Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Newton Unit 2 is a tangentially-fired boiler nominally rated at 5,500 million Btu per hour (MMBtu/hr), which entered service in 1982. The boiler supplies steam to a steam turbine with a rated gross electrical generating capacity of 638 MW. The boiler fires pulverized sub-bituminous coals. Unit 2 is equipped with low-NOX burners and an electrostatic precipitator (ESP) to control emissions. An SO3 injection system is used to condition flue gas to improve the efficiency of the ESP. An activated carbon injection (ACI) system is installed upstream of the ESP to control mercury emissions. Industry/SCC/NAIS221112

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.
