A report by the City of Vancouver says Kinder Morgan's Trans Mountain pipeline pitch falls short on details.
The report says the application to the National Energy Board is incomplete and the review process inadequate.
Among the gaps, it says Vancouver Coastal Health can't fully assess Kinder Morgan's claims that there are minimal health risks because the company hasn't provided assessment reports.
It also says that the company's worst-case spill scenarios are not realistic, because they assume calm waters and no complications.
And like Northern Gateway, the Trans Mountain application suggests the diluted bitumen that will flow through the pipes will float in the event of a spill — which is not what Environment Canada studies have found.
The Trans Mountain pipeline linking the Alberta oil sands to Port Metro Vancouver will nearly triple the capacity of the line to almost 900,000 barrels a day.
