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.

Dumelle):

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.
