Problems/Comments
The Beaver Creek Radio Relay Station (BCRRS) was constructed in 1960 as part of the Ballistic Missile Early Warning System by the U.S. Air Force and operated until approximately 1975. Based on historical information, the BCRRS consisted of a one-story steel frame building without plumbing or windows, a tower, latrine, underground storage tank, parking lot, and waste disposal areas. The BCRRS has been used for power generation, waste disposal, transportation, and communication maintenance. Alascom has been leasing a 2.5 acre parcel of the property from the Air Force since 1984. An underground storage tank and associated petroleum contaminated soil was removed from the site in the early 1990s. A remedial investigation was conducted in 2014 at Site OT001, a 2.5-acre parcel of the Radio Relay Station that includes the radio relay building, tower, former underground storage tank, drainage ditch, historic biopile area, and potential waste disposal areas. Borings were advanced during the investigation, and soil samples were collected and analyzed for petroleum constituents, VOCs, SVOCs, PCBs, metals, and pesticides to determine whether any potential contaminant sources remained at Site OT001. Concentrations of these contaminants were not detected above the applicable cleanup levels for the site, and site closure was recommended for OT001. In addition to the Site OT001, formerly used areas along the ROW toward the BCCRS building maybe have been used for disposal. These areas were visually inspected during the 2014 RI. The areas were overgrown and did not appear to have been disturbed since they were originally cleared by the USACE in 1959 for pre-road construction test pitting. No evidence of debris burial was observed in these areas.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 7/14/1992 | Update or Other Action | (Old R:Base Action Code = FI - Field Inspection (General)). 11th CEOS conducted Field Inspection of the Beaver Creek RRS. | Former Staff |
| 7/20/1992 | Site Added to Database | Former Staff | |
| 12/9/1993 | Update or Other Action | File includes report by New Horizons - Apparently work had been planned for 1993 field season. | Bob Couch |
| 5/27/1994 | Update or Other Action | (Old R:Base Action Code = RPL2 - Site Information Request Letter). Staff sent PRP-CS Database Notification Letter to RP requesting update and more environmental information concerning contaminated site. | Jeff Peterson |
| 3/24/1997 | Update or Other Action | Site updated by Shannon and Wilson, based on the Air Force Relative Risk Evaluation Worksheet dated 9/12/95. The White Alice Site and Landfill were not assigned separate Reckey numbers due to the limited amount of investigation conducted to date. | S&W |
| 11/19/1999 | Update or Other Action | No actions have occurred at this site since Alascom cleanup. Air Force plans to do a comprehensive site inspection for asbestos, leaded paint, PCBs, and a document review in 2000. Decisions about future actions will be based on these reviews. | Tamar Stephens |
| 4/11/2002 | Update or Other Action | Review of draft Proposed Plan for Cleanup, Beaver Creek Radio Relay Site, Northway, Alaska, November 2001. Review letter sent and comments made. Action added by Sarah Riddle. | Tamar Stephens |
| 4/12/2002 | Update or Other Action | Review of Site Investigation, Beaver Creek RRS, Alaska (2000), and evaluation of the Beaver Creek Site for No Further Action. Action added by Sarah Riddle. | Tamar Stephens |
| 5/14/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed. | Tamar Stephens |
| 5/21/2014 | CERCLA RI Plan Approved | The ADEC Contaminated Site Program conditionally approved the Remedial Investigation Work Plan for the White Alice Communications Site OT001, Beaver Creek Radio Relay Station (BCRRS), Alaska. The ADEC stated that the description of Site OT001 should be revised to state that is only one 2.5-acre parcel of land within the larger BCRRS. The BCRRS appears to consist of a larger area that included waste disposal area along the road right of way, and another structure to the north of Site OT001. Further investigation of the other potential source areas may be necessary before ADEC will concur on site closure for the BCRRS White Alice Communications facility. | Jessica Morris |
| 5/20/2015 | CERCLA RI Report Approved | The ADEC Contaminated Site Program approved the Remedial Investigation Report for the White Alice Communications Site OT001, Beaver Creek Radio Relay Station (BCRRS), Alaska. Results of the RI revealed that concentrations of diesel range organics and residual range organics are present in surface and subsurface soil within a ditch at the site below the applicable site cleanup levels. Site closure was recommended for OT001. Formerly used areas along the ROW toward the BCCRS building could have been used for disposal. These areas were visually inspected during the 2014 RI and no evidence of debris burial was observed in these areas. | Jessica Morris |
| 9/17/2015 | Cleanup Complete Determination Issued | The ADEC Contaminated Sites Program approved the Site Closure Report for the Beaver Creek Radio Relay Station Site OT001. | Jessica Morris |
Contaminant Information
| Name | Level Description | Media | Comments |
|---|---|---|---|
| DRO | > Human Health/Ingestion/Inhalation | Soil | One surface soil sample contained a DRO concentration above the ingestion cleanup level; however sample locations 10 feet away from this result were nondetect for DRO. Groundwater is not present at the site due to topography and the presence of bedrock encountered during the site investigations. |
