St. Clair ethanol plant

The St. Clair Ethanol plant, Canada's largest ethanol plant, opened in 2006 and is operated by Suncor. Prior to 2009, the environmental data from the St. Clair ethanol plant was included in the Refining & Marketing Canadian operations. This historical data has been removed from the Refining & Marketing business unit and stated here for comparability purposes.
