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

 process flow diagram:

Duck Creek Power Plant consists of a single coal-fired generating unit. Unit 1 is a front-wall-fired Riley Stoker boiler 

and is rated at approximately 4,500 MMBtu/hr heat input. The boiler fires a mix of sub-bituminous and bituminous 

coal.

Unit 1 is equipped with low NOX burners and a selective catalytic reduction (SCR) system to reduce NOX emissions, 

an electrostatic precipitator (ESP) to control particulate emissions and a wet flue gas desulfurization (FGD) system to 

control acid gas and mercury emissions.

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.

O2 and 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:

•	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. 

•	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.
