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
The station dates of operation are 1953 to the present. Site consists of 6 200,000 gallon above ground tanks and associated piping. Contaminants associated with the Petroleum, Oil, Lubricants (POL) tanks include arctic grade diesel and lead. Sampling in 2003 indicated some low level diesel contamination, but no further migration appears to be occurring. Additional sampling is necessary when the tanks are removed. IRP site SS017. See also Reckey 198931X902508. Exposure pathways identified as ingestion/inhalation of dust/soil for humans, other mammals, and birds. Potential receptors identified as installation workers and visitors, and birds and mammals utilizing the lagoon adjacent to the site, or "dusting themselves on the gravel pads. The site was assigned a HIGH overall risk on the Air Force Relative Risk Evaluation Worksheet dated 10/25/95. Site entered by Shannon and Wilson.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 10/25/1995 | Update or Other Action | (Old R:Base Action Code = RI - Remedial Investigation). Action date used is the date of the Air Force Relative Risk Evaluation Worksheet, which indicates the site is in the RI phase. | Former Staff |
| 3/3/1997 | Site Added to Database | Site added by Shannon and Wilson. See also Reckey 198931X902508. | S&W |
| 3/23/2001 | Update or Other Action | Review of the RI indicates DRO found in the soil above cleanup levels. No other contaminants found above CLs. Site being managed by the Air Force's compliance group. | Ann Farris |
| 1/21/2003 | Update or Other Action | Problem statement updated. Site will be reevaluated during 2003 for data gaps. Air Force is recommending closure under the restoration program since site is now managed under compliance program. | Ann Farris |
| 5/7/2003 | Site Number Identifier Changed | Changed the Region from 36 to 31. | Former Staff |
| 8/10/2004 | Site Characterization Report Approved | Comment resolution with the Air Force was completed on July 21, 2004 on the 2004 Remedial Investigation/Feasibility Report. The final version of the RI/FS is expected in August 2004. The RI results indicated some low level diesel contamination, but no further migration appears to be occurring. Additional sampling is necessary when the tanks are removed. | Ann Farris |

| 6/22/2006 | Site Characterization Report Approved | SS017-POL Tanks is north of the main installation and contains six inactive 200,000-gallon aboveground storage tanks, each contained in a lined berm. There is also a pumphouse in an unlined area between two of the tanks. The six tanks were closed sometime between the late 1980's and 1997. The 2003 RI sampled the gravel/soil above the liners and found no detectable POL. In the unlined area near the pumphouse, DRO was detected at a maximum of 1750 mg/Kg and GRO maximum of 110 mg/Kg. The RI recommended additional sampling below the liners when the tanks are removed. In preparation for the Clean Sweep demolition this summer, the area under the liners was sampled in the fall of 2005. Each containment area was sampled at the surface and ~5 feet below ground surface in the areas most likely for spills (valve and flange locations). The maximum analytical results were 721 mg/Kg GRO and 5660 mg/Kg DRO. The Air Force is proposing Method II Arctic Zone cleanup levels for the site. The tank area is surrounded on three sides by disturbed tundra (POL Catchment Area LF003 and SD008 on the east, a former sewage lagoon on the north and on the east a gravel road leading to LF001) and on the fourth by a gravel pad that receives some vehicle traffic between the tanks and existing warehouse buildings. DEC agrees that Method Two cleanup levels are appropriate for the site. The use of a Method Two cleanup level will allow GRO and DRO to remain in the soil and the site would be shown as a conditional closure in our Contaminated Sites database. A notation in the database would state that soil with residual levels of GRO or DRO above Method I cleanup levels should not be moved off-site without prior DEC approval and should not be placed in surface water. DEC requests that when the tanks are removed, additional soil sampling and analysis occur to assure that contamination does not remain under the tanks above Method Two cleanup levels. | Debra Caillouet |

| 10/9/2007 | Exposure Tracking Model Ranking | Debra Caillouet | |
| 10/26/2007 | Conditional Closure Approved | The following is the selected remedy for site SS017 under state law: • Site boundaries shall be surveyed to document the location diesel range organics above 230 mg/Kg. • The Base Master Plan for Barter Island will include a statement that ADEC approval is required prior to off-site transportation or disposal of soil containing diesel range organics above 230 mg/Kg. • If the site is transferred, the statement that ADEC approval is required prior to off-site transportation or disposal of site SS017 soil containing diesel range organics above 230 mg/Kg will be included in the property transfer documents. | Debra Caillouet |
| 3/7/2013 | Institutional Control Record Established | Site boundaries shall be surveyed to document the location diesel range organics above 230 mg/Kg. The Base Master Plan for Barter Island will include a statement that ADEC approval is required prior to off-site transportation or disposal of soil containing diesel range organics above 230 mg/Kg. If the site is transferred, the statement that ADEC approval is required prior to off-site transportation or disposal of site SS017 soil containing diesel range organics above 230 mg/Kg will be included in the property transfer documents. | Debra Caillouet |
| 2/29/2024 | Long Term Monitoring Workplan or Report Review | DEC reviewed and approved the 2023 Long-Term Management Report for Barter Island LRRS Sites LF001, SS011, SS013, SS014, and SS022. This report detailed the 2023 annual long-term management inspection of institutional controls/land use controls in place at these sites. Visual inspection results noted that site conditions were largely unchanged from last year's inspections. Minimal site disturbance was reported throughout the installation. IC signage was intact and legible at all locations. SS011 observations included snow covering and some ponding. SS022 observations included more debris and litter present than 2022, appearing to have been minimally disturbed. | Kelly Walker |
