Local and regional economic benefits

  • Expected ongoing permanent employment for nearly 400 people for 13 years
  • Approximately 175 new construction jobs over next two years
  • Continued financial and in-kind support for local community groups and activities

SIMEC Mining has lodged an amended plan for the proposed southern continuation of the Tahmoor high grade coking coal mine which can deliver significant reductions in key environmental impacts while preserving important local area and regional economic benefits and community support.

The proposed extension area for Tahmoor mine has been designated as a potential coal mining site since the Tahmoor mine licence was first approved over 40 years ago.

The revised plan is the Company’s response to government department and community feedback on the project’s Environmental Impact Statement (EIS) exhibited last year. It will now be considered by planning authorities before being assessed by the Independent Planning Commission of NSW in the coming months. During this time, the company will engage extensively with the local community.

Matt Reed, Executive Managing Director at SIMEC Mining, said: “While the great majority of community submissions on our original plan for the mine extension were supportive and no Government department objected to the proposal, we have worked hard to address some important and constructive requests and submissions that have been made by both government and the public.”

“The revised plan contains significant environmental impact improvements while also preserving, if not improving, important local area economic and community support benefits.

“We believe our plan for continuation of the mine’s operations for a further 13 years can make an important contribution as the Shire and the community work to overcome the impacts of the recent bushfires.

“If approved, the mine extension will be a major source of secure employment and related economic stimulus valued at around $160 million for the local shire over the 13 years of operations,” Mr Reed said.

The first mining activity is expected to commence in 2022 once a detailed Extraction Plan has been approved by the NSW Department of Planning, Industry and Environment (DPIE). The Extraction Plan will detail the process for management of all major aspects of the mining process including areas where some subsidence is likely and any anticipated impacts on existing dwellings or other built structures. During this process, mine management will contact residents living in, or who own properties located above mine activity, to brief them on any potential impacts and the process for monitoring and addressing them.

Mr Reed said, “As with the current Tahmoor operations, we will maintain regular contact with our neighbours and the community regarding the updated plan.”

The extension of mining into Tahmoor South from 2022 will ensure continuity of operations as the Tahmoor North mine plan is completed at that time.
