EXECUTIVE SUMMARY

Global Acoustics were engaged by Wambo Coal (WC) to conduct a noise survey around the

Wambo Coal Mine (WCM), and the Wambo Coal Rail Spur (WCRS).

A noise survey around both the WCM and the WCRS is required quarterly as a condition of

their current development consents (relevant extracts from both are provided in the following

report sections).

Environmental noise monitoring described in this report was undertaken on 26/27 June 2012

for the night measurements, and 8 May, 29 June and 23 July 2012 for the day measurements.

Attended noise monitoring was conducted at a total of five locations for WCM and the WCRS

(see Figure 1) during Quarter 2, 2012. Monitoring was not undertaken at N22 due to a change

of ownership and difficulties gaining access.

The survey purpose is to quantify and describe the existing acoustic environment around the

WCM and WCRS and compare results with relevant development consent conditions or

modelled EIS noise levels.

Three of the six monitoring locations (including N22) are within the Noise Affectation Zone,

as identified in EIS reports (Wambo Development Project EIS (Resource Strategies, 2003), and

Jerrys Plains Coal Terminal and Rail Line Environmental Impact Statement and Statement of

Environmental Effects (CMPS&F, 1997); as such, noise criteria do not apply directly to these

properties. For these locations, measured noise levels from WCM and WCRS are compared

against EIS modelled noise results. Compliance with modelled noise levels at these nearest

receptors indicates compliance with development consent criteria at properties further away

is likely.

Attended monitoring was conducted during day and night hours in accordance with the EPA

‘Industrial Noise Policy’ (INP) guidelines and Australian Standard AS 1055 ‘Acoustics,

Description and Measurement of Environmental Noise’. The duration of each measurement

was 15 minutes. Monitoring was not conducted during the evening period, as evening

consent noise limits are the same as for the night period, and it is considered that night is a

more conservative period in which to monitor.

During day monitoring, WCM was inaudible at four locations. During night monitoring,

WCM was inaudible at two locations. Of the remaining locations where WCM was audible,

there were no exceedances of the LAeq(15 minute) or LA1(1 minute) criteria.

Noise levels from WCRS complied with the LAeq(15 minute) and LA1(1 minute) development

consent criteria or modelled noise levels at all remaining monitoring locations during the

Quarter 2 2012 survey.

It is noted that wind speeds and/or temperature inversion conditions were at levels greater

than which development consent conditions would apply for WCM and WCRS activities in

some instances. In all instances, the predicted EIS noise levels were met regardless.

1 INTRODUCTION

1.1 Background

Global Acoustics were engaged by Wambo Coal (WC) to conduct a noise survey around the

Wambo Coal Mine (WCM), and the Wambo Coal Rail Spur (WCRS). The mine and spur

operate under separate development consents and have been monitored separately.

Reporting, however, has been combined in this document.

Wambo Coal operates both open cut and underground mining operations from their mine at

Warkworth, NSW. The open cut operations include use of heavy mobile equipment in open

cut pits, on haul roads and on waste rock emplacements. The underground operations have

surface facilities. Both operations utilise a coal handling and preparation plant (CHPP)

including conveyors, bins and other material-handling infrastructure.

The WCRS is located between Mt Thorley and Warkworth Village, New South Wales (as

shown in Figure 1) and includes the following components:

� a product coal stockpile and reclaim area, product coal conveyer, train loadout bin, rail loop and a rail spur from the Wambo Coal Mine to Mount Thorley; and

� rail transport of product coal to the market, an intermittent activity that can take place at anytime.

A noise survey around both the WCM and the WCRS is required quarterly as a condition of

their current development consents (relevant extracts from the development consents are

provided in the following report sections).

Environmental noise monitoring described in this report was undertaken on 26/27 June 2012

for the night measurements, and 8 May, 29 June and 23 July 2012 for the day measurements.

Attended noise monitoring was conducted at a total of five locations for WCM and the WCRS

(see Figure 1) during Quarter 2, 2012. Monitoring was not undertaken at N22 due to a change

of ownership and difficulties gaining access.

Three of the six monitoring locations (including N22) are within the Noise Affectation Zone,

as identified in EIS reports (Wambo Development Project EIS (Resource Strategies, 2003), and

Jerrys Plains Coal Terminal and Rail Line Environmental Impact Statement and Statement of

Environmental Effects (CMPS&F, 1997)); as such, noise criteria do not apply directly to these

properties. For these locations, measured noise levels from WCM and WCRS are compared

against EIS modelled noise results. Compliance with modelled noise levels at these nearest

receptors indicates compliance with development consent criteria at properties further away

is likely.

1.3 Terminology

Some definitions of terminology, which may be used in this report, are provided in Table 1.2.

Table 1.2 TERMINOLOGY

Descriptor Definition

LA The A-weighted root mean squared (RMS) noise level at any instant

LA10 The noise level which is exceeded for 10 per cent of the time, which is

approximately the average of the maximum noise levels

LA90 The level exceeded for 90 per cent of the time, which is approximately the

average of the minimum noise levels. The LA90 level is often referred to as the

“background” noise level and is commonly used to determine noise criteria for

assessment purposes

LAeq The average noise energy during a measurement period

dB(A) Noise level measurement units are decibels (dB). The “A” weighting scale is

used to describe human response to noise

SPL Sound pressure level (SPL), fluctuations in pressure measured as 10 times a

logarithmic scale, the reference pressure being 20 micropascals

SEL Sound exposure level (SEL), the A-weighted noise energy during a

measurement period normalised to one second

Hertz (Hz) Cycles per second, the frequency of fluctuations in pressure, sound is usually a

combination of many frequencies together

ABL Assessment background level (ABL), the 10th percentile background noise level

for a single period (day, evening or night) of a 24 hour monitoring period

RBL Rating background level (RBL), the background noise level for a period (day,

evening or night) determined from ABL data

Day This is the period 7:00am to 6:00pm

Evening This is the period 6:00pm to 10:00pm

Night The period 10:00pm to 7:00am

1.4 Wambo Coal Mine Development Consent

WCM was granted consent (DA 305-7-2003) in February 2004, which enables the extension of

current open cut and underground mining operations. The latest modification to this consent

was approved in February 2011.

The Wambo Coal Environmental Management System, Noise Monitoring Programme (Document

EMP011, Rev 3, May 2007) was prepared in accordance with Schedule 4, Consent Condition 9.

The Noise Monitoring Programme indicates that monitoring will be conducted for WCM

activities, and the noise levels to be used for assessment. Monitoring for noise from mining

activities is undertaken at the properties numbered N01, N03, N16, N23 and N24.

It should be noted that properties N01, and N03 are within the Noise Affectation Zone for the

development, and are also subject to acquisition upon request, as detailed in Schedule 4,

Condition 1 of DA 305-7-2003. As such, there are no operational noise goals that apply

directly to these properties. Predicted maximum noise levels from the EIS are therefore used

for comparison at this location except where these levels are less than the minimum criterion

for intrusive noise nominated in the NSW Industrial Noise Policy (35 dB). In these instances,

a criterion of 35 dB is used for assessment. Compliance with predicted levels at this location

indicates likely compliance at properties further away from WCM.

Table 1.3 summarises relevant noise assessment criteria for WCM.

Notes: 1. Criteria from Development Consent DA 305-7-2003;

2. N01, and N03 are within the Zone of Affectation and are acquisition upon request. Modelled noise levels from

EIS are presented for these sites; and

3. Seasonal modelled noise level for Winter/Not winter.

The noise limits identified in Table 1.3 apply under meteorological conditions of:

� wind speeds of up to 3 m/s at 10 metres above ground level; or

� temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2 m/s at 10 metres above ground level.

1.5 Wambo Coal Rail Spur Development Consent

The WCRS consists of two Development Applications (DA’s):

� The Wambo Rail Loop (DA 177-8-2004); and

� The Wambo Rail Line (DA 235/97).

The Wambo Coal Environmental Management System, Noise Monitoring Programme (Document

EMP011, Rev 3, May 2007) was prepared in accordance with Schedule 4, Consent Condition 7.

The Noise Monitoring Programme indicates that monitoring will be conducted for WCRS

activities, and the noise levels to be used for assessment. Monitoring for noise from rail

activities is undertaken at properties numbered N01, N22 and N24 each quarter and at N25

every fifth quarter for rail pass-by noise.

It should be noted that property number N22 is within the Noise Affectation Zone for the

development, and is also subject to acquisition upon request, as detailed in Condition 1 of DA

177-8-2004. As such, the operational noise goals or predictions do not apply directly to this

property. However, due to a change of ownership, monitoring is not currently undertaken at

N22.

It is also noted however that Condition 2 of DA 177-8-2004 indicates that “While the land listed

in Table 1 [of Condition 1] is privately owned, the Applicant shall implement all practicable measures

to ensure that the impacts of the development comply with the predictions in the SEE, and the relevant

conditions in this consent, at any residence on this land, to the satisfaction of the Director-General.”

Therefore, the predicted operational noise levels outlined in the Jerrys Plains Coal Terminal and

Rail Line Environmental Impact Statement and Statement of Environmental Effects (CMPS&F,

1997), as reproduced in Resource Strategies (2005), are referred to in this report.

Table 1.4 summarises relevant noise criteria for the WCRS during operation.

Notes: 1. Seasonal modelled noise level for Winter/Not winter.

The noise limits identified in Table 1.4 apply under meteorological conditions of:

� wind speeds of up to 3 m/s at 10 metres above ground level; or

� temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2 m/s at 10 metres above ground level.

The relevant section from each consent is reproduced in Appendix A.

2 METHODOLOGY

2.1 Assessment Method

2.1.1 Overview

Noise monitoring was conducted at the nearest residences in accordance with the

Environment Protection Authority (EPA) ‘Industrial Noise Policy’ (INP) guidelines and

Australian Standard AS 1055 ‘Acoustics, Description and Measurement of Environmental

Noise’. The mine was in operation for all monitoring. WCRS monitoring was only

conducted while train loading was in progress.

A measurement of LA1(1 minute) corresponds to the highest noise level generated for 0.6

second during one minute. In practical terms this is the highest noise level emitted from the

Wambo Coal noise source during the entire measurement period (i.e. the highest level of the

worst minute during the 15-minute measurement).

As indicated in the consent conditions, the LA1 measurement should be undertaken at 1

metre from the dwelling façade and the LAeq measurement within 30 metres of the dwelling.

However, the direct measurement of noise at 1 metre from the façade is not practical during

monitoring for this project. In most cases, monitoring near the residence is impractical due to

barking dogs or issues with obtaining access. In all cases, measurements for this survey were

undertaken at a suitable and representative location.

Weather forecasts of predicted wind speeds and rainfall are always previewed prior to

commencement of monitoring. Approval to undertake monitoring is then sought from our

client. This procedure gives the best chance of monitoring during suitable atmospheric

conditions. However, forecasts are computer models generated for a general area based on a

number of atmospheric variables. These models are often generated 12 to 24 hours prior to

commencement of monitoring and are only as accurate as the model inputs.

Joel Curran, Rob Kirwan, Amanda Borserio and Imran Khan conducted attended monitoring.

Meteorological data was obtained from the Wambo Coal Mine meteorological station. This

allowed correlation of atmospheric parameters and measured noise levels. Ground level

atmospheric condition measurement was also undertaken during attended monitoring.

2.1.2 Attended Noise Monitoring

Attended noise monitoring was conducted at all sites during day and night hours.

Monitoring was not conducted in the evening period, as consent limits are the same for

evening and night periods, and night time monitoring is considered a more suitable time to

measure the source of interest. The duration of all measurements was 15 minutes.

Page 15: Wambo Coal Mine and Rail Spur - … · 12178_R01 Page i Wambo Coal Mine and Rail Spur Quarter 2, 2012 Environmental Noise Monitoring Reference: 12178_R01.doc Report date: 17 August

12178_R01

Page 9

Attended monitoring is preferred to the use of loggers when determining compliance with

prescribed limits; it allows an accurate determination of the contribution, if any, to measured

noise levels by the source of interest (in this case WCM and / or WCRS).

Weather conditions were recorded at each location during each noise level measurement.

Although the consent is not specific as to where the meteorological data should be sourced,

information from WCM has been used as it is measured with an elevated anemometer as is

required by the consent. The anemometer at WCM is not overly distant from the monitoring

locations and is considered to be representative of the general area. Wind speeds measured

at 10 metres above ground are usually higher than those measured closer to ground level. In

accordance with consent conditions, noise criteria only apply in wind speeds up to 3 metres

per second.

Table 2.1 shows the Beaufort Wind Scale and the corresponding wind speed in metres per

second.

In Table 2.1, number 2 on the scale is approximately the upper limit for the application of

noise criteria under this consent. As this describes, up to 3 metres per second is a light breeze

where leaves rustle gently. In the Hunter Valley during daytime hours it is unusual

(especially during certain months of the year) for such light breezes to occur, particularly

where meteorological stations are situated.

4 DISCUSSION

4.1 Noted Noise Sources

Table 3.2 presents data gathered during attended monitoring. These noise levels are the

result of many sounds reaching the sound level meter microphone during monitoring.

Received levels from various noise sources were noted during attended monitoring and

particular attention was paid to the contribution of WCM or WCRS, if any, to measured

levels. At each receptor location, the LAeq and LA1 (night-time only) for the WCM or WCRS

(in the absence of any other noise) was, where possible, measured directly, or, determined by

frequency analysis. These levels are summarised in Table 3.3, Table 3.4, Table 3.5 and Table

3.6.

From these observations summaries have been derived for each location. The following

chapter sections provide these summaries. Statistical 1/3 octave band analysis of

environmental noise was undertaken, and Figures 7 to 16 display the frequency ranges for

various noise sources at each location for LA1, LA10, LA90, and LAeq. These figures also

provide, graphically, statistical information for these noise levels.

An example is provided as Figure 6 where it can be seen that frogs and insects are generating

noise at frequencies above 1000 Hz; mining noise is at frequencies less than 1000 Hz (this is

typical). Adding levels at frequencies that relate to mining only allows separate statistical

results to be calculated. This analysis cannot always be performed if there are significant

levels of other noise at the same frequencies as mining; this can be dogs, cows, or, most

commonly, road traffic.

It should be noted that the method of summing statistical values up to a cutoff frequency can

overstate the LA1result by a small margin but is entirely accurate for LAeq.

A low-level continuum from WCM was audible during the measurement but not measurable

due to the presence of road traffic noise. Reverse alarms were noted at low levels twice and

rear dump truck engine noise three times.

Road traffic tyre and engine noise was responsible for all measured levels.

Birds, insects, an aircraft, breeze in foliage and on the microphone were also noted.

5 SUMMARY

5.1 Summary

Environmental noise monitoring described in this report was undertaken on 26/27 June 2012

for the night measurements, and 8 May, 29 June and 23 July 2012 for the day measurements.

During day monitoring, WCM was inaudible at four locations. During night monitoring,

WCM was inaudible at two locations. Of the remaining locations where WCM was audible,

there were no exceedances of the LAeq(15 minute) or LA1(1 minute) criteria.

Noise levels from WCRS complied with the LAeq(15 minute) and LA1(1 minute) development

consent criteria or modelled noise levels at all remaining monitoring locations during the

Quarter 2 2012 survey.

It is noted that wind speeds and/or temperature inversion conditions were at levels greater

than which development consent conditions would apply for WCM and WCRS activities in

some instances. In all instances, the predicted EIS noise levels were met regardless.

Notes:

a) Noise from the development is to be measured at the most affected point or within the

residential boundary, or at the most affected point within 30 metres of a dwelling (rural

situations) where the dwelling is more than 30 metres from the boundary, to determine

compliance with the LAeq(15 minute) noise limits in the above table. Where it can be

demonstrated that direct measurement of noise from the development is impractical, the DEC

may accept alternative means of determining compliance (see Chapter 11 of the NSW

Industrial Noise Policy). The modification factors in Section 4 of the NSW Industrial Noise

Policy shall also be applied to the measured noise levels where applicable.

b) Noise from the development is to be measured at 1 metre from the dwelling façade to

determine compliance with the LA1(1 minute) noise limits in the above table.

c) The noise emission limits identified in the above table apply under meteorological conditions

of:

• wind speeds of up to 3 m/s at 10 metres above ground level; or

• temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2 m/s

at 10 metres above ground level.
