An above ground storage container assembly comprises a steel tank for volatile liquid housed within a concrete vault. The walls of the vault are spaced from the tank to provide an air envelop around the tank. The air envelop is vented to prevent the tank from rusting or corroding. Lifting bars are anchored in the vault so that the entire assembly may be raised. A spill trap surrounds the fill opening from the tank and also surrounds a drain hole with removable plug.
