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 (RAB) meeting, public meeting and tribal meeting to introduce the proposed plan for the Northeast Cape FUDS. The meetings were held in Gambell and Savoonga and were well attended with high interest from the community. Alaska Community Action on Toxins (ACAT), the Technical Assistance Program (TAP) coordinator, corporation attorney, and Corps of Engineers were represented at the meeting. The proposed plan outlines the preferred remedies for the 34 sites at the facility |

Site Characterization Report Approved |
Contaminated Sites staff reviewed a geophysical prove out report for an investigation of two sites at the Northeast Cape Formerly Used Defense Site. Site 7 is an unpermitted landfill that has a topographic high point that was in question of being a natural feature or buried debris. The investigation indicates the feature is natural and that debris was side cast off the point. Site 7 and Site 10 both have known buried drums containing fluid and the investigation was designed to target anomalies for future intrusive investigation to determine if any other fluid filled drums remain buried |

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 |
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. |
