SHREVEPORT, La., Jan. 22, 2010 – The Arkansas Pollution Control and Ecology Commission today affirmed the air permit for the John W. Turk, Jr. Power Plant now under construction in southwest Arkansas by AEP Southwestern Electric Power Company (SWEPCO), a unit of American Electric Power (NYSE: AEP).

The commission approved the recommended decision of its administrative hearing officer, who conducted hearings in June 2009 in an appeal by plant opponents.

The air permit, issued by the Arkansas Department of Environmental Quality (ADEQ) on Nov. 5, 2008, regulates the plant’s main steam generating unit and other emission sources at the plant.

“The ‘ultra-supercritical’ coal combustion technology and state-of-the art emission controls will enable the Turk Plant to meet emission limits that are among the most stringent ever permitted for a pulverized coal unit,” said Paul Chodak, SWEPCO president and chief operating officer. “We are certainly pleased that the Pollution Control and Ecology Commission upheld the air permit and confirmed the extensive work of the Arkansas Department of Environmental Quality.”

Estimated completion date for the $1.6 billion 600-megawatt facility is Oct. 1, 2012. SWEPCO’s 73 percent share of the plant is $1.1 billion and 440 megawatts. The plant is under construction between Fulton and McNab in Hempstead County, Ark.

“The Turk Plant will be one of the cleanest, most efficient coal-fueled plants in the United States,” Chodak said. “This facility represents the most affordable choice to meet the future energy needs of SWEPCO’s customers.”

SWEPCO serves more than 473,500 customers in three states, including 113,500 in western Arkansas, 180,000 in Northwest Louisiana, and 180,000 in East and North Texas. SWEPCO’s headquarters are in Shreveport, La. News releases and other information about SWEPCO can be found at www.swepco.com.
