Main Content

Myuna is an underground coal mine located in Wangi Wangi, Lake Macquarie in the Newcastle Coalfields, approximately 25 kilometres south-west of Newcastle.

In January 2012, Myuna received Project Approval for the continuation of mining until 31 December 2032.

This approval extends mining and coal handling at Myuna within the lease area and proposes to:

  • mine using bord and pillar mining methods in the Wallarah, Great Northern, and Fassifern seams in CCL762 and ML1370;
  • produce, handle and distribute to Eraring Power Station, up to 2 million tonnes per annum (Mtpa) using existing infrastructure;
  • continue the use of ancillary infrastructure and service;
  • upgrade the water management system; and
  • rehabilitate the surface facilities within 5 years of completion of mining.

Myuna had an excellent year in 2011 achieving new production records. Myuna places a large amount of emphasis on safety and environmental improvements. At the 2011 Centennial Coal Health Safety Environment and Community Innovation Conference Myuna was awarded both the Judges and Peoples First Place Award.

The mine prides itself in maintaining strong partnerships with local community groups in Wangi Wangi. An example of our ongoing sponsorships include:

  • Wangi Lions Club and the Dobell Arts and Craft Festival
  • Wangi RSL Amateur Sailing Club and the Australia Day Regatta
  • Macquarie Scorpions Rugby League Club
  • Rotary Club of Toronto Lake Macquarie Paddlefest
  • Toronto Ladies Golf Club
  • Morisset and Toronto Meals on Wheels

Environmental Protection and Biodiversity Conservation (EPBC)

The Environment Protection and Biodiversity Conservation (EPBC) Act is administered by the Federal Government's Department of Environment which is incorporated into the Department of Sustainability, Environment, Water, Populations and Communities.

The EPBC Act requires any person who proposes to undertake an action that will have, or is likely to have, a significant impact on a matter of national environmental significance to refer that action to the Minister for a decision as to whether assessment and approval is required under the EPBC Act. This decision is referred to as a ‘controlled action’. Where it is deemed a controlled action, the Minister may approve the action and issue conditions of approval

Mining Operations Plan / Rehabilitation Management Plan

Mining operations in NSW are required, as a condition of an authorisation issued under the Mining Act, to conduct mining operations in accordance with a Mining Operations Plan (MOP) that has been approved by NSW Trade and Investment - Division of Resources and Energy.
The MOP describes the manner in which mining, processing, rehabilitation and reporting are to be undertaken with reference to Management Plans and Procedures. The MOP also establishes relationships to other approval and reporting requirements consistent with development consent, leases and licences.

Independent Environmental Audits

Independent Environmental Audits are undertaken regularly as a component of each mining approval. The audit is undertaken by a suitably qualified independent expert. The purpose of the audit is to independently assess the environmental performance of the mine and whether it is complying with the relevant requirements of its project approval, any relevant mining lease and environmental protection licence.
