Statutory guidelines

Section 105 of the Contaminated Land Management Act 1997 (CLM Act) allows the EPA to make or approve guidelines for purposes connected with the objects of the Act. The EPA must consider these guidelines whenever they are relevant.

Other people must also consider the guidelines, namely

  • accredited site auditors when conducting a site audit
  • contaminated land consultants when investigating, remediating, validating and reporting on contaminated sites
  • those responsible for land contamination with a duty to notify the EPA.
