Problems/Comments
The site was in operation from 1956 to 1971. The Inside transformer located in the southwest section of the module train leaked onto the soils beneath the building. Contaminants include PCBs associated with the transformer. IRP site OT004. See also Reckey 198931X902505. Exposure pathways identified as inhalation and ingestion of PCB-contaminated soil/dust for humans and other mammals; skin contact during "dusting" and picking up grit for their crops and some ingestion during preening. Receptors include Inupiat subsistence hunters and mammals (including the endangered polar bear). The site was assigned a MEDIUM overall risk on the Air Force Relative Risk Evaluation Worksheet dated 10/25/95. Site entered by Shannon and Wilson.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 1/23/1997 | Site Added to Database | PCBs. Site added by Shannon and Wilson. See also original site 198931X902505. | S&W |
| 1/21/2003 | Update or Other Action | Site is scheduled for cleanup in 2005. | Ann Farris |
| 5/20/2003 | Site Number Identifier Changed | Changed the Region from 36 to 31. | Former Staff |
| 12/18/2003 | Update or Other Action | Staff reviewed sampling results from Bullen Point and Point Lonely Distant Early Warning (DEW) Line sites. Air Force, United States Army Corps of Engineers, and ADEC personnel conducted a site visit of these two installations in August 2003 and collected a limited number of soil and water samples. At Bullen, sample collection was focused around the former radome and a small tundra pond west of the former fuel storage area that had a noticeable sheen. The samples by the Radome had PCB concentrations up to 3.7 mg/kg in soil. This area will be remediated as part of clean sweep. | Ann Farris |
| 8/13/2004 | Site Characterization Workplan Approved | The ADEC reviewed and commented on a Draft Remedial Investigation/ Feasibility Quality Program Plan for 8 sites. Comment resolution with the Air Force has been completed and the final version of the plan is expected in August. Soil samples will be collected at the Inside Transformer site to further delineate the PCB contamination. | Ann Farris |

| 10/1/2007 | Record of Decision | Based on the results of the FS, the USAF selects the following remedy: • excavation of soil with PCBs above 1 mg/Kg at the west end of the old radome building (an estimated volume of 69 cubic yards [yd3]); • transportation of PCB contaminated soil to an offsite treatment, storage and disposal facility (TSD) for disposal; and • disposal of soils will be consistent with the Off-Site Rule (40 CFR 300.440). | Debra Caillouet |
| 7/31/2008 | Update or Other Action | The Clean Sweep Remedial Action Report was approved. A total of 19.4 cy of PCB contaminated soil was containerized and shipped offsite for disposal. MI Confirmation sample results were 0.430, 0.210 and 0.202 mg/kg | Debra Caillouet |
| 8/29/2008 | Site Closure Approved | The Clean Sweep Remedial Action Report Final July 2008 documents the removal of all PCB soil to below 1 mg/kg. The site is closed | Debra Caillouet |
