What are the state requirements for spill containment around a fuel tank?

The state requirements for spill containment around a fuel tank emphasize the importance of having a secondary containment system that can hold at least 110% of the tank's capacity. This is crucial because it ensures that in the event of a leak or spill, the containment system can effectively capture the entire volume of fuel that may escape from the tank, preventing environmental contamination and protecting public health.

Choosing a containment system designed to hold 110% of the tank's capacity speaks to a proactive approach to environmental safeguards. This requirement not only provides ample capacity for leaks but also takes into account potential variations in tank size and operational factors that might impact spill scenarios.

The other options do not meet the comprehensive safety standards required for effective spill containment. For example, simply having a single wall around the tank would not adequately protect against leaks, as it doesn’t provide any additional safety measures. While absorbent materials and periodic testing are useful practices, they cannot replace the need for a robust and reliable containment system capable of holding significant volumes of fuel spills.
