Detailed Site Investigation (DSI)

  After the Preliminary Site Investigation (PSI) how do I know if any HAIL activities are/have been carried out out my site?

If there is or has been a HAIL on your site a Detailed Site Investigation (DSI) is likely to be required to determine the risk level and the type of resource consent required (Unless the activity complies with permitted activity conditions under regulation 8).

The DSI involves intrusive techniques to collect field data and soil samples for laboratory testing to determine the concentrations of contaminants of concern. Concentrations of contaminants are compared to the applicable standard to determine the risk level. The DSI is designed based on the findings of the PSI.

The NES CS requires that a DSI be submitted with the consent application for it to be considered controlled or restricted discretionary.
