Prepare EIS

Assessing the impacts of a project with community engagement

Why is an EIS required?

All development applications (DAs) for state significant development must be accompanied by an environmental impact statement (EIS).

The EIS provides information on the economic, environmental, and social impacts of the project. It helps the community, government agencies and the consent authority make informed submissions or decisions on the project.

Preparing the EIS

The EIS must be prepared in accordance with the Planning Secretary’s environmental assessment requirements (SEARs) and have regard to the State Significant Development Guidelines – Preparing an EIS (Appendix B). 

The preparation of the EIS will typically involve:

  • engaging with the community and public authorities in a manner which is consistent with the Undertaking Engagement Guidelines for State Significant Projects
  • undertaking a technically robust and proportionate assessment of the project, including an analysis of the significant likely impacts of the project in accordance with the SEARs and any relevant government legislation, policies and guidelines
  • refining the design of the project to avoid or minimise impacts
  • integrating the findings of these key activities into a justification and evaluation of the project as a whole.

The EIS must be easy to understand, rigorous and as succinct as possible.

EISs for state significant development applications need to be reviewed by a Registered Environmental Assessment Practitioner (REAP).

Which agencies do I need to engage with?

For industry-specific SEARs, the applicant is responsible for identifying which government agencies they should consult during preparation of the EIS.

These should include agencies that:

  • are relevant to the project
  • you need to, or would otherwise have needed to seek an approval from as per section 4.41 and 4.42 of the EP&A Act

For help identifying which agencies you need to engage with, please contact the Department‘s assessment team.

For project-specific SEARs, the Department will advise which agencies applicants should engage with during preparation of the EIS.

Proponent-led agency engagement

Applicants should directly engage with agencies and councils via Major Projects. Certain agencies that are not available on Major Projects may be contacted directly using the contact details available in the agency directory

Applicants should start consultation with public authorities at least 6 weeks before submitting an EIS. This will allow enough time for feedback to be considered and any additional follow up engagement where necessary.

Prior to contacting an agency, applicants should have:

  • reviewed the SEARs for the project and any other published guidance
  • engaged suitable consultants
  • undertaken due diligence on the site
  • prepared a scope of works for the project, including preliminary documentation (for example, site survey or architectural drawings)
  • identified relevant impacts and the methodology for their assessment
  • formed key questions to guide discussions.

Engagement should be proportionate to the scale and impact of a project. For complex and large-scale development, early engagement may be necessary. All public authority engagement should follow the Undertaking Engagement Guidelines for State Significant Projects


Contacting the department prior to submitting the EIS

A development application isn’t considered lodged until the DA fee is paid. To prevent delays, applicants should submit the payer details form – showing who the invoice should go to – at least 2 weeks before lodging the EIS. 


What happens after the EIS has been completed?

Once the EIS is complete, the applicant must submit the DA in the approved form on the NSW Planning Portal together with the EIS.

The Department will then notify the applicant of the applicable DA fee.

After payment has been received, the application is considered lodged. The EIS will then be put on exhibition, and the community will be invited to have their say.
