TVA approves additional coal-fired emissions controls in Ky.

Tennessee Valley Authority TVA emissions controls air pollution coal-fired Environmental Protection Agency EPA

The Board of Directors for the Tennessee Valley Authority (TVA) voted to add more air emissions controls to units 1 and 4 at the Shawnee Fossil Plant in Kentucky.

The additional controls will be installed before Dec. 31, 2017 and are estimated to cost $185 million. They will reduce nitrogen oxide and sulfur dioxide emissions.

TVA was required to either retire or install additional controls on the units, or convert the units to burn biomass instead of coal as part of a 2011 Clean Air Agreement with the U.S. Environmental Protection Agency (EPA). TVA completed an environmental assessment and determined that either retiring the units or adding controls would have no significant environmental impact.

The Shawnee plant has nine operating units that generate 1,206-MW of power. The remaining units are not affected by this decision and already have sufficient controls to meet EPA standards.
