INTERIM ORDER OF THE BOARD

(by J.D.

Dumelle):

This matter comes before the Board

upon

a December

30, 1985,

joint petition filed by the City of Watseka (Watseka)

and

the

Illinois Environmental Protection Agency (Agency)

seeking

an

exception

to

35 Ill. Adm. Code 306.305(a)

and

(b)

of

the Board’s

combined sewer

overflow (CSO)

regulations.

A public

hearing was

held on March

25,

1986r

in Watseka.

The Board received

additional information from the petitioners on August

8, 1986.

The Board

has reviewed the

record

in this proceeding

including the additional information

filed on August

8,

1986 and

requests that Watseka and the Agency answer each

of the following

questions:

1.

The Board notes that the proposed CSC—related

improvements are

to be constructed

in a phased approach

over approximately

a twenty year period.

Would

the

Agency and Watseka provide the Board with an approximate

cost—breakdown of the CSO—related construction in each

phase of the proposal and the user charge component

attributable

to these

improvements?

2.

Referring

to the additional

information submitted on

August

8,

1986,

the Board

notes that

a Step

I

C-rant was

referenced.

Would

the Agency and Watseka be more

specific

on the amount of grant monies received and what

the monies were used

for?

3.

Also,

referring

to the August

8,

1986 submission,

the

Board

notes that

a revolving loan program was

referenced.

Would

the Agency and Watseka provide more

specifics on this program and provide

an estimate of the

amount of money

to be

saved by Watseka by the CSO—aspect

of this program?

4.

Section 306.361(b)

of the Board’s water pollution

regulations provide

that “where

a minimal

impact

exception justification cannot be

established

...,

or

74-284

---

—2—

where an exception will include modification of

otherwise applicable water quality standards,

an

exception justification shall

include” various

evaluations

including stream sediment analyses,

biological surveys and

a stream chemical analysis.

Is

the Agency and Watseka asserting that the CSO—related

impacts on the Iroquois River

and Sugar

Creek are

minimal?

if

so, please explain

in detail; or,

is

it a

situation under 306.361(d)

where the practicalities of

the situation are such that further evaluations

of the

water quality impacts of Watseka’s CSOs on the receiving

streams are too expensive

in relation

to the relevancy

of the data

to be obtained even though such impacts may

not be minimal?

if

so, please explain

in detail.

This information

shall

be submitted

to the Board within

sixty

(60)

days of the date of this Order.

IT

IS

SC ORDERED.

I,

Dorothy N.

Gunn, Clerk of the Illinois Pollution Control

Board, hereby certify that the above Interim Order was adopted on

the

N. 5~unn, Clerk

Illinois Pollution Control
