B-2 – Area 2 - Assessment of Environmental Effects 110 Erosion and sediment control plans, as set out in the Southern Skies (2022) report, will be implemented during construction of the various facilities located within Area 2 to ensure sedimentation and erosion is minimised. 73 Soil moisture conditions in the regolith soils and terrace deposits are not expected to change as a consequence of dewatering of deeper rocks. The effects of the Willows Farm Access Tunnel dewatering soil properties and associated plant growth is therefore less than minor.74 Measures are being implemented to minimise the potential leaching and runoff of contaminants from the WRS and the SFA into groundwater, surface water and surrounding land. These measures will all minimise the potential for soil contamination arising from activities occurring within Area 2. 75 In light of the above, discharges of contaminants from contaminated land within the site will therefore be managed so they do not present significant risk to human health, flora or fauna due to the contamination of soil and ground or surface water, do not have adverse effects on water quality or aquatic ecosystems, or do not generate adverse effects on air quality that are inconsistent with air quality objectives. As previously noted, OGNZL continues to work with tangata whenua regarding cultural effects and how the project can best accommodate and provide for their relationship with identified taonga. This is considered further in Section 5 of the Overarching AEE. 7.5.1.10 Overall Conclusion Overall, it is concluded that the activities proposed within Area 2 can be undertaken in a manner that enables the objectives and policies of the RPS identified above to continue to be met. 7.6 REGIONAL AND DISTRICT PLANS 7.6.1 Waikato Regional Plan The WRP contains objectives, policies, methods and rules relating to the management of natural and physical resources of the Waikato Region. The WRP addresses the following topics of relevance to Area 2: Water – including provisions which address recent national policy direction, water takes, discharges to water, and the damming and diversion of water; 73 Policy 14.1(a), Waikato Regional Policy Statement. 74 Policy 14.1(b), Waikato Regional Policy Statement. 75 Policy 14.3, Waikato Regional Policy Statement.
