Cathodic protection systems are essential for preventing corrosion in underground storage tanks and piping systems by providing a protective electrical current. After installation, it is crucial to conduct an inspection to ensure the system is functioning correctly and providing adequate protection against corrosion.

The requirement for inspection within six months of installation is grounded in industry standards and regulatory guidelines. This timeframe allows for a prompt evaluation of the system's effectiveness and any necessary adjustments or repairs to be identified and implemented early on. Timely inspections are critical for maintaining compliance and ensuring the integrity of the system, ultimately protecting the environment and public safety.

While other timeframes, such as three, twelve, or eighteen months, may involve routine maintenance or follow-up inspections, they do not meet the immediate need for a certified tester to verify the operational status of newly installed cathodic protection systems. Therefore, six months is the specified period required for this initial inspection following installation.
