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. Building 3005 is located on the northwestern portion of the island, northwest of the Power Plant. The building was previously used as a hazardous waste storage facility, but was shut down in the early 1990s when operations were transferred to the Queen Match Building 1000. Because of the building's use and association with the power plant, and the belief that transformers were stored in the building, an investigation was conducted at the site in 1989. PCB concentrations were detected in the concrete core samples collected within the building (up to 17.5 mg/kg) and soil samples collected adjacent to the building (up to 1.94 mg/kg).

| 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 |
| 11/27/2017 | Site Visit | ADEC staff travelled to Eareckson Air Station for 3 days to conduct site visits and institutional control inspections. 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. A soil removal action is currently scheduled for FY19/20 in conjunction with site SS05. | Jessica Morris |
| 5/2/2018 | Document, Report, or Work plan Review - other | The ADEC Contaminated Sites Program submitted comments on the Draft Remedial Process Optimization Report for Eareckson Air Station. The purpose of the report was to present an evaluation of the effectiveness of the current selected site remedies and make recommendations for optimization of an island-wide monitoring and management program for contaminated sites at Eareckson. 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 |
| 4/27/2022 | Document, Report, or Work plan Review - other | On 4/27/2022 ADEC approved the Eareckson Air Station, Alaska, REMEDIAL PROCESS OPTIMIZATION REPORT dated April 2022. This Remedial Process Optimization (RPO) Report presents an evaluation of the effectiveness of current selected site remedies and makes recommendations for optimization of the IWM Program, as appropriate to establish a more integrated groundwater monitoring program at Eareckson AS. RPO is a systematic approach for evaluating and improving the effectiveness of site remediation without increasing site risk. This RPO Report presents a site-by-site evaluation of effectiveness of the sites selected remedy and provides recommendations to: • Streamline groundwater monitoring. • Develop a holistic approach to site management. • Maintain the remedial action objectives (RAOs) set forth in established Record of Decisions (RODs) and Decision Documents (DDs). | Daniela Fawcett |
