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 Aleutian Islands National Wildlife Refuge. Site ST39 consists of several USTs near Building 110: USTs 110-1 through 110-4. Diesel fuel potentially disposed, dates of operation 1960s to 1990s. This site consists of three USTs which have been removed. Tank 110-1 was not located; may already have been removed.

11/16/2007 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 discuss the plan moving forward for Records of Decision and remedial alternatives. Jonathan Schick

2/20/2008 Exposure Tracking Model Ranking Initial ranking with ETM completed. Jonathan Schick
10/20/2008 Record of Decision ADEC recieved a copy of a Final Record of Decision for SS07 and ST039 both a CERCLA ROD and a non-CERCLA Decision Document were submitted by the USAF for the state's review and signature. The copies sent to the state have already been signed by the USAF Colonel. Jonathan Schick
11/17/2008 Record of Decision ADEC signed the CERCLA ROD for sites SS007 and ST039. The signature of the ADEC documents the USAF and ADEC's approval of the determination of no further action required under CERCLA for ERP sites SS007 and ST039 at Eareckson AS, Alaska. This decision may be reviewed and modified in the future if new informaiton becomes available that indicates the presence of previously undiscovered contamination or exposure routes that might cause an unacceptable risk to human health or the environment. Jonathan Schick
2/12/2009 Record of Decision ADEC staff (J. Halverson) signed the Non-CERCLA Decision Document for the West End Oil/Water Separator Ponds (SS007) and Underground Storage Tanks at Building 110 (ST039) at Eareckson Air Station. The signing of this Decision Document was delayed because of disagreements over monitoring only surface water and sediment at the SS007 site, which is an engineered wetland designed to slow the flow and capture contaminants before the surface water discharges into the marine environment. The State wanted to ensure that the groundwater and soils in the area were adequately characterized before a decision could be agreed upon. The USAF and ADEC concurred that the groundwater and subsurface soil impacts in the area would be characterized in the ongoing RI work at ST046, a former large tank farm just upgradient of the engineered wetland. The signature page was modified with the following language, “ST046 is upgradient from SS007 and is suspected to be a source for contamination w/in SS007. Due to uncertainty on groundwater/surfacewater interaction, the sources of petroleum contamination w/in SS007, the extent of soil contamination , and the fact that this Decision Document is focused on impacts to surface water /sediment, ADEC reserves the right to request additional characterization or cleanup in the future, if these issues are not adequately addressed in the ST046 ROD/Decision Document.” The original signature page was mailed to the 611th CES and a copy was inserted to the State’s copy for our records.
