Yarraville Remediation Project
Orica is conducting a remediation project at a site in Yarraville, Melbourne.
This webpage provides information on the project, access to key documents and a project schedule that will be updated as planning and the project progresses.
The remediation project will address on-site nitrogenated hydrocarbon and chlorinated hydrocarbon (CHC) contamination, associated with past manufacturing operations. It will include two distinct activities:
- Excavation of contaminated soil for transport and thermal treatment at a licensed off-site facility; and
- Remediation of soil and shallow groundwater, involving a technology called “in-situ thermal desorption” (ISTD), where electrical heaters are drilled into the ground to a depth of up to 7 m. The soil is heated to approximately 100°C and the volatile hydrocarbons are extracted and treated in a small on-site treatment plant.
The project is being conducted in accordance with Environment Protection Authority Victoria (EPA) requirements under Clean Up Notice's issued in December 2016 and June 2018.
More information is included in the Fact Sheet below.
The current project schedule is shown below. This is subject to change and will be updated as the project progresses.

Orica has engaged with its neighbours, the nearby community and other stakeholders regarding the Yarraville Remediation project through meetings, face to face discussions with neighbours, letters, emails and phone calls.
Consultation will be maintained with interested parties throughout the project to ensure questions can be addressed and feedback responded to in a timely manner.
