Current through Register Vol. 48, No. 38, September 20, 2024
a) CQA Program
1) A construction quality assurance (CQA)
program is required for all surface impoundment, waste pile and landfill units
that are required to comply with Sections
725.321(a),
725.354,
and
725.401(a).
The program must ensure that the constructed unit meets or exceeds all design
criteria and specifications in this Part. The program must be developed and
implemented under the direction of a CQA officer that 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. Before
construction begins on a unit subject to the CQA program under subsection (a),
the owner or operator must develop 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
725.173.
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 35 Ill. Adm. Code
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 35 Ill. Adm. Code
724.321(c)(1),
724.351(c)(1),
or
724.401(c)(1)
in the field. Compliance with the hydraulic conductivity requirements must be
verified by using in-situ testing on the constructed test fill. The test fill
requirement is waived where data are sufficient to show that a constructed soil
liner meets the hydraulic conductivity requirements of 35 Ill. Adm. Code
724.321(c)(1),
724.351(c)(1),
or
724.401(c)(1)
in the field.
d)
Certification. The owner or operator of units subject to this Section must
submit to the Agency by certified mail or hand delivery, at least 30 days prior
to receiving waste, a certification signed by the CQA officer that the CQA plan
has been successfully carried out and that the unit meets the requirements of
Sections
725.321(a),
725.354, or 725.401(a). The owner or operator may receive waste in the unit
after 30 days from the Agency's receipt of the CQA certification unless the
Agency determines in writing that the construction is not acceptable, or
extends the review period for a maximum of 30 more days, or seeks additional
information from the owner or operator during this period. Documentation
supporting the CQA officer's certification must be furnished to the Agency upon
request.
e) Final Agency
determinations pursuant to this Section are deemed to be permit denials for
purposes of appeal to the Board pursuant to Section 40 of the Environmental
Protection Act.
