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. |

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. |

Cleanup Plan Approved |
Data Gap Investigation (DGI) for Munition Response Sites: Open Burn/Open Detonation (OB/OD) Range (OD001) and .50 Cal Beach (DU029) and Petroleum, Oil, and Lubricant (POL) Sites: TU559, OT617, and TU568-619-1. After review of the MRSs, AFCEC determined the Open Burn/Open Detonation (OB/OD)
(OD001) MRS and .50 Cal Beach (DU029) MRS require additional data to perform a risk assessment and accurately assess what current and future actions should be taken to make the sites safe for short and long-term human and ecological occupation. This UFP-QAPP and associated appendices serve as the work plan to complete the Data Gap Investigation (DGI) and characterization for the OB/OD (OD001) MRS and the .50 Cal Beach (DU029) MRS. The overall goal of the DGI is to collect sufficient data to address all
contaminants of concern, including any MEC, and provide recommendations on future land use. Three POL sites were determined to need additional surface and groundwater investigation in order to perform a risk assessment for the sites. The three POL sites are TU559, POL site OT617, and POL site TU568-619-1. |

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).

DEC provided comments for the Data Gap Investigation Tech Memo, Revision 01, for Petroleum, Oil, and Lubricant (POL) Sites TU559, OT617 and TU568-619-1; Air Force Military Munitions Response Program (MMRP), Feasibility Study (FS), Proposed Plan (PP), Record of Decision (ROD), Eareckson Air Station-Base Wide, Alaska dated January 2023.This report describes the site characterization investigation activities conducted at the OT617, TU568-619-1 and TU559 sites located at the Eareckson Air Station on Shemya Island, Alaska. At the sites OT617 and TU568-619-1 two monitoring wells were installed (one at each site) and groundwater was sampled. Soil and groundwater samples were analyzed for gasoline-range organics (GRO), diesel-range organics (DRO), residual-range organics (RRO), volatile organic compounds (VOCs), and semi volatile organic compounds (SVOCs). At TU559, surface water was sampled and analyzed for VOCs and polycyclic aromatic hydrocarbons (PAH), total aromatic hydrocarbons (TAH), and Total Aqueous Hydrocarbons (TAqH). The data presented in this report will be evaluated during the preparation of a Decision Document. |

Forty-two different sites were investigated at the Eareckson Air Station located on Shemya Island, Alaska. Groundwater was sampled at nine sites, surface water was sampled at five sites, and sediment sampling was conducted at two sites. Contaminants above cleanup levels remain present at most sites with stable or non-discernable trends. Most land use controls appear to be in good condition and Monitoring and continued inspections were recommended for all sites. |
