EPA Approves, Proposes New Fuel Pathways

By Staff | August 12, 2013

The U.S. EPA has issued a supplemental final rule under the renewable fuel standard (RFS) that finalizes cellulosic pathways for biofuels made from giant reed and napier grass feedstock. The rule contains a life-cycle greenhouse gas (GHG) analysis of biofuels made from these feedstocks and establishes a system of registration, recordkeeping and reporting requirements designed to address concerns over the invasive potential of napier grass and giant reed. 

Through a separate rulemaking process, the EPA is also establishing a fuel pathway for ethanol produced from barley. In mid-July agency published a notice of data availability that outlined its analysis to qualify barley as a feedstock for two categories of fuel under the RFS; conventional renewable fuel that meets the 20 percent greenhouse gas (GHG) reduction threshold, and advanced biofuel that meets the 50 percent GHG reduction threshold.
