Wongawilli MOD2 approved by DPIE, condemned by locals


19 April 2022

Wollongong, New South Wales — Protect Our Water Alliance condemns the latest approval for coal mining expansions within the Greater Sydney Water Catchment. Wollongong Coal’s Wongawilli Colliery has received NSW Government approval to build its North West Mains Development – a 7km long underground road beneath Avon Reservoir. Avon Dam is Sydney’s second largest dam, after Warragamba Dam, and is the only source of water supply to over 310,000 residents and businesses in the Illawarra region. 

The Department of Planning and Environment approval document notes that 90% of submissions opposed this expansion. 

Protect Our Water Alliance (POWA) spokesperson Rada Germanos said “Wollongong Coal admits they want to build this underground highway to access more coal deeper within our water catchment, and to keep their Wongawilli Colliery going for another 30 years.”

Wollongong Coal owns both the Russell Vale Colliery, and the Wongawilli Colliery, near Dapto. Both mines produce metallurgical coal, 100% of which is exported to its parent company in India. Wongawilli Colliery has been in care and maintenance mode since 2019, following a number of safety concerns forcing the closure of the mine. Prior to this closure, mine workers at the mine were amongst the most casualised and lowest paid in the state, with conditions improving only after a concerted union campaign.

“The NSW Government continues to approve coal mining expansions in this state, including beneath the water supply for Sydney and the Illawarra, leaving a legacy of  catchment damage, water loss and contamination, an eternal cost of mining for future generations to pay.”

“The upcoming decision to approve or reject the mammoth South32 Dendrobium Mine expansion will fall to the NSW Planning Minister after cynical legislative changes crushed the community and Independent Planning Commission decision. Will there be any public accountability on this next major decision, or will it be yet another bin fire example of a ‘captain’s pick’, with only the interests of mining corporations at heart?”

WATCH POWATalks #1 – The Essential Importance of Upland Swamps, with Dr Tanya Mason

Did you know? Coastal upland swamps are linchpins in essential ecosystem functions and biodiversity conservation. Dr Tanya Mason talks in this presentation about essential importance of upland swamps to the Sydney-Illawarra Water catchments. They capture and store rainwater, then release water slowly as base flow in dry periods. They level out storm hydrographs and extract excess nutrients in turn supporting and protecting Sydney’s potable water supply. Swamps capture large amounts of carbon through the accumulation of humus and peat and support unique biodiversity.

Long-wall mining dries out and reduces the biodiversity of upland swamps. There is no evidence that swamps ever recover. There are no known methods of rehabilitation. The best way to protect these crucial water capturing ecosystems is to stop long-wall mining.

A series of bite-sized talks with leading researchers on the wonders of the Greater Sydney water catchment and why it’s worth protecting.

We acknowledge the land that we live, work and join together to protect is stolen land. We pay our respects to elders past and present, and stand in solidarity with Dharawal, Yuin, Wodi Wodi and all First Nations people fighting for justice and self-determination.

Update and explainer: Dendrobium SSI process, what you can do, and upcoming POWA community information night

This is an update to POWA supporters and allies about the latest developments around the Dendrobium extension project and how to intervene in the planning process to protect our water and environment. As part of our response to South32’s new extension plan, POWA will be holding a public forum on January 20. We encourage you to come along and participate. (See details below)

As you may be aware, the NSW Government has recently declared the Dendrobium mine extension as State Significant Infrastructure (SSI), in spite of the Independent Planning Commission’s (IPC) rejection of the mine’s extension as a State Significant Development (SSD) in 2021. In February, the IPC decided to block the mine’s expansion because it would have unacceptable impacts to water security as well as biodiversity, threatened ecological communities and cause irreversible damage to 58 identified Aboriginal cultural artefacts and values. It also found the mine would cause serious degradation to 25 watercourses and swamps in the Metropolitan Special Area and release significant amounts of greenhouse gases.

The IPC’s decision to protect the water catchment and the environment was an important outcome for numerous ecological campaigns and for POWA as the main group opposing the project. 

Overturning the Independent Planning Process

The IPC decision was immediately condemned by coal corporation South32 and criticised by prominent members of the NSW Government, who vowed to overturn it. South32 and the NSW Minerals Council have been lobbying the government for months to overturn the Commission’s decision. In early December, NSW Deputy Premier Paul Toole and Planning Minister Rob Stokes announced they were pushing forward with the Dendrobium expansion. The decision to grant SSI status followed a motion on the issue in State Parliament, moved by One Nation, which was supported by the Liberals, the Nationals, the Shooters, Fishers and Farmers Party, the Christian Democrats, and the Labor Party. 

The Government has designated the mine State Significant Infrastructure due to its alleged role in providing coal for the Port Kembla steelworks. However, the IPC found that most of Bluescope’s coal came from other mines, the majority of Dendrobium coal over the next 20 years would be exported or transported elsewhere, and Bluescope’s preferred coal would not be mined by the expansion until almost 20 years into the project. Recently, BlueScope’s general manager of manufacturing David Bell told a ‘virtual town hall’ that work on the Port Kembla wharves would allow the steelmaker to bring in coal from elsewhere if need be. 

The IPC decision stated that the economic value of the water supply catchment and the costs of scope 3 greenhouse gas emissions was an equally important consideration as the coal & steel industry. The Government did not mention the water supply, environmental, or emissions concerns of the IPC in its statement about the SSI mine expansion plan. 

As POWA continues to highlight, what the Illawarra needs is renewable energy, green steel, and a just transition, not another coal mine. This is where sustainable jobs and incomes will come from.
The new plan would extend the life of the Mine to 2041 and would involve the extraction of millions of tonnes of coal each year. This is the first time that a coal mine has been declared State Significant Infrastructure in NSW and would set an alarming precedent.

Crucially, the SSI declaration removes the IPC and any independent decision-making body from the approval process, making the NSW Minister for Planning and Homes the consent authority for the project. The Planning Department previously recommended that the IPC approve the project and the planning minister has now given himself the power to decide on this project. The removal of independent oversight calls into question the role of IPC and the Department of Planning, Industry & Environment (DPIE) and suggests the ‘capture’ of the State Government and most NSW political parties by coal companies. It is untenable for the DPIE to do the assessment of this project since they previously backed the flawed claims by South32, which were rejected by the IPC.

Extension Impacts

The powerful campaign opposing extended mining at Dendrobium has resulted in a revised plan, which is less destructive than South32’s original proposal. Due to our collective efforts the proposed longwalls have been reduced by half, which would potentially involve less damage to the water catchment, and have a reduced impact on Aboriginal heritage areas, with six sites to be directly undermined, compared with twenty-two previously. Nonetheless, POWA continues to oppose any mining in the water catchment, as well as the other destructive impacts of the extension proposal. These impacts include – 
– Perpetual surface water loss
– Undermining of streams & swamp
– A range of other risks to local ecology and biodiversity
– Undermining of at least six Aboriginal heritage sites
– Greenhouse gas emissions
– Increased danger of bushfires

The SSI assessment process

When an application is made for the Minister’s approval for SSI, the Planning Secretary prepares environmental assessment requirements, or SEARs, for the project. The Department published the SEARs for the proposed extension just two days before Christmas.
The SEARs identify the information that must be provided in the mining corporation’s Environmental Impact Statement (EIS), including the matters that require further assessment and the community engagement that must be carried out during the preparation of the EIS. 
What preparing an Environmental Impact Statement (EIS) typically involves:
In normal process, the preparation of an EIS usually involves the proponent (in this case South32):
• Engaging with community
• Undertaking detailed technical studies to assess the impacts of the project in accordance with any relevant Government legislation, plans, policies & guidelines
• Refining the design of the project to avoid or minimise the impacts of the project.

The preparation of the EIS should involve a process of impact assessment and design refinement, development of mitigation measures & consultation with community, stakeholders and government agencies.
The Dendrobium Mine Extension Project must take into account the issues raised by the IPC in its refusal of the project and should be subject to a whole of government merit assessment in accordance with the requirements of the Environmental Planning and Assessment Act 1979.

Public exhibition & submissions

Once complete, the EIS will be checked by the Department before being placed on public exhibition for a minimum period of 28 days.
During the exhibition period, anyone can make a written submission on the EIS.
POWA has many questions and concerns about the Dendrobium SSI Process.
We remain opposed to the impacts on the water catchment and the environment as listed above.

Regarding this new and unprecedented process for mine approval, we think it is very important that the community has answers to the following questions:

1. Will NSW DPIE publish their final assessment report for the project and allow opportunity/time for the community to get expert critiques of the document prior to the Minister’s decision?  

2. Who will write the DPIE Final Assessment Report?   

3. Will the writer of the new DPIE Final Assessment Report assess South32’s EIS from an ecological sustainable development perspective as required by the NSW EP&A Act?

4. The economic analysis commissioned by the DPIE to assess the Dendrobium Expansion Environment Assessment was rejected by the IPC, particularly around the reliance of Bluescope Steel on the project. So, who will conduct the investigation and assessment of the importance of local coal supply to BlueScope Steel?  And what are the terms of reference for that?  

5. Who will conduct the economic costs/benefits assessment of the revised project? Will DPIE ensure that this work will go through a rigorous tender process where the credibility of any would-be contractor is thoroughly vetted?  Will DPIE ensure that it does not provide a biased brief or Terms of Reference to the contractor?  

6. Will the NSW DPIE uphold the current requirement of the koala SEPP 2020 for habitat value in its assessment of South32’s EIS?

7. Can the community be confident that the criticisms of the previous economic assessments (or economic assessment reviews) made by experts who appeared on behalf of POWA to the IPC, will be thoroughly addressed so that the same errors are not present?   

8. What are the community’s appeal rights related to any decision the Minister makes on the project?

What do we know about the new Dendrobium Mine Extension proposal?

Information is taken from South32’s Scoping Report on the DPIE Major Projects website

  • South32 is seeking to extend into “Area 5” — the plan to mine “Area 6” has been abandoned
  • The proposal seeks to extend the life of the mine until 2041 (previously 2048)
  • South32 have redesigned the proposal to try and address concerns about impacts to the water catchment
  • Longwall width appears unchanged — previously proposed as 305 metres wide, with narrower longwalls identified as far less destructive but uneconomical for the mine
  • South32 will continue to undermine streams, upland swamps, and identified Aboriginal cultural heritage sites

While it is clearly undemocratic that this project has been given SSI status following clear opposition from the local and scientific communities, it is obvious that this has had a significant impact on this revised proposal.

The initial detail of these amendments to the proposal are as below — taken directly from the Scoping Report:

• approximately 60% reduction in longwall mining area;

• approximately 60% reduction in surface water losses (from the previous application);

• no predicted connective fracturing from the seam-to-surface when using the Tammetta equation;

• no longwall mining beneath 3rd, 4th and 5th order (or above) streams;

• approximately 50% reduction in the length of 1st and 2nd order streams longwall mined beneath;

• approximately 40% reduction in the number of swamps (listed as threatened) longwall mined beneath;   

• commitment to avoid longwall mining beneath identified key stream features;   

• reduction in number of previously identified Aboriginal heritage sites directly mined under from 22 to six sites (with the likelihood of direct impacts to these six sites expected to be approximately 1 in 10 based on extensive monitoring of subsidence-related impacts to heritage sites);   

• no longwall mining beneath previously identified high archaeological significance Aboriginal heritage sites;   

• increased longwall mining setback distance (at least 400 m) from the Avon River, Cordeaux River and Donalds Castle Creek;   

• minimum longwall mining setback distance of 300 m from the Full Supply Level of the Avon Dam;

• minimum longwall mining setback distance of 1,000 m from dam walls; and       

• use of existing infrastructure (namely the Dendrobium Pit Top, Kemira Valley Coal Loading Facility, Kemira Valley Rail Line, Dendrobium CPP, Shaft Sites Nos 1, 2 and 3 and the West Cliff Stage 3 Coal Wash Emplacement) which would reduce the requirement for additional disturbance

Media release: Community group condemns reclassification of Dendrobium Mine expansion as State Significant Infrastructure

Wollongong, New South Wales — Community group Protect Our Water Alliance is outraged at the NSW Planning Minister’s decision to grant South32’s Dendrobium Mine extension State Significant Infrastructure status. This backflip on the government’s own processes is unprecedented. It comes after the proposed 25 year expansion was rejected by the Independent Planning Commission in February, citing concerns about the impact of the expansion on the Greater Sydney Water Catchment. 

Protect Our Water Alliance (POWA) spokesperson Dr Rada Germanos said “How can our community trust in government processes? Reclassifying this proposal as SSI limits the community’s access to critical information, and extinguishes the right to appeal a decision.”

“Serious concerns about this project from the scientific community, local residents, and Traditional Owners have been voiced. These concerns were listened to by the IPC when they rejected this proposal. This decision by Minister Stokes has betrayed the local community, as well as the government’s own processes.”

The proposed 25 year expansion of longwall mining would see over 8 billion litres of water annually lost from the Greater Sydney Water Catchment, and over 250 million tonnes of CO2-equivalent emitted over the life of the mine.

“We are only a month past the latest COP conference in Glasgow, and here we see the State Government again rolling out the red carpet for horrifically destructive mining companies. South32 will continue to rip and ship coal for private profits, while our communities suffer the consequences of greenhouse gas emissions and a trashed water catchment.”

“This area supplies water to 5 million people. Let’s talk about what is really significant here. We can’t drink coal. We shouldn’t be undermining this critical catchment.”

POWA is a grassroots community group committed to defending the water security of our region. For more details about this campaign visit –

Dendrobium Mine Expansion given ‘State Significant Infrastructure’ status by NSW Govt

Following rejection of the South32 Dendrobium Mine Extension proposal by the Independent Planning Commission in February 2021, the NSW Government has granted the proposal State Significant Infrastructure (SSI) status. This effectively overrules its own independent planning approvals processes.

SSI status means that the Planning Minister will have the final say in approving or rejecting the project, with no right of appeal open to the community.
