SEATTLE — The FMC Corporation will begin cleanup work at the former FMC facility near Pocatello under a Unilateral Administrative Order (UAO) from the Environmental Protection Agency (EPA), according to a press release.

The Order outlines a schedule and other terms which will guide the implementation of the cleanup work outlined in the Interim Record of Decision issued last year.

The FMC facility lies within Eastern Michaud Flats Superfund Site and occupies more than one thousand acres of the Shoshone-Bannock Tribes’ Fort Hall Reservation, stated the release.

The primary contaminants of concern at the site are arsenic, elemental phosphorous and gamma radiation.

The actions FMC will execute under the Order are expected to cost close to $57 million and be completed in 3 to 5 years, noted the release.

“This Order paves the way for FMC to address the contamination at the former FMC facility,” said Rick Albright, director of EPA’s Superfund office in Seattle. “FMC will immediately begin the engineering design work and we hope to see heavy equipment on site and working by next summer.”

EPA’s UAO requires FMC to design, implement and pay for the actions specified in the September 2012 Interim Record of Decision Amendment (IRODA) ( under oversight by EPA, the state of Idaho and the Shoshone-Bannock Tribes. Specific requirements include:

• Development of detailed technical plans and specifications for the cleanup actions.

• Construction of engineered covers over contaminated soil.

• Treatment of groundwater to prevent contaminants from migrating toward the Portneuf River.
