Problems/Comments
Diesel contamination from a 1,000-gallon heating oil underground storage tank (UST). UST was removed in 1991. Contamination (5,100 parts per million (ppm) diesel range organics (DRO) and 19.7 ppm benzene, toluene, ethylbenzene, and xylenes (BTEX) has migrated under the C Concourse. This release is in proximity to AIA C Concourse release (Reckey #1997210113101).

| 7/3/2007 | Update or Other Action | In accordance with 18 AAC 75.350, ADEC has determined that the unconfined groundwater (above the Bootlegger Cove Formation) at the Anchorage International Airport (AIA) is not a current or future drinking water source. This determination is subject to the following conditions: 1. It applies only within the Airside and Commercial RMZ’s, as described in the Airport-Wide Remediation Management Plan. It does not apply within the Ecological RMZ. 2. It does not establish alternative cleanup levels within those zones but allows ADEC to use the determination in making decisions in accordance with 18 AAC 75.345(b)(2) - (3). 3. Any drinking water wells located on AIA property must be properly abandoned in accordance with ADEC decommissioning procedures within two years of this decision. 4. AIA shall prohibit the installation of any water wells, used for drinking, cooling, washdown, or any other purposes, on the AIA either through 17 AAC 42.410 (b) (27) of the airport leasing regulations or in their individual lease agreement documents. 5. The existing AIA water well used to maintain the water level in Lake Hood is not considered a drinking water well. However, AIA is responsible for determining its wellhead protection area and ensuring that it maintains levels at or below 18 AAC 75.345 Table C values, unless otherwise approved by ADEC. March 19, 2007 Amendment: DEC has determined that the shallow groundwater along the Lake Hood shoreline is not a current or future drinking water source in accordance with 18 AAC 75.350. Therefore, the March 2001 groundwater use determination is amended to include the shallow groundwater in the Ecological RMZ in that determination. | Lisa Krebs-Barsis |
| 12/30/2014 | Update or Other Action | Updated the latitude and longitude. | Lisa Krebs-Barsis |
| 12/31/2014 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 72191 Heating Oil Spill. | Lisa Krebs-Barsis |
| 1/7/2015 | Cleanup Complete Determination Issued | ADEC has determined that the Tank 8 site cleanup is complete after reviewing the files and considering higher cleanup levels now applicable rather than cleanup levels that were applicable when the site was discovered. Migration to groundwater soil cleanup levels and groundwater cleanup levels do not apply to this site because of the 18 AAC 75.350 determination. | Lisa Krebs-Barsis |
