IN THE MATTER OF:

THE JOINT PETITION OF THE CITY

OF PEORIA AND THE ILLINOIS

)

PCB 85—210

ENVIRONMENTAL PROTECTION AGENCY

FOR EXCEPTION OF THE COMBINED

SEWER OVERFLOW REGULATIONS

INTERIM ORDER

ORDER OF THE BOARD

(by J.

D.

Durnelle):

This

is

a joint combined sewer overflow

(CSO)

petition by

the City of Peoria (Peoria)

and the Illinois Environmental

Protection Agency

(Agency).

Peoria’s compliance plan presented

at the hearing

allows for

the discharge of

floatables at eleven downstream CSO discharges

(Exh.

4).

Peoria’s witness

testified that floatables

control

at

these outfalls was rejected because

of cost.

(R.

35).

Exhibit

4

includes discussion of options

for controlling floatables

at

these locations.

Prior

to decision the board would like to have an assessment

and cost estimate

for controlling floatables at these eleven

downstream outfalls,

at least up

to the 25—year flood

stage.

The

feasibility of

using

swirl concentrators for this purpose should

be examined.

In addition, the Board requests comment

upon the impact of

an order

requiring

(a)

a prohibition of any new connections

of

residential downspouts

to sewers carrying sanitary waste,

(b)

that all new buildings have separate sanitary and storm

connections,

and

(c)

that separate storm and sanitary sewers be

constructed

to the extent feasible when streets

are reconstructed

and when area redevelopment occurs.

Such comments shall

be filed with the Board

and the Agency

by Peoria by March

28, 1986.

The Agency may comment on this

material through April

4,

1986.
