ILLINOIS POLLUTION CONTROL BOARD

February 19, 1981

IN THE MATTER OF:

)

AMENDMENTS TO CHAPTER 3:

)

R76-21

WATER POLLUTION

)

PROPOSED RULE.

FIRST NOTICE

ORDER OF

THE

BOARD

(by D. Satchell):

On November 23, 1976 the Illinois Institute for Environmental

Quality

(since renamed the Illinois Institute of Natural Resources)

filed a proposal for amendments to Chapter 3:

Water Pollution.

Hearings and the Economic Impact Studies have been completed.

The Board proposes to adopt the language which appears below.

The Clerk is directed to file a notice of proposed rulemaking

with the Secretary of State.

The record will remain open for

comment for forty-five days from the date of publication in the

Illinois Register.

Subpart A:

General Effluent Standards

Rule 400 Preamble

This part prescribes the maximum concentrations of various contam-

inants tha’~which may be discharged to the waters of the State.

Subpart A prescribes standards of general applicability.

Site

specific rules and particular exceptions are found in Subpart B.

C)

Except

as otherwise specifically provided,~proof of violation

of the numerical standards of this Part shall be determined on

the basis of one or more of the following averaging rules:

1)

The average of three or more flow—weighted 24—hour composite

samples taken in a calendar month shall not exceed the pre-

scribed numerical standard.

2)

No

flow-weighted 24—hour composite sample shall exceed

two times the prescribed numerical standard.

3)

No grab sample, whether taken individually or as an alicruot

—

of a composite sample,

shall exceed five times the pre~

scribed numerical standard.

4)

If

a discharge is pursuant to an NPDES permit which does

—

not contain a definition of “flow-weighted 24-hour com-

posite sample”

for a given parameter for which monitoring

is required, then the following rules also apply:

A)

The average of three or more grab samples taken in

a

single day shall not exceed two times the prescribed

numerical standard.

B)

The average of nine or more grab samples taken on

three or more days in a calendar month shall not

exceed the prescribed numerical standard.

d)

If samples are averaged over a given period of time,

all

—

samples available in that time period shall be included in

the average.

e)

Reporting and monitoring requirements are established by way

of permit condition pursuant to Rules 501 and 910(f).

consistent with technological feasibility, economic reason-

6)

The discharger has

a surveillance program with a reasonable

?ion.

When para~raphb)

applies, the Agency may impose an

effluent limitation in the

permit

which allows discharge

of a

concentration of mercury greater than 0.0005 mg/l but not more

than 0.003 mg/l.

Rule 412

New Source Performance Standards

The numerical effluent standards of this Part do not apply under

the following circumstances:

a)

The discharge is authorized by an NPDES permit

b)

The facility from which the discharge results is subject to new

source performance standards promulgated by USEPA pursuant to

the Clean Water Act; and

upon USEPA effluent guidelines and standards representing best

available demonstrated control technology for the constituent

in question.
