Bull Run Fossil Plant SCR System
Draft Environmental Assessment

TVA must meet new Title 1 Clean Air Act requirements. To achieve this goal, TVA proposes to install and operate selective catalytic reduction (SCR) technology at the Bull Run Fossil Plant in 2003. SCR technology is capable of providing the 90 percent NOx removal rate at Bull Run Fossil Plant needed to meet these requirements. SCR systems consist of various equipment and ductwork, a catalyst containing vanadium pentoxide, and an anhydrous ammonia system. The SCR system would be installed within the existing plant structure and the ammonia unloading and storage facility located within the plant site. TVA is considering two alternatives: completing the proposed action to install an SCR system, and the no action alternative, which would not allow TVA to meet its NOx reduction goals.
