The U.S. Department of Agriculture (USDA) has issued a notice calling for public comment on proposed loan and grant programs that would increase production of advanced biofuels. 75 Fed. Reg. 20,043 (04/16/10). The notice actually proposes three separate rules establishing (i) a rolling application process that would consider loan guarantee requests up to $250 million; (ii) procedures for eligible biorefineries to receive payment for installing new systems that encourage renewable biomass use and replace fossil fuels; and (iii) a payment program for eligible advanced biofuel producers who produce biofuels from renewable biomass, excluding corn kernel starch. USDA requests comments by June 15, 2010.
