49A Acid sulfate soils

Development on land identified as Class 1, 2, 3, 4 or 5 on the Acid Sulfate Soils Hazard Map is to be carried out in a manner that manages any disturbance to acid sulfate soils so as to minimise impacts on natural waterbodies and wetlands, and on agriculture, fishing, aquaculture, urban activities and infrastructure.

In particular—

Consent must not be granted to proposed works outlined below for the Class of land concerned, that disturb more than one tonne of soil or that are likely to lower the watertable, unless the consent authority has considered an acid sulfate soils management plan prepared in accordance with the Acid Sulfate Soils Assessment Guidelines. However, an acid sulfate soils management plan is not required where a preliminary assessment of the proposed works undertaken in accordance with these guidelines indicates that the proposed works need not be carried out pursuant to an acid sulfate soils management plan, and a copy of the assessment has been given to the Council.

| Class of land as shown on Acid Sulfate Soils Hazard Map | Works | | 1 | Any works | | 2 | Works below natural ground surfaceWorks by which the watertable is likely to be lowered | | 3 | Works beyond 1 metre below natural ground surfaceWorks by which the watertable is likely to be lowered beyond 1 metre below natural ground surface | | 4 | Works beyond 2 metres below natural ground surfaceWorks by which the watertable is likely to be lowered beyond 2 metres below natural ground surface | | 5 | Works on land below the 10 metre AHD contour and within 500 metres of adjacent Class 1, 2, 3 or 4 land which are likely to lower the watertable below 1 metre AHD on adjacent Class 1, 2, 3 or 4 land |

Note—

The works may occur in the carrying out of agriculture, the construction or maintenance of drains, extractive industries, dredging, the construction of artificial waterbodies (including canals, dams and detention basins), foundations, flood mitigation works or other works that are likely to lower the watertable.
