P E R T H A I R P O R T M a s t e r P l a n 2 0 0 9 10.5 Environmental Considerations Wetlands There are several wetland areas within the Perth Airport Estate. Munday Swamp is considered to be an environmentally significant area. It is also an identified site of Indigenous significance. This swamp forms an integral part of the hydrological regime at the airport and secondly plays a part in the current drainage system, particularly for drainage from catchments upstream of the airport. The airport drainage design will endeavour to minimise adverse impacts due to changes to the hydrological regime or to potential contamination from drainage inflows. Pollution Control Pollution control is an integral part of any drainage system. All developments at Perth Airport are required to satisfy the requirements of the Airports (Environment Protection) Regulations 1997. The greatest potential source of pollution related to airport operations has been identified as oil and fuel spills during aircraft servicing and refuelling. Pollution control processes are discussed in more detail in the Draft Perth Airport Environment Strategy <strong>2009</strong>. Hydrocarbon and sediment interceptors are specified on all apron construction projects that provide for aircraft refuelling. All recently constructed aprons include these measures. Hydrogeology Perth Airport is located over the Cloverdale Groundwater Flow System. The groundwater flows generally westward towards the Swan River. In wet winter months specific areas of the airport estate become inundated or water logged. As the groundwater within the airport is relatively close to the surface in most zones there is variability in soil conditions and a seasonal change experienced. As a result site specific assessment of groundwater conditions is considered essential when proposed development is either impacted by, or is likely to impact, the groundwater. 92

AIRCRAFT NOISE AND AIRSPACE PROTECTION About this Chapter Noise from aircraft approaching and departing Perth Airport and from aircraft operations on the airfield is an unavoidable impact from the provision of air services. Although aircraft and engine technological improvements continue to result in new aircraft being quieter, the growth in both the number of aircraft movements and the size of the Perth Metropolitan Region means that some communities will continue to be exposed to aircraft noise. This chapter describes the regulatory regime relating to aircraft noise exposure around airports and the activities undertaken by Perth Airport to manage aircraft noise exposure. The chapter also describes the aircraft noise exposure that is projected to exist in the next 20 years and for the ultimate development of Perth Airport using accepted Australian standards and industry practice. The chapter also describes measures that are used to ensure that safe operation of aircraft is not compromised by developments that might occur in the vicinity of Perth Airport. 11.1 Aircraft Noise Management Consultation with community representatives is an essential element in aircraft noise management, both to ensure Perth Airport is aware of community experience and concerns and to ensure that inappropriate developments do not occur in areas that are susceptible to aircraft noise now and in the future. A Noise Management Consultative Committee has operated at Perth Airport since 1999. The Committee has overseen the development and implementation of an Aircraft Noise Management Strategy for Perth Airport. Following implementation of the Noise Management Strategy the Committee has focused on monitoring the effectiveness of the strategy and identifying improvement opportunities. The Committee includes representatives from Perth Airport, Local Governments, State and Federal Government Departments, Federal Members of Parliament, airlines and community groups. The key issues addressed by the Committee include: • monitoring land use planning in the vicinity of Perth Airport; • monitoring existing and reviewing proposed Noise Abatement Procedures; • monitoring and reviewing aircraft engine ground running activity; • monitoring and reviewing the existing noise monitoring program; • reviewing, through a consultative environmental assessment process, any changes to airspace management procedures being undertaken by Airservices Australia; • informing existing and prospective owners of properties of aircraft noise impacts; and • facilitating the education of community about aircraft operations. Committee achievements to date have included: • prepared the N65 Contours Chart showing annual average day aircraft noise events louder than 65 decibels; • prepared the Measured N70 Contours Chart showing actual average aircraft noise events louder than 70 decibels; • considered and supported the endorsed 2007 ANEI for Perth Airport; • considered and supported the ultimate practical capacity for ANEF produced in <strong>2009</strong> for Perth Airport; and • provided community information and education via the preparation of a publication directed at insulating homes from aircraft noise entitled Reducing Aircraft Noise in Existing Homes. In addition to supporting the ongoing operation of the Noise Management Consultative Committee, Westralia Airports Corporation has also prepared an Aircraft Noise Management Policy which confirms WAC’s commitment to ongoing noise management. The key commitments reflected in the policy include: • manage and work with the Noise Management Consultative Committee to implement the Committee’s strategy; 93
