      • What are Acid Sulphate Soils?
      • How do they form and where are they found?
      • Why are they potentially a problem?
      • Some case studies – are they present in New Zealand?
      • How can we determine if they’re present?
      • What legislation applies and what guidelines are out there?
      • How can we manage ASS if we find it?


  • James Corbett, Principal Contaminated Land Specialist from Auckland Council, and Greg Beck, Land Contaminated Principal at Cato Bolam Consultants.
    • NES and questions you were too afraid to ask! James’ and Greg’s presentation will cover the key points:
      • Is it broke? (Basic run through of the questions that were asked in the panel discussion on Working with the NESCS at the WasteMINZ conference
      • What can we fix? (Key areas for change e.g. HAIL; P.A. triggers and thresholds; Controlled activities; Application PSI vs. DSI guidance)
      • What’s it going to cost you? (What we, as an industry, need to do to move it on up, e.g. working groups to assist MfE; written guidance; advocate)
