Discharges of contaminants from contaminated land shall be managed so that they:
- do not present significant risk1 of chronic or acute toxic effects on 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 that are inconsistent with the water management objectives in Section 3.1.2
- there are no adverse effects on air quality that are inconsistent with air quality objectives in Section 6.1.2
- avoid significant adverse effects on the relationship that tangata whenua as Kaitiaki have with their identified taonga such as ancestral lands, water and waahi tapu
- remedy or mitigate cumulative adverse effects on the relationship that tangata whenua as Kaitiaki have with their identified taonga such as ancestral lands, water and waahi tapu.
Principal Reasons for Adopting the Objective
Waikato Regional Council is responsible for ensuring that the adverse effects of discharges from contaminated land are managed. Objective 5.3.2 has focused Waikato Regional Council on managing the significant risks of adverse effects rather than focusing only on the immediate effects.
Part a) therefore identifies that discharges from contaminated land should not present significant risks of adverse effects on human health, flora or fauna.
Parts b) and c) provide for integrated management of the issues associated with contaminated land by cross-referencing directly to the relevant water and air management objectives in Chapters 3.1 and 6.1.
Parts d) and e) acknowledge the relationship that tangata whenua as Kaitiaki have with the land. When managing contaminated land, care must be taken to ensure that this relationship is not damaged.
