Greenpeace spokesmen Peter Louwe said that the action began at 7 a.m. PT and that two protesters had climbed onto the oil pumping mechanism. Fourteen others are on the scene with a large banner.
They have been joined by at least one elder of the Tsleil-Waututh First Nation, whose traditional territories span across the shores of the Burrard Inlet and who are now based on the shore opposite Kinder Morgan's shipping facility.
The Kinder Morgan facility is the west coast terminus of the Trans Mountain pipeline that carries Alberta bitumen from the Edmonton area, across southern British Columbia to port just east of Vancouver in Burrard Inlet, for shipment overseas.
The activists are protesting Kinder Morgan's plans to nearly triple the Trans Mountain pipeline's capacity from 300,000 barrels a day to 890,000.
As of 10:30 a.m. PT, several RCMP officers had arrived on scene, but said they had no immediate plans to take any action.
More to come.
