Description of the source (including control equipment). Please see the attachments for source or

 process flow diagram:

Unit 1 has a rated generating capacity of 84 MW gross and Unit 2 has a rated capacity of 113 MW gross. Each are 

Combustion Engineering tangentially-fired boilers driving steam turbine generator units. Unit 1 burns PRB coal to 

reduce SO2 emissions and is equipped with rotating over-fire air to reduce NOx emissions. Unit 2 burns PRB coal to 

reduce SO2 emissions and is equipped with over-fire air and low NOx burners to reduce NOx emissions. Each unit 

has a dedicated electrostatic precipitator (ESP) to control particulate emissions. Exhaust from each ESP is combined 

and treated by activated carbon injection followed by a fabric filter bag-house and then vented through a common 

stack.
