What is the Clean Air Act of 1970?

The Clean Air Act of 1970 is a landmark piece of federal legislation aimed at regulating air emissions from stationary and mobile sources. This law authorizes the Environmental Protection Agency (EPA) to establish and enforce national standards for various air pollutants to protect public health and the environment. It focuses on improving air quality by setting limits on harmful emissions, which helps reduce air pollution, protect the ozone layer, and combat climate change.

The act encompasses numerous amendments and expansions over the years, enabling the EPA to monitor air quality, develop state implementation plans, and enforce compliance with pollution standards. By establishing a comprehensive regulatory framework, the Clean Air Act plays a crucial role in safeguarding air quality and public health across the United States.

The other options, while related to environmental regulation, do not accurately describe the focus of the Clean Air Act. For instance, the law does not address water quality, land use, or waste management directly, which are specific to other regulations and statutes.
