Would tanker traffic increase if the proposed pipeline was built? Acoustic disturbance: Increased tanker traffic will cause acoustic disruption underwater, and cause marine animals to change their behaviour -- especially culturally important species such as whales and blackfish. For more information, see our page on the pipeline's impacts on whales.
How would Orcas be impacted by the proposed Kinder Morgan pipeline? Marine Mammals, including orca, are at risk in the event of an oil spill: Southern resident killer whales in British Columbia are considered endangered species, while northern whales are considered threatened but recovery plans in place are weak. Many marine mammals, including orca reside in or visit Burrard Inlet.
