Document, Report, or Work plan Review - other |
DEC received Badger Elementary School Facility ID #3498 8,000-Gallon Diesel Underground Storage Tank Site Assessment/Tank Closure Report dated Nov 2010, prepared by ICA.
The tank system was removed and recycled "as is" for future use. Approximately 245 cy of diesel contaminated soil and approximately 233 gallons of diseil contaminated water were removed and tranported to OIT for thermal remediation. Approximately 2-4 cy of contaminated soil (2,260 mg/kg) remains in the excavation, 3 to 5 feet bgs; soil could not be removed without jeopardizing the transformer. A shallow groundwater monitoring well (MW-1) was installed adjacent to the new tank. Clean (below ADEC cleanup levels) stockpiled soil may remain on site. (MBarnes) |
