Haw. Code R. § 11-264-19 - Construction quality assurance program
(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 subsections 11-264-221(c), 11-264-221(d),
11-264-251(c), 11-264-251(d), 11-264-301(c) and 11-264-301(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:
(i) Foundations;
(ii) Dikes;
(iii) Low-permeability soil liners;
(iv) Geomembranes (flexible membrane
liners);
(v) Leachate collection
and removal systems and leak detection systems; and
(vi) 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:
(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
paragraph (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
11-264-73.
(c) Contents
of program.
(1) The CQA program must include
observations, inspections, tests, and measurements sufficient to ensure:
(i) Structural stability and integrity of all
components of the unit identified in paragraph (a)(2);
(ii) 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;
(iii)
Conformity of all materials used with design and other material specifications
under sections 11-264-221, 11-264-251, and 11-264-301.
(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 clauses 11-264-221(c)(1)(i)(B),
11-264-251(c)(1)(i)(B), and 11-264-301(c)(1)(i)(B) in the field. Compliance
with the hydraulic conductivity requirements must be verified by using in-situ
testing on the constructed test fill. The director 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
clauses 11-264-221(c)(1)(i)(B), 11-264-251 -(c)(1)(i)(B), and
11-264-301(c)(1)(i)(B) in the field.
(d) Certification. Waste shall not be
received in a unit subject to section 11-264-19 until the owner or operator has
submitted to the director 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 subsection
11-264-221(c) or (d), 11-264-251(c) or (d), or 11-264-301(c) or (d); and the
procedure in paragraph 11-270-30(l)(2)(ii) has been completed. Documentation
supporting the CQA officer's certification must be furnished to the director
upon request.
