What does UST stand for in environmental compliance?

The term "UST" stands for Underground Storage Tank. This definition is significant in environmental compliance because USTs are used to store hazardous substances or petroleum products that are located beneath the surface of the ground. The management and monitoring of USTs are critical components of environmental protection efforts, as improper handling or leaks from these tanks can lead to soil and groundwater contamination, posing risks to public health and the environment.

Regulatory frameworks, such as the Resource Conservation and Recovery Act (RCRA) in the United States, set specific standards for the operation, monitoring, and closure of USTs to ensure that potential releases are detected and mitigated in a timely manner. This emphasizes the importance of compliance training and knowledge surrounding USTs for anyone involved in environmental safety and compliance roles.
