Eramurra Solar Salt Project - Environment Review Document

Leichhardt Salt Pty Ltd is proposing to develop a solar salt project in the Cape Preston East area, approximately 55 km southwest of Karratha in WA. The Proposal will utilise seawater and evaporation to produce a concentrated salt product for export.

Leichhardt Salt Pty Ltd has prepared the Environmental Review Document in accordance with Environmental Protection Authority (EPA) procedures and is released for public review. The Environmental Review Document describes the Proposal, the likely environmental impacts and the proposed management measures.

The Environment Review Document and supporting appendices can be found for review below.
