1 INTRODUCTION

1.1 Assessment Requirements

Helensburgh Coal Pty Ltd (HCPL) owns and operates the Metropolitan Colliery, located approximately 30 kilometres (km) north of Wollongong in New South Wales (NSW). The Metropolitan Colliery has a long history that extends back to the 1880s and longwall mining commenced at the Metropolitan Colliery in 1995. The mine currently produces approximately 1.5 million tonnes (Mt) of coking coal per year.

HCPL proposes an expansion of the Metropolitan Colliery raw coal production and upgrade of the Coal Handling and Preparation Plant (CHPP) to increase saleable coal production which is referred to as the Metropolitan Coal Project (the Project). Heggies Pty Ltd (Heggies) has been engaged by HCPL to evaluate and assess the potential noise impacts associated with the Project. The assessment has been guided by the NSW Department of Planning (DoP) Environmental Assessment Requirements (EARs) which require consideration of potential construction, operational and on-site and off-site road and rail noise and vibration impacts.

In accordance with the DoP requirements, the major sources of noise emissions may be grouped as follows:

On-site Intrusive Noise Assessment

Surface construction works would be undertaken intermittently over a period of up to five years, generally during daytime hours. Construction activity associated with the CHPP upgrade and establishment of a backfill paste plant would coincide with the end of Year 3 operations and have been assessed cumulatively with other on-site operational noise sources. Project operations in Year 15 coincide with peak coal production and have also been assessed.

The NSW Industrial Noise Policy (INP 2000) provides non-mandatory procedures for setting acceptable LAeq(15minute) intrusive (and LAeq(period)) amenity noise levels for various receiver areas and guidelines for assessing noise impacts from on-site stationary noise sources.

Cumulative Industrial Noise Amenity

The INP also provides non-mandatory cumulative noise assessment guidelines that address existing and successive industrial development by setting acceptable (and maximum) cumulative LAeq(period) amenity levels for all industrial (ie non-transport related) noise in a receiver area. Note, the INP does not set acceptable cumulative LAeq(15minute) intrusive criteria for all industrial noise sources in a receiver area, but rather seeks to control cumulative noise via its amenity criteria.

The existing Metropolitan Colliery is the only significant industrial development located to the east of the Helensburgh Township (excluding the municipal tip located to the north-east of the Metropolitan Colliery) and therefore the potential for cumulative industrial noise is minimal.

Blast Emissions

Underground Blasting: Use of explosives is not required for existing or proposed general underground coal mining. Occasionally the existing continuous miner encounters geological structures that are broken up by using very low explosive masses.

The NSW Department of Environment and Climate Change’s (DECC’s) “Assessing Vibration: A Technical Guideline” dated February 2006 does not address blast-induced effects. However, Australian Standard AS 2187.2 - 2006 “Explosive - Storage and use Part 2: Use of Explosives - Appendix J” does provide guidance on relevant procedures for assessing the blast-induced noise and vibration effects on buildings and their occupants.



(10-5055R1) 31 July 2008 Page 2

The DECC currently adopts the Australia and New Zealand Environment Council Committee (ANZECC) “Technical Basis for Guidelines to Minimise Annoyance due to Blasting Overpressure and Ground Vibration” dated September 1990 for assessing potential annoyance from blast emissions during daytime hours.

The assessment of blast emission impacts outside the hours advocated by ANZECC remains according to the “Environmental Noise Control Manual” (ENCM) (EPA, 1994) Chapter 154 Noise Control Guideline - Blasting.

Off-site Transport Noise

Road Traffic: The existing site access and coal haulage routes remain unaltered by the Project and mine generated employee and materials movement along these public roads are not increased significantly by the Project operation. Slight traffic increases are anticipated to occur during Project construction and operation and are therefore assessed in accordance with the DoP’s requirements.

The NSW “Environmental Criteria for Road Traffic Noise” (ECRTN 1999) provides non-mandatory procedures for setting acceptable LAeq noise levels on arterial, collector and local roads and guidelines for assessing noise impacts from off-site road traffic.

Rail Traffic: The Rail Corporation NSW (RailCorp) operates the South Coast rail network in NSW. Noise emissions from the railway are regulated via RailCorp’s Environment Protection Licence (EPL No 12208, review date 17 December 2012).

1.2 Current Approvals

The Metropolitan Colliery is regulated via the DECC EPL Licence No 767 (review date 9 September 2009) and associated Pollution Reduction Program (PRP) requirements. The current EPL includes PRP 12 - Stage 2 Noise Investigation and Mitigation Program (Attached as Appendix A1).

While the EPL does not nominate specific regulatory noise limits, PRP 12 nominates provisional noise criteria (noise goals) as presented in Table 1. Measured background noise levels in the absence of the Metropolitan Colliery operations are further discussed in Section 4 and project specific noise assessment criteria are presented in Table 14.

Oxley Place 45 40 40 50

Parkes Street 45 40 40 50

In accordance with the requirements of the PRP12, HCPL forwarded Heggies Report 10-5055-R3 “PRP 12 Noise Reduction Programme - Stage 2 Noise Mitigation Investigation” dated 31 March 2008 to the DECC (the PRP 12 Study). PRP 12 Study major findings include:

The Metropolitan Colliery’s existing noise emissions are well above the DECC’s PRP 12 noise goals and it is not reasonable and feasible to achieve the nominated goals in the absence of some major change such as complete replacement and relocation of the CHPP building and associated materials handling plant and equipment.

HCPL conduct a Washery Building Noise Control Engineering Feasibility Assessment and implement noise controls as identified by the assessment. HCPL investigate coal reject and product truck subcontract dates and options for variations with respect to noise emissions.



(10-5055R1) 31 July 2008 Page 3

HCPL to implement a continuous noise improvement program for the major surface facilities area including a low noise maintenance replacement and procurement policy.

HCPL to consult with DECC in relation to setting revised noise goals for the on-going operation of the Metropolitan Colliery and reasonable and feasible noise reduction targets.

HCPL revisit the above program at any time, subject to the progress and outcomes of the proposed Project.

The PRP 12 Study report was prepared independently of HCPL’s plans for the Project, however as anticipated, it is now appropriate to draw upon the PRP 12 Study major findings, which have been incorporated into this Project noise impact assessment where consistent with the EARs and the NSW INP guidelines.

2 PROJECT OVERVIEW

2.1 Overview of Project Operations

The Project general arrangement and an indication of the progressive development of the Project longwalls over the life of the Project are shown in Appendix B1. The general arrangement of the Project has been designed to maximise the utilisation of existing Metropolitan Colliery infrastructure. The major surface facilities to be upgraded or added are shown in Appendix B2. The main activities associated with development of the Project would include:

Ongoing surface and underground exploration activities in the Project underground mining area and surrounds.

Continued development of underground mining operations within existing HCPL mining and coal leases (and associated sub-leases) and two new Mining Lease Application areas (MLA 1 and MLA 2).

Upgrade of the existing mining and materials handling systems (eg longwall machinery and conveyors) to facilitate an increased run-of-mine (ROM) coal production rate (up to approximately 3.2 million tonnes per annum [Mtpa]).

Upgrade of the CHPP to facilitate increased production of washed coal (approximately 2.8 Mtpa), including the addition of a beneficiation circuit to produce a new thermal coal product.

Continued transport of coal reject to the Glenlee Washery for emplacement by Sada, with annual road movements capped at the existing maximum rate.

Continued transport of product coal by road to Coalcliff and Corrimal coking plants, with annual road movements capped at the existing maximum rate.

Construction of a coal reject paste backfill plant and associated coal reject stockpile, pumping, pipeline and underground delivery systems to facilitate the underground emplacement of coal reject materials as an integrated component of the longwall mining operation.

Train loading and train movements associated with the transport of product coal to Port Kembla 24 hours per day and seven days per week.

Surface access within the Woronora Special Area and surrounds that is required for the environmental monitoring, management and remediation of mine subsidence.

Upgrade and/or extension of the existing supporting infrastructure systems (eg underground access, water management, ventilation and electrical systems) as required.

Other associated minor infrastructure, plant, equipment and activities.

The Project would extend the life of the Metropolitan Colliery by approximately 25 years.



(10-5055R1) 31 July 2008 Page 4

2.2 Project Construction and Development Activities

Infrastructure that is required to support the Project increase in ROM coal production would be progressively developed in parallel with ongoing mining operations at the Metropolitan Colliery. The Initial Development Schedule is attached as Appendix C1 and the key components that would be developed during the initial stages of the Project include:

Longwall mining machinery and electricity supply upgrades.

Upgrade of materials handling systems (Appendix C2) from approximately 650 tonnes per hour (tph) to approximately 1000 tph.

Upgrade of the CHPP (Appendix C3) to include a beneficiation circuit (to produce thermal coal) and to facilitate increased coal washing and production from approximately 400 tph to approximately 600 tph.

An additional (short-term) 50,000 tonne ( t) stockpile for coal rejects adjacent to a new backfill paste plant (approximately 75 tph) and goaf cavity injection system to dispose of excess coal reject material.

Surface construction works would be undertaken intermittently over a period of up to five years generally during daytime hours up to seven days per week. For short periods additional mobile equipment would be required.

2.3 Current and Proposed Hours of Operation

The existing Metropolitan Colliery and proposed project operating hours are summarised in Table 2.

2.4 Receiver Areas

The nearest potentially affected residential and community receiver areas beyond the major surface facilities area boundary are shown on the Receiver Area Plan (Appendix D1). Selected representative assessment locations for each receiver area are presented in Table 3. Local Environmental Planning zones are shown on the Local Zoning Plan (Appendix D2).



(10-5055R1) 31 July 2008 Page 6

Table 3 also presents the nominated noise amenity zones based on the INP’s Chapter 2 Industrial Noise Criteria and the INP’s Application Notes (July 2006) in relation to the selection of appropriate noise amenity zones - refer to INP extracts attached as Appendix D3. The suburban noise amenity zone has been nominated for the residential dwellings near the Project boundary. However it is likely that some of the nearest dwellings to the existing Metropolitan Colliery boundary are within what is termed an urban/industrial interface noise amenity zone, as is applicable to residences adjoining existing industrial developments under the INP.

The remainder of the residential dwellings to the north and beyond the Project boundary are generally removed from the immediate and existing Metropolitan Colliery area and therefore well within the suburban noise amenity zone.

3 EXISTING METEOROLOGICAL ENVIRONMENT

3.1 Meteorological Environment

The NSW INP (2000) Section 5.3, Wind Effects, states:

“Wind effects need to be assessed where wind is a feature of the area. Wind is considered to be a feature where source to receiver wind speeds (at 10 m height) of 3 m/s or below occur for 30 percent of the time or more in any assessment period in any season.”

An assessment of prevailing wind conditions was derived from the meteorological data generated by the Commonwealth Scientific and Research Organisation’s (CSIRO’s) Air Pollution Model (TAPM) software which has been used to simulate the meteorology of the area and is particularly useful in the highly variable terrain at Helensburgh. The dominant seasonal wind speeds and directions for an annual period are presented in Appendix E2 for daytime (0700 hours to 1800 hours), evening (1800 hours to 2200 hours) and night-time (2200 hours to 0700 hours).

The prevailing winds less than (or equal to) 3 metres per second (m/s) with a frequency of occurrence greater than (or equal to) 30% and considered to be relevant to the site in accordance with the INP are presented in Table 4. The dominant conditions incorporated into noise modelling are underlined.

Table 4 Prevailing Wind Velocities in Accordance with the INP

Winds ± 45o ≤3 m/s with Frequency of Occurrence ≥30% Season

Daytime Evening1 Night-time1

Annual Nil Nil Nil

Summer Nil N, NNE N, NNW, NW

Autumn Nil Nil Nil

Winter Nil Nil Nil

Spring Nil Nil Nil

Note 1: The dominant seasonal wind velocities are underlined.

The INP Section 5.2, Temperature Inversions, states:

“Assessment of impacts is confined to the night noise assessment period (10.00 pm to 7.00 am), as this is the time likely to have the greatest impact - that is, when temperature inversions usually occur and disturbance to sleep is possible.”

“Where inversion conditions are predicted for at least 30% (or approximately two nights per week) of total night-time in winter, then inversion effects are considered to be significant and should be taken into account in the noise assessment”.

An assessment of atmospheric stability conditions has also been prepared from the meteorological data set described above. The winter evening and night-time frequency of occurrence of atmospheric stability classes are presented in Table 5, together with estimated Environmental Lapse Rates (ELR).



(10-5055R1) 31 July 2008 Page 9

Table 5 Atmospheric Stability Frequency of Occurrence - Winter Evening/Night-time

Stability Class

Estimated ELR1 oC/100 m

Qualitative Description

A 0% <-1.9 Lapse

B 0% -1.9 to -1.7 Lapse

C 0% -1.7 to -1.5 Lapse

D 38% -1.5 to -0.5 Neutral

E 37% -0.5 to 1.5 Weak Inversion

F & G 26% 1.5 to >4.0 Moderate to Strong Inversion

Note 1: ELR (Environmental Lapse Rate).

In accordance with the INP, the frequency of occurrence of moderate to strong (ie 1.5 to >4.0oC/100 m) winter temperature inversions is less than 30% during the combined evening and night-time period and therefore does not require assessment.

While winter temperature inversions are not necessarily an assessable weather condition in accordance with the INP, a review of the local topography and together with the prevalence of light west to north-westerly winds is likely to produce coastal strength weak to moderate temperature inversions and associated drainage flow during winter.

3.2 Environmental Noise Model Meteorological Parameters

The noise modelling meteorological parameters presented in Table 6 are based on analysis of the TAPM meteorological data set and field measurements carried out during noise monitoring. In this case, the observed meteorological conditions at Helensburgh are generally consistent with the default parameters presented in the INP Section 5 Meteorological Conditions.

Table 6 Calm (neutral) and Noise Enhancing Meteorological Modelling Parameters

Evening Summer Wind only

15oC 80% NNE 3 m/s 0oC/100 m

Night-time Summer Wind only

15oC 80% N 3 m/s 0oC/100 m

In summary, evening and night-time north to north-easterly breezes prevail for significant periods during warmer seasons.

During the cooler seasons weak to moderate temperature inversions and associated west to north-westerly drainage flows prevail during night-time for less significant periods of time. The north-westerly drainage airflow is likely to diminish noise emissions from the existing Metropolitan Colliery and the proposed Project as residences are mostly located to the south, west and north of the site.

4 EXISTING BACKGROUND AND TRAFFIC NOISE ENVIRONMENT

The following subsections outline the results of relevant ambient and background noise monitoring conducted for this study and for the PRP 12 Study, where relevant.

4.1 Background Monitoring in the Absence of the Metropolitan Colliery 2006/2007

A background noise monitoring programme was conducted in December 2006 coinciding with the Christmas/New Year Colliery shutdown to quantify background noise levels (ie all noise sources) and to estimate industrial noise only (ie in the absence of transport, natural and domestic noise) at four representative residential locations in the vicinity of the Metropolitan Colliery.

In order to supplement the unattended logger measurements and to assist in identifying the character and duration of the noise sources, operator-attended daytime, evening, and night-time surveys were also conducted at all four logging locations. The measurement methodology and analysis procedures are described in Appendix F1. The operator-attended measurement results are summarised in Table 7.

During the monitoring period, insect noise was common and likely to be a regular seasonal feature of the noise environment. Analysis of the background noise levels in accordance with the NSW INP to derive the RBLs minimises the potential for insect noise to influence the dataset.

The following provides a brief overview of the key monitoring results:

16 Oxley Place: Moderately low (34 dBA to 36 dBA) night-time and evening background noise levels consistent with a residential area with varying exposures to local and regional transportation (ie road, rail, aircraft) noise sources, domestic noise sources and nearby bushland noise sources.

55A Parkes Street: Moderate (39 dBA to 40 dBA) night-time and evening background noise levels. It appears that the unattended RBLs at Parkes Street (P55A) were unduly influenced by insect noise. It is reasonable to extrapolate the results from Oxley Place (O16) to Parkes Street (55A) as there is comparable exposure local and regional transportation and domestic noise sources and nearby bushland flora and fauna noise sources.

83 Parkes Street: Low (30 dBA to 34 dBA) night-time and evening background noise levels consistent with a relatively confined residential area with varying exposures to local and regional transportation noise sources, domestic noise sources.

19 Old Farm Road: Low (30 dBA to 33 dBA) night-time and evening background noise levels consistent with a relatively remote residential area with varying exposures to local and regional transportation noise sources, domestic noise sources and nearby bushland flora and fauna noise sources.

Industrial Noise: Little or no continuous industrial noise contribution at all locations.

4.2 Plant Operating Noise Monitoring November 2007 and March 2008

Noise monitoring to establish existing Metropolitan Colliery noise emissions was carried out in relation to the PRP12 Study. The measurement methodology is described in Heggies Report 10-5055-R3 “PRP 12 Noise Reduction Programme - Stage 2 Noise Mitigation Investigation” dated 31 March 2008. A noise monitoring programme was conducted in November 2007 and March 2008 coinciding with normal mine operations to quantify ambient noise levels (ie all noise sources) and to estimate the noise contribution from the Metropolitan Colliery only. The key operator-attended measurement results are summarised in Table 9.

4.3 Background Noise for the Purpose of Noise Impact Assessment

The measured background and amenity levels from Section 4.1 have been distilled into single representative RBLs and industrial amenity levels for each receiver area as presented Table 11.

The background noise measurements indicate that when the Metropolitan Colliery is not operating the dwellings located near the Project Boundary are generally less protected from regional urban noise sources due to their topographic exposure and lack of shielding by other suburban buildings, and are also generally more exposed to natural bushland noise associated with the adjoining vegetated reserves.



(10-5055R1) 31 July 2008 Page 13

4.4 Ambient Traffic Noise Monitoring Inclusive of the Metropolitan Colliery March 2007

An ambient traffic noise monitoring programme was conducted in March 2007 to quantify ambient noise levels (ie all noise sources) and to estimate traffic noise only (ie total existing vehicles) at three representative residential locations along the existing off-site haulage route.

The measurement methodology and analysis procedures are described in Appendix G1. The unattended noise logger data from each monitoring location and the on-site weather conditions were analysed on a daily basis and presented graphically as statistical 24-hour ambient noise profiles in Appendix G2.

The ambient traffic noise data were then processed in accordance with the requirements of the ERTNC Policy to derive the daytime, night-time and peak hourly levels as presented in Table 12, normalised to 30m and 15m offset and facade corrected by 2.5 dBA.

4.5 Residents Noise Complaints Summary

The Metropolitan Colliery maintains a complaints register as part of its environmental management and community relations protocol. A listing of noise related complaints are presented in Appendix E1 and summarised as follows:

During 2005 and 2006, community noise concerns generally related to on-site fixed plant noise emissions (three and six noise complaints respectively).

During 2007, community noise concerns generally related off-site truck transport noise (two noise complaints).

5 NOISE ASSESSMENT CRITERIA AND METHODOLOGY

5.1 Construction Assessment Criteria

The assessment of impact from on-site construction works remains according to the EPA’s ENCM (1994) Chapter 171 Noise Control Guideline - Construction Site Noise (Appendix H). The ENCM provides noise limits for construction periods of up to 26 weeks. As the duration of the construction works is greater than 26 weeks, the EPA suggests that the construction noise emission should generally not exceed the background level by more than 5 dBA. As the Project construction activities would extend over approximately 5 years, construction noise has been assessed by incorporation in the Year 3 operational scenario (Sections 8 and 9).



(10-5055R1) 31 July 2008 Page 14

5.2 Operating Assessment Criteria - Sleep Disturbance

The INP does not specifically address sleep disturbance from high noise level events.

The EPA’s ECRTN (EPA 1999) recognised that the current sleep disturbance criterion of an LA1(1minute) not exceeding the LA90(15minute) by more than 15 dBA is not ideal. Nevertheless, as there is insufficient evidence to determine what should replace it, DECC will continue to use it as a guide to identify the likelihood of sleep disturbance. This means that where the criterion is met, sleep disturbance is not likely, but where it is not met, a more detailed analysis is required.

The DECC’s interim “Sleep Disturbance Noise Criteria Guideline” dated 22 June 2004 indicates that the LA1(1minute) level 15 dBA above the RBL is a suitable screening criteria for sleep disturbance for the night-time period. In practice, sleep disturbance is assessed as the emergence of the LA1(1minute) level above the LA90(15minute) prevailing at the time as described in the guideline and consistent with the EPA’s ECRTN Appendix B Section B5.

The INP’s more recent Application Notes (July 2006) indicate that a more detailed analysis should cover the maximum noise level or LA1(1minute), that is, the extent to which the maximum noise level exceeds the background level and the number of times this happens during the night-time period. Some guidance on possible impacts is contained in the review of research results in the appendices to the ECRTN. Other factors that may be important in assessing the extent of impacts on sleep include:

How often high noise events will occur.

Time of day (normally between 2200 hours and 0700 hours).

Whether there are times of day when there is a clear change in the noise environment (such as during early morning shoulder periods).

The LA1(1minute) descriptor is meant to represent a maximum noise level measured under “fast” time response. DECC will accept analysis based on either LA1(1minute) or LAmax. A review of noise events from the Metropolitan Colliery’s night-time operations including train movements indicates that the maximum (LAmax) levels are typically no greater than 10 dBA above the LAeq(15minute) intrusive level when measured at a distant receiver (refer Heggies Report 10-5055-R3 dated 31 March 2008).

Therefore, it is considered that the INP-based intrusive criteria would be the controlling factor in determining compliance for the Project. This relationship enables the noise assessment process to focus on the setting and impact assessment of INP-based intrusive noise and amenity levels which aim to minimise annoyance at noise sensitive receiver locations.

5.3 Operating Assessment Criteria - Intrusive Noise and Amenity Levels

The DECC has regulatory responsibility for the control of noise from “scheduled premises” (Metropolitan Colliery is a scheduled premises) under the Protection of the Environment Operations Act 1997. In implementing the INP the DECC has two broad objectives:

Controlling intrusive noise impacts in the short term.

Maintaining noise level amenity for particular land uses over the medium to long term.

The INP prescribes detailed (but non-mandatory) calculation routines for establishing “project specific” LAeq(15minute) intrusive criteria and LAeq(period) amenity (ie non-transport related) criteria for new and existing developments at potentially affected receivers.



(10-5055R1) 31 July 2008 Page 15

Ideally, the intrusive noise emission should generally not exceed the background level by more than 5 dBA. Similarly, the amenity level should generally not exceed the specified INP “acceptable” or “maximum” noise level appropriate for the particular locality and land use as shown in Table 13.

Note 2: As described in Section 2.4, some of these locations could be considered to be within an urban/industrial interface noise amenity zone.

Note3: External criteria equivalent to internal criteria plus 10 dBA.

In accordance with the INP’s Chapter 2 Industrial Noise Criteria in conjunction with the INP’s Application Notes (July 2006), the “project specific” intrusive and amenity assessment criteria for the residential, commercial and industrial receiver areas are presented in Table 14.

For the purposes of assessing noise impacts at the nearest dwellings to the Project boundary, the DECC’s PRP 12 noise goals have been adopted. These dwellings due to their locations are most exposed to the existing noise of the Metropolitan Colliery when it is operating.

As discussed in Section 2.4, the suburban noise amenity zone has been adopted for all residential dwellings, however, it is likely that some of the nearest dwellings to the existing Metropolitan Colliery boundary (as shown in Appendix D1) are within an urban/industrial interface noise amenity zone as defined under the INP.

The recommended intrusive project specific criteria for the remaining dwellings north and beyond the Project boundary are relatively lower than the criteria for the nearest dwellings during the daytime, evening and night-time periods by 3 dBA, 2 dBA and 5 dBA respectively.

The INP states that these criteria have been selected to preserve the amenity of at least 90% of the population living in the vicinity of industrial noise sources from the adverse effects of noise for at least 90% of the time. Provided the criteria in the INP are achieved, then most people would consider the resultant noise levels acceptable.

In those cases where the INP project specific assessment criteria are not achieved, it does not automatically follow that all people exposed to the noise would find the noise unacceptable. In subjective terms, exceedances of the INP project specific assessment criteria can be generally described as follows (where noise levels are predicted to increase as a result of a new development):

Negligible noise level increase <1 dBA (not noticeable by all people).

Marginal noise level increase 1 dBA to 2 dBA (not noticeable by most people).

Moderate noise level increase 3 dBA to 5 dBA (not noticeable by some people but may be noticeable by others).

Appreciable noise level increase >5 dBA (noticeable by most people).

It should be noted that the Project noise emissions are predicted to fall at most locations by comparison with the existing Metropolitan Colliery operation (refer Section 8). Therefore the above would be reversed in most cases (ie some receptors would be expected to notice 3 dBA to 5 dBA Project noise reductions, while most receptors would notice Project noise reductions of 5 dBA or more).



(10-5055R1) 31 July 2008 Page 17

5.4 Noise Impact Assessment Methodology

In view of the foregoing, Table 15 presents the methodology for assessing noise levels which may exceed the INP project specific noise assessment criteria.

For the purposes of assessing the potential noise impacts, the management and affectation criteria are further defined as follows:

Noise Management Zone

Depending on the degree of exceedance of the project specific criteria (1 dBA to 5 dBA) noise impacts could range from negligible to moderate, in cases of a new facility or increased noise levels from an existing facility. As the Metropolitan Colliery is an existing facility and Project noise emissions are predicted to decrease at most assessed receivers by comparison to the existing emissions (Section 8), community responses are expected to differ.

Notwithstanding, it is recommended that management procedures be implemented including:

Noise monitoring on site and within the community.

Prompt response to any community issues of concern.

Refinement of on-site noise mitigation measures and mine operating procedures where practical.

Noise Affectation Zone

Exposure to noise levels corresponding to this zone may be considered unacceptable by some land owners, particularly at night in cases of a new facility or increased noise levels from an existing facility. As the Metropolitan Colliery is an existing facility and Project noise emissions are predicted to decrease at most assessed receivers by comparison to the existing emissions (Section 8), community responses are expected to differ.

Notwithstanding, it is recommended that HCPL explore the following:

Discussions with relevant land owners to assess concerns and define responses.

Consideration of implementation of acoustical mitigation at receivers.

Negotiated agreements with land owners, where required.

6 PROJECT NOISE MODEL

Project noise modelling has utilised the detailed noise model developed for the Metropolitan Colliery PRP 12 Study. Where relevant to this Project noise assessment, aspects of the PRP 12 Study model preparation are outlined below.



(10-5055R1) 31 July 2008 Page 18

6.1 Metropolitan Colliery Noise Model Establishment Procedure

The Metropolitan Colliery computer model was developed for the PRP 12 Study to incorporate the significant noise sources associated with the surface facilities. Additionally, surrounding terrain, aspects of the built environment and nearby receiver areas were also included in the model.

The Metropolitan Colliery computer model was prepared using the SoundPLAN noise model utilising the CONCAWE algorithm, a commercial software system developed by Braunstein & Berndt International. The acoustical algorithms utilised by this software are endorsed national or international standards and are therefore accepted by the NSW DECC as suitable for use.

6.2 PRP 12 Fixed Plant Noise Audit - Sound Power Levels

In order to establish the Metropolitan Colliery noise model, on-site nearfield noise measurements to determine fixed plant sound power levels (SWLs) were conducted on 13 and 22 November 2007. Noise measurement procedures were guided by the requirements of AS 1217.7-1985 “Acoustics - Determination of Sound Power Levels Part 7 Survey Method” (AS 1217.7:1985) and the results summarised in Table 16.

These fixed plant SWLs have been utilised in the Project noise model, where relevant.

In order to establish the Metropolitan Colliery noise model, on-site nearfield noise measurements to determine mobile equipment SWLs were conducted on 13 and 22 November 2007. Noise measurement procedures were guided by the requirements of AS 1217.7:1985 and the results are summarised in Table 17.

6.4 PRP 12 Off-site Noise Model Calibration Procedure

Off-site noise measurements to determine Colliery noise contributions at selected calibration locations were conducted on 13, 22 November 2007 and 26 March 2008. Noise measurement procedures were guided by the requirements of AS 1055-1997 “Acoustics - Description and Measurement of Environmental Noise” as discussed in Section 4.1.

A moderate calibration adjustment of 5 dBA has been incorporated into the Metropolitan Colliery noise model and is generally consistent with field measurement and modelling results from similar materials handling and resource related industrial developments. A smaller calibration adjustment of 2 dBA has been applied to haul trucks on Colliery Road, due to the close proximity of this activity to the nearest receivers. The above model calibration has been incorporated into the Project noise modelling.



(10-5055R1) 31 July 2008 Page 21

6.5 Project Noise Model Scenarios

The three operating modelling scenarios examined for the Project include significant fixed plant and mobile equipment operating concurrently to simulate the likely intrusive emissions and noise amenity levels, namely:

Existing on-site Metropolitan Colliery Operations (for Project comparison purposes) including:

Nil construction activity.

ROM coal production (1.8 Mtpa) with CHPP 400 tph capacity and conveyor handling system at current capacity.

Coal train loading operations of coking coal (1.4 Mtpa).

Coal reject haulage off-site emplacement at Glenlee Washery.

Coking coal trucking for off-site delivery to Corrimal and Coalcliff Coke Works.

Project Year 3 Operations and Construction, including on-site:

Construction activity associated with the CHPP upgrade and establishment of the backfill paste plant.

Increased ROM coal production (2.13 Mtpa) with CHPP upgraded to 600 tph capacity and beneficiation circuit operating but conveyor handling system unchanged.

Coal train loading operations of coking coal (1.69 Mtpa) and thermal coal (0.03 Mtpa).

Coal reject haulage to on-site stockpile at a rate of 40,000 tpa together with trucking for off-site emplacement at Glenlee Washery.


Progressive implementation of noise controls.

Project Year 15 Operations, including on-site:

Increased ROM coal production (3.19 Mtpa), CHPP upgraded to 600 tph capacity, Beneficiation Circuit operating and conveyor handling systems upgraded to 1000 tph.

Coal train loading operations of coking coal (2.59 Mtpa) and thermal coal (0.05 Mtpa).

Coal reject haulage to backfill paste plant operating at a rate of 0.43 Mtpa.


Additional noise controls implemented.

Note, an average number of heavy vehicle pass-bys along Colliery Road have been included in the noise model as part of the on-site Colliery daytime noise. During peak periods the number of heavy vehicle movements could potentially be greater than the average number of pass-bys.

7 PROJECT NOISE MITIGATION MEASURES

The identification of Project noise mitigation measures and incorporation of these measures in the Project noise model (Section 6) has built on the noise mitigation investigations conducted for the PRP 12 Study and includes the noise mitigation measures currently being implemented by HCPL. Where relevant these are described below.



(10-5055R1.doc) 31 July 2008 Page 22

7.1 PRP 12 Identification of Existing Plant with the Highest Noise

As part of the PRP 12 Study, the operator-attended measurements discussed in Section 4.1, identified the existing Washery Building as the highest contributing Colliery noise source at the key dwellings located at 2 Oxley Place (O2) and 53 Parkes Street (P 53).

It was also determined that the Washery Building has the highest fixed plant SWLs of 117 dBA which is emitted over a large surface area, with several existing openings and windows particularly on the southern and western facades facing the Oxley Place and Parkes Street dwellings. There is line of sight (although heavily timbered) between the upper levels of the Washery Building and some of the nearest dwellings on Oxley Place and Parkes Street, allowing the Washery’s noise emissions to propagate freely from source to receiver.

Predictions of the noise contribution of other appreciable (although less significant by comparison with the Washery) Metropolitan Colliery noise sources was conducted via computer based noise modelling as a component of the PRP 12 Study.

The results of the fixed and mobile plant audits are provided in Sections 6.2 and 6.3.

7.2 PRP 12 Investigation of Potential Fixed Plant Noise Controls - Existing Operation

As a component of the PRP 12 Study the current fixed plant SWLs (including any existing noise controls) were compared to “technically achievable” low noise emission standards that have been demonstrated as sustainable by retrofit (rather than equipment replacement) while still reducing the noise at its source (or alternatively very near to the commencement of the noise propagation path - eg by enclosure).

Technically achievable noise control or low emission benchmarks were established by researching the results of recent CHPP and mobile fleet noise reduction programmes for other mining projects and low noise materials handling technology associated with existing and approved coal handling facilities in the Port of Newcastle.

The coarse washery building, pumps/compressor units, transfer conveyors and large conveyor drive assembly were all identified as potential noise reduction targets where the existing source noise was appreciably above the technically achievable low noise emission benchmarks. Of these, the enclosure of the coarse washery building utilising continuous span 0.47 millimetre (mm) Colorbond profile steel cladding (or equivalent) and 50 mm Rockwool sealed in a thin mylar film and perforated steel sheeting (or equivalent) was identified as the most potentially effective noise control measure by the PRP 12 Study.

7.3 PRP 12 Mobile Equipment Noise Controls and Management - Existing Operation

As a component of the PRP 12 Study, the measured mobile equipment SWLs (including any existing noise controls) were compared to comparable equipment of similar design and operation. All items of major mobile equipment surveyed emitted SWLs within the noise emission standard by comparison with equivalent equipment with no observed irregularity. Noise reductions are technically achievable by noise control retrofitting (rather than equipment replacement) however there remains some doubt in relation to the sustainability and on-going operating performance impacts of “after market” noise control packages.



(10-5055R1) 31 July 2008 Page 23

The PRP 12 Study concluded that while there remains potential to install noise control kits (ie high performance mufflers, acoustic louvres to radiator fan, engine dampening and track tensioning) to existing front-end loaders and tracked dozers, such measures were considered unwarranted particularly as noise arising from fixed plant sources were the major contributors at the nearest receivers.

It is also technically achievable that future mobile equipment (ie replacement or upgrade) be the subject of a continuous noise improvement programme as described in Section 7.6. An example, may include future replacement or upgrade (ie at the next subcontract renewal date) to the existing offsite truck haulage fleets (ie coal reject and coking coal) where the use of new and efficient articulated vehicles are demonstrated to emit up to 6 dBA lower noise emissions by comparison with the existing fleets.

7.4 Current HCPL Noise Control Initiatives - Existing Operation

In accordance with the findings of the PRP 12 Study, HCPL is currently examining the relative feasibility of a number of noise mitigation measures to reduce noise emissions from the coarse washery building. The preliminary results of this assessment and HCPL’s proposed noise mitigation measures for the coarse washery building have been included in this Project noise assessment, where relevant. A number of these measures are expected to be implemented prior to the DoP assessment of the Project Environmental Assessment and have been incorporated in the Project noise model on this basis.

7.5 Project Noise Control Measures Incorporated in the Model

The Project, if approved, would provide for a further 25 years of operation at the Metropolitan Colliery. The extended life of the operation and the various surface facilities upgrade works would provide an opportunity to introduce further practicable noise controls as a component of the Project upgrades.

HCPL would implement a range of noise controls and/or purchase replacement low noise equipment and implement a continuous noise improvement programme to reduce noise emissions at the Metropolitan Colliery. The timing of the implementation of the noise controls would be dependant on the actual progressive development of the Project and the measures would be implemented in order to facilitate compliance with relevant noise specifications.

Specific fixed plant and mobile equipment noise control measures incorporated in the model to meet specified SWL emissions and/or modelled levels at the nearest private receptors include:

Enclosure of the coarse washery building (HCPL has commenced aspects of this work).

The Project CHPP upgrade to include the installation of modern low-noise equipment where practicable, and/or additional sound insulation, or specific mitigation of key noise sources (eg drives).

Replacing existing exhaust silencers on pumps and compressors with high performance mufflers.

Relocating or enclosing the MD1 conveyor drive fan as a component of Project conveyor upgrades.

Partial enclosure or construction of a nearfield barrier to the south/west of the MD1 conveyor drive as part of Project conveyor upgrades.

Implementation of a low noise conveyor idler replacement system on surface transfer conveyors as a component of Project conveyor upgrades.

Enclosure of the new paste backfill plant to minimise noise emissions.



(10-5055R1) 31 July 2008 Page 24

Use of modern low-noise front-end loader and 30 t off-road trucks for on-site coal reject haulage (between the CHPP and the temporary coal reject stockpile or paste backfill plant).

Specific operational noise control measures incorporated in the noise model to meet specified SWL emissions and/or modelled levels at the nearest private receptors include:

Project surface construction activities to be restricted to daytime hours.

No off-site road haulage of product coal or coal reject during the evening or night-time periods (continuation of an existing Metropolitan Colliery operational noise control measure).

No haulage of coal reject between the CHPP and the temporary stockpile or between the CHPP and the backfill paste plant to be undertaken in the evening and night-time periods.

Use of broadband noise alarms on existing and future equipment adjusted to meet occupational health and safety (OHS) requirements.

The above measures would be implemented progressively eg conveyor upgrade and mitigation would not occur until after Year 3 (refer Initial Development Schedule). For the purposes of noise impact assessment, the design maximum LAeq SWLs are presented in Table 18 for the all acoustically-relevant items of plant and equipment for the Project (once upgraded).

8 INTRUSIVE NOISE IMPACT ASSESSMENT

The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential receptors and other suburban landuses. The Project upgrades to the major surface facilities area would not significantly change the location, nature or the main characteristics of the Metropolitan Colliery on-site noise emissions. Therefore, for comparative purposes, modelled intrusive noise predictions for the Project (Year 3 and Year 15) have been compared to modelled intrusive noise emissions for the existing Metropolitan Colliery in the subsections below for the daytime, evening and night-time periods with the application of significant weather conditions in accordance with the INP.

8.1 Daytime Existing Metropolitan Colliery and Project Year 3 and 15

The predicted daytime intrusive noise from the existing Metropolitan Colliery and proposed Project Year 3 and Year 15 operations from all on-site activities including all fixed plant and support mobile equipment and train loading are presented in Table 19. Table 19 incorporates examination of the contribution of on-site road haulage of coal or coal reject on Colliery Road to noise levels at receptors (ie model predictions have been generated with and without this equipment operating).

Existing Metropolitan Colliery Noise

During daytime with Colliery Road coal haulage (ie trucks operating) the existing Metropolitan Colliery noise levels at the nearest receivers are up to 12 dBA (O14, O16) above the criteria. In the absence of coal haulage (ie trucks not operating) the existing noise levels are up to 9 dBA (O2 and O4) above the criteria.

Predicted Project Noise

Following the implementation of potential noise controls (Section 7) the Project Year 3 and 15 noise levels are predicted to reduce at all assessed receivers to the west and south of the site. Project noise levels at receivers near the Project boundary to the north are generally predicted to remain unchanged due to the inclusion of train loading activities in the model, which are in close proximity and dominate noise emissions at these locations.

8.2 Evening Existing Metropolitan Colliery and Project Year 3 and 15

The predicted evening intrusive noise from the existing Metropolitan Colliery and proposed Project Year 3 and Year 15 operations from all on-site activities including all fixed plant, support mobile equipment, and train loading are presented in Table 20. No coal or coal reject road haulage is to be undertaken in the evening.

Existing evening Colliery noise levels are lower in the absence of coal and coal reject haulage, however the existing noise levels at the nearest receivers are up to 16 dBA (O4) above the evening criteria.


Following the implementation of Project noise controls (Section 7) the Project Year 3 and 15 noise emissions are predicted to reduce at all assessed receivers to the west and south of the site.

Existing night-time Colliery noise levels are lower in the absence of coal or coal reject haulage, however the existing noise levels at the nearest receivers are up to 16 dBA (O4) above the night-time criteria.


Following the implementation of Project noise controls (Section 7) the Project Year 3 and 15 noise emissions are predicted to reduce at all assessed receivers to the west and south of the site. Project noise levels at receivers near the Project boundary to the north are generally predicted to remain unchanged due to the inclusion of train loading activities in the model, which are in close proximity and dominate noise emissions at these locations.

The Year 3 night-time LAeq(15minute) intrusive noise contours during calm weather is presented as Appendix I. The Year 3 night-time LAeq(15minute) intrusive noise contours during 3 m/s north wind is presented as Appendix J. The calculation of the noise contours involves numerical interpolation of a noise level array with a graphical accuracy of up to approximately ±2 dBA. This means that in some cases the contour locations presented in Appendices I and J will differ from the tabulated data which have highest accuracy.

8.4 Project Year 3 and 15 - Ventilation Shaft Noise

As shown on the General Arrangement Plan (Appendix B1) the existing Ventilation Shaft No 3 is located adjacent to the F6 Southern Freeway. An additional Ventilation Shaft (No 4) is required by the Project and would be also be located adjacent to the F6 Southern Freeway and approximately 3 km north of Ventilation Shaft No 3.

The nearest residential receivers are located more than 1 km to the east of the proposed Ventilation Shaft No 4, where the night-time noise contribution is calculated to be <35 dBA based on an installed SWL of 105 dBA for the fan house and ventilation fan inclusive. The Garrawarra Centre is an aged care nursing facility which is located over 800 m to the north-west of the proposed installation and compliance with applicable amenity criteria (50 dBA external) is also predicted at this facility.

9 NOISE AMENITY IMPACT ASSESSMENT

The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential receptors and other suburban landuses. The project upgrades to the major surface facilities area would not significantly change the location, nature or the main characteristics of the Metropolitan Colliery on-site noise emissions. Therefore, for comparative purposes, modelled amenity period noise predictions for the Project (Year 3 and Year 15) have been compared to modelled noise amenity levels for the existing Metropolitan Colliery in the subsections below for the daytime, evening and night-time periods with the application of significant weather conditions in accordance with the INP.

9.1 Daytime Existing Metropolitan Colliery and Project Year 3 and 15

The predicted daytime noise amenity levels from the existing Metropolitan Colliery and proposed Project Year 3 and Year 15 operations from all on-site activities including all fixed plant and support mobile equipment, train loading are presented in Table 22. Table 22 incorporates examination of the contribution of on-site road haulage of coal or coal reject on Colliery Road to noise levels at receptors (ie model predictions have been generated with and without this equipment operating).

During the daytime the existing Metropolitan Colliery amenity noise levels near the Project boundary are below the acceptable 55 dBA criterion.


Following the implementation of Project noise controls (Section 7) the Project Year 3 and 15 noise amenity levels reduce at all assessed receivers, except locations near the Project boundary to the north which generally remain unchanged due train loading activities. Continued compliance with the amenity criteria is predicted.

During the night-time the existing Metropolitan Colliery noise amenity levels near the Project boundary are up to 13 dBA above the criterion. As discussed in Section 2.4, it is likely that some of these dwellings are within the urban/industrial interface noise amenity zone (where the acceptable criterion is 50 dBA).


Following the implementation of Project noise controls (Section 7) the Project Year 3 and 15 noise emissions are predicted to reduce at all assessed receivers except those near the Project boundary to the north where train loading noise continues to dominate.

10 BLAST EMISSIONS IMPACT ASSESSMENT

10.1 Human Comfort and Damage Criteria

Appendix J of AS 2187: Part 2-2006 “Explosives - Storage and Use - Part 2: Use of Explosives” provides detailed guidance in assessing blast induced ground (and structural) vibration and airblast effects on buildings and their occupants.

Recommended vibration limits are generally based on international standards (or studies) as presented in Appendix J Tables J4.5(A) and J4.5(B), for human comfort and structural damage respectively. Similarly, recommended human comfort and structural damage airblast limits are presented in Appendix J Tables J5.4(A) and J5.4(B) respectively.

However, ground vibration and airblast levels which cause human discomfort are generally lower than the recommended structural damage limits. Therefore compliance with the lowest applicable human comfort criteria ensures that the potential to cause structural damage is minimal.

Hence, the DECC continues to adopt the ANZECC “Technical Basis for Guidelines to Minimise Annoyance due to Blasting Overpressure and Ground Vibration” dated September 1990 for assessing potential annoyance from blast emissions during daytime hours, as follows:

The recommended maximum level for airblast is 115 dB Linear.

The level of 115 dB Linear may be exceeded on up to 5% of the total number of blasts over a period of 12 months. The level should not exceed 120 dB Linear at any time.

The recommended maximum for ground vibration is 5 millimetres per second (mm/s), Peak Vector Sum vibration velocity (PVS). It is recommended however, that 2 mm/s (PVS) be considered as the long-term regulatory goal for the control of ground vibration.

The PVS level of 5 mm/s may be exceeded on up to 5% of the total number of blasts over a period of 12 months. The level should not exceed 10 mm/s at any time.

Blasting should generally only be permitted during the hours of 0900 hours to 1700 hours Monday to Saturday. Blasting should not take place on Sundays and public holidays.

Blasting should generally take place no more than once per day.

The assessment of blast emission impacts outside the hours advocated by the ANZECC remains according to the ENCM Chapter 154 Noise Control Guidelines - Blasting presented in Table 25. Note, the suggested time of blasting in Table 25 has been modified to be consistent with the ANZECC guidelines.

10.2 Excavation Blast Design and Prediction Methodology

As discussed in Section 1.1, use of explosives is not required for general underground coal mining. Occasionally the continuous miner encounters geological structures that are broken up by using very low explosive masses. An assessment of the potential vibration and airblast emissions arising from the underground excavation blasting has been based on the typical blast design parameters presented in Table 26.

Table 26 Typical Underground Excavation Blast Design Parameters

Blast Design Parameter Typical Dimension

Pull 3 m

Holes per Delay 5 holes

Hole Diameter 38 mm

Explosive Type (Mass) Powergell (1 kilogram per metre [kg/m])

Total Explosive Mass 50 kilograms (kg)

Maximum Instantaneous Charge (MIC) 10 kg

Powder Factor 0.80 kilogram per cubic metre (kg/m3)

By adopting the anticipated excavation blast design parameters, the vibration and airblast emissions can be predicted using the relevant vibration and airblast formula presented in AS 2187.2-2006. Airblast emission arising from underground blasting would propagate from the excavation site and release to the surface via the nearest ventilation shafts. But before reaching the surface, airblast noise is attenuated due to underground confinement and a conservative 25 dB loss has been assumed for this assessment.

The relevant formulae are as follows:

PVS = 3,272 (R/Q1/2)-1.60 dBLpk = 148.4 - 24(log10R - log10Q)

where,

PVS = mm/s dBLpk = Peak airblast dBLinear inclusive of 25 dB attenuation due to underground

confinement R = Distance between charge and receiver (m) Q = Charge mass per delay (kg)

10.3 Underground Excavation Blast Emissions Prediction

The standard formulae have been used to predict vibration and airblast emissions as presented in Table 27.



(10-5055R1) 31 July 2008 Page 39

Table 27 Predicted Distance Required to Achieve Blast Emission Criteria

Period Airblast Distance Vibration Distance

Daytime 115 dBLpk 155 m 5 mm/s 180 m

Evening 105 dBLpk 140 m 2 mm/s 320 m

Night-time 95 dBLpk 360 m 1 m/s 500 m

Based on the foregoing, airblast emissions arising from underground excavation blasting are predicted to meet the most stringent night-time criteria of 95 dBLpk at a distance of 360 m from the nearest ventilation shaft. As there are no residential dwellings located within 360 m from the proposed Ventilation Shaft No 4, airblast noise impacts are likely to be minimal (which is consistent with the with existing Metropolitan Colliery excavation blasting practices).

Similarly, ground vibration levels are predicted to meet the most stringent night-time criteria of 1 mm/s at a distance of 500 m from the blast site. As all excavation blasting is conducted at least 400 m below the surface, vibration impacts are also likely to be minimal (which is also consistent with the existing Metropolitan Colliery excavation blasting practices and experience).

11 OFF-SITE TRANSPORT

11.1 Road Transport

Traffic Noise Criteria

Based on the ECRTN dated May 1999, Lawrence Hargrave Drive is classified as a “sub-arterial road” and Parkes Street as a “collector”, road. The applicable noise criteria are presented in Table 28.

The traffic noise monitoring was conducted to establish the existing traffic noise environment inclusive of the existing Metropolitan Colliery operations and summarised in Section 4.4. The existing total traffic noise levels generally already exceed the relevant criteria at nominal off-set distance of 30 m from Lawrence Hargrave Drive and 15 m from Parkes Street, Helensburgh.

Note that in all cases where the nominated criteria are already exceeded, traffic associated with new development should not be permitted to lead to an increase in the existing noise traffic levels of more than 2 dBA. This can be achieved when the Project related percentage increase in existing light and heavy vehicle movements is no greater than 60%.

Traffic Noise Impact - Lawrence Hargrave Drive

For the purposes of noise impact assessment, the existing traffic and additional Project construction and operation daily traffic flows together with the morning and afternoon peak hour flows are presented in Table 30. The percentage increase arising from the Project contributed traffic is shown in brackets.

The maximum increase arising from the additional Project related traffic flow is only 0.4% during the construction and operation morning peak hour. The anticipated 0.4% increase in vehicle movements corresponds to a negligible (<0.1 dB) increase in the existing traffic noise levels and therefore any Project related traffic noise impacts are likely to be acceptable.

The maximum increase arising from the additional Project related traffic flow is only 1.9% during construction and operation morning peak hour. The anticipated 1.9% increase in vehicle movements corresponds to a negligible (0.1 dB) increase in the existing traffic noise levels and therefore any Project related traffic noise impacts are likely to be acceptable.

11.2 Rail Transport

Railway Noise Criteria

RailCorp operates the South Coast rail network in NSW. Noise emissions from the railway are regulated via the RailCorp’s EPL No. 12208. The intent of the relevant EPL conditions is to control airborne noise by two principal means:

Noise Limits.

Management of noise via PRPs.

EPL Section L6 Noise Limits (note) provides railway operating noise objectives as follows:

It is an objective of this licence to progressively reduce noise levels to the goals of 60 dB(A)Leq, (24 hr) and 85 dB(A) max pass by noise, at one metre from the facade of the nearest affected residential property through the implementation of the Pollution Reduction Programs.

In the development of new works, the licensee is required to work towards the planning goals of 55 dB(A) Leq, (24 hr) and 80 dB(A) max pass by noise, at one metre from the facade of the nearest affected residential property.

The goals do not represent unobtrusive noise levels. Rather, the objectives recognise that rail operations are inherently noisy and represent a compromise between what may be desirable from a community point of view (ie maintaining amenity) and what is necessary to enable trains to operate.

Rail Traffic Movements

The midweek daily existing, additional and cumulative train movements are presented in Table 32 with the percentage increase arising from the Project additional traffic shown in brackets.

Railway Noise Impact

The calculation of the daily (24 hour) equivalent continuous noise levels and the maximum passby levels have been conducted using a computer prediction model developed by Heggies. This model has previously been accepted by the DoP and DECC.

The prediction model uses characteristic noise levels for the various sources (locomotive engine and exhaust noise as a function of throttle notch, wheel/rail noise as a function of train speed, and wagon type, etc) at a fixed reference distance. The model then makes adjustments for the train length and distance from the track (assuming no barriers) and facade reflection. Parameters including the daily LAeq(24hour) and maximum passby level (LAmax) can then be determined by summing the effects of the individual noise sources and by incorporating the number of train events.

The midweek daily LAeq(24hour) and maximum (LAmax) noise levels for the existing and cumulative train movements are presented in Table 34.

A comparison of the existing (average and peak LAeq(24hour)) train levels with the future cumulative train noise indicates negligible noise increase (ie <1 dBA) as there is only a small number of additional train movements arising from the Project. The 24 hour 60 dBA criterion is generally achieved at distances greater than 200 m. As is the case for the existing train levels, the maximum (LAmax) noise criterion of 85 dBA is generally achieved at distances greater than 90 m from the rail line.

11.3 Road and Rail Transport Vibration

Road and Rail Vibration Assessment Criteria

German Standard DIN 4150-3 1999 “Structural Vibration Part 3: Effects of Vibration on Structures” provides guideline criteria for evaluating the short-term and long-term effects of vibration on structures. In addition, the NSW DECC has released “Assessing Vibration: A Technical Guideline” dated February 2006 which provides guideline building vibration levels associated with a low probability of annoyance to occupants arising from continuous and impulsive vibration sources.

The range of applicable damage and annoyance risk criteria are provided in Appendix K and are summarised in Table 36.

Note 1: Conservatively assumed to be long-term for the purposes of damage risk assessment. Note 2: e.g. hospital operating theatres, precision laboratories etc. Note 3: Night-time criterion applicable only to residential dwellings.

Predicted Truck Vibration Levels

The vibration levels arising from rubber-tyred on-road haul trucks (e.g. that haul product coal and coal reject off-site) can be predicted based on the “Generalized Ground Surface Vibration Curves” presented in the “Transit Noise and Vibration Impact Assessment” dated April 1995 prepared for the US Department of Transportation. The Project truck transport of coal and coal reject would be restricted to daytime hours and the predicted peak component vibration velocities are presented in Table 37 together with the relevant criteria for residential dwellings and their occupants.

Table 37 Predicted Truck Generated Peak Component Vibration Levels

Truck Passby Speed Vibration Criteria Structure/Dwelling Near Point Distance 80 km/hr 60 km/hr 40 km/hr Damage Annoyance

3.8 m 0.8 mm/s 0.6 mm/s 0.4 mm/s

7.5 m 0.5 mm/s 0.4 mm/s 0.2 mm/s

Residential

30 m 0.1 mm/s 0.1 mm/s 0.1 mm/s

5 mm/s 0.5 mm/s

It is anticipated that trucks travelling at a speed of 40 km/hr (or less) would generate vibration levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 3.8 m (or greater).

Similarly, it is anticipated that trucks travelling at a speed of 80 km/hr (or less) would generate vibration levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 7.5 m (or greater).

The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by truck movements on the public road network at the nearest residential dwellings.

Predicted Train Vibration Levels

Similarly, the vibration levels arising from locomotive powered freight trains can be predicted based on the foregoing reference document. Project train movements would be 24 hours per day and the predicted peak component vibration velocities are presented in Table 38 together with the relevant risk criteria for residential dwellings and their occupants.

Note 1: Night-time criterion applicable only to residential dwellings.

It is anticipated that trains travelling at a speed of 40 km/hr (or less) would generate vibration levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a distances of 60 m (or greater).

Similarly, it is anticipated that trains travelling at a speed of 80 km/hr (or less) would generate vibration levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a distances of 90 m (or greater).

The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by train movements on the South Coast rail network at the nearest residential dwellings.

Offsite Road and Rail Vibration Impact Assessment

The above predictions of potential off-site rail and road vibration impacts are based on the upper range of measurement results under general standards and conditions. Where road surfaces or rail facilities are poorly maintained, additional vibration effects may result (eg if potholes occur in the road surface or rail corrugations occur on the track surface).

As the Project would not result in significant increases in the total number of heavy vehicle movements on the public road network (Section 11.1) or total rail movements on the South Coast rail network (Section 11.2), the existing vibration effects of heavy vehicle movements on the public road network and vibration effects of trains on the rail network would be generally unchanged by the Project.

12 SUMMARY OF FINDINGS

12.1 Construction Noise

As the duration of the Project construction activities would extend over approximately 5 years, construction noise has been incorporated in the Year 3 operational scenario. Modelled 3 construction activities are considered representative of likely cumulative construction and operational noise.

12.2 Operating Noise Assessment Procedure

In accordance with the INP’s Chapter 2 Industrial Noise Criteria in conjunction with the INP’s Application Notes (July 2006), the “project specific” intrusive and amenity assessment criteria for the residential, commercial and industrial receiver areas are presented in Table 39.

For the purposes of assessing noise impacts at the nearest dwellings to the Project boundary, the DECC’s PRP 12 noise goals have been adopted. These dwellings due to their locations are most exposed to the existing noise of the Metropolitan Colliery when it is operating.



(10-5055R1) 31 July 2008 Page 46

As discussed in Section 2.4, the suburban noise amenity zone has been adopted for all residential dwellings, however, it is likely that some of the nearest dwellings to the existing Metropolitan Colliery boundary are within an urban/industrial interface noise amenity zone as defined under the INP.

Assessed intrusive project specific criteria for the remaining dwellings beyond the Project boundary are relatively lower during the daytime, evening and night-time periods by 3 dBA, 2 dBA and 5 dBA respectively.

The INP states that these criteria have been selected to preserve the amenity of at least 90% of the population living in the vicinity of industrial noise sources from the adverse effects of noise for at least 90% of the time. Provided the criteria in the INP are achieved, then most people would consider the resultant noise levels acceptable.

In those cases where the INP project specific assessment criteria are not achieved, it does not automatically follow that all people exposed to the noise would find the noise unacceptable. In subjective terms, exceedances of the INP project specific assessment criteria can be generally described as follows (where noise levels are predicted to increase as a result of a new development):



(10-5055R1) 31 July 2008 Page 47

Negligible noise level increase <1 dBA (Not noticeable by all people).

Marginal noise level increase 1 dBA to 2 dBA (Not noticeable by most people).

Moderate noise level increase 3 dBA to 5 dBA (Not noticeable by some people but may be noticeable by others).

Appreciable noise level increase >5 dBA (Noticeable by most people).

It should be noted that the Project noise emissions are predicted to fall at most assessed receivers by comparison with the existing Metropolitan Colliery operation (refer Section 8). Therefore the above would be reversed in most cases (ie some receptors would be expected to notice 3 dBA to 5 dBA Project noise reductions, while most receptors would notice Project noise reductions of 5 dBA or more.

12.3 Project Noise Modelling and Mitigation Measures

The Metropolitan Colliery computer model was developed for the PRP 12 Study to incorporate the significant noise sources associated with the surface facilities. Additionally, surrounding terrain, aspects of the built environment and nearby receiver areas were also included.

The three operating modelling scenarios examined for the Project include significant fixed plant and mobile equipment operating concurrently to simulate the likely intrusive emissions and noise amenity levels, namely:

Existing Metropolitan Colliery Operations (for Project comparison) - daytime, evening and night-time.

Year 3 Operations and Construction - daytime, evening and night-time.

Year 15 Operations - daytime, evening and night-time.

A number of significant specific fixed plant and mobile equipment noise control measures have been progressively incorporated in the model to meet specified SWL emissions and/or modelled levels at the nearest private receptors, including:

Enclosure of the coarse washery building (HCPL has commenced aspects of this work).

The Project CHPP upgrade to include the installation of modern low-noise equipment where practicable, and/or additional sound insulation, or specific mitigation of key noise sources (eg drives).

Replacing existing exhaust silencers on pumps and compressors with high performance mufflers.

Relocating or enclosing the MD 1 conveyor drive fan as a component of Project conveyor upgrades.

Partial enclosure or construction of a nearfield barrier to the south/west of MD 1 conveyor drive as part of Project conveyor upgrades.

Implementation of a low noise conveyor idler replacement system on surface transfer conveyors as a component of Project conveyor upgrades.

Enclosure of the new paste backfill plant to minimise noise emissions.

Use of modern low-noise 30 t off-road trucks and front-end loader for on-site coal reject haulage (between the CHPP and the temporary coal reject stockpile or paste backfill plant).



(10-5055R1) 31 July 2008 Page 48

Specific operational noise control measures incorporated in the noise model to meet specified SWL emissions and/or modelled levels at the nearest private receptors include:

Project surface construction activities to be restricted to daytime hours.

No off-site road haulage of product coal or coal reject during the evening or night-time periods (continuation of an existing Metropolitan Colliery operational noise control measure).

No haulage of coal reject between the CHPP and the temporary stockpile or between the CHPP and the backfill paste plant to be undertaken in the evening and night-time periods.

Use of broadband noise alarms on existing and future equipment adjusted to meet OHS requirements.

The above measures would be implemented progressively eg conveyor upgrade and mitigation would not occur until after Year 3 (refer Initial Development Schedule). For the purposes of noise impact assessment, the design maximum LAeq SWLs are presented in Table 40 for all acoustically-relevant items of plant and equipment for the Project (once upgraded).

The Project, if approved, would provide for a further 25 years of operation of the Metropolitan Colliery. The extended life of the operation and the various surface facilities upgrade works would provide an opportunity to introduce further practicable noise controls as a component of the Project upgrades.



(10-5055R1) 31 July 2008 Page 49

HCPL would implement a range of noise controls and/or purchase replacement low noise equipment and implement a continuous noise improvement programme to reduce noise emissions at the Metropolitan Colliery. The timing of the implementation of the noise controls would be dependant on the actual progressive development of the Project and the measures would be implemented in order to facilitate compliance with relevant noise specifications.

12.4 Intrusive Noise Impact Assessment

The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential receptors and other suburban landuses (refer Appendix D1). The Project upgrades to the major surface facilities area would not significantly change the location, nature or the main characteristics of the Metropolitan Colliery on-site noise emissions.

Therefore, for comparative purposes, modelled intrusive noise predictions for the Project (Year 3 and Year 15) have been compared to modelled intrusive noise emissions for the existing Metropolitan Colliery for the daytime, evening and night-time periods as detailed in Section 8.

Following the implementation of reasonable and feasible noise controls the Project Year 3 and 15 noise levels reduce at all assessed receivers to the west and south of the site by significant margins (ie 10 dBA or more) at several of the nearest dwellings in Oxley Place and Parkes Street. Project noise levels at receivers near the Project boundary to the north are generally predicted to remain unchanged due to the inclusion of train loading activities in the model, which are in close proximity and dominate noise emissions at these locations.

While quite significant noise reductions (by comparison with the existing Metropolitan Colliery) are predicted through the implementation of the Project noise controls, Project noise emissions would remain above the relevant intrusive noise assessment criteria at some of the nearest dwellings near the Project boundary.

A summary of the number of privately owned dwellings where the project specific intrusive criteria are exceeded is presented in Table 41 for the daytime, evening and night-time periods.

As shown in Table 41, the number of private residences in the Metropolitan Colliery noise affectation zone (ie >5 dBA above intrusive criteria) during the daytime, evening and night-time period (15, 29 and 25 residences respectively) would be reduced significantly by the implementation of the Project. The total number of residences in the noise affection zone (all periods) for the existing operation (29) is predicted to be moderately reduced by Year 3 (to 20 residences) and be significantly reduced by Year 15 (to 14 residences).



(10-5055R1) 31 July 2008 Page 50

12.5 Noise Amenity Impact Assessment

As for the intrusive noise assessment, modelled amenity period noise predictions for the Project (Year 3 and Year 15) have been compared to modelled noise amenity levels for the existing Metropolitan Colliery for the daytime, evening and night-time periods as detailed in Section 9.

Similarly, following the implementation of reasonable and feasible noise controls, the Project Year 3 and 15 noise levels reduce at all assessed receivers to the west and south of the site and some by significant margins (ie 10 dBA or more). Project noise levels at receivers to the north are generally predicted to remain unchanged due to the inclusion of train loading activities in the model, which are in close proximity and dominate noise emissions at these locations.

While significant noise reductions are achievable through the implementation of potential noise controls, Project noise emissions would remain above the suburban noise amenity criteria at some of the nearest dwellings near the Project boundary. However, as discussed in Section 12.2, it is likely that some of the nearest dwellings to the Metropolitan Colliery boundary are within the urban/industrial interface noise amenity zone (where the relevant criteria are 10 dBA higher by comparison).

A summary of the number of privately owned dwellings where the suburban noise amenity criteria is exceeded is presented in Table 42 for the daytime, evening and night-time periods.

Night-time 8 5 5 10 12 10 14 3 -

Total Residences in Noise Affectation Zone - All Periods 14 3 -

As shown in Table 42, the number of private residences in the Metropolitan Colliery noise affectation zone (ie >5dBA above acceptable amenity criteria) during the evening and night-time periods (3 and 14 residences respectively) would be reduced significantly by the implementation of the Project. The total number of residences in the noise affection zone (all periods) for the existing operation (14), is predicted to be reduced to 3 during Year 3 and no exceedances of the acceptable amenity criteria are predicted for Year 15.

12.6 Blast Emission Impact Assessment

Use of explosives is not required for existing or proposed general underground coal mining. Occasionally the existing continuous miner encounters geological structures that are broken up by using very low explosive masses. Airblast emission arising from underground blasting would propagate from the excavation site and release to the surface via the nearest ventilation shafts. But before reaching the surface, airblast noise is attenuated due to underground confinement.

Airblast emissions arising from underground excavation blasting are predicted to meet the most stringent night-time criteria of 95 dBLpk at a distance of 360 m from the nearest ventilation shaft. As there are no residential dwellings located within 360 m from the proposed Ventilation Shaft No 4, airblast noise impacts are likely to be minimal (which is consistent with the existing Metropolitan Colliery excavation blasting practices).



(10-5055R1) 31 July 2008 Page 51

Similarly, ground vibration levels are predicted to meet the most stringent night-time criteria of 1 mm/s at a distance of 500 m from the blast site. As all excavation blasting is conducted at least 400 m below the surface, vibration impacts are likely to be minimal (which is also consistent with the existing Metropolitan Colliery excavation blasting practices and experience).

12.7 Road Traffic Noise Impact Assessment

The existing site access and coal haulage routes remain unaltered by the Project and mine generated employee and materials traffic along these public roads are not increased significantly by the Project. Any Project related traffic noise impacts are therefore likely to be acceptable.

On Lawrence Hargrave Drive, the maximum increase arising from the additional Project related traffic flow is only 0.4% during the construction and operation morning peak hour. The anticipated 0.4% increase in vehicle movements corresponds to a negligible (<0.1 dB) increase in the existing traffic noise levels.

Similarly, on Parkes Street, the maximum increase arising from the additional Project related traffic flow is only 1.9% during the construction and operation morning peak hour. The anticipated 1.9% increase in vehicle movements corresponds to a negligible (0.1 dB) increase in the existing traffic noise levels.

12.8 Rail Traffic Noise Impact Assessment

RailCorp operates the South Coast rail network in NSW. Noise emissions from the railway are regulated via the RailCorp’s EPL No 12208. EPL Section L6 Noise Limits (note) provides railway operating noise goals of 60 dB(A)Leq, (24hr) and 85 dB(A) maximum pass by noise, at one metre from the facade of the nearest affected residential property. We understand RailCorp are to achieve the noise objectives via the progressive implementation of PRPs.

The midweek and weekend (average and peak) existing, additional and cumulative train movements and associated rail noise levels have been determined for the South Coast line between Helensburgh and Otford in the vicinity of the Project site.

A comparison of the existing (average and peak LAeq(24hour)) train levels with the future cumulative train noise indicates negligible noise increase (ie <1 dBA) as there is only a small number of additional train movements arising from the Project. The daily 60 dBA criterion is generally achieved at distances greater than 200 m. As is the case for the existing train levels, the maximum (LAmax) noise criterion of 85 dBA is generally achieved by train passbys at distances greater than 90 m.

12.9 Road and Rail Transport Vibration

Road and rail vibration effects of the movement of heavy vehicles on the public road network and coal trains on the South Coast rail network have been determined.

Trucks travelling at a speed of 40 km/hr (or less) would generate vibration levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 3.8 m (or greater). Similarly, trucks travelling at a speed of 80 km/hr (or less) would generate vibration levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 7.5 m (or greater). The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by truck movements on the public road network at the nearest residential dwellings.

Trains travelling at a speed of 40 km/hr (or less) would generate vibration levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a distances of 60 m (or greater). Similarly, trains travelling at a speed of 80 km/hr (or less) would generate vibration levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a distances of 90 m (or



(10-5055R1) 31 July 2008 Page 52

greater). The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by train movements on the South Coast rail network at the nearest residential dwellings.

As the Project would not result in significant increases in the total number of heavy vehicle movements on the public road network or total rail movements on the South Coast rail network, the existing road vibration effects of heavy vehicle movements on the public road network and rail vibration effects of trains on the South Coast rail network would be generally unchanged by the Project.

12.10 Conclusion

In summary, the Project noise impact assessment indicates:

The existing major surface facilities of the Metropolitan Colliery are a significant source of existing industrial noise. The Metropolitan Colliery has been operating in this location for well over 100 years and is located in close proximity to suburban areas in Helensburgh.

The Project, in extending the life of the Metropolitan Colliery by approximately 25 years, provides an opportunity to improve noise performance by incorporating noise management improvements in the CHPP and other major surface facilities upgrades. HCPL has committed to include a range of noise reduction and operational noise controls in the Project, to reduce noise emissions where practicable.

The modelling of existing and Project noise emissions indicates that no privately owned residences would experience an increase in operational noise as a result of the development of the Project. At the majority of private residences that are located in close proximity to the Metropolitan Colliery surface facilities area, the Project is predicted to provide significant operational noise reductions in comparison to the existing noise emissions of the Metropolitan Colliery. Operational noise levels at receivers near the Project boundary to the north are generally predicted to remain unchanged by the Project (or be slightly reduced) due to the contribution of train loading activities which are in close proximity and dominate noise emissions at these locations.

No significant increases in existing road or rail transport noise or vibration are predicted with the implementation of the Project.

PRPs under the Metropolitan Colliery EPL provide an effective mechanism for progressive improvement of site noise performance. While this noise impact assessment indicates significant noise reduction would occur as a result of the development of the Project, it is recommended that the PRP process is continued to provide a mechanism to identify and implement further noise management or improvement measures that may be practicable over the life of the Project.

USE OF RURAL, SUBURBAN, URBAN AND URBAN/INDUSTRIAL INTERFACE NOISE AMENITY ZONES


The NSW Industrial Noise Policy (INP 2000) prescribes detailed calculation routines for establishing “project specific” LAeq(period) amenity (ie non-transport related) criteria for a development at potentially affected receivers. The INP’s noise amenity criteria are dependent on establishing the appropriate noise amenity zone (ie rural, suburban, urban etc) and the existing industrial noise level which are then used in conjunction with the Table 2.1 and Table 2.2 of the INP respectively.

Section 2.2.1 of the INP, Notes to Support the Noise Level Tables, states:

Rural - means an area with an acoustical environment that is dominated by natural sounds, having little or no road traffic. Such areas may include:

- an agricultural area, except those used for intensive agricultural activities - a rural recreational area such as resort areas - a wilderness area or national park - an area generally characterised by low background noise levels (except in the immediate vicinity of industrial noise sources).

This area may be located in either a rural, rural-residential, environment protection zone or scenic protection zone, as defined on a council zoning map (Local Environmental Plan (LEP) or other planning instrument).

Suburban - an area that has local traffic with characteristically intermittent traffic flows or with some limited commerce or industry. This area often has the following characteristics:

- decreasing noise levels in the evening period (1800-2200); and/or - evening ambient noise levels defined by the natural environment and infrequent human activity.

This area may be located in either a rural, rural-residential or residential zone, as defined on an LEP or other planning instrument.

Urban - an area with an acoustical environment that:

- is dominated by ‘urban hum’ or industrial source noise - has through traffic with characteristically heavy and continuous traffic flows during peak periods - is near commercial districts or industrial districts - has any combination of the above,

where ‘urban hum’ means the aggregate sound of many unidentifiable, mostly traffic-related sound sources.

The INP’s Application Notes dated July 2006 supersedes the INP’s Section 2.2.1 with respect the application of the Urban Industrial Interface and states:

Urban/Industrial Interface - this area may be located in either a rural, rural-residential or residential zone as defined on an LEP or other planning instrument, and also includes mixed land-use zones such as mixed commercial and residential uses.

The urban/industrial interface category in the INP recognises that the availability of noise mitigation measures might be limited for existing premises where residences are close to existing industries.

The urban/industrial interface amenity category applies only for existing situations (that is, an existing receiver near an existing industry) and only for those receivers in the immediate area surrounding the existing industry, that is, the region that extends from the boundary of the existing industry to the point where the noise level of the existing industry (measured at its boundary) has fallen by 5 decibels.

For new developments of a limited nature (such as an extension to existing process or plant or when replacing part of an existing process or plant with new technology) on existing sites (where the urban/industrial amenity category applies) then the urban/industrial amenity category is the appropriate amenity category for the new development.

Nature of Complaint



2006/7 Winder Driver (Gator). Also reported to DEC who contacted Gary Gibsons to follow-up on complaint

2/06/06 5.00 am


Noise coming from surface plant belt is keeping him awake and causing him stress. He sleeps with ear plugs and ear muffs to block the sound. Mr Lai also advised that he had previously considered acoustic screening of house but did not want to live in a prison.

Discussed with Mr Lai. Advised that we are in process of making improvements to Washplant to reduce noise levels and that I would inform him of progress. Consider that subject to success of PRP11 that double glazing windows facing mine may be warranted, or installation of acoustic screening along boundary. To review potential double glazing or screening as PRP11 progresses.

Tried to contact Mr Lai on two occasions. Spoke with Mr Lai’s wife and son a separate occasions and explained that the first step towards noise reduction would be closing in (sheeting) of the crusher building. Offered to provide diagrams, offer declined.

2006/08 Winder Druver 6/10/06 7.30 am


Had noticed that machinery was loud for the last few days. At 2.00am last night he put on ear plugs.

Discussed with Mr Lai that improvements were currently underway to close off the open side of the crusher building which will be completed in the next 2 weeks as well as installation of mufflers on the washery vacuum pumps which will reduce the constant background noise level. I informed Mr Lai that once the works were complete, that a noise expert would return to conduct another noise survey at the rear of his property.

2005/002 EPA 5/09/05 1.15 pm

Phone Oxley Pl Excessive noise from machinery at 1.35am, 3/9/05, keeping person awake and causing heart palpitations.

Washery was operating and in process of shutting down. There was a cracked trash screen deck on CV04, which would become noisy (rattling) when coal was not running on the belt. This appears to be the most probable cause. The cracked deck was repaired on Saturday 3/9/05.

Informed W Dave of outcome by Phone on 5/9/05.

2005/003 EPA 15/09/05 6.00 am

Phone Resident. Would not leave name or address, stated was abused in past

Heard noise from bulldozer at 2.00am and 4.00am Wednesday morning 14/09/05.

Sound did come from dozer, which has to refuel overnight when fuel truck does not service machines. Noise came from when dozer travelling over concreted pavement. Requested to SADA that on days when the fuel truck does not service machines that the dozer refuel late afternoon or early evening so that it has sufficient fuel to operate all night without having to refuel.

Inform Bob Buchanan (EPA) of findings by email on 19/09/05.

Resident of Oxley Pl for many years hears humming noise from colliery that seems to have increased over the last few years. Have noticed improvements as well particularly with the stone chute and reversing alarms but the humming noise is getting worse.

Inspected residence with Mr Lai and heard noise from the back of his property, which back onto the mine. Noise appears to come from either the washery (likely) or MD1 drivehead. Gave him the undertaking that it would be investigated and that I would feedback as information was available. Will contact DNA to carry out some noise measurements.

BACKGROUND NOISE MONITORING RESULTS - DECEMBER 2006


Overview of Methodology

A noise monitoring programme was commenced in December 2006 to quantify background noise levels (ie all noise sources) and to estimate industrial noise only (ie. in the absence of transport, natural and domestic noise). Four unattended noise loggers were positioned at representative residential localities adjacent to the Metropolitan Colliery site commencing Monday 29 December 2006 for a period of 10 days.

In order to supplement the unattended logger measurements and to assist in identifying the character and duration of the noise sources, operator-attended daytime, evening and night-time surveys were also conducted at all four logging locations.

The background noise monitoring programme was implemented in accordance with AS 1055-1997 “Acoustics-Description and Measurement of Environmental Noise” and the NSW Industrial Noise Policy (INP) 2000.

3.2 Instrumentation and Measurement Parameters

Unattended Monitoring and Operator-Attended Surveys

All acoustic instrumentation employed throughout the noise monitoring programme has been designed to comply with the requirements of AS 1259.2-1990, “Sound Level Meters” and carries current National Association of Testing Authorities (NATA) or manufacturer calibration certificates.

A description of instrumentation, designated type and serial numbers is shown in Table 1.

F19 19 Old Farm Road, Helensburgh Front of property n/a 193410

n/a Mine Managers Residence n/a Front of property TBA

All instrumentation was programmed to record continuously the noise exceedance levels in 15 minute intervals including the LAmax, LA1, LA10, LA50, LA90, LA99, LAmin and the LAeq.

Instrument calibration was conducted before and after each measurement survey, with the variation in calibrated levels not exceeding ±0.5 dBA.

Weather Station

Local meteorological data was obtained from a portable Automatic Weather Station located at the Mine Managers Residence at the eastern end of the Colliery site. The AWS recorded wind speed and direction, air temperature, relative humidity and rainfall in 15 minute intervals.

3.3 Unattended Background Noise Monitoring Results

The unattended background noise logger data from each monitoring location, together with the on-site weather conditions were analysed on a daily basis.

The statistical noise exceedance levels (LAN) are the levels exceeded for N% of the interval period. The LA90 represents the level exceeded for 90% of the interval period and is referred to as the average minimum or background noise level. The LA10 is the level exceeded for 10% of the time and is usually referred to as the average maximum noise level. The LAeq is the equivalent continuous sound pressure level and represents the steady sound level which is equal in energy to the fluctuating level over the interval period.


Page 2 of 4



Prior to further analysis, the background noise data from each location which correlated with periods of unstable weather (eg rainfall greater than 0.5 mm or wind speed greater than 5 m/s) were discarded. The acceptable background noise data was then processed in accordance with the INP “Appendix B - Applying the Background Noise Policy” to derive the Monday to Sunday background noise levels presented in Table 2.

3.4 Operator-Attended Background Noise Survey Results

Operator-attended noise surveys of 15 minutes duration were conducted with a precision integrating sound level meter in order to qualify the results obtained with the unattended noise loggers. During the attended noise surveys, the operator identified the character and duration of acoustically significant background noise sources. Wherever applicable, the operator described local traffic conditions and made a qualitative assessment of the prevailing weather conditions.

TRAFFIC NOISE MONITORING RESULTS - MARCH 2007


Overview of Methodology

A noise monitoring programme was commenced in March 2007 to quantify ambient noise levels (ie all noise sources) and to estimate traffic noise only (ie all vehicles). Three unattended noise loggers were positioned at representative residential localities adjacent to the Metropolitan Colliery off-site haulage routes commencing Wednesday 21 March 2007 for a period of 8 days.

In order to supplement the unattended logger measurements and to assist in identifying the character and duration of the noise sources, operator-attended daytime, evening and night-time surveys were also conducted at all three logging locations.

The background noise monitoring programme was implemented in accordance with AS 1055-1997 “Acoustics-Description and Measurement of Environmental Noise” and the NSW Environmental Criteria for Road Traffic Noise (ECRTN 1999).

3.2 Instrumentation and Measurement Parameters

Unattended Monitoring and Operator-Attended Surveys

All acoustic instrumentation employed throughout the noise monitoring programme has been designed to comply with the requirements of AS 1259.2-1990, “Sound Level Meters” and carries current National Association of Testing Authorities (NATA) or manufacturer calibration certificates.

A description of instrumentation, designated type and serial numbers is shown in Table 1.

Table 1 Acoustic and Meteorological Instrumentation Schedule

ID Location Noise Logger Off-set Distance Serial Number

L171 171 Lawrence Hargrave Drive, Helensburgh Near front boundary South 12 m 16-004-033

P170 170 Parkes Street, Helensburgh Near front boundary North 15 m 16-004-034

P83 83 Parkes Street, Helensburgh Adjacent front facade South 13 m 16-004-038

All instrumentation was programmed to record continuously the noise exceedance levels in 15 minute intervals including the LAmax, LA1, LA10, LA50, LA90, LA99, LAmin and the LAeq.

Instrument calibration was conducted before and after each measurement survey, with the variation in calibrated levels not exceeding ±0.5 dBA.

Weather Station and Traffic Counters

Local meteorological data was obtained from a portable Automatic Weather Station located at the Mine Managers Residence at the eastern end of the Colliery site. The AWS recorded wind speed and direction, air temperature, relative humidity and rainfall in 15 minute intervals.

3.3 Unattended Background Noise Monitoring Results

The unattended ambient noise logger data from each monitoring location, together with the on-site weather conditions were analysed on a daily basis.

The statistical noise exceedance levels (LAN) are the levels exceeded for N% of the interval period. The LA90 represents the level exceeded for 90% of the interval period and is referred to as the average minimum or background noise level. The LA10 is the level exceeded for 10% of the time and is usually referred to as the average maximum noise level. The LAeq is the equivalent continuous sound pressure level and represents the steady sound level which is equal in energy to the fluctuating level over the interval period.

TRAFFIC NOISE MONITORING RESULTS - MARCH 2007


Prior to further analysis, the ambient noise data from each location which correlated with periods of unstable weather (eg rainfall greater than 0.5 mm or wind speed greater than 5 m/s) were discarded. The acceptable ambient noise data was then processed in accordance with the ECRTN to derive the Monday to Sunday ambient noise levels presented in Table 2.

Note 1: Daytime/evening 0700 hours to 1200 hours, Night-time 2200 hours to 0700 hours

3.4 Operator-Attended Traffic Noise Survey Results

Operator-attended noise surveys of 15 minutes duration were conducted with a precision integrating sound level meter in order to qualify the results obtained with the unattended noise loggers. During the attended noise surveys, the operator identified the character and duration of acoustically significant ambient noise sources. Wherever applicable, the operator described local traffic conditions and made a qualitative assessment of the prevailing weather conditions.

The daytime operator-attended noise survey results are presented below:

NSW DECC CONSTRUCTION SITE NOISE GUIDELINE


CHAPTER 171 NOISE CONTROL GUIDELINE CONSTRUCTION SITE NOISE

Where there is likelihood of annoyance due to noise from construction sites, conditions such as the following may be specified in a development consent or building application.

This applies particularly to non-scheduled premises such as commercial buildings where a long construction time is not likely.

The criteria may not be applicable to long-term construction such as coal mines which may take several years.

Variations should be made according to local conditions.

Level Restrictions

i Construction period of 4 weeks and under.

The LA10 level measured over a period of not less than 15 minutes when the construction site is in operation must not exceed the background level by more than 20 dBA.

ii Construction period greater than 4 weeks and not exceeding 26 weeks.

The LA10 level measured over a period of not less than 15 minutes when the construction site is in operation must not exceed the background level by more than 10 dBA.

Time Restrictions

Monday to Friday 7.00 am to 6.00 pm.

Saturday 7.00 am to 1.00 pm if inaudible on residential premises, otherwise 8.00 am to 1.00 pm.

No construction work to take place on Sunday or Public Holidays.

Silencing

All possible steps should be taken to silence construction site equipment. It is particularly important that silenced equipment should be used on road or rail works where 24 hour operation is necessary.

VIBRATION DAMAGE AND ANNOYANCE RISK CRITERIA


Vibration - Building Structures

The German Standard DIN 4150-3:1999 “Structural Vibration Part 3: Effects of vibration in structures” provides the most recently updated criteria against which the likelihood of building damage from ground vibration can be assessed. The recommended limits for short and long-term vibration to ensure minimal risk of damage are presented numerically in Table 1.

Table 1 Guideline Values for Short and Long-term Vibration Effects on Structures (mm/s)

Short-term Vibration Long-term Vibration

At the Foundation Horizontal Plane of Highest Floor

Horizontal Plane of Highest Floor

Line Type of Structure

1 to 10 Hz

10 to 50 Hz

50 to 100 Hz1

All Frequencies All Frequencies

1 Buildings used for commercial purposes, industrial buildings and buildings of similar design

20 20 to 40 40 to 50 40 mm/s 10 mm/s

2 Dwellings and buildings of similar design and/or occupancy

5 5 to 15 15 to 20 15 mm/s 5 mm/s

3 Structures that, because of their particular sensitivity to vibration, cannot be classified under Lines 1 and 2 and are of great intrinsic value (eg buildings under preservation order)

3 3 to 8 8 to 10 8 mm/s 2.5 mm/s

Note 1: At frequencies above 100 Hz, the values given in this column may be used as the minimum values.

Vibration - Buried Pipework

DIN 4150-3:1999 also provides guideline values for evaluating the effect of vibration on buried pipework. The values are based on the assumption that pipes have been manufactured and laid using current technology. Additional considerations may be required at junctions. The recommended limits for short and long-term vibration to ensure minimal risk of damage are presented numerically in Table 2.

Table 2 Guideline Values for Short and Long-term Vibration Effects on Buried Pipes (mm/s)

Vibration Measured on the Pipe1 Pipe Material

Short-term Long-term

Steel (including welded pipes) 100 mm/s 50 mm/s

Clay, concrete, reinforced concrete, pre-stressed concrete, metal (with or without flange)

80 mm/s 40 mm/s

Masonry, plastic 50 mm/s 25 mm/s

Note 1: Mounting equipment directly onto pipes may not be possible. If the vibration source is not immediately next to the pipework, measurements can be made on the ground surface to obtain a conservative estimate.

Vibration - Human Comfort

NSW DECC has released “Assessing Vibration: A Technical Guideline” dated February 2006 which provides guideline building vibration levels associated with a low probability of annoyance to occupants arising from continuous (or impulsive) vibration sources. The DECC’s guideline is based on the information set out in British Standard 6472-1992 “Evaluation of Human Exposure to Vibration in Buildings (1 Hz to 80 Hz)” which defines levels of building vibration associated with a “low probability of adverse comment” from occupants. The applicable levels for continuous activities are shown in Table 3.

Table 3 Vibration Levels with “Low Probability of Adverse Comment” (1 Hz to 80 Hz)

Building Type Peak Floor Vibration (Horizontal Axis)

Peak Floor Vibration (Vertical Axis)

Critical Work Areas 0.40 mm/s 0.14 mm/s

Residential 0.8 mm/s to 1.6 mm/s (0.6 mm/s)1 0.3 mm/s to 0.6 mm/s (0.2 mm/s)1

Offices 1.6 mm/s 0.6 mm/s

Workshops 3.2 mm/s 1.2 mm/s

Note 1: Night-time criterion applicable only to residential dwellings.
