Problems/Comments
Occurred in 1982 when 1,500 gallons of aviation gas was spilled on the runway apron in the Lower Camp area. No fuel was recovered from the spill. Small area of stained sediment was found by a survey team in a nearby drainage ditch in 1987, but no samples have ever been collected. The runway has been graded many times since the spill occurred. Air Force name for this site is Spill/Leak No. 2 (ST005).
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 6/7/2004 | Site Added to Database | Aviation gas. | Tamar Stephens |
| 7/8/2004 | Site Characterization Report Approved | Stephens sent approval letter. Analysis of soil samples for petroleum hydrocarbons detected a maximum concentration of diesel range organics of 503 mg/kg, which is below the Method 2 arctic zone cleanup level of 12,500 mg/kg. No other compounds were detected above regulatory screening levels. Letter recommended that Air Force proceed with preparing 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 | 5John 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 = 503 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. | 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 72929 Cape Lisburne LRRS Spill/Leak No. 2. | 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. Compounds of concern identified at this site are diesel range organics (DRO) and benzene. The maximum concentration of DRO detected in soil is 503 mg/kg, which is below the 18 AAC 75.341 Table B2 arctic zone cleanup level of 12,500 mg/kg. The maximum concentration of benzene detected in soil is 0.035 mg/kg, which is below the Table B1 arctic zone cleanup level of 13 mg/kg. | Tamar Stephens |
