Haw. Code R. § 11-265-19 - 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 subsection 11-265-221(a), section 11-265-254,
and subsection 11-265-301(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:
(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.
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:
(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
11-265-73.
(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 paragraphs 11-264-221(c)(1),
11-264-251(c) (1), and 11-264-301(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 paragraphs 11-264-221(c)(1), 11-264-254(c)(1), and
11-264-301(c)(1) in the field.
(d) Certification. The owner or operator of
units subject to section 11-265-19 must submit to the director by certified
mail or hand delivery, at least thirty 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 subsection
11-265-221(a), section 11-265-254, or subsection 11-265-301(a). The owner or
operator may receive waste in the unit after thirty days from the director's
receipt of the CQA certification unless the director determines in writing that
the construction is not acceptable, or extends the review period for a maximum
of thirty 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 director upon request.
