Problems/Comments
On August 13, 2006 approximately 50 gallons of Jet-A (Diesel #1) fuel spilled from the overfill of an aboveground storage tank onto a concrete pad and within the Lake Hood shoreline and dock area. Reporting, containment, and recovery efforts were begun immediately. On September 25, 2006 Shannon and Wilson conducted soil sampling to characterize the spill to gravel and soil between the tank and shoreline of Lake Hood. On October 23, 2006 Shannon & Wilson directed the excavation (approx. 7' X 24' X 1.5' deep) of 13 cubic yards of contaminated soil which were subsequently transported to Alaska Soil Recycling. Excavation was stopped due to shallow groundwater (lake aquifer) and conduit line within excavation pit. The department received Shannon & Wilson's Release Investigation and Site Cleanup Report. Elevated levels of GRO and DRO remain near the south end of the excavation and benzene was present in samples from three discrete locations.

| 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. | Todd Blessing |
| 4/16/2008 | Update or Other Action | DEC staff reviewed a work plan titled “Groundwater and Surface Water Evaluation, RUSTs Flying Service 50-Gallon Jet-A Fuel Spill, 4525 Enstram Circle, Anchorage, Alaska.” This work plan was prepared by Shannon and Wilson Inc. (S&W), dated March 28, 2008 and received at DEC’s Anchorage Office on April 14, 2008. Within the work plan, S&W proposed to do the following: Install and sample three monitor wells; install and sample two passive diffusion samplers; collect soil samples during monitor well installation; and issue a summary report. DEC staff issued a letter on April 16, 2008 approving of the work plan with the following modifications: 1. The three monitor wells will be installed at locations determined by CSP to be appropriate following a meeting to discuss site details; 2. S&W will develop a conceptual site model according to CSP guidance; 3. S&W will complete a data review CSP checklist for each laboratory data deliverable; 4. S&W will deliver a final report to CSP within 60 days following completion of field work; and 5. S&W will notify CSP at least two days prior to commencement of field work to allow CSP staff to inspect the work activities. | Todd Blessing |
| 1/6/2009 | Cleanup Complete Determination Issued | The cleanup actions to date have served to excavate and adequately remove the majority of contaminated soil from the site. Groundwater and surface water are not believed to be contaminated above applicable 18 AAC 75 Method Two or Table C cleanup levels following ADEC’s review of Shannon and Wilson’s “Site Characterization 4525 Enstram Circle Anchorage, Alaska” report, dated November 2008. Furthermore, ADEC has determined that groundwater is not a current or reasonably expected future source of drinking water in accordance with 18 AAC 75.350. Based on the information available, ADEC has determined no further assessment or cleanup action is required. There is no longer a risk to human health or the environment, and this site will be designated as closed on the Department's database. Although a Cleanup Complete determination has been granted, ADEC approval is required for off-site soil disposal in accordance with 18 AAC 75325(i). Since this site has not met the most conservative soil cleanup levels, this letter does not serve as your approval for future off-site movement and disposal of soil associated with this release. It should be noted that movement or use of potentially contaminated soil in a manner that results in a violation of 18 AAC 70 water quality standards is unlawful. This determination is in accordance with 18 AAC 75.380(d) and does not preclude ADEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment. | Todd Blessing |
