OPINION AND ORDER OF THE BOARD

On May 25,

1973, Petitioner, Illinois Power Company, filed

with this Board its Petition to Extend Variance.

Petitioner

operates an electric power generating station known as Vermillion

Station located in Edgar County,

Illinois.

That station consists

of two pulverized coal-fired units and one oil fired fast start

unit.

On September 30,

1971,

after a hearing had been held,

this

subject to certain

conditions, for Unit 1 until September

30,

1972, subject to extension

until June

30, 1973 and for Unit

2 until September

30,

1973,

subject

to extension until December 31, 1973.

It

is Unit

2 that is the

subject of this variance request.

Petitioner alleges that it has complied with the conditions

of our previous Order and that it is impossible to complete the

installation of the precipitator on Unit

1 prior to June 30, 1973

and to complete the installation of the precipitator on Unit 2

prior to December 31,

1973.

The precipitator

on Unit

1 was completed

and put into operation in June of

1973 as required by the Order.

Petitioner further alleges that work

is continuing on schedule

for the precipitator on Unit 2.

Delivery of the precipitator com-

ponents has begun,

construction of the foundations is complete and

the structural steel work is underway.

Petitioner states that,

barring unforeseen occurrances beyond Petitioner’s control, the

precipitator for Unit

2 can be completed by December 31,

1973.

Petitioner urges that continued operation of Unit

2

is necessary

and essential if Petitioner is

to maintain the reliability of the

supply of electric power to the public and that maintaining

facility to observe progress made in completing the electrostatic

precipitators.

The Agency is of the opinion that Petitioner has

made good progress in completing the precipitators.

Structural

steel construction on the electrostatic precipitator of Unit 2

began on June 4,

1973 and many of the components have been delivered.

Unit 2 is scheduled to come off line on November

1,

1973 and the

precipitator on this unit should be completed in time to allow the

unit to come back on line by January 13, 1973.

The Agency has

received no comment from the public concerning this variance.

This Opinion constitutes the findings of fact and conclusions
