Maintenance Dredging - Lhoist North America of Canada Inc.

The proposed project 

Lhoist North America of Canada Inc. is proposing to conduct annual maintenance dredging of their barge loading berth located at 20303-102B Avenue, Langley, B.C. Dredging is required to maintain design depths of -6.10 metres Chart Datum. The dredge area is 100 x 30 m, and the maximum dredge volume will be 4,000 cubic metres per year for the next five years. Dredging would be performed using a clamshell dredge from a barge-mounted derrick with dredged material to be loaded to an adjacent flat scow. The proposed disposal is at a disposal at sea (DAS) site approved under a dredging contractor's multi-site disposal at sea permit. Work is proposed to take place within the Fisheries and Oceans Canada (DFO) least risk window for the project area.  

Sediment sampling and testing was conducted in December 2021. The material consisted of silty loam and sandy loam and exceeded DAS criteria for Arsenic and Copper. Subsequent sediment toxicity testing (Tier 2 testing) was completed in January 2022 and passed DAS criteria.
