Stage I vapor recovery prevents vapors from escaping into the environment by doing what?

Stage I vapor recovery systems are designed to capture and recycle vapors during the process of product delivery to underground storage tanks. When a fuel truck delivers gasoline to a storage tank, vapors that are created in the tank as fuel is displaced need to be managed to prevent them from escaping into the atmosphere.

As the gasoline enters the tank, the vapors in the tank displace and move up through the delivery hose into the fuel truck. The vapor recovery system captures these vapors and routes them back into the delivery vehicle rather than allowing them to escape into the environment. This not only helps to reduce air pollution and greenhouse gas emissions but also enhances safety by preventing flammable vapors from accumulating in the air.

By recycling the vapors directly back into the tank truck during delivery, Stage I vapor recovery effectively reduces the release of harmful vapors into the atmosphere, thereby meeting environmental regulations designed to protect air quality. The focus is on maintaining controlled conditions during the transfer of fuel and minimizing any potential negative environmental impacts associated with fuel dispensing operations.
