Massena, NY, Aug 31, 2010 — The post-bailout arm of General Motors that's in charge of liquidating failed assets of the car-maker wants to tear down the Powertrain plant in Massena. The plant closed for good last year. But the buildings, the equipment, and the soil underneath is contaminated with toxic PCB oil. Federal environment officials now say Motors Liquidation Company has to clean it all up before demolition can begin. As David Sommerstein reports, the extent of the contamination has some former workers and the Massena community worried.
