Problems/Comments
From 1953 until 1962, the former Nuvagapak Point DEW Line Station was used as a radar defense facility. Original site improvements consisted of a composite building, shop building, warehouse, a 240-foot-tall radio tower, various storage sheds, a fuel pipeline, and a fuel-storage system consisting of a pump house and aboveground storage tanks (ASTs) (Figure 2). These structures were subsequently removed in 1994 and 2000 during several phases of site investigation and execution of remedial activities. The Nuvagapak Point DEW Line Station was an installation of the DOD under the jurisdiction of the Department of the Air Force until August 10, 1965, when jurisdiction was passed to the Department of the Navy. The Navy filed a Notice of Intent to Relinquish on February 11, 1970. The site acreage was selected for inclusion into ANWR on December 2, 1980; transfer to the Bureau of Land Management and U.S. Fish and Wildlife Service (USFWS) became effective on March 28, 1985. Management control was given to the USFWS on March 28, 1985. The Shop Area was a 30-ft by 40-ft structure in the southeastern portion of the main gravel pad. It was described as being “built upon a heavily reinforced concrete pad which sat on top of a heavily reinforced wood floor and wood piling foundation.” This structure, including the foundation, was demolished during the 1994 removal action. The USACE excavated approximately 50 tons of petroleum-contaminated soil from underneath the Shop Area after its removal. Soil remained in this area that exceeds the PCB cleanup level of 1.0 mg/kg.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 1/26/2016 | Site Added to Database | A new site has been added to the database. This site was previously identified in the Decision Document but was not included as a separate site. Subsequent work at the Shop Area identified polychlorinated biphenyls as the chemical of concern. the 2015 field work also identified petroleum hydrocarbons, and future work will be required. | Mitzi Read |
| 1/28/2016 | Document, Report, or Work plan Review - other | Provided comments on DRAFT remedial action at multiple sites, including Drum Dump D, AST Pad, Composite Building, Debris Pile A, and Shop Area. Request for increase of cleanup level in Drum Dump D area proposed based on background study. Further cleanup at Shop Area required, and contaminated waste material continues to be staged at site due to difficulties in site access by barges for consecutive field seasons. | John Carnahan |
