Under the Environmental Planning & Assessment Act 1979 (EP&A Act), some infrastructure projects can be classified as State significant infrastructure (SSI) if they are important to the State for economic, environmental or social reasons.
Further, some SSI projects can be classified as Critical State Significant Infrastructure (CSSI) if the Minister for Planning determines they are essential to the State.
Both SSI and CSSI projects are assessed under Division 5.2 of the EP&A Act and require the approval of the Minister for Planning before they may be proceed.
The Department of Planning co-ordinates the detailed assessment of the merits of these projects against the triple-bottom-line.
Community participation is an essential part of this process, and all SSI applications are exhibited for at least 28 days.
