Sumner County, Tennessee
On March 12, 2013, TVA issued a final environmental assessment (EA), finding of no significant impact (FONSI), and decision memorandum on its proposal to construct and operate air pollution control equipment and associated facilities at its Gallatin Fossil Plant.
In order to meet the new Mercury and Air Toxics Standards, to comply with the April 2011 Clean Air Act Agreements with the U. S. Environmental Protection Agency, the States of Alabama, Kentucky, Tennessee, and North Carolina, and three environmental advocacy groups (the Sierra Club, the National Parks Conservation Association, Our Children's Earth Foundation), and to maintain a balanced portfolio of energy sources on the TVA power system in accordance with the Integrated Resource Plan, TVA proposes to construct and operate dry flue gas desulfurization ("scrubber"), selective catalytic reduction, pulse jet fabric filter, and activated carbon injection systems. TVA also proposes to construct and operate a landfill on the Gallatin plant site for the dry storage of the coal combustion residues. The proposed action will result in substantial reductions in emissions of sulfur dioxide, nitrogen oxides, mercury, and acid gases. As required by the National Environmental Policy Act, TVA developed an EA for this action. Based on the evaluations in the final EA, TVA determined that the proposed action would not result in significant impacts on the environment and has therefore issued the FONSI.
A draft of the EA was issued for public review and comment on October 17, 2012 for a 30-day review. In response to requests, TVA extended the comment period an additional two weeks to November 30. TVA subsequently agreed to accept late comments from several environmental advocacy groups until December 18, 2012. TVA received 1,199 comment submissions, including letters, emails, and submissions through the project website. Most of the comment submissions were pre-printed postcards or one of two form emails generated through advocacy group websites. TVA has carefully evaluated the comments and provided responses to them in Appendix E of the final EA.
