Description of the Application
Suncor Energy Inc.

The proposed elevation change would allow the STP to store an additional 120 million cubic metres of fluid tailings. The STP is located in Townships 90 and 91, Ranges 8 and 9, West of the 4 Meridian, southeast of Suncor's Millennium Mine. No changes in the location or disturbance footprint of the STP are proposed. Currently, the STP is in operation and provides storage for fluid extraction tailings.
