How long must records of protection systems maintenance be retained?

3 years
5 years
6.5 years
10 years

The correct answer is: 6.5 years

Records of protection systems maintenance must be retained for a minimum of 6.5 years. This requirement is in line with regulatory standards that aim to ensure that all necessary documentation related to the maintenance of underground storage tank (UST) systems is available for review and compliance verification. Retaining these records for this duration allows for sufficient oversight and ensures that any maintenance activities can be verified if questions arise regarding the integrity and safety of the protection systems. This timeframe balances the need for accountability with practical limits on record-keeping, making it an industry standard in compliance practices.
