What is the required timeframe for conducting a follow-up tightness test after installing cathodic protection?

The requirement for conducting a follow-up tightness test after the installation of cathodic protection is set to ensure the effectiveness of the corrosion prevention efforts. Performing this test within the 3-6 month timeframe allows operators to verify that the cathodic protection system is functioning properly and that there are no potential leaks in the underground storage tank system.

This period is considered optimal because it provides a sufficient window for the cathodic protection system to stabilize and for any immediate impacts of installation to be assessed. Should any issues be detected during this follow-up testing, timely action can be taken to address them, thus minimizing the risk of environmental contamination and ensuring compliance with regulations.
