What is a "release" in the context of USTs?

In the context of Underground Storage Tanks (USTs), a "release" refers specifically to any spilling or leaking of hazardous materials from the tank. This critical definition encompasses a range of scenarios where hazardous substances, such as fuel or chemicals stored within the UST, escape into the environment. Understanding this term is vital for compliance with environmental regulations, as releases can pose significant risks to soil and groundwater contamination, jeopardizing public health and safety.

Monitoring and managing releases is a key aspect of UST operation and maintenance, as it enables facilities to address issues promptly and mitigate environmental damage. Recognizing a release as a hazardous event underscores the importance of rigorous monitoring, regular inspections, and prompt reporting to regulatory bodies when such incidents occur.
