Is release protection required during temporary tank closure?

During temporary tank closure, release protection is not required. This means that if a storage tank is temporarily closed and not actively dispensing or storing regulated materials, the stringent measures typically needed to prevent leaks and releases into the environment are not mandated at this stage.

Temporary closure generally implies that the tank system has been emptied and cleaned, reducing the risk of leakage significantly compared to an operational tank. While best practices may still encourage certain precautions to prevent any possible releases, regulatory requirements for release protection measures specifically apply to active use situations where hazardous materials could be present. As a result, the absence of an active threat creates a regulatory environment where release protection during temporary closure is not mandated.

It's essential to consider the implications of each option. While hazardous materials might require more careful handling, the rules surrounding temporary closure themselves do not escalate the need for release protection. This understanding is critical for those involved in the handling and regulation of underground storage tanks to ensure compliance with state standards and to assess the safety of tank operations effectively.
