Reviewed "Environmental Condition of Property" (ECP)report. Report presents results of a records review and a site visit by Naval Facilities Engineering Command personnel on June 25 2009, to determine history of site usage, the presence of threatened or endangered species, the presence of natural and cultural resources, environmental conditions, and environmental restoration. The ECP report concludes that the property is suitable for transfer, with recommendations to perform maintenance of landfills as described above, and some general housekeeping consisting of removing small amounts of surface debris. DEC review letter made following additional recommendations:(1) full disclosure if property is transferred; (2) identification of landfill locations on property records; (3) long-term monitoring/maintenance plan for the three landfills; and (4) possible future containment or removal of Landfill A if surface erosion and future coastal erosion threaten a release of landfill contents. |

Meeting or Teleconference Held |
DEC participated in a public meeting in Point Lay with Navy remedial project manager (RPM). Purpose of the meeting was to hear concerns from community members. Point Lay residents voiced concern about impacts to graves located at Icy Cape; potential contamination leaching from landfills to Native allotments; impacts of contaminants on wildlife. Navy RPM informed residents that she is planning a helicopter trip from Barrow to Icy Cape to perform a visual inspection in the next few days. Residents asked if they could travel by boat to meet her at Icy Cape to show specific areas of concern. Navy RPM obtained phone numbers and will plan to call people once date/time of site visit is confirmed. Site visit is currently planned for 8/7/2012. |

DEC approved the final work plan for landfill repairs at the former Icy Cape Distant Early Warning (DEW) Line Station. The scope of work includes inspecting and repairing the landfill caps at Landfills A, B, and C; collecting surface water and sediment samples to determine if contamination is migrating from the landfills; installing survey monuments and conducting a land survey of site features, including the landfill boundaries; and installing land-use restriction signs at each landfill. |

Update or Other Action |
Received request from field regarding the lack of water for sampling and how best to approach it. DEC agreed with the approach to focus sampling where water present, and rely on sediment and/or soil to help delineate the extent of potential overland flow. Recommended opportunistic sampling along the creek in select locations between AW-15 and CW-13. Also consider the collection of other samples (water/sediment/soil) that may be substituted if the new locations will potentially provide information regarding intermittent overland flow of potentially contaminated water. |

Site Characterization Report Approved |
DEC approved the Project Report for 2016 Complementary Studies for Remedial Investigation. The report summarized the background, scope, field activities, results, and conclusions of landfill inspections, surveying and environmental sampling performed in 2016 at the former DEW line station. Soil cleanup levels were exceeded in the landfills for diesel range organics (DRO), residual range organics (RRO), arsenic, and hexavalent chromium. Arsenic, hexavalent chromium, benzene, ethylbenzene, naphthalene, TAqH, DRO, and TAH groundwater concentrations exceeded their respective cleanup levels. Arsenic exceedances in soil and groundwater may be attributable to background soil concentrations. Only total chromium was analyzed, and exceedances of hexavalent chromium in soil and groundwater may not be applicable; speciation of chromium in future sampling is recommended. Additional surface water and groundwater monitoring is recommended, and additional soil sampling may be warranted to delineate the extent of soil contamination downgradient of Landfill A. |
