Suncor's Sarnia refinery prepares for start-up of new diesel desulphurization unit

Sarnia, Ontario (June 21, 2006) — Suncor Energy Products Inc. announced today that the new diesel desulphurization unit at its Sarnia refinery is ready for production.

During the start-up process, increased flaring and noise may be observed. Procedures are in place to ensure a safe start up and eliminate offsite impacts.

The new diesel desulphurization unit is the first phase of a two part expansion and upgrade of the refinery. The second phase of this $800 million project is expected to increase the refinery's capacity to process synthetic crude oil from Suncor's oil sands operations in Fort McMurray, Alberta. This second, and final phase of the project is scheduled for completion in 2007.

Suncor is committed to continuously improving its environmental, health and safety performance and to maintaining the quality of life in the Sarnia-Lambton region.
