The Clean Air Act (CAA or Act) touches virtually every aspect of economic activity in the United States. It requires the U.S. Environmental Protection Agency (EPA) to establish national ambient air quality standards (NAAQS) for certain pollutants to protect public health and welfare nationwide. The Act provides a comprehensive set of regulations to monitor air toxins and requires major sources of air pollution to obtain detailed operating permits. The CAA also requires states to adopt enforceable plans to achieve and maintain air quality standards, and to control harmful emissions that might drift across state lines.

Other key provisions of the CAA are designed to minimize increases in pollution from the growing number of motor vehicles and from new or expanded industrial plants.  The law requires new stationary sources (e.g., power plants and factories) to use the best available technology and allows less stringent standards for existing sources.
