Problems/Comments

Building 525 is not an official IRP source area. Verbal reports indicate that a fuel-handling facility with a history of leaks was reportedly previously located in the Building 525 area. Dates of operation are unknown. JP-8 fuel lines (which formerly carried JP-4), potentially other fuel sources, and possible solvent sources are located upgradient of the area. Details pertaining to the former use of solvents in the area are not available. Building 525, a newly constructed vehicle maintenance complex, the new gas station, and the POL vehicle parking area are currently located in this area. A 300-gallon diesel UST was located adjacent to the west side of Building 525. This tank has reportedly been removed. Currently, an aboveground diesel fuel tank is located in the Building 525 area. 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. 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. 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. Longitude is east of Greenwich. RCRA EPA ID#s AK9570028705 Hazardous waste activity: generator 2, storer and burns hazardous waste fuel in burner. AK7570000151 Cleanup.

Jonathan Schick
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. The State;s main concern with the report is the statistical analysis of the background metals as the 95% UCL was used as the background concentration instead of the UPL or UTL. Additionally the report detailed the follow-on remedial investigation of the PCB impacts at SS012.	Jonathan Schick
11/3/2010	Site Characterization Report Approved	Contaminated Sites Staff issued a letter to the USAF approving the Final version of the Remedial Field Investigation at 12 Environmental Restoration Program Sites Remedial Investigaion Report Addendum.

3/17/2014	CERCLA ROD Approved	The ADEC Contaminated Site Program approved the February 2014 Record of Decision for SS010, SS023/ST035, SS025, ST046, ST050, and ST051. The selected remedy for ST051 was Long-term Management with Institutional Controls to restrict access to or inappropriate use of soil and groundwater. The remedy also includes Monitored Natural Attenuation (MNA) of contaminants in groundwater in sampling events conducted every 2 years.	Jessica Morris
8/27/2014	Long Term Monitoring Established	The ADEC Contaminated Sites Program approved the Final Work Plan for Environmental Long Term Monitoring and Site Inspections ((FT001, FT002, FT003, OT048, SS007, LF015, LF018, LF024, LF026, SS010, SS023, ST035, SS025, ST009, ST044, ST046, ST050, ST051) and Limited Site Characterization (Building 3055 Area) at Eareckson Air Station, Alaska. This scope of work is not sufficient to meet the long term monitoring objectives outlined in the most recently established RODs. The USAF will hold a scoping meeting with ADEC to plan additional well installation to meet these long term monitoring requirements.	Jessica Morris
5/20/2015	Institutional Control Compliance Review	The ADEC Contaminated Sites Program approved the Final Report for Environmental Long Term Monitoring and Site Inspections (FT001, FT002, FT003, OT048, SS007, LF015, LF018, LF024, LF026, SS010, SS023, ST035, SS025, ST009, ST044, ST046, ST050, ST051) at Eareckson Air Station, 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.	Jessica Morris
11/14/2016	Site Visit	ADEC staff travelled to Eareckson Air Station for 4 days to conduct site visits and become familiar with the ecology and topography of the island. Site visits were conducted to all pertinent sites and meetings were held to with ADEC and USAF to discuss a path forward for the sites.	Jessica Morris

ADEC had numerous comments on the document, and requested a project team meeting to further discuss a more effective and efficient program at Eareckson.	Jessica Morris
1/8/2019	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.	Jessica Morris

Update or Other Action

ADEC participated in a meeting regarding 2002 Missile Defense program field work. A previously unknown UST was discovered during excavation activities for the Defense Satellite Communication System structure (in vicinity of this site). Approximately 15,000 cubic yards of contaminated soil was removed and is currently in long term stockpiles located on abandoned runway B. Based on the limited construction timeframe, the soil was removed in lieu of in situ remediation. According to the preliminary data, the most elevated DRO level detected in the contaminated soil is 1,800 mg/kg. Follow-on activities will include: (1) Missile Defense will program a study to determine the best possible management or treatment options for the contaminated stockpiles; (2) A comprehensive report detailing the 2002 project will be issued; and (3) An Operation and Maintenance plan will be developed for management of the contaminated soil stockpiles until a final decision can be made on management or treatment options. An Air Force Memo outlines this meeting.

12/11/2003

Update or Other Action

Air Force has reprioritized all remaining sites as medium and low priority due to security on island, no local community affected, and no current human health or ecological risk determined by risk assessment and investigations. Since the Air Force is required to complete all high priority projects by 2007, the Eareckson projects are being placed further in the outyears. See ADEC e-mail dated December 11, 2003 regarding sites ST46, SS23, SS25, ST50, and ST51 and requested monitoring during the interim years.
