Asbestos Disposal Area

The proposal is for the disposal of asbestos waste that will be generated by the Wallerawang Power Station Closure Project. It is estimated that about 7,000 cubic metres of asbestos waste would be generated and that requires a landfill of approximately 11,000 cubic metres of capacity.

The new asbestos disposal area is proposed to be within the Wallerawang Ash Repository site to the south of Kerosene Vale Ash Repository and an access road to Sawyers Swamp Creek Ash Dam. The site is within Lot 5 of DP829137 and is on land owned by EnergyAustralia.

The asbestos disposal area is proposed to have a footprint of up to approximately 1.8 hectares. It would comprise of six parallel 250-metre long trenches, each three metres wide and three metres deep. Each trench would be excavated and filled progressively as the need arises.

The trenches would be excavated progressively and would be filled to a depth of about 2.5 metres with bagged or wrapped asbestos waste. This trench-and-fill method would enable the length of open trench to be matched to the volume of asbestos waste being generated by the Wallerawang Power Station Closure Project at any one time.

The Wallerawang Power Station Closure Project is estimated to take approximately two years to implement with the proposed asbestos disposal area to be operational throughout this period.
