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 IB105
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.
