California ICC UST Inspector Practice Exam

How long must records of cathodic protection system maintenance be kept on file?

1. 10 years

2. 1.5 years

3. 3 years

4. 6.5 years

The correct answer is: 6.5 years

Maintaining records of cathodic protection system maintenance is crucial for ensuring the integrity and safety of underground storage tanks (USTs). The correct duration for keeping these records is 6.5 years. This timeframe is established by regulatory standards that are designed to ensure that any necessary inspections, tests, and maintenance have been adequately documented and are available for review. The 6.5-year requirement aligns with the need for transparency and accountability in the management of UST systems. It provides a sufficient period for reviewing the performance and effectiveness of cathodic protection systems, which are critical in mitigating corrosion and preventing leaks. This duration allows for proper maintenance histories to be established, which can then be referenced during inspections or in the event of a compliance audit. In contrast, shorter record retention periods would not provide adequate historical data for assessing long-term performance or compliance with regulatory requirements. Therefore, retaining records for 6.5 years ensures that both operators and regulators have access to pertinent information regarding the maintenance and functioning of cathodic protection systems.
