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.

Project Overview

The remediation project will address nitrogenated hydrocarbon and chlorinated hydrocarbon (CHC) contamination, associated with past manufacturing operations. It will include two distinct activities: 

  1. Excavation of contaminated soil for transport and thermal treatment at a licensed off-site facility; and 
  2. Remediation of soil and shallow groundwater, involving a technology called “in-situ thermal desorption” (ISTD), where gas fired thermal heaters are drilled into the ground to a depth of up to 8m. The soil is heated to approximately 100°C and the volatile hydrocarbons are extracted and treated in a small on-site treatment plant.

The area proposed for remediation via excavation and one of two ISTD remediation areas have been completed. The final ISTD remediation area is planned to be conducted and completed by the end of 2022. 

The project is being conducted in accordance with Environment Protection Authority Victoria (EPA) requirements under a Clean Up Notice issued in June 2020. 

More information is included in the Fact Sheet below.

* ISTD remediation works are being completed by a specialist contractor from the USA and works were impacted by travel restrictions that were implemented by the Australaian Government, to protect the health of the Australian community from the spread of COVID-19. Works were put on hold between April and October 2020 until exemption to the travel restrictions were granted.

Stakeholder Consultation

Orica has engaged with its neighbours, the nearby community and other stakeholders regarding the Yarraville Remediation project through meetings, face to face discussions, 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.
