This report responds to a September 14, 2004, request from Chairmen James M. Inhofe and George V. Voinovich asking the Energy Information Administration (EIA) to analyze the impacts of different approaches for removing mercury from coal-fired power plants. The senators asked that EIA analyze the impact of alternative mercury control strategies, including the Environmental Protection Agency's (EPA) proposed cap and trade system (EPA-Cap), EPA's proposed mercury maximum achievable control technology (EPA-MACT), and a 90-percent mercury MACT approach. Chairmen Inhofe and Voinovich also requested that EIA assume that EPA's proposed Clean Air Interstate Rule (pCAIR) is in force and that only commercially demonstrated mercury removal technologies can be used.
