"...Pollution drifting from its [TVA] coal-fired power plants, N.C. Attorney General Roy Cooper says, makes the nation's largest public power company a public nuisance. Cooper gets his chance to prove it today in a federal court in Asheville. ...Cooper wants TVA to install pollution controls similar to those North Carolina required of Duke Energy and Progress Energy in 2002. The estimated cost to TVA: $516 million a year.  Reducing wind-blown pollutants from TVA plants in Tennessee, Alabama and Kentucky would prevent 99 premature deaths, 19,000 asthma attacks and 2,300 lost school days a year in North Carolina, the state says in court filings. Each year of delay, an expert witness is expected to testify, costs the state and its residents $672 million in health costs."
