  • EVALUATION OF STRATEGIES FOR MERCURY MACT COMPLIANCE

    On December 15, 2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The proposed rule ...
