On July 2, 2021, U.S. Representatives Angie Craig (D-MN) and Randy Feenstra (R-IA) introduced a bill called the Small Refinery Exemption Clarification Act of 2021. The bill clarifies that only oil refineries that have been continuously receiving small refinery exemptions (SRE) since 2011 should be eligible to petition for extensions of renewable fuel blending requirement exemptions. The SRE Clarification Act follows the Supreme Court’s decision in late June 2021 that, according to Representatives Craig and Feenstra, could negatively influence the biofuels industry by making it easier for oil refineries to avoid Renewable Fuel Standard (RFS) blending requirements. Representative Craig stated that “it is vital that we continue to support the clean biofuels industry as we reduce the carbon intensity of our transportation sector and make important investments across rural America.” Representative Feenstra emphasized that “we must erase ambiguities and ensure oil refineries are not able to take shortcuts when it comes to blending biofuels.”
