Driving on Ohio Route 7 south of Steubenville near Brilliant, the first thing most people notice about the Cardinal Station power-generating facility is the snow-white plume emanating from the tall, thin dual stacks on the northern end of the station and from the shorter, stubbier tower to the south. The color of those plumes is significant. Long gone are the days when the stacks would send black smoke into the atmosphere. Thanks to more than $1 billion in investments in environmental equipment, that cloud is nearly all water vapor.
