Environmental groups in Indiana are pressing regulators to require Enbridge Energy to put leak detection sensors along a pipeline the company plans to install, according to the Associated Press. The groups also want independent monitors hired to oversee construction.
The groups, including the Hoosier chapter of the Sierra Club, say the requirements are necessary given the company’s history of oil spills. In 2010, an Enbridge pipeline ruptured in southwestern Michigan, sending more than 800,000 gallons of crude oil into the Kalamazoo River. The company also paid fines to Wisconsin in 2009 for violating state permits meant to protect water quality.
The new pipeline is planned to replace 286 miles of pipe that runs from Griffith, Ind. to Sarnia, Ontario. Michigan has approved permits for 160 miles of pipeline set to run through its territory, with about a third to run near Lake Michigan.
