Adelaide wharf

Adelaide Refinery

The former Adelaide Refinery at Port Stanvac, located south of Adelaide near Lonsdale, was demolished in early 2014 and a project is underway to remediate the site to a standard suitable for future industrial use.

Mobil is working closely with the South Australian Government, the Environment Protection Authority (EPA), other government departments and agencies as well as the Onkaparinga City Council, to ensure we take every care to minimise the impact of the project on our neighbours and avoid any risk to the surrounding community and the environment.

Mobil is responsible for assessing the environmental condition of the former Adelaide Refinery site and subsequently remediating it to a standard that is suitable for future use. We entered into a Voluntary Site Contamination Assessment Proposal with the EPA under which we have committed to carry out certain environmental assessment and remediation works, primarily focused on the boundaries of the refinery site.

After operations ceased in 2003, Mobil engaged an SA EPA-accredited Site Environmental Auditor to oversee regular environmental assessments of the refinery site and ensure there were no impacts offsite, such as into Gulf St Vincent. We continue to work cooperatively with the Auditor and the EPA on all aspects related to the environmental condition and assessment of the site. Mobil’s environmental consultants conduct six-monthly sampling and analysis of some 150 groundwater wells around the site. They also conduct regular monitoring of the health of the marine environment offshore from the refinery site.

The works currently underway include investigating soil and groundwater conditions to guide the plan to rectify any environmental impacts. This process is regulated by the South Australian EPA.

Sufficiently remediating the site to a standard suitable for future industrial use is likely to take up to 10 years.

Port Stanvac wharf

Removal of the industrial Port Stanvac wharf, which extends 670 metres into the deep waters of Gulf St Vincent at the former Adelaide Refinery site, commenced in 2016. 

Specialist contractor, McConnell Dowell, was selected by Mobil to manage the project which includes the safe removal of industrial infrastructure using specialised equipment.

Following commitment by the State Government in late 2015, Mobil has agreed to fund upgrade works of the 215-metre rock groyne that forms part of the wharf structure so that it can be retained for future use. Upgrade works estimated at over $5 million include adding a walkway along the top of the groyne so that it can be safely accessed once remediation has been completed and the foreshore area is reopened to the public. 

While site remediation at the Adelaide Refinery is expected to take up to ten years, Mobil will work with the South Australian Government to prioritise remediation works along the foreshore so it can be safely opened to the public for recreational purposes such as fishing and diving by around 2020 (subject to approval by the South Australian Environment Protection Authority).

The refinery site and area surrounding the wharf is still an industrial work zone, and to ensure public safety, access is necessarily restricted, as outlined in the exclusion zone notice. 

These restrictions will remain in place until the remediation works have been completed in several years.
