- Facility Demolition & Remediation
The 6-acre former Agrium Advanced Technologies Facility produced dry micronutrient fertilizer products until production was ceased in 2014 when current owner Loveland Products/Crop Production Services (CPS) acquired the property. The facility has been under Resource Conservation and Recovery Act (RCRA) Corrective Action (RCA) since the 1980s due to metals contamination, and Solid Waste Management Units (SWMUs) outside of the buildings were remediated in the 1990s and 2000s. Forward progress stalled as SWMUs within the buildings had not been investigated or remediated. In the spring of 2016, the client’s goals for the site changed to include redevelopment of the property; minimization of risk; and minimization of long-term environmental management needs. Our team developed an adaptive approach to integrate soil remediation under the RCA process simultaneous with facility demolition. The client established an aggressive 8-month goal to complete all demolition and remediation by the end of 2016.
Meeting with the regulatory agencies to conceptualize the integration of remediation and demolition within the RCA framework was crucial to project success. We prepared a remediation work plan that included decision trees and detailed directions on potential field iterations. Open communication was promoted between team members and the regulators, which allowed the project team to address concerns as they arose. The project involved the on-site treatment of soils containing metals and nutrients, which allowed for the disposal of the soil as nonhazardous resulting in significant savings for the client. Site restoration included grading and surfacing to ready the site for future industrial development. All field work was completed with zero safety recordables for approximately 4,000 work hours. The project received a 2018 Merit Award from the Nebraska American Council of Engineering Companies.
