EPA Sues TVA Over Pollution Controls
LCG, May 23, 2002--The Environmental Protection Agency argued before a three-judge panel on Tuesday that the Tennessee Valley Authority broke the law by not installing pollution control equipment at its coal-fired plants.According to EPA attorneys, such equipment should have been installed when coal plants' output capacity was increased. The TVA, which serves customers in seven Southeastern states, told the panel that the EPA's argument that it violated the Clean Air Act over the past 20 years was based on that agency's rewriting the rules well after the passage of the original law.The EPA asked that a federal order issued to the TVA to bring about compliance with the Clean Air Act be upheld. A Department of Justice lawyer speaking for the EPA, J. Steven Rogers, said, "TVA basically ignored the law, like most of the industry." Harriet A. Cooper, arguing for the TVA, cited $2.5 billion the publicly owned utility had spent on pollution reduction at its plants, and said that a ruling against it would lead to fewer pollution controls being installed, and cause it to have to raise its rates. The work done at its plants constituted maintenance, not major upgrades, and therefore did not require pollution control equipment installation, she said.A ruling is expected this summer. Approximately a dozen similar cases are underway against utilities providing service in the South and Midwest.
