Standing on a beach, the sand seems infinite but it’s being mined at an alarming rate to make concrete. Standing on the edge of an open pit sand mine used for fracking is hazardous and the pit is an ugly scar on the earth.
Sand is necessary for fracking. Once the shale deposits are fractured under high pressure, sand holds the pores open to allow oil or natural gas to flow.
Fracking operations have been suspended as cheap oil floods the market. But fracking will be back and so will the need for frac sand. When that happens, the B.C. Liberals will once again be flogging international markets with our natural gas under the pretence that it’s a clean fuel.
As it is, B.C.’s frac sand must be brought in from other provinces at a cost of $250 to $300 a tonne. Since single fracked well can use 10,000 tonnes, it’s obvious that oil and gas companies would like to have frac sand closer to home.
Not any sand will do; not what you’d find on a beach says Sean Cockerham of McClatchy News:
“Rounded quartz sand is needed because it’s strong enough to handle the pressure and depths involved in fracking. Beach sand is too angular and full of impurities.”
Descriptions for frac sand take on the connoisseurs’ appreciation of the soil for fine wine: the terroir of a particular region’s climate and soils that affect the taste of wine. The “Northern White” sand of Wisconsin is excellent for fracking. The hickory, or brown, sand of Central Texas is less desirable but has the benefit of being close to the home of the best oil and gas fields in the U.S.
Unlike the making of fine wine, the landscape is destroyed in the extraction of fine frac sand. Not only have that, but the piles of sand present a health hazard that’s worsened as a result of the slowdown in fracking says Ryan Schuessler for Aljazeera. Victoria Trinko lives one-half kilometer away from one of these drifting piles of sand.
“’That particular mine started in July 2011,’ Trinko, 69, said. ‘By April of the next year, I had developed a raspy voice. I was wheezing. Sore throat.’ She said her doctor later diagnosed her with asthma resulting from her environment. Her cows have started coughing, too, she said.”
What’s blowing in the wind is c, released into the air during frac sand mining. The mining company is supposed to keep the sand piles damp to keep it from blowing away but with the slowdown, maintenance is not profitable. Silica is a carcinogen and can cause silicosis, an incurable lung disease that can lead to death.
Stikine Energy Corp. of Vancouver thinks it’s found a solution to B.C.’s frac sand problem. Stikine president Scott Broughton says his company has discovered very promising deposits, large enough to support open pit mining. Despite the slowdown, the deposits 90 kilometres north of Prince George are still listed in B.C.’s major project website, waiting to be mined.
The dangers of frac sand should be another nail in the coffin of fracking but once the price of oil soars, watch for a resurrection.
