What is the typical maximum allowable vapor emissions for gasoline dispensing facilities?

• A. 0.05 to 0.1 pounds of VOCs per thousand gallons
• B. 0.08 to 0.15 pounds of VOCs per thousand gallons
• C. 0.1 to 0.2 pounds of VOCs per thousand gallons
• D. 0.2 to 0.25 pounds of VOCs per thousand gallons

Answer: (B)

The typical maximum allowable vapor emissions for gasoline dispensing facilities is indeed between 0.08 to 0.15 pounds of VOCs (volatile organic compounds) per thousand gallons. This standard is established to minimize the environmental impact of gasoline vapors, which can contribute significantly to air pollution and have adverse health effects.

Regulatory agencies set these limits based on extensive studies that evaluate the potential for emissions and the effectiveness of vapor recovery systems. This particular range reflects a balance between operational efficiency for fueling stations and the need to adhere to environmental protection standards. Facilities must implement vapor recovery technology to capture emissions during the fuel transfer process to comply with these regulatory limits.

Understanding this standard is crucial for ensuring compliance and optimizing the vapor recovery systems in place at gasoline dispensing facilities. Lower or higher limits would either not adequately protect the environment or impose unnecessarily burdensome operational constraints.
