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.
As part of our maintenance program, Enbridge has gathered extensive integrity data on Line 3. The data has been analyzed, resulting in the need for a substantial number of integrity digs and repairs. Since 2008, Enbridge has safely operated and maintained Line 3 by implementing voluntary pressure restrictions. As a result of the integrity maintenance program, Enbridge concluded that replacement is the optimal alternative to the required ongoing and increasing maintenance activities.
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.
Enbridge’s Line 3 replacement is an integrity and maintenance driven project; it will reduce future maintenance activities and resulting disruptions to landowners and the environment, as well as restore the historical operating capabilities of Line 3.
