Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Elm Road Generating Station (ERGS) consists of two 615 MW supercritical pulverized coal (SCPC) boilers, which fire Eastern bituminous coal. Each unit is equipped with five air pollution control systems: Fabric Filter Baghouse, FGD System, Selective Catalytic Reduction (SCR) system, Low NOx burners, and Wet Electrostatic Precipitator (WESP). Unit 1 commenced initial commercial generation in October 2009. Industry/SCC/NAIS221112
