This Notice provides an opportunity to comment on EPA's draft analysis of the lifecycle greenhouse gas (GHG) emissions of ethanol that is produced using barley as a feedstock. EPA's draft analysis indicates that ethanol produced from barley has an estimated lifecycle GHG emissions reduction of 47% as compared to baseline conventional fuel when the barley ethanol is produced at a dry mill facility that uses natural gas for all process energy, uses electricity from the grid, and dries up to 100% of distillers grains. Such barley ethanol would therefore meet the minimum 20% GHG emissions reduction threshold for conventional biofuels under the Clean Air Act Renewable Fuel Standard (RFS) program. In addition, EPA analyzed two potential options for producing barley ethanol that would meet the 50% GHG emissions reduction threshold for advanced biofuels. Ethanol produced from dry- milling barley meet the advanced biofuels GHG reduction threshold if it is produced at a facility that uses no more than 30,700 Btu of natural gas for process energy, no more than 4,200 Btu of biomass from barley hulls or biogas from landfills, waste treatment plants, barley hull digesters, or waste digesters for process energy, and no more than 0.84 kWh of electricity from the grid for all electricity used at the renewable fuel production facility, calculated on a per gallon basis. Ethanol produced from dry-milling barley can also meet the advanced biofuel GHG reduction threshold if the production facility uses no more than 36,800 Btu of natural gas for process energy and also uses natural gas for on-site production of all electricity used at the facility other than up to 0.19 kWh of electricity from the grid, calculated on a per gallon basis.
