Update or Other Action |
Contaminated Sites staff reviewed and commented on a draft Feasibility Study for the Northeast Cape Formerly Used Defense Site on Saint Lawrence Island. No further action is proposed for 17 out of 30 sites at the facility. The study presents several remedial alternatives for the remaining sites including containment such as capping, insitu such as chemical oxidation and ex-situ treatments such as incineration or excavation and off site disposal. Limited actions such as natural attenuation, long-tem monitoring and institutional controls are also evaluated. The study does not attempt to choose specific alternatives, but evaluates the balancing criteria including cost for each individual site. Remedial alternatives will be chosen during development of the Proposed Plan. It is probable that many of the sites will have chosen remedies that are a combination of the presented alternatives for example excavation and off-site disposal combined with institutional controls and long-term monitoring |

Meeting or Teleconference Held |
Contaminated Sites staff participated in a Restoration Advisory Board meeting for the Formerly Used Defense Sites on Saint Lawrence Island, Alaska. The meeting was held in Savoonga and attended by members of the RAB and community, Corps of Engineers, the COE contractor, Alaska Community Action on Toxins, the attorney for the native corporation, and the Technical Assistance Program advisor for the RAB. Agenda items included a discussion of the geophysics results of the investigation at the Site 7 Landfill, Responsiveness Summary for the Northeast Cape Proposed Plan and the changes to the plan that are resulting from those comments |

Update or Other Action |
Contaminated Sites staff reviewed a draft Decision Document for the Northeast Cape Formerly Used Defense Site (FUDS) on Saint Lawrence Island. There are several sites at the former surveillance station and White Alice Site to be remediated. The Headquarters Area has extensive diesel range organics impacting soil and groundwater. An insitu chemical oxidation pilot test will be done at a portion of this area to assess effectiveness for treating the larger contaminant mass. The drainage and wetlands below the Headquarters Area is planned for dredging or excavation of the more highly impacted sediments. There are several sites that will be excavated for petroleum and Polychlorinated Biphenyl (PCB) soil contamination. There will be institutional controls on several areas including two landfills, areas with residual petroleum impacts and shallow groundwater use controls |

Meeting or Teleconference Held |
Contaminated Sites staff participated in a Restoration Advisory Board (RAB) meeting for the Northeast Cape Formerly Used Defense Site (FUDS). The meeting was held in Savoonga on Saint Lawrence Island and attended by the Corps of Engineers, the Technical Assistance Program representative, Alaska Community Action on Toxins, the Island Corporations attorney, RAB members, and interested community members. Discussion items included the Northeast Cape Decision Document which is in draft final review, remedial activities planned for this summer including Site 7 landfill investigation and capping and the Headquarters area chemical oxidation pilot study. We also discussed the ongoing Gambell NALEMP project and a new NALEMP project being started for the Fish Camp at Northeast Cape to remove possible lead based paint and asbestos in cabins built in the area from abandoned facility materials |

Update or Other Action |
General information and activity at this site was previously entered as associated directly with the FUDS. However, in July 2011, a new ADEC database site was created to adequately reflect the status of this site as a NALEMP project that is being addressed and funded separately from FUDS. That site is now ADEC file number 475.38.023 and is named Northeast Cape Fish Camp NALEMP. Site is a Native American Lands Environmental Mitigation Program (NALEMP) which is associated and adjacent to the formerly used defense site (FUDS) Northeast Cape; for which the Army Corps of Engineers is the lead federal agency and responsible party. The NALEMP provides federal funding to conduct remediation and mitigation for the purposes of addressing environmental concerns that are not eligible to be addressed under the FUDS program. Environmental concerns at the site consist mainly of contaminated building materials (including asbestos and lead-based paint) that were historically provided to the Native Alaskan residents at the Northeast Cape site by the U.S. military. The site also contains miscellaneous containerized petroleum products and several small locations of observed soil staining. Previous site characterization and removal actions have been conducted in 2009, 2010, and 2011 that have included characterization and abatement of materials containing lead-based paint and asbestos. Further site characterization and removal action efforts are planned for the 2012 season. |

Meeting or Teleconference Held |
CS staff participated in the semiannual Restoration Advisory Board (RAB) meeting which was conducted in Savoonga, AK on Saint Lawrence Island. Participants included representatives from the Army Corps of Engineers, ADEC, Savoonga residents and RAB members, the Alaska Community Action on Toxics, and the University of Alaska, Anchorage (UAA). The agenda included presentations by the Army Corps which summarized the 2014 and 2015 remedial efforts and results. The Army Corps conducted the last major removal and offsite disposal actions in 2014 and conducted groundwater monitoring at the Main Operations Complex in 2015; the 2015 draft report is pending. Dr. Frank von Hippel of UAA presented a summary of the results from a multi-year fish tissue sampling and analysis study to evaluate PCBs in Nine-spine Stickleback and AK Blackfish in the Suqi River; the drainage of which flows through the Northeast Cape FUDS. |

CERCLA Removal Action Report |
ADEC received the Final 2014 Northeast Cape Removal Action Report (which is dated May 2016), and submitted final approval of the report to the Army Corps of Engineers. Site characterization and removal action requirements that are outlined in the 2009 Decision Document were conducted in consecutive years since 2009 and were completed in 2014. Future and ongoing work planned within the current five-year review period (2014-2018) includes monitoring as well as follow-on sampling and analyses of surface waters, sediments, groundwater, and soils; including the development and implementation of land use controls, and notices of environmental contamination with the landowner. |
