Which environmental regulation typically governs vapor recovery systems?

Vapor recovery systems are primarily governed by the Clean Air Act, which focuses on the regulation of air quality and the control of air pollution. This Act is designed to protect the air quality in the United States by establishing standards for emissions and enhancing the management of hazardous air pollutants. Vapor recovery systems play a crucial role in controlling volatile organic compounds (VOCs) and other harmful emissions that can contribute to air pollution and smog formation. By capturing vapors that would otherwise escape into the atmosphere during fuel transfer and storage, these systems help in meeting the requirements set forth by the Clean Air Act, thus ensuring compliance with federal air quality standards.

In contrast, the other regulatory options listed focus on different environmental concerns. The Clean Water Act addresses water pollution, the Superfund Act is concerned with the cleanup of hazardous waste sites, and the Resource Conservation and Recovery Act deals with waste management and disposal practices. Therefore, while these laws are vital for environmental protection, they do not specifically govern the operations of vapor recovery systems.
