The critical bit...
The resulting so-called dilbit product is about 30% diluents and 70%
bitumen. We do know a lot more about dilbit than we used to. And we did a
lot of that learning through the 2010 Enbridge dilbit spill in the
Kalamazoo River in Michigan. We know it both floats and sinks; that it
is far harder and far more expensive to clean-up than unprocessed
conventional crude. The Kalamazoo spill is still not cleaned up.
Meanwhile
a debate rages about whether dilbit is more likely to cause pipeline
failure. Cornell University found that between 2007 and 2010 pipelines
carrying dilbit had a spill-rate three times higher than pipelines
carrying conventional crude. Oil sands products have a higher sulfur and
a higher acidic content than conventional crude and those properties
could explain its increased corrosive nature.
This finding led to
the Department of Natural Resources to commissioning a study by a group
called Alberta Innovates Technology Futures (ATIF). That study compared
dilbit and conventional crudes and concluded the types of corrosive
compounds between the two products were comparable. So we have labwork
versus the real life rate of spills in US pipelines. At the moment,
despite what Harper’s Cabinet ministers claim, the science on the
corrosive nature of dilbit is not settled.
Meanwhile, if local
residents along the Number 9 pipeline wish to speak before the NEB
hearings, or even submit a letter, they are required to fill out a
10-page form, and are also encouraged to submit references and a resume!
This is an NEB effort to meet the new requirements imposed by the
horrific overhaul of the Canadian Environmental Assessment Act that took
place last year in the Omnibus Budget Bill (C-38).
Unlike the
previous CEAA, which was premised on a fundamental commitment to rights
of public participation, the Harperized CEAA restricts access to only
those ‘directly affected’. The NEB has made this restriction even worse
by demanding that any citizens who want to make comments, fill out the
forms and apply within a two-week period—which will close before this
article will be in print.
