What law requires the use of vapor recovery systems in specific regions?

• A. The Safe Drinking Water Act
• B. The Clean Air Act
• C. The National Environmental Policy Act
• D. The Toxic Substances Control Act

Answer: (B)

The Clean Air Act is the correct answer because it is a federal law that aims to control air pollution on a national level. Under this act, regulations are established to reduce the emissions of harmful pollutants, including volatile organic compounds (VOCs) that can be released during the fueling of vehicles. Vapor recovery systems are specifically designed to capture these vapors, preventing them from entering the atmosphere and contributing to smog and other air quality issues. The act empowers the Environmental Protection Agency (EPA) to set standards and enforce regulations that necessitate the use of such technology in areas identified as having significant air quality concerns, thus promoting public health and environmental protection.
