                      a.      a pH range of 6.5-8.5 pH units;
                      b.      50mg/L maximum total suspended solids concentration;
                      c.      0.3mg/L maximum total iron concentration;

                      throughout the duration of the excavation phase of the development. The verification testing
                      must be undertaken by a qualified person* using the SPOCAS or Chromium Reducible
                      Sulphur testing suite, and the results must be submitted to Council for appraisal.
                      Damage to Services and Assets
