FEATURE: Alberta’s oil-sands
More than a million barrels of crude flow out of Alberta’s oil-sands plants every day.
Environmentally, it’s a disaster zone. There’s no turning off the tap, but improvements
in five areas could limit the staggering scale of the ecological damage.

“HARD TO BELIEVE, HEY?” says Scott Kinnee, the helicopter pilot flying me over the Athabasca oil sands north of
Fort McMurray, Alta. “You don’t really get a sense of the scale
of things unless you come up top.” Up top being 500 metres
above ground level, high enough to see 70 to 80 kilometres
in any direction; that is, until the sky closes over as we near
the dozens upon dozens of emissions towers and flare stacks
of the Suncor, Syncrude and Albian Sands plants. The
limpid winter sunshine we’d had at the airport hangar 30
kilometres to the south is gone, and the sun is now a dull
white bulb wobbling unsteadily behind a motionless sooty
haze. “Yeah,” says Kinnee, nodding as I remark upon the
sun’s enervation. “These plants are so huge, they basically
create their own weather system.”
|‘There are five major things that the oil sands companies
need to do if they really truly do care about the environment
and the amazing thing is that all five are achievable, not all
that expensive, and all use already existing technology.’
1 Carbon capture and storage
2 Dry tailings instead of wet
3 Reducing the overall water usage of the plants
4 Clamping down on the level of acidifying emissions
5 Establishing large areas of boreal forest that are off limits
The beauty of the boreal forest that surrounds Fort
McMurray and covers most of northern Alberta lies in its
magnitude, but once you arrive at oil-sands central, what you
see is a landscape erased, a terrain stretching in a radius of
many hundreds of square kilometres that is not so much negatively impacted as forcibly stripped bare and excavated.
Dominating this landscape are half a dozen giant extraction
and refining plants with their stacks and smoke and fire, disorientingly wide and deep mines, and tailings ponds held in check by some of the world’s largest dams. As a panoramic vision, it’s all rather heartbreaking but, if one is forced to be honest, also awe-inspiring, such is the energy and the damage produced by human ambition.
Yet despite how important, and how environmentally
divisive, the oil sands have become in today’s politically
charged energy domain, the early and even fairly recent
days of this resource were decidedly humble. In fact,
although it’s been a century or so since people first began trying to exploit the resource, it wasn’t until the mid-1990s that the Athabasca oil sands were launched on today’s bitumen
mega-arc, bitumen being the thick, tarlike hydrocarbon
extracted from the sands and refined into synthetic crude oil.
Predictions vary slightly, but production is expected to at least quadruple to four or five
million barrels of refined oil a day by 2020. From the start of the major expansions that
kicked off in 1996 to the conclusion of current planned construction in 2011, close to $100
billion will be spent by industry on the Alberta oil sands. All of this is staggering given
that in the early 1990s, not a single dollar of new investment was planned for the region
and that oil was selling for less than $20 a barrel. As this issue went to press, it was
going for $119 a barrel.
But in the early 1990s, Eric Newell, the former CEO of Syncrude and now Chancellor of the
University of Alberta, saw a different future for the oil sands. It was Newell who spearheaded
the formation of the National Oil Sands Task Force in 1995, which issued a report that year
calling for a new vision and scope in exploiting the sands. Newell and his task force made
the case, in Edmonton, Ottawa and Washington, D.C., that it was a resource in which it was
worth investing. “We pulled together a vision of what we thought was possible,” says Newell. “And
that was to triple production in 25 years and invest $21 billion to $25 billion.” He stops
and chuckles. “I’d stand up and say that, and a lot of people thought I was smoking something
funny. We were a bit off ! It took only eight years to triple production, and the industry
spent $30 billion. And now another $70 billion of investment is on the books, with production
projected for 10 times what it was then. None of us saw that happening, that’s for sure.”

would anyone care to comment on the environmental impact of the cities of the world? let's be honest. their combined areas would be multiples of hundreds of times the oil sands. challenge point - when are the lands that they are constructed on going to be returned to nature? the land under Tokyo and New York and London and Toronto are pristine, or has that land permanently been lost to nature?
In fairness a comparison to the coal mining by stripping the top off mountains. Comparison of the benefits and differences is an eye opener.
A lot of these comments are very naive. A law that requires the land to be returned to its original state is laughable. This area will take a long time to recover, if ever. Humans can't simply recreate nature as it once was. The process that achieved the ecosystems that were once where the oil sands were were complex and multifaceted, and as we can see with logging operations that "re-forest" clear cuts, what you end up with is a monoculture. The effects on the watershed are potentially disastrous if even a small percentage of the tailings reach the water table or the Athabasca River. The fact is that if we contaminate our water and soils and can no longer eat and drink, we won't be needing oil. Let's get our priorities sorted out and fund research in wind, tidal and solar power that, although not without their flaws, have less of an impact on the resources we truly cannot live without.
@Rod (comment 9/25) Please realize that satelite images on google maps are often dated years ago. They're NOT a tool to see the current world around you.
Saw this area on my way into Calgary yesterday from 12 km height and was impressed by the size of the area affected.
nature reclaims the land after they are done and tailings ponds are not going to be there in a couple of years there will be no need. 90 percent of water is recycled. This is new territory for tech we will be better but it takes time stop crying about things that you have no solution for.other countrys population is so bad you could not even grow a flower they have more people in a couple miles then we have in canada as a whole and do they care about the fact that breathing may not be an option in a couple of years NO. all they want is us to pay and scrifice everything so they can get it cheap or rip the idea off like china does now. That is what this is about makeing canada and the united states the lamb to the slauther.
I've used some common online resources to learn more about the oil sands. Sifting out the wide variations of estimates, I see that the costs in extracting bitumen is directly related to the energy used in the various technologies used to extract the oil.
So the more energy efficient the technology used, the higher the profits for Big Oil, and a lower the carbon footprint as a result. As the industry is really young and the technology relatively new, I see significant incentive for oil producers to continually develops cleaner, less costly (in terms of energy consumed) technology.
I'm not implying that this kind of mining is not polluting. It is. But these areas, by law, have to be returned to their original stat. For this more innovation has reduced the time in those toxic ponds to be cleaned up from years to weeks.
Although strip mining is not pretty and is a blight on the countryside, 90% of the oil sands cannot reached this way. Its to deep. Again there seems to be new, more efficient and less polluting technologies being developed.
An interesting quirk, one of the technologies being research to pull out the oil has resulted in the creation of equipment currently being used to clean up oil spills. This has been commercialized before its intend purpose has yet to be accomplished.
I don't see the apocalypse in this industry. I think over the long haul it will deliver cleaner energy overall. And I see corporations actually wanting to be green because of the higher profits associated with being green. I can't say I'm right — this is what I determined by actually looking up what the oil sands are and how oil is being produced.
I haven't read the entire article yet, but just before arriving on this page I was on Google Maps to see how these pit mines looked. Having visually looked at the size and scope to the actual mines, I found that the author's claim of "a landscape erased, a terrain stretching in a radius of many hundreds of square kilometres that is not so much negatively impacted as forcibly stripped bare and excavated" is just not true. See for yourself.
Those 20,000 jobs will be what is needed when it comes to clean up time. These guys just won't let it go. It's a very bad idea to ship this toxic waste anywhere. It's time to invest in clean, sustainable, renewable energies now. Make that pipeline food grade and we can send our precious melting glacier water directly to where it's most needed - the midwest. That's what they're really going to need. I really find it offensive that they use the name of our beloved "transcanada" trail. If this is not trickery from our government and big oil, I don't know what is.
What these people are forgetting is that eventually we will run out and then what?
Oil, gas, coal and nuclear power are not the means to sustain our planet.
Research and technology for cleaner energy alternatives must be looked at.
Canadians and the American people need to unite and make a stand, to stop oil production and further exploration. It is wreaking havoc in our oceans and our land. And all for the greed of $$$$.
