Earthworks may involve paddock recontouring, or putting in new tracks.
There are two main aspects of earthworks to consider:the loss of soil, and the likelihood of sediments and runoff reaching streams. Under the Fresh Water Plan you do not need a resource consent for the discharge of stormwater from earthworks if:
- You are working in a small area (less than one hectare) o the volume of disturbed material is less than 3000 cubic metres.
- The area is stabilised as soon as possible after the earthworks have been completed.
- The runoff does not contain a lot of silt.
- There are unlikely to be significant adverse effects on the quality of water.
If earthworks extend over a larger area (between one hectare and eight hectares), then they are still permitted as long as the volume is less than 24,000 cubic metres, soil stabilisation is undertaken as soon as practicable, you meet the other requirements listed above, and you are not doing the work during winter (between 1 May and 31 October).
If you cannot meet the requirements or if you are likely to discharge into one of the significant wetland areas listed in the Fresh Water Plan (see Wetlands section), you may be required to apply for a resource consent. The Taranaki Regional Council has produced Guidelines for Earthworks - contact the Council for a copy or for advice on controlling stormwater runoff from earthworks.

You should also check your district council's District Plan - earthworks and excavations near a streambank may need to meet requirements of your local district council.
