(08/29/03) The mercury cell chlor-alkali plant rule will reduce mercury air emissions by at least 1,500 pounds per year from facilities that produce chlorine and caustic compounds that are used to neutralize acids. There are only nine of these facilities remaining in operation. This rule also requires rigorous work practice standards such as periodically washing work floors and covering waste containers. These additional requirements will reduce mercury emissions from so-called “fugitive sources” throughout the plants. For more information, go to: .
