Site rehabilitation and restoration
Liddell Ash Dam capping was slightly less than previous reporting period due to extended periods of wet weather. Ravensworth Ash Deposition to Void 5 was consistent with the previous reporting period.
Subsurface decommissioning of all 144 gas wells has been completed. The final three well surface locations (which comprised a total of 12 gas wells) are now under surface rehabilitation before being approved by government regulators and returned to their respective landowners. One further site has been fully rehabilitated and inspected by the govenment regulator and returned to the landowner, waiting on formal written approval from the government regulators.
