We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. 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
Warehouse was used as temporary storage of all deliverables, possibly including transformers. Contaminants of concern are PCBs (1-10 mg/kg) and DRO (2660 mg/kg). Located in lower camp. The site ranked with a current exposure for direct contact with surface soil contaminated with PCBs between 1 and 10 mg/kg. Current site use is anticipated to be extremely limited due to the remote nature of the site. Soil sampling during the 2009 Clean Sweep descovered PCB-soil contamination up to 9.3 mg/kg adjacent to the western door. 4 cubic feet of soil was removed and soil testing confirmed concentrations were non-detect, indicating cleanup levels were met. 1,2,3-Trichloropropane contamination up to 1.5 mg/kg was descovered south of the southeast corner of the warehouse concrete pad. 2 cubic feet of soil was removed and soil testing confirmed concentrations were below clean up levels.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 7/28/2008 | Site Added to Database | Site added to the database. | Mitzi Read |
| 7/29/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed. The site ranked with a current exposure for direct contact with surface soil contaminated with PCBs between 1 and 10 mg/kg. Current site use is anticipated to be extremely limited due to the remote nature of the site. | Kim DeRuyter |
| 4/28/2010 | Update or Other Action | Updated ETM ranking based on Clean Sweep 2009 cleanup activities. Excavation and removal of contaminated soil and subsequent testing found PCBs below the cleanup level. Site ranked as De Minimis exposure for direct contact with surface soil, subsurface soil, and outdoor air inhalation. | James Ward |
| 5/24/2010 | CERCLA ROD Approved | THe Record of Decision was signed by the Department and the Air Force. | Kim DeRuyter |
| 7/24/2010 | Cleanup Complete Determination Issued | Final confirmation samples indicate that contaminant concentrations are all below cleanup levels and this site will be closed with out the need for institutional controls. | Kim DeRuyter |
| 9/14/2010 | Institutional Control Record Removed | Institutional Controls have been removed. | Kim DeRuyter |
| 12/19/2023 | Update or Other Action | ACKNOWLEDGEMENT OF RECEIPT: Preliminary Assessment (PA) Report for Aqueous Film-Forming Foam (AFFF) Areas, Kalakaket Creek Radio Relay Station, Alaska. In October 2023, USAF submitted a PA Report for AFFF at the former Kalakaket RRS. While USAF does not have good documentation or information about the activities that occurred when the Kalakaket installation was active, the PA presents several lines of evidence that AFFF was stored at Kalakaket. The conclusion reached in this PA is that no further action is warranted due to a lack of documentation that AFFF was released. However, based on the cited 1991 EPA PA guidance, before 'no further action' can be recommended, USAF must be certain that CERCLA hazardous substances have never been at the site. A lack of information cannot be interpreted to indicate that no hazardous waste is present or has ever been deposited at the site. DEC acknowledges receipt of the Kalakaket AFFF PA but specifically does not approve it. In the future, additional PFAS sampling may be required in areas described in this PA. | Jamie McKellar |
