Enbridge Energy’s Line 5 oil and gas pipeline has been returned to service after being shut down over the weekend due to bad weather in the Straits of Mackinac. The company restarted the flow of oil and natural gas liquids on Monday afternoon. A company spokesman says “We continue to monitor the weather conditions in the Straits. Enbridge is committed to protecting the waters of the Great Lakes while ensuring families, manufacturers and other businesses safely receive the energy transported through Line 5.” The company is using an underwater remote-operated vehicle to inspect damage to Line 5. The Coast Guard reports that the pipe was dented by a ship anchor.
