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.4462.A, 4476, and 4512.A. 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. Before
construction begins on a unit subject to the CQA program under LAC 33:V.4320.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:
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;
and
3. a description of inspection
and sampling activities for all unit components identified in LAC
33:V.4320.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 LAC 33:V.4357.
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.4320.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, 2503.L.1, and
2903.J.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 LAC
33:V.2303.C.1, 2503.L.1, and 2903.J.1 in the field.
D. Certification. The owner or operator of
units subject to this Section must submit to the Office of Environmental
Services, 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
LAC 33:V.4462.A, 4476, or 4512.A. The owner or operator may receive waste in
the unit after 30 days from the administrative authority's receipt of the CQA
certification unless the administrative authority 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 administrative authority upon request.
