1. New or reconstructed 2SLB stationary RICE >500 HP located at major sources; new or reconstructed 4SLB stationary RICE ≥250 HP located at major sources; and new or reconstructed CI stationary RICE >500 HP located at major sources

Reduce CO emissions and not using a CEMS

Conduct subsequent performance tests semiannually.¹

2. 4SRB stationary RICE ≥5,000 HP located at major sources

Reduce formaldehyde emissions

Conduct subsequent performance tests semiannually.¹

3. Stationary RICE >500 HP located at major sources and new or reconstructed 4SLB stationary RICE 250≤HP≤500 located at major sources

Limit the concentration of formaldehyde in the stationary RICE exhaust

Conduct subsequent performance tests semiannually.¹

4. Existing non-emergency, non-black start CI stationary RICE >500 HP that are not limited use stationary RICE

Limit or reduce CO emissions and not using a CEMS

Conduct subsequent performance tests every 8,760 hours or 3 years, whichever comes first.

5. Existing non-emergency, non-black start CI stationary RICE >500 HP that are limited use stationary RICE

Limit or reduce CO emissions and not using a CEMS

Conduct subsequent performance tests every 8,760 hours or 5 years, whichever comes first.
