Problems/Comments

Eareckson AS is situated on Shemya Island, approximately 1,500 miles southwest of Anchorage, Alaska at the westernmost tip of the Aleutian Islands. Shemya Island is part of the Near Islands group of the Aleutian Archipelago. The U.S. Army first developed facilities on Shemya Island in 1943 to support operations against the Japanese occupation forces on the nearby islands of Attu, Agattu, and Kiska. In 1954, the site was deactivated, and was turned over to the Civil Aeronautics Authority in 1955. In 1958, the Air Force returned to Shemya Island to support various Air Force and Army strategic intelligence gathering activities. It has remained active in this capacity to the present. In 1995, the station was downsized and reverted to caretaker status and a private operation and maintenance contractor took control of the facility under contract to the Air Force. Shemya Island is owned by the U.S. Government and is under the jurisdiction of the United States Fish and Wildlife Service (USFWS) as part of the Alaska Maritime National Wildlife Refuge. SS010 consists of a Vehicle Refueling Area: former Building 605, Building 614, and five USTs: 605-1, 605-2, and 605-3 (removed in 1993), 614-1, and 614-2 (removed in 1997). This site is located in the west-central portion of the island (Figure 2-1). SS010 has been referred to in the past as ST043, ST010, ST10, and PS-6. The buildings and associated USTs have been used to support the repair and maintenance of motor vehicles. The USTs included: a 1,000-gallon waste oil tank (605-1), a diesel tank of unknown volume (605-2), an oil/water separator tank (605-3), a 1,000-gallon diesel fuel tank (614-1), and a 500-gallon waste oil tank (614-2) (USAF, 1998). Specific dates of operation are not known. The site also contains several drum storage areas. TPH to 27,000 mg/kg. Lead to 305 mg/kg and Zinc to 239 mg/kg. Barium to 356 mg/kg.

The conditions for the UFP-QAPP are as follows: 1) We do not object to the long term monitoring work being completed as outlined in the UFP-QAPP; however ADEC cannot concur that efforts will be counted towards meeting the end point criteria outlined in the decision documents until an adequate monitoring program has been established. 2)The QAPP states that field screening results and field observations will be used to determine additional groundwater monitoring well locations. These locations should to be coordinated with ADEC. 3) The leaking underground storage tank (LUST) sites at Eareckson Air Station will need to be characterized and closed in accordance with LUST regulations that are included in 18 AAC 78. 4) The scope of work for this investigation may not be sufficient to fully characterize the sites listed in the work plan, and additional investigation may be necessary.	Jessica Morris

7/29/2010

Update or Other Action

ADEC submitted comments on the Draft Remedial Field Investigation at 12 Environmental Restoration Program Sites (Addendum) which included an island wide background metals sampling event.

Additionally the report detailed the follow-on remedial investigation of the PCB impacts at SS012.

Jonathan Schick

Samples were collected around the perimeter of the previous investigations and also down the slope that drops from the site to the north/northwest. Also the addendum detailed the collection and calculation of background metals concentration from across the island at locations not associated with known contaminated sites.

Site Characterization Workplan Approved

The ADEC Contaminated Sites Program conditionally approved the 2016 Uniform Federal Policy - Quality Assurance Project Plan (UFP-QAPP) for Site Characterization at 14 Former POL Sites, Eareckson Air Station, Shemya Island, Alaska. The conditions for the UFP-QAPP are as follows: 1) We do not object to the long term monitoring work being completed as outlined in the UFP-QAPP; however ADEC cannot concur that efforts will be counted towards meeting the end point criteria outlined in the decision documents until an adequate monitoring program has been established. 2)The QAPP states that field screening results and field observations will be used to determine additional groundwater monitoring well locations. These locations should to be coordinated with ADEC. 3) The leaking underground storage tank (LUST) sites at Eareckson Air Station will need to be characterized and closed in accordance with LUST regulations that are included in 18 AAC 78. 4) The scope of work for this investigation may not be sufficient to fully characterize the sites listed in the work plan, and additional investigation may be necessary.

Institutional Control Compliance Review

The Alaska Department of Environmental Conservation (ADEC) Contaminated Sites Program received a copy of the Final Long Term Monitoring and Institutional Controls Inspection Report for Eareckson Air Station. The report is accepted as final documentation of the field activities. The report is approved with the conditions noted in the ADEC’s comments 1/8/19 letter. The field efforts completed are not considered sufficient to meet the overall long term monitoring requirements outlined in the site records of decision and regulations for closure end point criteria. ADEC is working with the USAF to develop a more efficient island-wide long term monitoring strategy for Eareckson Air Station.

The purpose of this project is to continue environmental long-term management at multiple sites at Eareckson AS, Alaska. The objectives of this project were to conduct groundwater sampling at eight sites, surface water sampling at four sites, sediment sampling at three sites, conduct IC inspections at 19 sites, and conduct an assessment of necessary repairs at LF026. The assessment of LF026 is documented in a separate technical memorandum; this LTM report presents the findings of the IC inspections and the results of groundwater, surface water, and sediment sampling.

Forty-two different sites were investigated at the Eareckson Air Station located on Shemya Island, Alaska. Groundwater was sampled at nine sites, surface water was sampled at five sites, and sediment sampling was conducted at two sites. Contaminants above cleanup levels remain present at most sites with stable or non-discernable trends. Most land use controls appear to be in good condition and Monitoring and continued inspections were recommended for all sites.
