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 for the Formerly Used Defense Sites (FUDS) on Saint Lawrence Island. Participants at the meeting included Alaska Community Action on Toxins (ACAT), the RAB Technical Assistance Program representative, the COE Alaska District, the native corporation attorney, RAB members and DEC. Agenda items included discussion of the remedial actions that took place in Gambell during the summer season included a summary of the Native American Lands Environmental Mitigation Program (NALEMP) work. The Gambell NALEMP project is the largest in the nation with 290,000 pounds of buried debris removed in 2006. There was discussion on the groundwater sampling event at Site 5 which is several monitoring wells surrounding the village water supply well. There were detected levels of DRO and metals (lead, nickel, barium) in a couple wells, but well below the cleanup levels. We also discussed the Feasibility Study for Northeast Cape and the upcoming final of that document |

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 |

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. |
