USDA Opens New Application Window for HBIIP. The USDA is scheduled to open a new $100 million, 90-day application window for the Higher Blends Infrastructure Incentive Program on Aug. 23, according to a document published in the Federal Register on Aug. 22. The HBIIP is a competitive grant program that aims to significantly increase the sales and use of higher blends of ethanol and biodiesel by expanding the infrastructure for renewable fuels derived from U.S. agricultural products. Investments made under HBIIP aim to help transportation fueling and biodiesel distribution facilities convert to higher ethanol and biodiesel blends by sharing the costs related to the installation of fuel pumps, related equipment and infrastructure. Under the program, higher blends include ethanol blends of greater than 10 percent and biodiesel blends of greater than 5 percent.
