                               sediment identified as containing acid sulfate      for operational works. A condition may be imposed to
                               soils;                                              this effect.
                               b) not permanently or temporarily extracting
                               groundwater that results in the aeration of
                               previously saturated acid sulfate soils; and
                               c) not undertaking filling that results in actual
                               acid sulfate soils being moved below the
                               watertable or previously saturated acid sulfate
                               soils being aerated;

                               S22.2 The disturbance of acid sulfate soils
                               avoids the release of acid or associated metal
                               contaminants by—
                               a) neutralising existing acidity and preventing
                               the generation of acid and associated metal
                               contaminants; and
                               b) preventing the release of surface or
                               groundwater flows containing acid or associated
                               metal contaminants into the environment.
