Chief Executive Officer’s Report

An important milestone was achieved during WACs second year as Perth International Airport lessee the year when approval was received from the Minister for Transport and Regional Services for the airport’s five year Environment Strategy and Master Plan. This approval followed a consultative process that saw the Environment Strategy and Master Plan subjected to considerable public scrutiny.

The Environment Strategy documents our commitments to the environmental management of the Perth International Airport. Since approval of the Strategy in August 1998, we have been working to implement an environmental management system which helps provide a framework for the way we identify and manage the environmental issues at the airport. All of the commitments made in the Strategy as well as new issues that have arisen throughout the year have been incorporated into our environmental management system.

A number of initiatives, in line with the stated commitments in the Environment Strategy, have been embarked upon in the past year. Of major significance has been the formulation of the Noise Management Committee involving State, Commonwealth, Industry and Community representatives. The Committee will investigate aircraft nois e issues and prepare a Strategy for submission and approval by the Federal Minister for Transport and Regional Services.

The extensive land area of Perth International Airport introduces many issues of land management. Measures have been introduced to minimise illegal access and inappropriate usage of the landholdings. The preparation of the land management plan commenced with substantial assistance from community and government stakeholders, and the establishment of a stormwater monitoring program has produced positive results.

A handbook for tenants is currently being prepared and will provide advice and information to tenants to assist in the preparation of their environmental management strategies. It will provide comprehensive information advising of the statutory obligations and requirements and will assist in improving overall environmental performance and awareness.

As a major customer service initiative, WAC launched a new web site to provide airport customers and the community with access to information on the services and facilities as well as environmental management reports such as this.

The management and staff of WAC look forward to the next century with great confidence that our airport will grow from strength to strength – realising its vision to become the most successful airport business in the world.

Hastings Funds Management Limited manages PAPF and AIF, giving it a total equity interest of 34.4 per cent. Through AIF, Hastings has a number of investments in airports, electricity, gas, toll roads and rail.

AGI has 70 years experience in the aviation industry, including airport management, development and airline services, and has operations at 29 airports around the globe.

The Airport Perth International Airport is the international and regional gateway to Western Australia. It is one of Australia’s closest airports to South East Asia, Europe and Africa, and is located approximately 12 kilometres from Perth’s central business district on a 2105 hectare site.

The airport ranks fourth in passenger traffic volume in Australia, and is the principal international, domestic and regional gateway to Western Australia for commercial aircraft and airfreight.

The Facilities The primary aviation related facilities at Perth International Airport include:

• a three-runway system capable of handling any existing or planned intercontinental commercial aircraft;

• an international terminal building with five aerobridges and seven aircraft stands; • a domestic terminal complex with a total of five aerobridges, 18 aircraft standoff

positions and three freighter positions; • air freight, aviation fuel and in-flight catering facilities; • aircraft maintenance hangars and associated infrastructure; • general aviation and corporate facilities; and • air traffic control facilities.

The People As at the 30 June 1999, WAC employed 93 staff members in a variety of business units (figure 2). These business units cover a wide range of activities, including:

• airport operations; • aeronautical infrastructure maintenance and development; • property and retail; • car parking; • electricity reticulation; and • airport consultancy.

Figure 2 WAC Organisation Chart

Master Plan The Minister for Transport and Regional Services approved the Perth International Airport Master Plan on 18 May 1999.

The Master Plan was produced following an extensive consultation and public review period and was prepared in accordance with the requirements of the Airports Act 1996.

Although the Airports Act only requires a 20-year plan, WAC also decided to include a plan of the airport at its ultimate development, which expected to be reached towards the middle of the 21st century.

The primary objectives of the Master Plan are to:

• ensure the provision of aeronautical facilities to meet the requirements of civil aviation users; • guide the development of existing and proposed airport land users and facilities; • propose a development philosophy that is compatible with State and local planning objectives; • provide for future demand within acceptable social, economic and environmental constraints; and • incorporate issues raised through consultation with airport stakeholders. WAC is now to embark on the next stage of the airport planning process with the preparation of detailed development and strategic plans for the dedicated areas identified by the Master Plan.

Aeronautical Development The development of aeronautical infrastructure to support the growth of aeronautical activities at Perth International Airport is a major priority for WAC. During the past year the major aeronautical development project was the expansion of the Qantas domestic terminal and associated facilities. Qantas expanded their existing domestic terminal building at a cost of approximately $7M and WAC provided infrastructure facilities under the terms of Qantas Domestic Terminal Lease at a cost of $2M. The Qantas domestic terminal expansion project included the construction of engineering maintenance facilities, valet facilities, check-in areas, departure lounge areas, covered walkways and retail expansion and redevelopment. The WAC infrastructure project to support the Qantas domestic terminal expansion included the construction of an aircraft parking apron to accommodated aircraft varying in size from B747 to BAe 146, taxilane lighting, taxiway, taxiway lighting, drainage and floodlighting facilities.

Property Development The Perth International Airport development strategy is based on seven precincts with allocated land use categories. The precincts have been configured, sized, and located to achieve the following objectives:

• maximise their respective exposure to major existing and projected regional networks;

• allow flexibility for future subdivision and internal roadway layouts;

• accommodate existing physical boundaries such as major roadways; and

• compose land with high conservation and heritage priories into large contiguous areas.

Each precinct has been designed to support the planning and real estate value of surrounding precincts and further support the airport's image as a global transportation and logistics centre.

Following approval of the Master Plan in May 1999, WAC embarked on the next stage of the planning process which will involve the preparation of detailed concept plans and guidelines for development of precincts.

This process will involve extensive consultation with all stakeholders (government and community) and is due for completion in mid-2000.

Terminal Development The Master Plan specified that domestic terminal operations will need to be relocated to the current international precinct by the year 2018. As a result, structure planning of the International Terminal and Air Freight Precincts commenced in 1998/99. This work examines how the area will grow from now to the time when the terminals are consolidated and included preparation of a use plan for the area with timelines and forward projections of requirements for aircraft parking, aerobridges and active contact gates.

ENVIRONMENT POLICY The Westralia Airports Corporation recognises the importance of maintaining and enhancing the quality of the environment. In developing and managing Perth International Airport we will establish and maintain a system which endeavors to achieve best practice and:

• Identifies, prevents, controls or reduces significant environmental impacts associated with airport operations.

• Complies with relevant environmental legislation and regulations.

• Sets, in consultation with Commonwealth, State and Local authorities and the general public, specific environmental objectives and targets to reduce our environmental impact and prevent pollution.

• Continually measures, monitors, reports and improves upon the environmental performances defined by our objectives and targets.

• Responsibly manage resources and wastes to enhance sustainable development.

• Promotes WAC commitment to the environment, to its employees, tenants, customers and neighbours .

The Environment Policy statement has been formally adopted by the Board of WAC and issued over the signature of the Chief Executive Officer.

The Environmental Framework

WAC wants to improve environmental performance at the Perth International Airport. A strategic framework has been developed that shows how this vision is to be achieved. A set of five new objectives have been developed from integrating the original 17 objectives from WACs Environment Strategy, a document that sets out the basic principles for environmental management at the airport until 2003. The integration of the original objectives simplifies and clarifies our vision for the future. The new objectives are listed in the figure below and are repeated in each of the following sections showing the link with the original objectives from the Environment Strategy.

The framework is intended to support the Environment Policy but to date these are currently unaligned. The Policy is to be reviewed in late 1999 to more clearly represent the new framework of environmental management at the airport.

• To establish clearly defined procedures for dealing with accidents and emergency situations and to ensure that staff are adequately trained to apply these procedures

• To maintain procedures for monitoring, measuring and auditing the key characteristics of Perth International Airport’s operations which could have a significant impact on the environment

• To establish a system for investigating and documenting non-conformances and for implementing corrective and preventative actions

• To establish and maintain procedures for periodic auditing of the environmental management system, which will determine whether it conforms to planned arrangements and whether it has been properly implemented and maintained

• To keep environmental records in such a manner that they are legible, identifiable and traceable to the activity, product or service involved and are readily retrievable

Systems

Environmental Management System Principle

In late 1998, WAC began to restructure its environmental management system. The ISO14001 framework was chosen for the restructure and principal procedures for the system were developed over the course of the year. The key elements of the system that have been completed to date are the Policy, an initial environmental review highlighting significant environmental issues, setting objectives and targets for the these issues, development of draft environmental procedures, and monitoring strategies.

Initial Environmental Review

An initial environmental review was conducted in October 1998. The review consisted of interviews with staff members as well as identifying all issues raised by previous audits, reviews and research, including information in the WAC Environment Strategy. The significancy of issues was determined according to a ranking criteria designating issues into four categories – low, moderate, high and critical (see opposite page for ranking criteria). Accountabilities were assigned to the issues, objectives and targets set and task lists (with deadlines) generated.

Data Management

Data on environmental issues at Perth International Airport are held in a number of different systems. An Environmental Data Management database was developed in late 1998 to store data on environmental issues (including objectives, targets, action plans, deadlines, accountabilities and progress information), contaminated sites, status and location of significant flora and fauna, incident reports and complaints/enquiries. Electronic data on soil and water quality is stored in a ChemPoint Database. An electronic and hard copy filing system exists for storing supporting documentation on issues, incidents, complaints/enquiries as well as environmental procedures, environmental management system information, tenant permit information and training packages. The procedures, training packages, environmental management system documentation and permit information will be placed on an internal Intranet system which is due to implemented in November 1999.

WAC Staff Standards and Guidelines

As a requirement of the ISO14001 environmental management standard, a set of procedures were developed for employees and contractors of WAC in 1998/99. The procedures have been separated into standard operating procedures and environmental management system procedures. Many of the procedures are still in draft format and are in the process of being distributed to relevant staff for comment prior to finalisation and implementation in 99/2000. The procedures will be placed on the WAC intranet site when developed so all employees are able to access the information as required.

Standard Operating Procedures The standard operating procedures were developed to enable employees to consistently and adequately manage their work tasks where there may be a risk of impacting the environment.

The procedures developed to date are:

§ Management of Non-Hazardous Wastes (draft)

Developed to reduce the level of non-hazardous waste levels being disposed to landfill and to encourage the philosophy of reduce, re-use, recycle in the workplace.

§ Management of Hazardous Materials and Wastes (draft)

Developed to ensure hazardous materials and wastes are correctly, stored, handled and disposed so as to minimise risk to human health and the environment.

§ Procurement of Plant, Equipment and Materials (draft)

Developed to ensure that OH&S and environmental protection are considered during the procurement process.

§ Tracking of Chemicals (draft) Developed to minimise the risk of “unsafe” chemicals being bought, stored and disposed of by WAC staff.

§ Contractor/Third Party Controls (draft)

Developed to ensure WAC staff that administer contractors are responsible for ensuring the contractors are aware of their OH&S and environmental responsibilities.

§ Minimising Discharges to Air, Soil and Water (draft)

Developed to ensure impacts on the environment are minimised by designing or placing controls on operations (WAC and tenants).

§ Fuel spill response* Designed specifically for managing fuel spills on apron areas. § Airport Emergency Plan* Designed specifically for a major incident that may place the

operation of the aerodrome under threat. * existed prior to 1998/99 but were reviewed to ensure compliance with the ISO14001 standard

WAC Environmental Management System Procedures

As a requirement of the ISO14001 environmental management system standard, procedures were developed and implemented during 1998/99. These include such procedures as:

• Environmental Data Collection and Management

Designed to explain the process of collecting regular environmental data and how it is managed.

• Record and Document Control Designed to explain how environmental records are stored and reviewed.

• Dealing with Environmental Issues

Designed to explain the process utilised to identify, rank, register and report on environmental issues.

• Audit, Review and Verification (draft)

Designed to ensure WACs EMS is reviewed internally and externally and tenants are audited on a regular basis.

• External Communication Designed to clearly define the procedure for dealing with environmental issues from external parties.

• Internal Communication and Employee Awareness Training (draft)

Designed to define the mechanisms for internal communications and training of staff.

10

Tenant Standards, Guidelines and Procedures

The WAC Leasing and Development Guidelines for current and prospective tenants were reviewed in late 1998 to update information on the environmental management requirements of a tenant at Perth International Airport. The major change to the guidelines were the inclusion of a approvals process flowchart and the requirement for proponents of developments/redevelopments that are likely to pose a risk of impact on the environment to submit an Environmental Management Plan (EMP) to WAC within 3 months of signing a lease or with a Permit to Commence Works application.

A sample set (digital and hardcopy) of environmental procedures has been developed for commercial/industrial tenants. The procedures are intended as guidance for tenants to develop their own procedures or for adoption “as is” if preferred. The procedures will be distributed to tenants in late 1999.

Precinct concept development planning commenced in mid-1999. A task force of consultants have been contracted to prepare concept designs and guidelines for precincts identified in the Master Plan and Environment Strategy. An environmental consultant has been appointed to work with the task force to ensure developments are designed in the most environmentally sensitive way that is economically achievable, and the development guidelines reflect these requirements. The designs and guidelines are currently scheduled for completion in August 2000.

NEW OBJECTIVE - PARTICIPATION To encourage employee, tenant and community involvement in the management of environmental issues. eg employee and tenant awareness, training, communication, stakeholder involvement

Objectives listed in The Environment Strategy

• To establish environmental management teams and committees

• To establish and maintain environmental objectives and targets of each relevant function and level within the organisation

• To ensure that staff are aware of their environmental responsibilities by implementing appropriate training and awareness programs for existing and new staff

Participation

Over the past year, WAC has worked to develop its environmental management systems and processes. The focus will shift in the next 12 months to strengthening the culture of environmental awareness and responsibility amongst WACs employees, contractors and tenants. Training in environmental issues is essential to meet the objectives of our Environment Policy. The idea of encouraging the participation of stakeholders, employees, contractors and tenants to be involved in the management of environmental issues, requires the education of people in such a way as to foster an appreciation for the environment and the objectives of the corporation. The key mechanism for encouraging participation is the provision of information.

Corporation Within the organisation during the reporting period there has been no formal procedure in place for information distribution other than through monthly reports for the Executive Group.

During the 1999/2000 year a number of mechanisms will be implemented to encourage employee and contractor participation in environmental management. The main avenue will be the availability of environmental information through the establishment of an intranet web page.

A number of information sessions will also be held to update employees and contractors on the progress of the Land Management Plan, the findings of the tenant auditing program and any other major issues that may be of interest to employees and contractors (ie finalisation of Perth’s Bushplan).

Tenants A handbook titled “Protecting our Environment – Information for Tenants” was prepared in early 1999. The handbook couples as a mechanism for informing tenants of their environmental obligations as well as providing information that may require for improving the environmental performance of their businesses. The handbooks are currently being printed and will be distributed to tenants in late 1999.

In addition to the handbooks, some of the major environmental risk tenants will undergo environmental audits in 1999/2000 which will necessitate the involvement of tenants in the process and provide an avenue for information transfer.

Community and Stakeholder Involvement WAC consults with the community on environmental issues such as noise, bushland management and water quality. WAC are involved in a number of committees that are avenues for fostering good relations with community groups and other stakeholders.

Informal meetings are held with community representative groups, such as the Urban Bushland Council or the Friends of the Perth Airport Bushland Group on an as is required basis.

WAC established the Noise Management Committee in May 1998 to ensure appropriate consultation with both representatives of surrounding communities and the aviation industry in the development of a Noise Management Strategy. The committee had its first meeting in May 1999, and members include representatives from WAC, the airlines, together with Local, State and Federal Government departments.

WAC have been working with the Belmont-Victoria Park Catchment Group and the Friends of the Perth Airport Bushland Group to prepare a joint submission for funding from the Swan Catchment Urban Landcare Program in order to commence weed control around Munday Swamp (Precinct 7 Conservation Zone). The outcome of the submission will not be known until mid-October 1999.

In the 1999/2000 year, WAC intent to prepare a community consultation strategy for environmental issues. Agreement for the strategy will be sought from the key community groups which have been identified to date as the Friends of the Perth Airport Bushland Group, the Urban Bushland Council, The Hazelmere Progress Association and other interested residents groups. The strategy will aim to identify the key times for communication with community groups on various issues. This will become particularly important as WAC move into the development phase of precincts defined in the Master Plan and Environment Strategy.

Responsibility

Corporation Business Planning

Integrating environmental objectives into business planning is essential in allocating resources and accountability. Environmental management has been incorporated into business planning since WAC has been operating the Perth International Airport. Similar to the Environment Policy, the environmental objectives that have been incorporated into business planning are unaligned with the new framework of the environmental management system. This is to be addressed in 1999/2000 when the 2000/2001 business plan is being prepared.

Position Descriptions and Performance Review For WACs environmental programs to succeed, all employees and contractors need to understand their roles and responsibilities. In early 1999, WAC embarked on developing a new performance management system for staff. The new system incorporates OH&S and environmental performance as key criteria for all staff to be measured against.

Position descriptions currently do not contain specific environmental responsibilities and this has been highlighted in our environmental management system as an issue to be addressed in 1999/2000.

Training

All new employees at WAC undergo an induction on their first day of employment. The new employee is provided with an orientation manual which contains information on corporate policies and procedures, employee requirements etc. An environmental management section has been produced for inclusion in the manual and is likely to be included in the next set of manuals printed off in 1999/2000.

As a requirement of our environmental management system, draft procedure titled “Internal Communication and Employee Awareness Training” has been produced and incorporates a section on Induction Training. It is proposed that all new employees undergo a 2 hour training session with the Environmental Officer. The checklist opposite shows the list of topics that are proposed to be covered in the training session.

Tenants Leases, Permits and Contracts

It is standard procedure at WAC for all new leases, Permits to Commence Works and contracts established by WAC with tenants and other parties to incorporate environmental clauses/conditions that clearly outline the requirements and responsibilities of the tenant/contractor. If the proposed use of a site to be developed meets the requirements of a prescribed premise under the WA Environment Protection Act, WAC routinely consult with the Department of Environmental Protection (DEP) over suitable conditions (usually standard Licence to Operate conditions) to incorporate in either a lease document (if a new tenant) or a Permit to Commence Works for an existing tenant. It is WACs intent to be as consistent as possible with the requirements of the State DEP so as not to encourage unfavourable tenants/operations to develop on airport land because the approvals process or constraints are less stringent.

14

A standard list that incorporates over 40 conditions/clauses has been generated over the reporting period for use in permits and lease documents. Some examples of clauses/conditions are shown below:

• All works must be carried out in accordance with your approved Environmental Management Plan.

• Quickbreak detergents only are to be used to wash plant, equipment and vehicles.

• Groundwater monitoring bores must be monitored at a maximum interval of 6 months and results submitted to WAC annually.

• All pipework is to be aboveground and on hardstand.

• Prior to entry to the airport bushland, all vehicles, machinery and equipment are to be cleaned to remove soil to prevent the spread of soil borne diseases and exotic species.

• Domestic animals, traps or firearms are not to be brought onto airport land. • Noise levels from operations on site are required to comply as a minimum with the

Airports (Environmental Protection) Regulations 1997. All reasonable and practicable measures should be taken to ensure the health, welfare, convenience, comfort or amenity of any person is not interfered with by unreasonable noise levels emanating from the operation.

• Environmentally hazardous wastes shall only be disposed of at sites approved in writing by the Department of Environmental Protection’s Waste Management Division (contact: 08 9476 7400).

• Any spill of hazardous or potentially hazardous material (fuel, oil, acid, solvent, paint, oxidants etc) must be reported to WAC on a standard Accident/Incident Form within 24 hours of the incident.

• Any person/s responsible for supervision of the works at any time is to be aware and have access to these conditions.

• Dust suppression is to be undertaken if dust levels are likely to exceed the Accepted level for solid particle air pollution as stated in Schedule 1 of the Airports (Environmental Protection) Regulations 1997.

• Whilst undertaking construction works on the site, particularly drainage works, sediment control measures must be undertaken to prevent discharges of sediment in stormwater drainage from the site.

NEW OBJECTIVE - PERFORMANCE

To reduce the impact of our operations on the environment

eg risk assessment, life cycle analysis

Objectives listed in The Environment Strategy

• To monitor, measure, control, reduce or prevent airport pollution, including that produced by tenants

• To attend to outstanding environmental issues and to maintain systems that can in the future identify and keep up to date the environmental aspects of Perth International Airport’s activities

WAC records non-compliance incidents using 4 levels

Level 1 Technical issues not involv ing a direct impact on the environment ie. failure to submit a report to government on time

Level 2 Minor near-miss incidents that do not have a direct impact on the environment ie fuel spills on the apron

Level 3 Incidents resulting in a short term impact on the environment

Level 4 Incidents resulting in potentially serious consequences and/or a long term impact on the environment

Performance

Compliance WAC is subject to a number of environmental regulations, both State and Commonwealth. No prosecutions or fines were issued against WAC during the year.

Incidents WAC and its tenants have a diverse range of obligations, from legislation, licence and lease conditions and permits to commence works and development approvals.

WAC categorise incidents into four levels ranging from level 1 (technical non-compliance with lease, regulations etc) that do not involve a direct impact on the environment through to level 4 incidents which result in serious long term environmental consequences. Approximately 121 incidents were reported or detected by monitoring during the 98/99 reporting period. Of these, 113 were fuel and oil spills (totalling 1308L) resulting from re-fuelling activities on the domestic and international apron areas. This compares to 138 incidents totalling 2137L in 1997/98. Fuel/oil spills on the apron are categorised as level 2 incidents as they do not result in a direct impact on the environment.

Level Area Incident Date Corrective/Preventative Action

3 Newburn Bushland

Approximately 200ha bushland burnt following the deliberate torching of a stolen car

January 1999 Chubb Security were commissioned to patrol bushland areas on weekends prior to a gate being installed in July 1999. Weekly inspections of the security fence were implemented to repair fences as required. .

Research into the rationalisation of fire-tracks and weed management strategies to reduce fuel loads in the bushland has commenced.

2 Qantas Freight Terminal

Liquid was found leaking from a package containing radioactive material

March 1999 Isolation zone established and secured. Liquid collected and analysed by Department of Health. Chemical removed from site.

3 Pioneer Road Services

Noise, dust, light and odour emissions affecting local residents

Ongoing since site commissioned

An action plan was established by PRS and is currently being implemented. Issues are to be reviewed as actions implemented.

3 Domestic Apron

Approximately 20L oil disposed of by unknown persons in an open unlined drain

May 1999 Tenants with operations adjacent to the drain were notified of the incident and informed that oil disposal to drains was not an acceptable practice. The drain has been monitored and to date there has been no recurrence.

3 Domestic Apron

Hydraulic oil from Ansett pallet lifters found to be draining onto nearby soil.

June 1999 Ansett were notified of the incident and requested to implement preventative actions. To date the issue has not been resolved.

3 Newburn Bushland

Tree felling under a power line occurred in bushland listed on the Interim Register of the National Estate by Western Power.

May 1999 Western Power were contacted in regards to the matter and informed of the listing of the area on the Interim Register of the National Estate and the correct protocol to follow in the event that action is required in the area. The Australian Heritage Commission was notified of the incident.

3 Precinct 3A Approximately 4ha of vegetation was cleared by a potential tenant prior to signing of lease and without a Permit to Commence Works

June 1999 The responsible person was notified that the actions were a breach of WAC procedure and works are to cease until a lease document is signed, an approved Environmental Management Plan is developed and a Permit to Commence Works is issued by WAC.

4 AGR Joint Venture

Water quality monitoring detected levels of cadmium, copper, nickel and zinc elevated above background water quality levels and the Accepted Levels (Schedule 3) of the Airports (Environment Protection) Regulations 1997.

December 1998 AGR has conducted investigations and suspect the source of the contamination is fugitive filter cake particles from the effluent treatment plant. Bund walls surrounding the treatment and packaging areas are scheduled to be modified by 31 October 1999. It is anticipated that if the water quality does not improve following the planned modifications, AGR wish to conduct an environmental risk assessment to quantify the impact of their emissions on the receiving environment.

16

Water Quality WAC implemented a quarterly surface water quality monitoring program in December 1998. Monitoring locations comprised 4 background (Sites 10 - 13), 5 discharge (Sites 1 – 5) and 6 miscellaneous locations (Sites 6 – 9, 12, 15 - 21).

Two sampling runs were conducted within the reporting period. A sampling run was conducted in December 1998 and another in late May 1999 following the first major rainfall period after the summer period. The first quarter 1998 sampling run was cancelled as a result of a lack of surface water flow. Water was evident in many of the drains during this period however much of this was considered to be surface expressions of groundwater rather than surface run-off.

Sampling Water sampling at Perth International Airport is conducted in accordance with the AS/NZ Standard 5667 Water Quality Sampling – Guidance on the design of sampling programs, sampling techniques and the preservation and handling of samples.

Analysis Samples are analysed at laboratories that are NATA registered for the specific type of analysis conducted.

Data Management and Reporting All data from water quality monitoring is entered into WACs Chempoint database, A quarterly monitoring report is produced containing results of any monitoring conducted in that quarter and follow up actions from previous reports.

Many of the locations selected as appropriate sampling locations were dry during both the sampling runs and no samples were collected. Where a location had two samples collected and one of these was a non-detect result, the detection limit was substituted to provide a median result. Many of the results shown in the table opposite are therefore considered conservative.

All samples collected were analysed for total petroleum hydrocarbons (TPH) in both sampling runs, however all the results were below detection limit and were not included in the table of results.

The results shown in the table opposite show that in most cases the background water quality exceeds the Airports (Environment Protection) Regulations Accepted Levels for most parameters and airport run-off does not significantly contribute to the contaminant loadings discharging from the site. An exception to this is the water quality in the southern main drain which is impacted by discharge water from the Australian Gold Refinery Joint Venture (AGR). This has been raised as an incident and is discussed in further detail on page 15 of this report.

Chromium, arsenic or mercury were not detected in samples from any locations. Zinc was elevated above the Airports (Environment Protection) Regulations Accepted Levels at all locations whilst surfactants (MBAS) were potentially in non-compliance with the Regulations as a result of the laboratory being unable to reach a detection limit lower than the Accepted Level of 0.05µg/L.

Land Management Development of a Land Management Plan for the Perth International Airport commenced in early 1999. It was stated in the Environment Strategy that separate land management plans were to be prepared for each precinct at the airport, however, it has been decided to incorporate all the precincts into one management plan. The completion deadline of December 1999 has been extended into mid-2000 as a result of a number of issues. Firstly is the decision for WAC to fully consult with stakeholders and community groups throughout the development of the draft plan and then at completion of the draft plan. Secondly, is the need to align the land management plan with the precinct development plans and guidelines, which are due for completion in mid-2000.

As a component of land management, research into the rationalisation of firebreaks in the Perth Airport Bushland has commenced. The Fire and Emergency Services Association of WA have been assisting WAC with this project. A report is currently being prepared by consultants on the recommendations for rationalisation of firebreak tracks in the airport bushland. The intent of the rationalisation is to provide accessible pathways for fire fighting crews in the event of a fire and also to compartmentalise the bushland in order to ensure adequate representation of the bushland in the event that any one compartment is burnt out. The compartments are to be prioritised so fire-fighters are aware of bushland compartments which may need protection as a priority in the event of a fire. The report is to be provided to community and stakeholder groups for comment prior to its finalisation (November 1999).

Western Swamp Tortoise translocation negotiations have continued with CALM during the course of the year. A hydrology study was commissioned in June 1999 to investigate the potential impact of future development on the groundwater hydrology in the northern region of the airport, an area identified by CALM as containing potentially suitable habitats for the translocation of the Western Swamp Tortoise. The results of this are expected in November 1999. It is anticipated a decision on the translocation of the Western Swamp Tortoise may then be able to be made provided further research is not required.

18

In early 1999, number of research topics were identified by WAC in association with Murdoch University as being potential projects for students. To date one of the projects has commenced and is due to be completed in November 1999. The focus of the project is weed prioritisation and management in the Newburn bushland and around Munday Swamp. Results of this work are expected to be able to be incorporated into the Land Management Plan.

In February 1999, WAC conducted a major waste removal exercise in the Newburn bushland area, clearing out general waste and car bodies that had been illegally disposed of in the area.

Control of veldt and love grasses in the bushland area affected by a fire in January 1999 (see page 15) commenced in May 1999 at the advice of CALM. Approximately 15 ha were treated by spot spraying with a grass selective herbicide (Fusilade).

A major cause of environmental damage (waste disposal, erosion, fire, weed distribution etc) in the Newburn bushland has been the result of illegal access by the community. The leases of two rural tenants in the bushland area expired in August 1999, enabling WAC to restrict access into the area by the installation of a gate. The presence of four-wheel drivers and trail bike riders continues to be an issue with security fencing being regularly vandalised to provide access into the area. WAC will continue to address this issue into 1999/2000.

Waste Management Waste management at Perth International Airport is consistent wherever possible with current national and state based policies and codes of practice. WAC encourages waste minimisation practices with tenants, however the control of WAC over the tenants practices are limited to regulatory requirements, and conditions in lease agreements and Permits to Commence Works. Tenants are not required to report their environmental management practices to WAC and as such WAC does not have data available on the volumes of solid waste generated and methods of disposal from tenants at the airport.

In 1999/2000 WAC are initiating on a tenant auditing program. It is through this process that WAC anticipates to assess the waste management practices (amongst others) of tenants and determine any appropriate remedial actions that tenants may be required to implement.

Contaminated Site Summary Joint Operator Storage Facility During the year several additional groundwater monitoring bores were installed around this site to enable the extent of a fuel contaminated groundwater plume to be delineated. WAC is awaiting the results of this monitoring and a remediation/management strategy from Air BP.

Airservices Australia Airservices Australia removed an underground storage tank in January 1999. Sample results indicated there was no soil contamination from around the tank.

Hydrocarbon contaminated soil was reported to have been removed from around the Aviation Fire and Rescue Service’s fire training ground and landfarmed during the reporting period, however WAC have not yet received an assessment/remediation report or validation results of any work conducted.

Australian Gold Refinery Joint Venture Pty Ltd Groundwater monitoring has continued in 1998/99 following the discovery of a leaking waste process storage tank in mid-1998. WAC are awaiting the results of this monitoring and a

remediation/management strategy.

Cultural and Natural Heritage Update A number of native title claims which cover parts or all of Perth International Airport are proceeding at various stages through the native title process. Native Title claim WC 95/9 has been referred to the Federal Court.

The 510ha of airport land previously listed on the Interim Register of the National Estate was listed on the Register of the National Estate.

Another Declared Rare Flora was identified at Perth International Airport in 1998/99. Macarthuria keigheryii is located in Precinct 5 which is a WAC conservation area. Both DRF known at the airport are located in this Precinct.

Aircraft and workshop washdown bays were identified in the Environment Strategy as potential sources of stormwater contamination but to-date, stormwater quality monitoring downstream of these locations has not shown any evidence that the operation of these facilities causes any environmental impact.

A risk assessment was commissioned in June 1999 to assess the risk of a major spill on the International Terminal apron resulting in an impact on the environment. The results of the study are due in October 1999.

Air Quality In 1998-99, WAC commenced monitoring the levels of greenhouse emission produced from its activities. The Perth International Airport consumed 45034 MW/h electricity producing net greenhouse emissions of 46.4kt CO2 equivalent. The use of fuel for operation of generators and WAC fleet vehicles resulted in the production of 0.51kt CO2 equivalent. Clearing of vegetation for development produced 0.4kt CO2 equivalent whilst the bushfire in January 1999 produced 18.6kt CO2 equivalent.

WAC routinely place controls on construction activities to minimise air emissions through Permits to Commence Works and lease documents where the operation of facilities is likely to result in air emissions. To date there are two tenants that monitor their air emissions – one voluntarily and one is obligated under conditions in a Permit to Commence Works.

The most significant contribution WAC made towards improving air quality during 1998/99 was the conversion of electricity supply from Western Power to Goldfields Power Pty Ltd in November 1998. The conversion is estimated to result in a 1.5% savings on greenhouse gas emissions per year. Based on 1997/98 electricity figures this will result in greenhouse emission savings in excess of 0.66kt CO2 equivalent.

Noise A feature of the approved Perth International Airport Master Plan is the publication of forecasts of the future noise impact of aircraft arriving and departing the airport. This information is used by local and State Governments to determine appropriate land uses around the airport.

WAC has also initiated a process to prepare a new noise management strategy, which will seek to achieve reductions in noise impacts.

20

The Noise Management Strategy may include noise abatement procedures (airborne and ground running), land use planning procedures, reporting of noise events/ noise complaints, and a process to assist mitigation of aircraft noise. The strategy will consider operational safety and efficiency, as well as economic aspects of airport and airline operations.

At Perth International Airport, Airservices Australia currently has four permanent Noise Monitoring Terminals (NMT) located at Cannington, Redcliffe, Greenmount and Guildford. The NMT at Cloverdale has been de-activated and removed, and a new site for this terminal is yet to be decided by Airservices Australia.

During the 1998/99 reporting period, Airservices Australia received 1287 (ave. 107/month) noise complaints in relation to aircraft flight operations at Perth International Airport. This compares to 602 complaints (or ave. 50.2 per month) for the previous year. The graph below shows a rise in complaints for each month compared to the previous year. This

was largely brought about by the media interest in the Master Plan with a concentrated negative campaign by one local government council in August 1998. This attention heightened the public’s awareness of aircraft noise issues.

On-site aircraft noise arising from operations such as ground running is managed through the aircraft engine ground running management plan. The time and power settings as well as the locations for engine ground running are set by the plan. Over the period July 1998 to June 1999, 55 dispensations for ground running outside the restrictions were granted.

Issue: Management of on-airport noise Rank: High Tasks Due Date Status Comments Prepare a management plan for on-airport noise sources - Completed A procedure for Engine Ground Running currently exists at the airport.

Hazardous Materials Very few hazardous materials are utilised by WAC at Perth International Airport. The Grounds Maintenance section utilises pesticides largely for weed management in garden beds, some bushland areas and around airport lighting. WAC own and operate 7 underground storage tanks which are in the process of being licensed as required by the WA Dangerous Goods Regulations 1992.

A complete inventory of chemicals stored by WAC was conducted in April 1999. The inventory is conducted bi-annually and used to update a Chemwatch database.

A procedure has been developed to ensure OH&S and environmental approval are obtained prior to the purchase of non-approved chemicals by WAC staff and contractors. This will ensure chemicals that pose an environmental or safety risk can be fully evaluated and if necessary replaced by an alternative chemical. This procedure will be implemented in 1999/2000. As mentioned previously, major risk tenants will be audited in 1999/2000. Hazardous materials storage, handling and disposal will be an issue that is covered in those audits. Tenants who do not comply with Regulations, lease or permit conditions will be required to implement corrective and preventative actions within a timeframe approved by WAC.
