The United States Air Force invites the public to review and comment on the Proposed Plan for the preferred alternative and rationale for cleaning up manganese and polychlorinated biphenyl (PCB) -contaminated sediment and subsurface soil at Installation Restoration Program Site UK510 at Scott Air Force Base, Ill.


A Remedial Investigation/Feasibility Study was finalized in June 2022 for UK510. The Remedial Investigation portion of the study provided a summary of the site history, which included results from the Remedial Investigation completed in 2017 through 2021. The Feasibility Study portion evaluated three remedial alternatives. Those alternatives were no action, land use controls, and removal and off-site disposal with land use controls.


The UK510 proposed plan recommended removal and off-site disposal of contaminated sediment and subsurface soils followed by implementation of land use controls. The recommendation was selected over the other alternatives in order to achieve short and long-term risk reduction by removing sediment and subsurface soil containing contaminants that exceed the remediation goals. The recommended alternative is technically and administratively feasible, protective of human health and the environment, and cost-effective. The USAF has selected the preferred alternative for UK510 and the Illinois Environmental Protection Agency concurs with USAF’s selection.
