How frequently should UST systems with cathodic protection be inspected?

UST systems equipped with cathodic protection should be inspected every three years to ensure that the protection remains effective in preventing corrosion of the storage tanks and associated piping. This regular inspection is crucial because cathodic protection systems can deteriorate over time due to various factors, including environmental conditions and system wear and tear. By following the three-year inspection interval, operators can identify and rectify any issues with the cathodic protection system, thus maintaining the integrity of the UST and reducing the risk of leaks that could lead to environmental contamination and regulatory violations. Consistent monitoring ensures compliance with regulations and extends the lifespan of the storage system.
