Penalty Notice issued to Centennial Mandalong Pty Limited (SSD-5144) Central Coast LGA
On 18 March 2022, the Department issued a $15,000 Penalty Notice to Centennial Mandalong Pty Limited (Centennial) for failure to comply with operation noise criteria at their Mandalong Coal Mine. Operation noise criteria were exceeded at two attended noise monitoring locations on 6 December 2021. The exceedances of criteria were determined to be the result of ventilation fans operating on the Mandalong South Surface Site (MSSS). Centennial are actively working on engineering controls to reduce any ongoing impacts and to ensure that noise levels remain compliant.

The Mine supports the local community in many ways, through community sponsorship, employment of approx 400 people (including contractors) and supportin local businesses. Recently Mandalong sponsered my NSW RFS Brigade for new equipment.
If the mine was to close, I (and others) would likely be forced to relocate to another coal mining area given the current economic climate which would have a large impact on the community given the money spent in the local community.
The company and mine has a good history of being environmentally sustainable and this high standard should continue.
I support the extension of Mandalong Mine

Mandalong Mine contributes millions of dollars each year to the local community from wages paid to workers, and the state of NSW also benefits from royalty payments. Mandalong Mine and its workers contribute greatly to local charities and sporting clubs, such as the Westpac Helicopter and Movember just to name a few.
If the extension were to be rejected, then hundreds of workers would be laid off, impacting families and communities from Lake Macquarie, Newcastle and the Hunter Valley.
I urge you to support this project for the benefit of the Hunter Valley and NSW.

Mandalong has an excellent environment program and does not impact heavily on the environment or community; the southern extension will keep the same high standards of environmental impact. Subsidence is highly monitored and minimised by the mines design, dust is low due to the underground nature of the mine and noise is controlled by restrictions on machine movements.
Over all I personally think the mine, and the extension, is good for the community and surrounding area, as well as the state due to royalties, while maintaining a small environmental footprint.

It has a very low environmental impact on surrounding areas.
It also employs local youth as apprentices which is very important if we are to have trades people in the future.

I am married with 5 children, with their currant education ranging from Primary school to University of which my wife and I work to enable our children this education, my taxes paid through my employment at Mandalong enable our state/ federal governments the ability to supply teachers, police, ambulance,fire brigades and other essential services to NSW
My children also participate in swimming, nippers, athletics, netball ,golf and oz tag all of which provides for a healthy and active lifestyle,this would be difficult to afford without my employment at Mandalong Mine.
The Mandalong South extension will see the future of Mandalong Mine increase through to 2035, this will enable me the opportunity to raise my children in our existing area, continue to attend there present schools, attend our local swimming clubs, continue to be members of local teams/clubs including voluntary patrols for our local surf club and the monies that I earn will continue to be injected back into the local community.

Centennial Mandalong has been operating for some years now with minimal to no environmental impact or damage to the area and remain committed to continue this into the future. Mandalong is also a valuable supplier of coal to our local power stations which may have to source coal from other suppliers if this extension is not granted.
In closing, Centennial Mandalong not only provides valuable employment for the local community, supplies coal to our local power stations and is committed to the environment it also supports local community sporting teams and events and is an asset to many lake Macquarie, central coast and hunter communities. I fully support the application and look forward to many more years of employment at Centennial Mandalong.

Without the approval of the Extension, the mine will close in 2018, leaving aproximately 400 direct employees out of work & countless businesses & support industries with reduced incomes. Currently all the employees of Mandalong Mine will be spending their incomes in the greater community, which, along with all the employees of support businesses, will contribute greatly to the economy of the greater community around the mine.
Mandalong Mine, like all mines in NSW, pay royalties & the employees pay their taxes. Without approval for the Southern Extension, these monies will be gone from the State Treasury which will impact heavily on the ability to maintain roads, build hospitals, provide for schools etc.
On an environmental front, Mandalong has always been an extremely dilligent member of the community with an excellent record of environmental management. The Southern Extension Project will only continue to maintain the already high standards that are exhibited by the current Mine.
In conclusion, I would like to see this Extension Project approved as it will continue to bring positive inputs to the local community, the State & Australia.

During the almost 3 decades that I have worked in the coal industry, I have witnessed a lot of change in the key areas of safety, environment and legislative compliance. These have all been positive changes.
No longer can we accept that employees are injured at work as they are employed in a dangerous industry. Everyone at Mandalong Mine is focused on the safe production of coal and are proactive with workplace safety.
In part of my role as the projects surveyor, I work closely with the environmental team, being involved with the constant improvements to the mine's surface water management and noise compliance. The mine has further tried to reduce it's environmental foot print, by constructing a trial VAM RAB plant, that converts the mine fan emissions of low concentrations of methane into less harmful carbon dioxide. Also Mandalong Mine has tried to reduce the volume of inseam methane gas that is vented to atmosphere through the mine ventilation fans, by drilling gas drainage boreholes within the coal seam. This methane is currently being burnt off at a purpose built surface facility, with plans to install a power generation unit in the near future.
I am proud of my role as project manager for exploration drilling at Mandalong Mine. The mine is undertaking a drilling program to prove the location of an igneous sill which will define the limit of the minable coal resource and will continue in 2014. The Department of Planning recently conducted a 3 yearly audit of our mines operation. The audit found no non compliances in relation to exploration drilling. The mine spent 1.2m last financial year conducting this drilling program which directly employed 4 drillers and countless subcontractors.
My main role at Mandalong Mine is the measurement of mine subsidence. The mine uses an innovative mine design that minimises the effects of mining on the surface. Voussoir Beam Theory is based on civil engineering design and was adapted to the geotechnical design of the longwall blocks used at Mandalong Mine. The mine extracts up to 4.8m of coal with little of this mining void transferred to the surface topography as the Munmorah Conglomerate unit that lies approximately 70m above the coal seam, spans across the pillars either side of the longwall void. This conglomerate "bends" rather than breaks and so the mine subsidence has no relationship to the extracted void height, rather it is a function of the beam sag, maingate Pillar loading, and floor compression. Contrary to popular belief, subsidence doesn't cause damage to surface structures, it is the tilts and stains that are associated with this movement that does. The maingate pillars absorb half of the total vertical movement due to loading from the extracted void. This reduces the differential subsidence between subsequent longwall blocks, which in turn significantly reduces the tilts and strains on the surface, minimising the effects of mining on surface structures.
I live only 20 minutes from the mine site. My wife also works at the local hospital as a registered nurse. I have lived in this community for almost 50 years and am proud to be a third generation coal miner, both of my grandfathers were coal miners, and my father was also a coal miner. Both my wife and myself spend our wages locally which benefits the whole community.
I feel the continuation of Mandalong Mine into the new exploration area, will not only guarantee the employment of its existing workers but also the many local support contractors who rely on the mine for work. The whole state will also benefit from the continuation of Mandalong Ming through payrole taxes, employees personal taxes and mining royalties.
I hope that the NSW government will approve the granting of a Coal Mining Lease over the Mandalong South Exploration Area, for the benefit of all of the people who live in the community where it operates.
