What type of oil tanks must be liquid tight?

The requirement for all fuel oil supply tanks to be liquid-tight is crucial for environmental protection and safety. Liquid-tight tanks prevent leaks and spills, which can lead to soil and groundwater contamination and pose risks to public health. This regulation ensures that both indoor and outdoor tanks maintain their structural integrity under various conditions, reducing the likelihood of hazardous incidents.

All types of fuel oil supply tanks, regardless of their location or intended use, must adhere to this standard. This includes residential tanks, commercial tanks, and outdoor tanks. By mandating that all supply tanks be liquid-tight, the regulation provides a comprehensive approach to preventing oil spills, thereby ensuring the safety of both the environment and the community.
