The Wollongong Gasworks site formerly operated as a gasworks site between 1883 and 1977.
Jemena Gas Networks (NSW) Ltd, a subsidiary of Jemena Limited acquired the site following the acquisition of assets from the Australian Gas Lighting (AGL) company in 2007. Following the acquisition Jemena became responsible for the management and oversight of its legacy contaminated sites.
There have been numerous investigations of the site between 1997 and 2017. The soil and groundwater at the site have been contaminated by the historical waste produced by the gasworks during its operation.
The gas manufacturing infrastructure located on the site included a retort house, boiler, exhaust house, washers and purifiers, coal storage areas, tar wells, gas holders and a drum filling area. The aboveground site infrastructure was demolished in the 1980s and a section of the site (Lot 2412) was remediated by excavation of hydrocarbon impacted soil in 2005.
The site is currently being monitored on the Contaminated Site Risk Register and is classified as High. The NSW Environment Protection Authority (EPA) issued a Section 77 Notice requesting information on the current status of the site. A detailed site investigation report was submitted to the EPA on 31 January 2017 in response to this notice which addresses the data gaps and concerns highlighted by the NSW EPA accredited Auditor for the site. The EPA have indicated that they will reserve their decision to declare the site contaminated under the CLM Act 1997, based on the understanding that Jemena will continue to progress the remediation in a timely manner with ongoing regular communication with the EPA.
Since the 2005 remediation works, a number of investigations have been conducted at the site. A NSW EPA accredited Contaminated Sites Auditor has been engaged to provide technical input and oversight for the project.
Following the completion of last phase of investigations at Wollongong, Environmental Earth Sciences was engaged to undertake a Data Gap Analysis (DGA) and Remediation Options Assessment (ROA). The recommendations from the ROA will be used to develop a Remediation Action Plan (RAP). This RAP will be reviewed by the NSW EPA accredited Site Auditor and the NSW EPA.
Due to the complexities of the project and to ensure minimal disruption to the community, Jemena continues to engage extensively with specialist consultants, contractors and government departments. This will ensure the project is appropriately scoped, planned and implemented.
Information for residents
Consultation with the community and stakeholders continues as we proceed towards further investigation. Jemena is also working towards obtaining the necessary statutory approvals required before commencement of any works.
Jemena has conducted some environmental investigation work near the former gasworks site. Environmental investigations are required to understand the nature and extent of contamination at the site and develop an action plan for the site.
