INTERIM ORDER OF THE BOARD

(by Mr. Henss):

Commonwealth Edison Company has filed a Motion requesting

extension of an Interim Variance previously granted by the

Board on April

4, 1974.

The April

4,

1974 Order extended

(1)

a variance previously granted on April

4,

1973 and amended

on November 29, 1973 relative to

the Waukegan Station and

(2)

a variance granted on October 4,

1973 and amended on November 29,

1973 and again on December 20, 1973 relative to the Sabrooke

Station.

The Motion

is hereby allowed and Edison is granted

an extension of the interim variance until August

4,

1974 for

its Waukegan Station and its Sabrooke Units

1,

2 and

3.

The

shutdown dates

for Sabrooke Units

2 and

3 wjll now be August

4,

1974.

On May

9,

1974

the Federal Energy Office orally gave

Edison permission to use oil in Sabrooke Unit

ff4 and to proceed

with conversion of either Sabrooke Unit

2 or

3 to oil firing.

However, Edison reports that no ruling has been made relative

to the oil conversion of the remaining two units.

If Edison

were required to adhere to the previous interim variance, Sabrooke

could experience difficulties in meeting that Station’s summer

peak load requirements.

Hearings are currently proceeding on Edison’s variance

request for five stations,

including the Waukegan and Sabrooke

Stations.

Neither

the

Agency

nor

the

Attorney

General

has

expressed

any

objection

to

this

interim extension and the Board

believes

that

this

extension

will

allow

for

orderly

completion

of

the

record which is requisite for our final decision in this matter.

IT IS SO ORDERED.
