| Abstract: | A methodology has been developed to calculate industrial air pollutant emissions with an absolute minimum of effort. The procedure is dependent upon available industrial fuel data for Standard Industrial Classifications for Standard Metropolitan Statistical Areas as published by the Census of Manufacturers. Emission factors were developed which include both combustion and process losses and six SIC classifications which consume, on the average, about 80 per cent of the industrial fuels in urban areas. In spite of the diversity of industrial processes which dictate the weight of emissions discharged from industrial operation, factors have been developed which are considered representative for urban areas across the nation. The development of such factors permits the calculation of industrial emissions with a minimum of man-hours. The developed procedure allows the calculation of industrial emissions on an urban basis, a state basis, or a nation basis. |
