Hazelland Pty Ltd (Hazelland) owns a former landfill site at Lot 20 Adelaide Street in Hazelmere (Lot 20), which has been classified as contaminated - remediation required under the Contaminated Sites Act 2003 (CS Act) since 2010. In accordance with its classification, Lot 20 is required to be remediated. There are many different methods of remediation, which can include containing and restricting access (for example, capping) to the substance causing the contamination.
On behalf of Hazelland, Wasterock Pty Ltd (Wasterock) proposed to remediate the site by excavating the landfill material, screening and sorting it, before covering the landfill with an engineered barrier layer and capping it. Following remediation, the site was proposed for commercial/industrial development.
The proposal was referred to the Environmental Protection Authority (EPA) in 2013. In 2015, the EPA determined that although the proposal raised a number of environmental issues, these issues could be adequately regulated and managed through the CS Act and the works approval and licensing process of the Environmental Protection Act 1986 (EP Act).
The Minister for Environment received three appeals against the decision of the EPA not to assess the proposal, which were investigated by the Appeals Convenor.
In May 2017, Wasterock advised the Appeals Convenor that the proposal that was the subject of appeal would not be implemented, and that it had withdrawn its applications for a works approval and licence under Part V of the EP Act. Wasterock also advised that a new proposal to remediate the site would be implemented without triggering the requirement for a works approval or licence under the EP Act.
In July 2017, the Minister wrote to the EPA and requested it consider whether or not the proposal should be subject to a formal impact assessment. The Minister also advised the appellants that he would place the appeals on the original proposal in abeyance until the status of the new proposal was clarified.
Hazard Abatement Notice - Contaminated Sites Act 2003
On 9 December 2016, the Department of Water and Environmental Regulation (DWER) issued a Hazard Abatement Notice (HAN) to Hazelland.
This notice required Hazelland to construct firebreaks, build and maintain secure permanent fencing, gates and warning signs at the site.
On 6 February 2017, DWER amended the HAN to provide Hazelland with additional time to complete the fencing, due to the need for earthworks to be carried out and access to resources to undertake those works.
Fencing of most of the site was completed by 7 February 2017—as required by the amended HAN. Fencing of the remaining section, along the site’s boundary with Lot 501 (to the south-east), was completed in late 2019.
Firebreaks have also been installed by the site owner, in consultation with the City of Swan.

New proposal to remediate and develop the site
The Chairman of the Environmental Protection Authority (EPA) has determined to assess a proposal from Wasterock and Hazelland to remediate the historical landfill at Lot 20 Adelaide Street Hazelmere for future commercial use at level of assessment of Public Environmental Review, the highest level of assessment.
The new proposal would involve re-contouring the existing site and capping it with clean fill.
The EPA decision said detailed assessment was required to determine the extent of the proposal’s direct and indirect impacts and how environmental issues would be managed. The EPA’s assessment would include opportunities for public participation, including a two week public review period for the environmental scoping document and a four week public review period for the environmental review document.
The EPA’s assessment is currently on hold while the proponent prepares information to support the assessment process.
In February 2019 DWER again amended the Hazard Abatement Notice to require Hazelland to seek DWER’s prior approval before carrying out soil-disturbing works on the site. The amendment is intended to apply while the EPA considers the new remediation proposal.
In addition, DWER has advised Hazelland in writing that, under the Contaminated Sites Act 2003, the company will require a new Remedial Action Plan (RAP) to evaluate remedial options, specify how the remediation will be carried out (from start to finish) and how it will be validated. The RAP is also to document the measures that will be used to protect public and worker health and safety, the environment and aesthetic considerations.
Hazelland will also need to engage an accredited contaminated sites auditor to review the RAP, before it is submitted to DWER and the Department of Health.
