Air Permit Number: 6034 Permitted Source ID/Name: Unit 2 MI Permitted Maximum Process Rate: 645 MW Max. Normal Operation Process Rate: 630-645 MW Target Process Test Rate 90-100% of full load

Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The source to be tested is the exhaust from Unit 2 located at the Bell River Power Plant. The air pollution control consists of a Wheelebrator Frye cold gas Electrostatic Precipitator (ESP) that has a design collection efficiency of nominally 99.6%. There is a sulfure trioxide flue gas conditioning system that is only used on an "as needed basis" to lower resistivity of te fly ash for better collection by ESP.

The following describes any modifications and/or deviations to the applicable test methods. If alternative methods were requested, see the attachments for documentation of request AND approval, including dates. Industry/SCC/NAIS221112
