Bunbury Airport Expansion Project, Bunbury,

Western Australia

EPBC 2013 / 6872

Compliance Assessment Report

for the

Department of the Environment

1 January 2015 to 31 December 2015

The City of Bunbury (‘the Çity’) is the Proponent for the Bunbury Airport Expansion project located in

Bunbury, Western Australia (Figure 1). This project has undergone assessment under the Environmental

Protection and Biodiversity Conservation Act 1999 (EPBC Act) and its implementation is subject to meeting a

range of environmental conditions under the federal environmental approval (EPBC 2013/6872). The

environmental conditions apply to both the airport expansion area, and a separate environmental offset

site.

This project has also undergone assessment under the Environmental Protection Act 1986 (WA) and its

implementation is subject to meeting a range of environmental conditions given in the approved native

vegetation clearing permit CPS 5589/1.

This is the first of five required Compliance Assessment Reports (CAR) prepared for the conditions given in

EPBC 2013/6872. It provides the status and compliance of project activities against each condition and its

preparation was required in Condition 8 that states:

By 31 March of each year after commencement of the action, the approval holder must

publish a report on their website addressing compliance with each of the conditions of this

approval between 1 January and 31 December of the preceding year, including

implementation of the EOMP as specified in the conditions. Documentary evidence providing

proof of the date of publication must be provided to the Department at the same time as the

compliance report is published. The compliance reports must remain on the website for a

minimum of 12 months (beginning on the date of publication). Potential or actual

contraventions of the conditions of approval must be reported to the Department in writing

within 2 business days of the approval holder becoming aware of the actual or potential

contravention. All contraventions must also be included in the compliance report.

Any remaining commitments will be implemented progressively over time by the City and reported on in

subsequent reporting periods.

Project Background and Environmental Approvals

The Bunbury Airport Expansion Project provides for the future construction of 23 hangars and a rescue

helicopter base at the Bunbury Regional Airport.

The project required the clearing of 2.13 ha of vegetation, comprising of 1.43 ha of native vegetation and

0.7 ha of introduced pine trees. Site surveys identified the presence and potential habitat of

Commonwealth and State listed threatened western ringtail possums, Carnaby’s, Baudin’s and Forest Red

tailed Cockatoos within the clearing impact area.

The project was referred to the Department of the Environment (DotE) and the Department of

Environmental Regulation (DER) in view of the impacts on native vegetation and specially protected fauna

species in the project area.

Both departments issued approvals for the clearing of vegetation subject to conditions including

implementation of agency specific environmental offset management plans. Key to both of these offset

plans was the securing and management of 11.83 ha of native bushland for conservation purposes in

perpetuity within Crown Reserve R40664, SW Highway Bunbury.

The DER issued a clearing permit (CPS 5589/1) on the 31 July 2014 and the DotE issued a clearing approval

(EPBC 2013/6872) on the 15 January 2015.

The project clearing action commenced on 30 March 2015 in accordance with the clearing approvals.

Copies of the federal and state annual CARs and relevant environmental management plans can be

accessed on the City’s website: http://www.bunbury.wa.gov.au/Pages/Environmental-Approvals.aspx



Current status of the project

During this reporting period the Bunbury Airport Expansion Project was completed providing the necessary

infrastructure (taxi ways, roads and underground utilities etc.) for the construction of the Bunbury rescue

helicopter base and additional hangars. The scheduled activities associated with the environmental offset

site were also commenced. An overview of these activities is provided below:

1. Implementation of the Airport Expansion Project

• The clearing of 2.13 hectares of native vegetation within the airport expansion area commenced on

30 March 2015 and was completed on 10 April 2015 with no known injuries or deaths to Western

Ringtail Possums or other native fauna.

• A fauna spotter was engaged to manage native fauna during clearing operations and to supervise

the extent of clearing.

• A fence was installed around the perimeter of the project area.

• Dieback and weed hygiene measures were implemented during clearing and development

operations.

2. Implementation of the Environmental Offset Site within Reserve 40664 SW Highway

• Undertook one feral animal monitoring episode

• Undertook one feral animal control episode

• Installed four gates to manage the spread of dieback

• Mapped location of Pampas Grass and other priority environmental weeds

• Controlled Pampas grass within the offset site area

• Surveyed rubbish within the offset area.

• Commenced process to obtain a Class A classification and Regional Open Space reservation for the

offset area.

• Monitored domestic dog on-lead compliance within the offset

• Monitored unauthorised vehicle access within the offset

Compliance issues:

The City advises that there some non-compliance issues to report in this period. These compliance issues

together with proposed remedial measures are summarised in table 1 below and discussed in further detail

in tables 2 and 3. The City notified the DotE of these compliance issues in November 2015.

The reasons for the forecast partial completion include a combination of the reduced timeframe available

for completing activities under the first reporting period owing to the delayed commencement of the

vegetation clearing (i.e. only nine months are available as opposed to the 12 months originally intended),

unforeseen delays with the advertising and award of a separate contract for the management of feral

animals and installation of gates at the offset site and administrative oversite over the required frequency

of site inspections.
