Description:
This report describes a study of air pollutants released during the manufacture of chlorinated hydrocarbons. The potential environmental effect of the source was evaluated using source severity, S, defined as the ratio of the maximum ground level concentration of an emission to the ambient air quality standard for criteria pollutants or to a modified TLV (Threshold Limit Value) for noncriteria pollutants. Chlorinated hydrocarbons are manufactured in the U.S. by one of four processes. A representative plant was defined for each manufacturing process type, and the environmental effects were determined on the basis of capacity instead of production. Pollution control technology within the chlorinated hydrocarbon industry consists primarily of control of hydrocarbons emitted from the main process vent, product fractionating vent, storage tanks, fugitive sources, and waste disposal. Assuming that the same level of control will exist in 1980 as existed in 1975, air emissions from the industry are expected to increase by 20% over that period.
