The differential has only recently reached these marks. Because of how oil is bought and sold, pre-existing futures would likely maintain activity. If the differential continues to grow or remains at this level for an extended period then the impacts will begin to be felt.
But what was going to magically fix the differential other than the pipeline reversals/expansions?
That's like saying I would support the bombing of the US in order to reduce overall hydrocarbon consumption. This isn't a very constructive claim to have made.
It's not the percentages I'm worried about. It is the fact that they are comparing the amount of disturbed land (with active mining/tailings/etc...) to the amount of reclaimation certified land when they should be comparing the amount of land that is no longer in use and is being reclaimed to the amount of land having been certified. The amount of rec. certified land is still quite small as reclamation standards require that the areas being reclaimed need to be monitored for 15+ years before a certificate can be issued. Currently, there are about 4800 hectares of reclaimed land that are being monitored.
As I've mentioned above, 15 or more years of monitoring are required before the certificate can be issued. Pond 1 had been undergoing reclamation for quite sometime. As it was the original tailings pond used when operations began in the late 60's, there was a fair amount of accountability placed on Suncor to assure that the area was completely back to "equivalent land capability". This is a fairly comprehensive and onerous set of standards to meet so reclamation certificates are not a dime a dozen.
There currently is no legislation that states a specific timeframe as operations may sometimes reuse pre-existing sites that have been inactive for a period of time. This is an attempt to reduce footprint.
