OPINION OF THE BOARD

(by Mr. Kissel):

On February

21,

1972, Central

Illinois Public Service Company

(CIPC0)

submitted a Petition

for Clarification to the Board.

This

Petition sought clarification of Paragraph

2 of the Board Order

which reads as follows:

“2.

(PCB 71—262)

From Units #1 and

#2, at the Hutson-

ville Station, until January

1,

1974, provided that:

a.

Units

#1 and

#2 shall be on

“hot standby”

as defined in the Board’s opinion only

until September

30,

1972; and

b.

After September

30.,

1972, Units

#1 and #2

shall be placed on “cold standby” as de-

fined in the opinion,

only until January

1,

1974.”

CIPC0 indicates that it

is presently evaluating

the feasibility of

converting Hutsonville #1 and

#2 boilers to oil.

The use

of oil

as

a fuel source would apparently bring the plant into compliance

with the Illinois

air pollution regulations.

CIPC0 then questions

whether Section 2(b)

of the Order

acts as

a limiting factor upon

CIPC0’s operations by insisting that the plant remain on “cold

standby” until January

1,

1974.

The Board Order is not intended

to mandate that

the plant remain on “cold standby”, but only to

insure that

if tue boilers are

to be operated in violation of the

applicable regulations after September

30, 1972,

that they then

be operated only on

a “cold standby” basis.

If CIPC0’s change of

fuel results

in the Hutsonville #1 and #2 boilers coming into

compliance,

there exists no need at all for

a variance.

I,

Christan

L. Moffett,

Clerk of the Pollution Coi~1t~olBoard,

certify that the Board adopted the above Opinion this

c~

of

______________

1972, by
