Contaminated land is any area on a site where hazardous substances, such as chemicals, fuel, metals or waste, are present at levels that pose a risks to human health, the environment or commercial activity.
Contamination can be present in soil, groundwater, surface water and building structures. In Western Australia, contaminated land is often required to be managed or remediated to prevent harm.
Common sources of contamination include industrial activity, fuel storage, waste disposal, agriculture, and the historical use of hazardous materials such as asbestos or pesticides.
Importantly, a site does not need to pose an immediate danger to be considered contaminated. Under the Act, contamination also includes sites where hazardous substances are present at levels that may cause future harm if not managed appropriately.
The Act outlines a clear hierarchy to determine who is responsible for cleaning up contaminated sites:
Polluters: Individuals or entities that caused or contributed to the contamination are primarily responsible for remediation.
Landowners or Occupiers Changing Land Use: If a landowner or occupier changes or proposes to change the land’s use, they may assume responsibility for remediation. This is because the new use will change the risks associated with the contamination.
Current Landowners: If the polluter cannot be identified or held accountable, the current landowner may be deemed responsible, particularly if they were aware or should have been aware of the contamination at the time of purchase.
The State: In cases where no responsible party can be identified or held accountable, the State may assume responsibility for remediation.
It is important that owners and developers understand this hierarchy to ensure that they fulfill all obligations required of them. Should they fail to do so, there can be severe legal and financial punishments.
The Contaminated Sites Committee is an independent body established under the Act to make decisions about responsibility for land remediation.
The Committee will determine liability when requested by an interested party or on its own initiative. Decisions made by the Committee are binding and can be appealed to the Supreme Court of Western Australia.
Responsibility for remediation can be transferred under certain conditions
Section 30 Transfers: A person responsible for remediation can transfer responsibility to another party with that party’s written agreement and the written approval of the Minister.
Contractual Agreements: While parties can include indemnity clauses in contracts to allocate financial responsibility, such clauses do not absolve parties of their statutory obligations under the Act.
There are many reasons you may look to transfer responsibility, including the cost of contaminated land remediation. To determine whether you have standing, it is best to contact a contaminated land management expert.
Understanding who is and isn’t liable is essential for all parties involved:
Landowners: Must be aware of their potential liability, especially when changing land use or acquiring property with known or suspected contamination.
Developers: Should conduct thorough due diligence to identify any contamination issues and understand the associated responsibilities and risks.
Buyers and Lessees: Need to be informed of any contamination and the site’s classification to assess potential liabilities and obligations.
A misunderstanding can result in legal repercussions, costly project delays and health risks for the population and environment.
The responsibility to remediate contaminated land in Western Australia is determined by a structured hierarchy under the Contaminated Sites Act 2003.
Stakeholders must be proactive in understanding their responsibilities to protect themselves form legal and professional consequences.
