5 Introducing Perth Airport s New Runway Introduction This summary of the Major Development Plan (MDP) for Perth Airport s proposed new runway introduces an important piece of infrastructure for Western Australia. Because the new runway will take approximately four to five years to construct, Perth Airport is seeking approval for the new runway by This document has been produced to help inform interested parties with the main points of the MDP, which forms a key part of the approval process for the runway. The MDP itself has been published for community consultation, before being considered for approval by the Commonwealth Minister for Infrastructure and Transport. It will be made widely available, including online at Perth Airport s website newrunway.com.au. The MDP comprises four substantial volumes: Executive Summary, Volume A: Background and Need, Volume B: Environment, Heritage and Traffic Assessment, and Volume C: Airspace Management Plan. The approval of the new runway is principally informed by the current Perth Airport Master Plan 2014 and Commonwealth and State legislation. This legislation includes the Airports Act 1996 (Commonwealth), the Environmental Protection and Biodiversity Conservation Act 1999 (Commonwealth) and the Aboriginal Heritage Act 1972 (WA).

7 Community Engagement The MDP has been prepared to meet the legislative approvals required by the Commonwealth s Airports Act 1996 for the new runway project as well as to meet the public engagement requirements for aviation airspace-management changes that are required by the Commonwealth s Environment Protection and Biodiversity Conservation Act The MDP is therefore a combined approvals document to ensure that the entirety of the new runway project is properly represented and assessed. One of the objectives of the Airports Act 1996 is to ensure an appropriate level of vigilance, transparency and scrutiny of airport planning so that public interests and requirements are met, as an airport s development progresses. Successful development of Perth Airport therefore depends on productive interactions with a wide range of stakeholders who are impacted by, and who may impact, the airport s development. Extensive Consultation Perth Airport appreciates it is important for the community to be fully informed about major projects that may affect the community. Therefore Perth Airport is committed to effective and transparent engagement with the community. Public Comment The MDP requires many technical reports and assessments, which results in the document being substantial in size. Perth Airport recognises that the size of the MDP document and the level of technical information may discourage public engagement and consequently awareness of the new runway. Therefore the process for releasing the MDP for public comment includes a range of engagement activities and the production of additional publicly available material, to help understand the new runway project. Additional information on the new runway project can be found online at newrunway.com.au, or by visiting one of the displays at local shopping centres and community expos around Perth. Locations of displays and community events are published at newrunway.com.au. Perth Airport has also opened the Perth Airport Experience Centre for the community to visit. The centre has information on the new runway project, including interactive displays. Queries regarding the MDP and all public submissions should be addressed to: New Runway Project Perth Airport Pty Ltd PO Box 6 Cloverdale, WA newrunway@perthairport.com.au Online submissions: newrunway.com.au Phone: (1800 NEW RWY) Submissions must be received by 5pm (WST) Friday 24 August Perth Airport will consider comments received during the public comment period in the preparation of the Draft MDP for submission to the Commonwealth Minister for Infrastructure and Transport.

9 The Proposed New Runway Outline The new runway will occupy 293 hectares, be 3,000 metres long and will be located parallel to the existing main runway with a 2km separation so that both can be used independently. The 293-hectare project area will include infrastructure such as taxiways, lighting, navigational aids, as well as other ground-based infrastructure, drainage and emergency response facilities. A draft Airspace Management Plan has been developed to cater for the changes to airspace and flight paths. A decision on the future of the existing cross runway will be made once the new runway is operational and there is a possibility that it will close. Opening Year It is planned that the new runway will be operational at its earliest by 2023, based on high traffic growth scenarios, or 2027 based on a central growth scenario. The actual year is dependent upon reaching commercial agreement with airlines and expected demand. Because of this variable opening date, an opening year of 2025 has been used throughout the MDP for planning, analysis and forecasting purposes. Planning and Development The need for a new runway was first recommended in the 1970s by a joint Commonwealth and State Government Committee investigating Perth s planning requirements. The planning and location for the new runway was then confirmed in Perth Airport s first public Master Plan, in Perth Airport will become much busier whether or not the new runway is built. The new runway will allow better management of the air-traffic growth that s already occurring, thereby improving efficiency, customer service and the effectiveness of operations. However, there will come a stage at which the additional runway will allow a greater volume of air traffic than the current runway system can accommodate.

10 About Perth Airport Perth Airport has been an integral part of the community since its construction in the 1940s. A Vital Role Perth s relative isolation and the vast distances between Australian population centres make air travel and therefore Perth Airport indispensable to both the people of Western Australia and the state s economic, social and cultural development. Perth Airport handled 13.8 million passengers and 135,220 aircraft movements in 2016, and expects to grow to more than 35 million passengers and 241,000 aircraft movements by The airport facilitates international access to many global destinations as well as interstate domestic travel; and is a vital asset for regional communities and the resources industry. In 2018, Qantas started direct flights from Perth Airport to London Heathrow on the Boeing Dreamliner. Majority-Owned by Super Funds Perth Airport is operated by Perth Airport Pty Ltd, which is a wholly owned subsidiary of Perth Airport Development Group Pty Ltd (PADG). More than 50 per cent of PADG is owned by superannuation funds, including AustralianSuper and Sunsuper. Being a private organisation, Perth Airport will privately fund the $520 million investment needed for the new runway without the need for government subsidies or funding. Majority-owned by super funds +50% of Perth Airport owned by superannuation funds 10 New Runway Project Preliminary Draft Major Development Plan May 2018

11 Planning for the new runway commenced in the early 1970s. Perth Airport is the only aerodrome that supports large passenger aircraft in the Perth region. The new runway will facilitate safe, effective and efficient air services for Perth and Western Australia well into the future. A Significant Employer In 2013, the number of people employed by Perth Airport (both directly and indirectly) was estimated at 12,570 aviation and 5,230 non-aviation-related full-time employees. Delivering the Future Perth Airport is committed to planning towards delivering for the future needs of our airline customers and the expectation of our passengers. Our next wave of investment will include a significant expansion of the international terminal, the consolidation of the Qantas Group at Airport Central and a new runway with associated infrastructure, totalling an estimated $2.5 billion investment over the next 10 years. $2.5b INVESTMENT The new runway forms part of a privately funded $2.5b investment program over the next decade at Perth Airport. Perth Airport will work with our airline customers to understand their needs and agree on investments required to deliver expansion and infrastructure requirements. New Runway Project Summary 11

12 Need for a New Runway The requirement for additional runway capacity is triggered when annual aircraft movements reach 145,000 movements. This figure was temporarily exceeded in 2013 due in part to the mining construction boom, when annual aircraft movements peaked at more than 151,000. This resulted in significant and costly delays to passengers and airlines. Although movements have since dipped (to 131,000 in 2017), they are expected to steadily grow and are forecasted to reach approximately 172,000 movements by 2025 and 241,000 by Without the additional runway capacity planned to be provided by the new runway, by 2025 unacceptable delays would regularly occur at Perth Airport. Projecting forward to 2045, approximately 140 aircraft movements would be forgone each day or approximately 51,000 aircraft movements per year, resulting in substantial costs and acting as a significant constraint to the State s population, cargo capacity and export growth. 241,000 forecast annual flights by 2045 Aircraft Movements (000 s) (Actual) International Freight 2013 (Actual) 2014 (Actual) Domestic Total General Aviation Annual Runway Capacity 2015 (Actual) 2016 (Actual) New Runway Project Preliminary Draft Major Development Plan May 2018

13 Benefits of the New Runway Economic Benefits Construction of the new runway will add $329.1 million to real income in the Perth Region. After opening, the operational contribution of the new runway will grow from approximately $40 million in 2026 to $385 million in 2045, or a cumulative total over this time of nearly $1.2 billion. This boost to real income is the result of additional operational expenditures by Perth Airport and airlines, cost savings from airlines due to reduced delays, business cost savings from reduced delays to business travelers, and increased tourism expenditure. Tourism Air services are the lifeblood of Western Australia s tourism industry: 93 per cent of visitors travelling to the State use air transport. Tourism expenditure as a result of the additional air-traffic capacity enabled by the new runway is estimated to be $302 million annually, or a cumulative $1.72 billion between 2027 and Passenger growth leads to economic growth 93% of visitors travelling to WA use air transport New Runway Project Summary 13

14 $2.39b increase in real income nationally in first two decades of operation $1.72b lost tourism expenditure over 20 years if the runway is not built $887m how much businesses will save by 2045 from avoided delays Productivity Improvements The additional capacity provided by the new runway will result in productivity improvements to airlines as well as productivity gains to business through fewer delays. In 2012 at the height of the mining boom, a Western Australian Treasury report estimated that the annual impact to the airline industry and its passengers of delays being experienced was $72 million. Qantas estimated that the annual impact of runway delays at Perth Airport cost $10.8 million per year, while the Chamber of Minerals and Energy WA stated that a one hour delay at a mine site cost approximately $100,000. Modelling undertaken by Perth Airport shows the avoided delay costs to airlines (comprising maintenance, crew and fuel costs) equate to $ per minute of delay. By 2045, the cumulative savings to airlines as a result of the new runway is estimated at $84 million for Perth, $1.3 million for the rest of WA, and $993 million for the rest of Australia (where most domestic airlines are headquartered). $72m/yr cost to airline industry and passengers 17,800 number of people employed directly and indirectly at Perth Airport in 2013 The cost of delay at Perth Airport is calculated at $48.52 an hour for leisure travellers and $ for business travellers. By 2045, the avoided delays as a result of the new runway are forecast to achieve a cumulative business cost saving of $887.3 million. 14 New Runway Project Preliminary Draft Major Development Plan May 2018

15 Alternatives Considered Instead of building a new runway, several other options were examined. These included achieving more capacity from existing runways at Perth Airport through improved operations, increasing the use of other airports in Perth and around the State, and extending the existing runways at Perth Airport. The MDP explains in detail why, after careful and thorough consideration, none of these alternatives were considered suitable. Safety Safety is the most important consideration for air navigation and aircraft operations. While a number of potential hazards and risks have been identified for aircraft operations on the new runway, the majority are common to aircraft operations around the world. They are therefore mitigated to the highest level possible through regulatory requirements and standards, and airport and aircraft operator processes and procedures. While the likelihood of an aircraft crash incident will potentially rise with an increase in aircraft operations, the overall risk of an aircraft crash incident posed by the development of the new runway is as low as reasonably practicable.

Perth Airport recognises that landuse and infrastructure decisions made both inside and outside the Gorrie The Lakes airport boundary affect its capacity to meet community needs. State Government The new runway project is consistent with State planning policy including: Directions 2031 and Beyond This is a high-level spatial framework and strategic plan for the Perth and Peel regions. It identifies Perth Airport as a specialised centre and recognises it as critical to supporting the growth in the West Australian resource sector as well as providing Western Australia s primary link to the rest of Australia and the world. Draft Perth and 3.5 Million This strategy includes the next layer of detail to underpin State planning policy and Directions Perth Airport is referenced as a specialised activity centre as a key employment node. Local Government y Paulls Valley Hacketts Gully ing lls Reservoir Pickering Brook Sawyers Valley WA State Aviation Strategy Published in 2015, this strategy confirms the status of Perth Airport as the sole and principal 24-hour airport for the Perth metropolitan region. Malmalling A key finding of the Strategy is that the new runway will: provide the step-change in capacity needed to cope with current peak-hour demand as well as accommodate continuing high levels of growth at Perth Airport, and will benefit all users, improving reliability, reducing delays and permitting peak-period demand growth across interstate and international sectors, as well as resource and other intrastate users. Flynn The Perth Airport estate sits within three local authority areas, divided between the City of Belmont, City of Swan and the City of Kalamunda. However, Perth Airport operations impact local government planning within a much wider catchment of the Perth metropolitan area largely due to the central location; only 12 kilometres from the Perth CBD and within the metropolitan arterial road network. There are 17 local government areas within a 15-kilometre radius of the airport. The new runway project was found to be consistent with the relevant local planning schemes. State Planning Strategy 2050 This identifies the need to provide efficient transport routes and hubs. Karragullen Airport Boundary KILOMETRE Lesley It recognises Perth Airport as a key element in the movement network of the State, and as the international gateway to Perth and Western Australia, and the focal point for the growth of the tourism industry.

18 Impact Assessment Like many other major infrastructure project bringing significant longterm benefits to Perth and Western Australia, the new runway will affect the environment and local community. However, the new runway provides the capacity to handle the inevitable increasing numbers of passengers and aircraft in a planned and strategic manner. Perth Airport has undertaken extensive technical analysis to design, assess and mitigate the impacts of the new runway. These assessments are thoroughly detailed in the MDP, in which the significance of the identified impacts have been determined by the application of a risk-based impact assessment framework. This framework considers consequences to the environment and how these impacts can be mitigated. If the risk rating was found to be medium, high or very high, additional mitigation measures were applied. The main impacts and mitigation measures are summarised below. The following impacts have been considered: Aboriginal and European heritage Air quality and greenhouse gas Aircraft noise Flora and vegetation Geology and soils Ground-based noise Health Water (hydrology) Landscape and visual Traffic disruption: runway construction Traffic disruption: runway operation Wildlife Impact Significance Criteria Significance criteria are used in the MDP to provide a quantitative description of each impact, and to help identify the scale of its impact on the environment These descriptions indicate both the duration and the magnitude of each impact. The following tables provide examples of significance criteria (e.g. moderate adverse ), the likelihood of an action having an impact (e.g. possible) and definitions of relative durations (e.g. medium term ). Magnitude description Major Adverse High Adverse Moderate Adverse Minor Adverse Negligible Beneficial Example Criteria Impacts considered critical to the decision-making process. They tend to be permanent, or irreversible, or otherwise long term, and/or can occur over large scale areas. Environmental receptors are extremely sensitive, and/or the impacts are of national significance. Typically, mitigation measures are unlikely to remove such effects. Impacts likely to be of importance in the decision-making process. They tend to be permanent, or otherwise long to medium term, and/or can occur over large or medium scale areas. Environmental receptors are high to moderately sensitive, and/or the impacts are of State significance. Impacts relevant to decision making, particularly for determination of environmental management requirements. These impacts tend to range from long to short term, and/ or occur over medium scale areas or are focused within a localised area. Environmental receptors are moderately sensitive, and/or the impacts are of regional or local significance. Impacts recognisable, but acceptable within the decision-making process. They are still important in the determination of environmental management requirements. These impacts tend to be short term, or temporary and at the local scale. Minimal change to the existing situation. This could include for example impacts which are beneath levels of detection, impacts that are within the normal bounds of variation or impacts that are within the margin of forecasting error. The new runway results in an improvement in the baseline situation, for example, improved downstream water quality. Significance criteria Source: Perth Airport 18 New Runway Project Preliminary Draft Major Development Plan May 2018

19 Mitigation Perth Airport will use mitigation measures to reduce the risk associated with an activity. These mitigation measures are implemented in the following preferred order: 1. Avoid the need for mitigation: eliminate the need for mitigation by the appropriate location of infrastructure associated with the new runway. For example, making the decision to reduce the length of the runway from 3,800 metres to 3,000 metres and shifting it further to the south, to preserve the heritage values associated with Munday Swamp. 2. Design-out the risk: minimise significant impacts by including appropriate sustainability measures such as creating natural living streams in our drainage network. 3. Implement an environmental management plan: these measure and minimise any impacts to the greatest possible extent. For example, acid sulfate soil-management measures during ground-disturbance activities. 4. Compensate for impacts where they can t be adequately mitigated and residual effects predominate. For example, acquiring environmental offsets consistent with Commonwealth Environmental Offsets Policy (2012), for the loss of the Banksia Woodlands of the Swan Coastal Plain threatened ecological community and black cockatoo species habitat. There are two types of mitigation: 1. Standard mitigation: this takes account of standard practice and statutory obligations. For example, implementing erosion and sediment control could reasonably be expected to be in place for the construction phase. 2. Additional mitigation: this reduces the significance, likelihood or risk of an impact occurring and is relevant to impacts which are identified as medium, high or very high risk. For example, using cut-off trenches in the design to minimise migration of contaminants in groundwater. Relative Duration of Environmental Impacts Temporary Short Term Medium Term Long Term Permanent / Irreversible Duration of environmental impacts Source: Perth Airport Likelihood of impacts Highly Unlikely Unlikely Possible Likely Almost Certain days to months up to one year from one to five years from five to 50 years more than 50 years Risk probability categories May occur only in exceptional circumstances - can be assumed not to occur during period of the project (Probability less than ten per cent) Event is unlikely to occur, but it is possible during period of the project (Probability ten to 30 per cent) Event could occur during period of the project (Probability 30 to 70 per cent) Event likely to occur once or more during period of the project (Probability 70 to 90 per cent) Very likely to occur as a result of the proposed project construction and/or operations; could occur multiple times during relevant impacting period (Probability greater than 90 per cent) Likelihood of impacts Source: Perth Airport New Runway Project Summary 19

21 Aboriginal and European Heritage Impacts two Aboriginal sites will be impacted by the construction and operation of the new runway and its infrastructure no places of European heritage significance will be impacted Explanation The land on which Perth Airport is located forms part of the traditional network of communication routes, meeting places and camping sites of the Nyungah Whadjuk people. The Aboriginal heritage values within the area of the new runway comprise archaeological and ethnographic sites that indicate prior occupation. As the traditional custodians, the Nyungah Whadjuk people maintain a strong interest in the airport land and its operations. Following consultation with the traditional custodians and relevant organisations, Perth Airport submitted an application under section 18 of the Aboriginal Heritage Act 1972 (WA) to seek approval to develop, maintain and operate the new runway. The application was subsequently approved by the State Government in May The new runway area comprises two known Aboriginal heritage sites that meet the definition of a site under the Aboriginal Heritage Act These sites are listed as archaeological scatters on the Department of Planning, Lands and Heritage s Register of Aboriginal Sites. European heritage is linked to the establishment of the Swan River Colony in Two sites within the vicinity of the new runway project area have been classified as indicative places on the Commonwealth Heritage List in relation to natural heritage values. Mitigation Perth Airport acknowledges the cultural value of Munday Swamp and, where practical, has minimised impacts while ensuring that the new runway can be developed and operated safely and effectively. Perth Airport remains committed to ongoing engagement with the traditional custodians under the guidance of Perth Airport s Heritage Management Framework. The commitments extend to undertaking engagement in a manner that recognises the significance of the area to the Nyungah community, and to acknowledge the strong link that exists between the traditional custodians and the land on which Perth Airport is situated. In recognition of the heritage values within the estate, Perth Airport has made significant modifications to the design of taxiways, boundary fences, roads, drainage and approach lighting to minimise impacts to Munday Swamp. A range of measures will be applied throughout the construction of the new runway to mitigate impacts to heritage values. Munday Swamp Munday Swamp is an ethnographic site and wetland that covers approximately 20 hectares of land in the north-eastern area of the airport estate; a portion of the new runway project area intersects with the southern portion of the wetland. It is believed Munday Swamp was named after a young Nyungah man called Munday, the leader of the Beeloo people in The site was originally recorded by archaeologists in 1979 and has been the subject of many archaeological and ethnographic surveys. Munday Swamp is a ceremonial and mythological site that is of importance to persons of Aboriginal descent. The original airport master plans planned for the new runway to be 3,800-metres long. However, the Master Plan 1999 reduced the length of the new runway and moved it south. This was done as the original plan for the new runway would have required the complete removal of Munday Swamp. The change to the runway length meant Munday Swamp would be materially retained and impacts minimised as much as practical. Subsequently, in contemporary concept development, Perth Airport has made significant adjustments to taxiways, boundary fences, roads and drainage to further minimise impacts on Munday Swamp. New Runway Project Summary 21

22 Wildlife Impacts loss of fauna habitats loss of biodiversity Explanation The construction and operation of the new runway will affect wildlife through the loss of some of their habitat and foraging areas. The main wildlife impacted will be the nationally listed Forest Red-Tailed Black Cockatoo and Carnaby s Black Cockatoo. Although these birds forage on the airport estate, there is no evidence to show they breed on the estate. There are also impacts to the habitats of twelve species either listed under the Wildlife Conservation Act 1950 or as a priority species by the Department of Biodiversity, Conservation and Attractions, including the Quenda (Southern Brown Bandicoot) and Rakali (water-rat). Mitigation Clearing will be designed to retain habitat corridors where possible. Where species are directly impacted, translocation will occur. Appropriate management plans and mitigation efforts will be applied to minimise impacts to fauna located in remaining habitats adjacent to the new runway area, including the control of feral animal species, weed and dieback management, and management of the local hydrology. Perth Airport will acquire suitable offsite environmental offsets. These will be transferred, at no cost, to the State Government for protection in perpetuity. Health Impacts there is limited research and definitive evidence around the correlation and impact of aviation noise and human health health impacts may include sleep disturbance and associated effects, cardio-vascular disease, cognitive outcomes and annoyance Explanation Since 1993, around the world there has been over 170 research papers that have explored the relationship between aircraft noise exposure and/or aircraft emissions and health impact to surrounding communities. No specific research has been completed in Perth. In general, the research has shown that: the most adverse health effect from noise sources, such as aircraft, (and road and rail) noise, is considered to be sleep disturbance. This is due to the knock-on effects of sleep deprivation that include an increased long-term risk of obesity, diabetes and cardiovascular outcomes, that noise disturbance may impact some cognitive outcomes and some areas of learning in primary-age school children, noise exposure may be linked to an increased risk of hypertension and the linked increased risk of ischaemic heart disease, 22 New Runway Project Preliminary Draft Major Development Plan May 2018

23 perceived and real health consequences of aircraft noise exposure contribute to the annoyance that the noise provokes, and annoyance can result in increased stress which can lead to health consequences. Annoyance is a subjective impact which varies between individuals, and the health consequences associated with air pollution include stroke, heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma, with particulate matter being the major cause. The operation of the new runway, and flight path changes to accommodate the parallel runway system, will see aircraft overfly newly affected residential areas at night time, and a number of kindergartens, pre-schools and schools that may be sensitive to cognitive and learning impacts. The extent of health effects caused by the noise levels predicted to occur from the new runway are likely to be smaller than demonstrated in much of the research. This is due to Perth Airport s lower levels of aircraft activity. Annoyance can be reduced through information, engagement to improve understanding of aircraft noise, and, for those affected, manage the noise in the least intrusive way reasonably possible. Operation of the new runway will eventually result in a greater number of annual aircraft movements than could otherwise operate at Perth Airport. Noting the height of operations, and dispersal of emissions, this increased aircraft capacity will result in only small increases in pollution levels. However, the increased efficiency in operations due to the parallel runway system will also have some impact in reducing emissions by reducing airborne delays for incoming aircraft, and ground running for aircraft queued for departure. This, in turn, will reduce engine run times (and emissions) from arriving aircraft, and aircraft with engines running and awaiting departure. Mitigation With careful planning, and through engagement with affected populations, the health impacts resulting from the new runway s operations are likely to be small or restricted to relatively few people. Strategies to minimise noise impact can assist in reducing the potential health consequences of aircraft noise exposure. These include appropriate land use planning around airports, careful route planning, noise-abatement procedures, and providing clear and comprehensive information about the likely exposure of the aircraft noise. In addition, information can be provided to help those affected by the exposure to aircraft noise to undertake amelioration measures that can reduce noise penetration into homes. Perth Airport will continue to encourage industry and Government to undertake further research to understand and manage the relationship between exposure to aircraft noise and community health impacts.

24 Water Impacts changed stormwater flows through the estate increased stormwater runoff possible contamination of surfacewater drainage channels Explanation The new runway will affect the water infrastructure of Perth Airport. This will include redirecting two major engineered stormwater channels (the Southern Main Drain and the Northern Main Drain) that run through the airport estate. Vegetation and Flora Impacts clearing of two Commonwealth-listed threatened flora species, Conospermum undulatum and Macarthuria keigheryi clearing of hectares of Banksia Woodlands of the Swan Coastal Plain threatened ecological community potential spread of weeds and dieback: 40 per cent of the vegetation within the new runway area is infested with Phytophthora cinnamomi (dieback disease) Explanation The new runway will require the clearing of approximately 129 hectares of vegetation in good or better quality. Over half of the new runway area comprises completely degraded areas, degraded areas, or areas completely devoid of vegetation that has been replaced by infrastructure. The completely degraded areas and degraded areas harbour large populations of introduced species including declared pests and weeds of national significance. These areas are not of conservation significance. No vegetation in the new runway area was considered to be in pristine condition. This is due to the presence of weed species, evidence of disturbance from feral animals, and the presence of vehicle tracks resulting from the long term historical uses on the land. Mitigation Perth Airport is committed to an environmental offset strategy to address the loss of Commonwealth listed species. This will be undertaken pursuant to the Commonwealth Environmental Offsets Policy (2012), in consultation with the Commonwealth Department of the Environment and Energy, and the State Department of Biodiversity, Conservation and Attractions. The drainage realignment for the new runway will restore the original water flow of Munday Swamp connecting upstream to Poison Gully and downstream to Limestone Creek (which connects to the Swan River). This means water flows can return to a more natural form. Modelling indicates that the proposed changes won t cause any flooding, either on or off the estate. Mitigation The new stormwater infrastructure will be designed so that the water flowing off the estate, and ultimately into the Swan River, will be of equal or better quality than the water flowing onto the estate. Additional water will flow into Munday Swamp but this will be managed by design of the infiltration basin and controlling the water flow s velocity. Living streams are planned for both the Southern and the Northern Main Drains. This will result in their open channels mimicking the characteristics of natural streams with trees, bushes and shrubs, and in-stream vegetation which will allow for groundwater infiltration and carriage of peak flood flows in a natural manner. Construction activities that result in a risk of mobilising sediment, acid sulfate soil and other contaminants into Munday Swamp, will be managed through the design process and via the implementation of a construction environmental management plan. Weed and pest-management measures and vehicle-movement control will be applied to mitigate the risk of dieback infection to other areas within the estate and into surrounding communities. 24 New Runway Project Preliminary Draft Major Development Plan May 2018

25 Air Quality and Greenhouse Gas Impacts low impact on air quality and greenhouse-gas emissions reduced aircraft emissions expected in the future Explanation Sensitive receivers considered in the air-quality assessment include schools, hospitals, aged care homes, childcare facilities, offices, public recreation areas, protected wetlands and residential properties. The potential impact of the new runway s aircraft operations on air-quality impacts and greenhouse gas emissions is determined to be low. The predicted concentrations of all criteria pollutants and air toxics comply with the assessment criteria. Emissions from newer aircraft are anticipated to reduce in the future as engine technologies improve, and it is likely that the impact of new runway operations on airquality concentrations will reduce in years to come. The increased volatile organic compounds (VOC) emissions associated with aircraft operating on the new runway are considered unlikely to result in significant nuisance odour impacts. Taxiing typically accounts for more than 60 per cent of VOC emissions from aircraft in the landing take-off cycle. Unnecessary taxiing, which will be minimised by the new runway, reduces the airport s efficiency and increases the amount of fuel used. Mitigation Perth Airport places considerable emphasis on the layout of the taxiway network to reduce the amount of taxiing required. Geology and Soils Impacts contamination of soil and underlying groundwater disturbance of acid sulfate soils and asbestoscontaining materials soil erosion and sedimentation ground movement and changes in levels Explanation In order to build the new runway, the ground will have to be levelled out. This will involve disturbing the soil, which may result in: acidity: the release of acidity by disturbing acid-sulfate soils, and some soil erosion: the erosion potential of the shallow soils within the new runway area have been identified as very high. Concentrations of per-and polyfluorinated alkyl substances (PFAS) within the new runway area were below the laboratory limit of reporting. PFAS are aqueous film-forming foams containing per- and poly fluoroalkyl substances, and Perfluorooctane sulfonate (PFOS) belong to this group of substances. PFAS is used in a variety of household and commercial activities., such as water resistance treatments of upholstery and carpets, paper food wraps, and shampoos. Only three per cent of 3M globally manufactured PFOS was used in making firefighting foam. Mitigation All works will be done consistent with a Construction Environmental Management Plan which will be prepared prior to works commencing. PFAS will be managed consistent with the recently released Commonwealth PFAS National Environmental Management Plan To manage the impacts of ground movement during construction, further geotechnical studies to inform consolidation and settlement will occur beforehand. Detailed analysis and design of excavation and soilretaining systems will also take place, along with careful construction sequencing during excavation. Settlement will be monitored and early intervention undertaken if needed. Erosion control and management will be necessary throughout construction and during operations, in accordance with industry practices. The spill of hazardous substances and hydrocarbons during the construction phase has been classified as a medium risk. It is intended that low-impact and low-toxicity chemicals are used where practicable to reduce the risk. Construction and operation of the new runway will include a range of management measures, including preparation and implementation of an Acid Sulfate Soils and Dewatering Management Plan. Active acid-sulfate soils management (stockpiling) and treatment (addition of lime) will be required to protect local soil and groundwater from the release of acidity and metals. Remediation of the existing contaminates will result in a beneficial impact whereby contaminants are removed; appropriate risk minimisation will be undertaken where contaminants are left in situ. New Runway Project Summary 25

26 Traffic Disruption: During Construction Impacts temporary disruption due to construction traffic within the airport and adjacent road networks Explanation The construction traffic is temporary and will not adversely impact on the internal or external road networks. The importation of fill for bulk earthworks will be the highest impact activity of new runway construction to the surrounding road network. A conservative program of 16 months for bulk earthworks results in an average of 12 vehicles per hour delivering materials to the site. Construction vehicle access can be provided at six locations off Horrie Miller Drive and Abernethy Road, reducing the impact on the traffic network. There will be an estimated 100 staff vehicles and 100 general deliveries a day at peak construction stage. Mitigation A traffic management plan will be prepared and agreed prior to construction works commencing. In addition, debris-removal facilities (such as a washdown facility or rumble strips) for vehicles leaving the site will be considered to ensure the public road network is kept free from construction materials. Traffic Disruption: During Operations Impacts minimal increase in road traffic re-closure of Grogan Road Explanation The growth in road traffic resulting from the new runway will be minimal when compared to the increase in traffic volume that would occur whether or not the new runway is built. There will however be increased traffic associated with peak-period flights (because more flights can be accommodated by the new runway) and with the increase in flights to meet demand. By 2045, this will cause a moderate adverse impact on the primarily non-airport traffic volumes on Abernethy Road, and only in the morning peak period. The new runway will require the re-closure of Grogan Road. Up to 64 per cent of the traffic using Grogan Road during peak periods is non-airport traffic which uses the road as a shortcut. Initial planning considered relacing Grogan Road with a tunnel under the new runway. During design work the cost of the tunnel was estimated at around $240 million and therefore it was not financially viable to construct the tunnel for the relatively low number of vehicles that use Grogan Road to access the terminals. All trucks carrying loose material will have their loads covered to ensure dust and debris is contained within the truck. 26 New Runway Project Preliminary Draft Major Development Plan May 2018

27 Landscape and Visual Impacts clearing of vegetation construction and operation of the new runway increased light pollution from runway lighting Explanation The new runway will alter the visual amenity through airside roads and fencing, the runway and taxiway pavements, and the installation of high intensity approach lighting at the northern and southern extents of the runway. The operation of the new runway will see an incremental increase in the existing overall lighting impact to the airport area and its surrounds. Mitigation The design of the runway will consider the visual impact of airfield and approach lighting and ensure compliance with safety regulations. New Runway Project Summary 27

28 Aircraft Flight Paths and Noise Distribution As well as being a major piece of infrastructure at ground level, the proposed new runway will affect how aircraft use the airspace above and around it. Perth Airport is aware of the importance of aircraft noise exposure to the local community and is actively engaged in ways to minimise its impact. The opening of the new runway requires new flight paths for aircraft using the new runway, as well as changed flight paths on the existing main runway to accommodate parallel runway operations. This will alter the distribution of aircraft noise around the greater Perth area some areas will have new or more noise and some areas less. When designing air routes, safety is the key consideration. One of the principles applied is to try and minimise the impact of noise to residential areas. This could be achieved by using flight corridors over industrial areas rather than residential areas where this is possible. It is important to note that the actual flight paths have not yet been designed. This process follows the approval of the MDP and will commence around three years before the first flight. The final flight path design will be undertaken by Airservices Australia, Australia s air navigation service provider. Through a draft Airspace Management Plan, the MDP presents the likely flight corridors. The final flight path design must be consistent with the approved MDP. Volume C of the MDP thoroughly details the draft Airspace Management Plan and its impact assessment. Airspace Management There are procedures to follow when an aircraft departs or arrives at an airport. These procedures would be like directions from your house detailing the route you should drive to reach the highway. As there are a number of runways an aircraft can depart from or arrive to, there are a number of procedures for both departure and arrival because they provide guidance from the runway to the point where the air route (highway) commences or ceases. The way in which aircraft use the skies is called airspace management. Airspace management covers an airports air route structure including the direction from which aircraft land and depart the runway. Both ends of a runway can be used for landing and take-off, and there will be various options that are dependent on the runway end that is used. Because safety is paramount, departure and arrival procedures are designed in accordance with international guidelines. Flight Corridors Flight corridors are corridors in the sky which define the threedimensional routes that aircraft are likely to use to arrive at, or depart from, Perth Airport when the new runway is opened. They are designed to provide a route that ensures aircraft safety and the efficient use of airspace, while ensuring equitable access for all airspace users where practicable. The main criteria when designing flight corridors is the safe separation of aircraft safety always takes precedence in airspace management. However, the impact of aircraft noise exposure on the community is a factor that is taken into consideration as much as possible during the design process. Although they are often shown as a single line on a map, in practice, flight paths can vary by up to several kilometres or more. The reason for this can be due to weather conditions, the requirement to keep a safe distance between aircraft in the sky, or aircraft performance. Ideally, airlines would like aircraft to fly by the most direct route and at the optimum altitude for reasons of economy and efficiency. However, this is not always possible as the route design must provide separation between numerous flight paths. Around airports where the aircraft are at low level, there may also be rules to minimise the aircraft noise impact to surrounding residential areas (referred to as noise abatement) that dictate procedures that are agreed to reduce the impact of aircraft noise to the community. As previously mentioned, the actual flight paths have not yet been designed, rather the MDP presents likely flight corridors. The final flight path design will be undertaken by Airservices Australia around three years before the first flight. 28 New Runway Project Preliminary Draft Major Development Plan May 2018

29 Runway Operations The new runway will be located parallel to the existing main runway. Both ends of a runway can be used for landing and take-off. The use of a certain runway (or combination of runways) is known as the operating flow. Operating flows at Perth Airport are either northerly or southerly. The key considerations when selecting the flow are safety, wind and capacity. The parallel runways will operate independently. This means each runway would cater for arrivals and departures and operate separately from each other. Each flow has a capacity limit, which is heavily dependent on the number of aircraft arrivals and departures each hour. Low cloud, rain and poor visibility can reduce this capacity. North Flow 03L 21R Existing Runway 03R South Flow 03L 21R Existing Runway 03R 21L New Runway 21L New Runway Noise-Abatement Procedures Managing the noise impact on the surrounding community plays a significant role during the runway selection process. The noise-abatement practices and procedures implemented by Airservices can provide noise relief from arriving and departing aircraft. However, the safety of aircraft still remains the number one priority. Possible options Effective mitigation of aircraft noise often requires a number of small, incremental improvements that cumulatively result in a noticeable reduction in aircraft noise. There are three basic options: 1. reduce noise emissions from aircraft, 2. plan infrastructure, flight paths and airport operating strategies to achieve lower impact over noisesensitive areas, and 3. develop land-use planning to ensure that future noise-sensitive uses and developments are not located in noise-affected areas. Noise mitigation for the proposed new runway Aircraft noise-mitigation has been considered during the various stages of the new runway planning and the MDP assessment process. To reduce the impacts of aircraft noise on new communities, a key design principle has been to use existing arrival and departure routes where possible. Airspace design at a large airport such as Perth is complex, and safety is paramount. Constraints increase with the introduction of a new runway, as additional procedures must be developed and existing ones modified to use the new and existing runways. It can be difficult to mitigate aircraft noise emissions through airspace design, because procedures are often dictated by international standards to ensure the safe operation of the airspace. Nonetheless, as much as possible, aircraft noise has been considered in the airspace and proposed flight corridor which has been developed and assessed for the MDP. It is expected that the preferred noise abatement options will be implemented whenever operationally feasible. However, there will be occasions when weather and operational demands dictate that other options are used. Noise abatement procedures are regularly reviewed and updated by Airservices. Other Airports and Users Perth Airport is located 20 kilometres inland from the coast. RAAF Base Pearce is 30 kilometres north of Perth Airport, and Jandakot Airport is 19 kilometres to the south. Perth Airport s proximity to these airports and their operating requirements have resulted in a complex airspace arrangement in the Perth Basin. This affects the use and potential flight-path design for the new runway. To facilitate this mix of airports and users, airspace around Perth is a combination of controlled and uncontrolled airspace (controlled airspace protects passengercarrying aircraft by giving pilots an air traffic control service; in uncontrolled airspace, the pilot is responsible for separation with other aircraft). New Runway Project Summary 29

30 Draft Airspace Management Plan A draft Airspace Management Plan has been developed for the safe and efficient operation of the parallel runway system facilitated by the new runway. It outlines the proposed airspace architecture and flight corridors for Perth Airport once the new runway is operational. The draft Airspace Management Plan is not a detailed design, but rather provides a high level overview of how the runways may operate. The air routes shown are provided as indicative routes and flight corridors, and the final flight path design may differ to cater for safety, operational need and aircraft noise considerations. However the final design must be consistent with the approved MDP. Proposed airspace changes To facilitate the requirements for parallel runway operations, it may be necessary to change controlled airspace to the north and south of Perth Airport. This is to maximise capacity at Perth Airport in all weather and operating conditions. Final design Airservices is responsible for the final design and publication of air routes and arrival and departure procedures at Perth Airport. The final airspace design generally commences three years prior to the first flight on the new runway. It will require engagement by Airservices supported by Perth Airport. Prior to the final design, an agreed operational plan will be developed by Airservices in consultation with the Department of Defence. Future developments, particularly to aircraft technology and navigation systems, may also require changes to the proposed airspace operations. Increases in traffic levels may also affect aircraft operations and procedures, and could result in changes to the procedures used when the new runway becomes operational; the MDP contains all the various approach procedures that could be used. The airspace change has been developed to minimise the impact as far as practicable on other airspace users, while ensuring flexible operational requirements at Perth Airport. Any changes to controlled airspace are subject to review and approval from the national aviation regulator, the Civil Aviation Safety Authority (CASA). 30 New Runway Project Preliminary Draft Major Development Plan May 2018

31 Aircraft Noise Assessment Impacts total aircraft noise over Perth will not increase over the short term the distribution of aircraft noise will change some areas will have a reduced exposure to aircraft noise, some will have an increased exposure to aircraft noise, and some will be affected by noise events for the first time Explanation The opening of the new runway requires new flight paths for aircraft using the new runway, as well as changed flight paths on the existing main runway to accommodate parallel runway operations. This will result in a reduction in the number of noise events for some areas and an increase in noise events for others. Some areas will also be exposed to noise events for the first time. Areas to the east and south/south-east of the airport are the most likely to experience an increase in aircraft noise events or be newly exposed to aircraft noise events. Areas to the west and south-west are the most likely to experience a decrease in aircraft noise events when the new runway first opens. Aircraft noise exposure is described using number above (or N-above) noise contours. The N-above contours illustrate the average number of daily noise events that exceed a certain sound level. The N65 24-hour period contour map shows the average number of events per day over 65 decibels for a particular area. A noise level of 65 decibels outside a building will generally result in an indoor noise level of approximately 55 decibels. This is the approximate sound level at which a normal conversation can generally be disturbed. 24-hour period At day of opening, it is expected that the number of existing dwellings predicted to experience five or more events above 65 decibels over an average daily 24-hour period will decrease from approximately 83,600 to 78,000. Of these, approximately 27,500 dwellings will average at least five fewer daily noise events, 25,600 dwellings are expected to experience an increase of five or more daily noise events, and 24,800 dwellings will not experience a change in average daily noise events. It is predicted that nearly 8,200 dwellings will be newly affected by aircraft noise. By 2045, due to natural growth in aircraft movements and the additional capacity provided by the new runway, the number of dwellings exposed to 65-decibel noise events will return to 82,600. New Runway Project Summary 31

32 Daytime When considering daytime noise (6 am to 7 pm) only, the opening of the new runway is expected to result in a reduction from approximately 69,300 to 68,000 dwellings that could experience five or more 65-decibel noise events. By 2045, due to growth in aircraft movements across both runways, the number of dwellings exposed to 65-decibel daytime noise events will increase to 71,400. Evening During the evening period (7 pm to 11 pm), with the opening of the new runway there is an overall reduction from 20,200 to 16,900 dwellings that may experience five or more 65-decibel noise events. By 2045, due to the growth in aircraft movements across both runways, the number of dwellings exposed to 65-decibel evening noise events may increase to 24,300. Night-time There may be a reduction from nearly 61,200 to 54,900 dwellings exposed to five or more 60 decibel noise events during the night-time period (11pm to 6am) when the new runway opens. By 2045, this will increase to 86,400 exposed dwellings. This growth is experienced across both runways. Mitigation Effective mitigation of aircraft noise often requires a number of small incremental improvements to result in a noticeable reduction in aircraft noise. Perth Airport actively manages aircraft noise exposure and its effect on the community. Strategies to minimise aircraft noise exposure include: plan infrastructure, flight paths and airport operating procedures to achieve lower impact over noisesensitive areas, appropriate land planning around airports through State and Local government policy and decision making, dating back to the early 1980s, to ensure that future noise-sensitive uses are not located in noise impacted areas, engagement with communities, and provision of clear and comprehensible information about the likely aircraft noise exposure and the amelioration measures that can reduce noise penetration into homes. It s important to provide information to residents existing and potential in areas likely to be affected by noise. For current residents, they can better understand the timing, frequency and loudness of noise events. For future residents, they can evaluate whether or not to move into the area. To help with this, Perth Airport has developed an interactive aircraft noise information portal, perthairport.com.au/aircraftnoise. 32 New Runway Project Preliminary Draft Major Development Plan May 2018

33 Ground-Based Noise Impacts noise from ground-based sources during construction and operation of the new runway will be mostly within the airport estate noise impact to surrounding communities is naturally mitigated by distance Explanation Ground-based activities that create noise include construction works, aircraft taxiing, engine ground running, the use of auxiliary power units by parked aircraft, and vehicle traffic in the area within, and surrounding the Perth Airport estate. The noise from ground-based sources is naturally mitigated by the distance between operations on the airport and the nearest sensitive receivers (premises used for purposes that are sensitive to noise, such as aged care homes). Engine ground running is an essential safety check where an aircraft, following maintenance, tests the engine prior to the next flight. At Perth Airport, ground runs are undertaken under strict guidelines which stipulate location, time of day and duration. To the east, the most sensitive receivers will experience an increase in noise, though it will be well below the 75 db criterion set out in the Airports (Environment Protection) Regulations and consistent with the background noise level experienced in an average suburb. Aircraft taxiing noise will impact on the areas adjoining the eastern boundary of the estate. However, the noise levels would be relatively low in comparison to other noise associated with operation of the airport, such as aircraft arrivals and departures. Changed vehicle traffic volumes as a result of the new runway will result in a noise level increase of less than one decibel during peak hour, well below what is detectable by the human ear. Mitigation Good airfield planning that limits taxiing distances is the best way to minimise aircraft taxiing noise. The Engine Ground Run Management Plan already results in very few complaints that can be linked to the running of aircraft engines while they are on the ground. In areas west of the airport, the comparison of noise levels with and without the new runway are within a few decibels for the worst-affected sensitive receivers. This change is marginally large enough for a sensitive human ear to detect the difference. New Runway Project Summary 33
