The EPA proposed rule to set GHG emission performance standards for fossil-fuel powered electric generating units, was published in the Federal Register yesterday after almost three months since EPA first issued it. These new proposed standards reflect separate determinations of the best system of emission reduction (BSER) adequately demonstrated for utility boilers and IGCC units and for natural gas-fired stationary combustion turbines. Whether EPA plans to issue a supplemental notice for public comment on the technical feasibility of carbon capture and sequestration is unclear. The proposed rule sets forth a performance standard for new IGCC plants and utility boilers based on the utilization of partial CCS capabilities (1,100 lbs CO2/MWh). The proposal also set limits for natural gas combustion turbines based on the capabilities of advanced natural gas combined cycle technology (e.g., 1,000 lbs CO2/MWh and 1,100 lbs CO2/MWh depending on the size of the unit.) The full text of the proposal can be found here: https://www.federalregister.gov/articles/2014/01/08/2013-28668/standards-of-performance-for-greenhouse-gas-emissions-from-new-stationary-sources-electric-utility.
