What equipment may be included in underground storage systems?

Vapor-recovery piping and equipment are essential components in underground storage systems, particularly in systems designed for storing fuels. Their primary function is to capture and recover potentially harmful vapors that are emitted during the filling and dispensing of fuel. This not only helps in minimizing emissions, which is critical for environmental protection, but also prevents the loss of valuable fuel that might otherwise escape into the atmosphere.

The inclusion of vapor-recovery systems is mandated by various regulations to ensure compliance with air quality standards. By capturing vapors that can contribute to smog and other environmental issues, these systems play a crucial role in safeguarding public health and the environment. Moreover, effective vapor recovery enhances operational efficiency, as it reduces the amount of product lost during operations.

Other equipment, such as pumping and filtering systems, heating systems, or compressors and regulators, may be part of certain installations but are not as universally standard in underground storage systems as vapor-recovery equipment. Their functions might support the overall operation but do not address the specific needs related to vapor emissions and environmental compliance that make vapor-recovery systems particularly significant within this context.
