Advisory council greenlights data compilation to quantify salts removed by mineral-extraction operations
Summary
Council members discussed a proposed $27,000 scoped study to compile public and confidential mineral-extraction data (pumping volumes, diversion points, return flows) from companies including Mort's Salt, US Magnesium, Cargill and Compass to better quantify salts removed from the lake.
The advisory council reviewed a short work plan to compile and evaluate mineral-extraction data aimed at quantifying water and salt removed from Great Salt Lake by commercial operations.
Speaker 5 outlined a scoped, short-term data-compilation effort tailored to the council’s earlier concept, noting the work would focus on publicly available records and on obtaining non-public company data in aggregated form to avoid revealing confidential business details. The proposed initial budget for the work was described as about $27,000 and the stated deliverables are: a data inventory, aggregated estimates of pumping volumes and return flows, and a recommended scope for follow-on work.
The presenter reported preliminary conversations with four companies: Mort's Salt, US Magnesium, Cargill and Compass, and said those companies expressed willingness to assist by sharing data where feasible. The council discussed confidentiality constraints and how aggregated reporting could preserve companies’ proprietary details while informing the salt-balance analysis.
Committee members welcomed the study as a way to fill persistent knowledge gaps. Bill Johnson cautioned that legislation concerning extraction activity had advanced before some study work was complete and urged that the advisory council remain a central forum for technical discussion.
Next steps: staff will refine contracting pathways and confirm funding sources (advisory council funds that may lapse were referenced), and coordinate engagement protocols with participating companies. The compiled data will inform the broader salinity-management and CMP workstreams.
