The Clean Air Act - Highlights of the 1990 Amendments
On November 15, 1990 the Clean Air Act was revised with overwhelming bipartisan support and signed into law by President George H. W. Bush. Specifically the amendments were designed to curb four major threats to the environment and to the health of millions of Americans: acid rain, urban air pollution, toxic air emissions, and stratospheric ozone depletion. The amendments also established a national operating permits program to make the law more workable, and strengthened enforcement to help ensure better compliance with the Act.
The amendments featured several progressive and creative new approaches for effectively achieving the air quality goals and regulatory reform expected from these far-reaching amendments.
