The law was initially enacted as the Air Pollution Control Act of 1955. Amendments in 1967 and 1970 (the framework for today's U.S. Clean Air Act) imposed national air quality requirements, and placed administrative responsibility with the newly created Environmental Protection Agency. Major amendments followed in 1977 and 1990.
[9] The Clean Air Act requires periodic review of NAAQS, and new scientific data published after 1977 made it necessary to revise the standards previously established in the 1977 Lead AQCD document. An Addendum to the document was published in 1986 and then again as a Supplement to the 1986 AQCD/Addendum in 1990.
In 2008—by which point a total of fourteen states had joined the suit—the U.S. Court of Appeals for the District of Columbia ruled that the EPA regulations violated the Clean Air Act.
