Odour potential from Suncor Energy's oil sands operation

Calgary, Alberta (July 10, 2006) — Suncor is informing the public of the potential for odours in the Wood Buffalo region.  Operational issues, compounded by isolated power outages caused by lightening strikes over the past week, have resulted in increased flaring and release of diluent (a light oil product) to Suncor's tailings ponds.

The extent of the odours will depend on atmospheric conditions, such as wind direction and velocity, and air temperature. Suncor has implemented 24-hour air monitoring in the area, including Fort McKay and Fort McMurray. Suncor's oil sands operations are expected to be back to normal early this week.

There are no health impacts expected from these odors. Alberta Environment and local stakeholders have been informed. Concerns about odours may be directed to the Alberta Environment Hotline at 1-800-222-6514.
