We have been undertaking feasibility assessments on the land and waterways commencing technical and environmental studies for the Environmental Impact Statement in August 2023 with the release of the NSW Government’s Secretary’s Environmental Assessment Requirements (SEARs).

The NSW Government recently updated the SEARs in line with the project’s CSSI designation.

Scientists, engineers and independent experts have been undertaking technical work to develop the concept design and identify the potential impacts of the project and mitigation measures for biodiversity, aquatic ecology, Aboriginal heritage, social impact, water, climate effects and more.

The studies span day and night, across seasons and extend to understanding the movements of transitory and migratory animal species with insights guiding the project team to provide special considerations in design and construction where necessary.

While technical and environmental studies are underway, community engagement is ongoing through Project HQ, popup engagements at community events; regular Community Consultative Committee meetings; briefings and presentations to Lithgow City Council; one on one discussion with near neighbours and responses to the community hotline and inbox.
