This Technical Support Document (TSD) discusses costs and emission reduction potential for common electric generating unit (EGU) NO_X emission control systems.  Specifically, this TSD explores three topics:

1. The appropriate representative cost resulting from “widespread” implementation of a particular NO_X emission control technology;
2. The NO_X emission rates commonly achievable by “fully operating” emission control equipment; and,
3. The time required to install and/or restore an emission control system to full operation.

These estimates form the basis for modeling costs and emission reductions within IPM v 5.14 and 5.15.
