Environmental approvals and risk assessment for expansion of the Granny Smith Gold Mine gas power station to increase capacity to 55.13MW.
Gold Fields
Laverton, Western Australia
CDM Smith delivered environmental approvals support for the proposed 15MW expansion of the Granny Smith Gold Mine gas power station. The team conducted a comprehensive environmental risk assessment, recommended the approvals pathway, and prepared key documentation — including the Mining Proposal and Mine Closure Plan — in accordance with DEMIRS 2020 guidance.
CDM Smith assessed all potential environmental and regulatory risks associated with the power station expansion, ensuring compliance with relevant legislation and minimizing delays in the approvals process.
The team provided a detailed memo outlining the optimal environmental approvals pathway, identifying the need for Works Approval and preparation of Mining Proposal and Mine Closure Plan under the DEMIRS 2020 guidelines.

The Mining Proposal and Mine Closure Plan incorporated detailed risk assessments and mitigation measures, aligning with the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) 2020 guidance for compliance and best practice.
By ensuring all approvals and risk management processes were in place, CDM Smith enabled Gold Fields to responsibly expand its power generation capacity without additional environmental disturbance.
Gold Fields’ Granny Smith Gold Mine (GSM) proposed a 15MW expansion of its existing gas power station, increasing total capacity from 40MW to 55.13MW with the addition of 10 new gas generators. As the facility exceeded 20MW, it was classified as a prescribed premises under the Environmental Protection Regulations 1987. CDM Smith was engaged to conduct a comprehensive environmental risk assessment and define the required approvals pathway. The team reviewed environmental risks, assessed potential delays, and prepared a detailed memo recommending approvals including a Works Approval, Mining Proposal (MP), and Mine Closure Plan (MCP). Both documents were developed in accordance with DEMIRS 2020 guidelines, incorporating environmental risk assessment and mitigation measures to ensure responsible and compliant project delivery.
