America has been progressively expanding its efforts to control pollution since the first city smoke control ordinances were passed in 1881.
The first major national strides were made in 1970 with the establishment of the Environmental Protection Agency and the 1970 Clean Air Act. The 1990 Clean Air Act Amendments (CAAA) were a landmark effort to reduce air pollution through a variety of instruments including the use of a market-based system of trade-able pollution permits under its Title IV and Title V.
Comprising various staff and office files from the George H. W. Bush presidency, The Clean Air Act Amendments of 1990: Reduction of Acid Rain, Urban Air Pollution, and Environmental Policy supports research in legal, political and environmental disciplines.
The Clean Air Act Amendments Of 1990: Reduction Of Acid Rain, Urban Air Pollution, And Environmental Policy gives researchers access to primary-source memoranda, reports and printed material. Letters include correspondence from organizations such as the Environment Defense Fund, the Clean Air Working Group and the National Association of Manufacturers supporting or opposing specific provisions of the CAAA.
