Which situation requires an underground storage tank to be tested every two years?

1. If it has a capacity of 550 gallons or larger

2. If it is located in a rural area

3. If it has a capacity of 1,100 gallons or larger

4. If it is used for hazardous materials

The correct answer is: If it has a capacity of 1,100 gallons or larger

An underground storage tank must be tested every two years if it has a capacity of 1,100 gallons or larger because regulations aimed at preventing leaks and protecting the environment are particularly stringent for larger tanks. Tanks of this size pose a greater risk of contamination if they were to leak, which can lead to severe environmental hazards. Therefore, regular testing is mandated to ensure that these tanks are structurally sound and not leaking hazardous substances into the surrounding soil and groundwater. This practice aligns with the regulatory focus on larger storage capacities, as they are typically associated with commercial or industrial operations that potentially handle more dangerous materials. Ensuring that these tanks are compliant with safety and environmental standards is essential for preventing environmental damage, safeguarding public health, and maintaining compliance with state and federal regulations.
