What does the term “release” refer to in the context of USTs?

The term “release” in the context of Underground Storage Tanks (USTs) specifically refers to any escaping or leaking of regulated substances. This definition encompasses a wide range of incidents, including leaks from the tank itself or from associated piping and equipment. It is critical to understand this definition, as releases have serious environmental implications, potentially contaminating soil and groundwater and posing public health risks.

Monitoring for releases is a fundamental aspect of UST management, ensuring the integrity of storage systems and compliance with environmental regulations. Being aware of potential release scenarios and the necessary response actions is essential for operators and is a key responsibility in maintaining the safe operation of USTs. Understanding how to identify and address releases is crucial for minimizing environmental impact and meeting regulatory requirements.
