Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Fayette Power Project Unit 3 began operation in 1988 and is a nominal 470 MW electric generating facility. It is permitted to burn 100% lignite or coal, and any combination of either fuel. The unit has not burned lignite for more than 10 years, only subbituminous coal. The original design included a cold-side electrostatic precipitator and a wet limestone flue gas desulfurization system. In April 2005, seperated overfire air was added for NOx control to meet annual emission limits established by the Texas Commission on Environmental Quality. Industry/SCC/NAIS 221112
