ORDER OF THE BOARD

(by Dr. Satchell):

On November 26 and December 20, 1979 Central Illinois

Public Service

(CIPS)

filed motions

to stay NPDES permit condi~

tions

for two plants:

Grand Tower Power Station and Hutsonville

Power Station.

The contested conditions involve pretreatment,

prior to discharge into an ash pond~of boiler chemical cleaning

wastes which are generated only when the boilers are cleaned

every two or three years.

Cleaning is scheduled for Grand Tower

in May,

1980 and Hutsonville in March, 1980.

Petitioner

alleges

that pretreatment plants cannot be built in time to allow clean~

ing of these boilers as scheduled and that

it is unlikely the

hearings will be concluded in time for decision prior to the

scheduled cleanings.

On December 12 and 24 the Environmental

Protection Agency

(Agency)

filed objections

to the motions

to

stay.

These are renewed permits and the contested provisions

are new.

The Agency has not pointed to regulations which require

it to include the contested conditions,

Since they appear to be

new discretionary conditions the motions to stay will be granted.

IT IS SO ORDERED,

I, Christan

L. Moffett,

Clerk of the Illinois Pollution

Control Board, hereby certify the above Order wa

adopted on the
