CALGARY, Alberta, Jan. 5 (UPI) -- Canadian pipeline company Enbridge announced plans to shut down parts of an oil pipeline in southern Michigan for maintenance work.
Enbridge said it was replacing "certain non-contiguous segments" of its Line 6B pipeline in Michigan. The work involves replacing 14 sections of the pipeline in Livingston and Oakland counties "in conjunction with Enbridge's aggressive pipeline integrity management program," the company said.
Line 6B is scheduled for closure in Livingston County Feb. 7 and in Oakland County on March 7. Outages are expected to last for a maximum of five days, Enbridge said in a statement.
Line 6B of the Enbridge-operated Lakehead oil pipeline system ruptured in southern Michigan in late July, spilling around 20,000 barrels of oil into area waterways. A 12-inch dent was found later on a section of the same pipeline running under the St. Clair River.
The U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration said in a restart plan for Line 6B that Enbridge needed to replace the damaged St. Clair leg within a year.
The company in late September received approval from U.S. regulators to restart the pipeline provided Enbridge addressed a long list of concerns along Line 6B.
