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. o	Documentation of preliminary instrument calibrations and post analysis calibration checks were included in the appendices of the final report. o	For Method 30B, O2 and CO2 data were obtained from an average of all isokinetic test runs performed that day. o	For Method SW-846 0031, O2 and CO2 data were obtained from the simultaneously-performed Method SW-846 0011.•	For instrumental (continuous) test methods, O2 and CO2 data were obtained from a continuous paramagnetic / nondispersive infrared (NDIR) analyzer operated concurrently and in parallel with the other analyzers.
