The Clean Air Act
November 15, 1990. President George Bush signs the Clean Air Act Amendments, deemed to be the most significant environmental legislation ever passed. The Amendments seek ways to reduce smog and atmospheric pollution, which includes prohibiting the use of leaded gasoline in motor vehicles by the end of 1995.
