Modification 11 - Time Extension

I oppose this extension as removing and transporting coal will have obvious environmental impacts, increasing fossil fuel emissions and worsening the effects of climate change. Transporting coal by truck through the Blur Mountains is detrimental to the environment and eco-tourism. Mining has already caused extensive damage to stone pagodas and hanging swamps in the Gardens of Stone and this mining extension threatens to continue that environmental degradation.

I am writing in support of Mod 11, which seeks an extension of time for the existing coal mining operation. The modification is essential for protecting local jobs, maintaining regional economic stability and supporting NSW’s energy security, while continuing to operate with strong environmental performance and full regulatory compliance.

Employment and Economic Benefits
Mod 11 secures approximately 300–400 direct jobs and supports more than 580 additional roles across transport, contracting, maintenance and local services. Coal mining is the largest employment sector in the Lithgow LGA and contributes around $241 million each year to the regional economy. Approval prevents a sudden economic shock that would affect families, businesses and community organisations.

Independent analysis shows Mod 11 delivers substantial net social benefits—$149 million for NSW and $212 million nationally. The operation also provides significant royalties, payroll tax and council rates that help fund essential public services and infrastructure.

Energy Security and Community Stability
The mine supplies coal to Mt Piper Power Station, a key source of reliable baseload electricity during NSW’s transition to renewable energy. Maintaining this supply is critical for grid stability and affordability.

Local consultation shows strong community support for the continuation of the mine, recognising its long history, stable operations and central role in sustaining employment. Without approval, the region would face immediate job losses, reduced household income and avoidable social disruption.

Environmental Performance
Comprehensive assessments confirm Mod 11 results in no significant environmental impacts. The modification introduces no new land disturbance, no expansion of the mine footprint and no additional biodiversity impacts.

Noise modelling shows no increase in community noise levels. Traffic assessments confirm all intersections will continue to operate at good Levels of Service through 2031. Monitoring demonstrates no impacts on sensitive groundwater systems or Temperate Highland Peat Swamps on Sandstone.

Greenhouse gas emissions remain comparatively low and are managed under established plans. Existing noise, water, traffic, GHG and rehabilitation management frameworks remain effective and will continue to be updated as needed.

Conclusion
Mod 11 protects hundreds of local jobs, supports the regional economy, maintains essential energy supply and continues to operate with strong environmental safeguards. It avoids unnecessary social and economic disruption and clearly serves the public interest.

For these reasons, I strongly support approval of Mod 11.

This proposal seeks to extend operations for another five years. At a time when we urgently need to reduce reliance on coal, approving extended coal extraction is the wrong direction. In the past few years we have experienced catastrophic effects of climate change including bushfire, drought and flooding.
Clarence Colliery is mining under million-year-old pagoda formations and ancient hanging swamps. Once these landforms are affected by subsidence, there is no repair. This is particularly critical in terms of the swamps as they are an essential part of the water cycle, filtering and storing water that are essential to both human and more-than-human ecosystems.

If this proposal is to go ahead I strongly reject the continued approval of 300,000 tonnes of coal by truck. As someone who uses Blue Mountains roads, there is no justification for extending years of heavy truck movements through the Blue Mountains and Sydney. Rail is available and its use should be mandatory. It is dangerous and threatening to have such heavy vehicle use of our roads. We are also dealing with constant noise, traffic, and diesel pollution. The highway rund directly through the heart of our villages.
Most Clarence coal is exported. If extraction continues, it should supply Mount Piper Power Station to avoid pressure for new coal from more damaging mines in the region rather than being exported. Make it part of a plan to decarbonize our community and prevent more damaging mining.
Existing rehab commitments are outdated and inadequate. Any extension must impose modern, enforceable rehabilitation standards. The legacy of mining on the edge of the World Heritage National Park continues to pollute waterways and affect the biological systems that generate diversity
This includes disused coal waste heaps of this mine. They must be rehabilitated immediately to prevent fine sediments washing into the Wollangambe River, a listed wild river. I have had the good fortune of canyoning many times on this river. It is SO BEAUTIFUL. Anything that threatens this is not worth allowing.
Put nature first.
Sincerely,
Sarah Daniel.

I fully support this project. Mod 11 is vital to saving jobs in the lithgow region. It supports energy security in NSW, local businesses, and avoids devastating social and community impacts to the lithgow region if these jobs are suddenly lost.
The real community in NSW supports these workers and industry and so should the planning system.
Coal mining and the environment have co-existed in the lithgow region for well over 100 years. This mod is reasonable and should be approved.

I am writing to express my strong opposition to the proposed Modification 11 for the Clarence Colliery (DA504-00-Mod-11), which seeks a five-year extension of its mining consent to 31 December 2031. This submission will demonstrate that approving this modification would be a reckless and irresponsible decision, directly contradicting the NSW Government’s legislated climate targets, jeopardising Sydney’s water supply, and sanctioning further destruction of the unique and sensitive environment of the Gardens of Stone.
The NSW Government has committed to ambitious and legally binding climate change targets. However, the state’s own Net Zero Commission, in its December 2025 ‘Coal Mining Emissions Spotlight Report’, made the unequivocal finding that “Continued extensions or expansions to coal mining in NSW are not consistent with the emissions reduction targets in the Climate Change Act or the Paris Agreement temperature goals it gives effect to."
Approving a five-year extension for the Clarence Colliery would fly in the face of this expert advice. It would lock in significant greenhouse gas emissions for years to come, making it demonstrably harder, if not impossible, for NSW to meet its legislated targets of a 70% emissions reduction by 2035 and net zero by 2050.
Centennial Coal’s track record on water management is appalling, and the risks to the Greater Sydney Water Catchment are too great to ignore. The company’s operations have a history of causing significant and lasting damage to water resources.
Centennial removes more than 20 billion litres of groundwater every year, interrupting groundwater supply and drying out peat swamps.
This massive scale of groundwater extraction has devastating consequences for the sensitive ecosystems of the Gardens of Stone, particularly the Temperate Highland Peat Swamps on Sandstone, a listed Endangered Ecological Community. These swamps are vital for maintaining water quality and flow, and their destruction is irreversible.
Furthermore, Centennial has a demonstrated history of polluting the Wollangambe River, a tributary of the Colo River which flows into the Hawkesbury-Nepean system, a critical part of Sydney’s water supply. The company’s Springvale Water Treatment Plant has failed to operate as a “zero discharge” facility, and has been the subject of legal action and community outrage for its ongoing pollution.
The current proposal for Mod 11 also includes a plan to use coal wash to cap a toxic ash dam at the old Wallerawang Power Station site, located perilously close to Sawyers Swamp Creek. This is an unacceptable risk to an already stressed water system.
The Clarence Colliery is located within the Gardens of Stone State Conservation Area, a region of spectacular natural beauty and immense ecological significance. Centennial Coal’s operations have already caused extensive and well-documented damage to this unique landscape.
A 2024 report by the Lithgow Environment Group documented:
“about 27.8 hectares of damaged swamps or hanging swamps, 10.5 km of dry desiccated creeklines, 3 cliff falls, 2 subsidence cracks, and 3 examples of mine water pollution above Centennial’s Clarence Colliery alone”
This is the legacy of just one of Centennial’s mines. Approving a five-year extension would be to knowingly approve the continuation of this destruction. The proposal to reintroduce longwall mining methods, after years of lower-impact bord-and-pillar mining, would only exacerbate the problems of subsidence, cliff collapse, and damage to pagoda structures.
The economic arguments for extending the life of the Clarence Colliery do not stand up to scrutiny. The global demand for thermal coal is in terminal decline, and propping up this dying industry with new approvals is economically irresponsible. The NSW Government should be investing in a just transition for the Lithgow community, creating sustainable, long-term employment in industries that do not come at the expense of our climate and environment.
The Net Zero Commission report explicitly states that the NSW Government will need to “prioritise its consideration of policies that systematically prepare for the decline of coal extraction and provide for a just and orderly transition for coal-producing communities and impacted regional economies”. Approving this modification would be a step in the opposite direction.
The evidence is clear and overwhelming. The Clarence Colliery Modification 11 proposal is not in the public interest. It is incompatible with our climate targets, it poses an unacceptable risk to our water supply, and it will cause further irreversible damage to a precious and unique natural environment.

The Clarence coal mine extension is unacceptable.
I cannot believe one would even consider the extension with the amount of damage it would do our fragile environment.
We are going into drought and the planet needs the water to provide water to humans, plants n animals.
Waterways are fragile, land and environment is screaming for help, pollution and from trucks and dust adding stress to us all.
Please reconsider - go and have a look for yourself - the environment needs us.
Thank you for your time.

We urgently need to reduce reliance on coal, approving extended coal extraction is the wrong direction for the Gardens of Stone region and for NSW.
If the extension is approved despite community opposition, it must come with these five strict conditions:

1 Link approval to the upgrade of the Lidsdale coal unloader. This critical infrastructure would reduce reliance on the polluting, wet Springvale mine.
2 Reject the continued approval of 300,000 tonnes of coal by truck. There is no justification for extending years of heavy truck movements through the Blue Mountains and Sydney. Rail is available and should be mandatory.
3 Acknowledge the real impacts of truck transport. The claim of “no or negligible” impacts does not reflect the experience of communities dealing with noise, traffic, diesel pollution and road safety risks from over 7000 truck trips every year.I live somewhere that had heavy trucks running past my rural home for a few weeks while the road was being repaired (Deer vale Rd, Fernbrook) and I hate to think about the changes that occured in the bedrock during that time, as I live 50m above the road itself, and items were moving inside my house - vibrating across shelves, some falling to the floor. The changes with heavy trucks are felt every few months, and currently, along the Waterfall Way, as landslides have currently closed a portion of the vital arterial road. heavy truck damage is anything but negligable.
4 Prioritise local use over export. Most Clarence coal is exported. If extraction continues, it should supply Mount Piper Power Station to avoid pressure for new coal from more damaging mines in the region.
5 Strengthen rehabilitation requirements. Existing rehab commitments are outdated and inadequate. Any extension must impose modern, enforceable rehabilitation standards. We know there are places all over our continent subject to rehabilitation after works, and seldom do they meet the requirements of the environment in order for it to function as it did prior to the works.

This is a critical moment. Five more years of coal extraction is not a minor administrative change — it is a significant decision for our environment, our communities and the Gardens of Stone.

This mine extension is a critical path to the future of employment and community to the Lithgow region. Mining has long been a part of Lithgow, supplying employment for many locals and nearby towns.
Approval will ensure the continuation of employment and input into the local community. The mines have been generous also assisting with local hospitals and schools, this approval will help continue this support, something that is desperately needed in these harder times.
Lithgow needs this approval to ensure the town and its younger workforce are catered for in the future.

Clarence supports 300 full time employees including my husband. Clarence also supports many families in our community, supporting up to 580 jobs indirectly on top of the 300 Clarence workers. Clarence also employs multiple apprentices each year providing our young school leavers with a solid start to their working careers. Centennial as a company is a major contributor to our community continually sponsoring sporting teams, community events and provide financial aid for community upgrades. I support Clarance and Centennial because they support my family and community

Submission Opposing Modification 11 – Clarence Colliery Extension
Re: Proposed five-year extension of Clarence Coal Mine operations
To Whom It May Concern,
I write to formally oppose Modification 11 for Clarence Colliery, which seeks to extend coal mining operations for a further five years.
At a time when New South Wales must urgently reduce reliance on coal and accelerate the transition to clean energy, extending coal extraction in the Gardens of Stone region is the wrong direction. This proposal is not a minor administrative amendment. It is a significant decision with lasting consequences for our waterways, landforms, climate, and local communities.
The Gardens of Stone Alliance has rightly called for strong opposition to this extension in its current form. Mining and burning coal continues to drive environmental damage, including impacts on groundwater systems, surface waterways, fragile sandstone landforms and regional air quality. It also undermines NSW’s climate commitments by prolonging fossil fuel dependence.
If the Department determines to approve the extension despite substantial community opposition, then approval must be conditional on the following strict and enforceable requirements:

Approval must be contingent on the upgrade of the Lidsdale coal unloader. This infrastructure is essential to reduce reliance on the highly polluting wet coal supply from the Springvale mine. Without this linkage, the extension risks perpetuating avoidable environmental harm across the region.

There is no justification for extending approval for up to 300,000 tonnes of coal transport by truck. Rail infrastructure already exists and must be made mandatory.
The continuation of thousands of heavy vehicle movements through the Blue Mountains and Sydney is unnecessary, disruptive, and environmentally irresponsible. Rail transport would significantly reduce diesel emissions, road wear, and community disturbance.

The claim of “no or negligible” impacts from trucking does not reflect lived community experience. More than 7,000 truck movements each year generate:
Persistent noise impacts
Traffic congestion
Diesel pollution
Increased road safety risks
These impacts are real and cumulative. They must be properly acknowledged and addressed rather than minimised.

Most coal extracted from Clarence is exported. If operations are to continue, supply should be prioritised for the nearby Mount Piper Power Station to avoid creating demand for new coal extraction from more environmentally damaging mines in the region.
Extending operations primarily to support export markets does not align with NSW’s climate responsibilities or regional environmental protection goals.

Existing rehabilitation commitments are outdated and inadequate by contemporary environmental standards. Any extension must impose modern, enforceable, and transparent rehabilitation requirements, including clear timelines, independent oversight, and meaningful penalties for non-compliance.
The community deserves assurance that damaged landscapes and water systems will be properly restored, not left as long-term liabilities.

Conclusion
Five additional years of coal extraction in the Gardens of Stone is not a minor procedural matter. It represents a continued commitment to fossil fuel expansion at a time when science, community expectations, and climate realities demand the opposite.
The proposal should be rejected. If approved, it must be subject to strict, enforceable conditions that prioritise environmental protection, community wellbeing, and a genuine transition away from coal.
I urge the Department to carefully consider the cumulative environmental impacts, the strong community concern, and the broader public interest in protecting the Gardens of Stone for future generations.
Yours sincerely,
Tanya Hardy

I strongly object to this proposal. I live in a community that has almost been annihilated by the coal industry. I also live in a country that is being environmentally annihilated by a shifting climate, we are only into 2 months of a new year and already we have seen massive flooding and bushfire destruction, and this destruction is happening all over the world.
In the proposal it was stated "the effects of planned and additional mitigation measures on GHG emissions have not been quantified given they are dependent on the outcome of further investigations" In the mean time ??????
Enough is enough

This proposal seeks to extend operations for another five years. At a time when we urgently need to reduce reliance on coal, approving extended coal extraction is the wrong direction for the Gardens of Stone region and for NSW.

Mining and burning coal prolongs the environmental damage already affecting our waterways. landforms and climate.

If the extension is approved despite community opposition, it must come with these five strict conditions:
1. Link approval to the upgrade of the Lidsdale coal unloader. This critical infrastructure would reduce reliance on the polluting, wet Springvale mine.
2. Reject the continued approval of 300,000 tonnes of coal by truck. There is no justification for extending years of heavy truck movements through the Blue Mountains and Sydney. Rail is available and should be mandatory.
3. Acknowledge the real impacts of truck transport. The claim of “no or negligible” impacts does not reflect the experience of communities dealing with noise, traffic, diesel pollution and road safety risks from over 7000 truck trips every year.
4. Prioritise local use over export. Most Clarence coal is exported. If extraction continues, it should supply Mount Piper Power Station to avoid pressure for new coal from more damaging mines in the region.
5. Strengthen rehabilitation requirements. Existing rehab commitments are outdated and inadequate. Any extension must impose modern, enforceable rehabilitation standards.

This is a critical moment. Five more years of coal extraction is not a minor administrative change — it is a significant decision for our environment, our communities and the Gardens of Stone.

Employment, Social and Economic Imperatives
Protecting Hundreds of Local Jobs
Approval of Mod 11 is essential to safeguard between 300 and 400 direct full-time equivalent jobs. These are secure, skilled, well-paid roles that sustain families, mortgages, small businesses and community services across the Lithgow region. Refusal would trigger immediate and irreversible job losses.
Safeguarding Lithgow’s Economic Foundation
Coal mining is the single largest employment sector in Lithgow LGA, injecting approximately $241 million annually into the regional economy. Mod 11 protects this cornerstone industry and prevents a sudden economic shock that would reverberate through local businesses, schools, healthcare services and community organisations.
Ensuring Energy Reliability During Transition
The project supplies essential fuel to Mt Piper Power Station, providing dispatchable baseload electricity at a time when NSW is transitioning to renewable generation. During this period of structural change, reliability and grid stability are critical. Mod 11 supports energy security when it is needed most.
Supporting Over 580 Additional Indirect Jobs
Beyond direct employment, the operation sustains more than 580 indirect roles across transport, equipment maintenance, contracting, manufacturing and professional services. The mine anchors a broad regional supply chain, generating substantial local procurement and economic multiplier effects.
Delivering Substantial Net Public Benefit
Independent cost-benefit analysis demonstrates clear and measurable public interest outcomes:
• $149 million in net social benefit to NSW
• $212 million in net benefit nationally
These are tangible, quantified benefits that would be forfeited if Mod 11 is not approved.
Maintaining Critical Public Revenue
The operation contributes significant state royalties, payroll tax and local council rates. These revenues directly support public infrastructure, schools, hospitals and essential services. Approval protects ongoing funding streams that benefit the broader community.
Strong Community Backing
Community consultation confirms clear local support for continuation of the mine. Residents recognise its long, stable operating history and its central role in sustaining employment, economic confidence and community cohesion.
Avoiding Avoidable Harm
Failure to approve Mod 11 would result in sudden job losses, business contraction, reduced household income and broader social disruption. These impacts are not theoretical — they are foreseeable and preventable. Approval avoids unnecessary hardship.
Consistent with Ecologically Sustainable Development
Mod 11 represents a balanced and responsible outcome, aligning environmental stewardship with economic stability and inter-generational equity. It achieves the objectives of Ecologically Sustainable Development by maintaining existing operations within already assessed and managed limits.
________________________________________
Environmental Responsibility and Compliance
No Significant Environmental Impacts
Comprehensive technical assessments covering traffic, noise, vibration, water resources, greenhouse gas emissions and socio-economic factors confirm that Mod 11 results in no significant adverse environmental impacts.
No Material Change to Noise or Vibration
Independent modelling demonstrates no meaningful change in community noise levels. Any minor exceedances (≤2 dB) are attributable to existing operations, fall within accepted regulatory frameworks and are effectively managed.
No Traffic Deterioration
Traffic impact assessments confirm that all intersections will continue to operate at acceptable Levels of Service (A–D) through 2031. No road upgrades are required and no adverse impacts on public road users are anticipated.
Protection of Groundwater and Sensitive Ecological Systems
Monitoring confirms no mining-related impacts on shallow aquifers or on the Temperate Highland Peat Swamps on Sandstone. Sensitive ecological values remain protected under existing management controls.
No New Land Disturbance or Biodiversity Impact
Mod 11 does not expand the mine footprint, introduce new infrastructure or require additional land clearing. There are no additional impacts on threatened species or ecological communities.
Full Regulatory Compliance
State agencies have confirmed the proposal remains “substantially the same development” under EP&A Act s4.55(2). The modification complies with all statutory requirements and remains within the scope of the approved project.
Demonstrated Environmental Management Capability
Existing, proven management plans for traffic, noise, water, greenhouse gas emissions and rehabilitation remain in force and will continue to be updated as required. The operator has demonstrated capacity for effective monitoring, compliance and adaptive management.
________________________________________
Conclusion: A Clear Public Interest Outcome
Mod 11 protects hundreds of jobs, sustains regional economic stability, secures energy reliability and delivers substantial net public benefit — all without introducing significant environmental impact or expanding the approved footprint.
Approval is not merely justified; it is a responsible, balanced and necessary decision in the public interest.

Community Member Submission

Re: Proposed Extension of Coal Supply for Mt Piper Power Station
I am writing as a local community member who has lived in the Lithgow area all of my life . Our region has a long history of supporting energy generation and mining, and these industries have played a major role in keeping our community strong. After reviewing the information about the proposed extension of coal production , I would like to express my support for the project.

Supporting Local Jobs and Businesses

Clarence Colliery mining operations is major employer in our area. Many families, including friends and neighbours, rely on these jobs. The project’s ability to support 300 direct jobs and around 1,100 indirect jobs is incredibly important for keeping people in work and maintaining the stability of our local economy.

Local businesses also depend on the activity generated by the mining operations. Protecting these supply chains helps ensure that small businesses, contractors, and service providers can continue to operate and contribute to the community.

Economic Benefits for Lithgow

The economic benefits outlined — over $212 million for Lithgow and $149 million for NSW — are significant. These funds help support essential services, local infrastructure, and community facilities. The continuation of royalties, payroll tax, and council rates is also vital for our region, especially at a time when many rural communities are struggling.

Maintaining Community Stability

The long-standing operation of the mine has been part of Lithgow’s identity for generations. Sudden changes or closures would create real social and financial disruption for many families. This project helps avoid that uncertainty by providing continuity and stability.

It also aligns with broader principles of sustainable development by balancing economic needs with social equity and responsible resource use.

Environmental Considerations

I appreciate that environmental impacts have been carefully assessed. The findings show no significant impacts in areas such as noise, vibration, water, methane, or social and economic factors. The small noise increases (less than 2 dB) are within accepted limits and relate to existing operations.

Traffic assessments also show that the road network will continue to perform well through 2031, with no upgrades required. This gives confidence that the project won’t create new issues for local residents.

Conclusion

As someone who cares deeply about the future of our region, I believe this project offers real benefits for the community. It supports local jobs, protects businesses, maintains important revenue streams, and continues a long tradition employment in Lithgow.

For these reasons, I support the proposed extension of coal production

I am writing to provide my support for the proposed Modification 11 (MOD 11) for Clarence Colliery.

I work in the Lithgow region and have a strong understanding of how important mining is to the local community. Mining is not simply one industry among many here — it is the economic foundation that supports families, small businesses and the continued viability of our towns.

A very large proportion of households in this area rely either directly or indirectly on the mining industry. Many residents are employed at the mine itself, while others work in transport, mechanical services, maintenance, trades, catering, fuel supply, retail, accommodation and professional services that exist because of mining activity. Local contractors and suppliers depend on ongoing operations to remain viable.

Without continued mining operations, the economic impact on the region would be immediate and significant. Businesses would lose customers, employment opportunities would reduce, and many families would be forced to relocate to larger centres to find work. This would lead to declining school enrolments, reduced local services and long-term social impacts for the community.

The Lithgow region has already experienced industry contraction in the past. Each time a major employer closes or reduces operations, it is clearly felt across the entire community — not just by mine employees, but by shop owners, tradespeople, real estate agents, hospitality workers and service providers. The mine supports a broad local economic network.

Importantly, the proposal does not introduce a new mining area or a new industry to the region. Mining has been part of the history and identity of the Lithgow district for generations, and the community has developed around it. MOD 11 allows the continuation of an existing operation that people have built their lives and businesses around.

Continuation of the mine provides:
Ongoing employment for local workers
Stability for local families
Security for local small businesses
Support for community organisations and sporting groups
Confidence for investment in the region

If the mine were to cease prematurely, the likely outcome would be population decline and economic contraction. Many workers would have no choice but to leave the area for employment, and once families relocate, they rarely return. This would have lasting impacts on the future of the community.

For these reasons, I support the approval of MOD 11. The project represents the continuation of an established industry that underpins the local economy and community stability.

I respectfully request that the Department give strong consideration to the social and economic importance of mining to this region when determining the application.

Mod 11 guarantees continued employment for approximately 300 full‑time equivalent workers, continuing to demonstrate coal mining to be the largest employment sector in the LGA. The project with support the essential supply of coal to Mt Piper for NSW energy security.
The project does not propose any significant environmental impacts as the MOD doesn't introduce any new surface disturbance or expansion to the mine footprint.
