Problems/Comments
In 2013 and 2014, the City of Tanana placed approximately 2,800 cubic yards of contaminated soil from the former Tanana Power Company contaminated site (Hazard ID 3946, file no. 780.38.014) at a landfarm constructed at the City of Tanana landfill. The material was generated during excavations for two new City of Tanana structures at the former Tanana Power Company contaminated site (closed with institutional controls in 2012). The City of Tanana project was funded under the DEC Brownfield Assessment and Cleanup program. The City of Tanana committed to managing the landfarm. The landfarm has two cells, one larger cell (23,300 square feet) generated in 2013 and another smaller cell (8,000 square feet) generated in 2014. Diesel range organics (DRO) in the larger cell ranged from 1,490 mg/kg to 11,700 mg/kg. The larger cell had benzene concentrations up to 0.0292 mg/kg. In the smaller cell, DRO ranged from 11,800 mg/kg to 22,400 mg/kg and benzene concentrations were detected at up to 0.0257 mg/kg.
