Suncor Energy Inc - Provides RMWB operations update

• The safe transport of Fort McMurray residents out of the region continues.
• There is no damage to any of the Suncor assets or operations in the Fort McMurray region and as an additional precaution, we have enhanced the fire mitigation and protection around our operating facilities.
• Suncor has, in a planned and controlled fashion, safely shut down operations at its base plant, MacKay River and Firebag in response to the third-party precautionary shut-in of key takeaway pipelines and limited availability of incoming diluent. Prior to the fire, Suncor was operating at reduced rates of approximately 300,000 bbls per day as it undertook a planned turnaround.
• The actions taken are expected to enable a safe and prompt return to full production. Planning for restart is well advanced.
• Syncrude continues to operate at reduced rates reflecting limited labour availability.

"I'm pleased we're able to continue assisting with the safe movement of thousands of people out of the region," said Steve Williams, Suncor president and chief executive officer. "We can now begin preparations for a safe return to operations."

Suncor will provide regular updates through Facebook and Twitter.
