A unit upset Tuesday morning at Shell Corunna has resulted in higher than normal flaring.
The company's Bryant Bird says the upset happened at around 9:30am.
He says site personnel are working to limit disruptions to normal operations.
"You'll see some higher than normal flaring," says Bird. "Really wanted to let people know that the product itself is a very light hydrocarbon, primarily hydrogen, [the] byproduct is primarily water so as a result, little steam is required. There shouldn't be much noise and little impact to our neighbours."
Bird says the Ministry of Environment and Climate Change and neighbours downriver have been notified of the controlled flaring event, which is expected to last 12 to 24 hours.
