VANCOUVER, Wash. (AP) — Protesters at the Port of Vancouver, Washington, are blocking a shipment of pipeline meant for the Trans Mountain Pipeline Expansion project.

KOIN reports that Tuesday morning at least five people climbed up and chained themselves on the dock where the shipment is to be loaded off of.

Other “kayaktivists” were in the surrounding water, rallying behind the climbers to stop this project they say “is jeopardizing a livable future for everyone on this planet.”

Local law enforcement and the Coast Guard were monitoring the situation.

The Trans Mountain Pipeline carries crude oil from the Alberta tar sands to the British Columbia coast for export. The expansion project would add a second parallel line that would nearly triple the system’s capacity.
