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. 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. FT002 is the located on the western end of the island and consists of three areas: Aircract Mock-Up Area(MA), Fire Training Area (FTA), and Abandoned Drum Disposal Area (ADDA). The MA was used for fire-fighting training from 1983 to 1988. Cylindrical tanks were configured to resemble an aircraft fuselage, which were located within two concentric earthen berms on asphalt. Petroleum products were used as accelerants during fire training at the site. From 1996 through 2000, a bioventing system was installed and operated to remediate petroleum contamination. The FTA was used for fire training activities from the early 1970s to the mid-1980s. Debris and approximately 1,100 cubic yards of petroleum contaminated soils were removed to a depth of 3 to 4 feet in the late 1980s. The ADDA is a drainage on the north side of the abandoned runway that was used to dispose of drums. Approximately 30 buried drums and 35 to 40 cubic yards of visibly contaminated sediments were removed in 1996.

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 anthropogenic 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 petroleum is 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. The Aircraft Mock-Up Area (MA), Fire Training Area (FTA), and Abandoned Drum Disposal Area (ADDA) together conprise FT002 and cannot support unrestricted use due to petroleum hydrocarbons remaining in place. Institutional Controls with monitored natural attenuation is the selected remedy for FT002-MA. At FT002-FTA, the remedy is ICs to restrict subsurface activities. ICs with MNA of surface water and sediments is the selected remedy for FT002-ADDA. Jonathan Schick
9/27/2011 Site Characterization Report Approved Contaminated Sites Staff submitted a letter to the Air Force's Remedial Project Manager approving the finalization of the Long-Term Monitoring Report with the inclusion of the agreed upon changes including adding the reccommendation for groundwater sampling at the landfill sites in the conclusion section. Jonathan Schick
