The underground storage tank had two gouge marks and 2- and 4-mm corrosion holes along the bottom. There was a sheen on the groundwater. Two soil samples indicate DRPH at 7520 ppm and 12,900 ppm, GRPH at 1160 ppm and 82 ppm, and total BTEX at 79 ppm and 0.1 ppm with no detectable benzene. Tank is adjacent to site ST20 (ADEC file number 107.38.069/Hazard ID 346), which is contaminated with JP. |

Document, Report, or Work plan Review - other |
2014- Draft Multiple Compliance Restoration Program Sites RI Work Plan received March 1, 2014. In 2012, 9 soil and 2 groundwater samples were collected and analyzed for DRO, RRO, GRO, VOC, SVOCs, and metals. To asses if impacted media during UST removal remained, and the extent of contamination present. Results showed DRO present in one well with concentration of 1,660mg/kg (cleanup level 250 mg/kg). Arsenic exceeded Cleanup levels in both soil and groundwater sampling. Additional field work is expected in the 2014 field season. |

On April 23, 2014, the Alaska Department of Environmental Conservation and the United States Air Force reached agreement on the State-Eielson Air Force Base Petroleum Site Restoration Agreement (Two-party Agreement). This agreement was established to perform any necessary assessment, monitoring, remediation and cleanup determinations for petroleum contaminated sites at Eielson Air Force Base. This site was identified as a petroleum contaminated site requiring a response action and its cleanup will continue under Alaska regulations, following the procedures established in the agreement. |

Document, Report, or Work plan Review - other |
DEC provided comments to the USAF on 8/28/15 on the "DRAFT 2014 Site Characterization Report For Sites Where Investigation is Complete: PL001 (A to L), SS066, SO501, SO503, CG505, CG527, MY529, Eielson Air Force Base, Alaska" dated July 2015. This report describes sampling activities completed at seven sites at Eielson Air Force Base in 2014. Sampling of soil and groundwater was conducted to evaluate data gaps from previous investigations; delineate the nature and extent of soil and groundwater contamination; determine the potential for co-mingling of plumes from separate sites; and to determine the need, or lack thereof, for further investigation at each site. |

Update or Other Action |
DEC approved the "Sampling and Analysis Plan, Nose Dock 7 Fire Suppression System, Eielson Air Force Base, Alaska, FTQW 06-2467" dated October 2015 for use. The plan describes sampling that will occur during the construction of a 15' x 15' concrete foundation adjacent to Building 1306. The proposed activities call for excavation to a maximum depth of 4' below ground surface and should not encounter groundwater. |

Update or Other Action |
DEC signed the Decision Document for Installation Restoration Program Source Areas SO066, TU077, SS079, SO501, SO503, and CG505, Eielson AFB. The document identifies selected remedies for petroleum contaminated sites at Eielson Air Force Base, Alaska. The final selected remedy, excavation of affected soil, is proposed to address fuel and VOC contamination in soil at Source Area SO503. The contamination currently presents a potential risk to human health and the environment; however, the proximity of the contaminated soil to Facility 1311, the arctic walkway, and a potential utilidor pathway currently prevents excavation of the contaminated soil. Therefore, LUCs and eventual excavation are recommended for soil at SO503. |

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. |
