Current through August 26, 2024
(1) CQA PROGRAM.
(a) A construction quality assurance (CQA)
program is required for all surface impoundment, waste pile and landfill units
that are required to comply with ss.
NR 664.0221(3)
and (4), and 664.0251(3) (4) and
and 664.0301(3) (4). The program shall ensure that the constructed unit meets
or exceeds all design criteria and specifications in the approved feasibility
and plan of operation report. The program shall be developed and implemented
under the direction of a CQA officer who is a registered professional
engineer.
(b) The CQA program shall
address all of the following physical components, where applicable:
1. Foundations.
2. Dikes.
3. Low-permeability soil liners.
4. Geomembranes (flexible membrane
liners).
5. Leachate collection and
removal systems and leak detection systems.
6. Final cover systems.
(2) WRITTEN CQA PLAN. The owner or
operator of units subject to the CQA program under sub. (1) shall develop and
implement a written CQA plan. The plan shall 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 shall include all of the following:
(a) Identification of applicable units, and a
description of how they will be constructed.
(b) Identification of key personnel in the
development and implementation of the CQA plan, and CQA officer
qualifications.
(c) A description
of inspection and sampling activities for all unit components identified in
sub. (1) (b), 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 shall
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 s.
NR 664.0073.
(3) CONTENTS OF
PROGRAM.
(a) The CQA program shall include
observations, inspections, tests and measurements sufficient to ensure all of
the following:
1. Structural stability and
integrity of all components of the unit identified in sub. (1) (b).
2. Proper construction of all components of
the liners, leachate collection and removal system, leak detection system and
final cover system, according to approved feasibility and plan of operation
report specifications and good engineering practices, and proper installation
of all components (e.g., pipes) according to design specifications.
3. Conformity of all materials used with
design and other material specifications under ss.
NR 664.0221, 664.0251 and 664.0301.
(b) 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 ss.
NR 664.0221(3)
(a) 1. b., 664.0251 (3) (a) 1. b. and
664.0301 (3) (a) 1. b. in the field. Compliance with the hydraulic conductivity
requirements shall be verified by using in-situ testing on the constructed test
fill. The department 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 ss.
NR 664.0221(3)
(a) 1. b., 664.0251 (3) (a) 1. b. and
664.0301 (3) (a) 1. b. in the field.
(4) CERTIFICATION. Waste may not be received
in a unit subject to s. NR 664.0019 until the owner or operator has submitted
to the department 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 s.
NR 664.0221(3)
or (4), or 664.0251(3) (4) or
or 664.0301(3) (4); and the procedure in s.
NR 670.030(12) (b) 2. has been
completed. Documentation supporting the CQA officer's certification shall be
furnished to the department upon request. The department may choose to perform
a site inspection after reviewing the CQA documentation. An inspection by the
department or the submittal of additional information is subject to the fees
stated in ch. NR 670 Appendix II.
