ORDER OF THE BOARD

 (by G.

T.

 Girard):

On June 17,

 1993,

 the Board adopted the final opinion and

order in this proceeding.

 The June 17 order indicated .that

Sections 811.310(c) (5), 811.310(d) (1) (F) and 813.106(b) were to

be deleted from the Board’s rules.

 The adopted rule as published

in the July 30,

 1993,

 Illinois Register at

 17 Ill.Reg.

 12413 and

12409 also indicated that those three subsections were to be

removed from the Board’s regulations.

 However,

 it has come to

the Board’s attention that the copy of the rules filed with the

Secretary of State’s administrative code unit for inclusion in

the Administrative Code did not delete the subsections.

 This was

an inadvertent typographical error which the Board will today

attempt to correct.

Section 5-85 of the Illinois Administrative Procedure Act

allows an agency to request of the Joint Committee on

Administrative Rules an expedited correction if there are errors

which result in discrepancies between adopted rule text and the

text of rule as previously published in the Illinois Register.

(5 ILCS 100/5-85.)

 Clearly, the inadvertent inclusion of

Sections 811.310(c) (5), 811.310(d) (1) (F) and 813.106(b)

 in the

adopted rule creates a discrepancy between the rule as published

in the Illinois Register and as adopted.

 Therefore, the Board

finds that an expedited correction is proper in this proceeding

and will proceed with the correction.

The Board directs the clerk to file with the Joint Committee

on Administrative Rules all necessary documents to proceed with

an expedited correction pursuant to the Illinois Administrative

Procedure

Act.

The

correction

shall

cause

Sections

811.310

and

813.106 to read as follows:

Section

811.310

Landfill

Gas

Monitoring

a)

 This Section applies to all units that dispose

putrescible

wastes.

Location

and

Design

Monitoring

Wells

2

1)

 Gas monitoring devices shall be placed at inter-

vals and elevations within the waste to provide a

representative sampling of the composition and

buildup of gases within the unit.

2)

 Gas monitoring devices shall be placed around the

unit at locations and elevations capable of

detecting migrating gas from the ground surface to

the lowest elevation of the liner system or the

top elevation of the groundwater, whichever is

higher.

3)

 A predictive gas flow model may be utilized to

determine the optimum placement of monitoring

points required for making observations and

tracing the movement of gas.

4)

 Gas monitoring devices shall be constructed from

materials that will not react with or be corroded

by the landfill gas.

5)

 Gas monitoring devices shall be designed and

constructed to measure pressure and allow collec-

tion of a representative sample of gas.

6)

 Gas monitoring devices shall be constructed and

maintained to minimize gas leakage.

7)

 The gas monitoring system shall not interfere with

the operation of the liner,

 leachate collection

system or delay the construction of the final

cover system.

8)

 At least three ambient air monitoring locations

shall be chosen and samples shall be taken no

higher than 0.025 meter

(1

 inch)

 above the ground

 and 30.49m

 (100 feet) downwind from the edge of

the unit or at the property boundary, whichever is

closer to the unit.

c)

 Monitoring Frequency

1)

 All gas monitoring devices, including the ambient

air monitors shall be operated to obtain samples

on a monthly basis for the entire operating period

and for a minimum of five years after closure.

2)

 After a minimum of five years after closure, moni-

toring frequency may be reduced to quarterly

sampling intervals.

3)

 The santpling frequency may be reduced to yearly

3

sampling intervals upon the installation and oper-

ation of a gas collection system equipped with a

mechanical device such as a compressor to withdraw

gas.

4)

 Monitoring shall be continued for a minimum period

of: thirty years after closure at MSWLF units,

except as otherwise provided by subsections

 (c) (5)

and

 (c) (6), below; five years after closure at

landfills, other than

MSWLF

units, which are used

exclusively for disposing of wastes generated at

the site; fifteen years after closure at all other

landfills regulated under this Part.

 Monitoring,

beyond the minimum period, may

 be discontinued if

the following conditions have been met for at

least one year:

A)

 The concentration of methane is less than

 five percent of the lower explosive limit in

air for four consecutive quarters at all

monitoring points outside the unit; and

B)

 Monitoring points within the unit indicate

that methane is no longer being produced in

quantities that would result in migration

from the unit and exceed the standards of

subsection

 (a) (1).

5)

 The Agency may reduce the gas monitoring period at

a MSWLF unit upon a demonstration by the owner or

operator that the reduced period is sufficient to

protect human health and environment.

6)

 The owner or operator of a

MSWLF

unit shall

petition the Board for an adjusted standard in

accordance with Section 811.303,

 if the owner or

operator seeks a reduction of the postclosure care

monitoring period for all of the following

requirements:

i)

 Inspection and maintenance

 (Section

811.111);

ii)

 Leachate collection (Section 811.309);

iii) Gas monitoring (Section 811.310); and

iv)

 Groundwater monitoring (Section

811.319)

BOARD NOTE:

 Changes to subsections

(c)

 are derived from

40 CFR 258.61

 (1992).

4

ci)

 Parameters to be Monitored

1)

 All below ground monitoring devices shall be moni-

tored for the following parameters at each

sampling interval:

A)

 Methane;

B)

 Pressure;

C)

 Nitrogen;

D)

 Oxygen; and

E)

 Carbon dioxide.

2)

 Ambient air monitors shall be sampled for methane

only when the average wind velocity is less than 8

kilometers

 (five miles) per hour at a minimum of

three downwind locations 30.49 meters

 (100 feet)

from the edge of the unit or the property

boundary, whichever is closer to the unit.

3)

 All buildings within a facility shall be monitored

for methane by utilizing continuous detection

devices located at likely points where methane

might enter the building.

Section 813.106

 Permit Appeals

If THE AGENCY REFUSES TO GRANT OR GRANTS WITH CONDITIONS A PERMIT

THE APPLICANT

MAY,

 WITHIN 35 DAYS, PETITION FOR A HEARING BEFORE

 The petition shall be filed,

 and the

proceeding conducted,
