“The steady erosion of the nation's clean air laws under the Bush administration has inspired Roy Cooper, North Carolina's attorney general, to adopt an unusual legal strategy to force out-of-state power plants to stop sending air pollution into his state…The suit seeks no monetary damages. It simply asks the court to order the T.V.A. to install up-to-date emissions controls on the sulfur dioxide, nitrogen oxides and mercury from its coal-fired power plants. These pollutants kill trees; poison streams; create haze in national parks, like the Great Smoky Mountains park; and contribute heavily to respiratory illnesses…Mr. Cooper's resourcefulness is to be admired…T.V.A. would do well to reach an amicable agreement.”
