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

Ameren UE owns and operates the Sioux Power Plant, located in West Alton, Missouri.

Unit 2 is a Babcock and Wilcox cyclone-fired boiler installed in 1968 and rated at

approximately 524 MWe gross and 4,920 million Btu per hour (MMBtu/hr) heat input.

The boiler fires a mix of sub-bituminous and bituminous coals.

The Unit 2 boiler utilizes an over-fire air system to control NOX emissions. Unit 2 is

equipped with a cold side electrostatic precipitator (ESP) with flue gas conditioning to

control particulate emissions.

The testing described in this document was performed at the Unit 2 Stack.

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.

Oxygen (O2) and carbon dioxide (CO2) data (units of dry volume percent, %dv) used in

molecular weight calculations, O2 correction and calculation of Fd-based emissions

(units of lb/MMBtu) were obtained in the following manner during the test program:

• For non-instrumental (wet) sampling methods, a modified version of EPA

Method 3B was utilized.

o Multi-point, integrated gas samples (IGS) were continuously collected at a

constant rate from a slipstream of the exhaust of the sample trains into a

flexible vinyl bag (IGS bag), per Method 3B specifications.

o A calibrated paramagnetic/IR analyzer was used in place of a traditional

Orsat analyzer to measure drift-corrected O2 and CO2 concentrations of the

IGS bags, per Method 3A specifications.

o Multiple IGS bags were collected during lengthy sample runs to ensure

sample train integrity. Average O2 and CO2 results for each test run were

calculated.
