SaLUT performed the first phase of the remedial action at the St. Louis Airport Site under the Department of Energy Formerly Utilized Sites Remedial Action Program (FUSRAP). In the 1940s, the site had been used by the Manhattan Engineer District to store residue from uranium ore processing in the St. Louis area. This project was performed as a turnkey operation. SaLUT's responsibilities included detailed design to meet the performance specifications, health and safety planning, excavation, transportation and disposal of contaminated material, liner construction and quality control, and site restoration. SaLUT designed sediment and erosion controls and developed an emergency plan to prevent off-site contamination during construction.
