||If an Environmental Planning Instrument provides that a Development Consent is not required for a particular type of development, and the development requires some authorisation by a public authority in order to be carried out, then the activity should be assessed in accordance with Part 5 of the Environmental Planning and Assessment Act 1979 (NSW). A Part 5 Environmental Assessment requires a determining authority to take into account the environment to the 'fullest extent possible'. This includes where the proponent of the works is a public authority. An example is a ports authority carrying out certain low impact works which do not require Development Consent. The relevant Minister or public authority for these types of proposals must still have regard to the environmental impact of the proposal. If any proposal is likely to have a significant effect on the environment, an Environmental Impact Statement must be prepared and the public must be given an opportunity to make submissions prior to the activity taking place.
