Approved underground water impact reports

Under section 385 of the Water Act 2000 (the Water Act), the chief executive has approved the following underground water impact reports (UWIRs) and final reports. The decision to approve these reports has been made following an assessment of the reports against the requirements of the Water Act to ensure that the modelling, strategies and obligations are appropriate.

Table 1: UWIRs that are in effect

Under the Water Act, a cumulative management area (CMA) may be declared if an area contains two or more resource tenures, including tenures on which coal seam gas and mining activities operate, and where there may be cumulative impacts on groundwater resulting from water extraction by the tenure holders. The UWIR for a CMA is prepared by the Office of Groundwater Impact Assessment, which is an independent office established under Chapter 3A of the Water Act.
