Introduction 1

1.0 Introduction

Glencore Integra Underground (IUG) is located in the Hunter coalfields of New South Wales (NSW), approximately 12 kilometres north-west of Singleton in the locality of Camberwell (refer to Figure 1.1). IUG is owned and managed by HV Coking Coal Pty Ltd (HVCC) which is a wholly-owned subsidiary business unit of Glencore Coal Pty Limited (Glencore).

Underground mining operations at IUG are approved at a maximum extraction rate of 4.5 million tonnes per annum (Mtpa) of run-of-mine (ROM) coal until 31 December 2035 under Project Approval PA 08_0101.

1.1 Project Background

IUG operates in an area dominated by coal mining and mining-related development. It lies immediately to the south-east of Glencore’s Mount Owen Complex while Ashton Mine operates to the west and south-west. The residential areas of Camberwell Village and Wattle Ponds are located to the west and east of the mine respectively. There are a number of residences situated in the immediate vicinity of IUG (refer to Figure 1.2).

In late 2015, HVCC acquired all assets associated with the IUG, which had been placed under care and maintenance in May 2014. During this time environmental management of the site was maintained under a care and maintenance environmental management system.

Prior to HVCC’s purchase of the mine, it formed part of the larger Integra Mine Complex. This complex comprised both underground and open cut operations and operated under a single project approval instrument which combined the project approvals for the Integra Underground (PA 08_0101) and Integra Open Cut (PA 08_0102). Following the separate sale of the underground and open cut, the combined project approval was modified to once again separate the approvals. IUG now operates under PA 08_0101 MOD 6.

HVCC recommenced underground operations early in 2017, with development resuming in February 2017 and longwall extraction resuming in May 2017.

1.2 Scope

This Noise Monitoring Report has been prepared by Umwelt (Australia) Pty Limited (Umwelt) on behalf of HVCC for IUG.

The noise monitoring and reporting requirements for IUG are outlined in the Integra Underground Mine Project Approval (PA 08_0101 MOD 6) and Environment Protection Licence (EPL) 3390, and are guided by the Integra Underground Noise Management Plan (Glencore, 2017).

Due to the underground nature of the mine, generation of noise emissions as a result of IUG’s operations will generally be limited to the following sources:

Ventilation fans, compressor and gas flares located on Forest Road;

Haulage of coal from the ROM coal stockpile to the project boundary. Bloomfield operations then transports the coal to the CHPP on their internal haul road via haul trucks; and


Introduction 2

Minor surface disturbance activities, including:

o Exploration activities;

o Gas drainage works;

o Minor subsidence remediation works; and

o Construction of erosion and sedimentation controls.

This report presents the results of the Winter 2017 (01 June 2017 to 31 August 2017) noise monitoring undertaken as part of the noise monitoring program for IUG. The monitoring results will be incorporated into the Annual Review required to be prepared under the relevant project approval conditions for IUG.

A glossary of terms and abbreviations used in this report is provided in Appendix 1.

Compliance Assessment Methodology 8

3.0 Compliance Assessment Methodology

The compliance assessment process addresses compliance with the noise impact assessment criteria (Table 2.1 and Table 2.2) and is only undertaken for periods during which the meteorological conditions are consistent with those under which the criteria apply (refer to Table 2.3). Attended noise monitoring has been used to quantify and describe the acoustic environment around IUG. The compliance assessment methodology involved the following activities:

Attended noise monitoring surveys at each of the monitoring locations during the night-time period to measure the ambient noise levels in the surrounding region and to assess IUG contributions (reported as LAeq, 15 minute) to the measured noise levels.

Comparison of the attended noise monitoring results with the relevant noise impact assessment criteria to assess compliance of IUG operations with the relevant project approvals and EPL criteria.

Comparison of the LA1, 1 minute night-time attended noise monitoring results with the night-time sleep disturbance criteria outlined in the relevant project approvals and EPL criteria.


Attended Noise Monitoring 9

4.0 Attended Noise Monitoring

4.1 Attended Noise Monitoring Program

Attended noise monitoring for IUG is conducted in accordance with the NSW Environment Protection Authority (EPA) Industrial Noise Policy (INP) (2000) guidelines and the Australian Standard AS1055-1997, Acoustics – Description and Measurement of Environmental Noise, Part 1 General Procedures.

In accordance with the Integra Underground Noise Management Plan (Glencore, 2017), for each measurement the following information within the raw dataset is recorded:

Operators name;

Monitoring location;

Dates and times that monitoring began and ended at each location;

Height of the microphone above the ground and, if relevant, distances to building façades or property boundaries;

Qualitative/quantitative meteorological data such as temperature, wind speed, wind direction, cloud cover, humidity, fog, rainfall etc.;

Instrument calibration details before and after measurement;

The LAeq,15 minute noise level for the measurement period;

Statistical noise level descriptors over the measurement period, LAmin, LA90, LA10, LA1 and LAmax;

LA1, 1 minute noise levels (to allow comparison with sleep disturbance criteria);

Notes that identify the noise source(s) that contribute to peak noise levels (LA1 or LAmax);

An estimate of noise contribution from operations at IUG;

An estimate of the noise contribution from other audible mines, if any;

Measurement of C-weighted and A-weighted levels to assess low frequency noise in accordance with Section 4 of the INP (a 5 dB correction is applicable if the difference between the site’s C-weighted and A-weighted level is 15 dB or more);

Data suitable for assessing the relative contribution of mine-generated noise to the overall noise being measured by using a low-pass filter (i.e. consideration of frequencies up to and including 1000 Hz); and

Recommendations and comments, where considered appropriate.

Monitoring is conducted in accordance with the provisions of Appendix 5 of PA 08_0101 MOD 6.

The purpose of attended noise surveys is to quantify and describe the ambient noise environment in the region surrounding IUG and to estimate the contribution of mining-related activities to the ambient noise levels.



Attended noise monitoring is undertaken at the locations presented in Table 4.1 and Figure 1.2 and provides the following noise-related information:

Noise data that will assist in identifying noise contributions from IUG;

Noise data that is representative of noise levels at receivers within the localised area; and

Reference noise data that will assist in determining compliance at other receiver locations.

During the attended monitoring session, noise measurements are taken with a Svantek 959 noise and vibration analyser (Serial Number 12918) which is calibrated on site using a Brüel and Kjær Type 4231 Noise Meter Calibrator (Serial Number 2130702) in accordance with the requirements of AS1055-1997. Calibration certificates are included in Appendix 2. The noise meter is run using three measurement profiles (Linear, C Weighting and A Weighting) and records A-weighted 1/3 octave noise levels at 1 second intervals over a 15 minute measurement period. Raw data is available on request.

During the attended monitoring session the operator maintains a log of noise-related events that occur including various noise sources contributing to the ambient noise environment. Particular attention is paid to the contribution of the operations associated with IUG.

Meteorological data for the attended monitoring periods is collected from a Kestrel 4500 weather monitor (Serial Number 665400), positioned within 5 metres and at a corresponding height to the noise monitoring microphone (approximately 1.3 metres from the ground). Supplementary meteorological data is obtained, when required, from Mt Owen Complex’s SentineX meteorological stations.



4.2 Attended Noise Monitoring Results for Winter 2017

Attended noise monitoring sessions, comprising of night time assessment periods only, were conducted at nine locations (refer to Table 4.1 and Figure 1.2) during the winter 2017 assessment period in the region surrounding IUG.

The monitoring results are presented graphically in Appendix 3, and include:

Recorded A-weighted 1/3 octave noise levels at 1 second intervals over the 15 minute measurement period

Results of a 1000 Hz low pass filter at 1 second intervals over the 15 minute measurement period

Assessment of the maximum LA1,1minute noise level recorded over the 15 minute measurement period

LAeq, 15 minute, LA10, 15 minute and LA90, 15 minute noise levels for the 15 minute measurement period

Operator comments regarding any extraneous noise sources contributing to the ambient noise levels.

4.3 Monitoring Results Summary

The results of the winter attended noise monitoring session, presented in Appendix 3, indicate that under the meteorological conditions at the time of monitoring, IUG was compliant at all monitoring locations during the monitoring session with the relevant night time LAeq, 15 minute and LA1, 1 minute noise assessment criteria.

The noise impact assessment criteria for IUG are summarised in Table 2.1 and Table 2.2.

1/3 Octave Single octave bands divided into three parts.

Octave A division of the frequency range into bands, the upper frequency limit of each band being twice the lower frequency limit.

ABL Assessment background level – A single-figure background noise level representing each assessment period – day, evening and night (that is, three assessment background levels are determined for each 24 hour period of the monitoring period). It is determined by taking the lowest 10th percentile of the L90 level for each assessment period.

Ambient Noise The noise associated with a given environment. Typically a composite of sounds from many sources located both near and far where no particular sound is dominant.

A Weighting A standard weighting of the audible frequencies designed to reflect the response of the human ear to noise.

dB(A), dBA Decibels A-weighted.

dB(L), dB(Lin) Decibels Linear or decibels Z-weighted.

Decibel (dB) The units of sound level and noise exposure measurement where a step of 10 dB is a ten-fold increase in intensity or sound energy and actually sounds a little more than twice as loud.

Hertz (Hz) The measure of frequency of sound wave oscillations per second – one oscillation per second equals 1 hertz.

LA10 The percentile sound pressure level exceeded for 10 per cent of the measurement period with 'A' frequency weighting calculated by statistical analysis. Typically used to assess the impact of an existing operation on a receiver area and is referred to as the cumulative noise levels at the receiver attributable to the noise source.

LA90 Background Noise Level. The percentile sound pressure level exceeded for 90 per cent of the measurement period with 'A' frequency weighting calculated by statistical analysis.

LAmax The maximum of the sound pressure levels recorded over an interval of one second.

LA1,1minute The measure of the short duration high-level noises that cause sleep arousal. The noise level is measured as the percentile sound pressure level that is exceeded one per cent of measurement period with 'A' frequency weighting calculated by statistical analysis during a measurement time interval of one minute.


Appendix 1 2

LAeq,t Equivalent continuous sound pressure level – The value of the sound pressure level of a continuous steady noise that, a measurement interval of time (t), has the same mean square sound pressure as the sound under consideration whose level varies with time. Usually measured in dB with 'A' weighting.

LAn Percentile level – A measure of the fluctuation of the sound pressure level which is exceeded ‘n’ per cent of the observation time.

RBL Rating background level – The overall single figure background level representing each assessment period over the whole monitoring period determined by taking the median of the ABLs found for each assessment period.

SPL (dBA) Noise: Sound pressure level – The basic measure of noise loudness. The level of the root-mean-square sound pressure in decibels given by:

SPL = 10.log10 (p/p0)2

where p is the rms sound pressure in pascals and p0 is the sound reference pressure at 20 µPa. decibels.

SWL Sound power level – a measure of the energy emitted from a source as sound and is given by:

SWL = 10.log10 (W/W0)

where W is the sound power in watts and W0 is the sound reference power at 10-12 watts.
