145 d. Construction Monitoring Inspection Schedule All subsequent amendments to the design shall be supplied to the Waikato Regional Council prior to implementation and following Peer Review. 17 All construction works shall be implemented under the supervision of persons with appropriate and documented experience in the supervision of civil engineering construction works. The Consent Holder shall supply to Waikato Regional Council a full set of as-built plans for the foundations, low permeability liner, underdrainage system, and surface water drainage system of the rock stack development. 18 The Consent Holder shall be responsible for the structural integrity and maintenance of the works associated with the exercise of these consents and for any erosion control and energy dissipation works which become necessary as a consequence of the exercise of these consents. 19 On completion of the foundations, low permeability liner, underdrainage system, and surface water drainage system construction works the Consent Holder shall supply written confirmation to the Waikato Regional Council and the Peer Review Panel stating that the foundations, low permeability liner, underdrainage system, and surface water drainage system works have been constructed in accordance with the design referred to in Condition 16. Thereafter, the facility shall be inspected by the Designer on an annual basis, and a written report on the inspection provided to the Peer Review Panel and copied to Waikato Regional Council within one month of completion of the inspection. Monitoring 20 Throughout the period of mining the Consent Holder shall establish and maintain an inventory of sources and estimated volumes of available inert material. This inventory is to be updated at six monthly intervals and balanced against estimated future demand for inert material. This inventory shall be available upon request by Waikato Regional Council and the Peer Review Panel. In the event a shortfall occurs or is identified in advance, the Consent Holder shall prepare and implement contingency measures to ensure that proper control of geochemically active materials is maintained. A summary of the inventory and details of any measures which have needed to be taken shall be reported annually to Waikato Regional Council. 21 The Consent Holder shall install groundwater quality monitoring bores to detect seepage escaping the underdrainage system, and to determine the representative groundwater quality for shallow and deeper groundwater around the perimeter of land owned by the Consent Holder.
