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. |

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.
