This report describes the results of a survey of the secondary zinc smelting and refining industry to determine the probable impact of the development of new source performance standards under Section 111 of the Clean Air Act. This industry recovers zinc as metallic zinc, zinc dust, zinc oxide, or zinc alloys from scrap by melting or distillation processes. However, primary zinc smelters and refiners, who process zinc from ore, were excluded, even though they also process scrap to recover zinc. Information was gathered by collecting process, emission, and economic data from literature searches; contacting air pollution control agencies, other government agencies, industry representatives, and trade associations; and visiting a secondary zinc plant. The report describes the industry, projects production and capacity to 1989, and describes industry processes, actual and allowable air emissions, and emission control systems. State and local emission regulations are compared and the probable impact of a new source performance standard is assessed.
