                              The Act requires that appropriate action be taken to report that environmental harm is occurring or has
                              the potential to occur, unless the harm is authorised under an environmental protection policy, an
                              environmental management program, a development approval, or an environmental protection order.
                              This is known as the “Duty to Notify”. Failure to fulfil this duty is an offence and may result in prosecution.
                      1.4     DMP objectives
                              The objectives of the DMP are to:
                                  Describe the dewatering methodology, groundwater treatment, monitoring and reporting
                                   procedures to be employed at the site during dewatering activities.
                                  Provide effective management procedures to prevent environmental harm resulting from the
                                   discharge of extracted groundwater from the site.
                      1.5     Scope of work
                              To achieve the investigation objectives, the following scope of work was undertaken:
                                  A desktop study including:
                                   1. Review of the development proposal and proposed shoring/dewatering designs (where
