Regulators decided to look at six alternate routes for Enbridge Energy's proposed Sandpiper crude oil pipeline.
"...Thousands of property owners along the alternative routes face the prospect that their lands might be affected. Opposition to one of the reroute ideas, through the Detroit Lakes area, already is surfacing..."
What Is Line 3?

"Built in the 1960's, 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 standard, reduce future maintenance activities resulting in fewer disruptions to landowners and the environment, as well as 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. ."
2009 (May 21st) – Superior, Wisconsin – 155 barrels – An Enbridge pipeline pig sending trap leaked due to operator error, spilling about 6500 gallons of crude oil. 700 cubic yards of contaminated soil had to be removed.
2007 (November 13th) – Clearbrook Minnesota – Line 3. Enbridge discovered a leak on their 34-inch Line 3 at Mile Post 912. Later, the pipeline exploded during repairs, on November 27, causing the deaths of two employees. DOT officials said that two Enbridge workers died in a crude oil explosion as they worked to make repairs on the former Lakehead system pipeline. Enbridge was cited for failing to safely and adequately perform maintenance and repair activities, clear the designated work area from possible sources of ignition, and hire properly trained and qualified workers.
2007 (January 1st) – Superior, Wisconsin – 1,500 barrels / 50,000 US Gallons spilled onto farmland and into a drainage ditch. Cause: Incomplete fusion of a longitudinal weld at the pipe maker that failed as pressure cycle was established as the cause. The same pipeline was struck by construction crews on February 2, 2007, in Rusk County, Wisconsin, spilling 201,000 US gallons (760 m3) of crude, of which about 87,000 gallons were recovered. Some of the oil filled a hole more than 20 feet (6.1 m) deep and contaminated the local water table.
2002 (July 4th) – Cohasset, Minnesota – 6,000 barrels / 950 m3. Cause: Cracking caused by train shipping induced cracking of the pipe being delivered. The pipeline ruptured in a marsh in Itasca County. In an attempt to keep the oil from contaminating the Mississippi River, the Minnesota Department of Natural Resources set a controlled burn that lasted for 1 day and created a smoke plume about one mile (1.6 km) high and five miles (8 km) long.
1991 (March 2nd) – Grand Rapids, Minnesota – A Lakehead (now Enbridge) crude oil pipeline ruptured, spilling more than 40,500 barrels of crude oil into the Prairie River, of which 39,800 barrels were eventually recovered. About 4 million US gallons (15,000 m3) of oil had spilled from that pipeline from the early 1970s to 1991, per Minnesota records. A resident in the area noticed the smell of oil and alerted the local fire department. Approximately 300 people living in homes near the site were evacuated for safety, but were allowed to return to their homes later in the night.
