In December 2003, the EPA promulgated the National Emission Standard for Hazardous Air Pollutants for mercury cell chlor-alkali plants. In February 2004, the Natural Resources Defense Council filed petitions on the final rule in U.S. district court citing, among other issues, the inability of mercury cell industries to fully account for mercury added to their processes to make up for losses via wastes, products and emissions. In April 2004, EPA agreed to reconsider aspects of the rule making which led to planning and execution of emission measurement projects designed to reduce uncertainty in fugitive emissions of Hg from mercury cell chlor-alkali plants. As an overall project goal, the research will use the total site mercury emission data presented in this report, in conjunction with cell room vent monitoring, stack emission and maintenance activity data to determine if the elemental mercury cell room fugitive emissions from the observed facilities are on the order of historical assumptions (1,300 g/day) or on the order of 2002 levels of unaccounted for mercury (approximately 10,000 g/day).
