PORT HURON, Mich., March 11 (UPI) -- Canadian pipeline operator Enbridge said it was preparing to install valves on a replacement pipeline under the St. Clair River in Michigan.
Crews from Enbridge pulled a 3,450-foot pipeline through a tunnel under the St. Clair River from Canada to the Michigan side. Inspectors from the company said there were no complications during the procedure and engineers were preparing to install valves on both sides of the line, The Times Herald newspaper in Port Huron, Mich., reports.
U.S. Rep. Candice Miller, R-Mich., whose district lies near the river, in August raised concerns about a 12-inch dent in a section of the Lakehead system pipeline that runs under the St. Clair River. Enbridge executives downplayed the risk at the time.
Line 6B of the Enbridge-operated Lakehead oil pipeline system ruptured in southern Michigan in July, spilling around 20,000 barrels of oil into area waterways.
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.
