Site remediation

In December 2022, the EPA entered into an Environment Performance Agreement (the Agreement) with Renewal SA and MAB for the gasworks site. The Agreement requires MAB to engage an EPA-accredited site contamination auditor to complete a site contamination audit. The auditor is overseeing and reviewing the assessment and remediation undertaken at the site to confirm that the remediation undertaken has made the land suitable for the proposed use.

The Agreement allows the EPA to maintain regulatory involvement in the assessment and remediation of site contamination at the site. It also requires MAB to submit a number of deliverables to the EPA, including the following documents:

  • Revised site specific risk assessment
  • Remediation options assessment
  • Site remediation plan
  • Community engagement plan
  • Interim audit advice
  • Quarterly progress reports.


The deliverable reports recorded in the EPA Public Register are available in the Reports library. Any additional reports will be added when they become available in the Public Register. Please contact the EPA Public Register administrator for a copy of the Agreement.

The deliverables under the Agreement are intended to achieve the following:

  • Confirm the nature and extent of site contamination
  • Identify and assess any potential risks to human health and the environment
  • Develop and execute a site remediation plan
  • Validate the suitability of the site for the proposed land use
  • Address any residual site contamination through the development of a site management plan as necessary
  • Provide sufficient information to enable the auditor to prepare a site contamination audit report.


In August 2023, the auditor prepared interim audit advice which endorsed the remediation proposed in a site remediation plan. Following the EPA’s acceptance of the interim audit advice, remediation commenced at the site. Site remediation is being undertaken by MAB’s remediation contractor, Enviropacific.

As of November 2024, the majority of the remediation described in the site remediation plan has been completed, with some remaining remediation to be undertaken.
