Remedial excavation is proposed at sites TU077, SS079, and CG517 to remove up to 6,500 cubic yards (cy) of POL-contaminated soil in the vadose zone in order to eliminate the potential exposure concerns to human health and the environment. Remedial excavation is proposed at site ZZ088 to remove up to 350 cy of lead contaminated soil, as well as encapsulate the former communications building frame with a concrete cap. |

Document, Report, or Work plan Review - other |
DEC approved an updated to Land Use Control (LUC) boundaries for multiple Eielson Sites. Site SO066 and CG505 are NFA sites, where interim LUCs will remain in place until the sites are closed. The LUC Boundary for sites SS079 and SO503 were recommended to be collapsed. It was noted during discussion that the installation of monitoring wells was not included in the Decision Document for site SO503. Air Force has agreed to further review this and propose any changes that may be required for the remedy component of SO503. The LUC Boundary for site SO501 was recommended to be collapsed and shifted to include a previous excavation at the site. Site TU077 requires further investigation and will be presented again at a later date. The proposed LUC boundary for site ZZ088 will be compared to Alaska Department of Natural Resources (DNR) records and presented again at a later date. |
