 Editor’s Note—Planning scheme policy for Assessment of Natural Hazards provides advice and guidance for achieving certain
 outcomes of this code, including guidance for the preparation of an ASS investigation report and management plan.

 8.2.1.2              Purpose and overall outcome
 (1)    The purpose of the Acid Sulfate Soils overlay code is to ensure that the generation or release of acid and metal contaminants from
        acid sulfate soils (ASS) does not have adverse effects on the natural environment, built environment, infrastructure or human
        health.
 (2)    The overall outcome of the Acid Sulfate Soils overlay code is that development ensures that the release of acid and associated
        metal contaminants into the environment is avoided by either:
         (a)      not disturbing ASS when excavating or otherwise removing soil or sediment, extracting groundwater or filling land; or
         (b)      treating and, if required, undertaking ongoing management of any disturbed ASS and drainage waters.

  Development:                                                           The disturbance of ASS is avoided by:
  (a)    does not disturb ASS; or                                        (a)   undertaking an ASS investigation and soil analysis
  (b)    is managed to avoid or minimise the release of acid and               according to the National Acid Sulfate Soils Guidance;
         metal contaminants, where disturbance of ASS is                 (b)   not excavating or otherwise removing soil or sediment
         unavoidable.                                                          containing ASS;

                                                                               (ii)   previously saturated ASS being aerated.
