Site Characterization Report Approved |
Reviewed and approved RA report. During remedial actions in 2021 the former landfill face, former burn area, and other areas of concern were excavated. A total of 1,349 cubic yards (cy) of non-hazardous and 69 cy of hazardous soil were barged out of state for disposal at Columbia Ridge Landfill in Arlington, Oregon.
Samples collected following excavation indicated that that DRO and dioxins exceed the applicable cleanup levels at the edges of the former landfill burn area, landfill face, and landfill surface areas on the south side of the landfill. The FAA recommends an iterative approach of excavation and sampling to remove the remaining contamination in these areas. DEC agrees with the recommendations and the report is approved.
