Our Rocky Mountain Business Unit consists of various interests in pipelines that transport crude oil produced in Alberta, Canada and the U.S. Rocky Mountain region, to refineries in Montana, Wyoming, Colorado and Utah. We also have refined products pipeline and terminals in the U.S. Rocky Mountain region. We deliver to these refineries directly through our pipelines or indirectly through connections with third-party pipelines. Our Rocky Mountain Business Unit is headquartered in Denver, Colorado with an operations and marketing office in Calgary, Alberta. We currently have five field offices in Wyoming and three in Alberta, Canada. Our Rocky Mountain Business Unit is comprised of the following assets, which form and integrated pipeline network.
Canada: Rangeland Pipeline System The Rangeland system includes the Rangeland pipeline and Mid-Alberta Pipeline ("MAPL pipeline"). The MAPL pipeline is a 138-mile proprietary pipeline with a throughput capacity of approximately 50,000 bpd if transporting light crude oil. The MAPL pipeline originates in Edmonton, Alberta and terminates in Sundre, Alberta where it connects to the Rangeland pipeline. The Rangeland pipeline is a proprietary pipeline system that consists of approximately 800 miles of gathering and trunk pipelines and is capable of transporting crude oil, condensate, and butane either north to Edmonton, Alberta via third-party pipeline connections or south to the U.S./Canadian border near Cutbank, Montana where it connects to the Western Corridor system. The trunk pipeline from Sundre, Alberta to the U.S./Canadian border consists of approximately 250 miles of trunk pipelines and has a current throughput capacity of 85,000 bpd if transporting light crude oil. The trunk system from Sundre, Alberta north to Rimbey, Alberta is a bi-directional system that consists of three parallel trunk pipelines: a 56-mile pipeline for low sulfur crude oil, a 63-mile pipeline for high sulfur crude oil, and a 56-mile pipeline for condensate and butane. U.S.: Western Corridor System The Western Corridor system is an interstate and intrastate common carrier crude oil pipeline system that consists of 1,012 miles of pipelines extending from dual origination points at the U.S./Canadian border near Cutbank, Montana, where it receives deliveries from the Rangeland pipeline, and at Cutbank, Montana, where it receives deliveries from Cenex pipeline, and terminating at Guernsey, Wyoming with connections in Wyoming to Frontier pipeline, Suncor pipeline, Platte pipeline and our Salt Lake City Core system. The Western Corridor system consists of three contiguous trunk pipelines: Glacier pipeline, Beartooth pipeline and Big Horn pipeline. We own various undivided interests in each of these three pipelines, which give us rights to a specified portion of each pipeline’s throughput capacity. Glacier and Beartooth pipelines provide us with approximately 25,000 bpd of throughput capacity from the U.S./Canadian border to Elk Basin, Wyoming. Big Horn pipeline provides us with approximately 33,900 bpd of throughput capacity from Elk Basin, Wyoming to Guernsey, Wyoming. We operate the Beartooth and Big Horn pipelines. Conoco Pipe Line Company owns the remaining undivided interests in each pipeline and operates Glacier pipeline. We also own various undivided interests in 22 storage tanks that provide us with a total of approximately 1.3 million barrels of storage capacity. Salt Lake City Core System The Salt Lake City Core system is an interstate and intrastate common carrier crude oil pipeline system that consists of 955 miles of trunk pipelines with a combined throughput capacity of approximately 114,000 bpd to Salt Lake City, 209 miles of gathering pipelines, and 32 storage tanks with a total of approximately 1.5 million barrels of storage capacity. This system originates in Ft. Laramie, Wyoming, receives deliveries from the Western Corridor system at Guernsey, Wyoming, and extends west to Wamsutter, Wyoming, where it divides, with a northern segment continuing west, eventually delivering to Salt Lake City, and a southern segment extending south to Rangely, Colorado, where it delivers to ChevronTexaco pipeline that serves refineries in Salt Lake City. During 2004, of the 114,000 bpd delivery capacity into Salt Lake City, the northern segment delivered approximately 40,100 bpd and the southern segment delivered approximately 18,000 bpd. Also during 2004, 42,500 bpd were transported from Frontier/Evanston Station, Utah to Kimball Junction, Utah, 7,300 bpd were transported from Reno to Casper, Wyoming and 3,000 bpd from Reno to Guernsey, Wyoming. We operate and own 100% of the Salt Lake City Core system. Frontier Pipeline Frontier pipeline is an interstate common carrier crude oil pipeline system that consists of a 289-mile trunk pipeline with a throughput capacity of approximately 62,200 bpd and three storage tanks with a total of approximately 274,000 barrels of storage capacity. Frontier pipeline originates in Casper, Wyoming, a hub for the distribution of crude oil produced in Canada and the U.S. Rocky Mountain region, and receives deliveries from the Western Corridor system. Frontier pipeline also receives Canadian crude oil, including Canadian synthetic crude, via connections with Express pipeline and other connecting carriers in Casper, Wyoming. Frontier pipeline delivers crude oil into the Salt Lake City Core system for ultimate delivery into Salt Lake City. We operate Frontier pipeline and own a 22.22% partnership interest in Frontier Pipeline Company, a general partnership that owns Frontier pipeline. Enbridge, Inc. owns the remaining partnership interest in Frontier Pipeline Company. Rocky Mountain Products Pipeline The Rocky Mountain Products pipeline is a common carrier products system that consists of 550 miles of refined products pipeline extending from Casper, Wyoming east to Rapid City, South Dakota and south to Colorado Springs, Colorado. The Rocky Mountain Products pipeline system includes products terminals at Rapid City, South Dakota, Cheyenne, Wyoming, and Denver and Colorado Springs, Colorado with a combined storage capacity of approximately 1.7 million barrels.
