Water quality in a tributary of one of Southeast Alaska’s prime salmon rivers will improve once a new mine opens on the B.C. side of the border according to spokesmen for Seabridge Gold Inc, the Toronto-based company planning to open the Kerr-Sulpherets-Mitchell (KSM) mine.

The copper, gold and molybdenum mine, 65 kilometres northwest of Stewart and 30 kilometres from the Alaska border, received federal and provincial environmental assessment approvals last year and the company is now seeking a joint venture partner for the $5.4-billion project.

But the prospect of a massive mine close to a tributary that runs into the Unuk River has alarmed Alaskan fishing, First Nations and environmental groups who say the risk is unacceptable and are pushing for transboundary mining issues to be referred to the International Joint Commission.

“The long term risks of KSM far outweigh any short-term improvements to water quality the mine may create,” Chris Zimmer, Rivers Without Borders Alaska campaign director, said.

The KSM tailings pond, with a massive 239-metre tailings dam, will be built in the Bell Irving/Nass watershed in B.C., but the mine operation will be close to Sulpherets Creek which runs into the Unuk River.

“The open pits and waste rock piles are located in (the Unuk) watershed,” Heather Hardcastle of Salmon Beyond Borders said.

“They’re essentially using the Unuk, all the way up to the border as a mixing zone.”

However, Brent Murphy, Seabridge Gold vice president environmental affairs, in an interview with DeSmog Canada, said water quality in the creek is already bad because of natural erosion of copper, iron and zinc deposits.

“The acidity will basically eat your boots off,” he said.

Federal and provincial regulators agree there will not be any impact in Alaska from the mine, Murphy said.

“The operation of the KSM water management system will, in fact, improve the overall water quality,” he said, pointing to company photos of discoloured creek water.

“We will treat the water that comes into contact with the mine site and improve the water running into Sulphurets Creek and ultimately the Unuk River,” Murphy said.

But Alaskan groups say the photos are misleading and point to a 2014 report by Skeena Wild Conservation Trust that concluded KSM would release metals into the Unuk watershed that would exceed levels known to have serious impacts on salmon.

“I am especially concerned when people make statements to the effect that they can improve natural systems. Seems the height of hubris,” said Guy Archibald, Southeast Alaska Conservation Council, Inside Passage waterkeeper coordinator.

“There is more complexity in a mud puddle than science will ever understand and a massive intervention such as the KSM mine will no doubt have massive unforeseen negative consequences.”

Following the 2014 collapse of the Mount Polley tailings pond dam there has been increased concern about earthen tailings dams and the expert panel looking into the disaster recommended that mining companies should adopt best available technologies and consider dry stacking tailings when possible.

However, Peter Williams, Seabridge vice-president of technical services said location is the paramount concern when choosing how to dispose of tailings and, after considering dry stacking, it was decided the KSM site was ideal for wet tailings, with a lined tailings pond to ensure no discharge into the environment.

“We have put it into a valley and most of the walls are valley walls, so they are very strong,” he said.

“It makes this location very safe.”

The u-shaped valley will have gently-sloping dams at either end, constructed of sand from the tailings, Murphy said.

That is very different from the Mount Polley dam which consisted of a steeply-sloping ring dyke constructed of locally-sourced till material, he said.

“Most importantly, after treatment, water from the proposed KSM facility will be discharged on an annual basis, preventing the build-up of any water within the facility as occurred at Mount Polley where there was no treatment of water for discharge,” he said.

Zimmer, who emphasized that Alaskan groups are concerned about the effect of the mine on any rivers, whether Canadian or Alaskan, said one of the major worries is what happens over time.

“What happens after 250 years? What if the water treatment fails or doesn’t work as proposed — Seabridge has no contingency plans for this,” he said.

Williams said there should be no concerns after closure as, after the tailings are topped and revegetated, there will be minimal water flow.

During the six-and-a-half-year review process, Seabridge held numerous meetings with Alaskan groups and regulators, including a public meeting in Ketchikan, Murphy said.

There was also a detailed assessment by independent federal regulators so there was no need for a panel review — as requested by Alaskans — because it would duplicate work already done, Murphy said.

Neither would a referral to the International Joint Commission be the correct process, Murphy believes.

“In our opinion [the IJC] is a political dispute resolution process and we are continuing to support efforts of the B.C. and Alaska governments who are working on increasing cooperation between the two governments on transboundary projects and we encourage them to work towards a memorandum of understanding,” he said.

But Zimmer said most of the meetings were open only to agency and company officials and many questions remain — such as lack of funds to deal with major accidents or proof that Seabridge can treat water for selenium.

“The arrogance demonstrated by Seabridge’s blind faith in their engineering in the face of the forces of Mother Nature and time, is the same arrogance that resulted in the Titanic, Three Mile Island, Chernobyl and Mount Polley,” he said.

Wrangell, Alaska — A fishing boat chugs across the water in front of the patio at Wrangell’s Stikine Inn, temporarily disrupting dinner conversation as residents of the tiny Southeast Alaska town tuck into heaped plates of rockfish and chips.

At the next table, where a group of friends are celebrating an 80th birthday, the talk is all about the next day’s fishing plans. The new salmon smoker is working well, there were more than 40 crabs in the pots yesterday and everyone wants to be out on the water before 9 a.m. tomorrow because there are king salmon to be caught.

Commercial and sports fishing fill the freezers and wallets of Wrangell residents but, out of mind for many of them, behind the shield of the Coast Mountains, lurks a threat that could annihilate the area’s fishing and tourism-based economy.

As Bonnie Demerjian gazes over the spectacular scenery, with snow-capped mountains, tree-covered slopes and rounded islands, she cannot understand why the entire population of Wrangell — which grows to 3,400 in summer and shrinks by at least 1,000 in winter — is not up in arms about the aggressive mining push across the B.C. border.

It frustrates her that it has taken images of torrents of toxic sludge, rushing down the valley from the Mount Polley tailings dam failure, to grab Wrangell’s attention.

“Until then, it seemed so far away. There’s pretty much a resource extraction mentality here and there has been too much apathy,” said the author, former school teacher, commercial fisher and journalist, who has lived in Wrangell since 1977.

Miner Jay Bradley, who grew up in Wrangell and now lives in Arizona, agree that most people in Southeast Alaska’s small communities would rather ignore the problem.

“Joe Blow on the street is just trying to make his house payments and we don’t have politicians with balls enough to even try and ask Canadians to tighten up,” he said.

Demerjian, whose first book was “Roll On! Discovering the Wild Stikine River,” has been trying to raise awareness about Canadian activities in the upper part of the Stikine River for at least three years. But, despite the community’s reliance on the river, the warnings have been largely ignored in a fiercely independent part of the state where many pride themselves on a subsistence lifestyle based on fishing and moose hunting and few people want to be associated with groups seen as radical environmentalists.

“I really think it is too late now. Red Chris (mine) is already producing and it’s only a matter of time before the dam breaks. It’s the same engineers as Mount Polley. It’s not if, but when,” Demerjian said gloomily.

Red Chris, a copper and gold mine owned by Imperial Metals — the same company that owns Mount Polley — opened for business on the Canadian side of the border two days after the independent report into the Mount Polley disaster was released.

The report contained recommendations such as adopting modern mining technology and moving to dry stack tailings storage where possible, but those recommendations will not apply to Red Chris or the giant KSM project in the Unuk watershed, which were already through the environmental assessment process.

Imperial Metals plans to store tailings in Black Lake, behind a dam, and it is estimated that, over the life of the mine, there will be more than 300 million tonnes of mine waste, some of it acidic, that will require water treatment in perpetuity.

There’s a lack of confidence in B.C.’s ability to ensure safety because the Canadian rules are seen as lax, Bradley said.

“It’s like night and day. They are allowed to do so much more on that side of the border,” he said.

Demerjian finds it hard to imagine what would happen to the salmon runs if there was a dam failure.

“What happens if the river becomes polluted?” she asked.

“No one will touch our fish."

Those Wrangell residents who are becoming aware of potential transboundary mining problems are startled when shown a map, with a chain of dots showing proposed B.C mine sites, that Aaron Angerman, tribal administrator for the Tlingit-Haida based Wrangell Cooperative Association, has outside his office.

While about 10 are in the assessment process, others have not yet gone beyond being staked by ambitious would-be miners.

The Stikine provides food, recreation and jobs and any spill or leak of acid mine drainage upstream would be crippling to the community, said Angerman, who grew up in Wrangell.

“For thousands of years our people have been reliant on the river. We are the Stikine tribe. If anything happened it would be a killer for this place.”

Like other members of the United Tribal Transboundary Mining Work Group, Angerman wants to see the Boundary Waters Treaty enforced, better safety practices in B.C and Alaskans given an equal voice in decision-making on transboundary mines, although he worries about the impossibility of trying to stop a multi-billion industry that is supported by the B.C. government.

In the meantime, his main task is informing people about the risks.

“We need to get people together and show them what Mount Polley looks like and what the Williams Lake people are saying and tell them that this could be us if it goes badly,” he said.

“Anything that we can accomplish is better than just sitting here and waiting for a freight train to hit us.”

Wrangell and the neighbouring community of Petersburg, along with national and Alaskan native organizations and larger communities such as Juneau and Ketchikan have passed resolutions asking that the issue be passed to the International Joint Commission and that B.C. look at the cumulative impact of the mines in the Stikine, Taku and Unuk watersheds.

The  resolution sets out concerns with B.C.’s record and weakened environmental laws.

“The ongoing acid mine drainage from the Tulsequah Chief mine and the tailings dam failure at the Mount Polley mine demonstrate weaknesses in monitoring and enforcement,” says the preamble to the Petersburg resolution.

Meanwhile, Demerjian wonders what has happened to Canada’s environmental sensitivities.

“I used to think of Canadians as being much more environmentally aware and now, no one can say that,” she said.

Officials with the Cariboo Regional District declared a local state of emergency Wednesday after millions of cubic metres of contaminated tailings water from the Mount Polley mine flooded Hazeltine Creek early Tuesday morning, spilling into Quesnel Lake. Water drinking and water use bans have been issued for Quesnel Lake, Polley Lake, Hazeltine Creek, Cariboo Creek, and the Quesnel and Cariboo River systems, up to the Fraser River, according to the B.C. Ministry of Energy and Mines.

The breach, caused by the collapse of a berm supporting a lake of mining waste that spanned four square kilometres, released an estimated 10 million cubic metres of water and slurry that contains toxic processing wastes including arsenic and mercury into salmon spawning and drinking waters.

The tailings pond at Mount Polley mine, operated by Imperial Metals, was used to dispose of 84,000 kilograms of arsenic, 10,000 kg of cadmium, 38,000kg of lead and 562 kg of mercury in 2013, according to company data released to Environment Canada.

Imperial Metals mines both gold and copper on Mount Polley.

A video released by the Cariboo Regional Discrict shows the scope and extent of the Mount Polley Mine tailings breach.

“I apologize for what happened,” Imperial Metals president Brian Kynoch told a press conference yesterday. “If you asked me two weeks ago if this could have happened, I would have said it couldn’t.”

Kynoch said the company can only speculate on the cause of the tailings pond failure and said an investigation is needed.

He said the quality of the tailings is “close to drinking water quality,” adding “there’s almost everything in it but at low levels…No mercury, very low arsenic and very low other metals.”

A screen shot from Google Maps shows the approximate location of the breach, near Likely, B.C.

The provincial Ministry of Environment in B.C. said it issued repeated warning to Imperial Metals about the Mount Polley tailings pond, according to the CBC. Ministry spokesperson Kim Franklin to the CBC her office had issued five warnings in May alone, the most recent concerning wastewater height in the pond.

Franklin also said the company requested permits to discharge increasing amounts of wastewater from the mine, which led to an independent overview in 2009.

Brian Olding, an environmental consultant who carried out the assessment, said the company allowed pond levels to get too high. “It means the water is rising so you have to build the walls of the tailings lagoon higher as you go,” Olding told the CBC.

In his report Olding said the company would need to eliminate 1.4 million cubic metres of water on an annual basis to maintain stable levels in its tailings facility.

Gerald MacBurney, a former foreman at the mine, said he warned management at Mount Polley about concerns he had with the tailings enclosure. He said Imperial Metals added five times the amount of water to the tailings pond than was originally planned for after the company decided to expand its operations.

Bill Bennett, B.C. minister of energy and mines, said the spill is a “serious incident that should not have happened.”

Bennett, who is in the area, said the company has been fairly compliant and safe throughout the years.

“From the air it’s a true disaster. It looks like a combination of a serious avalanche, [mixed with] millions and millions of litres of water having gone down a fairly steep grade. It’s changed the creek bottom from about six feet wide to about 150 metres wide, so that gives you some idea of the force of all of this water when it went down.”

“It’s unprecedented in Canada for this to happen,” he said.
