How many months between inspections for vapor recovery units?

• A. 3 months
• B. 6 months
• C. 12 months
• D. 24 months

Answer: (B)

Vapor recovery units are inspected on a six-month schedule. This semiannual interval keeps emissions controls reliable and regulatory-compliant by catching wear or malfunctions—like worn seals, corroded fittings, stuck valves, or faulty sensors—before they lead to leaks during transfers. During the inspection, technicians typically check the physical condition, test the system’s pressure or vacuum operation, verify valves and connections, and review maintenance records to ensure timely service. The other intervals—three months, annually, or every two years—don’t align with the practical need to detect developing issues promptly or to avoid unnecessary testing frequency.
