California UST System Operator Practice Test

Are non-operating cathodic protection systems eligible for repair?

1. Yes

2. No

3. Only if they are over five years old

4. Only if they fail more than twice

The correct answer is: Yes

Non-operating cathodic protection systems are eligible for repair because maintaining the integrity and functionality of these systems is crucial for preventing corrosion in underground storage tanks. Cathodic protection is a vital part of ensuring the long-term safety and regulatory compliance of UST systems; thus, any system, even if currently non-operating, needs to be brought back to operational status to ensure it provides the necessary protection against corrosion. Properly functioning cathodic protection systems help to protect the tank and associated piping from corrosion, which can lead to leaks and environmental hazards. Therefore, when a system is identified as non-operational, it is not only permissible but often necessary to undertake repairs to restore its function. This proactive approach aligns with best practices for environmental safety and tank integrity. In contrast, options suggesting that repairs would depend on the age of the system or the number of failures imposed unnecessary limitations; cathodic protection systems should be repaired regardless of these factors to fulfill regulatory obligations and best practices in environmental protection.
