Fraser River Pile and Dredge (GP) Inc. | Langley Outfall Maintenance Dredging
In December 2020, a project permit was issued to Fraser River Pile and Dredge (GP) Inc. (the Applicant) to undertake Maintenance Dredging around the Langley wastewater treatment plant outfall. The project is located in the Fraser River at 103201 – 201 Street, Langley, British Columbia on federal waters managed by the Vancouver Fraser Port Authority.
The project was approved subject to 30 permit conditions that the Applicant must meet to ensure the project does not result in significant adverse environmental effects.
The port authority issued a multi-year permit to cover ongoing maintenance dredging. Each dredging event is expected to take approximately three days and will occur during the least risk fish window for the Fraser River.
About the proposed project
Fraser River Pile and Dredge (GP) Inc. (the Applicant) on behalf of Metro Vancouver proposes to undertake maintenance dredging to remove accumulated sediments from the Langley wastewater treatment plant outfall pipe, located in the Fraser River at 103201 – 201 Street, Langley, BC. The outfall pipe is blocked by accumulated sediment and requires dredging to maintain facility operation. The proposed dredging work will be conducted by clamshell dredge from a barge, with support from an underwater dive team. Dredging of the accumulated sediment will take place in a footprint of approximately 1,800 square meters. The volume of sediment that will be removed will be less than 4,000 cubic meters, and sediment will be disposed of at sea under a valid Environment and Climate Change Disposal at Sea permit.
