.
Edison may, therefore operate Units
5,
6,7,
and
8 at
24,
24,
153,
and 153 megawatts,
respectively.

Edison has presented additional testimony,
as shown in
the
Affidavit of Mr. DeChaud, that delay in the receipt of
equipment
has prevented the performance of all necessary work to insure
conversion of the Sabrooke Units to oil.
Edison has requested
several brief extensions of the conversion date.
Because of the
short time period involved,
one month,
the Board amends its Order
to reflect the date.
The Board hereby amends
its Order as follows:
A.
By amending Section
2(b) relating to
the Waukegan
Station to read:
“From the single stack emission limit of 0.60 lbs/MBtu
and the site emission limit of 0.24 lbs/MBtü, Rule 3-3.112
of the Air Rules,
and Rule 203(g),
on the condition that
the total Waukegan Station not be operated above
355 megawatts
(the minimum loadings not requiring the use of distillate
oil) unless
all other available Edison capapcity (including
the Sabrooke Station and Powerton Units
#1-4 but excluding
the fast-start peaking units)
has been placed in service.”
B.
By amending Subsection
3,
one of the paragraphs
containing
terms
and conditions of the Waükegan Station variance, to read:
“Edison is
to establish
a nine station network of Hi-Vol
samplers and SO2 monitoring devices.
Locations
of the moni-
toring networks and all other relevant details
shall be sub-
ject to Agency direction and approval.
Daily data is
to be
furnished to the Agency.
Once the network of monitoring
stations has been placed in service,
the limitation on the
operation of the waukegan Station herein specified shall
be suspended to allow the accumulation of relevant data to
enable the Board to better evaluate the actual effects of
Waukegan Station emissions on ambient air quality,
if either
24
or 3 hour SO2 and particulate air quality standards are exceeded,
Edison shall immediately notify the Agency and take necessary steps
to protect the~surroundcitizens
as Edison or the Agency deem
necessary.
This suspension only applies during testing periods.
C.
By amending Section 1(b) relating to the Sabrooke Station
to read:
“For Units
#3,
2, and 1, until those units
can be shut
down for conversion
to oH firing on January
1,
1974,
May
1,
1974 and September 30,
1974, respectively, on the
condition that in the interim these units will be operated
only after all other available Edison capacity (excluding
Powerton Units
#1-4,
the fast-start peaking units,
and the
Waukegan Station above 355 megawatts)
has been placed
10
—
147
-4-
in
serv:i.ce,
except that any one
of the units may be
operated
at
the
minimum
level
necessary
to
provide
steam
cor water demineralizing and heating the station,
or
to
prevent
stack
deterioration.”
IT
IS SO
ORiJE RED.
