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.
