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.
