It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Site assessment for road re-route revealed underground contamination associated with a bulk fuel tank farm that consisted of eleven, 5,000-gallon, underground storage tanks (USTs) storing both diesel and gasoline. USTs were removed from the shoreline where an underground fuel tank farm was located. Fuel lines are present from the shoreline into Millerville, a housing complex formerly operated by the military. Heating oil was distributed to housing via pipeline from the UST farm formerly located between Tongass Avenue and the harbor shoreline.

3/1/2010 Report or Workplan Review - Other Evaluation of DERP FUDs Area K data located within the ADOT&PF Sitka Airport Access Road site for a proposed CORPs IC agreement for residual soil & sediment contamination. Estimated volume of 14,100 cubic yards of residual petroleum contamination will be left in-place in subsurface soil and sediment under a Notice of Environmental Contamination Institutional Control statement submitted for ADOT&PF approval by USACE FUDs. Rational is that petroleum contamination extended below the water table and extent is unkown; floating product was observed. Large rocks were placed in the exposed groundwater and contaminated material was backfilled on top of the rock layer. Sediments and surface water are contaminated with petroleum product (DRO and SVOCs) and water samples contained concentrations of lead above the CWA AWQC. (1996 Phase II Report Sitka NOB Woodward Clyde). Located under the airport employee parking area, a pipeline may have extended along Airport Road to Tongass Drive through Millerville Housing to the former Navy Dock in the east side of the island. More likely UST Tank Farm No. 3 supplied diesel fuel to the airport. Bruce Wanstall
