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.
Enbridge has been safely and reliably transporting crude oil to U.S. refineries through its pipelines for decades. Line 3, built in 1968, is part of Enbridge’s Lakehead System. Line 3 is a 34-inch diameter, 1,031-mile pipeline from Edmonton, Alberta to Superior, Wisconsin and currently operates below its original capacity due to pressure restrictions.
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.
Enbridge is proposing to replace Line 3 to maintain our high safety standard, reduce future maintenance activities and disruptions to landowners, as well as to restore delivery capacity for reliable and efficient supplies of North American crude oil.
A new 36-inch pipeline will replace the existing 34-inch pipeline along most of the Line 3 route from Neche, ND to Superior, WI. Segments of Line 3 from the Canadian border to Neche, ND and near the Minnesota/Wisconsin border to the Superior terminal are being replaced under separate segment replacement projects.
After the replacement pipeline is built, the existing Line 3 pipeline will be deactivated according to federal regulations.
Safety is our first priority in all aspects of a project, from the current planning phase, through construction, operation, and maintenance. Our goal is zero incidents and we will maintain the highest safety standards and industry practices to ensure the continued safety of all our pipelines and facilities.
