ORDER OF THE

BOARD

(by J.

Marlinh

On November 18,

1983 the Board

opened

this Docket for the

purpose

of promulgating

a definition

of

“liquid hazardous waste”

in

order to

facilitate

the direct implementation of Section 22.6

of the Environmental

Protection

Act

(Act),

which

prohibits

the

landfilling of liquid

hazardous

waste

after July

1,

1984.

The

Board solicited proposals

from

the

public.

On February

9~1984

the Board authorized hearings on three proposals,

prepared

by

the

Board staff,

Citizens for a Better Environment

(CBE)

and

the

Environmental Protection

Agency

(Agency)~

Public hearings were

held on April

13 and 23~

1984.

CBE

and the

Agency entered a

joint proposal

as Exhibit

4.

Waste

Management

of

Illinois,

Inc.,

entered an alternative

proposal

as Exhibit

12.

TheHearing Officer set a comment period to

end

May 23,

1984.However, the Board

has

accepted

late comments because of

delays in the filing of the April

23 transcript.

Section 22.6 of the

Act

includes a ban effective July l~

1984.

If this date passed without implementing regulations..

there would be no way to lawfully dispose of some hazardous

wastes.

However~no economic impact study has

yet been prepared.

The

Board finds that the

July

1,

1984 date

constitutes a deadline

for adoption of regulations,

and that the failure

to adopt

implementing regulations

by July

1 would result in a

threat

to

the public health, safety

and

welfare within the

meaning

of

Section 27 of the Act.

The Board will therefore

adopt 35 Ill.

Adm~Code 709 and 729 as emergency rules.

The same

parts will be

proposed for First Notice.

58~549

---

—2—

The

Board notes that emergency

rules

filed pursuant to the

~dministrative Procedure Act can be effective for no longer than

150 days.

If

it. takes

longer than that

to

prepare an economic

impact study and complete the necessary hearings- temporary rules

may

be

adopted

to

bridge

the gap between expiration of the

emergency rules

and

adoption of the permanent rules.

Pursuant to the request of participants at the hearings, the

Hearing Officer is authorized to conduct additional merit

hearings on the First Notice Proposal prior to completion of the

economic impact study.

The Board will consider any evidence

introduced

at these hearings prior to adoption of the temporary

rules.

The Board will

split this Docket into subdockets~ R82-28A

will be utilized for promulgation of the emergency rules; R83-28B

will be used for the temporary and permanent rules.

This Order

will address both subdockets.
