US EPA: Mercury Study Report to Congress - Vol. 8 - An Evaluation of Mercury Control Technology and Costs
EXECUTIVE SUMMARY Section 112(n)(1)(B) of the Clean Air Act (CAA), as amended in 1990, requires the U.S. Environmental Protection Agency (U.S. EPA) to submit a study on atmospheric mercury emissions to Congress. The sources of emissions that must be studied include electric utility steam generating units, municipal waste combustion units and other sources, including area sources. Congress directed that the Mercury Study evaluate many aspects of mercury emissions, including the rate and mass of emissions, health and environmental effects, technologies to control such emissions and the costs of such controls. In response to this mandate, U.S. EPA has prepared an eight-volume Mercury Study Report to Congress. This Report -- Volume VIII of the Mercury Study Report to Congress -- provides information on mercury control technologies, associated costs and regulatory issues. It describes and analyzes additional technologies that could bring about reductions of mercury emissions, and existing state and federal programs that control the use and release of mercury. This Report also describes management alternatives and U.S. EPA's statutory authority to control mercury emissions under section 112 of the CAA.
