Problems/Comments
One 10,000-gallon underground storage tank (UST) containing Jet B, the associated fuel dispenser, and 70 cubic yards of contaminated soil were removed from an area just west of ERA Hangar #2 at the Anchorage Airport. The contaminated soil was stockpiled at ERA Hangar #1. The tank was part of UST Facility #1476. All other UST under that facility number were located at Hangar #1 and managed as a separate site.

| 5/8/2001 | Document, Report, or Work plan Review - other | ADEC received a report indicating that the suspected 300-gallon generator tank did not exist and detailing the assessment of the 100-gallon waste oil tank. There was no contamination related to the waste oil tank, though there was evidence of a previous spill with diesel range organics contamination that did not exceed 498 mg/Kg. Most of the contaminated soil from the excavation (20 cubic yards) was removed and disposed at Alaska Soil Recycling. The 100-gallon underground storage tank was closed in place. The closure of the tank was approved by the ADEC. | Lisa Krebs-Barsis |

| 7/3/2007 | Institutional Control Record Established | 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. | Colleen Deal |

| 2/12/2015 | Cleanup Complete Determination Issued | The remaining drinking water wells at Hangar 1 and Hangar 2 were decommissioned in 2010 and 2011. A review of the files indicate that, because of the 18 AAC 350 determination and the decommissioning of the drinking water wells, the site was eligible for closure with no additional work. | Lisa Krebs-Barsis |
