B-3 – Area 3 - Assessment of Environmental Effects 33 6. MANAGEMENT AND MONITORING OF EFFECTS Section 5 of this sub-AEE provides an assessment of the actual and potential effects of the activities in Area 3, which is based on the various technical assessments commissioned by OGNZL. It is noted that many of the technical assessments have recommended the implementation of various measures in order to assist in avoiding, remedying or mitigating potential adverse effects from the activities on the environment. These recommendations have shaped the development of the suite of management and monitoring measures that are proposed as conditions on the resource consents that are being sought by OGNZL. A copy of the proffered consent conditions is provided in Part E of these application documents. The proffered conditions are largely based on existing measures used for the type of activities proposed at OGNZL’s existing activities. These measures have been very effective of managing the actual and potential effects of the activity. They are set out in Table 3 below and include: Limits on the generation of vibration; The preparation of a Dewatering and Settlement Monitoring and Management Plan which will detail how potential effects associated with dewatering and settlement will be managed and monitored. This plan allows mitigation and monitoring measures to be refined and updated over time as best practice evolves, and as additional information on the receiving environment and the effectiveness of the mitigation measures is gathered via monitoring; and A rehabilitation and closure plan secured by rehabilitation and capitalisation bonds. In addition to these management measures, OGNZL proposes to provide further compensation to potentially affected landowners by: Implementing its Amenity Effect Programme which makes six monthly payments to the owners of occupied residences affected by vibration based on the number and level of vibration and number of blast events they experience; and Providing an ex-gratia payment to the registered proprietor of any residence the Wharekirauponga Access Tunnel passes directly beneath which is equal to 5% of the that property’s market value.
