INTERIM OPINION & ORDER OF THE BOARD (by Mr. Dumelle)
This is a consolidated action. The first case (PCB 72-199) was an
enforcement action filed by the Agency on May 10, 1972, alleging that
Southern Illinois Power Cooperative (hereinafter (!ISIPC?t), in the operation
of its electric power generating station near Marion, Illinois, caused the
discharge of sulfur dioxide, flyash and other contaminants into the atmosphere
so as to cause air pollution, in violation of Section 9(a) of the Environmental
Protection Act (uAct~~)and also in violation of Rule 2-2.53 of the Rules and
Regulations Governing the Control of Air Pollution CRules~). The second
case was a Petition for Variance filed by SIPC on June 13, 1972, requesting
until April,1975 to achieve full compliance with the Act and Rules.
A hearing was held on August 7, 1972 at which time the parties presented
a Stipulation of Facts and the Agency filed its Recommendation and some
evidence was heard.
SIPC is an Illinois nonprofit corporation engaged in the business of pro-
ducing and generating electric power at its 100 megawatt coal-burning steam
turbine power plant in Williamson County. The plant consists of three 33
megawatt units each fired by double 7-foot radial cyclone burners equipped

with mechanical multiple-cyclone dust collectors. Two of these boiler
units exhaust into one stack and the third unit exhausts into a separate
stack. Each stack is 210 feet high. The plant serves 27, 000 customers.
The plant is expected to consume 250, 000 tons of coal and 60, 000 gallons
of oil during 1972. The blended coal will have an average heating value of
10, 700 BTU per pound with an average ash content of 14 percent and an average
sulfur content of 3. 5 percent.
Stack tests were made in June, 1970 indicating an emission rate of
0. 44 pounds per million BTU which was allowable under the Regulations
at that time. According to stack tests run in October, 1971, the average
emission rate for particulates was 0. 67 pounds per million BTU, which
rate continues at the present time. Rule 2-2. 53 of the Rules (see also
Rule 203 of the Air Pollution Control Regulations, effective April 14, 1972)
sets a limitation of 0. 45 pounds per million BTU.
SIPC intends to install three electrostatic pr ecipitators having an
efficiency of 96 removal for particulates so that the average emission
rate will be reduced to
.
04 pounds per million BTU. The cost is estimated
at $2, 000, 000. SIPC has proposed a time schedule as follows:
Start design
May, 1972
Start erection of first precipitator
May, 1973
Startup of first precipitator
April, 1974
Startup of second precipitator
October, 1974
Startup of third precipitator
April, 1975
The AgencyTs recommendation states that the program submitted by the
petitioner is adequate to satisfy particulate emission regulations under the
Pollution Control Board Regulations, Chapter 2, Part II, Rule 203(g) but
is excessively prolonged by a period of three months. We also question
the length of time requested. We are unsure from the record as to why
the startup time for the three precipitators must each be six months apart.
It would appear that all three precipitators could be installed within oily
one six-month period.
In years past the ash storage area has on the occasion of strong southerly
winds caused objectionable situations with residents in the immediate vicinity.
The Agency recommends that the petitioner notify the Division of Land
Pollution and Water Pollution Control within 60 days of the Board order of
the procedure used to dispose of their fly ash in their ash ponds. We also
V/b

find the need for the submission of a dust and ash control program. In
addition, we need more information regarding the availability of alternate
power, particularly from Central Illinois Public Service or Illinois Power
since the testimony indicates that there will be a new transmission line in
use by the end of 1972.
We will grant only a 90-day variance at this time. During that period
we expect that the petitioner will submit a verified statement to the Board
and Agency indicating any reasons why all three precipitators cannot be
started up within the six months period beginning April, 1974. Furthermore,
the petitioner should submit its dust and ash control program within those
90 days. We will decide the question of penalties in our final order.
This opinion constitutes the Board!s findings of fact and áonclusions
of law.
ORDER
Southern Illinois Power Cooperative is granted a variance for 90 days
until January 17, 1973, during which time the following shall be submitted
to the Board and Agency:
1.
A verified statement indicating any reasons why all three
precipitators cannot be started up within the six months period
beginning April, 1974.
2.
A dust and ash control program.
The Agency shall respond within 21 days from the receipt of said
additional information. This proceeding shall remain open for further
orders.
