The booms containing spilled diesel fuel from a sunken tug 20 kilometres west of Bella Bella have failed in rough weather conditions.
A spokeswoman from Kirby Offshore Marine, which owns the tug, says crews are now working to reposition and replace the damaged booms as Gale winds and three-metre waves continue to batter the remote central coast.
The spokeswoman says while it is unclear how much fuel has spread into the open water, no oiled wildlife have been detected or captured since the rough weather began Friday.
But Heiltsuk Chief Marilyn Slett says her community is in shock of the incident and is questioning why more seaworthy booms weren't installed.
