NA – New condition proposed
Prior to the construction of the Upper Mundic Gully Tailings Storage Facility, the environmental authority holder must install and provide to the administering authority the locations of groundwater monitoring bores to monitor groundwater quality at the Upper Mundic Gully Tailings Storage Facility. Table W1 must be updated to include the name and location of the additional monitoring bores that are installed Prior to the construction of the Upper Mundic Gully Tailings Storage Facility, the environmental authority holder must update the existing site wide groundwater model to incorporate the Upper Mundic Gully Tailings Storage Facility.
Provides assurances that the groundwater quality of the project footprint will be monitored prior to construction of the Upper Mundic Gully TSF. Baseline results will be compared against results obtained during TSF operation to determine potential impacts to groundwater Provides assurance that the existing groundwater model will be updated to consider the potential impacts associated with UMG TSF operations and closure. As impact to Grevillea hockingsii can not be avoided, a management plan is proposed to mitigate impacts. Considering the historical disturbance and degraded nature of the project area, including existing ARD contamination in soil, the modified hydrology, and the presence of dense patches of weeds, it is likely that the population of Grevillea hockingsii within the project area will decline without intervention.
