What is the primary function of a vapor recovery system in USTs?

• A. To enhance water pressure
• B. To capture vapors released during product dispensing
• C. To store additional fuel
• D. To cool down the stored products

Answer: (B)

The primary function of a vapor recovery system in underground storage tanks (USTs) is to capture vapors released during product dispensing. This system plays a critical role in preventing air pollution and reducing the risk of fire and explosion hazards associated with flammable vapors. When fuel is dispensed from the tank, it creates a vacuum that can draw vapor into the atmosphere. A vapor recovery system captures these vapors instead of allowing them to escape, effectively reducing emissions and allowing them to either be returned to the tank or processed further. This not only helps in maintaining environmental compliance but also improves the overall efficiency of fuel systems by recapturing valuable product.
