Box 144820 Salt Lake City, Utah 84114-4820 Attn: Jay Morris, Director Subject: Submission of Stack Test Protocol and Test Dates as per Approval Order DAQE- AN101590008-17. Dear Mr. Morris, In compliance with Approval Order DAQE-AN101590008-17, we submit herewith the Stack Test protocol and test dates for the North Davis Sewer District’s Cogeneration Engine #3 Lean Burn Engine. The test schedule is planned for May 6th and 7th 2024. Please contact me at (801) 728-6830 if you have questions or comments. Sincerely, Myron Bachman Plant Superintendent Enclosures cc: Chad Gilgen Scott Vineyard David Hatch NORTH DAVIS SEWER DISTRICT COMPLIANCE EMISSION TESTING PROTOCOL FOR NOx AND CO EMISSIONS AT NORTH DAVIS SEWER DISTRICT (NDSD) SYRACUSE, UTAH Waukesha 923 kW Lean Burn Engine Project Organization and Responsibility The following personnel and the testing contractor are presently anticipated to be involved in the testing program. The Utah Division of Air Quality (DAQ) may have their own personnel to observe all phases including the process. Company NDSD 4252 West 2200 South Syracuse, UT 84075 Contacts Myron Bachman (801) 825-0712 Test Contractor: TETCO 391 East 620 South American Fork, UT 84003 Dean Kitchen 801- 492-9106 Facility Location and Description NDSD operates a water treatment plant in Syracuse, Utah. The process includes collecting digester gas which is prepared as a fuel gas for onsite engines. Test Objective This test is being conducted to comply with the testing requirements of the Waukesha 7100GL, 923 kW engine. The engine is to be tested at least once every 5 years for NOx and CO emissions. The results shall be reported in terms of pounds per hour (lb/hr) and grams per brake horse- power-hour (g/bHp-hr). Testing is to be conducted according to the principals of EPA Methods 1-4, 7E, and 10. Test Schedule It is planned to complete all testing May 6-7, 2024. The test crew will set up the testing equipment May 6th and then begin testing if time and production permits. If needed, testing may be conducted on May 7th. The testing crew will take preliminary velocity and cyclonic flow measurements prior to beginning the stack test. If desired a pretest meeting may be scheduled by DAQ or NDSD. Operational Data and Instrumentation The engine will operate normally during the test project. All pertinent process data will be made available to DAQ personnel. Test Procedures Three test runs will be completed on the exhaust stack. Stack testing will be EPA Methods 1-4, 7E, and 10 as specified in 40 CFR 60, Appendix A. One Method 4 test run may span up to three Method 7E and 10 test runs. Specific procedures are as follows: EPA Methods 1-4 1.The stack inside diameter is 13 inches. Sample ports are located 160 inches downstream and approximately 104 inches upstream from any flow disturbance. It is planned to sample four sample points per port (eight total points). The number of sample points is based upon Method 1 for a nonparticulate traverse. 2.EPA Method 2 will be used to determine the gas stream velocity. Type “S” pitot tubes will be used with a Cp factor of 0.84. Dual inclined/vertical manometers with graduations of 0.01 inches of water will be used. If necessary a more sensitive manometer with graduations of 0.005 may be used. The absence of cyclonic flow will be verified prior to beginning the test. 3.EPA Method 3A will be used to measure the CO2 and O2 concentrations to determine the gas stream dry molecular weight. These samples will be taken with the NOx and CO sampling train. Method 3 maybe used as a backup for Method 3A. 4.EPA Method 4 will be followed to determine the gas stream moisture content. Test run time and sample flow rate will be sufficient to sample at least 21 dscf. One Method 4 may span up to three Method 7E and 10 test runs. 5.Probe liners will be 316 stainless steel. 6.The barometric pressure will be measured with a barometer which is periodically checked against a mercury barometer. The barometer will be checked prior to testing to assure an accurate barometric pressure. 7.Calibration data is submitted with this protocol. Any calibration that is not current will be re-calibrated prior to the test dates. 8.Any necessary preparation and clean-up by the contractor will be performed in the contractor's sampling trailer or a clean area on NDSD property. 9.Verbal results will be reported to NDSD on site. The written reports will submitted within 30 days following completion of the tests. Gaseous Analyzer Measurements Gaseous analyzers will be used to measure the CO2/O2, NOx and CO concentrations levels according to EPA Methods 3A, 7E, and 10 respectfully. The gaseous analyzer measurements will be taken simultaneously with EPA Methods 1-4. EPA Protocol 1 gases will be used as a standard for all analyzers. Bias checks, calibration drift, zero drift and calibration error will follow the specified guidelines of EPA Method 7E. The gas analyzer sampling train will consist of the following: an in-stack glass fiber filter, heated stainless steel probe, Teflon heated sampling line to the water removal system, water removal system, Teflon transport lines, gas manifold, and out of stack Teflon filter after the gas manifold but prior to analyzer. The sampling train is built such that the sampled gas only comes in contact with inert materials, i.e., Teflon, stainless steel, and glass. A data logger will be used to provide a recorded gas concentration measurements that will be averaged on a minute basis. A stratification check will be performed to determine the number and location of the gaseous analyzer sample points. Potential Hazards Moving Equipment No Hot Equipment Yes Chemical Chlorine on site Other Biological. Wash hands frequently and eat only in designated areas. Quality Assurance All testing and analysis in these compliance tests will be conducted according to Methods 1-4, 7E, 10, and appropriate sections of the EPA Quality Assurance Handbook for Air Pollution Measurement Systems Volume III. Reporting Complete copies of raw data, calculations and summary of test will be included in the test report. All process and production data will be recorded and retained for inspection and copying by DAQ. Appendix A Calibration Data and Sample Equations METHOD 5 DRY GAS METER CALIBRATION USING CRITICAL ORIFICES 1) Select three critical orifices to calibrate the dry gas meter which bracket the expected operating range. 2) Record barometric pressure before and after calibration procedure. 3) Run at tested vacuum (from Orifice Calibration Report), for a period of time necessary to achieve a minimum total volume of 5 cubic feet. 4) Record data and information in the GREEN cells, YELLOW cells are calculated.
