Section 217.704  Applicability

The following fossil fuel-fired stationary boilers, combustion turbines or combined cycle systems are electrical generating units (EGUs) and shall be subject to this Subpart on and after May 1, 2003:

a)         Any unit serving a generator that has a nameplate capacity greater than 25 MWe and produces electricity for sale, excluding those units listed in Appendix D of this Part and any new unit at a source listed in Appendix D of this Part.

b)         Any unit with a maximum design heat input that is greater than 250 mmbtu/hr that commences operation on or after January 1, 1999, serving at any time a generator that has a nameplate capacity of 25 MWe or less and has the potential to use more than 50% of the potential electrical output capacity of the unit. Fifty percent of a unit's potential electrical output capacity shall be determined by multiplying the unit's maximum design heat input by 0.0488 MWe/mmbtu.  If the size of the generator is greater than this calculated number, the unit is an EGU subject to the provisions of this Subpart.
