### 2.3 Presentation of Results A single sampling train was utilized during eaeh run at each location to determine the mass emission rate of SO z at the P002 Exhaust Stack and at the P008 Exhaust Stack during normal maximum achievable operations. These sampling trains measured the stack gas volumetric flow rate, dry molecular weight, moisture content, and concentration of SO z . Table 2.2.1 displays the mass emission rate of S02 measured at the P002 Exhaust Stack and at the P008 Exhaust Stack during normal maximum achievable operations. Note that the mass emission rates of S0 2 measared at the P002 Exhaust Stack and at the P008 Exhaust Stack were both well below the Title V permitted liinit of 129.7 Ib/hr. A single sampling train was utilized during eaeh run to determine the mass em'rssion rate of total filterable PM at the P901 Baghouse Exhaust Stack during normal maximum achievable operations. These sampling trains measured the stack gas volumetric flow rate, dry molecular weight, moisture content, and concentration of total filterable PM. Table 2.2.2 displays the mass emission rate of total filterable PM at the P901 Baghouse Exhaust Stack during normal maximum achievable operations. Note that the mass emission rate of total filterable PM measured at the P901 Baghouse Exhaust Stack was well below the Title V permitted limit of 4.06 ]b/hr. The tota) filterable PM concentration values in Table 2.2.2 denoted with a'<' were measured to be below the minimum detection limit (MDL) of the applicable analytical method. Total filterable PM mass emission rates denoted with a'<' in Table 2.2.2 were calculated utilizing the applicable MDL concentration values instead of the "as measured" concentration values. The accepted MDL for EPA Method 5 is 0.0020 grains/dscf for a 32 dscf sample.

## 4.0 SAMPLING AND ANALYTICAL PROCEDURES 4.9 Test Methods 4.1.1 EPA Method l: Sample and Velocity Traverses for Stationary Source Principle: Principle: To aid in the representative measurement of pollutant emissions and/or total volumetric flow rate from a stationary source, a measurement site where the effluent stream is flowing in a known direction is selected, and the cross-section of the stack is divided into a number of equal areas. A traverse point is then located within each of these equal areas. This method was utilized in its entirety as per the procedures outlined in 40 CFR Part 60, Appendix A. 4.1.2 EPA Method 2: Determination of Stack Gas Velocity and Volumetric Flow Rate (type S Pitot Tube) Principle: The average gas velocity in a stack is determined from the gas density and from measurement of the average velocity head with a Type S(Stausseheibe or reverse type) pitot tube. This inethod was utilized in its entirety as per the procedures outlined in 40 CFR Part 60, Appendix A. 4.1.3 EPA Method 3: Gas Analysis for the Determination of Dry Molecular Weight Principle: A gas sample is extracted from a stack by one ofthe following methods: (1) sing1e-point, grab sampling; (2) single-point, integrated sampling; or (3) multi-point, integrated sampling. The gas sample is analyzed for percent CO2, percent 0 2 , and if necessary, for percent CO. For dry molecular weight determination, either an Orsat or a Fyrite analyzer inay be used for the analysis. This method was utilized in its entirety as per the procedures outlined in 40 CFR Part 60, Appendix A. 4.1.4 EPA Method 4: Determination of Moisture Content in Stack Gases Prine' rple: A gas sample is extracted at a constant rate from the source; moisture is removed from the sample stream and determined either volumetrically or gravimetrically. This method was utilized in its entirety as per the procedures outlined in 40 CFR Part 60, Appendix A. 4.1.5 EPA Metihod 5: Determination of Particulate Emissions from Stationary Sources (Filterable PM only) Principle: Particulate matter (PM) is withdrawn isokinetically from the source and collected on a glass fiber filter maintained at a ternperature in the range of 120 ± 14 ° C (248 t 25 ° F) or such other temperature as specified by an applicable subpart of the standards or approved by the Administrator, U.S. Environmental Protection Ageney, for a particular application. The PM mass, which ineludes any material that condenses at or above the filtration temperature, is determined gravimetrieally after removal of uncombined water, This inethod was utilized in its ertirety as per the procedures outlined in 40 CFR Part 60, Appendix A. 4.1.6 EPA Method 6: Determination of Sulfur Dioxide Emissions from Stationary Sources Principle: A gas sample is extracted from the sainpling point in the stack. The sulfuric acid mist (including sulfur trioxide) and the sulfur dioxide (SO z ) are separated. The S02 fraction is measured by the bariuwnthorin titration method. This method was utilized in its entirety as per the procedures outlined in 40 CFR Part 60, Appendix A. The sampling trains utilized during this testing project are depicted in Figures 4.1 and 4.2.
