Kendall Bay is located on the Parramatta River in the City of Canada Bay Local Government Area. It is approximately 10 km from the CBD and sits between the suburbs of Cabarita and Breakfast Point.
Why is Remediation Required?
The proposed remediation site is located in Kendall Bay, which is off the Parramatta River, adjacent to the Breakfast Point Residential development. The contamination of the sediments in Kendall Bay was the result of historical industrial discharges from the adjacent former AGL Mortlake Gasworks site (currently the Breakfast Point development).
With the completion of remediation at Breakfast Point, the NSW Environment Protection Authority (EPA) focused on remediating contaminated sediments within areas of Kendall Bay. AGL signed a Voluntary Remediation Agreement (VRA) with the NSW EPA in 2005. The VRA committed AGL to further investigations with the view to remediate the sediments within the bay, where necessary. Jemena inherited AGL’s VRA obligations in late 2006 when the AGL Group was split up. Following these investigations, it was confirmed by the EPA that the remediation of parts of Kendall Bay is required to address health and environmental risks posed by contamination. Jemena’s Voluntary Management Proposal (VMP) for the remediation phase of the project was accepted by the EPA in 2017. The remediation process is regulated by the NSW EPA.
Due to the complexities of the project and to ensure minimal disruption to the community, Jemena has engaged extensively with specialist consultants, remediation contractors, government and community stakeholders. . This will ensure the remediation project is appropriately scoped, planned and implemented.
An important component of the project planning has been consultation with the community. Jemena continues to engage with the local community as we proceed towards the start of the remediation works, now that the necessary statutory approval has been received from the Department of Planning, Industry & Environment (DPI&E).

Jemena submitted a development application (DA) to the Department of Planning, Industry and Environment for the full scale Remediation Project. The DA including the EIS for the proposal was on public exhibition from 3 October 2018 until 31 October 2018.
The EIS included a range of specialist studies to assess the environmental and social acceptability of the proposed remediation work.
The EIS has been assessed by DP&E with input from the other relevant agencies and the Project received Consent from the NSW Minister for Planning, on 31st May 2019.
Jemena has engaged a remediation contractor, Ventia, to carry out the remediation work, following a successful trial of the proposed in-situ stabilisation remediation method undertaken in August/September 2018.
The Project team mobilised to the Staging Site at Tennyson Road, Mortlake in September 2019 in preparation for the commencement of the full scale remediation works. Work to install the Environmental controls is progressing well; including Sheet pile walls to the Northern and Southern areas. It is estimated that the Insitu-Stabilisation (ISS) works will commence in February 2020.
Sediment remediation trial works in Kendall Bay
Jemena’s remediation contractor Ventia completed a sediment remediation trial in the southern portion of Kendall Bay in August/September 2018. The trial involved a limited field trial of the remediation method (in-situ stabilisation) and further collection of sediment samples for laboratory testing and analysis. The plant and equipment deployed operated successfully and validation samples collected showed quality mixing of treatment material within the sediment. The Site Auditor and EPA have agreed the trial was successful and support proceeding to full scale remediation works
Full scale remediation works are expected to take approximately 15 months (weather permitting). The EIS estimated a project timeframe of between 16-28 months, however Jemena recognise the importance of completing the remediation work as efficiently as possible to minimise impacts on the local community.
Information for residents
Community information sessions were held prior to works commencing including during the EIS exhibition period with key members of the Project team, including technical and environmental specialists available to explain the details of the Project and assist with questions regarding public submissions.
Jemena continue to meet with the Community Liaison Group (CLG) to provide regular updates on progress, environmental monitoring results and to seek feedback on community issues or concerns.
