                                    catchments:                              groundwater levels where

                                    b. manages wastewaters so that:

                                    discharged is maintained
                                    between 6.5 and 8.5 to avoid
                                    mobilisation of acid, iron,
                                    aluminium, and metals, and

                                    wastewaters ensures the
                                    flocculation and removal of any

                                    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 trade waste or another
