Clean Air Act

1963 CE - 1970 CEU.S.A.

The Clean Air Act of 1963 was enacted to substitute the Air Pollution Control Act of 1955, designed to control air pollution on a national level and becoming the country's most influential modern environmental laws, and one of the most comprehensive air quality laws worldwide. Major amendments followed in 1970, 1977, and 1990 to expand federal government activities. In 1970, the EPA was created to implement the various requirements included in the Clean Air Act.
