What is the maximum allowed vapor loss from a Stage I vapor recovery system during delivery?

The maximum allowed vapor loss from a Stage I vapor recovery system during delivery is established based on environmental regulations and technical standards designed to minimize air pollution and control volatile organic compounds (VOCs) released during fuel transfers. In this context, 0.95 pounds per 1,000 gallons is the acceptable threshold, which means that for every 1,000 gallons of fuel delivered, a maximum of 0.95 pounds of vapor can be lost to the atmosphere.

This regulation is crucial for ensuring that vapor recovery systems are functioning effectively and that businesses comply with environmental standards to protect air quality. Adhering to this limit helps to mitigate the impact of emissions from gasoline vapors, which can contribute to smog and health issues in communities surrounding fuel delivery sites.

A vapor recovery system should be maintained and monitored regularly to ensure it operates within these limits, as exceeding the specified amount may indicate a failure in the system or improper installation. Understanding these values is essential for environmental compliance and operational efficiency in the fuel delivery industry.
