Section 814.702 - Applicable Standards
Universal Citation: 35 IL Admin Code ยง 814.702
Current through Register Vol. 48, No. 38, September 20, 2024
a) All of the requirements for new units described in 35 Ill. Adm. Code 817 shall apply to units regulated under this Subpart, except the following:
1) The location standards in 35 Ill. Adm.
Code
817.402(a), (c) and
(d);
2) The foundation and mass stability analysis
standards in 35 Ill. Adm. Code
817.404
and
817.405;
3) The final cover requirements of 35 Ill.
Adm. Code
817.407
shall not apply to units or parts of units closed, covered, and vegetated prior
to August 1, 1994;
4) The liner and
leachate drainage and collection requirements of 35 Ill. Adm. Code
817.406,
817.407, and 817.408;
5) The
hydrogeological site investigation requirements of 35 Ill. Adm. Code
817.411;
6) The groundwater impact assessment
standards of 35 Ill. Adm. Code
817.413;
7) The groundwater monitoring program
requirements of 35 Ill. Adm. Code
817.414(c);
and
8) The groundwater quality
standards of 35 Ill. Adm. Code
817.416(a),
(b), and (c).
b) The following standards shall apply to units regulated under this Subpart:
1) No new
units shall be opened and an existing unit may not expand beyond the area
included in a permit prior to August 1, 1994 or, in the case of permit exempt
facilities, beyond the area needed for landfilling to continue until closure is
initiated;
2) After August 1, 1994,
the unit may continue to accept special waste under permits existing prior to
August 1, 1994 and may renew those permits as necessary. However, the unit may
apply for supplemental waste stream permits only if the following conditions
are met:
A) The additional waste stream
composition is similar to or compatible with the wastes previously disposed of
in the unit; and
B) The waste
stream leaching characteristics determined in accordance with 35 Ill. Adm. Code
817.103
meets the maximum allowable leaching concentrations for low risk wastes
specified at 35 Ill. Adm. Code
817.106.
3) Groundwater Standards. A unit
shall not contaminate a source of drinking water at the compliance boundary,
defined as any point on the edge of the unit at or below the ground surface. At
any point on the compliance boundary, the concentration of constituents shall
not exceed the applicable groundwater quality standards of 35 Ill. Adm. Code
Part 620. The Board may provide for a zone of attenuation and adjust the
compliance boundary in accordance with Section 28.1 of the Act and the
procedures of 35 Ill. Adm. Code 106.Subpart G upon petition demonstration by
the operator that the alternative compliance boundary will not result in
contamination of groundwater which may be needed or used for human consumption.
In reviewing such petitions, the Board will consider the following factors:
A) The hydrogeological characteristics of the
unit and surrounding land, including any natural attenuation and dilution
characteristics of the aquifer;
B)
The volume and physical and chemical characteristics of the leachate;
C) The quantity, quality, and direction of
flow of groundwater underlying the facility;
D) The proximity and withdrawal rates of
groundwater users;
E) The
availability of alternative drinking water supplies;
F) The existing quality of the groundwater,
including other sources of contamination and their cumulative impacts on the
groundwater;
G) Public health,
safety, and welfare effects; and
H)
In no case shall the zone of compliance extend beyond the facility property
line or beyond the annual high water mark of any navigable surface
water.
4) Calculation of
the Design Period. For the purposes of calculating financial assurance, the
design period shall be calculated as follows:
A) The design period shall be no less than
five years; and
B) The postclosure
care period shall be extended by three years for each year the unit is expected
to be in operation up to the applicable design period required by 35 Ill. Adm.
Code 817. (For example, an existing unit with an expected life of three years
after September 18, 1990 would be required to provide financial assurance for
nine years of postclosure care, 9 = 3 x 3.)
