This

matter

comes before the Eoo.rd on the petition for

variance

filed

by the City cf Carlyle (City).

The

City

seeks

variance

from the 1

mq/.

total suspended solids

(TSS)

limitation

of

Rule

408(a) of Chapter

3~

Water Do:tlution

(which

limitation

has

been incorporated into

~ NPLED permit)

until

August

1,

1985.

On May

18,

1982 the Illinois Lnvfronmental Protection

Agency

(Agency)

moved to

fi:Le its

co~mendeticnin support of

variance

instanter,

which

motion

is hereby granted.

Hearing

waived

and

none

has been held,

The subject

of this

va~iance

ic the drinking water

treatment

plant

(WTP)

of

the City of

Carlyle,

Clinton County.

The WTP

supplies the water

needs

of the Dity,

the

Village of Beckmeyer,

and the Clinton

County East and Carlyle Southwest

Public Water

supply Districts as

well as recreational and administrative

facilities of the Illinois Department of Conservation

and the

U.S. Army

Corps of 1~gineers.

Raw water from the

Kaskaskia

River is treated

with lime,

airm,

fluoride

and chlorine.

The

lime and alum,

in

combination

with the

turbidity

present in the

raw water,

produce

a

water treatment sludge which is

discharged

into the Kaskaskia

River approximately one mile downstream

from

the Carlyle

Lake

Spillway~ The Wrir ioo~tedon

a reach of the

River is heavily

fishecL

The discharge contains

TSS in violation

of the Board~sstandard~.

Discharge occurs from two distinct sources

in the plant.

One

is filter backwash

water ranging in volume from

4850

to

14,500

gallons, which

is

discharged

either daly,

or

three

out

of every

5 days, depending

on

the

turbidity of

the

raw

water.

The back-

wash TSS concentrations

range

from 60 to

780

mg/I,

averaging

378

mg/i over the

last three years~

The other source

of

discharge

is the settling

tanks during clean:ing, which generally

occurs

six times

a

yearn

The high TSS level has been reported

as 11,000

mg/i, with a

discharge volume of abunt 190,000 gallons.
