Report details equipment problems, flaring violations at LNG Canada
An emissions report LNG Canada filed to the B.C. Energy Regulator details operational issues at the plant in March as it continued to surpass the amount of gas it is allowed to burn off through flaring.
The document, obtained by University of Victoria air quality researcher Laura Minet under freedom of information proceedings, says a crack developed on the plant’s warm/wet flare tip on Feb. 18, followed by another five days later. Work to replace that component is set to begin in mid-June.
In the meantime, gas that would have gone through that flare tip is being diverted to a spare one, which the report said was the largest source of flaring by volume during March, at 16.7 million cubic metres. In non-routine scenarios, like this one, the authorized rate of discharge from the spare flare is “as required” without a specified limit, the LNG Canada permit says
“The rationale for not subjecting the non-routine flaring volumes to the permit is that non-routine is typically an emergency, and the regulator prefers the facility to flare rather than vent in those cases, for safety reasons,” said Minet.
