B-6 – Area 6 – Assessment of Environmental Effects 112 Area 6 has historically been used and occupied by HAIL activities, as detailed the WWLA (2022) report. All soil disturbance activities undertaken within the identified HAIL areas will be managed in accordance with an SMP as recommended by WWLA (2022). As set out in the WWLA (2022) report, with the SMP in place, it is anticipated that the potential risk to human health and the environment will be appropriately managed in accordance with this objective. On closure of the mine, Area 6 will be rehabilitated in line with the closure. As described in Section 6, this land will be reverted to pastoral use. Confirmation of the appropriate future land use activities enabled on the site will be informed however, by future monitoring and site investigations on site. 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, 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. 7.6.1.11 Air Quality There are three objectives in Section 6.1.2 of the WRP relating to the management of air quality. They seek: the significant characteristics of air quality are either protected, enhanced or maintained;190 no significant adverse effects from individual site sources on the characteristics of air quality beyond the property boundary;191 and the management of the cumulative effects of discharges on ambient air quality.192 The relevant policies direct that the effects of air discharges be managed, having particular regard to the effects on ambient air quality guidelines, human health, the identified values of tangata whenua as kaitiaki, and any potential cumulative effects. 193 Recognition is also given to the positive benefits to people and communities arising from activities that affect air quality (whilst ensuring that air quality resources are protected and adverse effects 190 Objective 1, Section 6.1.2, Waikato Regional Plan. 191 Objective 2, Section 6.1.2, Waikato Regional Plan. 192 Objective 3, Section 6.1.2, Waikato Regional Plan. 193 Policy 2, Section 6.1.3, Waikato Regional Plan.
