Problems/Comments
Vertical AST tanks were replaced with horizontal ones. 12" of gravel, the old liner, and 2' of soil below the liner to permafrost were removed. 3 Samples described as "composite" collected at permafrost had detectable GRO below Method 1 Arctic soil cleanup levels; DRO was at 178, 243 and 387 mg/kg. Excavation was backfllled with clean soil, then layers of insulation, geotextile, a liner and 12" of clean gravel before the tanks were installed. Excavated material was placed on a liner on site until lab results were available. Approximately 300yd contaminated soil/gravel was then moved from gas station tank farm to a larger tank farm at the Petro Star Refinery and placed on a liner.
