PROPOSED RULE.

 SECOND NOTICE

PROPOSED ORDER OF THE BOARD

 (by 3. Marlin):

On June 29,

 1984 the Board adopted emergency rules

which implemented provisions of Section 22.6 of the Environ-

mental Protection Act and which restrict disposal of liquid

hazardous waste.

 The emergency rules were filed and effective

on July

1984

 (8 Iii. Reg.

 12668 and 12678, July 13,

1984).

 At the same time the Board proposed to adopt the

emergency rules

 as regular rules

(8

 Ill. Reg.

 11997, 12000).

The Board opened Docket R83-28B for the purpose of adopting

the regular rules.

 On July 19,

 1984 the Board adopted a

Final Opinion supporting the emergency rules, and a Proposed

Opinion suPporting the first notice rules.

 On August 30,

1984 the Board conducted an additional public hearing on the

first notice proposal.

 The extended comment period expired

on September 28,

 1984.

 It appears that an economic impact

study and hearings cannot be completed in time for Board

 action prior to expiration of the emergency rules.

The

Board will send the proposal to second notice.

 The Board

has modified the proposal in response to testimony received

at the public hearing and to the written comments.

The

modified text is attached to this

Order.

 Striking and

underlining in 35 Ill. Mm. Code 729 refer to the Board’s

Order of October 25.

 1984 in R81—25.

The Board will adopt a supporting Opinion at a later date.

Because of its length, this Second Notice Order will not

appear in the Board’s Opinion volumes, but will be distributed

to participants.

IT IS SO ORDERED.

Board Member B. Forcade

concurred.

I, Dorothy M.

 Gunn,

 Clerk of the Illinois Pollution

Control Board, hereby certify that

the

above Order was

adopted on the

SUBPART D:

 REVIEW OF WASTESTREAMS

Section 709.401

 Standard for Issuance for Liquid Hazardous

Waste

a)

 Liquids:

 The Agency shall

 issue a wastestream

authorization for the land disposal of

 a liquid

hazardous waste only after the generator has

reasonably demonstrated that,

 considering current

technological feasibility and economic reasonable-

ness,

 the hazardous waste cannot be reasonably

solidified, stabilized or recycled for reuse, nor

incinerated or chemically,

 physically or biologi-

cally treated so as to neutralize the hazardous

waste and render it nonhazardous, and that land

disposal

 is not prohibited or limited by Board

regulations.

b)

 Residuals:

 The Agency shall issue a wastestream

authorization for the land disposal of the residual

from the treatment of a liquid hazardous waste if

and only if the original generator or treater

 demonstrates that the residual meets one of the

standards of 35 Ill. Mm.

 Code 729.310(b), and that

land disposal is not prohibited or limited by

Board regulations.

81-96

c)

 Negative Finding:

 For wastes which are neither a

liquid hazardous waste nor a residual from the

treatment of a liquid hazardous waste, the Agency

may

issue a wastestream authorization upon a

finding that the wastestream is not subject to any

other landfilling prohibition.
