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 the UST diagrams submiteed as part of the UST site assessment reports indicate there is a dispenser island associated with the three USTs. The site assessment narrative did not discuss the removal of the fuel island or the collection of soil confirmation samples from the piping and dispenser areas. The requirement to sample was discussed in a April 13, 1999 meeting. At that time, the site assessment contractor stated they thought the dispensers were located on tip of the tanks and were removed during the tank closures. The contractor was to verify the dispensers were removed by reviewing the decommissioning field notes, and report their findings in the final site assessment report. Photos 35 & 36 in Appendix "A" show three dispensers located away from the UST excavations. Figure 2.14-1 indciates the dispensers were located approximately 25 feet southeast of the tank excavations. ADEC requested the Air Force to submit a work plan to assess the piping runs and the dispenser island associated with these USTs. |

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. |

Site Characterization Workplan Approved |
The ADEC Contaminated Sites Program approved the Final Addendum Addendum Uniform Federal Policy – Quality Assurance Project Plan (UFP-QAPP) for Site Characterization at 13 Former POL Sites, Eareckson Air Station, Sheyma Island, Alaska. The QAPP Addendum was approved with the following conditions: 1)ADEC requests weekly field meetings during the effort. 2)the LUST regulations in 18 AAC 78 still need to be achieved. 3) the scope of work for this effort may not be sufficient to fully characterize the sites, and additional characterization may be necessary.

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).
