As a Critical State Significant Infrastructure (CSSI) project, HumeLink is following a comprehensive Commonwealth and State environmental assessment process. This acknowledges that CSSI projects are large and complex, and can have major economic, environmental, and social impacts.

As part of the planning approval process, HumeLink was required to prepare an Environmental Impact Statement (EIS). An EIS identifies and assesses the potential environmental, economic and social impacts of the project to help government agencies, relevant authorities, community and stakeholders to make an informed decision or provide an informed submission on the merits of the project. ​​ 

The EIS is firstly assessed by the NSW Government and then sent to the Commonwealth Government for assessment 

Public exhibition

On August 30, 2023 the EIS was lodged with the NSW Department of Planning and Environment (DPE) and placed on public exhibition. The EIS public exhibition commenced 30 August 2023 and concluded Tuesday 10 October 2023.

During the EIS public exhibition, the community had the opportunity to read the EIS document, seek clarification and provide feedback directly to the DPE in a formal submission.

The EIS and specialist studies were available online via the DPE Major Projects Planning Portal. Printed copies were also available during the exhibition period at select community libraries across the project footprint and DPE offices.

Throughout the EIS public exhibition, a digital EIS was made available which is an interactive platform to present the key outcomes of the EIS and support a better understanding of the project. As the public exhibition has concluded, our digital EIS has now closed. It was made available for four months from the first date of public exhibition, 30 August 2023.

During the exhibition the HumeLink project team held 22 community information sessions across the project footprint. We also visited landowners with our Remote Access Community Hub (RACH), held additional sessions for Community Consultative Group members, and promoted our information sessions extensively across local media, in our newsletters and updates.

Project determination

The HumeLink EIS public exhibition has now concluded. The submissions received during public exhibition are used to guide the final determination, as well as any approval conditions for the project. All submissions received will be posted on the DPE's website and shared with Transgrid. We will review and respond to submissions in a Submissions Report which will be publicly available on the Major Project Planning Portal for public viewing.

Following this, a final assessment of the EIS including feedback will be undertaken by the DPE and a determination (decision) made. If approval is granted, a report outlining Conditions of Approval for the next stage of the project will be given by the Minister.
