|Phosphate Mining in Southeastern Idaho|
The BLM Pocatello Field Office is situated at the heart of the Western Phosphate Field – the largest remaining phosphate deposit in the U.S. – and administers the Bureau's largest and most complex non-energy leasable minerals program. The BLM oversees 87 active phosphate leases in eastern Idaho on a total of 43,000 acres.
There are four active phosphate mines in the Pocatello Field Office: Rassmussen Ridge, South Rassmussen, Blackfoot Bridge and Smoky Canyon. The ore produced from these mines feeds industrial plants located in Pocatello and Soda Springs that produce phosphate fertilizer and elemental phosphorus.
The Pocatello Field Office is also analyzing the potential environmental impacts of several proposals for new mines or expansions of existing operations. The name of each project is linked to the project page in the NEPA Register.
