Lake Way SOP Demonstration Plant

Closed 10 Apr 2019

Opened 3 Apr 2019


Salt Lake Potash proposes to develop the Lake Way SOP Demonstration Plant. The proposal is ocated in and around Lake Way, approximately 25 kilometres south of Wiluna.

The proposal will extract and evaporate natural brines to produce up to 50,000 tonnes per year of Sulphate of Potash (SOP).

The activities and infrastructure include:

  • On-playa infrastructure – brine extraction trenches; pond infrastructure; and associated pipework.
  • Off-playa infrastructure – processing plant, process water pipework and associated infrastructure

Why We Are Consulting

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.
