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 a No Further Action letter could be issued for this sites based on the level of contamination found during the tank decommissioning (excavation confirmation samples only). However, the site assessment report indicates piping associated with the tanks was pulled but not assessed for contamination. 18 AAC 78.090 requires piping to be assessed for contamination with a minimum of one confirmation sample collected based on proper field screening. If piping confirmation samples were collected and analyzed, this data needs to be submitted to ADEC. Because of the unregulated status of some of these tanks or the close proximity of the tanks to the buildings/equipment they supplied fuel to, sampling could be waived if the Air Force would supply ADEC with information regarding the type of piping used. ADEC specifically requested information on the material of construction, total length on piping, and whether the piping was one continuous piece or made of sections. |

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. |
