Portions of the facility are subject to provisions of the Utah Department of Environmental quality, Division of Air Quality (UDAQ) Approval Order (AOP) DAQE-AN100080048-21-20; Title V Permit No.300002004; and the Utah State Implementation Plan (SIP) Sections X.H.ll and 12. Testing was conducted to determine the emission rate of niftogen oxides (NOx) at the exhaust of Reheat Fumace #l (R-F#l). 1.1 Source and Control System Descriptions The Reheat Furnace #2 is used to heat the steel billets prior to hot rolling them into marketable shapes. The fumace is equipped with natural gas fired boilers. 1.2 Project Team Personnel involved in this project are identified in the following table.

To determine the minimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure l -2 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 temperafure. 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 3A - Oxygen/Carbon Dioxide The oxygen (Oz) and carbon dioxide (CO2) testing was conducted in accordance with U.S. EPA Reference Test Method 3A. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas conditioning system was a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6. 3.3 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 before and after each test run on the same balance to determine the amount of moisture condensed. 3.4 U.S. EPA Reference Test Method 7E - Nitrogen Oxides The nitrogen oxides (NOx) testing was conducted in accordance with U.S. EPA Reference Test Method 7E. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe, Nucor - Plymouth, UT l0 of 5l AST-2024-3 I 36-007 Page 3-l pill6rrpE) II rtllt.JtCn I Gn()|t)Source Test Reporl Testing Methodologt Teflon sample line(s), gas conditioning system and the identihed gas analyzer. The gas conditioning system was a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6. 3.5 U.S. EPA Reference Test Method 205 - Gas Dilution System Certification A calibration gas dilution system field check was conducted in accordance with U.S. EPA Reference Method 205. Multiple dilution rates and total gas flow rates were utilized to force the dilution system to perform two dilutions on each mass flow confioller. The diluted calibration gases were sent directly to the analyzer, and the analyzer response recorded in an elecfionic field data sheet. The analyzer response agreed within 2o/o of the actual diluted gas concentration. A second Protocol I calibration gas, with a cylinder concentration within l0% of one of the gas divider settings described above, was infioduced directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the analyzer response agreed vvithirr 2Yo. These steps were repeated three (3) times. Copies of the Method 205 data can be found in the Quality Assurance/Quality Control Appendix. 3.6 Quality Assurance/Quality Control - U.S. EPA Reference Test Methods 34 and 7E Cylinder calibration gases used met EPA Protocol | (+l- 2%) standards. Copies of all calibration gas certificates can be found in the Quality Asswance/Quality Control Appendix. Low Level gas was introduced directly to the analyzer. 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 introduced directly to the analyzer. All values were within 2.0 percent of the Calibration Span or 0.5 ppmv lo/o absolute difference. High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe and the time required for the analyzer reading to reach 95 percent or 0.5 ppmv/% (whichever was less restrictive) of the gas concentration was recorded. The analyzer reading was observed until it reached a stable value, and this value was recorded. Next, Low-Level gas was introduced at the probe and the time required for the analyzer reading to decrease to a value within 5.0 percent or 0.5 ppmv/% (whichever was less restrictive) was recorded. If the Low- Level gas was zero gas, the response was 0.5 ppmvlYo or 5.0 percent of the upscale gas concentration (whichever was less reskictive). The analyzer reading was observed until it reached a stable value, and this value was recorded. The measurement system response time and initial system bias were determined from these data. The System Bias was within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference. High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe. After the analyzer response was stable, the value was recorded. Next, Low-Level gas was introduced at the probe, 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 ppmv/%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 or 0.5 ppmvl%o absolute difference. If the drift exceeded 3 percent or 0.5 ppmv/%, the Calibration Error Test and System Bias were repeated.

The pollutant concentrations were measured at three points (16.7, 50.0 and 83.3 percent of the measurement line). Each haverse point was sampled for a minimum of twice the system response time. The pollutant concentration at each kaverse point did not differ more than 5 percent or 0.5 ppmv/0.3% (whichever was less restrictive) of the average pollutant concentration, therefore, single point sampling was conducted during the test runs. Copies of stratification check data can be found in the Quality Assurance/Quality Control Appendix. An NOz - NO converter check was performed on the analyzer at the completion of testing. An approximately 50 ppm nitrogen dioxide cylinder gas was introduced directly to the NOx analyzer and the instrument response was recorded in an electronic data sheet. The instrument response was within +/- l0 percent of the cylinder concentration. A Data Acquisition System with battery backup was used to record the instrument response in one (l) minute averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the completion of testing, the data was also saved to the Alliance server. All data was reviewed by the Field Team Leader before leaving the facility. Once arriving at Alliance's office, all written and electronic data was relinquished to the report coordinator and then a final review was performed by the Project Manager.
