What is an Environmental Audit?

The environmental audit system for contaminated land, provides a mechanism to assure planning and responsible authorities (e.g. councils), landholders and other stakeholders that a potential contaminated site is suitable for use; this is specifically relevant when a development commences or if a change in land use is proposed.

The majority of Australian states and territories have developed legislation, regulations and guidelines for the management of contaminated sites, in accordance with the Commonwealth framework. This comprises of a requirement to undertake environmental audits on specific projects to meet the standards of the relevant state, territory or council.

Epic Environmental’s experienced auditor and qualified technical support staff can provide independent assessment of sites, to ensure the relevant conditions relating to the project’s approval has been met.


The Department of Environment and Heritage Protection (DEHP), manages the contaminated land auditor system in Queensland, under the ‘Environmental Protection Act 1994’.

A contaminated land auditor, is responsible for reviewing the work of a suitably qualified person, (SQP) by evaluating and certifying site investigation and validation reports and drafting the site management plans that are submitted for a decision on a land contamination matter.

Auditors provide certainty on the regulatory function performed and can assist in streamlining the decision process for land contamination matters. A complex project may benefit from an approved auditor, as they oversee and evaluate the project; certifying it at several stages.

The functions of a contaminated land auditor are performed outside of the statutory decision timeframes—which are only activated once a submission has been made.

Approved auditors for contaminated land, also carry out compliance assessment for development requiring a compliance permit under the Sustainable Planning Act 2009.

New South Wales

The Environment Protection Authority (EPA) under Part 4 of the Contaminated Land Management Act 1997, administers the NSW site auditor scheme.

The site audit statement and site audit report are the outcomes of the audit. The report supports the statement, which comprises of four parts. The site audit statement can be to: determine suitability of a site; or nature and extent of contamination and/or appropriateness of investigation / remediation / management plan and/or determine if land can be made suitable by implementing a remedial action plan and/or management plan.

The site auditor scheme has an important role in supporting decision-making by determining authorities. State Environmental Planning Policy 55 (SEPP55), requires determining authorities to consider the potential for contamination at a site (and adjacent sites) prior to planning decisions being made. This obtains relevance, for instance, where land with a known or suspected history of potentially contaminating industrial or commercial activities is proposed to be redeveloped for a more ‘sensitive’ purpose, such as a residential use; this consideration by authorities requires specific information about any potential contamination.

Engaging an Auditor

An accredited site auditor provides increased certainty to planning authorities, about the nature and extent of contamination and the suitability of a site for a specified use.

Brad May is well suited to complete audits in both Queensland and New South Wales, ensuring requirements are met on time and within the budget.
