Risk Assessment Report Approved |
ADEC received the Final Risk Evaluation Report – Alaska North Slope Radar Installation Sites on November 6, 2007. This report meets the requirements of the ADEC Contaminated Sites Program Risk Assessment Procedures Manual, adopted by reference in 18 AAC 75.340. An approval letter was sent to Dave Cook, Program Manager HQ PACAF/A7NR, on December 10, 2007 This project identified categories of sites that are common on remote Air Force installations in the North Slope region of Alaska and developed conceptual site models and human health and ecological risk based screening levels for four of these categories: garage sites, fuel storage sites, non-fuel storage sites, and transformer sites. The project developed templates for conducting human health and ecological risk evaluations for these categories and performed a risk evaluation as a test case for one example of each type of site. The final report contains guidance on applying the process to other North Slope region sites. It may be used on a site-specific basis as a tool to assist in assessing potential risks posed by North Slope Air Force installation sites.

Meeting or Teleconference Held |
ADEC staff attended a Restoration Advisory Board meeting in Wainwright, Alaska. The purpose of the meeting was to update the community with the results of the 2007 Investigation Report. The attendees at the meeting included the Air Force, their consultant, ADEC, the Bureau of Land Management (BLM), and a couple of members from the community. There is a lot of interest in the former Dew Line site because the Oil Companies are interested in using the airstrip and pad for logistical support for the off-shore drilling operations planned in the area. The Air Force plans to conduct Clean Sweep of the site during FY2010. The primary contaminants of concern at the various sites are petroleum and Polychlorinated Biphenyls (PCBs). The old landfill (LF006) is located outside of the Air Force boundary and is currently eroding into the lagoon. PCBs were identified at one area in the landfill at levels above 1 parts per million. The cleanup levels established for the site are the proposed Method 2 Arctic Zone levels for areas not located near surface water bodies and Method 1 Arctic Zone levels for areas that are located next to surface water or have the potential for eroding into surface water bodies. BLM was against the Air Force creating a new landfill at the site for the disposal of any debris or soil during the Clean Sweep Program. Future discussions will be necessary to address these issues when the cleanup plans are submitted for the Dew Line site. |

Document, Report, or Work plan Review - other |
DEC staff reviewed and approved the Final Landfill 006/Landfill 005 Interim Removal Action work plan, dated February 2010. Landfill site LF006 is eroding into the Wainwright Lagoon. The interim removal actions associated with this site include excavating and sampling the landfill, segregating and containerizing solid waste and contaminated soil, and transporting solid waste and contaminated soil for proper treatment or disposal. This work will be done in March and April to allow site access over the frozen tundra. An on-site laboratory will be established to aid decision making in the field. Asbestos containing material has been identified at LF005. The actions associated with LF005 include removing the asbestos containing material and digging test pits to further characterize the landfill. |

CERCLA ROD Approved |
DEC signed three Record of Decisions describing the final selected remedies for the Old Landfill Site (LF006), the Garage Area (SS007), and the Module Train Area (SS004). The selected remedy for LF006 includes excavating buried material and contaminated soil from LF006 and shipping it off-site for disposal. The Air Force performed the excavation and disposal of LF006 in March/April of 2010 as an interim removal action to prevent additional erosion of the landfill contents into the lagoon. The contaminants of concern at the Garage Area (SS007), which includes the Garage Building, the Base Supplies and Equipment Building, and the POL Hut, are PCBs, diesel range organics, and residual range organics. The selected remedy includes removing the PCB and/or petroleum contaminated soil and properly treating or disposing of it off-site. The contaminants of concern at the Module Train Area (SS004) are PCBs and diesel and residual range organics. The selected remedy includes excavating the PCB and/or petroleum contaminated soil and properly disposing of it off-site. |

Interim removal actions at the old landfill included excavating and sampling the landfill, segregating and containerizing solid waste and contaminated soil, and transporting solid waste and contaminated soil for proper treatment or disposal. Approximately 4,350 cubic yards of soil and debris contaminated with petroleum, oil, and lubricants and PCBs were removed. Excavation activities also removed 330 cubic yards of inert metal debris and 38 drums of solid waste. The interim removal actions at the new landfill included removing the asbestos containing material and digging test pits to further characterize the landfill. |

Document, Report, or Work plan Review - other |
Approved the final Remedial Action Report for the Module Train Area, the Garage Area, the Old Landfill, and the Former Minimally Attended Radar Station (MARS) pipeline. At the Module Train Area PCB and petroleum contaminated soil was removed and transported offsite for treatment. Evidence of a previously undocumented petroleum release under the Module Train Area was encountered during excavation, and additional remedial action will be needed to remove the remaining petroleum contamination. At the Garage Area PCB and petroleum contaminated soil was removed and transported offsite for disposal. Confirmation sampling results indicate that remaining contaminant concentrations are all below the cleanup levels. At the Old Landfill site, 20 sediment samples were collected from within the Kuk Lagoon, offshore from where the interim removal action was performed in 2010. The samples were analyzed for PCBs and results were all below the cleanup level. At the Former MARS Pipeline site, pipelines that connected two former 40,000-gallon diesel skid mounted tanks to the MARS buildings were removed. There were no indications of leaks or spills during removal actions, and confirmation sample results were all below the cleanup levels. |

Document, Report, or Work plan Review - other |
Approved the final landspread report documenting the treatment of petroleum-contaminated soil from the former Beach Diesel Tank site at the Wainwright SRRS. Contaminated soil was transported from the Beach Diesel Tank site to the main SRRS installation in May 2010 for treatment. The gravel was spread on the runway to a maximum depth of 6 inches. This report presents the results of surface water sampling and multi-increment (MI) sampling of the landspread material and the former stockpile locations. All results are below the cleanup levels. The landspread material on the runway was graded, leveled, and compacted to make it suitable for fixed wing aircraft use. |
