(09/05/03) EPA divided the chlorine production industrial source category into two subcategories to better account for differences in production methods and toxic emissions. The subcategories are: mercury cell chlor-alkali plants and chlorine production plants that do not rely upon mercury cells for chlorine production. Mercury cell chlor-alkali facilities emit mercury and mercury compounds into the air and are regulated by an air toxic regulation targeting those emissions. EPA is deleting from its list for control the subcategory of sources that do not utilize mercury cells to produce chlorine and caustic. EPA has determined that air emissions of these compounds from industrial facilities that produce chlorine are already below protective levels and provide an ample safety margin.
