Classification and Management of Contaminated Soil

​​​​​​​​​​​​Classification and management of contaminated soil (Information Bulletin 105)

Information Bulletin 105 defines the criteria used by the EPA for the classification of contaminated soil that requires treatment and/or off-site disposal, and outlines the management of each classification. It is designed for waste producers, consultants, local government, waste transporters and landfill operators who are responsible for determining whether a potentially contaminated soil is suitable to be disposed of at a landfill; and to assist them in assessing alternative options for contaminated soils management and how to make an application for disposal to the EPA.

​Advisory Note to I​​B105​​​

In 2012 an Advisory Note to IB105 was published to assist in the classification of polycyclic aromatic hydrocarbons (PAHs) and further amendments have been made to IB105 to include per-​ and poly-fluoroalkyl substances (PFAS). Written advice should be sought from the EPA if any doubt exists.
