VRX Silica Ltd propose to develop a silica sand mine in the Geraldton Sandplain bioregion of Western Australia, approximately 270 km north of Perth. The proposal would include a total disturbance of 412.2 hectares of native vegetation and will involve sequential mining of sand 8 – 15 metres below the soil surface.

Alternatives to Environmental Impact Assessment process. An EIA process is conducted for a project and its alternatives (e.g. different locations, scales, designs). Alternatives are the "raw material" of EIA process. The different alternatives can be clearly assessed to help the decision makers to select the best available option.

Sand, perlite, grog, and vermiculite contain free silica and are, therefore, highly toxic by inhalation. Vermiculite is also frequently contaminated with asbestos. There is a danger of accidents if clay or water can be added while the mixer is in operation. Bags of clay and glaze materials can be very heavy, and lifting can cause back problems.

The EPA now has 28 days to determine whether to assess the referred proposal and, if so, what level of assessment to assign. "This referral to the EPA commences the process for environmental approval for VRX Silica's Arrowsmith Central Silica Sand Project, which is our second silica sand project at Arrowsmith.

Silica exposure is a well-known danger for workers in mining and construction. With the spread of frac sand mining, however, silica air pollution has also become a danger for residents near sand mining and processing operations. Children, older adults and people with respiratory diseases are especially at risk.
