Problems/Comments
On April 21, 2004 Arctec Alaska reported a spill of approximately 150 gallons of diesel fuel at the Indian Mountain Long Range Radar Site that they operate for the U.S. Air Force. After responders excavated soils surrounding the industrial building there was a small amount of contamination left over. The contamination has penetrated to a subsurface liner where it then spread laterally through a thin sand layer without penetrating the liner. Further excavation was considered impracticable because of the risk of penetrating the liner. Arctec Alaska estimates that approximately one cubic yard of highly contaminated soil remains in place. A "worst case" sample taken of the sand layer directly above the liner shows the maximum degree of contamination had a DRO concentration of 5,190 mg/kg. This site was transferred from PERP.

| 3/6/2018 | Meeting or Teleconference Held | DEC met with US Air Force (USAF) staff to review and discuss cleanup progress at all the Indian Mountain sites. The only ongoing work is the long-term monitoring (LTM) work at eight sites (SD001, LF004, LF005, LF006, SS011, SS002, SS009, SS010). Tentatively, there is additional work at OT008, Upper Camp PCB Spill and MMRP sites planned for 2019, pending funding from the USAF. The other sites; LUST, 2004 Spill Arctec, Fuel Offload Area (PL510) and the Incinerator Fuel Line were reviewed and discussed for a cleanup path forward. | Erica Blake |
| 8/31/2018 | Site Visit | DEC conducted a brief 4-hour site visit at the Indian Mountain Long Range Radar Station sites. DEC observed sites at both the Upper and Lower Camp areas. A lot of the Lower Camp sites extend into thick brush and wooded areas, and because time on the ground was limited, not all of those areas were inspected closely. At the Upper Camp, some of the sites are on the sides of very steep slopes, and were not visited. Warning signs were recently installed, and were visible at all the areas of concern. | Erica Blake |
