Cougar Sand Supplies propose to extend their existing sand and limestone quarry over a period of 10 – 15 years. The quarry is located approximately 7.7 kilometres northeast of the Preston Beach townsite in the Shire of Waroona.

The proposal is adjacent to the Myalup State Forest and is within an exclusion area under State Planning Policy 2.4 - Planning for Basic Raw Materials.

Infrastructure from the existing quarry including a bore, access roads and a mobile crushing and screening plant will be used to support the quarry extension.

The proposal would include a total disturbance of 21.53 hectares. Excavations will maintain a 2 metre distance to the water table. 

At closure, the quarry will be contoured and rehabilitated to return the previously existing vegetation communities
