Mackay Sulphate of Potash Project

Closed 21 Jan 2019

Opened 15 Jan 2019

Overview

The Proposal involves the development of a greenfields Sulphate of Potash fertiliser operation which is currently designed to operate for a 20-year period.

The Proposal involves the on-lake development of trenches and solar evaporation ponds for brine extraction and Sulphate of Potash production. The off-lake development includes a processing plant, associated site infrastructure and access roads for trucking Sulphate of Potash product to Wyndham Port.

A northern linear access corridor will include the primary site access road, and potentially a water supply pipeline. A southern infrastructure corridor may be used as an alternate water supply option.

The Proposal is located within Western Australia at Lake Mackay on the border with the Northern Territory, 600 km west of Alice Springs and approximately 1000 km south of Halls Creek by road.

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.
