The Clean Air Act, first enacted in 1963 and amended several times in later years, is a federal law designed to protect and improve air quality in the United States. The Act has been instrumental in reducing air pollution, promoting public health, and safeguarding the environment.
The Clean Air Act regulates six major pollutants: carbon monoxide, lead, nitrogen oxides, ozone, particulate matter, and sulfur dioxide. It sets standards for emissions from sources such as power plants, factories, and vehicles and establishes requirements for monitoring and reporting of air quality.
