The Utah Division of Air Quality (DAQ) and EPA may have their own personnel to observe all phases including the process. Company McWane Ductile P O Box l2l9 Provo, UT 84603 Test Contractor: TETCO 391 East 620 South American Fork, UT 84003 Contacts Christy Webster 801 623-4224 Dean Kitchen 801 492-9106 Facilitv Location and Description McWane Ductile operates a foundry located in Utah County between Springville and Provo, Utah. The facility produces ductile iron pipe. Test Obiective This test project is being conducted to measure the NOx, SOz, and CO emissions from the Cupola Luhr Baghouse exhaust. The NO*, SOz, and CO emissions will be measured as directed in the facility Approval Order (DAQE-ANO107940040-25) and Title V Permit, Permit Number 49000 I 7004, dated November 8, 2022. Test Dates It is planned to complete the test project April 2l -22,2025. Testing is anticipated to begin at approximately 6:00 a.m. the moming of April 22"d.The testing crew will take preliminary measurements prior to beginning the test. If necessary, a pretest meeting may be scheduled by DAQ or McWane Ductile. Test Procedures Test Method ldentification Three test runs will be completed on the Cupola Luhr Baghouse exhaust stack. Testing will be for SOz, NO*, and CO emissions according to EPA Methods 6C,78, and l0 respectfully. Methods l-4 will run concurrently with the NOx, SOz, and CO analyzers and will provide the necessary stack flow rate measurements for calculating the pollutant emission rates. Specific procedures are as follows: EPA Methodl l-4 l.The sample location and number of sample points will comply with the requirements of EPA Method I . The stack inside diameter is 70.25 inches. The number of sample points will be 16, eight per port. The ports are located 6.1 5 diameters (36-feet) downstream from a disturbance, and 2.73 diameters ( l6-feet) upstream distance from the stack exit. EPA Method 2 will be used to determine the gas stream velocity. 'lype "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 the measured pressure differential is below 0.05 inches of water a more sensitive manometer will be used with graduation marks of 0.005 inches of water. Direction of gas flow will be checked for cyclonics prior to testing. EPA Method 3 will be used to determine the gas stream dry molecular weight. An integrated flue gas sample will be taken from the exhaust line after the dry gas meter orifice during each test run and analyzed for COz and Oz concentrations at the completion of the test with an Orsat to determine the molecular weight of the effluent gas stream. EPA Method 4 will be followed to determine the gas stream moisture content. The probe liners will be 316 grade stainless steel. borosilicate glass or quartz. 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. Calibration data is provided with this protocol in Appendix B. Equipment calibrations that fall past due prior to the test dates will be recalibrated prior to being used. Any calibrations not included with this protocol, such as new or additional equipment, will be made available to DAQ representatives upon request. Any necessary preparation and clean-up by the contractor will be performed in the contractor's sampling trailer or a clean area on McWane Ductile's property. 2. 3. 4. 5. 6. 7. 8. l. EPA Methods 6C,7E, and 10 Gaseous analyzers will be used to measure the NO*, SOz. and CO levels simultaneously with mass flow measurements. The gas analyzer sampling train will consist of the following: an in-stack glass fiber filter, heated stainless steel probe, heated Teflon sampling line to 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. EPA Protocol I gases will be used as standards with dry nitrogen as a zero gas. A data logger will record gas concentration averages on at least 60-second averages. Only valid gas analyzer data will be used for emission calculations. Before commencement or resuming testing (i.e.. after port change) the gas analyzers will be allowed to stabilize as per applicable test method system requirements. Bias checks, calibration drift. zero drift. system response. and calibration error will follow the specified guidelines of EPA Methods 6C.7b.. and 10. A stratification check will be performed prior to the test as required by Methods 6C.7F,, and 10. It is planned to run the NO* analyzer on the 0-250 ppm range with a high-level calibration gas of approximately 230 ppm. The NO* analyzer is model CLA-510 Horiba Instruments, serial number 4l 67908003 I , manufactured in 2001 . A copy of determined interference responses is included with this protocol. A NO* converter efficiency check will be conducted at the beginning of each day testing occurs. It is planned to run the SOz analyzer on the 0-50 ppm range with a high-level calibration gas of approximately 45 ppm. The SOz analyzer is model ZRE CAI. serial number AlG6200T, manufactured in 2012. A copy of determined interference responses is included with this protocol. It is planned to run the CO analyzer on the 0- I 00 ppm range with a high-level calibration gas of approximately 90 ppm. The CO analyzer is model VIA-5 l0 Horiba Instruments, serial number 43223490033, manufactured in 1995. A copy of factory determined interference responses is included with this protocol. Additional Procedures l. All current calibration data is submitted with this protocol. Any calibration that is not current will be re-calibrated prior to the test dates. 2. 3. 4. 5. 6. 7. 3. Verbal gaseous results will be reported to McWane Ductile on site. The written reports will submitted from TETCO to McWane Ductile within 30 days following completion of the tests. McWane Ductile will submit the final report to DAQ within 60-days following the completion of the test. Process Description Descrintion of Process McWane Ductile produces ductile iron products for utilities. Products include pipe in 6" through 30" diameter for water distribution and utility poles. The iron pipe process includes melting, core preparation, casting, annealing, lining, coating, and special lining operations. As part of the manufacturing process, the plant operates a cupola or vertical cylindrical shaft furnace. The melting process includes a state of the art air pollution control system, which includes a recuperator and baghouse. A schematic diagram of the stack is included in Appendix A. Operational Data and Instrumentation All operational and instrumentation data will be made available to state agency personnel. Applicable production records will be included and submitted with the report. These records are: o Batch Protocol Reporto Batch Balance Reporto CO Combustor Temperature Chart The current method of determining iron production is by monitoring charging into the cupola. The iron production rate will be determined by ensuring that the cupola is full at the beginning of a test run and then summing the addition of iron to the cupola during the test run to maintain a "full" level. Testing will occur only when McWane Ducltile personnel have verified that production is at the desired target production rate.
