How often should UST systems with cathodic protection be inspected for proper operation?

UST systems equipped with cathodic protection should be inspected for proper operation at least annually. This frequency is primarily to ensure that the cathodic protection system effectively mitigates corrosion and maintains the integrity of the underground storage tanks. Regular inspection helps identify issues early, allowing for timely maintenance or repairs, which is crucial in preventing environmental contamination and ensuring compliance with regulatory requirements.

Conducting inspections yearly aligns with best practices for maintenance and safety in the petroleum storage industry. It ensures that any degradation or malfunction of the cathodic system can be addressed before it leads to significant problems, such as leaks or failures. Consistent and frequent checks are essential in managing risks associated with UST systems, thus safeguarding both the environment and public health.
