What characterizes a tank that is considered "abandoned"?

A tank is considered "abandoned" when it is unused indefinitely without being emptied or altered. This definition emphasizes that abandonment involves inactivity over a prolonged period, indicating the tank serves no current purpose or function. When a tank is left unused for an extended time, it can also pose risks, such as potential environmental contamination, if it contains residual materials or vapors.

In this context, a tank that has not been emptied or modified is at risk of deterioration, leaks, or becoming a hazard to public health and the environment. Proper protocols need to be in place to address these risks, which makes recognizing an abandoned tank crucial for regulation and safety purposes. This characterization distinguishes an abandoned tank from other statuses, such as intermittent use or decommissioned tanks, which have different definitions and implications for management and regulatory compliance.
