The Eastern Michaud Flats Superfund Site covers approximately 2,530 acres northwest of Pocatello, Idaho. It includes two adjacent phosphate ore processing facilities. The former FMC Corporation operated a facility from the early 1940’s until December 2001. The J.R. Simplot Company Don Plant is still an active facility. EPA issued a Record of Decision (ROD) for the site in 1998. A Supplemental Remedial Investigation and Feasibility Study (RI/FS) was issued in 2010 for the FMC portion of the site, while groundwater remediation at the Simplot site is ongoing.
Site Update
EPA’s cleanup plan - called an Interim Record of Decision Amendment- for the former FMC plant at the Eastern Michaud Flats Superfund site focuses on elemental phosphorus, metals, and radiation in soils, fill, and groundwater. The plan will protect people, animals, and the environment from contamination.
