No problems with any new Wild Cattle Creek tailing dams for antimony mining by-products arsenic and mercury, according to the China Shandong Jinshunda Group

One has to admire the chutzpah of mining corporation China Shandong Jinshunda Group Co Ltd as reported in The Clarence Valley Review on 29 June 2011:

Anchor Resources managing director, Ian Price, said the Dorrigo mine would operate under vastly improved practices to those carried out in the past.

“One of the key aspects is containment of any of materials from the particular site so they don’t enter waterways, or don’t go off-site.

I think that’s the critical thing, and that’s proper containment of tailings  in proper containment dams, and diversion of water around sites so they don’t enter the site … lots of old mining sites going back 50 or 100 years were not built with good tailings dams, and standards have developed over the past decades where those standards are much better,” he said.

First its spokesperson attempts to distance the mine from those North Coast local government areas in which residents are expressing concern, about the potential for negative environmental and public health impacts from mining for antimony and gold in a high rainfall, elevated and environmentally sensitive area within the Clarence and Nymboida river catchments, by calling it the “Dorrigo” mine.

Then the same spokesperson talks up modern tailing dams despite problems with these dams being experienced both in Australia and overseas and, finally he neglects to point out that the NSW Government allows mine owners to self-assess risk in relation to the design, construction and ongoing maintenance of the same tailing dams.

The primary goal of the DSC, relevant to this Guidance Sheet, is that all prescribed NSW tailings dam owners apply appropriate dam safety management practices to their dams using a risk management approach in line with a whole of Government approach to public safety.

Another goal is that risks to community interests from the potential for dam failure are tolerable, the owner’s determination in this regard being satisfactory to the DSC.

This requires that the risks are detected, identified and assessed, that they are reduced, when necessary, as soon as reasonably practicable and in a way that best  serves community interests, and that they are kept under review throughout the life cycle of the dams.

It is for each dam owner to determine how these goals, including DSC requirements, (see Section 2.2) will be achieved and to demonstrate that the goal has been achieved, or will be achieved following safety improvements. The following sections of this sheet aim to provide guidance to assist dam owners in the achievement of the DSC goals. [NSW Dam Safety Committee, June 2010, “Tailing Dams”,pp2-3]

Energy and Resources Minister Hartcher is a little economical with the truth

On the 29 June 2011 in an article titled Toxic metal hunt at proposed site State Energy and Resources Minister Chris Hartcher's position on any future mining proposal in the Wild Cattle Creek area of the Nymboida sub-catchment of the larger Clarence River catchment was elucidated:

“An exploration licence allows a company to undertake exploration, environmental assessments and feasibility studies only.”
Before any mine was opened strict guidelines had to be adhered to.
"Any future mining proposal would be required to obtain development consent through the relevant consent authority...As part of this process, proponents are required to prepare and submit a comprehensive environmental assessment that assesses all potential impacts of the proposal, including potential impacts on aquifers and water resources as well as cumulative impacts.”
Planning approval rests with the State Government until its plan to scrap Part 3A of the Planning Act is legislated.
Then it would be up to individual councils to sign off on any approval for the proposed mine.
“Local communities and councils are fully involved in the process, with planning approvals going out for public consultation,” Mr Hartcher said.

Unfortunately this is not the entire range of possibilities for progressing any future mining development application within the Nymboida or Clarence River catchment areas.

O'Farrell Government policy documents concerning the repeal of Part 3A of the NSW Environmental Planning and Assessment Act 1979 reveal that certain mining proposals will still fall into a category which can attract a State Significant Development (SSD) classification which allows the Minister to ‘call in’ a development application and possibly hand it back to the Planning Assessment Commission or over to the Department of Planning and Infrastructure for determination.

Should any mining proposal in the aforementioned catchment areas be ‘called in’ in this way then:

Under the proposed delegation, the PAC will determine larger and more controversial projects, while senior officers of the Department of Planning and Infrastructure will determine projects which have attracted fewer than 25 submissions by members of the public objecting to the proposal and where the local council has not objected.
[NSW Planning & infrastructure (June 2011) Environmental Planning and Assessment Amendment (Part 3A Repeal) Bill 2011: an overview]

This is a flow chart indicating the more likely route that any development application by China Shandong Jinshunda Group Co Ltd, Sunstar Capital Pty Ltd and Anchor Resources Ltd will take with regard to anitimony mining at Wild Cattle Creek.



Given the background of the mining corporation and Minister Hartcher's previously expressed sentiments on regional mining, I sincerely doubt that local communities will be more than a token consideration in any development determination.

Is Chinese Government policy encouraging mining in the Clarence River catchment in order to conserve its own national resources?

From North Coast Voices on 25 June 2011:

China Shandong Jinshunda Group Co Ltd as principal shareholder and new 'owner' of Anchor Resources Ltd (through its wholly-owned Australian subsidiary Sunstar Capital Pty Ltd) has been reported as having signalled its intention to mine for antimony in the Nymboida River sub-catchment of the larger Clarence River catchment.

The Australian Government’s National Pollutant Inventory recognises Antimony compounds show toxic properties similar to those of arsenic and sets its safe upper level in water at a maximum of 0.003 mg/L (i.e. 0.000003 g/L) in fresh water and 500 micrograms/L (i.e. 0.0005 g/L) in sea water.

The four mining projects this Chinese-owned mining corporation identifies in the Northern Rivers region are within an estimated 100 kms of Coffs Harbour and, post-takeover, the project at Wild Cattle Creek is 100% owned by Anchor Resources and its majority shareholder Shandong Jinshunda.

This mining group expects that mining processes at Wild Cattle Creek will produce mercury and arsenic as by-products, according to its own scoping study. This same study indicates mineral deposit potential in excess of 2 million tonnes.

Any accidental or adverse weather related catastrophic release of these toxic substances into the Clarence river systems could have longterm consequences for riverine ecosystems, public health and the local commercial fishing industry which supports an estimated 199 jobs and generates in the vicinity of $19.9 million annually.

On 23 June 2011 The Daily Examiner reported:Coffs Harbour's Greens councillor Mark Graham will table a notice of motion at today's council meeting calling for the prohibition of all antimony mining in the Nymboida River catchment, a move that is supported by Clarence Valley Mayor Richie Williamson.Cr Williamson said alarm bells should be ringing as the proposed location of the mine was in an extremely environmentally sensitive area of high rainfall.“With that environmental sensitivity comes a great deal of responsibility that the proposal meets the strictest environmental guidelines,” he said.He said the council would keep a very close eye on any developments involving the proposed mine. “We have invested greatly in the water which we drink and in the catchment,” he said.“We have worked closely with landholders and farmers along the riparian zone of the Nymboida River and its tributaries to ensure water quality has always been improved.”Similar to arsenic in its effects on human health, antimony is a toxic element.Use of the element is limited due to its toxicity, with the growth in micro-electronics seeing demand for antimony rapidly increasing. This demand has seen the price of antimony skyrocket by 300% in the past two years.

The Shandong Jinshunda Group is reputed to have no antimony mining experience and the Chinese Government’s Ministry of Land and Resources suspended (apparently for the third time since 1999) antimony exploration and mining applications until mid-2011, in an action designed to prevent over-exploitation and protect existing resources within its own national borders and possibly to address longstanding pollution concerns.

On 24 April 2011 China Daily reported China will not grant any new licences for prospecting or mining antimony until after 30 June 2012.

The Coffs Harbour City Council Ordinary Monthly Meeting 23 June 2011 NOTICE OF MOTION:

NOM11/14 PROHIBITING ANTIMONY EXPLORATION AND MINING AND PROTECTINGWATER QUALITY IN THE HEADWATERS OF THE REGIONAL WATER SUPPLY(NYMBOIDA CATCHMENT)

Purpose:
Councillor Mark Graham has given notice of his intention to move:
Recommendation:That Council:
1. Strongly oppose all exploration for, and mining of, Antimony within the catchment of the Nymboida River because of the unacceptable risks to the Regional Water Supply posed by these activities;
2. Inform all relevant authorities of this opposition including directly contacting relevant Ministers, Directors General and agencies with responsibilities for approval and regulation of such activities;
3. Seek the prohibition of all Antimony exploration and mining activities within the NymboidaCatchment to protect the Regional Water Supply from contamination;
4. Inform residents of the City of the unacceptable risks to drinking water quality posed by Antimony mining in the Nymboida Catchment;
5. Approach Clarence Valley Council to seek a partnership for protecting the Regional Water Supply from Antimony contamination.
Rationale:
The majority of the municipal water supply for Coffs Harbour is provided by Shannon Creek Dam, part of the Regional Water Supply Strategy shared with Clarence Valley Council. This 30,000 megalitre dam is located southwest of Grafton. It is an off-river storage reservoir gravity-fed by pipes directly from the Nymboida River. The Nymboida River has its headwaters across 1700 square km of the Dorrigo Plateau, an area renowned as the highest rainfall catchment in NSW.
Anchor Resources Ltd owns the Wild Cattle Creek/Bielsdown project within the headwaters of the Nymboida River, describing it as “an advanced Antimony project”. The company released a scoping study early in 2011 indicating that “positive financial returns are achievable from the project”. Anchor Resources Ltd is currently recommending that shareholders accept a takeover offer from the Chinese minerals company, China Shandong Jinshunda Co Ltd (Jinshunda).
Antimony is a “strategic mineral resource” used for a range of high-tech products such as polymers, fire retardants and electronics. Chinese national interests control over 90% of global supply of Antimony and they are seeking global dominance of all such strategic resources.
Antimony and many of its compounds are toxic; the effects of antimony poisoning are similar to arsenic poisoning. In small doses, antimony causes headaches, dizziness and depression. Larger doses damage the kidneys and the liver, causing violent and frequent vomiting and will lead to death within a few days; otherwise skin contact causes dermatitis. Major Antimony contamination is known from over 50km of the headwaters of the Macleay River to the east of Armidale, emanating from the Hillgrove and Bakers Creek Antimony and Gold mines.
Furthermore Urunga Lagoon immediately south of Coffs Harbour Local Government Area is heavily contaminated with Antimony as a result of a processing plant established there in the 1960s. Both areas have proven impossible to remediate and are gazetted as Contaminated Sites.
The proposal by Anchor Resources Ltd to undertake Antimony mining activities within the headwaters of the Nymboida River is of immense concern, particularly when considering that this catchment provides drinking and potable water for in excess of 100000 residents between Yamba and Sawtell. Of further concern is the extremely high rainfall in the Wild Cattle Creek sub-catchment, some years exceeding 3m of rainfall per annum. It is impossible to prevent migration of toxic minerals from mines established in such high rainfall areas, as evidenced by the high levels of contamination known from the Upper Macleay River, downstream of the Hillgrove Mine.
All efforts must be expended to protect the source of the Regional Water Supply from Antimony contamination, as clean water is the most critical resource for all life. A partnership should be established with Clarence Valley Council as a matter of urgency to prevent contamination of the Regional Water Supply with toxic Antimony.
Staff Comment:
The Executive Manager Coffs Water has compiled information regarding this issue and would be able to provide this to Council at a briefing.

It is understood that Coffs Harbour City Cr. Bill Palmer moved and Cr. John Arkan seconded a motion to defer consideration of Cr. Graham’s motion pending a briefing for councillors.

Local government and residents in the Dorrigo, Coffs Habour and Clarence Valley areas need to be proactive in their response to this proposal and those who are concerned at the prospect of mining within this environmentally sensitive catchment can contact China Shandong Jinshunda Group Co Ltd Chairman of the Board, Wang Gan, at sdjinshunda@sdjinshunda.cn and the NSW Minister for Mining and Agriculture Chris Hartcher at office@hartcher.minister.nsw.gov.au, as well as their own councils and state/federal members of parliament.Media Release 24 February 2011 Wild Cattle Creek Scoping Study Outcomes.

Regional Australia Committee Inquiry: Bourke favours Clarence River water diversion

From the Hansard transcript of the House of Representatives Standing Committee on Regional Australia’s Inquiry into the impact of the Murray-Darling Basin Plan on regional Australia - Bourke hearing on Tuesday, 15 February 2011:

Cr. John Holmes, Bourke Shire Council

There are other ways to rectify this river system than to starve out your little towns, which is going to happen. There has been mention of diverting water from the Clarence. Not only would you get water to shore up some of these rivers; you would also get another 28 meg of power.

Wayne O’Malley, former mayor of Bourke Shire Council

When talking about some sort of solution for the future, we need a fundamentally different approach. We need the conservation of more water to deal with the boom and bust nature of our climate. I put on the table again the diversion of the Clarence needs to be reconsidered, or at least some other major water infrastructure project not only for this part of the state but also for Australia. As a nation we have to be more mindful of our ever-increasing population, and we have to do more planning to provide water for them for the future.

Bourke Council was not alone in putting the case of the water raiders from over the Great Divide. During the hearing held at Gunnedah, the Citizen’s Electoral Council took this line with the Committee - rather strangely asserting that NSW flooding was confined to Grafton in 2010 and more oddly admitting that Bradfield was "not very bright":

Mr Witten

There are things such as the Clarence River scheme, which was mooted some 70 or 80 years ago by some idiot called Bradfield—and of course you know he was not very bright or did not have much ability. Nevertheless, he dreamt up a massive scheme to develop this nation…… The use of the Clarence River scheme, we believe, would inject around a thousand gigalitres into the system, plus provide electricity for our dying power supply.

Mr Stringer

We desperately need some of the eastern fall water up and down the New South Wales coast—and the Clarence is but one of these rivers; you have the rivers heading down towards Macleay. That water could come across to the Namoi, no problem. It is all going to waste. How many floods have we had in Grafton in 2009? How many floods in 2010? They are all in Grafton, and all the water goes to the sea, wasted.

North Coast Voices has some fun with Windsor's 'feral' jibe

Along with local politicians and media in the Clarence Valley, North Coast Voices had fun at Tony Windsor's expense with its feral edition:

Independent MP for New England Tony Windsor calls Clarence Valley residents 'feral' and Windsor labels Valley 'feral' ran headlines in both the mainstream media and blogosphere.

This was the swift response.....................

The Daily Examiner, 4 February 2011

Federal Labor MP for Page Janelle Saffin:"Well, too right we go feral because my view is they should just stop talking about an idea that's so stupid anyway; and it's not going to go anywhere. But we do go feral because everybody agrees that we cannot divert or dam the Clarence River.

NSW Nationals MP for Clarence Steve Cansdell: ..as far as damning and diverting the Clarence, I am happy to be classed as a 'feral'. I will always be against any such proposal.

Clarence Valley Mayor Richie Williamson: We do, and we will, go absolutely feral because a majority is clearly against the diversion or the damming of the Clarence River. We as a community are definitely against any damming of the Clarence River.

Boy the Wonder Cat: Tony Windsor doesn't know the meaning of 'feral' yet. If he keeps this dam nonsense up, one fine morning he will wake to find I've peed on his verandah posts, crapped on the front door mat, scared his hens eggless and bonked his dog so thoroughly that it won't come out from under the house for the next ten years.

Exchange between Ernest Kitta and Chair of the Inquiry into the impact of the Murray-Darling Basin Plan in Regional Australia Tony Windsor, at the Griffith hearing on Tuesday 25 January 2011

Mr Kitta—First of all, I have a couple of questions. What is the environment? It is a very loose term. In the dictionary it says the environment is your surroundings. I think that in Griffith here we are in the most beautiful surroundings you could have, so why take water away? You are taking water from the environment if you send it out to the lakes; you are not giving it to the environment at all. The other one—I am not an irrigation farmer—is that probably, when we get a good flood, some of the water comes in this direction, but by our dams and crops we have provided an environment for the roos and everything else that they would not have had before.This question has been raised quite a bit, and I will not go over it again, but I think it needs emphasising. It is the top end. They are working on the wrong end. They are rationing at the bottom end instead of increasing the supply at the top. The designs have been done for many years for these dams that the previous speaker mentioned. What they do is to go over to the Clarence River and tell the people there—real scare tactics—‘We’re going to take all your water and send it west.’ No such thing has ever been proposed. They proposed to take, I think, the flood waters of 30 per cent of the catchment. I think they would be quite happy to see the flood waters go; they had a flood recently. So it is plain political scare tactics to tell those people that there is no water to come over here. It has really had the lie given to it in Queensland now with the good flood they have had up there. Surely they would not miss a bit of water if they sent it down here. That is my whole point.

CHAIR—Thank you, Ernest. That site for the Clarence dam is in my electorate, and when you go over there and mention that they go absolutely feral! I will tell them you have endorsed it!

It's more pipelines, bigger dams and inter-basin water transfers

The Inquiry into the impact of the Murray-Darling Basin Plan in Regional Australia is being offered a wide range of options to ensure sustainable Murray-Darling Basin river systems.

Few of which admit to any need to limit current water consumption by reducing diversion caps and, some follow that tired old route of more pipelines, bigger dams and inter-basin water transfers.

Here are a few examples.

One option put forward by Wakool Shire Council in its submission:

Look at alternative supply for productive use – i.e.pipeline from river systems to high value use.

Another viewpoint from Lodden Shire Council:

The Authority should also consider the construction of environmental dams in key sites to store significant volumes of water devoted purely to environmental benefits. The cost of such infrastructure projects could be borne by all Australians or at least by those who will receive a direct benefit from the health of the Murray Darling Basin.

Carrathool Shire Council offered this:

New infrastructure projects, including additional and/or expanded water storages……….

Harvesting and redirecting surplus water resources from northern Australia.

While Hay Shire Council complained:

There is no possibility of any harvesting of additional water for the environment by the construction of additional dams or further investigation of diversion schemes. Such water would be harvested in wet periods such as we are now experiencing to be used in providing environmental flows as required in drier seasons. Why as a country are we not investigating this alternative?

Leeton Shire Council put forward these 'solutions':

Harvesting and re-directing surplus water resources form northern Australia and the eastern seaboard in Queensland and New South Wales;………

New infrastructure projects, including additional and /or expanded water storages, for example a new storage at Wellington in South Australia, or expansion of storages such as Lake Buffalo and Lake William Hovell in north east Victoria.

The Citizens Electoral Council informed the Inquiry that:

The proposed Clarence River Scheme would add upwards of 1,000 Gl/y of reliable flows into the Murray‐Darling Basin, which would transform the Basin's productive power.

Professional Fishermen's Association tells Regional Australia Committee: 'No A Drop!"

This is the text of the Professional Fishermen’s Association submission sent to the House Standing Committee on Regional Australia’s Inquiry into the impact of the Murray-Darling Basin Plan in Regional Australia in which the Association tells the Committee:

The following brief submission is referred to you for consideration by the Inquiry members.

Diverting the Clarence River is not an option in our view and any consideration of this should be rejected outright. The Clarence River is the base for the largest commercial fishery in NSW. Some 150 active commercial fishers catch a range of species in the river and offshore from the mouth of the river at different times of the year .The species include the following and are caught in varying quantities depending on seasonal conditions.

• eastern school whiting, stout whiting, sand whiting, flathead, bream, mullet, luderick, mud crab, blue swimmer crab, eel, herring, silver biddy, garfish, leather jackets, octopus, redfish, balmain bugs, deepwater bugs, cuttle fish, squid, (arrow, bottle and calamari), eastern king prawns, royal red prawns, school prawns, tiger and endeavour prawns, squid, snapper, pearl perch, morwong (red and rubberlip), yellow tail kingfish, bonito, long tail tuna, mack tuna, cobia, spanish mackerel, spotted mackerel, wahoo, mulloway, samson, sweep, amberjack, scorpio fish (red rockcod), tailor, tarwhine, trevally, teraglin, parrot fish, yellow fin tuna, bar cod, sand crabs, coral crab, red mullet (barbounia), pop eye cod, john dory, black tip and sand shark, yellowtail scad.

Many of these species spend part of their life cycle in estuaries including the Clarence and rely upon nutrients, water flows and the like to survive, reproduce and to maintain stock levels which in turn provides a range of sustainable fisheries in NSW. Fresh water flow is essential to the well-being of the river including ecosystem health and biodiversity within the river system.

One of the biggest fisheries on the Clarence is the Estuary Prawn Trawl (EPT) fishery. The catch varies, due to a range of reasons including freshwater flow levels, but averaged 375 tonnes per year over the past 25 years. The highest catch volume in that period was 597.9 tonnes in 1984/85 with 595.9 tonnes caught in 1988/89. The EPT industry relies on fresh water flow regime to stimulate growth, spawning and it greatly assists catch levels as the river is closed to trawling above the Ulmarra ferry.

Diverting water from the Clarence River will result in a decreased flow of freshwater and this combined with the tidal regime pushing saltwater further upstream will result in the fishery being destroyed as the stock will be upstream and outside the fishing area for the EPT.

The Clarence is also a large producer of finfish (mullet, bream, whiting, flathead, luderick), crab, eel and other seafood. The catch of these species averages about 500 tonnes per year. The reduction of the water flow, through diversion, and the subsequent decrease in nutrient loads will reduce the supply of seafood and will also impact on life cycle of the species in the river and immediately offshore.

The Clarence River fisheries are an important seafood supply source. With food security high on the agenda for Australia the commercial fishing industry on the Clarence and the adjacent ocean plays an important part of the food supply for this nation.

To replace the world’s fish catch by land grown meat, an area equal to twenty-two times the world’s rainforest would be required.

The commercial fishing industry on the Clarence is in the top two industries for output and employment. It is an extremely important industry for the social fabric of the Lower Clarence region. A recently completed socio-economic evaluation of the commercial fishing industry in the Clarence identifies the critical importance of the industry to the area. A copy of that report is provided for the Inquiry and the following two paragraphs are an example of the content of the report.

“The Lower Clarence area which is home to the majority of fishers in Northern NSW area has a fairly high level of socio-economic disadvantage, therefore the employment and income generated by the industry, though relatively small, remains important in the local economy. The long term connection of fishermen and their families to their local area suggests that they make up an important part of the local community and contribute to the social fabric of the towns they live in.

In a future where the sustainability and security of food resources will become so important, it is vital that the local commercial fishing industry is supported both by government and the wider community. People need to recognise the contribution of the industry to the provision of local and regional food security, and the efforts the industry has made to ensure that the harvest of resources remains sustainable. It is important that the productive capacity and the unique skill-set of commercial fishers are maintained. The development of new markets, value adding and the full utilisation of the harvested product will assist in maintaining the viability of the commercial fishing industry into the future.”

The commercial fishing industry on the Clarence generates $92M output, $15.4M income and, 431 employment positions.

The Professional Fishermen’s Association is fundamentally opposed to any diversion of water from the Clarence River. We support the Clarence community views that have been said repeatedly ‘not a drop’.

What the Clarence Valley is telling the new House Regional Australia Committee inquiry

Reported in The Daily Examiner on 14 December 2010:

With less than a week to go before submissions close for the inquiry into the impact of the Murray-Darling Basin Plan on Regional Australia, Clarence Valley environment groups are ensuring their voices are heard.

Clarence Environment Centre and Valley Watch Inc have both made submissions to the inquiry, which was set up to examine the human impact of the proposed Murray Darling Basin plan.

Of concern to both groups – as well as many others in the Clarence Valley – is the on-going call from some outside of the Valley to divert water from the Clarence River.

One Clarence Valley submission to the Australian Parliament House of Representatives Regional Australia Committee Inquiry into impacts of the Murray-Darling Basin Plan on Regional Australia talking about some of the unrealistic expectations which have been expressed this century:

When Malcolm Turnbull announced a feasibility study for the transfer of water from the Clarence to South East Queensland in early 2007, the Bourke Cobar, and South Australian Alexandrina Councils immediately launched their individual bids for a million megalitres per year, and 1.3 million megalitres respectively, to be diverted from the Clarence River.

So called facts and figures, and various methods to achieve the desired ends, were bandied about by everyone who had an opinion, regardless of their qualifications. Sydney Shock Jock, Alan Jones, led the charge for three days (that's as long as any one issue catches his attention), using the usual scientific measure of water in terms of 'Sydney Harbours' , “going to waste” out through the heads each day. One engineering firm claimed the entire transfer could be achieved by damming the river, and simply running the water downhill through a 20km tunnel with no pumping required.

What is evident in submissions received by the Committee from the Clarence Valley to date is the remarkable level of patience displayed in the face of yet another round of emotive calls by individuals and organisations in the Murray-Darling Basin to let them raid Clarence catchment fresh water and blithely ruin that coastal river system.
