How long can out-of-service commercial fuel tanks remain underground before removal?

1. 30 days

2. 180 days

3. 365 days

4. 730 days

The correct answer is: 365 days

The correct duration for how long out-of-service commercial fuel tanks can remain underground before they must be removed is one year, or 365 days. This timeframe is established to ensure safety and environmental protection. Fuel that remains in tanks can pose significant hazards, including leaks that may contaminate soil and groundwater, as well as fire risks. The 365-day limit helps enforce a proactive approach to tank management, prompting property owners to either remove or properly assess the tanks for potential risks within a reasonable period. Other choices reflect shorter or longer timeframes that may not meet regulatory requirements or best practices for safety concerning abandoned or inoperative fuel tanks. Adhering to the one-year limit minimizes risks associated with aging tanks and promotes accountability in managing fuel storage systems.
