Main Content

Mannering is a small underground thermal coalmine located at Mannering Park in southern Lake Macquarie. Centennial acquired Mannering, which was on ‘care & maintenance’, when it purchased the NSW Government’s state-owned mines (Powercoal) in 2002.  Mannering was reopened in 2004 to supply coal via a dedicated overland conveyor direct to Vales Point Power Station.

Centennial placed Mannering on ‘care & maintenance’ in January 2013.  In October 2013, Centennial entered into a production sharing arrangement with LDO's Chain Valley Colliery.  Accordingly, LDO has assumed responsibility for all site matters for the duration of the Mining Cooperation Deed.

Pollution Incident Response Management Plan

The Pollution Incident Response Management Plan has been developed to satisfy the requirements of the Protection of the Environment Legislation Amendment Act 2011 (POELA Act) which requires the preparation, implementation and publication of a Pollution Incident Response Management Plan.
The objectives of these plans are to provide guidelines and procedures for the effective control and reporting of pollution incidents to all relevant stakeholders.
Whilst personal contact details for the following document are available in the controlled on-site Pollution Incident Response Management Plan, they do not appear in this public document under provision of the Privacy and Personal Information Protection Act 1998.

Subsidence Management Plans

Subsidence Management Plans (SMPs) are prepared by mining lease holders to consider the potential impacts of underground mining and identify measures to manage such impacts. SMPs may contain requirements for the avoidance of damage to particularly significant features, the mitigation of damage, or rehabilitation of subsidence related impacts.
