Important information for all subdivisions and changes of land use, especially rural subdivisions
The National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health relates to land which is actually or potentially contaminated either from an activity or industry on the Hazardous Activities or Industries List (HAIL) or where a HAIL activity is likely to have been undertaken on that land. Please visit the Ministry of Environment website for more information.
If your site is identified as a site where a HAIL activity may have taken place (on Environment Canterbury's Listed Land Use Register), then you can download a guidance form to assess whether your planned activity is at risk of disturbing the soil.
If you would like to find out whether your site is identified as a HAIL site, fill in this form and submit it to Council with your PIM and building & planning assessments for building consents or land use consents.
