Interim Removal Action report (January 2011): approximately 400 cubic yards of contaminated soil were removed, a soil amendment designed to improve degradation was applied and soil sampling was conducted at three areas. At the main excavation area, soil removal was limited by a fence and buried utilities. Benzene- and DRO-contaminated soils remain and groundwater monitoring is recommended. At SB-23, soil samples from the base and sidewalls of the excavation were below cleanup levels. At SB-29, DRO-contaminated soil was identified at the base and sidewalls of the excavation. Additional soil sampling is recommended. This interim removal was completed before this site was transferred to CS. |

Site Visit |
A spill of approximately 150 gallons JP-8 was reported on 12 May 2011. The spill occurred on the south side on the building in the same location as the 2008 and 2009 spills. An estimated 10-30 gallons of free product were recovered immediately adjacent to the building. Approximately 30 cubic yards of contaminated soil were removed on 12 May and taken to the already-existing Building 1211 stockpile. Excavation continued on 13 May but was limited in many areas by buried utility lines. PID readings of up to 1120 ppm were recorded adjacent to the building (where no further excavation can take place). CS declined approval to add a soil amendment (MicroBlaze) to the excavation. PERP and/or CS staff visited the site on both 12 May and 13 May. |

Site Visit |
CS and PERP staff visited the spill site and stockpiles. Approximately 48 cubic yards of contaminated soil have been stockpiled. There are also two drums of soil from the excavation. This stockpile, as well as the stockpile from the 2010 interim removal action, will be transported to OIT when funding is available. Stained soil is still visible at the spill site and additional excavation will occur this week. The excavation will be backfilled with clean soil when no additional soil can practicably be excavated. |

Document, Report, or Work plan Review - other |
Contaminated Sites staff approved a work plan to perform additional delineation at this site. Three soil borings will be taken just outside the SB-29 excavation area, where, during the 2010 interim removal, soil samples from the walls of the excavation area had DRO concentrations above cleanup levels. In addition, one groundwater monitoring well will be installed downgradient of SB-29 and two monitoring wells will be installed downgradient of the main excavation area, where soil removal has been limited by concrete and buried utilities. Monitoring wells will be sampled biannually for the next two years. Stockpiled soil from the 2010 interim removal will be characterized for disposal. |

Document, Report, or Work plan Review - other |
Field Change Form for Installation-Wide Monitoring Program for Eielson Air Force Base. For for missing or damaged wells. Submitted October 1st, 2012 by Eielson to ADEC and EPA. Form states: the following monitoring wells have been identified in the field as either missing or damaged to the extent that it is no longer suitable for sampling: St13/DP26, DP44, SS61, DP25.
Proposed changes as stated on the form: At source areas ST13/DP26, DP44, and SS61, existing mintoring wells are beign sampled under the IWMP, therefore no new suitable wells are available. At source area DP25, a different monitoring well will bes ampled as an alternative to the original well.
Figures are attached with missing/damaged wells marked. |

Update or Other Action |
Staff reviewed the Draft Source Evaluation Report for Multiple Sites at Eielson AFB, of which Bldg 1211 is a part. In a letter dated March 4th, 2013, ADEC noted that the report does not meet the requirements of a Release Investigation, nor complete a full Site Characterization under State regulations. The letter also notes that completed sampling has thus far been limited, and that there are still data gaps to be addressed. Specific to Bldg 1211, the sampling done thus far finds levels of DRO in the soil to be below cleanup levels. |

DEC approved the 2017 Tanker Row Eielson Air Force Base, Alaska Groundwater Monitoring Report, dated June 21, 2018. The document describes 2017 groundwater sampling activities at the Eielson Air Force Base, Defense Logistics Agency (DLA) Tanker Row Building 1211 (Source Area SS534) and Tank 5 (Source Area SS535). During the 2017 sampling event, only seven of the ten wells were sampled for the following analysis; gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), benzene, toluene, ethylbenzene, xylenes (BTEX) and total lead. Polycyclic aromatic hydrocarbons (PAHs) were only collected from one well (SS535-MW05). The only analyte to exceed DEC cleanup levels during the 2017 groundwater sampling was total lead. Benzene was detected, but below the cleanup level. Samples were not collected from the following wells: 1211-MW05, 1211-MW06 (SS534) and SS535-MW01 because they could not be located under the snow piles. The next round of sampling is planned for September/October 2018. |
