Gloucester Gas Project DRAFT Introduction Central Processing Facility Construction Environmental Management Plan

1.0 Introduction This Construction Environmental Management Plan (CEMP) details the requirements for the management of environmental impacts during the construction phase of works for the Central Processing Facility (CPF), as part of the Gloucester Gas Project (the Project) (refer to Figure 1.1), being completed by AGL Energy Limited (AGL). Separate CEMPs have been developed for the purposes of environmental management for the three separate construction areas of the Project, namely: • the Stage 1 Gas Field Development Area (GFDA) (refer to Figure 1.2), which is a series

of 110 gas wells to be installed for the collection of gas. The construction of the gas wells includes construction of a series of gas and water gathering pipelines, connecting the Stage 1 GFDA to the CPF;

• the CPF, which processes collected gas from the GFDA gas field wells, prior to distribution to the gas pipeline. Further information on the construction process is provided in Section 2.0; and

• the gas delivery pipeline, the pipeline delivering gas from the CPF to the delivery point at the Newcastle Gas Storage Facility (NGSF) located at Tomago.

1.1 Purpose and Scope

The purpose of this CEMP is to provide a description of the measures to be implemented by AGL and/or contractors and subcontractors of AGL to manage environmental impacts associated with the construction of the CPF. This CEMP also details the environmental monitoring requirements associated with construction and provides a mechanism for assessing environmental monitoring results against the relevant criteria from the Gloucester Gas Project Environmental Assessment (EA, AECOM 2009). This CEMP addresses the requirements detailed in Condition 7.2 of the Project Approval (PA 08_0154) relating to the construction of the CPF only. A brief outline of the Project Approval conditions relevant to this CEMP is provided in Section 2.1, including a checklist of where each condition has been addressed within this plan. 1.2 Objectives

This CEMP has been developed to outline environmental management practices and procedures to be followed during construction of the CPF to protect the environment and achieve compliance with the requirements of the Project Approval. The objectives of this CEMP are to: • minimise and control the impact of construction activities on the environment;

• achieve compliance with regulatory and AGL environmental requirements; and

• define the roles and responsibilities and actions that are required to respond to environmental incidents.

These objectives will be achieved by: • incorporating environmental requirements in project design criteria and construction

plans;

Umwelt (Australia) Pty Limited 3325/R08/V3 January 2015 1

Gloucester Gas Project DRAFT Introduction Central Processing Facility Construction Environmental Management Plan • raising AGL and contractor awareness of, and monitoring compliance with, on-site and

off-site environmental requirements;

• providing regular overview and auditing of design and construction activities to achieve environmental performance and compliance;

• preparation of aspect specific management plans (where required) associated with construction activities in accordance with Condition 7.2 of PA 08_0154;

• the use of specific tools and activities, such as:

employee and contractor environmental awareness training during inductions, toolbox, pre-starts, daily information sheets, etc.;

site environmental inspections and audits;

environmental monitoring;

environmental incident response action plans;

incident reporting, including analysing of cause and corrective actions to rectify reoccurrence;

non-conformance reporting with actions to rectify and close out; and

environmental requirements to be included in contractor EMPs, work method statements, etc.

1.3 CEMP Structure

This CEMP is the overarching AGL environmental management document for the CPF and describes the systems for minimising and managing environmental risks associated with construction activities (refer to Figure 1.3). The CEMP has been prepared in accordance with the EA (including Statement of Commitments), relevant legislation and the conditions of PA 08_0154 and is comprised of the following sections: Sections 1.0 to 3.0 – Introduction including purpose and scope, CEMP structure, risk management, description of CPF construction activities, and regulatory requirements. Sections 4.0 to 6.0 – Details the management, mitigation and monitoring for noise (including vibration and blasting), dust and traffic. Section 7.0 – Details the reporting requirements for the construction of the CPF. Section 8.0 – Describes the review process for this CEMP. Section 9.0 – Contains accountabilities in relation to this CEMP. Section 10.0 – Contains abbreviations and glossary. The CEMP includes issue specific management sub plans as appendices, in accordance with Condition 7.2 of PA 08_0154 to meet the requirements of the EA, Statement of Commitments and applicable legislation relevant to the specific environmental aspect. Construction activities relating to the CPF will be undertaken in accordance with the CEMP and sub plans. The sub plans attached to this CEMP include: • Flora and Fauna Management Plan (Appendix 1);


Gloucester Gas Project DRAFT Introduction Central Processing Facility Construction Environmental Management Plan • Aboriginal Heritage Management Plan (Appendix 2);

• Soil and Water Management Plan (Appendix 3);

• Waste Management Plan (Appendix 4); and

• Landscape and Rehabilitation Management Plan (Appendix 5).

The Project Approval required a number of additional management plans to be prepared, which do not fall under this CEMP. The following management plans will be prepared separately: • Field Development Plan for the Stage 1 Gas Field Development Area;

• Extracted Water Management Strategy;

• Temporary Construction Facilities Management Strategy (further discussed in Section 2.3); and

• Community and Stakeholder Engagement Plan.

1.4 Environmental Risk and Management Requirements

A Risk Assessment and Preliminary Hazard Analysis were undertaken as part of the EA. As part of the Risk Assessment, an analysis was undertaken whereby the highest risks were identified for detailed assessment. The Preliminary Hazard Analysis identified the hazards and consequences and therefore the identified risks for the Project. This CEMP has been developed in the context of the identified environmental risks from these two assessments (refer to Section 8 and Appendix I of the EA). A number of management actions were identified for the construction phase of works for the CPF. These management actions have been incorporated into this plan where relevant. Sections 4.0, 5.0 and 6.0 of this plan, along with the management control sections of the appendices attached to this plan, provide management actions to be utilised during the construction phase of works for the CPF. Further management actions may be required, based on the outcomes of additional surveys that will be completed prior to the commencement of construction. If additional management actions are required as a result of these surveys, these actions will be incorporated into future reviews of this plan and appendices.


Gloucester Gas Project – Stage 1 DRAFT Stage 1 CPF Construction Activities Central Processing Facility Construction Environmental Management Plan

2.0 CPF Construction Activities

2.1 The CPF

As part of the EA, two separate conceptual CPF locations were identified. AGL has identified the proposed CPF location no. 7 as the preferred option for construction and as such CPF location no. 7 is the location detailed below. The approximate location for the CPF is shown on Figure 1.2. The construction of the CPF involves the construction of a facility with a capacity of up to 80 terajoules (TJ) per day to treat and compress gas produced within the GFDA to render it suitable for high pressure transport via the gas delivery pipeline. The following infrastructure items are proposed to be constructed for the CPF: • administration and plant control room;

• a water treatment facility for removal of oil-in-water emulsion from the process water caused by the compression process;

• a water treatment facility for desalination of produced water;

• up to eight compressor units and associated plant for compression and dehydration of gas;

• gas dehydration equipment;

• gas filtration, regulation, metering and analysis equipment;

• start, instrument and fuel gas filtration, regulation and metering equipment;

• flaring system;

• network of storage and evaporation ponds;

• small scale ancillary power generation with a capacity of up to 15 megawatts (MW) [Future]; and

• laydown areas for the storage of pipe and equipment.

The CPF would also process gas to remove impurities such as coal fines and free water. The CPF footprint would incorporate a water treatment facility, which would include a water treatment plant and three storage ponds of up to 25 megalitres (ML) capacity each to store produced water, treated water and the brine waste water respectively. 2.1.1 Ancillary Power Generation Facility

A small scale ancillary power generation facility is proposed within the CPF footprint. The ancillary power generation facility would comprise up to five 3 MW power generator units, with a total capacity of up to 15 MW. The power generator units would be gas-fired generators that would be driven by gas produced by the GFDA and be used for the CPF to provide power to plant such as the Water Treatment Facility.


Gloucester Gas Project – Stage 1 DRAFT Stage 1 CPF Construction Activities Central Processing Facility Construction Environmental Management Plan 2.1.2 CPF Construction Location Rules

While the locality of the CPF has been confirmed as CPF no. 7 from the EA, in accordance with Statement of Commitments Condition 4, AGL will ensure that the location of infrastructure for the CPF and other ancillary facilities associated with the CPF minimises environmental impact and the locations are selected generally in line with the disturbance rules outlined below. The disturbance footprint of the CPF will be located to avoid remnant vegetation patches and at least 40 metres (m) from major watercourses. 2.2 Construction Hours

Construction activities will be undertaken in accordance with the requirements of Project Approval Conditions 3.14 to 3.16. Details of the construction hours proposed are provided in Section 4.2. 2.3 Temporary Construction Workforce Camp

As required by Condition 3.54 of PA 08_0154, AGL will prepare a Temporary Construction Facilities Management Strategy, which will detail information in relation to the temporary construction workforce camp, including: • the final location of construction workforce camps;

• details of construction material sourcing (including gravel and water requirements) as per Condition 7.2c of PA 08_0154;

• the scale and dimension of facilities;

• utility and service requirements;

• management measures and protocols that will be implemented on site (including behavioural management); and

• detailed decommissioning and rehabilitation requirements at the cessation of the construction period.

2.4 Materials Sourcing

2.4.1 Gravel/Roadbase

There are two substantial gravel quarries in close proximity to the Project, with one located on The Bucketts Way in the Gloucester area and one at Nabiac. It is anticipated that gravel will likely be provided by these two quarries depending upon product specifications meeting AGL’s needs.


Gloucester Gas Project – Stage 1 DRAFT Stage 1 CPF Construction Activities Central Processing Facility Construction Environmental Management Plan 2.5 Potential for Cumulative Impacts

Impacts associated with the construction of the CPF have been outlined in Sections 4.0 to 6.0 and Appendices 1 to 5 of this CEMP, with measures to manage and/or mitigate potential impacts outlined in each applicable section. The potential for cumulative impacts would likely result from the CPF construction and the operation of the Stratford Mining Complex (SMC), located in the vicinity of the proposed CPF. Yancoal operates the SMC and is required to undertake meteorological, air quality, surface water, groundwater, vibration and airblast, and noise monitoring. Review of the Stratford Coal Annual Review for 2013, covering the reporting period from 1 July 2012 to 30 June 2013, provides a summary of the key issues for local residents in the area as evidenced by complaints received during the reporting period. Key issues include: • noise;

• blasting;

• air quality;

• train;

• water;

• lighting;

• traffic safety;

• traffic movement;

• ground surface damage; and

• visual.

Potential cumulative impacts resulting from construction of the CPF and the operation of the SMC are likely to be in relation to noise, air quality and traffic related impacts. Cumulative impacts for each environmental factor were considered in the EA for the Project, with the EA concluding the potential impacts would be acceptable provided the prescribed management and/or mitigation measures and safeguards (outlined in Sections 4.0 to 6.0 and Appendices 1 to 5 of these CEMP) are implemented. Furthermore, as the construction phase is short-term, any cumulative impacts associated with construction of the CPF would be temporary. AGL is committed to managing and/or mitigating the impacts associated with construction of the CPF (refer to Sections 4.0, 5.0 and 6.0) and will work in consultation with Stratford Coal to enable proactive management of the construction of the CPF and the operation of the SMC to reduce potential cumulative impacts to the surrounding environment and community. Potential cumulative impacts associated with the operation of the CPF will be addressed in the operational management plan.

Gloucester Gas Project – Stage 1 DRAFT Noise Management Central Processing Facility Construction Environmental Management Plan

4.0 Noise Management This section outlines the environmental management activities and controls, for potential noise impacts, to be implemented during construction activities associated with the CPF. Sections 4.4 and 4.5 outline the mitigation and monitoring measures to be undertaken during the construction phase of the CPF for noise impacts. 4.1 Existing Environment

The Gloucester area is rural in nature, with landuse including improved and semi-improved pasture, agricultural activities including dairying, beef cattle production, and some cultivation. Ambient noise levels within the Gloucester Area are influenced by farming landuses, bird noise and domestic noise sources as well as noise from mining sources. 4.2 Construction Hours

In accordance with Condition 3.14 of PA 08_0154, audible works at the nearest sensitive receptors associated with construction of the CPF will only be undertaken during the following hours: • 7.00 am to 6.00 pm Monday to Fridays;

• 8.00 am to 1.00 pm Saturdays; and

• no audible construction works to be undertaken on Sundays or public holidays.

These hours may be varied in the event of a direction from police or other relevant authority for safety reasons or emergency work to avoid the loss of lives, property and/or to prevent environmental harm. In accordance with condition 3.16 of PA 08_0154, where variation of the construction hours is required, written approval will be obtained from the Secretary of the DP&E. Any request to alter the construction hours shall be: • considered on a case by case basis;

• accompanied by details of the nature and need for activities to be conducted during the varied construction hours including the alternatives considered;

• accompanied by details of all reasonable and feasible measures identified to minimise noise impact at nearest sensitive receivers;

• accompanied by details of consultation and notification undertaken with surrounding receptors (including, in respect to proposed gas drilling works on a 24 hour basis – written agreement from affected landowners, where relevant construction noise goals are not expected to be achieved); and

• accompanied by written evidence demonstrating consultation with the EPA in relation to the proposed variation in construction times (including consideration of any comments made by the EPA).

+ These noise targets are based on the lowest assessable levels under the NSW Industrial Noise Policy (DECC 2000), further background monitoring is recommended to be undertaken to develop specific noise goals for any other properties that are considered to be affected as a result of the construction of the final locations of the gas wells.


Gloucester Gas Project – Stage 1 DRAFT Noise Management Central Processing Facility Construction Environmental Management Plan At the commencement of construction one noise monitoring event will be undertaken during construction at sensitive receptors located within 250 m of the CPF and monitoring to cease after three monitoring events determine noise levels to be within the range of predicted noise levels. Moreover, in accordance with the Interim Construction Noise Guideline (ICNG) and management measures outlined in this CEMP, noise monitoring will be undertaken following receipt of any compliant from nearby residents. 4.5 Predicted Impacts

The construction of the CPF would involve a number of potential noise generating activities including: • site preparation;

• foundation preparation;

• concrete pouring;

• erection of structures;

• installation of plant and surface facilities;

• testing and pre-commissioning; and

• site clean up.

Construction of the CPF would be undertaken over an approximately 12 month period. Hours of work would be in accordance with Section 4.2. The CPF construction would require delivery of construction plant and materials to the site prior to construction which would represent the main traffic volumes in respect of the CPF facility. The CPF construction would also generate some 36 light vehicle movements per day over the anticipated construction period of 12 months, although traffic would be staggered to reflect the construction program. Noise modelling for traffic from the Project assumed a worst case scenario, being that construction activities could generate up to 30-40 car movements per hour with 10% heavy vehicles. With an average pass-by traffic speed of 50 km/h, the predicted LAeq 1 hour at 30 metres of 51 dBA satisfies the daytime 55/60 dBA target noise assessment goals for local and collector roads, respectively (AECOM 2009). Predicted noise levels resulting from the CPF construction activities, relative to the distance from the construction works are shown in Table 4.3 below.

Table 4.3 – Predicted Noise Levels (dBA) from Construction Activities – Stage 1 CPF

Gloucester Gas Project – Stage 1 DRAFT Noise Management Central Processing Facility Construction Environmental Management Plan As shown in the table above, the modelling results indicate that noise levels during construction activities associated with the CPF would exceed the construction noise target goals at some residential properties without secondary noise controls, depending on the relative distance to the activity. 4.6 Noise Management Controls

The following management measures have been prepared in respect of the construction of the CPF to address construction noise, and methods to minimise impacts. In accordance with Condition 3.17 of PA 08_0154, AGL will implement all reasonable and feasible measures to minimise noise generation from the construction of the CPF, consistent with the requirements of the Interim Construction Noise Guideline (DECC 2009) including noise generated by heavy vehicle haulage and other construction traffic associated with the CPF. The following management measures will be undertaken to manage construction related noise impacts as a result of the construction of the CPF: • selection of plant and equipment where practical on acoustic performance;

• work practices to be implemented to minimise potential noise and vibration impacts, this may include (ICNG 2009):

where practical, undertake the noisiest works during the recommended standard hours;

turn off plant that is not being used;

examine, and implement where feasible and reasonable, alternative work practices which generate less noise – for example, use hydraulic rock splitters instead of rock breakers, or electric equipment instead of diesel or petrol powered equipment;

examine, and implement where feasible and reasonable, the use of silenced equipment and noise shielding around stationary plant (such as generators), subject to manufacturers’ design requirements;

ensure plant is regularly maintained, and repair or replace equipment that becomes noisy;

arrange the work site to minimise the use of movement alarms on vehicles and mobile plant; and

locate noisy plant away from potentially noise affected neighbours or behind barriers, such as sheds or walls;

• a monitoring program to ensure that construction noise emissions are controlled and that the best possible practices are implemented;

• noise monitoring shall be conducted in response to community complaints and at the request of the EPA. Reports of investigations shall be provided to the EPA upon request. In addition, complaints will be handled in a prompt and responsive manner and staff responsible for handling complaints shall be informed in current and upcoming works;

• site noise training and awareness program for all staff and contractors engaged during construction. This program will include aspects of noise management such as (DECC 2009):

avoid dropping materials from a height;

tool box talks regarding noise from the works at the identified land uses and how it can be reduced; and


Gloucester Gas Project – Stage 1 DRAFT Noise Management Central Processing Facility Construction Environmental Management Plan use of radios and stereos indoors rather than outdoors;

• development and implementation of a public relations program to inform residents and the community of the progress of activities and potential noise impacts and noise management measures for each phase of the Project. In accordance with the Interim Construction Noise Guide (DECC 2009) the public relations program will allow for:

contacting potentially noise affected neighbours at the earliest possible time before any site work begins;

informing potentially noise affected neighbours about the nature of the construction stages and the duration of noisier activities – for example, excavation and rock-breaking;

describing any noise controls, or use of silenced equipment;

keeping potentially noise affected neighbours up to date on progress;

providing contact details on a site board at the front of the site, and maintain a complaints register suited to the scale of works (refer to Section 7.2); and

asking about any concerns that potentially noise affected neighbours may have and discussing possible solutions;

• the establishment of procedures to address noise and vibration complaints received from the public during the construction period (refer to Section 7.2);

• implement a targeted risk based noise monitoring program focussed on the highest risk noise generating construction activities undertaken in proximity (i.e. approximately 250 m) to sensitive receiver areas as detailed further in Section 4.7; and

• construction traffic noise will be managed through the transport code of conduct (refer to Section 6.4).

Additional Mitigation and Management Measures After the application of reasonable and feasible mitigation measures (as outlined above), if the predicted construction noise goals cannot be met, AGL will provide additional management measures to minimise noise impacts on affected receivers. Table 4.4 outlines a number of additional actions and construction noise management measures that may be implemented through the construction phase.

4.7 Noise Monitoring

Construction noise monitoring conditions are not included in PA 08_0154. As outlined in Section 4.5, AGL is committed to the management and mitigation of potential noise impacts that result from the CPF construction. In addition, inspections will be undertaken by the Construction Manager to ensure that the management requirements of Section 4.5 are being met. Noise complaints will be managed as per the process outlined in Section 7.2. In addition to the process outlined in Section 7.2, data regarding the meteorological information (i.e. Bureau of Meteorology website information) and works completed during the time of complaint will be collected. Non-compliances will be managed as per the process outlined in Section 7.3.


Gloucester Gas Project – Stage 1 DRAFT Dust Management Central Processing Facility Construction Environmental Management Plan

5.0 Dust Management This section outlines the environmental management activities and controls, for potential dust related impacts, to be implemented during construction activities in the CPF. As outlined in Section 9.4.2 of the EA, the location of the CPF and low number and density of surrounding receptors means that there is little potential for dust and exhaust emissions to give rise to nuisance impacts off-site, provided the works are undertaken with appropriate dust mitigation and management measures. The following sections outline the mitigation and management measures to be undertaken during the construction phase of the CPF for dust related impacts. 5.1 Existing Environment

Air quality in the Gloucester basin is influenced predominantly by agricultural emissions with lesser contributions from coal mining operations and vehicular traffic moving along The Bucketts Way. 5.2 Predicted Impacts

Potential emissions to air associated with the construction phase of the CPF include typical construction emissions such as dust from soil excavation and handling activities and site clearance works. Other emissions include exhaust emissions (products of combustion) from construction equipment. 5.3 Air Quality Management Controls

The construction safeguards for the CPF to minimise dust and vehicle emissions during the construction include: • controlling access via gravelled roadways for private access roads to the CPF area;

• setting vehicle speed limits on site for access to the CPF. A transport code of conduct is required as part of traffic management (refer to Section 6.4) which will outline the required speed limits for the CPF;

• monitoring wind speed and direction to manage dust-generating activities during undesirable conditions. This will be undertaken via review of forecasted weather conditions via publicly available information sources (such as the Bureau of Meteorology website). The requirement for additional controls such as the use of water carts will be determined by considering dust generating activities, forecast weather conditions and visual observations;

• minimising areas of disturbance during construction to the minimum area required (refer to Section 2.0);

• stockpiling of soils on site kept to a minimum;

• undertaking progressive rehabilitation of disturbed areas wherever feasible, as soon as practicable following disturbance;


Gloucester Gas Project – Stage 1 DRAFT Dust Management Central Processing Facility Construction Environmental Management Plan • inspecting and maintaining construction equipment regularly to minimise exhaust

emissions and ensure appropriate working condition;

• conducting visual assessment of air emissions on a routine basis; and

• managing complaints received in accordance with the process outlined in Section 7.2 and Section 7.3.

5.4 Dust Monitoring

The Construction Manager will be responsible for the implementation of mitigation measures to reduce the potential dust related impacts resulting from the CPF construction activities. Dust complaints will be managed as per the process outlined in Section 7.2. In addition to the process outlined in Section 7.2, data regarding the meteorological information (i.e. Bureau of Meteorology website information) and works completed during the time of complaint will be collected. Non-compliances will be managed as per the process outlined in Section 7.3.


Gloucester Gas Project – Stage 1 DRAFT Traffic Management Central Processing Facility Construction Environmental Management Plan

6.0 Traffic Management This section outlines the environmental management activities and controls for potential traffic and transport related impacts, to be implemented during construction activities for the CPF. Sections 6.4 and 6.5 outline the mitigation and management measures to be undertaken during the construction phase of the CPF for traffic and transport related impacts. 6.1 Existing Environment

The CPF is located approximately 100 kilometres north of Newcastle in the Gloucester Local Government Area (LGA). The only major roadway servicing the CPF is The Bucketts Way (MR90), which has an average annual daily traffic (AADT) volume of approximately 4095 at Gloucester and 1555 south of Stratford; this road is classified as a Collector Road (i.e. those with an AADT volume of between 2000 to 10,000). 6.2 Predicted Impacts

Access to the CPF would likely be through the adjacent property to the south of Parkers Road from The Bucketts Way. This is due to the limited sight distances to access Parkers Road from The Bucketts Way (AECOM 2009). An intersection upgrade would occur as part of the Project and will involve widening the road at the proposed intersection on The Bucketts Way, and inclusion of a channelized right turn lane to provide a protected right hand turn onto the proposed access road for the CPF. The majority of construction traffic movements for the CPF construction components will occur over a limited period (approximately 30 days) during the initial delivery of plant, equipment and materials to the construction site. Once initial delivery has taken place, additional traffic movements generated on the external road network will be temporary for a period of 18 months to 5 years during the construction phase of the CPF, with 18 months representing the most intense construction period and therefore a worst case scenario (AECOM 2009). Additional traffic movements on public roadways will be primarily related to the transportation of gravel (refer to Section 2.4.1) associated with well pad and road construction as part of the GFDA, in addition to deliveries required on a daily basis and personnel travel. The regional and local roadways that are anticipated to experience the greatest impacts as a result of the CPF are The Bucketts Way (MR90) and Parkers Road, which will be the primary access routes for these deliveries. The EA traffic assessment identified that the existing traffic volumes for the identified roads are within operational criteria, and capacity is available for the proposed temporary increase (AECOM 2009). However, impacts will require management through implementation of the management measures outlined in Section 6.4 below. The majority of the workforce for the CPF is anticipated to be accommodated in a construction workforce camp and will be transported to the worksite by minibus, thereby minimising traffic impacts. Management controls specific to traffic impacts as a result of the temporary construction facilities will be outlined in the Temporary Construction Facilities Management Strategy.


Gloucester Gas Project – Stage 1 DRAFT Traffic Management Central Processing Facility Construction Environmental Management Plan 6.3 Plant and Equipment

Construction plant and equipment will be delivered to the CPF site at the commencement of construction works, and would typically include the following: • 1 x bulldozer;

• 2 x graders;

• 2 x rollers;

• 2 x excavators;

• 2 x bobcats;

• 1 x piling rig;

• 2 x tip trucks (for transporting imported fill and base course material);

• welding machinery;

• electric generators for construction equipment;

• 4 x cranes for heavy lifts;

• 1 x cranes for small lifts;

• 1 x franner for pipe spool placement; and

• 1 x forklift for moving equipment.

Where possible it is anticipated that the plant components of the CPF would be delivered to the Port of Newcastle and transported via road as prefabricated units with assembly undertaken on the site. Various pipe work, electrical and miscellaneous equipment would also be delivered to site for the assembly stage. The CPF construction would require delivery of construction plant and materials to the site prior to construction which would represent the main traffic volumes in respect of the CPF. The CPF construction would also generate some 36 light vehicle movements per day over the anticipated construction period of 12 months although traffic would be staggered to reflect the construction program. 6.4 Traffic Management Controls

The construction phase will result in the greatest increase in traffic in the vicinity of the CPF as a result of deliveries of plant, equipment and materials, personnel transport and construction activities. Management measures to be implemented to minimise potential impacts to the surrounding road network include: • a Transport Code of Conduct will be completed by the construction contractor and will

broadly include the following:

identification of construction traffic routes;

the location of designated entry and exit routes;


Gloucester Gas Project – Stage 1 DRAFT Traffic Management Central Processing Facility Construction Environmental Management Plan heavy vehicle access routes to the various laydown areas and temporary construction

facilities;

deliveries and dispatch during construction and operation;

heavy vehicle parking during construction and operation;

internal speed limits;

use of truck turnaround areas;

access to laydown and temporary work areas;

details of road/intersection upgrades; and

a traffic monitoring program to control and measure compliance with the Transport Code of Conduct;

• consultation to be undertaken with potentially affected landowners and relevant road authorities with regard to the timing of plant and equipment delivery campaigns and potential localised impacts on the road network;

• where oversized vehicles are used, suitable controls and management will be implemented and heavy vehicle permits will be obtained as required. Oversized loads will be transported in accordance with relevant NSW Roads and Maritime Services (RMS) guidelines;

• heavy vehicle movements will be scheduled wherever possible to avoid or minimise localised impacts such as avoiding peak traffic zones and school zones between the hours of 7.00 am to 9.00 am and 2.00 pm to 4.00 pm;

• the internal CPF road network and pipeline right of way (ROW) will be used to facilitate access and accommodate vehicle movements wherever possible;

• AGL will prepare pre and post dilapidation reports for major access roads affected by the CPF. Impacts considered to be attributable to the construction of the CPF, as determined by the dilapidation reports, will be remediated following construction. The requirements for the road dilapidation reports are outlined in Condition 3.44 and 3.45 of the Project Approval;

• vehicle movements will be minimised wherever possible;

• materials will be sourced from local suppliers where possible;

• nominated transport routes will be identified in future revisions of this CEMP;

• contractors will be made aware of the requirements to use the nominated transport routes when travelling to and from the CPF, through the pre-work induction process and training process;

• temporary road closures, if required, will be undertaken with the approval of the applicable authorities, and in accordance with any specific requirements;

• power line management, if required for oversized loads, will be undertaken in consultation with the infrastructure owner, and in accordance with any specific requirements; and

• work method statements are to be completed for all heavy vehicle and oversize loads being transported to the CPF to identify hazards and controls to manage the associated risks.


Gloucester Gas Project – Stage 1 DRAFT Traffic Management Central Processing Facility Construction Environmental Management Plan 6.5 Traffic Monitoring

As outlined in Section 6.4, AGL is committed to the management and mitigation of potential traffic and transport related impacts from the CPF construction. The Transport Code of Conduct to be completed by the construction contractor/s will include a monitoring program to measure compliance with the requirements of the Transport Code of Conduct. In addition, the Construction Manager will be responsible for ensuring regular inspections are undertaken so that the management requirements of Section 6.4 are being met. Traffic complaints will be managed as per the process outlined in Section 7.2. Non-compliances will be managed as per the process outlined in Section 7.3. 6.6 Agency Consultation

Prior to the commencement of construction of the CPF, specific agency consultation will be undertaken with local councils and RMS regarding traffic management measures and monitoring in accordance with Condition 7.2(g)iii in order to receive feedback on the proposed construction routes and traffic management techniques identified for the CPF. Feedback received from this consultation would be incorporated into the Traffic Code of Conduct and/or this CEMP.


Gloucester Gas Project – Stage 1 DRAFT Review Central Processing Facility Construction Environmental Management Plan

7.0 Reporting

7.1 Exceedance Reporting Protocol

Exceedances of relevant criteria will be classified as environmental incidents and will be managed in accordance AGL’s internal incident management system (myHSE). In accordance with this procedure, environmental incidents will be investigated to a level commensurate to their risk level, in consultation with the AGL Gloucester Gas Project Environmental Representative. Additional controls will be implemented where required, based on the outcomes of the investigation. Exceedances of Environment Protection Licence (EPL) criteria will be reported in the EPL Annual Return. Incidents that have caused, or threaten to cause material harm to the environment will be reported to the appropriate regulatory authority immediately after AGL becomes aware of the incident in accordance with Section 148 of the Protection of the Environment Operations Act 1997. 7.2 Complaint Response

The construction contractor will maintain a 24 hour community complaints line during the construction of the CPF that will be available throughout the construction activities. Records of all community complaints will be maintained on an up-to-date Complaints Register in accordance with Condition 6.3 of PA 08_0154. The records will include: • date and time of the complaint;

• the means by which the complaint was made (telephone, mail or email);

• any personal details of the complainant that were provided, or if no details are provided, a note to that effect;

• the nature of the complaint;

• any actions taken by AGL/construction contractor in relation to the complaint, including any follow up contact with the complainant and the timing for implementing action; and

• if no action was taken by AGL/construction contractor in relation to the complaint, the reason why no action was taken.

Community complaints will be allocated to a responsible AGL employee immediately to facilitate the implementation of corrective actions. The details of the complaint will also be circulated to the applicable construction personnel for action, where required. A summary of complaints will be made available to regulatory authorities and the community on request by the DP&E in accordance with Condition 6.3 of PA 08_0154. 7.3 Corrective Actions

An environmental non-compliance can occur as a result of exceedance of performance criteria outlined in the EPL or Project Approval and/or any notice of non-compliance issued by a regulatory authority with environmental jurisdiction. Environmental non-compliances may also be detected through verification processes such as monitoring, inspections, audits and receipt of complaints.


Gloucester Gas Project – Stage 1 DRAFT Review Central Processing Facility Construction Environmental Management Plan AGL will identify any environmental non-compliance (including environmental incidents) during construction and will undertake the required corrective actions to address the non-compliance and implement preventative actions where required. Tracking of environmental non-compliances and associated corrective actions will be through AGL’s compliance system and administered by the compliance management team: • a preliminary review of the nature of the non-compliance will be conducted;

• an investigation will be commissioned into the non-compliance to confirm the cause and effect, and any relevant options to the management of potential impacts or prevention of further impacts (as appropriate);

• an assessment will be made of whether the non-compliance requires reporting to relevant stakeholders;

• preparation of an action plan, in consultation with the relevant agency stakeholders (if required); and

• if necessary, implementation of additional monitoring to measure the effectiveness of the controls implemented.

7.4 Environmental Emergency Contact and Response

AGL is committed to establishing and maintaining a work place that minimises hazards to human health and the environment including emergency situations (e.g. fires, explosions, unplanned material or liquid releases). Moreover, AGL has an environmental incident response plan and an overarching emergency response plan.
