What is a common component of spill control in UST systems?

Dual-walled tanks
Single-walled tanks
Non-removable filters
Gravity-based delivery systems

The correct answer is: Dual-walled tanks

A common component of spill control in Underground Storage Tank (UST) systems is the use of dual-walled tanks. These tanks are designed with an inner and outer wall, providing an additional layer of protection against leaks and spills. The space between the two walls can serve as a monitoring area, enabling operators to detect any leaks that may occur in the inner tank. This design significantly reduces the risk of environmental contamination by containing any potential spills that might escape the inner tank, thus enhancing the safety and integrity of the overall storage system. While single-walled tanks and other options may serve specific functions within UST systems, they do not provide the same level of spill containment and monitoring capabilities as dual-walled tanks. Single-walled tanks are more vulnerable to leaks, while non-removable filters and gravity-based delivery systems do not contribute directly to spill control in the same protective manner as dual-walled tanks do. This makes dual-walled tanks a critical component for spill prevention and management in UST systems.
