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. FT003, the Fire Department Foam Training Area is located in the west central area of the island. Materials disposed of include combustibles, JP-4, waste oil, and POLs at site. Fire training discontinued in late 1980s. Surface water drainages are within the site boundary. Groundwater at 40' below ground surface.

10/21/2010 CERCLA ROD Approved ADEC and USAF representatives have signed the Record of Decision for three Fire Training Grounds at Eareckson Air Station. Based on the results of environmental investigations conducted at the three Fire Training Grounds addressed in this Record of Decision, no CERCLA hazardous substances are considered COCs or COECs and the USAF has determined that no action is necessary under CERCLA to protect public health or welfare of the environment at any of the three Environmental Restoration Sites. ADEC Contaminated Sites Staff concurred that the slelcted remedy complies with state law. Investigations conducted at the FT001, FT002, and FT003 have shown that the contamination is from discharges of petroleum products and, therefore, there is no action necessary under CERCLA and no remedy is being selected under CERCLA. Metals were detected at these three sites; however, there are no antthropogenic sources for these metals at the three fire training sites and these sites will contain a requirement for confirmation sampling for metals to verify that the conclusion that they are not antropogenic in origin. Additionally groundwater and surface water monitoring will be conducted for petroleum products under the State Decision Document. Jonathan Schick
10/21/2010 Update or Other Action The Final Non-CERCLA Decision Document was signed by USAF and ADEC representatives for three Fire Training Grounds at Eareckson Air Station. As lead agent under CERCLA, the USAF has issued a no action ROD under separate cover for these sites - in part because petorleum ius not considered a hazardous substance under the CERCLA petroleum exclusion. Because petroleum is a hazardous substance under state law, these sites need to be addressed under state regulations. At the Fire Department Foam Training Area (FT003) the risks to human health and the environment identified were due to metals (aluminum and chromium) that are believed to be naturally occurring. However, petroleum hydrocarbon levels in the subsurface soils and groundwater exceed ADEC cleanup levels. The selected reemedy at FT003 includes ICs to restrict subsurface activities and monitored natural attenuation of groundwater. Additional sampling and analysis for metals in the site groundwater will also be conducted to substantiate that the metals are naturally occurring. Jonathan Schick
6/25/2011 Update or Other Action This site was included in the 2010 Record of Decision but was not included in the contract for groundwater sampling with the other Fire Training Ground Sites as it was not initially anticipated to be part of the Long Term Monitoring Projects. The ROD determined that the groundwater will be sampled every 2 years to determine if the metals are naturally occurring and to monitor the concentrations of the petroleum constituents. Jonathan Schick
6/25/2012 Update or Other Action No sampling has been conducted at this site but it should be included in the next round of sampling for the Fire Training Ground Sites as determined in the September 2010 Record of Decision. Jonathan Schick
12/1/2012 Update or Other Action The USAF submitted the 2012 Land Use Control Management Plan, which included land use controls for FT03 at Eareckson Air Station. Jessica Morris
10/10/2013 Update or Other Action The ADEC Contaminated Sites Program approved the Environmental Long Term Management Report for several sites. Continued long term monitoring was recommended for FT003. Jessica Morris
1/9/2014 Update or Other Action The ADEC Contaminated Site Program approved the Final Eareckson Air Station Five Year Review Report. The report recommended removing surface metals debris at FT003. Recommedations also included conducting sampling to determine the presence/absence of PFOS/PFOAs. Jessica Morris
8/8/2014 Institutional Control Record Established Institutional Controls established and entered into the database. The ICs include the following 1) The Eareckson AS Base General Base will contain a map indicating restrictions for groundwater use and excavation of soil. Dig permits are issued by the Base Operating Contractor prior to any excavation or well installation at the Base. 2) The USAF will obtain prior concurrence from ADEC to terminate the ICs, modify land use, or allow other actions that might disrupt the protectiveness of the ICs. 3) The ICs will remain in effect until the petroleum hydrocarbons, VOCs, and SVOCs in soil are found to be less that the applicable cleanup levels. Jessica Morris
8/8/2014 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 73820 POL soils from Fire Training Activities. 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
5/12/2015 Meeting or Teleconference Held The ADEC Contaminated Sites Program participated in a project scoping meeting with the US Air Force regarding various sites at Eareckson Air Station. A remedial investigation/feasibility study for multiple compliance and LUST sites is scheduled to occur in 2015/2016. Additional groundwater wells will also be installed for long term monitoring at several IRP sites. Jessica Morris
5/20/2015 Institutional Control Periodic Reporting 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. Jessica Morris
7/9/2015 Institutional Control Update ADEC approved the July 2015 U.S. Air Force Land Use Control Management Plan, Pacific Air Forces Regional Support Center Installations. The plan includes land use controls for FT003 at Eareckson Air Station. Jessica Morris
10/22/2015 Update or Other Action The ADEC Contaminated Sites Program reviewed and commented on a draft scope of work for investigation, remedial process optimization, and long term management studies at several sites for Eareckson Air Station. 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
3/31/2017 Report or Workplan Review - Other The ADEC Contaminated Sites Program approved the Final UFP-QAPP Site Investigation for Perfluorinated Compounds and Long Term Management Studies, Eareckson Air Station. The work plan was approved with the condition that the monitoring program proposed was not sufficient to meet the requirements in the RODs. ADEC requires a work plan for remedy implementation to establish an adequate monitoring program. Jessica Morris
