It is all well and fine that this is the only known incident in 30 years. So are those noise-makers supposed to operate for the next 100 years or so. Is that the final solution? Is anything being done that will allow birds to ever be able to safely use those waters? Any pictures I saw of the site showed a barren shore-line, devoid of even one organic plant.
Does anybody up there even know that cat-tails do quite a nice job of cleaning up 'oil' (and probably a lot of other things as well). An even better plant is hemp, that plant was what was recommended for 'cleaning' the tailings from the 'old gold-mines' in the Yukon, so if it will work on heavy metals I'm quite sure it would work around the contamination (and that is just what it is) around Syncrude.
Hemp is also about the only viable solution for the DU in Iraq (and other places) but since it would probably take 40 years to accomplish that it will never be started, not for the old gold-mines, not for the tailing ponds at Syncrude, nor for DU anywhere. It is best that that plant be left in it 'devil' status and that is a purely profit driven agenda.
