2 PROJECT APPROVAL AND CRITERIA 

A project approval and licence apply to the Mangoola Coal Project. 

2.1 Development Consent 

Xstrata Mangoola Pty Limited obtained a modification to the project approval in February 

2010 (06-0014 MOD 5) to continue open cut mining. Schedule 3, Conditions 3 to 11 of the 

approval contains the noise requirements. 

The noise sections of the approval are reproduced in Appendix A. 

2.2 Environment protection Licence 

Mangoola Coal holds an Office of Environment & Heritage (OEH, formerly the Department 

of Environment, Climate Change and Water) Environment Protection Licence (EPL) No. 

12894 for coal mining, crushing, grinding and separating. Noise requirements are detailed in 

L6 of the licence. 

The noise sections of the licence are reproduced in Appendix A. 

2.3 Noise Monitoring Program 

The Noise Monitoring Program (NMP) for Mangoola Coal was finalised in September 2008 

and last reviewed in August 2010. The latest version details the monitoring requirements 

associated with the operational phase of the mine as well as ongoing construction activities. 

2.4 Project Specific Criteria 

Activities have been assessed against criteria from Table 1 of the project approval, the limiting 

of which are the impact assessment criteria as set out in Table 2.1.

3 METHODOLOGY 

3.1 Attended Noise Monitoring 

Attended monitoring was conducted in accordance with OEH ‘Industrial Noise Policy’ (INP) 

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

Environmental Noise’. Atmospheric condition measurement was also undertaken. The 

duration of each measurement was 15 minutes. 

Attended monitoring is preferred to the use of noise 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 Mangoola Coal). 

The equipment detailed in Table 3.1 was used to measure environmental noise levels.

Rion NC-74 sound level calibrator 50941314 31/10/2013 

Calibration certificates are provided in Appendix B. 

Meteorological data was obtained from Mangoola Coal meteorological stations. This allowed 

correlation of atmospheric parameters and measured noise levels. Sigma theta is used to 

calculate vertical temperature gradient (VTG) in accordance with procedures detailed in the 

INP. 

Met data used in this report was sourced from Mangoola Coal’s north and south 

meteorological stations and is provided in Appendix C.

5 DISCUSSION 

5.1 Noted Noise Sources 

Table 4.1 to Table 4.4 present 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 extent of Mangoola Coal’s contribution, if any, to 

measured levels. At each receptor location, Mangoola Coal’s L Aeq(15 minute) (in the absence 

of any other noise) was, where possible, measured directly, or, determined by frequency 

analysis. 

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

report sections provide these summaries. 

Statistical 1/3 octave band analysis of 

environmental noise was undertaken, and the charts following in this section display the 

frequency ranges for various noise sources at each location for L A1, L A10 , L A90 , and L Aeq . 

These figures also provide, graphically, statistical information for these noise levels. 

An example is provided as Figure 2 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 cut-off frequency can 

overstate the L A1 result by a small margin but is entirely accurate for L Aeq .

the measured noise levels where applicable. 

As defined in the Industrial Noise Policy: 

Low frequency noise contains major components within the low frequency range (20 Hz to 250 

Hz) of the frequency spectrum. 

As detailed in Chapter 4 of the INP, low frequency noise should be assessed by measuring the 

C-weighted and A-weighted level over the same time period. The correction/penalty of 5 dB 

is to applied if the difference between the two levels is 15 dB or more. 

Low frequency noise can also be assessed against criteria specified in the paper "A Simple 

Method for Low Frequency Noise Emission Assessment ”(Broner JLFNV Vol29-1 pp1-14 

2010). If the total predicted C – weighted noise level at a receptor exceeds the relevant 

criterion; a 5 dB penalty (modifying factor) is added to predicted levels. 

Low frequency criteria are detailed in Table 2.3.

INP. 



As indicated in the notes below condition 3, Schedule 3 of the project approval, modifying 

factors from Section 4 of the INP should be implemented where applicable. Tonality and low 

frequency from Mangoola Coal were assessed by analysis of the measured L Aeq spectrum. 

Years of monitoring have indicated that noise levels from mining operations, particularly 

those levels measured at significant distances from the source are relatively continuous. 

Given this, noise levels from Mangoola Coal at the monitoring locations are unlikely to be 

intermittent. In addition, there is no equipment on site at Mangoola Coal that would generate 

impulsive noise as defined in the INP. However, low frequency noise from Mangoola Coal 

has been addressed. 


However, if site noise is noted as

Notes: 1. Wind speed and sigma theta data sourced from Mangoola Coal meteorological stations. Data from the nearest 

met station to the monitoring location was used. Sigma theta data used to calculate Vertical Temperature 

Gradient (VTG) in accordance with procedures detailed in the INP; 

2. Noise emission limits apply for the following meteorological conditions: 

• 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 2m/s at 10 metres above 

ground level; 

3. Y denotes Yes, N denotes No; 

4. These are results for Mangoola Coal in the absence of all other noise sources; 

5. NM denotes audible but not measurable, IA denotes inaudible; 

6. Bolded results in red are those greater than the relevant criterion (if applicable); and 

7. NA in exceedance column means atmospheric conditions outside conditions specified in project approval and so 

criterion is not applicable.

Insects were primarily responsible for the measured levels. Road traffic engine noise and a 

train contributed to the measured L A1, L A10 and L Aeq. 

Frogs, ducks, dogs, a rural continuum, road traffic tyre noise, a train horn, cows and breeze in 

foliage were also noted.

An engine continuum and rear dump truck exhaust and engine noise from Mangoola Coal 

was audible during the measurement. Impact noise and track noise was also audible. These 

sources resulted in a Mangoola Coal only L Aeq of 30 dB. Impact noise generated the 

Mangoola Coal only L A1,1min of 40 dB. 

Insects generated the measured levels. 

Frogs, bats and dogs were also noted.

period of 4 July, the evening of 11 July and night periods of 5/6 July and 11 July 2012. Night 

monitoring was completed over two separate visits as rain occurred on the first night. 

As shown in Section 4 of this report, Mangoola Coal complied with the relevant day, evening 




and where meteorological conditions resulted in criteria applying (in accordance with the 

project approval). A post analysis of these three results was carried out for low frequency 

content. 

The low frequency assessment carried out in accordance with the INP and Broner methods 

identified exceedances of both low frequency criteria at Roxburgh Road (A5) during the night 

period of 11 July 2012. A 5 dB penalty was applied to the measured result from this location 

in accordance with the INP method. The penalty resulted Mangoola Coal noise levels being 

equal to the project approval and EPL impact assessment criteria at Roxburgh Road (A5).

A continuum from Mangoola Coal was audible throughout the measurement. Track noise, 

impact noises and engine surges were also audible. These sources resulted in a Mangoola 

Coal only L Aeq of 35 dB. Engine surge generated the Mangoola Coal only L A1,1min of 42 dB. 


Road traffic tyre noise, insects, bats and dogs were also noted.

Continuum from Mangoola Coal was audible throughout the measurement. Track noise, 

impact noise, transmission noise, reverse alarms, horns and a two toned alarm were also 

audible. These sources resulted in a Mangoola Coal only L Aeq of 25 dB. A surge in the 

continuum generated the Mangoola Coal only L A1,1min of 32 dB. 

Mangoola Coal was largely responsible for the measured levels. Dogs contributed to the 

measured L A1 . 

Frogs, birds and road traffic tyre noise were also noted.

and where meteorological conditions resulted in criteria applying (in accordance with the 

project approval). A post analysis of these three results was carried out for low frequency 

content. 

The low frequency assessment carried out in accordance with the INP and Broner methods 

identified exceedances of both low frequency criteria at Roxburgh Road (A5) during the night 

period of 11 July 2012. A 5 dB penalty was applied to the measured result from this location 

in accordance with the INP method. The penalty resulted Mangoola Coal noise levels being 

equal to the project approval and EPL impact assessment criteria at Roxburgh Road (A5).

measurement. Track noise, train loading noise, CHPP continuum and an impact noise were 

also noted. These sources resulted in a Mangoola Coal only L Aeq of 30 dB. A surge in engine 

continuum generated the Mangoola Coal only L A1,1min of 35 dB. 


Cows were also noted.

6 SUMMARY 










None the 15 measurements occurred during which Mangoola Coal was measurable and 

where meteorological conditions resulted in criteria applying (in accordance with the project 

approval). A low frequency assessment was therefore not required.

Weather Observations 

measured levels. 

Road traffic noise, breeze, dogs, an 

aircraft and a continuum in the rail 

corridor were also noted. 

Cloud cover: 0/8, Wind 

speed at 10 m: 1.2 m/s, 

VTG: -1 degrees Celsius 

per 100 m 


Insects and frogs generated the 


Breeze in foliage, breeze on the 

microphone, road traffic noise, bats, 

cows and a continuum from Sandy 

Hollow direction were also noted. 

Cloud cover: 1/8, Wind 

speed at 10 m: 3.8 m/s, 

VTG: 3 degrees Celsius 

per 100 m 

Engine continuum and rear dump 

trucks from Mangoola Coal were 

audible throughout the 

measurement. Track noise, train 

loading noise, CHPP continuum 

and an impact noise were also 

noted. These sources resulted in a 

Mangoola Coal only LAeq of 30 dB. 

A surge in engine continuum 

generated the Mangoola Coal only 


Insects and frogs generated the 


Cows were also noted.
