Suncor Energy (U.S.A.) Inc. ramps up production with completion of maintenance shutdown

Denver, Colorado (April 17, 2006) - Suncor Energy (U.S.A.) Inc. announced today it has completed a planned maintenance shutdown to a portion of its Commerce City refining operations.

The plant is now ramping up to its production capacity of 90,000 barrels of oil per day. During the shutdown, which began February 3, 2006, refinery rates were reduced to about 34,000 barrels per day.

"While the maintenance turnaround lasted longer than initially planned, our key goal was to complete the job safely, thoroughly and with as little impact to our community neighbors as possible," said Nancy Thonen, refinery general manager. "We accomplished that goal."

"This was the largest and most complex shutdown in the refinery's history. Approximately 400 employees and 1,800 contractors worked over the past two months to help provide more reliable production and improve environmental performance at our refining operations."

During the maintenance shutdown, the company also began commissioning some of the new units for its Odyssey project. The new units are expected to allow Suncor to process 10,000 to 15,000 barrels per day of oil sands sour crude and meet environmental regulations that limit sulfur levels in on-road diesel fuel. Suncor expects the remaining units to come online during the second quarter of 2006.

During the maintenance shutdown equipment was also installed to reduce refinery emissions.

While modifications will allow the refining facilities to process more crude oil feedstock from the company's Canadian operations, Suncor remains a major purchaser of Rocky Mountain crude oil, last year averaging nearly 65,000 barrels of local crude oil per day.

Through the course of the shutdown, Suncor made arrangements to ensure continued supply of petroleum products to its customers. Colorado's retail fuel prices remained below the national average during the shutdown period, reflecting minimal impacts to retail fuel supplies in the state.

The 90,000 barrel per day refining facility is located in Commerce City, about six miles northeast of downtown Denver. It supplies about 35 percent of Colorado's gasoline and diesel fuel demand and is a major supplier of jet fuel to the Denver International Airport. It is also the largest supplier of paving-grade asphalt in Colorado.
