Petroleum products are part of our everyday lives - from how we fuel our cars and heat our homes, to the clothes we wear, the household products we buy, and how our food is grown. But before those products materialize, crude oil must be refined into petroleum.
Line 3 is an existing 1,097-mile crude oil pipeline, originally installed in the 1960’s, that extends from Edmonton, Alberta to Superior, Wisconsin, and is an integral part of Enbridge’s Mainline System.
Safe and reliable operations are the foundation of Enbridge's business, and maintaining pipeline safety through the integrity management program is essential. As part of our routine maintenance program, Enbridge conducted an assessment of the Line 3 pipeline in 2013. The assessment identifies strategic and efficient means for maintaining system integrity, including additional in-line tool runs, investigatory digs or segment replacement. Enbridge further determined that a replacement of Line 3 was best to maintain system integrity while minimizing disruption to landowners and communities.
The Line 3 Replacement Program consists of 1,031 miles of 36-inch diameter pipeline that begins in Hardisty, Alberta and ends in Superior, Wisconsin. The Program is an approximate $7.5 billion private investment ($2.6 billion for the U.S. portion), making it one of North America’s largest infrastructure programs, which supports North American energy independence. The U.S. portion of the Line 3 Replacement Program (from Neche, North Dakota, through Minnesota, to Superior, Wisconsin) is referred to as the Line 3 Replacement Project.The U.S. portion includes includes about 13 miles in North Dakota, 337 miles in Minnesota, and 14 miles in Wisconsin.
The proposed 36-inch replacement pipeline will serve the same purpose as the existing Line 3, which is the transportation of crude oil from Canada to the Enbridge Clearbrook Terminal near Clearbrook, Minnesota and to Enbridge’s Superior Station and Terminal Facility near Superior, Wisconsin. The replacement pipeline is generally expected to serve the same markets, and transport the same product mix as the existing Line 3. The line is physically equipped to transport all grades of crude oil, and the type of crude oil transported in the future (as in the past) will be based on shipper demand. Upon replacement, the average annual capacity of Line 3 will be 760 kbpd,
Enbridge’s L3R Project is an integrity and maintenance driven project; it will reduce future maintenance activities resulting in fewer disruptions to landowners and the environment, as well as restore the historical operating capabilities of Line 3.
