Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Hatfield’s Ferry Power Station operates 3 coal-fired boilers (Units 031, 032, and 033) which generate electricity for sale and distribution. Each unit consists of a 570 megawatt (MW) Westinghouse generator driven by a 5,766 million British thermal units per hour (MMBtu/hr) Babcock & Wilcox boiler retrofitted with low NOx cell burners. Each unit is also equipped with an electrostatic precipitator and a flue gas desulfurization system. The units exhaust to individual stacks contained within a concrete annul.
