Description of the source (including control equipment). Please see the attachments for source or process flow diagram:Boiler 5 is a Combustion Engineering boiler originally constructed in 1957. The boiler is equipped with tangentiallyfired low NOX burners to reduce NOX emissions. An ESP with flue gas conditioning is used to control particulate emissions. An activated carbon injection system installed upstream of the ESP is used 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. 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) will be continuously collected at a constant rate from a slipstream of the exhaust of the sample trains into a flexible vinyl bag (IGS bag) per M-3B specifications. A calibrated paramagnetic/IR analyzer will be used in place of a traditional Orsat analyzer to measure drift-corrected O2 and CO2 concentrations of the IGS bags per M-3A specifications. Multiple IGS bags may be collected during lengthy sample runs to ensure sample train integrity; if so, an average O2 and CO2 result for the test run will be calculated. Documentation of preliminary instrument calibrations and post-analysis calibration checks will be included in the appendices of the final report.
