How long must records of UST system repairs be available on site?

• A. 60 days
• B. 1 year
• C. 5 years
• D. for the remaining lifetime of the UST system

Answer: (D)

Records of UST system repairs must be kept on-site for the remaining lifetime of the UST system. Keeping these records on hand ensures that inspectors and operators can immediately verify exactly what repairs were done, when they were completed, who performed them, and the results of any post-repair tests. This long-term accessibility supports ongoing system integrity, regulatory compliance, and informed maintenance decisions as the system ages or if future issues arise. Shorter retention periods wouldn’t provide a complete historical record for the life of the system, which is why the on-site, lifetime requirement is important.
