7.3 Surface Water and Wetlands In preparing this application, consideration has been given to guideline ESR/2015/1837 – Application requirements for activities with impacts to water (DETSI, 2024d). DETSI is required to assess the application against the requirements stated in the Environmental Protection Act 1994 , EP Regulation and the EPP Water to meet the environmental objective and performance outcomes described below: Environmental Objective ∕ ‘The activity will be operated in a way that protects environmental values of waters.’ Performance Outcome There is no actual or potential discharge to waters of contaminants that may cause an adverse effect on an environmental value from the operation of the activity . All of the following: ∕ The storage and handling of contaminants will include effective means of secondary containment to prevent or minimise releases to the environment from spillage or leaks. ∕ Contingency measures will prevent or minimise adverse effects on the environment due to the unplanned releases or discharges of contaminants to water. ∕ The activity will be managed so that stormwater contaminated by the activity that may cause an adverse effect on an environmental value will not leave the Project without prior treatment. ∕ The disturbance of any Acid Sulfate Soils, or potential Acid Sulfate Soils, will be managed to prevent or minimise adverse effects on environmental values. ∕ Acid producing rock will be managed to ensure that the production and release of acidic waste is prevented or minimised, including impacts during operation and after the environmental authority has been surrendered. ∕ Any discharge to water or a watercourse or wetland will be managed so that there will be no adverse effects due to the altering of existing flow regimes for water or a water course or wetland. ∕ For a petroleum activity, the activity will be managed in a way that is consistent with the coal seam gas water management policy, including the prioritisation hierarchy for managing and using coal seam gas water and the prioritisation hierarchy for managing saline waste. ∕ The activity will be managed so that adverse effects on environmental values are prevent or minimised. Environmental Objective The activity will be operated in a way that protects the environmental values of groundwater and any associated surface ecological systems. Performance Outcome Both of the following apply: ∕ There will be no direct or indirect release of contaminants to groundwater from the operation of the activity. ∕ There will be no actual or potential adverse effect on groundwater from the operation of the activity. Or, the activity will be managed to prevent or minimise adverse effects on groundwater or any associated surface ecological systems. Some activities involving direct releases to groundwater are prohibited by the EP Regulation. Values No wetlands of international or national importance, or high ecological value wetlands were identified within or proximal to the Project area.
