Petroleum products are an essential part of our everyday lives. They fuel our cars, heat our homes, power industry, schools and hospitals, and are turned into hundreds of consumer goods, from clothing to cosmetics to cellphones. But before those products materialize, crude oil must be refined into petroleum.
Built in the 1960s, Line 3 is a 1,097-mile crude oil pipeline extending from Edmonton, Alberta to Superior, Wisconsin, and is an integral part of Enbridge's Mainline System. Enbridge is proposing to replace Line 3 to maintain our high safety standards, reduce future maintenance activities and create fewer disruptions to landowners and the environment, and restore the historical operating capabilities of Line 3. A new 36-inch diameter pipeline will replace the existing 34-inch diameter pipeline along most of the Line 3 route. In the U.S., the replacement pipeline will follow Enbridge's existing Line 3 route from Joliette, North Dakota to Clearbrook, Minnesota, and then will primarily follow existing pipeline and transmission routes from Clearbrook to Superior, Wisconsin.
Line 3 has been, and continues to be, an essential component of Enbridge’s pipeline transportation network to deliver the crude oil needed by refiners, and used by residents. The replacement of Line 3 will ensure that Enbridge can transport the crude oil required by refiners in Minnesota, neighboring states, Eastern Canada and the Gulf Coast. As with the existing Line 3, the Project will be operationally integrated as part of the Enbridge Mainline System and will continue to transport crude oil from Hardisty, Alberta, Canada to Superior, Wisconsin.
