What does 'Decommissioning' entail for an underground storage tank?

Decommissioning an underground storage tank involves taking the necessary steps to safely remove the tank from use, ensuring that it does not pose a risk to the environment or public health. This process typically includes pumping out any remaining fuel, properly disposing of any residues, and conducting soil sampling to assess the presence of leaks or contamination around the tank. Adhering to established standards during this phase is crucial, as it guarantees that all potential hazards are addressed and mitigated effectively.

In contrast, continuous monitoring of the tank's condition pertains more to active tanks still in use rather than those being decommissioned. Replacing the tank with a larger one or repairing it for future use does not pertain to decommissioning; these actions imply that the tank is still in service or intended to be used again, rather than fully removing it from service and addressing any potential environmental impacts from its previous operation.
