[Note: Numerical values of 1,000 or greater have a minimum of 3 significant figures and numerical values of less than 1,000 have a minimum of 2 significant figures]

Affected EGU category CO2 emission standard
Base load combustion turbinesFor 12-operating month averages beginning before January 2032, 360 to 560 kg CO2/MWh (800 to 1,250 lb CO2/MWh) of gross energy output; or 370 to 570 kg CO2/MWh (820 to 1,280 lb CO2/MWh) of net energy output as determined by the procedures in § 60.5525a.
For 12-operating month averages beginning after December 2031, 43 to 67 kg CO2/MWh (100 to 150 lb CO2/MWh) of gross energy output; or 42 to 64 kg CO2/MWh (97 to 139 lb CO2/MWh) of net energy output as determined by the procedures in § 60.5525a.
Intermediate load combustion turbines530 to 710 kg CO2/MWh (1,170 to 1,560 lb CO2/MWh) of gross energy output; or 540 to 700 kg CO2/MWh (1,190 to 1,590 lb CO2/MWh) of net energy output as determined by the procedures in § 60.5525a.
Low load combustion turbinesBetween 50 to 69 kg CO2/GJ (120 to 160 lb CO2/MMBtu) of heat input as determined by the procedures in § 60.5525a.
