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. Site 3 (pumphouse and pipeline) is adjacent to Cargo Beach. The 4" welded pipline begins at the beach and parallels the road about 8,000-feet to the Headquarters Area. There were two 500-gallon AST at the pumphouse. Petroleum contamination is present in soil below the pumphouse and in area groundwater. 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 including those at the White Alice site.

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

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
8/10/2010 Site Visit Staff conducted site visits to observe the status of ongoing remediation work being conducted by the Army Corps. of Engineers under the 2010 HTRW Removal Action Work Plan. 2010 remediation efforts included the removal of 1,500 tons of PCB-contaminated soil at sites 13, 21, and 31; the removal of 2,700 tons of petroleum-contaminated soil at Sites 3, 6, and 32, the removal of 17 tons of arsenic-contaminated soil at Site 21; construction of a landfill cap at Site 9; and the removal of 38.5 tons of metal and wood debris from Sites 9, 29, and site wide. Other work conducted included a UVOST investigation to delineate the petroleum-contaminated soil at the main operations complex, ground water monitoring at the main operations complex, and monitoring of natural attenuation of diesel contamination at Site 8 via surface water and sediment sampling.

9/12/2011 Site Visit ADEC conducted multiple site visits and inspections of 2011 remedial work being implemented sitewide. Curtis Dunkin
10/13/2015 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.
