Location: Stratton, on the Ohio River in Jefferson County. Price tag: $1.8 billion. Completion date: Scrubbers and other anti-pollution equipment should be operating by mid-2010. Work is 95 percent complete. Purpose: To reduce soot, sulfur dioxide and nitrogen oxide emissions. Sulfur dioxide contributes to acid rain and soot hurts human health. Nitrogen oxide contributes to unhealthy smog. Project will cut sulfur dioxide by 95 percent and nitrogen oxide by 90 percent. Power output: 2,233 megawatts, enough to power 1.3 million homes. The plant burns 7 million tons of coal a year. Reason for project: FirstEnergy is under a 2005 federal consent decree to clean up the plant. Additional work: FirstEnergy made $55 million in anti-pollution improvements at the Eastlake plant in Lake County and the Bruce Mansfield Power Station in Shippingport, Pa. It also agreed to largely switch from coal to wood pellets at the R.E. Burger Power Plant in Belmont County. That project has a $200 million price tag and a Dec. 31, 2012, deadline.
