Enbridge was founded in 1949 as the Interprovincial Pipe Line Company and built its first pipeline moving crude oil from Regina, Canada south across the border to Superior, Wisconsin. The company was renamed Enbridge in 1998, and in 2017 completed a merger with Spectra Energy, thereby creating the “largest energy infrastructure company in North America.”[23] Enbridge operates over 17,000 miles of crude oil and liquids pipelines – around half of which is located in the U.S. – and has a stake in more than 193,000 miles of natural gas and natural gas liquids (NGL) pipelines.

July 25, 2023 - 13th Anniversary
Kalamazoo River Spill

13th Anniversary of the disastrous day in July 2010 that Enbridge caused one of the largest inland oil spills in American history when its Line 6B pipeline burst near Marshall, Michigan. The failed pipeline gushed oil for 17 hours and dumped 1.2 million gallons of heavy tar sands oil into the Kalamazoo River watershed. It took four years and over $1.2 billion to clean it up to the extent possible. Line 6B was 41 years old when it failed; Line 5 is 69 years old and counting.
