Welcome to FMC Pocatello, Idaho

From 1949 until 2001, FMC Corporation operated the world’s largest elemental phosphorus plant in Power County, Idaho, just outside Pocatello, employing upwards of 650 individuals at full production.

Since the plant’s closure, FMC has worked with the U.S. Environmental Protection Agency (EPA), the State of Idaho, and the Shoshone-Bannock Tribes to develop a cleanup plan for the property that is environmentally protective and ensures the health and safety of both workers and the general public.

The Eastern Michaud Flats Superfund Site, which includes both the FMC plant site and the J.R. Simplot Co. plant site, was listed on the Superfund National Priorities List in 1990. FMC’s priority has always been to make good on our commitment to clean up the property, to do it in a safe and responsible way, and to get it redeveloped for the benefit of the community.

On September 27, 2012, EPA published an Interim Amendment to the Record of Decision (IRODA) that selected a cleanup plan for the FMC site. The selected cleanup includes capping of contaminated soil and extraction and treatment of contaminated groundwater. The IRODA has the support of the State of Idaho; the Shoshone-Bannock Tribes did not concur with EPA’s remedy.

On June 10, 2013, EPA issued a Unilateral Administrative Order for Remedial Design and Remedial Action (UAO) to FMC under which the company is implementing the IRODA remedy. The UAO spells out the specific steps FMC must follow to develop the remedial engineering design and perform the site cleanup.

EPA has reviewed and approved the soil remedy design and work plan FMC completed those steps during the summer of 2013 and obtained EPA approval of the remedial design work plan allowing site-wide grading in 2014. Capping began in late 2015 under EPA-approved work plans and was completed in 2017. The groundwater remedial design is undergoing EPA review and approval, and includes work plans to collect some additional field data to support development of the groundwater extraction and treatment system. Construction of the groundwater remedy is anticipated to commence in 2019.

Overview of Soil Remedy Construction

On September 22, 2014, FMC and its soil remedy construction contractor began the Site-Wide Grading Phase of the interim remedy selected in the IRODA. Site-wide grading prepared the site for cap placement and managing on-site stormwater. The site-wide grading work was completed by the end of the 2015 construction season. FMC also started placing caps on the site in late 2015 and completed cap placement in 2017

There are two types of caps that are being constructed: (1) gamma caps, which consist of a 14 inch soil cover over areas of the site where naturally occurring radiation from shale/slag are present, and (2) evapotranspirative caps (ET caps) which consist of 30 inches of soil over a capillary barrier where infiltration of rain and snow-melt needs to be minimized to prevent groundwater contamination. Both caps have been seeded with native plants. The caps will be maintained in the future under an EPA-approved Operations, Monitoring & Maintenance Plan. Soil for the capping work was obtained from the existing borrow pit in the Western Undeveloped Area of the property, an area covering approximately 80 acres. This is land owned by FMC and had no role in phosphorus production activities. Reclamation of the borrow pit was completed in 2017.Prior to the commencement of capping and in coordination with the Shoshone-Bannock Tribes Cultural Resources Office and the State Historic Preservation Office, EPA conducted a cultural resource survey in the Western Undeveloped Area to ensure that no historic artifacts would be impacted by the soil excavation.

Because most of the remediation of the FMC site is taking place within the boundaries of an Indian reservation, FMC required its construction contractor to hire local personnel using Native American hiring preferences authorized under the Federal Civil Rights Act. In 2015, approximately one-half of the 30 local positions available were filled by Native Americans. Hiring by Envirocon during the 2016 and 2017 construction season also provided preference for Native Americans.

Construction of the groundwater extraction and treatment system is expected to commence in 2019. The system will utilize a network of extraction wells to extract contaminated groundwater and prevent its migration to areas down-gradient from the plant site. Extracted groundwater will be treated to drinking water standards and/or risk-based cleanup levels, unless it can be sent to the City of Pocatello’s wastewater treatment plant (POTW), in which case it will be pre-treated to POTW requirements. Treated groundwater will either be discharged to infiltration ponds for evaporation or percolation, or be re-injected directly, or discharged to the Pocatello POTW. Ongoing field studies will help with determining the best approach. EPA is currently reviewing FMC’s proposed groundwater extraction and treatment system design plans. FMC will continue to work with EPA to refine and further develop those design plans.

FMC is responsible for all cleanup costs. FMC originally anticipated that the cleanup would have a final cost of approximately $60 million and take three to four years to complete. To date, FMC has spent $58 million to implement the soil remedy. This cost does not include the groundwater component of the remedy, which the IRODA estimated to cost approximately $10 million but for which FMC does not yet have an estimated cost.

FMC is pleased to be moving forward under the UAO to implement the IRODA. The UAO allows for expedited implementation, eliminates time-consuming administrative steps, and allows cleanup to move forward without further delay. The IRODA and UAO represent the culmination of almost twenty-five years of investigation and exhaustive study and evaluation of all known potential remedial technologies. The remedial actions specified in those documents are 1) scientifically sound, 2) protective of human health and the environment, and 3) consistent with remedial actions implemented successfully at similar elemental phosphorus sites around the country.

Current and Future Redevelopment Projects

While implementing the UAO and IRODA, FMC is continuing to work with the Power County Development Authority (PCDA) to market the property for redevelopment. Until the IRODA was issued, uncertainties regarding the scope and timing of the cleanup action deterred interested developers. Now that the IRODA and UAO have been issued and FMC is carrying out the site cleanup actions that EPA selected, these barriers to redevelopment have been removed and strong interest is being expressed by developers.

ValleyAgronomics, LLC is the first of hopefully many projects that will locate on the property. On a 20 acre area in the northeast corner of the FMC site, Valley Agronomics constructed a fertilizer distribution facility which services the agricultural community of Eastern Idaho and Northern Utah, creating approximately 50 good paying jobs. It is the largest fertilizer blending and distribution facility in Idaho, representing an approximate $12 million investment. In its first year of business in 2017, Valley Agronomics distributed over 65,000 tons of fertilizer to farms in Eastern Idaho and Northern Utah.

Valley Agronomics is also planning to construct an office, retail and warehousing complex, and propane distribution facility in a different area of the FMC site. In the meantime, the Power County Development Authority has signed a listing agreement with CBRE for northern properties totaling approximately 73 acres located north of I-86.

The FMC site is uniquely situated to support good paying, industrial jobs and to immediately start contributing again to the local economies. The property is zoned for heavy industrial use and offers excellent infrastructure including rail, electrical transmission, access to interstate highways, and proximity to the Pocatello Regional Airport. We have seen how redevelopment can occur as the clean up progresses, and we are proud of the collaborative work between FMC and EPA to make this happen for the good of all Southeast Idaho.
