Salt Lake Potash Limited propose to abstract Sulphate of Potash (SOP) rich brines to produce up to 260 kilotonnes per annum (ktpa) of SOP product. The proposal is located in and around Lake Way, approximately 25 kilometres south of Wiluna.

The activities and infrastructure proposed includes evaporation ponds, brine abstraction trenches, paleochannel brine production bores, permanent brine pumps/pipework, access and infrastructure corridors and excess salt disposal areas.

The proposal will cover a disturbance area of 2,750 hectares within a 25,010 hectares Development Envelope and is for a project lifespan of 20 years.

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.
