Abstract |
The Clean Air Act, as amended, directs the Secretary of Health, Education, and Welfare to designate 'air quality control regions' to provide a basis for the adoption of regional air quality standards and the implementation of those standards. The Act stipulates that the designation of a region shall be preceded by consultation with appropriate State and local authorities. This report is intended to provide the basic background information needed for the consultation. It proposes boundaries for the Four Corners Interstate Air Quality Control Region and discusses the factors which are the basis of the proposed boundaries. |
