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
Unreported leaks or spills from above-ground storage tanks appear to be the source of petroleum contaminated soil. The area of concern includes FAA Summit former housing buildings 100, 103, 106, 107, and 600. Contaminants include gasoline and diesel range organics (GRO, DRO) and polycyclic aromatic hydrocarbons (PAHs). No groundwater samples exceeded DEC Table C cleanup levels. No remediation has taken place at this area of concern. Former housing buildings 101, 102, 104, and 105 did not have evidence of soil contamination above DEC cleanup levels and were non-qualifying.
Action Information
Action Date | Action | Description | DEC Staff |
---|---|---|---|
5/4/2016 | Site Characterization Report Approved | DEC approved Follow-on Site Investigation Report for FAA Summit Station. There were two primary objectives for the follow-on site investigation activities: 1) to further delineate the extent of petroleum contamination at the Summit FAA Station and 2) to determine the nature of the subsurface water at the site. The report concluded that the subsurface water monitored at the Summit FAA Station is not expected to transport any contaminants to nearby surface water or drinking water sources which have been located a minimum of approximately 5 miles away. | Joy Whitsel |
10/6/2016 | Site Added to Database | A new site has been added to the database | Mitzi Read |
2/6/2017 | Meeting or Teleconference Held | DEC met with FAA and contractors to discuss steps necessary for closure. For Former Housing North (HazardID 26620) HRC results will be accepted. For areas of concern (AOCs) where contamination of groundwater or infiltrating subsurface water is present, DEC agrees to review groundwater modeling that proposes to demonstrate that the contamination plume is at equilibrium. Calculation of cumulative risk will be based on source area and assessed on a site by site basis. Regarding establishment of institutional controls (ICSs) at the site, DEC is concerned that the landowner Alaska Dept of Transportation (ADOT) lacks an existing mechanism for tracking and maintaining ICs. Future coordination between the FAA, ADEC and the ADOT will be necessary have to successfully implement ICs restricting groundwater usage. | Joy Whitsel |
