Fossil Plant Units 1 Through 9
Reduction Systems for Nitrogen Oxide Control
Draft Environmental Assessment
TVA must meet new Title 1 Clean Air Act requirements. As alternatives to achieve this goal, TVA proposes to install and operate either a system of selective catalytic reduction (SCR) technology or a hybrid system of SCRs and NOx Tech technology at the Kingston Fossil Plant (KIF) over a two-year period from June 2002 to April 2004.
These technologies would provide the NOx removal rates at KIF needed to meet the requirements. SCR systems consist of various equipment and ductwork, a catalyst containing vanadium pentoxide, and an anhydrous ammonia system. The NOx Tech system involves less construction within the plant but requires a supply of natural gas. The SCRs and NOx Tech equipment would be installed within the existing plant structure and the ammonia unloading and storage facility located within the plant site. Off-site work involving the construction and operation of the natural gas pipeline would occur only if the alternative including NOx Tech equipment is chosen. The No Action alternative would not allow TVA to meet its NOx reduction goals.
