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 3051-9 (ADEC #35) will need to have a release investigation done to determine the vertical and horizontal extent of the contamination found during the closure process. |

Cleanup Complete Determination Issued |
Contamianted Sites Staff submitted a letter to the USAF Remedial Project Manager stating that the LUST Site Tank 3051-9 will be administratively closed on ADEC's database as the residual contamination from this LUST is within the site bondaries of IRP site ST044 adn the contamianted media will be managed under that site moving forward.

Site Reopened |
This site was administratively closed because it was planned to be managed under site ST044. However, the Record of Decision for site ST044 was signed in February 2014 and did not address Tank 3051-9. Site ST044 is limited to the area immediately surrounding UST 3051-1. |

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. |
