【 摘 要 】

Many coal-based electric generating units use alternative fuels, and this effort assessed the impact of alternative fuels on CO{sub 2} production and other emissions and also assessed the potential impact of changes in emission regulations under the Clean Air Act (CAA) for facilities utilizing alternative fuels that may be categorized as wastes. Information was assembled from publicly available U.S. Department of Energy Energy Information Administration databases that included alternative fuel use for 2004 and 2005. Alternative fuel types were categorized along with information on usage by coal-based electric, number of facilities utilizing each fuel type, and the heating value of solid, liquid, and gaseous alternative fuels. The sulfur dioxide, nitrogen oxide, and carbon dioxide emissions associated with alternative fuels and primary fuels were also evaluated. Carbon dioxide emissions are also associated with the transport of all fuels. A calculation of carbon dioxide emissions associated with the transport of biomass-based fuels that are typically accessed on a regional basis was made. A review of CAA emission regulations for coal-based electric generating facilities from Section 112 (1) and Section 129 (2) for solid waste incinerators was performed with consideration for a potential regulatory change from Section 112 (1) regulation to Section 129 (2). Increased emission controls would be expected to be required if coal-based electric generating facilities using alternative fuels would be recategorized under CAA Section 129 (2) for solid waste incinerators, and if this change were made, it is anticipated that coal-fired electric generating facilities might reduce the use of alternative fuels. Conclusions included information on the use profile for alternative fuels and the impacts to emissions as well as the impact of potential application of emission regulations for solid waste incinerators to electric generating facilities using alternative fuels.
