Throgmorton, James A. 1979. Technical Assistance in Developing Nonattainment Plans for Selected Areas in California EPA 909/9-79-003. Research Triangle Park, NC: U.S. Environmental Protection Agency.
This is a report I wrote for the California Air Resources Board (CARB) while working as a consultant for PEDCo Environmental Inc. back in 1979. It was intended to assist the CARB by defining the nature, extent, and causes of violations of standards governing total suspended particulates in the air basins of the north coast, Sacramento Valley, San Joaquin Valley, and south central coast of the State and to identify the potential means of eliminating these violations.
