Underground Storage Tank Decommissioning

Marysville, WA

This project consisted of decommissioning a 12,000 gallon underground storage tank and associated refueling facilities including to product dispensers were also decommissioned and removed.

The tanks were decommissioned by removal according to the national standards of practice.  Fluid wastes were removed, and the tanks were taken to a landfill facility for proper disposal. 

Ground water was present in the tank excavation at three feet below ground surface.  A reconnaissance groundwater sample collected from the excavation showed to be clear of any fuel particulates.
