Problems/Comments
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. This site is the location of tank 615-1, which was a heating oil tank used for the transient dormitory, building 615. DRO contaminated soil was found during the removal of the tank. Contaminated soil from the removal was used to subsequently backfill the excavation. There is currently no documentation regarding the associated piping runs from the tank to the building, and no soil sampling was conducted to characterize this area. Please note that this site was previously identified as part of Site ST33, ADEC File Number 2649.26.014, Hazard ID 31.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 7/24/1997 | Site Added to Database | Former Staff | |
| 7/24/1997 | Leaking Underground Storage Tank Cleanup Initiated - Petroleum | UST removed from the ground. | Tim Stevens |
| 7/24/1997 | Leaking Underground Storage Tank Release Confirmed - Petroleum | LUST Site created in CSP for source area ID 77813 Contaminated soil found during UST closure. | Former Staff |
| 2/5/1999 | Update or Other Action | ADEC project manager sent the US Air Force a letter requesting a release investigation be conducted at the site to determine the full extent of contamination found during the SA. DRO levels of 1,100 mg/kg found. Contaminated soils excavated from UST excavation was used as backfill material at this site. | Tim Stevens |
| 1/12/2000 | Underground Storage Tank Site Characterization or Assessment | ADEC received the site assessment report. This site is one of 43 UST SA reports contained in the April 1998 Draft " Project Report" Eareckson AS. Final report dated June 11, 1999 and entitled "Project Report - UST Site Assessment Reports, AST Removal Reports, and Environmental Compliance Activities." Associated ADEC/STP comment letter dated January 12, 2000 prepared by Timothy Stevens. ADEC comment letter states that based on information and laboratory data contained in the site assessment reports, tank 615-1 (ADEC #72) will need to have a release investigation done to determine the vertical and horizontal extent of the contamination found during the closure process. | Gretchen Pikul |
| 4/11/2007 | Exposure Tracking Model Ranking | Initial ETM Ranking | Jill Taylor |
| 1/11/2012 | Update or Other Action | The ADEC Contaminated Sites Program sent a letter to the USAF stating that additional investigation is required to delineate the extent of DRO impacts and to characterize the pipeline that ran from the tank into Building 615. | Jonathan Schick |
| 9/25/2014 | Meeting or Teleconference Held | A project records review and scoping meeting was held between the ADEC and USAF. Additional investigation work is planned for this site during 2015. | Jessica Morris |
| 10/22/2015 | Update or Other Action | The ADEC Contaminated Sites Program reviewed and commented on a draft scope of work for investigation, remedial process optimization, and long term management studies at several sites for Eareckson Air Station. | Jessica Morris |
| 8/31/2016 | Site Characterization Workplan Approved | The ADEC Contaminated Sites Program conditionally approved the 2016 Uniform Federal Policy - Quality Assurance Project Plan (UFP-QAPP) for Site Characterization at 14 Former POL Sites, Eareckson Air Station, Shemya Island, Alaska. The conditions for the UFP-QAPP are as follows: 1) We do not object to the long term monitoring work being completed as outlined in the UFP-QAPP; however ADEC cannot concur that efforts will be counted towards meeting the end point criteria outlined in the decision documents until an adequate monitoring program has been established. 2)The QAPP states that field screening results and field observations will be used to determine additional groundwater monitoring well locations. These locations should to be coordinated with ADEC. 3) The leaking underground storage tank (LUST) sites at Eareckson Air Station will need to be characterized and closed in accordance with LUST regulations that are included in 18 AAC 78. 4) The scope of work for this investigation may not be sufficient to fully characterize the sites listed in the work plan, and additional investigation may be necessary. | Jessica Morris |
| 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. | Jessica Morris |
| 2/23/2018 | Document, Report, or Work plan Review - other | The ADEC Contaminated Sites Program provide comments on the Draft Site Characterization Report at 13 Former POL Sites, Phase I, Eareckson Air Station. | Jessica Morris |
| 2/23/2018 | Update or Other Action | The ADEC Contaminated Sites Program submitted comments on the Draft Site Characterization Report at 13 Former POL Sites, Phase I, Eareckson Air Station, Alaska. | 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 | 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). | Daniela Fawcett |
