Spill containment and overfill prevention requirements for underground storage tanks
- OPW Fueling Components, Cincinnati, OH (United States)
Federal Regulations require Underground Storage Tanks (USTs) to be equipped with spill containment and overfill prevention devices by December 22, 1998. Spill containers are designed to contain the product that is often spilled when the delivery hose is disconnected. Spill containers are commercially available in different styles, sizes, and construction materials for various applications. Overfill prevention devices are designed to prevent large releases of product at the fill pipe or through the tank fittings because a tank has been filled beyond its capacity. There are three types of overfill prevention devices. Ball float valves installed on the vapor return line restrict flow into tank when the level in the tank approaches capacity. Overfill alarms provide a warning signal when the level in the tank approaches capacity. Overfill prevention valves shut off flow into the tank when the level approaches capacity.
