What is Disposal at Sea?

Disposal at Sea (DAS) is a dredging activity which will provide necessary depth for the larger ships associated with the LNG Canada project at their wharf, with the clean material being safely disposed at sea. The work will continue this season until February 15.

Is Haisla Nation Council supportive of this?

Yes, LNG Canada has consulted extensively on this project with Haisla, and Haisla Nation Council staff are involved in the ongoing monitoring of the project.

What is the benefit of this activity?

Aside from the depth requirements for ships, this activity will significantly clean up the seabed at the head of the Douglas Channel. Decades of industrial activity has left certain areas contaminated. This project will gather and properly dispose of any toxic or contaminated material from the seabed.

Where does the contaminated material go?

Any contaminated material from the seabed will either be used safely for industrial and construction purposes or, if required, shipped away to be disposed of in specialized landfills.

Will this work affect the environment?

Any impacts to sea life are being mitigated and only clean dredge material is deposited at sea. The work is also being conducted in very precise areas to ensure limited impacts to the environment. Environment Canada is involved.

How are impacts being mitigated?

LNG Canada selected their disposal site out of five possible locations. Water turbidity (the amount of particulates in the water) is closely monitored and all activity is responsive to water quality changes and to marine life sightings around the work area.

Can I fish or crab in the area of this work?

Members are advised not to crab or fish in the area of this work until it is complete.
