What is one engineering control that can improve vapor recovery effectiveness?

• A. Enlarging storage tanks
• B. Implementing more manual controls
• C. Installing automatic shutoff valves
• D. Reducing system size

Answer: (C)

Installing automatic shutoff valves is an effective engineering control that significantly enhances vapor recovery systems. These valves automatically close at predetermined levels, preventing overfilling of storage tanks and reducing the risk of vapor releases into the atmosphere. By ensuring that the system does not exceed its capacity, automatic shutoff valves help maintain the integrity of the vapor recovery system, thereby maximizing efficiency and minimizing environmental impacts.

In addition to enhancing safety, these valves can also streamline operational processes by reducing the need for manual intervention, making the vapor recovery process more seamless and reliable. Overall, this implementation contributes to better compliance with environmental regulations and can result in cost savings by improving the effectiveness of vapor recovery efforts.
