What is the primary purpose of an Underground Storage Tank (UST) system?

The primary purpose of an Underground Storage Tank (UST) system is to store petroleum products or hazardous substances below ground. These tanks are designed specifically for the secure containment of these materials, minimizing the risk of leaks or spills that could harm the environment or public health. By being situated underground, USTs offer important advantages, such as reduced exposure to weather elements and physical damage, as well as compliance with regulations aimed at protecting the soil and groundwater from contamination.

Understanding the nature of the substances stored is crucial, as petroleum products and hazardous substances have specific handling and storage requirements. This specialized focus on environmental safety is what distinguishes USTs from other storage solutions.
