INTERIM

ORDER

OF THE BOARD

(by J,D,

Duwieiie):

The

record in this proceeding indicates some local problems

with smoke,

fumes,

or odors.

(R,1070,

1075,

1089—1094,

1102—3,

1238-9,

1245,)

However, insufficient information is available to

determine the origin of these odors,

Furthermore, should it be

established that they emanate from the power plant, it is unclear

whether or not the use of Illinois high—sulfur coal aggravates or

reduces the problem.

Therefore,

the Board asks that the partici-

pants,

especially the Petitioner and the Illinois Environmental

Protection Agency (Agency)

supply the following information.

During the one year period prior to,

and during the period

of the Petitioner’s operating permit issued April

20,

1982

and

expiring on January 20,

1983:

1)

How frequently and on which dates did “soot blowing”.

i.e.

tube cleaning, occur at the Tower Plant?

2)

How often and on

which

dates were stack tests

conducted?

3)

What

other changes

in the plant’s daily operations

such

as

an increase

in production,

fuel switch,

etc~,,

or

malfunctions have taken place and on which

dates?

Could they

have

created

odors?

4)

How

many

citizen

complaints

were

received

about

the

plant’s

operations?

5)

Were

these

complaints

forwarded

to

the

Agency?

The

Board

also asks

that

copies

of

these

complaints,

if

any,

be

provided~

The participants are also requested to evaluate whether the

use of Orient

#4 coal

in Boiler No.

8 significantly changes the

plant’s operations and if so,

to

what extent,

Finally,

an

evaluation should be made as to whether these alterations create

or aggravate odor incidences and if so, where the odors emanate

from,

52~385

---

2

The Petitioner is to consider whether a reduction in

the

stack’s diameter by means of a partition would increase exit

velocity. Regardless of odor causation, the cost and feasibility

of partitioning the existing stack for single boiler operation

shall be presented.

The plume rise attributable to increased

stack gas velocity using a partition shall be computed.

Answers to these questions and

the

information requested

should be provided within sixty days of this Order.

If neces-

sary, an additional public hearing on the same may be ordered by

the

Board.

IT IS SO ORDERED.
