Current through Register Vol. 50, No. 9, 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 LAC 33:V.2903.J and K, 2303.C and D, and
2503.L and M. The program must ensure that the constructed units meet or exceed
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 LAC 33:V.1504.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:
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 LAC
33:V.1504.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:
a. sampling size and
locations;
b. frequency of
testing;
c. data evaluation
procedures;
d. acceptance and
rejection criteria for construction materials;
e. plans for implementing corrective
measures; and
f. data or other
information to be recorded and retained in the operating record under LAC
33:V.1529.
C.
Contents of Program
1. The CQA program must
include observations, inspections, tests, and measurements sufficient to
ensure:
a. structural stability and integrity
of all components of the unit identified in LAC 33:V.1504.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; and
c.
conformity of all materials used with design and other material specifications
under LAC 33:V.2303, 2503, and 2903.
2. The CQA program shall 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 LAC 33:V.2303.C.1.b, 2503.L.1.b, and
2903.J.1.b in the field. Compliance with the hydraulic conductivity
requirements must be verified by using in situ testing on the constructed test
fill. The administrative authority may 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 LAC 33:V.2303.C.1.b,
2503.L.1.b, and 2903.J.1.b in the field.
D. Certification. Waste shall not be received
in a unit subject to this Section until the owner or operator has submitted to
the Office of Environmental Services, by certified mail or hand delivery, a
certification signed by the CQA officer that the approved CQA plan has been
successfully carried out, that the unit meets the requirements of LAC
33:V.2903.J or K, 2303.C or D, or 2503.L or M, and the procedure in LAC
33:V.309.L.3.b has been completed. Documentation supporting the CQA officer's
certification must be furnished to the administrative authority upon
request.
