6 Traffic Management Sub Plan EN-PL INTRODUCTION AGL Energy Limited (AGL) is developing the Newcastle Gas Storage Facility Project in Tomago and Hexham, New South Wales. The Project is required to meet AGL s peak gas market requirements over winter and to provide additional security of gas supply during supply disruption events. New South Wales currently has no reliable gas storage capacity. The development includes the following components: Gas storage facility site; Access road and utility corridor; Gas pipeline access corridor; Pipeline corridor including temporary construction areas; Hexham receiving station; and Gas pipeline connection to the existing Jemena Gate Station at Hexham. 1.1 Purpose and Scope This Traffic Management Sub Plan (TMP) forms part of the Construction Environmental Management Plan for CBI s portion of the development (the Project) to construct the following components: Gas storage facility site; Access road and utility corridor; and Gas pipeline access corridor. The purpose of this TMP is to describe how CBI proposes to manage traffic during construction. This Plan has been prepared to address the requirements of the Minister s Conditions of Approval (CoA), the AGL Statement of Commitments (SoC), the safeguards listed in the Environmental Assessment (EA) and Preferred Project and Response to Submissions Report (PPR), and all applicable legislation. 1.2 Background The EA assessed traffic impacts during the construction of the Project. Details of the assessment methodology and outcomes of traffic modelling and analysis were provided in Volume 4 Appendix 12 referenced below. AECOM Traffic Study Newcastle Gas Storage Facility Project 13 April 2011 The Tomago area is served by the local road network that includes Old Punt Road and Tomago Road. The Pacific Highway runs north-south at the west of Tomago. The EA found that movement of construction materials, personnel and equipment will increase light and heavy vehicle traffic in the area during construction. Some local traffic may be affected for short periods during the movement of oversize loads. During construction, there will be a temporary increase in traffic volumes on all roads in the vicinity of the Project The routes to be used by construction vehicles already carry a high proportion of commercial/heavy vehicles. Given the existing industrial nature of the area surrounding the Project, the consequence of a change in traffic volume and composition will be minor. 1.3 Objectives The key objective of this Plan is to avoid or minimise potential adverse traffic impacts to the environment and community. To achieve this objective, CBI will undertake the following: Ensure appropriate environmental controls and procedures are implemented during construction to minimise traffic impacts to the environment and all sensitive receivers; Ensure appropriate measures are implemented to address CoA outlined in Table 1.3; Ensure appropriate measures are implemented to address SoC outlined in Table 1.4 and the controls detailed in the EA; and Uncontrolled if Printed Issue Date: 22 April 2013 Page 6 of 38

7 Traffic Management Sub Plan EN-PL Ensure appropriate measures are implemented to comply with all relevant legislation and other requirements described in Section 1.5 and Section 1.6 of this Plan. 1.4 Environmental Management Systems Overview The overall Environmental Management System for the Project is described in the Construction Environmental Management Plan (CEMP). The TMP is part of the CBI environmental management suite of documents for the Project, as described in Section 4.3 of the CEMP. Management measures identified in this Plan will be incorporated into site or activity specific Environmental Work Method Statements (EWMS). EWMS will be developed and signed off by environment and management representatives prior to associated works and construction personnel will be required to undertake works in accordance with the identified controls. Used together, the CEMP, sub plans, procedures and EWMS form management guides that clearly identify required environmental management actions for reference by CBI personnel and contractors. The review and document control processes for this Plan are described in Section 4.4, Section 4.5 and Section of the CEMP. 1.5 Relevant Legislative Requirements and Guidelines Legislation Legislation relevant to the management of traffic for the Project is presented in Table 1-1 below. Table 1-1: Key Legislative and Regulatory Requirements Legislation / Policy NSW Environmental Planning and Assessment Act 1979 (EP&A Act) Protection of the Environment Operations Act 1997 (POEO Act) State Environmental Planning Policy (Infrastructure) 2007 Relevance The EP&A Act and Regulation include provisions to ensure that proposals which have the potential to impact the environment are subject to detailed assessment, and provide opportunity for public involvement. The EP&A Act requires compliance with the conditions of the project approval granted for the Project under Part 3A of the EP&A Act. Construction of the Project will be undertaken in accordance with the POEO Act, which covers a range of environmental offences including noise generation. Specifically Part 5.5 of the Act details noise pollution offences and requirements for the proper and efficient operation, maintenance and handling of plant, equipment and materials. The State Environmental Planning Policy (Infrastructure) 2007 (Infrastructure SEPP) aims to provide a consistent planning regime for infrastructure and the provision of services across NSW, along with requiring consultation with relevant public authorities during the assessment process. Clause 104 of the Infrastructure SEPP requires certain traffic-generating development to be referred to the Roads and Traffic Authority (RTA) for comment. Schedule 3 identifies the type of development to which the clause applies. The Project is classified as any other purpose development in Schedule 3 and, accordingly, clause 104 will apply, as the Project will generate more than 200 vehicles during construction and operation phases. Consultation with the RTA has been on-going during the EA process. Uncontrolled if Printed Issue Date: 22 April 2013 Page 7 of 38

8 Traffic Management Sub Plan EN-PL Legislation / Policy Relevance NSW Road Noise Policy The NSW Road Noise Policy replaced the Environmental Criteria for Road Traffic Noise from 1 July The NSW Road Noise Policy contains strategies to address the issue of road traffic noise from: existing roads new road projects road redevelopment projects traffic generating developments. The policy also defines criteria to be used in assessing the impact of road traffic noise. It is intended for use by: road project proponents determining authorities and regulators city and transport planners acoustic specialists. The policy aims to: facilitate a more streamlined assessment process for road projects increase protection for residents in quiet areas experiencing large increases in noise from road projects provide up-to-date guidance on strategies to minimise road traffic noise. 1.6 Guidelines The following guidelines relevant to traffic management were considered in the development of this Plan. Traffic Control at Worksites Version 4 RTA The purpose of the manual is to maximise safety by ensuring that traffic control at work sites consistently complies with best practice. It is also intended to help personnel comply with OHS Act and Regulations. Guidelines for Emergency Vehicle Access Policy No 4 (NSW Fire Brigades, 2010) The guideline is used as a reference for developers and planners to ensure the NSWFB emergency vehicles can adequately access sites, buildings and structures in the event of an emergency (e.g. fire or explosion). During an emergency, the NSWFB is the most efficient and suitable provision for rapid and unhindered response by its emergency vehicles. Poor or inadequate access can result in a delayed NSWFB response, with the obvious delay to the intervention having a direct impact on the life and safety of occupants and the protection of property. RTA Guide to Traffic Generating Developments The RTAs Guide to Traffic Generating Developments outlines all aspects of traffic generation considerations relating to developments. The information provided gives background into the likely impacts of traffic from various types of development. The guide provides a section on various land use traffic generation and a section on interpretation of traffic impacts. The impact on traffic efficiency at intersections is used in this study and intersection performance is based on the level of service criteria for intersections shown in Table 1-2. Table 1-2: Level of Service Criteria for Intersections Level of Service Average Delay (secs/ veh) Traffic Signals and Roundabouts Give Way and Stop Signs A Less than 14 Good operation Good operation B 15 to 28 Good with acceptable delays and spare capacity Acceptable delays and spare capacity C 29 to 42 Satisfactory Satisfactory, but accident study required D 43 to 56 Operating near capacity Near capacity and accident study required E 57 to 70 At capacity; at signals incidents will cause excessive delays At capacity; requires other control mode Uncontrolled if Printed Issue Date: 22 April 2013 Page 8 of 38

9 Traffic Management Sub Plan EN-PL F > 70 Roundabouts require other control mode At capacity; requires other control mode Source: Guide to Traffic Generating Developments: Version 2.2, RTA October 2002 RTA Road Design Guide The RTA Road Design Guide provides guidelines to ensure that there is a consistent approach to road design by the Authority. The guide provides information on basic design criteria, road geometry, cross sections, and intersections at grade, safety barriers for roads and bridges and drainage. For this Plan, guidelines on intersections at grade have been consulted. Intersections at grade provides details on the planning and design procedure to be followed, and the details necessary to develop a set of working drawings for an intersection at grade. The location of the access road to the site has been determined in accordance with the appropriate safe intersection sight distance (SISD) as stipulated by the guidelines. The SISD is defined as the distance required for the driver of a vehicle on the non-terminating approach to observe a vehicle entering from a side street, decelerate and stop prior to a point of conflict. Road Transport (Registration) Regulation 2007 Any vehicle which exceeds the overall dimensions of vehicles as defined in the Road Transport (Registration) Regulation 2007 is considered over-dimension. The Regulation defines the width, height, length and some internal dimensions of vehicles. Vehicles which are overheight, oversize or overmass are subject to special operating conditions. This Regulation contains information for operators of these vehicles, including: Permit notices; B Double, Road Train & 4.6m High vehicle route maps; Route assessment guidelines; Permit Conditions booklet; Road occupancies and development information; and Overheight vehicles - specific information for operators. A vehicle is overheight if, together with its load, it is more than 4.3 metres high. Special conditions apply to overheight vehicles in NSW. Operators must know the height of their vehicle along with its load before they leave the depot. The following AGL compliance guides were considered in the creation of this Plan. LG-HSE-CG Road-Vehicles Safety Compliance Guides 1.7 Licenses and Permits An Environment Protection License will be managed by CBI during construction. Over dimension vehicle permits will be required for such transport. 1.8 Minister s Conditions of Approval and Statement of Commitments The Conditions of Approval relevant to this traffic management plan are listed Table 1-3 below.

12 Traffic Management Sub Plan EN-PL Ensuring that appropriate traffic management measures are implemented and maintained on site. Construction Personnel Following mitigation measures listed in the EWMS when undertaking site work; and Informing the supervisor of any traffic issues as they arise. 2.0 IDENTIFICATION AND ASSESSMENT 2.1 Assessment Traffic, roads and infrastructure impact assessment was prepared by AECOM Australia Pty Ltd (Appendix 12 to the EA). The aim of the assessment was to characterise the existing traffic environment, assess any potential Project-related traffic impacts and propose mitigation and management measures to ameliorate the impacts. The traffic assessment involved inspections of the road networks within the study area, and consultation with the appropriate bodies including the RMS and Port Stephens Council. The impact assessment was based on the total forecast traffic load (i.e., the additional traffic) generated by the Project during construction, in addition to current traffic loads. 2.2 Existing Environment The Tomago area supports light to heavy industrial activity, with some commercial and residential land uses. This area is served by the local road network that includes Old Punt Road and Tomago Road. The Pacific Highway is in the west of Tomago. Approved B-Double Routes All of the major roads in the vicinity of the gas storage facility construction site are RMS-approved for B- double use, including the Pacific Highway, Old Punt Road and Tomago Road. All trucks will enter the site via Pacific Highway, Old Punt Road to TAC Northern Access Road. Public Transport, Pedestrian and Cycle Network Public transport in the vicinity of the site is limited. There are regular bus services along Old Punt Road. There are no off road cycle or pedestrian paths between Hexham and Tomago. 2.3 Site Location and Access The gas storage facility is located in the northeast corner of Lot 105 DP in the Port Stephens Local Government Area (LGA). This site is north of the Tomago Aluminium Smelter on land recently purchased by AGL. The site is approximately 13km northwest of the Newcastle central business district, 8km south of Raymond Terrace and 4km east of the Hexham industrial area. The access road and utility corridor (approximately 1.4km in length) will join the gas storage facility to the TAC northern access road between 130m and 240m south of the intersection of the TAC Northern Access Road and Old Punt Road. The TAC northern access road joins Old Punt Road approximately 200m from the intersection of Old Punt Road and the Pacific Highway. Traffic routing to and from the gas storage facility construction site will be along the Pacific Highway, Old Punt Road and the TAC Northern Access Road. The Project heavy vehicle traffic route is shown in Figure 7-1. The gas pipeline access corridor (approximately 1.7 km in length) is located along the northern boundary of the Primary Project Area. This corridor will also serve as a secondary access road from the gas storage facility site to Old Punt Road for use in emergencies and will be approximately 4 m wide with 1 m shoulders.

13 Traffic Management Sub Plan EN-PL Existing Road Network Pacific Highway The Pacific Highway is a 1,025 km major transport route, which links Sydney and Brisbane along the east coast of Australia. The section of the Pacific Highway in Tomago has two lanes in each direction and a speed limit of 80 km/h. The Hexham Bridge carries the Pacific Highway over the Hunter River and has two southbound lanes and three northbound lanes. The average growth in traffic volume on the Pacific Highway in the Tomago area is 2.5 % per year. The average growth in traffic volume on the Pacific Highway in the area of Hexham is 1.7 % per year. Old Punt Road Old Punt Road is a bi-directional two-lane road, which connects Tomago Road to the Pacific Highway through the Tomago industrial area. The Old Punt Road and Pacific Highway intersection is signalised (i.e., it has traffic lights) with a left turn slip lane from Old Punt Road and a continuous movement in the northbound direction of the Pacific Highway. The southern end of Old Punt Road intersects with Tomago Road at a roundabout. The Old Punt Road and the Pacific Highway intersection has recently been upgraded to improve traffic conditions. The upgrades include: Installing traffic control signals; Providing an improved left-turn lane from Old Punt Road onto the Pacific Highway; and Lengthening the merge lane on the Pacific Highway from Old Punt Road. TAC Northern Access Road All trucks carrying bulk materials to and from the smelter use the TAC northern access road, a private road. The gas storage facility site access road will join the TAC Northern Access Road approximately 140 m south of where the TAC Northern Access Road and Old Punt Road intersects. There are currently an average of 196 truck movements daily bringing raw alumina (i.e., 98 trucks making a trip to and from the smelter) and 36 truck movements bringing petroleum coke to the smelter. There is an average of 186 truck movements associated with dispatching the finished aluminium product per day. This is a total of 418 truck movements (209 truck trips) per day associated with smelter operations. The trucks used for the transport of raw materials are sealed B-double trucks, and are typically semi or B-double flat top trucks for metal products. Future Road Network The proposed extension of the Sydney to Newcastle F3 Freeway is a major road upgrade. A preferred route and a concept design have been prepared. The preferred route commences south of the John Renshaw Drive roundabout, 4.5 km west of Hexham Bridge and travels east. It will cross the New England Highway at Hexham and cross the Hunter River on a new bridge. North of the river, the route will follow the alignment of the existing Pacific Highway in the vicinity of the gas storage facility construction site. The F3 Extension concept design has two traffic lanes in each direction, with a provision to upgrade to three lanes in each direction in the future. The main carriageway will have a design speed of between 100 km/h and 110 km/h. The F3 Extension would divert traffic from the existing Pacific Highway leading to improved conditions on the existing route for local trips and a reduction in crash rates. A new interchange will be constructed between the Pacific Highway and Old Punt Road. The gas storage facility construction site will continue to be accessed from the TAC northern access road off Old Punt Road. Timing of construction and completion of the F3 Extension project is unknown and will depend on funding availability. Uncontrolled if Printed Issue Date: 22 April 2013 Page 13 of 38

14 Traffic Management Sub Plan EN-PL Potential Impacts The primary issues relating to traffic arising from the Project are increased traffic volumes and the change in the traffic composition (i.e., greater proportion of heavy vehicles). Potential impacts associated include a reduction in road safety (particularly at intersections), decreased level of road service (speed, travel time, manoeuvrability and delay), and increased stresses on road infrastructure (such as degradation of road surfaces and the building and upgrading of access roads). Traffic Volume and Composition The construction workforce for the Project is expected to peak at approximately 300 people. The majority of the workforce will come from Newcastle and its surrounds and will travel to the sites by a combination of light vehicles and buses. During Project construction, the volume of both heavy vehicles and light vehicles (Table 2-1) will increase at the Old Punt Road and Pacific Highway intersection and the local road network in the vicinity of the Project. Table 2-1: Construction traffic Component Task Daily Deliveries - Heavy Goods Vehicles Daily Workforce - Light Vehicles Gas storage facility Site preparation 40 to Bulk earthworks Structural works 1 (two month period) 20 to Structural works 2 (remainder of period) Commissioning 3 30 Rehabilitation and landscaping 4 20 Access road and utility corridor Construction The highest number of heavy vehicles during Project construction will occur during Year 1 and the highest number of light vehicles will occur during Year 3 of construction (Table 2-2). Table 2-2: Maximum daily and morning peak hour Project construction generated traffic Year Deliveries (Heavy Goods Vehicles) Workforce (Light Vehicles) Daily Morning Peak Hour Daily Morning Peak Hour A range of equipment will be required during construction including mobile cranes, site vehicles, and diesel generators and welding machines. Working hours for all planned construction activities as required by CoAs are presented in Table 2-3.

15 Traffic Management Sub Plan EN-PL Out of hours work (CoA B29) All works (CoA B30) No out of hours work is required for construction of the gas storage facility component of the project. Implement all reasonable and feasible noise control measures consistent with Interim Construction Noise Guidelines DECCW, July 2009 Risk of a Motor Vehicle Accident There is a potential for an increase in accidents due to the increased traffic movements. Road Network Infrastructure and Access Increased traffic from the Project has the potential to affect the existing road network infrastructure in the vicinity of the Project. The likelihood of any such impacts, such as degradation of road surfaces, is dependent on the existing pavement and infrastructure condition and change in use due to the Project. In terms of indirect impacts, closing of the road shoulder and works within the road verge might at Old Punt Road and TAC Northern Access Road will result in reduced speeds along those roads in the vicinity of the construction works. Section 2.8 describes this work in further detail. Intersections Increased traffic volumes, as well as altered traffic composition have the potential to affect the operation and the safety of the following road intersections: Old Punt Road and the Pacific Highway. TAC Northern Access Road and Old Punt Road. Old Punt Road and Tomago Road. 2.5 Residual Impact Traffic Volume and Composition Old Punt Road and the Pacific Highway Intersection The average annual growth rate on the road network in the vicinity of the site is 2.5%. This growth rate has been applied to the existing traffic flows at the intersection in order to determine peak hour base traffic flows. The predicted peak hour base traffic flows predicted up until the year 2014 indicate that the Old Punt Road and Pacific Highway intersection will perform with minimal average delays. From October 2004 to August 2010, there were 67 crashes on the Pacific Highway between the intersection with Old Punt Road and Hexham Bridge (inclusive). Of the 67 crashes, there were two fatal crashes, 26 injury crashes and 39 non-casualty crashes. One of the fatal crashes occurred at the intersection of Old Punt Road and Pacific Highway. This occurred before the intersection was upgraded to a signalised intersection. Project construction traffic will have a small impact on the intersection in the morning peak hour. The level of service in each future year is likely to drop; however, this is still considered to be performing acceptably according to RMS level of service standards. The intersection continues to operate with spare capacity in the future years (approximately 25% spare capacity). 2.6 Potential for Flooding The gas storage facility plant site has minimal encroachment into the 100-year ARI flood extent and will be raised to 6.35 m AHD, approximately 1.75 m above the 100-year ARI level. Construction of the access road will be designed to match the peak 20-year ARI flood level of 3.1 m AHD. It is unlikely to affect flood characteristics as the cut and fill volumes required are insignificant compared to the flood storage capacity of the area (Figure 7-3). Flood peak level will be 4.6 m AHD likely resulting in some localised areas of inundation along the northern section of the site (typically less than 0.5 m deep) and at the northeast corner of the site (less than 1.0 m Uncontrolled if Printed Issue Date: 22 April 2013 Page 15 of 38

In principal Port Stephens Council had no issue with the implementation of the Plan and made comment in Section 2.2 and Section CBI and their subcontractors will consult with Tomago Aluminium Company and Port Stephens Council with regards to site specific traffic control plans and timing required for road works in connecting services to the gas storage facility. CBI will seek approval from Tomago Aluminium Company for sighting of their temporary site compound as described in Section AGL and the ER may participate in the further development of this Plan should they raise specific concerns during the period of road works and generally with regard to traffic during construction of the Project. Consultation will be undertaken by CBI through AGL s Community Liaison Coordinator and Community Engagement Plan should any complaints arise relating to traffic. 3.2 Training and Awareness As stated in the CEMP all project personnel and subcontractors will receive training in both CBI s and their personal environmental obligations during the inductions and toolbox talks. From time-to-time staff may also attend specific training sessions when deemed necessary by the EM. All project personnel will undergo a general project induction prior to commencing work with CBI. This will include a traffic management component to reinforce the importance of traffic issues and the measures that will be implemented to protect the environment. Ongoing toolbox talks will highlight the specific environmental requirements for activities being undertaken in each work area. These will be based on the measures outlined in the relevant EWMS and relevant CBI sub plans. Examples of topics that will be covered during project induction and toolboxes include: General traffic rules when entering and leaving the construction areas; Site access at compound on TAC Northern Access Road; TAC traffic and give way priority; Traffic controls required for Road works required for installation of services; The employment of reasonable and traffic control mitigation measures; and Roles and responsibilities of the Project team related to traffic management generally.

19 Traffic Management Sub Plan EN-PL IMPLEMENTATION OF CONTROLS 4.1 Traffic Incident Mitigation and Management Measures Project mitigation measures and responsibilities for the design and construction of works associated with traffic management are outlined in Appendix C. These mitigation measures have been developed from the SoC, mitigation measures described in the EA and to ensure compliance with relevant CoA, legislation and best practice. In accordance with SoC 260, temporary impacts to road infrastructure during the construction phase will be rehabilitated and reinstated by AGL. To indemnify Council and RMS, AGL will arrange for a public liability policy to cover the RMS for public liability in relation to the Project works for an amount of $20 million as per SoC MONITORING AND REVIEW 5.1 Monitoring, Inspection and Reporting Visual traffic monitoring will be undertaken by the Environmental and Safety Advisors during the construction phase of the Project to verify compliance with the CoA objectives, and to determine if the actual construction traffic generated meets the predicted levels identified in this Plan. Documented weekly environmental inspections of the construction site will also be undertaken by the EV through the weekly environmental inspection checklist and forwarded to the EM. The weekly checklist includes a section on traffic controls. The Environmental Review Group (ERG) and ER will inspect the site regularly. Any actions to be undertaken as a result of any site inspection will be recorded in the CBI Environmental Action Register. Traffic controls inspection and reporting program is listed in Table 5-1 below.

20 Traffic Management Sub Plan EN-PL Activity Area Resources Responsibility Frequency Reported To Against Targets 5.2 Auditing Performance Report Three monthly internal audits for compliance against the CoA, SoC and other relevant licences and approvals will be undertaken (shown in Table 5-1) and include an audit of the worksite and subcontractors to assess compliance with this Plan and site EWMS, including traffic control monitoring, reporting and incident management. The findings of these audits will be incorporated into the construction compliance tracking program (CTP). The EM will be responsible for managing and implementing actions from these audits. Regular environmental compliance audits against the EWMS (Task Observations as described in Section of the CEMP) will also incorporate any concerns relating to air quality. 5.3 Non-Compliance Management Where traffic incidents are found to increase, the cause / source of excessive incident generation will be identified, the EM will consult with the Construction Manager and CBIs subcontractors, and any additional reasonable and feasible measures available will be implemented to reduce traffic incidents or concerns. If deficiencies are identified and non-compliances with the environmental requirements and the objectives of this Plan (as outlined in Section 1.3) are observed, this will be reported as an environmental incident (in accordance with Environmental Incident Reporting Procedures) and relevant actions / mitigations will be enforced. Details of all non-compliances and corrective actions taken will be included in the six monthly compliance reports. 6.0 INCIDENT MANAGEMENT All environmental incidents occurring on the Project will be managed by CBI as detailed in Section 5.5 of the CEMP. This includes notification, recording, reporting and response processes. Uncontrolled if Printed Issue Date: 22 April 2013 Page 20 of 38
