Meeting or Teleconference Held |
Staff attended a meeting with Air Force and EPA personnel to resolve comments on the draft Eielson Five-Year Review. Issues with the document included event-driven groundwater sampling at several contaminated sites, which we denied pending further clarification of the process, and closing numerous sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), but keeping them open under the State until 18 AAC 75 diesel range organic cleanup levels are met. |

Meeting or Teleconference Held |
ADEC met with Eielson AFB and contractor to review the Draft Site Characterization report for the CITS sites. QA/QC issues were discussed and there is a need for further data validation before the report can be approved. DRO and GRO are contaminants of conern and above ADEC cleanup levels. DRO is present in the ground water and exceeds ADEC cleanup levels. |
Emily Youcha |
| 6/21/2005 |
Site Characterization Report Approved |
Data from 2002 indicates an area of DRO- and GRO-contaminated soils exists above ADEC Method Two cleanup levels. Ground-water sampling results indicate DRO-contaminated water exceeds ADEC Groundwater cleanup levels at MW-1.4. ADEC does not consider this effort a complete characterization as required by 18 AAC 75.335 because the cleanup levels and techniques were not proposed in the report. Additionally, the report did not evaluate the potential threat to human health, safety, and the environment from the contamination. This step is often evaluated in a conceptual site model (CSM) and in calculations of risk. Since this information was not included in the characterization report, ADEC would expect this type of information in a future proposed cleanup plan for this site. |

Update or Other Action |
ADEC agreed to decrease sampling of the North Boundary Wells from annual sampling to biennial. Upcoming measurements will be summer 2007, 2009, 2011, etc. Concentrations of VOCs, SVOCs, and metals in the sentinel wells have been monitored annually since 1992 and there has been no detection of contamination. |

Update or Other Action |
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. |

Exposure Tracking Model Ranking |
A new updated ranking with ETM has been completed for source area 74663 Bldg 3426 Supply Facility. Restrictions are currently in place to prevent contaminant exposures. Approval is required for any activity on site that can result in access or movement of groundwater or soil. The installation or use of drinking water wells is restricted, and all monitoring wells are secured with locks to prevent unauthorized access to groundwater. Additionally, a 200-foot buffer boundary is on the site until better delineation can be defined. |

Document, Report, or Work plan Review - other |
DEC provided comments to the USAF on the draft "2014 Site Characterization Report, Various Sites, Eielson Air Force Base, Alaska dated June 2015 (the 2014 CRP SCR). The 2014 CRP SCR describes sampling activities completed at PL001(M), CS082, SS530, SS068, SS083, TU531, CS074, CG517, SS533, TU077, SS519, SS079, CS525 at Eielson Air Force Base in July, August and September of 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. |

Site Characterization Report Approved |
DEC reviewed and approved the Site Characterization Report for Source Areas SS068, SS083, CS525, TU077, SO501, CG527, SS079, SS519 Eielson Air Force Base, Alaska, Final, dated November 2018. The report describes results of site characterizations (SCs) at multiple contaminated sites
managed under the Compliance Restoration Program (CRP) at Eielson Air Force Base (AFB),
Alaska. In order to delineate the extent of contamination at the eight CRP sites included in this report, Environmental Compliance Consultants, Inc. (ECC) partnered with Jacobs Engineering Group Inc. (Jacobs) to collect surface and subsurface soil, groundwater, surface water, and sub and near-slab soil gas samples; conduct an analytical data quality review; and screen for human health risk. Analytical sampling conducted during the 2015 through 2017 field activities closed data gaps from previous investigations and demonstrated that further characterization is not needed at three of the CRP sites; the remaining six sites require further investigation. |

Long Term Monitoring Workplan or Report Review |
DEC received and approved a Revised (Revision 1) Final Supplemental Site Characterization Report for Sites SS068 SS083 SS519 CS525 CG527, Eielson Air Force Base, Alaska, dated January 2023. Revision 1 incorporates corrected analytical reports that were provided by the laboratory in December 2022, after the approval of the Final Supplemental Site Characterization Report. The corrected analytical reports include three non-detect results for 1,4-dichlorobenzene in soil at site CS525 that were previously reported erroneously as detections. The changes do not affect the conclusions of the report. |
