Now Showing: Pebble Mine’s Disastrous Future at BC’s Mount Polley Mine – by Joel Reynolds (Huffington Post – August 7, 2014)

http://www.huffingtonpost.ca/

Joel Reynolds is the Western Director and a senior attorney in the Los Angeles office of NRDC.

In the early morning of August 4, 2014, a major breach occurred in an earthen dam built to contain millions of tons of mining waste — called “tailings” — at the Mount Polley copper and gold mine in central British Columbia. Now, three days later, an estimated 1.3 billion gallons of contaminated tailings have spilled from the breached pond, sweeping untold volumes of waste and debris into the salmon stream and lake systems in the region and potentially threatening the Fraser River system to the west.

Previously pristine fishing, swimming, and summer vacation destinations like Polley Lake, Hazeltine Creek, and Quesnel Lake — including drinking water sources for the surrounding communities and residents — are now ground zero for toxicity, government health warnings, and “clean-up” – if indeed such a thing is actually possible.

Right now, before our very eyes through horrifying YouTube video, we are witnessing the mine disaster that the communities of Bristol Bay have feared — their “worst nightmare” — from the massive Pebble Mine. It is the toxic time bomb explosion that all of us who’ve fought the Pebble Mine have predicted could happen.

It is the catastrophic impact that, in its Bristol Bay watershed assessment, the EPA described as foreseeable in the event of a “tailings storage facility failure” — in layman’s terms, a dam breach — a finding the Pebble Limited Partnership (and its sole remaining company Northern Dynasty Minerals) have resoundingly and repeatedly challenged as groundless, as bad science, as a violation of their “right to due process.”

Group calls for government inspections of Sask. mine ponds (CBC News Saskatchewan – August 07, 2014)

http://www.cbc.ca/news/canada/saskatchewan

Mining companies currently hire independent consultants and present those reports to government

On the heels of one the the worst spill disasters in Canadian history, some people in Saskatchewan are worried about how this province protects and regulates tailings ponds.

It comes after the Mount Polley Mine tailings pond wall collapsed in B.C. Water, contaminated from years of mining, is flowing into nearby lakes and rivers.

In Saskatchewan, mining companies hire consultants for tailings pond inspections. Those reports are passed on to the Ministry of Environment for review.

Peter Prebble of the Saskatchewan Environmental Society said he would prefer the government do its own inspections of the tailings ponds and not rely solely on the company’s reports.

“There’s been a real tendency in Saskatchewan to encourage self regulation by companies, in other words, to encourage them to take more responsibility for ensuring that regulations are met. I’m worried that we’re moving too far in that direction,” he said.

In B.C., a total of 10 billion litres of water and 4.5 million cubic metres of metal-laden sand has leaked out of the tailings ponds.

No reason to be confident in environmental protection – by Barbara Yaffe (Vancouver Sun – August 7, 2014)

http://www.vancouversun.com/index.html

Missteps give B.C. residents no reason to trust companies or government

Could there be a worse time in B.C. to have a tailings pond disaster?

Never mind that the salmon are spawning. A wee debate is taking place in this province about whether to sanction a pipeline to the coast and tanker transport of bitumen along B.C.’s coastline.

Albertans, hoping to get their petroleum to the West Coast, must be as distressed as British Columbians at the Aug. 4 breach of the Mount Polley tailings pond. Or they should be.

That is because this environmental catastrophe is bound to have a chilling effect on those in B.C. who otherwise might have been open to being convinced that — should Enbridge comply with the province’s five conditions and the 209 imposed by a federal review panel — well, maybe the job-generating Northern Gateway project would be worth the presumably diminished risk.

Not now. A slurry of metal-laden sand and waste water from that Imperial Metals tailings pond could well be mistaken for bitumen, with its greyish colour and ability to carry timber and other detritus along with it on its determined path.

This is what happens when goop mixes with water. A water ban, barring both drinking and bathing, was put in place in the vicinity of the breach and aboriginal fishers now fear for the season’s salmon run.

Company behind Mt. Polley disaster to open mine near Southeast Alaska Fishermen, Native groups concerned – by Anna Bisaro (The Juneau Empire – August 8, 2014)

http://juneauempire.com/

After the tailings pond dam breach at Mount Polley on Monday morning, Southeast Alaskans are worried about another Imperial Metals Corporation mine already being constructed at the headwaters of the Stikine watershed, one of the largest salmon producers in the Tongass National Forest.

The Red Chris Project, an open-pit copper and gold mine, is being constructed in northwest British Columbia near the Iskut River, a major tributary of the Stikine River. The Red Chris is predicted to process almost 30,000 tons of ore per day for 28 years, according to the Imperial Metals Corporation website.

“In Southeast Alaska, we will absorb nothing but risk,” Brian Lynch of the Petersburg Vessel Owner’s Association said. “We have everything to lose and nothing to gain.”

Lynch said that, after Monday’s incident, the fact that the Imperial Mines Corporation is also at the helm of the Red Chris Project increases concern for the Stikine watershed. The Stikine is an important salmon-producing river for the Tongass National Forest.

“A breach like this would be a disaster,” Lynch said of the Red Chris Project. “These systems produce a lot of salmon for our billion-dollar-a-year industry.”

Rio Tinto’s Kitimat aluminum smelter upgrade price tag rises to US$4.8 billion – by Ross Marowits (Canadian Business – Aug 7, 2014)

 http://www.canadianbusiness.com/

The Canadian Press – MONTREAL – Rio Tinto will pump another US$1.5 billion into the aluminum smelter upgrade at Kitimat, B.C., increasing the total project cost to US$4.8 billion, as the mining giant says it remains confident about long-term fundamentals about metal demand.

The London-based company announced Thursday that its board has approved a further $1.5 billion expenditure to complete the modernization. That’s on top of $400 million that was previously allocated but unspent.

Rio Tinto Alcan’s former CEO Jacynthe Cote had said that difficulty in finding the right workers pushed the project off schedule and over budget.

There are about 1,100 employees at Kitimat and nearly 3,000 people working on the smelter upgrade, which is expected to start metal production in the first half of 2015.

Engineering, procurement and construction is 70 per cent complete but construction is only half finished, spokesman Bryan Tucker said Thursday.

The company announced in 2011 that it would upgrade the aging Kitimat smelter, boosting its aluminum production capacity by more than 48 per cent to about 420,000 tonnes per year.

Dam Burst Threatens Canada Projects Seeking Approval – by Christopher Donville and Liezel Hill (Bloomberg News – August 08, 2014)

http://www.businessweek.com/

A dam failure that sent billions of gallons of mine waste flowing down a British Columbia creek threatens to put a chill on new mining projects across Canada.

The Aug. 4 accident at Imperial Metals Corp. (III)’s Mount Polley copper-and-gold mine led the local district authority to declare a state of emergency amid concerns about drinking water and the fate of millions of migrating salmon. Provincial government officials are at the mine, about 400 kilometers (248 miles) northeast of Vancouver, and are testing local rivers and lakes for contamination.

The dam breach has been stabilized and the waste isn’t acidic, Vancouver-based Imperial said in a statement the day after the accident. The company is trying to investigate the spill and mitigate its effects, it said yesterday.
Whatever the cause or final outcome of the accident, it’s already bad news for the mining industry, which accounts for about a fifth of Canada’s exports. Mines trying to obtain permits in British Columbia will now be scrutinized much more closely, Adam Low, an analyst at Raymond James Financial Inc., said in an interview.

“This will, I think, cause everyone in government across the country to re-examine policies,” Bill Bennett, the province’s minister of energy and mining, told reporters Aug. 6.

B.C. orders cleanup after mine waste discharged into waterways – by Andrea Woo (Globe and Mail – August 7, 2014)

The Globe and Mail is Canada’s national newspaper with the second largest broadsheet circulation in the country. It has enormous influence on Canada’s political and business elite.

VANCOUVER — Three months ago, the Mount Polley mine experienced a small, but notable, breach that was quickly corrected when the gold and copper operation “got itself into compliance,” according to the province’s mines minister.

But environmental advocates say the incident should have served as a warning to avert the massive tailings-pond failure this week that has spewed millions of cubic metres of potentially contaminated waste into central British Columbia’s waterways, a disaster believed to be the largest of its kind in Canadian history.

The Mount Polley tailings pond damn burst early Monday morning, spewing enough mining waste water into the Cariboo district’s waterways to fill 2,000 Olympic-sized swimming pools. The Cariboo Regional District declared a local state of emergency; up to 300 residents in the rural community of Likely remain without clean water for drinking or bathing.

On Wednesday, the B.C. government ordered Imperial Metals Corporation, which owns the mine, to undertake an environmental impact assessment and submit cleanup plans to the Ministry of Environment.

The exact cause of Monday’s rupture is under investigation. There are three inspectors on site and two consulting companies are working with the Ministry of Energy and Mines, Minister Bill Bennett said.

First Nations fear the worst for B.C.’s salmon run following Mount Polley breach – by Sunny Dhillon (Globe and Mail – July 7, 2014)

The Globe and Mail is Canada’s national newspaper with the second largest broadsheet circulation in the country. It has enormous influence on Canada’s political and business elite.

VANCOUVER — The exact effect of the Mount Polley spill on B.C. salmon is not yet known, but with the sockeye just entering the Fraser River – and more than one million fish heading directly for the region hit by the mining waste – First Nations and conservation groups are fearing the worst.

Concern about the sockeye’s survival and whether the fish is safe to eat has emerged as another front in the resource battle between First Nations and governments, with aboriginal leaders charging the mining industry has lacked oversight, and questioning the point of the right to fish when the salmon is contaminated.

Bev Sellars, chief of the Soda Creek Indian Band, likened the area touched by the spill to a spiderweb. “When you disturb one part of the spiderweb, it affects all of it. That’s how this mine is going to affect everything,” she said in an interview Wednesday.

Ms. Sellars said test results and data have not yet come in, but the spill will certainly lead to some dead fish. “How could there not be?” she asked. She said members of her community have already seen dead salmon.

Approximately 1.5 million sockeye had been expected to head to the Quesnel region this year. About 20 per cent are believed to have already entered the Fraser River as part of their journey, with the rest expected to begin the trek north by the end of the month.

Mt Polley: The Cost of Moving Forward – by Jack Caldwell (I Think Mining.com – August 6, 2014)

http://ithinkmining.com/

Jack Caldwell, P.E. has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Canada and the United States.

In one of the many article I read on the Mt Polley tailings failure was an estimate of what it will cost to get the mine going again. A figure of $50 million was quoted as the cost to pick up all the tailings and return them to the tailings facility. I imagine that figure is based on five million cubic meters of tailings at about $10 a cubic meter to pick up. Here is why I suspect the figure is grossly low.

In conventional civil or mining earthworks $10 a cubic meter would be generous. But the material to be picked up is still a near-fluid. It will slosh around in the truck and spill out through the opening in the truck bed. Also the bottom of the creek now covered with tailings is by no means uniform. It is probably rough and rugged and teaspoons will be required to pry the tailings out of every nook and cranny. So let us double the cost of picking up the tailings and taking them back to the facility.

While it will not be easy to pick up the tailings strewn along the creek, it may be impossible to get back the tailings in the lake. Do you dredge the lake? Of course you can dredge, but then you will pick up a lot of clean bottom sediment along with the tailing. Inevitably they will have to consider placing a subaqueous cover on top of the tailings in the lake. This was done off the coast of Los Angeles to cover PCB sediment on the ocean floor, so it could be done in BC. But at what cost? Say another $100 million.

Next the tailings facility breach has to be repaired so that the returned tailings will stay there. That means plugging the breach. I am not sure I would let a workman go near those steep slopes that subtend the failure zone.

The Risky Rise of the [Mine Tailings] Dams – by Andrew Nikiforuk (The Tyee.ca – August 7, 2014)

http://thetyee.ca/

A massive mining wastewater spill in the interior of British Columbia highlights a new global trend: tailing dams that hold waste are not only getting bigger, but posing greater risks to watersheds and communities downstream.

Drawing upon recent industry reports and presentations made by engineers living in the province, it’s clear that the complexities of the industry have multiplied and with them, risks to water are escalating.

Increased global mining production of substances such as iron ore, gold, copper and nickel along with rising metal prices has tripled the value of the industry from $200 billion to $600 billion over the last decade.

But due to declining ore quality, the sheer volume of waste produced by the industry, which can contain substances such as arsenic, lead and cyanide, is increasing.

Every year, the industry digs and moves as much solid rock (several thousand million tonnes per year) as all earthen materials transported by natural geological processes, such as landslides and erosion.

Because of the challenge of peak metals and high global demand, the mining industry faces a number of somber risks, as reported by Andrew M. Robertson of Robertson GeoConsultants at a recent mining conference.

Editorial: Mount Polley tailings spill – Imperial’s best not good enough – by John Cumming (Northern Miner – August 6, 2014)

The Northern Miner, first published in 1915, during the Cobalt Silver Rush, is considered Canada’s leading authority on the mining industry. Editor John Cumming MSc (Geol) is one of the country’s most well respected mining journalists.  jcumming@northernminer.com

The complete failure of the tailings dam at Imperial Metals’ Mount Polley copper–gold mine in Central B.C.’s Cariboo region on Aug. 4 is the most depressing thing to have happened in Canadian mining since the Bre-X Minerals debacle in 1997. It’s the worst tailings dam failure tied to a Canadian company since the Los Frailes disaster in Spain in 1998 (5 million cubic metres spilled) and the Omai spill in Guyana in 1995 (2.3 million cubic metres spilled).

It’s about as big a tailings dam failure as you can get: some 15 million cubic metres of tailings muck has so far flowed out of the mine’s tailings-impoundment area through a gaping hole in an obliterated eastern portion of a huge dam wall.

To see the jaw-dropping scale of the devastation, watch the full video of a helicopter survey of the affected area at http://youtu.be/M1YgX2jXnpA, posted by the Cariboo Regional District authority. The video takes 37 minutes, because the affected area is so huge: the massive tailings facility itself, Polley Lake immediately to the east and the deeply messed-up Hazeltine Creek, which empties into the western reaches of the formerly pristine Quesnel Lake, where there are critical salmon-spawning grounds.

In the video, huge amounts of material is actively flowing out of the tailings facility in great, muddy torrents into Hazeltine Creek. Have you ever seen a waterfall of mine tailings? It’s here in this video, in the middle of Hazeltine Creek — a formerly 1-metre wide trickle of wending water that is now a scoured-out 45 metres wide.

Mount Polley mine tailings spill: Imperial Metals could face $1M fine (CBC News British Columbia – August 06, 2014)

 

http://www.cbc.ca/news/canada/british-columbia

Company ordered to stop pollution immediately and provide environmental impact assessment

Bill Bennett, B.C’s minister of energy and mines, says Imperial Metals will have to acknowledge and pay for any mistakes that led to the massive breach earlier this week of the tailings pond at its mine in central B.C.

The breach of the tailings pond dam at the copper and gold mine near Likely, B.C., released 10 billion litres of water and 4.5 million cubic metres of metals-laden fine sand, contaminating several lakes, creeks and rivers in the Cariboo region on Monday.

Speaking at a news conference Wednesday afternoon, Bennett said a pollution abatement order had been issued to Mount Polley Mining Corp., owned by Imperial Metals. If the firm does not comply, it could face fines of up to $1 million.

“If the company has made some mistakes… they will have to bear the responsibility,” Bennett told reporters in Williams Lake.

Tailings ponds for mining and oilsands waste: FAQs (CBC News – August 05, 2014)

http://www.cbc.ca/news/technology

What’s in them, what makes them risky and how they’re regulated

The breach of a tailings pond at the Mount Polley copper and gold mine in B.C. has released 10 billion litres of mining wastewater into local waterways in early August. Local residents have been banned from using the water from the Quesnel and Cariboo river systems.

Here are the answers to some questions you might have about tailings ponds.

What are tailings?

Tailings are the byproducts left over from mining and extracting resources, such as extracting bitumen from the oilsands or minerals such as copper or gold from ores. Tailings include:

  • Finely ground rock particles – ranging from sand-sized to silt-sized.
  • Chemicals used to extract the valuable mineral or oil.
  • Water.

Mount Polley Mine tailings water ‘very close’ to drinking quality, company says – by Rhiannon Coppin and Bal Brach (CBC British Columbia – August 5, 2014)

 

http://www.cbc.ca/news/canada/british-columbia

Imperial Metals president Brian Kynoch says he would drink water from tailings pond that leaked into rivers

Imperial Metals president Brian Kynoch says the company accepts full responsibility for the breach that caused a massive failure at the Mount Polley Mine in central B.C. on Monday and sent billions of litres of wastewater into river systems.

“I apologize for what happened,” Kynoch said at a news conference plagued with technical problems in Likely, B.C., on Tuesday afternoon. “If you asked me two weeks ago if this could have happened, I would have said it couldn’t.”

Wastewater and tailings sediment from Imperial Metals’s Mount Polley copper and gold mine near Likely has contaminated several lakes, creeks and rivers in the Cariboo region, causing officials to evacuate local campgrounds and enact a number of water-use and drinking water bans.

Mt Polley Tailings Failure: Lies versus the Truth – by Jack Caldwell (I Think Mining.com – August 6, 2014)

http://ithinkmining.com/

Jack Caldwell, P.E. has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Canada and the United States.

Today we have read all we can find on the failure of the Mt Polley tailings facility. It is all distressing. And mostly misleading. Here are a few clear thoughts on the topic.

The videos show that the tailings and water are still pouring out of the failed facility. Problem number one is how do you stop this flow. I do not know how I would stop the flow and nobody seems concerned to stop the flow. But more tailings and contaminated water are escaping as we write. If it rains, even more will be washed out. Demand number one is an answer as to how continued tailings flow will be stopped.

I can accept that the water and all it nasty constituents will be diluted by the rivers and lakes into which the water is flowing. But what of the solids? They are in the river, on the banks, and now in the lake. Will it ever be possible to clean this up, or will these tailings have to be allowed to wash by rain into the lake to join the bottom sediments? Maybe we need to build an emergency dam up-river of the lake to catch the solids.

Imperial Metals is saying the area affected is small by comparison with the area of the tailings facility. This is true, but irrelevant. Until they stop outflow, the threat of all the tailings to the environment remains.
