Underground Storage Tank (UST) Designated Operator A Certification Practice Test

The minimum number of most recent records of cathodic protection testing that owners and operators must keep is two. This requirement ensures that operators have a clear and up-to-date history of cathodic protection testing, which is crucial for maintaining the effectiveness of corrosion prevention measures for underground storage tanks. Keeping at least two records allows operators to track any changes or trends in protective measures over time, ensuring that any issues can be identified and rectified promptly. This practice is part of maintaining compliance with regulatory standards that aim to protect the environment and public health from potential hazards associated with UST systems. Proper record-keeping not only aids in demonstrating adherence to regulations during inspections but also supports proactive management of tank integrity.
