State Significant Development (SSD)

Some types of development are deemed to have State significance due to the size, economic value or potential impacts that a development may have. 


Development that is State significant development (SSD) is identified in the State and Regional Development SEPP.


Types of State significant development

The Government has identified certain types of development that are SSD for examples:

  • new educational establishments, hospitals and correctional centres
  • chemical and other manufacturing
  • mining and extraction operations
  • tourist and recreation facilities
  • some port facilities
  • waste management facilities
  • energy generating facilities.


A development proposal for any of the identified development types is SSD if it:

  • is over a certain size
  • is located in a sensitive environmental area
  • will exceed a specific capital investment


In addition, some development on identified sites can also be SSD. Identified sites include Sydney Olympic Park, Darling Harbour, the Bays Precinct and Barangaroo.


The full list of SSD development types and identified sites can be viewed in Schedules 1 and 2 of the State and Regional Development SEPP.


The Minister for Planning may also ‘call in’ development proposals if a proposal is considered to be of State significance. To find out more about the Ministerial ‘call in’ process, view the Policy Statement and Guideline prepared by the Department.


To find out more about SSD, view the Department’s SSD Fact Sheet and SSD Procedures Policy Statement.


All SSD applications are listed on the Department’s major projects website. The application and all supporting information are available to view online. The website's tracking system identifies what stage a project is up to in the assessment process.


The Department’s assessment report and the application determination (including conditions of consent or reasons for refusal) are also made available to view on that major projects website.


How to lodge a State Significant Development Application

Once you have determined that your proposal is SSD, you can lodge your application online at the major projects website.

The Minister for Planning is the consent authority for SSD applications. SSD applications are assessed by the Department of Planning and Environment. In some cases, the Minister may delegate the decision making function to Department staff.


In addition, if an SSD proposal is not supported by the relevant local council(s), or the Department has received more than 25 public objections, the Department’s recommendation is referred to the Independent Planning Commission (IPC) for determination. View the Minister’s delegations to the IPC.


To find out about applications referred to or determined by the IPC, visit the Independent Planning Commission’s website.

All applications for SSD are publicly exhibited for a minimum 28 days (longer if the exhibition overlaps with the Christmas/New Year period between 20 December and 10 January (inclusive)).


During the public exhibition period for SSD applications, the Department will:

  • notify surrounding residents in writing (council is consulted on the notification area, which will vary depending on the scope of the proposal)
  • place an advertisement in a State wide newspaper
  • place electronic copies of the application and all supporting information on the Department’s major projects website


You can make an online submission about an SSD application during the public exhibition period via the relevant application page on the Department’s major projects website.


You can also send any written submission to the Department by post or email.


You can also view the state significant applications currently on public exhibition.

SSD applications are assessed by the Department of Planning and Environment. The Department considers the following when assessing SSD applications:

  • existing strategic plans and policies (including State, regional and local)
  • feedback and comments from the relevant local council(s)
  • specialised and technical input and advice received from Federal and State Government agencies
  • public submissions received during the exhibition
  • the public interest


The Department’s assessment and recommendation are set out in the Department's Environmental Assessment Report. The recommendation (including either conditions of consent or reasons for refusal) is referred to the Minister, or his delegate for determination.
More information about the assessment processes for SSDs is included in the Department’s Planning Circular.


Examples of Government Agencies Consulted by the Department

  • Environment Protection Authority
  • Office of Environment and Heritage
  • Department of Primary Industries
  • Roads and Maritime Services
  • Transport NSW
  • Department of Education and Communities
  • NSW Health.

An applicant can apply to the Minister for Planning to modify an SSD approval. Requests must be lodged with the Department of Planning and Environment for assessment. The modification request will be appropriately notified / exhibited depending on the scale of the proposed modification and the potential for environmental or social impacts.

The department has prepared sets of standard and model conditions to help the development industry, community, councils and government agencies understand the types of conditions likely to be applied to State significant projects if they are approved.


By providing these sets, the department aims to:


  • provide standard definitions and approaches to issues common to a particular industry,
  • reduce duplication and inconsistency,
  • simplify compliance requirements for approved development.


In developing the conditions, the department has considered feedback from industry, councils and other government agencies.


The conditions are based on sample determinations and cover the following sectors:


Updated conditions for open cut and underground mining are not being published now due to the review of mining policy.
