An environmental audit is a documented evaluation of an action and its environmental impact (including an evaluation of management practices, systems and plant) for any of the following purposes:
(a) to provide information to the persons managing the action on compliance with legal requirements, codes of practice and relevant policies relating to the protection of the environment;
(b) to enable persons to determine whether the way the action is carried out can be improved in order to protect the environment;
(c) to assess the nature, type, intensity, magnitude and extent of environmental impacts;
(d) to assess whether environmental impacts have been, or are being, appropriately managed;
(e) to assess whether measures to minimise or remediate environmental harm or to rehabilitate the environment have been taken or have been effective;
(f) to assess the effectiveness of the safeguards or standards for the protection of the environment applied or adopted in relation to the action;
(g) to obtain improved information as to the effectiveness and accuracy of the risk management processes and systems used to identify environmental impacts during the environmental impact assessment process;
(h) to assess the accuracy of forecasts of the environmental impacts of the action.
