Background

Line 2 was placed into service in 1957. 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.

Accidents

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

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.

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.
