Problems/Comments
FAC ID 0-000857: FAA Tank # 4-J-1/EE-4J1, also refered to as tank # EE451. Tank was abandoned in place on July 19, 1995. Dick Farnell former ADEC staff assigned. FAA is evaluating cleanup options. This tank was regulated under the Leaking Underground Storage Tank (LUST) program, and was closed in that program on 7/10/1995. The bottom of the tank sits in a depression chipped into bedrock. Contamination was released directly to the subsurface from the UST supply and return lines. Approximately 0.25 cubic yards of contaminated soil in this area was removed and thermally treated. The sample collected below the supply and return lines had a DRO concentration of 2,600 mg/kg and an ethylbenzene concentration of 9.6 mg/kg, both of which exceed the method two migration to groundwater cleanup levels. In addition, the method detection limit for benzene in this sample (0.88 mg/kg) was greater than the migration to groundwater cleanup level. The decommissioning report stated that, given the 200’ bgs depth to groundwater, the small mass of remaining contamination will not migrate to groundwater.
Action Information

|---|---|---|---|
| 11/1/1995 | Underground Storage Tank Site Characterization or Assessment | In-place SA completed. Product line removed. One sample collected from along side of tank and one from 30' copper line. Contamination exceeding level "D" found in piping sample. | Former Staff |
| 11/1/1995 | Leaking Underground Storage Tank Release Confirmed - Petroleum | LUST Site created in CSP for source area ID 77932 ADD; Diesel and gasoline contamination from UST. | Former Staff |

| 11/2/1995 | Leaking Underground Storage Tank Cleanup Initiated - Petroleum | LCAU; Corrective action underway. Options being evaluated. : LCAU date changed DB conversion | Former Staff |
| 7/1/2005 | Document, Report, or Work plan Review - other | reviewed decommissioning report to determine if additional work is warranted or if site is ready for closure. | Sharon Richmond |
| 7/28/2005 | Update or Other Action | Contaminated sites staff met with the Federal Aviation Administration (FAA) to discuss closure of multiple facilities at the Fairbanks International Airport. Thirty two underground storage tanks, three floor drains, and twenty four transformers were decommissioned in the mid-1990s. Release investigations indicate that most areas appear to qualify for no further remedial action planned (NFRAP) status. The extended meeting ws very productive and the FAA and DEC intend to continue with this approach for achieving site closures. | Sharon Richmond |

| 1/20/2015 | Update or Other Action | In 2/26/97 letter, ADEC responded that further information, testing, or action is required at this site. A Remedial Action (RA) plan will be developed in FY21, followed by the RA in FY22. | Keri DePalma |
| 9/9/2015 | Update or Other Action | The Alaska Department of Environmental Conservation (DEC) completed a comprehensive review of the historical, closed, and currently active contaminated sites at the Federal Aviation Administration (FAA) Station – Fairbanks International Airport (FIA), Alaska. Following this review, DEC determined the site status of each area of concern (AOC), and developed a decision document to record these determinations. This includes the closure of multiple AOCs, some with the implementation of institutional controls. The current status for each AOC, the history of each site, contaminated sites program database updates, and the site status determinations are contained within this decision document, which was sent to FAA on this date. | Monte Garroutte |
| 12/29/2015 | Cleanup Complete Determination Issued | The remaining cumulative carcinogenic risk at this site from benzene (0.88 mg/kg) and ethylbenzene (9.6 mg/kg) was calculated to be 2x10-6, and the cumulative hazard index is 0.01, both below the DEC risk standards. Therefore, based on a review of the environmental record, DEC has determined that residual contaminant concentrations do not pose a cumulative human health risk at this area of concern | Joy Whitsel |
Contaminant Information
| Name | Level Description | Media | Comments |
|---|---|---|---|
| GRO | < Method 2 Most Stringent | Soil | |
| DRO | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | given the 200’ bgs depth to groundwater, the small mass of remaining contamination will not migrate to groundwater. |
| Benzene | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | Benzene and ethybenzene remain at the site above migration to groundwater cleanup levels, though below inhalation levels. Cumulative risk does not exceed carcinogenic or non-carcinogenic standards |
| Ethylbenzene | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | Benzene and ethybenzene remain at the site above migration to groundwater cleanup levels, though below inhalation levels. Cumulative risk does not exceed carcinogenic or non-carcinogenic standards |
