"IOC™" Integrated Overflow Compartment: Modern's IOC tank was created to eliminate spills, environmental cleanup and monetary loss related to overfilling aboveground storage tanks. Modern's special overfill prevention design directs the excess product into the "Integrated Overfill Compartment". This only happens when the product level in the tank exceeds the 95% capacity rating. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction.

Quality counts.
