The Environmental Protection Agency Thursday finalized renewable volumes under the Renewable Fuel Standard for 2020. Through the action, EPA says it has “fulfilled yet another key promise” to farmers, however, corn and biofuel producers disagree. The EPA did not make changes to the proposal, as requested by the biofuels industry. The final rule will use a three-year rolling average of recommended small refinery exemptions by the Department of Energy to account for waived gallons. Farm groups told the EPA during the comment period to account for the actual number of waived gallons, rather than the DOE recommendations. The EPA says conventional biofuel volumes, primarily met by corn ethanol, will be maintained at the 15 billion gallon target set by Congress for 2020. Cellulosic biofuel volumes for 2020, and thus advanced biofuel volumes, will increase by almost 170 million gallons over the 2019 standard. Biomass-based diesel volumes for 2021 will be equivalent to the standard for 2020, and total RVO gallons for 2020 is 20.09 billion gallons.
