Enbridge Line 2 Oil Pipeline, which is composed of Enbridge Line 2A and 2B, is an oil pipeline in the Enbridge Pipeline System. It transports oil from western Canada to Enbirdge's Superior Terminal in Wisconsin, United States.[1]


The pipeline originates in Edmonton, Alberta, and terminates in Superior, Wisconsin. The Enbridge Line 2 Oil Pipeline runs parallel to the Enbridge Line 1 Oil Pipeline, Enbridge Line 3 Oil Pipeline, and the Enbridge Line 4 Oil Pipeline.[1]

Line 2 was placed into service in 1957.[1] It's comprised of two sections, 2A and 2B. Section 2A is a 600-mile section running from Enbridge’s Edmonton Terminal near Edmonton, Alberta, terminating at Enbridge’s Cromer Terminal near Cromer, Manitoba. Section 2B is a 502-mile section running from Enbridge’s Cromer Terminal near Cromer, Manitoba and terminating at Enbridge’s Superior Terminal near Superior, Wisconsin.[3]


In January 2010, Enbridge shut down Line 2B after discovering a leak in Pembina County, North Dakota.[4] In total, approximately 3,748 barrels of synthetic crude oil was released at milepost 774.18.[5]

In July 2010, Enbridge discovered a leaking flange on Line 2 at the North Cass Lake, Minnesota, Station, with as much as 1,500 barrels of oil released.[5]

In September 2015, Enbridge spilled 29,000 gallons of water when test equipment malfunctioned at a pump station near Floodwood, North Dakota as part of a hydrostatic dye testing.[6][7]
