Gas odour in Lower Mainland communities

Jan 17, 2024

SURREY, B.C.—January 17, 2024: On January 16, during a controlled release of gas at the FortisBC Interconnect Station in Ladner, we identified a minor leak, which was brought under control by 2pm the same day and repairs are underway.

The leak contained a high concentration of odorant (mercaptan) which is added to gas so that in the unlikely event of a leak it can be detected. Mercaptan is derived from naturally occurring compounds like hydrogen sulphide, which has a strong smell even in very low concentrations. It is not hazardous to inhale with the quantity released in the atmosphere.

The release of gas with a high concentration of mercaptan was not anticipated and, due to the strong smell, it has been detected by residents in several communities, including Ladner, Delta, Richmond and Vancouver. We apologize for the inconvenience this may cause residents and commuters in the area. We realize the odor is very strong but it is expected to dissipate.
