3 PROCESS EMISSIONS MONITORING - PARAMETER, SAMPLING AND ANALYSIS METHOD AND ANALYSIS LABORATORY 3.1 Test Methods and Analysis References All sampling and monitoring was performed by SLR Consulting Australia Pty Ltd (SLR Consulting) unless otherwise specified. The following table outlines for each parameter requested to be tested, the relevant test method for sampling and analysis and the NATA Accredited Laboratory that completed the analysis. All associated NATA endorsed Test Reports/Certificates of Analysis are provided separately in Appendix A. 3.1.1 Point Source Emissions Parameter State Test Method Number for Sampling and Analysis NATA Laboratory Analysis By: NATA Accreditation No. & Report No. Sampling Location NSW TM-1, AS4323.1 Velocity NSW TM-2, USEPA M2A, 2C Duct Temperature NSW TM-2, USEPA M2, 2C Volumetric Flow Rate NSW TM-2, USEPA M2A, 2C Duct Pressure NSW TM-2, USEPA M2, 2C Dry Gas Density NSW TM-23, USEPA M3 Moisture NSW TM-22, USEPA M4 Molecular Weight of Stack Gases NSW TM-23, USEPA M3 Oxygen NSW TM-25, USEPA M3A Oxides of Nitrogen NSW TM-11, USEPA M7E, 7D Volatile Organic Compounds NSW TM-34, USEPA M18 Testsafe Australia, Accreditation No. 3726, Report No. 2014-2705 610.14661-TR1R0.docx Page 2 of 8
3.2 Deviations from Test Methods There were no deviations to the test methods. 3.3 Sampling Times As per the relevant test reference method or State requirement. 3.4 Reference Conditions As per relevant test reference method, State requirement, or Environment Protection Licence or equivalent. 3.5 Identification All samples are individual labelled with reference number, location, sampling date and times. 3.6 Sampling Plane Details Ideal sampling positions: In the absence of cyclonic flow activity ideal sampling plane conditions will be found to exit at 7-8 diameters downstream and 2-3 diameters upstream from a flow disturbance. However, in most cases, a suitable sampling plane will be a position fitting the minimum criteria specified in Table 1 of AS4323.1. Non Ideal sampling position: If the measurement near a bend is unavoidable, the sampling position shall be greater than one duct diameter upstream of the bend or greater than two duct diameters downstream of the bend. When the criteria in Table 1 of AS4323.1 cannot be met, a greater number of sampling points shall be used in order to retain as much accuracy as is practicable. 2A 2B 1A 1B 610.14661-TR1R0.docx Page 3 of 8
