GRAND MARSH, WISCONSIN (WKZO) -- Here we go again. Enbridge said an oil spill in Wisconsin had forced it to shut down part of the main pipeline system delivering Canadian crude to U.S. refiners on Friday, a fresh blow for a firm already facing fierce criticism from regulators.Almost two years after the major spill in Calhoun County, Enbridge shut down Line 14 after a leak that it estimated at around 1,200 barrels of oil. Unlike the local spill, this time they shut it down, limiting the damage, The line, part of the Lakehead system, carries light crude oil to Chicago-area refineries.In west Michigan, while local government officials insist the river is clean enough to take your kids out for a boat ride, the River still poses a danger to residents according to environmental groups. .According to Kate Calarulli with the Sierra Club, despite an 800-million dollar clean up, 390 acres of contaminated land and water remain around the spill zone. She says this area is contaminated with highly toxic tar sands, causing heightened concerns about long-term health impacts.Calarulli says the Kalamazoo disaster and the spill in Wisconsin is a reminder that this can happen in any community where a tar sands pipeline might be located.
