Problems/Comments

Station was in operation from September 1957 - April 1979. Hazardous materials/wastes known to exist: diesel fuel, lead-acid and nickel-cadmium batteries, asbestos, and electrical equipment contained polychlorinated biphenyls (PCB). This facility is known as the Temporary Auto Storage and Shop, is located directly east of the main road entering Upper Camp. The building has collapsed in recent years and currently the debris from the walls and roof lay aprtially off the concrete slab foundation. As-built drawings indicate the presence of an AST situated at the northeast corner of the building. The 1998 Remedial Investigation reported that the the total volume of contaminated soil is estimated to be 115 cubic yards. No groundwater was encountered during drilling. Depth to bedrock ranges from 3 - 5 feet bgs. A follow-on RI is anticipated for 2003 field season; this study will fill in the data gaps and provide recommendations on potential remedial actions. RCRA EPA ID#AK2570090108. Hazardous waste activity: generator 1. CERCLA AK8570028623 Site encompasses 451 acres in size. In 1968, 1 year after the "AK. Communications Disposal Act", the site along with other WACS was taken over by RCA Alaska Communications (now ALASCOM).
