Problems/Comments

Site operated 1957-1972. There are 29 separate sites associated with the main facility not including the White Alice site (Site 31) which is uphill about 1/2 mile. Site 30 is the name given to the various background sampling areas. The Suki River is down gradient of the Drainage Basin (Site 28) area. Contribution to the Suki includes the Headquarters Area and the White Alice Site. The site area is north of the Headquarters Area and generally west of Cargo Beach Road. The area has been impacted from various spills over the years of facility operation, the largest being the ~180,000-gallon spill in 1968 that originated at Site 11. Biota (resident fish and plants) have been impacted by PCBs. A risk assessment was performed on the site in 2003. EPA ID # D981765894. DERP/FUDS. See 475.15.006 for additional information. (rpltr3.1) Last staff assigned were Noland, Ortelee, Markey, Kalu, Rutkowski and Brownlee. A Building Demolition/Debris Removal was completed in 2003. All the buildings, above ground structures and debris were removed from the Headquarters Area and the White Alice site.

Action Information

Action Date	Action	Description	DEC Staff
1/24/2006	Meeting or Teleconference Held	Contaminated Sites staff attended a Restoration Advisory Board meeting in Savoonga for the Formerly Used Defense Site projects on Saint Lawrence Island. The meeting was well attended by RAB members, community members, COE, Technical Assistance Program (TAP) coordinator, Alaska Community Action on Toxins, attorney for the corporation, and DEC. Agenda items included discussion on the biogenic vs petroleum fraction in sediment samples taken during the Phase IV RI. The DEC and COE explained how cleanup levels are determined in sediment and the results of the 2001 Risk Assessment. If the AK 102 levels found in sediment were considered to be 100% petroleum the risk would remain about the same and the response would remain the same. The DEC also explained the how remedial actions are determined through weighing the balancing criteria including toxicity reduction, long term solution, cost, community acceptance, etc	Jeff Brownlee
5/4/2006	Update or Other Action	Contaminated Sites staff reviewed and commented on a 2005 Interim Removal Action Report for the Northeast Cape Formerly Used Defense Site on Saint Lawrence Island. The work completed the Building Demolition/Debris Removal and Containerized Hazardous Waste project from 2003. Work completed included removal and off-island disposal of about 1,500-tons of debris, burning 370-tons of wood, disposing of approximately 290-tons of PCB contaminated soil and 160-tons of PCB impacted concrete	Jeff Brownlee
9/15/2006	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	Jeff Brownlee

1/25/2007	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.

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	Jeff Brownlee

The Corps of Engineers has $23-million programmed to address remaining contamination over the next few years	Jeff Brownlee
11/7/2008	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	Jeff Brownlee
