Mardie Salt Project

Overview

Mardie Minerals Pty Ltd proposes to develop a high volume salt and Sulphate of Potash project at Mardie, approximately 80 km south west of Karratha, in the Pilbara Region of Western Australia.  The proposal would utilise seawater and evaporation to produce a concentrated salt product and other associated products.

The proposal includes a seawater intake, evaporation ponds, processing plant, bitterns disposal pipeline and outfall, desalination plant, freshwater supply bores and associated infrastructure. The only waste product would be approximately 3.6 GLp/a of bitterns.

The proposal would include disturbance of up to 9,365 hectares on shore, and up to 40 hectares of marine environment.

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
