This proposal to fill an old limestone quarry with dry inert fill is within an area affected by the Environmental Protection Authority's System Six Recommendation MS. As the site is surrounded on three sides by Neerabup National Park, the potential impacts of the proposal on the values of the park need to be considered.

The potential for groundwater pollution is an issue of concern because the site is located about 800 metres upstream of an area designated by the Water Authority as a Priority 3 Public Water Supply Area.
