The Environmental Protection Agency on Monday released a list of 44 coal-fired power plant waste sites in 10 states with a high hazard potential... Coal combustion waste stored...in impoundment sites at power plants contains toxins... The EPA said the high-hazard rating at the 44 sites didn't mean that they were structurally weak, but rather that a failure would probably kill people nearby.
