A climate of tightening regulations, and the fact that TVA has already begun the upgrades, dictates finishing the upgrades, chief executive officer Tom Kilgore said.
Â“WeÂ’ve invested about a billion dollarsÂ… in East Tennessee,Â” Kilgore said. Â“It would be foolhardy not to complete those.Â”
TVA rested its case after KilgoreÂ’s testimony in federal court, where the state of North Carolina is suing to force the public electricity producer to reduce emissions by 2013. ThatÂ’s the deadline required of utilities within its borders.
Under cross-examination, Kilgore conceded that in the past TVA had made significant financial investments on plans it later abandoned, specifically the construction of a series of nuclear plants. The agency spent years building several that were later cancelled, leaving the agency deep in debt. Its debt is about $25 billion today.
TVA more recently announced it would put Â“scrubbersÂ” on its Colbert coal-fired plant in Alabama to lessen emissions there, and later switched its plans. Kilgore said the agency intends to put them on its John Sevier plant in East Tennessee instead.
TVA, the nationÂ’s largest public power producer, provides electricity to distributors throughout Tennessee and parts of six other states. Most comes from burning coal, with the second-largest amount from nuclear power.
North Carolina contends that air emissions from TVAÂ’s coal-burning plants are moving over the southern Appalachian Mountains and causing problems in that state that include cardio-vascular and respiratory illnesses and deaths.
Marc Bernstein, with the North Carolina attorney generalÂ’s office, questioned whether TVA would really take action without a law hanging over it. He also discussed the years 1983-93, when money was not spent on air pollution control equipment.
Since the U.S. Environmental Protection AgencyÂ’s Clean Air Interstate Rule was shot down in federal court this month, the agency has little reason to follow through with its current plans for reductions, the stateÂ’s suit argues.
Â“It does not change what weÂ’re going to do to clean up the air,Â” Kilgore insisted in court.
Earlier in the day, a top Tennessee air pollution chief chastised North Carolina for emissions at power plants within its own borders and defended TVA as a model operator of plants in Tennessee.
Quincy Styke, deputy director for Tennessee Division of Air Pollution Control, said TVAÂ’s operations are all properly permitted and he has no doubt that the agency will complete its plans.
He reacted with vigor when asked about North CarolinaÂ’s enactment of its Clean Smokestacks Act of 2002, which is requiring utilities in that state by 2013 to cap emissions of haze-, acid- and particle-producing sulfur dioxide and ozone-forming nitrogen oxide.
That stateÂ’s sulfur dioxide emissions rose to a high in 2005, Styke said.
Â“Tennessee has not enacted similar legislation because itÂ’s not necessary,Â” he said.
Â“We follow all the federal rule.Â… We donÂ’t need a statute. Tennessee has been about the business of controlling its emissions.Â”
North Carolina officials have said that emissions have been dropping significantly as private investor-owned utilities in the state phase in equipment as the deadline approaches.
Most of TVAÂ’s plants and employees are in Tennessee, though there are two plants in Alabama and two plants in Kentucky.
Witnesses on both TVAÂ’s and North CarolinaÂ’s side have testified that reductions of the agencyÂ’s emissions would benefit Tennesseans more, because more of its pollution affects Tennessee.
