Abstract |
The Air Quality Act of 1967 (Public Law 90-148) provided for an intergovernmental system for the prevention and control of air pollution on a regional basis. To put this system into operation, the Department of Health, Education, and Welfare must designate air quality control regions and issue air quality criteria and reports on control techniques. State governments then are expected to establish air quality standards for the air quality control regions and to adopt plans for implementation of the standards. The purpose of this document is to furnish State governments guidance in performing the functions assigned to them under the Act. |
