            Mary River environmental values and water quality objectives



              Environmental               Water type/        Water quality objectives to protect EV
              value                           area           (refer to specified codes and guidelines for full details)
                                         (refer Table 1
                                            and Plan
                                            WQ1381)
              Suitability for          coastal,              No WQOs are provided in this scheduling document for industrial uses.
              industrial use           estuarine and         Water quality requirements for industry vary within and between
                                       freshwaters           industries. The AWQG (2000) do not provide guidelines to protect
                                                             industries, and indicate that industrial water quality requirements need to
                                                             be considered on a case-by-case basis. This EV is usually protected by
                                                             other values, such as the aquatic ecosystem EV.
