Regina, SK — Investigators say a fire at the Co-op Refinery complex in Regina in May 2012 was caused by the failure of a mechanical crude oil pump. The pump then overheated and ignited the oil.
A temporary evacuation was ordered as black clouds of smoke billowed into the sky, but there was no explosion or injuries. Damage was contained to the pump house and is estimated at $5 million.
Investigators are still working on a report into a more serious fire in October 2011. An explosion in a unit used for processing diesel injured 10 people.
