5 1 Introduction Stratford Coal Pty Limited (DCPL), a wholly owned subsidiary of Yancoal Australia Limited (Yancoal), has commissioned SLR Consulting Australia Pty Ltd (SLR) to conduct monthly noise monitoring for the Stratford Mining Complex (SMC) operations guided by the requirements of the (Stratford Extension Project) Noise Management Plan (NMP), Document No. NMP-R01-A, dated March This report presents the results and findings from the operator-attended noise surveys conducted between Monday 24 and Tuesday 25. It is understood that the SMC collectively comprises the Stratford Coal Mine (SCM), the Bowens Road North Open Cut (BRNOC) and the associated coal processing and handling facilities. Run-of-mine (ROM) coal from the Duralie Coal Mine (DCM) is transported by rail to the SMC, where it is processed along with ROM coal from the SCM and BRNOC. SMC coal is then loaded and railed on the North Coast Railway to the port of Newcastle. The objectives of the noise monitoring programme for this operating period were as follows: Conduct three rounds of external operator-attended noise measurements at the six nominated locations, representative of receivers in the area surrounding the SMC. The six nominated external operator-attended noise measurement locations are: Atkins Off Wenhams Cox Road, Stratford Clarke Off Wenhams Cox Road, Stratford Hall Upper Avon Road Lowrey Off Crowthers Road, Stratford Pryce Jones The Bucketts Way, Craven Van der Drift Wood Street. Stratford Noise monitoring will occur for a day, evening and night period. The day, evening and night periods being those defined in the NSW Industrial Noise Policy (EPA 2000). The operator will quantify and characterise the maximum (LAmax) and the intrusive (LAeq and LCeq) noise level contributions from SMC operations over a 15 minute measurement period. In addition, the operator will quantify and characterise the overall levels of ambient noise (i.e. LAmax, LA1, LA10, LA50, LA90, and LAeq) over the 15 minute measurement interval. Assess the noise emissions of SMC and determine compliance with respect to the limits contained in the NMP. In addition to monthly noise monitoring at the nominated residential receivers, the NMP requires quarterly noise monitoring of rail activity and verification monitoring of the Real Time Noise Monitor (RTNM) network. RTNM verification and rail noise monitoring was conducted throughout the quarter ending. The following report uses specialist acoustic terminology. An explanation of common terms is provided in Appendix A. Page 5

Table 1 Noise Limits for the Nominated Noise Monitoring Locations Locality Intrusiveness Criteria LAeq(15minute) Night LA1(1minute) Criterion Day Evening Night Night Atkins Clarke 1, Hall Lowrey Pryce Jones Van der Drift Note 1: Note 2: Owned by Stratford Coal Pty Ltd Criteria adopted from Bagnall as a guide only and are not definitive at this location. Note 3: Land subject to acquisition upon request. 2.4 Assessment of Low-frequency Emissions To address the low-frequency noise assessment issues raised in the 2014 Independent Environmental Audit, as outlined in the VIPAC letter (29N TNT , dated 26 February 2015), the following analysis of the operator-attended monitoring data was proposed: a full L Ceq minus L Aeq spectrum low frequency analysis will be conducted on all noise compliance measurements where the mine noise contribution is deemed to be the dominant noise source. This will be conducted in accordance with the guidance set out in the INP in accordance with the requirements of Development Consent 23-98/99 Schedule 3 Condition 7(a) and Development Consent Schedule 2 Condition 6.4C(a)(i). The low-frequency analysis proposed above shall also serve to meet the Compliance Monitoring requirement of Section 5(d) of Appendix 6 Noise Compliance Assessment of the Stratford Extension Project Development Consent (SSD-4966, dated 29 May 2015), that states: the use of an appropriate modifying factor for low frequency noise to be applied during compliance testing at any individual residence if low frequency noise is present (in accordance with the INP) and before comparison with the specified noise levels in the consent. Low frequency noise is assessed under the NSW Noise Policy for Industry (NPfI) methodology following its introduction in 2017, and replaces the INP methodology. A full LCeq minus LAeq and low frequency 1/3 octave analysis of SMC noise contributions was conducted at the following locations: Lowrey - Night Page 9

10 Van der Drift - Night At all other locations SMC was not audible and/or significantly below the relevant noise criteria and is therefore not addressed further. The results of the operator attended noise measurements presented in Section Rail Noise Goals The NMP has adopted ARTC s EPL 3142 noise goals as criteria for the assessment of SMC rail transport noise. The noise objectives specified in ARTC s EPL 3142 apply at 1 m from the façade of affected residential properties and are provided in Table 2. Table 2 ARTC EPL 3142 Noise Objectives Descriptor Rail Traffic Goal dba Daytime/Evening LAeq(15hour) 65 Night-time LAeq(9hour) 60 Maximum Pass-by LAmax 85 3 Operational Noise Monitoring Methodology 3.1 General Requirements All acoustic instrumentation employed throughout the monitoring programme has been designed to comply with the requirements of AS IEC Electroacoustics Sound level meters Specifications, AS IEC , AS IEC and carried current NATA or manufacturer calibration certificates. Instrument calibration was checked before and after each measurement survey, with the variation in calibrated levels not exceeding ±0.5 dba. All operator-attended noise measurements were conducted using a one-third octave integrating Brüel & Kjær Type 2270 (s/n ) and Svantek SVAN957 (s/n 23815) sound level meters together with a Svantek SV30A acoustical calibrator (s/n 24713). 3.2 Operator-attended Noise Monitoring Locations Noise monitoring was conducted in accordance with the requirements of the NMP. Operator-attended noise measurements were conducted during the day, evening and night-time period for a minimum of 15 minutes per period at each of the six nominated residential noise monitoring locations. The details of the operator-attended SMC operational noise monitoring locations are contained within Table 3 and shown generally in Figure 1. During the operator-attended noise measurements, the character and relative contribution of ambient noise sources and SMC contributions were determined by observations on site. Page 10

Page 15

16 Mining operations in the Avon North open cut were the dominant noise source during the day, evening and night-time monitoring periods. SMC operations generated an LAeq(15minute) noise contribution of 44 dba, 23 dba and 34 dba during the day, evening and night-time, respectively. During the night time monitoring period the operation of a dozer generated LAmax noise levels of up to 47 dba at the monitoring location. Taking into account the distance between the observed SMC operations and the nearest privately owned residence Bagnall, LAeq(15minute) noise levels of 36 dba during the daytime and less than <25 during the evening and night are predicted at the Bagnall location. LAmax noise levels are predicted to be 35 dba. It should be noted that this figure is considered conservative as it takes into account corrections for propagation distance only (i.e. no shielding due to topography or atmospheric absorption). As such SMC operations are considered to be compliant at the Bagnall location. Page 16
