  2. Existing spark ignition 4SLB RICE > 500 HP at Major Sources;
  3. Existing emergency RICE > 500 HP at Major Sources that operate ≤ 15 hours/year for emergency demand response and local reliability voltage deviations;
  4. Existing limited use RICE > 500 HP at Major Sources;
  5. Existing landfill or digester gas RICE > 500 HP at Major Sources.


Not Subject to this Subpart:

  1. Existing residential, commercial, and institutional emergency RICE at Area Sources used ≤ 15 hours/year for emergency demand response, provided they are not also used for local reliability.
