The agency is accepting comments through December 9 on a draft environmental assessment of either installing emissions controls on two units at the plant, retrofitting them to bio-mass, or retiring them by the end of 2017.
TVA says it considered about 90 public comments in developing its draft assessment. It is asking for another round of comments from making a final
recommendation to its board. TVA must inform the Environmental Protection Agency of its decision by the end of the year.
Seven other coal-fired units at Shawnee aren't affected by the proposal. One unit was retired in 2010.
TVA spokesman Scott Brooks said the agency's current preferred alternative is installing emission controls.
