Louisville Gas & Electric says a piece of machinery that malfunctioned last weekend at their Cane Run Power Station should be up and running next week.Residents complained after clouds of dust were visible above the plant’s landfill in southwest Louisville. They’ve documented instances of ash leaving the landfill and contaminating their property in the past.The company took the sludge processing plant, which mixes coal ash with lime to create a cement-like material, out of commission. More dust was visible yesterday evening, but LG&E spokeswoman Chris Whelan says the dust was released in the process of cleaning and repairing the machine."We are going to install a fluidization system, but we had to get all the ash that was in there when we shut it off abruptly—we had to get that out of there before we could do the repairs," she said.Whelan says the machine should be fixed and functioning normally next week.
