Who is responsible for conducting the tightness testing of a temporarily closed UST?

The responsibility for conducting the tightness testing of a temporarily closed underground storage tank (UST) rests with a certified UST supervisor. This individual is trained and qualified to perform the necessary procedures to ensure that the tank is secure and not leaking, which is critical for environmental protection and compliance with state regulations. Tightness testing checks the integrity of the UST system and helps to prevent potential groundwater contamination.

Having a certified UST supervisor conduct this testing ensures that the procedures follow industry standards and regulatory requirements. Their expertise allows them to interpret testing results accurately and to address any issues that may arise. This not only safeguards the environment but also protects the owner from potential liabilities associated with leaks or failures of the UST system.
