As TC Energy's 670-km natural gas pipeline (dubbed Coastal GasLink) nears completion in British Columbia, Canada, the British Columbia's Environmental Assessment Office has fined the pipeline Canadian $346,000 - $256,810 for non-compliance with environmental regulations.

The inadequacies were identified during four multi-day inspections along the pipeline construction route in April and May 2022.

"The reporting error was due to an administrative contractor record discrepancy that was provided to the EAO between October 2022 and January 2023," Coastal GasLink said in a statement. "This was an unintentional and regrettable error."

Coastal GasLink will connect gas fields in northwestern British Columbia with the Shell-led LNG Canada project, which will be Canada's first liquefied natural gas project when it starts operating in the middle of this decade.

The fines are the latest in a series of financial penalties paid by the troubled project, totaling more than C$800,000.

Coastal GasLink is 94% finished and scheduled for mechanical completion late this year, Coastal GasLink said. It is expected to cost C$14.5 billion, more than double the initial estimate.
