What should a liquid collection point be used for?

A liquid collection point serves a specific purpose in the context of underground storage tanks (USTs) and vapor recovery systems. It is primarily utilized in situations involving the management of vapors that may be emitted from the tank during the fuel transfer process. When a UST is not buried deep enough to allow for effective vapor recovery, a liquid collection point can help capture these vapors, ensuring they do not escape into the atmosphere. This is crucial for compliance with environmental regulations and safety measures, as uncontrolled vapor release can be harmful to both the environment and public health.

In contrast, storing excess fuel is typically managed by additional storage capacity or external tanks, separating oil from water is a task generally handled by oil-water separators, and improving pressure readings relates to tank monitoring and diagnostics rather than the primary function of a liquid collection point.
