ABSTRACT:
An underground storage tank system has an internal retained capacity area for receiving excess liquid from a filling operation. The storage tank system comprises a rigid storage tank, a fill pipe, a vapor recovery tube, a vent line, a dispensing line, and a trapped vapor release valve. A vapor recovery extension tube and vent extension line each extend into the storage tank. The uppermost of the lower end of the vapor recovery extension tube and lower end of the vent extension line within the storage tank defines a horizontal plane above which is an internal retained capacity area. The trapped vapor release valve is closed during a filling operation so that eventually a build up of pressure occurs within the retained capacity area to prevent further flow of liquid to the retained capacity area of the tank. Opening of the trapped vapor release valve relieves the pressure in the retained capacity area thereby allowing excess liquid in the fill pipe and delivery hose to drain into the storage tank.
