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. SS005 is located in north-central Shemya, and was the location of a former oil spill at the old Cobra Dane power plan. A surface water ditch drained this area, and eventually discharged over the bluff. Surface soils are impacted with oils, lubricants, solvents, PCBs.

12/4/2008 Update or Other Action ADEC recieved a copy of a Work Plan Addendum for 6 sites including SS005, ST009, SS012, SS023, SS025, and ST050. They are scheduled to begin work to further delineate the extent of contamination at these 6 sites on Monday December 8, 2008. Jonathan Schick
12/9/2008 Update or Other Action ADEC Staff issued a letter to the 611th indicating that the Work plan Addendum for 6 sites at Eareckson AS would not be approved. We are not able to approve this Work plan Addendum at this time because of the one day turnaround time and the lack of information provided to render decisions applicable to this sampling program. Upon reviewing this document several questions arise about the proposed field activities. Without having an opportunity to review the data collected from the Remedial Field Investigation performed this summer, we cannot determine the appropriateness or comprehensiveness of the proposed sampling strategy. Therefore, by proceeding with this Work plan Addendum without the ADEC’s approval, there is a chance that we will not concur with the conclusions and recommendations derived from this Remedial Field Investigation. Jonathan Schick
3/26/2009 Update or Other Action ADEC staff recieved a draft version of the Analytical Data Report for the 12-site Remedial Investigation at Eareckson AS. A Draft Risk ASsessment Work Plan was submitted at the same time for our review. Jonathan Schick

7/29/2010 Update or Other Action ADEC submitted comments on the Draft Remedial Field Investigation at 12 Environmental Restoration Program Sites (Addendum) which included an island wide background metals sampling event. The State;s main concern with the report is the statistical analysis of the background metals as the 95% UCL was used as the background concentration instead of the UPL or UTL. Additionally the report detailed the follow-on remedial investigation of the PCB impacts at SS012. Jonathan Schick
11/3/2010 Site Characterization Report Approved Contaminated Sites Staff issued a letter to the USAF approving the Final version of the Remedial Field Investigation at 12 Environmental Restoration Program Sites Remedial Investigaion Report Addendum. The report detailed the additional investigation of the extent of PCB impacted soils at SS012 the Old White Alice Site at Eareckson Air Station. Samples were collected around the perimeter of the previous investigations and also down the slope that drops from the site to the north/northwest. Also the addendum detailed the collection and calculation of background metals concentration from across the island at locations not associated with known contaminated sites. Jonathan Schick

5/1/2023 Document, Report, or Work plan Review - other DEC provided comments for the Draft Final Report Eareckson Air Station Remedial Action-Construction Sites SS005 and SS012 Eareckson Air Station, Alaska, dated March 2023. This report describes the excavation and soil removal activities, conducted during the 2021 and 2022 field seasons at the SS005 and SS012 sites, located at the Eareckson Air Station on Shemya Island, Alaska. Approximately 5329 cubic yards of soil were excavated, characterized, and segregated based on their analytical results. At SS005 the removal actions were focused on two historical hot spot locations P1B-A1 and HC03. Metal contaminated soil remains at P1B-A1 and no contamination remains at HC03. Further excavation at P1B-A1 is not recommended due to the presence of existing infrastructure. At SS012 multiple areas with soil contaminated with polychlorinated biphenyls (PCBs) remain, and further removal actions are recommended for this site. Ginna Quesada
