Appendix C: Site Classification Categories

The three categories are described below in a format that local authorities may wish to adapt and provide to members of the public or interested parties (for example, attaching to letters from Appendix B).

Land-use information

This category is for sites for which some information is available about the land-use history, or the presence or absence of hazardous substances, or both. One or more of the following descriptions may relate to a specific site.

  • The relevant land-use history has not been confirmed. The site has been reported as one that appears on the Hazardous Activities and Industries List, but the reported use has not been confirmed.
  • The land-use history has been confirmed. The site has been confirmed as one that appears on the Hazardous Activities and Industries List.
  • The site has been investigated. Investigations indicate that there are no hazardous substances present at the site. The site was associated with an activity or industry that uses, stores or disposes of hazardous substances, but investigations indicate that hazardous substances are at background concentrations or below.
  • The site has been investigated. Investigations indicate that there are no hazardous substances present at the site. The site previously had hazardous substances present, but the site has been remediated to reduce concentrations of those hazardous substances to background concentrations or below.
  • The site has been investigated. Investigations indicate that there are hazardous substances present at the site, but indicate that any adverse effects or risks to people and the environment are considered to be so low as to be acceptable.
  • The site has been investigated. Investigations indicate that there are hazardous substances present at the site, but indicate that any adverse effects or risks to people and the environment are managed.
  • The site has been partially investigated. Investigations indicate that there are hazardous substances present at the site; however, there is insufficient information to quantify any adverse effects or risks to people or the environment.

Contaminated land

This category is for sites that fit within the definition of contaminated land in the Resource Management Act 1991. The site has been investigated. There are hazardous substances present on the site that have, or are reasonably likely to have, significant adverse effects on the environment.

Error

This category is for sites that have been entered on the register in error. Information shows that this site has never been associated with any of the specific activities or industries on the Hazardous Activities and Industries List.
