Overview
On November 15, 1990, Congress enacted the Clean Air Act Amendments. The amendments made sweeping changes to the way air quality is regulated in the United States. The legislation was designed to curb three major threats to human health and the environment: acid rain, urban air pollution, and toxic air emissions.
