Current through Register Vol. 48, No. 38, September 20, 2024
a) Construction Quality Assurance (CQA)
Program
1) A CQA program is required for all
surface impoundment, waste pile and landfill units that are required to comply
with Sections
724.321(c) and
(d),
724.351(c) and
(d), and
724.401(c) and
(d). The program must ensure that the
constructed unit meets or exceeds all design criteria and specifications in the
permit. The program must be developed and implemented under the direction of a
CQA officer who is a registered professional engineer.
2) The CQA program must address the following
physical components, where applicable:
A)
Foundations;
B) Dikes;
C) Low-permeability soil liners;
D) Geomembranes (flexible membrane
liners);
E) Leachate collection and
removal systems and leak detection systems; and
F) Final cover systems.
b) Written CQA Plan. The owner or
operator of units subject to the CQA program under subsection (a) must develop
and implement a written CQA plan. The plan must identify steps that will be
used to monitor and document the quality of materials and the condition and
manner of their installation. The CQA plan must include the following:
1) Identification of applicable units, and a
description of how they will be constructed.
2) Identification of key personnel in the
development and implementation of the CQA plan, and CQA officer
qualifications.
3) A description of
inspection and sampling activities for all unit components identified in
subsection (a)(2), including observations and tests that will be used before,
during and after construction to ensure that the construction materials and the
installed unit components meet the design specifications. The description must
cover: Sampling size and locations; frequency of testing; data evaluation
procedures; acceptance and rejection criteria for construction materials; plans
for implementing corrective measures; and data or other information to be
recorded and retained in the operating record under Section
724.173.
c) Contents of Program
1) The CQA program must include observations,
inspections, tests and measurements sufficient to ensure the following:
A) Structural stability and integrity of all
components of the unit identified in subsection (a)(2);
B) Proper construction of all components of
the liners, leachate collection and removal system, leak detection system, and
final cover system, according to permit specifications and good engineering
practices and proper installation of all components (e.g., pipes) according to
design specifications;
C)
Conformity of all materials used with design and other material specifications
under Sections 724.321, 724.351, and 724.401.
2) The CQA program must include test fills
for compacted soil liners, using the same compaction methods as in the full
scale unit, to ensure that the liners are constructed to meet the hydraulic
conductivity requirements of Sections
724.321(c)(1)(A)(ii),
724.351(c)(1)(A)(ii),
or
724.401(c)(1)(A)(ii)
in the field. Compliance with the hydraulic conductivity requirements must be
verified by using in-situ testing on the constructed test fill. The Agency must
accept an alternative demonstration, in lieu of a test fill, where data are
sufficient to show that a constructed soil liner will meet the hydraulic
conductivity requirements of Sections
724.321(c)(1)(A)(ii),
724.351(c)(1)(A)(ii),
or
724.401(c)(1)(A)(ii)
in the field.
d)
Certification. Waste must not be received in a unit subject to Section 724.119
until the owner or operator has submitted to the Agency by certified mail or
hand delivery a certification signed by the CQA officer that the approved CQA
plan has been successfully carried out and that the unit meets the requirements
of Sections
724.321(c) or
(d),
724.351(c) or
(d), or
724.401(c) or
(d); and the procedure in 35 Ill. Adm. Code
703.247(b)
has been completed. Documentation supporting the CQA officer's certification
must be furnished to the Agency upon request.
