Location:
Eastern foreshore of Homebush Bay.
Owner:
NSW Maritime.
Project Manager:
NSW Maritime/Department of Commerce.
Area:
Approximately 11 Hectares.
Value:
Approximately $100M of which $21M is being committed by NSW Maritime.
Project:
- The "Union Carbide" site (also known as the Lednez site) and the Bay area adjoining it have become contaminated with a range of contaminants, including dioxins, due to past industrial use.
- After a NSW Government Commission of Inquiry review of the project, planning consent for the remediation was granted in May 2004.
- NSW Maritime subsequently let a contract to permanently destroy the contaminants. This will allow the land to be put to productive uses as defined in the Rhodes Peninsula Regional Environmental Plan.
- The contractor, Thiess Environmental Services has obtained all necessary operating licence approvals and commenced mobilisationi in May 2005.
- At the same time Meriton let a contract to remediate the former Allied Feeds site.
- When completed by the end of 2009, both the “Union Carbide” site and the Bay area will be considered safe for human occupation and use, at what was regarded as the most contaminated site in the Sydney region.
Recent Project Milestones:
