Which federal act governs the regulations concerning the ozone layer protection?

The Clean Air Act is the federal legislation that addresses air quality and establishes regulations aimed at protecting the ozone layer. Specifically, it includes provisions that regulate substances known to deplete the ozone layer, such as chlorofluorocarbons (CFCs) and halons. The Act was amended in 1990 to include stricter controls to phase out the production and consumption of these ozone-depleting substances, which is critical for global efforts to reduce harm to the ozone layer.

While the National Environmental Policy Act focuses on environmental impact assessments for federal projects and the Safe Drinking Water Act pertains to the regulation of public drinking water supplies, these statutes do not specifically target ozone layer protection. The Resource Conservation and Recovery Act is primarily concerned with solid and hazardous waste management, which also does not relate directly to the issues surrounding ozone depletion. Therefore, the Clean Air Act stands out as the appropriate choice for governing regulations aimed at protecting the ozone layer.
