In the context of UST operations, what does secondary containment help to prevent?

Secondary containment plays a crucial role in UST operations by serving as an additional layer of protection that helps to prevent environmental contamination from leaks. Essentially, it refers to structures or systems designed to contain any leaks or spills from the primary storage tank or piping. This containment helps to ensure that any hazardous substances that might escape from the primary containment are confined within a controlled area, preventing them from reaching the surrounding soil, groundwater, or surface water.

This is particularly important because leaks from underground storage tanks can lead to significant environmental harm, contamination of drinking water sources, health risks for nearby communities, and substantial cleanup expenses. By implementing secondary containment measures, operators can mitigate these risks effectively and comply with regulatory requirements designed to protect the environment.

Other potential concerns related to operational delays or costs might be valid considerations within the broader context of UST management, but they do not directly relate to the primary benefit of secondary containment, which is specifically aimed at safeguarding the environment.
