What does not need to be done when a UST system is permanently closed?

When a UST system is permanently closed, it is essential to understand the required steps to ensure compliance with regulations and safety. Ensuring that all valves are opened is not a necessary action during the closure process. Instead, the closure procedures focus on safely managing the contents of the tank and making sure that the system is rendered secure and environmentally safe.

During the closure of a UST, it is critical to file closure documentation to maintain a record of the closure activities, which serves as proof of compliance with regulatory requirements. Additionally, removing tanks, lines, and pumps is important to eliminate potential hazards and prevent leaks. Furthermore, handling all hazardous materials appropriately is crucial for environmental safety and compliance, ensuring that any risks associated with the stored materials are addressed. Opening all valves does not contribute to these objectives and is not required, as it may even create unnecessary risks during the closure process.
