R 299.4916 Landfill construction; construction quality assurance program and construction certifications.

Rule 916. (1) A construction quality assurance (CQA) program is required for all new landfill units and lateral extensions of existing units and for the final cover of existing units. The program shall verify that the constructed unit is in compliance with all design criteria and specifications in the construction permit or approved plans. The program shall be developed and implemented under the direction of a CQA officer who is a registered professional engineer. (2) The CQA program shall address all the following physical components, where applicable: (a) Foundations. (b) Dikes. (c) Low-permeability soil liners. (d) Flexible membrane liners. (e) Leachate collection and removal systems and secondary collection systems. (f) Final cover systems. (3) Before construction begins on a unit that is subject to the CQA program under subrule (1) of this rule, the owner or operator shall develop 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 that are identified in subrule (2) of this rule, including the observations and tests that will be used before, during, and after construction to ensure that the construction materials and the installed unit components are in compliance with the design specifications. The description shall cover all of the following: (i) Sampling size and locations. (ii) Frequency of testing data evaluation procedures. (iii) Acceptance and rejection. (iv) Criteria for construction materials. (v) Plans for implementing corrective measures. (4) The CQA program shall include observations, inspections, tests, and measurements that are sufficient to ensure all of the following: (a) The structural stability and integrity of all components of the unit that are identified in subrule (2) of this rule. (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 according to design specifications. (c) Conformity of all materials used with design and other material specifications under this part.
