UTILITY CONTROLS COULD TRANSFER MERCURY TO DRY WALL MAKERS

EPA officials may consider first-time mercury emissions regulations for wallboard manufacturers because the industry production techniques could release mercury trapped in power plant waste as a result of utility controls required by the agency's controversial new mercury rule. Utility researchers, wallboard manufacturers and Energy Department (DOE) officials are launching a series of new studies to quantify how much mercury from utility waste is released when the waste is processed and heated during the manufacture of wallboard. However, it is unclear...
