Remediation Action Plans (RAP)

A Remediation Action Plan (RAP) is a document used to establish the remedial and management methodology required to mitigate the risk posed by contaminants. A RAP is required if the DSI identifies concentrations of contaminants above human health guideline values. This remedial action may include:

• Removing the contaminated soil or reducing the contaminant concentrations in the soil

• Interrupting the exposure pathway, including barriers such as soil caps, concrete floors, or paved surfaces to prevent contact with soil, or membranes or ventilation systems protecting against vapour migration

• Removal of receptors or modifying their behaviour.

Site Management Plan

A Site Management Plan (SMP) is used to ensure that when undertaking the works on contaminated sites that potential risks to the following are adequately managed:

• The health of workers

• The on-site environment

• The off-site environment (including the health of neighbouring site users, where relevant). These plans are often a requirement of resource consent.

There may be considerable overlap between RAPs and SMPs. In less complex cases all the requirements of an SMP could be included in a RAP, while in other cases, some of the normal contents of a RAP could be included in an SMP
