Flaring at NOVA Chemicals Corunna is much higher than normal Wednesday.
Company spokesperson Meaghan Lawrence said it's a result of a unit upset at around 3:30 a.m.
She said it's unknown how long the elevated flaring will continue and the company apologizes for the noise and light disturbances.
Lawrence said they're actively working to return the facility to normal operating conditions as soon as possible and there are no other offsite impacts at this time.
