1 Introduction

Chain Valley Colliery is an underground coal mine located on the southern end of Lake Macquarie, approximately 100km north of Sydney and 60km south of Newcastle, adjacent to the Vales Point Power Station, producing thermal coal for the domestic and export markets.

A formal Environmental Management System (EMS) has been developed as a systematic and structured approach to managing environmental issues at the operation. This has been developed in general accordance with the requirements of the international standard ISO 14001.

This Noise Management Plan is an element of the Chain Valley Colliery Environmental Management System.

This Noise Management Plan has also been completed to satisfy the requirement of Condition 9, Schedule 3 of Development Consent SSD-5465, which states:

Chain Valley Colliery shall prepare and implement a Noise Management Plan for the development to the satisfaction of the Director-General. This plan must:

a) be prepared in consultation with the EPA and submitted to the Director-General for approval within 4 months of the date of this consent, unless otherwise agreed by the Director-General;

b) describe the measures that would be implemented to ensure compliance with the noise criteria and operating conditions in this consent;

c) describe the proposed noise management system in detail including the mitigation measures that would be implemented to minimise noise during construction and operations, including on and off site road noise generated by vehicles associated with the development; and

d) include a monitoring program that: • uses attended monitoring to evaluate the compliance of the development against the noise

criteria in this consent; • evaluates and reports on:

o the effectiveness of the on-site noise management system; and o compliance against the noise operating conditions; and

• defines what constitutes a noise incident, and includes a protocol for identifying and notifying the Department and relevant stakeholders of any noise incidents.

2 Purpose

The purpose of this Noise Management Plan is to:

• detail the noise impact assessment criteria applying to the site;

• detail the long term noise goals at nearby receivers;

• identify the noise monitoring and reporting requirements;

• detail the noise management measures;

• identify the requirements for noise incident reporting and reviews of the document; and

• identify persons responsible for implementation of requirements.

3 Background

3.1 Operations

Chain Valley Colliery is an underground coal mine, currently coal mining methods include development of roadways in the coal seam known as first workings. These first workings develop panels to support the installation of a miniwall, a modern secondary coal extraction method.

Coal from both the first and second workings are transported out of the mine via a conveyor system, where the coal is sized and transported by surface conveyor systems to product bins.

If the coal is not able to be loaded and hauled directly from the product bins to the customer or port by truck, then it is stored on the stockpile area, prior to being sold and transported from site.

As a result of the above processes, support activities and processes, the following activities have been identified as the major sources of noise generation:

• Surface compressors; • Surface conveyors; • Screener/shaker; • Secondary sizer; • Filling trucks from the product bins; • Truck idling and movements (internal); • Front end loader operation; • Bulldozer operation; • Ventilation fans; • Diesel powered flood lighting; • Belt/equipment movement alarms; and • Truck movements on public roads.

This noise management plan aims to identify existing noise management controls, proposed controls and monitoring to determine compliance or otherwise.

3.2 Noise Criteria

The Environmental Impact Statement completed for the Chain Valley Colliery Mining Extension 1 Project (EMM, May 2013) and additional submission reports (EMM, August 2013 and EMM, October 2013) modelled noise levels at residential locations in the vicinity of the project, these modelled levels are reflected in the noise impact assessment criteria that are detailed in Condition 7, Schedule 3 of Development Consent SSD-5465.

These noise criteria, which apply at receivers surrounding the Colliery, are shown on Table 1. The receiver locations referenced in Table 1 are displayed on Figure 1.

Notes: • To interpret the locations referred to in Table 1, see Figure 1 and the EIS; and • Noise generated by the development is to be measured in accordance with the relevant requirements, and exemptions

(including certain meteorological conditions), of the NSW Industrial Noise Policy. Appendix 8 of the Development Consent sets out the meteorological conditions under which these criteria apply, and the requirements for evaluating compliance with these criteria.

As per Condition 7, the criteria in Table 1 do not apply if the Applicant (in this instance, LakeCoal) has a written agreement with the relevant landowner to exceed the noise criteria, and the Applicant has advised the DP&I in writing of the terms of this agreement.

The noise criteria in Table 1 are to apply under all meteorological conditions except the following (ref Appendix 8 of Development Consent SSD-5465):

(a) during periods of rain or hail;

(b) average wind speed at microphone height exceeds 5 m/s;

(c) wind speeds greater than 3 m/s measured at 10 m above ground level; or

(d) temperature inversion conditions greater than 3°C/100 m.

3.3 Long Term Noise Goals

As Chain Valley Colliery has been operating for approximately 50 years, some of the predicted noise impacts at local receivers are greater than would usually be permissible without the requirement to offer noise treatments or voluntary acquisition. In the case of Receiver 22 (R22), replacement of the old axial fan with new centrifugal fans, has reduced the noise levels at this residence but were still unable to satisfy the project specific noise levels (PNSLs). In this instance, LakeCoal have been set a number of requirements to facilitate the long term noise emissions from the site moving toward to the equivalent of the PNSLs.

The long term noise goals are reproduced in Table 2, mechanisms that will be used to achieve these goals are discussed in Section 4.

Notes: • To interpret locations referred to in Table 2, see Figure 1; and • Noise generated by the development is to be measured in accordance with the relevant requirements, and exemptions

(including certain meteorological conditions), of the NSW Industrial Noise Policy. Appendix 8 of the Development Consent SSD-5465 sets out the meteorological conditions under which these criteria apply, and the requirements for evaluating compliance with these criteria.

3.4 Consultation

The Noise Management Plan was required to be prepared in consultation with the EPA. A draft of the Noise Management Plan was provided to the EPA on the 14th February 2014 and subsequently on the 27th February 2014 LakeCoal received correspondence back from the EPA. The EPA commented that while they encourage the development of such plans, they do not review these documents as their role is to set environmental objectives, but not to be directly involved in the development of strategies to achieve those objectives. Accordingly, they provided no comments on the Noise Management Plan.

4 Noise Management

For the activities with potential to increase noise emissions (specifically identified in Section 3.1) the following controls are implemented to minimise, monitor and manage the noise impacts and emissions from Chain Valley Colliery:

• Coal haulage, both on private property and on public roads, is undertaken using road registered trucks with adequate exhaust systems;

• Air compressors are contained within a 3 sided enclosure to limit noise propagation; • The transfer of coal into the surface ROM bin is enclosed; • The upgraded ventilation fans had acoustic modifications and design changes applied to target noise

reductions and reduce tonal noise associated with the old fan installation, including; acoustic enclosure of the fan motors; silencers on the inlet side of the main impeller housing; outlet silencers on the vertical stack of each fan and increased fan casing thickness.



Coordinator of 20


• Haulage operations on public roads are only undertaken between the hours of 5:30am and 5:30pm Monday to Friday, not at all on weekends or public holidays;

• Haulage operations to Vales Point Power Station are restricted during the hours of 10pm to 5:30am during Spring and Autumn months and not permitted between 10pm and 5:30am during Winter months.

• Dispatch of coal laden trucks is restricted to 32 per hour, and a maximum of 270 per day on public roads;

• Major surface electrical motors and components for the haulage and transport system and conveyor system are contained within buildings;

• The conveyor transfer point into the final product bin is enclosed; • Primary coal crushing and sizing occurs underground; • Attended monitoring is undertaken quarterly (during day, evening and nigh time periods) and

provides results to identify potential or actual non-compliances and primary noise sources, which will allow any necessary management actions to be developed based on ongoing monitoring; and

• Monitoring includes the use of real-time noise monitoring with noise level based email alerts and web-based real-time noise monitoring with audio streaming to allow remote determination of noise sources.

The personnel responsible for the above management measures are detailed in Section 8 (Roles and Responsibilities).

Since the last revision of the noise management plan, a stacker conveyor for product coal stockpiling has also been commissioned, removing the need for trucks to undertake stockpiling activities from the final product bin.

Additional noise management and mitigation measures to further reduce noise impacts and emissions are to be investigated and implemented if determined to be feasible, these include:

• Additional acoustic treatment for the main ventilation fans noise; • Modification to belt/movement alarms; • Surface conveyor and coal preparation equipment; • Sound attenuation options for the surface bulldozer and front end loader; • Placement of acoustic barriers; • Attenuation options for the surface screener/shaker; • Quiet rollers for surface conveyor belts; and • Acoustic treatments around compressors.

In addition to the above LakeCoal is also investigating the potential to connect Chain Valley Colliery to Mannering Colliery and transport coal via an existing overland conveyor system to Vales Point Power Station, which would reduce noise associated with internal truck movements.

Further actions for reducing noise impacts would be implemented as determined by the noise audits, which are to be completed in conjunction with each independent environmental audit (refer Section 9.3).

5 Noise Monitoring

5.1 General Requirements

All attended noise monitoring undertaken as part of the noise monitoring program shall be in accordance with the requirements of Australian Standard (AS) 1055:1997 Acoustics - Description and Measurement of Environmental Noise and the NSW Industrial Noise Policy (INP).

Attended noise monitoring would be conducted quarterly and additional monitoring may also be conducted in if it is identified that a particular landholder/locality requires further investigation. Each quarterly noise survey will comprise three (3) measurements at each attended monitoring location (refer Section 5.2).



Coordinator of 20


During each quarterly attended noise monitoring period monitoring will be conducted during day, evening and night time periods (as defined in the INP) to ensure all operational and atmospheric scenarios are captured.

Noise monitoring will consist of both attended and real-time monitoring. Attended measurements will be undertaken and assessed by a suitably qualified person who would be engaged to complete the monitoring. Real-time monitoring will be managed by onsite personnel who have been trained in the operation of the real-time monitor and if required additional analysis could also be undertaken by a suitable qualified acoustics specialist.

If at any time during monitoring, meteorological conditions exceed the applicable meteorological conditions within the INP, then monitoring and reporting will still be carried out, however it will be outlined within the report what the meteorological conditions were at the time and if the criteria still applied due to these conditions.

All acoustic instrumentation used for the monitoring will have current calibration certificates and shall be designed to comply with the requirements of AS IEC 61672.1:2004 Electroacoustics - Sound level meters - Specifications.

During attended monitoring, the following information will be recorded:

• Person undertaking the monitoring; • locations of monitoring; • recording intervals; • meteorological conditions; and • notes identifying all noise sources.

The results from the attended monitoring, including determination of compliance with noise criteria, would be undertaken and reported back to LakeCoal in a formal report to be provided quarterly following the completion of each quarterly monitoring period.

In addition to the formal report provided on a quarterly basis, the monitoring consultant is to be instructed to report any noise incidents (refer Section 6.1) as soon as practicable to the Environment and Community Coordinator who will commence the non-compliance reporting process as detailed in Section 6.2.

5.2 Monitoring Locations

Figure 2 presents the locations of the seven (7) attended noise monitoring locations and one (1) real-time noise monitoring location. The locations have been selected taking into account local meteorological conditions, the proximity of surrounding residences and the modeling undertaken as part of the acoustic assessment that accompanied the environmental impact statement, the most recent of which was contained within the response to submissions document report (EMM 29th October 2013).

LakeCoal will undertake monitoring at the following locations in order to verify compliance with the noise criteria in the development consent, as shown in Section 3.2. The monitoring locations for the attended noise monitoring and real-time monitoring are presented on Figure 2 and consist of:

• seven (7) attended noise monitoring sites (ATN001 to ATN007); and • one (1) real-time noise monitor (RTN001).

The site reference, receiver ID (from the acoustic assessment), property location and GPS position of each noise monitoring site, is identified in Table 3.

6 Incident & Compliance Management

6.1 Introduction

A noise incident is deemed to occur when noise generated at the Colliery, or in association with the Colliery operations, results in an exceedance of the noise criteria applicable at that specific monitoring location (as detailed in Section 3.2).

The attended noise monitoring results will be reviewed on a quarterly basis as reports are received to confirm compliance with the conditions specified in Section 3.2 or ensure corrective action is taken where results or trends indicate non-compliance or risk of future non-compliance to the development consent impact assessment criteria.

The monitoring results will also be included in the Annual Review. The Annual Review will include a summary of monitoring results during the past year, comparison against the noise impact assessment criteria, summary of previous years monitoring results and comparison against predictions in the Environmental Impact Statement. The Annual Review will also identify any trends in noise levels and identify any noise incident over the year as well as describing any actions currently implemented or planned to ensure compliance with the noise impact assessment criteria and long-term noise goals. The Annual Review will be forwarded to the relevant authorities including the Department of Planning and Infrastructure and Environment Protection Authority. The Annual Review will also be forwarded to members of the Community Consultative Committee and local Councils (Wyong and Lake Macquarie). It will also be placed on the company’s website along with a summary of environmental monitoring results.

6.2 Incident or Non Compliance Reporting

If monitoring reveals that a noise incident has occurred due to the operations from Chain Valley Colliery then LakeCoal will conduct an investigation into the cause of the noise incident. The investigation will consider any activities and plant operation or other factors that may have generated the non-compliance. The report will be provided to the Director-General Department of Planning and Infrastructure, Environment Protection Authority and landowner where the noise incident occurred.

The report will:

a) describe the date, time and nature of the noise incident; b) identify the cause (or likely cause) of the noise incident; c) describe what action has been taken to date; and d) describe the proposed measures to address the noise incident.

LakeCoal will implement the recommendations of the investigation in order to address any future non-compliance issues.

Additional details of the incident reporting process are provided in the Environmental Management Strategy (OMP-D-16374).

7 Stakeholder Management and Response

7.1 Complaint Protocol



Coordinator of 20


LakeCoal has a 24-hour telephone hotline (1800 687 557) for members of the public to lodge complaints, concerns, or to raise issues associated with the operation. This service aims to promptly and effectively address community concerns and environmental matters.

The full details of the complaints line are covered in the Environmental Management Strategy (OMP-D-16374), but in summary, all complaints are recorded and responded to, if for some reason no action is taken then the reason why is recorded. The information recorded in the complaint register includes;

• date and time the complaint was lodged; • personal details provided by the complainant; • nature of the complaint; • action taken or if no action was taken, the reason why; and • follow up contact with the complainant.

7.3 Dispute Resolution

If any disputes are not adequately addressed by the complaints handling process then they will be handled by the site Environment and Community Coordinator, if the response of LakeCoal is not considered to satisfactorily address the concern of the complainant, a meeting will be convened with the General Manager together with the Environment and Community Coordinator.

The complainant will be advised of the outcomes from the meeting and the actions to be implemented as a result.

After implementation of the proposed actions the complainant will be contacted and advice sought as to the satisfaction or otherwise with the measures taken.

If no agreed outcome is determined or the complainant is still not satisfied by the action taken, then an Independent Review may be requested by the. If determined to be warranted by the Director-General, an Independent Review will be undertaken in accordance with the requirements of the development consent to achieve an outcome to the satisfaction of the Director-General.

Sound Power Level (Lw) The Sound Power of a source is the rate at which it emits acoustic energy. As with Sound Pressure Levels, Sound Power Levels are expressed in decibel units (dB or dBA), identified by the Lw, or by the reference unit 10-12 W. The relationship between Sound Power and Sound Pressure may be likened to an electric radiator, which is characterised by a power rating, but has an effect on the surrounding environment that can be measured in terms of a different parameter, temperature.

Sound Pressure Level (Lp) The sound pressure relative to a standard reference pressure of 20µPa (20x10-6 Pascals) on a decibel scale.
