Section 66264.19 - Construction Quality Assurance Program(a) Construction Quality Assurance Program (CQA): (1) A CQA program is required for all surface impoundment, waste pile, and landfill units that are required to comply with sections 66264.221(c) and (f), 66264.251(c) and (l), and 66264.301(c) and (d). The program shall ensure that the constructed unit meets or exceeds all design criteria and specifications in the permit. The program shall be developed and implemented under the direction of a CQA officer who is a California State registered professional Civil engineer.(2) The CQA program shall address the following physical components, where applicable: (C) Low-permeability soil liners;(D) Geomembranes (flexible membrane liners);(E) Leachate collection and removal systems and leak detection systems; and(b) Written CQA plan. The owner or operator of units subject to the CQA program under subsection (a) of this section 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: (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 subsection (a)(2) of this section, 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 section 66264.73.(c) Contents of program. (1) The CQA program shall include observations, inspections, tests, and measurements sufficient to ensure: (A) Structural stability and integrity of all components of the unit identified in subsection (a)(2) of this section;(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;(C) Conformity of all materials used with design and other material specifications under sections 66264.221, 66264.251, and 66264.301.(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 sections 66264.221(c)(1)(A)2., 66264.251(c)(1)(A)2., and 66264.301(c)(1)(A)2. 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 sections 66264.221(c)(1)(A)2., 66264.251(c)(1)(A)2., and 66264.301(c)(1)(A)2. in the field.(d) Certification. Waste shall not be received in a unit subject to section 66264.19 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 sections 66264.221(c) or (f), 66264.251(c) or (l), or 66264.301(c) or (d); and the procedure in section 66270.30 (l)(2)(B) of this chapter has been completed. Documentation supporting the CQA officer's certification shall be furnished to the Department upon request.Cal. Code Regs. Tit. 22, § 66264.19
