Performance Test Report for Wood Fired Meat Smoker Project number: 89735150 4. Quality Assurance/Quality Control and Data Reporting During the monitoring program, a strict quality assurance/quality control (QA/QC) program adhering to the procedures outlined in the referenced methods identified in previous sections was follawed. Equipment was inspected for proper operation and durability prior to calibration. Calibration of equipment is conducted in accordance with the procedures outlined in the EPA document entitled "Quality Assurance Handbook for Air Pollution Measurement Systems; Volume |||—Stationary Source Specific Methods" (EPA/600/R-94/038c, September 1994). Equipment calibration is performed in accordance with EPA guidelines and/or manufacturer’s recommendations. Documentation of all calibration records are kept in the project file during the field prograrn and are attached in Appendix ¢€ of this test report. The QA/QC aspects of the program are discussed in the following sections below. 4.1 Pitot Tubes [QA Handbook Section 3.1.2, pp. 1-13 - measured for appropriate spacing and dimensions or calibrate in a wind tunnel. Rejection criteria are given on the calibration sheet. Post-test check - inspect for damage.] Each S-type stainless steel Pitot tube used is designed to meet geametric configurations as defined in EPA Method 2. 4.2. Thermocouples [QA Handbook Section 3.4.2, pp. 15-18 - verify against a mercury-in-glass thermometer at two or more points including the anticipated measurement range. Acceptance limits - impinger +2°F; dry gas meter (DGM) +5.4°F; stack +1.5 percent of stack temperature.] The Type K thermacouples in each meter control box, heated sample bax, impinger umbilical connector, resin trap, and sample probe are calibrated against ASTM mercury-in-glass thermometers at two or more points: an ice bath, ambient temperature, and a boiling water bath. 4.3 Dry Gas Meters [QA Handbook Section 3.4.2, pp. 1-12: calibrate against a wet test meter or calibrated orifice. Acceptance criteria - pretest Yi = Y + 0.02; post-test Y = + 0.05 Yi.] Dry gas meters for all sampling trains are calibrated using critical orifices. The procedure entails four runs using four separate critical orifices running at an actual vacuum 1-2 in. greater than the theoretical critical vacuum. The minimum sample volume required per orifice is 5 ft. Meter boxes are

our runs using four separate critical orifices running at an actual vacuum 1-2 in. greater than the theoretical critical vacuum. The minimum sample volume required per orifice is 5 ft. Meter boxes are calibrated annually. 4.4 Field Barometer [QA Handbook Section 3.4.2, pp. 18-19 - compare against a mercury-in-glass barometer or use Airport Station Barometric Pressure (BP) and correct for elevation. Acceptance criteria - + 0.02 in. Hg: post-test check - same.] In the absence of pressure readings from an onsite laboratory or other weather station, BP readings will be obtained from the closest airport and corrected for elevation (- 0.10 in. Hg per 100-ft of elevation increase as per Section 6.1.2 of EPA Method 5). 4.5 Field Balance The analytical balance used in the field to determine initial and final silica gel weights was calibrated against Class M weights provided by the Mettler Corporation. 4.6 IMS Equipment and Instrumentation IMS equipment brought ta the site was housed in a dedicated trailer that was transported to the test site and set up adjacent to the sampling location. All equipment {analyzers, calibration gases, and ancillary equipment) was thoroughly checked prior to the jab and the appropriated calibration standards were procured. Daily calibrations and other instrument bias checks were performed in accordance with the specific method followed. AECOM 44
