B-6 – Area 6 – Assessment of Environmental Effects 110 7.6.1.9 Discharges onto or into lands Objective 5.2.2 of the WRP relates to the discharges of wastes and hazardous substances onto or into land. It acknowledges that discharges onto, or into, land are a necessary facet of resource use in the Waikato Region and, subject to environmental standards, should be allowed to occur. In that context, it seeks that these discharges be undertaken in a manner that: Does not contaminate soil to levels that present significant risks to human health or the wider environment;175 Does not have adverse effects on aquatic habitats, surface water quality or ground water quality that are inconsistent with the Water Management objectives in Section 3.1.2;176 Does not have adverse effects related to particulate matter, odour or hazardous substances that are inconsistent with the Air Quality objectives in Section 6.1.2;177 Is not inconsistent with the objectives in Section 5.1.2;178 and Avoids significant adverse effects, and remedies or mitigates cumulative adverse effects, on the relationship that tangata whenua as kaitiaki have with their taonga such as ancestral lands, water and waahi tapu.179 Policy 2 of Section 5.2.3 follows a similar theme as the objective and seeks that discharges of contaminants to land be undertaken in a manner that avoids, where practicable, adverse effects on a range of values. Where the avoidance of adverse effects is not possible, the policy seeks that they be remedied or mitigated. Of particular note with respect to discharges to land within Area 6: As described in Section 5.6 of this AEE, runoff and seepage from the NRS will be intercepted by a comprehensive underdrainage system and collection ponds which will be pumped to the WTP for treatment prior to discharge into the Ohinemuri River. Accordingly, no adverse effects are anticipated to arise with respect to aquatic habitats and water quality that are inconsistent with the objectives in section 3.1.2;180 Construction activities within Area 6 will be undertaken in accordance with an Air Quality Management Plan, as described in Section 5.10 of this AEE. Accordingly, no 175 Objective 5.2.2(a), Section 5.2, Waikato Regional Plan. 176 Objective 5.2.2(b), Section 5.2, Waikato Regional Plan. 177 Objective 5.2.2(c), Section 5.2, Waikato Regional Plan. 178 Objective 5.2.2(d), Section 5.2, Waikato Regional Plan. 179 Objective 5.2.2(e), Section 5.2, Waikato Regional Plan. 180 Objective 3.5.2(a), Section 3.5, Waikato Regional Plan.
