                                                    b. manages wastewaters so that
                                                    (i) the pH of any wastewater discharged is
                                                    maintained between 6.5 and 8.5 to avoid
                                                    mobilisation of acid, iron, aluminium, and
                                                    metals, and
                                                    (ii) holding times of neutralised wastewaters
                                                    ensures the flocculation and removal of any
                                                    dissolved iron prior to release, and
                                                    (iii) visible iron floc is not present in any
                                                    discharge, and
                                                    (iv) precipitated iron floc is contained and
                                                    disposed of, and
                                                    (v) wastewater and precipitates that cannot be
                                                    contained and treated for discharge on site are
                                                    removed and disposed of through tradewaste
                                                    or another lawful method.
