Method descriptions are provided below, and quality assurance/qualify control data is provided in Appendix D. Table 3-l: Source Testing Methodology 3.1 U.S. EPA Reference Test Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method l. 'I'o determine the minirnum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to F'igure I - I in U.S. EPA Reference Test Method l. Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type thermocouple and pyrometer. Stack gas velocity pressure and temperature readings were recorded during each test run. The data collected was utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2. 3,2 U.S. EPA Reference Test Method 4 - Moisture Content The stack gas moisture content (BWS) was determined in accordance with U.S. EPA Reference Test Method 4. The gas conditioning train consisted of a series of chilled impingers. Prior to testing, each impinger was filled with a known quantity of water or silica gel. Each impinger was analyzed gravimetrically befbre and after each test run on the sanre balance to deterrnine the anrount of moisture condensed. 3.3 U.S. EPA Reference Test Method 8 - Sulfuric Acid Mist The sulfuric acid mist testing was conducted in accordance with U.S. EPA Reference Test Method 8. The cornplete sanrpling system consisted of a stainless-steel nozzle, heated glass-lined probe, un-heated quartz filter, gas conditioning train, pump and calibrated dry gas meter. The gas conditioning train consisted of one (l) chilled inrpinger containing 100 ml, of 80% isopropyl alcohol (lPA), additional impingers for moisture as needed and a final inrpinger containing 200-300 grams of silica gel. The probe liner heating system was maintained at 120 + l4"C (248 +25'F), and the irnpinger temperaturc was maintained at 20"C (68'F) or less throughout testing. The un- heated quartz filter was used between the outlet of the first irnpinger and the inlet of the second impinger. Following the cornpletion of each test run, the sampling train was leak checked at vacuur.n pressure greater than or equal to the highest vacur-un pressure observed during the run and the contents of the impingers were measured for moisture gain. The contents of the llrst irnpinger were collected in container l.

These rinses and the un-heated filter were added to container l. All samples were sealed, labeled and liquid levels marked for transport to the identified laboratory for analysis. The laboratory used ion chromatography (lC) to analyze the samples in accordance with ALT-133. This is a modification from the current U.S. EPA Reference Test Methodology, which requires titrations. IC is more reliable and accurate than titrations. 3.4 U.S. EPA Alternative Test Method ALT-I53 - Oxygen/Carbon Dioxide The oxygen (Oz) and carbon dioxide (COz) testing was conducted in accordance with U.S. EPA Alternative Test Method ALT-153. One (l) integrated Tedlar bag sample was collected during each test run. The bag samples were analyzed on site with a gas analyzer. The remaining stack gas constituent was assumed to be nitrogen for the stack gas molecular weight determination. The quality control measures are described in Section 3.5. 3.5 Quality Assurance/Quality Control - U.S. EPA Reference Method ALT-I53 Cylinder calibration gases used met EPA Protocol 1 (+l- 2%) standards. Copies of all calibration gas certificates can be found in the Quality Assurance/Quality Control Appendix. Low-Level gas was collected in a Tedlar bag and introduced to the instrument. After adjusting the analyzer to the Low-Level gas concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated for the High-Level gas. For the Calibration Error Test, Low, Mid, and High-Level calibration gases were sequentially collected in a Tedlar bag and introduced to the instrument. All values were within 2.0 percent ofthe Calibration Span. High or Mid-Level gas (whichever was closer to the stack gas concentration) was collected in a Tedlar bag and introduced to the instrument and the time required for the analyzer reading to reach 95 percent or 0.5% (whichever was less restrictive) of the gas concentration was recorded. The analyzer reading was observed until it reached a stable value as defined in ALT-153 Section 4.5, and this value was recorded. Next, Low-Level gas was collected in a Tedlar bag and introduced to the instrument and the time required for the analyzer reading to decrease to a value within 5.0 percent or 0.5% (whichever was less restrictive) was recorded. If the Low-Level gas was zero gas, the response was 0.5%o or 5.0 percent of the upscale gas concentration (whichever was less restrictive). The analyzer reading was observed until it reached a stable value as defined in ALT-153 Section 4.5, and this value was recorded. The initial system bias was determined from this data. The System Bias was within 5.0 percent of the Calibration Span. High or Mid-Level gas (whichever was closer to the stack gas concentration) was collected in a Tedlar bag and introduced to the instrument. After the analyzer response was stable, the value was recorded. Next, Low Level gas was collected in a Tedlar bag and introduced to the instrument, and the analyzer value recorded once it reached a stable response. The System Bias was within 5.0 percent of the Calibration Span or 0.5%o absolute difference or the data was invalidated, and the Calibration Error Test and System Bias were repeated. Drift between pre- and post-run System Bias was within 3 percent of the Calibration Span. If the drift exceeded 3 percent, the Calibration Error Test and System Bias were repeated.
