Which agency is responsible for overseeing vapor recovery systems in the United States?

• A. Occupational Safety and Health Administration (OSHA)
• B. Environmental Protection Agency (EPA)
• C. Department of Transportation (DOT)
• D. Federal Aviation Administration (FAA)

Answer: (B)

The Environmental Protection Agency (EPA) is the agency responsible for overseeing vapor recovery systems in the United States. This responsibility falls under the EPA's broader mission to protect human health and the environment by enforcing regulations related to air quality and pollution control. Vapor recovery systems are crucial for reducing emissions from fueling operations and containing gasoline vapors, which can be harmful to both the environment and public health.

The EPA sets standards and guidelines for vapor recovery systems as part of its efforts to minimize air pollution, especially in areas that are nonattainment for air quality standards. By regulating these systems, the EPA ensures that the technology used in fueling stations and storage tanks prevents the release of harmful vapors during the filling and dispensing processes.

Other agencies, such as OSHA, focus on worker safety and health, while the DOT regulates transportation and infrastructure. The FAA handles aviation matters, which do not directly pertain to vapor recovery for fuel storage and dispensing. Therefore, the EPA's role is pivotal in managing vapor recovery systems effectively to mitigate environmental impact.
