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. Scrap Metal Landfill. LF28 occupies an area of about 3 acres located adjacent to the active municipal solid waste landfill. It is bordered on the west by a road, and on the east by grass-covered cliffs that slope down to the Pacific Ocean. LF28 was used to dispose of scrap metal and various domestic wastes until 1988. Aerial photographs and historical maps indicate that materials were being disposed of at this site as early as 1971, but the date when the site first started being used in unknown. The landfill was used primarily in the late 1980s when scrap metal was collected and buried there as part of an earlier Air Force cleanup effort. The surface was graded sometime after 1988 and is currently a series of hummocks with broken concrete. Since 1988, environmental studies have been conducted at LF28 to characterize the nature and extent of contaminants. The studies included collecting samples of soil, groundwater, and surface water. The samples were analyzed for petroleum hydrocarbons, VOC, SVOC, pesticides, PCB dioxins, and metals. The selected remedy is Institutional Controls with NFRAP status to be noted in the state land records and Air Force comprehensive map and master plan. A 5-year review will be conducted to ensure remedy is protective, and to evaluate landfill cover, institutional controls, and general site conditions. In addition to ICs, a land survey will be performed and recorded, any uncovered debris will be removed with additional cover placed, and 3 inspections prior to 5-year review.

Gretchen Pikul
10/27/2006 Update or Other Action The ADEC Contaminated Sites Program sent a letter to the USAF approving the overall selected remedy in the 2005 Record of Decision for Scap Metal Landfill (LF028). The ROD stipulates no further action under CERCLA, insitutional controls, and five-year reviews. The department did not sign the ROD, however, due to disagreement on specific wording in the document. Jennifer Roberts
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

11/17/2010 CERCLA ROD Periodic Review Contaminated Sites staff recieved a Draft version of the Five-Year Review for Site LF028, a scrap metal landfill on Eareckson Air Station. The landfill was active until 1988. The Record of Decision was signed by the Air Force in January of 2006 and ADEC concurred with its contents in October 2006, though the ROD was not signed by ADEC. This Five-Year Review details the site inspection conducted in the summer of 2010 and the photos indicate that some metal solid waste has protruded through the cap material and should be removed as an action item in the follow-up from this Five Year Review. Jonathan Schick
12/22/2010 CERCLA ROD Periodic Review Contamianted Sites Staff submitted a letter to the Air Force Remedial Project Manager with comments on the Draft 5-year review document for the selected remedy for LF028. There is some confusion about the association between LF027 and LF028 as they are adjacent ton each other but managed separately. LF027 is under the compliance program and LF028 is manged under the restoration program, though only LF028 is listed as a contaminated site. Solid Waste Division of the ADEC may take over control of this site and the maintainence of the cap and periodic reviews and inspections since there is groundwater monitoring associated with the closure of LF027, but not LF028. Jonathan Schick
5/27/2011 CERCLA ROD Periodic Review Contaminated sites staff sent a letter to the management at the 611th CES at the Air Force explaining our concerns with the status of the site and its Institutional Controls and the metal remaining at the site and what will need to be accomplished in the future at the site.

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. 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
7/5/2019 CERCLA ROD Periodic Review DEC provided comments to the U.S. Air Force on the "Five-Year Review Report and Period Review for Eareckson Air Station, Shemya Island, Alaska, Draft” dated November 2018 on July 5, 2019. Melinda Brunner
4/27/2022 Update or Other Action 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).
