What is the minimum duration a Class A operator must maintain UST site inspection records?

A Class A operator is responsible for overseeing the operation of underground storage tanks (USTs), ensuring they comply with regulatory requirements, and maintaining accurate records of site inspections. The correct duration for maintaining UST site inspection records is a critical aspect of compliance with environmental regulations. The requirement to keep such records for at least three years allows for adequate documentation and accountability in case of inspections or audits by regulatory authorities. This timeframe provides sufficient historical data to monitor trends, detect potential issues, and ensure that the UST systems are operating safely and in adherence to environmental protections. By keeping these records for three years, operators can also address any unforeseen incidents or discrepancies that may arise during that period.
