Suncor Energy receives Emerald Challenge Award

CALGARY, ALBERTA--(Marketwire - June 16, 2011) - Suncor Energy reported today that its TROTM tailings management process has won the 2011 Emerald Challenge Award. The award was presented by the Alberta Emerald Foundation during a ceremony held at the Citadel Theatre in Edmonton last night.

This year's Emerald Challenge Award, themed Alberta's Oil Sands, recognized an individual/group/business or government that has demonstrated a significant and ongoing commitment to environmental excellence and leadership in activities related to Oil Sands development in Alberta.

"We are truly honored to be recognized for our commitment to sustainable development," said Shelley Powell, vice president, Extraction Operations. "The TROTM process is a significant milestone on our sustainability journey and a tremendous source of pride for all of us here at Suncor."

Suncor's new approach for managing tailings, TROTM, was developed at its oil sands mining operations near Fort McMurray. The process, which received regulatory approval in June 2010, is expected to result in significant improvement in the speed of oil sands tailings reclamation. Suncor plans to invest more than $1 billion to implement the technology across its existing mining operations. Implementation towards full commercial scale operations is well under way.

Suncor and six other oil sands companies announced plans in December 2010 to work together in a unified effort to advance tailings management. Suncor intends to share details specific to its TROTM process with industry competitors so the environmental benefits of the innovation can be maximized.

Tailings are a mixture of fine clay, sands, water and residual bitumen produced through the oil sands extraction process. As tailings settle, a portion will eventually form mature fine tailings (MFT), a substance that has historically taken many decades to firm up sufficiently for reclamation. During the TROTM process, MFT is mixed with a polymer flocculent and then deposited in thin layers over sand beaches with shallow slopes. This drying process occurs over a matter of weeks, allowing more rapid reclamation activities to occur. The resulting product is a dry material that can be reclaimed in place or moved to another location for contouring and replanting with native vegetation.

Emerald Awards are bestowed annually to recognize and reward environmental initiatives undertaken in Alberta. Nominations are received in 10 established categories and evaluated by a panel of knowledgeable judges with cross-sector experience.
