INTRODUCTION 1.1 Purpose Printed By: Management Plan MP.HS.387 Status:Approved Version:7.0 Doc ID:387 Page 3 of 38 The purpose of this noise management plan (NMP) is to set out the requirements for the management and monitoring of noise associated with PKCT s site operations. This plan has been prepared in accordance with the Department of Planning and Infrastructure (DPI) s approval conditions (refer Section 5.3 herein) which includes a requirement for PKCT prepare and implement a noise monitoring program. 1.2 Background Port Kembla Coal Terminal (PKCT) provides a coal and bulk products receival, storage and shipping loading service to its customers. PKCT is located on north side of the inner harbour and operates premises leased from the Port Kembla Port Corporation. PKCT has been operating since August 1990 and has an office of Environment and Heritage Environmental Protection Licence (EPL) to operate. Noise is an environmental aspect with the potential to impact on the amenity of the community. This aspect is managed through PKCT s environmental management system which has quality certification to ISO In June 2009, the Department of Planning and Infrastructure issues PKCT approval no. 08_0009 which set new approval conditions for PKCT s operations including some pertaining to noise. This has required development of a noise monitoring program. Program has been developed in consultation with the Office of Environment and Heritage and is incorporated in this management plan (NMP). 1.3 Scope This NMP applies to activities and aspects of PKCT operations with the potential to result in noise impacting on amenity on site and on the community and stakeholders external to PKCT s premises. This NMP does not cover health aspects associated with noise and hearing loss. PKCT has health and hygiene management processes and programs covered elsewhere within its management system to cover this aspect.

MANAGEMENT STRATEGIES Printed By: Management Plan MP.HS.387 Status:Approved Version:7.0 Doc ID:387 Page 7 of Operational Activities and Potential Noise Issues Environmental impact of noise associated with PKCT s operation was taken into account in the Environmental Impact Assessment which preceded approval and construction of the coal terminal. From time to time, further assessments have been undertaken for OH&S and Environmental reasons. Noise has not been a significant environmental issue in the operation of PKCT. Excessive noise is more likely to be incident based e.g. roller requiring maintenance rather than the day to day noise levels being generated by PKCT. There are a number of on site noise sources, however, which generate noise above 85dB. Key noise sources are as follows:- Operating conveyors particularly around the head end of conveyors Ship loader boom hoist area Transfer Station 6 Rail Receival- trains/ wagon doors Portable equipment such as angle grinders Truck compression braking, tail gates, hoists 6.2 Environmental Aspects and Impacts Potential for noise impacting on site and on the community is recognised as an environmental aspect and included in PKCT s Environmental Aspects and Impacts Register RG.HSEC Historically, noise has not been the subject of community complaints. Rather, it has been a health and hygiene issue in terms of exposure to site personnel when working in proximity to operating equipment. There are a number of locations which have been identified requiring mandatory hearing protection. Many of these locations are within enclosed structures so that the associated noise off site is diminished. Residential areas are in close proximity to the north of PKCT s site, 800 metres to the north of site entrance at Port Kembla Road. This area has realised significant development in recent years resulting in increasing resident density and a changing demographic. PKCT strategic reviews have concluded that the community are likely to have less tolerance for the neighbouring industrial precinct on aspects impacting on their amenity.

Higher than normal noise level may also occur if an equipment component is faulty and requires maintenance. When carrying out plant and equipment inspections and maintenance, consideration needs to be given to plant and equipment emitting unusually high noise levels and, if detected, the necessary repairs shall be carried out as appropriate. Impact of noise nuisance on community is a consideration when planning work. In particular, certain types of maintenance and construction work e.g. jack hammering, pile driving, demolition may result in unacceptable noise levels at night. Work needs to be programmed to allow for this or effective sound insulation barriers or other mitigation measure need to be provided. Noise impacts (operating and during construction) need to be taken into account when considering plant modifications, upgrades and new equipment. Environmental Management System PKCT EMS system is documented, controlled and supported by management plans and procedures with processes covering:- Environmental aspects and impacts Planning and objectives Legal and other requirements Training and competency Emergency Management and Investigation Monitoring, Auditing and Review Noise Controls Equipment and processes established on site to control noise include the following:- Rail receival enclosed within a shed Road and Rail Receival conveyors initially underground then enclosed within conveyor galleries and transfer stations This is a Controlled Document in SharePoint Controlled Documents Library UNCONTROLLED IF VIEWED OUTSIDE OF SHAREPOINT; valid for 48 Hours from time printed.

External noise consultant expertise is used where appropriate to identify improvement opportunities. Networking is also undertaken with other coal terminals and within the industry to:- Ensure PKCT has up to date knowledge of best practice noise management methodologies when developing improvement strategies. Benchmark noise levels with other bulk terminals to check its performance Site noise surveys and mapping is undertaken from time to time to assess on site noise sources and external impacts associated with PKCT s operations. 7. EVENT MANAGEMENT 7.1 Emergency Response and Investigation PKCT has emergency response processes in place in case of significant noise events which may be observed internally through site observations or through an external community or stakeholder complaint. These processes provide for action to be taken to mitigate impacts. Events are investigated to develop corrective actions.

17 Page 5 1. Introduction This Noise Monitoring Program (NMP) has been prepared to address the requirements for noise monitoring as outlined in the Department of Planning s (DoP) Conditions of Approval (CoA) (08/0009), dated 12 June Please note that the Department of Planning is now known as Department of Planning and Infrastructure (DPI). The objective of this program is to: have a robust noise monitoring procedure that will identify noise levels from Port Kembla Coal Terminal (PKCT) and clearly identify compliance (or otherwise) with the Impact Assessment Criteria; and provide monitoring information and advice to ensure that noise emissions from the site are appropriately managed and where necessary reduced. This protocol is not intended to be a static document, it will be maintained and updated as further information or suggestions become available.

18 Page 6 2. Site Description The Port Kembla Coal Terminal (PKCT) is a major coal intermodal facility that receives coal by road and rail for loading onto ships for export. Currently PKCT site operations are permitted 24 hours per day, 7 days per week. The site operations typically include: Delivery of material by road and rail to receival hoppers; Transfer of received coal via conveyor to stackers to be stockpiled prior to arrival of ship; Transfer of products received to Bulk Product Berth to stockpile via front end loader; Movement of stockpiled coal to the ship loader using bucket wheel reclaimers and conveyors; Loading of coal to ship using the ship loader at Berth 102; and Loading of product received at Bulk Product Berth to ship via ship loader at Berth 101. Figure 2-1 shows the site plan of the PKCT site.

20 Page 8 3. Legislative & other requirements 3.1 Legislative Requirements Legislation relating to the management of noise includes: Protection of the Environment Operations Act 1997 (POEO Act); Protection of the Environment Operations (General) Regulation 1998; and Protection of the Environment Operations (Noise Control) Regulation Conditions of Approval The CoA specifies the requirements with which PKCT must comply during its operations, with respect to noise, this includes the following: NOISE Impact Assessment Criteria 1. The Proponent shall ensure that the noise generated by the project at any privately-owned residence does not exceed the criteria specified in Table 1 for the location nearest to that residence. Table 1 Noise impact assessment criteria db(a) L Aeq,(15min) Notes: Location Cnr Swan & Kembla Streets Cnr Swan & Corrimal Streets Cnr Keira & Fox Streets Time Period Noise Criteria L Aeq,(15min) (dba) Day 51 Evening 50 Night 49 Day 51 Evening 50 Night 49 Day 55 Evening 49 Night 45 a) To determine compliance with the L Aeq,(15min) noise level limits in the above table, noise from the project is to be measured at the most affected point within the residential boundary. Where it can be demonstrated that direct measurement of noise from the project is impractical, the DECC may accept alternative means of determining compliance (see Chapter 11 of the NSW Industrial Noise Policy). The modification factors in Section 4 of the NSW Industrial Noise Policy shall also be applied to the measured nois levels were applicable. b) The noise emission limits identified in the above table apply under meteorological conditions of: - wind speecs of up to 3m/s at 10m above ground level; or - temperature inversion conditions of up to 3ºC/100m, plus a 2m/s source-to-receiver component drainage flow wind at 10m above ground level for those receivers where applicable in accordance with the NSW Industrial Noise Policy.

21 Page 9 However, if the Proponent has a written negotiated noise agreement with any landowner of the land listed in Table 1, and a copy of this agreement has been forward to the Department and DECC, then the Proponent may exceed the noise limits in Table 1 in accordance with the negotiated noise agreement. Noise Monitoring Program 2. The Proponent shall prepare and implement a Noise Monitoring Program for the project to the satisfaction of the Director-General. This program must: a) be developed in consultation with DECC. b) be submitted to the Director-General for approval within 6 months from the date of this approval, or as otherwise agreed by the Director-General; and c) include a: - combination of attended and unattended noise monitoring measures; - noise monitoring protocol for evaluating compliance with the noise impact assessment criteria in this approval; and - reasonable and feasible best practice noise mitigation measures to ensure project specific noise criteria are met. Note that the Department of Environment and Climate Change (DECC) became the Department of Environment, Climate Change and Water (DECCW), however is now known as the Office of Environment and Herritage (OEH).

22 Page Noise monitoring 4.1 Responsibilities Table 4-1 presents the personnel at PKCT who are responsible for noise monitoring. Table 4-1 Responsibilities for Noise Monitoring Procedure Responsibility Ensuring environmental noise monitoring is carried out Confirming typical operations during noise monitoring Record noise monitoring results Where the levels exceed the targets, implement further controls Risk Manager Operations Manager Risk Manager Operations Manager 4.2 Monitoring Standards Noise monitoring at PKCT will be undertaken in general accordance with all relevant Australian Standards, Legislation and OEH approved methods for monitoring. The relevant documents are listed below: AS : Acoustics Measurement and Description of Environmental Noise; Part 1: General procedures AS IEC Electoacoustics Sound Level Meters. Environmental Noise Control Manual (EPA, 1994); NSW Industrial Noise Policy (EPA, 2000); and NSW Road Noise Policy (DECCW, 2011). 4.3 Monitoring Locations Noise monitoring during operations will be undertaken at the locations specified in Table 4-2 representing the catchments areas shown in Figure 4-1. Specific monitoring locations are shown in Figures 4-2 to 4-4. These monitoring locations have been selected as they are representative of potentially impacted residences surrounding PKCT.

23 Page 11 Table 4-2 Responsibilities for Noise Monitoring Location Description Residential Receivers 1 Corner of Swan and Kembla Sts Swan St, between Keira and Corrimal Sts 2 Corner of Swan and Corrimal Sts Swan St, east of Corrimal Sts 3 Corner of Keira and Fox Sts Keira St, between Swan and Fox Sts 4.4 Monitoring Protocol To adequately sample the noise environment surrounding PKTC bi-annual monitoring will be conducted. Noise monitoring needs only to be conducted at night as this would be the most appropriate time to conduct the measurement for the following reasons: The site operates 24 hours without any operational discrimination between day, evening and night. During the night, the lowest criterion applies and as such compliance with this criterion will lead to compliance during the evening and night. Atmospheric conditions that enhance noise propagation during the night are more likely to occur during the night. Given the generally lower ambient noise levels in the area at night, there is a higher chance that noise from PKCT would detected. Monitoring shall be bi-annually for a single night time period during Winter and Summer. The frequency of monitoring shall be reviewed after 12 months of operations. The Conditions of Approval require both attended and unattended noise monitoring however, the acoustic environment in the area is complex and given the fact that the residential receivers are separated by roads and a park, unattended noise monitoring is unlikely to provide any useful information regarding the noise from PKCT. Noise levels other than from PKCT need to be excluded from the measured level. As such, traditional attended noise monitoring using a unidirectional sound level meter is not suitable for this noise environment. The noise environment around PKCT is dominated by traffic noise from all areas and other industrial sites around the area which unidirectional noise monitoring can not discern. Therefore, the directional BarnOwl unattended noise monitoring system will be utilised for the noise monitoring. Using the directional BarnOwl system will provide the opportunity for identifying noise from the PKCT site (i.e. PKCT direction) and where measureable, quantify such levels.

24 Page 12 Figure 4-1 PKCT and Surrounding Receivers Residenc N Attended noise monitoring would be conducted at each of the three locations throughout the night (10.00pm to 7.00am). The monitoring interval shall be a 15 minute period with at least two intervals captured. In the event that monitoring is to be conducted during the day or evening, a single monitoring period shall be sufficient. The representative arc used for the directional noise monitor for each measurement location is presented in Figures 4-2, 4-3 and 4-4. Both the exact monitoring location and arc used may change slightly in an event where noise from nearby activities might interfere with the noise measurement. It should be noted that BarnOwl measures in 5 degree increments.

25 Page 13 Received levels from various noise sources would be noted during attended monitoring and particular attention will be paid to the extent of the PKCT noise contribution, if any. As a minimum for each receptor location, the L Aeq PKCT Direction (in the absence of any other noise) shall be quantified. This parameter would be calculated from measurements using the BarnOwl directional noise monitoring system (refer to Appendix B) and will be assessed against the criteria. The L A90 parameter will also be recorded as well as any maximum noise levels. If, at any time during monitoring, meteorological conditions exceed the conditions identified under Note (b) of Section 3-2, monitoring and reporting will still be carried out, however it will be outlined within the report that meteorological conditions were in exceedance of applicable levels, and as such the limits identified within Section 3-2 will not apply to the results obtained under such conditions. In addition, meteorological conditions will be obtained for the time of monitoring. This is to include wind speed and direction as well as data suitable for quantifying the presence or otherwise of temperature inversions from PKCT s two weather stations.

27 Page 15 Figure 4-3 Noise Measurement Sector for Location 2 Location 2 30 degrees

28 Page 16 Figure 4-4 Noise Measurement Sector for Location 3 Location 30 degrees 4.5 Summary of Attended Monitoring Frequency: Monitoring shall bi-annually for a single night time period within the winter and summer seasonal period.

29 Page 17 Interval: Attended noise monitoring would be conducted at each of the three locations throughout the night (10.00pm to 7.00am). The monitoring interval shall be a 15 minute period with a minimum two measurements to be conducted for the night time period. Parameters: Parameters to be recorded includes L Amax, L Aeq, 15min and L A90, 15min. Instruments: Instruments used for unattended monitoring shall be the BarnOwl direction noise monitoring system. Directional noise monitoring provides source detection and analysis of noise from the PKCT (See Figure 4-2, 4-3 and 4-4). Locations: BarnOwl uses 3 microphones spaced 500mm apart. The microphone signals are digitised using 24-bit, state-of-the-art A-D conversion. Specially-developed, optimised signal analysis software allows inter-microphone time differences (and therefore source directions) to be evaluated for a ½-second noise sample while the next sample is being acquired. BarnOwl can therefore provide real time tracking of noise sources, with source locations displayed on a monitor and/or saved for later analysis. The system can simultaneously record total noise, and a filtered signal excluding high-frequency sources such as insects. BarnOwl measures in 5 degree increments. Measurements methodology shall be in general compliance with Australian Standard 1055 Acoustics- Description and Measurement of Environmental Noise. Pre and post calibrations shall be recorded. Observation Logs: Location 1 Corner Swan and Kembla Streets; Location 2 Corner Swan and Corrimal Streets; and Location 3 Corner Keira and Fox Streets. Outdoor noise levels should normally be measured 1.2m 1.5m above ground level. The position(s) should be located within the apparent boundaries of land or within 30m of an effected residential receiver. The arc used shall be recorded for each location. During the noise measurements, the operator shall record any significant noise sources generated on-site by PKCT. It is recommended that any observations of noise from PKCT trucks are also taken. In addition the general ambient noise and weather are to be recorded. Following the completion of measurements, PKCT shall provide Wilkinson Murray (WM) with a summary of the site activities that occurred during the monitoring period. The summary shall include number of truck/rail movements, ships loaded and times. 5. Reporting The following information should be provided in the compliance noise measurement

30 Page 18 report. 1. Description of Source(s) and Surroundings The report should include the following: description of the sound source(s); location of source(s); description and sketch of physical environment e.g. trees, structures, reflecting objects, topographical features, and any other relevant features; photographs if appropriate; operating conditions of sound source(s). 2. Instrumentation For all items of equipment used for the measurements, including calibration equipment, the following information should be recorded: name; manufacturer; type; serial number(s) (also of microphones, if removable); record of field calibration; and; date of most recent laboratory calibration. 3.

The report should include the following, as appropriate: mean wind speed; mean wind direction; Rain fall; Sigma theta and Pasquill stability class. 5. Site Operational Reports PKCT shall provide WM with a summary of all operations that occurred during each noise monitoring period. The summary should include the following: Truck movements. Rail movements and start/stop time for unloading. Ship loading and start/stop time for loading. 6. Statement of Compliance A noise compliance monitoring statement will be submitted for each monitoring period. The Report will report compliance with the operational noise limits specified in the DPI Approval.

32 Page Review Monitoring results will be reviewed on a bi-annual basis following the conclusion of the monitoring period by the Risk Manager to assess compliance with the noise criteria presented in Section Corrective Action In the event that the monitoring program or local community identifies an exceedance of the noise criteria stipulated in the development consent, the Risk Manager will investigate the noise source and appropriate corrective action will be undertaken. In the event that the investigation determines that noise from PKCT operations is likely to be responsible for an exceedance of the noise criteria at nearby residences the Director-General of DPI will be notified. Monitoring results will be published in PKCT s Annual Environmental Management Report. 6.2 Complaints A procedure for handling complaints has been implemented as part of the PKCT Environmental Management System (EMS) to ensure a consistent approach to handling any complaints. All legitimate complaints will be investigated by the PKCT Risk Manager. Feedback to the complainant will be provided. In addition to the monitoring outlined in this plan, if PKCT receives a complaint regarding noise at a particular location, specific monitoring may be undertaken to quantify the potential noise impact. 6.3 Review The noise monitoring program is to be reviewed in consultation with OEH and DPI at least every three years. The review will reflect changes in environmental expectations technology and operational procedures. If no exceedance of the criteria occurs for 6 years noise monitoring will not be required to continue.

33 APPENDIX A GLOSSARY

34 Appendix A-1 GLOSSARY Most environments are affected by environmental noise which continuously varies, largely as a result of road traffic. To describe the overall noise environment, a number of noise descriptors have been developed and these involve statistical and other analysis of the varying noise over sampling periods, typically taken as 15 minutes. These descriptors, which are demonstrated in the graph overleaf, are here defined. Maximum Noise Level (L Amax ) The maximum noise level over a sample period is the maximum level, measured on fast response, during the sample period. db(a) A-weighted decibels. The ear is not as effective in hearing low frequency sounds as it is hearing high frequency sounds. That is, low frequency sounds of the same db level are not heard as loud as high frequency sounds. The sound level meter replicates the human response of the ear by using an electronic filter which is called the A filter. A sound level measured with this filter switched on is denoted as db(a). Practically all noise is measured using the A filter. Frequency Frequency is synonymous to pitch. Sounds have a pitch which is peculiar to the nature of the sound generator. For example, the sound of a tiny bell has a high pitch and the sound of a bass drum has a low pitch. Frequency or pitch can be measured on a scale in units of Hertz or Hz. Impulsive Noise Having a high peak of short duration or a sequence of such peaks. A sequence of impulses in rapid succession is termed repetitive impulsive noise. Intermittent Noise The level suddenly drops to that of the background noise several times during the period of observation. The time during which the noise remains at levels different from that of the ambient is one second or more. L A1 The L A1 level is the noise level which is exceeded for 1% of the sample period. During the sample period, the noise level is below the L A1 level for 99% of the time. L A10 The L A10 level is the noise level which is exceeded for 10% of the sample period. During the sample period, the noise level is below the L A10 level for 90% of the time. The L A10 is a common noise descriptor for environmental noise and road traffic noise. L A90 The L A90 level is the noise level which is exceeded for 90% of the sample period. During the sample period, the noise level is below the L A90 level for 10% of the time. This measure is commonly referred to as the background noise level. L Aeq The equivalent continuous sound level (L Aeq ) is the energy average of the varying noise over the sample period and is equivalent to the level of a constant noise which contains the same energy as the varying noise environment. This measure is also a common measure of environmental noise and road traffic noise. ABL The Assessment Background Level is the single figure background level representing each assessment period (daytime, evening and night time) for each day. It is determined by calculating the 10 th percentile (lowest 10 th percent) background level (L A90 ) for each period. RBL The Rating Background Level for each period is the median value of the ABL values for the period over all of the days measured. There is therefore an RBL value for each period daytime, evening and night time.

35 Sound Pressure Level (dba) Appendix A-2 Sound Absorption The ability of a material to absorb sound energy through its conversion into thermal energy. Sound Level Meter An instrument consisting of a microphone, amplifier and indicating device, having a declared performance and designed to measure sound pressure level. Sound Pressure Level The level of noise, usually expressed in decibels, as measured by a standard sound level meter with a microphone. Tonal Noise Containing a prominent frequency and characterised by a definite pitch. 60 Typical Graph of Sound Pressure Level vs Time L Amax L A1 L A10 L Aeq L A50 L A :00 3:00 6:00 9:00 12:00 15:00 Monitoring or Survey Period (5 sec samples)
