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
Spill occurred in 1980 when one of the diesel fuel storage tanks east of the power plant (Lower Camp area) was overfilled and spilled an estimated 3,000 gallons of diesel fuel onto the ground. No fuel was recovered, and the site has never been sampled. Air Force name for this site is Spill/Leak No. 1 (ST004). This site also includes spill no. 1639992402; PPRP file no. 465.02.001. On 8/29/16 ~500 gallons of #1 (arctic grade) diesel were released to the ground during construction activities to build a seawall when a mobile tank was overfilled. Initial response actions included recovery of ~100 gallons of fuel, excavation of ~40 cubic yards of surface soil (top three inches); and covering the impacted area with gravel. In 2017 an additional 394 cubic yards of contaminated soil were removed and shipped off-site. Water with a sheen and discolored soil were encountered during this excavation, possibly due to contamination migrating from the upgradient release of 3,000 gallons of diesel fuel that occurred at ST004 in 1980. Additional investigation is needed.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 6/7/2004 | Site Added to Database | DRO. | Tamar Stephens |
| 7/8/2004 | Site Characterization Report Approved | Reviewed and sent approval letter. Investigation was conducted summer 2003. Analysis of soil samples for petroleum hydrocarbons detected a maximum concentration of 2819 mg/kg diesel range organics, which is below the Method 2 arctic zone cleanup level of 12,500 mg/kg, and a maximum of 140 mg/kg of gasoline range organics, which is below the Method 2 arctic zone cleanup level of 1400 mg/kg. No other compounds were detected above regulatory screening levels. Recommended that the Air Force prepare a "No Further Action" decision document. | Tamar Stephens |
| 2/4/2005 | GIS Position Updated | Updated position using coarse census bureau "places of interest" dataset. Moved from Point Hope to general Cape Lisburne location. | Torsten Ernst |
| 12/22/2005 | Update or Other Action | The Air Force project manager informed DEC staff Tamar Stephens by telephone that the Air Force has contracted to have a decision document prepared for this site; it is expected to be completed in spring of 2006. | Tamar Stephens |
| 6/28/2007 | Record of Decision | John Halverson signed Decision Documents for ST004 for conditional closure with land use controls. Signed by Colonel Joseph M. Skaja for Air Force on June 14, 2007. Conditional closure will be recorded once DEC receives documentation that LUCs are in place. DRO max = 2810 mg/kg. Land Use Controls (LUCs) will be in place until reaches 230 mg/kg. LUCs consist of: 1) Site boundaries will be surveyed to provide a description of the location where soil has a concentration of DRO above 230 mg/kg; 2) The Base Master Plan for Cape Lisburne LRRS will include a statement that ADEC approval is required prior to off-site transportation or disposal of site ST004 soil containing DRO above 230 mg/kg; 3) If the site is transferred, the statement that ADEC approval is required prior to off-site transportation or disposal of site ST004 soil containing DRO above 230 mg/kg will be included in the property transfer documents. | Tamar Stephens |
| 3/13/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed. | Tamar Stephens |
| 5/17/2012 | Update or Other Action | DEC received site boundary survey documentation, one of the components of the Decision Document. | Tamar Stephens |
| 6/20/2012 | Update or Other Action | DEC received documentation that information is entered on the Base Master Plan as required in the Decision Document. | Tamar Stephens |
| 6/20/2012 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 72928 Cape Lisburne LRRS Spill/Leak No. 1. | Tamar Stephens |
| 6/21/2012 | Cleanup Complete Determination Issued | A "cleanup complete" letter was sent to the Air Force. DEC agrees that the components of the Decision Document have been met. The only compound of concern identified at this site is diesel range organics, and the maximum concentration detected was 2,810 mg/kg, which is below the 18 AAC 75.341 Table B2 arctic zone cleanup level of 12,500 mg/kg. | Tamar Stephens |
| 5/31/2018 | Spill Transferred from Prevention Preparedness and Response Program | Spill transferred by PPRP staff John Ebel. Spill no. 1639992402; spill date = 8/29/16; substance = #1 (arctic grade) diesel; quantity = ~500 gallons; source = mobile tank; PPRP file no. 465.02.001; description: during construction activities to build a seawall, a mobile tank was overfilled.
