What are “permeable barriers” used for in UST systems?

Permeable barriers in Underground Storage Tank (UST) systems are specifically designed to contain and manage spills or leakages, which is crucial for environmental protection and safety. These barriers allow for the controlled movement of substances while preventing contaminants from migrating beyond the designated area. By providing this containment, permeable barriers help mitigate the risks associated with potential leaks, thereby safeguarding groundwater and surrounding ecosystems from hazardous materials.

While other features of UST systems serve different purposes—such as enhancing fuel transfer speed or improving ventilation—these functions do not directly relate to managing spills. Monitoring inventory levels is primarily concerned with tracking fuel amounts and ensuring safe operational practices, but it does not involve physical containment of spills. The primary function of permeable barriers focuses on spill management, making it a vital component in maintaining compliance with environmental regulations and ensuring safe operation of UST systems.
