摘要

EPA's strict air toxics rules for power plants will likely limit depositions of mercury and other pollutants to surface waters, a long-time concern for state officials, but the rule is also likely to prompt more direct releases of the toxics to waters, driving planned changes to strengthen the agency's 1982 effluent limitation guideline (ELG) for the plants. Under the terms of a court settlement with environmentalists, EPA signed the maximum achievable control technology (MACT) emissions standard for coal- and oil-fired power plants late last year, setting strict numeric limits on emissions of mercury, acid gases and metals along with work practice standards for dioxins and furans. The measure is intended to replace a Bush-era rule that was vacated by a federal appellate court.
