What is one regulatory requirement for aboveground fuel storage tanks?

Aboveground fuel storage tanks are subject to several regulatory requirements to ensure safety and environmental protection. One major requirement is that they must be equipped with spill prevention measures. This is crucial as fuel can pose significant environmental hazards if spilled, potentially contaminating soil and water supplies. Implementing spill prevention measures, such as containment systems or secondary containment areas, helps mitigate the risks associated with leaks or spills, which is a key aspect of regulatory compliance in managing fuel storage.

The other options presented do not align with established regulatory standards. For instance, while certain aesthetic regulations may exist, the requirement to paint tanks a specific color is not a universal regulation. Furthermore, fuel storage tanks can hold various types of fuel, including gasoline and kerosene, not just diesel fuel. The positioning of the tanks relative to buildings does have safety considerations but is usually governed by specific local codes rather than a blanket requirement of being at least 100 feet away.
