Code of Federal Regulations Title 40. Protection of Environment 40 CFR Pt. 60, Subpt. TTTT, Tbl. 2 Table 2 to Subpart TTTT of Part 60—CO 2 Emission Standards for Affected Stationary Combustion Turbines That Commenced Construction After January 8, 2014 and Reconstruction After June 18, 2014 (Net Energy Output-Based Standards Applicable as Approved by the Administrator)

Newly constructed or reconstructed stationary combustion turbine that supplies more than its design efficiency or 50 percent, whichever is less, times its potential electric output as net-electric sales on both a 12-operating month and a 3-year rolling average basis and combusts more than 90% natural gas on a heat input basis on a 12-operating-month rolling average basis

450 kg of CO₂ per MWh of gross energy output (1,000 lb CO₂/MWh); or

470 kilograms (kg) of CO₂ per megawatt-hour (MWh) of net energy output (1,030 lb/MWh).

Newly constructed or reconstructed stationary combustion turbine that supplies its design efficiency or 50 percent, whichever is less, times its potential electric output or less as net-electric sales on either a 12-operating month or a 3-year rolling average basis and combusts more than 90% natural gas on a heat input basis on a 12-operating-month rolling average basis

50 kg CO₂ per gigajoule (GJ) of heat input (120 lb CO₂/MMBtu).

Newly constructed and reconstructed stationary combustion turbine that combusts 90% or less natural gas on a heat input basis on a 12-operating-month rolling average basis

50 kg CO₂/GJ of heat input (120 lb/MMBtu) to 69 kg CO₂/GJ of heat input (160 lb/MMBtu) as determined by the procedures in § 60.5525.
