Retrospective Study - 1970 to 1990
On October 15, 1997, EPA issued the first in this series of reports, entitled "The Benefits and Costs of the Clean Air Act, 1970 to 1990," following completion of a six-year process of study development and outside expert review. The report shows that the public health protection and environmental benefits of the Clean Air Act exceeded the costs of its programs by a large margin.
