The Alaska Department of Environmental Conservation (ADEC) has reviewed the aforementioned report for remedial action and remedial investigation which occurred at the non-landfill areas of concern (AOCs) at the Federal Aviation Administration (FAA) Level Island contaminated site located on Level Island located near Wrangell, AK.
ADEC will evaluate the Beach Barge Connection (PX AOC 1) and Building 105 UST 44-A-3 (RTH AOC 1) for closure.
The remaining AOCs including the South Drum Storage Rack (SAL AOC 4), the Pipeline, Tank Farm and Pumphouse (PX AOC 1), and the Building 622 UST 44-A-4 (SAL AOC 5) require additional characterization or monitoring.
ADEC comments from the letter dated May 9, 2022 were addressed in the final version of the document, the non-landfill Release Investigation and Remedial Action Report is approved as written. The FAA Level Island landfill project is ongoing and will be detailed in a separate report.

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.
