Shell officials continue to monitor a tank at the Corunna Refinery tank farm in St. Clair Township, Canada, that developed problems Sunday afternoon.

Employees making routine inspections noticed an odor around 4:30 p.m., and, upon further investigation, discovered oil on the top of the floating roof of the massive tank, said spokesman Randy Provencal.

Additional Chemical Valley Emergency Coordinating Organization (CVECO) foam equipment was requested and St. Clair firefighters responded with their special ladder truck with attached camera equipment that allows them to view the tank without having to put personnel near it.

“We continue to monitor the tank and apply suppressant foam which acts as odor mitigation,” Provencal said. “We recently conducted air monitoring right at the source at the tank and there were no VOC’s (volatile organic compounds) detected there, so that’s good news.”

Provencal said they are working on plans on how to remove the crude oil and water inside the tank.

“It’s a floating roof on this tank, so as a result it’s not uncommon for there to be water in the tank,” he said. “We need to be able to remove both the crude oil and the water and we’re working on plans right now to do that.”

They haven’t yet been able to determine just what occurred, nor is it know yet how much product is inside the tank.

There were no injuries and the Ministry of the Environment was notified.
