Stage 1
Stage 2
Low
Seepage may reach area of low potential GDEs along Dee River, however impact is expected to be low based on elevation of creek bed and distance away. Additionally, low and moderate potential GDEs are located respectively west and north of the TSF, however, this is upgradient of the TSF and with the direction of seepage towards the south-east, no significant impacts are expected.
General environmental harm
Same as Stage 1.
Low
No bores used for water supply have been identified in the vicinity of the TSF or in the direction of the groundwater flow. Therefore, loss of agriculture and/or stock is not expected.
