A high priority for the PWWIR Project is maintaining local environmental and heritage values.
An Environmental Impact Assessment (EIA) was completed for the project, which examined the impact of the project across a range of environmental areas including flora and fauna, heritage, noise, air emissions and stormwater. As part of the EIA a vegetation survey, marine survey, bird survey and targeted flora and fauna surveys have been undertaken to identify important and / or threatened species.
Referral documentation was submitted to the Department of Sustainability, Environment, Water, Population and Communities (SEWPaC) for consideration of potential environmental impacts of the project under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). SEWPaC determined that the project would not have any significant impacts on the matters protected under the EPBC Act 1999.
The PWEA forms part of the Point Wilson Defence Natural Area which is listed on the Commonwealth Heritage List for its natural heritage values. A cultural heritage assessment, which included the involvement of the Registered Aboriginal Party, has been undertaken as part of environmental assessments. Areas of cultural sensitivity have been identified and would be avoided during the PWWIR works.
Non-indigenous heritage assessments have also been completed. The identified historic heritage values of the jetty and wharf would be retained through the ongoing use of the infrastructure for its original purpose and by retaining portions of the original fabric, such as the end section of the wharf and jetty pylons.
A Construction Environmental Management Plan will ensure all environmental and heritage impacts are mitigated throughout the project. Project works will also be undertaken in accordance with the conditions set in the referral decision from SEWPaC.
